Definitions
- the invention concerns a fastener to be applied to a threaded stud with a sleeve-like clamping element that has a cavity extending in the direction of its longitudinal axis to accommodate the threaded stud and at least one clamping region that can deform into the cavity and that forms at least one clamping ramp inclined toward the longitudinal axis on the outside of the clamping element, and with a clamping sleeve that can be pushed onto the clamping element and in the installed state grips around the clamping element, wherein an inner surface of the clamping sleeve works with the clamping ramp such that the clamping region reaches a clamping position that is deformed into the cavity and holds the threaded body, wherein the clamping element has a flange at its forward end in the direction of installation.
- Fasteners of the specified type are used particularly in automobile manufacture to fasten parts to threaded studs.
- the distinguishing feature of these fasteners is that they can be brought into the fastening position on a threaded stud solely through an axial motion and can be securely attached to the threaded stud by pushing on the clamping sleeve, for example by striking.
- the connection can be released again by unscrewing the fastener from the threaded stud like a nut.
- the cross-section of the clamping element is polygonal and its wall has radially resilient wall sections that deform radially outward when the clamping element is pushed onto the threaded stud.
- the clamping sleeve is formed onto one end of the clamping element such that it can break off and its inner cross-section is dimensioned such that it can be pushed over the outside of the clamping element, whereby the radially resilient wall sections are deformed inward such that the threads of the threaded stud can be partially formed into the resilient wall sections.
- latching sections are formed on the flange of the clamping element that extend in the direction of the clamping sleeve and grip around a latching recess on the outside of the clamping sleeve.
- the outside of the clamping sleeve is hexagonal so that a wrench may be used to rotate the fastener.
- a torque produced at the clamping sleeve is transmitted to the polygonal wall sections of the clamping element by the polygonal inner surface of the clamping sleeve. Because of the resilience of the wall sections, this leads to an increase in the radial clamping force, thus making it more difficult to turn the fastener.
- the object of the invention is to create a fastener of the aforementioned type that is characterized by ease of use.
- the object is attained by the invention in that there are arranged, on the flange and on the end of the clamping sleeve facing the flange, coupling elements and mating coupling elements that interlock when the clamping sleeve is located on the clamping element in the assembled state, and that prevent rotation of the clamping sleeve relative to the clamping element.
- the clamping sleeve in the installed state is nonrotatably fixed to the clamping element by the coupling elements so that relatively high torques can be transmitted from the clamping sleeve to the clamping element without significantly affecting rotatability of the fastener relative to the threaded stud.
- a preferred embodiment of the invention provides that the coupling elements are composed of axial projections on the end face of the clamping sleeve and the mating coupling elements are composed of recesses in the flange of the clamping element that accommodate the projections. This simplifies manufacture of the fastener as an injection-molded plastic part and the coupling elements can be made sufficiently large without difficulty.
- the invention is not limited to such a design. Rather, projections that work in conjunction with recesses in the clamping sleeve may also be provided on the clamping element or its flange.
- the initial inside diameter of the clamping element's cavity is equal to or greater than the outer diameter of the threaded stud so that the clamping element can be brought into position on the threaded stud by axial sliding and without great resistance.
- High retention or pull-off forces can be achieved according to another proposal of the invention in that the clamping region of the clamping element has, on its inner side that works together with the threaded stud, at least one rib that is designed to engage in a thread groove of the threaded stud. Efficacious positive locking between the clamping element and the threaded stud can be achieved by one or more ribs, which preferably are shaped to match the stud thread profile, without the need for high contact forces between the clamping region of the clamping element and the threaded stud. In addition to high pull-off forces, this design has the further advantage that no high clamping forces need be generated during assembly of the clamping sleeve, so the resistance to be overcome to move the clamping sleeve can remain correspondingly small.
- the flange of the clamping element is provided with a toothed contact surface on its forward side facing away from the clamping region.
- this toothing effects an increase in the frictional force between the flange and the mating contact surface that works together with the flange, which serves to increase the loosening torque, i.e. the torque required to unscrew an installed fastener.
- the increase in the loosening torque makes the installed fastener more secure against coming loose by itself.
- At least one flexible latching finger extending forward toward the flange can be provided, which carries at its end a catch that works in conjunction with a shoulder of the clamping element.
- the shoulder is formed here by an undercut in an opening that is provided in the flange of the clamping element, and in which the latching finger engages in the installed state of the clamping sleeve.
- the clamping sleeve can be joined to the clamping element as a single piece by means of a predetermined breaking point.
- Manufacture of the clamping sleeve and clamping element for example of plastic, can thus be accomplished in a single mold, and both parts are always guaranteed to be available at installation.
- an impact in the direction of the stud axis separates the clamping sleeve from the clamping element and simultaneously moves it into the installed position. This process makes possible a short installation time and can be performed equally well by hand or with the aid of automatic assembly devices.

Abstract
A fastener includes a sleeve-like clamping element having a cavity extending in the direction of its longitudinal axis which accommodates a threaded stud. At least one clamping region is deformable into the cavity forming at least one clamping ramp inclined toward the longitudinal axis on an outside of the clamping element. A clamping sleeve pushed onto the clamping element in an installed state grips around the clamping element. A clamping sleeve inner surface cooperates with the clamping ramp so the clamping region reaches a clamping position deformed into the cavity to hold the threaded stud. The clamping element has a forward end flange in an installation direction. Coupling elements and mating coupling elements arranged on the flange and a clamping sleeve end facing the flange interlock in the installed state, preventing rotation between the clamping sleeve and clamping element.
Description
- This application is a divisional of U.S. patent application Ser. No. 10/994,210, currently allowed, filed Nov. 19, 2004, which claimed the benefit of German Patent Application No. 10357024.1, filed Dec. 3, 2003. The disclosures of the above applications are incorporated herein by reference.
- The invention concerns a fastener to be applied to a threaded stud with a sleeve-like clamping element that has a cavity extending in the direction of its longitudinal axis to accommodate the threaded stud and at least one clamping region that can deform into the cavity and that forms at least one clamping ramp inclined toward the longitudinal axis on the outside of the clamping element, and with a clamping sleeve that can be pushed onto the clamping element and in the installed state grips around the clamping element, wherein an inner surface of the clamping sleeve works with the clamping ramp such that the clamping region reaches a clamping position that is deformed into the cavity and holds the threaded body, wherein the clamping element has a flange at its forward end in the direction of installation.
- Fasteners of the specified type are used particularly in automobile manufacture to fasten parts to threaded studs. The distinguishing feature of these fasteners is that they can be brought into the fastening position on a threaded stud solely through an axial motion and can be securely attached to the threaded stud by pushing on the clamping sleeve, for example by striking. The connection can be released again by unscrewing the fastener from the threaded stud like a nut. Moreover, it is possible to increase the axial clamping force of an established connection by turning the fastener in the direction of tightening.
- In a fastener of the specified type known from DE 101 33 063 A1, the cross-section of the clamping element is polygonal and its wall has radially resilient wall sections that deform radially outward when the clamping element is pushed onto the threaded stud. The clamping sleeve is formed onto one end of the clamping element such that it can break off and its inner cross-section is dimensioned such that it can be pushed over the outside of the clamping element, whereby the radially resilient wall sections are deformed inward such that the threads of the threaded stud can be partially formed into the resilient wall sections. To hold the clamping sleeve in the assembled position, latching sections are formed on the flange of the clamping element that extend in the direction of the clamping sleeve and grip around a latching recess on the outside of the clamping sleeve. The outside of the clamping sleeve is hexagonal so that a wrench may be used to rotate the fastener. A torque produced at the clamping sleeve is transmitted to the polygonal wall sections of the clamping element by the polygonal inner surface of the clamping sleeve. Because of the resilience of the wall sections, this leads to an increase in the radial clamping force, thus making it more difficult to turn the fastener.
- The object of the invention is to create a fastener of the aforementioned type that is characterized by ease of use.
- The object is attained by the invention in that there are arranged, on the flange and on the end of the clamping sleeve facing the flange, coupling elements and mating coupling elements that interlock when the clamping sleeve is located on the clamping element in the assembled state, and that prevent rotation of the clamping sleeve relative to the clamping element.
- In the fastener according to the invention, the clamping sleeve in the installed state is nonrotatably fixed to the clamping element by the coupling elements so that relatively high torques can be transmitted from the clamping sleeve to the clamping element without significantly affecting rotatability of the fastener relative to the threaded stud. This has the advantage that unscrewing of the fastener is made easier and that comparatively high tightening torques and corresponding high loosening torques can be produced and/or transmitted with the fastener in accordance with the invention.
- A preferred embodiment of the invention provides that the coupling elements are composed of axial projections on the end face of the clamping sleeve and the mating coupling elements are composed of recesses in the flange of the clamping element that accommodate the projections. This simplifies manufacture of the fastener as an injection-molded plastic part and the coupling elements can be made sufficiently large without difficulty. However, the invention is not limited to such a design. Rather, projections that work in conjunction with recesses in the clamping sleeve may also be provided on the clamping element or its flange.
- In accordance with another proposal of the invention, provision can be made that the initial inside diameter of the clamping element's cavity is equal to or greater than the outer diameter of the threaded stud so that the clamping element can be brought into position on the threaded stud by axial sliding and without great resistance. This refinement makes it possible to keep the assembly forces for placement of the fastener on a threaded stud especially low; this also contributes to improving the fastener's ease of use.
- High retention or pull-off forces can be achieved according to another proposal of the invention in that the clamping region of the clamping element has, on its inner side that works together with the threaded stud, at least one rib that is designed to engage in a thread groove of the threaded stud. Efficacious positive locking between the clamping element and the threaded stud can be achieved by one or more ribs, which preferably are shaped to match the stud thread profile, without the need for high contact forces between the clamping region of the clamping element and the threaded stud. In addition to high pull-off forces, this design has the further advantage that no high clamping forces need be generated during assembly of the clamping sleeve, so the resistance to be overcome to move the clamping sleeve can remain correspondingly small.
- According to another proposal of the invention, provision can be made that the flange of the clamping element is provided with a toothed contact surface on its forward side facing away from the clamping region. Particularly when the mating contact surface is made of a more or less resilient material, this toothing effects an increase in the frictional force between the flange and the mating contact surface that works together with the flange, which serves to increase the loosening torque, i.e. the torque required to unscrew an installed fastener. The increase in the loosening torque makes the installed fastener more secure against coming loose by itself. There is no danger here of disadvantages with respect to ease of use, however, since the design of the fastener according to the invention facilitates the transmission of high torques without an increase in clamping forces.
- To secure the clamping sleeve in the installed position on the clamping element, according to another suggestion of the invention at least one flexible latching finger extending forward toward the flange can be provided, which carries at its end a catch that works in conjunction with a shoulder of the clamping element. Preferably, the shoulder is formed here by an undercut in an opening that is provided in the flange of the clamping element, and in which the latching finger engages in the installed state of the clamping sleeve. This design protects the latching point of the latching finger from external access so that the clamping sleeve cannot be separated from the clamping element once the fastener is installed. Only after the fastener has been unscrewed is the catch of the latching finger accessible on the front of the flange and can be unlocked with the aid of a tool if necessary.
- According to another suggestion of the invention, the clamping sleeve can be joined to the clamping element as a single piece by means of a predetermined breaking point. Manufacture of the clamping sleeve and clamping element, for example of plastic, can thus be accomplished in a single mold, and both parts are always guaranteed to be available at installation. It is advantageous for the predetermined breaking point to be located between the rearward end of the clamping element and the forward end of the clamping sleeve in the direction of installation. At installation, after placement of the clamping element on the threaded stud, an impact in the direction of the stud axis separates the clamping sleeve from the clamping element and simultaneously moves it into the installed position. This process makes possible a short installation time and can be performed equally well by hand or with the aid of automatic assembly devices.
- The invention is explained in detail below using an example embodiment that is illustrated in the drawings. The drawings show:
-
FIG. 1 is a side view of a fastener according to the invention; -
FIG. 2 is a longitudinal section through the fastener according to the invention along line II-II inFIG. 3 ; -
FIG. 3 is a longitudinal section through the fastener according to the invention along line III-III inFIG. 1 ; and -
FIG. 4 is a longitudinal section of the fastener in the installed state. - The
fastener 1 shown in the drawings is made of plastic in a single piece and comprises aclamping element 2 and aclamping sleeve 3. Theclamping element 2 has a sleeve-shaped section 4 and a plate-shaped flange 5 located on one end of thesection 4. Theflange 5 has, on the outside edge of its side facing away from thesection 4, saw-tooth-like toothing 6. The teeth in thetoothing 6 are oriented such that, when in contact with a mating surface, they increase the resistance to rotation in the direction in which the fastener located on a threaded stud can be unscrewed. - The
clamping element 2 has acavity 7 to accommodate a threaded stud. Thecavity 7 is composed essentially of a cylindrical bore that passes through thesection 4 and theflange 5, wherein the center axis of the bore coincides with the longitudinal axis of theclamping element 2. Thesection 4 of theclamping element 2 forms a closedring 8 at its end opposite theflange 5. Between thering 8 and theflange 5, the wall of thesection 4 is divided bylongitudinal slots 9 into twoopposing clamping regions 10 and two opposing connectingregions 11. Each connectingregion 11 has in its center onelongitudinal slot 12. Thelongitudinal slots 12 reduce the bending resistance of the connectingregions 11 and facilitate deformation transverse to the longitudinal extent thereof. On their outer side, theconnecting regions 11 are provided with a shallow, convex arch whose apex lies in the center between the ends of the connectingregions 11. - The wall sections of the
clamping regions 10 are separated from theflange 5 at their end opposite thering 8 byrecesses 13, which extend transverse to the longitudinal axis of thefastener 1. This allows theclamping region 10 to be pressed into thecavity 7 under elastic deformation inward by relatively small forces acting on it from outside. In their initial position, shown inFIG. 3 , the clampingregions 10 are angled outward at approximately 10° to the longitudinal axis such that their ends adjacent to theflange 5 are a relatively great distance from one another. As a result, the outer sides of the clampingregions 10 form clamping ramps 14 that are inclined toward the longitudinal axis, and that work together with the associated inside surfaces of the clampingsleeve 3 during installation of thefastener 1. On their inside, the clampingregions 10 have saw-tooth-like ribs 15, whose shape and size are matched to the thread of a fastening stud that works in conjunction with thefastener 1. In addition, theribs 15 of the opposingclamping regions 10 are offset longitudinally with respect to one another to match the thread pitch. - The
ring 8 has an outer contour in the shape of a hexagonal prism. At its end facing away from theflange 5, thering 8 is connected to theadjacent clamping sleeve 3 bypredetermined breaking points 16 in the form of thin-walled fins. The clampingsleeve 3 has acentral opening 17, which likewise has the shape of a hexagonal prism, and whose size is matched to the size of thering 8 such that thering 8 can enter theopening 17 without significant resistance and can be moved along theopening 17 while maintaining its orientation. On its outside, the clampingsleeve 3 has asection 18 designed as a hexagonal prism that serves for placement of a wrench. Acollar 19 adjoins thesection 18. - Two
projections 20 are molded opposite one another on the end face of the clampingsleeve 3 that faces theclamping element 2; they have essentially the shape of roof prisms extending in the tangential direction. Theprojections 20 form coupling elements that work together with mating coupling elements on theflange 5. In order to form the mating coupling elements, theflange 5 has twoopenings 21 in a mirror image arrangement into which theprojections 20 project when the clampingsleeve 3 is brought into the installed position shown inFIG. 4 . The interlocking of the coupling elements and mating coupling elements produces a nonrotating connection between the clampingsleeve 3 and theclamping element 2 and permits the transmission of relatively high torques from the clampingsleeve 3 to theclamping element 2. - Provided on the
collar 19 of the clampingsleeve 3 are latchingfingers 22 that are each radially outside theprojections 20 and extend toward theflange 5 parallel to the longitudinal axis. Located at the end of each of the latchingfingers 22 on the inside is acatch 23.Openings 24 are provided in theflange 5 for the latchingfingers 22. Theopenings 24 are provided with an undercut, which forms ashoulder 25. When the clampingsleeve 3 is brought into its installed position on the clamping element, the ends of the latchingfingers 22 project into theopenings 24 and thecatches 23 arrive at a position wherein they grip around theshoulders 25. In this way, the clampingsleeve 3 is held in place in the installed position on theclamping element 2. -
FIG. 4 shows thefastener 1 in its installed position on a threadedstud 30. The threadedstud 30 is fastened to acomponent 31 and extends through a bore in asecond component 32 resting upon thecomponent 31, and into thefastener 1. Thefastener 1 rests with theteeth 6 of theflange 5 directly on thecomponent 32 and presses the latter against thecomponent 31. Here, thefastener 1 is supported on the threadedstud 30 with the aid of the clampingregions 10, which engage the thread grooves of the stud thread with theirribs 15 and are held in this position by the clampingsleeve 3 pushed onto the clampingregion 10. - The installed position of the
fastener 1 shown inFIG. 4 is reached in the following way: first, thefastener 1 in the initial state shown inFIGS. 1-3 is pushed onto the threadedstud 30, which is possible without significant resistance since thecavity 7 is dimensioned large enough that neither the clampingregion 10 nor the connectingregion 11 need by radially deformed outward during placement on the threadedstud 30. If installation is to take place on the underside of a component, it can however be useful to dimension the distance between at least two opposingribs 15 of the clampingregions 10 to be initially somewhat smaller than the outside diameter of the threaded stud so that thefastener 1 is held fast after being placed on the threadedstud 30. As soon as theflange 5 of thefastener 1 comes in contact with thecomponent 32, thepredetermined breaking points 16 can be broken by an axial force acting on the clamping sleeve and directed toward thecomponent 32, for example a hammer blow, and the clampingsleeve 3 can be moved into contact with theflange 5. In this process, the clampingelement 2 projects into theopening 17 of the clampingsleeve 3 and the inner surfaces of theopening 17, acting in conjunction with the clamping ramps 14, press the clampingregions 10 into thecavity 7 and firmly against the threadedstud 30 wherein theribs 15 engage the grooves of the stud thread. Moreover, provision can be made that the center sections of the connectingregions 11 are likewise bent radially inward by the inner surfaces of theopening 17, so that they rest against the thread pitches of the stud thread without play and with preloading. In addition, theprojections 20 engage theopenings 21 and the latchingfingers 22 project into theopenings 24, while thecatches 23 snap into the undercut behind theshoulders 25. - If the fastening of the
component 32 is to be undone, this can only be accomplished by unscrewing thefastener 1 from the threadedstud 30. To do so, a wrench is placed on the clampingsleeve 3 and is turned in the direction of removal after overcoming the loosening torque produced by the contact of thetoothing 6 with thecomponent 32 and the thread friction. During this process, the loosening torque is transmitted from the clampingsleeve 3 to theclamping element 2 by means of theprojections 20 engaging theopenings 21.
Claims (9)
1. A threaded element engagement fastener, comprising:
a tubular clamp having first and second ends and a cavity created through the clamp, the cavity extending substantially parallel to a longitudinal axis of the clamp and operable to accommodate a threaded element;
at least one cantilevered clamping member integrally connected to the clamp at a second end of the clamp and freely extending away from the clamp to operably create a clamping ramp angled with respect to the longitudinal axis; and
a sleeve slidably engageable with the clamp;
wherein in an installed position of the sleeve having the sleeve surrounding the clamping ramp, the sleeve is operable to deflect the clamping member such that the clamping member is elastically deformed into the cavity to engage the threaded element.
2. The threaded element engagement fastener of claim 1 , further comprising a flange integrally joined to the clamp and extending radially outward from the first end of the clamp, the clamping member extending freely away from the clamp and the flange, and the cavity extending through both the clamp and the flange.
3. The threaded element engagement fastener of claim 1 , further comprising at least one frangible element connecting the sleeve to the second end of the clamp in an initial state, the at least one frangible element being broken by an axial force acting on the sleeve operable to reposition the sleeve toward the installed position.
4. A method for engaging a threaded fastener with an engagement fastener, the engagement fastener having a tubular clamp, a flange integrally joined to the clamp having a plurality of apertures, a sleeve having a plurality of projections slidably engageable with the clamp, and a cavity created through both the clamp and the flange, the method comprising:
sliding the engagement fastener onto the threaded fastener;
applying an axial force to the sleeve to axially displace the sleeve onto the tubular clamp;
sliding the sleeve over the tubular clamp to deflect the clamp members into the cavity and into contact with the threads of the threaded fastener; and
engaging the projections of the sleeve into the apertures of the flange to prevent rotation of the sleeve relative to the flange.
5. The method of claim 4 , further comprising extending a latching finger from the sleeve.
6. The method of claim 5 , further comprising creating a catch on the latching finger.
7. The method of claim 6 , further comprising engaging the catch of the latching finger with the flange.
