Definitions

  • the invention relates to a housing with two housing parts that can be opened, one of which is used to attach at least one tool holder.
  • Such housings are generally known. For example, they are available as cartridges for twist drill sets, tap sets, screw extractor sets, and the like.
  • the tool holder is adapted to the tools or tool sets to be held.
  • each tool holder has different insertion openings, holding clips or the like in order to be able to securely hold and hold the respective tool.
  • cassettes A disadvantage of these housings, which are also referred to below as cassettes, is the lack of compatibility between the tool holders and the housing parts. For this reason, a separate cassette is required for tool holders for holding tools of different dimensions and sizes.
  • such a housing is the subject of German utility model G 90 13 289.0.
  • a tool holder is integrated in the lid and the interior division of the cassette is tailored to the specific application, so that in principle the above also applies.
  • the object of the invention is to develop the housing so that it can be assembled in a very simple manner with reduced storage costs.
  • the advantage of the invention is that, with minimal tool costs, only a multiplicity of different tool holders are required for use in one and the same cassette.
  • the tool holder alone is adapted to the tools to be accommodated in each case.
  • all different tool holders each have suitably designed fastening points which are assigned to the predetermined fastening points of the housing part.
  • the attachment points on the different tool holders can be different as required.
  • the cassette must have all possible attachment points for the different tool holders.
  • the tool holder with a tight fit is essentially free of play in its housing part sits, and that this measure is combined with a snap-in connection between the tool holder and the housing part.
  • a particularly advantageous embodiment provides that the snap-in connection should also be releasable.
  • the additional advantage of easy interchangeability for example in the event of damage.
  • the development according to claim 4 offers the advantage that the inserted tools can be made easily accessible in the tool holder.
  • the tools can also be e.g. present very well for sales purposes.
  • the development according to claim 5 offers the advantage that the pivoting movement takes place automatically.
  • the tool holder opens in relation to the opened housing part in such a way that the inserted tools can easily be gripped behind with the fingers without bumping against the housing part.
  • This training is particularly suitable for drills of all kinds.
  • the development according to claim 6 offers the advantage that an unintentional loosening of the locking connection is omitted, since the lock counteracts.
  • the lock resiliently against the locking connection, so that the locking connection can only be released after bending the lock.
  • the lock can consist, for example, of an elastically deformable securing web which is movable in the spring direction and in the direction perpendicular thereto, which coincides with the latching direction is rigid. Only after the safety bar has been bent away can the latching connection be released in the direction of the loose movement. Exemplary embodiments are given for this.
  • the development according to claim 8 offers high strength for the tool holder.
  • the development according to claim 9 offers the advantage that no further components are required to limit the tool holder in its pivoting movement. It is known in this connection to articulate the tool holder for the pivoting movement, for example by means of parallel guides or coupling members, on one of the housing parts, so that the pivoting movement is predetermined or limited by the length of the parallel guide or the geometric arrangement of the coupling members. However, this involves an additional assembly effort, which the invention avoids in the development according to claim 9.
  • a housing is formed, which can not only be assembled in a very simple manner with reduced storage effort, but also has increased stability and torsional rigidity.
  • the defined end position reliably prevents the hinge axis from being overloaded as a result of excessive force application, since the rotation guide allows a clearly noticeable path limitation when the housing parts are opened.
  • Another advantage lies in the fact that no further components are required than the two housing parts, possibly supplemented by the corresponding number of tool holders.
  • the assembly of the housing according to the invention therefore does not require any additional effort and this with increased stability, in particular in the open position.
  • the development according to claim 16 offers the advantage that unintentional closing of the housing is avoided.
  • the development according to claim 17 also offers the advantage of a large locking force when the housing is closed, since the latching position in the closed position is preferably achieved when the two housing parts lie flush with one another.
  • this locking position can be combined in the closed position with a locking tab on one of the housing parts, which, in the manner of a pretensioned case, locks in a known manner in a corresponding device of the other housing part.
  • the development according to claim 18 offers the advantage of further improving stability. An unintentional tilting or falling over of the opened housing can be reliably prevented. It should be expressly pointed out that in a preferred further development it is provided that the two opened housing parts only have two mutually perpendicular and smoothly continuous outer surfaces, one of which rests on the substrate, while the other is supposed to be approximately perpendicular to the substrate.
  • the development according to claim 19 can be carried out in particular on plastic housings which can be produced in large numbers with simple means.
  • This development therefore offers the advantage that a pair of housing parts that always match one another can be produced in large quantities using only a single negative mold.
  • the locking positions can be given by wall openings.
  • the advantage can be achieved that clogging of the recess with dirt cannot be considered, since any dirt accumulated can always be pushed through the wall openings into the open by the latching pins.
  • the figures show a hinged housing 1 with two housing parts 3, 4 connected via a hinge axis.
  • the housing parts are a housing base 3 and a housing cover 4.
  • a cassette is formed for receiving a tool in at least one separate tool holder.
  • the housing cover 3 is used to attach two tool holders 5, 6.
  • each tool holder 5, 6 is a component that is independent of the housing parts 3, 4.
  • Each tool holder is detachably attached to its housing part 3 by means of a snap-in connection 7.
  • each tool holder 5, 6 with a tight fit 8 is seated in its housing part 3 essentially without play.
  • the snap-in connection here consists of two stub-like short hinge pins 9, which each project outwards from the side flanks of the tool holder 5, 6, and which are inserted into two associated pin holes 10.
  • the hinge connection enables the tool holder 5, 6 to pivot in the housing part 3. It can be advantageous if the tool holder 5, 6 is arranged in the cover of the housing part 3. In this case, the hinge connection fully complies with the folding movement 12 of the cover. On the other hand, the hinge connection enables the tool holder 5, 6 to make a limited pivoting movement in the opposite direction. Seen overall, the tool holder 5, 6 consequently makes a pivoting movement 11 which remains somewhat behind the opening movement 12 of the cover 3.
  • the tool holder 5 has freely movable spring tongues 13 at its lower end, which are a continuation of the side walls of the tool holder 5.
  • each of the spring tongues 13 can be freely pressed in the direction of the other spring tongue as soon as the securing web, which will be discussed further, has been bent out of the area between the spring tongues 13.
  • a snap-in connection 7 was created in this way, which enables a pivoting movement 11 of the tool holder 5,6 in the manner of a hinge, which remains somewhat behind the opening movement 12 of the housing 3.
  • FIG. 6 also shows how such a snap-in connection is secured against loosening.
  • the hinge pins 9 are arranged on two mutually parallel, elastically deformable spring tongues 13 which can be pressed together in order to be able to insert the hinge pins 9 into the pin holes 10 when they are pressed together.
  • a locking element 14 is arranged between the two spring tongues 13, which rests on the inside of the spring tongues 13.
  • the width of the locking element corresponds essentially exactly to the distance between the inner surfaces of the two spring tongues 13.
  • the locking element 14 is the lower continuation of the transverse wall 30, which forms the rear wall of the tool holder 5 in its remaining area.
  • the connection of the rear wall to the two side cheeks of the tool holder 5 in the area of the locking element 14 is interrupted and the rear wall is bent inwards, so that a crosspiece is formed which prevents the two spring tongues 13 from being pressed together unintentionally (see double arrow).
  • the locking element 14 is made of elastic material and can be bent out of the spring area of the spring tongues 13 with a handle (see arrow). In this case, the spring tongues spring freely against each other and make the snap-in connection.
  • the entire housing consists of only two parts plus the number of tool holders 5, 6 provided. Separate fasteners such as Screws, rivets and coupling links to limit the swiveling movement are therefore no longer required.
  • the locking connection 7 takes place at predetermined fastening points which are provided on the housing parts. In this way, any number of different tool holders 5, 6 can be accommodated in a single housing. This has the advantage that a standardization in terms of the housing can take place and that only the tool holders 5, 6 need to be adapted to the respective tool.
  • each tool holder 5, 6 is essentially limited in its pivoting range by stop 15 on its housing part 3.
  • each tool holder has which on its area below the pivot axis 23 approaches the housing wall during the opening movement 12, a withdrawn bevel.
  • the bevel goes over the rear side of the tool holder including the two spring tongues 13 and tapers from the area of the hinge connection to the lower end of the tool holder, where the spring tongue is given its narrowest width.
  • the tool holder is attached to the cover of the housing (3) and the pivot axis 23 is arranged in the lower region of the tool holder 5, 6.
  • the pivot axis 23 is arranged in the lower region of the tool holder 5, 6.
  • each tool holder 5, 6 executes a free gaping movement, which is only limited by the stop 15.
  • the stop 15 is formed by the inner cover wall 21 and the rear wall of the tool holder 5, 6. If the tool holder 5, 6 were attached in the housing base 4, the stop 15 would be formed by the inner bottom wall 22 and the facing area of the tool holder 5, 6.
  • the pivot axis 23 is arranged in the lower region 24 of the tool holder 5, 6 and at a distance 25 from the stop 15. Furthermore, the region 26 pivoting in the direction of the stop 15 must have the bevel withdrawn in order to enable the gaping movement on the one hand and to limit it on the other hand. Accordingly, the withdrawn bevel has a double function.
  • All housing parts and the tool holder (s) are advantageously made of a plastic.
  • Fig. 2 also shows that, -here-, the housing cover 3 at the end of two opposing end walls 27, 28 which together with the housing wall bent to this end form a groove-like throat 29 (see Fig. 3.4) .
  • the housing cover 3 and the housing base 4 have a projection 31 and an associated recess 32 which are adapted to one another.
  • the projection 31 snaps into the associated recess 32, so that there is a certain degree of security against inadvertent closing.
  • the tool holding devices are adapted to the tool diameter.
  • webs remain which slightly reduce the diameter of the tool holding devices.
  • the webs are so small that they allow an elastic movement of the tool holder, which is in the order of magnitude of their own dimensions, under elastic deformation. The tool is then radially clamped in the tool holder and secured against falling out.
  • the tool holder 5 is inserted with its first hinge pin 9 into the pin hole 10 of the cover 3 pointing backwards. Thereafter, the two parts are further braced against one another in the same direction, as far as necessary to insert the opposite hinge pin of the same tool holder into its associated hinge hole 10. This would complete the assembly of the first tool holder 5 and the assembly of the second tool holder can be carried out in the same way.
  • the bottom 4 is connected to the lid 3 in that the inwardly pointing pins of the bottom 4 are inserted into the associated holes in the lid 3 while bending the free ends of the bottom 4 apart and the housing is fully assembled and can be fitted.
  • Figure 8 shows a housing 1 with two housing parts 3, 4 that can be opened.
  • One of the housing parts forms the housing cover 3, while the other housing part forms the housing base 4.
  • Both housing parts 3, 4 are connected to one another via the common hinge axis 2.
  • the hinge axis is formed by a facing pair of pins 45, which is arranged on two spring tongues of the one housing part. As the arrow on the dash-dotted line shows, this pair of pins snaps into a corresponding pair of bores 46 in the other housing part a, whereby the hinge axis is fixed between the housing parts 3, 4.
  • the housing cover 3 has a width which is essentially fitted exactly between the free spring tongues 44 of the housing base 4, so that the housing cover 3 is laterally guided within the housing base 4 between the spring tongues 44 in the area of the hinge axis 2. As can be imagined, there should be essentially play-free contact between the two housing parts in the area of the lateral guide.
  • a rotary guide consisting of a sliding block 40 and a sliding track 41 is now provided in the present case between the laterally leading regions of the housing parts (3, 4).
  • the sliding block 40 is arranged on the housing cover and the sliding block 41 on the housing base 4 without restricting the invention.
  • the leading areas of the housing parts on both sides of the housing have such a rotary guide.
  • the slide track 41 runs exactly concentrically to the center of the hinge axis 2 on a circular path, so that in addition to the contact between the lateral surfaces of the hinge pins 45 and the associated bores 46, a pair of sliding surfaces is formed between the curved surfaces of the concentric slide track 41 and the lateral surfaces of the sliding block 40 .
  • snap-in positions 42, 43 are provided at the ends of the respective slide tracks.
  • the latching positions 42, 43 span an angle of approximately 90 degrees, the apex of which coincides with the hinge axis 2.
  • the two housing parts can be opened and closed relative to one another by approximately 90 degrees.
  • the distance between the hinge axis 2 and the rear side 47 of the housing cover 3 is essentially the same as for the downward-facing bearing surface 49 of the housing base 4.
  • the rear side 47 thus forms a downward-facing surface of the housing cover 3.
  • the distance measurement just specified can therefore be achieved with simple means that the underside 49 of the housing base 4 and the rear side 47 of the housing cover 3 lie in exactly one single level in the unfolded position and in this one level completely on the base, for. B. a workbench.
  • the continuous contact surface formed in this way offers the advantage of additional tilting stability which, in combination with the latching position 42 in the opened position, forms an overall very stable housing.
  • the opening force must namely overcome the latching force of the latching position 43 in the closed position even if the elastic bias of the latch 48, with which it engages behind a corresponding retaining projection 50, is made ineffective by lifting it off with the thumb.
  • the slide track 41 is attached as a circular groove in a housing wall, the groove depth of which is less than the thickness of the housing wall. Starting from the bottom of the groove, there remains a residual wall thickness that is conducive to stability.
  • this offers the possibility of designing the latching positions 42, 43 as through bores in the housing wall, into which the sliding block 40 can latch in the respective open position or closed position. This is achieved in that the effective length of the sliding block 40 is somewhat greater than the depth of the groove, so that this rests with its end face under prestress on the groove base and runs in the course of the sliding track under elastic pressure in the axial direction of the hinge axis 2 in the rotary guide .
  • the cross-sectional dimensions of the sliding block 40 are matched to the groove width of the sliding track 41 with a clearance fit.
