INSTRUMENT HOUSING RETAINING MEMBER Filed Oct. 28, 1966 m I i I/zxw INVENTOE Z70 glam" Eye/2e )Qifdu'e ATTORNEYS United States Patent Office 3,3416% Patented Get. 1'7, 1967 3,347,608 INSTRUMENT HOUSING RETAINING MEMBER Douglas Eugene Ritchie, Chelmsford, Mass., assignor to Hewlett-Packard Company, Palo Alto, Calif., is crpo= ration of California Filed Oct. 28, 1966, Ser. No. 590,348 Claims. (Cl. 312-216) This invention relates to retaining strips, and more particularly, to an elastomeric retaining strip adapted to re tain sub-assembly panels within a housing.
Today many electronic instruments are housed in a cabinet having an open front end. Sub-assemblies used in the instrument are adapted to be individually or jointly slid into the instrument housing and locked. The locking means, typically screws or bolts, are adapted to be turned easily. Often the locking means is actuated by a thumb screw or the insertion of a coin, screwdriver or other article into a slotted screw head. Although generally satisfactory for this purpose, such means are relatively expensive not only to purchase but also to install in the cabinet. For each screw employed, a nut or socket into which the screw is threaded, must be attached to the housing. Also, if a number of sub-assemblies are employed within the housing, each must be individually locked.
Screws and bolts have another disadvantage. Often it is difficult to align the screw with its socket or receptacle. Also, if the operator twists too hard, he is liable to strip the threads off the screw, requiring a relatively expensive and time-consuming replacement or repair job.
It is therefore an object of this invention to obviate many of the disadvantages of the prior art means for retaining panels within a housing.
Another object of this invention is to provide an improved panel retaining assembly which is relatively cheap to construct.
An additional object of this invention is to provide an improved panel retaining means which facilitates the quick removal of sub-assembly panels from an instrument housing.
Still another object of this invention is to provide an improved instrument housing panel retaining means which is relatively secure and yet easily replaceable.
In accordance with a preferred embodiment of the invention there is provided a retaining assembly for the front panel of an instrument housing. The retaining assembly includes a longitudinally extending rigid strip secured to the front edge of the bottom panel of the housing. The rigid strip has an upwardly opening groove therein. A longitudinally extending piece of elastomeric material of uniform cross-section has inner and outer lips along its bottom edge defining a longitudinal groove therein. The inner lip is adapted to engage the groove of the rigid strip. In turn, the groove in the piece of elastomeric material is adapted to engage the outer lip of the rigid strip thereby locking the front panel within the housing. The elastomeric piece is easily removable and insertable to facilitate quick removal and replacement of the front panel.
The novel features that are considered characteristic of this invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of operation, as well as additional objects and advantages thereof, will best be understood from the following description when read in connection with the accompanying drawings, in which:
FIGURE 1 is a front perspective view of an instrument housing of the type with which this invention finds use;
FIGURE 2 is a partial perspective view of the retaining assembly prior to use; and
FIGURE 3 is a partial perspective view of the retaining assembly of this invention in its retaining position.
In the drawings there is seen an instrument cabinet or housing 19 of conventional construction. This instrument housing It) includes a bottom wall 12, top wall 14, side walls 16, and a back wall 18, preferably fabricated from appropriate sheet metal stock such as aluminum or stainless steel as may be desired. The sheet metal pieces, after being cut into size, may be fastened together as by screwing, welding, brazing, or other appropriate means to form a rectangular type housing. The side walls 16 of the housing may be provided with U-shaped handles and corner guards 20 to facilitate handling and also to strengthen the housing. The handles 20 may extend along the length of the sides at the top and bottom portions thereof and may be attached by screws or bolts to the housing 10.
On the interior portion of the walls 12, 14, and 18, a plurality of U-shaped grooved slides 22 are secured by appropriate means as by welding, brazing or screwing. These grooved slides 22 are adapted to receive the vertically disposed, sheet-like frame members 26 of one or a plurality of sub-assemblies 24 which are to be inserted into the housing 14. Other known slidable mounts may be employed as desired. These sub-assemblies 24 may be electronic amplifiers, modulators, meters, relays or other sub-components which are typically employed in instrumentation applications. Since the sub-assemblies 24 may be removed as by sliding them forward and hence out of the housing 10 and reinserted simply by properly aligning their vertical frame members 26 with the slides 22, a means must be provided for locking the sub-assemblies 24 in place so they do not slide forward and fall out of the housing 10.
In accordance with this invention, the sub-assemblies 24 are formed such that their front panel members 28 extend downwardly in the drawing below the bottom wall 12 of the housing 10. These front panel members 28 may be formed from suitable sheet stock. As may be seen more clearly in FIGS. 2 and 3, the front panels are retained by a retaining means which comprises two pieces; namely, rigid extruded strips 30 and elastomeric retaining strips 52. The extruded strips 30 may be formed by conventional extrusion processes from aluminum or other suitable material so as to have a relatively uniform crosssection. The strips 30 include a back-portion 32 which is secured as by welding, brazing, or other appropriate means to the bottom portion of the bottom wall 12 at the front portion thereof. The front portion of the extruded strip 30 extends downwardly so as to be offset slightly from the plane of the bottom wall 12. Extending upwardly from this offset portion 64 of the extruded strip 36, is a longitudinally disposed T-shaped member 36. This T-shaped member 36 has a cross-bar 38, the back edge of which abuts the front edge of the bottom wall 12 of the instrument housing 10. In this manner, the subassemblies 24 may be slid back along the slides 22 until the back face of the front panel 28 abuts the front edge of the cross bar 38. At the front of the offset portion 34, a longitudinal groove 42 is formed in the upper surface. This longitudinal groove 42 has an enlarged bottom portion which is defined by an elongated protuberance or lip 44 and the front side wall 46 being slanted inwardly approximately at a 15 angle with the vertical. The back side wall 48 of the groove 42 is subsantially vertically disposed up to the lip 44. The front edge 50 of the extruded strip 30 is arcuate, having its radius at the center of the lip 42.
Further in accordance with this invention, an elasto meric retaining strip 52 having a protuberance 56, shaped to substantially conform to the shape of the groove 42 3 in the extruded strip 30, is adapted to be squeezed or snapped into the groove 42. The retaining strip also has a groove 62 adapted to interlock with the tongue 47 formed by front wall 46- of groove 42 and arcuate portion 50 of the extruded strip 30.
The retaining strip 52 has a uniform cross section throughout its length. The material of the retaining strip 52 may be of any suitable elastomeric material such as rubber, synthetic rubber such as butadiene-styrene copolymers, butadiene-acrylonitrile copolyrners, polychloroprene, compatible mixtures of the above materials, plastic compounds such as certain of the vinyls, etc., the only requirements being that the materialis sufficiently springy and rubber-like so that it will be stretched so as to admit unimpeded movement of the material so as to form a satisfactory interlock, as will be described, with the extruded strip 30. Actually, any other material suitable for forming a locking engagement with the extruded strip 30 and for deforming portions thereof so as to provide a relatively tight retention may be employed. Strips of this character may be made by molding or extrusion or any other satisfactory production method and may be compounded so as to form any color combination desired.
The back edge 54 of the retaining strip 52 is slanted outwardly and upwardly at a 15 angle with respect to the vertical so as to be capable of being deformed when inserted, as seen in ,FIG. 3 at 55, so as to tightly press r the front panel member 28 against the front edge of the cross bar 38. The upper portion of the back edge 54 is oflset and extends outwardly or backwardly in the drawing slightly more than the lower portion so as to enhance this squeezing retention. A concave recess 58 in the back edge 54 of the retaining strip 52 is formed so as to provide an improved lock when the protuberance or tongue 56, defined by the recess 58 and groove 62, is introduced into the groove 42.0f the extruded strip 30. The tongue 56 is adapted to be squeezed or forcedinto the groove 42.
The front lip 60 of the retaining strip 52 together with the tongue 56 define a groove 62 which is substantially congruent in cross-section with the cross-section of the tongue 47 of the extruded strip 30. The front edge 64 of the groove 62 is thus seen to be arcuate to complement the curvature of the front edge 50 of the extruded strip 39, and the back edge 66 of the groove 62 is slanted so as to complement the slanted front edge 46 of the groove 42.,
To employ the retaining assembly of this invention, the sub-assemblies 24 are slid into the housing such that their front panels 28 each abut thefront edge of the cross-bar 38 of the extruded strip .30. Next, the retaining strip 52 is installed by inserting the tongue 56 over and into the groove 42 and pressing downwardly and inwardly until the tongue 56 is brought in overlying relation with groove 42 and the protuberance or tongue 47 is in underlying relation with the groove 62, where upon the final application of pressure along the length of the retaining strip 52 drives the strip into position and the inclined or wedged face 54 of the retaining strip presses against the front panel 28. The resulting wedging action of the face 54 produces a clamping or gripping and tightly holds the sub-assemblies within the housing.
To remove this retaining strip, it is merely necessary, as by prying with a sharp object such as a screwdriver or other device at hand, to loosen one end of the retaining strip 52 and withdraw the strip successively along its length as by peeling it from the interlocking relationship of the tongue 56 with the groove 42 and the tongue 47 with the groove 62..
While this invention is described in connection with an instrument housing, it should be apparent that it may find other panel retaining uses as well, such as the retaining of a pane of glass within a Window frame. If desired, a locking strip similar to extruded strip 30 may be employed along the upper surface of the housing It It will be obvious that various modifications may be made in the apparatus and the manner of operating it. It is intended to cover such modifications and changes as would occur to those skilled in the art, as far as the following claims permit and as far as consistent with the state of the prior art.
