Description
June 19, 1962 C. H. KOCH, JR., ETAL HOLDING MECHANISM Filed Sept. 16, 1959 United States Patent 3,93%,338 Patented June 19, 1962 Fire 3,039,838 HOLDING MECHANISM Charles H. Koch, Jr., Glenside, and Robert Binns, Southampton, Pa, assignors to Industrial Corporation, a corporation of New York Filed Sept. 16, 1959, Ser. No. 840,436 9 Claims. (Cl. 312-335) This invention relates to apparatus for releasably locking two parts which are arranged to be slidable relative to one another.
The invention as disclosed herein is shown as embodied in a telescoping type drawer slide. However, it will be apparent that the invention is adaptable for use in other analogous organizations.
In one aspect the invention contemplates detent means to releasably lock a pair of relatively movable parts including a pair of arcuately-shaped, strip-like members made of resilient material mounted on one part and forming a channel for accepting a tab on the other part, the tab, when in the channel, expanding the same and the ends of the strips being confined in the direction of channel expansion but free to expand in a direction normal thereto so as to permit but resist expansion and thereby exert a force to hold the tab in the channel.
In another aspect the invention contemplates detent means to releasably lock a pair of relatively movable parts including a pair of generally arcuately-shaped, strip-like elements made of resilient material and mounted on one part in a manner to form an expansible channel, the expansion of the channel being efiected by a tab on the other of the parts entering the channel and the expansion of the channel being resisted by virtue of the strips being confined so that the shape thereof becomes less arcuate and exerts a force for holding the tab in the channel.
In still another aspect the invention contemplates a detent device formed with elongated strip-like elements disposed adjacent one another and forming a flared channel for receiving a tab for expanding the channel and the outer portion of each element forming leaf-like springs, the ends or" which are adapted to be confined to cause the elements to permit but resist channel expansion to produce a force for holding the tab in the channel.
In still another aspect the invention contemplates a detent spring which has two interconnected side pieces forming a channel adapted to be expanded by a detent tab entering the same together with leaf-like spring elements secured to the side pieces for use in resisting channel ex pansion so as to provide a force for holding the tab in the channel.
A preferred construction or the invention will be apparent from the following description and drawings wherein:
FIGURE 1 is an isometric View showing the invention embodied in a typical telescoping-type drawer slide;
FIGURE 2 is a fragmentary plan view illustrating the detent spring and tab;
FIGURE 3 is a view similar to FIGURE 1 showing the tab and spring in the holding position;
FIGURE 4 is a sectional view taken along the lines 4-4 of FIGURE 3;
FIGURE 5 is an enlarged isometric view of the preferred construction of the detent spring;
FIGURE 6 is an enlarged fragmentary isometric view of a modified spring and tab, the elements being shown in the closed position.
In FIGURE 1 we have shown apparatus for mounting two relatively movable parts, the apparatus taking the form of a pair of telescope-type drawer slides 1 and 2. The slides are interconnected by an elongated bearing race 3 which permits the slides to be relatively movable.
When used for supporting a drawer or the like an arrangement such as shown is used on each side of the drawer with the slide 2 being attached to the frame or cabinet and the slide 1 being attached to the drawer per se. To define the extremities of motion of the slide 1, the slide 2 is provided with tabs 4 and 5, the tab 4 being engaged by the race when the slide 2 is moved all the way to the left and the tab 5 being engaged by the opposite edge of the race when the slide 1 is moved all the way to the right. Except for certain portions of the tab 5 which will be explained later, the above-mentioned elements are all of standard construction.
For preventing relative motion or releasably locking the two slides when the slide 1 is moved, say all the way to the left, we have provided a detent spring 6 which is adapted to be engaged by the part 10 of the tab 5.
A preferred construction of the detent spring is shown in FIGURE 5 wherein it will be seen that the spring comprises a pair of elongated strip-like elements 11 and 12 which are generally arcuate in shape. The elements are disposed so as to form a channel 14, the axis of which is generally indicated by A. The strips 11 and 12 have slots 15 and 16 which extend generally in the direction of the axis A. The two strips are interconnected by a bridge member 29 which has an aperture 21 by means of which the spring is connected to the part with which it is used. It will be noted that the slots 15 and 16 are spaced from the bridge 2! It will be apparent that the two strips 11 and 12 are identical in construction and are mirror images of each other. Considering the details of construction of each strip, it will be seen that the strip 11 has a side section 22 and the strip 12 a side section 23. The two side sections extend upwardly from the bottom or bridge 26. The side section 22 has a pair of end sections 24 and 25 respectively connected to the op posi-te edges of the side section and extending angularly outwardly from the axis of the channel. The side section 23 has a pair of end sections 26 and 27 which also extend angularly outwardly from the axis of the channel. It will be observed that the slots 15 and 1d extend wholly through their respective side sections and substantially into the respective end sections. When the detent spring is mounted in the slide 1, the edges e are engaged with the sides 28 and 29 of the slide.
The term arcuate as describing the shape of the strips 11 and 12 is used in the generic sense in that it is intended to apply to a shape which is defined as a part of a circle and to a strip of the shape such as shown in FIGURE 2. Further, it should be observed that the term channel as used herein contemplates that the channel be formed wholly by the side pieces 22 and 23 with the end pieces 24, 25, 26 and 27 operating to permit but resist channel expansion. Preferably, however, the channel comprises the end pieces 22 and 23 together with portions of the edge pieces adjacent the end pieces so that the channel in effect has flaredends. This makes for easy entry and exit of the tab.
Also, it is pointed out that the preferred form of detent spring contemplates two end sections. However, in certain instances one pair of end sections may be eliminated. In such instances the detent spring may have the same form as shown in FIGURE 5 but with the ends 24 and 26 removed and the slots 15 and 16 extending only partially through the sides 22 and 23.
Referring to FIGURE 2 it will be seen that the part 10 of the tab 5 is larger than the width of the channel 14. Thus, when the parts are in the position as shown in FIGURE 3, the tab has expanded the channel or moved the sides 22 and 23 outwardly or away from the axis A. From a comparison of FIGURES 2 and 3 it will be seen that the shape of the strips in FIGURE 3 is somewhat less arcuate than the shape shown in FIGURE 2. This is due to the fact that the edges 6 are confined (by the sides 28 and 29) against movement in a direction the same as the direction of channel expansion but are free to move normal thereto or along the axis A. The end sctions 24, 25, 26 and 27 being made of resilient material, act in the nature of leaf springs and tend to resist the outward movement of the side sections 22 and 23 or resist channel expansion. Thus a force is developed by the side sections 22 and 23 which is exerted on the tab and acts to hold the tab within the channel so that the slides 1 and 2 are held immovable. From an inspection of FIGURE 4 it will be seen that the tab 10 engages the sides *22 and 23 at a point just above the slots and 16.
in FIGURE 6 we have shown a detent spring which is identical in construction to the detent sprin just described except for the absence of slots such as slots 15 and 16. Also, it will be noted in FIGURE 6 that the tab 31 is of different construction than the tab 10, being a generally rectangular piece oriented normal to the sides and bridge.
The tab 19 in plan is generally circular or disk-like in shape and it will be observed that the tab is oriented so that it is generally parallel to the bottom or bridge member 29. This form of the tab is preferred because the area of metal of the tab in contact with the detent spring is held to a minimum and this is desirable from a standpoint of permitting lon er spring life. Furthermore, the construction and orientation of the tab 10 is such that it practically eliminates the possibility of the tab engaging or hanging up on the edges e of the spring. Such contact or hang-up is undesirable because the same may tend to rip the spring out of its mount. Where greater holding area is desired, however, a construction as shown in FIGURE 6 may be employed.
V is indicated by the dotted lines 32 in FIGURE 5.
The form of the detent spring shown in FIGURE 5, i.e., with slots 15 and 16, is preferred because it greatly enhances spring life. We have found that with this construction the greater portion of the change in shape of the spring from arcuate toward planar) takes place in the area above the slots. This, of course, has the effect of reducing bending strains atthe joinder area between the bridge and sides 22 and 23.
