Posnack [57] ABSTRACT A support device for detachable connection to two adjacent holes in a pegboard or other perforated panel. A hollow casing of dished-in configuration has extending from the front wall thereof a support rod the rear end of which extends through said front wall and is bent upwardly. Two laterally opposite clamping members with overlapping wings extend through an upper horizontally disposed slotted portion in the casing and are pivotally mounted over said upwardly bent rod, said members having front arms adapted for manual grasping, and rear arms with hooked portions adapted for insertion through two adjacent holes in the pegboard and for holding engagement with the rear surface of the pegboard. The respective clamping members have notched portions the respective opposite sides of each of which straddle the adjacent sides of said slotted portion and are engageable therewith to limit the pivotal movement of said clamping members between two limiting positions. At one of said positions the said hooked portions are spaced apart a predetermined distance, which is equal to the spacing between two adjacent holes in the pegboard, the other of said positions determining the holding positions of the said hooked arms. Spring means are provided to normally yieldably urge said hooked members into their operative holding positions.

9 Claims, 5 Drawing Figures DETACI-IABLE SUPPORT DEVICE FOR PEGBOARDS BACKGROUND OF THE INVENTION 1. The Field of the Invention This invention relates to detachable support devices, and is particularly directed to devices for supporting display articles and shelves and which are adapted for detachable connection to perforated panels such as pegboards.

2. The Known Art The most commonly used pegboard supports of the above mentioned category comprise single rods the forward portions of which are adapted to support an article, the rear portions being bent for insertion through and positioning behind a pegboard aperture. These devices have the disadvantages of not being rigidly secured in place, not providing a firm support, and of being subject to inadvertent detachment. The known two-hole pegboard attachments, that is, those having means for connection to two adjacent apertured portions of the panel, are relatively complex and costly and have certain shortcomings which do not render them suitable for display pegboard uses. Among the latter category of pegboard supports are those which comprise a number of separate components that must be assembled before each use, those which require careful manual manipulation and spacing adjustment for properly engaging the spaced apertured portions thereby entailing loss of time and frequently resulting in the mutilation of the pegboard in the region of the holes, and those that require considerable effort and manual dexterity for their removal from the panel.

OBJECTS OF THE INVENTION It is the objective of this invention to provide a pegboard support of the above-mentioned category having none of the aforesaid shortcomings. Specifically, among the objects of this invention are the provision of means that will readily enable the device to be attached to two adjacent pegboard apertures with a minimum of manipulation, that will enable the device to be readily detached from the panel with little effort, that will securely maintain its position on the pegboard without displacement, that is of unitary construction requiring no assembling of components, and that can be readily fabricated at a relatively low cost.

Other objects, features and advantages will appear from the drawings and the description hereafter given.

SUMMARY OF THE INVENTION In the preferred form of this invention a support rod is firmly attached to the front plate of a dished-in casing defined peripheral wall the rear peripheral edge of which is adapted for engagement with the front surface of a pegboard panel, the forward portion of said rod being adapted to support an article in known manner. The said front plate of the casing contains at the upper portion through a horizontally disposed slot through which extend two pivotally mounted clamping members, said members having respective laterally opposite front arms and rear arms, the front arms being adapted for manual grasping and the rear arms being adapted for insertion through two adjacent holes of the pegboard, the rearmost terminals of said rear arms being hooked for holding engagement with the rear surface of said pegboard. Said clamping members contain two inwardly extending overlapping wings with congruent holes through which extends a pivot pin. In the preferred embodiment illustrated, the said pivot pin is a rear upwardly bent continuation of the suppo t rod affixed to the rear surface of the front plate of the casing. A spring is mounted over said pivot pin and is coactively connected to both of said front arms to yieldably urge them outwardly in opposite directions so that the rear hooked portions are urged inwardly towards each other into closer positions and normally yieldably maintained in their operative holding positions.

The said clamping members contain at their laterally opposite outer edges respective notched portions, interengaged with the respective adjacent laterally opposite margins of said LII ' ing positions the said hooked portions are in their operative holding positions in engagement with the rear surface of the panel. Thus by a squeezing manipulation of both of the front arms the device is in position for insertion into or removal from the pegboard; and upon a release of said front arms the inserted hooked portions are yieldably urged into their projected holding positions.

DESCRIPTION OF PREFERRED EMBODIMENT In the illustrated embodiment of this invention the casing 10 is of dished-in configuration being defined by the peripheral wall 111 surrounding the front plate 12, the rear of the casing 10 being open. The rearmost edge 13 of said peripheral wall is in one plane, whereby it is adapted for engagement with the front surface 14 of the perforated panel or pegboard 15, said pegboard being of conventional construction and having therein a plurality of equally spaced holes 16. Attached to and extending forwardly from the said front wall 12 of the casing is the support rod 17 for supporting a display article in known manner.

The plate 12 contains near the top thereof the horizontally disposed slotted portion 18 through which extend the two pivotally mounted

clamping members

19 and 20. Said clamping member 19 comprises the front arm 21, the rear arm 22 and the inwardly extending wing 23; and the said member 20 comprises the front arm 24, the rear arm 25 and the inwardly extending wing 26. The said wings are in overlapping engagement and have therein the

respective holes

27 and 28 which are in congruent relation. Extending upwardly through said two

holes

27 and 28 is the pivot pin 29, the arrangement being such that the said

clamping members

19 and 20 are pivotally mounted over said pin. In the preferred form illustrated said support 17 extends rearwardly through the hole 12a in plate 12, the rearmost portion being bent upwardly at right angles thereby constituting the said pivot pin 29. The particular construction shown in the drawings indicates a forwardly grooved portion 30 in plate 12 accommodating at least a portion of said pivot pin 29, the latter being welded or otherwise affixed to the rear of said plate 12.

Mounted above said clamping

members

19 and 20 and in engagement with the uppermost terminal portion 31 of said pivot pin 29 is the spring 32, said spring having forwardly and outwardly extending

arms

33 and 34 in engagement with said respective

front arms

21 and 24 to urge them outwardly into the operative projected positions. The said

rear arms

22 and 25 of said clamping members contain the

respective hook elements

22a and 25a, these being adapted to engage the rear surface 28 of said pegboard 15 when said

forward arms

21 and 24 are in their said projected positions at which they are yieldably maintained by the said spring 32.

The said front arm 21 contains the notched portion 35 and the said front arm 24 contains the notched portion 36, each of said notched portions extending inwardly from the respective

outer edges

21a and 24a of said respective front arms. Said notched portions 35 and 36 are interengaged with the respective laterally

opposite margins

37 and 38 of the said slotted portion 18, so that the pair of sides forming each of said respective notches are positioned for alternate engagement with the said

adjacent margins

37 and 38 of the slot 18. More specifically, the pair of

sides

39 and 40 of notch 35 straddle and are engageable with the margin 37 of the said slotted portion 18, and the pair of sides 42 and 43 of the notch 36 straddle and are engageable with the margin 38 of said slotted por tion 18.

The said respective sides 40 and 43 of the respective notches 35 and 36 are so positioned with respect to the plate 12 that they will engage the respective

marginal portions

37 and 38 when the said hooked

portions

22a and 250 are spaced apart a distance corresponding substantially to the distance between adjacent pegboard apertures 16; and the sides 39 and 42 are so positioned with respect to said plate 12 that they are in engagement with the said

respective portions

37 and 38 when said hooked

portions

22a and 25a are closer together, that is, in their projected holding positions at which said hooked portions are in engagement with the rear surface 28 of the pegboard 15.

In the operative use of this device, prior to its operative attachment to the pegboard 15 the said

arms

21 and 24 are manually pressed inwardly towards each other until the said sides 40 and 43 are brought into engagement with the said

marg'nal portions

37 and 38 of the slotted plate 12. The clamping

members

19 and 20 are now at their retracted positions, one of their two limiting positions. In this position the

rear arms

22 and 25 can readily be inserted through the two adjacent holes 16a and 16b, (see FIG. 2), the said rear arms being proportioned for longitudinal movement through said holes and the distance between said hooked

portions

22a and 25a being now substantially equal to the distance between the holes 16a and 1612. After the

rear arms

22 and 25 are operatively in place, the

front arms

21 and 24 are released, whereby the

arms

33 and 34 of the spring 32 yieldably urge said arms outwardly, the consequent pivotal action of said clamping

members

19 and 20 urging said

rear arms

22 and 25 into their projected holding positions (see FIG. 3).

The hooked portions 220 and 250 are so positioned with respect to the said peripheral edge 13 of the casing that when said hooked portions are in operative engagement with the rear surface 28 of the pegboard the said peripheral edge 13 will be in flat engagement with the front surface of the pegboard 15. In this position the entire device is firmly maintained in place, without any possibility of displacement from its rigid holding position.

It is especially noteworthy that inasmuch as said notched portions 35 and 36 determine the proper predetermined limiting positions of the hooked portions 220 and 25a, the abovedescribed manual manipulation of said

forward arms

21 and 24 enable the entire device to be quickly and accurately secured in place without any danger of mutilating the portions of the panel adjacent to the holes, and also enables the entire device to be quickly removed with a minimum of effort.

In the above description, the invention has been disclosed merely by way of example and in preferred manner; but obviously many variations and modifications may be made therein. It is to be understood, therefore, that the invention is not limited to any particular form or manner of practicing same.
