Abstract

The frame comprises separate frame members joined together to form a rectangular structure for receiving a display device such as a placard. A bracket having a pair of legs forming a right angle is provided at each corner of the frame to secure the frame members together. Each frame member has a pair of oppositely disposed, longitudinally extending grooves on the rear side which receive the legs of the brackets. A screw is provided on each leg of the brackets. Each screw has an enlarged head which clamps against a lip portion on the frame members to fasten the brackets to the frame. The upper frame member is utilized to mount the adjustable hanging clip. The adjustable hanging clip has upwardly and downwardly extending projections. The downwardly extending projection is received in the lower groove. The upwardly extending projection is depressible downwardly for insertion into the upper groove. A hanger structure is provided on the clip and is spaced rearwardly from the projections so that it will not have to extend above the frame. The positionment of the hanger member results in a lever action from the point of securement of the hanger structure to the frame resulting in the frame tending to rotate towards the support structure on which the hanger is secured. This prevents stress being applied to the depressible upwardly extending projection. The clip is slidable along the frame member to permit centering.

A bracket having a pair of legs forming a right angle is provided at each corner of the frame to secure the frame members together. Each frame member has a pair of oppositely disposed, longitudinally extending grooves on the rear side which receive the legs of the brackets. A screw is provided on each leg of the brackets. Each screw has an enlarged head which clamps against a lip portion on the frame members to fasten the brackets to the frame.

The upper frame member is utilized to mount the adjustable hanging clip. The adjustable hanging clip has upwardly and downwardly extending projections. The downwardly extending projection is received in the lower groove. The upwardly extending projection is depressible downwardly for insertion into the upper groove. A hanger structure is provided on the clip and is spaced rearwardly from the projections so that it will not have to extend above the frame. The positionment of the hanger member results in a lever action from the point of securement of the hanger structure to the frame resulting in the frame tending to rotate towards the support structure on which the hanger is secured. This prevents stress being applied to the depressible upwardly extending projection. The clip is slidable along the frame member to permit centering.

INVENTOR DAVID U. HILLSTROM ATTORNEYS DISPLAY FRAME HAVING ADJUSTABLE HANGING CLIP BACKGROUND OF THE INVENTION The device of the present invention is particularly useful in retail merchandising as a point-ofpurchase display. It is desirable in this field to provide framing devices which may be sold in the knockdown condition and readily assembled at the point of use. Further, it is desired that such devices be relatively inexpensive. The hanging of such frames has also been a problem. The usual picture frame wire is somewhat awkward to use and additionally will not permit mounting of the frame on a relatively narrow horizontal support element. The present invention provides a frame structure and an adjustable hanging clip which satisfy the aforementioned characteristics and which is eminently suitable for modern marketing techniques.

SUMMARY OF THE INVENTION The frame comprises separate frame members which are secured together to form a rectangular structure. The comers of each of these frame members are mitered so that the junctures thereof form a right angle. Oppositely disposed grooves are provided on the rear portion of 'each frame member. A right-angle bracket is provided on each comer. The legs of the bracket extend into adjacent grooves ofthe frame member. A threaded fastener having an enlarged head is received in each leg. The enlarged head clampingly engages lip structure defining the grooves to secure the frame members together.

The adjustable clip includes a base structure which has, on the forward end thereof, downwardly projecting structure for receptjon in the lower groove of the top frame member. First upwardly projecting structure is provided on the base and spaced rearwardly from the downwardly projecting structure. A flexible arm extends laterally from the first upwardly projecting structure. The flexible arm terminates in a free end. Second upwardly projecting structure is provided on the free end of the arm. The second upwardly projecting structure is spaced forwardly of the first upwardly'projecting structure and is received in the upper groove on the top frame member.

' The clip is mounted in the frame, by inserting the downwardly projecting structure into its groove and then depressing the arm. The second upwardly projecting structure is then placed in alignment with the other groove and the arm is released whereupon the second upwardly projecting structure is received in its groove. 7

An upwardly projecting hanger structure is provided on the base rearwardly of the first upwardly projecting structure. The hanger structure has a surface area sufficient to prevent tilting of the frame when it is hung on a support element.

FIG. 3 is a sectional view taken substantially along the line 3-3 of FIG. 1 looking in the direction of the arrows.

FIG. 4 is a plan view of a portion of the rear of the frame illustrating the adjustable hanger member. I

FIG. 5 is a front elevational view of the adjustable hanger member.

FIG. 6 is a side elevational view of the adjustable hanger member.

FIG. 7 is a sectional view taken substantially along the line 7-7 looking in the direction of the arrows.

FIG. 8 is a sectional view of the top frame member with an adjustable hanger member shown in dash lines illustrating the method of installment of the adjustable hanger.

Referring to the drawing, the frame structure 10, illustrated in FIGS. 1-4, will first be described. The frame has a conventional rectangular shape consisting of a pair of side members and a top and bottom member. The upper portion only of the frame is illustrated in FIG. 1. The lower portion is substantially identical, the lower frame having a cross-sectional configuration identical with the side frame members.

As will be noted, the ends of the side frame members 12, I4 and top frame member 16 are mitered at an angle of 45 so that the junctures of the frame members form a right angle. As shown in FIGS. 2 and 3, the top frame member 16 has a crosssectional configuration comprising a horizontally extending sidewall 18 from which depends a downwardly and inwardly curved front wall 20. The wall 20 has an inturned lip 22 on its lower edge for engagement with a placard 24 and backing 25 which is received in the frame.

A pair of downwardly depending spaced-

apart lips

26, 28 are provided on the underside of the sidewall 18 and define a groove for reception of an edge portion-of one leg 30 of a corner mounting bracket 32. A horizontally extending wall 34 is provided intermediate the upper and lower edges of the front wall 20. The wall 34 has an upwardly extending lip 36 on its outer edge which, with the inner surface of the wall 20, defines a groove for the reception of the other edge of the leg 30. The grooves defined by the lips on the

walls

18, 34, also serve to receive the clip 38 of the invention, as will be later described.

The side frame members 12, 14 are similar to the top frame member but have added thereto an L-shaped portion 40 which extends inwardly from the curved wall. The L-shaped portion has

legs

42, 44 and defines, with the curved wall, a channel for the reception of the placard 24 and backing 25. The absence of the L-shaped portion from the top frame member 16 permits insertion and withdrawal of placards as desired.

As will be noted in FIGS. 1 and 2, the frame members are secured together by means of thebrackets 32. As previously described, the

legs

30, 46 are inserted into the oppositely disposed grooves provided in the

walls

18, 34.

Screws

48, 50 are threadingly received in openings in the

legs

30, 46. As shown in FIGS. 1 and 2, the enlarged screwheads overlap the adjacent groove lips to thus clampingly engage the lip and thereby secure the frame members together.

FIGS. 5-7 best illustrate the configuration of the clip 38. The clip 38 is preferably fabricated of a flexible material such -as nylon. The clip comprises a pair of spaced-apart, horizontally extending

base elements

54, 56. A bar 58 extends between the

elements

54, 56 intermediate the ends thereof. The bar 58 serves to rigidify the structure. A downwardly extending

projection

60, 62 is provided on the outer end of each

element

54, 56. An upwardly extending

rojection

64, 66 is provided on each

element

54, 56 spaced rearwardly from the

projections

60, 62. The

upper portion

68, 70 of each

projection

64, 66 is of reduced thickness to define notches 72, 74.

An arm 76 extends laterally from the'projection 64 towards the projection 66. The arm 76 terminates short of the projection 66. An upwardly extending projection 78 is provided on the rear edge of the outer end of the arm 76. A triangularlyshaped upwardly extending projection 80 is provided on the outer end of the arm 76 and on the forward edge thereof. The

projections

78, 80 define a channel 82.

An upwardly projecting generally V-shaped hanger element 84 extends between the rearward ends of the

base element

54, 56. The element 84 is for reception of a nail or other support element as indicated by the dash lines 88 of FIGS. 2 and 3. The apex 86 is curved for centering on the nail.

The method for insertion of the clip 38 into the top frame member 16 is shown in FIG. 8. The downwardly extending

projections

60, 62 are first inserted into the groove defined by the

walls

20, 34 and lip 36. The clip is then rotated in a counterclockwise direction whereupon the triangularly-shaped projection 80 engages the lip 28 of the upper wall 18. Further rotation of the clip causes the arm 76- to be deformed downwardly with the lip 28 sliding on the inclined surface 90 of the projection 80. When the projection 80 passes by the lip 28, the arm 76 springs upwardly back to'its initial position. Then, as shown in FIG. 3, the lip 28 is received in the channel 82 defined by

projections

78, 80 to thereby lock the clip in place.

When the clip has been received on a nail as illustrated in FIG. 3, the forces applied to the clip by virtue of the weight of the frame tend to rotate about the nail because of the lever action resulting from the

base elements

54, 56. The tendency to rotate causes the

projections

68, 70, 78 to engage the outer surface of the lip 28 and the

projections

60, 62 to engage the inner surface of the lip 36. The projection 80 thus does not have to act as a support member. The function of the projection 80 is merely to prevent separation of the clip from the frame as a result of transient forces such as may be present when hanging and centering the frame on a nail.

The clip 38 will slide freely in the frame member 16. This permits easy centering of the frame. A single clip may be utilized as shown in FIG. lfhowever, if necessary, several clips may be used to hang a frame. The clips may be readily removed by manually depressing the arm 76 to clear the lip 28.

An additional feature of the clip 38 is that the relatively large surface area of the hanger element 84, when it contacts the surface which supports the element 88, prevents tilting of the frame. The element 88 may thus be secured to a narrow strip, such as a shelf edge of the type frequently present in retail stores.
