United States Patent Ofiice 3,171 ,541 Patented Mar. 2, 1965 3,171,541 DISPLAY APPARATUS David Weisberger, 1411 Ellwood Ave., Mount Vernon, NX. Filed Mar. 5, 1963, Ser. No. 262,922 7 Claims. (Qi- 211-37) This invention relates to display apparatus and more particularly, to merchandise display racks having one or more shelves which are adjustable in slope.
Two highly desirable attributes of shelved display racks, such as those of the type useful in exhibiting retail merchandise, are a high degree of adjustability and a simplified procedure by which these various adjustments may be accomplished. Such racks when used in retail shoe stores, for example and without limitation, are often employed to accommodate merchandise of varying shapes, each of which for its most stable and attractive display may require placement on a shelf having a different horizontal slope. Ladies high heel shoes, for instance, have been found to present a particularly attractive display when placed on a shelf which is oriented at a relatively steep angle. Such an orientation, however, does not impair the stability of the display since the heels of these shoes may rest behind and engage the rear edge of the steeply sloped shelves, thereby preventing the shoes from sliding downwardly. Shoes with so-called low, or fiat, heels are also attractively displayed on sloped shelves, but, owing to the lesser depth of their heels and the resulting greater likelihood that such shoes when removed for inspection will not be properly replaced, considerations of stability require that the slopes of the shelves should be less steep than in the case of high heel shoes. Finally, such a rack may be called upon to display various flat bottomed articles such as bedroom slippers or any number of common accessories such as ladies handbags, costume jewelry and the like, in which case the shelves upon which these goods sit are preferably horizontal.
In order to provide a wide variety in the display of such merchandise, it is usual to readjust from time to time the slopes of these shelves. Where a display in one instance might be comprised of all high heel shoes, it might be desired to modify such a display by substituting all low heel shoes, all flat bottom goods, or a combination of these articles. This modification requires a corresponding readjustment in the slopes of the shelves involved. Moreover, in deciding upon the final version of a retail merchandise display a number of preliminary arrangements are usually explored, during which frequent readjustment of the shelves may be necessary.
Accordingly, it is one object of the invention to display a variety of different wares at various angular orientations.
It is another object of the invention to simplify the procedure for angularly readjusting shelves in a merchandise display rack.
The objects of the invention are accomplished, broadly, by the provision of a frame, first and second members mounted on said frame and relatively positioned to define at least a single shelf for supporting mechandise or the like, at least one of the aforementioned members being movable in sliding translation relative to the other member, and linkage means for imparting translatory motion to the movable members.
The objects, features and various advantages of the invention will be more thoroughly understood by reference to the following detailed description of an illustrative embodiment of the invention in conjunction with the accompanying drawing of which:
FIG. 1 is a perspective View of the invention embodied in a merchandise display rack;
FIG. 2 is a sectional view of the center guide bar of FIG. 1;
FIG. 3 is a fragmentary View of the display rack of FIG. 1 showing in detail the linkage mechanism of the invention;
FIG. 4 is an exploded view of a portion of the rack of FIG. 1; and
FIG. 5 is another fragmentary view showing the linkage mechanism of the invention.
With reference to the drawing, FIG. 1 shows one embodiment of a merchandise display rack constructed in accordance with the invention. As shown, the frame of the rack is wedge shaped in general outline, and comprises a pair of inverted V-shaped end members 1 and 2, the spread ends of which terminate in the corners of a rectangularly shaped platform bounded by rods 3 through 6, and the vertices of which are held in proper spaced relation by tie bar 17. The entire rack rests upon legs 7 which extend downwardly from the corners of the afore mentioned platform. A plurality of supporting members 8 through 14 spaced vertically from each other, extend horizontally between corresponding legs of V-shaped end members 1 and 2, and thereby form a front wall of the wedge shaped rack. Tie rods 11 through 13 which are spaced vertically from each other, connect together the front and rear legs of V-shaped end member 1 to form the left side wall of the wedge shaped rack. Tie rods 14 through 16 are similar to their counterparts 13 through 11 with respect to V-shaped end member 2, and form the right side wall of the wedge shaped rack. A rod 18 is rigidly connected to the midpoints of rods 4 and 6.
Extending upwardly from a sleeve 67 on rod 18 is a vertical guide bar 19, the upper end of which is suitably bent for lateral insertion into sleeve 61 of the tie bar 17. Rigidly connected along guide bar 19 are several pairs of split sleeves 20. As shown in FIG. 2, the individual sleeves 2d of each pair reside on opposite sides of bar 19, and each pair of sleeves is disposed in vertical alignment with the pair of sleeves above. The casing of each sleeve 20 is split in order to provide a vertical opening 21 which is located diametrically opposite to guide bar 19. Rigidly connected to tie rods 11 through 16 on the inside of the wedge shaped frames are individual sleeves 22. It will be observed that the sleeves associated with the respective V-shaped end members 1 and 2 are in vertical alignment with each other. Each of sleeves 22 is split to provide a vertical opening 23 diametrically opposite to the tie rod to which that sleeve is connected. Accordingly, the vertical openings 21 in the sleeves 211 which are situated to the right of guide bar 19 face the vertical openings 23 in the sleeves 22 which are connected to tie rods 14 through 16. Likewise, the vertical openings 21 in the sleeves 219 which are situated to the left of guide bar 19 face the vertical openings 23 (not shown) in the sleeves 22 which are connected to tie rods 11 through 13. Preferably, sleeves 2i) and 22 are constructed of resilient material.
Mounted vertically for sliding translation relative to the wedge shaped frame are ladder-like members 24 and 25 which are respectively located to the left and to the right of guide bar 19. Ladder-like member 24 is an integral structure comprising a pair of vertical runners 26 and 27 which are separated by spaced horizontal rungs 23 through 38. Ladder-like member 25 is identical to ladder-like member 24 and comprises vertical runners 31 and 32 which are separated by spaced horizontal rungs 33 through 35'. The slidable mounting for ladderlike structure 2-1 is provided by respectively inserting runners 2d and 27 through openings 21 and 23 of the sleeves 2d and 22 which are disposed to the left of guide bar 19. Similarly, the slidable mounting for 'of guide :bar 19. Accordingly, the diameter of runners 26, 27, 31 and 32 are slightly smaller than the inside diameter of sleeves 2t) and 22 so that sliding may occur with minimum friction. The resiliency of sleeves 20 and 22 permits the runners 26, 27, 31 and 32 to be snapped into proper position through vertical openings 21 and 23.
It will be observed that thevertical spacing of rungs 28 through 30-and 33 through 35 on ladder-like structures 24 and 25, respectively, correspond to the vertical spacing of supporting members 8 through 10. Thus, the rungs 28 through 30 and left-hand portions of supporting members 8 through define a first group of stacked shelves, the. slopes of which are determined by the vertical position of ladder-like structure 24. Likewise, the rungs 33 through 35 and the right-hand portions of supporting members 8 through 10 define a second group of stacked shelves, the slopes of which are determined by the vertical position of ladder-like structure 25.
In accordance with one feature of the invention linkage means are provided for applying independent vertical forces to ladder-like structures 24 and 25, thereby to slidingly vary the vertical position of one of the ladderlike structures relative to the other, and thus'to slidingly vary the slopes of one group of stacked shelves relative to the other. One illustrative arrangement for applying the aforementioned independent vertical forces to ladderlike structures 24 and 25 is shown in FIGS. 1 and 3. As pictured in FIG. 1, a pair of separate coaxial shafts 36 and 37 are mounted beneath the rectangular platform defined by rods 3 through 6 in a direction parallel to rods 4 and 6. The far ends of shafts 36 and 37 extend. loosely through rings 38 and 39, respectively, which are affixed to the undersurfaces of rods 3 and 5, and the near ends, as shown in detail by FIG. 4, are rotatably supported in a horizontal sleeve 40.
Rigidly connected to the respective far ends of shafts 36 and 37, slightly beyond the side walls of the wedge shaped frame, are lever arms 41 and 42 which extend forward in planes parallel to rods 3 and 5. Rigidly connected to the respective shafts 36 and 37, slightly Within the side walls of the wedge shaped frame, are first linkage arms 43 and 44 which extend in a rearward direction in planes parallel to rods 3 and 5. Second linkage arms 45 and 46, respectively, are pivotally connected to the ends of arms 43 and 44 remote from shafts 36 and 37, and from there extend generally upward for rigid connection to runners 27 and 32 via sleeves 47 and 48; In order to distribute the independent vertical forces uniformly across the respective ladder-like structures 24 and 25, linkagearms 4-3 and 45,'which are disposed at the far end of shaft 36, are duplicated at the near end of shaft 36 by a corresponding set of linkage arms 43' 4 to properly rotate the particular lever arms, 41 or 42, associated with the group of shelves to be adjusted. For example, if it is desired to'increase the slopes of the shelves comprising the left-hand group, it is necessary only to rotate lever arm 41 downwardly as indicated in FIG. 3. In response, shaft 36 is rotated in the direction indicated by the appropriate arrow in FIG. 3, and linkage arms 43 and 43 are consequently rotated upwardly. As
and and linkage arms 44 and 46, which are disposed at the far end of shaft 37, are likewise duplicated by a corresponding set of linkage arms 44' and 46'.
Extending downwardly from rod 3, at a point forward of shaft 36, is an arcuate tab 49 having several vertically spaced and outwardly protruding balls 56 rigidly connected thereto. Extending downwardly from rod S, at a point forward of shaft 37, is a planar tab (not shown) which is similar in both construction and function to tab 49 of rod 3. Tab 49 is situated so that lever arm 41 slidingly engages balls and is thereby selectively positioned in rotational angle. The aforementioned tab associated with rod 5 positions lever arm 42 in rotational angle in the same manner that tab 49 positions lever arm 41.
The apparatus described above provides a merchandise display rack having a left-hand group and a right-hand. group of stacked shelve-s which are defined by front and rear horizontal bars.
If it is desired to vary the slopes of the shelves of one of the groups, it is only necessary a result, the vertical component of force at the pivoted end of linkage arms 43 and 43' are transferred through linkage arms 45 and 45' to the runners 26 and 27 of ladder-like structure 24. Thus, by merely rotating lever arm 41, a vertical force is applied so as to slidingly raise rungs 23, 2and 36 relative to supporting members 8, 9 and 10, and thereby slidingly vary the slopes of the left-hand group of stacked shelves relative to the righthand group. A- similar result is obviously obtained with respectto the right-hand group of shelves by merely rotating lever arm 42. Preferably, the sleeves 20 and 22 are of large enough inside diameter with respect to the diameters of runners 26, 27, 31 and 32,.and all of the various linkage arms are sufliciently flexible, that the slight nherent components of horizontal force applied to arms 45, 45, 46 and 46 owing to the circular paths described by the pivotal ends of arms 43, 43', 44 and 44' do not substantially increase the dynamic friction involved vertically in sliding ladder-like members 24 and 25.
In the embodiment of the invention illustrated in FIGS. 1 and 3, the preselected vertical levels to which ladderlike structures 24 and 25 may be raised, and consequently the various preselected slopes of the groups of stacked shelves, are determinedby the relative positions of balls 50 on tab 49 for the-left-hand group, and on the corresponding tab (not shown) depending from rod 5 for the right-hand group. As shown, lever arm 41 is held in rotational position by its being lodged between a pair of adjacent balls 50. Preferably, the resiliency of lever arm 41 issufficient to permit the lever arm to be frictionnear the bottom of the frame close to the floor, and the latch mechanism is located at the top of the frame, the
.angular orientation of a group of stacked shelves may conveniently be varied by, firstly, pulling latch 52 out of engagement with the teeth of rack 51, secondly, manipulating lever arm41 by foot, and finally, releasing latch 55.
52 back into locking engagement withrack 51 when the desired slopes have been reached. A similar latch and rack mechanism (not shown) is disposed on end member 2 and runner 32 so as to vary the slopes of the shelves of the right-hand group in the same manner.
In all cases it is to be understood that the'particular embodiments of the invention described herein are merely illustrative of .the underlying principles involved, and numerous other arrangements, modifications and adaptations may be conceived without departing from the spirit andscope of the invention.
