a j /gyw United SHELF RACK Arthur Lori, Zurich, Switzerland, assignor to Firma Karl Steiner, Zurich, Switzerland This invention relates to a shelf rack with'supporting side frames and shelves which can be adjusted relative to said frames. Such racks are used for example in shops in order to display goods of all kinds which are intended for sale.
One object of the invention is to provide a shelf rack on which the shelves can be easily adjusted for height, inclination and in a forward and backward direction relative to the lateral supports.
Another object of the invention is to provide a shelf rack in which the adjustments of the shelves can be effected by a single person and without making use of any tools such as screw-drivers or spanners.
Another object of the invention is to provide a shelf rack with adjustable supporting means for the shelves which provide a rigid attachment of parts without making use of screws and the like.
Still another object of the invention is to provide a shelf rack the parts of which are simple and durable in construction and inexpensive to manufacture.
With these and other objects in view, my invention consists in the novel features of construction and arrangeatent-D The apertures are formed by punching-out tabs 6 from the walls, the tabs being bent away from the wall in a. direction pointing inward and downward. The bracket 2 (Fig. 3) is also provided with two similar tabs 7 spaced apart by distance equal to the distance between the tabs 6, so that the bracket 2 can be attached at any selected height to the support 1. When the bracket is so attached, the tabs 7which are directed obliquely downwarden"- gage with corresponding apertures 5, thus forming a connection on which loads applied from the above can be carried. Since the apertures .5 are provided on opposite sides of the support 1 as illustrated, the latter can be used as intermediate support between two shelves. It is to be understood that instead of being of rectangular cross section the support can be of other cross sectional shapes.
It will be seen from Figs. 1 and 2 that the projections 8 and 9, which are positioned one above the other, the
ment of parts as will be hereinafter referred to and more particularly described in the specification and claims. By way of example only, a number of embodiments of the invention will now be explained in greater detail with reference to the accompanying drawing in which:
Fig. l is a side elevation, and
Fig. 2 is avertical section of a first embodiment,
Fig. 3 shows a bracket used with the embodiment illustrated in Figs. 1 and 2,
Figs. 4 to 6 show three successive stages in the assembly of the stay and the side edge of the shelf,
Figs. 7 and 8 show two further embodiments of the side edge of the shelf,
Fig. 9 is a perspective view of another embodiment, and
Fig. 10 shows in section the connection of the attachable bracket with the side frame of the embodiment constructed in accordance with Fig. 9.
Figs. 1 and 2 show the connection to a vertical support 1 of a shelf 3 which consists of an angle iron. The load carrying connection is eifected by means of a sheet metal bracket 2 which can be attached at any selected height to the support 1. In the angle of the shelf 3 are slots 11 which are uniformly spaced and with one of which an upper projection 9 of the bracket 2 engages. A sheet metal stay 4 has angled hooks 13 at its ends 12, the hooks engaging with two other slots 11. The stay 4 also has a number of notches 10 which are located substantially along a circular arc and one of which rests upon a lower projection 8 of the bracket 2. In the assembled condition, as illustrated, the centre of curvature of the circular are formed by the notches 10 coincides with the upper projection 9 of the bracket 2.
As can be seen in Fig. 2, the vertical support 1 is of sheet metal and has front and back walls provided with equispaced apertures 5 positioned one above the other.
slots 11. and the notches 10 are so designed that the notches can be. disengaged by lifting up the shelf together with the stay.4. In this embodiment the upper projection 8 is longer than the lower projection 8, so that in an intermediate position the projection 8 is disengaged whilst the upper projection 9 is still in engagement with the slot 11. In this intermediate position it is then possible to alter the angular position of the shelf in which new position the shelf can be secured by lowering the shelf and the stay 4 to engage a notch and-the projection 8 because all notches 10 are equi-distance from the projection 9. Thus, the inclination of the shelf is determined by that one of the notches 10 which engages the projection 8.
When the support 1 carries two shelves a similar operation will take place also on the opposite side of the support to align both shelves.
When the shelf and stay is lifted off the support, it is easy to detach the hooks 13 of the stay 4 from the slots '11, and-to do this, the stay is rotated in the direction toward the plane of the shelf. After assembly, if the hooks 13 are replaced in other slots 11, the shelf 3 can be moved in a forward or backward direction with respect to the support 1. Figs. 4, 5 and 6 show three successive stages in the replacement of one of the two hooks 13 in a slot 11.
In the embodiment constructed in accordance wit Figs. 1 and 2, the shelf 3 is a frame consisting of angle sections. This frame can be used to support a wire basket 14 or any other suitable container for goods. It is to be understood that the shelf can also take the form of a solid board 15 as shown in Figs. 7 and 8. These figures show the construction of the side edges to provide the slots or recesses 11.
It will be appreciated that provided the length of the shelf is not too great, it may be mounted upon a single vertical support. Further, the same vertical support may have mounted upon it two shelves or sets of shelves, one shelf or set of shelves being mounted upon one face of the support and the other shelf or set of shelves on the opposite face of the support. Where, however, long shelves are used, it will normally be necessary to employ two spaced vertical supports each located adjacent one end of the shelf. In such an arrangement, shelves may still be inclined to the horizontal if required by suitably positioning the stay supporting the shelf.
Anoth r embodiment of the invention is shown in perspective in Fig. 9, some parts of the shelf 3 having been omitted for clarity. Those components which are the same as those shown in Figs. 1 and 2 have the same reference numbers. What is different is mainly the attachable bracket 20. In addition to the two tabs 21, the bracket has another tab 22 which projects inwardly and downwardly but is shorter in length than tabs 21 of the bracket and, after assembly, tab 22 rests upon the edge of an Patented Dec. 6, 1960 aperture 5 in the support 1. The tab-22 acts as a stop preventing the tabs 21 from jamming in the apertures 5 in which they are located andifixes the level of the bracket 20 accurately with respect to the support 1. In contrast to the lower projection 23 which is of the s'ame sha'pe as the projection 8, the upper projection 24 is of diiferent shape, in that it is not bent but extends upwardly from a plate 25 spot welded to the bracket 20. During the spot Welding process the position of the plate -2.5 is aligned by means of a tab 26 on the plate 2 5 which is inclined slightly and which extends into an aperture formed when tab 21 is punched.
7 It will be appreciated that instead of the stay 4 being formed with notches co-operating with a projection on the bracket, the stay may have a series of projections a selected one of which engages a suitably placed and dimensioned slot in the bracket.
' It will beseen from the description of the embodiments that the stand constructed in accordance with the invention offers numerous possibilities of adjusting the position of the shelves, all adjustment being performed very simply and without the use of any tools. In addition, the embodiments described above offer great advantages from a manufacturing point of view, since all components can be formed by punching and bending sheet metal and since all components can be assembled without expensive machining processes.
