The subject disclosure relates to the art of shelving systems and, more particularly, to a shelf having a bi-directional slide and tilt mechanism.
Various shelf systems include shelves that may slide out from a housing. In some cases, shelves may be able to tilt downwardly to facilitate access to articles supported thereon. Often times, an upper most, or upper shelves are able to tilt downward to provide enhanced access. The shelf may slide from an end stop outwardly and, at a certain point, may be tilted downward. The downward tilting is not achieved through any particular mechanism but rather facilitated by a spacing between shelves and a height of a storage unit. That is, the shelf itself may be tilted downward when withdrawn a certain distance from a housing.
Generally, the storage unit or shelf includes a rear stop that prevents insertion beyond a certain point. This prevents, for example, the storage unit or shelf from falling out of a rear portion of the housing. Further, the use of a stop allows the housing to include a single locking mechanism that prevents unauthorized withdrawal of the storage unit or shelf. Many current shelving systems include a loading end and a removal end.
More specifically, the shelf may slide in a first direction to be loaded and in a second direction to be unloaded. Loading and unloading upper shelves can be difficult for certain individuals. Simply allowing a shelf to hang downward to be loaded or unloaded can lead to accidents such as a shelf falling from a cabinet. Accordingly, it is desirable to provide a shelving system including shelves, particularly upper most shelves, that have a bi-directional sliding and tilting mechanism to enhance access to products.
Disclosed, in accordance with a non-limiting example, is a shelving system including a cabinet including a product receiving zone. The product receiving zone includes a first end, a second end that is opposite the first end, a first side and a second side that is opposite the first side.

In a non-limiting example, first shelf support 155 is arranged in first track 167 and second shelf support 156 is arranged in second track 169. In a non-limiting example, as shelf member 44 transitions from first end 22 of cabinet 10, first shelf support 155 releases from first track 165. Shelf member 44 continues to move outward until second shelf support 156 engages the end stop at second end 175 of second track 169. At this point, shelf member 44 may tilt downwardly and rest on first angled support surface 40 of angle control bar 38 as shown in
Similarly, as shelf member 44 transitions from second end 24 of cabinet 10, second shelf support 156 releases from second track 169. Shelf member 44 continues to move outward until first shelf support 155 engages the end stop at second end 172 of first track 167. At this point, shelf member 44 may tilt downwardly and rest on first angled support surface 40 of angle control bar 38 as shown in
Reference will now follow to
In a non-limiting example, second portion 182 includes an axle 186 coupled to support frame 11 and extending between first end 22 and second end 24 of cabinet 10. Axle 186 supports a worm gear 188 that is operatively connected to gear 184. Axle 186 also supports a hand wheel 191 which, when rotated shifts switch member 95. In a non-limiting example, activation system 177 includes another gear 198 coupled to a switch member (not shown) on second side 30. Another axle 200 extends between first end 22 and second end 24 at second side 30. The another axle 200 supports another worm gear 210 that is operatively connected to the another gear 198. Axle 186 is operatively connected to the another axle 200 through a chain and sprocket system 220. With this arrangement, operation of hand wheel 191 activates switch member 95 on first side 26 and the switch member (not shown) on second side 30. Further, hand wheel 191 can be set up to simultaneously operate switch members in each of product receiving zones 12a-12c in first row 15.
In a non-limiting example, hand wheel 191 may be rotated to set switch member 95 such that guide channel 104 connects second section 78 of first track 71 with third section 80 of second track 73 to promote withdrawal of shelf member 44 from first end 22. Shelf member 44 is withdrawn causing first shelf support 56 to transition from first section 77 of first track 71 and second shelf support 57 passes through guide channel 104 into third section 80. With first shelf support 56 no longer being supported by first section 77, shelf member 44 tilts downward as shown in
At this point, it should be appreciated that the disclosed non-limiting examples describe various systems that facilitate the withdrawal and tilting of a shelf from opposite end of a cabinet. The various system include structure that supports the shelf in the tilted position and also contains further outward movement when tilted. The sliding and tilting of the shelf facilitates loading and removal of goods particularly from shelves arranged in a top portion of the cabinet. Also, in addition to the mechanical systems described herein, a bi-directional slide and tilt mechanism that includes an electrical activation system is also contemplated.
