BY fl 0 ATTUR/VfVJ r r 3,004,745 Patented Oct. 17, 1961 The present invention relates to a rotary shelf device, and more particularly relates to an improvement in such a device which is adapted for installation in kitchen cabinets, bars and other spaces in order to make items located in the back of the space readily available for easy access.
Generally rotary shelf devices have been used for attachment to kitchen shelves and cabinets, on counters, and other places to make stored goods more readily available for access or, to provide an attractive apparatus for display of goods so as tomake them readily available for observation and selection. The present invention is directed to improvements in such an apparatus.
It is an object of this invention to provide a rotary shelf device with a pressure sensitive adhesive coating so that the shelf may be quickly installed on any type of material and in the desired location.
A further object of the present invention is the provision of a removable cover that provides an attractive and easy to clean surface.
Yet a further object of the present invention is the provision of an inexpensive installation means which also provides a bearing point for the revolving shelf.
A still further object of the present invention is the provision of a rotaryshelf device having a plurality of shelves.
Another object of the present invention is the provision of a simple, inexpensive, and easy to manufacture rotatable shelf device.
Other and further objects, features and advantages will be apparent from the following description of presently preferred embodiments of the invention, given for the purpose of disclosure and taken in conjunction with the accompanying drawing where like character references designate like parts throughout the several views, and where:
FIGURE 1 is an elevational view illustrating a rotary shelf device according to the present invention,
FIGURE 2 is a view taken along the line 22 of FIGURE 1,
FIGURE 3 is an enlarged partial view, in cross-section, taken along the line 33 of FIGURE 1 illustrating the pivot connection and a modified means for installation,
FIGURE 4 is an enlarged fragmentary view, in crosssection, illustrating one means of installation and a removable shelf cover,
FIGURE 5 is a side elevational view illustrating a modified form of the present invention having a plurality of rotary shelves, and
FIGURE 6 is a fragmentary view taken along the line 6-6 of FIGURE 5.
Referring now to the drawings and particularly to FIGURES 1, 2 and 3, thereference numeral 10 generally designates the rotary shelf device of the present invention and includes generally the circular shelf 12 which is securely mounted upon pivot member 16 which projects through the bearing plate 14 which is adapted to be secured to kitchen cabinets, shelves, counters and the like as will be more fully described herein.
The rotary shelf 12 is preferably circular and may be made of any desired material such as metal, wood or plastic. A retaining band 18 may be provided around the outer periphery of shelf 12 to act as a guard rail to retain goods on the shelf 12. The shelf 12 is preferably provided with a hole 13 for a press fit mounting of the shelf 12 on the pivot member 16. The pin member 16 may be permanently secured to the shelf 12 by a head (not shown) formed on the top of the pin member16. The bearing, plate may be comprised of any desirable material such as wood, metal or plastic and is provided with an'opening 15 and a dimpled washer 17, if desired, for the passage of pivot member 16 which preferably is a steel pin. Thus the shelf 12 and. the pivot member 16 rotate as a unit and are supported on the hole 15 or the washer 17. This is preferable as the shelf 12 is prevented from tipping over when unbalanced loads might pull the shelf'off a loosely fitting center pin.
Referring to FIGURES 1, 2 and 4, one method and means of installation of the rotary shelf device to a desired member 40 is shown. Tacks or nails 22 are provided which have a point 24 and a round head 26. These tacks 22 project through the bearing plate 14 and secure the rotary shelf device 10 to the desired member 40. Also it is noted that the round head 26 provides a bearing surface or slidable support for the shelf member 12 which is desirable if the shelf is heavily loaded or unevenly loaded. Preferably a plurality of tacks 22 are circularly spaced around and through the bearing plate 14.
Referring now to FIGURE 3, another method and means of securing the rotary shelf 10 to a desired location is shown. A pressure sensitive adhesive coating 20 is provided on the lower surface of the bearing plate 14. As this type of adhesive is well known no further description is believed necessary. Thus, the rotary shelf 10 may be installed in the desired location by merely pressing the bearing plate 14 or shelf 12 into position. This method of installation is advantageous in many instances where securing means such as the tacks 22 are not desired or could not be. used because of the nature of the location such as metal kitchen cabinets.
Referring now to FIGURE 4, a removable cover 30, which is preferably plastic, includes an annular band 34 and an integral web 32 of the same size as the shelf 12 may be provided to form a protective and easy to clean structure over the shelf 12. This plastic cover may be of any desired color or pattern so as to provide the desirable decorative qualities. Furthermore, by the use of this cover 30 with its annular band 34 the retaining band 18 may be omitted from the shelf 12.
Referring now to FIGURES 5 and 6, a rotary shelf device having a plurality of shelves is shown. In addition to the shelf 12 a similar shelf 38 is provided which is secured to shelf 12 by supporting means 36-. The supporting means 36 may be a wooden dowel and may be secured to the shelf 12 by nails 39, screws (not shown), or any other conventional means. Shelves 38 and 12 could also be provided with a plastic cover 30 if desired, in which case the cover for the lower shelf could be provided with a slit and opening for removal and installation on the lower shelf. Of course, a plurality of shelves could be provided and various means could be used to interconnect them. And, of course, the shelf 12 may as shown in FIGURE 6 rotate on or with the pivot member 16, espmially if used with the tack installation so that unbalanced loads may be supported on the tack heads 26.
In use, the entire assembly is preferably permanently assembled at the factory with the bearing plate 14 secured to the shelf 12 by the pin 16. In installing the shelf the pressure required to imbed the tacks or secure the adhesive may easily be transmitted through the shelf 12 to the tack heads 26 or the bearing plate 14, thus requiring nothing more for installation than placing the shelf 10 in location and firmly pressing downward on the entire assembly. The shelf 12 or plurality of shelves 12 and 38 may then be provided with a plastic cover 30. The shelf 12 now may be freely rotated with respect to the bearing plate 14 to place the shelf and its goods in the desired position. In the case of the tack supports 22 with the round head 26 the shelf 12 is provided with additional and inexpensive supports or bearing surfaces. It is noted that from time to time the plastic covers 30 may be conveniently removed and cleaned and reinstalled without the necessity of removing the rotary shelf device 10.
The present invention, therefore, is well adapted to carry out the objects and attain the ends and advantages mentioned as well as others inherent therein. While presently preferred embodiments of the invention are given for the purpose of disclosure, numerous changes in the details of construction and arrangement of parts a may be made which will readily suggest themselves to those skilled in the art which are encompassed within the spirit of the invention and the scope of the appended claims.
