Abstract
A retaining device for refrigerator shelves, particularly for use in boats, trailers, and other moving vehicles. The device is made of spring wire for the purpose of exerting outward pressure at the lower ends. The lower ends have specially designed double U-shaped clips formed therein, the U-shape being tapered to accommodate variable shelf wire sizes. The clip is also offset from the main wire body so that when force is applied to the main body wire the grip of the clip on the shelf is increased.
Claims6
An adjustable article retaining device for use with a shelf, said shelf comprising a pair of spaced support rails and a plurality of spaced connecting wires extending perpendicular to said support rails, said adjustable retaining device comprising;
- a wire rod main body member having clip means at each end thereof for frictional retention and adjustment with the said spaced connecting wires when the device is in use therewith, and said clip means further including means for increasing the retaining friction thereof when the wire rod main body member has lateral force applied thereto by an article to be retained when said article tends to slide along the shelf, said clip means includes two U-shaped clips provided at each end of the main body member and spaced apart a short distance so as to provide the means for increasing the frictional retention force whenever force is applied on the upper portion of the main body member.
A device for use with refrigerator type shelves, said shelves being in a refrigerator type cabinet having side walls with oppositely located and horizontally disposed grooves in which the ends of the shelves rest, said shelves having main support rails with horizontally extending connecting wires connected thereto, said horizontal connecting wires normally extending from the front-to-rear of said refrigerator type cabinet, a device formed of a single piece of spring wire for adjustably and frictionally retaining containers of said shelves comprising:
- a main body member of the spring wire having a horizontal portion with vertical members of approximately the same length extending from each end of the horizontal wire portion so as to provide a spring action between the open unconnected ends of said vertical members, and said open ends of said vertical members each having a clip engaging portion thereon for frictional engagement with the horizontal supporting wires of the refrigerator shelves, and means as part of the clip engaging portions to effect an increase in the overall frictional retaining force thereof when an increase in force is applied to the main body member, and the said means as part of the clip engaging portions at the end of said spaced main body vertical members includes double U-shaped portions formed of the same wire as the main body member and in parallel relation thereto which are spaced a slight distance apart for the purpose of effecting the increase in frictional retention power of said clip engaging portions when force is applied on the upper portion of the main body member.
