Definitions
- Ready to assemble furniture is very popular because they can be relatively inexpensive as compared to fully assembled furniture and for ease of assembly.
- pieces of furniture that have been proven to be exceedingly difficult to provide as ready to assemble furniture. Reclining furniture with rocker, glider, swivel and other mechanisms create particular problems when used in ready to assemble furniture.
- the precision of preparing the interlocking parts is typically beyond the ability of the average person working with ready to assemble furniture.
- the present invention addresses this deficiency and provides a novel interlocking cam assembly whereby the interlocking cams are provided to allow for easier assembly of reclining and motion furniture.
- the multi-piece cam further provides a configuration that is more easily disassembled and serviced in the field.
- the present invention is a mechanism for assembling and connecting a furniture base to a piece of
- furniture comprising: a furniture base having a first cam, configured with a first cam interlock, associated therewith;
- a furniture frame having a second cam, configured with a second cam interlock, associated therewith;
- each of said first cam and second cam interlocks configured to mate and interlock one to another.
- the first cam is a system including two or more cam units.
- the second cam is a system including two or more cam units.
- the first cam has two or more first cam interlocks .
- the second cam has two or more second cam interlocks .
- the mechanism is configured to be used with a multitude of furniture bases including, but not limited to recliner mechanism bases, rockers, gliders, swivels, swivel rockers, swivel gliders, twin sleepers, full sleepers, queen sleepers, king sleepers, or combinations thereof.
- the first cam interlock is integrated onto said first cam.
- the second cam interlock is integrated onto said second cam.
- the first cam interlock and said first cam are constructed of a unitary piece.
- the second cam interlock and said second cam are constructed of a unitary piece.
- first cam interlock and said second cam interlock connect in a snap-fit locking arrangement.
- the present invention further contemplates a method of
- connecting a furniture base to furniture comprising the steps of: providing a first cam and second cam according to any of the configurations or combinations disclosed herein;
- Figure 1A is a side perspective view of a two-piece cam assembly configuration in separated position.
- Figure IB is a side perspective view of a two-piece cam assembly configuration in separated position.
- Figure 1C is a side perspective view of a four-piece cam
- Figure 2 is a side perspective view of a two-piece cam assembly configuration in a connected position.
- Figure 3 is a partial cross-section from Figs. 1A and IB with directional arrow indicating direction of connection of separate cam components.
- Figure 3 is a partial cross-section from Figs. 1A, IB, and 3 with separate cam components in a connected position.
- the present invention relates to a multi-piece cam assembly for furniture.
- the figures are demonstrative and the invention contemplates multiple configurations including, but not limited to two, three, four, and five cam component systems.
- the two-piece cam is suitable for assembling a furniture base to the seat box portion of furniture. It is further contemplated that the present invention is suitable for connection of reclining mechanisms to a base in ready to
- Reclining furniture is without limitation and includes, but is not limited to, a rocker, glider, swivel, swivel rocker, swivel glider, power variations of all of the above, sleepers, or any piece of furniture that utilizes reclining mechanism.
- the multi-piece cam assembly is suitable for all furniture where connection is desired.
- the two-piece cam is particularly well suited for connecting a furniture frame to a base.
- first cam configured as a receiving cam 20 is constructed and arranged with a locking orifice 24.
- Orifice 24 is constructed and arranged to interact with locking tab 34 on locking cam 32.
- Receiving cam 20 has formed thereon a horizontal support
- receiver 22 which is constructed and arranged to receive
- receiving cam 20 is constructed arranged with a curved lower surface 26 that interacts with the upper surface 28 of furniture base 30.
- cam 20 is flat and secured to base 30.
- Reclining mechanisms are typically exceedingly complex and furthermore locking mechanisms are often excluded from ready to assemble furniture products.
- the locking cam 32 of the present invention is constructed and arranged to affix to the seat box or scissor/main assembly of a reclining mechanism of a piece of furniture. In one embodiment, locking cam 32 is affixed to the seat box. In another embodiment,
- the seat box frame or recliner frame is formed with a cam portion integral therewith.
- locking cam 32 removably interconnect locking cam 32 with receiving cam 20.
- receiving cams 20 are provided in pairs .
- cam 20 is positioned over a prepared upper surface 28 of furniture base 30.
- Base 30 is constructed and arranged to have two main base portions each being 30 that are interconnected by transverse supports 38.
- Cam 20 has receiving socket 42 configured to mate with positioning tab 40 of cam 32.
- the multi- piece cam is contemplated to connect and disconnect in a male- female interlock arrangement.
- the two-piece cam represents a significant and unforeseen improvement in furniture design and construction by providing a construction element that improves ease of assembly and disassembly.
- the multi-piece cam assembly is suitable not only for rocking, reclining, and gliding assemblies, but for all furniture in which there is the attachment of a mechanism to a frame base.
- the invention is a mechanism for a piece of furniture comprising: two or more locking cams, constructed and arranged with at least one locking mechanism on each cam; two or more receiving cams, said receiving cams are constructed and arranged to receive said locking mechanism, said interconnected cams are configured to be used in reclining furniture and sleepers to include, but not limited to, rockers, gliders, swivels, swivel rockers, swivel gliders, twin sleepers, full sleepers, queen sleepers, king sleepers.
- this mechanism assembly covers power reclining variations.
- the multi cam configurations provide additional benefit relating to simplification of the assembly process.
