The present invention relates generally to powered furniture seating, and more particularly to a new and improved actuating mechanism or system for moving components of a powered furniture seating piece, such as, for example, a seat section and a back support pivotally connected to the seat section, and an extendable footrest or leg support, between a first position or state at which the seat section and back support are not tilted or reclined, the back support is disposed at a substantially upright position, and the footrest or leg support is disposed at a retracted position, and a second intermediate position or state, commonly referred to as a TV position, wherein the seat section and back support are not tilted or reclined, the back support is disposed at a substantially upright position, but the footrest or leg support is now disposed at an extended position, and a third position or state at which the seat section is disposed at a tilted position, the back support is disposed at a fully reclined position, and the footrest or leg support is disposed at the extended position. Still more particularly, the present invention is directed to a new and improved actuating mechanism or system for powered furniture seating wherein the powered furniture seating may comprise seating for a home or business, or seating for a theater or a stadium.
Various different actuating mechanisms or systems for powered furniture seating pieces are of course well known in the art. Some examples of such actuating mechanisms or systems are disclosed within U.S. Pat. No. 10,213,020 which issued to Lawson on Feb. 26, 2019; U.S. Pat. No. 10,383,443 which issued to Lawson on Aug. 20, 2019; U.S. Pat. No. 10,390,621 which issued to Lawson on Aug. 27, 2019; U.S. Pat. No. 10,485,347 which issued to Lawson et al. on Nov. 26, 2019; and U.S. Pat. No. 11,363,886 which issued to Johnson on Jun. 21, 2022. It is noted that while all of these actuating mechanisms or systems are viably operative so as to move various components of the powered furniture seating between a multiplicity of positions, all of such actuating mechanisms or systems comprise relatively complicated, complex, redundant linkage mechanisms or systems which are costly to manufacture and difficult to assemble.
A need exists in the art for a new and improved actuating mechanism or system. Another need exists in the art for a new and improved actuating mechanism or system for use in connection with powered furniture seating pieces. Still another need exists in the art for a new and improved actuating mechanism or system for use in connection with powered furniture seating pieces wherein the powered furniture seating piece comprises theater or stadium seating. Yet another need exists in the art for a new and improved actuating mechanism or system for use in connection with powered furniture seating pieces wherein the powered furniture seating piece comprises theater or stadium seating, and wherein the new and improved actuating mechanism or system can move a seat section and a back support, pivotally connected to the seat section, and an extendable footrest or leg support, between a first position or state at which the seat section is not tilted, the back support is not reclined so as to be disposed at or in a substantially upright position or state, while the footrest or leg support is disposed at a retracted position, a second position or state, commonly referred to as the TV position, wherein the seat section remains substantially horizontal while the back support remains substantially upright, however, the footrest or leg support has been moved to an extended position, and a third position at which the seat section and back support are disposed at tilted and reclined positions while the footrest or leg support is disposed at the extended position. Yet still another need exists in the art for a new and improved actuating mechanism or system for use in connection with powered furniture seating pieces wherein the powered furniture seating piece comprises theater or stadium seating, wherein the new and improved actuating mechanism or system comprises a simplified linkage assembly which can move a seat section and a back support, pivotally connected to the seat section, and an extendable footrest or leg support, between a first position or state at which the seat section is not tilted, the back support is not reclined so as to be disposed at or in a substantially upright position or state, while the footrest or leg support is disposed at a retracted position, a second position or state, commonly referred to as the TV position, wherein the seat section remains substantially horizontal while the back support remains substantially upright, however, the footrest or leg support has been moved to an extended position, and a third position at which the seat section and back support are disposed at tilted and reclined positions while the footrest or leg support is disposed at the extended position, and wherein the simplified linkage assembly is cost effective to manufacture and easy to assemble.
An overall objective of the present invention is to provide a new and improved actuating mechanism or system. Another overall objective of the present invention is to provide a new and improved actuating mechanism or system for use in connection with powered furniture seating pieces. Still another overall objective of the present invention is to provide a new and improved actuating mechanism or system for use in connection with powered furniture seating pieces wherein the powered furniture seating piece comprises theater or stadium seating. Yet another overall objective of the present invention is to provide a new and improved actuating mechanism or system for use in connection with powered furniture seating pieces wherein the powered furniture seating piece comprises theater or stadium seating, and wherein the new and improved actuating mechanism or system can move a seat section and a back support, pivotally connected to the seat section, and an extendable footrest or leg support, between a first position or state at which the seat section is not tilted, the back support is not reclined so as to be disposed at or in a substantially upright position or state, while the footrest or leg support is disposed at a retracted position, a second position or state, commonly referred to as the TV position, wherein the seat section remains substantially horizontal while the back support remains substantially upright, however, the footrest or leg support has been moved to an extended position, and a third position at which the seat section and back support are disposed at tilted and reclined positions while the footrest or leg support is disposed at the extended position.
Yet still another overall objective of the present invention is to provide a new and improved actuating mechanism or system for use in connection with powered furniture seating pieces wherein the powered furniture seating piece comprises theater or stadium seating, wherein the new and improved actuating mechanism or system comprises a simplified linkage assembly which can move a seat section and a back support, pivotally connected to the seat section, and an extendable footrest or leg support, between a first position or state at which the seat section is not tilted, the back support is not reclined so as to be disposed at or in a substantially upright position or state, while the footrest or leg support is disposed at a retracted position, a second position or state, commonly referred to as the TV position, wherein the seat section remains substantially horizontal while the back support remains substantially upright, however, the footrest or leg support has been moved to an extended position, and a third position at which the seat section and back support are disposed at tilted and reclined positions while the footrest or leg support is disposed at the extended position, and wherein the simplified linkage assembly is cost effective to manufacture and easy to assemble.
The foregoing and other objectives of the present invention are achieved by a new and improved actuating mechanism or system for use in connection with powered furniture seating pieces wherein the actuating mechanism or system comprises a base or foundation, and a linear actuator having its motor or rear end pivotally mounted upon the base or foundation, while its oppositely disposed telescopic rod or forward end is pivotally connected to a front motor drive tube which is mounted upon an ottoman drive link that has a first end portion thereof pivotally mounted upon a seat rail. It is noted that the linear actuator may be a mechanical actuator, an electrical actuator, a hydraulic actuator, a pneumatic actuator, or any suitable combination thereof, such as, for example, an electromechanical actuator. In addition, the ottoman drive link is operatively connected to a multiplicity of ottoman extension links which are pivotally connected to an ottoman support bracket upon which an ottoman, footrest, or leg support is mounted and supported. When the linear actuator is extended a first, predetermined amount, the ottoman, footrest, or leg support will be moved from a retracted or closed position to an intermediate TV position while a seat rail, upon which a seat section of the furniture piece is fixedly secured, will move forward a first predetermined amount but will remain substantially horizontal, and a back support, upon which a back section of the furniture piece is fixedly secured, will remain in a substantially upright state or position. However, when the linear actuator is extended further to its maximum extended position, the seat rail will be moved forwardly a second predetermined amount, while the back support, which is pivotally mounted upon the seat rail, will be moved from its upright position to a fully reclined position, whereby the furniture piece will now have attained its fully reclined position or state.
Various other features and attendant advantages of the present invention will be more fully appreciated from the following detailed description when considered in connection with the accompanying drawings in which like reference characters designate like or corresponding parts throughout the several views, and wherein:
Referring now to the drawings, and more particularly to
With reference now being made to
Accordingly, it can therefore be appreciated that as the linear actuator 204 is actuated so that the telescopic rod 210 thereof is extended to a first predetermined extent, which will be more fully appreciated hereinafter, the integral assembly, comprising the forward end of the telescopic rod 210, second clevis connection 212, front motor drive tube 214, and ottoman drive link 216, will cause the ottoman drive link 216 to pivotally rotate in the clockwise direction as well as causing the seat rail 218 to move forwardly a first predetermined amount. In turn, as the ottoman drive link 216 rotates in the clockwise direction, the ottoman drive link 216 will cause the first and second ottoman extension links 226,244 to pivotally rotate in the clockwise direction so as to, in fact, or in turn, cause the ottoman mounting or support bracket 234 to be moved to its extended state. It is to be noted that all of these movements occur until a mechanical limit stop, which is in the form of a first stop pin or rivet 250 and which is mounted upon an intermediate portion of the ottoman control link 230, comes into contact with a stop surface which is, in effect, an undersurface portion 252 of the ottoman drive link 216, whereby further movements are effectively prevented or arrested. Continuing further, it is also seen that a second opposite end of the ottoman carrier sequence link 238 is pivotally connected to a carrier link 254 as at 256, and it is to be further appreciated that as the ottoman control ink 230 undergoes its clockwise rotation, the ottoman carrier sequence link 238 will undergo a counterclockwise rotational movement. In addition, as can best be appreciated from
In a similar manner, an upper end portion of a rear control link 264 is pivotally mounted upon or connected to the seat rail 218 as at 266, while an intermediate portion of the rear control link 264 is pivotally connected to the carrier link 254 as at 268. Accordingly, as the seat rail 218 is moved forwardly through the aforenoted first predetermined amount, as a result of the aforenoted actuated extension of the telescopic rod 210 of the linear actuator 204 through its first predetermined extent, first front pivot link 258 will rotate in the counterclockwise direction around the pivotal connection 262 defined between the first front pivot link 258 and the carrier link 254, in view of the fact that the upper end portion of the first front pivot link 258 is pivotally connected to the seat rail 218 as at 260, and in a similar manner, rear control link 264 will likewise rotate in the counterclockwise direction around the pivotal connection 268 defined between the rear control link 264 and the carrier link 254, in view of the fact that the upper end portion of the rear control link 264 is pivotally connected to the seat rail 218 as at 266. It is further noted that this counterclockwise rotational movement of the rear control link 264 will continue until a lower or left side surface portion 270 of the rear control link 264 encounters a second stop pin or rivet 272 which is mounted upon a rear end portion of the carrier link 254. More particularly, and with specific additional reference being made to
With continued reference to
Accordingly, relative movement of the control link slot follower pin 276 with respect to the rear control link 264 is limited to movement within the first, upper rear control link slot 293, with movement at this time terminating at the juncture of the first and second, upper and lower rear control link slots 293,294, whereby the rear pivot link 278 does not undergo any movement with respect to carrier link 254 such that, as can therefore be further appreciated, the rear pivot link 278 does not undergo any movement as the mechanism or system 200 is moving the various structural components from the CLOSED position to the TV position. Still further, and as will become more apparent hereinafter, in view of the stationary disposition of the rear pivot link 278 during the movement of the mechanism or system 200 from the CLOSED position to the TV position, the angular orientation of the back support bracket 222 will remain unchanged, that is, it will retain its upstanding or upright orientation at this particular time. It is noted, however, that, concomitantly, in view of the fact that the back support bracket 222 is pivotally connected to the seat rail 218 as at 224, the forward movement of the seat rail 218 will result in the forward movement of the back support bracket 222 which, in turn, will cause the rear sequence link 286 to rotate in the counterclockwise direction as a result of the pivotal connection 288 defined between the rear sequence link 286 and the rear pivot link 278.
Continuing further, the movement of the mechanism or system 200 from the TV position to the full RECLINE position will now be discussed and described. Beginning with the various different components of the mechanism or system 200 as disclosed within
