## Background
FIELD OF THE INVENTION
The present invention relates to a chair system. More particularly, in its preferred intended use, the present invention relates to a reclining chair system that is operable about different modes and configurations, and that comprises an integrated extensible footrest. The present invention also relates to a method of operating said chair system, and to a kit for assembling the same. The present application claims priority of U.S. provisional patent application No. 60/717,237 dated Sep. 16, 2005, the content of which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
Is it well known in the art that there exists different types of rocking and reclining easy chairs on the market, and that these conventional chairs present drawbacks and inconveniences, particularly when compared with the components, features and functions of the present invention, as will be explained in greater detail hereinbelow.
Indeed, the ones offering similar functions use a completely different rocking and extensible footrest mechanism. The motion and the length of the glide is much shorter, the position of the backrest and seat when reclined is not the same angle, and the extensible footrest is not deployed in the same manner. The concept and the components used are different. With this type of mechanism, typically sold by LeggetTM and PlattTM, a shorter rocker arm is used, and the distance between the rocker arms is shorter as well. When the chair is in the reclined position, the rocking action is halted differently. The swivel/gliding/extensible footrest mechanism assembly has no resemblance to that of the present invention, as will also be explained hereinbelow.
It is also known in the art that a conventional reclining chair typically has two manual hand levers situated on each side of the easy chair. One hand lever is used to deploy the extensible footrest, and the other lever is employed to stop the rocking action. Also, the inclination of the seat and backrest are generally independent of the other functions.
It is also known in the art that for another type of fully upholstered recliners with footrests, like La-Z-BoyTM brand, BerklineTM brand, etc., the brackets for the footrest and the components used for the rocking action are very different from the smooth, long gliding action found on a rocker recliner with ball bearing arms.
None of the conventional easy chairs known in the art combine the long smooth gliding action found with bearing arms, or an extensible footrest which deploys from simply pushing back on the backrest, with no hand lever mechanism being necessary.
Hence, in light of the aforementioned, there is a need for such an improved reclining chair system which would be able to overcome and/or remedy some of the above-discussed prior art problems.

In its preferred intended use, the reclining chair system 1 according to the present invention, as exemplified in the accompanying drawings, is a type of easy chair that rocks, swivels, and reclines the backrest 21, while an extensible support is deployed from underneath the seat to serve as a footrest 11. This easy chair system 1 preferably does not employ any hand lever to recline the backrest 21 or to deploy the extensible footrest 11 or to stop the rocking action. The reclining chair system 1 according to the present invention preferably works as follows:
As can be easily understood by a person skilled in the art in view of the accompanying drawings and the above description, the integrated extensible support is deployed from underneath the seat to support the legs and feet of a given user of the reclining chair system 1. Preferably, to recline the back of the chair and activate the deployment of the extensible footrest 11, one can simultaneously push backwards on the back cushion of the chair while holding onto the armrests of the chair. Preferably, when the recline mechanism and extensible footrest 11 is activated, the gliding action of the chair is automatically halted, while the 360° swivel action is still functional, as previously explained, and as can be easily understood when referring to FIGS. 2-5 and 13-14. The present chair system has preferably different operation modes, positions and configurations. In a first position, the chair rocks and swivels and the extensible footrest is neatly folded up underneath the seat, as better shown in FIGS. 2 and 3. The feet of a user may touch the floor to permit rocking and swiveling. Preferably also, to arrive at a second position, one can push backwards on the back cushion (i.e. backrest 21) while holding preferably onto the armrests as described above, and the seat 19 and backrest 21 will recline while the extensible footrest 11 will deploy to support the legs of a user. In this position, the chair will no longer rock or glide back and forth, but the swivel action is still functional. The third position is preferably obtained in the same way as the second by pushing backward while holding the armrests. The angle of the seat reclines in proportion to the back cushion and the extensible footrest 11 is fully extended and raised, as shown in FIGS. 13 and 14. Again, and preferably also, the chair will swivel but not rock, in that particular configuration.
The reclining chair system 1 according to the present invention presents several features. Indeed, with this type of mechanism, the same features of regular, existing ball bearing gliders, such as the length of the glide, the smoothness of the bearing arms, the height of the chair and the seat, as well as the overall dimensions of length and width are maintained. By adding and modifying an extensible footrest 11 underneath the seat, one can now target two markets, the motion chair category, as well as the recliner category.
The exclusion of a manual lever to perform the various recline positions and to deploy the extensible footrest 11, makes the present system 1 unique and easy to operate, while conserving the features of two products that touch two different markets.
In regards to the assembling of the reclining chair according to the present invention, and in view of the accompanying drawings, it is preferably carried out as follows:
The circular base 3 attaches to the horns 35,37, with the two conical ball bearing casings inserted into the shaft. The chair base 3 is formed by the circular base attached to the horns 35,37. The assembly of these components enables the chair system 1 to swivel 360° degrees.
The two bearing arms 41f,41r are connected to the horns at the base 3 of the chair and to the side frames 7l,7r of the chair. The two side frames 7l,7r of the chair are connected to the chassis 9, via corresponding brackets, and fasteners, as better shown in FIG. 4. This forms the base 3 and sides of the chair.
Starting with the base and sides of the chair, the brackets for the footrest 11 must be fixed to the chassis 9 of the chair. Once assembled, the seat 19 and backrest 21 can be fastened to the support brackets 53 of the extensible footrest 11. This concludes the final step in assembling the finished product.
Additional preferred technical features of the components of the reclining chair system 1 according to the present invention are briefly described hereinbelow.
The circular base 3 supports the chair. The horns 35,37 which the bearing arms 41f,41r are bolted to are preferably attached to the circular base 3. The height of the base 3 is an important variable to ensure maximum space between the top of the horns 35,37 and the bottom of the seat 19. The ball bearings in the conical casings are preferably inserted into the circular base 3 to allow the horns 35,37 to swivel.
The horns 35,37 preferably support the bearing plates 43, held together by a crossbar 45 and permit the easy chair to swivel 360° degrees when attached to the circular base 3. The angle of these horns 35,37 is important as this will allow the proper clearance underneath the seat 19 while maintaining the appropriate height of the bearing arms 41f,41r to allow back and forth gliding.
Preferably also, the rocker arms contain ball bearings sealed in a casing. This is what allows the chair to glide back and forth. The distance between the center of each ball bearing casing is what determines the length of the glide, as can be easily understood by a person skilled in the art.
The rocker arms are preferably bolted to and support the sides of the chair. The front bearing arm and the rear bearing arm are also preferably bolted to the horns 35,37.
The chassis 9 supports the left and right mounting brackets 51 of the footrest 11 as well as the left and right side frames 7l,7r of the chair. Most of the overall weight preferably rests on the chassis 9. The size of the chassis 9 is preferably limited to maintain the backward and forward gliding action. This chassis 9 skims over with out touching the horns 35,37 while gliding. An important aspect resides in creating a solid chassis 9 capable of supporting the overall weight of the chair while the dimensions remained restricted to allow the back and forth gliding action.
The left and the right support brackets 53 must support the seat 19 and the backrest 21 and are fixed to the chassis 9. The movement of the support brackets 53 with respect to the mounting brackets 51 allow the footrest 11 to extend out from underneath the seat. The support brackets 53 are devised to attach to the backrest 21 and seat 19. Another function has been added to stop the rocking action without the use of a manual mechanism. When the recline position is obtained by pushing backward on the backrest 21 while holding onto the arms, a hooking member 77 engages the bearing arms or “stoppers” 73 to stop the rocking action. This is one of the most important functions of the present system 1. Indeed, when weight is transferred in the chair by pushing backwards, the rocking action is halted, when the hooking members 75 are hooked against the corresponding stoppers 73. When weight is transferred in the chair forwards in a given manner, the hooking members 75 become unhooked and the footrest 11 will automatically retract and the chair will once again rock with out any manual devise or mechanism to release the rocking function. The seat 19 and the backrest 21 of the chair are preferably attached to the footrest brackets 53.
Preferably also, the two hooks are attached to the left and right support brackets 53 of the footrest 11. They hook onto the stoppers 73 which are preferably attached to the rear horns 37 and stop the rocking action, as previously explained.
The extensible footrest mechanism is preferably adapted and modified to fit on a swivel, ball bearing gliding recliner functions without any manual mechanism or hand lever. The concept to combine a ball bearing glider and a recliner with integrated extensible footrest according to the present invention must take into account the following considerations: a) the stability of the chair; b) retain the long glide length; c) the balance of the chair, so it does not tip over while gliding or reclining; d) the switch from gliding action to a stopped position without the use of a manual lever; e) the extension of the footrest while reclining the back and seat without the use of a manual lever; and f) installation and modification of the footrest brackets in a restricted space; as apparent to a person skilled in the art.
The different components of the reclining chair according to the present invention preferably interact among each other in the following manner:
The seat 19 and backrest 21 of the chair system 1 are preferably not held in place like a conventional gliding recliner. The seat 19 and backrest 21 are fastened to the support brackets 53. The chassis 9 which supports most of the weight must be appropriately solid to ensure the stability of the chair when it is in gliding mode. The chassis 9 is solidly attached to the side frames 7l,7r of the chair. The side frames 7l,7r of the chair are also held into place by the ball bearing arms.
Description of the glide length: the length of the bearing plates 43 and the distance between the ball bearings when attached to the circular base 3 gives the length of the glide.
The equilibrium of the chair with footrest brackets 51,53 installed is determined by the proper placement of said brackets. If it is placed too forward, the chair will tip while gliding. Also, the angle of these brackets 51,53 is important. If the chassis 9 where these brackets are attached is angled too much towards the rear, while reclining the chair, the brackets 51,53 will be too high and the legs will be raised in an uncomfortable position and the horns 35,37 will be hit.
Switching from gliding mode to stopped position without the use of a manual mechanism: when the chair is reclined either at the beginning or end of the rocking motion, the mechanism is deployed to stop the rocking action at a precise point and the footrest 11 is automatically deployed. This precise stopping point is calculated to prevent the chair from tipping backwards when in the recline position. The alterations to the support bracket 53 will allow the stopping action to occur while in any position of the glide length. The hooking assembly 71 attached to the footrest bracket 53 when employed will keep the chair from rocking. This hook mount will fasten and unfasten around the stopper 73 which is attached to support tubes on the base when the inclination of chair is forced backwards or forwards without the use of any manual lever or mechanism.
The extension of the footrest 11 when the seat 19 and backrest 21 are reclined without any manual lever. The seat 19 and backrest 21 are attached to the support brackets 53 of the footrest 11 which is attached to the chassis 9 of the chair. While pushing with the arms to recline the backrest 21, the seat 19 releases the brackets of the footrest 11 allowing it to extend with out the use of a manual lever.
As can also be easily understood from the present invention, the reclining chair and the various components thereof, are preferably made of a suitable material, such as steel and the like, providing suitable structural soundness, while enabling the system to be produced/manufactured/assembled according to a suitable process, and in a cost-effective manner, while being structurally rigid enough to carry out its proper functions, and withstand adverse operating/loading conditions. Other suitable materials may be used according to the present invention, as apparent to a person skilled in the art.
According to the present invention, the reclining chair and corresponding parts may be shaped and sized so as to accommodate different types of people and/or applications. Thus, it could be easily understood that several components and features may be added or modified to the body and corresponding supporting members of the system without departing from the scope of the present invention.
For example, modifications could be made to fit the footrest bracket 53 in a restricted space. Indeed, it can be easily understood that the modifications and alterations to this type of bracket 53 are necessary to ensure the extension of the footrest 11 and the retraction to fit neatly underneath the seat 19. If the bracket 53 is too large, it will knock into other components while the chair is rocking. Other possible modifications and alterations which could be made to the reclining chair system 1 according to the present invention would be to have the horns 35,37 modified as well as the height of the base 3; to alter the framework of the chassis 9; to modify also the brackets 51,53 for the footrest, as well as the hook assemblies 71 on the footrest bracket 53, and modifications could also be made to the attachment of the chassis 9 to the side frames 7r,7l of the chair.
As may now be better appreciated, the present invention, by virtue of its design and components, as briefly described hereinabove, is a substantial improvement over other related chair systems and/or methods of operating chair systems known in the prior art, namely, but not exclusively, for the different reasons given and explained herein.
Of course, numerous modifications could be made to the above-described embodiments without departing from the scope of the present invention, as defined in the appended claims.
