Chair with extendable footrest

Abstract

The present invention is a chair having a footrest that is extended when in use and retracted when not in use, have more space for comfortably positioning feet of a user/patient having more weight and is stable to provide safety. Chair includes a pair of leg frames, a pair of brackets, at least a pair of rollers, a footrest, at least one lever, gliding pins and wheels. Brackets are defined with railings and positioned on leg frames of chair. Rollers are connected to footrest and positioned to roll along the length of railing thereby enabling footrest to extend and retract. Footrest is of a size such that it is completely positioned between legs of chair to provide more feet resting area. Wheels are positioned underneath footrest for easy movement. Gliding pins connect wheels and footrest. Lever limits footrest movements and enables manipulating footrest with an extended handle.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

(8) Referring now to the drawings, FIGS. 1-6, where the present invention is generally referred to with numeral 10, it can be observed that a chair, in accordance with one embodiment, is provided that mainly includes a pair of leg frames 20, a pair of brackets 30, at least a pair of rollers 40, a footrest 50, at least one lever 60, a pair of gliding pins 70 and wheels 80.

(9) Pair of leg frames 20 is provided on respective legs 21 of chair 10. On respective legs 21, pair of leg frames 20 is provided underneath a handle portion 22. In one embodiment, pair of leg frames 20 is made of wooden material. In another embodiment, pair of leg frames 20 can be made of any other material similar to the material of chair 10 like polymeric or metallic materials. Leg frames 20 are provided with a receiving portion (not illustrated in Figures).

(10) Brackets 30 are fixedly fitted along the body of the respective leg frames 20. Each bracket 30 is defined with a railing 31 that is fitted in the corresponding receiving portion of leg frame 20. Typically, brackets 30 are made of aluminum material so as to provide strength to wooden leg frames 20. Alternatively, brackets 30 can be made of any other metallic or polymeric material that can increase the strength of leg frames 20. Although the present disclosure is described with brackets 30 and leg frames 20 as independent components, however, brackets 30 and leg frames 20 can also be integral or a single component.

(11) At least one roller 40 is disposed of in each railing 31 such that each roller 40 rolls along the length of respective railing 31. Typically, rollers 40 can be made of any material like polymeric or metallic or metallic coated with polymeric.

(12) Footrest 50 is positioned centrally and disposed on oppositely positioned rollers 40 and configured to extend and retract upon rolling movement of rollers 40. Size of footrest 50 is more as footrest 50 is of a size equal to sitting area of chair 10 because footrest 50 when in retracted configuration complete occupies the area between four legs of chair 10.

(13) In one embodiment, levers 60 can be optionally provided and connects footrest 50 and a portion under seat 12 of chair 10 and limit the movement of footrest 50 within the limits of rollers 40. Levers 60 can be a single component or can be provided with a connection to achieve a connection. Levers 60 can also have an extended handle (not illustrated in Figures) that when operated enables to easily push and pull footrest 50.

(14) Gliding pin 70 is provided that connects rollers 40 with footrest 50.

(15) Wheels 80 are fitted underneath footrest 50 to support footrest 50 and enable easy movement of footrest 50 along with movement of chair 10.

(16) Chair 10 can be used as a stationary chair or can be portable by attachment of wheels such that a patient who can have recently undergone hip or knee operation can comfortably position their feet on extended footrest 50. A user or a patient more in weight needs more feet positioning space and hence extended footrest 50 of the present disclosure having more surface area provides desired space for comfortably positioning feet. Also, footrest 50 is capable to withstand more weight of user or patient and hence prevents footrest 50 from breaking. Also, assembly of footrest 50 with leg frames 20 provides stability and safety.

(17) The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
