BACKGROUND OF THE INVENTION

(1) Field of the Invention

The disclosure relates to wheelchair devices and more particularly pertains to a new wheelchair device for providing a convenient way for wheelchair users to rest or be cared for.

(2) Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98

The prior art relates to wheelchair devices. Most existing wheelchair devices are either in a fixed upright position or have an adjustment mechanism to change the angle of inclination for user comfort without offering a fully reclined position. Other devices include actuators or transform into full gurneys, rather than offering a simple locking pin and support to allow the back to fully recline.

BRIEF SUMMARY OF THE INVENTION

An embodiment of the disclosure meets the needs presented above by generally comprising a chair base frame having a base front side, a base back side, a base left side, a base right side, a base top side, and a base bottom side. A plurality of wheels is coupled to the chair base frame. A seat bottom is coupled to the base top side of the chair base frame. A pair of pivot brackets is pivotably coupled to the base top side adjacent the base back side of the chair base frame. A chair back is coupled to the pair of pivot brackets and moves between an upright position and a reclined position. A pair of bracket supports is coupled to the base back side adjacent the base top side of the chair base frame. The pair of pivot brackets rests on the pair of bracket supports when the chair back is in the reclined position. A pair of locking pins is coupled to the pair of pivot brackets. Each locking pin is selectively engageable with the base top side to secure the chair back in the upright position.

There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.

The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.

BRIEF DESCRIPTION OF SEVERAL VIEWS OF THE DRAWING(S)

The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:

FIG. 1 is an isometric view of a reclining wheelchair apparatus according to an embodiment of the disclosure.

FIG. 2 is an isometric view of an embodiment of the disclosure.

DETAILED DESCRIPTION OF THE INVENTION

With reference now to the drawings, and in particular to FIGS. 1 through 5 thereof, a new wheelchair device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 5, the reclining wheelchair apparatus 10 generally comprises a chair base frame 12 having a base front side 14, a base back side 16, a base left side 18, a base right side 20, a base top side 22, and a base bottom side 24. A plurality of wheels 26 is coupled to the chair base frame 12. The plurality of wheels 26 may include a pair of fixed back wheels 28 extending above the base top side 22 and a pair of rotating front wheels 29 coupled to the base bottom side 24 adjacent the base front side 14.

A seat bottom 30 is coupled to the base top side 22. The seat bottom 30 may extend from the base left side 18 to the base right side 20 and may be foldable to allow the chair base frame 12 to fold. A seat bottom extension 31 may be slidably engageable with the seat bottom 30 and extends as shown in FIG. 2. A pair of wheel brakes 32 may be coupled to the base left side 18 and the base right side 20 and in operational communication with the pair of fixed back wheels 28 to prevent the apparatus 10 from moving when desired. A pair of arm rests 34 may be coupled to the base top side 22 adjacent the base left side 18 and the base right side 20, and a pair of foot rests 36 may be pivotably coupled to the base left side 18 and the base right side 20 and positionable to extend past the base front side 14.

A pair of pivot brackets 38 is coupled to the chair base frame 12. Each pivot bracket 38 has a bracket plate 40 and a pivot rod 42 coupled to the bracket plate 40. The pivot rod 42 is pivotably coupled to the base top side 22 adjacent the base back side 16. Each bracket plate 40 may have a planar back edge 44.

A chair back 46 is coupled to the pair of pivot brackets 38. The chair back 46 includes a pair of back frames 48 coupled to the pair of pivot brackets 38 and a back sling 50 coupled between the pair of back frames 48. Each back frame 48 may be telescopable. The back sling 50 may also be foldable to allow the chair base frame 12 to fold. Each back frame 48 may include a bent handle portion 52 with an ergonomic grip 54. The chair back 46 moves between an upright position shown in FIG. 3 and a reclined position shown in FIG. 4.

A pair of bracket supports 56 is coupled to the base back side 16 adjacent the base top side 22. The pair of pivot brackets 38 rests on the pair of bracket supports 56 when the chair back 46 is in the reclined position. Each bracket support 56 may form an angle with the base back side 16 between 90°-115° to provide a fully flat or nearly flat transition between the seat bottom 30 and the back sling 50.

A pair of locking pins 58 is coupled to the pair of pivot brackets 38. Each locking pin 58 comprises a cylindrical pin housing 60 coupled to the respective pivot bracket 38 and a pull pin 62 slidably coupled through a pin aperture 64 of the pin housing 60. The pull pin 62 is selectively engageable with the base top side 22 to secure the chair back 46 in the upright position. The pull pin 62 may include a spring 64 coupled within the pin aperture 64 to bias the pull pin 62 towards an engaged position with the base top side 22 to prevent accidental disengagement. The pull pin 62 may be L-shaped and has a padded horizontal grip portion 66 for easy manipulation.

In use, the chair back 46 in the upright position allows the apparatus 10 to be used as a traditional wheelchair. When desired, the pair of locking pins 58 are disengaged by pulling up on the horizontal grip portion 66 to allow the pivot brackets 38 to pivot until they rest on the pair of bracket supports 56 and the chair back is in the reclined position. The user may then lie down fully in order to be cared for or to rest.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
