Description
BACKGROUND OF THE INVENTION
This invention relates to wheelchair head or back supports and more
particularly to a head or back support which can be adjusted to the
individual patient's comfort without obstructing the normal use of
the wheelchair.
Collapsible wheelchairs provide some fixed back support for the
occupants. The satisfactory use of such chairs is limited, however,
by reason of the fact that adequate head and back support is not
provided for the majority of persons required to use such chairs.
In the normal use of the wheelchair, an infirm occupant who tires
easily cannot maintain himself erect in a comfortable sitting
position.
There are currently available devices for attachment to the
wheelchair which provide some support for the occupant. An example
of such device is U.S. Pat. No. 3,497,259 issued Feb. 24, 1970.
The prior art devices are not entirely satisfactory. The use of
such devices would very often limit the overall usefulness of the
wheelchair. Adjustments of the supporting devices would have to be
made to compensate for various wheelchair widths. Quite often,
complex clamping means and adjustment means were provided.
Accordingly, it is an object of this invention to provide a head
and back support for wheelchairs which can be attached to all
wheelchairs and can be adjusted to the individual patient's comfort
without obstructing the normal use of the wheelchair.
A further object of this invention is to provide a head and back
support for wheelchairs having a novel pivoting means which
automatically compensates for various wheelchair widths and which
will permit easy removal of the supporting device.
A still further object of this invention is to provide a wheelchair
head or back support which is fully adjustable in the horizontal,
vertical and angular directions as required to provide custom
adjustments to suit individual patient needs.
SUMMARY OF THE INVENTION
This invention provides an improved head or back support for
wheelchairs which can be attached to wheelchairs and can be
adjusted to the individual patient's comfort without obstructing
the normal use of the wheelchair. The combination support is
securedly attached on each of the vertical supports on the back of
the wheelchair. Horizontal arms are pivotally mounted to the
securing means and are pivotally held at the center by a vertical
rod carrying bracket body. The headrest and backrest are each
adjustably mounted on either side of the bracket body.
Other objects, details, uses and advantages of this invention will
become apparent as the following description of an exemplary
embodiment thereof presented in the accompanying drawings
proceeds.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying drawings show a present exemplary embodiment of
this invention in which:
FIG. 1 is a perspective view illustrating the head or back support
mounted on a wheel chair; and
FIG. 2 is an exploded perspective view of the support.
DESCRIPTION OF ILLUSTRATED EMBODIMENTS
Reference is now made to the drawings which illustrate one
exemplary embodiment of the improved head or back support of this
invention, which is designated generally by the reference numeral
10. The combination support 10 is shown in FIG. 1 attached to a
wheelchair 12 shown in phantom lines.
The combination support 10 is clamped to the vertical supports 14
of the wheelchair by identical brackets 16 and 18. The brackets are
formed with a curved flange portion which engages the support 14.
The brackets 16 and 18 are secured to the vertical supports 14 by
suitable means such as threaded knobs 20 and 22, respectively,
which urge plates 24 and 26 into clamping engagement with the
supports 14. The brackets 16 and 18 are provided with tubular
portions 28 and 30. To insure proper alignment of the combination
support 10, it is necessary that the brackets 16 and 18 be placed
at the same vertical height on the supports 14.
One end of each horizontal arm 32 and 34 is slidably inserted in
the tubular portion 28 and 30 of the brackets 16 and 18. A bracket
body 36, having three bores therethrough, is placed over the
vertical extending ends of the horizontal arms 32 and 34. The
bracket body 36 is secured in place by any suitable means such as
four set screws 38 which are tightened to engage the vertical ends
of the arms 32 and 34. The pivoting action of the arms 32 and 34 in
the tubular portions 28 and 30 permits the combination support 10
to be mounted on any wheelchair since the pivoting effect
automatically compensates for various wheelchair widths.
The vertical support rod 40 is inserted through the central bore of
bracket body 36 and is secured in place by any suitable knob or
thumb screw 42. The head support, designated generally as 44 and
the back support, designated generally as 46, are clamped to the
vertical rod 40 by identical clamping means 48 and 50, only one of
which will be described in detail hereinbelow.
The headrest 44 comprises a pair of suitable cushions 52 and 54
which are secured to a plate 56 by any suitable means such as a
plurality of screws 58. The plate 56 is secured to an abutment 60
by any suitable means such as a cap screw and lock washer 62 and
64, respectively. The abutment 60 forms one end of a horizontal
supporting rod 66. The rod 66 is slidably inserted through a bore
68 formed in the end of clamp bolt 70. The clamp bolt 70 protrudes
through apertures in clamp plate 72 and clamp body 74. A threaded
knob or handle or the like 76 engages the end of clamp bolt 70. The
clamp body 74 is formed with a channel or groove 78 therethrough
which receives the rod 40 therein. The rod 40 is formed with a
portion 80 thereby providing a flat portion against which the inner
surface of clamp plate 72 abuts. Thus, when the clamping plate 72
and clamping body 74 are secured to the rod 40, rotation of the
clamping means 48 and hence the headrest 44 is prevented due to the
engagement of the clamping plate 72 with the flattened portion 80.
When the head support 44 is mounted to the clamping means 48 and
the clamping means 48 mounted on the rod 40, it can be seen that
the head support 44 can be adjusted in the vertical, horizontal and
angular (in the vertical plane) directions. When the desired
position of the head support 44 has been obtained, the handle 76 is
rotated to secure the clamping means in the desired position.
The back support 46 comprises a back cushion 82 which is secured to
a back plate 84 in a manner similar to that hereinabove described
relative to the head support 44. The clamping means 50 is identical
to the clamping means 48 described hereinabove and need not be
described again. It being sufficient to note that the clamping
means 50 is secured to that portion of the rod 40 which extends
below the bracket body 36. The back support is similarly adjustable
to provide the necessary support to the individual patient.
Once the head support 44 and the back support 46 have been adjusted
to the desired position, the assembly may be removed from the
wheelchair without loss of the desired adjustments. It is only
necessary to grasp the body bracket 36 and/or horizontal arms 32
and 34 in lifting the unit straight up until the ends of the
horizontal arms 32 and 34 are out of the tubular portions 28 and
30. To reinstall the unit, one simply slides the ends of the
horizontal arms back into the tubular portions 28 and 30.
It can be seen that this unit automatically compensates for various
wheelchair widths and when installed does not interfere with normal
wheelchair usage, yet provides the necessary support for the
patient. This invention provides a head or back support for a wheel
chair which is of simple and economical construction, is easy to
adjust, i.e., only one knob each provides all the necessary
clamping for the headrest and backrest adjustments.
While a present exemplary embodiment of this invention has been
illustrated and described, it will be recognized that this
invention may be otherwise variously embodied and practiced by
those skilled in the art.
