Wheel chair description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a battery compartment, and more
particularly to a battery compartment for a motorized wheel chair.
The battery compartment has two halves each pivotally connected
with one another and having a stop formed on a side thereof so as
to prevent excess pivotal movement of the other.
2. Description of Related Art
With reference to FIG. 4, a conventional motorized wheel chair
(60) is shown. The motorized wheel chair (60) has two brackets (61)
mounted on opposite sides of the motorized wheel chair (60). The
two brackets (61) are connected with connection rods (62) in such
a manner that the motorized wheel chair (60) is able to be folded.
A battery compartment (63) is formed between two rear wheels (64)
so as to receive therein batteries. The batteries are able to provide
electricity to power the motor in the motorized wheel chair (60).
When the motorized wheel chair (60) is not in use and to be folded,
the batteries must be removed and stored elsewhere.
Nowadays, there are different ways of receiving the batteries in
the motorized wheel chair. With reference to FIG. 5, a conventional
method for receiving batteries is shown. The bracket (71) of the
motorized wheel chair (70) has two fixing rods (72) extending oppositely
from an inner side of the bracket (71) of the motorized wheel chair
(70) toward the battery compartment (700). A support (73) is provided
on distal ends of the two fixing rods (72) to support the battery
(74). A reinforced plate (75) is provided to connect two supports
(73) so as to reinforce the strength of the supports (73) when having
the batteries (74) thereon.
When the motorized wheel chair (70) is not in use, the bolt (76)
has to be removed to disassemble the connection between the reinforced
plate (75) and the supports (73) so that the batteries (74) are
able to be removed for storage and the motorized wheel chair (70)
is able to be folded as shown in FIG. 6.
This kind of motorized wheel chair (70) requires constant removal
of the batteries (74) from the bracket (71) especially when the
motorized wheel chair (70) is to be folded, such that not only the
assembly and disassembly of the reinforced plate (75) are time consuming,
but also the mounting and dismounting of the batteries (74) are
labor intensive and therefore exhaustive. This may prove to be troublesome
and expensive as the wheel chair user will rely on another person,
probably a professional carer, whose time will be used excessively
in this operation.
A further disadvantage of the motorized wheel chair is that the
parts for securing the overall integrity are easily lost especially
when disassembly of the motorized wheel chair is a constant routine.
To overcome the shortcomings, the present invention intends to
provide an improved battery compartment to mitigate or obviate the
aforementioned problems.
SUMMARY OF THE INVENTION
The primary objective of the invention is to provide an improved
battery compartment having two halves. Each half is securely connected
to an inner side of the bracket of the motorized wheel chair so
that the two halves encounter each other to form a support for holding
a battery thereon.
Another objective of the invention is to provide a stop on a side
of each of the halves so that excess pivotal movement of the two
halves is prevented when each of the halves engages with the stop.
Other objects, advantages and novel features of the invention will
become more apparent from the following detailed description when
taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
With reference to FIG. 1, the battery compartment (20) has a first
securing bracket (21), a first frame (22), a second frame (23) and
a second securing bracket (24).
The first securing bracket (21) is L shaped and has a pair of sleeves
(211) firmly formed on a horizontal plate of the first securing
bracket (21). Because the second securing bracket (24) has the same
structure as that of the first securing bracket (21), the description
to the second securing bracket (24) is omitted but will be incorporated
hereinafter.
The first frame (22) is substantially U shaped and has a hole (221)
defined in both distal ends of the first frame (22), a stop (222)
formed on a side face adjacent to each of the distal ends of the
first frame (22) and extending toward each other, and two first
extensions (223) formed on an outer face at a bottom of the first
frame (22) and respectively having a through hole (224) defined
to correspond to one of the sleeves (211) of the first securing
bracket (21).
The second frame (23) is also substantially U shaped and reversed
to the first frame (22). The second frame (23) has two apertures
(231) respectively defined at a distal end thereof to correspond
to the through hole (221) of the first frame (22) and two second
extensions (233) formed on an outer face at a bottom of the second
frame (23) and respectively having a through hole (234) defined
to correspond to one of two sleeves (241) of the second securing
bracket (24).
With reference to FIG. 2 and still taking FIG. 1 into consideration,
when the battery compartment of the present invention is to be assembled,
the first and second securing brackets (21,24) are adapted to be
securely connected to two side brackets (11) of the motorized wheel
chair (10). After the assembly of the first and second securing
brackets (21,24), the first and second frames (22,23) are respectively
and pivotally connected to the sleeves (211,241) of the first and
second securing brackets (21,24). That is, the two through holes
(224,234) of the two extensions (223,233) of the first and second
frame (22,23) are aligned with the sleeves (211,241) and then a
securing bolt (26) is inserted into the aligned through holes (224,234)
and the sleeves (211,241) to secure the pivotal engagement of the
extensions (223,233) to the sleeves (211,241). Thereafter, the first
and the second frames (22,23) are pivotable relative to the first
securing bracket (21) and the second securing bracket (24) respectively.
Then, the through holes (221) of the first frame (22) align with
the apertures (231) of the second frame (23) such that a bolt and
nut combination (25) is able to secure the pivotal engagement between
distal ends of the first and second frames (22,23). After the battery
compartment (20) of the present invention is assembled, it is to
be noted that the stops (222) formed on the distal ends of the first
frame (23) are able to prevent excessive pivotal movement between
the first and second frames (22,23) when the battery compartment
(20) is extended.
With reference to FIG. 3, when the motorized wheel chair is to
be folded, unlike in the prior art, the user will not have to disassemble
the battery compartment (20). The user only needs to remove the
battery (not shown) for storage elsewhere and then brings together
the first and second frames (22,23) so that the motorized wheel
chair is able to be folded.
It is concluded that the battery compartment of the present invention
requires no disassembly process for folding the motorized wheel
chair so that there is no worry about losing parts. Moreover, the
structure of the battery compartment is simple so that no major
alteration is required and therefore, the cost is low.
Even though numerous characteristics and advantages of the present
invention have been set forth in the foregoing description, together
with details of the structure and function of the invention, the
disclosure is illustrative only, and changes may be made in detail,
especially in matters of shape, size, and arrangement of parts within
the principles of the invention to the fill extent indicated by
the broad general meaning of the terms in which the appended claims
are expressed.
