Abstract
A fast-dismountable covering panel for mounting on a chassis of an electric cart is provided. The covering panel includes a front round opening and a rearward opened elongate opening opposite to the round opening. The elongate opening is adapted to engage with a handlebar stem upward extended from a front end of the chassis. A very narrow slit is provided along a centerline of the covering panel to extend between the round opening and the elongate opening, allowing the covering panel to be elastically stretched apart at the elongate opening along the slit for the handlebar stem to move forward along the slit into the round opening and causing the covering panel to cover and be screwed to a top of the chassis. A gasket is removably engaged with the slit to seal the same. Footrest panel, mat fixing strips and mat may be detachably connected to the covering panel and the covering panel may be mounted onto the chassis after the latter has been fully assembled and passed quality inspection. When necessary, the covering panel may also be quickly dismounted from the chassis by stretching it apart along the slit.
Description
FIELD OF THE INVENTION
The present invention relates to a fast-dismountable covering panel for an electric cart, and more particularly to an electric cart covering panel having a longitudinal slit for the covering panel to be elastically stretched apart along the slit and thereby facilitate quick mounting and dismounting of the covering panel onto and from the electric cart.
BACKGROUND OF THE INVENTION
Cars have become very important traffic means in the modern society, particular in cities. With the increasing requirement for environmental protection, there is also developed a four-wheel electric cart that not only enables reduced environmental pollution but also has reduced dimensions and weight compared with the common cars and motorcycles. Such electric cart can be easily operated and is therefore widely welcome and employed by the invalid and the aged to conveniently assist them in moving usually within a short distance.
For the electric cart to have various and beautiful appearance, differently designed and colored covering panels are provided for mounting onto a top of a chassis of the electric cart.
FIGS. 13 and 14
illustrate a conventional electric cart A, a covering panel A
1
and a chassis A
2
of which are so designed that they must be assembled together in the process of manufacturing the electric cart. And, a handlebar A
3
of the electric cart and a decorative cover A
4
thereof could be connected to related mechanisms in the chassis only when the covering panel A
1
has been assembled to the chassis. Similarly, other parts, such as brake cable, electric control wiring and the like having close connection with the handlebar A
3
, could not be sequentially installed along with the handlebar A
3
until the covering panel has been mounted onto the chassis. As a result, the manufacture and assembling of the electric cart A is difficult and troublesome and requires a lot of time and labor.
Moreover, the conventional electric cart A is sent for quality inspection in a completely assembled state. That is, the electric cart A is inspected for quality with the covering panel A
1
fully mounted onto the chassis A
2
and the power mechanism, electric wiring, braking mechanism thereof completely installed in the chassis A
2
. The fully assembled electric cart A has a considerable weight that forms a hindrance in hoisting or sideward turning the cart for the purpose of quality inspection. The covering panel A
1
tends to be scraped or otherwise damaged during such quality inspection. In the event the chassis A
2
or other mechanism or wiring installed in the chassis is found unqualified in the quality inspection and must be dismounted and replaced, it would be inevitable to sequentially dismount the decorative cover A
4
, the handlebar A
3
and the covering panel A
1
from the chassis A
2
before such internal mechanism or wiring can be checked, repaired or replaced. And, the covering panel A
1
, the handlebar A
3
and the decorative cover A
4
must be sequentially assembled to the chassis A
2
again when the unqualified parts are repaired or replaced. The troublesome mounting and dismounting of the covering panel A
1
to the chassis A
2
obviously increases the manufacturing costs of the electric cart A.
Another problem with the conventional electric cart A is the covering panel A
1
and the chassis A
2
that are assembled together during the production of the electric cart A would disadvantageously necessitate time and labor consumed replacement of the covering panel in the above-mentioned troublesome procedures when a buyer prefers to a covering panel of different color or style. This obviously does not meet the requirement of efficiency in the industrial field.
Moreover, it is very possible that a second time mistake in the installation of the related brake cable and/or electric wiring occurs when the decorative cover A
4
, the handlebar A
3
and the covering panel A
1
are repeatedly dismounted and mounted. This would also form a factor disadvantageously affecting the quality of the electric cart A.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a fast-dismountable covering panel for easily mounting onto and dismounting from a chassis of an electric cart.
In one aspect of the present invention, the covering panel is provided along a centerline with a slit, so that the covering panel is elastically stretchable apart along the slit for conveniently covering it onto the chassis after the chassis and the related parts and wirings have been fully assembled and inspected for quality. Time and labor needed for manufacturing and QC inspection of the electric cart can therefore be largely reduced.
In another aspect of the present invention, the covering panel is provided along a centerline with a slit and at a front end of the slit with a round opening for a handlebar stem of the electric cart to move through the elastically stretched slit and engage into the round opening. That is, the handlebar stem can be assembled to the chassis before the covering panel is mounted onto the chassis, and any possible dismounting of the covering panel could be performed independently of the handlebar.
In a still another aspect of the present invention, the covering panel is provided along a centerline with a slit that allows the covering panel to be elastically stretched apart along the slit to enable easy and fast dismounting and replacement of the covering panel with another one to freely give the electric cart different color or style to attract more buyers.
To achieve the above and other objects, the fast-dismountable covering panel for an electric cart according to the present invention includes a front round opening and a rearward opened elongate opening opposite to the round opening. The elongate opening is adapted to engage with a handlebar stem upward extended from a front end of the chassis. A very narrow slit is provided along a centerline of the covering panel to extend between the round opening and the elongate opening, allowing the covering panel to be elastically stretched apart at the elongate opening along the slit for the handlebar stem to move forward along the slit into the round opening and causing the covering panel to cover and be screwed to a top of the chassis. A gasket is removably engaged with the slit to seal the same. Footrest panel, mat fixing strips and mat may be detachably connected to the covering panel and the covering panel may be mounted onto the chassis after the latter has been fully assembled and passed quality inspection. When necessary, the covering panel may also be quickly dismounted from the chassis by stretching it apart along the slit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to
FIG. 1
that shows an electric cart having a fast-dismountable covering panel
100
according to an embodiment of the present invention and a chassis
200
onto which the fast-dismountable covering panel
100
is mounted. For the purpose of clarity and simplicity, the fast-dismountable covering panel
100
shall be referred to as the covering panel
100
hereinafter. The covering panel
100
may be differently designed. In the following description, the covering panel
100
is designed for mounting on to a chassis
200
for a four-wheel electric cart. However, it is understood that the covering panel
100
illustrated in the accompanying drawings is only a non-limiting example of the present invention.
As shown, the covering panel
100
includes a raised front portion that is provided at a top central area with a round opening
10
for engaging with a handlebar stem
210
of the chassis
200
. A firm engagement of the handlebar stem
210
with the round opening
10
is achieved via a coupler
20
.
FIG. 2
is an enlarged sectional view of the coupler
20
. As shown, the coupler
20
is a hollow member having a top hole
21
through which the handlebar stem
210
extends. The coupler
20
is mounted around the handlebar stem
210
during assembling of the chassis
200
. At least one annular groove
22
is provided around a lower outer periphery of the coupler
20
for fitly receiving a circular edge of the round opening
10
in the annular groove
22
.
The covering panel
100
also includes a substantially flat rear portion that rearward extends from a lower rear end of the raised front portion. A part of the flat rear portion of the covering panel
100
opposite to the round opening
10
is cut away to form a rearward opened elongate opening
40
. The elongate opening
40
has shape and dimensions corresponding to that of a main post
220
of the chassis
200
for supporting a seat
230
thereon. A very narrow slit
30
is provided along a centerline of the covering panel
100
to extend between the round opening
10
and the elongate opening
40
. With the slit
30
, portions of the covering panel
100
at two sides of the slit
30
can be flexibly outward separated apart to some extent. A plurality of mounting holes
50
and
60
are provided on the rear and the front portions, respectively, of the covering panel
100
to facilitate connection of the covering panel
100
to the chassis
200
and other components to the covering panel
100
with screws or other fastening means extended through the mounting holes
50
,
60
.
Please refer to
FIGS. 3 and 4
. To mount the covering panel
100
onto the chassis
200
, first align the elongate opening
40
on the covering panel
100
with the handlebar stem
210
at the front of the chassis
200
and move the covering panel
100
in a direction as indicated by the broken arrows in
FIG. 3
, so that the handlebar stem
210
is located in the elongate opening
40
. Thereafter, apply a suitable force to elastically separate the portions of the covering panel
100
at two sides of the slit
30
apart, so that the covering panel is allowed to move further for the handlebar stem
210
to locate in the round opening
10
. At this point, release the covering panel
100
and the same would automatically elastically return to its original shape to cover most part of the chassis
200
in front of two rear wheels of the electric cart with the circular edge of the round opening
10
engaging into the annular groove
22
of the coupler
20
and the main post
220
locating in the elongate opening
40
, as shown in FIG.
4
. The covering panel
100
and the handlebar stem
210
are thereby quickly and firmly associated with each other.
After the covering panel
100
is primarily assembled to the chassis
200
as illustrated in
FIGS. 3 and 4
, a gasket
70
is set into the slit
30
to seal the same and to ensure integrity of the appearance and fully sealed structure of the covering panel
100
.
FIG. 5
shows the manner of mounting the gasket
70
onto the covering panel
100
. The gasket
70
may be of any shape. In the illustrated embodiment of the present invention, the gasket
70
has an I-shaped cross section to define at two sides two longitudinal grooves
71
,
72
, as shown in FIG.
6
. The gasket
70
may be set in the slit
30
by elastically separating the covering panel
100
apart along the slit
30
, such that two edges of the covering panel
100
at two sides of the slit
30
fitly engage into the two longitudinal grooves
71
,
72
of the gasket
70
, as shown in FIG.
7
. When the covering panel
100
is allowed to elastically return to its original shape, the gasket
70
will completely seal the slit
30
. After the gasket
70
has been fitted in the slit
30
, the covering panel
100
is fixedly connected to the chassis
200
by aligning mounting holes
50
on the flat rear portion of the covering panel
100
with holes (not shown) on the chassis and threading, for example, screws D into the aligned mounting holes, as shown in FIG.
5
.
After the covering panel
100
is fixed to the chassis
200
with screws D, a number of mat fixing strips
80
may be connected to the covering panel
100
at positions in front of the seat
230
, as shown in
FIGS. 8 and 9
. The mat fixing strips
80
may be of any shape and style. In the illustrated embodiment of the present invention, the mat fixing strips
80
are hook and loop connecting strips. The mat fixing strips
80
may be connected to the covering panel
100
via many different means, such as adhesive, nails, screws or the like.
The covering panel
100
may also be decorated with other materials. In
FIGS. 10 and 11
, a footrest panel
90
is attached to the raised front portion of the covering panel
100
in front of the seat
230
to protect the covering panel
100
from easily wearing off due to frequent frictional contact of a driver's feet with the covering panel
100
. The footrest panel
90
may be of any shape so long as it well matches with the color and/or shape of the covering panel
100
. To connect the footrest panel
90
to the covering panel
100
, the footrest panel
90
may be provided at a backside with a plurality of studs
91
for engaging with the mounting holes
60
provided on the covering panel
100
.
Moreover, a mat
300
may be detachably connected to the covering panel
100
via the mat fixing strips
80
to cover the portion of the covering panel
100
directly in front of the seat
230
.
The following are some advantages of the fast-dismountable covering panel of the present invention:
1. The covering panel
100
and the chassis
200
may be separately fabricated and assembled that allows the manufacture, assembling and quality control of the electric cart to be performed at largely reduced time and labor.
2. The covering panel
100
needs not to be assembled to the chassis
200
until the chassis
200
, the handlebar stem
210
and all other related components, such as brake cable, electric control wirings, etc., have been assembled together and checked with respect to overall quality of the electric cart. There is no need to repeatedly mount and dismount the handlebar stem
210
, the brake cable or the electric control wirings during QC process of the electric cart. Second time mistakes possibly occurring in re-assembling dismounted components can therefore be avoided.
3. Since the covering panel
100
may be elastically separated along the slit
30
and quickly dismounted from the chassis
200
, replacement of an original covering panel
100
with other covering panel
100
of different color and style can be easily performed to meet customer's satisfaction. This gives manufacturers and consumers more flexibility and choices in producing and purchasing the electric carts.
The prevent invention as illustrated in
FIGS. 1 through 12
provides a simplest way to produce the electric cart at largely reduced time, labor and other costs without largely changing the structure of the electric cart. The fast-dismountable covering panel of the present invention for the electric cart also minimizes the chances of second time mistakes occurred in re-assembling components of the cart dismounted during quality inspections.
The present invention has been described with a preferred embodiment thereof and it is understood that many changes and modifications in the described embodiment can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
