Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an improved skate body with an easy-to-replace brake block.
2. Description of the Related Art
FIG. 7

1
that is integrally formed and has a single color, which cannot attract buyers. A brake block
3
is attached by a bolt
2
and a nut
5
to a brake seat
4
located on a front end of the skate body
1
. It was found that the bolt and nut engagement tends to loosen and/or rust after a period of time, which may lead to an accident.
It is the primary object of the present invention to provide an improved skate body that includes two body portions for providing a variety of combinations in colors and configurations. In addition, the skate body includes a brake block that can be removed easily and quickly when it is worn out, and a new one can be attached to the skate body easily and quickly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 1 and 2
, a skate body in accordance with the present invention generally includes a first body portion
10
, a second body portion
20
, and a brake means
30
. The first body portion
10
is substantially U-shape and includes two lateral sides
15
and two ends each having a connecting portion
11
formed thereon. Each connecting portion
11
includes an opening
12
in a center thereof. A plurality of holes
13
are defined in the connecting portion
11
for connection with a boot
62
(
FIG. 5
) or the like. A slot
14
is defined in one of the connecting portions
11
. The lateral sides
15
of the first body portion
10
include a plurality of aligned holes
16
, which will be described later. A space
17
is defined between the lateral sides
15
.
The second body portion
20
is substantially U-shape and includes two lateral sides
24
and two ends each having an inverted U-shape connecting portion
21
formed thereon, wherein each of two limbs (not labeled) of the connecting portion
21
is integrally formed with an associated lateral side
24
. The lateral sides
24
include a space
28
therebetween and a plurality of pairs of aligned holes
25
for mounting wheels
60
(FIG.
5
). The lateral sides
24
further include a pair of aligned holes
27
in front ends
26
thereof. Each connecting portion
21
includes a hole
22
for connection with the boot
62
(FIG.
5
).
The brake means
30
includes a brake seat
31
that is mounted to the front end of the second body portion
20
by a screw
40
that extends through a transverse hole
35
in the brake seat
31
and engages with a nut
41
. The brake seat
31
includes an engaging portion
33
with an engaging piece
34
for releasably engaging with the slot
14
in the first body portion
10
. The brake seat
31
further includes a resilient hook member
37
and a substantially U-shape rib
38
formed on an inner wall thereof. The brake seat
31
further includes a slot
36
that communicates an interior of the brake seat
31
with outside, as best shown in FIG.
3
.
The brake means
30
further includes a brake block
32
releasably attached to the brake seat
31
. The brake block
32
includes an engaging groove
39
for releasable engagement with the rib
38
of the brake seat
31
. The brake block
32
further includes a retaining piece
391
for releasable engagement with the resilient hook member
37
of the brake seat
31
, as best shown in FIG.
3
.
In assembly, the second body portion
20
is inserted into the space
17
of the first body portion
10
with the holes
16
in the first body portion
10
aligned with holes
23
in the second body portion
20
and with an upper portion of each connecting portion
21
of the second body portion
20
engaged in the opening
12
of an associated connecting portion
11
of the first body portion
10
. Screws
18
are extended through the holes
16
and
23
and engaged with nuts
19
to thereby secure the first and second body portions
10
and
20
together. The brake seat
31
is attached to the front end of the second body portion
20
by the screw
40
with the engaging piece
34
engaged with the slot
14
of the first body portion
10
. The brake block
32
is inserted into an interior of the brake seat
31
with the engaging groove
39
engaged with the rib
38
of the brake seat
31
and with the retaining piece
391
engaged with the resilient hook member
37
of the brake seat
31
, as best shown in FIG.
3
.
Referring to
FIG. 4
, when the brake block
32
is worn out, the user may extend a tool (such as a screwdriver
50
) through the slot
36
into the interior of the brake seat
31
until the blade of the screwdriver
50
is in contact with the resilient hook member
37
. Then, the user applies a force to the handle of the screwdriver
50
to move the resilient hook member
37
away from the brake block
32
. The engaging piece
391
of the brake block
32
will be disengaged from the resilient hook member
37
, and the engaging groove
39
will be disengaged from the rib
38
of the brake seat
31
. Thus, the brake block
32
is removed, and a new one can be mounted to the brake seat
31
subsequently.
Configurations of both of the first and second body portions
10
and
20
can be modified according to the market need.
FIGS. 5 and 6
illustrate skate bodies having slight differences in middle areas of the first body portions
10
.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed.
