ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention is related to an improved hanging hook. Prior to assembly of the hanging hook, the surfaces of the components can be respectively plated with non-metal colors. Then the components are assembled so as to achieve a beautiful and colorful appearance of the hanging hook. The hanging hook can be easy, quick and accurately operated to hook an article.
FIG. 1
shows a conventional hanging hook
10
having a hook section
11
formed with an internal cavity. A spring and a latch block
12
are received in the cavity and pivotally connected with the hook section
11
by a shaft pin
13
. The latch block
12
can be pressed inward. A ring body
14
is pivotally disposed on the hook section
11
. For presenting colorful appearance of the hanging hook
10
, prior to assembly, the surfaces of the components are respectively plated with non-metal colors. Then the components are assembled. However, when the pivot pin
13
is passed through the hook section
11
and the latch block
12
, the paint of the periphery of the pivot section A is subject to detachment so that the appearance of the hanging hook
10
will be deteriorated. In the case that metallic materials with different colors are plated on the surfaces of the components, since the metallic materials only have a few fixed colors so that the appearance will be monotonous.
FIG. 2
shows another type of conventional hanging hook
20
having a hook section
21
. The upper portion of the hook section
21
is formed with a cavity in which a spring and a T-shaped latch body
22
are received. The T-shaped latch body
22
can be pressed inward. A ring body
23
is pivotally disposed on the hook section
21
. For presenting colorful appearance of the hanging hook
20
, prior to assembly, the surfaces of the components are respectively plated with non-metal colors. Then the components are assembled. However, when assembled, it is necessary to first bias the end section of the hook section
21
with a hand and then install the spring and the T-shaped latch body
22
. The paint of the biased section B tends to detach therefrom. Therefore, the appearance of the hanging hook
20
will be deteriorated. In the case that metallic materials with different colors are plated on the surfaces of the components, since the metallic materials only have a few fixed colors so that the appearance will be monotonous.
FIG. 3
shows still another type of Conventional hanging hook
30
having a hook section
31
, a spring
32
, a press button
33
, a latch member
34
and a ring body
35
. The hook section
31
has a stem body
311
. A lower end of the stem body
311
is formed with an annular stop section
312
. One side of the stop section
312
is cut with a restricting split
313
. The other side is provided with a downward extending a hook
314
. The stem body
311
is formed with a socket
315
above the split
313
. The upper portion of the stem body is formed with an annular groove
316
for pivotally connecting with the ring body
35
. The press button
33
is a two-step cylindrical body having an outer large diameter section and an inner small diameter section. A dome section
331
is disposed at end face of the large diameter section. The latch member
34
is a hoop member fitted on the stem body
311
of the hook section
31
. One side of the latch member
34
is formed with a downward extending latch arm
342
. The periphery of the latch member
34
is formed with a through hole
341
above the latch arm
342
. When assembled, as shown in
FIG. 4
, the spring
32
is first placed into the socket
315
of the hook section
31
and the press button
33
is pressed into the socket
315
to resiliently compress the spring
32
. The dome section
331
of the press button
33
protrudes out of the socket
315
. Then, the latch member
34
is fitted onto the stem body
311
of the hook section
31
with the latch arm
342
fitted into the restricting split
313
of the hook section
31
. At this time, the dome section
331
is engaged in the through hole
341
of the latch member
34
. The bottom face of the latch member
34
is stopped by the stop section
312
of the hook section
31
. The end of the latch arm
342
is leant on the end of the hook
314
of the hook section
31
. Then, the ring body
35
is pivotally fitted in the annular groove
316
. In use, a user needs to press the dome section
311
to compress the spring
32
and disengage the dome section
331
from the through hole
341
of the latch member
34
(as shown in
FIG. 4
). Then the latch member
34
is pushed upward to slide the latch arm
342
out of the restricting split
313
of the hook section
31
.
At this time, the press button
33
is pressed against the latch arm
342
and the hook
314
can hook an article. Then, the latch member
34
is pushed back downward to again insert the latch arm
342
into the restricting split
313
. Under such circumstance, the dome section
331
is again engaged in the through hole
341
of the latch member
34
with the end of the latch arm
342
again leant against the end of the hook
314
. Such operation is quite troublesome. Moreover, when pressing the dome section
331
with a finger, it often takes place that the dome section
331
fails to disengage from the through hole
341
and remains engaged therein. Therefore, the latch member
34
can be hardly successfully pushed out. This leads to inconvenience in use.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide an improved hanging hook in which it is unnecessary to use any pivot pin for pivotally connecting the components or bias the hook section. Therefore, prior to assembly, the surfaces of the components can be respectively plated with non-metal colors. Then the components are assembled. After assembled, the paint is not subject to detachment so that the appearance of the hanging hook will remain beautiful and colorful.
It is a further object of the present invention to provide the above hanging hook in which in use, by means of only one time of operation, the latch member is directly upward pushed with a finger, permitting the hook of the hook section to hook a desired article. When the latch member is released, the spring is restored so that the article is encompassed. Such operation is easy, quick and accurate.
The present invention can be best understood through the following description and accompanying drawings wherein:
