ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a loop-pin attaching device which can shot a loop-pin which can bind clothes, socks, or the like or which can attach tags such as brand labels, price tags, material description, instructions or the like to a good by inserting one end portion of an un-looped of the loop-pin into a part of a good and after that by coupling both end portions thereof with each other so as to form a loop.
BACKGROUND OF THE INVENTION
In general, in order to bind clothes, daily small articles, sandals, shoes or the like or to efficiently attach brand labels, price tags or the like to relevant products, various kinds of loop-pins and the loop-pin attaching devices have been used in the past.
A specific configuration of one embodiment of a conventional loop-pin
10
is explained with reference to
FIGS. 7
to
11
.
As shown in
FIG. 7
, the loop-pin
10
comprises a flexible filament section
12
, an insertion head section
13
equipped with a suitable engagement section
16
located at one end of the filament section
12
, and a socket section
15
equipped with a hole
14
for irreversibly passing the insertion head section
13
located at the other end of the filament section
12
, wherein the hole
14
being provided with a pair of blade section
17
,
17
′ inside thereof and which can engage with the engagement section
16
of the insertion head section
13
.
And further, this conventional loop-pin
10
, for example, is made of a synthetic resin material such as ordinal nylon resin, polyester resin or the like and also the insertion head section
13
, the socket section
15
and the filament section
12
thereof being integrally molded into one body.
In the above-mentioned embodiment, as shown in
FIG. 8
, when a desired good, for example a bag
200
, is a target good to which a tag should be attached, after the filament section
12
is inserted into a hole
410
previously provided on the tag
400
, such as a label or the like, the socket section
15
and a part of the filament section
12
, for example, are passed through a space formed between a gripping portion
300
of the bag
200
and a surface of main body of the bag
200
and then the insertion head section
15
is inserted into the hole
14
formed inside the socket section
15
which having a function to hold the tag, so that a predetermined tag
400
can be attached to the good
200
with reducing the filament section
12
into a loop like configuration.
Note that, in the present invention, the above-mentioned loop-pin
10
as shown in
FIG. 7
can be used, individually, one by one, but in many cases, in order to improve working efficiency, a loop-pin sheet
600
as shown in
FIG. 9
in which a plurality of loop-pins
10
are arranged in parallelism with each other can be used.
Note that as shown in
FIG. 9
, the sheet of loop-pins
600
has a configuration in that which comprises a plurality of unit loop-pins
10
are arranged adjacently to each other with the respective filament sections
12
being arranged in parallelism to each other, and further, a plurality of the insertion head sections
13
which being also adjacently arranged to each other or portions in the vicinity of the insertion head sections
13
and a plurality of socket sections
15
also being adjacently arranged to each other or portions in the vicinity of the socket sections
15
, are connected to each one of a pair of connecting bars
24
and
24
′, respectively, and the inserting head sections
13
or the portions located near by the inserting head sections
13
, and the socket sections
15
or the portions located near by the socket sections
15
are respectively connected to each one of the connecting bars
24
and
24
′, via joint members
11
and
11
′.
In the sheet of loop-pins
600
, each one of the unit loop-pins
10
is made of a synthetic resin material such as ordinal nylon resin, polypropylene resin, polyester resin or the like and also the insertion head section
13
, the socket section
15
and the filament section
12
thereof being integrally molded into one body.
Further the sheet of loop-pins
600
is mounted on a loop-pin attaching device
20
as shown in
FIG. 10
as one embodiment of a conventional loop-pin attaching device and each one of the unit loop-pins
10
can be shot out one by one, respectively, at every time when an operation lever
22
is operated, so that the respective unit loop-pins
10
can be attached to a good with a necessary label.
FIG. 10
shows a condition in that the loop-pin sheet
600
as used in this embodiment is mounted on a loop-pin attaching device
20
.
On the other hand,
FIG. 11
shows a top plan view of a loop-pin attaching device
20
as used in this embodiment, and it shows that a pair of vertical grooves
40
and
41
into which the above-mentioned connecting bars
24
and
24
′ of the loop-pin sheet
600
, being inserted, respectively, are provided on both side of the loop-pin attaching device
20
.
For example, the connecting bar
24
′ to which the socket sections
15
of the loop-pin sheet
600
are connected, is inserted into the vertical groove
40
while the connecting bar
24
to which the insertion head section
13
of the loop-pin sheet
600
are connected, is inserted into the vertical groove
41
.
On the other hand, the loop-pin attaching device
20
as used in this embodiment is provided with a shooting pin
42
which is driven by the operational lever
22
on a side portion of the vertical groove
41
so that the inserting head section
13
is cut off from the joint member
11
′ connected to the connecting bar
24
and thereafter, it can be pushed out forwardly along an inside pass of the cylindrical hollow needle
21
, one by one.
On the other hand, the socket section
15
thereof is pushed out forwardly along an inside pass of the curved cylindrical guide tube portion
43
with a suitable pushing means
25
, for example, a pushing means with a gear-rack mechanisms, and thereafter it will meet and be coupled with the inserting head section
13
at a tip end portion
44
of the guide tube portion
43
.
However, in the embodiment of the loop-pin attaching device
20
as mentioned above, since the curved cylindrical guide tube portion
43
is fixedly attached to a overall front surface of a main body portion of the loop-pin attaching device
20
, there frequently have been occurred some problems in which the socket section
15
of the loop-pin
10
is jammed inside the curved cylindrical guide tube portion
43
or the curved cylindrical guide tube portion
43
has been broken or damaged by a shock when it is applied to the curved cylindrical guide tube portion
43
, due to the loop-pin attaching device
20
being fallen down on a floor or due to the loop-pin attaching device
20
being in collision with another component, another device, a desk, a table or the like so as to generate some significant shock.
In this case, in the past, it was necessary to completely replace an over-all main body portion of the current with a new loop-pin attaching device
20
so as to increase the production cost.
Further, in the loop-pin attaching device
20
, as shown in
FIG. 12
, when an operator wishes to attach a tag or the like to a desired good, first, a hole
410
of the tag
400
is engaged with the hollow needle
21
of the loop-pin attaching device
20
, and thereafter, by operating the operational lever
22
, each one of the filament section
12
of the respective loop-pins
10
is attached to a good
200
by reducing the filament section into a looped configuration.
However, this embodiment has another problem as mentioned hereunder.
Note that, when a projection length of the hollow needle
21
which is calculated from a surface
26
of the loop-pin attaching device
20
to the most tip end portion of the hollow needle
21
, is set at the longer value, a distance formed between the tip end portion of the hollow needle
21
and the tip end portion
44
of the curved cylindrical guide tube portion
43
