Abstract

PROBLEM TO BE SOLVED: To easily and accurately regulate a projecting amount of a utensil body by a method wherein a main sliding body which can move in the longitudinal direction based on a holder, and a subsidiary sliding body which can move in the longitudinal direction based on the main sliding body, and can connect the utensil body, are provided, and the main and subsidiary sliding bodies are made connectable with a connecting mechanism. SOLUTION: When an instant returning motion is performed, an engaging body 49 of a connecting mechanism 6 is turned forward and set at an unused location, and the connection between a main sliding body 2 and a subsidiary sliding body 4 is released. In this case, the engaging body 49 is engaged with a holding piece 51 on the front side and is held under the same state. Therefore, when the subsidiary sliding body 4 is moved forward while resisting an elastic body which is built in the subsidiary sliding body 4, a blade body 90 moves in the same direction, and is projected from a holder 80. Then, when the subsidiary sliding body 4 is released, the subsidiary sliding body 4 instantly moves backward by the elastic body, and the blade body 90 is housed in the holder 80. When the instant returning motion is not performed, the engaging body 49 of the connecting mechanism 6 is turned to the rear side, and set at a using location, and the main sliding body 3 and the subsidiary sliding body 4 are placed under a connected state.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a quick back slider (instantaneous return type slider) used for a manual tool such as a cutter knife, a file or an eraser having the same structure.

[0002]

2. Description of the Related Art Conventionally, as this kind of quick back slider, for example, one described in Japanese Patent Application Laid-Open No. 6-315577 is known. Basically, this is a main slide that can move in the front-rear direction with respect to the holder, an indwelling mechanism that holds the main slide in the holder, and a road that can move in the front-rear direction with respect to the main slide. A sub-sliding body capable of connecting concrete;
An elastic body that always moves the sub-sliding body backward with respect to the main sliding body,
It is composed of Thus, in such a device, after the main sliding member is held at a predetermined position with respect to the holder by the holding mechanism, and the sub-sliding member is moved forward against the elastic member, the way of the holder is changed. It can be pulled out from the front side by a predetermined amount to perform pulling work such as cutting, and when the thumb is released, the sub-sliding body is immediately moved backward by the elastic body so that the road concrete is stored in the holder. It is possible to accurately adjust the amount of protrusion of the road.

[0003]

However, in the case of such a cutter, as in the case of a normal cutter knife, the main slide is operated to protrude a predetermined distance from the front side of the holder, and then a pull such as cutting is performed. When the work was performed, the sub-sliding body was connected to the main sliding body by the indwelling mechanism by the elastic body. This kind of work couldn't be done properly. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been made in order to solve the problem. The object of the present invention is to accurately adjust a projecting amount of a road, and to perform a normal cutting. Another object of the present invention is to provide a quick back slider that can appropriately perform pulling operations such as pulling.

[0004]

A quick-back slider according to the present invention basically comprises a main sliding member movable in the front-rear direction with respect to a holder, and a retaining mechanism for retaining the main sliding member with respect to the holder. A sub-sliding body movable in the front-rear direction with respect to the main sliding body and capable of connecting a road, an elastic body that always moves the sub-sliding body backward with respect to the main sliding body, a main sliding body and a sub-sliding body. And a connecting mechanism for connecting the two.

When the instantaneous return operation is performed, the connection between the main sliding member and the sub-sliding member is released by a connecting mechanism. With this arrangement, when the sub-sliding body is moved forward against the elastic body, the road follows. When the sub-sliding member is opened, the sub-sliding member is immediately moved backward by the elastic member, and the road is followed.
This can be achieved by placing the road concrete protruding from the holder when the sub-sliding body moves forward, and storing the road concrete in the holder when the sub-sliding body is opened. Accordingly, by moving the main sliding body back and forth with respect to the holder and holding the main sliding body by the holding mechanism, it is possible to accurately adjust the amount of projection of the road relative to the holder. When the instantaneous return operation is not performed, the main sliding member and the sub-sliding member are connected by a connecting mechanism. With this arrangement, the sub-sliding member cannot be moved back and forth with respect to the main sliding member held by the holding mechanism. Therefore, even if the main slide is operated to protrude the road concrete from the front side of the holder by a predetermined amount and then a pulling operation such as cutting is performed, the sub-slide and the road concrete are inadvertently moved with respect to the main slide. It does not move and can perform this kind of work properly.

The connecting mechanism is provided on the sub-sliding body and is rotatable from a used position to a use position. The connecting mechanism is provided on the main sliding body and engages with the main body at the use position of the hanging body. It is preferable to include a latching piece for preventing the sub-sliding body from moving forward with respect to the sliding body, and a holding piece provided on the sub-sliding body to hold the latching body at the used position and the used position. If you do this,
The structure is relatively simple, the cost is not much, and it can be easily applied to the conventional one.

The hooking body 49 has a four-frame shape, and one of the short pieces is formed in a columnar shape, and is removably fitted in a fitting groove 52 formed on the front side of the crown 27 of the sub-sliding body 4. 2 is rotatable around the vertical axis from a used position tilted forward as indicated by a solid line to a used position tilted rearward as indicated by a chain line in FIGS. The locking piece 50 is provided on the raised portion 8 of the main sliding body 2.
And the other short piece of the latching body 49 is hooked when in the use position. A pair of upper and lower holding pieces 51 are formed on the front and rear sides of the crown 27 of the sub-sliding body 4 so that the middle of the upper and lower long pieces of the hooking body 49 is hooked.

Such a slider 1 is assembled as follows. The leaf spring body 10 is put on the elastic hooking body 9 of the retaining mechanism 3 formed on the substrate 7 of the main sliding body 2 so as to overlap. After the operation body 11 is disposed on the front side of the substrate 7 of the main sliding body 2, the release projection 24 is inserted into the guide hole 14 and is strongly pressed, so that the retaining portions 25 and 16 are permanently engaged. Then, the release protrusion 24 is located between the free end of the forwardly inclined elastic piece 18 and the backwardly inclined elastic piece 20 of the leaf spring body 10, and the main slide 2
The operation body 11 is combined so as to be able to move back and forth. Next, after the dovetails 40 formed on the main sliding body 2 are inserted into the dovetail grooves 41 through the open grooves 42 formed on the sub-sliding body 4,
The shaft portion of the spring holder 47 into which the compression coil spring 48 is inserted is inserted into the through hole 45 formed in the main slide 2 to compress the compression coil spring 47 and form the cone of the spring holder 47 in the sub slide 4. The elastic member 5 is made to fit into the main sliding member 2 and the sub-sliding member 4
Interposed between Then, the hook 36 of the crown 27 of the sub-sliding body 4 is hooked into the hook hole 33 of the base 26, and
The base 26 and the crown 27 are united by closing the hook portion 37 with the hanging step portion 34 to close the accommodation cavity 32. Then, when one short piece of the hook body 49 of the connecting mechanism 6 is fitted into the fitting groove 52, the slider 1 is assembled.

The assembled slider 1 comprises a main sliding body 2
Grooves are respectively formed in the upper and lower portions between the main sliding body 2 and the operating body 11, and the upper and lower grooves between the base body 26 and the crown body 27 of the sub-sliding body 4. Inside, the leaf spring body 10
The front tilting piece 18 and the rearward tilting piece 20 are facing. Thus,
After the slider 1 is connected to the connecting projection 30 of the sub-sliding member 4 by inserting the connecting hole 91 of the blade body 90 into the connecting protrusion 30, the upper and lower front walls of the sheath 81 of the holder 80 are fitted into the upper and lower concave grooves. 8
0 is inserted from the rear side so as to be able to move back and forth, and a clip 83 is fitted to the rear part of the grip 82 of the holder 80 to make a cutter knife 70 as shown in FIG.

Next, the operation will be described based on such a configuration. When performing the instantaneous return operation, as shown by the solid lines in FIGS. 1, 3, 4, 6, and 7, the latching body 49 of the coupling mechanism 6 is tilted to the front side to be in the non-use position. The connection between the main slide 2 and the sub-slide 4 is released. At this time, the hooking body 49 is hooked on the front holding piece 51 and held in the same state. With this arrangement, as shown in FIG. 7, when the sub-sliding body 4 is moved forward against the elastic body 5, the blade body 90 follows. When the sub-sliding member 4 is opened, the sub-sliding member 4 is instantaneously moved backward by the elastic member 5 and the blade body 90 follows. As shown by the chain line in FIG. 1, when the sub-sliding body 4 moves forward, the blade body 90 projects from the holder 80, and as shown by the solid line in FIG.
This can be achieved by placing the blade body 90 in the holder 80 when the sub slide 4 is opened. Accordingly, the amount of protrusion of the blade body 90 with respect to the holder 80 can be accurately adjusted by moving the main sliding body 2 back and forth with respect to the holder 80 and holding the main slide body 2 with the holding mechanism 3.

When the instantaneous return operation is not performed, FIG.
As shown by chain lines in FIGS.
The main sliding member 2 and the sub-sliding member 4 are connected to each other by moving the sliding member 9 rearward to the use position and engaging with the engaging piece 50.
At this time, the hook body 49 is hooked on the rear holding piece 51 and held in the same state. If placed in this way, the detention mechanism 3
Cannot move the sub-sliding body 4 back and forth with respect to the main sliding body 2 which is placed. Therefore, even if the main sliding body 2 is operated to cause the blade body 90 to protrude from the front side of the holder 80 by a predetermined amount and then a pulling operation such as cutting is performed, the sub-sliding body 4 and the blade body The 90 is not inadvertently moved forward, and this kind of work can be performed properly.

FIG. 2 shows a case where the main slide 2 is stopped with respect to the holder 80 and is in a so-called auto-lock state. At this time, the operating body 11 is at the neutral position, and the free ends of the forwardly inclined elastic piece 12 and the backwardly inclined elastic piece 13 of the elastic hooking body 9 are respectively inclined with the forwardly inclined elastic piece 18 of the leaf spring body 10. The projecting piece 20 is engaged with two spaced-apart retaining recesses 86 of the multiple retaining recesses 86 of the holder 80 via the respective free ends. The release projection 24 is provided on the elastic hooking body 9 and the forwardly inclined elastic piece 1 of the leaf spring body 10.
The elastic members are located between the free ends of the rearwardly inclined elastic pieces 13 and 20 to allow the engaging concave portions 86 to engage with them. In such a state, when the main sliding body 2 moves forward, the forwardly inclined elastic pieces 12,
18 and the engaging recess 86 are engaged with each other,
2, 18 function as so-called support rods, which are prevented. Conversely, when the main sliding body 2 is going to move backward, the rearwardly elastic pieces 13 and 20 of the elastic hooking body 9 and the leaf spring body 10 are engaged with the engaging concave portion 86, so that the backwardly inclined elastic pieces 13 and 20 functions as a so-called support rod, which is prevented. Therefore, even when an external force acts, the main sliding body 2 does not move in any of the front and rear directions, and is so-called auto-locked to the holder 80.

When the main slide 2 is advanced with respect to the holder 80, the operating body 11 at the neutral position is moved forward. Then, the elastic projections 24, 18 of the elastic hooking body 9 and the leaf spring body 10 and the hooking recess 8 of the holder 80 are formed by the release projection 24.
6 is released, and the main sliding body 2 and the operating body 11 move forward together while maintaining the same state. At this time, the rearwardly elastic pieces 13 and 20 of the elastic latching body 9 and the leaf spring body 10 repeatedly engage and disengage with the retaining concave portion 86 of the holder 80, so-called step slide.

When the main slide 2 is moved backward with respect to the holder 80, the operating body 11 at the neutral position is moved backward. Then, the operating body 11 is in the rearward movement position, and the release protrusion 24
Of the elastic hooking body 9 and the leaf spring body 10,
Only the engagement between 20 and the engaging recess 86 of the holder 80 is released, and the main sliding body 2 and the operating body 11 move backward together while maintaining the same state. At this time, the elastic hook 9 and the leaf spring 10
The forward tilting pieces 12 and 18 repeatedly engage with and disengage from the retaining concave portion 86 of the holder 80, so-called step slide.

As compared with the conventional one, only the connecting mechanism 6 for connecting the main sliding body 2 and the sub-sliding body 4 is provided, so that the present invention can be easily implemented without increasing the cost. Since the elastic body 5 uses the compression coil spring 48, it can exhibit more stable elastic force than the tension spring. Elastic body 5
Sets the compression coil spring 48 in the spring holder 47
It does not buckle because it was inserted through. Since the temporary coupling mechanism 39 is provided between the main sliding body 2 and the sub-sliding body 4,
The same state can be maintained only by applying a engaging force smaller than the elasticity of the elastic body 5. Since the leaf spring body 10 which is detachably mounted on the elastic hook body 9 is provided, when the holder 80 is made of press-formed metal, the elastic hook body 9 is made of synthetic resin and the leaf spring body 10 Can be made of metal. In this way, even if the surface roughness of the retaining recess 86 of the holder 80 is roughened by press molding, the elastic retaining body 9 made of synthetic resin is engaged via the leaf spring body 10 made of metal. Therefore, the elastic locking body 9 made of synthetic resin is not worn. When the elastic hook 9 is made of synthetic resin and the leaf spring 10 is made of metal, both the tension force and the elastic restoring force can be increased. Since the angle formed by the forward inclined piece 18 and the backward inclined piece 20 of the leaf spring body 10 is smaller than the angle made by the forward inclined piece 12 and the backward inclined piece 13 of the elastic hooking body 9, The leaf spring body 10 can be easily put on the elastic hooking body 9.

The indwelling mechanism 3 is a so-called auto-lock type in the above example, but is not limited thereto.
A step-sliding type described in 1-30609 or a screw type described in JP-A-6-315577 may be used. In the above example, the sub-slider 4 is arranged on the front side of the main slide 2, but is not limited to this, and may be, for example, on the rear side. The elastic body 5 uses a compression coil spring in the above example,
The invention is not limited to this, and for example, a tension spring may be used.
In the previous example, the connecting mechanism 6 provided the hook 50 on the main sliding body 2 and provided the hook 49 and the holding piece 51 on the sub-sliding body 4. However, the present invention is not limited to this. You may do it. The manual tool 70 is a cutter knife in the above example, but is not limited thereto, and may be a hand tool such as a file having the same structure, a stationery such as an eraser, or the like. The holder 80 is
In the above example, the grip 82 and the clip 83 are provided, but the present invention is not limited to this, and they may be omitted, for example. In the above example, the blade body 90 has a standard blade folding pitch, but is not limited to this, and may be, for example, a half of the standard.
