Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a spring material mounting structure for scissors that acts on the leg handle of scissors incorporated in pocket knives etc. to open the blade of the scissors. It is.

(Prior Art) Conventionally, for example, scissors have a pair of intersecting blades that can be opened and closed from each other at approximately the center position among the various functional parts that are stored together with the knife in the handle of a pocket knife, which consists of a pair of side plates. Along with riveting,
A fixed leg handle of one of the blades is rotatably pivoted to the handle. In the scissors, a cut is formed at the base end of the fixed leg handle, and the base of the spring plate is inserted so that the tip of the spring plate presses the movable leg handle of the other blade. This makes it possible to repeatedly cut objects by closing the blade corresponding to the open movable leg handle against the elasticity of the spring plate, and then opening the blade again due to the elasticity of the spring plate. Adopts a spring plate mounting structure.

(Problem to be solved by the invention) However, in the spring plate mounting structure of the scissors described above, if the action of pressing the movable leg handle is repeated using the scissors for a long period of time, the spring plate in the pressed state will come out of the pressed state. Its tip swings from side to side in an attempt to escape.
There was a problem that it was sometimes impossible to open the blade by pressing the movable leg handle correctly. The tip of the spring plate swings left and right because the base of the spring plate is inserted into a cut in the base of the metal fixed leg handle. This occurs because even if the base of the spring plate and the cut are inserted in a tight state, the movement of the tip of the spring plate is transmitted little by little and the close contact loosens.

In addition, in the spring plate mounting structure of the scissors, it is necessary to manually form a cut at the base end of the fixed leg handle using a metal saw, which is not only difficult but also requires cutting the saw blade. There were problems in that uniform cuts could not be formed due to wear and other causes, and it was difficult to maintain a state in which the base of the spring plate and the cuts were in close contact with each other.

Therefore, the purpose of this invention is to be able to easily assemble it by anyone, to easily manufacture products with uniform quality, and to ensure that the movable leg handle can be reliably manufactured even after long-term use. To provide a spring material mounting structure for scissors incorporated in a completely new pocket knife or the like, which can open the blade by pressing the scissors.

(Means for Solving the Problems) In order to solve the above-mentioned problems, in the invention according to claim 1, the fixed leg handle of one blade rotatably pivoted between a pair of side plates is provided. , in a spring material mounting structure of scissors incorporated in a pocket knife, etc., in which a spring material is attached that acts on the movable leg handle of the other blade to bias the blade in a direction to open the blade, the base of the fixed leg handle An engagement hole is transparently provided at the end, a recessed part that engages with the base of the spring material and holds the base between the back surface of the fixed leg handle, and an engagement that engages with the engagement hole. The present invention is characterized in that a substrate having a protrusion is disposed on the back surface of the fixed leg handle.

Further, in the invention as claimed in claim 2, an engagement hole is provided in the base end of the fixed leg handle, and the engagement hole is engaged with the base of the spring material to allow the base to be connected between the back surface of the fixed leg handle and the base end of the fixed leg handle. A substrate is attached to the fixed leg handle, and includes a concave portion to be held between the fixed leg handle and the fixing leg handle. It is characterized by being placed on the back side of the .

(Function) With the above-described configuration, by simply engaging the engagement protrusion into the engagement hole of the fixed leg handle while the base of the spring plate is engaged with the recessed part, the board can connect the base of the spring plate to the fixed leg handle. It can be easily and reliably attached to the back surface of the fixed leg handle by sandwiching it between the fixed leg handle and the fixed leg handle. Furthermore, if you insert the caulking pin into the pin hole of the fixed leg handle and the pin hole of the board,
The board is firmly attached to the back surface of the base end of the fixed leg handle.

The base of the spring plate engages with the recess and is securely clamped between the recess and the back surface of the fixed leg handle, so that the tip of the spring plate can move left and right. I can't shake it. Therefore, the movable leg handle is reliably pressed by the spring plate over a long period of time, and the blade is reliably urged in the opening direction.

(Example) An example embodying the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the handle of the pocket knife is composed of a pair of side plates 50 and 51.
Scissors S are incorporated between the same side plates 50 and 51 together with functional parts such as a knife.

The scissors S has a pair of upper and lower blades 10 and 2 that intersect with each other.
0 are riveted to each other at approximately the central position so that they can be opened and closed.

Fixed leg portion 11 base end portion 11 of the one blade 10
A pin hole 12 is transparently provided in a, and a caulking pin 60) is inserted into the pin hole 12, so that the scissors S is rotatably attached between the side plates 50 and 51. Further, a substantially elliptical engagement hole 13 is transparently provided in the base end 11a of the fixed leg handle 11, which is located slightly closer to the tip of the pin hole 12.

An engagement protrusion 31 protruding from a substantially rectangular plate-shaped substrate 30 made of synthetic resin is engaged with the engagement hole 13 . The substrate 30 is disposed in close contact with the back surface of the base end portion 11a of the fixed leg handle 11.

A pin hole 32 is transparently provided in the substrate 30, and the caulking pin 60 is inserted therethrough. The substrate 30 is configured to rotate integrally with the base end portion 11a between the side plates 50 and 51.

The substrate 30 is provided with a concave portion 33 on the upper surface (the surface on the base end 11a side) from the center to the tip, which engages with the base of the spring plate 40 as a spring material. The base of the spring plate 40 is held between the concave portion 33 and the back surface of the fixed leg handle 11. The spring plate 40 is wound so that its base end is circumferential, and is attached so as not to slip out of the concave portion 33.

The tip of the spring plate 40 is connected to the other blade 2.
The movable leg handle 21 of the blade 20 is bent toward the 0 side.
The movable leg handle 21 is pressed by its own elasticity and biased in the direction of opening the blade 20.

The effects of the spring material mounting structure configured as described above will be explained. First, when attaching the spring plate 40 to the scissors S, the base of the spring plate 40 is engaged with the concave portion 33 of the base plate 30, and in this state, the engagement protrusion 31 of the base plate 30 is engaged with the fixed leg handle 11. It is engaged with the hole 13. Then, the both side plates 50 and 51 are superimposed on the upper surface of the base end 11a of the fixed leg handle 11 and the back surface of the board 30, and the caulking pins 60 are inserted into both the pin holes 12 and 32.
Anyone can easily and reliably complete the work of attaching the spring plate 40 to the fixed leg handle 11 of the scissors S by inserting it through and caulking the side plates 50, 51.

Further, the engagement protrusion 31 of the board 30 is connected to the fixed leg handle 11.
Furthermore, since the caulking pin 60 is inserted into the pin hole 12 of the fixed leg handle 11 and the pin hole 32 of the base plate 30, the base plate 30 is inserted into the base of the fixed leg handle 11. It can be firmly attached to the back surface of the end portion 11a.

Next, in order to open and close both blades 10 and 20 of the scissors S to cut an object, the scissors S is rotated around the caulking pin 60 from between the side plates 50 and 51, and the scissors S is pulled out. Then, as shown in FIG. 3, when the movable leg handle 21 of the blade 20 is pressed against the elasticity of the spring plate 40, the blades 10, 20 are closed and cut the object.

When the pressure on the movable leg handle 21 is released, the movable leg handle 21 is pressed by the spring plate 40, so that the blade 20 is opened again. By repeating these operations, objects can be cut repeatedly.

In repeating the operation, the spring plate 40
The base of the spring plate 40 engages with the concave part 33 and is securely clamped between the concave part 33 and the back surface of the fixed leg handle 11. The movable leg handle 21 can be reliably pressed and biased in the direction of opening the blade 20 over a long period of time without swinging.

Note that the present invention is not limited to the above-mentioned embodiment, and may be implemented by incorporating only the scissors S between the side plates 50 and 51, or in this embodiment, the side plates 50 and
Although the outer shape of the substrate 30 was designed to be the same as the base end 11a of the fixed leg handle 11 so as not to protrude from the base 51,
Ignoring this, if the design allows it to protrude from the side plates 50, 51, it may be implemented by changing its size as appropriate, without departing from the spirit of the present invention. .

Further, the substrate 30 may be made of synthetic resin or metal, which may be appropriately selected to take advantage of their advantages.

In addition, since the base end of the spring plate 40 is wound so as not to slip out forward from the concave part 33, the base end may be made into an L-shape to prevent it from coming out from the concave part 33, or the shape of the spring plate 40 may be changed. The shape and material may be selected as appropriate, such as being made of a round bar-shaped spring material.

(Effects of the invention) As detailed above, in the spring material mounting structure of the scissors incorporated in the pocket knife etc. according to the invention, when the base of the spring plate is engaged with the recessed part,
Simply engage the engagement protrusion into the engagement hole of the fixed leg handle.
By holding the base of the spring plate between the fixed leg handle and the fixed leg handle, the board can be easily and reliably attached to the back surface of the fixed leg handle. Furthermore, the pin hole of the fixed leg handle,
By inserting a caulking pin into the pin hole of the board, the board can be firmly attached to the back surface of the base end of the fixed leg handle.

Furthermore, the spring plate is attached so that its base engages with the concave part and is securely sandwiched between the concave part and the back surface of the fixed leg handle, so that the tip of the spring plate can move from side to side. It does not swing, and has the excellent effect of being able to reliably press the movable leg handle over a long period of time with the spring plate and reliably bias the blade in the direction of opening.
