Description

[Detailed description of the invention] The present invention relates to paper scissors, and in particular, it simplifies the attachment of the crankshaft and presser frame, improves the appearance, and increases the pressing force of the presser frame. The embodiment will be described in detail with reference to the plan view below. Reference numeral 1 is a plywood board, one edge of which is bent at right angles to form a wall board 2, and this base board 1
The nail plates 3 are cut and raised in three places so that they are parallel to the wall plate 2.

Among these nail plates 3, between the central nail plate 3 and the wall plate 2,
It passes through the shaft 4 and has a large diameter head at the inner end of the shaft 4,
Further, a stop portion 5 is formed by a pusher on the outer end, and these prevent the shaft 4 from coming off.

The base end of the bundle 6 is rotatably attached to the shaft 4, and a coil spring 7 is inserted, one end 7 of the coil spring 7 is extended and stored and fixed in a groove in the bundle 6. The end is extended to form a middle arm 8, and the tip of this middle arm 8 is further bent at a right angle to form a front arm 9.

The lower arms 11 of the crankshaft 10, which are made of metal rods, are passed through the two claw plates 3 and 3 between the claw plates 3 and the wall plate 2, respectively, and the outer ends of the lower arms 11 are crushed to form the stop portions 12. a middle arm 13 which is bent at a right angle from the lower arm 11 and extends upward;
A front arm 14 is formed at the tip of the lower arm 11 and is bent at a right angle in the opposite direction to the lower arm 11.

The presser frame 15 supported by the forearm 14 is made of a long and thin metal plate formed so that its center bulges upward in the longitudinal direction. The fore arms 14 are attached to the presser frame 15 so as to pass through it in the width direction, and the fore arms 9 of the spring 7 are also attached to the presser frame 15.
The rotation of the bundle 6 causes the middle arm 8,
When the presser frame 13 rotates from a substantially perpendicular state to a substantially horizontal state with respect to the base plate 1, the presser frame 15 moves up and down while maintaining a state parallel to the base plate 1.

The front arm 14 of the crankshaft 10 is connected to the side wall 1 of the presser frame 15.
5 is crushed at two locations that contact the inner surface of the presser frame 15, thereby forming stop portions 16 that prevent the presser frame 15 from being removed (FIG. 3).

The present invention provides the crankshaft 10 in the above-described configuration.
The lower arm 11 and the front arm 14 of the bundle 6 are inclined parallel to each other downward at a slight angle α with respect to the base plate 1 as shown in FIG.
is similarly tilted.

Reference numeral 17 denotes an engagement hole that engages with a locking piece 18 provided at the free end of the bundle shaft 6 to maintain the pressing state of the presser frame 15 against the base plate 1.

Then, the bundle 6 is rotated against the spring 7 to lower the presser frame 15 toward the base plate 1, and the locking piece 18
By locking in the engagement hole 17, the presser frame 15 of the base plate 1 is
Holds paper sheets, etc., interposed between the

In the present invention, the lower arm 11 and the front arm 14 of the crankshaft 10 are formed so as to be inclined parallel to the downward direction at a slight angle α with respect to the surface of the base plate 1. 10 is laid down in a substantially horizontal state by operating the bundle 6, the lower surface of the outer edge of the presser frame 15 comes into contact with the base plate 1 first, and then the lower surface of its inner edge comes into contact with the base plate 1, as shown in FIG.

Therefore, the object to be held between the base plate 1 and the holding frame 15 is particularly strongly pressed by the outer edge of the holding frame 15.

That is, compared to the conventional structure in which the lower arm and front arm of the crankshaft are parallel to the plywood surface, the pressing force exerted by the pressing frame is increased.

Furthermore, in the present invention, the fore arm provided at the tip of the crankshaft penetrates the side wall of the presser frame and has stop portions formed by pressing at two locations where it contacts the inner surface of the side wall. The work of preventing the presser frame from coming off from the arm can be performed very easily, and since the stop portion is not exposed to the outside, it has the advantage of being very aesthetically pleasing.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention, in which Fig. 1 is a general perspective view with the presser frame raised, Fig. 2 is a vertical sectional view thereof,
FIG. 3 is a partial perspective view of the crankshaft, and FIG. 4 is a vertical sectional view of the presser frame in a lowered state. In the figure, 1 is a base plate, 2 is a wall plate, 3 is a nail plate, 6 is a bundle, and 7
1 is a coil spring, 8 and 13 are middle arms, 10 is a crankshaft, 9 and 14 are front arms, 15 is a presser frame, 15' is a side wall, 1
6 is a stop portion.

Claims (1)

[Scope of utility model registration request] A presser frame supported by plywood and a plurality of crankshafts attached to the plywood so as to move up and down parallel to the plywood;
In paper scissors, which is equipped with a bundle that presses down the presser frame against a spring, and which holds documents between the plywood and the presser frame, the lower arm and the front arm of the crankshaft are slightly aligned with the horizontal plane of the base plate. The paper scissors are tilted parallel to the downward direction at a certain angle, the fore arm is passed through the side wall of the presser frame, and the inner surface of the side wall is pressed to form stop portions at two places that contact the paper scissors.
