Description

  The present invention relates to a punch, and more particularly, to a punch that maintains stability when used.

  A punching apparatus which is a conventional punch as the background of the present invention is disclosed in, for example, Japanese Patent Application Laid-Open No. 2010/17775 (see Patent Document 1).

Such a punch is required to have a compact configuration as a whole for reasons of material cost and space securing when not in use.
The width of the punch in the direction in which the punch blades protrude at equal intervals (hereinafter referred to as “the vertical width of the punch”) is because the punch blades for punching the material to be drilled protrude at equal intervals. That length is necessary and cannot be shortened.
On the other hand, with respect to the punch width in the direction perpendicular to the direction in which the punch blades are projected at equal intervals (hereinafter referred to as “the width of the punch”), when the punch is short, the user rotates the lever. In addition, there arises a problem that the main body rotates with respect to the surface on which the punch is placed, with one end edge of the base body as a fulcrum. Although it is conceivable to suppress the rotation of the main body itself by shortening the length of the lever, the lever also needs to have a certain length in order to reduce the load on the user's lever rotation.
Due to such problems, the punch cannot be made compact.

  Therefore, a main object of the present invention is to provide a punch that can be compact when not in use while maintaining the stability of the punch when in use.

  The present invention is not limited to the above embodiment, and various modifications can be made based on the idea of the present invention.

The support 200 may have a configuration different from the above-described configuration so that the punch 10 can be displaced with respect to the base body 12 in order to take the second form.
As shown in FIGS. 13 to 15, the base body 12 may be slidable inward to be housed inside the base body 12.

The support body 200 is a rod-shaped body having a longitudinal direction, and is formed so as to advance and retract along the first side wall plate portion 34.
The support body 200 can be retracted from the near side of the base body 12 toward the far side along the linear sliding guide body 220 formed along the first side wall plate portion 34. It is stored in.

  An axis that is perpendicular to the bottom surface of the base body 12 and is an area in which the support body 200 and the base body 12 overlap when the punch 10 is in the first configuration when the punch 10 is viewed in plan The base body 12 may be housed by rotating about the axis at the center.

As shown in FIGS. 16 and 17, the support 200 is a rod-like body having a longitudinal direction, and is supported in the vicinity of one end (the other side) in the longitudinal direction.
The support shaft portion 230 that pivotally supports the support body 200 is attached to the base body 12 in the vicinity of the rotation shaft 52 of the operation lever 50.
The support body 200 extends toward the front side from the support shaft 230, and the front side is rotated from the first side wall plate 34 side toward the inside of the base body 12 to be stored inside the base body 12. Is done.

The operation lever 50 may include a longitudinal direction extending in the short direction of the material P to be punched placed on the base body 12 and extendable in the longitudinal direction of the operation lever 50.
As shown in FIGS. 18 and 19, the operation lever 50 includes an arm member 356 on the rotating shaft side and a handle member 358 on the free end side, and a slide rail body 356 a and a handle member 358 of the arm member 356. The sliding rail body 358a is slidably connected so as to extend and contract.

The adjustment alignment body 110 and the stopper 150 may be changed as shown in FIGS.
The adjustment alignment body 110 is elastically attached by an elastic member 180 wound around the lower end of the shaft portion 112.
The adjustment alignment body 110 is prevented from coming off from the stopper member 160 by the elastic member 180 and rotates around the shaft portion 112 while being pressed against the upper surface of the stopper member 160.
The stopper member 160 has a protrusion 152 formed by a hemispherical protrusion protruding upward from the upper side of the stopper main body 162.

  The stopper main body 162 is located inside the stopper body fitting and fixing portion 170 formed in the mounting plate portion 30 of the base body 12 and inside the second side wall plate portion 36 of the base body 12. Is engaged.

  Thus, when the adjustment alignment body 110 is rotated while being pulled up slightly, the first intermittent stop recess 130 formed inside the first alignment surface 120 or the inside of the second alignment surface 122 is rotated. Each time the second intermittent stop recess 132 formed in the second intermittent stop recess 132 or the third intermittent stop recess 134 formed inside the third alignment surface 124 and the elastic support portion 154 of the stopper 150 are rotated. Then stop.

A method of using the punch 10 according to the present invention will be described.
A sheet as the material P to be perforated is prepared, and the adjustment alignment body 110 is rotated in accordance with the size (A4, A5, B5 size) of the sheet, and the first alignment surface 120 and the second alignment surface 120 are rotated. The alignment surface 122 and the third alignment surface 124 are set along alignment lines (first alignment line L3a, second alignment line L3b, and third alignment line L3c).
Then, the perforated material P is inserted into the slit 60, the long end edge on the binding margin side is along the front side surface of the alignment convex portion 100, and the short end edge is the first position of the adjustment alignment body 110. The first alignment surface 120, the second alignment surface 122, or the third alignment surface 124.
Then, if the operation lever 50 is rotated, the binding hole H can be punched in the punched material P as shown in FIG.
