Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stapler with a punch that allows paper binding and punching to be performed separately and reliably with an extremely simple configuration, and is disclosed in Patent No. 809831 previously filed by the present applicant. This invention is a further improvement on the invention of No.

Conventionally, as a stapler equipped with a punch device, (1
) A punch blade is installed inside the base or frame, and the head of the punch blade is pressed by the frame or handle to perform hole-drilling work, (2) One end of the handle and base is extended, and this (3) with a punch device in the extension;
There are some that have a punch hole in the middle part of the base and a punch blade fixed to the middle part of the frame to make the hole. 1-゛4-f-, ding+刹11-゛; t/'u, ITILn
), the base and frame are pivoted at the center of the rear of the frame, similar to conventional general staplers, so the gap between the punch hole and the punch blade becomes larger, making it easier to punch holes securely. There were drawbacks such as the inability to do so.

For this reason, in the above-mentioned patent No. 809831, a punch blade is fixed to the lower surface of the intermediate portion of the frame, and a Nomanche hole through which the punch blade enters and exits is bored in the intermediate portion of the base, so that when the handle and frame are pushed down. , so that the punch blade can vertically move in and out of the punch hole, the pivot position at the rear of the frame and base is set so that the branch line of the rear extension surface of the lower surface of the frame and the rear extension surface of the upper surface of the punch hole are connected to the frame. The frame and base are pivotally connected to each other as a pivot axis to the base, and as a result, ordinary paper can be punched normally.

However, when using the punching device described above, when punching thin paper or special paper, punch waste may be partially cut off or left behind.
There were drawbacks such as an unsightly cut.

This is because the punch blade is directly fixed to the frame, so when the punch blade moves in and out of the punch hole during drilling, it moves in a circle around the pivot shaft at the rear of the base and frame. Since the punch goes in and out, it is necessary to provide a slight gap i between the punch hole and the punch blade, and for this reason, punch waste remains uncut when the paper is thin or the like. Therefore, in order to reliably and easily punch any paper, the punch blade must be able to freely move in and out of the punch hole while maintaining the minimum gap. The present invention obviates the above-mentioned drawbacks and
In order to reliably and easily punch holes in any type of paper, we use a base with a punch hole and a frame with a punch blade attached so that the punch can move freely in and out of the punch hole with the minimum gap. The base and the frame are rotatably connected along a rearward extending parallel line between the tip of the punch blade and the upper limit position of the portion where the punch blade enters and exits the punch hole.

The present invention will be explained below with reference to the drawings.

What is shown in FIGS. 1 to 5 is a first embodiment of the present invention,
In the figure, 1 is a base, 2 is a frame, and 3 is a handle, each of which is rotatably pivoted by pivots 4 and 5 at its rear base end. The base 1 is made of a synthetic material or the like and is formed into a gutter shape with a box-shaped cross section with an open top surface, and has a storage section 6 for punch scraps, staples, etc. from the center to the front end, and has both rear sides facing upward. A side wall 7 is formed protruding from the side wall 7, and an insertion slot 9 for paper 8 is provided at the front portion of the side wall 7, and pivot shafts 4 are provided on both sides of the base end portion facing inward.

A punch stand 10 that fits on the upper surface of the base 1 has both sides bent downward to form a reinforcing edge 11, and a punch hole 12 is punched in the upper surface of the center part, and a bending stand 13 for the binding needle is formed in the front part. , and a spring portion 14 is provided at the rear, and the proximal end portion is rotatably fixed to the protrusion 15. Next, the frame 2 is loaded with staples in the same way as conventional products, and is also equipped with a needle pusher (not shown). In order to perforate the paper 8 inserted from 9,
A punch blade 17 having three or more cutting edges 16 is attached to the tip, a pressing part 18 is formed on the upper surface of the front part, and a pivot part 19 is pivotally connected to the pivot 4 of the base 1 at the rear base end. Further, a pivot portion 20 is provided which is pivotally coupled to the pivot shaft 5 of the handle 3.

Next, a push blade 21 is provided at the front end of the handle 3. At the same time, a handle spring 23 with a spring portion 22 formed on the rear part is attached, and a pivot shaft 5 that fits into the pivot part 20 provided at the rear part of the frame 2 is provided protrudingly on both sides of the rear part. and are pivotably connected.

Note that when punching paper with the punch blade 17 and punch hole 12, in order to reliably punch even thin or special paper, when the punch blade 17 moves in and out of the punch hole 12, both Spaces must be kept to a minimum to allow access.

To do this, a pivot joint 1 is provided at the rear base end of the frame 2.
9 is an important condition. For this reason, in the present invention, as shown in FIG. 4, a cutting edge line 25 of the cutting edge 16, which is perpendicular to the axis 24 of the punching blade 17 mounted on the lower surface of the frame 2, and the punching blade 17 move in and out of the punch hole 12. At the base end along the rear extension line with the upper limit position line 26 of the part,
A pivot door 19 is provided, which reduces the gap between the punch hole 12 and the punch blade 17 to 571/100.
7! Since the punch blade 17 can freely move in and out of the punch hole 12 while keeping the punch hole 12 within
The frame 2 and the handle 3 are pivotally connected to each other by protruding a pivot shaft 5 that fits into the frame 2 and the handle 3. Note that when punching paper with the punch blade 17 and punch hole 12, in order to reliably punch thin or special paper, the punch blade 17 must be
When the material enters and exits the punch hole 12, the gap between the two must be kept to a minimum so that the material can enter and exit the punch hole 12.

To do this, a pivot joint 1 is provided at the rear base end of the frame 2.
9 is an important condition. For this reason, in the present invention, as shown in FIG. 4, a cutting edge line 25 of the cutting edge 16, which is perpendicular to the axis 24 of the punching blade 17 mounted on the lower surface of the frame 2, and the punching blade 17 move in and out of the punch hole 12. At the base end along the rear extension line with the upper limit position line 26 of the part,
A pivot portion 19 is provided, which reduces the gap between the punch hole 12 and the punch blade 17 to 5/100T! R
Since the punch blade 17 freely moves in and out of the punch hole 12 while maintaining the distance within ln, it is possible to reliably and easily punch even thin sheets of paper. In the figure, 27 is the paper release piece, 28 is the finger hook on the punch stand,
29 is a remover.

The present invention is constructed as described above, and when using this as a stapler, by pressing the handle 3,
It can perform paper binding like a conventional stapler, and when used as a punch, as shown in FIG. When pressed downward in the direction of the arrow, the cutting edge 16 of the punch blade 17 fits into the punch hole 12 while penetrating the paper 8, so that the paper 8 can be punched easily and reliably. When the pressure of the pressing part 18 is released after the hole punching operation is completed, the punch blade 17 also rises as the frame 2 rotates upward due to the elasticity of the spring part 14, but the paper 8 in the insertion slot 9 is Since the paper 8 remains in the insertion slot 9 blocked by the detachment piece 27, the paper 8 can be easily removed.

In addition, in order to take out punch scraps, replenishment staples, etc. in the storage section 6, after fully closing the frame 2 and handle 3, place your fingertip on the finger hook 28 at the tip of the punch table 10 and open it upward. Can be taken out easily.

Next, in the second embodiment shown in FIG. 6, there is only one pivot point provided at the rear base end of the frame 2, and shaft holes are bored at the rear base ends of the base 1 and the handle 3, respectively. The handle 3 as well as the base 1 is pivotally connected to the pivot portion 19 of the frame 2 via a shaft 30.

For this reason, the punch blade 17 is installed so that the pivot portion 19 is positioned along the rear extension line of the cutting edge line of the cutting edge 16 and the upper limit position line of the portion where the punch blade 17 moves in and out of the punch hole 12. , the mounting portion 31 on the lower surface of the frame 2 is formed so as to be partially inclined as shown in FIG.

In this second embodiment, since the punching work is performed by operating the handle 3, a locking body 32 for locking the frame 2 and the handle 3 in relative positions is rotated in the front of the handle 3. Installed as possible.

Next, in order to perform paper binding work according to this second embodiment, the sixth
As shown in the figure, if you press the handle 3 with the lower part of the hook 3 shifted to the right in the figure, you can staple the paper like a conventional stapler, and you can also use it as a punch to make holes. If so, move the lower part of the hook 32 to the left to the position indicated by the dotted line, and then press down on the handle 3.
Since the lower part of the hook 32 engages with the upper surface of the front end of the frame 2, the punch blade 17 descends together with the frame 2 while the handle 3 and frame 2 are hooked, and punches the paper inserted into the insertion slot 9. It can be performed.

In the first embodiment, the base and the frame are pivotally connected by providing a pivot on the base and forming a shaft hole in the frame. In addition, in the second embodiment, the hook 32 is provided inside the handle, but the structure and attachment method of the hook 32 are not necessarily limited to this. , any structure may be used as long as it allows the frame and handle to be engaged and released.

As described above, the present invention can reliably and separately perform paper binding and punching even on thin paper with a single unit, so there is no need to separately provide a puncher and a stapler, resulting in cost savings and improved office efficiency. It has extremely significant advantages and effects, such as being easy to measure, easy to manufacture and assemble, and inexpensive because it has a simple structure and a small number of parts.
