Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stapler used to staple documents.

Traditional staplers only have needles that run perpendicular to their axis. Therefore, even if the needle is placed at the center fold line of the document, the distance from the left and right sides is often too large to reach the desired position.

Therefore, this invention allows the stapler to be inserted not only in a direction perpendicular to the axis of the stapler, but also in a direction parallel to it.

The purpose is to solve this ff[.

To explain the invention based on an embodiment shown in one drawing, this stapler has upper and lower jaws 15, 17 which are pivotably connected to each other by a pin 13 and can be opened and closed, and upper and lower jaws 15, 17 which can be opened and closed are also pivotally connected to each other by a pin 19. Consisting of a freely adjustable magazine 21 and rod 23 1
The magazine and rod are the first. It can be placed in two positions: inside the upper and lower jaws as shown in Figure 2, and 90 degrees outside the jaws as shown in chain lines in Figure 2 and Figure 5. , a rod 23 is pivotally supported under the upper jaw 15 by a pin 25. In order to hold the magazine and rod in either of these two states, the upper jaw 1 is
A rotation stopper consisting of four protrusions 27 is provided on the lower surface of 5. This small protrusion holds the rod 23 in either of the above two states from both sides to suppress its rotation, and if a force exceeding a certain value is applied, the rod will move over the small protrusion. Can be rotated in any direction. In this embodiment, one magazine and rod can be swung out to either the left or right side of the jaw, but it is also possible to swing out only to one side.

The magazine 21 has a substantially U-shaped cross section, and a series of needles 29 are stored therein. This needle, like the conventional one,
They have a U- or U-shaped cross section and are weakly connected to each other. A rod 31 runs vertically inside the magazine 21, and a coil spring 35 is placed along this rod.

A series of needles 29 is forced forward via a feed 33 sliding along the rod. 37 is an elongated slit opened just below the front side, and is large enough to allow only one needle to pass through it.

The rod body 23 is formed in a U-shaped cross section, and a projecting piece 39 is attached to the lower front surface. This protrusion has a size and position that allows it to abut the foremost needle of one magazine and push it out of the slit. In addition, the above-mentioned bottle 25
is located at the center line of this protrusion.

A plate 45 is attached to the bottom of the center of the rod.
Its tip abuts against the edge of the magazine 21 and urges it downward. In order to support the magazine thus biased by the rod, a bulge 43 is formed in the center of one magazine, and a pair of small protrusions 41 that engage with this are provided on the inner side of the rod. Of course, if you apply an appropriate amount of force, /11
The magazine can be opened by disengaging the protrusion from the ampulla.

A pedestal 47 is integrally formed at the front of the lower jaw 17 and is sandwiched between the pedestal 47 and the protruding piece 39 to bend the needle.

This base is provided with a guide groove 49 so that the needle can be properly bent inward. This guide groove is designed to allow the first magazine and rod to swing out of the jaw by 90 degrees, so it is formed in a cross shape compared to the conventional shape, as shown in Figure 3.

In use, if you want to close the document 51 near the edge as shown in FIG. Magazine 2 as shown in Figure 2.
1 and the rod 23 are housed inside the upper and lower jaws 15 and 17. Also, when closing the center fold line 53 as shown in Figure 6 (B), since it will not be possible to reach it if you operate from the left and right sides of the document, swing the magazine and rod 90 degrees out of the jaw as shown in Figure 2. (Chat line, FIG. 5), bring the tip of the stapler 11 to the desired position so that the needle is on the center line of the jaw, and the nearest side (L side or bottom side) is pinched.

After setting the stapler in this way, the document is stapled by pressing down on the jaw 15. At that time, the action of the stapler is that the 9 magazine and the rod are in either of the two states. It's like that. That is, if you lower the upper part by one river, the first. 9 magazines 21 as shown by chain lines in Figure 5.
comes into contact with the document 9, then the spring 45 bends and the protruding piece 39
descends. This descending protrusion abuts the f# front needle 29 in the fourth magazine 21, separates it from the other needles, and pushes it out through the slit 37. The extruded leg of the needle pierces the document 51, reaches the base 47, is guided by the cross-shaped groove 49, bends inward, and collapses. In addition, the guide groove 4
9 consists of two intersecting straight grooves.

When the magazine and rod are inside the jaw, there is only a straight groove perpendicular to the center line of @, and when the magazine and rod are swung out of the jaw, there is only a straight groove on the center line only works.

After the document is written in this way, when the force applied to the upper jaw 15 is released, the protrusion 39 comes out of the magazine 21 due to the force of the spring 45, and the needle is sent after it by the action of the spring 35 to the next needle. Prepare for use.

Although not provided in this embodiment, springs may be provided to keep the upper and lower jaws open at a certain angle.

Improves operability.

In this way, the stapler of this invention can insert the needle not only in the direction perpendicular to the axis, but also in the direction parallel to it.

Therefore, there is an effect that the needle can be applied over a wide range on the document.
