Abstract

PURPOSE:To stable hold an extracted staple on a wedge like part at all times, by providing a slit for entering the medium side of the staple between a projection and an oblique side. CONSTITUTION:The meddle side of a staple in the staple removing process comes into slits 13a, 13b, 14a, 14b. So the extracted staple is stably held on wedge like parts 9a, 9b, 10a, 10b, while both movable legs 7, 8 interval is spread. Specially due to there being projections 11a, 11b, 12a, 12b and sits 13a, 13b, 14a, 14b on both movable parts 7, 8, the action extruding forcibly the staples inside the slits 13a, 13bn 14a, 14b is exerted with the crossed position of the slits 13a, 13b, 14a, 14b and the tips of the projections 11a, 11b, 12a, 12b being descended together in the process that both movable legs 7, 8 interval is spread. So the extruded staple is carried to the specified place just as holding the extruded stale, and can be surely dropped there.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a circumferential staple tool for removing staples attached to pieces of paper or the like.

BACKGROUND OF THE INVENTION A conventional circumferential stapler device shown in FIG. Parts 4a, 4b, 5
a, 5b. Since movable #2.3 has flexibility, when it is strongly pinched between fingertips, the distal edges of the opposing wedge-shaped portions 4a, 5a and 4b, 5b overlap with each other. Therefore, a wedge-shaped portion 4a + 5 is formed between the piece of paper and the stapler attached to it.
When g + 4 b and 5 b are inserted from their leading ends, the stapler is pulled out while expanding both folded sides.

Problems to be Solved by the Invention However, the staples removed in this way,
It does not necessarily straddle the wedge-shaped part, but in many cases,
The moment it is pulled out, it scatters due to its own splashing action. For this reason, there is the trouble of having to pick up and throw away the staples that have been pulled out. In addition, even if the stapler that has been pulled out is sitting on the wedge-shaped part, a certain level of caution is required to throw it away without dropping it.

Means for Solving the Problems In the needle remover according to the present invention, at least one movable leg includes:
A protrusion is provided along the oblique side of the wedge-shaped portion, and a slit is provided between the protrusion and the oblique side for inserting the intermediate side of the stapler.

Function: With the needle remover configured as described above, the intermediate side of the stapler enters the slit during the needle removal process, so the removed stapler remains in a (rust-like) state until the distance between the two movable legs is widened. In particular, by providing both movable legs with protrusions and slits, as the distance between both movable legs widens, the intersection position of both slits and the tips of both protrusions will both lower and close to the slit. Since the inner stapler is forcibly pushed out, the removed stapler can be held and carried to a predetermined location, where it can be dropped securely.

Embodiments Next, the present invention will be explained in detail with reference to embodiments shown in the drawings.

The needle remover of the embodiment shown in FIG. 1 has a pair of movable legs 7.8 extending from the fixed part 6, and a pair of wedge-shaped parts 9a sharply protruding toward the opposite stool from the respective free edges; 9b, 10
a, 10b, and protrusions 11a, 1lb, 12a, 12b protruding along the oblique side of this wedge-shaped portion.
and a protrusion 11a.

1 lb, 12a, and 12b form slits 13a, 13b, 14a, and 14b for inserting the middle side of the stapler between the corresponding oblique sides.

Since both movable legs 7.8 have flexibility, when they are pinched between the fingertips, as shown in FIG. are overlapped with each other, and the slits 11a and 1
2a, 11b, and 12b intersect each other to form a small hole.

As shown in FIG. 3, wedge-shaped portions 9a and 10a are wedged between the paper A and the stapler B attached thereto.
and 9b, 10b pull up the middle side of the stapler B. This state is maintained even after the stapler B is removed until the distance between the movable legs 7 and 8 is widened. Therefore, the stapler B does not fly away due to its own spring action when it is removed.

Then, as the distance between the movable legs 7.8 is increased, the intersection position of the two slits forming one small hole is lowered, and the protrusions 11a, 11b.

The respective tips of 12a and 12b descend to push out the staple B. Therefore, if such opening operation is performed at a predetermined position, the stapler can be reliably dropped at that position.

In the embodiment described above, both movable legs 7 and 8 are provided with protrusions and slits, but the protrusions and slits may be omitted for either one of the movable legs. Further, the protrusion and slit formed on one of the movable legs may be a single wide protrusion as shown in FIG. 4. In this case, the wedge-shaped portion 9 serves as a pair of wedge-shaped portions 9a and 9b, the protrusion 11 provided along the oblique side of the wedge-shaped portion 9 serves as a pair of protrusion 11a and 11b, and the slit 13 serves as a pair of protrusions 11a and 11b. It plays the role of a pair of slits 13a and 13b.

In the embodiment shown in FIG. 5, a pair of movable legs 7.8 are pivoted about a shaft 15. In this case, the spring 16
Therefore, there is no need for the movable legs 7, 8a to have flexibility. Further, in the embodiments shown in FIGS. 6 and 7, a pantograph-shaped extension region 17 is provided at a position beyond the pivot point of the shaft 15, and this extension region 17
is the operating section. Although the illustrated extension region 17 is generally rounded, it may also be angular or have a cover, in which case the second, third and fourth pivot points 18 Since the lever action is exerted by .19 and 20, both movable legs 7 and 8 can be opened and closed with a relatively weak force.

Effects of the Invention As described above, according to the present invention, removed staples can be stably held on the wedge-shaped portion at all times, thereby eliminating the trouble of picking up and discarding scattered staples. Furthermore, by providing both movable legs with projections and slits, the stapler in the slit can be forcibly dropped during the process of widening the distance between the two movable legs.
