The present invention is provided with a bottom part made of a flexible gaseous material, which is formed of a paper scrap, and is disposed to be movable to face the bottom part, and is provided with a front side stop member such as a punching paper, and is elastically flexible at various positions. It is about a paper punch with a T-shape that can be paused.

In this type of paper punch, in order to empty the paper scrap container used as the support surface for punching, it is separated from the lower abdomen of the punch, or partially clicked and opened. The bottom of the paper scrap is made of a relatively flexible, flexible plastic material to facilitate the removal or opening of the paper scrap and to allow the document punch to rest on it as much as possible without slipping on the support.

In known paper punches of this type (DE-OS 3740425), the T-shape is guided directly into a rectangular passageway open to both sides of the bottom and molded into a corresponding bin recess provided in the transverse wall of the rectangular passageway. It is engaged by the idle iron part. However, because the inner wall reinforcement of the rectangular passage is different, the horizontal wall that is easily bendable when the recessed iron passes between several recessed recesses is unevenly bent, which causes a different magnitude of resistance to move the T-shaped ruler. . In addition, the recessed part can not be heard from the side wall made of flexible plastic material, and especially when the T-shaped part is pushed in quickly, it cannot be sensed whether it is in the recessed part. There is a danger that the hole in the paper may be out of position by pushing it in.

Therefore, the object of the present invention is to improve the known paper punch to ensure that the T-shaped uniformly and feel in all the rest position.

This problem is solved by the features of claim 1. Still other suitable structures of the invention are described in the claims dependent.

The present invention makes it possible to easily feel the uniform strength even when the T-shaped ruler and the bottom are bonded by suitable material pairs or structures in the rest area, but do not impair the slip stability of the attachment surface and the detachability of the bottom. It is. According to the present invention, the T-shape can be guided into a rest member which can enter the cutout of the bottom and can be fixedly immobilized within the cutout, and can be rested by such a restraint member at various positions.

In order to reduce the friction between the T-shaped ruler and the rest member, thereby increasing the life of the T-shaped ruler and the rest member, the T-shape of the rest member has different strengths and is made of a harder plastic material than the bottom plastic material. . It is preferable that the rest member is made of a plastic material that is more rigid than the plastic material of the T-shape. Polyoxymethylene (POM) is selected as a suitable material combination for the resting member, and a modified plastic roll is selected as a material combination of the T-shape.

In a suitable structure of the present invention, the T-shaped cross section suspended in the rest member is adjacent to the bottom of the rest member having a U-shaped cross section by the lower edge of the side wall, and rests the rest member by the outer surface of the side wall. It is against the inner surface of the side wall. In another structure of the present invention, the material bridges may be elastically deformed in the transverse direction with respect to the side wall surface on the sidewalls of the resting member, and are separated from the bottom of the resting member by the through opening extending in the longitudinal direction. There is provided a recessed convex portion formed on the inner surface. This through opening is limited to the outside by the inner surface of the side wall extending to the lower side of the bottom of the rest member. Since the rest iron is arranged on the material bridge, the length of the through opening can be optimized when the T-shaped ruler, the rest member and the material combination are given, thereby optimizing the spring force or the elasticity of the rest coupling.

It is preferable to provide the recessed recessed portion in which the T-shaped gyro sidewall can engage the recessed recessed portion formed on the material bridge of the recessed member on its outer surface.

In another suitable structure of the present invention, the rest member is provided with two shoulders protruding over the outer surface of the side wall of the rest member on its outer front face toward the stop member of the T-shape, which shoulders are provided at the bottom of the bottom of the rest member. Protruding over the side, the slope and steep backside may be secured in the bottom without play by at least one resting protrusion provided. In the assembled bed, the rest member is opposed to the recess end in the bottom by the rear surface of the rest projection, and the shoulder is abutted against the outer wall of the bottom.

In another suitable structure of the present invention, when the resting projection adjacent the recess edge in the bottom protrudes over the upper end of the sidewall of the resting member in the region of the resting projection, the bottom material is fixed when the resting member is fixed. It is held in position by at least one supporting convex adjacent the bridge.

In order to prevent the finger from being pushed between the stop member and the paper punch when pushing the T-shaped ruler, a stopper is formed on the upper side of the bottom of the stop member, and the stopper is formed on the stop member side of the T-shape. (1) The side walls of the T-shape are joined within the recessed recesses, and they face each other in the bar arranged at regular intervals from the stop member. At this time, the stopper can be disposed on the front surface of the rest member facing toward the stop member.

In another suitable structure of the present invention, in the material bridge area, the upper surface of the bottom of the resting member is formed in the material bridge area so that the entirety is not easily drawn out when the T-shape is pushed out, and the rest recess is provided on the pushing side of the T-shape. The rest member is provided in the rest member against the front side wall on the pushing side of the T-shape in the first rest recess. It is preferable to incline the pushing front surface of the stopper to prevent the two stopper formed on the bottom of the rest member from being broken when the T-shaped is completely pulled out.

In another suitable structure of the present invention, the T-shaped pairs face each other in a top end region of the side wall of the pause member upwardly in the rest member, protrude inwards, and engage at least two guide ends of the T-shape. It is held and guided by more than one guide convex. Here, it is desirable to provide two guide pairs of iron arranged on the material bridge at regular intervals from each other.

In order to prevent the T-shaped self from being caught in the cutout or the retracting opening of the cutout that is opposite the resting member, it is desirable to provide the T-shaped slope at the front end at its end opposite the stop member.

An embodiment of the present invention is shown in more detail by the accompanying drawings as follows.

The document punch bottom portion 10 shown in FIGS. 1 and 2 is capable of resting from below on the lower member of the document punch (not shown). This lower member forms a paper scrap 12 and is used by the bottom 13 as a non-slip attachment surface for punching a document. In the cutout portion of the bottom portion 10 formed as the rectangular passage 14, the rest member 16 is fixed so as not to move. In the rest member 16, a T-shaped arm 18 having a stop member for a document to be punched can move, and can be rested at various positions according to different paper dimensions.

The back portion of the bottom 10 forming the paper scraps 12 may be clicked and secured around the bend side 21 of the lower punch, and the back side may be suspended in the bend side 21 region. 22 'and 22 "are provided. The paper scrap barrel 12 is provided with an operation member 24 formed in a key shape in the area of the rear end 23, which operation member is to be separated at the bottom of the punch. The two pedestals 26 allow the paper pieces to be filled in the paper scraps 12 from the outside.

The front part of the bottom part 10 is provided with partition walls 30 and 32 which extend parallel to the front end 28 and are arranged at regular intervals from each other. 13, and are joined to each other by material bridges 36, 38, 40, 42, and 44 at the upper and lower ends thereof, and the material bridges 36, 38 between the upper ends of the partitions 30, 32, respectively. ) Are disposed transversely in the longitudinal direction against the material bridges 40, 42, 44 between the lower ends of the partitions 30, 32. Another two in the area of the side wall portion 22 "are provided. The material bridges 46 and 48 are bounded by two openings on the front side of the rectangular passage 14 formed by the partition wall and the material bridge. The reinforcing ribs 50 disposed on the outer surfaces of the partition walls 30 and 32 are used to harden the inner surface of the rectangular passage 14.

The resting member 16 shown in FIG. 5A which can be fixed in the rectangular passage 14 is provided with a U-shaped cross section, which is provided with two sidewalls 52,54 and these sidewalls 52,54. It is composed of one toilet member bottom 56 for coupling. On its outer surface, facing toward the stop member 20 of the T-shape 18, two shoulders 60, 62 are provided in the pause member 16 which protrude above the outer surfaces of the pause member side walls 52, 54. And in the opposing inner front regions are provided two resting projections 68 which project over the lower side of the bottom of the rest member 56 and are provided with a slope 64 and a steeply inclined back side 66. have. It is composed of a relatively rigid plastic material, in particular polyoxymethylene (POM) so that the resting member 16 can be guided into the rectangular passage 14 together with the T-shaped 18 and fixed thereto. The shoulders 60 and 62 are adjacent to the side wall 22 ″ of the bottom 10 after assembly, and the rear side 66 of the resting projection 68 engages the inner edge of the material bridge 42. As a result, the rest member 16 is fixed to the rectangular passage 14 without play, and the supporting concave portion 70 protruding above the upper end of the rest member side walls 52 and 54 in the region of the rest projection 68 is The material bridge bends slightly upward while being placed against the lower side of the material bridge 36. By the elastic reaction force of the material bridge 36, the supporting concave portion 70 and the resting protrusion 68 are pressed downward. The height of the rear side 66 of the resting projection 68 is almost the same as the thickness of the material bridge 42, so that the height of the rear side 66 of the resting projection 68 is the material bridge 42. Because the thickness is approximately equal to, the resting projection 68 extends beyond the attachment surface of the bottom 10. It does not protrude.

The T-shaped arm 18 shown in FIGS. 4A to 4D is provided with a substantially U-shaped cross section, and the bottom 56 of the resting member is formed by the free ends 72 of the side walls 74 and 76. The outer surfaces 78 and 80 are adjacent to the inner surfaces of the pause member side walls 52 and 54. The T-shape 18 is disposed at regular intervals in the upper edge regions of the side walls 52 and 54 of the rest member, and the convex portions projecting downwardly engage the guide groove 58 provided in the T-shape 18. It is held in the guide member by two guide convex pairs 59 and 61. The T-shape 18 is made of a softer plastic material (eg, modified polystyrene) than the rest member 16. Since the friction of the side surfaces facing each other is reduced by the hardness difference between the T-shape 18 and the rest member 16, the life of the two members can be extended.

The rest member 16 is provided with two rest recesses 82 and 84 formed on the inner surface of the side walls 52 and 44 so that the T-shaped ruler 18 can rest. These are engaged with one of the recessed recessed pairs 85a, 85b, 85c, 85d, 85e, 85f formed in the sidewalls 74, 76 of the T-shape 18 at a given interval outwardly. To rest the side walls 52 and 54 of the rest member 16 at all times by two through openings 86 and 88 extending in the longitudinal direction in the region of the rest recesses 82 and 84. Separated from the bottom of the member, these through openings are limited in scope by the inner surfaces of the side walls 52 and 54 extending outward to the bottom surface of the bottom of the rest member 56. At this time, the material bridges 90 and 92 formed inside the side walls are formed from one of the recessed recessed pairs 85a, 85b, 85c, 85d, 85e and 85f when the recessed convex portions 82 and 84 move the T-shaped ruler. As soon as it is pulled out, it can be bent outwards. When the material of the rest member is given, a spring for moving the rest portions 82 and 84 drawn out from the rest portion when the T-shape 18 moves is adjacent to the side walls 74 and 76 is provided with a resilient through opening ( It can be adjusted by the length of the 86,88 and the height and the wall width of the side wall member 52,54.

A stop convex 94 is formed on the upper side of the bottom of the stop member to prevent a finger from entering between the stop member 20 and the lower punch when moving the T-shaped arm 18. When the convex portions 82 and 84 rest in the first pair of recessed recessed portions 85a on the side of the stop member, they are arranged at regular intervals from the stop member 20, and the side walls 74 of the T-shaped rule 18 are formed. It is against the partition 96 which couples 76 (FIG. 2).

The first resting recess 85f on the side where the resting recesses 82 and 84 are pushed by another stopping recess 98 protruding upward from the bottom of the resting member in the region of the resting recesses 82 and 84. At rest, the T-shaped chair 18 is against the front side wall 100 on the pushing side of the T-shaped chair 18 so that the T-shaped chair 18 cannot be pulled out at all. Since the front surfaces of the two stop convex portions 94 and 98 are inclined, the T-shape 18 can be pulled out if necessary without destroying the stop convex portions 94 and 98. When pulling out the T-shaped ruler 18, the end of the T-shaped ruler on the side where the front side wall 100 is pushed up is slid over the slope of the stopper 98 or 94.

At the end of the T-shaped ruler 19 opposite the stop member 20, a slope 102 inclined toward the front side wall 100 is provided, and the slope has a rectangular passageway at the side where the T-shaped ruler 18 exits. It is easy to be guided into the opening of 14) and the T-shaped 18 is pressed upwards against the material bridge 48 and is fixed between the bottom 10 and the lower punch.
