JP2010216645A - Bellows spring surrounding on under surface of head part of push-locking pin - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a push-locking pin for preventing a pin body from being bared, and capable of maximally straightly piercing, by covering a clearance easily generated by a pin body between boards and itself in its pierced-in use state, in the push-stop pin composed of a head part and the pin body. <P>SOLUTION: This bellows spring is formed of the head part 1, the pointed-shaped pin body 2 having integrally the proper length on an under surface of this head part 2, and an expandable elastic body 3 for surrounding the pin body 2 on the under surface of the head part 1. When suspending by piercing this pin body 2 in boards 6 such as a wall and a bulletin board by piercing the pin body 2 in paper such as a memorandum and a poster by pressing the head part 1 by fingers, the clearance with the boards 6 is covered when the surrounded expandable elastic body 3 contracts in response to a piercing-in state. Alternatively, easy falling-off/dropping from the boards and the bulletin board 6 can be prevented by installing a spiral pin body. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a pressing pin used to suspend a document, paper or the like on a board such as a wall or a bulletin board.

  2. Description of the Related Art Conventionally, a thumbtack composed of a head and a pin body or a holding pin simply referred to as a pin has been widely used in companies and homes for storing and organizing notes and various papers.

  These retaining pins are made of plastic or metal to pierce and hold various types of paper such as memos, calendars, posters, etc. and hang them on boards made of wood or plywood, or boards such as bulletin boards. A head made of steel and a pin-like pin body having an appropriate length on the lower surface of the head are integrally formed.

  Furthermore, since the length of the pressing pin body is different, the bellows spring of the pressing pin body is provided with an elastic bellows spring body that can be expanded and contracted according to different lengths of the pressing pin body.

  In addition, the base part of the elastic bellows spring which can be expanded-contracted is fixed to the surroundings of the lower surface of the head part of a pressing pin body with an adhesive etc., and it is used integrally.

  However, this type of conventionally used retaining pin is rarely inserted into a board, such as a wooden or plywood, into which the pin body is inserted, and many of them have a gap between them. It was happening.

  There are various factors that can cause a gap, such as the board is hard and the pin body is not sufficiently inserted, the finger pressure on the head is insufficient, the pin body is inserted diagonally, etc. The fixing pin was removed, and various papers were peeled off due to wind pressure and weight.

  It is an object of the present invention to cover a gap that is likely to be generated between a pin body and a board in a use state where the pin body is inserted, and the pin body is exposed. It is intended to provide a push pin that can be pierced as straight as possible.

  In order to achieve the above-described object, a press pin according to the present invention is a press pin in which a pin body of an appropriate length is integrally provided on the lower surface of the head, and surrounds the pin body on the lower surface of the head. A stretchable elastic body is provided.

  Furthermore, the elastic body is a bellows spring.

  Further, the holding pin is fixed to the periphery of the lower surface of the head and the base portion of the elastic bellows spring with an adhesive or the like.

  According to the holding pin according to the present invention having the above-described configuration, an elastic body that can stretch and contract the pin body is provided on the lower surface of the head, and the paper or the like is pressed and covered on the boards to be exposed. Therefore, the pin body can be held without being loosened or detached due to external factors such as wind pressure.

  In addition, it is possible to prevent the limbs from being injured at the tip of the pin body when the papers are suspended from the boards, or when they are accidentally dropped.

  Furthermore, by using a bellows spring as an elastic body that can be expanded and contracted to surround the pin body, the pin body can be pierced without preventing the pin body from being lowered, and sufficient strength can be maintained.

  Alternatively, by using a bellows spring as a stretchable elastic body that surrounds the pin body, an appropriate concave spiral shape is formed on one pin body, and the head of the pin body is held on a board, bulletin board or the like. Can be easily prevented from falling off with respect to the stretching force of the bellows spring of an elastic body that can be expanded and contracted.

  It is sectional drawing which showed the attachment state of the pressing pin which concerns on this invention.   It is the side view which showed shrinkage | contraction to the bellows spring of the press pin which concerns on this invention.   It is the side view which showed expansion | extension to the bellows spring of the holding pin which concerns on this invention.   It is the schematic which showed the example of attachment of the press pin which concerns on this invention.   It is the bottom view which showed the bellows spring of the pressing pin which concerns on this invention.   FIG. 3 is an enlarged schematic view showing a spiral shape of a spiral pressing pin according to the present invention.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a holding pin according to the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, a pointed shape having an appropriate length integrally with a lower surface 4 of a head 1 made of hard plastic or metal. It is formed from a stretchable elastic body 3 surrounding the pin body 2.

  This holding pin is used to apply pressure to the head 1 to pierce the pin-like pin body 2 into a sheet 5 such as a memo or a poster, and to insert the pin body 2 into a board 6 such as a wall or a bulletin board. When suspended, the elastic body 3 that can be expanded and contracted contracts to cover the gap with the boards 6 in accordance with the state where it is inserted.

  As shown in FIG. 1, the elastic body 3 that can be expanded and contracted mainly uses a hard vinyl chloride synthetic resin bellows spring 3 a and is integrated with the lower surface 4 of the head 1 so as to surround the pin body 2. The bellows spring 3a is extended so that the pin body 2 slightly protrudes when not in use.

  In addition, as shown in FIG. 2, an expandable / contractible bellows spring 3a is provided on the surrounding surface of the lower surface 4 of the head 1 so as to surround the holding pin body 2, and the holding pin body 2 is used in a wall or a bulletin board in use. FIG. 6 is a side view of the bellows spring 3 contracted following the piercing of the like 6 and the like.

  Further, as shown in FIG. 3, an expandable bellow spring 3 a is provided in the surrounding of the lower surface 4 of the head 1 so as to surround the press pin body 2, and the press pin body 2 of the elastic body 3 that can expand and contract. FIG. 4 is an extended side view of the bellows spring 3a before use.

  Further, as shown in FIG. 4, the elastic body 3 that can be expanded and contracted is a hard material in which the pin body 2 is pierced through the head 1 with acupressure and various types of paper 5 such as a calendar and a poster are inserted into a board 6 such as a wall or a bulletin board. The bellows spring 3a made of a vinyl chloride synthetic resin.

  FIG. 5 is a bottom view of the stretchable bellows spring 3a, which is a stretchable elastic body 3 attached to the lower surface 4 of the hold-down pin body 2, with the tip of the hold-down pin body 2 positioned at the center.

  Alternatively, in FIG. 6, a single pin body 2 is formed in a spiral shape 7, and a board, a bulletin board 6, a poster, a calendar 5, etc. are inserted and fixed while pushing the head 1 of the holding pin body. 4 is an enlarged schematic view of a spiral pin body 8. FIG.

  The elastic body 3 has been described as being integrally provided on the lower surface 4 of the head 1 so as to surround the pin body 2. However, the present invention is not limited to this, and the pin body 2 is detachably inserted. Also good.
