Abstract

<P>PROBLEM TO BE SOLVED: To provide a lightweight thumbtack driver which can continuously drive thumbtacks into a board or the like by extruding the thumbtack forward from a magazine by a spring and depressing a handle part. <P>SOLUTION: This thumbtack driver comprises a holder which accommodates a magazine capable of being refilled with a string of the thumbtacks, in a freely detachable manner; an extruder with a spring part composed of an extrusion piece fitted to a sliding plate so as to allow the forward extrusion of the thumbtacks one by one; and a forcing device with a forcing rod, for driving the thumbtack into the board or the like, which is attached to the tip part fixed to the holder in a freely opening way. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a thumbtack that can automatically push out thumbts one by one and manually drive them.

As conventional techniques, a cylindrical main body in which a plurality of pushpins having rod-shaped heads connected in the width direction are slidably inserted, a punching guide for punching out individual pushpins provided at the tip of the cylindrical main body, and a punching guide A piston for launching a thumbtack on the head side of the head, a launching lever attached to the rear part of the piston and provided with an automatic return means, a thumbtack replenishing port provided at the rear end of the cylindrical body, and opening and closing the thumbtack replenishing port There is a thumbtack launcher characterized by having a lid. (See Patent Document 1)
JP-A-9-207498 (Claim 3, FIG. 4)

However, the thing of the above forms must use a dedicated thumbtack (rod-shaped head), and when the thumbtack is cut, it can only be purchased at a specialty store, and the work may stop.
In addition, since it is a dedicated thumbtack, the cost is high, and since the head is a stick, it cannot be used for posters or banners with heavy weight. (There is a risk of tearing)

  The present invention has been made in view of the above-described problems, and is a lightweight type pusher that can be attached to a board or the like continuously by pushing the thumbtack in the magazine forward with a spring spring and pushing the handle part. The purpose is to provide.

  As means for solving the problems, a holder for detachably storing a refillable magazine comprising a plurality of pushpins connected in series, and an extrusion piece on the slide plate to push the pushpins forward one by one. And a pushing tool provided with a pushing rod for attaching a thumbtack to a board or the like at a tip provided on the holder so as to be freely opened and closed. The spring part is a spring spring. Furthermore, the slit part for moving an extrusion piece is provided in a slide plate and a magazine. In addition, a magnet is provided at the tip of the push rod.

According to the thumbtack of the present invention, since it is lightweight, even a woman can easily and easily work, and there is an effect that the thumbtack can be securely attached to a board or the like by pushing the handle part.
In addition, the use of a magazine makes it easy to add or replace a thumbtack, and having a spare allows many operations to be performed at once, thereby improving work efficiency.

1 is a thumbtack striker.
Reference numeral 2 denotes a magazine in which a plurality of thumbtacks G are continuously provided, and is provided with a slit portion 2a on the upper surface and a T-shaped groove 2b.
Reference numeral 3 denotes a holder for inserting and storing the magazine 2 from above and having a substantially U-shaped cross section.
4 is an extruding tool, and a flat plate-like extruding piece 4b1 (corresponding to the slit portion 2a) is formed at the tip of a slide plate 4a formed with a long groove 4a1 that can be inserted and removed in the horizontal direction above the magazine 2. A spring portion 4b, which is a provided spring, is provided, and a stopper 4c for preventing the magazine 2 from being detached is provided at the rear portion.
5 is a pushing tool provided with a pushing rod 5a provided with a magnet 5a1 at the tip thereof, which is provided on the holder 3 so as to be freely opened and closed by a pin P and attaches (presses) a thumbtack G to a board (not shown). A handle portion 5c is provided on the upper portion of the U-shaped frame main body 5b, and a spring spring 5d for rebounding is provided on the back surface.

An example of using the thumbtack 1 configured as described above will be described below.
First, after gripping the handle portion 5c and opening the pusher 5 upward, the pusher 4 is pulled out backward, the magazine 2 is stored in the holder 3, and the pusher 5 is moved downward by grasping the handle portion 5c again. take down.
Subsequently, the lower surface of the holder 3 is pressed against a board (not shown) or the like, and the handle portion 5c is pushed, so that the push rod 5a protrudes and the thumbtack G attached to the magnet 5a1 can be attached (pressed). Is.
Next, when the second thumbtack G1 is attached, the pushing tool 5 moves upward due to the repulsion of the leaf spring 5d, and the pushing rod 5a also moves upward, and at the same time, the pushing piece 4b1 due to the winding force of the spring portion 4b. When the thumbtack G2 is pushed forward, the thumbtack G1 is pushed out, and is attached to the magnet 5a1 in the same manner as described above, and attached sequentially.

In addition, in the said Example, if the shape of each site | part has a similar function, it will not specifically limit.
In addition, the size of the thumbtack and the magazine may be determined as necessary.
