Description

[Detailed Description of the Invention] The present invention relates to a device for removing pushpins attached to the ceiling.

Traditionally, in various shops such as department stores and supermarkets, headlines are hung from the ceiling with thumbtacks in order to hold special sales of various products, events, etc., or to display products. A stepladder, etc. was required to remove it, and since it was time-consuming to remove it, only the heading paper had to be torn off and removed, leaving the thumbtacks fixed to the ceiling, which was very unsightly.

Also, when removing thumbtacks, the work is done while standing on a stepladder, so
During this process, thumbtacks fall off the floor and scatter in unexpected directions, and it takes a lot of effort to collect them. An unexpected minor accident was caused by a thumbtack left behind.

The present invention provides a thumbtack remover that can easily remove thumbtacks without using a stepladder and does not cause the thumbtacks to fall and scatter on the floor.
An embodiment of the present invention will be explained with reference to the drawings.

At the tip of the band pipe 1, both side walls 3 are integrated with a fixing part 2 which is externally fitted and fixed to the pipe 1, and protrude laterally from the fixing part.
a, 3a and a bottom plate 3b that slopes downward into the band pipe 1.
An arm main body 3 is provided, which is rotatable in the direction of bringing the removal main body 5 closer to the fixing part 2 by holding a bolt nut 4 at the tip of both side walls 3a, 3a of the arm main body 3, and The side surface of the lower end is vertically supported along the tip surface of the bottom plate 3b which is inclined downward.

(See Figure 2) The upper surface of this removal main body 5 is formed into an inclined protruding surface 6 upward toward the extension line of the band pipe.
The protruding surface portion is formed with a split nail 7 having a groove 7a in the center into which the needle of the thumbtack fits.

It is preferable to form the tip of the nail with a thin wall 7b because it facilitates removal of the thumbtack.

Reference numeral 8 denotes a spring that elastically biases the removal main body 5 in a direction away from the fixing portion 2, using the pivot support of the removal main body 5 supported by the bolt and nut 4 as a fulcrum.

Although the illustrated band pipe 1 is a single piece, several pipes may be joined together using appropriate means such as screws or nuts, or several pipes may be made expandable and contractible by employing known expansion and contraction means. Needless to say, it may be formed.

Reference numeral 9 indicates a cap detachably fitted onto the band pipe 1.

Since the present invention is constructed as described above, when removing the thumbtack left on the ceiling, the tip of the two-way cut 7 part of the removal main body 5 in the state shown in Fig. 2 is attached to the tip of the thumbtack left on the ceiling. Press it along the outer circumferential surface, and hold the band pipe 1 and push it up from below.

Then, the removal main body 5 rotates against the spring 8 in the direction of bringing it closer to the fixing part 2 as indicated by the arrow, using the bolt/nut 4 retaining part rotatably supported as a fulcrum.

However, since a pushing force is always acting on the removal main body 5 from below, the rotational force using the bolt/nut part 4 as a fulcrum acts as a horizontal moving force along the surface of the ceiling, and the bifurcated claws are attached to the ceiling. The nail moves horizontally (in the lateral direction) between the thumbtack and the ceiling surface, and the nail is pushed between the ceiling surface and the thumbtack.

By this pushing, the needle portion of the thumbtack B fits into the groove 7a of the split claw 7, as shown in FIG.

After the needle part of the thumbtack fits into the groove 7a in this way, when the band pipe 1 is pulled downward, a downward pulling force is applied to the head of the thumbtack by the split claw 7, and as a result, the thumbtack is lifted from the ceiling. It comes off.

The thumbtack that comes off from the ceiling falls into the arm main body 3.

Since the bottom plate 3b of this main body of the arm is inclined downward into the band pipe 1, the thumbtack naturally falls into the band pipe and falls to the bottom of the pipe.

As described above, at the same time as the thumbtack is removed, the removal main body 5 is immediately rotated in a direction away from the fixed part 2 by the elastic force of the spring 8, and its lower end comes into contact with the end of the bottom plate 3b, as shown in FIG. Return to the original state shown in , and prepare for removing the next thumbtack. By repeating the above operations as shown in , you can remove the thumbtacks one by one.
stored in the bottom of the body.

After removing all the thumbtacks, the bottom cap 9 is removed, and the thumbtacks are taken out from inside the band pipe at once.

As mentioned above, by using the device of this invention, thumbtacks attached to the ceiling can be easily and reliably removed without the hassle of conventional methods, and when removing the thumbtacks from the ceiling, the thumbtacks scatter in all directions. This provides a convenient thumbtack remover that does not cause any risk of damage.
