Description

Taka {TACKER}

The present invention relates to a taker, and more particularly, to a taker capable of restricting a trigger of a taker in a locked state to disable a trigger when the takamup is exhausted.

In general, a taka is a tool used to connect or fix two or more objects by continuously injecting nails or staples using air pressure.

Such a taka is widely used in the fields of construction and interior decoration because it is easy to use and can firmly fix and fix the object and improve the working speed.

In other words, work such as joining or fixing wood to concrete block, aluminum chassis, synthetic resin or wood frequently occurs on construction site and indoor interior site, and this operation is important factor for shortening construction period, I am using Taka to proceed.

A typical structure of a taka includes a body in which a piston for generating a power for pushing a takamu while being linearly moved forward and backward by the supply of air is housed and a handle formed at a lower portion of the main body, A magazine installed in the front of the main body and forming a passageway when the thumb nail is fired to the outside, a magazine mounted on the guide and loaded with a plurality of tack nails, And a trigger for actuating the piston to fire the uppermost nail loaded on the magazine to the outside of the guide portion.

An air port is formed in the lower portion of the handle so that a hose or the like can be coupled to supply compressed air for operating the piston provided in the body.

The magazine is formed as a cover slidable on one side thereof so that the lid can be opened and the lid can be closed after attaching the takamail. A spring is provided on the inner lower portion of the magazine so that the takamail can be sequentially pushed up to the guide portion.

And a plurality of takas nails connected to each other in a vertical direction are manufactured in the form of a cartridge, and one takasu cartridge is formed by stacking dozens or hundreds of takas nails connected to each other.

In order to use such a takar, the takamu cartridge is first mounted on the magazine, and then the trigger is pulled in a state in which the tip end portion of the guide portion is in close contact with the connection position of the object to be connected, so that the compressed air flows into the main body and the piston is advanced at a predetermined speed .

With this operation, the topmost nail mounted on the magazine is moved along the guide while hitting the piston, and fired toward the outside of the guide, and is inserted and fixed to the object.

In this way, when the trigger is pulled only, the takamail mounted on the magazine is sequentially fired, so that a quick operation can be performed.

However, when the work is done, even if the takamu is exhausted, the worker often can not easily recognize it.

In other words, since it is difficult for the operator to confirm the remaining amount of the takamail remaining in the magazine, the operator often operates the trigger of the takar while the takamail is exhausted but the operator can not accurately recognize the remaining amount.

If the trigger is pulled while the takamup is exhausted, unnecessary unnecessary scratches are generated on the work surface by the operation of the piston, so that the work surface can not be finished cleanly, and it takes much time to work.

In recent years, in order to overcome such disadvantages, a confirmation window is formed on the magazine so that the remaining amount of the takamail can be confirmed from the outside, but it is difficult for the operator to always confirm it.

In addition, when the worker performs the taka work while checking the remaining amount of the taka nail, it takes a long time to work and the risk of the safety accident is increased.

As shown in the figure, the tacker according to the present invention includes a main body 2 in which a piston (not shown) for generating a linear movement of the air in the forward and backward directions is accommodated, and a knob 4 A guide part 6 installed at the front of the main body 2 and forming a passage when the takam nail is fired to the outside, a plurality of takas nails 100 assembled to the guide part 6, A magazine 8 for sequentially supplying the magazine 8 to the guide portion 6 and a tactile nail 100 mounted on the main body 2 and operated by the piston to mount the magazine 8 on the magazine 8, 6) of the trigger (10).

An air port 12 is formed in a lower portion of the handle 4 to supply compressed air into the main body 2 to operate the piston.

A safety lever 14 is provided on the handle 4 so that the trigger 10 can be operated only when the safety lever 14 is pulled.

The compressed air supplied to the main body 2 is supplied by the operation of the trigger 10. At this time, the piston hits the takam nail 100, and one takam nail is discharged to the outside through the guide part 6, Since the basic structure and operation of the same taker can utilize a technique applied to a conventional taker, a detailed description will be omitted.

In addition, the taka nail 100 used in the taka of the present invention is formed in the form of a cartridge in which each member is stacked like a staple, and one taka cap cartridge is formed by connecting several hundred taka nails together.

The takamail 100 is mounted on the magazine 8 so that the magazine 8 can be housed. The magazine 8 is formed as a cover 16 whose one side can be opened and closed in a sliding manner.

A spring (not shown) is provided on the cover 16 so as to elastically push the hook pin 100 loaded in the magazine 8 toward the guide portion 6.

In addition, an insertion groove 18 is formed at the upper end of the cover 16 so that the support of the trigger lock portion, which will be described later in detail, can be inserted and positioned when the cover is closed.

In the present invention, the trigger lock portion 20 is provided for actuating the trigger 10 in accordance with the remaining amount of the takamh 100 stored in the magazine 8 or for locking the trigger 10 in a locked state do.

A hinge portion 22 is provided under the main body 2 for installing the trigger lock portion 20 and an elastic member 24 composed of a compression coil spring is fixed to the side surface of the main body 2, A hole (26) is formed in the side surface of the trigger (10).

The trigger lock portion 20 includes a latch 30 formed in an orthogonal direction so as to surround a lower portion and a side portion of the main body 2 and formed with a fixing hole 28 to be fitted in the hinge portion 22 of the main body 2, A support table 32 extending from one end of the latch 30 and elastically supported by the upper tack pin 100 accommodated in the magazine 8, One surface of which is inserted and supported between the upper portion of the trigger 10 and the lower portion of the main body 2 and the other surface is supported by the side surface of the trigger 10, And is engaged with the hole 26 formed in the trigger 10 to enable the operation of the trigger 20 when the support base 32 is supported by the thumb nail 100 according to the remaining amount of the nail 100 If the remaining amount of the takamail 100 is almost exhausted and the support base 32 is not supported by the takam nail 100, The trigger includes a locking step (36) for restraint.

The latch 30 is formed with a latching protrusion 38 in which an elastic member 24 formed on the body 2 is inserted and held.

The trigger latching jaw 36 protrudes upward from an end of the extension 40 extending rearward of the lower end of the support plate 34. Therefore, a slight gap is formed between the trigger stopper 36 and the support plate 34 so that the trigger hole 26 can be positioned.

The trigger lock portion 20 is assembled by inserting the fixing hole 28 into the hinge portion 22 and inserting the trigger hook 36 into the hole 26 formed in the side surface of the trigger 10, And a fixing member 42 such as a fixing nut may be assembled to the base 22.

The trigger lock portion 20 thus installed is urged in the direction toward the support base 32 by the outward elasticity of the elastic member 24.

4 and 7A, when the magazine 8 is mounted on the magazine 8, the support table 32 formed on the latch 30 is supported on the upper side of the thumb nail 100, Is kept fully inserted into the hole 26 of the trigger 10 so that the trigger 10 becomes operable.

6 and 7B, when the remaining amount of the takamail is raised up to the upper side of the support table 32, the clasp 30 is pulled up by the elastic force of the elastic member 24, The support base 32 is brought into contact with the inner surface of the magazine 8 in which the takamail is empty, while slightly rotating toward the magazine 8 about the support portion 22. At this time, the trigger latching jaw 36 is also rotated through the hole 26 of the trigger 10, so that the trigger latching jaw 36 is engaged with the upper portion of the hole 26 of the trigger 10 The trigger 10 is restrained and fixed in a state in which it can not be pulled.

The locking of the trigger 10 can be accomplished by the hinge rotation of the clasp 30 so that the clasp 30 further rotates toward the magazine 8 and the trigger 10 is locked more securely, An insertion groove 44 into which the support bar 32 of the latch 30 is inserted can be further formed in the inside of the insertion hole 8.

The reason for forming such an insertion groove 44 is that the rotation range of the latch 30 is determined according to the thickness of the nail pad 30. However, if the thickness of the nail pad is not less than a predetermined thickness, Since the rotation range of the catch 30 is fine and the trigger catching jaw 36 may not be caught in the hole 26 of the trigger, it is formed to prevent this.

When the lower end of the takamail is positioned above the support table 32, the latch 30 is moved toward the magazine 8 about the hinge 22 The trigger 10 is locked in the locked state while the hinge is rotated, so that the taker can easily know that the takamail has been exhausted. Accordingly, the operator can quickly mount a new Takamashi cartridge in the magazine 8, thereby shortening the working time.

In addition, since the trigger 10 can not be operated when the takamup is exhausted, unnecessary scratches on the work surface can be prevented from occurring, and the work surface can be kept clean.

Since the worker can confirm the exhaustion of the takamoo 100 according to the lock of the trigger 10 without directly checking the worker's eyes, it is possible to increase work concentration of the worker, thereby shortening the working time and preventing the accident .

In order to use the tacker of the present invention as described above, first, the cover 16 of the magazine 8 is opened and the tackifier 100 manufactured in the form of a cartridge is mounted inside the magazine 8, and the cover 16 is closed.

The support tab 32 formed on the catch 30 is then supported on the upper tab nail 100 so that the trigger catch 36 is fully inserted into the hole 26 of the trigger 10, 10 become operable (see Figs. 4 and 7A)

When the trigger 10 is pulled in a state in which the safety lever 14 is pulled in a state in which the tip end portion of the guide portion 6 is closely attached to the air port 12 by connecting the compressed air supply hose and fixing the takamail, And flows into the main body 2 to advance the piston.

With this operation, the topmost nail 100 mounted on the magazine 8 is emitted to the outside along the guide portion 6 and inserted and fixed to the object.

When one takam nail 100 is fired, the takamup cartridge is elastically moved upward by the elastic force of the elastic member, and the next takam nail is positioned on the guide portion 6. This process is performed by the magazine 8, Is repeated until the takamh (100) mounted on the main body 100 is exhausted.

When the takamail 100 mounted on the magazine 8 is exhausted to a certain extent and the takamail on the lowermost end rises to the upper side of the support table 32 by working in this manner, The support base 32 is brought into contact with the inner surface of the magazine 8 having no takam nails while being hinged to the magazine 8 about the hinge portion 22. [

The trigger jaw 36 is also slightly rotated through the hole 26 of the trigger 10 so that the trigger jaw 36 is rotated toward the hole 26 of the trigger 10 So that the trigger 10 is held in a state in which it can not be pulled out (refer to Figs. 6 and 7B)

As a result, the operator can quickly recognize the exhaustion state of the takamupo, and the new takamup cartridge can be continuously mounted on the magazine 8 as described above.

While the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
