Description

Stylus pen

The present invention relates to a stylus pen, and in particular, when the rod moves forward and backward, air is allowed to enter and exit the tube so that the rod can be operated smoothly, and also the position and fixing of the stylus pen coupled to the terminal The present invention relates to a stylus pen that is made more stable to improve convenience in use.

In general, the stylus pen is used for selecting information or inputting information on screens installed in various terminals. Due to the miniaturization of the terminal, the stylus pen is miniaturized together.

Therefore, the stylus pen as described above has been on the rise to improve the convenience to carry while losing the possibility of lost.

The prior art is described in the prior registration of the registered registration No. 20-0290278 (name: stylus pen having a multi-stage structure and a portable personal information terminal containing the same) in Figure 5, first, the terminal main body 200 is a stylus pen It is configured while coupling the inside (100), wherein the stylus pen 100 is fixed by the pen holder hook 231 formed inside the terminal body (200).

The stylus pen 100 installed as described above is formed in a cylindrical shape as shown in FIG. 6, and has a front end-shaped body 110, and an outer circumference of the front portion of the body 110 in a pen holder hook 231. Hanging grooves 111 to be caught are formed along the circumference, grooves 112a and 112b are formed along the inner circumference at the front and rear portions of the body 110, and the locking jaw 113 at the entrance of the body 110. It is bent inwardly and formed.

In addition, the body 110 is coupled to the expansion member 120 that moves forward and backward, and the protrusion 121 that is caught by the grooves 112a and 112b protrudes along the outer circumference of the front portion of the expansion member 120. It is formed.

Along with the expansion member 120, the pen-entry handle 130 is coupled.

Referring to the operation of the conventional technology configured as described above is as follows.

First, when the stylus pen 100 is pulled out of the terminal body 200 by grabbing and pulling the pen pull-out handle 130, the extension member 120 is retracted. At this time, the pen holder hook 231 is caught in the locking groove 111. Since the body 120 is in a relation that the body 120 stays in the terminal body 200, the expansion member 120 moves backward.

Therefore, the protrusion 121 slides along the inner circumferential surface of the body 110 while leaving the groove 112a and stops while being introduced into the other groove 112b. As a result, the expansion member 120 is withdrawn from the body 110. It becomes the state to become.

The body 110 is pulled out by pulling the pen in / out handle 130. As a result, the pen holder hook 231 is separated from the catching groove 111, and the body 110 is withdrawn from the terminal body 200. Are separated.

After the stylus pen 100 is separated as described above, information is inputted to or selected from the tip of the stylus pen 100 through the screen constituting the terminal body 200.

Unlike the above, when the stylus pen 100 is coupled to the terminal body 200, the pen holder hook 231 is fixed to the locking groove 111 while being positioned. However, when the stylus pen 100 is pushed further, the terminal body 200 is further pushed inside. Will enter.

Since the conventional technique has a structure in which the body 110 is hermetically sealed, air does not smoothly enter and exit the body 110 when the expansion member 120 moves forward and backward, so that the expansion member 120 There is a flaw that cannot smoothly move forward or backward.

Another problem is that the structure for fixing while limiting the coupling position of the stylus pen 100 coupled to the terminal body 200 is not formed in the terminal body 200, so that the coupling state becomes unstable.

The present invention aims to allow the rod to operate smoothly by allowing air to enter and exit the tube when the rod moves forward and backward.

Another purpose is to make the coupling position and the fixed state of the stylus pen coupled to the terminal to be more stable, to improve the convenience in use.

It consists of 42.

Hereinafter, in the technical configuration of the present invention, as shown in FIGS. 1 to 4, the stylus pen 2 constituting the present invention is detachably installed in the terminal 4, and the case 6 constituting the terminal 4 is provided. The back of the coupling groove 8 is formed, the battery is attached, detached, the upper groove 10 and the side wall 12 is positioned around the coupling groove (8), respectively.

The guide hole 14 is formed in a circular shape through one side of the upper wall 10 formed as described above, and the engaging jaw 16 defining the engagement position protrudes from the upper side of the inlet of the guide hole 14. Is formed.

And the end of the guide hole 14 is formed in the side wall 12 while the rest room 18 is extended, the locker 20 that acts as a locking on the rear side of the rest room 18 can flow up and down. It is installed to be, the end of the rest room 18 is formed integrally while the hook portion 22 to be a fixed role is bent "a".

The stylus pen 2 is mounted to the rest room 18 of the case 6 configured as described above. The structure of the stylus pen 2 will be described below.

First, the stylus pen 2 is configured while the head 26 forming the protrusions 24 to input information on the screen constituting the terminal (personal digital assistant, etc.) integrally forms the hook 28 at the rear end. The hook 28 of the head 26 is installed while the tubular tube 30 is coupled to the distal end, and the catching jaw 32 is bent inward to prevent the detachment from the rear end of the tube 30. It is formed.

The outer periphery of the tube 30 is formed with a groove 33 along the circumference to allow the locker 20 to be hung, and a hole 35 through which air can enter and exit the one side of the groove 33. It is formed through.

And the rod (36) is installed in the tube 30, the rod 36 is moved forward and backward in the shape of a rod, the front end of the rod (36) is integrally formed with a piston 38 to move along the interior of the tube (30) On the outer circumference of the piston 38, the ring 40 is coupled to be located in close contact with the inner circumferential surface of the tube 30.

Along with the rod 36, the handle 42 located at the outer end of the tube 30 is integrally formed at the rear end of the rod 36, and the locking jaw 16 formed at the guide hole 14 is formed at the rear of the handle 42. The stopper 44 caught by the protrusion protrudes.

Referring to the operation of the present invention configured as described above are as follows.

First, while pulling the top surface of the stopper 44 while pulling the stylus pen 2 out of the case 6, the tip end portion of the stopper 44 is spaced apart from the catching jaw 16, and at the same time, the handle 42 is loaded with a rod ( 36 and the piston 38 is retracted out of the guide hole 14 while moving backward.

At this time, since the groove 33 formed in the tube 30 is locked to the locker 20, the tube 30 of the stylus pen 2 stays in the rest room 18, and together with the piston ( The ring 40 installed in 38 is moved in close contact with the inner surface of the tube 30, so that the rod 36 moves backward while maintaining balance.

As described above, when the piston 38 moves backward, suction force is applied to the outside air into the tube 30 through the hole 35, which causes the piston 38 to move smoothly inside the tube 30. Will be.

Subsequently, when the rod 42 is pulled backward by pulling the handle 42, the piston 38 is stopped while being caught by the catching jaw 34, and the pull of the handle 42 is no longer performed. In the above state, when the user pulls the handle 42 with a larger force than the first, the rear end of the piston 38 is caught by the locking jaw 34 and pulled, so that the tube 30 is fixed in the rest room 18. Pulled.

Therefore, the locker 20 caught in the groove 35 of the tube 30 is pushed away from the rear, which causes the tube 30 to move freely to move backward with the rod 36. .

When the tube 30 is pulled as described above, the stylus pen 2 is fully opened and used as a writing instrument while moving along the rest room 18 and separated out of the case 6 through the guide hole 14. It becomes the size suitable for the following.

When the stylus pen 2 is completely separated from the terminal 4, the projection 24 is placed on the information displayed on the screen constituting the terminal 4, and the necessary information is selected or other data is input.

On the other hand, contrary to the above, the use of the stylus pen 2, which has been terminated, is coupled to the terminal 4, and an operation sequence thereof is as follows.

First, when the head 26 and the tube 30 pass through the guide hole 14 and reach the hanger 22 through the rest room 18, the locker 20 is pushed outward by the tube 30. After reversing, elastically return to the original position and flow into the groove 33 formed on the outer periphery of the tube 30, which causes the tube 30 to be fixed in the restroom 18.

Subsequently, when the handle 42 is pushed, the handle 42 and the rod 36 piston 38 and the like are advanced together while the tube 30 is fixed on the rest room 18.

As described above, when the piston 38 moves forward, the ring 40 coupled to the outer circumference of the piston 38 moves forward while being sealed, thereby exhausting the air in the tube 30 to the outside through the hole 35.

Therefore, when the piston 38 moves forward and backward, the air in the tube 30 enters and exits through the hole 35, so that the pressure inside the tube 30 is at the same level as the atmospheric pressure. 38) will be able to move forward and backward smoothly.

As the rod 36 continues to move forward, the stopper 44 reaches the locking jaw 16 and the movement of the handle 42 is stopped, and at the same time, the handle 42 is positioned in the guide hole 14, As a result, the stylus pen 2 is coupled to the inside of the terminal 4 while being folded as a whole.

The present invention has the effect of improving the operability of the rod because the air is going out through the hole formed in the tube when the rod is moved forward, backward.

Another effect is that the hook part and the hooking jaw are formed in the case, so that the stylus pen is stably fixed to the case, thereby improving convenience in use.
