Description

A stylus pen with an air flow slit}

The present invention relates to a stylus pen, and more particularly, to a stylus pen with a reduction in processing cost and a simplification of an assembly process and an enhanced structure.

In general, a portable personal digital assistant refers to all types of terminals that a person can carry, such as a personal digital assistant (hereinafter referred to as a PDA), a next generation mobile communication terminal, a handheld PC, and the like. As these portable wireless terminals are gradually spread and commercialized, wireless terminals having various functions have emerged, and the design and miniaturization of the terminals with various functions have a great influence on sales.

Accordingly, in addition to the basic functions for transmitting and receiving voices with the other party, the terminal is equipped with various functions capable of processing Internet functions, text information, graphics, and the like. In order to satisfy these two needs of adding and miniaturizing such functions, The touch screen method or voice input method that does not require the keypad is introduced.

Among them, a stylus pen is used to operate a touch screen terminal. The stylus pen is formed in the shape of a writing instrument, and a tip for inputting and outputting information is formed at an end portion. Since the stylus pen generally has to be mounted in a mounting hole separately provided in the terminal or to be carried in a pocket or the like, its volume should be small. In addition, when used for input and output of information should be large enough to be held by the user's hand.

A prior art related to such a stylus pen is disclosed in Korean Patent Utility Model Publication No. 20-0327592 (2003.09.26) "Stylus pen". The prior art includes a head having protrusions and hooks respectively formed at the front and rear ends, a tube having a locking jaw formed at the rear end while engaging the hook at the front end, and a rod integrally formed with the piston at the front end while being coupled to the tube. And a stylus pen formed by a ring coupled to the piston and closely attached to the inner surface of the tube, and a handle coupled to the rear end of the rod, wherein the rod has an air passage formed at a distal end of the piston. It relates to a stylus pen, characterized in that it comprises a bushing provided in.

In the prior art, the air distribution groove is cut in the longitudinal direction at the bottom of the piston for the distribution of air during the operation of the rod. It has a narrow and narrow shape, so the machining process is difficult, there is a problem that the manufacturing cost according to the processing cost is increased.

In addition, the conventional stylus pen has a small amount of air circulated through the air flow groove cut in the piston, so that friction occurs during the reciprocating movement of the rod, so that the sliding feeling is not smooth.

The present invention has been devised to solve the problems described above, an embodiment of the present invention relates to a stylus pen formed with an air flow rail groove which is simplified in the assembling process and strengthened as well as the processing cost is reduced.

A preferred embodiment of the present invention is a stylus pen composed of a body and a pen support portion fixed to the body and a pen portion accommodated in the body and drawn out and returned through the pen support portion, the body having an air flow rail groove long in the longitudinal direction. The stopper support portion having the stopper locking groove is formed on the lower inner wall of the pen support portion, and the stopper is formed on the lower side of the pen support portion to stop the stopper locking groove, and the stopper support portion is formed to have an incision formed therein. It provides a stylus pen formed air flow rail groove characterized in that it has.

According to one embodiment of the present invention as described above, first, it is possible to reduce the processing cost by forming an air distribution rail groove in the body.

Second, the hook fixing groove formed in the body and the hook protrusion formed in the pen support portion can simplify the assembly process and strengthen the coupling structure.

1 is an exploded perspective view illustrating a stylus pen having an air flow rail groove formed in accordance with an embodiment of the present invention, FIG. 2 is an exploded cross-sectional view of the stylus pen shown in FIG. 1, and FIG. 3 is a stylus illustrated in FIG. 1. A plan view of the body employed in the pen.

The stylus pen 1 having an air flow rail groove according to a preferred embodiment of the present invention includes a body 10, a pen support part 20, and a pen part 30.

The body 10 is a portion in which the lower side of the edge 21a of the pen support part 20 to be described later is coupled, and as shown in FIG. 1, the inside of the body 10 is preferably hollow so that the pen part 30 to be described later is movable. . On the upper side of the body 10, as shown in Fig. 1, 2, the hook fixing groove 12 is fixed to the hook projection 21b of the pen support 20 to be described later is formed, the hook fixing groove 12 In the position spaced apart from the air flow rail groove 11 extending in the longitudinal direction to the bottom of the body 10 is formed.

The air flow rail groove 11 acts as an air passage so that the compressed air escapes when the pen part 30 enters the body 10. Preferably, the air flow rail groove 11 forms a 90 ° angle as shown in FIG. Dogs are formed.

The pen support part 20 has a hollow inside so that the pen part 30 to be described later is movable, and as shown in FIG. 1, a rim 21a is formed at the center portion and a hook protrusion 21b is formed at the lower portion thereof. 2 and the stopper support part 22 which is formed spaced apart from the lower inner wall of the support body 21, and the stopper engaging groove 22a is formed in the inner wall as shown in FIG.

Although not shown in the drawing, the hook protrusions 21b are preferably four, forming the 90 ° angle as in the hook fixing groove 12 described above.

The stopper support part 22 supports the pen part 30 when the pen part 30 to be described later moves, and the stopper 30a formed in the pen part 30 is the stopper support part 22 when the pen part 30 is moved to the maximum. To be supported by the stopper locking groove (22a) of the. At this time, the stopper support portion 22 is formed with a cutout portion 22b so as to have an appropriate elasticity when the stopper 30a is caught in the stopper engaging groove 22a.

Pen portion 30 is moved through the interior of the pen support portion 20, the stopper (30a) for fixing the pen portion 30 to the pen support portion 20 is preferably as shown in Figure 1 The lower end portion has an expanded shape in diameter. A tip for inputting information is formed at an upper end of the pen part 30.

4 is an operational state diagram of the stylus pen shown in FIG.

In order to use the stylus pen 1 having the air distribution groove according to the preferred embodiment of the present invention, the end of the pen part 30 is pulled out. At this time, the pen portion 30 is drawn to the outside while being supported on the inner wall of the pen support portion 20 when withdrawing. At this time, the air introduced through the space between the pen support portion 20 and the pen portion 30 is distributed downward through the air flow rail groove 11 formed in the body 10 as shown in FIG. When the pen unit 30 is withdrawn and returned, air is smoothly distributed through the air flow rail groove 11 to impart proper damping to the inside of the body 10. As a result, not only the sliding feeling can be improved during the reciprocating motion of the pen part 30, but also a conventional process of cutting the lower side of the pen support part 20 for air distribution is unnecessary, thereby reducing the processing cost. On the other hand, by hooking the hook projection (21b) of the pen support portion 20 to the hook fixing groove 12 formed in the body 10 there is an advantage that can simplify the assembly fixing and strengthen the coupling structure.

The present invention can be variously modified by those skilled in the art without departing from the scope of the claims claimed in the utility model registration claims, the technical protection scope of the present invention is the specific preferred embodiment described above It is not limited to the example.
