[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a stylus, and more particularly to a stylus for a personal digital assistant (PDA), hereinafter a "PDA" for a "personal digital assistant".

[0002]

[Prior art]

 For example, as shown in FIG. 1, the main features of the personal digital assistant device 100 are its elaborate structure, a keyboard such as a notebook computer is omitted, and a touch-controlled display screen 101 is used to input data or to input data in a window. A selection is made. It is difficult for the small touch control type display curtain 101 to make a touch selection with a finger, and a conventional stylus is usually provided in a PDA, and a user makes a control selection using the stylus.

[0003]

[Problems to be solved by the invention]

 However, when a large pressure is applied to the conventional display screen or the touch control display screen 101, the display screen electronic device is easily damaged, and a scar due to black pressure loss remains on the display screen. In addition, the conventional stylus method uses a pen shaft to apply pressure, and the moment effect of the pen shaft generates a larger downward pressure at the tip. There is a risk of damaging the control-type display screen 101. In particular, as shown in FIG. 1, since the tip is in point contact with the contact control-type display screen 101, the risk of damage due to the pressure is further increased. Also, since the user holds the stylus diagonally, contact selection does not always conform to arm movement custom. For the above reasons, it is an object of the present invention to provide a stylus in which the pressing force of the hand is reduced and the user can freely adjust the use angle of the stylus for the PDA or related contact electronic products.

[0004]

In order to solve the above problems, a stylus according to the present invention includes a pen shaft, a screw head, a friction sheet, a tip, a tip sleeve, and a crimping needle. The head is fixed to the end of the pen shaft, the tip with the ball head at the end and the friction sheet are sequentially inserted into the tip sleeve, and the writing needle is inserted upside down into the rear end of the tip sleeve, and the tip is further inserted. It has a structure in which the sleeve is screwed into the screw head of the pen shaft. As a result, the friction sheet can press the ball head at the tip, and the tip protruding from the tip jacket can be bent and rotated at an arbitrary angle because a constant pressure is applied. When applied to a touch-controlled display curtain of a curtain or related electronic products, it alleviates excessive contact pressure of the user, protects the contact-controlled display curtain of the PDA or related electronic products, and complies with the user's operating custom. Therefore, it is possible to input data or select contact by adjusting the angle of the tip, and the crimping needle can be used to press the built-in button on the rear side of the PDA. This allows the user to quickly control the PDA or the associated touch-controlled display electronics at any angle.

[0005] Furthermore, a pen core of a ball-point pen is provided in the pen shaft, and the tip of the pen core protrudes from one end of a tip sleeve screwed into the pen shaft. The tip of the pen head is fixed, and a telescopic cap is attached to the outer periphery of the pen head. In other words, one end of the PDA stylus where the crimping needle is not installed has the function of a ballpoint pen, and if the telescopic cap is pulled out, the brush lead Can be used as a structure to protect the tip of the pen tip of a ballpoint pen.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, the main structure of the stylus according to one embodiment of the present invention is composed of a pen shaft 1, a screw head 2, a friction sheet 3, a tip portion 4, a tip sleeve 5, and a pressure needle 6. . The pen shaft 1 is a hollow circular tube. The screw-in head 2 is a solid cylinder, a rear end of which is provided with a convex column 21 having a diameter corresponding to the inner hole of the pen shaft 1, a screw 22 is provided at a front end of the screw-in head 2, and a screw 22 is provided. A concave hole 23 is provided at the center of the hole. The friction sheet 3 is a cylindrical sheet made of a material such as rubber, plastic, Teflon, or the like. The front end portion 4 is a column made of a rigid substance (for example, plastic or metal with low bending deformation) having a conical top, and a circular ball head 41 is provided at the rear end. The front sleeve 5 is a hollow cylindrical body, and a convex edge 51 is provided on the outer periphery of the rear end, and an inner screw hole 52 is provided on the inner wall of the rear end. The crimping needle 6 has a base 61, and a front needle 62 is formed at the rear end of the base 61.

As shown in FIG. 2 and FIG. 3, the convex column 21 of the screwing head 2 is inserted into a hole at the corresponding end of the pen shaft 1 so that the screwing head 2 and the pen shaft 1 are tightly connected to each other. The rubbing sheet 3 and the crimping needle 6 are sequentially assembled into the tip sleeve 5, the front end of the tip part 4 penetrates from just one end of the tip sleeve, and the leading needle 67 of the crimping needle 6 also has the tip 4 of the leading sleeve 5. It protrudes from the other end that does not protrude. The ball head 41 is fitted into the inside of the tip sleeve 5 and the tip 4 is formed so as to be able to rotate or swing at an arbitrary angle, and the base 61 presses the friction sheet 3 and the circular ball head 41. A constant pressure is applied to the front end 4 so that it can be bent or rotated at an arbitrary angle. Thereby, as shown in FIG. 4, the tip sleeve 5 is further screwed into the front end of the screw head 2 at the rear end, and the members such as the tip part 4 are integrated into one end of the pen shaft 1 so that a certain pressure is not applied. A stylus for a PDA or related electronic product in which the tip 4 of the present embodiment can be changed to an arbitrary angle is formed so as to have a structure in which the tip 4 is bent and the angle of the tip 4 cannot be adjusted.

In the stylus of one embodiment of the present invention, a design is adopted in which the tip 4 bends at a constant pressure, and the user grips the pen shaft 1 and uses the tip 4 to use a conventional PDA or conventional PDA. When selecting an operation on an electronic product having a contact control display curtain, if the force is too large, the tip 4 bends to relieve the user of excessive writing pressure or contact selection pressure, and a PDA contact control display curtain. This prevents pressure loss due to the pointed tip 4 of the needle and effectively protects the PDA or related electronic products. In addition, since the angle of the tip 4 can be arbitrarily changed, when the user uses the PDA in a standing or sitting position, the tip 4 may be adjusted to the most customary angle in advance in use. It is possible to obtain an effect of contacting and selecting a PDA that meets personal usage customs. At the same time, as shown in FIG. 5, the structure in which the crimping needle 6 is inserted upside down at one end where the tip end portion 4 of the tip sleeve 5 is not attached allows the user to use the built-in push button on the rear side of the PDA, When pressing a built-in push button that is buried in a general hole to prevent any contact, the tip sleeve 5 can be removed and pressed with the crimping needle 6, and the PDA is conveniently used as a tool. The effect is achieved.

However, the structural design that can change the angle of the tip 4 is one of the features of this embodiment. Of course, in order to provide the user with more convenience, the other end of the stylus is used for other functions. Additional may be performed. As shown in FIGS. 2 and 6, the stylus according to the present embodiment has a structure of a ballpoint pen at one end of the PDA stylus where the tip is not provided. 7, a fitting ring 8 and a telescopic cap 9.

[0010] Since the writing lead 10 of the ball-point pen is used for ordinary writing, it may be replaced with a steel ball-point pen, a pencil or a colored pencil. The head 7 is a hollow cylindrical body, an outer thread 71 is provided at one end, and concave ring grooves 72, 73 are provided on the outer periphery of the intermediate portion and the other end where the outer screw 71 is formed, and The groove edge of the concave ring groove 73 is provided with one or a plurality of notched grooves 731 extending in the direction of the external thread 71. The fitting ring 8 is a metal ring of a hollow circular tube, and one or a plurality of pieces 81 extending toward the ring edge and into the ring are pressed on the pipe wall. One or a plurality of contact pieces 82 are provided extending in the opposite direction and obliquely inward.

The telescopic cap 9 has a hollow cylindrical shape, and has a conical head 91 having a slightly smaller diameter at one end, and a concave ring 92 provided on the outer periphery of the telescopic cap 9 to form a friction ring 93. Provided for mounting. Thus, as shown in FIGS. 2 and 6, the pen lead 10 of the ballpoint pen is inserted from one end of the pen shaft 1 where the tip sleeve 5 is not screwed, and the head 7 is inserted without the tip sleeve 5 of the pen shaft 1 screwed. Screwed to the end, the head 7 just covers the ball-point pen lead 10 so that it does not escape. The fitting ring 8 is attached between the two concave ring grooves 72 and 73 of the head 7, and a contact piece 81 extending obliquely to the rear side thereof is inserted into the concave ring groove 72. If the telescopic cap 9 is attached to the head 7 and the engagement ring 8 is inserted into the inner hole of the telescopic cap 9 as described above, the telescopic cap 9 is only moved by telescopic movement and does not come off. With such a design, the PDA stylus according to this embodiment not only has a normal writing function at the same time, but also draws out the extendable cap 9 as shown in FIG. The tip 81 that covers the tip of the core 10 and extends obliquely in the opposite direction to the above-mentioned tip 82 hits the wall edge of the front concave ring groove 73, and the tip 81 that extends diagonally to the ring edge is the front. The elastic cap 9 is inserted into the recessed groove 731 of the concave ring groove 73 to prevent the telescopic cap 9 from arbitrarily shrinking and returning or falling off, thereby protecting the tip of the brush lead 10. When the brush core 10 is used, by turning the telescopic cap 9 to separate the contact piece 82 from the notch 731, the telescopic cap 9 is moved to the head along the guide of the diagonal groove wall of the concave ring groove 73. It can be used by pushing it in and exposing the brush core 10.

Further, as shown in FIGS. 2, 3 and 6, the stylus according to an embodiment of the present invention may be provided with a well-known conical hollow push-fit type cap 20, which is provided with a distal end cap 5. To protect the tip 4 by attaching it to the tip, or to use the tip 4, the push-fit type cap 20 is moved to the end of the outer telescopic cap 9 to protect the pen tip 10 of the ballpoint pen. In other words, unless one end of the stylus is used, it is protected by its push-fit cap 20. However, the main technical expression of the present invention is a design in which the above-mentioned tip 4 can change the angle arbitrarily, and all the above-mentioned embodiments can be added depending on the situation, and therefore, a simple application of the main technology of the present invention is made. All changes and replacements shall be included within the scope of the claims of the present invention.
