Pen having function of a tumbling doll}

The present invention relates to a pen having a bulge, and in particular, it is possible to prevent falling and loss from a table by always maintaining an upright fixed state, and to wrap a portion in contact with a finger with an elastic body (buffer member), which is a finger according to the long-term use of writing instruments. It relates to a recessed pen that can prevent deformation and hardening of certain areas of the body.

Generally, tables and writing instruments are provided in banks and public offices for the convenience of customers and civil servants in filling out various documents. By the way, most of the writing instruments provided on such a table are general office writing instruments (ballpoint pens, signature pens, etc.), which are in the form of rods, so that they are usually laid on the table or placed in a specific device after use. It is. However, in the process of using such a common writing instrument by many people, the writing instrument often rolls off the table and rolls over the table or is lost due to careless use. Accordingly, by hanging the string at one end of the writing instrument and fixing the string to the surrounding fixture, the writing instrument is prevented from being rolled off or lost from the table, but in such a case, the writing hanging may interfere with the writing operation. There is a problem.

On the other hand, the use of general office writing instruments for a long time, some people deform certain areas of the finger or appear firm callus phenomenon. This is caused by the hard, angled parts of the writing instrument being repeatedly pressurized on a specific part of the finger for a long time.

The present invention has been made in view of the above-described matters, and an object thereof is to provide a stud pen which can prevent falling and loss from a table by always maintaining an upright fixed state even if it is left unused after use.

In order to achieve the above object, the pen according to the present invention,

A through hole of a predetermined diameter is formed in the inside of the body along the central axis, the one side end of the through hole is provided with a weight body for the function of the stub, the gripping contraction when released, and the return to the original when the release; And

The pen tip is inserted into and fixed to the through hole of the gripping member, and the pen nib which emerges into and out of the through hole of the gripping member is configured to include a pen member provided at one end of the body.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show the structure of the stud pen according to the present invention, Figure 1 is an exploded view, Figure 2 is an assembled view.

1 and 2, the pen according to the present invention is largely composed of a holding member 110 and a pen member 120.

The gripping member 110 has a generally ball-shaped shape as a whole, and a through hole 111h having a predetermined diameter is formed in the body 111 along a central axis, and at one end of the through hole 111h. A weight body 112 is provided for the top function. The body 111 of such a holding member 110 is contracted in a corresponding shape according to the degree of the pressing force of the grasped finger when the user grips (hand grasped), and when released (release the grasped) It is composed of an elastic body (buffer member) that is returned to its original state in a contracted state. In this case, a sponge or polyurethane may be used as the material of the elastic body (buffer member).

The pen member 120 is inserted into and fixed in the through hole 111h of the body 111 of the gripping member, and coupled to the cylindrical main body portion 121 and the upper end of the main body portion 121 so as to rotate left and right. The rotating manipulation unit 122 and the pen nib 123 which emerges in and out of the through hole 111h of the body 111 of the gripping member by the left and right rotation manipulation of the rotating manipulation unit 122.

Here, the main body portion 121 is an outer tube 121a having a predetermined diameter, an inner tube 121b installed to be slidably rotatable inside the outer tube 121a, and a linear and rotary motion inside the inner tube 121b. It consists of a nib moving member 125 is installed. A screw groove 121h is formed in the inner circumferential surface of the outer surface 121b, and a crank-shaped long hole 121k is formed in the inner tube 121a along the longitudinal direction of the body, as shown in FIG. 3. In addition, the pen tip moving member 125 is continuously inserted into the screw groove 121h formed on the inner circumferential surface of the outer surface 121a and the long hole 121k formed on the inner tube 121b, thereby screwing the screw groove 121h and the long hole. The protrusion 125t moving along the trajectory formed by 121k is formed.

The rotary manipulator 122 is coupled to the upper end of the inner tube 121b of the main body portion 121, and thus, when the rotary manipulator 122 is rotated to the left and right, the inner tube 121b may also rotate left and right at the same time. do. Here, preferably, the upper end of the rotary operation unit 122 is further provided with a ring 124 for allowing the stud of the present invention to hang the pen on another object (bag or backpack, etc.).

The nib 123 is coupled to the nib moving member 125 of the main body portion 121, so that when the nib moving member 125 is moved up and down linearly, the nib 123 also moves up and down at the same time. Done.

Then, it will be briefly described with respect to the operation and use of the pen according to the present invention having the configuration as described above.

First, as shown in Figure 4, in the state in which the tip of the pen tip 123 of the present invention protrudes out of the body 111 of the gripping member, when the user rotates the rotary operation unit 122 to the left, As shown in FIG. 5, the nib 123 is immersed into the body 111 of the gripping member. Then, when the rotary manipulator 122 is turned to the right in the state where the nib 123 is immersed as described above, the nib 123 protrudes to the outside of the body 111 of the gripping member as shown in FIG. 4. Done. The appearance of the pen nib 123 will be described in more detail with reference to FIGS. 2 and 3.

As shown in FIG. 2, when the user rotates the rotary manipulator 122 to the left in the state where the pen tip 123 protrudes, the inner tube 121b coupled to the rotary manipulator 122 is also simultaneously rotated left. Then, the projection 125t of the nib moving member 125 inserted into the long hole 121k of the inner tube 121b receives a rotational force from the side wall of the long hole 121k and receives a rotational drive source from the nib moving member 125. Is generated. However, as described above, the protrusion 125t has a structure in which the protrusion 125t is commonly inserted into the long hole 121k of the inner tube 121b and the screw groove 121h of the exterior 121a, so that the projection 125t rotates. The projection 125t is once moved by the screw groove 121h of the exterior 121a by the driving source, and at the same time, it is restricted by the movement trajectory by the long hole 121k of the inner tube 121b and eventually rides the long hole 121k. Will also move. That is, the projection 125t is to move on the screw groove 121h of the exterior and the long hole 121k of the inner tube at the same time. Accordingly, the protrusion 125t simultaneously performs the rotational motion by the screw groove 121h and the linear motion by the long hole 121k, whereby the nib moving member 125 and the nib 123 coupled thereto are also simultaneously. Rotational movement and linear movement will be performed. Accordingly, as a result, the pen nib 123 floats in and out of the body 111 of the gripping member by the left and right rotation operation of the rotary operation unit 122.

On the other hand, Figure 6 shows a state in which the top holding the pen in the hand according to the present invention, the user's fingers grasp the holding member 110 as shown. Therefore, the hard part of the writing instrument does not come into direct contact with a predetermined portion of the finger as in the case of using a conventional writing instrument in the hand, and as a result, the finger does not feel any pressure caused by the writing instrument. This in turn prevents the deformation of certain areas of the finger or the incorporation of calluses according to the use of conventional writing instruments.

As described above, after using the pentagonal pen of the present invention, when the ridge is released from the pen, the holding member 110 of the pentagonal pen is returned to its original form (ball shape) because it is an elastic body (for example, a sponge), and the rotary operation unit Weight body provided at the inner lower end of the body 111 even if the pen is placed on the table in a state in which the pen tip 123 is immersed into the body 111 of the gripping member 110 by rotating the 122 to the left. As shown in FIG. 5, the standing pen is finally fixed in an upright state as shown in FIG. 5. Therefore, the situation of falling off or losing from the table as in the conventional general writing instruments does not occur.

As described above, since the top pen according to the present invention has a top function by the weight provided on the lower end of the gripping member, even if it is left unchanged after use, it always maintains the upright fixed state. It can prevent the loss. In addition, since the holding member is made of an elastic body (buffer member), it is easy to grasp the hand and wraps the area where the writing instrument is in contact with the finger, thereby preventing deformation or hardening of a specific part of the finger caused by long use of the writing instrument. There is an advantage that can be prevented. In addition, the overall shape looks good and can be used as an accessory by hanging on a bag or a backpack.
