The rotation of the rotary holder tube is made convertible into the linear movement of the holder and thereby the seal provided at the fore end of the holder is made capable of opening the cap against a pressing force of the cap, or the tip of a ballpoint pen refill provided in the core holder is made capable of being projected and retracted from a metal cap. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a pay-out type seal device and a ball-point pen device in which a shaft portion to be gripped is expanded and contracted by a screw type, and a seal stamp or a nib can be moved in and out by the expansion and contraction operation.

As a conventional seal stamping device, hold the shaft part with both hands and remove the cap for stamping, or in the case of a writing instrument with a seal stamp, an operating part that slides up and down is provided on the clip. There are things that open and close the cap.

However, the former has the inconvenience of using both hands to open and close the cap, and the latter has a complicated structure and high cost.

  In addition, in the ballpoint pen device, there are telescopic ballpoint pens that allow the tip of the core to protrude and retract from the base while expanding and contracting the shaft part. The number of parts such as push rods and coil springs, the number of processing, and the assembly process increase, and there is a possibility that the structure becomes complicated and expensive.

  Accordingly, the present invention provides a seal device having excellent durability as a simple structure with a small number of parts, by extending and retracting the shaft portion with both hands (can be done with one hand) to feed out the tip of a seal or ballpoint pen. A ballpoint pen device is to be provided.

    First, as a seal device, an outer shaft cylinder provided with a cap that is always closed by a spring at the tip, an inner shaft cylinder that is linearly slidable rearward from an intermediate portion of the outer shaft cylinder, and the inner shaft cylinder Rotating shaft cylinder that is rotatable inside the outer shaft cylinder and at a fixed position inside the outer shaft cylinder, and can be slid linearly forward from the middle portion of the outer shaft cylinder, and the shaft section is positioned inside the rotating shaft cylinder so that the seal can be attached and detached. And a slider that can be locked to the rear end of the holder and fixed to the crown provided behind the inner shaft cylinder. A threaded groove is provided, and the threaded projection of the inner shaft cylinder is fitted so that the rotating shaft cylinder can be rotated by the expansion and contraction operation of the inner shaft cylinder to the outer shaft cylinder. Is provided, and the feeding protrusion provided at the inner tip of the rotating shaft tube is fitted, and the rotating shaft tube As lifting converting rotation to linear movement of the holder, a telescopic seal apparatus freely lid opening against a seal provided on the holder front end to the pressing force of the cap.

  In the ballpoint pen device, the outer shaft cylinder is provided with a detachable base at the tip, the holder is free to insert a ballpoint pen refill as a core holder, and the slider is positioned inside the rotating shaft cylinder. .

  As an effect of the present invention, the seal stamp can be fed out by an expansion / contraction operation of the seal body or the shaft of the ballpoint pen, and can be provided inexpensively with a simple structure and can be quickly assembled.

    First, regarding the seal device, the outer shaft cylinder 2 provided with the cap 1 that always closes the opening 12 at the front end via the pin 10 and the spring 11, and linearly behind the intermediate portion of the outer shaft cylinder 2. There is a slidable inner shaft cylinder 6, and an axial guide groove 14 is provided inside the rear portion of the outer shaft cylinder 1, and a guide provided on the guide groove 14 outside the proximal end portion of the inner shaft cylinder 6. The protrusion 15 is fitted, and the inner cylinder 6 moves linearly back and forth.

    Further, a rotating shaft cylinder 4 is provided which is rotatable at a fixed position inside the inner shaft cylinder 6 and inside the outer shaft cylinder 2, but the base end of the rotating shaft cylinder 4 is outside via a retaining ring 5. The shaft cylinder 2 is rotatably mounted inside.

    Next, a holder 3 is provided in which the shaft 3 ′ is slidably linearly forward from the middle portion of the outer shaft cylinder 2, and the seal 9 is detachable. A protrusion 16 provided on the outer side of the outer shaft 2 and an axial groove 17 provided on the inner side of the outer shaft cylinder 2 are fitted so as to be able to run, so that the holder 3 is linearly moved back and forth.

    Next, it fixes to the crown 8 provided in the back of the inner shaft cylinder 6 and slides inside the shaft portion 3 ′ of the holder 3, and the locking protrusions 18, 18 ′ are engaged with each other at the rear end portion of the holder 3. A slider 7 that can be stopped is provided.

    A screw groove 19 is provided on the surface of the rotating shaft cylinder 6, and the screw protrusion 20 of the inner shaft cylinder 6 is fitted and the screw protrusion 20 is threaded by the expansion / contraction operation of the inner shaft cylinder 6 to the outer shaft cylinder 2. The guide projection 15 moves along the guide groove 14 at the same time, and the rotary shaft cylinder 4 rotates.

  On the other hand, the surface of the shaft portion 3 ′ of the holder 3 is provided with a feed screw groove 21 in a direction opposite to the screw groove 19, and a feed protrusion 22 provided at the inner end of the rotary shaft cylinder 4 is fitted. The feeding protrusion 22 is moved by the rotation of the rotating shaft cylinder 4.

    In the figure, reference numeral 13 denotes an intrusion groove provided continuously at the ends of the screw grooves 19 and 21 for the corresponding protrusions 20 and 22 to enter during assembly, and also provided in the shaft portion 3 ′ of the holder 3. Further, a flat lock groove 21 ′ is provided at the end position of the feeding screw groove 21 to make the sliding with the feeding projection 22 worse and to prevent inadvertent contraction. The mechanism of the intrusion groove 13 and the lock groove 21 'can also be implemented in a ballpoint pen device described later.

Action

    The present invention is configured as described above. In order to change from the contracted state of FIG. 1 to the extended state of FIG. 2, the screw projection 20 is threaded into the screw groove 19 by pulling backward with the crown 8 or the inner shaft cylinder 6. At the same time, the rotating shaft cylinder 4 rotates, the feeding protrusion 22 moves through the feeding screw groove 21 to feed the holder 3 forward, and the cap 1 is opened against the pressing force of the spring 11 to perform the printing operation. At this time, the holder 3 stops rotating by the protrusion 16 and the guide groove 17 and moves linearly, so that the front and rear positions of the seal 9 are not always changed, and an accurate stamping operation can be performed.

  In order to change from the extended state of FIG. 2 to the reduced state of FIG.

    In combination, each part can be quickly inserted and bonded.

    In the embodiment of the ballpoint pen device of FIGS. 9 to 11, the outer shaft cylinder 2 of the seal device has a ballpoint pen size (the whole has been changed to the ballpoint pen size). The cap 1 and the like are removed, and a detachable base 30 is provided at the tip of the outer cylinder 2, and a ballpoint pen refill 31 can be inserted as the core holder 3 in the holder 3 in the seal device. The slider 7 is located inside the rotary shaft cylinder 4. In the figure, reference numeral 32 denotes a retaining ring provided with a small hole 33 communicating with the ballpoint pen refill 31, which is hooked to the tip of the slider 7.

    In order to use this ball-point pen device, first, in order to change from the contracted state of FIG. 9 to the extended state of FIG. 10, the screw projection 20 moves the screw groove 19 by pulling backward with the crown 8 or the inner shaft cylinder 6. At the same time, the rotating shaft cylinder 4 is rotated, and the feeding protrusion 22 moves in the feeding screw groove 21 to feed the holder 3 forward. The tip of the ballpoint pen refill 31 is exposed from the tip of the base 30 to be in a writing state.
