[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a portable seal stamp.

[0002]

[Prior art]

 A stamp with a letter or the like engraved on the end face of a columnar member made of wood or stone is generally used. However, such seals have to be carried in a separate bag or case because clothes and belongings are contaminated by the stamped meat attached to the tip surface. For this reason, there is a risk that the seal will be lost or that only the empty case will be inadvertently carried around. In addition, storing a stamp with a wide character in a larger case made it inconvenient to bulky and carry.

Further, the ink is stored in a hollow case having characters engraved on the front end surface thereof, and a cylinder wall is provided around the front end surface of the case so that the cylinder wall can be retracted and retracted. There is a known seal stamp that can be inserted and imprinted with the tip surface to which ink is attached. However, even when this is not in use, a separate cap must be attached to prevent contamination by ink, and if it has a wide text surface, it does not have a means for downsizing so that it is convenient to carry. . In addition, due to the material of the character surface, it is often the case that such seal imprinting is not officially recognized.

[0004]

[Problems to be solved by the device]

 The purpose of the present invention is that when not in use, the seal main body can be stored in an integral outer cylinder with a smaller cross section, which makes it easy to carry and there is no risk of stains on the clothes etc. The purpose is to provide a seal that prevents the case or seal body from being lost.

[0005]

[Means for Solving the Problems]

 The seal of the present invention includes an outer cylinder whose both ends are open, a supporting base slidably fitted in the outer cylinder, and a support mounted at one end of the supporting base so as to be retractable in the outer cylinder. The stamp main body is fitted with the main body of the seal, and the depth of the main stamp body is larger than the height in the cross-section internal method of the outer cylinder, and the operating portion protruding from the outer cylinder is provided at the other end of the support base. Side frames are projected from both sides in the direction of one end respectively, and the seal main body is rotatably attached to the tip of the side frames. A stopper that engages with the protrusion of the guide rod is provided at the intermediate portion in the sliding direction inside the outer cylinder in order to regulate the sliding of the support base to the other end, and between the stopper and the operating portion. A spring for urging the support base toward the other end is fitted around the outer circumference of the guide rod.

When the seal is not used, the support base slides to the other end side by the urging force of the spring, the seal body is housed inside the outer cylinder, and the projection of the guide rod and the stopper are engaged. , Restrict the support base from coming out of the outer cylinder. When using the seal, pressing the operation part causes the support base to slide to one end side, causing the seal main body to protrude outside the outer cylinder, allowing the seal main body to rotate without being restricted by the peripheral wall of the outer cylinder. . When the seal base is rotated to free the support base, the support base slides toward the other end due to the biasing force of the spring, but the seal main body is caught on the edge of the outer cylinder and cannot be immersed. When the operation portion is pushed again, the seal main body can be rotated away from the edge of the outer cylinder, so that the support base can be freely rotated after rotating the seal main body to the original position. Then, the support base slides to the other end side by the force of the spring, and the seal stamp main body sinks into the outer cylinder.

At this time, a reinforcing plate is installed between the side frames and is engaged with a stopper at a position matching the protrusion of the reinforcing plate in the sliding direction so as to restrict the sliding of the support base to the other end side. It is also possible to form a blocking ridge that fits together. By doing so, the strength of the support base increases, the side frame is prevented from opening, and the seal main body is prevented from coming off, and the outer cylinder and the support base can be positioned stably when the support base slides to the other end side. To be done.

Further, the seal stamp of the present invention is installed between a pair of outer cylinders whose opposite ends are open, a pair of support bases slidably fitted in the outer cylinders, and the opposite ends of the support bases. In addition, the stamper main body is fitted into the outer cylinder so as to be retractable from the opposite ends thereof, and the support base has a pair of left and right side frames and a reinforcing plate laid between the side frames. , The seal main body is attached to the ends of the left and right side frames, and the blocking ridges are formed on the reinforcing plate, and the sliding of the support base to the opposite end side is regulated at the middle part in the sliding direction inside the outer cylinder. It is also possible to provide a stopper that engages the blocking ridge.

When the seal stamp is not used, the support bases are slid toward the innermost ends of the outer cylinders to bring the pair of outer cylinders close to each other, and the seal main body is housed near the opposite ends of the outer cylinders. When using the seal, slide the outer cylinders away from each other to expose the seal body, then rotate the outer cylinder and the support to the same side so that both outer cylinders and the support are in parallel. At the same time, the seal main body is positioned at the end.

Further, the seal stamp includes a pair of outer cylinders whose opposite ends are open, and a seal stamp main body which is installed between the opposite ends of the outer cylinder and can be fitted into the outer cylinder. Cut out the opposite ends of the upper plate and the upper plates of both side plates to approximately the same depth as the depth of the stamp main body, and cut the opposite ends of the other outer cylinder into the lower plate and the lower plate side parts of both side plates. The stamp body is cut out to have substantially the same length as the depth, and the cutout portions of both outer cylinders can be engaged with the concave and convex parts. One side portion of the seal body in the depth direction is attached to the side plate of one outer cylinder and the other outer cylinder. The other side portion in the depth direction of the stamp main body is axially attached to the side plate of each of the outer cylinders, and the lower plate tip of the one outer cylinder and the upper plate tip of the other outer cylinder are detachably engaged with the back surface of the stamp main body. You may form a recessed part.

When the seal stamp is not used, both outer cylinders are aligned in a straight line and the cutout portions are engaged with each other, and the seal stamp main body is housed inside the opposite end portion of the outer cylinder. When using a seal, rotate both outer cylinders to the rear side of the seal main body and arrange them side by side, and place the lower plate tip of one outer cylinder and the upper plate tip of the other outer cylinder in the recesses of the seal main body. Mate and expose the seal body. In this seal, a concave groove and a convex portion that engage with each other when the cutout portions are engaged with each other can be formed at the edges of the cutout portions of both outer cylinders.

[Embodiment of the invention]

 1 to 7 show a first embodiment of the present invention. As shown in FIG. 1, the seal stamp of the present invention includes an outer cylinder 20 having both ends open, a support 10 slidably fitted in the outer cylinder 20, and an outer cylinder attached to one end of the support 10. The seal main body 30 is fitted into the cylinder 20 so as to be retractable. The outer cylinder 20 has a rectangular cross section, and a substantially inverted U-shaped stopper 21 having a through-hole formed in the center is provided at an inner portion of the outer cylinder 20 at a height that does not reach the lower plate from the inner surface of the upper plate. To be Further, as shown in FIG. 3, a holding piece 22 for holding a pocket opening or the like of clothes is provided on the lower surface of the lower plate of the outer cylinder 20 on the other end side.

The support base 10 is formed to be longer than the outer cylinder 20, and is provided with an operation portion 11 projecting to the outside of the outer cylinder 20 at the other end. The operating portion 11 has a rectangular cross section that is slightly smaller than the inner diameter of the outer cylinder 2, and as shown in FIG. The side frame 12 is provided so as to project along the inner surface of the side plate of the outer cylinder 20. In addition, a cylindrical shaft 1210 is provided so as to protrude from the inner surface of the front end portion of the side frame 12.

Further, as shown in FIGS. 3 and 4, a reinforcing plate 14 is installed between the lower edges of the side frames 12 so as to pass along the lower end of the stopper 21 and slide along the inner surface of the lower plate of the outer cylinder 20. Then, a blocking ridge 1410 is formed along the width direction on the upper surface of the reinforcing plate 14 at a position closer to one end than the stopper 21. A guide rod 13 is provided between the left and right side frames 12 so as to project from the operation portion 11 toward one end. As shown in FIG. 4, the guide rod 13 is inserted into the central portion of the stopper 21, and a protrusion 1310 facing upward is formed at a position corresponding to the blocking protrusion 1410 in the sliding direction of the tip end thereof.

As shown in FIGS. 2 and 3, the blocking ridges 1410 and the protrusions 1310 engage the stoppers 21 when the support base 10 slides to the other end side, so that the support bases 1010 and 1013 are engaged. The above sliding is regulated. A coil spring 15 is fitted around the outer circumference of the guide rod 13 between the operating portion 11 and the stopper 21. The coil spring 15 urges the operation portion 11 and the stopper 21 away from each other, that is, the support base 10 is located on the other end side with respect to the outer cylinder 20.

The stamp main body 30 is formed into a rectangular parallelepiped having a width substantially the same as the width in the cross-section method of the outer cylinder 20, a thickness slightly smaller than the height in the cross-section method, and a depth larger than the height in the cross-section method. Characters are engraved. Therefore, the front surface of the stamp main body 30 on which the characters are formed is wider than the cross-sectional area of the outer cylinder 20. Further, a circular hole 31 is formed at a position slightly eccentric in the side surface of the stamp main body 30 in the depth direction, and by inserting the shaft 1210 of the support base 10 into the circular hole 31, the seal main body 30 is formed on the inner surface of the side frame 12. It is rotatably mounted in between. When the stamp main body 30 is rotated so that its front surface faces upward, the back surface of the seal stamp main body 30 contacts the reinforcing plate 14, and the front surface of the seal stamp main body 30 is orthogonal to the sliding direction of the support base 10. It is advisable to set the length of the reinforcing plate 14 so as not to prevent the rotation of the reinforcing plate 14.

The seal stamp is used as follows. In the normal state, as shown in FIGS. 2 and 3, the operating portion 11 is pushed by the coil spring 15 and the support base 10 is located on the other end side of the outer cylinder 20. Then, the projection 1310 of the guide rod 13 and the blocking ridge 1410 of the reinforcing plate 14 come into contact with the stopper 21 to prevent it from coming out of the outer cylinder 20 of the support base 10. In this state, the seal main body 30 is immersed inside the outer cylinder 20, and there is no concern that the seal meat attached to the front surface of the seal main body 30 stains the surroundings, so that the seal main body 30 can be carried in a pocket of clothes or the like. At this time, the front surface of the stamp main body 30 faces upward and the back surface contacts the reinforcing plate 14.

When stamping, when the operating portion 11 is pushed toward one end, as shown in FIG. 5, the seal body 30 is exposed to the outside of the outer cylinder 2, and the coil spring 15 approaches the operating portion 11 and the stopper 21. Compressed between and. Further, since the seal stamp main body 30 is eccentrically attached to the side frame 12 and the rear surface of the seal stamp body 30 is in contact with the reinforcing plate 14 to prevent the seal stamp body 30 from rotating to one side, the front surface of the seal stamp body 30 is automatically supported. Rotate to face one end.

When the hand is released from the operation section 11 in this state, the support base 10 moves slightly to the other end side due to the restoring force of the coil spring, but the depth of the seal main body 30 is larger than the height of the outer cylinder 20 in the cross section. Since it is large, as shown in FIGS. 6 and 7, the seal main body 30 is caught in one end of the outer cylinder 20 and cannot be retracted, and is stable with the front surface facing outward. Therefore, it can be stamped in the same manner as a normal seal. When the seal main body 30 is housed inside the outer cylinder 20, when the operating portion 11 is pushed toward one end side, the back surface of the seal main body 30 can be rotated away from the edge of the outer cylinder 20 as shown in FIG. Therefore, the seal main body 30 is rotated until its rear surface comes into contact with the reinforcing plate 14, and then the operating portion 11 is released. Then, the seal main body 30 is retracted into the outer cylinder 20 as before, and the support base 10 slides to the other end side.

8 to 13 show a second embodiment of the present invention. As shown in FIG. 8, the seal includes a pair of outer cylinders 2A having opposite ends 205A opened, a pair of support bases 1A slidably fitted in the outer cylinder 2A, and opposite end portions of the support bases 1A.

A guide groove 203A is formed over the entire length in the longitudinal direction. Further, as shown in FIG. 9, stoppers 204A are provided so as to face each other in the width direction on the upper plate lower surface and the lower plate upper surface of the outer cylinder 2A, respectively. The distance from the opposite edge of the outer cylinder 2A to the stopper 204A is approximately equal to half the depth of the seal main body 3A. Further, as shown in FIG. 11, an engaging recess 206A having a shallow arc-shaped cross section is formed on the side of the upper surface of the lower plate near the facing end 205A of the outer cylinder 2A.

The support base 1A is formed slightly shorter than the outer cylinder 2A, and has a pair of left and right side frames 102A along the outer surface of the side plate 202A of the outer cylinder 2A, as shown in FIG. Further, as shown in FIG. 8, a cylindrical shaft 103A is projectingly provided on the inner surface of the front end portion of the side frame 102A so as to face it, and the support base 1A is arranged in parallel with the upper edge of the front end of the side frame 102A. An arcuate chamfered portion 106A is formed so as not to get in the way when moving. Further, as shown in FIG. 11, when the support base 1A slides toward the rear end 201A side of the outer cylinder 2A on the lower surface of the side frame 102A near the facing end portion, the engagement recess 206A of the outer cylinder 2A is formed. An engaging convex portion 105A having an arcuate cross section that is detachably engaged is formed.

A reinforcing plate 101A is installed between the central portions in the height direction of the left and right side frames 102A from the rear end to the middle portion thereof, and as shown in FIG. A blocking protrusion 104A is provided along the protrusion. Further, as shown in FIG. 10, a gap is formed between the end of the blocking ridge 104A and the inner surface of the side frame 102A so that the side plate 202A of the outer cylinder 2A can pass therethrough. As shown in FIG. 12, when the supporting base 1A slides toward the facing end 205A side of the outer cylinder 2A by a certain distance and the stamp main body 3A is completely exposed, the blocking protrusion 104A comes into contact with the stopper 204A. Further movement of the support base 1A is restricted.

Similar to the first embodiment, the stamp main body 3A has a width that is substantially the same as the width in the cross-section method of the outer cylinder 2A, a thickness slightly smaller than the height in the cross-section method, and a depth larger than the height in the cross-section method. Is formed into a rectangular parallelepiped, and letters and the like are engraved on the front surface thereof. Further, circular holes 301A are respectively formed slightly on both sides of the center of both side surfaces of the stamp main body 3A, and by inserting the shaft 103A of the support base 1A into the circular holes 301A, the seal main body 3A is moved to both support bases 1A. Is rotatably mounted between the inner surfaces of the left and right side frames 102A.

This seal is used as follows. When carrying, as shown in FIG. 9, a pair of outer cylinders 2A are arranged in series and brought close to each other, and their opposing ends 205A are brought into contact with each other. Then, the seal stamp main body 3A is housed between the stoppers 204A inside both outer cylinders 2A. At this time, since the engagement concave portion 206A of the outer cylinder 2A and the engagement convex portion 105A of the support base 1A are engaged with each other, the outer cylinder 2A does not move unintentionally.

When imprinting, as shown in FIG. 12, the outer cylinder 2A is pulled away from each other and the engagement recess 206A and the engagement projection 105A are disengaged from each other, so that the support base 1A is removed from the outer cylinder 2A. On the other hand, the seal main body 3A is completely exposed by sliding it toward the facing end 205A. Next, as shown in FIG. 13, both outer cylinders 2A are rotated to the rear side of the stamp main body 3A so as to be arranged side by side, and the front surface of the stamp main body 3A is positioned at the leading end of the stamp. In this state, the stamped meat is attached to the front surface of the stamp main body 3A, and the stamp is imprinted in the same manner as a normal stamp.
