Description

  The present invention relates to a fixing structure for a raised rectangular tube formed of paperboard, cardboard, PET material, PP material or the like.

  A picture book that pops out is known as a thing to raise. Utility Model Registration No. 3055010 describes that as a three-dimensional card, the three-dimensional card is folded and stored with two diagonal corners sandwiched between two corner cuts of the mount.

Utility Model Registration No. 3055010

  However, the above publication is limited to holding and storing a three-dimensional card in a mount, and there is a problem that the structure for fixing the three-dimensional card in an open state is lacking.

  The present invention solves the above-mentioned problems by providing a lock mechanism on the upright square tube body, and when it is raised up on the square tube body, the lock mechanism works to fix the square tube body in the upright state. .

  The present invention produces an effect of firmly fixing the raised rectangular tube in a state where it is raised by the lock mechanism.

  When the insertion part of the inclined piece comes out of the slit, the locking mechanism bends upward by the mount, and the push piece on the slit pushes down the tongue piece provided in the insertion part, and its end face is set to the lower end face of the slit. By abutting, an effect is obtained that a return is not generated at the end of the three ends.

  The upright rectangular tube body is firmly fixed by the lock mechanism, thereby producing an effect that it can be used as a post such as a signboard or other supporting material.

  By making the rectangular tube body flatly folded, the storage and transportation can be efficiently performed.

  The inclined piece in the rectangular tube body acts as a brace and raises the vertical tube body to produce an effect.

  The mount can be used as a signboard surface.

The top view (b) which shows the square cylinder body formation frame of 3rd Example by the expansion | deployment form before an assembly | attachment is the same expanded sectional side view of the principal part in the state where it stood up and stopped

  In the present invention, the insertion part of the tip of the inclined piece in the rectangular tube is a slit in the lower corner in the process of raising the rectangular tube forming frame with a mount formed in a folded state using paperboard into a rectangular tube shape Includes the pressing piece by pushing out the tongue piece of the insertion part with the pressing piece provided on the upper surface of the slit and pushing down the tongue piece of the insertion part while pushing the tongue piece downward and bending upward with the mount. It is configured so that the rectangular tube body is fixed in a state where it is hooked without being returned and unraveled by the three abutments.

  FIG. 1 to FIG. 5 show a first embodiment of the present invention, in which an inclined piece 1c is provided from the upper right corner 1a to the lower left corner 1b in the rectangular tube forming frame 1 which is flatly folded. An insertion portion 1 e that is extracted from the slit 1 d on the lower corner 1 b is extended and formed at the front portion of 1 c, and this rectangular tube forming frame 1 is mounted on the mount 2.

As shown in FIGS. 2 and 3, when this rectangular tube forming frame 1 is raised counterclockwise to form the rectangular tube 1G, the insertion portion 1e at the tip of the inclined piece 1c is placed on the lower corner 1b in the process. A pressing piece that is extracted from the slit 1d, bends on the mount 2 to be inclined, moves upward and advances in a horizontal state, and the tongue piece 1f provided in the middle of the insertion portion 1e protrudes from the upper end surface of the slit 1d. 3, when the insertion portion 1 e reaches the forward end, the tip surface of the tongue piece 1 f is abutted against the lower end surface of the slit 1 d, and as a result, as shown in FIG. 3 and the lower end surface of the tongue piece 1f and the slit 1d come into contact with each other, and the rectangular tube 1G is raised and fixed.
In addition, after raising to the square cylinder 1G, the insertion part 1e may be adhere | attached on the base_sheet | mounting_paper 2, and it may prevent floating away.

  Therefore, the latching by the three-way abutment is provided such that the tongue piece 1f has its distal end faced toward the base of the insertion portion 1e and hits the lower end surface of the slit 1d when the insertion portion 1e is advanced. This is achieved by forming the pressing piece 3 in a short and flat shape on the upper end face of the slit 1d so that the tongue piece 1f presses against the slit 1d. It will be a thing.

  The raised rectangular tube 1G can be formed of paperboard, corrugated cardboard, PET material, PP material, or other lightweight material, and the rectangular tube 1G has a square tube shape that is square or rectangular in cross section. As shown in FIGS. 4 to 5, (1) as a part for popping up a signboard, (2) as a part for preventing warping of a large signboard, and (3) for signboards. As a support, (4) As a fixture or other support material, (5) Use as a support on a support body that pulls and supports three-dimensional objects such as signboards that are flattened from a flat state and expanded into a quadrangle from the inside. Will be able to. The mount 2 can also be used as a signboard surface.

  FIG. 6 shows a second embodiment of the present invention in which a rectangular tube 1G is formed without a mount, and an inclination is given to the insertion part 1e at the tip of the inclined piece 1c as shown in the development view of FIG. A ruled line (folding line) 4 is provided for unraveling and coming out horizontally, and in the process of raising the square tube forming frame 1 counterclockwise, the insertion portion 1e bends horizontally from the slit 3 and is pushed out by the push piece 3. The piece 1f is pushed down so as to abut against the lower end face of the slit 1d. Other configurations and operations are the same as those of the first embodiment.

  FIG. 7 shows a third embodiment of the present invention, in which a hook hole 5 is provided in the middle of the insertion portion 1e, and when the rectangular tube forming frame 1 is raised, the pressing piece 3 is hooked to hook the insertion portion 1e. It is intended to stop. Other configurations and operations are the same as those of the first embodiment.

  The present invention is widely used as a fixing structure when a rectangular cylinder is raised and formed with a lightweight material such as paperboard.
