Abstract

(57) [Technical problem] [Technical problem] Provided is a tile that has a high pull-out resistance, does not cause backlash over time, and is easy to manufacture and assemble. A split rod (2) protruding from a lower end of a billboard (1) is provided with two split grooves (3, 3 ') from the front end side, and the longitudinal dimension of a tenon hole (12) on the base (4) is adjusted to the length of the insert rod (2). Set slightly smaller than the width.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a plaque for writing a sword, and more particularly to a plaque with an improved fitting strength.

[0002]

[Prior art]

 The structure of the plaque is composed mainly of a cardboard for writing or engraving the commandments, and a platform consisting of vetch, nichinoka, flower, eggplant, return flower, tray and frame. Then, the billboard and the table side are integrally assembled by fitting a stick protruding from the lower end of the billboard to the mortise hole provided in each of the tables so as not to fall out.

[0003] As described above, in order to assemble the billboard and the table side in a mating relationship and not to use nails or the like, it is necessary to pull out the billboard from the table side and write this by holding it in hand when writing a kaname. This is to make it easier to have a letter or to engrave.

[0004]

[Problems to be solved by the invention]

 However, the above conventional tile has the following problems. a. Since the tiles are usually made of wood, their sticks shrink over time, causing so-called rattling. When the billboard is lifted to move the tiles, the stick on the billboard is moved from the table side. Each part may fall apart and fall apart. b. In order to improve the fit between the billboard and the base, dimensional accuracy is required when machining the insertion rod and the mortise. Therefore, it takes time to manufacture and assemble.

C. In order to solve the above-mentioned problem, there is a proposal of a pallet in which a single groove is formed in the insertion rod from the tip side (Japanese Utility Model No. 2-1111). However, in the case of this tile, since there is only one groove, the deformation resistance at the time of fitting is large, and the difference between the width of the insertion rod (length in the longitudinal direction) and the mortise on the side of the table cannot be made large. There is a problem. As a result, there is a disadvantage that the pull-out resistance after fitting and assembling is reduced. On the other hand, if the dimensional difference is increased in order to increase the pull-out resistance, the fitting becomes difficult, and if the fitting is forcibly performed, there is a concern that the fitting may be damaged.

[0006] The present invention is proposed in view of the above point, and an object of the present invention is to provide a tile that has a high pull-out resistance, does not rattle over time, and is easy to manufacture and assemble.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, in the invention according to claim 1, in the tablet, a plurality of split grooves are inserted from the tip end into a stick protruding from the lower end of the billboard, and a longitudinal direction of the mortise on the base is set. Is set slightly smaller than the width of the insertion rod.

[0008]

[Action]

 The billboard and the platform side are manufactured separately, and assembled by later fitting. During this assembly, the stick on the billboard is slightly larger than the mortise on the base, so it cannot be fitted as it is, so use the split groove to narrow the stick on the billboard and insert it into the mortise. When released, the stick expands elastically and fits securely in the mortise.

[0009]

【Example】

 FIG. 1 is an exploded perspective view of a tablet according to the present invention, 1 is a billboard, 2 is a stick protruding downward from the lower end of the billboard 1, and 3, 3 ′ are attached to the stick 2. This is a split groove inserted from the tip side. Reference numeral 4 denotes a stand, which is composed of a vetch 5, a second plate 6, an upper flower 7, an eggplant seat 8, a return flower 9, a receiver 10, and a frame 11, and each of which is fitted with the insertion rod 2 of the tag plate 1. A hole 12 is provided. The length of the mortise hole 12 in the longitudinal direction is smaller than the width of the insertion rod 2. The table 4 side of the embodiment is separated from the vetch 5, the second plate 6, the upper flower 7, the eggplant seat 8, the return flower 9, the receiver 10, and the frame 11, respectively. It may be.

[0010] The above-mentioned tile cannot be inserted without inserting the stick 2 of the billboard 1 into the mortise hole 12 of the base 4, so that the split grooves 3 and 3 'of the stick 2 are narrowed. And then insert it into the mortise hole 12. When the user pulls out the billboard 1 as it is, the insertion rod 2 of the billboard 1 easily comes out of the tenon hole 12 of the base 4 because of the simple fitting relationship.

[0011]

[Effect of the invention]

 As described above, the tile according to the present invention has the following effects by inserting a plurality of split grooves into the stick of the billboard. a. The size of the stick of the tile is made slightly larger than the mortise on the side of the table, and the fitting groove is narrowed at the time of fitting, so that the fitting of both is easy, and once fitted, the elastic action of the stick It is hard to come off and there is no backlash over time. b. Since the dimensional problem is absorbed by the split groove, the processing accuracy of the insertion rod and the mortise may be a little rough and easy to manufacture. c. The billboard and the base side are assembled as a single body by the elastic action of the groove, so just pull out the billboard when disassembling, and narrow the groove of the insertion rod when assembling. It is very convenient to disassemble and assemble when writing the command name because it only needs to be pushed in. d. Since less dimensional accuracy is required, production efficiency is improved and manufacturing costs are lower. e. By inserting two or more split grooves in the insertion rod, it is easy to fit, and once fitted, it is difficult to come off because of its large elastic width.
