Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper holder for holding various types of roll paper such as toilet paper and cooking paper. 2. Description of the Related Art Various paper holders for attaching various types of roll paper have been conventionally proposed. In particular, a simple and inexpensive synthetic resin paper holder capable of replacing roll paper with a single touch is widely used in practice. As such a paper holder, for example, as shown in FIG.
And a pair of side plates 2 and 2 bent forward from both sides of the back plate 1, and roll paper supporting projections 3 and 3 provided inside the side plates 2 and 2 so as to be freely retractable. It is well known that the upper side of the side plates 2 and 2 is provided with a cover pivotally supported on both sides of the base and a paper cutting cover 4 which also serves as a roll paper cutting cutter. [0004] The paper cutting cover 4 described above.
Are supporting shafts 5, 5 protruding outward on both sides of the base.
When fitting into the shaft holes 6, 6 formed in the upper inner part of the side plates 2, 2, the both side plates 2, 2 must be spread outward, and therefore, the two side plates 2, 2 In some cases, the bent portion between the base and the back plate 1 was cracked or the plating was peeled off. Further, when the rigidity of the bent portion is high, the mounting operation of the paper cutting cover 4 itself may be complicated. The present invention has been made in view of such circumstances,
An object of the present invention is to provide a paper holder to which a paper cutting cover can be attached without expanding a side plate. According to the present invention, means for solving the above-mentioned problems are constituted as follows. That is, a back plate attached to a wall surface, a pair of side plates bent forward from both sides of the back plate, and a roll paper supporting protrusion that is assembled so as to be able to protrude and retract inside the side plate; A paper holder comprising a cover pivotally supported on both sides of a base and a paper cutting cover serving also as a roll paper cutting cutter at an upper portion on the inner side of the side plate, wherein the paper cutting cover is directed outward on both sides of the base of the paper cutting cover. The shape of the cross section perpendicular to the axis of the support shaft protruding is formed in a substantially D-shape, and a retaining portion that allows only a short diameter portion of the support shaft to pass therethrough and a long diameter portion of the support shaft are fitted. A long hole having a fitting portion on both the front and rear sides of the retaining portion is formed by drilling in the upper rear inner side of one of the side plates, and only the shorter diameter portion of the support shaft is formed in the upper rear inner side of the other side plate. The retaining part to be passed and the front part formed on the front side An inverted L-shaped long hole is formed having a downward guide portion capable of loosely fitting the major axis portion of the support shaft and a fitting portion formed behind the retaining portion and capable of fitting the major diameter portion of the support shaft. It is characterized by being done. After inserting one support shaft of the paper cutting cover into the front fitting portion of the long hole of one of the side plates, the other of the paper cutting cover is inclined downward to connect the other support shaft. After fitting into the lower end of the guide portion of the other side plate and moving it upward, the short diameter portions of the two support shafts are passed through the retaining portions of both long holes and pushed into the rear fitting portions, thereby assembling. Ends. In the assembled state, since the two support shafts are prevented from moving by the retaining portions, the paper cutting cover is swingably supported while being fitted in the rear fitting portion. An embodiment of the paper holder of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a view corresponding to assembling a one-touch paper holder made of a synthetic resin material. In the drawing, reference numeral 1 denotes a back plate attached to a wall surface, 1a,
... are bolt holes, 2 is a side plate bent forward from both sides of the back plate 1, 3 is a projection for supporting roll paper, which is assembled inside the side plate 2 so as to be freely retractable, and 4 is a cover. A paper cutting cover that also serves as a roll paper cutting cutter. Both sides of the base are pivotally supported by the upper inner side of the side plates 2 and 2 and can be turned upward. On both sides of the base of the above-described paper cutting cover 4, support shafts 5 and 5 are protruded outward, and the support shafts 5 and 5 have a cross section perpendicular to the shaft by a so-called D-cut. It is formed in a substantially D-shape. In addition, the D-cut portion is indicated by reference numeral D. [0011] In the upper part on the inner side of the inner side of the side plate 2, the major axis of the support shaft 5 is provided on both front and rear sides of a narrow retaining portion 61 through which only the short diameter portion (portion having the short diameter S) 51 of the support shaft 5 passes. A fitting portion 6 into which a portion (a portion having a long diameter L) 52 can be fitted.
An elongated hole 6 having 2, 63 is formed. On the upper side of the inner side of the other side plate 2, a narrow retaining portion 71 that allows only the short diameter portion 51 of the support shaft 5 to pass therethrough.
And a downwardly directed guide portion 72 formed on the front side thereof so that the long diameter portion 52 of the support shaft 5 can be loosely fitted thereto, and a retaining portion 71 thereof
And an elongated L-shaped long hole 7 having a wide fitting portion 73 formed on the rear side of the supporting shaft 5 and capable of fitting the long diameter portion 52 of the support shaft 5. With such a configuration, both projections 3, 3
Before assembling to the side plates 2 and 2, the paper cutting cover 4 can be attached neatly as follows (FIGS. 2 to 4).
reference). First, as shown in FIG. 2, the paper cutting cover 4 is tilted so as to be slightly lowered to the right side in the drawing, and one support shaft 5 of the paper cutting cover 4 is fitted into the fitting portion 62 of one of the long holes 6. The other support shaft 5 (on the front side in the figure) is fitted into the lower end of the guide portion 72 of the other long hole 7. Next, the other support shaft 5 is connected to the guide portion 7.
2, the paper cutting cover 4 is tilted to the position shown by the two-dot chain line in FIG. 3, the D-cut portion D of the support shaft 5 is directed upward, and the cover is pushed into the back. The short diameter portions 51, 51 (see FIG. 1) of the shafts 5, 5 are passed through the retaining portions 61, 71 and fitted into the insertion portions 63, 73 on the back side. Then, as shown by the broken line, the paper cutting cover 4
When the left and right protrusions 3 and 3 are assembled to the side plates 2 and 2 with the upper side opened, the paper cutting cover 4 is moved within the range indicated by the dashed arrow B in FIG. (See FIGS. 5 to 7). As described above, when the paper cutting cover 4 is mounted, it is not necessary to expand the side plates 2 at all.
The fitting operation is extremely easy, and the problems such as the occurrence of cracks at the base portions (bent portions) of the side plates 2 and 2 and the removal of the coating are eliminated. The above-mentioned projection 3 for supporting the roll paper (FIGS. 5 to 7)
The base 31 is pivotally supported by the pin 11 at the lower part of the side plate 2, and the lower end of an elastic piece 32 integrally formed extending downward at the back thereof is formed in a circular arc shape inside the lower part of the side plate 2. The tip 33 is brought into contact with the wall by urging and sliding.
As shown in the figure, the side plate 2 is biased so as to protrude inward from the inner opening 21 and swings freely from the position shown in the direction of arrow 12 (see FIG. 6) against the biasing force. It has become. Therefore, when the roll paper is loaded, the projections 3, 3 are pushed up from both ends of the roll paper from below, so that the projections 3, 3 are once turned inside the side plates 2, 2, By the biasing force of the elastic pieces 32, 32, they project inward again and fit into the core holes. In addition, when the used roll core is fitted to both the projections 3 and 3, the old roll core can be taken out at the same time when a new roll paper is mounted. The swing range of the paper cutting cover 4 after being mounted is restricted by the two projections 3 and 3 (see the arrow B in FIG. 3).
Therefore, as described above, the support shafts 5, 5 are provided with the retaining portions 61, 71.
Without being passed through, the state held by the fitting portions 63 and 73 is maintained. Therefore, these two projections 3, 3
Needless to say, the position of the D-cut portion D of the support shaft 5 (the angle with respect to the paper cutting cover 4) may be appropriately set depending on the difference in the position, the shape of the side plates 2 and the like. The length of the guide portion 72 of the other long hole 7 is determined by tilting the paper cutting cover 4 so that one support shaft 5 is connected to the long hole 6.
After fitting into the fitting portion 62, the other support shaft 5 may be set to such an extent that the other support shaft 5 can be fitted into the lower end thereof.
What is necessary is just to respond suitably according to a specification. As described above, according to the paper holder of the present invention, the shafts provided on both sides of the base of the paper cutting cover are D-cut, and one side is provided for supporting the shafts. On the side plate, a long hole having a fitting portion capable of fitting the long diameter portion before and after the retaining portion that allows only the short diameter portion of the support shaft is formed, while the other side plate has only the short diameter portion of the support shaft. A retaining portion to be passed, a downward guide portion formed at the front side thereof to allow the long diameter portion of the support shaft to be loosely fitted, and a fitting formed at the rear side of the removal prevention portion to fit the long diameter portion of the support shaft. Since the inverted L-shaped long hole having the portion is formed, when assembling the paper cutting cover, the paper cutting cover may be inclined to fit the support shaft into the long hole, and it is not necessary to expand both side plates. Since there is nothing at all, mounting workability has been dramatically improved In addition, it is possible to avoid problems such as cracking of the base of the side plate and peeling of the coating.
