Moreover, the shelf support 1c used for the left rear side edge 3c of the shelf 3 is the same as the shelf support 1b, and the shelf support used for the right rear edge 3d of the shelf 3. 1d is the same as the shelf support 1a. Accordingly, only the configuration of the shelf support 1a will be described below, and the description of the configuration of the shelf support 1b, 1c, 1d will be omitted.

<Overall configuration of shelf board support>
Then, the structure of the shelf support 1a in 1st Embodiment is demonstrated, referring FIGS.

  The shelf board support 1 a includes a main body 10 and a shaft member 20 that can be inserted into the insertion hole 2 a of the furniture main body 2 after being fitted into the fitting hole 141 of the main body 10. The main body 10 is a member that supports the shelf board 3 in a state in which it is detachably attached to the insertion hole 2a of the furniture main body 2 via the shaft member 20, and is made of, for example, plastic or metal. The main body unit 10 includes a shelf board placing part 11, a shelf board contact part 12, and an inclined support part 13.

  The shelf mounting part 11 is a substantially rectangular thin plate-like part on which the shelf 3 is placed in a state where the bottom 3t (FIG. 4) of the shelf 3 is supported, and supports the bottom 3t of the shelf 3. A flat upper surface 11a, a lower surface 11b positioned on the back side of the upper surface 11a, side end surfaces 11c and 11d facing each other, and a rear end surface 11e positioned on the rear side (in the direction of arrow d) of the shelf mounting portion 11 Have

  Further, the shelf mounting part 11 includes a shaft member holding part 14 that protrudes toward the lower side (arrow f direction) at a position closer to the front side (arrow c direction). The shaft member holding portion 14 has a substantially cylindrical shape and includes a fitting hole 141 for holding the shaft member 20 in a state of being fitted and fixed. The fitting hole 141 has a small-diameter hole portion that fits with the fitting shaft portion 21 of the shaft member 20, and a large-diameter hole portion that communicates with the small-diameter hole portion and engages with the flange portion 23 of the shaft member 20.

  In addition, the shelf mounting portion 11 has an arcuate support plate 15 that protrudes upward (in the direction of arrow e) from the upper surface 11a along the side end surface 11d that contacts the inner wall surface of the side plate 21 in the furniture body 2. It has. The support plate 15 is formed concentrically with the fitting hole 141, and functions as a portion that supports the side end surface of the shelf plate 3 on the left side (in the direction of arrow a) while abutting. A part of the support plate 15 extends to the inclined support portion 13 and is integrated with the inclined support portion 13.

  The shelf contact portion 12 is a substantially rectangular parallelepiped thin plate member that contacts an end surface (hereinafter also referred to as “front end surface”) 3 f of the shelf plate 3 in the front direction (arrow c direction). The shelf contact portion 12 includes a front surface 12a, a back surface 12b, side end surfaces 12c and 12d facing each other, and an upper end surface 12e and a lower end surface 12f facing each other.

  A width t1 between the front surface 12a and the back surface 12b of the shelf board abutting portion 12 is thinner than a width t0 between the upper surface 11a and the lower surface 11b of the shelf board placement portion 11. Moreover, in the shelf contact part 12, the portion 12cf where the side end face 12c and the lower end face 12f intersect is R-chamfered. This is because the object to be placed on the shelf 3 of the furniture body 2 is not caught when stored or taken out.

  The lower end surface 12 f of the shelf board abutting portion 12 is positioned below (in the direction of arrow f) from the shaft member holding portion 14 of the main body portion 10. Therefore, when the shelf support 1a is viewed from the front surface 12a of the shelf contact portion 12, the presence of the shaft member holding portion 14 of the main body 10 is concealed by the front surface 12a, which is excellent in aesthetics. It has characteristics. In addition, the upper end surface 12e and the lower end surface 12f of the shelf board contact part 12 are contact surfaces when the user grasps the shelf board contact part 12 with a finger.

  A locking claw 16 is formed at the upper end portion of the shelf plate contact portion 12 that is the upper end (direction of arrow e). The locking claw 16 is a claw-like member protruding toward the rear side (in the direction of arrow d) of the shelf board abutting portion 12, and the upper side (in the direction of arrow e) of the shelf board 3 (hereinafter referred to as this). (Also referred to as “upper surface”) 3p (see FIG. 4) and the shelf board 3 is locked in a gripping state in which the shelf board 3 is sandwiched between the upper surface 11a of the shelf board mounting portion 11. The lower end surface 16 a of the locking claw 16 is formed substantially in parallel with the upper surface 11 a of the shelf board mounting portion 11. Further, a chamfered chamfered portion 16 b is formed on the distal end side of the locking claw 16.

  The inclined support portion 13 is a thin plate-like member that is gradually inclined downward (arrow f direction) from the upper surface 11a of the shelf placement portion 11 toward the front side (arrow c direction). It functions as a connecting portion that integrally connects the plate contact portion 12.

  A thickness t2 between the upper surface (arrow e direction) and the lower surface (arrow f direction) of the inclined support portion 13 is substantially the same as the thickness t0 between the upper surface 11a and the lower surface 11b of the shelf placement unit 11. The connection surface of the connection portion 1213 that connects the inclined support portion 13 and the shelf contact portion 12 is formed in an arc shape, and the connection portion 1213 is slightly thicker than the thickness t2 of the inclined support portion 13. ing.

  Thus, as shown in FIG. 4, the main body 10 is engaged with the upper surface 11 a of the shelf mounting part 11 in the inclined support part 13 that connects the shelf mounting part 11 and the shelf contact part 12. When the shelf plate 3 is gripped and held between the lower end surface 16a of the claw 16, a non-contact space spc having a substantially triangular cross section can be formed between the bottom surface 3t of the shelf plate 3 and the inclined support portion 13. It is configured as follows.

<Configuration of shaft member>
Next, the configuration of the shaft member 20 will be described with reference to FIG. The shaft member 20 is formed on the columnar fitting shaft portion 21 inserted into the fitting hole 141 formed in the shaft member holding portion 14 of the main body portion 10 and the inner wall surfaces of the side plates 21 and 2r of the furniture main body 2. A cylindrical insertion shaft portion 22 inserted into the insertion hole 2a, and a disc-shaped flange portion 23 formed between the fitting shaft portion 21 and the insertion shaft portion 22 and having a larger outer diameter than the fitting shaft portion 21. And. In addition, the external shape of the fitting shaft part 21 and the insertion shaft part 22 is not specifically limited, It can change suitably according to the internal shape of the fitting hole 141 and the insertion hole 2a.

<How to use>
With reference to FIG.1 and FIG.4, an example of the usage method of the shelf support 1a in 1st Embodiment is demonstrated. When attaching the shelf board 3 to the furniture body 2, first, the insertion shaft portion 22 of each shelf board support 1a, 1b, 1c, 1d is formed at the same height position formed on the inner wall surface of the side plates 2l, 2r of the furniture body 2 Are inserted into the four insertion holes 2a.

  And after supporting in the state which made the edge part of the rear side (arrow d direction) of the shelf board 3 hold | grip between the shelf board mounting part 11 and the latching claw 16 of the shelf board support tools 1c and 1d, The front side of the shelf board 3 from the upper side (arrow e direction) to the lower side (arrow f direction) with the shelf board 3 placed on the chamfered portion 16b of the locking claw 16 of the plate support 1a, 1b. Press the end in the direction of arrow c.

  At this time, since the shelf contact portion 12 bends forward (in the direction of the arrow c) as indicated by the solid line from the broken line, the shelf placement portion 11 and the locking claw 16 of the shelf support 1a, 1b The shelf plate 3 can be supported while being held between them, and the state where the shelf plate 3 is placed on the shelf plate placement portion 11 can be maintained. In this case, the chamfered portion 16b formed on the locking claw 16 serves as a guide when the shelf plate 3 is pressed, and the shelf plate 3 moves the shelf plate abutting portion 12 to the front side via the chamfered portion 16b. Since it will push to (arrow c direction), the shelf board 3 can be attached smoothly.

  On the other hand, when removing the shelf 3 from the furniture body 2, focusing on the shelf support 1 a, as shown in FIG. 4, the user pushes the locking claw 16 forward (in the direction of arrow c), thereby The contact portion 12 is bent while being tilted forward (in the direction of arrow c) so as to be separated from the shelf plate 3.

  At this time, the shelf support 1a is easily bent due to the presence of the inclined support portion 13 while the shelf contact portion 12 is tilted forward (in the direction of arrow c), and is inclined with respect to the bottom surface 3t of the shelf 3. The contact area with the shelf 3 is reduced by the non-contact space spc formed between the support portion 13 and the support portion 13.

  As a result, the shelf support 1a can easily eliminate the locking state of the locking claw 16 with respect to the upper surface 3p of the shelf 3 with a small force. By performing the same operation also on the shelf support 1b, the end of the front side of the shelf 3 (arrow c direction) is removed from the shelf support 1a, 1b, and the shelf 3 is moved to the front (arrow c) in that state. The shelf 3 can be completely removed from the furniture body 2 by pulling in the direction).

  Further, in the shelf support 1a, the lower end surface 12f of the shelf contact portion 12 is positioned below the inclined support portion 13 (in the direction of the arrow f), and therefore the upper end surface 12e of the shelf contact portion 12 is. And the lower end surface 12f can be easily sandwiched between the fingers of the operator, and the shelf contact portion 12 can be easily bent. That is, the shelf board support 1a is excellent in the handleability at the time of removing the shelf board 3 compared with the past.

  Further, in the shelf board support 1a, a portion 12cf located on the storage space side of the furniture body 2 is R-chamfered on the lower end surface 12f of the shelf board abutting portion 12. For this reason, in the shelf board support 1a, when attaching and removing the shelf board 3, it can prevent an operator's hand from being damaged, and accommodates the accommodations placed on the shelf board 3 of the furniture body 2. It is possible to prevent the contents from being damaged even when performing or taking out.

  Furthermore, since the support plate 15 is provided in the shelf mounting part 11, the entire shelf support 1 a is connected to the inner wall surfaces of the side plates 2 l and 2 r in the furniture body 2 through the support plate 15. It can be pressed. Thereby, the attachment state of the shelf support 1a with respect to the inner wall surface of the side plates 21 and 2r can be maintained stably.

<Example>
The shelf board support 1a of 1st Embodiment is provided with the inclination support part 13 which connects between the shelf board mounting part 11 and the shelf board contact part 12, as shown to FIG. 5 (A). On the other hand, as shown in FIG. 5B, in the conventional shelf support 1z, the shelf support 11z and the shelf contact portion 12z are directly connected to each other, like the shelf support 1a. The inclined support part 13 is not provided. Such a shelf support 1a of the present invention is compared with a conventional shelf support 1z.

  As shown in FIGS. 5A and 5B, in the shelf support 1a and the shelf support 1z, the locking claws 16, 16z are moved by 5 mm to the front side (in the direction of the arrow c) indicated by the thick arrow A. The pressing force required for the analysis was analyzed.

  As a result, as shown in Table 1, it was found that the shelf support 1a requires a force of 15.25N and the conventional shelf support 1z requires a force of 30.7N. Therefore, in the shelf support 1a, the shelf contact portion 12 can be bent with less force than the conventional shelf support 1z. That is, the shelf board 3 can be easily removed from the furniture body 2 by using the shelf support 1a for the furniture body 2 of the furniture 100.

  Next, as shown in FIGS. 5 (A) and 5 (B), the upper side (in the direction of arrow e) indicated by the thick arrow B with respect to the lower end surface 16a of the locking claw 16 and the lower end surface 16za of the locking claw 16z, The amount of displacement of the locking claws 16 and 16z was analyzed assuming a case where a load 13.5 kgf five times that of a shelf board having a weight of 2.7 kg was applied. In addition, since four shelf board support tools 1a-1d are installed in the furniture main body 2, the load applied to the locking claws 16, 16z per piece is 2.7 kgf × 5 ÷ 4 = 3.375 kgf =. 33N.

  As a result, as shown in Table 1, in the shelf support 1a, the displacement of the locking claw 16 is 0.9794 mm, and in the conventional shelf support 1z, the displacement of the locking claw 16z is 0.8623 mm. There was no big difference between them. Therefore, it was found that the shelf support 1a has the same strength as the conventional shelf support 1z. That is, when the shelf support 1a is mounted on the furniture body 2 and transported upside down with the shelf 3 placed, even if the load of the shelf 3 is applied to the lower end surface 16a of the locking claw 16, The state in which the shelf 3 is locked by the shelf supports 1a to 1d can be maintained.

  As described above, in the shelf support 1a, the ease of removing the shelf 3 is improved, and two contradictory effects that the shelf 3 can be firmly supported can be realized at the same time.

[Second Embodiment]
2nd Embodiment adds the improvement to the main-body part 10 of the shelf support 1a of 1st Embodiment. With reference to FIG. 6, the shelf board support 1e of 2nd Embodiment is demonstrated. In addition, about the structure similar to the shelf support 1a of 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  As shown in FIG. 6, the shelf board support 1 e of the second embodiment includes a thin plate-like rib 17 connected to the shelf board contact portion 12, the inclined support portion 13, and the support plate 15. The ribs 17 are integrally connected to the side end surface 12 d of the shelf plate contact portion 12, the side end surface 13 d of the inclined support portion 13, and the upper end edge 15 e of the support plate 15. However, the present invention is not limited to this. For example, the rib 17 may be at least connected to the side end surface 12d of the shelf plate contact portion 12 and the side end surface 13d of the inclined support portion 13, and the upper end edge 15e of the support plate 15 is sufficient. It does not have to be integrally connected with the.

  The shelf support 1e is provided with ribs 17 that are at least connected to the side end surface 12d of the shelf contact portion 12 and the side end surface 13d of the inclined support portion 13, so that the shelf contact portion 12 is bent. The strength at the time of supporting the shelf board 3 can be improved by reducing the amount of the shelf board support 1 of the first embodiment.

[Third Embodiment]
In the third embodiment, an improvement is added to the shelf contact portion 12 of the shelf support 1a of the first embodiment. With reference to FIG. 7, the shelf board support 1f of 3rd Embodiment is demonstrated. FIG. 7 is a side view of the shelf board support 1f of the third embodiment viewed from the right side. In addition, about the structure similar to the shelf support 1a of 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  As shown in FIG. 7, the shelf board contact portion 18 of the shelf board support 1f according to the third embodiment is different from the shelf board contact portion 12 of the shelf board support 1a according to the first embodiment. The thickness t3 in the front-rear direction (arrow cd direction) perpendicular to the shelf plate 3 is in contact with the shelf board 3, that is, the thickness t3 between the front surface 18a and the back surface 18b is from the upper side (arrow e direction) to the lower side (arrow It has a shape that gradually increases toward (f direction). Specifically, the back surface 18 b of the shelf board contact portion 18 in the shelf board contact portion 18 is formed perpendicular to the upper surface 11 a of the shelf board placement portion 11. The front surface 18a is formed so as to gradually move away from the back surface 18b as it goes from the upper side (arrow e direction) to the lower side (arrow f direction).

  The shelf support 1f of the third embodiment is formed such that the thickness t3 of the shelf contact portion 18 gradually increases from the upper side (arrow e direction) toward the lower side (arrow f direction). For this reason, the amount of bending of the shelf contact portion 18 can be made smaller than that of the shelf support 1 of the first embodiment to improve the strength when supporting the shelf 3, and the shelf 3 is mounted. Even when transported upside down in the placed state, the state in which the shelf 3 is locked by the shelf support 1f can be maintained.
