Description

  The present invention relates to a bookshelf in which a bottom plate, a top plate, and a shelf plate are arranged between a pair of side plates.

  Boxes such as bookshelves have a large occupied space and a high transportation cost when completed. In order to reduce the transportation cost, the box is usually divided into parts and transported to the site and assembled.

FIG. 17 is an external perspective view showing a conventional box 101. 18 is an exploded perspective view of the main part of FIG.
For example, the appearance of the box 101 shown in FIG. 17 is configured by a bottom plate 102, a pair of side plates 103 and 104, a front plate 105, a rear plate 106, and a lid 110. The front plate 105, the rear plate 106, and the lid 110 are detachably attached to the pair of side plates 103 and 104. As shown in FIG. 18, the pair of side plates 103 and 104 are fixed to the bottom plate 102 via a hinge 107. The rear plate 106 has a receiving bracket 109 screwed to contact surfaces 106 a and 106 b that contact the pair of side plates 103 and 104. A shaft 108 is fixed to the inner wall of the pair of side plates 103 and 104 at a position corresponding to the bracket 109. The rear plate 106 is fixed to a pair of side plates 103 and 104 erected vertically with respect to the bottom plate 102 by engaging the shaft 108 with the groove 109a of the bracket 109, respectively. The rear plate 106 has a metal fitting 109 fixed to a notch groove 106c formed by notching the contact surfaces 106a and 106b so that there is no gap between the pair of side plates 103 and 104. The notch groove 106 c is provided larger than the receiving metal fitting 109 and opens on the surface side forming the inner surface of the box 101 so that the receiving metal 109 cannot be seen from the outside after the box 101 is assembled. Since the front plate 105 is formed in the same manner as the rear plate 106, the description thereof is omitted.

  Such a box 101 is folded in such a manner that the pair of side plates 103 and 104 are tilted toward the bottom plate 102 and overlapped with the bottom plate 102 with the front plate 105, the rear plate 106, and the lid 110 removed. Space can be reduced and transportation costs can be reduced. At the site, the pair of side plates 103 and 104 are rotated with respect to the bottom plate 102, and the shaft 108 of the side plates 103 and 104 is engaged with the brackets 109 of the front plate 105 and the rear plate 106. The main body of the box 101 can be completed without using it (see, for example, Patent Document 1).

  However, in the conventional box 101, the manufacturer forms the notch groove 106c larger than the width dimension and the longitudinal dimension of the bracket 109, and screws the bracket 109 at an arbitrary position of the notch groove 106c. Since the positional relationship between the front plate 105 and the rear plate 106 and the pair of side plates 103 and 104 and the bottom plate 102 is determined by the fixing position of the receiving bracket 109, depending on the fixing position of the receiving bracket 109, There was a case where a gap was formed between the side plates 103 and 104 and the bottom plate 102. In particular, in recent years, box products are manufactured not only in Japan but also overseas for the purpose of cost reduction, and there are many parts manufacturing workers. Therefore, unifying the fixing position of the metal fitting 109 is very important for stabilizing the product quality. In particular, when the box is a bookshelf, the balance after assembling becomes unstable if the fixing position of the metal fitting 109 is not unified, and a problem such as tilting when a book is stored occurs.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a bookshelf that can easily align the parts by unifying the fixing positions of the brackets.

The bookshelf according to the present invention has the following configuration.
(1) In a bookshelf having a pair of side plates and a plurality of installation plates provided between the pair of side plates, the plurality of installation plates are provided with a groove that is formed in a longitudinal direction on one side. And a pair of side plates engaged with the groove of the bracket at a mounting position of the bracket with the bracket. The member is fixed, and the installation plate with the receiving bracket is provided in the same width as the width of the receiving bracket, and is provided perpendicular to the fixed surface to which the receiving bracket is fixed and the long side of the fixed surface. A vertical plane, and the bracket is aligned with an end of the fixed plane and the vertical plane.

(2) In the invention described in (1), the mounting plate with the receiving bracket is made of a composite material in which thin plates are fixed to both surfaces of a plate-like core material having the same thickness as the width dimension of the receiving bracket. The thin plate protrudes laterally from the end portion facing the side surface of the core material, the fixed surface is constituted by the end portion of the core material, and the vertical surface is constituted by the thin plate.

(3) In the invention described in (2), the mounting plate with a receiving bracket closes a gap formed between the thin plates at an end portion orthogonal to the end portions facing the pair of side plates. Having a decorative plate attached to the.

(4) In the invention described in (3), the installation plate with a receiving bracket has a reinforcing block fixed at a position inside the decorative plate at an end of the fixed surface, and the receiving bracket has the reinforcement It is being fixed to the said fixed surface in the state contact | abutted to the block.

  The bookshelf with the above configuration is provided at the end facing the pair of side plates of the mounting plate with the receiving bracket, on a fixed surface provided with the same width as the width of the receiving bracket, and on the long side of the fixed surface. And a vertical surface provided perpendicular to the surface. By positioning the receiving bracket on the end of the fixed surface and the vertical plane and fixing the receiving bracket to the mounting plate with the receiving bracket, the receiving bracket is uniquely positioned with respect to the mounting plate with the receiving bracket. Therefore, if the receiving bracket is aligned with the end of the fixed surface of the mounting plate with the receiving bracket and fixed to the mounting plate with the receiving bracket, anyone can fix the receiving bracket at the same position of the mounting plate with the receiving bracket. It is possible to unify the fixing position of the bracket. In addition, since the fixing position of the receiving bracket is unified and the positional relationship between the engaging member and the receiving bracket is not easily displaced, it is easy to align the pair of side plates and the installation plate with the receiving bracket.

  The bookshelf having the above-described configuration constitutes a mounting plate with a receiving bracket made of a composite material in which thin plates are fixed on both surfaces of a plate-like core material having the same thickness as the width of the receiving bracket. In the erection plate with the receiving metal fitting, the thin plate protrudes laterally from the end portion facing the side surface of the core material, the fixing surface is constituted by the end portion of the core material, and the vertical surface is constituted by the thin plate. As a result, the distance between the vertical surfaces is stabilized to the width of the metal fitting by the thickness of the core material, so that both ends of the metal fitting in the longitudinal direction are in contact with the thin plate and the end orthogonal to the longitudinal end of the metal fitting By aligning the portion with the end of the fixed surface, the bracket can be more accurately positioned and fixed with respect to the installation plate with the bracket.

  Since the bookshelf having the above-described configuration has a decorative plate attached to the end portion orthogonal to the end portion facing the pair of side plates of the mounting plate with the bracket so as to close the gap formed between the thin plates, When the attached construction plate is fixed to the pair of side plates, the receiving bracket is hidden by the thin plate and the decorative plate and cannot be seen from the outside.

  The bookshelf configured as described above is engaged with the engaging member in the groove of the bracket by bringing the bracket into contact with the reinforcing block fixed to the inner side of the decorative plate at the end of the stationary surface and fixing the bracket to the stationary surface. Since the reinforcing block receives the force generated when the mounting plate with the receiving bracket is attached to the pair of side plates, the decorative plate is destroyed by the force generated when the engaging member is engaged with the receiving bracket. Can be prevented.

The other metal fitting 12 is fixed to the top plate 6 in the same manner as the one metal fitting 12, with the end 12 c abutting against a reinforcing block 36 provided on the rear side of the housing recess 35.

  As shown in FIG. 4, the shelf board 8 fixes the back surface part 8b to the rear-end part of the shelf board part 8a, and prevents the book accommodated in the shelf board 8 from falling to the back of the bookshelf 1. The shelf plate portion 8 a has a locking metal fitting 16 screwed to the end facing the side surfaces 2 and 3. A locking hole 16 a is formed in the locking metal 16 at a position corresponding to the catch 9 of the side plates 2 and 3.

FIG. 7 is a cross-sectional view taken along CC of FIG. FIG. 8 is an external perspective view of a pair of side plates. FIG. 9 is an enlarged view of a portion D in FIG.
Since the side plates 2 and 3 have the same configuration, only the side plate 2 will be described here. As shown in FIG.7 and FIG.8, as for the side plate 2, a pair of receiving fixture 9 is being fixed in parallel with the inner surface. In the side plate 2, the receiving tool 9 is fixed to the mounting grooves 2 a and 2 a formed between the mounting position of the bottom plate 5 and the mounting position of the top plate 6 by the fixing screw 11, and the receiving tool 9 does not protrude from the surface. As shown in FIG. 8, the side plate 2 holds the shelf plate 8 via a latching claw 10 that is hooked in a latching hole 9 a of the catching tool 9. As shown in FIG. 9, the latching claw 10 is substantially S-shaped, and is detachably hooked to the latching hole 9 a and the latching hole 16 a of the shelf board 8, so that the pair of side plates 2 have an arbitrary height. The shelf board 8 can be easily attached.

  Further, as shown in FIG. 7, the side plate 2 has shoulder screws 14 fixed at positions corresponding to the brackets 12 of the base 4 and the top plate 6, and one shoulder screw at a position corresponding to the back plate 7. 14 is fixed. Each shoulder screw 14 has a male screw 14c screwed into the side plate 2 until the collar portion 14d abuts against the surface of the side plate 2, and the positional relationship between the groove 12a of each bracket 12 and the head 14a of each shoulder screw 14 is constant. Has been.

<Assembly method>
Next, a method for assembling the bookshelf 1 will be described. 11 to 15 are assembly explanatory views of the bookshelf 1.
As shown in FIG. 11, first, the shoulder screws 14 provided below the pair of side plates 2 and 3 are respectively aligned with the insertion portions 12d of the metal fittings 12 provided on the base 4, and the base 4 is moved downward. Slide. As a result, the head 14a of each shoulder screw 14 is guided to the inside of the groove 12a of the bracket 12 and is hooked on both ends of the groove 12a, and cannot be removed. As a result, the base 4 is fixed between the pair of side plates 2 and 3 as shown in FIG.

  Next, as shown in FIG. 13, the bottom plate 5 is placed on the base 4. The bottom plate 5 is installed so that the positioning members 17, 17 are brought into contact with the inside of the base 4, and is prevented from being displaced in the horizontal direction with respect to the base 4 and the pair of side plates 2, 3. The shoulder screws 14 provided above the pair of side plates 2 and 3 are respectively aligned with the insertion portions 12d of the receiving bracket 12 provided on the top plate 6, and the top plate 6 is slid horizontally toward the rear. As a result, the head 14a of each shoulder screw 14 is guided to the inside of the groove 12a of the bracket 12 and is hooked on both ends of the groove 12a, and cannot be removed. As a result, the top plate 6 is attached between the pair of side plates 2 and 3.

  Next, as shown in FIG. 14, the shoulder screws 14 provided at the rear of the pair of side plates 2 and 3 are respectively aligned with the insertion portions 12 d of the metal fittings 12 provided at both ends of the back plate 7. The fitting projection 7 a of the back plate 7 is fitted into the fixing groove 5 a of the bottom plate 5. As a result, the head 14a of each shoulder screw 14 is guided to the inside of the groove 12a of the bracket 12 and is hooked on both ends of the groove 12a, so that it cannot be removed. As a result, the back plate 7 is fixed to the pair of side plates 2 and 3. Further, the back plate 7 is fixed perpendicularly to the bottom plate 5 by engaging the fitting projection 7 a with the bottom plate 5. The bottom plate 5 is sandwiched and fixed between the back plate 7 and the base 4.

  Thus, the book rack 1 slides the base 4, the top plate 6, and the back plate 7 between the pair of side plates 2 and 3 without using a tool, and the shoulder screw 14 is inserted into the groove 12 a of the bracket 12. By simply engaging, the base 4, the bottom plate 5, the top plate 6, and the back plate 7 can be fixed to the pair of side plates 2 and 3 without any gap, and the outer frame can be assembled easily. The outer frame of the bookshelf 1 has a pair of side plates 2, 3 supported up and down by the base 4 and the top plate 6 a of the top plate 6 to ensure parallelism, and the back plate 7 and the back of the top plate 6. Since it is supported by the part 6b so as not to tilt left and right, it can be assembled with good balance.

  In the rack 1, the base 4 is covered with the bottom plate 5 so that the receiving metal 12 exposed inside the front plate 21 and the rear plate 22 of the base 4 cannot be seen from the outside. In addition, the bracket 12 of the top plate 6 and the back plate 7 and the shoulder screws 14 of the pair of side plates 2 and 3 are housed in a space surrounded by the pair of thin plates 32 and 32 and the decorative plate 33, I can't see it later. Therefore, the outer frame of the bookshelf 1 is assembled without exposing a metal such as a screw to the outside, and the aesthetics are good.

  When the base 4, the top plate 6, and the back plate 7 are attached to the pair of side plates 2 and 3, the shoulder screw 14 may hit the inner wall of the groove 12 a of the metal fitting 12. Even in this case, the impact with which the shoulder screw 14 hits the receiving bracket 12 acts on the reinforcing block 36 and does not act on the decorative plate 33. Therefore, the decorative plate 33 is not damaged by the impact of the shoulder screw 14 hitting the receiving bracket 12, and the assembly work is easy to perform.

  When the outer frame is completed as described above, the shelf board 8 is attached to an arbitrary position as shown in FIG. Specifically, the latching claws 10 are hooked in the arbitrary latching holes 9 a of the catches 9 fixed to the pair of side plates 2 and 3. Then, the hooking claw 10 is hooked in the hooking hole 16 a provided in the locking bracket 16 of the shelf board 8. Thereby, the shelf board 8 is attached to the pair of side plates 2 and 3 through the latching claws 10 without any gap. Since the shelf plate 8 is attached so as to be hooked on the pair of side plates 2 and 3 using the latching claws 10 formed by forming a metal plate into an S shape, there is no large gap between the pair of side plates 2 and 3. As a result, the assembly of the bookshelf 1 is completed.

<Effect>
The bookshelf 1 according to the present embodiment is provided at the end facing the pair of side plates 2 and 3 of the front plate 21 and the rear plate 22 constituting the base 4 so as to have the same width as the width of the bracket 12. The housing grooves 21 a, 21 b, 22 a, and 22 b are provided that include a fixed surface 37 to which 12 is fixed and a vertical surface 38 that is provided perpendicular to the long side of the fixed surface 37. In addition, a storage recess 35 made up of a fixed surface 37 and a pair of vertical surfaces 38 is provided at the ends of the top plate 6 and the back plate 7 facing the pair of side plates 2 and 3. The bracket 12 is aligned with the end of the fixing surface 37 and the vertical surface 38 and fixed to the base 4, the top plate 6, and the back plate 7, respectively. It is uniquely positioned with respect to the base 4, the top plate 6 and the back plate 7. Therefore, if the bracket 12 is aligned with the end of the fixed surface 37 of the base 4, the top plate 6 and the back plate 7 and the vertical surface 38 and fixed to the base 4, the top plate 6 and the back plate 7, whoever However, the receiving bracket 12 can be fixed to the same position of the base 4, the top plate 6 and the back plate 7, and the fixing position of the receiving bracket 12 can be unified. In addition, since the fixing position of the bracket 12 is unified and the positional relationship between the shoulder screw 14 and the bracket 12 is less likely to shift, the pair of side plates 2 and 3 and the base 4 or the top plate 6 and the back plate 7 Easy to align. This effect is particularly effective when a large number of workers manufacture the parts of the bookshelf 1.

  The bookshelf 1 according to the present embodiment includes a top plate 6 and a back plate 7 made of a composite material in which thin plates 32 and 32 are fixed to both surfaces of a plate-like core member 31 having the same thickness as the width of the metal fitting 12. is doing. The top plate 6 and the back plate 7 have thin plates 32, 32 projecting sideways from the end portions facing the side surfaces 2, 3 of the core material 31, and a fixed surface 37 is constituted by the end portions of the core material 31, A vertical surface 38 is constituted by the thin plates 32 and 32. As a result, the interval between the vertical surfaces 38 is stabilized to the width of the metal fitting 12 by the thickness of the core member 31, so that both longitudinal ends of the metal fitting 12 are brought into contact with the thin plates 32 and 32 and the metal plate 12 is arranged in the longitudinal direction. By positioning the end 12b (or 12c) orthogonal to the end to the end of the fixing surface 37, the bracket 12 can be positioned and fixed more accurately with respect to the top plate 6 and the back plate 7. Can do.

  The bookshelf 1 of the present embodiment closes the gap formed between the thin plates 32 and 32 at the end portions orthogonal to the end portions facing the pair of side plates 2 and 3 of the top plate 6 and the back plate 7. Since the decorative plate 33 is attached to the top plate 6 and the back plate 7 when the top plate 6 and the back plate 7 are fixed to the pair of side plates 2 and 3, the metal fitting 12 is hidden by the thin plates 32 and 32 and the decorative plate 33 and cannot be seen from the outside. .

  The bookshelf 1 of the present embodiment has the shoulder screw 14 fixed to the fixing surface 37 by bringing the metal fitting 12 into contact with the reinforcing block 36 fixed to the inner side of the decorative plate 33 at the end of the fixing surface 37. Since the reinforcing block 36 receives the force generated when the top plate 6 and the back plate 7 are attached to the pair of side plates 2 and 3 by engaging with the groove 12a of the receiving bracket 12, the shoulder screw 14 is attached to the receiving bracket. It is possible to prevent the decorative plate 33 from being broken by the force generated when engaging with the door 12.

  The book rack 1 according to the present embodiment includes a shoulder plate 14 erected on the side plates 2 and 3 after being assembled, and a coupling portion between the top plate 6 and the receiving bracket 12 fixed to the back plate 7. It fits in the space surrounded by the thin plate 32 and the decorative plate 33 of the back plate 7 and cannot be seen from the outside. Further, the connecting portion between the shoulder screws 14 of the side plates 2 and 3 and the receiving metal fitting 12 fixed to the base 4 is also hidden by the thin plate 32 and the bottom plate 5 of the top plate 6 and cannot be seen from the outside. Therefore, the bookshelf 1 looks as if it is assembled without using metal parts such as the shoulder screw 14 and the receiving bracket 12 and has a good appearance.

In addition, this invention is not limited to the said embodiment, Various application is possible.
In the above embodiment, the reinforcing block 36 is fixed to the fixing surface 37. However, the reinforcing block 36 may be omitted as long as the decorative plate 33 can withstand an impact.
In the above embodiment, the shoulder screw 14 is used as an example of the engaging member. However, a pin that can be engaged with the groove 12 a of the metal fitting 12 may be press-fitted and fixed to the side plates 2 and 3.
