Abstract

<P>PROBLEM TO BE SOLVED: To provide an assembled shelf which allows efficient assembly work. <P>SOLUTION: A hinge body 4 for freely swingably connecting a pair of side face bodies to a back surface body includes: a first hinge body 41 provided with an engaging pin 41h of a shaft-like part, and attached to the back beam 22 of the back surface body; and a second hinge body 42 provided with an engaging hole 42h to which the engaging pin 41h is inserted so as to be freely turned and freely inserted and removed, and attached to the side beam 32 of the side face body. Thus, since the engaging pin 41h of the first hinge body 41 is configured so as to be freely attached and detached to/from the engaging hole 42h of the second hinge body 42, the back surface body and the side face bodies are not connected to each other before assembly (before connecting the back beam 22 and the side beam 32). Thus, even when the assembled shelf is enlarged and the back surface body or a pair of side face bodies is reduced in weight, since the back surface body and a pair of side face bodies can be separately carried, the efficiency of the assembly work is improved. <P>COPYRIGHT: (C)2011,JPO&INPIT

Japanese Patent Laying-Open No. 2001-70060 (FIG. 5)

  However, in the conventional assembly-type shelf described above, the connecting member 5 is attached first (the connecting member 5 is attached to the left and right bodies 2 and 3 and the back body 1 from before assembly). The bodies 2 and 3 and the back body 1 must be handled as a unit. Therefore, when the assembly-type shelf increases in size and weight, it is difficult for the operator to stand up or carry the integrated back body 1 and left and right bodies 2 and 3 alone. There was a problem that it took time to assemble the shelf.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an assembly-type shelf capable of efficiently performing an assembly operation.

Means for Solving the Problems and Effects of the Invention

  In order to achieve this object, according to the assembly-type shelf according to claim 1, the pair of side bodies disposed on both sides of the back body are swingably coupled to the back body by the hinge body. . The hinge body includes a first hinge body attached to one of the back body and the side body, and a second hinge body attached to the other of the back body and the side body, and is formed in the first hinge body. By inserting the shaft-like swing shaft into the engagement hole formed in the second hinge body, the side body is swingably and detachably coupled to the back side. Therefore, before the assembly, the back body and the pair of side bodies are not coupled to each other. Therefore, even if the assembly-type shelf is enlarged and the back body and the pair of side bodies are heavy, the back body and the pair of side bodies can be carried separately, so that the efficiency of the assembly work can be improved. is there.

  Further, when the first hinge body and the second hinge body are attached to the back beam and the side beam before assembly, respectively, the first hinge body has a swing shaft, and therefore the swing shaft is engaged. A pair of side bodies can be swingably and detachably coupled to the back body simply by being inserted into the holes. Therefore, the work process of the assembly work can be reduced as compared with the case where the first hinge body and the second hinge body are respectively attached to the back beam and the side beam at the time of assembly. Therefore, there is an effect that the efficiency of the assembly work can be improved.

  According to the assembly-type shelf according to claim 2, when the main body portion is fitted in the opening portion, the protruding portion protrudes through the notch portion, and the first hinge body and the second hinge body are connected to the back beam and the side. Attached to the beam. Therefore, in addition to the effect produced by the assembly-type shelf according to claim 1, the first hinge body and the second hinge body can be respectively attached to the back beam and the side beam without using a tool or the like. There is an effect that can be easily performed.

  Furthermore, since the main body portions of the first hinge body and the second hinge body are fitted in the openings of the back beam and the side beams, the resin main body portions are surrounded by the metal peripheral walls of the back beam and the side beams. Therefore, in addition to the effect which the assembly-type shelf of Claim 1 shows, even if the 1st hinge body and the 2nd hinge body are resin, the 1st hinge body and the 2nd hinge body, and the back beam and the side beam The rigidity at the connecting portion can be ensured. Therefore, the rigidity of the assembled shelf as a whole can be secured and a strong structure can be obtained.

  According to the assembly-type shelf according to claim 3, when the main body portion of the first hinge body or the second hinge body is fitted into the opening of the support beam, the first hinge body or the second hinge is inserted through the notch portion. The protrusion of the body protrudes from the support beam to the outside. Such a protrusion is provided with a shaft-like rocking shaft or engagement hole, and on the other hand, the protrusion protruding outside from the side beam via the notch is provided with a rocking shaft or engagement on the support beam side. An engagement hole or a swing shaft is provided corresponding to the joint hole. Therefore, the support beam and the pair of side beams can be coupled by inserting the swing shaft into the engagement hole.

  As described above, since the pair of side beams and the support beam can be coupled using the first hinge body and the second hinge body, the coupling structure of the pair of side beams and the support beam is combined with the pair of the support beam and the back beam. It can be formed in the same structure as the structure, and the parts can be shared. Therefore, in addition to the effects achieved by the assembly-type shelf according to claim 2, the cost due to the common use of parts compared to the case where the pair of side beams and the support beams are formed in a joint structure different from the pair of support beams and the back beams. There is an effect that reduction can be achieved.

  In addition, since the protrusion protruding outside from the support beam via the notch is disposed above the protrusion protruding outside from the side beam via the notch, the swing shaft is located in the engagement hole. When inserted, the protrusion protruding outward from the support beam is supported by the protrusion protruding outward from the side beam. Therefore, in addition to the effect exhibited by the assembly-type shelf according to claim 2, there is an effect that the support beam can be supported by the pair of side beams only by inserting the swing shaft into the engagement hole.

  According to the assembled shelf according to claim 4, the first hinge body and the second hinge body face outward from the outer peripheral surface at the other end opposite to the one end fitted into the opening of the main body. Thus, the flange protrudes, and the flange comes into contact with the end faces of the back beam, the side beam, and the support beam when the main body portion is fitted in the opening. The flange that is in contact with the end faces of the back beam, side beam, and support beam is supported when the end face of the support beam and the end face of the side beam are brought into contact with each other with the swing shaft inserted into the engagement hole. It is sandwiched between the end face of the beam and the end face of the side beam. Therefore, since the flange is pressed by the end face of the back beam or the support beam and the end face of the side beam, the resin flange is deformed and comes into close contact with the end face of the back beam or the support beam and the end face of the side beam.

  Therefore, in addition to the effect exhibited by the assembly-type shelf according to claim 3, the flange is brought into contact with the end surfaces of the back beam, the side beam, and the support beam when the main body portion is fitted in the opening. Adhesiveness between the end face of the support beam or the end face of the side beam and the flange can be improved, and the back beam or the support beam and the side beam can be firmly coupled.

  Further, since the flange is sandwiched between the end face of the back beam or the support beam and the end face of the side beam, the flange is interposed between the end face of the back beam and the end face of the side beam. Therefore, even if the side body is swung with respect to the back body, the flange that contacts the end face of the back beam interferes with the flange that contacts the end face of the side beam, and the end face of the back beam and the end face of the side beam interfere. do not do. Therefore, in addition to the effect exhibited by the assembly-type shelf according to the third aspect, there is an effect that it is possible to prevent the generation of noise due to interference between the end surface of the back beam and the end surface of the side beam during the assembly operation.

  According to the assembled shelf of claim 5, the support beam, the back beam, and the pair of side beams are provided with flanges on both end surfaces formed so as to be inclined with respect to a cross section perpendicular to the longitudinal direction thereof. The support beam, the pair of side beams, and the back beam are connected in a frame shape by abutting and abutting the flanges. Therefore, the support beam, the pair of side beams, and the back beam can receive the load in both directions of the load acting in the longitudinal direction and the load acting in the direction orthogonal to the longitudinal direction at their end faces (flange). it can. Therefore, in addition to the effect of the assembled shelf according to claim 4, when the support beam, the pair of side beams and the back beam are connected in a frame shape, the strength of the frame-like member connected in the frame shape is improved. Therefore, even when the pair of side bodies are swingably and detachably coupled to the back body by the hinge body, there is an effect that the strength of the assembly-type shelf can be improved.

  In addition, even when the inclined end surfaces of the back beam, the side beam, and the support beam are processed, there is a variation in processing accuracy, and even when an error occurs in the inclination angle at the inclined both end surfaces. The error of the inclination angle can be absorbed by the deformation amount of the flanges respectively brought into contact with the both end faces. Therefore, in addition to the effect produced by the assembly-type shelf according to claim 4, even if errors occur in the inclination angles at both end faces when machining the both end faces of the back beam, the side beam, and the support beam, the back beam and the side There is an effect that the beam and the support beam can be firmly connected in a frame shape.

  According to the assembly-type shelf of claim 6, the swing shaft is formed in a tapered shape having a smaller diameter on the distal end side in the insertion direction into the engagement hole than on the base side connected to the protrusion. The hole is formed in a tapered shape having a smaller diameter on the lower end side than on the upper end side of the engagement hole, corresponding to the tapered shape of the swing shaft. Therefore, when the swing shaft is to be inserted into the engagement hole from the opposite direction to the insertion direction (from the lower end side of the engagement hole, which is the back side of the swing shaft insertion direction), the swing shaft is inserted into the inner wall of the engagement hole. The rocking shaft cannot be inserted into the engagement hole. Therefore, in addition to the effect produced by the assembled shelf according to any one of claims 2 to 5, there is an effect that it is possible to prevent erroneous assembly from occurring in the operation of inserting the swing shaft into the engagement hole.

  In addition, the outer diameter at the tip of the swing shaft is formed larger than the inner diameter of the engagement hole at the upper end on the front side of the swing shaft in the insertion direction. When inserting, it can prevent that the front-end | tip of a rocking | fluctuation shaft and the inner wall in the upper end of an engagement hole interfere. Therefore, in addition to the effect of the assembled shelf according to any one of claims 2 to 5, there is an effect that the operation of inserting the swing shaft into the engagement hole can be easily performed.

  According to the assembled shelf of claim 7, the engagement hole is formed through the protrusion, the screw hole is formed from the tip of the swing shaft inserted into the engagement hole toward the base, and Since the head portion of the fastening member has an outer diameter larger than the inner diameter at the lower end of the engagement hole, when the shaft portion connected to the head portion is screwed into the engagement hole, the head portion is arranged on the protrusion of the first hinge body. The swing shaft provided is fixed to the protrusion of the second hinge body. Therefore, the relative movement of the swing shaft with respect to the engagement hole is restricted. Therefore, in addition to the effect which the assembly-type shelf of Claim 6 has, there exists an effect that it can prevent that a rocking | fluctuation shaft falls off from an engagement hole.

  As shown in FIG. 4A and FIG. 4B, the second hinge body 42 is a member for oscillating and detachably connecting the side beam 32 to the back beam 22. The side beam 32 is attached while being made of a resin material. The second hinge body 42 includes a main body portion 42c formed so as to be fitted in the opening portion 32c of the side beam 32, a rib 42d protruding from the upper surface and the lower surface of the main body portion 42c, and an opening portion of the main body portion 42c. The flange 42a is formed to project outward from the outer peripheral surface at the other end (the right end in FIG. 3 (a)) opposite to the one end fitted in the 32c, and the fastening hole (see FIG. (Not shown), a plurality of lightening portions 42f1 and 42f2 (left side in FIG. 2 (d)) recessed in the back side (see FIG. 2 (d)), and a semicircular shape protruding from the outer peripheral surface of the main body portion 42c. The projection 42g is provided, and the engagement hole 42h is formed through the projection 42g. The flange 42a, step 42c, rib 42d, fastening hole (not shown) and the lightening portions 42f1 and 42f2 of the second hinge body 42 are the flange 41a, step 41c, rib 41d, Since it is formed in the same manner as the fastening hole 41e and the thinned portions 41f1 and 41f2, description thereof will be omitted.

  As shown in FIGS. 3A and 3B, the protrusion 42g is a coupling portion with the first hinge body 41 (protrusion 41g), and an engagement hole is formed at the approximate center of the protrusion 42g. 42h is formed through.

  The engagement hole 42h is a hole into which the engagement pin 41h is inserted. When the engagement pin 41h is inserted into the engagement hole 42h, the engagement hole 42h is second with respect to the protrusion 41g of the first hinge body 41. The protrusion 42g of the hinge body 42 is coupled to be swingable. Further, when the engaging pin 41h is pulled out from the engaging hole 42h, the coupling between the protrusion 41g of the first hinge body 41 and the protrusion 42g of the second hinge body 42 is released. Therefore, the engaging pin 41h is detachably coupled to the protrusion 42g of the second hinge body 42.

  As shown in FIG. 3B and FIG. 4B, the engagement hole 42h corresponds to the tapered shape of the engagement pin 41h, and is on the upper end side that is the front side in the insertion direction of the engagement pin 41h (FIG. 3). The lower end side (lower side in FIG. 3B), which is the back side in the insertion direction of the engagement pin 41h, is formed in a tapered shape having a smaller diameter than (b) upper side.

  Therefore, when the engagement pin 41h is to be inserted from the lower side of the engagement hole 42h (the lower side in FIG. 3B), the engagement pin 41h interferes with the inner wall of the engagement hole 42h. It cannot be inserted into the engagement hole 42h. Therefore, it is possible to prevent erroneous assembly during the operation of inserting the engagement pin 41h into the engagement hole 42h.

  Further, since the outer diameter at the tip of the engagement pin 41h (lower end in FIG. 3B) is smaller than the inner diameter at the upper end of the engagement hole 42h (upper end in FIG. 3B), the tip of the engagement pin 41h. Can be prevented from interfering with the tip of the engagement pin 41h and the inner wall at the upper end of the engagement hole 42h. Therefore, the engagement pin 41h can be easily inserted into the engagement hole 42h.

  As shown in FIG. 3B, the fastening bolt 44 is a member for preventing the engagement pin 41h from dropping out of the engagement hole 42h, and is the same as the first hinge body 41 and the second hinge body 42. Further, it is made of a resin material. The shaft portion 44a is screwed into the screwing hole 41h1, while the head portion 44b is formed so that the outer diameter thereof is larger than the inner diameter at the lower end (the lower end in FIG. 3B) of the engaging hole 42h.

  As shown in FIG. 3 (b), the head 44b of the fastening bolt 44 is formed with an outer diameter larger than the inner diameter at the lower end (lower end of FIG. 3 (b)) of the engagement hole 42h. When the shaft portion 44a that is continuously provided is screwed into the screwing hole 41h1, the head 44b of the fastening bolt 44 is located not only at the distal end surface of the engaging pin 41h but also at the outer periphery of the engaging pin 41h. The engagement pin 41h is also fixed to the lower surface of the protrusion 42g of the body 42, and the protrusion 42g of the second hinge body 42 is fixed. Therefore, since the relative movement of the engagement pin 41h with respect to the engagement hole 42h is restricted, it is possible to prevent the engagement pin 41h from dropping from the engagement hole 42h. Further, since the head portion 44b of the fastening bolt 44 is brought into contact with the lower surface of the protrusion 42g of the second hinge body 42, the head portion 44b of the fastening bolt 44 protrudes from a recess formed on the upper surface of the back beam 22. Can be surely prevented. Therefore, it is possible to prevent the shelf board 6 from interfering with the head portion 44b of the fastening bolt 44.

  Next, referring to FIG. 4 and FIG. 5, the step of attaching (fixing) the first hinge body 41 to the back beam 22, the second hinge body 42 can swing with respect to the first hinge body 41, and The process of detachably coupling will be described.

  As shown in FIG. 4A, the main body portion 41 c of the first hinge body 41 is accommodated in the internal space of the back beam 22 by being fitted into the opening 22 c of the back beam 22, so that the first hinge body 41 is attached to the back beam 22. When the main body portion 41 c of the first hinge body 41 is fitted into the opening 22 c of the back beam 22, the projecting portion 41 g is projected to the outside through the cutout portion 22 d of the back beam 22 and the flange 41 a is projected to the back beam 22. In contact with the end face. Then, the first hinge body 41 is fixed to the back beam 22 by screwing the bolt B inserted into the insertion hole 22e into the fastening hole 41e. Similar to the first hinge body 41, the second hinge body 42 is also fixed to the side beam 32.

  As shown in FIG. 4B, when the engaging pin 41h is inserted into the engaging hole 42h, the protrusion 41g of the first hinge body 41 is located above the protrusion 42g of the second hinge body 42 (FIG. 3). (B) It is arranged on the upper side. Therefore, the second hinge body 42 is swingable with respect to the first hinge body 41 and detachable in a state where the protrusion 41g of the first hinge body 41 is supported by the protrusion 42g of the second hinge body 42. Combined with

  Thereafter, the shaft portion 44a of the fastening bolt 44 is screwed into the screw hole 41h1 in order to prevent the engagement pin 41h from falling off the engagement hole 42h. When the side beam 32 is swung with respect to the back beam 22 around the engaging pin 41h, the flange 41a that contacts the end surface of the back beam 22 and the flange 41a that contacts the end surface of the side beam 32 are abutted. As shown in FIG. 5A, the flanges 41 a and 42 a are sandwiched between the end face of the back beam 22 and the end face of the side beam 32.

  As described above, the engaging pin 41h is configured to be detachable from the protrusion 42g of the second hinge body 42, so that the back body 2 before assembly (before the back beam 22 and the side beam 32 are coupled). (See FIG. 2A) and the side body 3 (see FIG. 2A) are not coupled to each other. Therefore, even when the assembly-type shelf 1 (see FIG. 2A) is enlarged and the back body 2 and the pair of side bodies 3 are increased in weight, the back body 2 and the pair of side bodies 3 are carried separately. it can. Therefore, the efficiency of the assembly work can be improved.

  Further, since the first hinge body 41 and the second hinge body 42 are attached to the back beam 22 and the side beam 32, respectively, before assembling, the rear body can be simply inserted into the engagement hole 42h. The side body 3 (side beam 32) can be swingably coupled to 2 (back beam 22). Therefore, the efficiency of the assembly work can be improved as compared with the case where the first hinge body 41 and the second hinge body 42 are respectively attached to the back beam 22 and the side beam 32 at the time of assembly.

  Here, when the engagement pin 41 h is separate from the first hinge body 41, an engagement hole is also formed in the first hinge body 41, and the engagement hole of the first hinge body 41 and the first hinge body 42 are formed. It is necessary to insert the engagement pin 41h into the engagement hole 42h after performing the alignment operation for matching the engagement hole 42h. On the other hand, when the first hinge body 41 has the engagement pin 41h, this alignment work can be made unnecessary, so that the engagement pin 41h is separate from the first hinge body 41. The insertion operation of the engaging pin 41h can be performed easily. As a result, the efficiency of the assembly work can be improved.

  Furthermore, the first hinge body 41 and the second hinge body 42 are attached to the back beam 22 and the side beam 32 by fitting the main body portions 41c and 42b into the openings 22c and 32c, respectively. Therefore, since the first hinge body 41 and the second hinge body 42 can be attached to the back beam 22 and the side beam 32 without using a tool or the like, such attachment work can be easily performed.

  Thus, since the main body portions 41c and 42c of the first hinge body 41 and the second hinge body 42 are fitted into the openings 22c and 32c of the back beam 22 and the side beam 32, the resin main body portions 41c and 42c. Is surrounded by the metal peripheral walls of the back beam 22 and the side beam 32. On the other hand, when the back beam 22 and the side beam 32 are fitted in the first hinge body 41 and the second hinge body 42, openings that are surrounded by thin peripheral walls are formed in the resin main bodies 41c and 42c. And since the metal back beam 22 and the side beam 32 are fitted in the opening part, the main-body parts 41c and 42c are easy to be damaged.

  Therefore, when the main body portions 41c and 42c of the first hinge body 41 and the second hinge body 42 are fitted in the openings 22c and 32c of the back beam 22 and the side beam 32, the first hinge body 41 and the second hinge Even if the body 42 is made of resin, it is possible to ensure rigidity at the connecting portion between the first hinge body 41 and the second hinge body 41 and the back beam 22 and the side beams 32. Therefore, the rigidity of the assembled shelf as a whole can be secured and a strong structure can be obtained.

  Further, since the flanges 41 a and 42 a are sandwiched between the end surface of the back beam 22 and the end surface of the side beam 32, the flanges 41 a and 42 a are interposed between the end surface of the back beam 22 and the end surface of the side beam 32. Therefore, even if the side beam 32 is swung with respect to the back beam 22, the flange 41 a that contacts the end surface of the back beam 22 interferes with the flange 42 a that contacts the end surface of the side beam 32. And the end face of the side beam 32 do not interfere with each other. Therefore, it is possible to prevent metal sound from being generated due to interference between the end face of the back beam 22 and the end face of the side beam 32 during the assembly operation.

  With reference to FIG. 6, the assembly process of the assembly-type shelf 1 is demonstrated. 6 (a) is an exploded perspective view of the assembly-type shelf 1, and FIG. 6 (b) is an enlarged exploded perspective view of the protrusion 41g protruding from the support beam 5a and the protrusion 42g protruding from the side beam 32. FIG. 6C is an enlarged perspective view of the hinge body 4 in which a portion indicated by VIc in FIG. 6A is enlarged. The assembly-type shelf 1 is packed in a state where it is disassembled into a back body 2, a side body 3, support beams 5 a and 5 b, and a shelf board 6. By assembling the back body 2, the side body 3, the support beams 5 a and 5 b, and the shelf board 6, the assembly-type shelf 1 is completed.

  As shown in FIG. 6, in order to assemble the assembled shelf 1 in a disassembled state, the back body 2 is first raised. Then, the pair of side bodies 3 are coupled to the back body 2 that has been erected. As described above, the coupling operation is performed by inserting the engagement pin 41h (see FIG. 4B) into the engagement hole 42h (see FIG. 4B). Accordingly, the pair of side surface bodies 3 are slidably and detachably coupled to the back surface body 2 by the hinge body 4. Thereafter, the bolt B (see FIG. 4B) is screwed into the fastening hole 41e. Thereby, since the engaging pin 41h is fixed to the protrusion 42g of the second hinge body 42, it can be prevented from dropping out of the engaging hole 42h.

  Next, the pair of side bodies 3 slidably coupled to the back body 2 are swung so that the pair of side beams 32 are orthogonal to the back beam 22, and then the support beams 5 a are moved to the pair of sides. Coupled to beam 32. Such a coupling operation is performed by inserting the engagement pin 41h (see FIG. 4B) into the engagement hole 42h (see FIG. 4B). After the support beam 5a is coupled to the pair of side beams 32, the shaft portion 44a (see FIG. 4 (b)) of the fastening bolt 44 is screwed into the screwing hole 41h1 (see FIG. 4 (b)). The coupling pin 41h is fixed to the protrusion 42g of the second hinge body 42. Similarly, the support beam 5b is fixed to the pair of support members 34 and the pair of side beams 33 (projections 42g of the second hinge body 42), respectively. Thereafter, the shelf 6 is installed so as to be supported by the back beams 22 and 23, the side beams 32 and 33, the support beams 5a and 5b, and the support plate 24, the support member 34, and the support beam 5b coupled in a frame shape. To do.

  Similar to the back beam 22, the support beams 5 a and 5 b are arranged such that when the main body portion 41 c of the first hinge body 41 is fitted into the openings of the support beams 5 a and 5 b, The protrusion 41g protrudes from the support beams 5a and 5b to the outside. The protrusion 41g is provided with a shaft-like engagement pin 41h. On the other hand, the protrusion 42g protruding outward from the side beams 32 and 33 through the notch is provided on the side of the support beams 5a and 5b. An engagement hole 42h is provided corresponding to the engagement pin 41h. Therefore, the support beams 5a and 5b and the pair of side beams 32 and 33 can be coupled by inserting the engagement pin 41h into the engagement hole 42h.

  Thus, using the first hinge body 41 and the second hinge body 42, not only the pair of side beams 32 and 33 and the back beams 22 and 23, but also the pair of side beams 32 and 33 and the support beams 5a and 5b. Since it can be coupled, the coupling structure of the pair of side beams 32 and 33 and the supporting beams 5a and 5b can be formed in the same structure as the coupling structure of the pair of supporting beams 5a and 5b and the back beams 22 and 23. Can be achieved. Therefore, compared with the case where the pair of side beams 32 and 33 and the support beams 5a and 5b are formed in a different connection structure from the pair of support beams 5a and 5b and the back beams 22 and 23, cost reduction by sharing parts is reduced. You can plan.

  Further, the protrusion 41g that protrudes outside from the support beams 5a and 5b via the notch (not shown) is arranged above the protrusion 42g that protrudes outside from the side beams 32 and 33 via the notch 32d. Therefore, when the engagement pin 41h is inserted into the engagement hole 42h, the protrusion 41g protruding outside from the support beams 5a and 5b is caused by the protrusion 42g protruding outside from the side beams 32 and 33. Supported. Therefore, the support beams 5a and 5b can be supported by the pair of side beams 32 and 33 simply by inserting the engagement pin 41h into the engagement hole 42h.

  The support beams 5a and 5b, the back beams 22 and 23, and the pair of side beams 32 and 33 are respectively provided with flanges 41a and 42a on both end surfaces formed so as to be inclined with respect to the cross section perpendicular to the longitudinal direction. When the flanges 41a and 42a are brought into contact with each other, the support beams 5a and 5b, the pair of side beams 32 and 33, and the back beams 22 and 23 are connected in a frame shape. Therefore, the support beams 5a and 5b, the pair of side beams 32 and 33, and the back beams 22 and 23 receive loads in both directions, a load acting in the longitudinal direction and a load acting in the direction perpendicular to the longitudinal direction. Can be received by the end faces (flanges 41a, 42a). Accordingly, when the support beams 5a and 5b, the pair of side beams 32 and 33, and the back beams 22 and 23 are connected in a frame shape, the strength of the frame-shaped member connected in the frame shape can be improved. 2, even if the pair of side bodies 3 are swingably and detachably coupled by the hinge body 4, the strength of the assembled shelf 1 can be improved.

  Further, when machining the inclined end faces of the back beams 22 and 23, the side beams 32 and 33, and the support beams 5a and 5b, variations occur in processing accuracy, and the inclination angles at the inclined end faces are changed. Even if an error occurs, the tilt angle error can be absorbed by the deformation amount of the flanges 41a and 42a that are in contact with the both end faces. Therefore, even if an error occurs in the inclination angle at both end surfaces when processing both end surfaces of the back beams 22, 23, the side beams 32, 33, and the support beams 5a, 5b, the back beams 22, 23 and the side beams 32 are formed. 33 and the supporting beams 5a and 5b can be firmly connected in a frame shape.

  Since the upper shelf plate 6 is formed with a recess for accommodating the shelf plate 6 on each upper surface of the back beam 22, the pair of side beams 32, and the support beam 5a, the horizontal movement thereof is restricted. Further, the horizontal shelf plate 6 and the lower shelf plate 6 are restricted from moving in the horizontal direction by the main body portion 21 of the back body 2 and the side plate 31 of the side body 3, so that the shelf plate 6 is not displaced. It has become.

  For example, in the above-described embodiment, the engaging pin 41h is protruded from the protruding portion 41g of the first hinge body 41. However, the present invention is not limited to this, and the engaging pin 41h is engaged from the protruding portion 42g of the second hinge body 42. The pin 41h may be protruded. Further, the engaging pin 41h may be configured separately from the protrusion 41g of the first hinge body 41 and the protrusion 42g of the second hinge body 42. In this case, the length of the engaging pin 41h is formed longer than the plate thickness of the protruding portion 41g of the first hinge body 41 and the protruding portion 42g of the second hinge body 42, and the protruding portions 41g and 42g are respectively provided with engaging holes 42h. To penetrate. If the nut is screwed into the upper end and the lower end of the engagement pin 41h inserted into the engagement hole 42h, the engagement pin 41h can be prevented from dropping without using the fastening bolt 44. Therefore, the fastening bolt 44 can be omitted.

  In the above embodiment, the engagement pin 41h is formed of a shaft-shaped member. However, the present invention is not limited to this. For example, the engagement pin 41h is a protrusion having a semicircular cross-section including its axis. May be formed. In such a case, the operation of inserting the engagement pin 41h into the engagement hole 42h can be easily performed.

  Furthermore, in the said embodiment, although flange 41a, 42a was formed in the 1st hinge body 41 and the 2nd hinge body 42, respectively, it is not necessarily restricted to this, The 1st hinge body 41 and the 2nd hinge body 42 The structure which forms the flanges 41a and 42a in any one of these may be sufficient. Even in such a case, when the support beams 5a and 5b, the pair of side beams 32 and 33, and the back beams 22 and 23 are connected in a frame shape, the flange 41a (or the flange 42a) is interposed between the opposing end surfaces. Since it is provided, it is possible to prevent the generation of metal sound during assembly. In addition, since either one of the flanges 41a and 42a of the first hinge body 41 and the second hinge body 42 can be omitted, the light weight of the first hinge body 41 (or the second hinge body 42) from which the flanges 41a and 42a are omitted. Can be achieved. Thus, cost reduction can be achieved.

  In the above embodiment, the first hinge body 41 is attached to the back beams 22 and 23 and the support beams 5a and 5b, and the second hinge body 42 is attached to the pair of side beams 32 and 33. Although described above, the present invention is not necessarily limited to this. The first hinge body 41 is attached to the pair of side beams 32 and 33, and the second hinge body 42 is attached to the back beams 22 and 23 and the support beams 5a and 5b. The structure to wear may be sufficient. Alternatively, the first hinge body 41 may be attached to one end of the pair of side beams 32 and 33 and the second hinge body 42 may be attached to the other end. In this case, since different hinge bodies are attached to both ends of the pair of side beams 32 and 33, one end connected to the back beams 22 and 23 of the pair of side beams 32 and 33, and a pair of sides. Since the other ends connected to the support beams 5a and 5b of the beams 32 and 33 can be distinguished, the efficiency of the assembly work can be improved.
