DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a horizontal member, which is particularly effective when a beam is mounted between side supports forming a rack or a desk.

[0002]

2. Description of the Related Art For example, a server rack is constructed by connecting a pair of left and right side supports by beams, and laying a top plate, a shelf, and the like on the side supports. The beams, of course, play a role in enhancing the independence of the rack, but they also often serve as attachment parts for optional members such as intermediate shelves and wiring ducts. For or to secure visibility,
There are cases where the mounting position of the beam can be changed with respect to the side support in the assembled state.

Conventionally, as such a beam mounting structure,
The length of the beam is set to a size that approximately matches the inner dimension of the pair of side supports, and brackets are fixed at both ends of the beam, and this bracket is screwed to the inner surface of the side support. It is customary to keep the garment on.

[0004]

However, in this case, when the beam is inserted into and removed from the side support, the end face of the beam and the inner surface of the side support rub against each other, so that a damage is caused on those portions. It is easy to cause inconvenience that the beam is inclined during operation and bites between the side support members so that it cannot be pulled out.
When the beam is slightly shortened, the bracket is in close contact with the inner surface of the side support after all, so that the situation is completely the same, and the strength tends to be reduced. In addition, if the brackets are screwed one by one, when the mounting position is changed, screw holes are opened at a number of places on the side support, making it difficult to see, and the work of changing the mounting position is not easy.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a method of mounting a beam or other horizontal member via a pair of brackets between mounting surfaces. An object of the present invention is to provide a mounting structure for a horizontal member that allows the horizontal member to be mounted without rubbing against the side support member, and that can be easily changed in a mounting position without impairing the mounting strength and appearance. It is.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS For this purpose, the present invention relates to a method of constructing a horizontal member via a pair of brackets between a pair of mounting surfaces each having a hook hole at an opposing position. First having an engageable engaging claw
And a restricting part which is associated with the first bracket element so as to be relatively movable with respect to the first bracket element, and which is provided in a part thereof by a relative movement thereof, is inserted into a hook hole to engage the first bracket element together with the restricting part. A second bracket element for irremovably anchoring the dovetail to the hook hole, and the engaging claw and the restricting part being moored to the hook hole from a position where the engaging claw and the restricting part can be inserted into and removed from the hook hole. And a biasing means for biasing the bracket to a position where the horizontal member can be mounted.

[0007] With this configuration, the bracket can be easily attached to and detached from the hook hole of the mounting surface without attaching the horizontal member, and the length of the horizontal member is set between the mounting surfaces. By making it slightly shorter than the inner dimension, it can be mounted on the bracket without interfering with the mounting surface. Moreover, in the present invention, since the bracket is moored in the hook hole, the appearance of the mounting surface is not impaired by changing the mounting position, and the bracket cannot be removed in the mooring state. By attaching the horizontal member to the vehicle, an appropriate mounting state of the horizontal member can be ensured.

In order to effectively increase the mounting strength, the restricting portion of the second bracket element is an engaging claw that can be engaged with the hook hole in a direction opposite to the engaging claw of the first bracket element. The biasing means preferably biases both bracket elements from a position where each engaging claw can be simultaneously inserted into and removed from the hook hole toward a position where each engaging claw can be simultaneously engaged with the hook hole. .

[0009] In order to make the mounting of the transverse member simple, it is necessary to temporarily hold the transverse member to the bracket and to fix the transverse member to the bracket at the same time when biasing is performed by the biasing means. desirable. As a simple urging means, a screw member that penetrates the horizontal member and is screwed to the second bracket element is used, and the horizontal member is attached to the scaffold by the screwing operation of the screw member. Is preferably moved relative to the first bracket element.

[0010] In order to effectively improve the handling convenience, between the first bracket element and the second bracket element,
It is preferable to provide an engagement portion for restricting the relative movement operation to a certain range. As a specific embodiment of the engaging portion, a hole provided in one of the first bracket element and the second bracket element and a shaft portion provided in the other and movably inserted into the hole are provided. Can be cited.

[0011] The location of the engagement portion is limited to one location,
In order to realize a smooth relative movement operation of both brackets and simplification of the operation, the first bracket element and the second bracket element are pivotally connected via a support shaft, and the first bracket element and the first bracket element are connected to each other. Through the pivotal movement of the second bracket element about the support shaft, a position where the engaging claw and the restricting portion can be simultaneously inserted into the hook hole and the engaging claw and the restricting portion can be simultaneously anchored in the hook hole in both bracket elements. Preferably, the position is determined.

In order to allow the horizontal member to be easily retrofitted to the bracket, the first bracket element has a second bracket element between a pair of opposing walls, and both of them are provided. Conveniently, it is configured so that the cross member can be attached to a position covering the first bracket element while the bracket element is anchored in the hook hole.

[0013] In order to attach the horizontal member to the bracket securely without any backlash by a simple operation, a shaft portion is provided on one of the opposing wall of the first bracket element or the corresponding portion of the horizontal member. While protruding, the other side is provided with a daruma hole into which the shaft part can be inserted, and after the urging by the urging means,
It is preferable that the shaft portion is held at a position where it is shifted from the large diameter portion to the small diameter portion of the daruma hole.

As a preferred application example of the present invention, there is a case where the mounting surface is the inner surface of a side support constituting a rack or a desk, and the horizontal member is a beam connecting the two side supports. No. In addition to the above, the present invention provides a method of erection of a horizontal member via a bracket between a pair of mounting members arranged at opposing positions, a pair of orthogonally facing opposing surfaces of the mounting members facing in the same direction. Hook holes are provided on the mounting surfaces of the brackets, hook holes are provided in the horizontal member so as to correspond to the hook holes, and the bracket is provided with an engaging claw that can be simultaneously engaged with both hook holes, Fixing means for holding the claws in engagement with the hook holes and fixing the bracket at the positions, and at a position where the hook holes on the mounting surface and the hook holes on the horizontal member are aligned. The horizontal member may be attached to the attachment surface by the bracket.

With this configuration, the bracket can be easily attached to and detached from the hook holes of both the horizontal member and the mounting surface, with the horizontal member sandwiched between the mounting surface and the mounting hole. . In addition, the length of the horizontal member can be made slightly longer than the inner dimension between the opposed surfaces, and the horizontal member can effectively secure a mounting allowance for the column and increase its mounting strength. . In addition, since there is no gap between the column and the beam, the appearance in a forward view is also improved. Furthermore, even if the cross member is longer than the distance between the opposing surfaces, it can be attached to the mounting surface via the bracket without interfering with the opposing surface, and the end surface of the cross member rubs against the opposing surface Therefore, there is no possibility that those parts are damaged or that the horizontal member is inclined and bites between the opposing surfaces and cannot be removed. Further, since the bracket is engaged with both the hooks on the horizontal member and the mounting surface, the appearance of the mounting surface is not impaired even if the mounting position is changed, and the bracket is fastened in the engaged state. Since the bracket cannot be removed, the horizontal member can be maintained in an appropriate mounting state.

In order to easily increase the degree of adhesion between the mounting surface of the bracket and the horizontal member, the bracket is inserted into the hook hole first with the engaging claw, and the entire bracket is rotated. It is preferable to attach it. In order to realize a proper mounting state between the engaging claw and the hook hole, and to be able to securely mount the bracket, the engaging claw is engaged with the mounting surface and the hook hole of the horizontal member. The distance between the rear surface of the engaging claw that abuts on the back side of the mounting surface and the first abutment side of the bracket that abuts the horizontal member is determined by the thickness of the hook hole of the mounting surface and the hook hole of the horizontal member. It is desirable to make it approximately equal to

Further, in order to prevent the horizontal member from moving with respect to the mounting member with the bracket mounted,
It is effective that the engaging direction between the engaging claw and the hook hole is in a mutually converging direction or in an opposing direction at both ends of the horizontal member. In order to effectively improve the mounting strength, the fixing means is a screw member that penetrates the horizontal member and is screwed to the horizontal member, and the screw member using the bracket as a scaffold is screwed into the bracket. Is preferably fixed to the horizontal member, and the horizontal member is fixed to the mounting surface.

In order to allow the engaging claws of the bracket to more securely engage with the engaging holes of the mounting surface without rattling, the hook holes of the mounting surface have an opening width toward the end thereof. It is preferable to have a shape that gradually narrows.
In order to make the mounting work of the transverse member and the bracket easier, provision is made on the transverse member for temporary holding means for temporarily holding the transverse member on the mounting surface, and the transverse member is attached by the temporary holding means. It is preferable that the bracket be inserted into both the hook holes while being temporarily held on the surface. As a specific embodiment of such a temporary holding means, there can be mentioned a projection provided on the horizontal member so as to project toward the mounting surface and to be inserted into and removed from the hook hole of the mounting surface.

Further, in order to provide the projection more easily, the horizontal member is formed by retroactively deforming a sheet metal material, and the projection faces a part of the horizontal member toward the mounting surface. It is preferably formed by cutting and raising. In particular, such projections, when opening a rectangular hook hole in the transverse material,
Cut out three sides of the side that is the periphery of the hook hole and leave the remaining 1
It can also be formed simultaneously with the hook hole by cutting and raising it along the side toward the mounting surface. By doing so, this projection and the engaging claw of the bracket
The projection can serve as a temporary holding means, and can also serve as a permanent stop with respect to the mounting surface together with the engaging claw.

In such a case, in order to more effectively prevent rattling in the vertical direction of the horizontal member attached to the mounting surface, the upper edge or the upper edge of the hook hole on the mounting surface must be provided. It is advantageous to form a hook hole extension on at least one of the lower edges to widen the opening of the hook hole and to accommodate the projection in this hook hole extension. As a preferred application example of the present invention as described above, the mounting member is a side support that constitutes a rack or a desk, the mounting surface is a rearward facing surface of the side support, and the horizontal member is A beam that connects the support members on both sides may be used.

In this case, in order to effectively utilize the structure of the horizontal member so that the side support can be made independent and to simplify the work of assembling a rack or a desk, the horizontal member is required. Are mounted on the mounting surface so as to be arranged in two rows in the upper and lower directions, and both ends of both horizontal members are connected with vertical frame members, respectively, and the side support members are made to stand by the horizontal members and vertical frame members. It is desirable to form a frame. In particular, in order to effectively increase the strength of a rack, a desk, or the like, and to easily attach a top plate, a shelf, or the like, it is preferable to attach both the beam and the frame to the side support.

The beam 110 is provided with a temporary holding means K for temporarily holding the beam 110 at a predetermined position when the upright wall 111 is mounted on the mounting surface 122c in contact with the mounting wall 122c.
To be more specific, the temporary holding means K is similar to that shown in FIGS.
As shown in FIG. 18, two hook holes 112 are provided immediately above and below the upper and lower hook holes 112, respectively. First, the upper temporary holding means K opens a part of the upper end of the upright wall 111, and opens the upper end 115 a of the crank-shaped projection 115 bent forward and upward toward the mounting surface 122 c at the opening. It is inserted and the lower end 115b side is attached to the rear surface of the upright wall 111 by appropriate means such as welding. On the other hand, the temporary holding means K on the lower side is
11 is a tongue-shaped projection 116 which is formed by cutting a part of the lower end of the sheet 11 substantially horizontally toward the mounting surface 122C. Thus, these upper and lower projections 115 and 116 are connected to the hook holes 12 of the mounting surface 122C corresponding to the hook holes 112 of the beam 110.

The distance between the hook holes 112 and the hook holes 112 on the side closer to them substantially corresponds to the pitch of the hook holes 125 on the mounting surface 122C.

As shown in FIGS. 12, 13 and 15, the frame 100 has a structure substantially the same as that of the beam 110 and is arranged as a horizontal frame member 100A in two upper and lower stages with a predetermined distance therebetween. The left and right side ends of the horizontal frame member 100A are integrally connected by a vertical frame member 100B obtained by retroactively deforming a sheet metal material. The difference from the beam 110 in the configuration of the horizontal frame member 100A is that the upper and lower temporary holding means K are provided only at the upper end of the upper horizontal frame member 100A and at the lower end of the lower horizontal frame member 100A. It is. These upper and lower temporary holding means K
Is a projection 100a formed in the same manner as the projection 116 serving as the temporary holding means K on the lower side of the beam. The other configuration of the frame 100 is the same as that of the beam 110, and thus the description is omitted.

The bracket 180 is shown in FIGS.
As shown in FIG. 19, the sheet metal material is subjected to retroactive deformation processing, and a pair of upper and lower horizontal walls 182 facing the pitch of the hook holes 112 of the beam 110 at substantially equal intervals, and these horizontal walls 182.
And an upright wall 181 which is continuous at the rear end side. At the front end side of the horizontal wall 182, an engaging claw 183 protruding forward and sideward is formed on the outer end side, and the engaging claw 183 is located inward of the engaging claw 183 in the front-rear direction over the inner end. A first contact side 182a and a second contact side 182b are formed in a step shape. The first and second abutment sides 182a and 182b are provided when the engaging claw 183 is simultaneously engaged with the beam 110 and the hook holes 112 and 125 of the mounting surface 122C, respectively. It comes into contact with the mounting piece 113 from behind. At this time, the nut 1 is attached to the upright wall 181 of the bracket 180.
14 and a through hole 181 a corresponding to the screw insertion hole of the nut mounting piece 113.
a, a screw member 184 serving as fixing means is inserted and screwed into the screw insertion hole 113a and the nut 114, and
The zero engaging claw 183 is biased from a position where it can be inserted into and withdrawn from the hook holes 112 and 125 to a position where it can be anchored.

The procedure for attaching the beam 110 and the frame body 100 is performed as follows. However,
As described above, the horizontal frame material 100A constituting the frame 100
Has substantially the same configuration as the beam 110, so only the method of mounting the beam 110 will be described here in detail.
As shown in FIG. 12, first, the beam 110 is inserted into the wiring space 171 from the opening 126 provided at the back of the column. Then, the upper end side of the beam 110 is slightly inclined forward, and the upper protrusion 115 is inserted into the hook hole 125 of the mounting surface 122C,
By rotating the lower end side forward with the projection 115 as a fulcrum,
By inserting the lower protrusion 116 into the hook hole 125 of the corresponding mounting surface 122C, the beam 110 is attached to the mounting surface 122C.
C is temporarily held. At this time, the upper and lower hook holes 112 of the beam 110 correspond to the corresponding hook holes 125 of the mounting surface 122C.
, Respectively. In that state,
As shown by the imaginary line in FIG. 19, the outer end side of the bracket 180 is tilted forward, and the engaging claw 183 is moved from the rear opening side of the beam 110 to the hook hole 112 of the beam 110 and the mounting surface 122C.
Of the beam 1 and the hook hole 125 of the
Rotate the inner end side forward to a position substantially parallel to 10,
The outward faces 183a of the engagement claws 183 are
5 is in contact with the opening side edges 112a and 125a. Also, the distance m between the rearward face 183b of the engaging claw and the first contact side 182a is set to be substantially equal to the thickness of the support and the horizontal member provided with the mounting surface 122C. It will be closely attached to the attachment surface 122C and the beam 110. Further, engaging claws 183 are provided at both ends of the beam 110.
Are engaged with the hook holes 112 and 125 in directions opposite to each other, and in this state, the beam 110 is
2 so as not to move. Then, the screw member 184 is inserted into the through hole 181a of the bracket 180 and the screw insertion hole 113a of the beam 110 located at the corresponding position, and is screwed to the nut 114 so that the bracket 180
The upright wall 181 is fastened to the scaffold. This screw member 18
As shown in FIGS. 17 to 19, the tightening operation of No. 4 pulls the engaging claw 183 rearward while the rear surface 183 b of the engaging claw 183 is in contact with the back side of the mounting surface 122 </ b> C.
The first and second abutment sides 182a, 182b of the horizontal wall 182 of the bracket 180 correspond to the upright wall 11 of the beam 110, respectively.
1 and the nut mounting piece 113 are pressed against the rear from behind. That is, by the tightening operation of the screw member 184 using the standing wall 111 of the bracket 180 as a scaffold, the engagement state of the bracket 180 with the hook holes 112 and 125 is appropriately maintained, and the bracket 180 is
0 and the mounting surface 122C, so that a close mounting state of the standing wall 111 of the beam 110 to the mounting surface 122C is also realized. When the mounting position is changed, the above procedure is reversed, and the beam 110 is once removed from the mounting surface 122C, and the wiring space 1 is removed.
It is only necessary to raise and lower the inside of 71 and attach it to the attachment surface 122C again in a desired height position by the same procedure as described above.

On the other hand, since the projections 100a as the temporary holding means K on the upper and lower sides of the frame 100 project substantially horizontally toward the mounting surface 122C, the frame 100 is
Are temporarily held on the mounting surface 122C in a state where the entire frame 100 is erected substantially vertically so that the frame 100 is inserted substantially horizontally into the hook hole 125 of the corresponding mounting surface 122C.
It is mounted on the mounting surface 122C by the bracket 180 in the same manner as the beam 110. Since the frame body 100 does not require much change in height or the like unlike the beam 110, the beam 110 and the shelf 1 together with the left and right columns 122 are provided.
Before assembling 40 etc., they are assembled.

As described above, the beam 11 according to this embodiment is
The mounting structure of No. 0 includes a pair of side surfaces 120A of a pair of side supports 120, which are mounting members at opposing positions.
The bracket 110 is used to mount the beam 110 between the mounting surfaces 122C, each of which has a hook hole 125 and faces rearward at right angles to
When the beam is erected, a hook hole 112 corresponding to the hook hole 125 of the mounting surface 122C is provided in the beam 110, and the bracket 180 simultaneously engages with the hook hole 122 of the beam 110 and the corresponding hook hole 125 of the mounting surface 122C. Engagement claw 183 that can be
25, and the bracket 180 is attached to the beam 11.
The fixing member 110 is provided with a screw member 184 as fixing means for fixing the beam 110 to the mounting surface 122C using the bracket 180.
It is intended to be attached to.

According to such a configuration, the bracket 18
0 is the beam 110 and the hook holes 112, 12 in the mounting surface 122C.
5 can be easily attached and detached.
Since the longitudinal dimension can be set slightly longer than the inner dimension between the opposed surfaces 122A, it is possible to effectively secure an allowance for attachment to the column 122 and increase the attachment strength. Further, the columns 122 can be connected to each other without gaps by the beams 110, and the appearance from the front can also be improved. In particular, since such a beam 110 is attached not to the opposing surface 122A of the column 122 but to a rearward surface orthogonal to the opposing surface 122A and does not need to be screwed to the opposing surface 122A, the appearance is also reduced in this respect. Can be improved. Further, according to such a mounting structure, the beam 110 is not interfered with the opposing surface 122A, and
Since the beam 110 can be attached to the 2C, it is possible to effectively avoid the inconvenience that the portion of the opposing surface 122A or the like that is easily seen from the outside is damaged due to the fact that the beam 110 rubs or bites against the opposing surface 122A and cannot be removed. . Also, the support 12 with the beam 110 assembled in advance is provided.
2 can be retrofitted, so that attachment / detachment of the beam 110 and change of the height position are very easy. Therefore, it is possible to realize a proper mounting state of the beam 110.

Further, the bracket 180 is attached to the engaging claw 183.
From the hook holes 112 and 125,
Since the entire bracket 180 is pivotally mounted on the base end of the bracket 180 as a fulcrum, the bracket 18 can be disengaged as compared with the case where the bracket is slid and the engaging claw is engaged with the hook hole.
Thus, the degree of adhesion between the zero and the beam 110 and the mounting surface 122C can be easily improved, and the mounting of the bracket 180 is also easy.

Further, the distance m between the rearward face 183b of the engaging claw and the first contact side 182a is set to be substantially equal to the thickness of the upright wall 111 of the support column 122 and the beam 110.
The beam 110 can be securely attached to the front and back without play. Further, the engaging claws 183 are connected to the hook holes 112 and 12.
5, the beams 110 are engaged in opposite directions at both ends, so that the beam 110 is securely held so as not to move from the position with respect to the column 122 with the bracket 183 mounted. Can be.

Further, the fixing means is a screw member 184,
By the screwing operation of the screw member 184, the bracket 18 is
0 is fixed to the beam 110, and the beam 110 is attached to the mounting surface 1 at the same time.
Since the fixing is performed at 22C, the mounting strength of the beam 110 can be appropriately and easily increased. Further, the beam 110 is supported by the temporary holding means K provided on the beam 110.
2 and the bracket 180 is mounted in this state, so that it is not necessary to perform the operation while supporting the beam 110 with a hand or the like, and the operation can be simplified. In this state, the beam 1 is temporarily held and the beam 1 is temporarily held.
10 hook holes 112 and corresponding mounting surfaces 122C
The hook claw 183 of the bracket 180 can be very easily inserted into the hook holes 112 and 125.

In particular, as the temporary holding means K, projections 115 and 116 projecting toward the mounting surface 122C are provided at the upper end and lower end of the beam 110, and these projections 115 and 116 are attached to the mounting surface 122C. It is not necessary to build a special structure for temporarily holding the beam 110 into the column, and the hook hole 125 for inserting and removing the engaging claw 183 can be inserted into and removed from the hook hole 125. Can also be used effectively during temporary holding. At that time, beam 1
Reference numeral 10 denotes a material obtained by retroactively deforming a sheet metal material, and a part of the material is cut and raised to produce the lower protrusion 116.
Such an engagement means K can be easily formed.

In the present embodiment, the mounting structure of the beam 110 as described above is applied to the column 122 as a mounting member constituting the side support 120 of the server rack, and the rear surface of the column 122 is used as the mounting surface 122C. Because of this, the support 122 can be provided with independence, and the beam 110 can be provided with a shelf 140.
And the like, and the rack 14 can be easily changed in height.
0 may be provided.

Further, such a beam 110 is connected to the horizontal frame member 10.
0A are arranged vertically in two stages, and both ends of the vertical frame material 100
Since the frame 100 connected by B is configured, such a frame 100 is attached to the mounting surface 122C of the column 122 by effectively utilizing the easy and reliable mounting structure of the beam 110 as described above. Thereby, the independence of the column 122 and the strength of the rack can be further increased. In addition, since both the beam 110 and the frame 100 are attached to the column 122 to which the present embodiment is applied in a similar structure,
It is possible to configure a very useful rack in which the strength of the rack can be more effectively increased and the top plate 130, the shelf 140, and the like can be easily attached.

The present invention is not limited to the second embodiment. For example, as shown in FIG. 20A, the engaging claw forms a portion that also protrudes inward of the engaging claw 283, and has a rearward facing surface 283c and a rearward facing surface 2 that protrudes outward.
83b is brought into contact with the back side of the mounting surface 122C, and the inward surface 283d is brought into contact with the opening side edges of the hook holes 112 and 125, so that the stronger engagement claws 283 are provided.
Can be obtained. Also, the mounting surface 122c
The hook hole is not limited to a rectangular hole, and may have a tapered shape such that an opening width gradually narrows toward an end as shown in FIG. By doing so, the engaging claw of the bracket can be more reliably engaged with the tapered opening edge 325b of the hook hole 325 by restricting the play thereof in the vertical direction, and the beam can be moved in the vertical direction. It can be attached more securely without sticking.
Here, for convenience in forming the hook hole 325,
The opening edge 325b is opened in a tapered shape toward both end portions, but the hook hole 325 is formed substantially in the center so that the opening edge has a tapered shape only in the direction in which the left and right engagement claws are respectively engaged. As shown by the imaginary line, a shape that is vertically divided in half or a shape similar thereto may be provided on each of the left and right sides. Further, as shown in FIG. 20C, even if the hook hole 425 has a horizontally long elliptical shape, its opening edge 4
Since 25b gradually narrows toward the end, the same effect as the hook hole 325 having the tapered shape can be obtained.

When a rectangular hook hole 515 is opened in a beam or the like, as shown in FIG.
15 are cut out of the sides which are the peripheral edges of 15 and the remaining one side 51
When the projection 515 formed at the same time as the hook hole 512 by being cut and raised toward the mounting surface 122c side along 2b is used as the temporary holding means K, the projection 515 and the engaging claw of the bracket 180 are used. 183 can be inserted into a common hook hole 525 of the mounting surface 122c, and the projection 515 plays a role as a temporary holding means K, and also serves as a final stop for the mounting surface 122c together with the engaging claw 183. Will fulfill. here,
Although the case where the upper edge 512b of the hook hole 512 is cut and raised to form the upper protrusion 515 is described, the lower protrusion 516 is formed.

The hook hole expansion portion 525c that expands the opening of the hook hole 525 into a substantially rectangular shape is formed, and a tapered shape that gradually narrows toward both ends of the hook hole 525 is formed. When the projection 515 is accommodated and the engaging claw 183 is engaged with the tapered opening edge 525b, it is possible to more effectively prevent the beam from rattling in the vertical direction.

Further, the present invention is not limited to the columns of the rack,
The present invention can be applied to various things having a pair of attachment members such as a desk. In addition, the specific configuration of each part,
The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0063]

Since the present invention has the above-described structure, the following effects can be obtained. That is, in the mounting structure of the transverse member according to the present invention, the bracket is constituted by the first bracket element having the engaging claw and the second bracket element having the restricting portion, and the two bracket elements are biased by the urging means. And a position that can be simultaneously inserted into and removed from the hook hole at the same time, and a position that can be anchored in the hook hole.

For this reason, it is possible to easily perform the work of engaging and disengaging the bracket with respect to the hook hole while ensuring the function of properly attaching the horizontal member to the mounting surface, and furthermore, when attaching or detaching the horizontal member, the mounting surface or the like is required. It is possible to maintain the mounting surface and the furniture in a proper appearance for a long period of time without damaging the furniture or opening screw holes in many places. In particular, when the restricting portion of the second bracket element is an engaging claw that engages with the hook hole in a direction opposite to the engaging claw of the first bracket element, the bracket itself is firmly fixed to the mounting surface. Therefore, the mounting strength of the horizontal member mounted via the bracket can be effectively improved.

Further, by temporarily holding the horizontal member to the bracket and simultaneously fixing the horizontal member to the bracket at the time of urging by the urging means, the labor can be minimized and the horizontal member can be set at the predetermined mounting position. Can be attached. If the urging means is a screw member and the two bracket elements are relatively moved through the screwing operation of the screw member, the structure can be simplified and the mounting operation can be simplified. It can be reliably held at the destination position.

Further, if an engaging portion for restricting the relative movement of the bracket element within a certain range is formed between the two bracket elements, it is possible to integrally handle the bracket element and to remove the bracket which is detached from the hook hole. By maintaining the state in which it can be inserted again into the hook hole as it is, it is possible to effectively improve the convenience of handling, and if the engaging portion is formed as an engaging structure of a shaft portion and a hole which can move relatively, it is simple. Structure.

In providing such an engaging portion, the first and second bracket elements are pivotally connected via a support shaft, and the state of engagement with and disengagement from the hook hole is switched through the turning operation. By doing so, the formation of the engagement portion can be suppressed to one place, the operation can be facilitated, and the operation of the screw member or the like can be performed in one place. Further, the second bracket element is provided between the opposing walls of the first bracket element, and the horizontal member is attached to a position covering the first bracket element in a state where both bracket elements are inserted through the hook holes. With this configuration, it is possible to easily and surely attach the horizontal member to the bracket.

Further, when the horizontal member is covered with the first bracket element, the shaft provided on one side is shifted from the large diameter part of the daruma hole provided on the other side to the small diameter part. Can easily and reliably position the horizontal member at a predetermined position of the bracket. Since the present invention has the above-described mounting structure, even when the application object is a side support body of a server rack or the like where high independence is required, it is possible to easily and appropriately change the mounting position of the horizontal member. It can be made possible.

The mounting structure for a horizontal member according to the present invention also corresponds to hook holes provided on a pair of mounting surfaces which are orthogonal to the opposing surfaces of the pair of opposing mounting members and face in the same direction. A hook hole is provided in the horizontal member so that the hooks can be engaged simultaneously with the hook holes in a state where the hook holes are aligned with each other, and the engaging claws are engaged with the hook holes by the fixing means. The bracket is fixed to the horizontal member so as to maintain the engaged state, and the horizontal member is provided between the mounting members.

For this reason, the bracket can be easily disengaged from the hook holes of both the horizontal member and the mounting surface, while ensuring the proper mounting function of the horizontal member to the mounting surface.
In addition, it is possible to effectively secure an allowance for attachment to the attachment member and increase the attachment strength of the horizontal member, and to improve the appearance in a front view without creating a gap between the column and the beam. it can. Furthermore, since the horizontal member is attached to the mounting surface orthogonal to the opposing surface, there is no risk of damaging the opposing surface and exposing many screw holes, and the appropriate appearance of the opposing surface and furniture is maintained for a long time It is also possible to do.

When the bracket is mounted by rotating the bracket and inserting the engaging claw into the hook hole, the base end of the engaging claw is engaged with the opening edge of the hook hole. If the bracket is pivoted about that position, not only the mounting of the bracket is facilitated, but also a more closely mounted state of the bracket can be obtained. Further, the distance between the rear surface of the engaging claw abutting on the back side of the mounting surface and the first abutting side of the bracket abutting on the horizontal member is substantially equal to the thickness of both hook holes into which the engaging claw is inserted. If they are made equal, the mounting member provided with the mounting surface and the horizontal member can be tightly sandwiched between the rearward surface of the engaging claw and the first contact side, so that it can be more closely and appropriately. By engaging the engaging claws, the horizontal member can also be appropriately mounted on the mounting surface.

Further, when the engaging claws are engaged with the hook holes in mutually opposite or opposite directions at both ends of the horizontal member, the engaging claws are engaged. In this state, the horizontal member cannot move with respect to the mounting surface, so that the horizontal member can be properly held at that position. When the fixing means is a screw member and the bracket is fixed to the cross member by the screwing operation and the cross member is fixed to the mounting surface at the same time, the mounting strength is effectively improved with a simple structure. However, it is possible to realize an appropriate attachment state of the horizontal member.

Further, when the hook hole of the mounting surface is opened so that the opening width gradually narrows toward the end, the engaging claw of the bracket is more strongly engaged with the hook hole. Since the play of the engaging claw in the vertical direction is restricted, the horizontal member can be more appropriately attached without rattling. Further, if the transverse member is temporarily held on the mounting surface by the temporary holding means provided on the transverse member, and in this state, the bracket is mounted so that the hook holes of the transverse member and the mounting surface coincide with each other. Therefore, it is possible to reduce the convenience of the work of attaching the horizontal member. In this case, if such a temporary holding means is a projection provided on the horizontal member so as to protrude toward the mounting surface and can be inserted into and removed from a hook hole of the mounting surface, the structure for temporary holding is separately provided on the mounting member. There is no need to build it, and the hook hole on the mounting surface can be used for both temporary holding and permanent fastening.

Further, when a projection obtained by cutting and raising a part of a horizontal member made of a sheet metal material is used as a temporary holding means, such a projection can be produced very easily. In particular, in this case, when the hook hole is opened in the horizontal member, if one side of the opening edge is cut and raised, such a projection can be more easily manufactured. Further, with this configuration, the projection and the engaging claw can be inserted into the common hook hole of the mounting surface, so that the projection functions as the temporary holding means, and the hook and the engaging claw can be inserted into the mounting surface. It can also function as a stop.

At this time, a hook hole extension for expanding the opening of the hook hole is formed on at least one of the upper edge and the lower edge of the hook hole on the mounting surface, and the temporary holding means is provided on the hook hole extension. If the barrel projection is accommodated, the projection is retracted to the hook hole expanding portion and engaged with the peripheral edge thereof, and the engaging claw is engaged with the opening side edge of the hook hole,
By obtaining a stronger engagement state, it is possible to extremely effectively prevent rattling of the horizontal member in the vertical direction.

In the case of the present invention having the above-described structure, if the object to be applied is a side support constituting a rack or a desk, it is possible to appropriately change the mounting position of a beam as a horizontal member. In particular, in the case where a frame member in which the horizontal members are arranged in two rows vertically and both ends thereof are connected by a vertical frame member is mounted on the mounting surface, the simple and proper mounting of the horizontal members as described above. By making effective use of the structure, it is possible to further improve the independence of the side support. Furthermore, if both the beam and the frame are attached to the side support, the work of assembling a rack or a desk can be simplified, and the position of the beam can be easily changed after the assembly. Instead, it is also possible to easily attach a top plate, a shelf, or the like using a beam or a frame.
