BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal member mounting structure that is particularly effective when a beam is mounted between side support members that form 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 support members with a beam, and installing a top plate and a shelf plate on the side support members. Of course, the beam plays a role of increasing the independence of the rack, but in addition, it often serves as a mounting part for optional members such as intermediate shelves and wiring ducts. In order to secure visibility
In some cases, the mounting position of the beam can be changed with respect to the assembled side support.

Conventionally, as such a beam mounting structure,
Set the length of the beam to a size that approximately matches the inner size of the pair of side supports, fix the brackets at both ends of the beam, and screw the bracket to the inner surface of the side support. It is customary to keep them fixed by.

[0004]

However, in this way, when the beam is inserted into and removed from the side supports, the end surface of the beam and the inner surface of the side support rub against each other and scratches are formed on those parts. It is apt to cause inconvenience that the beam is tilted during operation and is caught between the side support members so that the beam cannot be inserted or removed.
When the beam is made slightly shorter, the situation is exactly the same because the bracket comes into close contact with the inner surface of the side support body in the end. Moreover, if the brackets are screwed one by one, when the mounting position is changed, the screw holes are opened at a large number of places on the side support member, which is unsightly, and the work for changing the mounting position is also difficult.

[0005]

In addition, the horizontal dimension of the horizontal member can be made slightly longer than the inner dimension between the facing surfaces, and the horizontal mounting member can effectively secure a mounting allowance for the column and increase its mounting strength. . Further, since there is no gap between the support column and the beam, the appearance in the front view is also improved. Further, even if the horizontal member is longer than the distance between the facing surfaces in this way, it can be attached to the mounting surface via the bracket without interfering with the facing surface, and the end surface of the horizontal member rubs against the facing surface. Therefore, there is no possibility that those parts will be damaged or that the horizontal member will be tilted and will be caught between the facing surfaces and that insertion / removal will be impossible. Furthermore, since the bracket engages with the opening edges of the hook holes on both 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 fixed in the engaged state. By doing so, the bracket cannot be pulled out, so that the horizontal member can be maintained in an appropriate attached state. Further, since the bracket is inserted into the hook hole first from the engaging claw and the bracket is rotated and mounted with the base end of the engaging claw as a fulcrum, the bracket mounting surface and the horizontal member are The adhesion to can be easily increased.

It is preferably formed by raising. In particular, such a protrusion cuts out three of the sides serving as the opening edge of the hook hole when the rectangular hook hole is opened in the horizontal member,
It may be formed at the same time as the hook hole by cutting and raising along the remaining one side toward the mounting surface.
By doing so, this protrusion and the engaging claw of the bracket can be inserted into the common hook hole of the mounting surface, and the protrusion can serve as a temporary holding means and can also work together with the engaging claw. It is possible to add a role as a final stop to the mounting surface.

In such a case, in order to more effectively prevent rattling of the horizontal member mounted on the mounting surface in the vertical direction, in order to more effectively prevent rattling in the vertical direction, at the opening edge of the hook hole on the mounting surface, the upper edge thereof is formed. Alternatively, it is convenient to form a hook hole expanding portion that expands the opening of the hook hole on at least one of the lower edges, and accommodate the protrusion in the hook hole expanding portion.

The biasing force is applied from the position where it can be inserted into and removed from 25 toward the position where it can be moored.

Therefore, the procedure for attaching the beam 110 and the frame 100 is performed as follows. However, as described above, the horizontal frame member 10 that constitutes the frame body 100
Since 0A has substantially the same configuration as the beam 110, only the method of attaching the beam 110 will be described in detail here. As shown in FIG. 12, first, the beam 110 is inserted into the wiring space 171 through the opening 126 provided at the rear of the column. Then, the upper end side of the beam 110 is slightly inclined forward, the upper protrusion 115 is inserted into the hook hole 125 of the attachment surface 122C, and the lower end side is rotated forward with the protrusion 115 as a fulcrum to move the lower side of the lower side. The beam 110 is temporarily held by the mounting surface 122C by inserting the protrusion 116 into the hook hole 125 of the corresponding mounting surface 122C. At this time, the upper and lower hook holes 112 of the beam 110 are substantially aligned with the corresponding hook holes 125 of the mounting surface 122C. In that state, as shown in phantom in FIG. 19, the bracket 180
The outer end side of the beam 110 is tilted forward, and the engaging claw 183 is attached to the hook hole 112 of the beam 110 and the mounting surface 1 from the rear opening side of the beam 110.
22C hook hole 125 and bracket 180
Pivots the inner end side forward to a position where is substantially parallel to the beam 110, so that the outward surface 183a of the engaging claw 183 is hooked into the hook hole 11.
It abuts against the opening side edges 112a and 125a of 2,125.
Further, the rearward surface 183b of the engaging claw and the first contact side 182a
The distance m between and is substantially equal to the thickness dimension of the column and the horizontal member on which the mounting surface 122C is provided, and the bracket 180 is closely attached to the mounting surface 122C and the beam 110. Further, at both ends of the beam 110, the engaging claws 183 engage with the opening edges of the hook holes 112 and 125 in directions opposite to each other. It is supposed to not move. Then, the screw member 184 is connected to the through hole 181a of the bracket 180 and the screw insertion hole 1 of the beam 110 at the corresponding position.
13a and screw into the nut 114,
The upright wall 181 of the bracket 180 is fastened to the scaffold.
By this tightening operation of the screw member 184, as shown in FIGS. 17 to 19, the rearward surface 183b of the engaging claw 183 is pulled rearward with the rear surface of the mounting surface 122C in contact with the horizontal surface of the bracket 180. Wall 182 first
And the second contact sides 182a and 182b are the beams 11 respectively.
The upright wall 111 and the nut mounting piece 113 of 0 are abutted and pressed from the rear. That is, the hook holes 112 and 125 of the bracket 180 are opened by the tightening operation of the screw member 184 using the standing wall 111 of the bracket 180 as a scaffold.
The bracket 180 is more closely attached to the beam 110 and the mounting surface 122C while the engagement state with respect to the rim is appropriately held, and the close mounting state of the beam 110 to the mounting surface 122C of the standing wall 111 is also realized. Will be done. In addition, when changing the mounting position, the above procedure is reversed, the beam 110 is once removed from the mounting surface 122C, and the wiring space 171 is moved up and down at the desired height position as appropriate. The procedure may be to re-attach to the attachment surface 122C.

On the other hand, since the projections 100a as the temporary holding means K on the upper and lower sides of the frame body 100 both project substantially horizontally toward the mounting surface 122C, the frame body 100 has the projections 100a.
Is temporarily held on the mounting surface 122C in a state in which the entire frame body 100 is erected substantially vertically so as to be inserted substantially horizontally with respect to the hook hole 125 of the corresponding mounting surface 122C, and in that state,
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 a height change unlike the beam 110, the beam 110 and the shelves 1 together with the left and right columns 122.
I try to assemble before attaching 40 etc.

As described above, the beam 1 according to the present embodiment
The mounting structure of No. 10 is such that the facing surface 122 of the support column 122 that constitutes the pair of side support members 120 that are mounting members at the facing positions.
The bracket 180 is used between the mounting surfaces 122C which face the rear direction orthogonal to A and have the hook holes 125, respectively.
When erection 0, the beam 110 is provided with the hook hole 112 corresponding to the hook hole 125 of the mounting surface 122C, and the bracket 180 is provided with the opening edge of the hook hole 122 of the beam 110 and the corresponding hook hole 125 of the mounting surface 122C. An engaging claw 183 that can be simultaneously engaged with the opening edge, and a screw member that is a fixing unit that holds the state where the engaging claw 183 is engaged with the opening edges of the hook holes 112 and 125 and fixes the bracket 180 to the beam 110. 184 is provided, and the beam 110 is attached to the attachment surface 122C using the bracket 180.

According to this structure, the bracket 18
0 to the beam 110 and the hook holes 112 and 12 of the mounting surface 122C.
5 can be easily attached / detached to / from the beam 110.
Since the longitudinal dimension thereof can be set to be slightly longer than the inner dimension between the facing surfaces 122A, it is possible to effectively secure a mounting allowance for the support column 122 and enhance its mounting strength. Further, the columns 122 can be connected to each other by the beams 110 without a gap, and the appearance from the front can be improved. In particular, such a beam 110 is not attached to the facing surface 122A of the support column 122 but to a rearward surface orthogonal to the facing surface 122A, and it is not necessary to screw the beam to the facing surface 122A. Can be improved. Furthermore, according to such an attachment structure, the beam 110 can be attached without interfering with the facing surface 122A.
Since it can be attached to the 2C, it is possible to effectively avoid the inconvenience that the beam 110 rubs against the facing surface 122A or is caught in the facing surface 122A so that the beam cannot be inserted or removed and the facing surface 122A or the like that is easily visible from the outside is damaged. . In addition, the column 12 with the beam 110 assembled in advance
Since it can be retrofitted to 2, the attachment and detachment of the beam 110 and the change of the height position are extremely easy. Therefore, the proper mounting state of the beam 110 can be realized.

Further, the bracket 180 is attached to the engaging claw 18
Inserting into the hook holes 112 and 125 first, the engaging claw 1
Since the bracket 180 as a whole is pivotally mounted by using the base end of 83 as a fulcrum, the bracket 180 and the beam can be compared with the case where the bracket is slid to engage the engaging claw and the opening edge of the hook hole. It is possible to easily improve the degree of adhesion with the 110 and the mounting surface 122C.
It is easy to put on.

Further, the distance m between the rearward surface 183b of the engaging claw and the first contact side 182a is set to be the distance between the support column 122 and the beam 110.
Since the thickness of the upstanding wall 111 is set to be substantially equal to that of the upright wall 111, the beam 110 can be securely attached to the front and rear without rattling. Further, the engaging claw 183 is attached to the hook hole 112,
Since the ends of the beam 110 are engaged with the opening edge of the beam 110 in directions opposite to each other, it is ensured that the beam 110 does not move from that position with respect to the column 122 in the state where the bracket 183 is mounted. Can be held.

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

Particularly, as such a temporary holding means K,
Since the projections 115 and 116 projecting toward the mounting surface 122C side are provided at the upper end portion and the lower end portion of the beam 110, and these projections 115 and 116 can be inserted into and removed from the hook holes 125 of 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 effectively used even when the beam 110 is temporarily held. At this time, since the beam 110 is formed by plastically deforming a sheet metal material and a part of the beam is cut and raised to form the lower protrusion 116, such an engaging means K can be easily formed. it can.

In the present embodiment, the mounting structure of the beam 110 as described above is applied to the support column 122 which is a mounting member constituting the side support 120 of the server rack, and the rear surface of the support column 122 is used as the mounting surface 122C. Since the pillars 122 can be provided with self-supporting property, the beams 110 can be attached to the shelves 140.
Shelf 14 that can easily change the height of the rack
It can have zero.

Further, such a beam 110 is attached to the horizontal frame member 10
0A is lined up in two steps, and both ends of the vertical frame member 100
Since the frame body 100 connected by B is configured, the frame body 100 is attached to the attachment surface 122C of the support column 122 by effectively utilizing the attachment structure of the beam 110 which is easy and reliable to attach as described above. As a result, the self-supporting property of the column 122 and the strength of the rack can be further increased. Further, since both the beam 110 and the frame body 100 are attached to the support column 122 to which this embodiment is applied in the same structure,
It is possible to construct a very useful rack in which the strength of the rack is further effectively increased and the top plate 130, the shelves 140 and the like can be easily attached.

The present invention is not limited to the second embodiment described above. For example, as shown in FIG. 20 (a), the engaging claws form a portion that also projects inward of the engaging claws 283, and the rearward facing surface 283 c and the rearward facing surface 2 that projects outward.
83b and the attachment surface 122C are brought into contact with the back side and the inward surface 283d is brought into contact with the opening side edges of the hook holes 112 and 125.
Can be obtained. Also, the mounting surface 122c
The hook hole is not limited to a rectangular hole, but may have a tapered shape such that the opening width gradually narrows toward the end, as shown in FIG. 20 (b). By doing so, the engaging claws of the bracket can be more reliably engaged with the taper-shaped opening edge 325b of the hook hole 325 by restricting the rattling in the vertical direction, and thus the beam can be rattled in the vertical direction. It can be attached more securely without sticking.
Here, for the convenience of 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 engaging claws are engaged with each other. As shown by an imaginary line, a vertically divided shape or a similar shape 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 the width of 25b becomes gradually narrower toward the end, the same effect as the hook hole 325 having the tapered shape can be obtained.

Further, as shown in FIG. 21A, when a rectangular hook hole 515 is opened in a beam or the like, three of the sides that are the opening edges of the hook hole 515 are incised and the remaining one side A protrusion 51 formed at the same time as the hook hole 512 by cutting and raising along the 512b toward the mounting surface 122c side.
5 is used as the temporary holding means K,
The protrusion 515 and the engaging claw 183 of the bracket 180 can be inserted into the common hook hole 525 of the mounting surface 122c, and the protrusion 515 serves as the temporary holding means K and is attached together with the engaging claw 183. The surface 122c also serves as a final stop. Here, the case where the upper edge 512b of the hook hole 512 is cut and raised to form the upper protrusion 515 is described, but the lower protrusion 516 may be similarly formed by cutting and raising the lower edge of the hook hole 512. In such a case, the hook hole extension 5 which hook hole 525 of the mounting surface, expanding the opening of the hook holes 525 in the upper and lower edges in a substantially rectangular at its opening edge
25c is formed, and a tapered shape is formed such that the width gradually narrows toward both ends of the hook hole 525, the protrusion 515 is housed in the hook hole expanded portion 525c, and the tapered opening edge 525b is engaged. By engaging the interlocking claw 183, it is possible to more effectively prevent rattling of the beam in the vertical direction.

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

[0063]

Since the present invention has the above-mentioned structure, the following effects can be obtained. That is, in the mounting structure for a horizontal member according to the present invention, the bracket is attached to the mounting surface.
A first bracket element having an engaging claw engageable with the hook hole and a second bracket element having a restricting portion, and a position where both of these bracket elements can be simultaneously inserted into and removed from the hook hole through the biasing means; and configured so as to relative movement between a position that can be anchored to the hook holes simultaneously, before
The horizontal member is attached to the bracket hooked in the hook hole .

Therefore, it is possible to easily perform the engaging and disengaging work of the bracket with respect to the hook hole while ensuring an appropriate function of mounting the horizontal member on the mounting surface, and further, for attaching and detaching the horizontal member, etc. It is possible to maintain the proper appearance of the mounting surface and thus the furniture for a long period of time without the risk of damaging the product or opening screw holes in many places. Particularly, when the restricting portion of the second bracket element is an engaging claw that engages the opening edge of the hook hole in the opposite direction to the engaging claw of the first bracket element, the bracket itself is firmly attached to the mounting surface. Since it can be fixed to the bracket, it is possible to effectively improve the mounting strength of the horizontal member mounted via the bracket.

Further, if the horizontal member is temporarily held on the bracket and the horizontal member is fixed to the bracket at the same time when being biased by the biasing means, the labor is minimized and the horizontal member is set at the predetermined mounting position. Can be installed. If the biasing means is a screw member and both bracket elements are relatively moved through the screwing operation of this screw member, the structure can be simplified and the mounting work can be simplified, and both bracket elements can be attached. It can be securely held at the destination position.

Further, if an engaging portion for restricting the relative movement of the bracket elements to a certain range is formed between the bracket elements, it is possible to integrally handle the bracket element, and the bracket in the state of being disengaged from the hook hole can be provided. By maintaining the state where it can be inserted into the hook hole again as it is, the convenience of handling can be effectively improved, and if the engaging part has an engaging structure of the shaft part and the hole that can be relatively loosened, it is simple. It can have a different structure.

In providing such an engaging portion, the first and second bracket elements are pivotally connected to each other via a support shaft, and the engaging / disengaging state with respect to the hook hole is switched by the pivoting operation thereof. By doing so, it is possible to reduce the number of places where the engaging portion is formed to one and to facilitate the operation, and to operate the screw members and the like at one place. Further, the second bracket element is internally provided between the opposing walls of the first bracket element, and the horizontal member is attached to the position covering the first bracket element in a state where both bracket elements are inserted into the hook holes. According to this structure, it is possible to easily and surely attach the horizontal member to the bracket.

Furthermore, when the first bracket element is covered with the horizontal member, the shaft portion provided on one side is moved from the large diameter portion to the small diameter portion of the Dharma hole provided on the other side. Allows the horizontal member to be easily and reliably positioned at a predetermined position of the bracket. Since the present invention has the above-described mounting structure, even if the application target is a side support of a server rack or the like that is required to have high self-sustainability, it is possible to easily and properly change the mounting position of the horizontal member. It can be possible.

The mounting structure for a horizontal member according to the present invention also includes
In addition to the above, hook holes are provided in the horizontal member so as to correspond to the hook holes provided in the pair of mounting surfaces that are orthogonal to the facing surfaces of the pair of facing mounting members and face in the same direction. Brackets so that the engaging claws of the bracket can be engaged with the opening edges of both hook holes at the same time, and the fixing claws keep the engaging claws engaged with the opening edges of the hook holes. Is configured to be fixed to the horizontal member, and the horizontal member is installed between the mounting members.

Therefore, it is possible to secure an appropriate function of mounting the horizontal member on the mounting surface, and to easily engage and disengage the bracket with the hook holes of both the horizontal member and the mounting surface.
In addition, it is possible to effectively secure a mounting allowance for the mounting member in the horizontal member and increase its mounting strength, and also to improve the appearance in the 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 that is orthogonal to the facing surface, there is no risk of damaging the facing surface or exposing screw holes at multiple locations, maintaining the proper appearance of the facing surface and furniture for a long time. It is also possible to do.

The bracket is hooked first from the engaging claw.
Insert into the hole and bracket with the base end of the engaging claw as a fulcrum.
Due to the overall Tsu bets to be mounted in rotation, easy mounting of the bracket if rotating the bracket about its position to engage the proximal end of the engagement pawl to the opening edge of the hook hole Not only is it possible to obtain a closer fitting state of the bracket. Further, the distance between the rear surface of the engaging claw that abuts on the back side of the mounting surface and the first abutting side of the bracket that abuts the horizontal member is approximately the thickness of the hook holes into which the engaging claws are inserted. If they are equal to each other, the mounting member provided with the mounting surface and the horizontal member can be tightly sandwiched by the rearward surface of the engaging claw and the first contact side, so that it is closer and more appropriate. By engaging the engaging claws, the horizontal member can be properly attached to the attaching surface.

Furthermore, in the case where the engaging claws are engaged with the opening edge of the hook hole in the directions toward each other or in the opposite directions at both ends of the horizontal member, the engaging claws are Since the horizontal member cannot move with respect to the mounting surface in the engaged state, the horizontal member can be properly held at that position. Also, the fixing means is a screw member,
If the bracket is fixed to the horizontal member by the screwing operation and the horizontal member is fixed to the mounting surface at the same time, the mounting strength can be effectively improved with a simple structure and the horizontal member can be properly mounted. A state can be realized.

Further, when the hook hole on the mounting surface is opened so that the opening width becomes gradually narrower toward the end portion, the engaging claw of the bracket opens the hook hole more firmly.
Since the engaging claws are engaged with each other and the rattling of the engaging claws in the vertical direction is restricted, the horizontal member can be mounted more properly without rattling. Further, if the horizontal member is temporarily held on the mounting surface by the temporary holding means provided on the horizontal member and the bracket is mounted so that the hook holes of the horizontal member and the mounting surface are aligned in that state. The convenience of installing horizontal members can be reduced. In this case, if such a temporary holding means is a projection provided on the horizontal member so as to project toward the mounting surface and can be inserted into and removed from the hook hole of the mounting surface, the structure for temporary holding is separately provided on the mounting member. There is no need to make it, and the hook hole on the mounting surface can be used for both temporary holding and final fixing.

Furthermore, when a projection obtained by cutting and raising a part of a horizontal member made of sheet metal is used as a temporary holding means, such a projection can be manufactured very easily. In this case, in particular, when the hook hole is opened in the horizontal member, one of the edges of the opening is cut and raised, whereby such a protrusion can be more easily manufactured. Further, in this way, since the projection and the engaging claw can be inserted into the common hook hole of the mounting surface, the projection functions as a temporary holding means, and the engaging claw and the mounting surface are provided on the mounting surface. It can also function as a stop.

At this time, at the opening edge of the hook hole on the mounting surface, a hook hole expansion portion for expanding the opening of the hook hole is formed on at least one of the upper edge and the lower edge, and the hook hole expansion portion temporarily holds the hook hole expansion portion. By accommodating the protrusion as a means,
The projection is retracted to the hook hole expansion part and engaged with the opening edge of the hook hole, and the engaging claw is engaged with the opening side edge of the hook hole to obtain a stronger engagement state. It is possible to extremely effectively prevent rattling in the direction.

In the case of the present invention having the above-mentioned structure, when the application target is a side support member which constitutes a rack or a desk, it is possible to appropriately change the mounting position of the beam which is a horizontal member. In particular, when the horizontal members are arranged in parallel in the upper and lower two stages and the frame body whose both ends are connected by the vertical frame member is mounted on the mounting surface, the horizontal and horizontal members can be simply and properly mounted as described above. The structure can be effectively used to further improve the self-supporting property of the side support. Furthermore, if both the beam and the frame are attached to the side support, the work of assembling a rack, a desk or the like can be simplified, and the position of the beam can be easily changed after the assembling. Instead, it is possible to easily attach the top plate, the shelf, etc. by using the beam or the frame.
