DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for an optional member suspended from a shelf.

[0002]

2. Description of the Related Art Hitherto, when hanging an optional member on a shelf such as a desk or a server rack, a mounting structure using a screw and a nut has been known. That is,
In this apparatus, a nut is fixed to a predetermined position on a shelf in advance, and an optional member is positioned at that position, and then a screw can be fastened to the nut.

[0003]

However, in such a configuration, the nut must be fixed in a predetermined position in advance, which not only complicates the work process but also eliminates the need for optional members. Since the nuts remain on the shelf, various problems occur, such as unnecessarily increasing the manufacturing cost. Further, since the load of the optional member is concentrated on the screw, the screw is likely to be damaged, and if the screw is accidentally removed, there is a risk that the optional member may fall.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides an optional member mounting structure which requires no screws or nuts and can be securely attached and detached by a simple operation.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the mounting structure for an optional member according to the present invention, when the optional member is mounted in a suspended state on a shelf having a reinforcing portion on the lower surface side, an optional member is provided between the reinforcing portion and the optional member. By sliding the member to one side to form a related portion for engaging the two members, the related portion allows the reinforcing portion to support the load of the optional member at a position where the shelf and the optional member are engaged, and at this position, It is characterized in that the optional member is attached to the shelf by detachably attaching a regulating member that regulates the sliding movement of the optional member to the other between the and the optional member.

According to this structure, the load of the optional member can be supported mainly by the related portion in the reinforcing portion, and a large load is not applied to the restricting member. Therefore, a screw or a nut is not used as the restricting member. However, a simple structure that does not require much strength can be used.
Therefore, unlike the conventional case, it is not necessary to fix the nut to the shelf in advance, and it is possible to reduce the number of working steps and costs. In addition, since the mounting operation simply involves sliding the optional member with respect to the shelf and associating the related parts with each other to mount the regulating member, the operation process is simple and unnecessary nuts are not left on the shelf. In addition, since the optional member is supported not on the face plate portion of the shelf but on the reinforcing portion, stable support is possible, and damage such as dents on the face plate portion can be prevented.

In such a configuration, in order to more easily and surely restrict the movement of the optional member by the restricting member, the restricting member is attached to the shelf with the distal end attached to the shelf and the optional member. Is desirably configured so as to restrict the movement of the optional member. In this case, in order to facilitate attachment and detachment of the regulating member, it is preferable that the tip of the regulating member be deformed by elastic deformation. As one in which such a regulating member can be attached with a single touch, the regulating member includes the distal end portion and a proximal end portion pushed into the distal end portion, and the distal end portion is pushed into the distal end portion side to push the distal end portion toward the distal end side. There is one that deforms the part.

[0008] On the other hand, in order to simplify the structure of the related part so that the shelf and the optional member are properly engaged with each other and can reliably support the load of the optional member, the related part must be either a shelf or an optional member. It is desirable to comprise a concave portion provided on one side and a convex portion provided on the other side and slidable along the concave portion while being inserted into the concave portion. Further, a more stable mounting state of the optional member can be obtained while restricting the movement of the optional member to the other side, and another example of the easily adjustable mounting member is through the shelf and the optional member. And a metal fitting that has a screw hole that engages with the screw element by a screw action at a position where the shelf and the optional member are engaged with each other by an associated portion and that can be mounted from the outside.

[0009] In this case as well, the shelf and the optional member are appropriately engaged with each other with a simple structure, and the related part that can reliably support the load of the optional member is provided on either the shelf or the optional member. It is desirable to have a concave portion and a convex portion provided on the other side and slidable along the concave portion in a state inserted in the concave portion. Further, the structure of the regulating member is effectively used by effectively using the structure of the related portion. To facilitate attachment and detachment, an insertion hole is formed at a position corresponding to the start end side of the sliding movement of the convex portion of the concave portion on the side where the convex portion of the shelf or the optional member is provided, and the metal fitting is formed with the concave portion and the insertion hole. It is effective to pass through and attach.

[0010] Further, a metal fitting which can be easily attached and detached and can be firmly attached after engaging with the screw element includes an upper piece having a screw hole located on the shelf side and One that includes an upright piece that is positioned in the concave portion and the insertion hole and that stands up, and a lower piece that is positioned on the option member side, and has a crank shape in a side view. In this case, the width of the lower piece should be adjusted to prevent the fitting from passing upward through the recess due to the vibration of an earthquake or the like, even if the fitting is attached or detached by mistake or if the screw element is slightly loose. It is desirable that the width is set larger than the maximum width dimension of the concave portion.

As a specific embodiment of the related portion, the concave portion is a darma hole in which the small-diameter portion and the large-diameter portion are integrally connected, and the convex portion is inserted into the large-diameter portion and engages with the small-diameter portion. A stepped pin whose upper end is larger in diameter than the lower end so as to fit, or a recess is a slit whose other end is narrower than one end, and a protrusion is one end of the slit Associated with the other end.

When the optional member has a certain width or depth, a plurality of related parts are required to stably support the optional member. In order to simplify the mounting process by sliding only in the direction, a plurality of recesses are provided on either the shelf or the optional member,
It is desirable that the relationship between the insertion position of the convex portion in the concave portion and the engagement position is set in the same direction in all the concave portions. Preferable examples of such a specific arrangement direction of the concave portions include a plurality of concave portions arranged side by side in at least one of the left, right, front and rear directions.

As an optional member preferable for applying the above-described mounting structure, a task light, a hanging shelf, or the like can be given.

As shown in FIGS. 4 and 5, the horizontal wall 16a constituting the lower end of the reinforcing bar 16 has a plurality of darma holes 17 as recesses of the present invention at intermittent positions along the longitudinal direction. (8 in the illustrated example). The darma hole 17 includes a pair of continuous large-diameter portions 17a and small-diameter portions 17b, and the large-diameter portions 17a are positioned ahead of the small-diameter portions 17b. Here, in each of the reinforcing bars 16, the positional relationship between the large-diameter portion 17a and the small-diameter portion 17b of each dharma hole 17 is set so as to be in the same direction.
All the darma holes 17 are arranged so as to be substantially in a straight line on the left and right, and this relationship is common to all the reinforcing bars 16. Further, in all the reinforcing bars 16, the darma holes 17 are set so as to be substantially aligned in the front-rear direction. Further, the reinforcing bar 1 disposed at the rear end 1b and the central portion
6 has a large diameter portion 1 of each of the dharma holes 17 on the horizontal wall 16a.
A substantially circular through hole 18 is provided at a position forward of 7a. The reinforcing bar 16 disposed at the front end 1a is not provided with such a through-hole, but the bottom wall 15 is located forward of the large-diameter portion 17a of the darma hole 17 of the reinforcing bar 16 in the direction described above. A similar through hole 18 is provided.

The upper shelf 2 shown in FIG. 7 is set to have a smaller depth than the middle shelf 1. Therefore, although not shown, the middle shelf 1 is provided only at the front end 2a and the rear end 2b. The reinforcing bars similar to the reinforcing bars 16 at the front end portion 1a and the rear end portion 1b are provided. The rest of the configuration is substantially the same as that of the middle shelf 1, and the description is omitted. On the other hand, as shown in FIGS. 3 and 4, the task light 3, which is an optional member, includes a cover 32 that accommodates a lighting device such as a fluorescent lamp 31 and a mounting plate 33 that stands upright at the rear end of the cover 32. It becomes. The wiring (not shown) of the fluorescent lamp 31 is led to the wiring duct 7 through the side wiring space S or the like. The mounting plate 33 includes an upright portion 33a arranged along the rear end of the cover 32, and an inverted L-shaped bent portion 33b bent forward and laterally at both end portions of the upright wall 33a. Horizontal wall 3 forming the upper end of bent portion 33b
3c, the stepped pin 34, which is a convex portion of the present invention, is attached upward. The stepped pin 34 is formed by integrally forming a disk-shaped head 34a disposed at the upper end and a columnar neck 34b disposed at the lower end and having a smaller diameter than the head 34a. In addition, the central axes of the head 34a and the neck 34b are substantially aligned, and the lower end of the neck 34b is fixed to the horizontal wall 33c. The stepped pin 34 and the darma hole 17 form a related portion X. Here, the size of the head portion 34b is set smaller than the large diameter portion 17a of the daruma hole 17 and larger than the small diameter portion 17b, and the cross-sectional shape of the neck portion 34b is set slightly smaller than the small diameter portion 17b. ing. A substantially circular through hole 35 is formed in the horizontal wall 33c ahead of the stepped pin 34. The distance d1 between the center axis of the stepped pin 34 and the center of the through hole 35 is equal to the small diameter portion 17 of the dharma hole 17 in the middle shelf 1.
The distance is set to be substantially equal to the distance d2 between the center of b and the center of the through hole 18.

Further, in this embodiment, when the task light 3 is mounted on the middle shelf 1, a state is shown in FIG. 4 and FIG. As described above, the regulating member 8 that can be inserted into the through holes 18 and 35 is used. The restricting member 8 includes a base end 8a.
The plunger 81 is made of a resin and includes a plunger 81 arranged on the side and an expanding / contracting part 82 arranged on the side of the distal end portion 8b and accommodating a part of the plunger 81 so that the plunger 81 can be pushed in. The expanding / contracting portion 82 is provided with a plurality of slits 82a in the up-down direction. When the shaft portion 81a of the plunger portion 81 is not pushed in normally, FIGS.
As shown in FIG. 7, the slit 82a is closed and has a diameter small enough to be inserted into the through holes 18 and 35. However, when the plunger portion 81 is pushed in, the elastic portion of the resin is deformed from the inside by the shaft portion 81a. The slit 82a of the expanding / contracting portion 82 is pushed and widened so as to be wider than the through holes 18 and 35.

In this embodiment, however, the task light 3 is attached so as to be hung on the reinforcing bar 16 provided at the center of the middle shelf 1. At this time, as shown in FIGS. 4 and 6, first, the heads 34 a of the pair of stepped pins 34 provided on the task light 3 are connected to the large diameter portions 17 a of the corresponding pair of daruma holes 17 of the reinforcing bar 16. Then, the task light 3 is slid rearward as shown by the arrow in the figure, and the neck 34b of the stepped pin 34 is engaged with the opening edge of the small diameter portion 17b, and the task light 3 is positioned at that position. 3 is temporarily held. By doing so, the through-hole 18 of the middle shelf 1 and the through-hole 35 of the task light 3 substantially coincide vertically. Then, the expanding / reducing portion 82 of the regulating member 8 is inserted into the through holes 18 and 35 from below, and the plunger portion 81 is turned upward by a series of subsequent operations so that the shaft portion 81 a
Is pushed into the expansion / contraction section 82, the expansion / contraction section 82 is expanded. By the operation of attaching the regulating member 8, the stepped pin 34 of the task light 3 is moved from the small diameter portion 17b side to the large diameter portion 1b.
The movement to the 7a side is restricted, and the attachment of the task light 3 is completed. When the attached task light 3 is removed, the above operation may be performed in reverse.

In this embodiment, the task light 3 and the middle shelf 1, which are optional members, are structured as described above.
By sliding the task light 3, the daruma hole 17 and the stepped pin 34 forming the related portion X are engaged with each other, so that the load of the task light 3 is supported by the reinforcing bar 16 as the reinforcing portion of the middle shelf 1. It will be. Therefore,
Since a large load is not applied to the regulating member 8 inserted into the through holes 18 and 35 provided in the middle shelf 1 and the task light 3 so as to regulate the sliding movement of the task light 3 in the reverse direction,
The regulating member 8 can be made of a synthetic resin that does not require much strength with a simple configuration. This eliminates the need to fix the nut to the middle shelf 1 in advance, and can effectively reduce the number of working steps and costs. further,
The work required for attaching the task light 3 is only the sliding movement with respect to the middle shelf 1 and the attaching of the regulating member 8, so that the working process can be simplified. Also, since optional members such as the task light 3 are attached to the reinforcing bar 16, for example, a through hole is formed in the upper wall 11 which is a face plate portion of the middle shelf 1 or the like, and a server or the like is mounted through a belt or the like in the through hole. Even when the object is fixed, it is possible to prevent the optional member from interfering with the belt or the object.

Particularly, in this embodiment, when the regulating member 8 is attached to the middle shelf 1 and the task light 3 at the same time, the tip 8b
Is expanded and deformed, the movement of the task light 3 by the regulating member 8 can be restricted simply and reliably. Furthermore, since the deformation of the expansion / contraction portion 82 is due to the elastic deformation of the resin that is the material of the regulating member 8, a special structure for the deformation is not particularly required, and the regulating member 8 can be easily attached and detached. it can. Furthermore, since the restricting member 8 is deformed by pushing the plunger portion 81 on the base end portion 8a side into the expanding and contracting portion 82 on the distal end portion 8b side, the restricting member 8 can be easily formed by a series of one-touch operations. It is possible to attach.

The related portion X of the present embodiment is composed of a dharma hole 17 serving as a concave portion provided on the middle shelf 1 and a stepped pin 34 serving as a convex portion provided on the task light 3. 34 is inserted into the large diameter portion 17a of the dharma hole 17 and the small diameter portion 1 is inserted.
7b, the middle shelf 1 and the task light 3 can be easily associated with each other at the related portion X, and the load of the task light 3 can be reliably supported by the middle shelf 1.

Further, when a plurality of darma holes 17 are provided in the reinforcing bar 16 of the middle shelf 1, a small-diameter portion which is engaged with the large-diameter portion 17a where the stepped pin 24 is inserted in all the dharma holes 17 is provided. Since the positional relationship with the slide 17b is set in the same direction, the direction of the sliding movement of the task light 3 is set in one direction, so that the manufacturing labor and the mounting process can be simplified. In particular, since the plurality of daruma holes 17 are paired on the left and right, the task light 3 having a large width can be stably supported. Further, in the middle shelf 1, since the dharma holes 17 are also paired in the front-back direction, as shown in FIG. It is also useful when mounting. That is, since the same stepped pins 34 as those described above are provided at the four corners of the upper wall 131 in the hanging shelf 130, the hanging shelf 13 is inserted into the dharma hole 17 in which the sliding movement direction is all set backward.
0 can be easily attached and can be stably supported.

Further, the task light 3 and the hanging shelf 130 are applied as optional members. Such a task light 3 can be mounted at a required position on the middle shelf 1 or the upper shelf 2 according to the working position, so that the task light 3 is very easy to use. Further, since the hanging shelf 130 is attached to the reinforcing bar 16, even if the object stored in the hanging shelf 130 is heavy, it can be stably supported.

In the above description, the case where the task light 3 is attached to the reinforcing bar 16 arranged at the center of the middle shelf 1 has been described. However, the case where the task light 3 is attached to the other reinforcing bars 16 of the middle shelf 1 and each reinforcing bar of the upper shelf 2. And the same operation may be performed, and the same effect as above can be obtained. Further, the present invention is not limited to the above embodiment. For example, as shown in FIG. 9, the related portion X2 forms a slit 217 as a concave portion on the shelf (not shown) in which the other end 217b side is narrower than the one end 217a side, and is associated with the slit 217 as a convex portion. The same effect as in the above embodiment can be obtained even if the matching related claw 234 is provided on an optional member (not shown).

As the restriction member 380 other than the above, there can be mentioned those shown in FIGS. In this example, the task light 3 is applied as an optional member in the same manner as in the above-described embodiment, and the dharma hole 17 and the task light 3 provided on the reinforcing bar 16 of the middle shelf 1 as concave portions and convex portions constituting the related portion X are provided. Stepped pin 34 provided at
Has been applied. The restricting member 380 includes the screw element 38
1 and a metal fitting 382 having a screw hole 384 that engages with the screw element 381 by a screw action.
The metal fitting 382 is formed by bending a sheet metal material so as to form a substantially crank shape in a side view, and includes a substantially horizontal upper piece 382a and lower piece 382c, and upper and lower pieces 382a and 382c.
and erected piece 382b that stands at a position where c is connected at one end. The screw hole 383 is formed in the upper piece 382a. Further, when the task light 3 is attached to the reinforcing bar 16 by engaging the stepped pin 34 with the small diameter portion 17b of the dharma hole 17, when the task light 3 is attached to the horizontal wall 33c of the attaching plate 33 of the task light 3 corresponding to the large diameter portion 17a. Is provided with a rectangular insertion hole 36 in a plan view, which is opened in a size that allows the upper piece 382a and the upright piece 382b of the metal fitting 382 to be inserted. When the metal fitting 382 is attached, the lower piece 382c is held in hand and the upper piece 382a is inserted from below into the insertion hole 3.
6 and the large diameter portion 17a, and the tip side
7 and the upright piece 382b is positioned in the insertion hole 36 and the large-diameter portion 17a to be erected. Here, the screw hole 383 provided in the upper piece 382a is set at a position corresponding to the through hole 18 and the through hole 35 of the task light 3 located therebelow. Furthermore, the width dimension d1 of the lower piece 382c of the metal fitting 382
Is set to be larger than the diameter d2 of the large diameter portion 17a. In this state, the screw element 381 is inserted into the through holes 35 and 18 from below and is engaged with the screw hole 383 of the metal fitting 382, so that the screw element 381 and the upper piece 382a allow the horizontal wall of the task light 3 to be connected. 33c and the horizontal wall 16a of the middle shelf 1 are fastened together, and the movement of the stepped pin 34 toward the large-diameter portion 17a is restricted.

Therefore, as described above, the screw element 381
The movement of the task light 3 in the direction opposite to the direction in which the stepped pin 34 is engaged with the daruma hole 17 can also be easily regulated by the regulating member 380 composed of the metal member 382 having the screw hole 383. Further, with such a regulating member 380, it is possible to restrict the movement of the task light 3 and, at the same time, firmly fix the task light 3 to the middle shelf 1 to strongly support the load of the task light 3; It is possible to make the mounting state of the light 3 more firm and stable. Further, similarly to the above-described embodiment, the related portion X is provided in the reinforcing portion 16 of the middle shelf 3 and the dharma hole 17 as a concave portion and the task light 3 as an optional member are provided.
And the insertion hole 3 is provided at a position corresponding to the large-diameter portion 17a of the dharma hole 17 on the task light 3 side, which is the starting end side of the sliding movement of the stepped pin 34.
6 is provided, and the fitting 3 is provided in the insertion hole 36 and the large diameter portion 17a.
Since the 82 is inserted, the configuration of the related portion X can be effectively used without forming a special mounting structure for attaching and detaching the regulating member 380.

Further, the metal fitting 382 is formed by an upper piece 382.
a, which has a crank shape in a side view including a standing piece 382b and a lower piece 382c. A screw hole 383 is formed in the upper piece 382a positioned on the side of the middle shelf 3 and the standing piece 38 is formed.
2b is positioned upright on the large diameter portion 17a and the insertion hole 34, and the lower piece 382c is positioned on the task light 3 side. Therefore, the lower piece 382c is held by hand and the bracket is arranged at a predetermined position. The work efficiency can be further improved, and the attachment state of the task light 3 can be improved. Moreover, the lower piece 382c of the metal fitting 382
Has a width d1 which is larger than the diameter d2 which is the maximum width of the large diameter portion 17a of the darma hole 17, so that the engagement with the fitting 382 and the engagement with the screw element 381 are somewhat loose. In this case, even when the fitting 382 does not pass upward through the large-diameter portion 17a even in the case of a bounce caused by vibration such as an earthquake, the fitting state of the fitting 382 can be made firm.

The metal fitting is not limited to a metal fitting that can be mounted from below, as long as the metal fitting can be mounted on the reinforcing portion from the outside such as a side. Further, a concave portion such as a dharma hole may be provided on the upright wall instead of the horizontal wall of the reinforcing bar, and the optional member may be slid up and down.The reinforcing portion may be something other than the reinforcing bar, Of course, the concave portion may be formed on the optional member and the convex portion may be formed on the shelf. Further, the sliding direction of the optional member is not limited to the depth direction of the shelf as in the above embodiment, but may be the width direction.

In addition, the specific configuration of each part, such as the configuration of the regulating member, is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

Further, the regulating member is constituted by a screw element penetrating the shelf and the optional member, and a metal fitting having a screw hole, which can be attached from the outside, and the screw element and the screw hole at a position where the shelf and the optional member are engaged with each other. In the case of the engagement, the movement of the optional member to the other can be easily restricted in the same manner as described above, and further, the attachment and detachment of the fitting and the screw element are easy, and the mounting state of the optional member is Can be extremely stable.

In this case, a concave portion is provided on one of the shelves or the optional member as a related portion, and a convex portion is provided on the other.
After inserting the convex part into the concave part, it is configured to slide along the concave part, and the metal fitting is inserted on the side where the convex part is provided so as to correspond to the part of the concave part which is the starting end side of the sliding movement of the convex part. By forming an insertion hole that can be formed, not only the related portion having a simple structure can be easily formed, but also by using the configuration of the related portion effectively when attaching and detaching the bracket, by opening the insertion hole, etc. It is possible to eliminate the necessity of providing a special configuration for the camera.

Further, assuming that such a metal fitting has a crank shape in a side view, the upper piece is positioned on the shelf side to form a screw hole, the upright piece is positioned in the recess and the insertion hole, and the lower piece is raised. In the case where it is positioned on the optional member side, working efficiency can be effectively improved, such as handling the metal fitting by holding the lower piece by hand, and the mounting state of the metal fitting can be firm. In particular, if the width of the lower piece is set to be larger than the maximum width of the recess, the fitting does not pass upward through the recess even when attaching or detaching the fitting or even if the screw element is loose. And stability can be further improved.

Specifically, when the concave portion is a darma hole and the convex portion is a stepped pin, or when the concave portion is a slit having a narrower end than the one end, the convex portion is a related claw that engages with the slit. In addition, it is possible to configure a related portion that realizes reliable engagement and support of the optional member. Further, when providing a plurality of concave portions in the related portion, if the relationship between the insertion position of the convex portion and the engaging position is set in the same direction in all the concave portions, the width dimension or the depth of a certain size Since the optional member having the dimensions can be stably supported and the direction of the sliding movement of the optional member can be set in one direction, the labor and the mounting process of manufacturing can be simplified. When a plurality of such recesses are arranged so as to form a pair in at least one of the front, rear, left, and right directions, even if the width and depth dimensions of the optional member are relatively large, the support of the optional member is correspondingly stable. Can be realized.

When the task light is mounted on the mounting structure having the above configuration, it is easy to change the mounting position according to the working position. Also, when installing a hanging shelf,
Even if a heavy object is supported by the hanging shelf, the hanging shelf is supported by the reinforcing portion, so that extremely stable supporting of the hanging shelf can be realized.
