The structure of the shelf is such that there is no protrusion outward from both side surfaces so that the racks 1 and 4 will not be caught during installation, and the practical internal dimension for mounting the tabletop device 3 Needed to be large. Particularly for the latter, it is necessary to make the inner dimension of the rack as large as possible under the condition that the inner dimension a of the racks 1 and 4 is determined by the standard.

The shelves also need to be mounted horizontally.

[Conventional technology]

 FIG. 10 and FIG. 11 show a conventional tabletop device mounting shelf structure.

10 is a shelf, and the bottom plate portion 10a and the side plate portions 1 on both sides of which are raised
It consists of 0b and 10c.

Reference numerals 11 and 12 denote L-shaped mounting fittings, each of which includes a main body portion 11a, 12a and a flange portion 11b, 12b.

The mounting brackets 11 and 12 are attached to the shelf 10 by screwing the first screws 13 from the lateral outside of the shelf 10 and screwing the body portions 11a and 12a to the outer side surfaces of the side plate portions 10b and 10c. .

In this shelf 10, the second screw 14 is screwed in from the front side of the rack 1 (4), and the flange portions 11b and 12b of the mounting bracket 11 are racked.
It is attached to the rack 1 by being screwed to (4).

[Problems to be solved by the device]

As shown in FIG. 10, the heads 13a of the first screws 13 project on both sides of the shelf 10, and the width dimension of the portion inserted into the rack 1 is the height of the screw heads 13a. Since the double dimension of the dimension b is included, the width dimension W ₁ of the shelf 10 is shortened accordingly. Further, the tip end portion 13b of the first screw portion 13 projects from the both sides of the shelf 10 to the inside of the shelf 10 by a dimension c. As a result, the width dimension of the part where the desktop device 3 can be mounted is further limited, and W ₂
Will be.

In addition, when the tabletop device 3 is mounted on the shelf 10, the side surface may rub the screw tip portion 13b and damage it.

Further, when the shelf 10 is inserted into the rack 1 to attach the shelf 10 to the rack 1, the screw heads 13a collide with the rack 1 and in some cases, the rack 10 cannot be inserted to the final position. There is also a risk that it will not be possible to attach it to 1.

Furthermore, since there is no standard for determining the attitude of the mounting brackets with respect to the shelf 10 when mounting the mounting brackets 11 and 12,
As shown in FIG. 11, it may be mounted in a slightly inclined state. In this case, the shelf plate is twisted or tilted when it is attached to the rack.

It is an object of the present invention to provide a tabletop device mounting shelf structure capable of expanding a space in which a tabletop device can be mounted.

[Means for Solving the Problems]

The present invention has a bottom plate part and side plate parts standing on both sides of the bottom plate part, and mounting brackets are fixed by first screws on both sides of a shelf on which a tabletop device is mounted. Second
In the tabletop device mounting shelf structure in which the shelf is fixed to the rack by fixing with screws, the mounting metal fittings are attached to the main body portion facing the outer surface of the side plate portion, and the inside of the lower portion of the main body portion. A bottom plate supporting portion bent in an L shape to support the bottom plate portion, and a bottom U-shaped bending portion formed inwardly in an upper portion of the main body portion so as to be sandwiched by the upper edge side of the side plate portion. And a flange part that is bent in an L shape outward from the front edge of the main body part and is screwed to the rack by the second screw, and the mounting metal fitting is the sandwiching part. In the state where the side plate part is sandwiched, the bottom plate support part is fixed to the shelf by being screwed from the lower side to the bottom plate part by the first screw.

[Action]

Since the mounting bracket is fixed to the shelf by being screwed from the bottom plate side of the shelf, it is possible to avoid narrowing the width of the portion where the desktop device can be mounted due to the screw head and the screw tip.

〔Example〕

FIG. 1 and FIG. 2 respectively show a tabletop-equipped shelf structure according to an embodiment of the present invention.

20 is a shelf, 21 is a rack, and 22 and 23 are fittings.

Like the conventional shelf 10, the shelf 20 includes a bottom plate portion 20a and side plate portions 20b and 20c standing on both sides of the bottom plate portion 20a. A plurality of screw holes 20d are formed along the side plate portions 20b and 20c of the bottom plate portion 20a.

As shown in FIG. 3, the mounting bracket 22 includes a main body portion 22 _-1 facing the side plate portion 20b, and an L-shaped bent inward from the lower portion of the main body portion 22 _{-1 to} the side plate portion of the bottom plate portion 20a. A bottom plate support portion 22 _-2 for supporting a portion near the 20b and an inverted U-shape bent inward are formed in the upper portion of the main body portion 22 _-1 , and are fitted to the upper edge portion 20b-1 side of the side plate portion 20b. It has a shape including a sandwiching portion 22 _-3 which sandwiches the lever and a flange portion 22 _-4 which is bent in an L shape outward from the front edge of the main body portion 22 _-1 .

The mounting bracket 23 on the opposite side has a shape symmetrical to the mounting bracket 22 described above, and includes a main body 23 _-1 , a bottom plate supporting portion 23 _-2 , a sandwiching portion 23 _-3 ,
And mounting bracket 22 more the flange portion 23 _-4, the upper edge of the first view and as shown in FIG. 2, the main body portion 22 _-1 of the side plate portion 20b nip 22 _-3 side plate portions 20b 20
b-1 is fitted and sandwiched, the bottom plate supporting portion _22-2 is _attached to the bottom plate portion 20a, the main body portion _22-1 is attached to the side plate portion 20b, and is attached to the right side portion of the shelf 20. The bottom plate supporting portion 22 _-2 is screwed to the bottom plate portion 20a from the lower surface side of the shelf 20 by the screw 13 of
Fixed on shelf 20.

The other mounting bracket 23, like the mounting bracket 22 above,
Fixed at 22.

The shelf 20 is inserted into the rack 21, and the flange portions 22 _-4 , 23 _-4 of the mounting brackets 22, 23 fixed on both sides are screwed to the rack 21 from the front side of the rack 21 with the second screw 14. Fixed.

The tabletop device 3 is mounted on the shelf 20 fixed in this way.

Here, the features of the shelf structure will be described.

The first screw 13 for fixing the mounting brackets 22 and 23 to the shelf 20 is the shelf 20.
Since the screw head 13a is screwed from below rather than from the side surface side, the screw head 13a does not project to the side of the shelf 20.

Therefore, as can be seen from FIG. 4 which is shown in comparison with the conventional example, the width dimension W ₃ of the shelf 20 is equivalent to twice the height of the screw head 13a compared to the width dimension W ₁ of the conventional shelf 2. It can be widened by the size of
Further, the screw tip portion 13b does not protrude from the side surface side of the shelf 20. As a result, the width dimension of the portion on which the tabletop device is mounted becomes larger than the conventional width dimension W ₂ and becomes W ₄ .

As a result, the tabletop device 3 can be mounted with a margin larger than that in the conventional case, and the tabletop device having a wider size than the conventional case can be mounted.

Further, since the tip end portion 13b of the screw does not protrude from the side surface side of the shelf 20, the tabletop device 3 is not damaged during mounting.

The tip portion 13b of the screw protrudes from the bottom plate portion 20a of the shelf 20, but the tabletop device 3 has the rubber feet 3a, and the main body of the desk device 3 is lifted from the bottom plate portion 20a by the dimension d, so that there is no problem.

Further, since the screw head 13a does not project to the outside of the side surface of the shelf 20, the shelf 2 to which the mounting brackets 22 and 23 are attached
When inserting into the rack 21 to attach the 0 to the rack 21,
The screw head does not hit the rack 21 and the rack 20 can be attached to the rack 21 without any trouble.

Further, the sandwiching portions 22 _-3 and 23 _-3 sandwich the side plate portions 20b and 20c, and the mounting brackets 22 and 23 are also fitted to the shelf 20 on the upper side portions. For this reason, although the mounting brackets 22 and 23 are screwed only on the lower side, they are firmly mounted to the shelf 20.

If you do not have the pinching part 22 _-3 ,
Depending on the case, 25 may be warped outward as shown by the chain double-dashed line in FIG. 6, and it may not be possible to insert the shelf 20 into the rack 21, but as shown in this embodiment, it is pinched. Part 22 _-3 , 23 _-3
In the case where the main body 22 _-1 , 23 _-1 is provided, the position of the main body 22 _-1 , 23 _-1 is restricted also on the upper portion thereof, and the main body 22 _-1 , 23 _-1 is provided with the side plate 20
The side plates 20b, 20c are brought into contact with the side plate portions 20b, 20c over the entire surface without floating from the b, 20c. This also allows the rack 21 of the shelf 20 to
It is possible to prevent the main bodies 22 _-1 , 23 _-1 from colliding with the rack 21 when inserted into the inside.

Further, the presence of the sandwiched portion 22 _-3 also has the following effects.

That is, when the mounting position of the mounting bracket 22 is changed according to the rack, even if the first screw 13 is removed, the mounting bracket 22
Is stuck on the shelf 20 and cannot be removed. Therefore, the pinch
_22-3 is a slider, and the mounting bracket 22 is the arrow A, B in FIG.
It is possible to slide the slider in the direction, adjust the position to a new position, and screw it in again, which makes the work easier than in the past.

Further, the mounting brackets 22 and 23 have bottom plate supporting portions 22 _-2 and 23 _-2 , which are bent and formed with respect to the main body portions 22 _-1 and 23 _-1 , respectively.
It is attached closely to the flange part 22 _-4 , by simply screwing it without using a special jig.
23 _-4 is in a state of being perpendicular to the longitudinal axis l of the side plate portions 20b, 20c. That is, the fittings 22 and 23 are screwed with high precision and workability.

Since the mounting precision of the mounting brackets 22 and 23 to the shelf 20 is good, the shelf 2
When 0 is attached to the rack 21, its level is accurately determined. Therefore, the tabletop device 3 is also stably placed.

[Effect of device]

As described above, according to the present invention, since the head of the screw for mounting the mounting bracket does not project to the side and the tip of the screw does not project from the side surface in the shelf, the tabletop device on the shelf is mounted. The space for placing it can be made wider than before, and the rack can be attached to the rack without any problems.

Further, since the mounting metal fittings are mounted in close contact with the bottom plate of the shelf, they can be fixed with high accuracy without variation, and the shelf after mounting on the rack can be favorably leveled.
