Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an office desk or a learning desk, and more particularly to a top plate mounting structure thereof.

[0002]

2. Description of the Related Art Heretofore, some desks for office use and the like include, for example, a top plate and side panels serving as legs attached to lower surfaces of left and right ends of the top plate. To attach the top panel to the side panel, from the viewpoint of ease of work and reduction of the number of parts, etc., tighten the side panel and the top panel by tightening the bolts only on the end side of the top panel and tightening the top panel. The entire plate is fixed to the side panel. That is, the top plate, in the hole formed on the side opposite to the end of use, is fitted with a projection provided forward and horizontally on the block fixed to the back side of the side panel,
The bolts are tightened from below the top plate on the use end side with the projections sufficiently fitted in the holes. In such a structure, the protrusion inhibits the left, right, up, and down movement of the top plate on the side opposite to the use end.

[0003]

By the way, in the above-mentioned structure, the projection and the hole are simply fitted to each other on the non-use end side of the top plate, and the projection attached to the side panel side is It does not act to pull the top plate toward the side panel, nor does it pull the top plate toward the back side. Moreover, even on the use end side of the top plate, the top plate is pulled to the side panel by the bolt, but the top plate is not pushed to the opposite end side. Therefore, when the inner diameter of the hole and the outer dimensions of the protrusions are not within the predetermined dimensional error range, the counter plate end of the top plate is rattled in any of left, right, up, and down directions.

In such a structure, the number of bolts is reduced because the bolts are tightened in two places on the top plate.
As a result, the bolt tightening work is reduced, so that it is possible to reduce the number of parts. However,
In order to prevent the bolts from being exposed from the top plate, the bolt tightening work must be done from the bottom of the top plate upwards.Though the bolt tightening work is reduced, it does not necessarily mean that the work can be done in a comfortable position and the work is not always easy. It doesn't come.
An object of the present invention is to eliminate the above-mentioned problems with a simple structure.

[0005]

The present invention takes the following means in order to achieve such an object. That is, the desk according to the present invention is a desk in which a top plate is placed on the upper surface of the leg element, and the table is provided between the use end side of the top plate and the leg element in the direction opposite to the use end of the top plate. A slide engaging part that engages with each other by sliding is provided, and the top plate is fixed while being pulled in to the non-use end side by screwing operation from above between the anti-use end side of the top plate and the leg element. A tightening mechanism is provided, and the tightening mechanism is pivotally attached to the leg element so that the engaging hole provided on the lower surface of the top plate and the hook-shaped portion at one end face the engaging hole, and the leg element can swing. A balance member whose end is located on a threaded portion provided on the leg element, and the threaded portion is screwed onto the threaded portion and the other end of the balance member is tightened to the upper surface of the leg element to engage the hook-shaped portion at the one end with the engagement. And a screw element for engaging the hole.

The desk according to the present invention may be of a type in which the top plate is arranged on the leg elements so as to face each other, in addition to the ordinary one-sleeve type and the two-sleeve type. . The slide engaging portion that engages the use end side of the top plate and the leg element has an engagement hole formed in one of the top plate and the leg element and a protrusion hole formed in the other and engaged with the engagement hole. Those having a hook-shaped claw that can be fitted are preferable.

[0007]

With this structure, the slide engagement portion fixes the use end side of the top plate to the leg element and the tightening mechanism fixes the non-use end side of the top plate to the leg element. The slide engagement part is
Since the top plate is formed so as to be engaged with each other by sliding it in the direction opposite to its use end, if the top plate is placed on the leg element and the top plate is slid, the use end side of the top plate will be Fixed.

Further, the tightening mechanism includes an engaging hole on the lower surface of the top plate,
By configuring the balance member that is swingably provided on the leg element and the screw element that tightens the other end of the top plate member to the upper surface of the leg element, the screw element is screwed to the thread portion of the leg element and the leg element is screwed. The other end of the top plate member is tightened on the upper surface of the element, so that the hook-shaped portion of the balance member is engaged with the engagement hole. In this case, since the balance member swings, the hook-shaped portion draws an arc and moves upward,
When engaging with the engaging hole of the top plate, the engaging hole is pulled in the direction opposite to the use end. Therefore, the top plate further slides in the direction opposite to the end to be used, the slide engagement portion strengthens the engagement state by the engagement between the balance member and the engagement hole, and the hook-shaped portion of the balance member engages. Since it is engaged with the dowel, lifting of the other end of the top plate is prohibited.

Further, if the slide engaging portion is provided with the engaging hole and the hook-shaped pawl, the engaging work is facilitated and the hook-shaped pawl is engaged with the engaging hole. Therefore, the top plate can be firmly fixed to the leg element.

Is being worn. Further, the hook-shaped claw 45 is made of sheet metal, and the lower side of the channel-shaped front end portion 45 a is cut out, and functions as a guide when engaging with the front engaging hole 14 of the top plate 1. .

The intermediate leg 5 is different from the side panel 4 in that
There are no legs at the lower end of the body 51, and the top plate 1 is at the upper end.
The arm portion 52 for supporting is only provided so as to extend in the depth direction. Even in this intermediate leg 5, just like the side panel 4, on the upper surface 52a of the arm portion 52,
The tightening metal fitting 7 and the hook-shaped claw 45 are fixed to each other. The depth dimension of the body portion 52 of the intermediate leg 5 is substantially the same as the depth dimension of the frame body 6, so that the desk 100 can be used even at the boundary between the top plates 1 that are laterally adjacent to each other. Is configured.

The frame body 6 is formed, for example, by forming a rectangular frame from a pipe material having a square cross section, and connecting the two rectangular frames with their long sides up and down and leaving only the width of the storage space 2. There is. Then, the side panel 4 is fixed to one side surface of each of the two frame bodies 6, the remaining other side surfaces are arranged so as to face each other, the intermediate leg 5 is fixed to the other side surface, and the top plate 1 is removed. The main parts of 100 are connected at their respective opposing faces and have sufficient depth to accommodate cords. The upper surface opening 21 of the storage space 2, which is the upper part of the frame body 6, is openably and closably closed by the duct cover 3, and the front surface thereof is attached with a back plate 61 to cover the cords stored in the storage space 2. It is supposed to be hidden.

In such a structure, each top plate 1 is attached in the order described below. First, the top plate 1 is placed on the leg element FE formed by the side panel 4, the intermediate leg 5, and the frame body 6 with the use end 1a side facing you. At this time, the balance member 71 of each tightening metal fitting 7 is
The other end 71b is lifted and the hook-shaped portion 71
a is below the top plate mounting surface 42b. From this state, when the top plate 1 is pushed toward the non-use end 1b side and is slid, the front engagement hole 1 of the top plate 1 is slid.
The hook-shaped claw 45 is engaged with the shaft 4. After sliding the top plate 1 in this manner, the other end 71b of the balance member 71 is attached to the leg element F.
In order to tighten it to E, the bolt 72 is inserted into the oval through hole 71c and screwed into the nut 42e. By this bolt tightening operation, the balance member 71 rotates in the direction of the non-use end 1b of the top plate 1, and the tip of the hook-shaped portion 71a of the balance member 71 causes the rear edge of the top plate 1 to engage with the rear edge of the rear engagement hole 15. The hook-shaped portion 71a pushes the rear edge 15a of the rear engagement hole 15 toward the non-use end 1b from the state of being in contact with 15a, and is further drawn from the position where the top plate 1 is slid to the non-use end 1b side. When the bolts 72 are completely tightened, the hook-shaped portion 71a stands vertically to fix the top plate 1. In this tightening, the top plate 1 further moves from the sliding position to the side opposite to the use end 1b, so that the hook-shaped claw 45 is locked to the front end portion 14a having the narrow width of the front engagement hole 14, Engagement becomes strong.

After the four corners of the top plate 1 are fixed as described above, the intermediate position of the non-use end 1b of the top plate 1 is fixed by the locking fittings 61. The locking metal fitting 61 is made of sheet metal and has a base 6
A through hole 61b is formed in the center of 1a for fixing, and the base 61
Engaging pieces 61d each having a ¼ circular engaging portion 61c formed at the tip are provided on the left and right of a. The engaging portion 61c of the locking metal fitting 61 is moved and inserted into the slit 16 of the top plate 1 while rotating the engaging piece 61d from the upper side to the lower side,
The base 61a is fastened to the upper surface of the frame body 6. Therefore, the top plate 1 is fixed to the intermediate position on the side of the non-use end 1b while being slightly attracted to the locking piece 61d to the side of the non-use end 1b.

In this way, the mounting of the top plate 1 can be completed without the work of diving under the top plate 1. That is,
For the mounting work, the top plate 1 is placed on the leg element FE, and the non-use end 1
It is completed by sliding to the b side and tightening the tightening metal fitting 7 with the bolt 72. Since the bolt 72 is tightened from the top of the top plate 1, it does not impose an unreasonable posture. On the side of the use end 1a of the top plate 1, the hook-shaped claw 45 firmly engages with the front engaging hole 14, so that the top plate 1 is acted on by the tightening mechanism BM even though the structure is simple. Can be fixed without tightening. Further, not only the anti-use end 1b side of the top plate 1 but also the anti-use end 1b side is fixed in a tensioned state to the anti-use end 1b side, so that rattling in the vertical direction can be prevented. . Further, the intermediate portion of the non-use end 1b of the top plate 1 is provided with a locking fitting 61.
Since the top plate 1 is long, even if the top plate 1 is long, the non-use end 1b does not rattle at the intermediate portion.

The present invention is not limited to the embodiment described above. For example, as the leg element FB, only the two side panels 4, the side panel 4 and the drawer are provided, in addition to the leg element FB configured by the side panel 4, the frame body 6 and the intermediate leg 5 as in the above embodiment. It may be configured with a sleeve portion, and further with two sleeve portions.

Further, the front engaging hole 14 and the hook-shaped pawl 45 which form the slide engaging portion SE, contrary to the above-mentioned embodiment,
The front engagement hole 14 may be formed in the leg element FE, and the hook-shaped claw 45 may be provided on the lower surface of the top plate 1. Alternatively, the front engaging hole 14 is a daruma hole formed by integrally integrating two round holes having different sizes, and the hook-shaped pawl 45 is a stepped pin whose tip portion is formed to have a diameter larger than that of the body portion. It may be configured.

Further, as the tightening metal fitting 7, as shown in FIGS.
As shown in FIG. 2, the upper surface portion 171a of the balance member 171 is pushed by the top plate 1 to rotate, and the hook-shaped portion 171b is engaged with the rear engaging hole 15 of the top plate 1. May be. That is, in this modified example, the tightening member 7
When the balance member 171 is mounted in a predetermined position and the balance member 171 is tilted, the stepped portion 1 of the support member 173 of the tightening member 7
The upper surface portion 171a of the balance member 171 is inclined and exposed at 73a. Since the balance member 171 is attached to the support member 173 in this manner, when the top plate 1 is attached, when the top plate 1 is first pushed into the non-use end 1b side and is slid, the slide movement causes the top to move. While the hook-shaped claw 45 is engaged with the front engagement hole 14 of the plate 1,
The lower edge of the non-use end 1b of the top plate 1 comes into contact with the upper surface portion 171a of the balance member 171 and pushes it down to move the balance member 171.
Stop at about horizontal position. In this state, the hook-shaped portion 171b of the balance member 171 is almost in the rear engaging hole 15 of the top plate 1. After that, if the bolt 72 is inserted into the bolt hole 171c at the rear end of the balance member 171 and tightened, the balance member 171 further rotates and maintains the horizontal position, and at the same time, engages with the rear engaging hole 15 to engage the top plate. 1 is further pulled in the direction of the non-use end 1b to firmly fix the top plate 1. With such a configuration, at the same time as the hook-shaped claw 45 engages with the front engaging hole 14 on the use end 1a side of the top plate 1,
Since the hook-shaped portion 171b of the balance member 171 enters the rear engagement hole 15, the top plate 1 can be temporarily fixed before the balance member 171 is tightened. Besides, the configuration of each unit is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

[0023]

As described above in detail, the present invention fixes the top plate by the slide engaging portion for engaging the top plate and the leg element and the tightening mechanism for tightening the balance member with the screw element. It has a simple structure, but it is possible to reduce the area to be tightened with screw elements, and since the tightening work can be performed from above the top plate, it is not necessary to take an unreasonable posture during work. In addition, since the work place is not limited, the work can be performed with a normal tool, and therefore the work content can be facilitated.
