Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bracket mounting structure suitable for detachably mounting an auxiliary top plate or a shelf plate via a bracket.

[0002]

2. Description of the Related Art When auxiliary top plates or shelves are detachably attached to a base table or wall, recently, hook holes are provided at two positions of the base, and bent hooks are provided in the respective hook holes. A structure has been developed in which the brackets that are held are hooked, and the brackets are horizontally mounted to fix the auxiliary top plate and the like. This kind of thing is easy to install because you only have to hook the bracket to the hook hole.
It is possible to mount various parts other than the auxiliary top plate and the shelf plate without causing the structure of the base body side to be complicated.

[0003]

By the way, in the above-mentioned one, basically, the bent claws of the bracket are inserted into the respective hook holes opened in the same direction, and the bent claws are dropped and engaged. When the auxiliary top plate or the like is lifted and pulled in the direction opposite to the insertion direction, the bracket easily comes off the base body. With this in mind,
There is also considered a structure in which the hook holes are opened in mutually different directions so that the bracket does not immediately come off the base body even when the auxiliary top plate or the like is lifted. However, even in this case, since the engagement between the hook hole and the bent claw is released at least when the auxiliary top plate or the like is lifted, in this state, each bracket receives a single external force such as kicking. The bracket may come off the base body if it is worked or if the auxiliary top plate or the like is shaken strongly.

[0004]

Means for Solving the Problems] To solve the above problems, the present invention is previously provided with a pair of hooks holes opening toward a direction different from each other on the substrate, each full
A plurality of downward bending claws provided at the same pitch as the hook holes are hooked in the hook holes with brackets configured so that they cannot be removed unless tilted, and auxiliary brackets and shelf boards are attached to these brackets. It is intended to prevent the brackets from coming off from the hook holes without providing a dedicated coming-off preventing component.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In a bracket mounting structure according to the present invention, a pair of brackets are hooked in hook holes provided in a pair of bases, respectively, and a member to be supported is fixedly mounted on these brackets. The hook holes provided in each of the bases are provided in a plurality of stages in the vertical direction at a predetermined pitch, and the hook holes provided in one base and the hook holes provided in the other base. When the brackets are opened in different directions from each other and a plurality of downward bending claws provided on the bracket at the same pitch as each hook hole are in the mounting posture in which the bracket is in the upright state, only the lowermost bending claw is projection dimension for the hook hole, fluoride
When the bracket is set to be larger than the hole size and the bracket is tilted along the opening direction of the hook hole, it should be attached to the hook hole of the bending claw located at the bottom.
By setting the projected size to be smaller than the size of the hook hole, each bracket that is hooked in the hook hole and is in the mounting posture is opened from the mounting posture .
It is characterized in that it can be detached from the hook hole only when it is tilted along the direction . Also, a pair of brackets are hooked in the hook holes provided in the pair of bases, and the brackets are fastened to the brackets while the supported members are installed on the brackets. The hook holes are provided in a plurality of stages at a predetermined pitch in the vertical direction, and the hook holes provided in one base body and the hook holes provided in the other base body are opened in mutually different directions, and each hook is provided. a plurality of upwardly bent pawl provided on the bracket holes and the same pitch, when the attachment posture is upright the bracket, the uppermost bent nails only, the projection dimension for the hook hole, fluoride
When the bracket is set to be larger than the hole size and the bracket is tilted along the opening direction of the hook hole, it should be attached to the hook hole of the bending claw located at the top.
By setting the projected size to be smaller than the size of the hook hole, each bracket that is hooked in the hook hole and is in the mounting posture is opened from the mounting posture .
It is also conceivable that the device is configured so that it can be disengaged from the hook hole only when it is tilted along the direction .

According to this structure, since the hook holes are opened in different directions, the brackets hooked in the hook holes respectively are fixed at the time when the supported member is fixed.
Since they are restrained from each other and the disengagement operation from the base body is prohibited, and each bracket is configured so that it cannot be disengaged from the hook hole unless tilted in different directions,
No matter how the supported member is moved, the engagement between the bracket and the hook hole is not released. Therefore, the possibility that the bracket will come off from the hook hole can be made extremely low as compared with the conventional one. Moreover, there is no need for a component for preventing the bracket from coming off the hook hole, and the number of components can be reduced as much as possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a table having a basic structure, and FIG. 2 is an exploded perspective view of the table. This table is provided with a top plate 1 and four legs 2 which form a base body and support the top plate 1. The hook holes 3 are provided on the facing surfaces 2a of the adjacent legs 2, respectively. ing.

More specifically, the top plate 1 is, for example, 1600
It has a square shape in plan view having one side of mm, and two opposite sides are used ends 1a and 1b, respectively. An opening 11 having a rectangular shape in plan view is formed between the two used ends 1a and 1b, that is, in the center of the top plate 1. Each leg 2 is a cylindrical body having an adjuster 21 at its lower end, and its upper end 2b is in contact with the lower surface of the top plate 1. The legs 2 located in the vicinity of the respective used ends 1a, 1b are rigidly connected by a prism-shaped pipe-shaped first horizontal connecting member 22 parallel to the used ends 1a, 1b. Each of them, and the portions near the right ends thereof are rigidly connected by a second horizontal connecting member 23 having a prismatic pipe shape. The first and second horizontal connecting members 22 and 23 are in close contact with the lower surface of the top plate 1, and the horizontal connecting members 22 and 23 and the top plate 1 are fixed to each other by screws (not shown). The adjacent legs 2, specifically, the leg 2 (1) located on the side of one used end 1a and the opposing face 2a of the leg 2 (2) located on the side of the other used end 1b in FIG. , And hook holes 3 are provided respectively. The hook hole 3 of the leg (1) is not shown in the figure. The hook hole 3 provided in each leg 2 penetrates into the internal space of the leg 2, has a vertically elongated shape, and is provided in a plurality of stages at a predetermined pitch in the vertical direction.

Between the intermediate portions of the second horizontal connecting member 23,
An intermediate gutter 25 having a plurality of circular holes 24 is installed. A lid 13 having a circular hole 12 is detachably attached to the opening 11 of the top plate 1. 3 to 7
Shows an example in which the auxiliary top plate 5, which is a supported member, is attached to the table having the above basic structure via the bracket 4.

The auxiliary top plate 5 is arranged so as to be continuous with the left and right side edges of the top plate 1, and the outer edge 5a is curved in a partial arc shape. A mounting recess 51 is provided which is gradually deeper toward the bottom. An insert nut 52 is embedded in the mounting recess 51.
As shown in FIGS. 7 and 8, the bracket 4 has, for example, a base end plate 42 whose front end faces toward the facing leg 2, and a substantially right angle outward from a front end edge 42 a of the base end plate 42. The extension plate 43 that is bent and extended in a horizontal direction and the mounting plate 44 that extends horizontally from the upper edge of the extension end portion of the extension plate 43 are integrally formed by using one sheet metal material.

The base plate 42 has a plurality of downwardly bent claws 41 protruding from the base edge 42b at the same pitch as the hook holes 3. Each bending claw 41 has a base portion 41a that extends horizontally from a base edge 42b of the base plate 42 and an extension portion 41b that bends and extends downward from the base end edge.
Consists of. As will be described later, the upper end outer edge portion 41c of the extending portion 41b, which is the bent portion outer edge, prevents interference with the upper edge of the hook hole 3 when the bending claws 4 are rotated into the hook holes 3 to be inserted and removed. For the purpose and the like, it is formed so as to have a partially arcuate side view. In addition, each bending claw 41 except the lowermost bending claw 41
The vertical dimension H1 of the hook is substantially the same as the vertical dimension hh of the hook hole 3 shown in FIG. Therefore, only the bent claw 41 located at the lowermost position has a vertical dimension H2 larger than the vertical dimension hh of the hook hole 3 so as to be lower than the other bent claws 41 below the extending portion 41b. The extension dimension h2 to the length is set to be long. Further, as shown in FIG. 9, when the bracket 4 is tilted along the opening direction of the hook hole 3 from the mounting posture in the upright state, the bending claws 41 located at the lowermost position are up and down. Direction maximum dimension H3 is the vertical dimension hh of the hook hole 3
It is set to be smaller than. In this way, in order to insert and remove the bent claw 41 located at the lowermost part into the hook hole 3, the bracket 4 must be in a tilted posture in which the bracket 4 is tilted along the opening direction of the hook hole 3. There is.

In order to hook the bracket 4 into the hook hole 3, as shown in FIGS. 9 and 10, first, the lowermost bent claw 41 with the bracket 4 in the inclined posture.
Is inserted into the hook hole 3. Then, the bracket 4 is pivotally erected about the lowermost bent claw 41, and as shown in FIG. 11, each bent claw 41 is inserted into the corresponding hook hole 3 up to its base 41a, and the bracket 4 is fixed. Set to the mounting posture. In this state, the engaging portion K is formed between the extending portion 41b of the lowermost bending claw 41 and the inner wall surface around the hook hole 3, and the engaging portion K makes the bracket 4 tilted. It will not be released unless you do. After that, the bracket 4 is slid downward in that posture, and the extending portion 41b of each bending claw 41 is engaged with the inner wall surface around the hook hole 3, as shown in FIG. In this way, the opposite legs 2
After the brackets 4 each having a target shape in plan view are hooked in the hook holes 3 of the auxiliary top plate 5, the auxiliary top plate 5 is mounted on the mounting plate 44 of each bracket 4, and the mounting plate 44 is mounted in the mounting recess 51 of the auxiliary top plate 5. The auxiliary top plate 5 is fixed by screwing the bolt 46 inserted into the bolt insertion hole 45 of the mounting plate 44 into the insert nut 52 of the auxiliary top plate 5, There is.

In this state, the auxiliary top plate 51 prohibits the approaching motion for pulling out the brackets 4 hooked on the legs 2 facing each other, so that even if the auxiliary top plate 5 is lifted, 4 does not come off from the hook hole 3. In addition, even when the auxiliary top plate 5 is lifted, the engagement between the lowermost bent claw 41 of the bracket 4 and the inner wall surface around the hook hole 3 is not released, so that each bracket 4 can be kicked or the auxiliary top plate 5 can be lifted. Even if the plate 5 is strongly shaken, the bracket 4 becomes very difficult to come off.

Further, according to the structure of the present embodiment, while the lowermost bent claw 41 is engaged with the hook hole 3, the bracket 4 is rotated to the mounting posture standing upright from the inclined posture,
Since the other bending claws 41 are engaged with the hook holes 3, it is not necessary to drop the bracket largely for engagement as in the conventional case. Therefore, the extension dimension h1 of the bent claw 41 excluding the lowermost one to the lower side of the extension portion 41b, that is, the drop dimension, can be made smaller than that in the first embodiment, and the rattling of the bracket 4 in the vertical direction after mounting can be reduced. Can be reduced. Theoretically, as shown in FIG. 13, since the engagement of the lowermost bent claw 41 with the hook hole 3 is ensured, the extension portion 41 b of the bent claw 41 other than the lowermost bent claw 41 is secured. It is also possible to set the downward extension dimension to 0 and fit the bent claws into the hook holes in a substantially tight fit with the bracket 4 hooked in the hook holes 3. By doing so, it is possible to eliminate the vertical rattling of the bracket 4 after mounting. Further, the bending claw 41 that requires the tilting of the bracket 4 when inserting into and removing from the hook hole 3 may be provided at the uppermost position as shown in FIG. 14, not at the lowermost position. In this case, it is preferable to bend the extending portion 41b of the bending claw 41 upward as shown in FIG.

The table equipped with such an auxiliary top plate 5 is preferably used for meetings and the like. In the illustrated embodiment, the top plate 1 and the auxiliary top plate 5 are arranged at the same height position. However, for example, if the bracket 4 is engaged with the lower hook hole 3, the auxiliary top plate 5 is formed. Can be held at a position lower than the top plate 1. When the auxiliary top plate 5 is mounted at a lower position than the top plate 1, it becomes convenient when a keyboard or the like is placed on the auxiliary top plate 5 for work.

The present invention is not limited to the above-mentioned embodiments, but various modifications can be made. For example, hook holes may be provided in two rows on each leg with a phase difference of 90 degrees, and the use ends may be set on all four surfaces of the top plate. In this way, supported members such as auxiliary top plates can be attached to all four surfaces. Further, the hook holes provided in the adjacent legs do not have to be opened opposite to each other as in the above-mentioned embodiment, and the opening direction is not limited as long as they are opened in different directions. . For example, in FIG.
As shown in FIG. 3, hook holes 3 provided in each adjacent leg 2
It is conceivable that the opening direction of is symmetrically set to an angle of about 45 degrees with respect to an imaginary line M parallel to the use edge of the table. Further, the supported member is not limited to the auxiliary top plate and may be a shelf or the like. Further, the base body is not limited to the table, and various types such as a wall body can be applied according to the form of the supported member.

[0020]

As described in detail above, according to the present invention,
Since the pair of hook holes are opened in different directions, the brackets hooked in the respective hook holes are restrained from each other when the supported member is fastened, and the detachment operation from the base body is prohibited. It Since each bracket is configured so that it cannot be disengaged from the hook hole unless it is tilted in at least different directions, no matter how the supported member is moved, it is provided at the same pitch as each hook hole.
Multiple downward bending claws are hooked in the hook holes
It is extremely unlikely that the bracket will come off the hook hole when an unexpected external force such as kicking each bracket by itself is applied, and the engagement between each bracket and the hook hole is not released. it can. That is, according to the present invention, it is possible to make the bracket extremely unlikely to come off without complicating the structure, and it is possible to improve the reliability of attachment of the supported member. In addition, a component for preventing the bracket from coming off the hook hole is not necessary, and the number of components can be reduced as much as possible.

[0021]

[0022]

If the outer edge of the bent portion of the bent claw is formed to have a partially arcuate shape when viewed from the side, it is possible not only to facilitate the insertion and removal of the bent claw but also to make the bent claw substantially in the hook hole as described above. It can be easily fitted tightly.
