Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is suitably applied to a case where a board having both sides used is attached to a front surface of a panel provided with hook holes along a joint bottom. It relates to a board mounting structure.

[Prior Art] For example, the partition, which is a type of panel that has greatly developed in the recent office revolution, divides a large one-floor office for each work content, or creates a desk space where the office space can be viewed from the surrounding space. It can be used for a variety of purposes, such as shielding. Among them, hook holes are provided in the vertical direction of the pillars that form the skeleton of the partition, and those that open the hook holes at the joint bottom of the partition use the hook holes to remove blackboards, bulletin boards, whiteboards, etc. Since it can be hooked and the hook hole itself can be concealed in the bottom of the joint, it is highly regarded as an extremely avant-garde office furniture item in recent years.

[Problems to be Solved by the Invention] By the way, it is desired that the above-mentioned blackboard, bulletin board, whiteboard, and the like have as large a use area as possible for the purpose of use. However, for example, partitions that partition the periphery of the desk are not so tall, the mounting space for the board is limited, and it is often not possible to secure a sufficiently satisfactory use range. Further, although there is a case where it is desired to store the described contents, the posted matter, etc. for a certain period of time, the conventional board has a disadvantage that the board cannot be used for other purposes during that period. Furthermore, when entering a room outside the company, etc., there may be cases where it is desired to temporarily conceal the contents.
In the conventional board, it is time-consuming to completely erase the contents of the description and to restore it again. Furthermore, even if it is desired to selectively use a blackboard, a bulletin board, or a whiteboard, it is conventionally difficult to simultaneously attach a plurality of types of boards to a partition because of the above-mentioned restrictions on the installation space.

On the other hand, it can be considered as an effective means to use both surfaces of the board as the surfaces to be used, and to turn the surfaces to be used so that either surface can be selectively used. However, simply fixing the metal fittings on the left and right edges of the board and hooking the metal fittings in the hook holes, when replacing the use surface, remove the board together with the metal fittings from the hook holes, turn over the use surface, and hook again. An operation such as mounting it in the hole is required. For this reason, when the top plate or the like projects from the lower front side of the board, the board must be manually engaged and disengaged with respect to the hook hole in a posture of overcoming the top plate, which is extremely difficult. You will be forced to work. In addition, when performing such work, if the space on the front side of the board is infringed by articles etc. placed on the top plate, those articles etc. must be removed before use. It becomes impossible to replace the surface. For this reason, there is a high possibility that a simple mounting structure will not provide sufficient practicality.

The present invention has been made in view of such a problem, it is possible to attach a board having both sides of the use surface to the panel, and further, it is possible to replace the use surface with a simple operation. Moreover, it is an object of the present invention to provide a board mounting structure in which replacement work is not inconvenient even if the front space of the panel is occupied by an article or the like.

[Means for Solving the Problems] The present invention employs the following structure to achieve the above object.

That is, the board mounting structure according to the present invention is such that, when a board having both sides of the use surface is mounted on the front surface of the panel having the hook holes along the joint bottom through the lifting support, the board is surrounded by the outer edge. It is configured such that it is supported in a reversible manner on the frame body, and the elevating and lowering support body is capable of vertically slidably supporting both left and right frame portions of the frame body while being mounted in the hook holes. .

As a specific embodiment for supporting the frame body on the elevating / lowering support body, a T which expands to the back side in the left and right frame portions of the frame body
In addition to the ridges, the elevator support is provided with a U-shaped rail that opens to the front side, and the rails of the elevator support are engaged with the ridges of the frame body, or both left and right sides of the frame body. The frame body is provided with a U-shaped rail opening to the rear side, and the elevating support body is provided with a T-shaped ridge extending to the front side, and the rail of the frame body is engaged with the ridge of the elevating support body. Those that have been made suitable.

In order to prevent the lifting / lowering support from easily falling out of the hook hole after the frame has performed the above-described sliding operation, the lifting / lowering support may be engaged with the hook hole by a pivoting operation. It is effective to include a claw and a lower downward claw that can be engaged with another hook hole by a pressing operation after the upward claw is engaged with the hook hole.

In order to use the board supported in this way functionally, select one or two of the three types of paint finish, enamel finish, and bulletin board specifications on the front and back sides of the board. It is desirable to adopt it.

As a mode in which the board mounting structure of the present invention is particularly effective, there is a case where the top plate is held on the front surface of the panel below the board mounting position through the foot hole.

[Operation] With such a board mounting structure, in a normal mounting state, the frame body is supported by the left and right side frame portions by the elevating and lowering support bodies, and the board accommodated in this frame body has its use surface on the panel surface. Since it is polymerized, it becomes possible to utilize the front side use surface. Also, when the frame is slid upward together with the board from its use position and lifted to a position where the reversing operation of the board in the frame does not interfere with the panel, a pressing force in the surface direction is applied to the board. , It is possible to switch the back side. Then, when the frame body is slid to the original position while being guided and held so as not to drop together with the board due to its own weight, it becomes possible to utilize the use surface that is newly exposed to the front side.

[Embodiment] A practical example of the present invention will be described below with reference to the drawings.

Panel 1 to which board mounting structure of this embodiment is applied
Is generally called a partition. As shown in FIGS. 1 and 2, joints 13 are formed in each adjacent gap of a plurality of surface materials 12 attached via columns 11, and Hook holes 14 are formed in the front surface 11a of the column, which is the bottom of the joint, along the up-down direction, and the top plate 5 is held in advance downward by utilizing these hook holes 14. Then, the board 3 having both surfaces as the use surfaces 31 and 32 is attached to the front surface of the panel 1 through a pair of left and right support members 2.

The board 3 is, for example, a blackboard whose both surfaces 31 and 32 are used for painting, and is accommodated in the inner periphery of the frame body 4 surrounding the outer edge thereof as shown in FIGS. 1 and 3 to 5. The left and right side edge central portions 33 are pivotally attached to the side frame portions 41 of the frame body 4 via the pins 34 in a reversible manner. Then, the side frame portion 41 of the frame body 4
A ridge 42 is fixedly provided on the back surface of the. The ridge 42 has a T-shaped cross section having an enlarged portion 42a on the back side, extends vertically along the side frame 41, and has a lower end 42b lower than the lower frame 43 of the frame 4. It extends downward.

As shown in FIG. 1 and FIG. 6 to FIG. 8, the lifting support 2 includes an upper upward pawl 22 provided on the upper end of a vertical plate portion 24 and lower downward pawls 23, 24 provided below the upper upward pawl 22. , 25, and by mounting the claws 22, 23, 24, 25 in the hook holes 14, the vertical plate portion 21 can be fixed in a state of protruding to the front side of the joint 13. I have to. Then, the rail 2 is biased to the left or right of the front end face 21a of the vertical plate portion 21.
6 is rigidly connected. This rail 26 has an opening 26a on the front side.
It has a U-shaped cross section, and is arranged inside each of the left and right vertical plate portions 21 as shown in FIG. 9 in use. A position where the lower end 42b of the protrusion 42 abuts on the top plate 5 by engaging the expanding portion 42a of the protrusion 42 of the frame body 4 from the upper end as shown by an imaginary line and pushing it downward. In the state of FIG. 1, the frame 4 can be held on the panel 1 in a vertically slidable state.

Note that the claws 22, 23, 24, 25 of the lifting support 2 are provided with a retaining measure to prevent the lifting support 2 from falling off when the frame 4 performs such a sliding operation. There is.
More specifically, the upward claw 22 has a neck 22 as shown in FIG.
When a circular arc A having a radius corresponding to the vertical dimension of the hook hole 14 is drawn with the upper edge 22a _{1 of the a} as a fulcrum, the shape and dimensions are set so that the tip portion 22b fits within the circular arc A. . Then, as shown in FIG. 10, with the lower end of the elevating support 2 being tilted so as to be lifted to the front side,
Insert 22 into the desired hook hole 14
By bringing the upper edge 22a ₁ of the neck portion 22a of the 22 into contact with the upper edge 14a of the hook hole 14 and rotating it to a vertical posture, all the claws 22, 23, 24, 25 are placed in the corresponding hook holes 14. Can be inserted into the upper and lower supports 2 after the nails are inserted.
By pushing down the downward claws 23, 24,
All of the 25 can be hooked on the lower edge 14b of the corresponding hook hole 14. At this time, the upper edge 22b ₁ of the tip end portion 22b of the upward claw 22 is set to be positioned higher than the upper edge 14a of the corresponding hook hole 14.

In such a claw structure, the downward claws 23, 24, 25 can be disengaged from the hook holes 14 when the lifting force is temporarily applied to the lift support 2 by sliding the frame body 4 upward. However, the upward claw 22 is more deeply engaged with the upper edge 1a of the hook hole 14 to make it difficult to pull them out to both sides of the surface, and at the moment when the lifting force disappears. , The downward claw 23 due to the moment caused by gravity, etc.
Apply a force to push 24, 25 into the hook hole 14,
It will return to the original hanging state. Therefore, in order to remove the lifting support 2 from the support 11 of the panel 1, after the lifting support 2 is once lifted up, the lower end of the lifting support 2 is rotated in the direction of lifting to the front side, and the upward claw 22 is hooked. Hole 14
It becomes impossible except by pulling it out from the machine, and it can be accompanied by an effective retaining effect.

With such a board mounting structure, in the normal mounting state shown in FIG. 1, the frame body 4 has the left and right side frame portions 41 supported by the elevating and lowering support body 2, and the board 3 housed in the frame body 4 is supported. Causes the use surfaces 31, 32 to be superposed on the panel surface S,
It becomes possible to use the use surface 31 (32) on the front side.
Further, from this position, the frame body 4 is slid upward together with the board 3 so that the reversing operation of the board 3 in the frame body 4 does not interfere with the panel 1 and the lower end 42b of the ridge 42 is completely removed from the rail 26. When the board 3 is lifted to a position (see FIG. 11) where it will not be pulled out, a pressing force in the surface direction is applied to the board 3, so that the front and back surfaces 31 and 32 can be exchanged. Then, when the frame body 4 is slid to the original position while being guided and held so that it does not drop together with the board 3 due to its own weight, the use surface 32 newly flipped over to the front surface side.
It becomes possible to use (31).

As a result, although the mounting space for the panel 3 is the same as the conventional one, the usable area of the blackboard can be doubled, and in particular, as shown in the drawing, the top plate 5 and the like are mounted below the boat mounting position and the board 3 is mounted. It can be extremely useful if the mounting space is severely constrained. In addition, even if you want to retain the description for a certain period of time, this item can be described by making its surface 31 (32) on the back side and the other surface 32 (31) on the front side. Other descriptions can be made without erasing the contents, and the function of the board 3 can be enhanced.
Further, such a structure can be effectively used for temporarily concealing the described contents. Further, with such a reversing operation, even when the front space of the panel 1 is invaded by an article or the like placed on the top plate 5, the replacement work is not inconvenient, and the board 3 is It becomes possible to effectively improve the practicality.

The present invention is not limited to the above embodiment. For example, U-shaped rails that open to the rear side are provided on the left and right frame portions of the frame body, and a T-shaped ridge that widens to the front side is provided on the elevation support body. The rails of the frame may be engaged with.
In addition, it is of course possible to use both surfaces as an enameled whiteboard or as a bulletin board. Further, the function can be extended by adopting a form in which both use surfaces can be used in a combination of a blackboard and a bulletin board, a whiteboard and a bulletin board, or a combination of a blackboard and a whiteboard. Furthermore, it goes without saying that this board mounting structure can be applied to panels other than partitions that partition the periphery of a desk. In addition, the cross-sectional shape of each part is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

EFFECT OF THE INVENTION According to the board mounting structure of the present invention, it is possible to mount a board having both surfaces to be used on the front surface of the panel provided with the hook holes along the joint bottom through the elevating support, and moreover, the board. It is possible to complete the replacement very easily by simply performing the simple operation of sliding the board with the frame upwards, flipping the board inside the frame, and returning it to its original state. Even when the space is invaded by an article or the like, there is an excellent effect that the practicality of the board can be effectively enhanced because the reversing operation is not hindered.
