Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention has a frame that is ideal for electric kotatsu and whose height can be adjusted. relating to leg devices.

0002

[Conventional technology]

Change the height of the frame used as a table in response to recent lifestyle changes A device that does this is proposed in Japanese Utility Model Application Publication No. 57-188049. Like this In the prior art, removable spacers are inserted between the frame and each script body. Therefore, when not using the spacers, it is difficult to find a place to put the four spacers, and if you leave them in the living room. There is a risk of the user tripping and falling or being injured by the spacer screws. there were.

0003

[Problem that the idea aims to solve]

This invention allows the connecting legs that change the height of the frame to be fixed and stored on the frame side when not in use. It is something that

0004

[Means to solve the problem]

The present invention includes a plurality of crosspieces, a mounting bracket that connects adjacent ends of the crosspieces, and a mounting bracket that connects adjacent ends of the crosspieces. Consists of a base leg fixed to a mounting bracket and a connecting leg removably connected to the bottom of the base leg. and a mounting part is formed on the mounting bracket to fix the joint leg removed from the base leg. It is.

[0005] The lower end of the joint leg is in the same position as the lower end of the base leg when fixed to the mounting part. The length dimensions are set so that

[0006] The connecting leg has at least two pieces having the same length, and each connecting leg is attached to the mounting portion. The base leg is located between the connecting legs when the base leg is fixed to the base leg.

[0007]

[Effect]

When making the frame higher, connect the connecting leg to the bottom of the base leg, and when making the frame lower, connect the connecting leg to the bottom of the base leg. Remove the connecting leg from the base leg and secure it to the mounting bracket on the frame side to store the connecting leg.

[0008] When using the frame as a low table by fixing the connecting legs to the mounting part of the mounting bracket. is set so that the lower end of the connecting leg and the lower end of the base leg are in the same position, and Increase the strength of the legs under the load.

[0009] At least two connecting legs have the same length, and when each connecting leg is fixed to the mounting part, The base legs are positioned between the joint legs, so that the legs are not affected by external forces from the left and right directions of the frame. increase the strength of

【Example】

Embodiments of the present invention will be described based on the drawings. (1) is multiple crosspieces (2) (2) (2) (2) and a plurality of beams (20) (20) ( 20) A rectangular frame consisting of (20), (3) (3) (3) (3) is the frame (1 ) and the adjacent ends (2) of the crosspieces (2) (2) (2) (2) It is a mounting bracket that connects a) and (2b), and has a screw hole on the bottom as shown in Figure 1. It has mounting portions (4) (4) (hereinafter referred to as screw holes). (5)(5)(5)( 5) is between the adjacent ends (2a) and (2b) of the crosspiece, and the center thereof is the screw The base leg fits into the notch (6) located between the holes (4) (4), and there is a screw insertion hole at the bottom end. (7) and is fixed to the mounting bracket (3) with bolts (8).

[0011] (9) ... is the length dimension that is detachably connected to the base leg (5) (5) (5) (5). are the same two connecting legs, with a screw (10) at the upper end and a screw insertion hole (11) at the lower end. The intermediate joint leg (12) has a screw inserted into the screw insertion hole (11) of the intermediate joint leg at the upper end. (13) and a lower connecting leg (14). The intermediate joint leg (12) and the bottom The length of each of the joint legs (14) is set to be the same as the length of the base leg (5). ing.

0012 (15) is the center formed by the beams (20) (20) (20) (20) This is a heater unit attached to the unit.

[0013] Next, the case of changing the height of the frame (1) will be described. Heat the frame (1) to the highest temperature. When using it as a wind table, attach the screw (10) of the intermediate joint leg (12) to the base leg (5). ) into the screw insertion hole (7), and screw the screw (13) of the lower joint leg (14) into the intermediate joint. It is screwed and fixed into the screw insertion hole (11) of the leg (12). (See Figure 2) When using the frame (1) as an electric kotatsu with a slightly higher height, attach the lower leg (14 ) into the screw insertion hole (7) of the base leg (5). At this time, When the intermediate joint leg (12) is in use, insert its screw (10) into any of the mounting brackets (3). Screw it into one screw hole (4) (4) and store it.

[0014] When using the frame (1) as a low table with a lower frame, use the intermediate joint legs (12). and lower connecting leg (14) respectively, and insert them into the screw holes (4) (4) of the mounting bracket (3). Screw together and store. In this state, the base leg (5) is connected to the intermediate leg (12) and the lower leg (1). 4), and there is a heavy load on the frame (1) and the top surface of the frame. Even if (humans, OA equipment) are placed on the frame (1), the base leg (5) and the intermediate joint leg ( 12) and the lower base leg (14), causing the legs to wobble. Never.

[0015] Also, when using it as a low table, external force is applied to the frame (1) in the left and right direction. Even if the base leg (5), intermediate joint leg (12) and lower joint leg (14) are unitized. and reinforce each other.

[0016] This means that when using the frame (1) as a low table, its height This makes it easier for people (especially children) to rest on the legs than when it is high. This is because strength is required.

[0017] In addition, in this example, the attachment part of the connecting leg is a screw hole, but from the point of view of storing the connecting leg when not in use, It does not need to be a screw hole, as long as it can be easily temporarily fastened.

[0018]

[Effect of the idea]

As described above, the present invention has a mounting part for connecting legs formed in the mounting bracket that connects and fixes the bars. This makes it clear where to store the legs when they are not in use, and prevents them from being lost or injured. There is no danger of this happening. In addition, the connecting legs fixed when not in use can be attached to the mounting bracket. Since it is fixed, it will not get in the way.

[0019] The extension leg should be long enough so that its lower end is in the same position as the lower end of the base leg when it is fixed to the mounting part. Because the dimensions are set, the lower ends of the connecting legs and base legs are in contact with the floor and the load from above the frame is Strength is improved as a supporting leg.

[0020] The connecting legs have at least two of the same length, and when not in use, each When the connecting legs are fixed to the mounting part, the base legs are located between the connecting legs, so it cannot be seen from above the frame. The joint legs and base legs act as a unit, not only against the load but also against external forces from the lateral direction. reinforced to increase strength and prevent rattling of the frame.
