BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame device such as a laboratory table, and more specifically, as a frame of a laboratory table or a work table similar to it, a leg frame of a display stand, a storage shelf, a housing, etc. The present invention relates to a frame device that can be used.

[0002]

2. Description of the Related Art Conventionally, various structures for connecting a leg member and a lateral member have been provided such as screwing. For example, Japanese Utility Model Publication No. 40-7465 discloses a structure in which a post as a leg member is connected to a shelf bracket as a lateral member. That is, a vertically long engaging hole is formed in the support column, an engaging piece is projected from the edge of the shelf receiving bracket, and the engaging piece is fitted and locked in the engaging hole. This is a structure in which the base portion is fitted in the engagement hole so that the vertical movement is reduced, and the tip end portion of the engagement piece is locked to the hole edge portion in the engagement hole.

Further, in Japanese Patent Publication No. 61-16821, a slot is formed on the side surfaces of a pair of columns that are erected at a predetermined interval so as to face each other, and a fitting member for fitting the slot to the edge of a horizontal member. A downward hook to be stopped and a fixing tab projecting upward from the hook are projected upward, and with the hook fitted and locked in the slot, the fixing tab is bent to abut the upper edge of the slot, and a horizontal member is provided between the columns. A structure for retaining and connecting is disclosed.

However, the connection structures described in any of the publications are intended to complete the connection by stopping the leg member and the lateral member at only one connecting part, and in the former case, separate connection It requires a lifting plate to be structurally complicated, and in the latter case, laborious work such as bending the fixing tab is required.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned situation, the present invention is to solve a leg frame or the like of a laboratory table by simply and firmly connecting a plurality of leg members at a predetermined interval. The point is to provide a frame device such as a laboratory table that can be configured.

[0006]

In order to solve the above-mentioned problems, the present invention forms a slit hole in the side plates facing each other of a pair of leg members arranged at a predetermined interval, and at the same time, A fitting piece having a cross-sectional shape that closely fits in the slit hole is projectingly provided on both end edges, and a hook piece that engages with a hole edge portion in the slit hole is extended to the fitting piece to form a connecting portion. A test bench in which the connecting portions of the lateral members are fitted and locked in the slit holes of the leg members and the two leg members are arranged in parallel, and the other portions of the both leg members are connected by a single or a plurality of connecting members. Etc. configured a frame device.

Here, the leg member has a lateral rod fixed between the upper and lower sides of a pair of front and rear leg rods standing up and down, and the slit hole is formed at the upper end of the side plate of the front leg rod. It is a preferred embodiment that the rear leg rods are connected to each other by the connecting member.

It is also preferable that the slit holes are formed at the same positions inside and outside of both side plates of the leg member, and two or more leg members are sequentially laterally connected to each other by a connecting member.

[0009]

In the frame device of the present invention having the above-mentioned contents, such as a laboratory table, the leg member and the lateral member are inclined so that the hook pieces are oriented within an acute angle, and the connecting member of the lateral member is connected. After inserting from the hook piece into the slit hole formed in the side plate of the leg member, the fitting member of the connecting portion is tightly fitted into the slit hole by returning the leg member and the lateral member at a right angle,
The hook piece is locked at the hole edge in the slit hole, the horizontal member is connected between the two leg members, and the two leg members are arranged in parallel. One or a plurality of connecting members are connected, and both leg members are integrated with the lateral member by the connecting member. In this state, since the parallel state of both leg members is maintained and the fitting piece is tightly fitted in the slit hole, the hook piece of the connecting portion does not come off from the slit hole.

Further, the leg member has a lateral rod fixed between the upper and lower sides of a pair of front and rear leg rods standing up and down, and the slit hole is formed at an upper end portion of a side plate of the front leg rod. Yes,
In the case where the rear leg rods are connected to each other by the connecting member, the leg members are strong, and when the top plate is placed and fixed on the upper ends of both leg members, a foot is placed between the two leg members below the top plate. The receiving space is formed.
