Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an upper crosspiece opening/closing device of a steel pipe organizing frame for organizing and storing materials such as steel pipes, rods, and pipes for construction.

[Problems to be solved by conventional techniques and ideas]

Conventionally, there are various types of steel pipe organizing frames on the market, but all of them employ a method in which the upper crosspiece is opened, the steel pipes are thrown in, and the upper crosspiece is closed, but they are often handled roughly. , a mechanism that is easy to open and close and is robust is desired.

The present invention proposes an upper crosspiece opening/closing device for a steel pipe arrangement frame that solves this problem.

[Means to solve the problem]

The gist of the present invention will be explained with reference to the accompanying drawings.

In an upper crosspiece opening/closing device for a steel pipe organizing frame A in which the upper crosspiece 1 can be opened and closed and two rectangular frames a in which a plurality of steel pipes 2 can be placed and stored are arranged side by side, the base end 1 of the upper crosspiece 1 has a channel-like cross section. The shaft rod 4 installed on the vertical crosspiece 3' is pivotally attached to the upper part of the vertical crosspiece 3', and the shaft rod 4' is installed on the tip 1'' of the upper crosspiece 1 which is fitted on the upper part of the vertical crosspiece 3'. A handle shaft 5 is installed below the shaft 4' by cutting off the upper outer half of the shaft so that the shaft 4' can be lowered. The handle 6 is formed so that it can be rotated outwardly through the handle 6, and a locking plate shaft 8 is provided at the lower side of the handle 6. Slides freely and attaches freely.
A locking plate 10 whose intermediate portion is pivotally connected to the handle shaft rod 5 is attached to the handle 6, the upper part of the handle 6 is cut off to make the tip of the locking plate 10 protrude, and a shaft is attached to this protruding tip 10'. The engagement groove 11 that engages with the rod 4' is opened outward, and the shape of the top of the locking plate 10 is changed so that the protruding tip 1 of the locking plate 10 when the shaft rod 4' collides with the locking plate 10.
This invention relates to an upper crosspiece opening/closing device for a steel pipe organizing frame, characterized in that 0' is provided in a shape 10'' that is inclined inward.

[Effect]

In the closed state shown in FIG. 3, hold the handle 6 and rotate it outward so that the handle shaft 5 moves to the left end of the L-shaped long window 7, and the locking plate 10 will also be moved by the locking plate shaft 8. Rotate outward together with the handle 6,
The engagement groove 11 of the locking plate 10 is disengaged from the shaft rod 4', and the upper crosspiece 1 can be opened. At this time, the locking plate 1
The presence of the oblique window 9 allows the handle 6 to move up and down.

In this state, the upper crosspiece 1 is pulled up and opened, but the handle 6 returns to its original state due to its own weight.

When closing the upper crosspiece 1, when the tip 1'' of the upper crosspiece 1 falls onto the upper part of the vertical crosspiece 3', the shaft rod 4 engages the locking plate 10.
When the locking plate 10 collides with the shape 10'', the locking plate 10 tilts inward and automatically pushes the shaft rod 4' into the engagement groove 11, and the handle 6 maintains the initial locking state.

〔Example〕

The illustrated handle 6 is formed into a two-piece structure of a folded type, with a locking plate 10 interposed between them.
The figure shows a case where positioning rollers 12 are arranged on the left and right sides.

In the figure, reference numeral 13 denotes an outwardly directed notch groove 1 provided in the upper part of the vertical bar 3 that engages the shaft rod 4 in a slightly loose state.
4 is a pedestal.

[Effect of idea]

Since the present invention is configured as described above, the upper crosspiece can be opened and closed by pulling the handle outward, and when the handle is released, it returns to its original state, and in that state, it is automatically locked by simply dropping the upper crosspiece. This is an extremely easy-to-operate and convenient upper crosspiece opening/closing device for steel pipe organizing frames.

In addition, the opening and closing operations are performed accurately, and the device has excellent practicality, as it can be used as a sturdy upper crosspiece opening and closing device for steel pipe organizing frames that can be used for durability even if it is roughly handled.
