FIG.

The bottom surface 3 of the housing device 3 having a width smaller than the height.
a is provided with casters 3b and adjusters 3c near four corners. The housing device 3 is of a type that is disposed adjacent to either the left or right of the desk 5, and is located on the right in this example.

The mechanism comprises a leg receiver 1 attached to the lower surface 3a of the housing device and a leg member 2 engaged with the leg receiver 1. The leg receiver 1 is provided at the bottom of the device. Each of the leg receivers 1 is fixed near the four corners of the lower surface 3a, and each of the leg receivers 1 has a lower groove 1a and an upper groove 1c forming a substantially horizontal groove 1b for inserting and engaging a part of the leg 2 from the outside. This groove upper piece 1c
And a horizontal elastic piece fixing portion 1e located above the
One end of the leg material pressing elastic piece 1f is fixed to the fixing portion 1e, and the other end, that is, the free end, extends obliquely below the forward (rightward in the figure) extension of the groove 1b. A vertical mounting piece 1g fixes these to the housing lower surface.

The leg member 2 has a slightly elongated plate shape and is of a size that can be held by one hand, and has an L-shaped upper part at the upper end of the leg member body 2d and a projecting portion that extends at a right angle thereto. It has a tongue piece 2a.

The tip of the upper groove piece 1c of the leg receiver 1 is the lower groove piece 1a.
It protrudes from the tip. This is for facilitating the insertion of the leg material 2.

The free end of the leg pressing elastic piece 1e in the leg receiver 1 has a small, substantially semicircular cross section that projects downward. This is because the leg member 2 is pressed to easily and reliably insert and lock.

The thickness t ₁ of the tip of the body of the leg material 2 is smaller than the gap t ₂ between the lower end of the side of the housing device and the floor. The length l ₁ of the leading end protruding portion of the L-shaped tongue piece 2a is shorter than the distance l ₂ from the leading end of the groove lower piece 1a to the inside of the opposing housing device. This is because the first entrance is possible.

The length l ₁ is defined by the distance between the groove bottom 1d and the groove upper piece 1c.
Is slightly longer than the length to the tip. This is for the purpose of appropriately setting the positional relationship to be brought into contact with the leg material pressing elastic piece 1f after locking.

The lower end 2e of the tip of the leg material main body is chamfered to facilitate turning and insertion of the leg material.

A mark 3e indicating the leg material insertion position is provided at the lower end of each side surface of the apparatus main body so as to facilitate insertion in a comfortable posture.

Next, the operation of this mechanism will be described.

After the leg member 2 is slanted and inserted from the gap between the lower end of the side of the housing and the floor at the mark 3e, the direction is changed horizontally. Then, the leg support 1 and the leg 2, particularly the elastic piece 1 f of the leg support 1 and the L-shaped tongue 2 a of the leg 2 abut against each other,
The leg pressing elastic piece 1f is deformed upward. The L-shaped tongue 2a of the leg member 2 has the height of the groove 1b. Since the elastic piece 1f presses the L-shaped tongue 2a from the rear, the tongue 2a is inserted into the groove 1b, and the tip of the tongue 2a reaches the groove bottom 1d. In particular, the elastic piece 1f has a shape having a semicircular protrusion at the tip end thereof, and together with the elasticity of the elastic piece 1f, the pressing efficiency is good and the automatic locking state is established after the pressing. Thus, this mechanism can be said to be a one-touch lock system.

[0027]

As described above, according to the present invention, the groove and the leg pressing elastic piece are provided in an appropriate shape and position on the leg receiving member attached to the bottom lower surface of the floor-standing device, and the tip of the leg member is provided. By making the shape of the L-shaped tongue attached to the part and the tip part appropriate, the pressing elastic piece can easily press, insert and lock the L-shaped tongue into the groove, and release the lock, The pull-out of the leg material can also be done quickly, that is, equipped with a one-touch lock method, and there is no need for the troublesome work of screwing work, and there is no risk of damage in case of accidental collision from outside with the leg material after locking, There is an effect that it is possible to provide a fall prevention mechanism for a floor-standing device.
