Description

[Detailed Description of the Invention] Industrial Application Field The present application relates to a non-slip device that is attached to leg members of furniture such as chairs and tables made of pipes.

Conventional Technology Conventionally, when furniture such as pipe chairs and tables is used in a gymnasium, for example, it is necessary to use an upward-facing top to prevent the furniture from slipping on the floor and to prevent damage to the floor. A non-slip device made of synthetic resin or the like is attached to the lower piece of the leg member having a letter shape.

This anti-slip device is generally installed using drainage holes provided on the lower surface of the lower left and right positions when plating the leg member, and the required conditions are that it is easy to install and operate. At the same time, the structure is such that the anti-slip tool does not separate from the member due to external force after being installed.

By the way, conventionally, a locking protrusion that locks into a drainage hole provided in a lower piece of a leg member is integrally provided at the center of the inner surface of a fitting member made of synthetic resin and having a C-shaped cross section. For example, a non-slip device made of
It is publicly known in Publication No. 142513 to Publication No. 43900 of 1983.

Problems to be Solved by the Invention However, in all of the conventionally known devices, it is troublesome to fit the anti-slip device onto the lower piece of the leg member, and when the anti-slip device is in the fitted state, the upper part of the fitting member is Since the seat is left open, the user of the chair often hooks the heel of the shoe onto the open end of the fitting.
There was a fear that a downward external force would be applied to the fitting member, and that the anti-slip device would come off from the leg member.

Means for Solving the Problems Therefore, in order to solve the disadvantages of the conventional ones, the present application forms a serrated tooth portion on one outer surface of a band-shaped roll, and also forms a serrated tooth portion on the other end of the roll. A locking portion having a hole and a locking claw provided on the upper inner surface thereof and locking with the teeth in the unwinding direction of the winding body is integrally provided, and a leg member is provided on the inner surface of the winding body. It is made of synthetic resin and is provided with an engaging protrusion that engages with a hole in the hole, and preferably has a locking pawl that slopes downward toward the front.

Function: When installing, the engaging protrusion is engaged with the drainage hole in the lower piece of the leg member.
While winding the roll around the leg member, the tip thereof is inserted into the insertion hole of the locking part.

Then, in the insertion (winding) direction, the tip of the locking pawl slides on the inclined surface of the tooth and does not lock, so it can be easily tightened, and if the winding operation is stopped in this state, The locking pawl locks with the tooth portion in the unwinding direction, and the roll is held in a tightened state at the position of the drain hole of the leg member.

Note that the excess end portion of the winding body protruding from the locking portion is cut off using a necessary tool.

Embodiment Hereinafter, the embodiment of the present application will be described in detail based on the drawings. 1 is a band-shaped roll, the tip of which is formed in a slightly tapered shape, and the outer surface of the tip portion has teeth with a sawtooth cross section. A plurality of sections 2 are provided. Reference numeral 3 denotes a frame-shaped locking part integrally provided at the rear end of the roll 1, which includes an insertion hole 4 through which the roll 1 can be inserted, and is provided at the upper part of the inner surface of the insertion hole 4; In the winding direction in which the roll 1 is inserted into the insertion hole 4, it does not engage the teeth 2, but in the unwinding direction,
A locking pawl 5 that locks with the tooth portion 2 is provided, and the locking pawl 5 is inclined forward and downward through a notch 6 so as to bite in the rewinding direction. 7 is leg member 1
This is an engaging protrusion that engages with a drainage hole 11 provided in the lower piece of the 0.

Therefore, when installing, the roll 1 is wound around the leg member 10 while the engaging protrusion 7 is engaged with the drain hole 11 provided in the lower piece of the leg member 10, and the tip of the roll 1 is wound around the leg member 10. It is inserted into the insertion hole 4 of the locking part 3.
Then, in the insertion (winding) direction, the tip of the locking pawl 5 slides on the inclined surface of the toothed part 2 and does not lock, so the roll 1 can be easily tightened. When the winding operation is stopped, the locking pawl 5 locks with the tooth portion 2 in the unwinding direction, and the roll 1 is locked with the leg member 1.
The tightened state is maintained at the position of the drain hole 11 at 0.

Note that the extra tip portion of the roll 1 protruding from the locking portion 3 (the portion indicated by the imaginary line in FIG. 1) is cut off with a tool such as scissors.

In addition, when replacing the slipper due to wear and tear, insert the tip of a tool such as a screwdriver into the insertion hole 4 and press the locking pawl 5 upward to release the lock from the tooth portion 2. It is something to do.

Effects of the invention Since the present application is constructed as described above, each operation of engaging the engaging protrusion with the hole of the leg member, winding the winding body around the leg member, and tightening the winding body can be performed extremely easily. In addition, it can be used with leg members of different thicknesses, and because the structure surrounds the outer periphery of the leg member, it can be prevented from falling off by hooking the heel of the shoe and opening the opening of the non-slip device. It also eliminates the fear of
Furthermore, a locking claw is provided at the upper part of the inner surface of the insertion hole, so
It has the advantage that the locking pawl can be operated from the outside to release the locking between the locking pawl and the teeth, which is convenient when replacing the slipper.
