Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a non-slip device attached to a pipe leg provided on the bottom of furniture such as a desk or chair, or a floor-standing object such as a rack for audio equipment. This invention relates to a non-slip pipe leg that is easy to attach to the pipe leg and provides stable and strong attachment.

[Prior art]

A non-slip material made of a flexible material is used as a cushioning member for the pipe leg of the floor-mounted pipe as described above, and is wound around the pipe leg to prevent slippage between the pipe leg and the floor surface and to obtain stable fixation. Its use is already well known in the art. In addition, when attaching such a non-slip device to a pipe leg, various types of devices have been proposed that have a tightening structure for the pipe circumferential surface. For example, Utility Model Application Publication No. 56-69053 discloses a non-slip device that is fixed to a band-shaped non-slip device. A stepped portion and an engaging cylinder portion are provided,
A device has been disclosed in which the anti-slip is tightened and attached by winding the anti-slip around the pipe leg and then inserting and engaging the locking stepped portion into the engaging cylinder portion. No. 105244 discloses a method for tightening the cushion member around the pipe leg by wrapping the cushion member around the pipe leg and inserting C-shaped retainers into hook-shaped grooves formed on both sides of the cut portion of the cushion member. What has been done is disclosed.

〔Problems to be solved〕

However, in the former type, the protrusion from the band-shaped non-slip is inserted into a hole drilled in the pipe leg, so that the non-slip is securely fixed around the pipe leg. However, it is impossible to separate the interrelationship between the pipe legs and the anti-slip parts in manufacturing, and there is also the problem that requiring holes to be drilled in the pipe legs is troublesome in terms of man-hours. . Furthermore, the latter type is inconvenient because the cushion member and the C-shaped retainer are separate parts, and there is also the inconvenience that the C-shaped retainer cannot be easily inserted into the hook-shaped groove formed in the cut portion of the cushion member. Additionally, there is the problem that the liner deforms during use and becomes difficult to remove for replacement. Therefore, it is an object of the present invention to solve such problems and provide a non-slip pipe leg that simplifies installation, has excellent fixing properties, and is convenient for handling as it is formed as a single component. It is something to do.

[Means of solution and action]

That is, according to the present invention, the outer surface of a soft annular body having an inner diameter approximately corresponding to the diameter of the pipe leg is formed into an uneven anti-slip surface, and is a non-slip device that is attached to a pipe leg of a floor-standing object. A main body member cut in the axial direction so as to be expandable; a curved frame-shaped clamp actuator made of a hard or semi-hard resin material pivoted to one side of the cut portion of the main body member; The pipe is pivotally supported and engageable in a clamp groove formed in the axial direction on the other side of the cut portion of the main body member, and when the clamp operator is tilted away from the cut portion, the pipe The pipe leg is provided with a clamp fitting for tightening and holding the main body member around the leg, and the pipe leg is prevented from slipping. Then, by tilting the clamp actuator away from the cut part and tightening and fixing the clamp fitting against the pipe leg, you can easily install the anti-slip by hand and also tighten the clamp actuator itself. Embedded in the main body member to obtain stable tightening and fixing properties,
Moreover, it can be easily removed using a hand tool such as a screwdriver if necessary. Also,
Since it is a single component, it is easy to handle. Hereinafter, the present invention will be explained in more detail based on examples.

〔Example〕

FIG. 1 is a schematic perspective view showing the pipe leg anti-slip according to the present invention installed on the pipe leg before being tightened. In FIG. 1, the anti-slip 10 is a main body member 12 that is attached to a pipe leg provided on the lower surface of furniture such as a chair, table, or rack facing the floor for anti-slip purposes or to obtain a cushioning effect. The main body member 12 is formed as an annular body having 14 anti-slip irregularities on its outer surface, that is, the surface that is in direct contact with the floor surface, and has a cut shape cut in one place in the axial direction. having a portion 16;
This cut portion 16 allows it to be expanded so as to be attached to the outer periphery of the pipe leg P. Here, the main body member 12 is conveniently made of a soft elastic material, for example, synthetic resin such as vinyl chloride, urethane, polyethylene, etc. It is also possible to form the main body member 12 using synthetic rubber, or by a molding method using a mold. Processed and manufactured. Of course, it goes without saying that the anti-slip unevenness 14 can also be integrally molded. This main body member 1
A through hole (not shown) is previously provided on one side of the cut portion 16 of No. 2, and the pin 1 is inserted into this through hole.
A clamp actuator 20 is attached via 8. The clamp actuator 20 is made of a hard or semi-hard material, such as well-known nylon 6, ABS resin, etc.
Using a material such as polyamide resin, Diuracon, polyaceryl resin, or polycarbonate, it has a U-shape from the front as shown in FIGS. formed as a pivoting body with equal radius of curvature, 2
The two legs 22, 24 are separated by a space width equal to the axial length of the body member 12. Both legs 22, 24 have two holes 26, 2 passing through them.
8 is bored, and the aforementioned pin 18 is passed through the hole 26 and pivotally attached to the main body member 12. The clamp actuator 20 also has a base 30, on the inside of which is formed a stepped portion 32 that performs a locking action, which will be described later, and the tip 34 is countersunk in the width direction so as to sink into the main body member 12. ing. Now, referring again to FIG. 1, a clamp fitting 36 is provided in the hole 28 of the clamp actuator 20 pivotally connected to the main body member 12.
is pivoted. Like the clamp actuator 20, the clamp fitting 36 is curved to have the same curvature diameter as the main body member 12, and has a substantially U-shape. Then, the clamp fitting 36
Since the front edge wire 38 is a strong core wire for clamping that engages with the clamp groove 40 of the main body member 12, it is desirable that the clamp fitting 36 be formed of piano wire.

The pipe leg anti-slip 10 of the present invention having the above-mentioned structure is fastened to the pipe leg P by expanding the main body member 12 around the pipe leg P with its cut portion 16 as shown in FIG. After mounting, the clamp operator 20 is once tilted in the direction of the cut portion 16, and the front edge line 38 of the clamp fitting 36 is aligned with the main body member 1.
2 into the clamp groove 40, and then manually tilt the clamp actuator 20 in the direction away from the cut portion 16, the clamp fitting 36 is pulled along with it, and the main body members 12 are mutually connected at the cut portion 16. Since it acts to bring the clamp actuator 20 closer to
When the main body member 12 is completely lowered onto the circumferential surface of the main body member 12, the main body member 12 is attached while exerting a strong tightening force around the pipe leg P. In other words, a detent force is obtained. The dashed lines in FIG. 2 show the clamp actuator 20 and the clamp metal fitting 36 in a state where the tightening and installation is completed, and the clamp actuator 20 has its tip 34 sunk into the groove between the concaves and convexes 14 of the main body member 12. , the stepped portion 32 is configured to engage with a hook portion 42 formed inside one of the convex portions to maintain stable engagement. The clamp groove 40 formed in the main body member 12 is provided with another clamp groove at a position facing away from the cut portion 16 in order to strengthen the clamping force when the main body member 12 made of a soft material expands due to the influence of temperature. 40a may be formed in advance. Also, when removing the anti-slip 10 according to the present invention as necessary, the tip 3 of the clamp actuator 20
4 with a common screwdriver, the clamp actuator 20 pivots about the shaft 18 and separates from the body member 12. Therefore, the front edge line 38 of the clamp fitting 36 can be easily separated from the clamp groove 40, thereby allowing the anti-slip 10 to be removed from the pipe leg P.

[Effect of idea]

The present invention has been explained above based on examples, but
According to the present invention, the anti-slip with good tightening adhesion to the pipe leg can be attached with a simple so-called one-touch operation, and the anti-slip unevenness of the main body member made of a soft material prevents direct contact between the pipe leg and the floor surface. This provides an anti-slip effect and a cushioning effect, and also prevents the risk of the clamp actuator and clamp metal fittings sinking into the main body member, causing them to come off during use, or damaging the floor surface with the clamp metal fittings. It has the effect of not having any at all. Furthermore, the anti-slip device of the present invention has the advantage that no processing is required for attaching the anti-slip device to the pipe leg side. Furthermore, the ease of removal is advantageous in that the user of the floor fixture can easily replace the anti-slip as needed.
