Description

[Detailed Description of the Invention] <Industrial field of application> This invention prevents scratches on the desk or floor when various appliances such as TV, radio, video, toaster, stove, and furniture are placed. At the same time, the present invention relates to a protective leg that is attached to the mounting hole on the lower surface of the device by protruding downward so as not to slip.

<Prior Art> According to the applicant's Japanese Utility Model Publication No. 54-21252, a plastic leg body whose upper surface abuts a lower surface having a mounting hole for a device,
A cylindrical wall is provided integrally with the leg, the upper wall protruding upward from the upper surface and protruding into the mounting hole on the lower surface of the device, and a plurality of slits are formed in the upper portion of the cylindrical wall by slits cut from the upper end. The shaft of a pin consisting of a floor-contact piece that contacts the lower surface of the body and an integral shaft that stands up from the floor-contact piece is pushed into the cylindrical wall of the leg from below, and the leg is cut by the cut piece. Protective legs for appliances that are mounted in the mounting holes of the appliances are known. In order to prevent the equipment from slipping, the floor contact piece of the pin and the shaft are integrally molded with synthetic rubber, or the floor contact piece is molded with a material with a large friction resistance such as synthetic rubber, and the shaft and leg are It also proposes molding with similar plastics.

<Problems to be solved by the invention> As for the mounting strength of the leg to the lower surface of the device, it is preferable that the pin shaft is made of rigid plastic, but if the shaft and the floor-contacting piece are also made of plastic, the device will be on the desk. , Becomes slippery on the floor. Therefore, the floor-contacting piece is preferably made of a material having a large friction coefficient such as synthetic rubber.

However, it is impossible to integrally form the shaft with plastic and the floor contact piece with rubber. For this reason, it is conceivable to integrally form a disk-shaped brim on the lower end of the plastic shaft, and to fix the rubber contact floor piece to the lower surface of this brim by gluing,
If a force is applied to move the device laterally on the desk or floor, the rubber floor-bonding piece may peel off.

<Means for Solving Problems> Therefore, according to the present invention, a plastic leg body whose upper surface abuts a lower surface having a mounting hole of an appliance is projected upward from the upper surface, and an upper end portion is a mounting hole of the lower surface of the appliance. A protruding cylinder wall is integrally provided, and a plurality of slit pieces are formed in the upper part of the cylinder wall by slits cut from the upper end, and a floor-contact piece that abuts the lower surface of the leg and a stand-up piece from the floor-contact piece. In the protective leg of the device, in which the shaft of the pin consisting of an integral shaft is pushed into the tubular wall of the leg from below and the leg is attached to the attachment hole of the device by the slit piece, the pin is a shaft. It is equipped with a soft material layer that covers the entire surface of the floor-contacting piece formed by the two-color injection molding method after integrally molding the material and the floor-contacting piece with plastic, and the lower surface of the leg is covered with the soft material layer. It is characterized in that the surrounding wall surrounding the upper part of the floor contacting piece is projected downward. That.

<Embodiment> In the illustrated embodiment, reference numeral 1 denotes a flowerpot-shaped plastic leg body whose upper surface abuts a lower surface 4 having a mounting hole 3 of a device 2, and the leg body projects upward from the upper surface and has an upper end. A cylindrical wall 5 is integrally provided, the portion of which projects into the mounting hole 3 on the lower surface of the device, and a plurality of slit pieces 7 are formed in the upper portion of the cylindrical wall 5 by slits 6 cut from the upper end. Reference numeral 8 denotes a plastic pin composed of a floor-contacting piece 9 that comes into contact with the lower surface 1'of the leg 1 and an integral shaft 10 that stands upright from the floor-contacting piece.

In the embodiment of FIGS. 1 and 2, the cylindrical wall 5 on which the slit piece 7 is formed
The inner circumference of the upper part of the is a taper part 5a which is reduced in diameter upward, and the upper end of the cylinder wall is inserted into the mounting hole 3 on the lower surface of the instrument. When is pushed in, the upper end of the shaft 10 located in the upper end of the cylinder wall opens each slit 7 outwardly in a petal shape by the tapered portion 5a on the mounting hole 3, and the leg 1 is attached to the device. Attach to the hole.

Further, in the embodiment of FIGS. 3 and 4, the inner circumference of the tubular wall 5 of the leg has the same inner diameter from the top to the bottom, but the outer circumference of the upper portion of the tubular wall 5 on which the slit piece 7 is formed is temporarily turned upward. There is a double taper part in the opposite direction that expands and then reduces the diameter, and cut each piece 7 so that the maximum diameter part 5b at the boundary of the upper and lower taper parts appears just above the mounting hole 3 on the lower surface of the instrument. When the shaft 10 of the pin 8 is pushed from below into the mounting hole 3 by inserting the upper end of the cylindrical wall 5 into the mounting hole 3 from below and pushing the shaft 10 of the pin 8 downward, each slit 7 faces inward. It becomes undeformable and the leg 1 is attached to the attachment hole of the instrument.

Now, the floor-contacting piece 9 of the pin 8 formed integrally with the shaft 10 from plastic is provided with a soft material layer 11 of, for example, synthetic rubber having a large friction coefficient for covering the upper surface, the lower surface and the periphery thereof.

The soft material layer 11 can be easily formed by molding the shaft 10 of the pin 8 and the floor-contacting piece 9 with plastic and then coating the floor-contacting piece 9 with synthetic rubber or the like by a two-color injection molding method.

An enclosing wall 12 is provided on the lower surface of the leg 1 so as to surround an upper part around the floor-contacting piece covered with the soft material layer 11.

Further, it is preferable that the cylindrical wall 5 and the peripheral wall of the leg are connected by a radial reinforcing wall 13.

<Effect of the device> According to the present invention, the shaft 10 and the floor-contacting piece 9 are made of an integral plastic, so that the attachment strength of the leg to the device is high. Moreover, since the floor-contacting piece is covered with the soft material layer having a large friction coefficient, it is possible to reliably prevent the appliance from slipping on the desk or on the floor.

Moreover, since the soft material layer covers the entire surface of the floor-contacting piece by the two-color injection molding method and is completely integrated, the soft-material layer is peeled from the floor-contacting piece even if the device is laterally displaced on the desk or the floor. In addition, the soft material layer elastically supports the device with the upper and lower layers of the flooring piece and the lower surface of the flooring piece. Prevent slack between the bodies.

Further, the downward facing enclosure of the lower surface of the leg effectively prevents the upper layer on the upper surface of the flooring piece of soft material layer from collapsing and expanding, while at the same time effectively preventing the pin axis from wobbling and loosening.
