Description

[Detailed Description of the Invention] This invention relates to a fixing device for a synthetic resin faucet bundle.

Synthetic resin bundles come in a wide variety of colors and are aesthetically pleasing, and even when attached to a hot water faucet, they do not have the problem of being too hot to touch like metal bundles, so metal bundles are preferred. It is preferred to be used instead of.

However, if synthetic resin bundles are made of hard synthetic resin, they cannot exhibit high transparency or bright colors, so they must be hard or have low mechanical strength. If the serration hole of the bundle is attached to the retaining part of the serration part of the spindle, the serration hole may become sagging or deformed due to long-term use of the bundle, resulting in wear and tear, which may cause the bundle to wobble. there were.

From this point of view, as shown in FIG.
The bushing 53 is engaged with the upper end of the bushing 53.
A bundle 51 made of synthetic resin is engaged with and secured to the spindle 55 via a bush 53 using a screw 57 or the like.
A bundle fixing device is known which has a structure in which gently inclined polygonal pyramidal surfaces 52 and 54 that engage with each other are formed on the outer surface of the bundle 51 and the inner surface of the bundle 51, respectively.
(See Publication No. 52).

However, in this case, the concave portion 56 of the bundle 51 is fitted into the bush 53, and the gently inclined polygonal pyramidal surface of the bundle 51 is
2 is engaged with the gently inclined polygonal pyramidal surface 54 of the bushing 53, and the bushing 53 rotates in conjunction with the rotation of the bundle 51, so that the bundle 5 also made of synthetic resin
It was inevitable that the bushing 53 would become loose after long-term use.

This idea was made in view of the above-mentioned circumstances, and
It is an object of the present invention to provide a bundle fixing device that can firmly fix a synthetic resin bundle to a spindle and that does not cause the bundle to wobble even after long-term use.

The bundle fixing device of this invention includes a bundle fixing member made of a hard material having a serration hole that engages with the serrations of a faucet spindle and an outer circumferential surface having a polygonal horizontal cross section, and a bundle fixing member made of a hard material having an outer peripheral surface having a polygonal horizontal cross section into which the fixing member is forcibly fitted. The bundle fixing member has a plurality of spindle clamps separated by a plurality of slits that have a diameter larger than the inner surface of the recess at the lower part and extend from the lower end to near the upper end. Attached means that it has a part.

Examples of this invention will be described below.

In FIGS. 1 to 4, reference numeral 1 denotes a cap-shaped faucet handle body, which is made of synthetic resin with excellent transparency.

Reference numeral 2 denotes a fitting recess formed on the lower surface of the center of the handle body 1, which has a hexagonal horizontal cross section.

3 is a screw fixing recess formed on the upper surface of the center of the handle body 1; 4 is a small hole drilled in the axial center of the handle body 1 and communicating with the upper and lower recesses 2 and 3; 5 is a fitting recess. This is a handle fixing member that is forcibly fitted into position 2 and is made of hard synthetic resin such as polyacetal resin.

The outer circumferential surface 7 of the fixing member 5 has a hexagonal horizontal section with a size corresponding to the fitting recess 2, and a hexagonal pyramidal surface that tapers slightly upward.

Further, a serration hole 9 is formed in the axial center of the fixing member 5.

A top wall 11 having a through hole 10 in the center is provided at the upper end of the handle fixing member 5, and a flange portion 12 is provided at the lower end.

Reference numeral 13 denotes a plurality of radial horizontal cross-sectional slits formed at regular intervals in the handle fixing member 5, and these slits are cut from the lower end and extend to near the upper end.

As shown in FIG. 3, these slits 13 form a plurality of spindle fastening portions 17 in the handle fixing member 5, each of which has a fan-shaped cross section and which are connected to each other at their upper ends.

6 is a faucet spindle, which has serrations 8 at the upper end.
has.

A female screw portion 14 is formed in the serration portion 8 in the axial direction.

The serration portion 8 is inserted into the serration hole 9 of the handle fixing member 5 in a fixed manner.

Further, a fixing screw 15 is passed through the small hole 4 of the handle body 1 from above, passes through the through hole 10 of the handle fixing member 5, and is screwed into the female threaded portion 14 of the serration portion 8.

In this way, the handle body 1 is fixed to the faucet spindle 6.

16 is a screw cap fitted into the recess 3 from above.

The faucet handle fixing device according to this invention is constructed as described above, and the handle fixing member 5 has the serration holes 9.
and an outer circumferential surface 7 having a polygonal horizontal cross-section, and the handle body 1 has a downwardly opening recess 2 having a polygonal horizontal cross-section. By engaging the serrations 8 and tightly fitting the fixing member 5 into the recess 2 of the handle body 1, the handle body 1 is securely fixed to the faucet spindle 6 via the handle fixing member 5. I can do it.

Furthermore, since the handle fixing member 5 is made of a hard material, the serration hole 9 may become sagging or deformed at the engagement portion between the serration hole 9 and the serration portion 8 of the faucet spindle 6 due to long-term use of the handle. Therefore, there is no risk of the handle becoming loose due to wear of the serration holes.

Furthermore, the handle fixing member 5 has a larger diameter than the inner surface of the recess 2 at the lower part, and has a plurality of spindle fastening portions 17 separated by a plurality of slits 13 extending from the lower end to near the upper end. 5 is attached to the faucet spindle 6, and when the recess 2 of the handle body 1 is forcibly fitted into the fixing member 5, the tightening portion 17 is pressed inward by the inner circumferential surface of the recess 2. As a result, the faucet spindle 6 is tightened, and the serration portion 8 and the serration hole 9 of the rotation prevention member 5 are tightly engaged with each other.

Therefore, it is possible to firmly fix the synthetic resin type handle to the faucet spindle 6, so that the handle can be firmly fixed to the faucet spindle 6.
In addition to being able to completely eliminate the problem of idle rotation, this faucet handle has no risk of wobbling even after long-term use.
