Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a retroreflector that is attached to the spokes of a wheel such as a bicycle.

Although many models of this type of reflector have existed in the past, most of them require accessories such as bolts and nuts to attach the reflector to the spokes. There is also a one-touch structure that is molded from synthetic resin and has spokes sandwiched between the wings, but this also does not allow the spokes to be clamped at a constant distance due to production conditions, making it impossible to mount them as planned. In other words, a specific example is Fig. 1A,
As shown in B, the reflective surface (ω and the middle of the wing section) is integrally molded with synthetic resin material, and elastic tongues (C) are formed on each of the wing sections + b + peaks. Layer the two element bodies so that they face each other, and one wing part (b) (b)
There are protrusions (small < d+) that are fixed by ultrasonic welding. However, the solution of the protrusions varies depending on the adjustment of the working conditions in ultrasonic work, so each product is different after welding. The spacing between the spokes is different, which causes some drawbacks such as looseness when attached to the spokes, or the fact that the spokes are too stiff and difficult to install.

According to the present invention, in a retroreflector, the means for attaching the spokes to the spokes provided symmetrically on both sides of the reflective part is provided between the spokes of a wheel with spokes, and the spokes can be fitted from the outside. and a portion for positioning the spokes, a first holding mechanism for holding the spokes in pressure contact with each other in the axial direction of the wheel, and a second holding mechanism for positioning the spokes in the inter-spoke direction of the wheel are disposed at the portions, and Provided is a retroreflector characterized in that the means is integrally formed.

The retroreflector of the present invention has the following advantages: (Since the means for attaching it to the D spoke is integrally molded, desired and accurate dimensions can be maintained, and there are fewer manufacturing parts, which increases production cost efficiency; (ii) Since the attachment means includes a suspension mechanism for positioning and holding the spokes at predetermined positions, it has advantages such as being able to stably fix the spokes without wobbling during running.

In the mounting means of the present invention, the "first holding mechanism that presses the spokes in the axial direction of the wheel" is a mechanism that has the function of preventing deflection of the retroreflector in the longitudinal direction of the spokes and in the axial direction of the wheel. It is made up of at least two members having dimensions that allow the spokes to be pressed against each other (that is, an interval that is approximately the same as the diameter of the spokes) and a certain width in the longitudinal direction of the spokes.

In addition, the "second holding mechanism for positioning the spokes in the direction between the spokes" is mainly used to prevent wobbling in the direction between the spokes during use, and the retroreflector is installed at a desired position between the spokes. means a mechanism that is held in position when the

Specifically, it includes a so-called point support mechanism that contacts the spokes in a point-like manner with respect to the length direction of the spokes at four points at intervals that are approximately the same as the diameter of the spokes.

The present invention will be described in detail below with reference to the drawings, but the present invention is not limited to the following examples.

Embodiments will be explained based on FIGS. 2A, B, and C and 3A and B. (1) [1') is a reflective part (1') made of synthetic resin and consisting of a group of triangular pyramidal reflective elements on the inner surface. 21 (2')
The reflection element body (1) has mounting means (3) [3') integrally molded at symmetrical positions on both sides of one reflection element body (1).

This attachment is carried out by attaching the means (3) (3') to the central fitting part of the reflective element body (1) on the other reflective element body (1').

The mounting means (3) includes a first mounting piece (4) that is flush with the -□ surface of the reflective element body (1) and protrudes from the center of the side of the reflective element body (1); ) Other aspects and

The spokes (8) are held in pressure contact with each other in the axial direction of the wheel by the inner surfaces (61 (7117)) of the first mounting piece (4) and the second mounting piece (5) (5). The first mounting piece (4) and the second mounting piece (51) located at

Projections 001001 are provided on the outer edges of the inner surface (7)q of the second mounting piece +51 (5'), and roughly the inner surface (7) of the second mounting piece (5) is provided with a protrusion 00). A base part opening 1) (a part of the side wall formed on both sides of the reflective part) is provided at a slight interval Y, and a protrusion (10) and a base part (11) are provided.

The recess between the base part (1υ) ('121 interval Y interval is almost the same as the spoke diameter, and the spokes (8) are positioned and held in the inter-spoke direction by being located within this recess (+21). By holding the spoke in two directions by a first holding mechanism and a second holding mechanism, the reflector is firmly attached to the spoke.

In the above embodiment, the second holding mechanism has 0 protrusions.

However, in actual use, the spoke conditions of the wheels are not the same for each bicycle, so in that respect, the point support shown in the above example is not suitable. It is convenient in that the direction of the mechanism can be adjusted appropriately. [E in Figure 2 A is the spoke in a different state of another bicycle, and if it is point supported, it will be held without any problem. Of course, the holding mechanism may also be provided on the second mounting piece (5), and its arrangement is as shown in FIG.
