Description

Safety helmet lens group (2)

The present creation is a safety helmet lens set (2), especially a flip cover with more stable positioning and less effort.

Press, the so-called safety helmet lens group refers to the collective name of the lens (windshield or sunshade lens) and the visor (or bracket) connected and assembled into a component. The lens group can not only be installed by a plurality of fasteners on the visor On half-hood or 3/4-hood helmets, the whole set can also be sold separately for consumers to directly install in front of the helmet shell to achieve the purpose of blocking wind, rain and sunshade.

Press again, the applicant has applied for a new patent No. M607252 "Headgear Lens Set". Although the previous patent can achieve a relatively stable and reliable effect of the flip cover, but after actual use, it is found that there are still some defects, which are worth repeating. further improvement.

Since the left and right ends of the visor and the lens are pivoted and positioned by means of a fixing member (such as a rivet), the upper and lower flaps of the lens are positioned, mainly relying on the friction between the visor and the lens; in detail, That is to say, when the riveting is tight, the positioning of the upper and lower lids can be relatively stable, but the operation is more laborious, and the friction generated is also large, which leads to easy wear and tear and cannot be used, thus reducing its service life. On the contrary, if the riveting is loose, the lens is prone to loosening and automatically move down.

In view of this, the applicant of this creation instructs the creator to uphold the belief of excellence, and then concentrate on research and improvement, and finally this creation will come into being.

The main purpose of this creation is to provide a safety helmet lens set (2) with a more stable and labor-saving flip-cover positioning, so as to improve the deficiencies of those who are familiar with it.

In order to achieve the above-mentioned purpose, the present creation system includes: a visor, which is arranged at the front end of the cap shell, the front end has a recess, and the left and right ends each extend downward with an extension portion, and the bottom end of the extension portion has an engaging hole; and a lens, which is arranged at the front end of the visor, the left and right sides are pivotally fixed with the visor by a fixing piece, and the inner side of the top end of the lens has a protruding piece, which can be abutted with the recess of the visor to serve as a lens cover When closing the lower limit, the left and right ends of the lens are each provided with an elastic piece, and the inner side of the elastic piece is protruded with a locking lever, which can be engaged with the engaging hole of the visor and positioned as the upper limit of the lens to be lifted up. The positioning of the flip cover is more stable.

In the above-mentioned safety helmet lens group (2), the upper ends of the left and right sides of the visor are each provided with a blocking piece.

In the above-mentioned safety helmet lens group (2), the lens is provided with an inverted U-shaped notch on the periphery of the elastic piece.

Herein, a preferred feasible embodiment is given in conjunction with the accompanying drawings, and the structural features and effects of the present creation are described in detail as follows, so as to facilitate the understanding and approval of those above.

First of all, please refer to Figures 1 to 3 at the same time, this creative department includes:

A visor 1, in the shape of an arc concave, has a plurality of fasteners 11 (female buckles) on the upper end to be fastened with a plurality of fasteners (male buttons) at the front end of the cap shell 3, so that the cap bill 1 is installed and positioned on the cap shell 3 The front end of the visor 1 has a recess 12 in the middle, and the ends of the left and right sides extend downward with an extension portion 13. The end surface of the extension portion 13 is in a flat plane state, and a circular The engaging hole 14, the upper ends of the left and right sides of the visor 1 are respectively provided with a blocking piece 15; and

A lens 2, in the shape of an arc concave, is pivotally fixed to the visor 1 (extension 13) at the left and right ends by a fixing member 21 (such as a rivet), so that the lens 2 is positioned at the front end of the visor 1, and is connected with the visor 1. The extension portion 13 of the tongue is in a flat surface contact state. There is a protruding piece 22 in the middle of the top of the lens 2, and a spring piece 23 at the left and right ends. The stop lever 24 can be a hemispherical arc body, and its diameter is smaller than the aperture of the visor engaging hole 14. The lens 2 is provided with an inverted U-shaped groove 25 on the periphery of the elastic piece 23, so that the The elastic pieces 23 have elastic force.

According to the above-mentioned structure combination, the left and right ends of the visor 1 and the lens 2 are pivotally fixed by a fixing member 21, and then the plurality of fasteners 11 on the visor 1 are buckled and positioned with the cap shell 3, so that the lens 2 is installed and positioned. At the front end of the cap shell 3 and in a closed state, as shown in FIG. 1 , at this time, the protruding piece 22 of the lens is abutted in the concave chamber 12 of the visor. If you want to lift the lens 2 up, you only need to press the lens 2 with a slight force to move it upward, and use the fixing member 21 as the rotation axis to make the locking rod 24 slide into the engaging hole 14 of the visor, then the The lens 2 is opened and positioned, as shown in Figures 4 and 5. Conversely, as long as the lens 2 is moved down again to make the locking rod 24 come out (disengage) from the locking hole 14, the cover state shown in FIG. 1 can be restored.

The above combinations and operations are worth mentioning:

1. The locking lever 24 of the lens is a hemispherical arc body, and is located inside the end of the elastic piece 23, and its outer diameter is smaller than that of the engaging hole 14, so once the lens 2 is moved upward, The locking lever 24 can be slid into the engaging hole 14 along the planes of the extension portions 13 on both sides of the visor 1 by the elastic force of the elastic sheet 23 to be engaged and positioned to serve as the upper limit of the lens 2 to lift up. Conversely, if the lens 2 is moved down, the locking lever 24 can be pulled out (disengaged) from the engaging hole 14 by the elastic force of the elastic piece 23, so that the protrusion 22 of the lens can abut in the concave cavity 12 of the visor to serve as a lens 2 Cover the lower limit. Therefore, in operation and use, not only the effect of more stable positioning of the flip cover can be achieved, but also more labor and ease.

As mentioned above, since the operation of positioning the upper and lower cover of the lens 2, since it relies on the elastic force of the shrapnel 23, the operation is relatively labor-saving and easy to operate, and naturally the friction between the visor 1 and the lens 2 can be reduced. Reduce the wear between the two, thereby extending its service life.

The upper ends of the left and right sides of the visor 1 of the present invention are each provided with a blocking piece 15. When the lens 2 is moved up and opened for positioning, the blocking piece 15 can also be used to block the lens 2 at the same time, so that the top of the lens 2 has a double The upper limit is shown in Figures 4 and 5.

Therefore, it can be seen from the above description that the present invention actually has the effect of more stable positioning of the flip cover and less labor-saving, and is far more advanced than the prior art.

To sum up, the specific structure disclosed in this creative embodiment has been found to be unknown to those who are familiar with it, and it can achieve the expected purpose and effect. Application.
