Description

helmet

The invention relates to a helmet, in particular to a rational design of the structure, and the cover and the sun visor fixing mechanism are separately arranged, and can be easily and quickly disassembled and installed.

According to the custom helmet, the way to set the shield (or lens) and the sun visor (or the visor) is currently divided into two types:

(1) The shield and the sun visor share a fixed mechanism or are fixed by a common shaft. This method has the following defects:

1. The mechanism is complicated. Because it must take care of the fixing and operation of the shield and the sun visor at the same time, the mechanism is inevitably complicated.

2. The mechanism is complicated, the hole in the helmet body should be large or deep, so that it can be accommodated, so it may reduce the strength of the structure of the helmet; or it may be partially assembled on the outer side of the helmet, but it may affect the overall helmet due to excessive protrusion. Beautiful.

3. Whether it is a shield or a sun visor, it is easy to use due to long-term operation, causing mutual influence and then causing looseness or damage.

4. Whether it is a shield or a sun visor, it cannot be quickly disassembled or fast loaded.

(2) The sun visor does not share a fixing mechanism or a common shaft with the shield, but is separately fixed by a screw to the top of the shield, but the sun visor cannot be quickly disassembled and fast loaded.

Nowadays, due to the trend of the times, most of the current locomotive riders have a variety of different shapes, functions, color shields and sun visors, which are used in response to different needs. Therefore, users need to change the shields or sun visors more frequently.

The guide groove 32 can be used to gradually move up until the top end of the guide groove 32 is stopped by the stopper 371, as shown in Figs. On the other hand, if the cover piece 39 is to be closed, the cover 30 is pulled down, and the cover 30 and the hollow shaft 36 are used as the rotation axis, and the tooth row 37 can be moved downward according to the guide groove 32, so that the cover can be moved downward. 30 can be positioned by a positioning mechanism (such as a cassette) to restore the closed state shown in Figures 1, 2, 4, and 5.

If the shroud 30 is to be removed, the pressing button 342 can be pressed down (the two hands can be pressed at the same time, and the pressing can be performed once and twice), so that the convex 341 of the elastic pressing button element and the hollow rotating shaft 36 of the shroud are provided. The detachment 30 can be removed by disengaging (uncoupling the axial positioning), as shown in FIG. On the other hand, if the cover 30 is to be installed, the hollow shaft 36 at both ends of the cover is placed in the base slot 33, so that the slot 38 is engaged with the base 31, and then the force is pushed backwards. The elastic knob element 34 is pressed down by the hollow rotating shaft 36, and the arc-shaped convex rib 341 is locked into the hollow rotating shaft 36 for positioning, so that the shield 30 can be assembled and positioned, and restored as shown in FIGS. 1, 2, 4, and 5. The cover is in use, when the elastic latch 35 is engaged with the tooth row 37, and one end of the tooth row 37 is located on the guide groove 32.

If the sun visor 40 is to be removed, as long as the push button 451 is pushed up (can be pushed up by both hands at the same time, it can be divided twice at a time), and the push button member 45 is rotated by an angle to make the hook 452 and the sun visor The hook 47 of the cassette is disengaged (unplugged and positioned), and the damper 48 is removed from the slot 13 to remove the visor 40, as shown in FIG. On the other hand, if it is to be installed, as long as the sun visor 40 is held, the latching tabs 46 at the opposite ends thereof are inserted into the housing sliding groove 42, so that the two hooks 47, 452 are engaged with each other, and the middle of the rear side is inserted. The sheet 48 is inserted into the notch 13, and the sun visor 40 can be assembled and positioned to restore the state shown in Figures 1, 2 and 7.

Also, it is worth further highlighting that the description includes:

1. The notch 13 can be directly disposed on the helmet body 1, or disposed on the top fitting 14 as described above, and the top fitting 14 can be combined with the helmet body 1 to be connected to the sun visor insert 48. The same purpose.

2. The base 31 of the shield fixing mechanism and its related components, or the housing 41 of the sun visor fixing mechanism and its related components, may be directly disposed at the left and right ends of the helmet body 1, or disposed on the frame unit 2 as described above. Both ends of the left and right sides can achieve the same purpose of disassembling, installing the cover 30 or the sun visor 40.

3. The frame unit 2 can be integrally formed with the base 31 of the shield fixing mechanism, or as described above, and can be integrally formed with the base 31 of the shield fixing mechanism and the housing 41 of the sun visor fixing mechanism. The same purpose of installing the shield 30 or the sun visor 40.

4. The shield fixing mechanism 3 is mainly configured by a hollow shaft 36 of the shield and a protruding block 341 of the base elastic button member. Therefore, it can be said to be a shaft fixing mechanism. On the contrary, when the button member 34 (press button 342) is pressed to disengage the protruding member 341 from the hollow shaft 36, it can also be regarded as a mechanism design for uncoupling the positioning of the shield 30.

5. After the shield 30 is fixed, the tooth row 37 that is engaged with the elastic latching teeth 35 can be used to segment the upper and lower flaps according to the curved guide groove 32.

6. The sun visor fixing mechanism 4 mainly engages the latching piece 46 and the insertion piece 48, and is inserted into the sliding slot 42 and the notch 13 respectively for insertion and positioning, so that it can be said to be a plug fixing mechanism. On the other hand, when the push button member 45 (the push button 451) is disengaged from the two hooks 452, 47, it can also be regarded as a mechanism for undoing the insertion position of the sun visor 50.

7. The present invention can utilize a helmet body 1, a chin guard 10, and a frame unit 2 with a separate shield fixing mechanism 3 to form a complete helmet; or, by a helmet body 1, a chin guard 10, and a frame unit 2 Together with the separate sun visor fixing mechanism 4, a complete helmet is formed; the same function of quick release and quick loading of the shield 30 or the sun visor 40 can be achieved respectively.

8. The present invention is provided with an inner lens 5 on the inner side of the helmet body 1. As shown in FIG. 2, the inner lens 5 is generally used for shading, and can be used by segmenting the upper and lower lids.

Therefore, from the above description, the present invention has at least the following advantages and functions, and is far more advanced than the prior art.

1. The housing 12 of the helmet body 1 at the periphery of the opening 11 is a slightly concave shallow groove, which does not substantially affect or detract from the structural strength of the helmet body, and is a rational structural design.

2. The base 31 and the housing 41 are integrally formed with the frame unit 2, and the rationalized structural design is also implemented, which also makes the structure of the present invention simpler.

3. The disassembly and assembly of the shield 30 is very simple, easy and fast, and can achieve the effects of quick release and quick loading.

4. The disassembly and assembly of the sun visor 40 is also very simple and easy, and can achieve the functions of quick release and quick loading.

5. The quick release of the shield 30 or the sun visor 40 not only does not require tools and screws, but also can be operated by a single button (press button 342, push button 451), which is quite convenient in use.

However, the embodiments described above are intended to illustrate the feasibility of the present invention, and the equivalent structural changes of various parts such as a separate shield fixing mechanism, a sun visor fixing mechanism, and a frame unit using the design of the present invention, And the quick-release of the shield and the sun visor, the design spirit of the quick-loading, and the like, are still considered to be included in the patent of the present invention.

In summary, the specific structure disclosed in the present invention is found to be unsatisfied by the prior art, and can achieve the intended purpose and effect, and can be called a novel and progressive invention, and has a profound industrial value. , 提出 filed an invention patent application in accordance with the law.
