Description

Structural improvement of safety helmet shell

This creation is about the structural improvement of the helmet shell.

I have applied for the invention patent No. 111120949, "Structure of Hard Hat Shell", and the new patent No. 111209681, "Structure of Hard Hat Shell"; the patent scope of the above two cases is as follows:

A helmet decorative shell in the shape of an animal head, which can be installed on the upper edge of the helmet shell to decorate the helmet. The animal head shape is installed on the back side of the decorative shell, and its face is toward the rear of the decorative shell. , the animal head represented by this decorative shell has a structural shape above the upper half of the mouth;

There is one opening on the left and one on the right, respectively located on both sides of the lower edge of the animal head shape;

In this way, from the perspective of the left rear or right rear of the decorative shell, one side of the animal's head shape can be used to overlap the image of the opening on the same side, making people think that the opening is the mouth of the animal's head shape. This optical illusion achieves the effect of visual illusion.

More detailed examples of the above two cases:

1. Animal Example: (As shown in Figures 8 and 9)

A helmet decorative shell 2 with a "lion" animal head shape 1 can be installed on the upper edge of the shell of the helmet 3 to decorate the helmet 3. The front side of the decorative shell 2 can be extended by itself or externally connected. At least one ventilation cover 7 is added in the connection mode; the animal head shape 1 is provided on the rear side of the decorative shell 2, and its direction is toward the rear of the decorative shell 2 (when the decorative shell 2 is combined with the safety helmet 3, the animal head shape 1 It is also facing toward Shown from the rear of the helmet 3), the animal head presented by the decorative shell 2 is the shape of the upper half of the mouth (including: the upper lip of the lion's mouth, face, nose, eyes, forehead and mane... ..and other structures);

There is an upper fang 4 on each left and right, respectively located on both sides of the lower edge 9 of the animal head shape 1 (that is, both sides of the lower edge of the rear side of the decorative shell 2); (the so-called lower edge 9 here refers to the animal head The entire lower edge of the facial shape 1, including the lower edge of the nose in the middle)

There is a chin 5 on the left and right respectively, respectively located below the two sides of the lower edge 9 of the animal head shape 1 (that is, below the two sides of the rear side edge of the decorative shell 2). The two outer sides of the left and right chins 5 The ends are respectively connected with the left and right sides of the rear side of the decorative shell 2 to form;

To explain from another angle, the left and right chins 5 can be respectively formed by extending from the left and right sides of the rear side of the decorative shell 2 toward the center of the rear side of the decorative shell 2;

The left and right fangs 6 are respectively located at the two inner ends of the left and right chins 5, that is, the two extended ends of the left and right chins 5.

Description of the structural principles of the above-mentioned prior art:

As shown in Figure 8, if viewed from the perspective of directly behind the decorative shell 2 (or safety helmet 3), the left and right openings 8 are respectively located on both sides of the animal head shape 1, making people feel that the animal head shape 1 is The left and right openings 8 have nothing to do with each other;

As shown in Figure 9, if the viewing angle is moved to the left or right rear side of the decorative shell 2 (or safety helmet 3), one side of the animal head shape 1 will intersect with the image of the opening 8 on the same side. The image of the opening 8 on the same side will be displaced below the animal head shape 1 due to the viewing angle, which will make people mistakenly believe that the opening 8 on the same side is the mouth of the animal head shape 1 The "optical illusion" achieves the effect of "visual illusion"; therefore, the shaped animal face can be created by using the shape change of the opening 8 Various expressions of joy, anger, sadness or joy.

2. Eagle bird embodiment: (shown in Figures 10 and 11)

A helmet decorative shell 12 with an "eagle" animal head shape 11 can be installed on the upper edge of the shell of the helmet 3 to decorate the helmet 3. The front side of the decorative shell 12 can be extended by itself or At least one ventilation cover 17 is added in the external connection mode; the animal head shape 11 is provided on the rear side of the decorative shell 12, and its direction is toward the rear of the decorative shell 12 (when the decorative shell 12 is combined with the safety helmet 3, the animal head shape 11 is also facing the rear of the helmet 3), and the animal head represented by the decorative shell 12 is a structural shape above the eagle's upper beak 14 (including: the eagle's upper beak 14, the eagle's face, the eagle's eyes and the forehead) ...and other structures;

The left and right lower beaks 15 are respectively located below the two sides of the lower edge 19 of the animal head shape 11 (that is, below the two sides of the rear side edge of the decorative shell 12). The two left and right lower beaks 15 The outer end is connected to the left and right sides of the rear side of the decorative shell 12 respectively; (the so-called lower edge 19 here refers to the entire lower edge facing the eagle head shape 11, including the middle eagle hook upper beak 14 fate)

To explain from another angle, the left and right lower beaks 15 can be respectively formed by extending from the left and right sides of the rear side of the decorative shell 12 toward the center of the rear side of the decorative shell 12;

The left and right hooked beaks 16 are respectively located at the two inner ends of the left and right lower beaks 15, that is, the two extended ends of the left and right lower beaks 15.

Description of the structural principles of the above-mentioned prior art:

As shown in FIG. 10 , if viewed from the perspective of directly behind the decorative shell 12 (or safety helmet 3 ), the left and right openings 18 are respectively located on both sides of the animal head shape 11 , making people feel that the animal head shape 11 is in contact with the animal head shape 11 . The left and right openings 18 have nothing to do with each other;

As shown in Figure 11, if the viewing angle is moved to the left or right rear side of the decorative shell 12 (or the helmet 3), one side of the animal head shape 11 will intersect with the image of the opening 18 on the same side. Stacked, and the same side should be opened The image of the mouth 18 will appear to be displaced below the animal's head shape 11 due to the viewing angle, which will cause people to mistakenly believe that the opening 18 on the same side is the mouth of the animal's head shape 11. The effect of "visual illusion" is achieved; therefore, the shape change of the opening 18 can be used to create various expressions of happiness, anger, sadness or joy on the face of the shaped animal.

Problems with the above-mentioned prior art:

1. As shown in Figures 8 and 9, the setting of animal fangs (upper fangs 4, lower fangs 6) can easily show the animal’s powerful expression and appearance, so for tigers, leopards, lions, wolves , bear, shark, snake,. ． ． ． "Fangs" are an indispensable component in the expression design of ferocious animals such as animals.

2. However, the sharp ends of the fangs are dangerous, especially if they are installed on safety helmets. It is easy to accidentally stab people in the back seat of the motorcycle and bystanders.

3. The independently protruding outer structure of the upper fangs 4, lower fangs 6 and chin 5 is also easily broken due to collision, causing damage.

4. As shown in Figures 10 and 11, the sharp ends of the upper hook beak 14 and the sharp ends of the left and right lower hook beaks 16 are also dangerous problems.

5. The independently protruding outer structure of the lower beak 15 and the lower hooked beak 16 is also easily broken due to collision, causing damage.

The purpose of this creation is to provide a better creative design for the structure of the helmet shell, mainly to solve the above-mentioned problems of the prior art.
