Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a safe protective sports helmet, and more particularly to a safe protective sports helmet which is structurally simple and convenient for adjusting, by rotating an adjusting button, a head size adjusting means can be adjusted to a size fitting a head size of a user easily; the sports helmet is applicable to ball games, car competitions and other sports in need of protecting the safety of the head of a user.

2. Description of the Prior Art

In sports having vigorous actions or limb contacts such as skating, skating with in-line skates, bicycle riding or playing a baseball game or a hockey ball game etc., once there is impact, such sports are subjected to inducing body injures, and among them head injures are most serious.

Thereby, in sports having vigorous actions or limb contacts, in order to avoid head injures, generally people put on safe protective sports helmets to diminish collision force during impacts. And designing of a safe protective sports helmet concentrates to light weight, vibration resisting and vibration absorbing, in order that a user can have convenience in use and for motion, still the head of the user can be appropriately protected.

Safe protective sports helmets now available in the market have fixed sizes and with tying belts to achieve the adjustment purpose. Thereby the user must choose and buy a safe protective sports helmet with a fixed size, and after adjusting the tying belt, he can wear the helmet firm. However, because of the tight tying belt, the user will feel discomfort when he wears the helmet for a long time and the tying belt renders the user look bad.

In view of the above defect of the conventional structure, the inventor of the present invention provides improvement after nonstop studying and developing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1-4 showing an embodiment of a safe protective sports helmet of the present invention, the sports helmet includes a hat body 1 which is provided therein with a circle of head encircling means 2 and is provided thereon rotatably with a rotatable adjusting button 3; the hat body 1 and the head encircling means 2 are movably connected by means of the rotatable adjusting button 3.

The hat body 1 has a hole 11. The head encircling means 2 is a belt member 20 having respectively on its two ends two openings 21, 22, and the two openings 21, 22 have on one side of each a line of engaging teeth 211 and 221 respectively. The rotatable adjusting button 3 has a central axle 31 for extending into a disk 32, the disk 32 has a gear 321 protruding centrally out of it; when in assembling, the gear 321 can exactly engage with the engaging teeth 211 and engaging teeth 221 of the two openings 21, 22 mutually aligned for connecting the two ends of the belt member 20. The central axle 31 of the rotatable adjusting button 3 then is extended through the two openings 21, 22 to make movable connection of the rotatable adjusting button 3 with the belt member 20. Hence when the rotatable adjusting button 3 is rotated left or right, the gear 321 of the disk 32 makes contracting and releasing of the belt member 20 and the two openings 21, 22 on the two ends of the belt member 20 are not separated for being restrained by the central axle 31.

The disk 32 is provided at the two sides of the gear 321 each with a hook 322; the root ends of the hooks 322 are connected with the disk 32, while the front ends of them each form with the disk 32 a gap 323. The hooks 322 each has a protrusion 324 on its outer side; the rotatable adjusting button 3 is provided inside thereof with protruding posts 33 for engaging the hooks 322 of the disk 32, Thus, when the rotatable adjusting button 3 is rotated, the disk 32 can be rotated by virtue that the hooks 322 are moved by the protruding posts 33. The hole 11 of the hat body 1 is provided therein with a plurality of clockwise or counterclockwise spines 111. Thereby, when the rotatable adjusting button 3 is not rotated, the protrusions 324 of the hooks 322 can exactly abut against the spines 111, hence the belt member 20 is maintained in a fixed state; when the rotatable adjusting button 3 is rotated clockwise or counterclockwise, the root ends of the hooks 322 in connecting with the disk 32 make the gaps 323 reduced by moving of the protruding posts 33, and make the protrusions 324 of the hooks 322 forced to snap forwards, thus the disk 32 is rotated; when the rotatable adjusting button 3 is rotated to the opposite direction (one of the clockwise and the counterclockwise directions), the front ends of the hooks 322 are moved by the protruding posts 33 to reduce the gaps 323, thus the protrusions 324 of the hooks 322 are released from the restraining of the clockwise or counterclockwise spines 111 to allow the disk 32 to rotate.

And the hat body 1 is provided therein with a plurality of protective cushions 12, the head encircling means 2 is provided between the hat body 1 and the protective cushions 12. Parts of the protective cushions 12 are fixed in the hat body 1, and other parts of the protective cushions 12 are connected with the head encircling means 2. Thereby when the rotatable adjusting button 3 is rotated left or right, the gear 321 makes contracting and releasing of the belt member 20, the head encircling means 2 can link up with the protective cushions 12 connected with it in order to adjust the head encircling means 2 to get a size fitting a head size of a user.

When in use, as shown in FIGS. 5-8, after the user wears the safe protective sports helmet of the present invention, he can make adjustment by rotating the rotatable adjusting button 3. When the rotatable adjusting button 3 is rotated to a direction, the gear 321 engaging with the engaging teeth 211 and 221 respectively of the two openings 21, 22 on the two ends of the belt member 20 is moved by the protruding posts 33 of the rotatable adjusting button 3 to link up with the two ends of the belt member 20 to form a contracting or releasing state. For example, when the rotatable adjusting button 3 is rotated clockwise, the engaging teeth 211 and 221 of the two openings 21, 22 respectively on the two ends of the belt member 20 are linked up to render the two ends of the belt member 20 to move in mutually opposite directions to get a contracting state; on the contrary, when the rotatable adjusting button 3 is rotated counterclockwise, the engaging teeth 211 and 221 of the two openings 21, 22 respectively on the two ends of the belt member 20 are linked up to render the two ends of the belt member 20 to move in mutually opposite directions to get a releasing state.

Thereby, the safe protective sports helmet of the present invention has a design in combination of the rotatable adjusting button 3 and the belt member 20 which makes the belt member 20 contract or release when the rotatable adjusting button 3 is rotated. The design is simple, costs low and yet is convenient for a user. No matter what head size is, the hat body 1 can be tightly and firmly fitting the user, thus the safety purpose can be also achieved.

The above stated is only for illustrating the present invention, and not for giving any limitation to the scope of the present invention. It will be apparent to those skilled in this art that various equivalent modifications or changes according to the idea of and without departing from the spirit of this invention shall also fall within the scope of the appended claims.

In conclusion, according to the description disclosed above, the present invention surely can get the expected object thereof to provide a safe protective sports helmet. Having thus described the technical process of my invention having high practical value, what
