Description:
BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates to a helmet comprising an earcap, a chin-strap and a wearing belt which are removably attached to said helmet along the inside surface thereof.
In conventional helmet structures, the ear-cap is usually riveted to the main body of the helmet and so the user cannot help but feel uncomfortable. If the ear-cap is fixed too tightly, the user becomes readily fatigued which can place him in some danger. Furthermore, although the ear-cap is in direct contact with the users' skin, it cannot be cleaned or changed because it is fixed to the helmet body. Thus, the conventional ear-caps have been used under dangerous and unsanitary conditions.
The conventional chin-strap used for the helmet is also riveted to the helmet body, thereby making it almost impossible to replace it when it becomes dirty or worn. Some chin-straps are removably attached to the helmet, however, because of the poor attachment, they tend to become unhooked even when they are in their proper position.
As for the wearing band which is wound around the inside surface of the helmet, because of its location, it absorbs sweat and thus is often simply named a sweat band. The wearing band is removable only when used in maintenance caps, but when used in vehicle and aviation helmets, it is still tightly fixed to said helmets and cannot be removed.
An object of the present invention is to eliminate the prior art deficiencies in helmet structures used, for example, in vehicle and aviation transportation.
Another object of the present invention is to provide an improved helmet structure which contains an ear-cap, a chin-strap and a wearing band which can be conveniently attached to and removed from said helmet structure.
A further object of the present invention is to provide an improved helmet structure which is sanitary and substantially danger proof.
Other object and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter; it should be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, wherein the same reference numerals are used throughout the various views to designate identical elements, the helmet body A comprises a covering member (shell) a-1 having a given shape and made of a hard material, such as, for example, strengthened plastics, and a shock-absorbing liner a-2 having a bowl shape and made from materials such as styrene foam, and the like. The liner is secured to the inner surface of said covering member a-1. A cushion a-3 is fixed to the top, inner surface of said shock-absorbing liner a-2.
The shock-absorbing liner a-2 is shaped in the form of a bowl wherein the portion thereof receiving the user's ears is cut out and an ear-cap 4 is set therein. A wearing band 5 is removably provided inside the shock-absorbing liner a-2. Metal fittings of the chin-strap B are mounted in the ear-cap 4. Said metal fittings include a circular seat plate 1 and an enlarged head stud-like element 2 for fixing said seat plate 1 to the helmet body A. The seat plate is fixed by the stud-like element 2 to the covering member a-1 at a position where the ear-cap 4 is located. The seat plate 1 has an edge 6 integrally provided on the upper portion thereof to keep the stud-like element 2 from moving upwardly.
The stud-like element 2 is so set as to fix the seat plate 1 to the inside surface of the helmet body A. It has an enlarged head portion 2' integrally provided at the inside edge thereof to keep the key hole 3 from coming off the apertured element stud-like element 2.
The key hole apertured element 3 is made from a metal plate or a synthetic resin plate and shaped in a -form on both sides of the stud-like element 2. The central portion of the apertured element 3 is hollow and forms a stepped portion in which the lowest portion thereof is provided with a hole 7 having a diameter slightly larger than that of the stud-like element 2. A guide slot 8 connects with said hole 7 to enable the enlarged head portion 2' of the stud-like element 2 to pass therethrough.
The attachment of the apertured element 3 will now be described. First, the enlarged head portion 2' of the stud-like element 2 is placed through the guide slot 8 of the apertured element 3. The apertured element 3 then is slid upwardly to place the stud-like element 2 into the hooking hole 7 and position the enlarged head portion 2' under the stepped portion 9. Thus, when pulled in the downward direction, the apertured element 3 is tightly secured against the stud-like element 2.
Accordingly, when the chin-strap B is in use, the hooking piece 3 is prevented from moving upwardly by the edge 6 of the seat plate 1 which is positioned against the stepped portion 9 of the apertured element 3. The apertured element 3 is also prevented from coming off by the enlarged head portion 2' of the stud-like element 2. Thus, only when rotated upwardly around the stud-like element 2 can the chin-strap B be taken off. The chin-strap can be prevented from coming off whenever used along with the helmet.
FIG. 6 shows another embodiment of the present invention. On the inside surface of the hook 12 is provided a triangular enlarged head portion 12' having the top thereof arranged backwardly. The hooking piece 13 has a hooking hole 14 having almost the same shape as the enlarged portion 12' with the top portion thereof being arranged in the downward direction.
When setting the hooking piece 13 on the hook 12, the hooking piece 13 is first positioned in such a way that the hooking hole 14 corresponds to the enlarged head portion 12' of the hook 12. The chin-strap B is then moved into the using position by rotating the hooking hole 14 of the hooking piece 13 at right angles to the enlarged head portion 12' thereby securely fitting the hooking piece 13. Thus, the hooking piece 13 can be removed from the hook 12 only by aligning the hooking piece 13 with the enlarged head portion 12'.
Furthermore, the seat plate 1 and the stud-like element 2 jointly support the ear-cap 4. By setting the seat plate 1 into an opening 4' cut approximately in the central portion of a base 4', the ear-cap 4 is securely supported on the inside surface of the helmet body A. Thus, the ear-cap 4 can be removed along with the chin-strap B.
The wearing band 5 will be prepared in the following way. The shock-absorbing liner a-2 contains holes 15 provided in appropriate places thereof. A flexible head pin 16, having a cylindrical shape and made of a flexible material, for example, rubber, is set loosely into said holes 15. The outer edge of said flexible head pin 16 is fitted with a fastening plate 17 to the shell a-1 and the inner edge thereof forming the enlarged head portion 18 communicates with the wearing band 5.
The flexible head pin 16 is cylindrical in shape and made from rubber or a soft plastic. At one edge of the flexible stopping member is formed the enlarged head portion which is integral therewith. The flexible head pin 16 is loosely set in the hole 15 so that its enlarged head portion 18 is positioned inside the shock-absorbing liner a-2 and within a fastening hole 19 of the fastening plate 17.
The fastening plate 17 has the shape of a disk and is made from a hard synthetic resinous material or the like. Its central portion contains the fastening hole 19 with a diameter smaller than that of the cylindrical portion of the head pin 16.
The fastening hole 19 contains grooves 20 cut radially on the opening surface thereof so that the cylindrical portion of the flexible head pin 16 inserted through the hole 19 is so tightened as to prevent the member 16 from coming off. FIG. 2 shows four of such grooves.
As shown in the drawings, the fastening plate 17 is inserted into the fastening hole 19 so as to position the top surface of the plate 17 in the same plane with that of the shock-absorbing liner a-2 and so that the covering member a-1 is tightly fitted.
Now the attachment of the wearing band 5 will be described. The wearing band 5 is a strip or band made from a synthetic resinous material, e.g., a plastic, made in the form of a plate or cloth, and then looped around the head pin 16 to integrally form a fitting member a' having a fitting hole appropriately disposed therein.
In fitting the wearing band 5 to the helmet, the enlarged portion 18 of the flexible head pin 16 which projects inwardly from the shock-absorbing liner a-2 is deformed and expanded so as to be inserted into the hole a of the fitting member a'. When the enlarged head portion 18 is restored to its original shape, the fitting member a' is secured between the inside surface of the shock-absorbing liner a-2 and the enlarged head portion 18.
By pulling the enlarged head portion 18 of the flexible head pin 16 and pressing member 16 to make its diameter smaller than that of the fitting hole a, the fitting member a' can be removed from engagement with the head portion 18 and thus the wearing band 5 can be easily removed.
The flexible stopping member 16 can be fitted to the shock-absorbing liner a-2 in any other way than that shown in the drawings. What is important is that the member 16 must be flexibly fitted to the shock-absorbing liner a-2. Finally, a cover 10 is provided over the stud-like element 2 and the apertured element 3.
According to the present invention, both the ear-cap and the chin-strap can be freely attached to or removed from the helmet. The ear-cap can always be kept clean by washing it or changing it whenever it becomes dirty. Also a helmet can be provided with or sold with an ear-cap which sufficiently satisfies the user.
As for the chin-strap, it never comes off when the helmet is in use, and it can be readily replaced with a new one when the old one becomes worn. Furthermore, if fitted jointly with the ear-cap, the chin-strap can be used more conveniently.
Once again, the wearing band can be attached and removed by pulling and pressing the enlarged head portion of the flexible stopping member fitted to the shock-absorbing liner to make its diameter smaller than that of the hole provided in the fitting member of the wearing band. And when properly attached, the band is secured between the shock-absorbing liner and the enlarged head portion, and thus is prevented from coming out.
Thus, unlike the conventional bands, the new band of the present invention can easily be removed and changed, or dirty bands can be removed, washed, and reinstalled.
According to the present invention, no stress is applied to the hard materials forming the covering member, because the flexible stopping member is fitted to the shock-absorbing liner. Furthermore, because soft, flexible members such as rubber, are used instead of the metal heads of rivets and the like, which project inwardly from the shock-absorbing liner, the helmet of the present invention can be used with added safety.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications are intended to be included within the scope of the following claims.
