DESCRIPTION:
BRIEF SUMMARY
This invention relates to a helmet, preferably adapted for cyclists, but also for skateboard runners and roller skaters.
It has become popular to cycle, but unfortunately the number of bicycle accidents has increased thereby. According to an investigation of the number of accidents, in which children up to 15 years' age were involved, bicycle accidents ranked as the second greatest group. In order to reduce the risks at such accidents, therefore, helmets have come into use, which are recommended also for adult cyclists, especially those participating in the traffic in greater cities.
A helmet for cyclists, skateboard runners or roller skaters must meet certain requirements. The helmet must provide good ventilation, because its wearer advancing by his own efforts gets warm and begins to sweat more readily than a mopedist or a motor-cyclist. The helmet, furthermore, should be adjustable and of low weight. It should not appreciably screen off sound nor reduce or disturb the visual field. The inside of the helmet shall be soft. The helmet also shall be esthetically attractive and have a low price. This implies that the manufacturing costs shall be low, and the costs for distribution and storage shall be as low as possible. The lastmentioned requirement can be met when the helmet is made of plate-shaped material portions formed in a special way, which portions the consumer himself can form and fix to suitable size.
Helmets made of plate-shaped material are known previously. A construction, which is particularly suitable for children, is based on the idea that the helmet in unfolded state comprises a number of segments extending from a small central portion, which segments can be bent to the shape of the head so as to form a hood where the ends of the segments are held together by strings or bands. The width of the hood thereby can be changed as the child grows in size. With this construction, there is no continuous protective band about the head. In case of an accident, the segments easily are displaced so that the head more or less is unprotected. Especially when the child has grown in size, interspaces arise between the free ends of the segments.
In another construction, the helmet in unfolded state consists of a perforated plate of special shape with wing-shaped lateral pieces, the free edges of which after the bending of the plate over the top of the head are connected to the free lateral edges of the plate by means of a suitable glue. This helmet, thus, is adjustable only once, and its width cannot be re-adjusted.
Contrary to the aforesaid conventional helmet constructions, the helmet according to the present invention meets all requirements, which a protective helmet for cyclists, skateboard runners, roller skaters and other wearers advancing by own efforts without using motor-driven transportation means must be expected to satisfy. These requirements already are listed above.
BRIEF DESCRIPTION OF THE DRAWINGS
An advantageous embodiment of the invented helmet is described in greater detail in the following, with reference to the accompanying drawings, in which
FIG. 1 is a plan view of the tipped piece of plate-shaped material constituting the shell of the helmet,
FIG. 2 is a slightly perspective view of the tipped piece of shock-absorbing plate-shaped material which is to be attached on the inside of the shell,
FIG. 3 is a side view of the completely shaped helmet, and
FIG. 4 is a view of the helmet in FIG. 3 seen from below.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
At the embodiment shown the helmet according to the invention consists of a piece of hard flexible material, for example plastic, which piece 1 is punched out of a plate and has the form of an I with extended cross-pieces 2. Between the cross-pieces tips 3 are attached and extend extend radiated from the connection between the cross-pieces and the stem 4 of the I. At the center thereof lateral tips 5 are attached and directed one to each side. The tips and lateral tips have band-shape and are arranged symmetrically in relation to
