Protective cap


A42B1/08 - with protection against blows (head-guards for sporting purposes A63B0071100000)

 

(57) Abstract:

The protective cap can be used both in the home and in stationary medical institutions, individuals, prone to loss of vertical stability, for example, suffering from cardiovascular diseases and mental disorders. The protective cap includes an outer edge and the inner shell. In the cavity of the knob on clearance posted by stretchy elastic harness with equidistant from each other ledges. The projections made in the form of a truncated cone and are located on the outer perimeter of the harness. The size of the gap is determined by the following relationship: C=(D-b+a)/2, where C is the clearance between the inner surface of the cavity side and the end surface of the protrusion of the loom; b - the height of the protrusion; and the diameter of the bundle; D - diameter of the cavity side. This device greatly reduces the chance of injury to the head when a person loses vertical stability. 4 Il.

The invention relates to light industry, in particular to the means of protection for the head.

Known protective cap comprising an outer shell with backsplash, filed in the basis of the shell from the inside (Blinov, L. F. and other Activities. ): Symptoms, 1958, S. is born when a person loses vertical stability.

Closest to the claimed protective cap is a protective helmet (hat) containing elastic outer shell, which is connected with the inner shell, forming together with the specified outer casing cavity in which is placed a rigid intermediate sheath with valves, and under it an extra shell, the space between the outer shell and the intermediate shell filled with fluid, and the space between the inner shell and the additional sheath is filled with a gas, for example air, nitrogen, and in a static condition the space between the intermediate and additional shells filled with fluid (A. C. USSR N 1355230, class A, 42 B 3/02).

The disadvantages of the prototype is limited use due to the inconvenience of wearing at home because of the design. In addition, the high cost due to the complexity of the manufacture and use of heterogeneous material.

The objective of the invention is to provide a protective cap, which is when a person loses vertical stability would protect the head from significant damage. In addition, one of the tasks is also reduced cost szapocznikow and the inner shell, in the cavity side with a gap placed elastic elastic harness with the tabs, and the gap is determined by the ratio

< / BR>
and the projections made in the form of a truncated cone, is located on the outer perimeter of the loom and evenly removed from each other,

where

C - the gap between the inner surface of the cavity side and the end surface of the protrusion of the loom:

D - diameter cavity side;

b - skyscraper ledge;

and the diameter of the harness.

The proposed protective cap is illustrated by drawings, where Fig. 1 protective cap, side view, a longitudinal section; Fig. 2 - placing the harness in the cavity of a side, cross-section along a-a in Fig. 1; Fig. 3 - harness, top view; Fig. 4 - harness, a section along B-B in Fig. 3.

The protective cap includes a shell 1, side 2, bent in the middle and attached on the inner side, the inner shell 3, is attached to the inner side of the outer casing 1. In the cavity of the knob 2 with a gap defined by a relation

< / BR>
placed elastic elastic harness 4 (e.g., rubber) with the tabs 5, made in the shape of a truncated cone located at the outer diameter of the harness 4 at the same distance from each other. The visor 6 is connected with the front Uch the e side 2 of the shell 1 is in contact with the protrusions 5, which are deformed, the gap is selected. Execution of the projections 5 in the form of a truncated cone causes a gradual increase in resistance to the force of the blow, which positively perceives the media beanies.

This device greatly reduces the chance of injury to the head when a person loses vertical resistance due to the introduction of flexible elastic harness with the projections made in the shape of a truncated cone. In addition, decreases the cost of cap and simplified structural design by reducing consumable material, such as cotton, cloth, etc.

The invention can be used for everyday use in the home and in stationary medical institutions, individuals, prone to loss of vertical stability, for example, suffering from cardiovascular diseases and mental disorders.

1 Protective cap comprising inner and outer shell, wherein the outer shell is made with backsplash in the cavity side with a gap posted by stretchy elastic harness with equidistant from each other, the projections made in the form of a truncated cone and located on the external Perim the capacity of the cavity side and the end surface of the protrusion of the loom; 4 D - diameter cavity side; 4 b - the height of the protrusion; 4 and the diameter of the harness.
