Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple assembling protective cap for protecting a head from an impact or the like.

[0002]

2. Description of the Related Art Hitherto, there has been a hemispherical protective cap made of polystyrene foam for simply protecting a head in light work or sports.

[0003]

However, since the above-mentioned conventional protective cap keeps its hemispherical shape, it is not only bulky and unable to be stored and stored, but also portability when not worn. It was worse, and improvement was requested.

SUMMARY OF THE INVENTION The present invention has been made to meet the above-mentioned conventional demands, and an object of the present invention is to provide a simple assembling protective cap which can be stored and stored compactly and is excellent in portability. is there.

[0005]

SUMMARY OF THE INVENTION A simple assembly type protective cap according to the present invention is made of a cushioning material such as a foamable synthetic resin and has a plurality of cap body pieces which are in a flat state as a whole and are joined to each other. A string member inserted into a hole formed in the peripheral portion of the entire cap body piece, and the string member is squeezed to draw the peripheral portions of the entire cap body piece together to assemble a substantially hemispherical cap body. It is characterized by having comprised in. Further, the plurality of cap pieces are composed of a polygonal top piece and a plurality of head side pieces radially connected from the periphery of the top piece. Further, the plurality of cap pieces are
It is also characterized in that it is composed of a strip and a plurality of bow-shaped pieces which are symmetrically connected to the left and right of the strip and are curved outward. Further, an eaves piece is joined to the cap piece.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a cap body piece, which is a plurality of pieces (six triangles in this embodiment).
And a plurality of (six in this embodiment) head-side pieces 1 "radially connected and arranged from the periphery thereof. These cap body pieces 1 are made of foamable synthetic resin. It is formed in a flat (plate) shape with a thickness of about 5 to 20 mm using a buffer material such as foamed polystyrene.

The top piece 1 'forms a polygon (a hexagon in this embodiment) as a whole, and the respective contact sides 1a are integrally joined (integral molding, joining with an adhesive, connection of an adhesive tape, etc.). Means, etc.). It is preferable that these contact sides 1a are joined so that they can be bent slightly. In the present embodiment, the outer portion of each of the contact sides 1a is separated into a front crack 1b state, but these portions may also be joined.

The head-side pieces 1 "are radially connected to each other at the periphery 1c of the top piece 1 '. A hole 1d such as an eyelet is formed on the outer periphery of each head-side piece 1". Have been. Each of these holes 1d is, as shown in FIG.
Are preferably formed at the outer side corners, but are not limited to these positions.

A string member 2 is sequentially inserted into a hole 1d formed in the head side piece 1 ". A stop piece is provided at a narrowed position (in this embodiment, a left-right symmetric position) of the string member 2. 2a are arranged, and the string member 2 is inserted therethrough.The ends of the two string members 2 that have passed the stop pieces 2a are tied to each other, and the string members 2 do not come out of the stop pieces 2a. As the detachment prevention processing, for example, a detachment stop piece may be attached to each end portion to separate them.

Reference numeral 3 denotes an eaves piece, which is joined to the outer side 1a "of the head piece 1" located on the front side of the hat. It is preferable that this joint portion is linear so that it can be easily bent. A plurality of holes 3a are also formed and arranged at appropriate intervals also in the arcuate inner side of the eaves piece 3, and as shown in the drawing,
The string member 2 is inserted.

Since the above embodiment is constructed as described above, when the string member 2 at the stop piece 2a is pulled in the direction of the arrow A, the holes 1d through which the string member 2 is inserted are sequentially drawn. A hemispherical cap body as shown in FIG. 2 is assembled.

FIG. 3 shows another embodiment of the easily assembled protective cap according to the present invention. The cap body piece 4 is mainly composed of one band-shaped piece 4 'and a plurality of bow-shaped pieces 4 ". Have been.

The strip 4 'has a width of about 20 to 50 mm, and has a length (about 300 to 400 mm) extending from the frontal part of the protective cap to the occipital area through the crown. First bow-shaped pieces 4 "-1 are symmetrically connected to the left and right sides of the strip 4 '. These bow-shaped pieces 4" -1 are mutually curved outward. On the left and right outer sides, second arcuate pieces 4 ″ -2 are symmetrically connected and arranged.
Of the first arcuate piece 4 ″ -1 is smaller than the radius of curvature of the curvature of the first arcuate piece 4 ″ -1. Further, on the left and right outer sides, third arcuate pieces 4 "-3 having a smaller radius of curvature are symmetrically connected and arranged. These arcuate pieces 4" -1, 4 "-2 and 4b"-are arranged.
Reference numeral 3 denotes a central portion which is sequentially connected. In addition, a ventilation hole 4a and a ventilation groove 4b are formed in each arcuate side 4 "so as to have air permeability, but may be omitted.

The entire peripheral portion of the cap piece 4 composed of the above-mentioned strip 4 'and the bow 4 "(the strip 4' and the bow 4").
(Longitudinal direction) is formed with a hole 4c such as an eyelet. As shown in the figure, a string member 5 is sequentially inserted into these holes 4c. 6 is an eaves piece, 6a is the hole.

Accordingly, when the string member 5 is pulled in the direction of the arrow, the holes 4c through which the string member 5 is inserted are sequentially drawn, and a hemispherical cap body as shown in FIG. 4 is assembled. In the present invention, the eaves pieces 3 and 6 may be omitted.

[0016]

[Effects of the Invention] 1) It can be compactly stored and stored in the deployed state, and is excellent in portability. 2) Assembly can be performed simply and quickly simply by pulling the string member.
