Description

The present invention can be folded and compact when not in use, is convenient without being bulky when being carried, and is not bulky even when stored, so the space required for storage can be reduced and can be assembled in a simple manner when used. It is a foldable helmet for construction, construction sites, and emergency disasters.

Solid helmets that are worn to protect the head, which is an important part of the human body, are used to protect the head, which is an important part of the human body, when working at construction sites, indoors and outdoors, and when evacuating during an emergency disaster. Therefore, it is bulky and inconvenient to carry when traveling over long distances by trains, etc. In addition, a large storage space is required to store a large amount when used in an emergency disaster. In order to solve this inconvenience, various foldable helmets have been devised in the past as in the following reference patent documents.
JP 5-140811 JP-A-8-325824 Special table hei 11-500495 JP 2000-303247 A 6-12437 ACT 7-2433 Utility model registration number 3000070

As described above, the various folding helmets devised in the past include problems, and thus have not been widely implemented and manufactured. That is, when the problems are classified: (a) A helmet of a type that becomes more compact when folded is inferior in impact strength against falling objects when assembled and used. (B) A helmet having a high impact strength against falling objects during assembly and use is not very compact when folded. (C) A helmet of a type that is compact when folded and has excellent impact strength against falling objects when assembled and used has a complicated structure and is difficult to handle, and the manufacturing cost increases. The present invention solves the problems of these foldable helmets devised in the past, becomes compact when folded, has impact strength against falling objects when used in assembly, is easy to handle, is inexpensive to manufacture, and is widely used in society. Providing a type of foldable helmet that is popular.

In order to achieve the above object, in the present invention, a quadrangular frame serving as a base, and a front plate, a rear plate, a left plate, and a right plate that are joined to each other by a coaxial rotary bearing rise up and have four walls. And a foldable helmet characterized by a box-shaped structure with a top faceplate covering it.

In addition, among the plate bodies that become the walls of the rising four faces, one set of two parallel face plate bodies out of two sets facing each other is joined by a coaxial rotary bearing, and is bent, and this upper part The top face plate is joined with a coaxial rotary bearing. Further, inside the two parallel face plates that are bent, a face plate for reinforcing the strength is joined to a quadrangular frame serving as a base by a coaxial rotary bearing.

Also, attach a hammock to the square frame that will be the base so that the human head does not directly contact the top faceplate, and attach a net so that it does not directly contact the quadrilateral frame and the four-sided plate that will be the wall. .

The foldable helmet of the present invention folds and folds each face plate body when not in use, and becomes compact by reducing the thickness. It becomes a protective shape and a helmet with impact strength against falling objects.

Embodiments according to the present invention will be described with reference to the accompanying drawings. The members constituting the foldable helmet of the present invention are the frame body 01, the front plate body 02, the rear plate body 03, the left side plate body lower member 04, the left side plate body upper member 05, and the right side plate body lower member 06 shown in FIG. The right side plate upper member 07, the top side plate 08, the left side plate 09 for strength reinforcement, and the right side plate 10 for strength reinforcement are made of hard plastic or metal, and a shock absorbing material is attached to the inside.

The front plate 02, the rear plate 03, the left side plate lower member 04, and the right side plate lower member 06 are joined to the frame body 01 by the coaxial rotary bearing 12. The left side plate body lower member 04 and the left side plate body upper member 05 are joined by the coaxial rotary bearing 12. The right side plate member lower member 06 and the right side plate member upper member 07 are joined by the coaxial rotary bearing 12. The top face plate 08 is joined to the left side plate upper member 05 and the right side plate upper member 07 by the coaxial rotary bearing 12.

In the coaxial rotary bearing 12 that is a joint portion, a portion having a convex shaft is disposed on one plate body of the joint portion, and a portion having a concave bearing is disposed on the other plate body. Each part is formed integrally with the plate.

Inside the box shape that has been set up and deployed, a hammock 13 made of a flat string knitted from synthetic fibers and a net 14 made of a string knitted from synthetic fibers are arranged on the frame body 01. These two members are attached to the frame body 01 with a removable attachment.

The chin strap 15 is attached to the frame body 01.
