Description

Foldable Helmet

The present invention relates to a folding helmet that is easy to carry and store by minimizing the volume by dividing the helmet into a plurality of unit frames and having a folding structure while maintaining safety.

In general, a protective helmet for leisure, such as a bicycle, a kickboard, an inline skate, etc., is one of the safety equipment that a user must wear in order to minimize a head injury in a safety accident including a rollover accident.

The protective helmet consists of a helmet body and a chin strap provided on both sides of the helmet body to wear and tie the helmet body on the head.

The helmet body is composed of an exterior material having a hemispherical shape suitable for the shape of the head and an interior material installed in the exterior material to surround the wearer's head. is manufactured, and the interior material is manufactured using a foamable resin material or other materials with excellent shock absorption properties.

However, when a user wears such a protective helmet, the helmet body cannot be tailored to each user due to a different head size for each user, and in particular, since the helmet body is bulky and heavy, it is difficult to carry and store it.

Accordingly, when storing or carrying a protective helmet, the user has the inconvenience of locking it with a separate lock to prevent loss of the helmet as well as the bicycle or kickboard or having to keep it in a separate bag or carry it with a separate storage tool. When a protective helmet is stored in a space, it is difficult to secure space because it takes up a lot of space, so it is inconvenient to use even though it is essential protective equipment.

1, the folding helmet of the present invention includes a plurality of unit frames (100, 110, 120) spaced apart from each other and a band member 200 for connecting these unit frames (100, 110, 120). can be configured.

Each unit frame 100 , 110 , 120 has an outer casing 101 having a curved shape so that a space 103 is formed inside, and a shock mitigating member 102 integrally attached to the inner surface of the outer casing 101 . ) is included.

These unit frames 100 , 110 , 120 are arranged to be spaced apart from each other and are bound by the band member 200 to have a helmet shape suitable for the shape of the head.

The outer casing 101 may employ a general hard plastic material or the like.

Preferably, the outer casing 101 may include any one of acrylonitrile-butadiene-styrene resin (ABS) or fiber reinforced plastics (FRP) or polycarbonate material, and primarily protects the user's head In addition, it is possible to prevent secondary injuries caused by fragments of damaged helmets.

The shock mitigating member 102 is attached to the inner surface of the outer casing 101 to absorb and alleviate the shock caused by a safety accident.

Since the impact mitigating member 102 can select one suitable from a variety of known EPS foams or EPP foams, a detailed description thereof will be omitted.

The band member 200 is coupled to the inner surfaces facing each other of each of the unit frames 100, 110, 120 to connect the plurality of unit frames (100, 110, 120). And it is preferable to use a soft material for the band member 200, which provides flexible movement when each unit frame 100, 110, and 120 performs a folding operation.

Meanwhile, the unit frames 100 , 110 , and 120 according to an embodiment of the present invention include a central frame 100 disposed to be positioned at the center of the helmet as shown in FIGS. 1 and 2 , and the central frame 100 . It may be configured to include a pair of front frames 110 and a pair of rear frames 120 spaced apart from each other on both sides of the front and rear around the .

The central frame 100 has a relatively narrow width than the front frame 110 and the rear frame 120 to be described below and is configured in an arcuate curved structure extending along the longitudinal direction of the central part.

That is, the fewer the number of folding shapes of the helmet and the larger the area, the greater the head protection effect, because the surface tension of the hard case ABS resin has an effect of dispersing external shocks.

The central frame 100 has a function of protecting the front and back of the user, which occurs most frequently in safety accidents of bicycles or kickboards.

The pair of front frames 110 are positioned while forming a distance from both front sides of the central frame 100, respectively, to protect both frontal sides of the head.

And the pair of rear frames 120 are positioned to form a spaced apart from both rear sides of the central frame 100, respectively, to protect both temporal parts of the rear of the head.

Here, the selected one of the front frame 110 and the rear frame 120 may be configured to have a relatively larger area than the other.

It is only configured, and in some cases, it is natural that the front frame 110 may have a larger area than the rear frame 120 on the contrary.

In particular, the front frame 110 and the rear frame 120 may each have a shield shape as shown in FIG. 3 , and it is preferable that one surface facing each other be cut in the diagonal direction α.

That is, the front frame 110 and the rear frame 120 are respectively bound to both sides of the center frame 100 by the band member 200, and as shown in FIG. 4, the space portion of the center frame 100 (103) side folding operation can be carried out, the front frame 110 and the rear frame 120, which are curved surfaces, one side facing each other is cut at an acute angle, one frame having a relatively large area to the other frame A part of it can be overlapped and overlapped.

At this time, the order of the folding operation is to first fold a pair of front frames 110 having a relatively small area in the direction of the space portion 103 of the center frame 100, and then fold the pair of rear frames 120 to the pair. A portion of the front frame 110 is folded in the direction of the space portion 103 of the central frame 100 while overlapping each other.

Due to the overlapping phenomenon of the front frame 110 and the rear frame 120, as shown in FIG. 5, a pair of front frames 110 and a pair of Since the rear frame 120 is inserted and seated, it is possible to reduce the overall volume of the helmet by 60% to 70%.

In addition, the band member 200 is made of a material having an elastic force, and two or more may be coupled between each unit frame 100 , 110 , 120 .

That is, in the folding helmet of the present invention, the band member 200 has elastic force without the circumferential length adjustment means of a general helmet, so that the band member 200 contracts or expands according to the shape of the user's head, so that the helmet can be easily worn. there will be

In addition, the folding helmet of the present invention is connected to the first clip member 310 connected to one front frame 110 and one rear frame 120, the other front frame 110 and the other rear frame 120, and the second It further includes a chin strap 300 including a second clip member 320 fastened to the first clip member 310 so that the helmet can be fixed while the user wears the helmet.

In addition, although the folding helmet of the present invention is not shown in the drawings, the volume is minimized due to the folding operation of the helmet, that is, the front frame 110 and the rear frame 120 in the space 103 of the central frame 100 . ) may further include a receiving member for accommodating the unit frames (100, 110, 120) in the folded state.

The accommodating member may have a conventional bag shape in which an accommodating space is provided and an opening communicating with the accommodating space is provided on one side.
