Description

[Detailed description of the invention] [Industrial application field] The invention can be used as a life-saving equipment for ships or as equipment for lifeboats, or as an emergency carry item for mountaineers in the event of a water or mountain disaster. This invention relates to a foldable rescue reflector that informs searchers of the location of a long-distance victim by emitting radio waves from a radar or by emitting light from a projector.

[Conventional technology]

Rescue reflectors used as life-saving equipment on ships or equipment for lifeboats are conventionally made by using metal foil with high radio wave reflectance on the smooth surface of a flat metal plate or synthetic resin plate. There are known rescue reflectors that are of a flat mirror type and have a spherical concave reflecting surface.

However, in these reflectors, the incident radio waves or irradiated light are reflected back to the searcher who is the source, so in the case of the plane mirror type reflector, it is reflected from the direction perpendicular to the reflecting surface, and in the case of the concave mirror type reflector, it is reflected from the direction perpendicular to the reflecting surface. In the case of a reflector, it is limited to cases where the light is incident from a direction parallel to the mirror axis of the reflector.

Therefore, as shown in Figures 4 and 5, it efficiently reflects radio waves or irradiation light, etc. incident from any angle toward the source, and can be folded and stored compactly, making it easy to use. Collapsible rescue reflectors that can be deployed have recently been used.

This foldable rescue reflector 1 consists of five vertical members 2, 3, 4, 5, each formed in a semicircular shape with the same radius.
6, and four horizontal members 7, 8, 9, and 10 formed in a quadrant having substantially the same radius as the vertical member. The vertical members 2, 3, 4, 5, and 6 are connected to each other in a foldable manner by abutting their linear sides, and the vertical members 2, 3, the vertical members 3, 4, and the vertical members 4, 5
and between the vertical members 5, 6, the horizontal members 7, 8, 9, 1
0 on the two linear sides of the horizontal member, the vertical member is opened up and the reflector 1 is opened.
When assembling, it is attached with a plurality of rivets 12 so as to form a right angle, and each horizontal member is provided with a folding line 13 that divides the angle formed by the two linear sides into two, and when folding the vertical member, this The horizontal members are also folded accordingly. Further, the vertical members 2 and 6 are in contact with each other when the reflector 1 is assembled, and the male member 14a and the female member 14b of the snap 14 are in contact with each other.
It is latched on.

[Problem that the invention attempts to solve]

However, in the above-mentioned foldable rescue reflector 1,
Because the vertical members 2 and 6 are assembled in contact with each other, five vertical members are required even when opening the vertical members in four directions, and an installation fee is required to attach the horizontal members to the vertical members, and it is difficult to mount them with rivets. This process takes time and effort to produce, leading to high costs. Furthermore, there is a drawback that the bent portion of the attachment allowance is weak in strength and easily peels off. Furthermore, since the bent portion of the attachment allowance is easily stretched, when the horizontal member is unfolded, sufficient tension is not applied to the horizontal member, making it difficult to expose the horizontal surface, resulting in poor performance.

Therefore, the present invention aims to reduce the cost by greatly saving the time and effort spent on manufacturing, maintains strength, and eliminates the unnecessary stacking of vertical members and installation costs, and is a folding type rescue device with excellent performance. The purpose is to provide a reflector.

[Means for solving problems]

The foldable rescue reflector of the present invention has been developed in view of the above points, and includes four vertical members of substantially the same shape each having at least one straight side, and two vertical members arranged on one straight side. It consists of horizontal members that are shaped to butt against each other. and the vertical member forms a transverse incision on the perpendicular bisector of one linear side from the opposite side of the linear side,
The linear sides are abutted to each other and are foldably and inseparably joined at the abutting portion, while the horizontal member forms cuts perpendicular to each other from the center toward the outer periphery, and one of the cuts is a long cut communicating with the outer periphery, one piece of the horizontal member separated by the long cut is provided with a locking tool, and the other piece is provided with a locking part with which the locking tool engages. . Further, the notches of the four joined vertical members and the horizontal member are fitted together, and the vertical member and the horizontal member are assembled inseparably with at least one of the long notch forming pieces of the horizontal member remaining. The locking tool and the locking device are made foldable by using the joint positions of the vertical members as pivot points, and restrict the rotation of the horizontal member at a position where the horizontal member is perpendicular to the vertical member. It can be assembled by fixing it with the parts.

[Effect]

Due to the above structure, when unfolding from the folded storage state to the use state, the vertical members are moved to positions perpendicular to each other, the horizontal members are tensioned, and the locking tool is attached to the locking part. engage.
