Abstract

PURPOSE:To obtain a reflector which can be developed automatically by a simple operation, by connecting a sub-reflecting plate so as to be foldable to two pieces of main reflecting plates, of four pieces of main reflecting plates which have been connected so as to be foldable on one line, and also detaining a developing pull-string to the other two pieces of main reflecting plates. CONSTITUTION:At the time of folding, sub-reflecting plates 25, 26 are folded so as to contact closely both the surface and the reverse side of a main reflecting plate 22, and sub-reflecting plates 27, 28 are brought into contact with both the surface and the reverse side of a main reflecting plate 24. In this case, each developing pull- string 29-32 whose base end has been fixed to the sub-reflecting plates 25-28 is drawn out of through holes 21a, 23a and stretched and provided along a main reflecting plate 21 or a main reflecting plate 23. Subsequently, the main reflecting plates 22, 21 and 24 are superposed successively on the main reflecting plate 23 and folded into a semicircular contained state. At the time of development, this reflector is developed automatically to an available state by holding one pair of developing pull-strings 29, 32 and the other pair of developing pull-strings 30, 31 in one hand and the other hand, respectively, and drawing them in the separate directions to each other.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention can be used as a life-saving equipment for ships or lifeboats, or as an emergency carry item for mountaineers at the time of water or mountain distress. This invention relates to a rescue reflector that notifies searchers of the location of a long-distance victim by reflecting radio waves emitted by a victim such as radar or light emitted from a projector.

[Conventional technology]

Conventional rescue reflectors used as life-saving equipment on ships or as a bottle loader for lifeboats are made of a 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 in the form of a flat mirror with a reflective surface pasted on it, and concave mirror type rescue reflectors in which the reflective surface is formed into a spherical concave surface.

However, in order for the incident radio waves or irradiation light to be reflected back to the source, the searcher, in the case of the above-mentioned plane mirror type reflector, from a direction perpendicular to the reflecting surface,
Further, in the case of the concave mirror type reflector, the incident 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 5 to 8, the present applicant has developed a system that efficiently reflects radio waves or irradiation light, etc. incident from any angle toward the source, and that can be folded and stored compactly. Application for a foldable rescue reflector that can be easily deployed for use (Utility Application No. 1987-82087)
is being carried out.

This foldable rescue reflector 1 has six reflecting plates 11, 12, 13.14, 15.16 of approximately the same shape, four of which are vertical members 11.12, 13.14, and the remaining two The four vertical members 11, 12,
13.14 are foldably connected so that one long side of each can be gathered together and unfolded into a cross shape, and the two non-adjacent vertical members 11.13 are connected to horizontal members 15.16. , a notch is formed in each, and the notches are connected to each other so that they can be folded, and when folded, 1
The other vertical members 11, 12, 13 and horizontal members 15, 16 are all overlapped with one vertical member 14 so that they can be stored compactly.

Then, from the folded storage state (see Figure 8), the four vertical members 11, 12, 13, and 14 are first unfolded into a cross shape (see Figure 7), and then the two horizontal members 15, 76 (see Figure 6) and four vertical members 11.12.13.14
and after the two transverse members 15, 16 have been deployed to the operating condition (see FIG. 5) in which all of them touch each other at right angles, the fixture 2,
2 is used to restrict the rotation of both horizontal members 15 and 16.

[Problem that the invention seeks to solve]

However, when the above-mentioned foldable rescue reflector 1 is unfolded from the folded storage state to the use state, the four vertical members 1
It is necessary to spread the tags of 1.12, 13.14 and the two horizontal members 15.16 visually so that they touch each other at right angles, and to fix them in use, separate fixing devices are required. Since it is necessary to attach 2.2, which takes time and effort, it has been desired to develop a foldable rescue reflector that can be used with even simpler operation.

The present invention has been made in view of the above-mentioned background, and an object of the present invention is to provide a foldable rescue reflector that can be automatically unfolded into a use state with a simple operation and can be used as is.

[Means for solving problems]

As a means for solving the above problems, the present invention provides four main reflecting plates having substantially the same shape each having at least one linear side, and dividing the main reflecting plate into two equal parts perpendicular to the linear side. Equipped with four sub-reflectors of approximately the same shape as one divided by a line,
The four main reflectors have linear sides assembled and are foldably connected to each other at each linear side, and are connected to non-adjacent ones of the four connected main reflectors. Each of the above-mentioned sub-reflectors is placed on each of the front and back surfaces of the two sheets, with the right-angled corner facing the center, and one side of the two sides sandwiching the right-angled corner being perpendicular to each linear side of both main reflectors. They are connected in a foldable manner on the bisector, and the base ends of the extension drawstrings are fixed to the other side of each of the sub-reflectors at positions away from the right-angled corners. The tip side of the string is pulled on the perpendicular bisector of each linear side on the surface corresponding to each of the sub-reflectors of the remaining two main anti-reflection plates to which the sub-reflectors are not connected. It is characterized by being locked in such a way that it can be passed through.

[Function] With the above configuration, when unfolding from the folded storage state to the use state, the left and right hands should hold the tips of the two sets of unfolding drawstrings extending two by two. By holding one pair at a time and pulling them away from each other, they can be automatically deployed to use.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

The reflection 320 includes four main reflection plates 21 and 22 formed in a semicircular shape with the same radius, each forming a reflection surface on both the front and back surfaces.

That is, the insertion hole 21a is located on the perpendicular bisector of the linear side of the main reflecting plate 21.
However, insertion holes 23a are formed through each perpendicular bisector of the linear area of the main reflection plate 23, and a deployment puller whose base end is fixed to the 01 reflection plate 25 is inserted into the insertion hole 21a. The distal end side of the string 29 and the distal end side of the deploying drawstring 32 whose proximal end is fixed to the sub-reflector 28 are inserted from the facing surface to the opposite surface, and similarly, the through hole 2

〔Effect of the invention〕

As explained above, the foldable rescue reflector according to the present invention has sub-reflectors on both the front and back surfaces of the two main reflectors that are non-adjacent to the four main reflectors that are foldably connected on the - line. At the same time, the distal ends of the deployment drawstrings, which have their proximal ends fixed to each sub-reflector, are connected to the predetermined positions of the other two main reflectors to which the sub-reflectors are not connected. Since it is locked in such a way that it can be pulled out, it can be folded compactly for storage, and when in use, it can be automatically unfolded to the state of use by simply pulling the deployment drawstring. can.

In addition, since a separate fixture or the like is not required to fix the state of use, there is an advantage that the device will not become unusable due to loss of the fixture.
