BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to box glasses for underwater observation which are used for catching fish or observing underwater and can observe a wide range of underwater by a movable reflector.

[0002]

2. Description of the Related Art Underwater box glasses are used for catching and observing fish by looking into the water from the water surface. In this method, transparent glass is fitted on the bottom or side surface of a box having a required size, the glass portion on the bottom or side is sunk at least below the water surface, and water is prevented from entering the box body. It is one that can be visually observed.

[0003]

The conventional underwater box eyeglasses have a required size and are formed by simply fitting a transparent plate glass to a part of a box body, for example, a bottom surface. It has the drawback that it can only be observed from the intersection direction and cannot be seen deep underwater or far away.

SUMMARY OF THE INVENTION It is an object of the present invention to enlarge the observable range in water and to make it possible to observe the water vertically or at a desired angle from above the water surface.

[0005]

Means for Solving the Problems The present invention has been made to achieve the above object, and a transparent plate is provided in a water-tight manner in a window hole formed in a required shape and formed in a lower portion of the front surface of a box having an upper portion. Provide a protective plate that can be opened and closed outside the window hole, and swingably supports a movable reflecting mirror that adjustably bends light from the window hole at the bottom of the box, and is movable on the box. The gist is that a swing operation mechanism of the reflector is provided, and a fixed reflector for reflecting the image of the movable reflector is provided on the inner surface of the box as needed.

[0006]

The transparent plate is watertightly fitted in a window hole formed in a required size at a lower portion of a front surface of a box having a required size formed by bulging outward on both sides in a U shape. A protective plate is provided outside the transparent plate so as to be opened and closed. A movable reflecting mirror is provided at the bottom of the box so as to be swingable. A rod is bored in this movable reflecting mirror, and the operation angle of the movable reflecting mirror is adjusted via the rod by an operation lever provided on the upper part of the box. This makes the underwater range visible through the transparent plate variable, so that the visual observation angle can be arbitrarily adjusted from a short distance portion to a long distance portion of the box. Further, by providing a fixed reflecting mirror in the box, the image that can be seen becomes a normal image, and the user can look underwater directly from above the water surface, so that observation underwater can be performed reliably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment of box glasses for underwater observation. In the figure, reference numeral 1 denotes a box body of underwater observation box glasses having a required size, and the opposite side plates are swelled outward in a rectangular shape, and the box is arranged in the upstream and downstream directions of the water flow. Prevent turbulence in the front of the body,
It is possible to suppress the occurrence of water bubbles due to turbulence and to reliably perform observation in water.

In the lower part of the front surface of the box 1, a window hole 2 having a size and a shape suitable for peeking into the water is perforated, and a transparent plate (a glass plate or the like) 3 is water-tightly inserted in the window hole 2. The transparent plate 3 is provided on the outer surface of the window hole 2.
Is attached to the box 1 via a hinge 5 to prevent damage when not in use, and by oscillating the protection plate 5, that is, when not in use, the protective plate is overlaid on the transparent plate to cover the transparent plate. , And is opened and used at the time of use as shown in FIG.

A movable reflecting mirror 6 is provided at the inner bottom of the box 1 so as to be swingable by a hinge 6H, and the light incident through the transparent plate is bent by the movable reflecting mirror 6 and viewed from the upper part of the box. The light reflected by the movable reflecting mirror 6 is attached to a side end of the movable reflecting mirror or a side end of a frame to which the movable reflecting mirror is attached so that the angle of the light reflected by the movable reflecting mirror 6 can be adjusted. Then, the rod 7 is guided to the upper portion of the inside of the box, and attached to the operation lever 9. One end of the operation lever 9 is pivotally attached to the box 1 so as to be swingable, and a fixing screw 10 is provided at the other end. The fixing screw 10 passes through an arc-shaped long hole 1H formed in the box 1. Then, the fastening or loosening operation can be performed from outside the box.

The elongated hole 1H is formed in an arc shape drawn by a fixing screw mounting portion when the operating lever is pivoted about the pivot axis of the operating lever 9, so that the operating lever 9 connects the fixing screw outside the box body. Loosen, allow this head to move up and down. The operation lever swings due to the movement in the elongated hole 1H of the fixing screw, and the movable reflecting mirror descends via the rod following the movement, adjusts the angle of the reflected light by changing its mounting angle, and adjusts the angle of the reflected light. The short distance portion or the long distance portion can be seen from the upper part of the box body. The fixing screw is tightened and fixed at a predetermined mounting angle.

The box body 1 is opened only on the upper surface and is manufactured in a water-tight manner so that water is prevented from entering the box body even when at least the transparent plate is immersed in water. Hanging band B whose length is adjustable as described above.

The outer shape of the lower bottom surface of the box 1 is bent as shown in FIG. 2 so that even when water flows, the flow is rectified to prevent the water flow from being disturbed. Be able to do it.

Further, a fixed reflector is attached along the inner side surface of the box, above the window, and at a position where the image of the movable reflector is reflected. The fixed reflecting mirror has a flat mirror shape or a concave mirror shape when an image is enlarged. By doing so, even when observing from above the box, the image will be in a normal state, and the observation position can be easily observed not only vertically above the box but also from any angle obliquely above. Furthermore, this allows observation in a natural posture without looking through from above the box.

[0014]

[Effects of the Invention] The underwater observation box glasses of the present invention have a required shape, and a transparent plate is provided in a water-tight manner in a window hole drilled in a lower part of the front of the box body which is opened, and can be opened and closed outside the window hole. Provide a protective plate and swingably support a movable reflecting mirror that adjustably bends the light from the window hole at the bottom of the box body,
In addition, since the box is provided with a swinging operation mechanism for the movable reflecting mirror, it is possible to adjustably view the underwater predetermined angle from above the water surface to a farther distance than near distance, and expand the underwater observation area, Ideal for catching fish and observing underwater. Further, when the box body is submerged in water, the generation of turbulent water flow is prevented and the generation of water bubbles is suppressed, so that there is an advantage that the water can be observed in a clean state. In addition, since a fixed reflector is provided inside the box to reflect the image of the movable reflector, it is possible to easily observe in a natural posture without having to look in from the top of the box and to view normal images. It has advantages such as being visible.
