(Problems to be solved by the invention) By the way, in the above-mentioned cage device, since one side of the cage frame is formed of the reinforcing elastic body having a single arrangement, the fish and shellfish in the cage device are fed in the usage state. In order to prevent damage to the reinforced elastic body and to secure a stable scaffold, the rigid joint that is less affected by waves than the reinforced elastic body should be used in order to prevent damage to the reinforced elastic body. I used to work in.

However, the joint is formed of, for example, a steel pipe having a circular cross section so that it can be easily connected to the flange attached to the reinforcing elastic body having a circular cross section, which is also circular or annular. There is a problem that it is not easy to ride on the outer peripheral surface of the joint to perform feeding work and the like.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a bait device with good workability, which can easily perform feeding work or the like on a bobbin frame, particularly a joint. To aim.

(Structure of the Invention) A device of the present invention for achieving this object is a frame body in which a plurality of linearly extending hollow reinforcing elastic bodies are interconnected via a hollow rigid corner joint. In addition, the corner joint is formed with a working step having a substantially flat surface shape.

(Operation) In this cage device, when performing various operations on the cage frame, the operator does not work on the outer peripheral surface of the rigid but cylindrical joint, but on the flat work step formed there. It is possible to perform work, and the vibration of the cage frame due to waves is effectively reduced mainly by bending deformation of the hollow reinforced elastic body that constitutes each side of the cage frame, and the joint itself does not have much waves. Is not affected by

The reinforced elastic body 1 is an elastic body made of rubber or a rubber-like elastic material reinforced with organic or inorganic fibers, preferably cords thereof, and in order to generate a required surplus buoyancy, A gas chamber containing a gas such as nitrogen or air is provided. The material of the elastic body, and the number of layers and the angle of the reinforcing fiber cord thereof are selected in consideration of various requirements required for the reinforcing elastic body as the floating frame member of the living device.

FIG. 2 (a) shows a main part of a corner joint 2 used for connecting the reinforcing elastic bodies 1 to each other to form a frame frame 3 framed in a polygonal shape as shown in FIG. . The corner joint 2 is composed of two hollow joint main bodies 7 connected in a posture in which central axes intersect with each other. Each of the joint main bodies 7 is provided with a rigid flange 8 provided at each end of the reinforcing elastic body 1. A flange 9 that is airtightly connected to the joint body 7, and a connecting ear piece 10 that is provided at the other end of the joint body 7 and that forms a predetermined angle α with the plane orthogonal to the central axis of the joint body in this embodiment. . Here, since the connecting ear piece 10 is used for connection to another joint body 7, a plurality of reinforcing elastic bodies 1 are connected to each other through such a joint 2 to form a polygonal shape. It is possible to easily form the optional frame 3.
It is needless to say that the angle α can be appropriately selected according to the size of the case frame 3 to be formed and the size and number of the reinforcing elastic bodies constituting the frame 3. By the way, the rigid flange 8 is integrally bonded to the reinforcing elastic body 1 by vulcanization, for example.

Further, the corner joint 2 is formed in the joint body 7,
Compartment 11 communicating with the inside of the reinforced elastic body 1, and this compartment
A partition wall 12 adjacent to 11 and partitioned by a partition wall 12a is provided. Then, as clearly shown in FIG. 2 (a), on the outer periphery of the joint body 7 corresponding to the compartment 11, the supply and discharge of gas such as nitrogen and air to the inside of the reinforcing elastic body 1, that is, the gas chamber is controlled. An outlet 13 is provided. Furthermore, on the outer circumference of the joint body 7,
The brackets 14 are appropriately spaced apart from each other so as not to interfere with the connecting ear pieces 10, and the flat work step 15 as shown in FIG. Attach. In addition, work steps
15 may be provided one for each joint main body connected to the reinforcing elastic body, or may be provided only for a specific joint main body, and should be installed depending on the situation in which the life device is used. The location and the number of pieces shall be selected appropriately. However, since the connecting ear piece 10 for connecting the joint main body 7 to each other needs to be regularly inspected for the connection state, the inspection step is not disturbed by the fact that the work step is located on the connecting ear piece. It is better to cut it out beforehand. This is also the case when the working step is associated with the column support 19.

In addition, in the present embodiment, the first outer surface of the joint body 7 is partially
It is preferable to give the joint 2 more sufficient buoyancy by attaching a float 16 made of, for example, styrofoam, as shown in the figure.

Further, in the drawing, 17a and 17b are hooks used as handles for assembling and transporting the cage frame, and 18 are hooks as locking portions of mooring lines for mooring the cage frame, respectively, and 19 is Shows the column support.

To frame a frame that uses a corner joint provided with a work step, the joint body 7 is connected to the rigid flange 8 provided at the end of the reinforcing elastic body 1 via a suitable sealing material, The joint bodies 7 adjacent to each other are interconnected with the connecting tabs 10 also via the sealing material.
As a result, the frame frame has independent gas chambers that communicate with the compartment 11 of the joint, so that even if one gas leaks from the reinforcing elastic body that constitutes the frame, The other reinforcing elastic bodies are not significantly affected thereby. Moreover, since the compartments of the joint body 7 are sealed and connected to each other, they can also function as a float. Further, in addition to the net for its original function, a handrail, a support for a net for preventing seafood from popping out, and a mooring line are attached to the cage frame.

Next, the device of the present invention shown in FIGS. 3 and 4 will be described.

FIG. 3 has the same configuration as that of the embodiment shown in FIG. 1, but on the float 16 attached to the joint body in order to increase the work area occupied by the work step and improve its workability.
