Description

[Detailed Description of the Invention] "Industrial Field of Use" The present invention relates to a float that is suitable for places with relatively few waves and floats by attaching a float to the lower surface of a frame member made up of a plurality of unit members.

``Prior art'' This type of conventional cage is made up of a frame of unit members and is almost fixed to a predetermined size and frame shape. And the frame shape cannot be changed freely. In addition, the frame members are floating on the water surface, and when waves occur, the frame members move up and down differently depending on the location, and irregular loads are applied, causing damage at the joints of the frame members. Therefore, the connecting portion of the frame member is required to have a required strength. Furthermore, when assembling the unit members constituting the rack onto the frame member, if the unit members cannot float and sink, the framing work may be difficult.

``Problems to be solved by the invention'' The present invention provides an ice cube whose size and frame shape can be arbitrarily changed depending on the intended use or location of the ice cube, and which allows the joints of the frame members to remain stable even when waves occur. It is an object of the present invention to provide a drawer which has sufficient strength to withstand and is easy to work when assembling the drawer by framing it with unit members.

``Means for Solving the Problems'' This invention forms a projecting joint in the form of a right isosceles triangle at both ends of a unit member with the apex being a right angle, and connects a plurality of unit members to each projecting joint. It is possible to frame a frame member of any size and frame shape by joining and connecting them, and also to make sure that the connecting part of the frame member has the required strength by connecting both outer sides of the unit member in the thickness direction of the unit member. A connecting fitting having an upright flange that protrudes to the side is fixed to a protruding joint part of a unit member, and the upright flanges are screwed together.

``Example'' As shown in FIGS. 1 and 2, a float 3 is attached to the lower surface of a frame member 2 made up of a plurality of unit members 1, and a net 4 containing live fish is suspended from the float.

As shown in FIGS. 3 and 4, the unit member 1 has an outer periphery made of, for example, a hollow extruded aluminum member 5 having a rectangular cross section, and a step board 6 is installed on the upper surface of the member and fixed by welding.

Both ends of this unit member 1 are projecting joints 7,
The apex angle of the tip 8 is a right angle, and the sides 9 of the apex angle of the tip 8 are formed to be isosceles.

A connecting fitting 10 is fixed to the outer side 9 by welding,
The connecting fitting 10 is provided with an upright flange 11 that protrudes outward from both sides of the unit member 1 in the thickness direction of the unit member 1, and as shown in FIGS. 4 and 5, the connecting fitting 10 is brought into contact with the mounting bolt 12. It is inserted into the symmetrical positions of the upper and lower upright flanges 11 and screwed with nuts 13.

By using the unit member 1 thus constructed, it is possible to construct a drawer of any size and frame shape. That is, as shown in FIG. 1, the unit members 1 can be connected to form a drawer consisting of four sections. On the other hand, as shown in FIG. 6, it is possible to make a large drawer consisting of one section with the central unit member 1 of FIG. 1 removed. Furthermore, as shown in FIG. 7, the drawer may be made into a two-section rectangular drawer by removing the two-section drawer shown in FIG. 1. Furthermore, as shown in FIG. 8, it is also possible to use a small cup consisting of one square section.

In addition, in the case where there is a vacant space at the connection point in the connection part, the connection part can be formed using a triangular connection aid 14 as shown in FIG. The connection auxiliary material 14 is formed in an isosceles triangular shape in plan view with the apex angle 15 at a right angle so as to fill the space between the unit members 1, and its outer periphery is made of, for example, a hollow extruded aluminum material 16 with a rectangular cross section. Connecting fittings 18, 18 similar to the connecting fitting 10 are fixed to the peripheral sides 17, 17 of the apex angle 15 by welding, and can be attached to and detached from the protruding joint portion 8 of the unit member 1 using bolts and nuts.

"Function" The present invention has a projecting joint 8 in the form of a right isosceles triangle whose apex angles are right angles at both ends of a plurality of unit members 1.
Since the projecting joint parts 8 are joined together and connected by screwing bolts and nuts, it is possible to construct a case of any size and frame shape. Further, since the unit members are connected by screwing the protruding portions of the mounting brackets protruding from the unit members, twisting and distortion can be sufficiently accommodated. It can sufficiently cope with the bending moment and shearing force applied to the connecting portion of the frame member due to irregular loads that move up and down differently depending on the location of the frame member, and sufficiently maintains the strength of the connecting portion of the frame member.

``Effects of the Idea'' As mentioned above, the present invention is a float that floats by attaching a float to the bottom surface of a frame member made up of a plurality of unit members. It is possible to form a frame member of any size and frame shape by joining and connecting multiple unit members at their respective projecting joints, and to reduce the thickness of the unit member. This is a case in which a connecting fitting with an upright flange that protrudes to both sides of the unit member in the horizontal direction is fixed to the protruding joint part of the unit member, and the space between the upright flanges is screwed. It is very practical as it allows you to construct a drawer with a different size and frame shape. The unit member of the present invention is composed of multiple pieces, and the ends are formed into protruding joints of right-angled isosceles triangles with the apex angle being a right angle, so they can be used for both left and right use, and are useful for framework work. There is no need to swing the unit members around to match the joints, and the framing work is easy. In addition, the connection part of each unit member is made by fixing a connecting fitting having upright flanges that protrude to both outsides of the unit member in the thickness direction of the unit member to the protruding joint part of the unit member, and screwing between the upright flanges. Since the frame members are connected together by bending and shearing forces that are applied to the joints of the frame members due to the irregular loads that occur due to waves that move up and down in different parts of the frame members, the frame members Maintain sufficient strength of the joints. Furthermore, since the molded members constituting the unit members constituting the ike are hollow members, the unit members float on the water surface, making it easier to assemble the ike.
