Abstract

<P>PROBLEM TO BE SOLVED: To provide a bucket which is extendable and useful. <P>SOLUTION: A cylindrical outer body is provided, which is opened at its top and bottom parts, and has an inclined side surface designed to make the diameter of the cylindrical outer body smaller toward its bottom part from its top part. On the other hand, the inner body is also provided, which is opened at its top part and is closed at its bottom part, and has the same inclined side surface as the outer body. The upper end diameter of the inner body is set larger than the lower end diameter of the outer body. The bucket is characterized by the combination of the inner body and the outer body. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a bucket that can be expanded and contracted during use by a combination of an outer body and an inner body.

  Conventionally, various buckets have been used a lot, but they were produced by integral molding, and as shown in the present invention, two objects can be used in combination and can be expanded and contracted. Is not currently found.

As described above, conventional buckets are integrally molded products, and are mainly round or square. Usually, a handle is provided so that rotation is possible, and it carries with this handle. It is often used with a liquid such as water, and the amount varies depending on the application. Since these buckets are integrated, a storage space suitable for the bucket is required for storage when not in use. In addition, when using a small amount, it is desirable to prepare a small-sized bucket separately, but there are many cases where a small amount of water is put into a large bucket and a more convenient means is required.
The present invention was invented in order to solve the problems related to the conventional bucket as described above, and a new and useful means capable of clearing the above-mentioned problems by using the two-piece type. It is intended to provide.

The present invention has the following configuration as means for solving the problems.
That is, while opening the upper and lower parts and providing a cylindrical outer body having an inclined side surface having a smaller diameter from the upper end to the lower end, on the other hand, providing an upper open bottomed inner body having the same inclined side surface as the outer body The upper end outer diameter of the inner body is made larger than the inner diameter of the lower end of the outer body, and the above inner body and outer body are combined. The present invention is a telescopic bucket having the above-described configuration. The outer body and the inner body may be configured as hollow horns.

  According to the present invention, the inner body is positioned in the outer body, the inner body is movable in the outer body, and the outer body and the inner body have the same inclined side surface, and the inner body upper portion with respect to the outer body lower inner diameter. Because the outer diameter is large, both the outer body and the inner body can be used when the amount of water is large, and the inner body can be shrunk when the amount of water is small. I can do it. Useful articles can be provided.

Hereinafter, embodiments of the present invention will be described.
In the figure, reference numeral 1 denotes an outer body, which is a substantially cylindrical body made of a synthetic resin having an appropriate thickness, and its upper portion is curved outward to form an edge portion, and a perforated handle support portion 2 is integrally formed below the edge portion. Molded.
Reference numeral 3 denotes a rod-like semicircular handle, and an end portion thereof is inserted into a hole of the handle and is rotatably supported. The handle and the handle support structure are the same as a commercially available bucket.
The upper and lower portions of the outer body are open and have inclined side surfaces that extend from the upper large diameter portion to the lower small diameter portion. Reference numeral 4 denotes an inner body, which is an upper open inclined cylindrical body having an approximate outer diameter with the outer body and is bottomed. The upper end outer diameter of the inner body is slightly larger than the lower end inner diameter of the outer body. The inner body is located in the outer body, and the mutual positional relationship is variable. Therefore, as shown in FIGS. 2 and 3, the shape changes.
Next, the use of the present invention will be described.
When using the bucket as a whole, fill the bucket with more than half its volume of water and lift it with the handle to move the inner body downward along the outer body due to the weight of the water. Since the inner body upper end outer diameter is larger, the inner body is pressed and held in the outer body as shown in FIG. 5 to prevent water leakage, and can be used in the same manner as a general bucket.
When using a small amount of water, use an appropriate amount of water in the internal body as shown in FIG. Since the distance from the upper edge of the inner body to the bottom is small, it can be used as a small-sized bucket, and it is easy to put a hand in the bucket. When not in use, the storage space can be reduced by using the state shown in FIG. In order to shrink the bucket after use, the outer body is pressed from above, and the mutual pressure is released by the movement of the inner body with respect to the outer body.

Although the present invention has been described above, the present invention is characterized in that it can be expanded and contracted with a simple structure. Since conventional buckets do not have this expansion / contraction function, they cannot be used in a compact form and lack convenience in use.
However, in the present invention, various convenient buckets are obtained.
In the above-described example, both the outer body and the inner body are formed of a cylindrical body. However, instead of this, a hollow rectangular body may be used. As described above, the present invention can be used and stored in a contracted state, and this feature can be exhibited particularly when loaded and transported in a vehicle.
As described above, a more useful bucket can be provided by the present invention.
