Abstract

(57) [Summary] [Purpose] The purpose is to provide a urinal structure with improved appearance and manufacturability. [Structure] A joining piece 3 formed as a separate body having a plurality of projections 4, 4, 4 at predetermined intervals on the inner circumference of a hanging portion 54 of the urinal 1.
Are joined together to form a water passage space S through which washing water passes inside the joining piece 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to the structure of the hanging portion of the urinal.

[0002]

[Prior art and its problems]

 Conventionally, the urinal 51 has a structure as shown in a side sectional view in FIG. 3 and a plan view in FIG. 4, and an upper rim 52 is formed on an upper portion of the urinal 51. A water passage 53 is formed in the front edge of the water passage 52 so as to communicate therewith, and the lower end of the water passage 53 is integrally connected to a rim 55 formed inside the hanging portion 54 protruding forward. The rim 55 has a water passage space S through which the washing water passes, and the lower surface 55a of the rim 55 has a plurality of water holes 56 through which the washing water flows down to the ball portion 57 side. .. In addition, a trap portion 58 is formed in the lower portion, and the structure is such that the water is drained through the drain portion 59 through the trap portion 58.

In such a structure, the rim 55 protrudes inward at the inner periphery of the hanging portion 54, which is unsightly, and when the urinal 51 is manufactured, when sludge is cast and molded in a mold. In addition, it is difficult to remove the mold because the rim 55 protrudes inward. Therefore, it is necessary to use a split mold, and in order to form the water passage space S well, the rim 55 part in the mold is required. It was necessary to properly adjust the amount of flesh deposited on the rim 55, which made molding around the rim 55 difficult.

[0004]

[Means for Solving the Problems]

 The present invention was devised in view of the above conventional problems, and an object thereof is to provide a urinal that is easy to form and has a clean appearance. That is, a separate joining piece having a plurality of protrusions at predetermined intervals is joined to the inner circumference, and a water passage space for passing washing water is formed inside the joining piece.

[0005]

[Function] Since the hanging part of the urinal is formed by joining a separate joining piece to the inner circumference of the urinal, it is not necessary to use a split mold as in the conventional case, and the appearance is neat. It is possible to form a water hole through which washing water can be favorably formed between the plurality of protrusions inside the joining piece.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional configuration diagram of a urinal, and FIG. 2 is an exploded perspective configuration diagram of a hanging portion and a joining piece. In the figure, the same parts as those of the conventional structure are designated by the same reference numerals.

An upper rim 52 is formed in an upper portion of the urinal 1, and a water passage 53 is formed in a communicating manner with the upper rim 52 so as to hang down toward the front edge side. It is formed up to the upper portion, and the joining piece 3 formed separately in this example is joined to the inside of the hanging portion 54, and the hanging convex portion 2 protruding upward and this joining piece 3 are joined together. A water passing space S through which cleansing water passes is formed between the and water, and a plurality of water holes 5 and 5 are formed in the lower portion of this water passing space S. The structure is such that it flows inward, passes through the trap portion 58, and is drained from the drain port 59.

In this example, as shown in the exploded view of FIG. 2, the joining piece 3 is formed separately, and a plurality of protrusions 4 are formed at a predetermined interval on the lower inside of the inclined inclined surface 3a. , 4, 4 are integrally formed, and water holes 5, 5 are formed between the protrusions 4, 4, 4. The joining piece 3 is made of the same pottery material as that of the urinal 1, and is attached to the urinal 1 in a semi-dried state and integrally joined, and then the whole is fired to form the urinal 1. In the state where the joining piece 3 is joined to the hanging convex portion 2, the lower protrusions 4, 4 and 4 come into contact with the lower portion of the hanging convex portion 2, that is, the upper edge of the ball portion 57, and a plurality of water holes are satisfactorily formed. 5, 5 can be formed.

As described above, in this example, since the joining piece 3 formed as a separate body is joined and molded before firing, the urinal body side has a conventional split mold for forming the rim portion. It is possible to easily remove the mold from the inside of the mold without the need for a mold, and manufacturing is easy. Further, unlike the conventional case, there is no need to worry about the amount of the rim inlaid, which facilitates manufacturing. Further, the joining piece 3 can be formed in an inclined shape having the inclined surface 3a, so that the inner periphery of the hanging portion 2 can be formed into a neat appearance shape with a small amount of inward projection.

[0010]

[Effect of the device]

 In the urinal structure of the present invention, a separately formed joint piece having a plurality of protrusions is joined to the inner circumference of the hanging portion of the urinal, and flush water is passed inside the joint piece. By forming the water passage space, it is not necessary to use a split mold as in the past when molding the urinal body, and there is no need to worry about the amount of rim inking, and it is easy to use in the mold. The main body can be manufactured, and the joining piece formed separately can be joined later to form the hanging portion having a good appearance shape, which has the effect of significantly improving the appearance and manufacturability.
