Description

The present invention relates to a portable toilet.

2. Description of the Related Art Portable toilets have been known that include a toilet bowl body and legs provided on the toilet bowl body. In this type of portable toilet, the height of the toilet bowl body can be changed depending on the physique of the user. For example, Patent Document 1 discloses a portable toilet equipped with a mechanism for adjusting the length of the legs extending downward from the toilet main body.

Japanese Patent Application Publication No. 2004-097344

In the portable toilet described in Patent Document 1, the height adjusting adjuster, which is a leg structure provided at the bottom of the toilet bowl body, includes an adjuster body to which a threaded part is attached, and a nut screwed to the threaded part. have. When you turn the adjuster body, it moves up and down along the threaded part. That is, the length of the legs is adjusted and the height of the toilet body is changed.

By the way, the bottom of the adjuster main body, which is the part of the leg structure of Patent Document 1 that comes into contact with the floor, rotates together with the adjuster main body. Since the bottom part of Patent Document 1 is circular, the shape remains the same even when the adjuster body rotates, but if the part is not circular, the shape of the part located on the front side, for example, may differ depending on the rotation of the adjuster body. . In such a case, the support of the toilet main body by the legs may become unstable. Therefore, depending on the shape of the portion that contacts the floor surface, stepless adjustment may be difficult.

The present invention has been made in view of these points, and its purpose is to provide a portable toilet that can steplessly adjust the length of the legs regardless of the shape of the leg bottoms that contact the floor surface. be.

The portable toilet according to the present invention has a toilet main body and a leg bottom that makes surface contact with the floor, and has no legs provided on the toilet main body and a leg length that is the length of the legs extending from the toilet main body. Equipped with a stepless adjustment mechanism that adjusts in stages. The leg bottom is configured not to rotate when the leg length is adjusted by the stepless adjustment mechanism.

According to the portable toilet according to the present invention, when the leg length is steplessly adjusted by the stepless adjustment mechanism, the leg bottoms of the legs do not rotate. Therefore, even if the leg length is adjusted using the stepless adjustment mechanism, the leg bottoms always face in the same direction. That is, the height of the toilet main body can be changed by adjusting the leg length steplessly regardless of the shape of the leg bottom. Furthermore, since the leg bottoms do not rotate, there is a high degree of freedom in the shape of the leg bottoms.

According to a preferred aspect of the present invention, the stepless adjustment mechanism is a screw type mechanism that adjusts the leg length by rotating, and when the stepless adjustment mechanism is rotated, the leg bottom part rotates. It is configured not to.

According to the above aspect, the leg length can be adjusted by rotating the stepless adjustment mechanism. When the stepless adjustment mechanism is rotated, the bottoms of the legs do not rotate. Therefore, even if the leg length is adjusted by rotating the stepless adjustment mechanism, the bottom of the leg always faces in the same direction.

According to another preferable aspect of the present invention, the leg has a leg body portion located above the leg bottom portion and extending in the vertical direction, and the stepless adjustment mechanism is arranged between the leg bottom portion and the leg body portion. The stepless adjustment mechanism is arranged between the screenplay body portion and the leg bottom portion, and is configured to be rotatable relative to the leg bottom portion, and the interval between the screenplay body portion and the leg bottom portion is steplessly adjusted by rotating the stepless adjustment mechanism. It is configured to be adjusted by

According to the above aspect, the length of the leg itself can be adjusted steplessly by rotating the stepless adjustment mechanism and adjusting the distance between the script body and the leg bottom. At this time, since the stepless adjustment mechanism rotates relative to the leg bottom, the orientation of the leg bottom does not change. Since the distance between the script body and the leg bottom can be adjusted steplessly, the height of the toilet bowl body can be easily adjusted.

According to another preferable aspect of the present invention, the script body part has a first cylindrical part that is formed in a cylindrical shape and has a first thread groove formed on the outer circumferential surface, and the stepless adjustment The mechanism has a second cylindrical part formed in a cylindrical shape and has a second thread groove formed on an inner circumferential surface thereof to be threadedly engaged with the first thread groove, and the second cylindrical part is connected to the second thread groove. By rotating it relative to one cylindrical part, the distance between the script body part and the leg bottom part can be adjusted steplessly.

According to the above aspect, since it is only necessary to rotate the second cylindrical part, it is easy to adjust the distance between the script body part and the leg bottom part. Furthermore, since the user does not have to touch the bottom of the legs, it is possible to prevent the user's hands from getting dirty.

According to another preferred aspect of the present invention, a regulating piece is provided on the leg bottom and located inside the script body, and the distance between the leg bottom and the script body is A regulating member is provided for regulating the length from exceeding the predetermined length, and the script body portion does not come into contact with the regulating piece when the spacing is less than the predetermined length, and the script body portion does not come into contact with the regulating piece when the spacing is less than the predetermined length. It has a regulating wall portion that comes into contact with the regulating piece when it is in the position.

According to the above aspect, it is possible to prevent the leg bottom from separating from the script body due to erroneously rotating the stepless adjustment mechanism too much.

According to another preferred aspect of the present invention, the toilet main body is configured to be tiltable, and the legs include a first leg surface that is in surface contact with a floor surface when the toilet main body is not tilted, and a first leg surface that is in surface contact with a floor surface when the toilet main body is not tilted. It has a second leg surface that is located forward of the first leg surface and makes surface contact with the floor surface when the toilet main body is tilted.

According to the above aspect, even if the stepless adjustment mechanism is rotated, the positional relationship between the first leg surface and the second leg surface with respect to the toilet main body does not change. Therefore, even if the height of the toilet bowl body is adjusted, the toilet bowl body can be stably supported.

According to another preferred aspect of the present invention, the legs include a front leg and a rear leg located rearward than the front leg, and the stepless adjustment mechanism is configured to adjust either the front leg or the rear leg. It is provided only on one side.

According to the above aspect, it is easier to fine-tune the height of the toilet bowl body by using either the front legs or the rear legs, and the work is simplified. Furthermore, compared to the case where both the front leg and the rear leg are provided with stepless adjustment mechanisms, the structure can be simplified and costs can be reduced.

According to the present invention, it is possible to provide a portable toilet in which the length of the legs can be adjusted steplessly regardless of the shape of the leg bottoms that contact the floor surface.

On the other hand, by rotating the second cylindrical part 262 in a second direction opposite to the first direction with respect to the first cylindrical part 124, the distance LS between the script body part 121 and the leg bottom part 131 is narrowed. (See Figure 6). The distance LS between the script body portion 121 and the leg bottom portion 131 is, for example, in a range from 0 mm to the vertical distance between the leg side engaging portions 123 of the stepped adjustment mechanism 210 (hereinafter referred to as pitch width). Further, the interval LS ranges from, for example, the minimum interval (for example, several mm) between the script body part 121 and the leg bottom part 131 to a value larger than the pitch width. Further, the interval LS can be adjusted to a value larger than the pitch width, for example. Note that the second cylindrical portion 262 of the stepless adjustment mechanism 260 is inserted into the protruding member 135 of the leg bottom 131, but since the second cylindrical portion 262 and the protruding member 135 are not connected, the second cylindrical portion 262 The cylindrical portion 262 can rotate relative to the protrusion member 135 around the protrusion member 135 . Therefore, even if the second cylindrical portion 262 is rotated, the protruding member 135 does not rotate, and the orientation of the leg bottom 131 does not change (the second leg surface 142 is always located in front of the first leg surface 141). In this way, in this embodiment, the leg bottom 131 is configured not to rotate when the stepless adjustment mechanism 260 is rotated.
