Japanese Patent No. 3285325

By the way, the standpipe disclosed in Patent Document 1 is not provided with a deodorant valve, and the temporary toilet has a built-in deodorant valve. Therefore, if the lid is removed while the temporary toilet is not installed, there is a risk that the odor inside the standpipe will leak outside.

The present invention has been made in view of this point, and its object is to enable connection between a standpipe and a connecting pipe arranged above the standpipe, and to eliminate odors in the standpipe from the outside. To provide a pipe joint set capable of suppressing leakage into the pipe.

A pipe joint set according to the present invention is a pipe joint set for connecting a standpipe and a connection pipe arranged above the standpipe. The pipe joint set includes a support portion, a cylindrical portion, a deodorant valve, a pipe joint, and a support mechanism. The support portion is detachably supported by the standpipe in the standpipe, and is formed with a fitting hole penetrating vertically. The cylindrical portion is arranged to surround the fitting hole in a bottom view, and extends downward from the support portion. The deodorant valve is provided on the cylindrical portion. The pipe joint connects the cylindrical portion and the connection pipe when in use, and is housed in the standpipe when not in use. The support mechanism causes the tubular portion to support the pipe joint when the pipe joint is not in use. The pipe joint includes a joint fitting portion that fits into the tubular portion when in use, and a joint fitting portion that is positioned above the joint fitting portion. and a joint tubular portion disposed between the portion and the standpipe.

According to the pipe joint set, the deodorant valve can be arranged inside the standpipe by mounting the support portion inside the standpipe. Therefore, even if the standpipe and the connection pipe are not connected, for example, the odor control valve can prevent the odor inside the standpipe from leaking to the outside. Further, when the pipe joint is not used, the pipe joint is accommodated in the standpipe while being supported by the cylindrical portion by the support mechanism. Therefore, when the pipe joint is not in use, it is not necessary to secure a space for storing the pipe joint other than inside the standpipe, so the pipe joint is less likely to be lost. Further, according to the pipe joint set, the joint fitting portion of the pipe joint and the tubular portion are fitted together with the support portion mounted in the standpipe, and the joint tubular portion of the pipe joint and the connection pipe are fitted together. to connect. As a result, the standpipe and the connecting pipe can be connected by the pipe joint.

According to a preferred aspect of the present invention, the support portion is fitted to a lid frame provided at the upper end of the standpipe. The pipe joint set includes a secondary lid that fits into the fitting hole.

According to the above aspect, the deodorant valve can be arranged in the standpipe by a simple procedure of fitting the support portion to the cover frame. In addition, by fitting the sub-lid into the fitting hole of the support portion, it is possible to suppress the leakage of the odor inside the standpipe to the outside.

According to another preferred aspect of the present invention, the tubular portion has a support tubular portion extending downward from the support portion, and a connection tubular portion fitted to the support tubular portion. ing. The connection tubular portion has a connection fitting portion, a connection vertical portion, and a stepped portion. The connection fitting portion is fitted into the support tubular portion, and the joint fitting portion is fitted into the pipe fitting when the pipe joint is used. The vertical connection portion extends vertically below the connection fitting portion and has an inner diameter smaller than the inner diameter of the connection fitting portion. The stepped portion is provided between the connection fitting portion and the connection vertical portion, and the lower end of the joint fitting portion comes into contact when the pipe joint is used.

According to the above aspect, the position of the pipe joint with respect to the connection tubular portion when the lower end of the joint fitting portion of the pipe joint contacts the stepped portion of the connection tubular portion ensures that the pipe joint is securely fitted to the connection tubular portion. This is the position where the Therefore, when fitting the pipe joint to the connecting tubular portion, the pipe joint is pushed into the connecting tubular portion until the lower end of the joint fitting portion comes into contact with the stepped portion of the connecting tubular portion. can be reliably fitted to the shape portion.

According to another preferred aspect of the present invention, the pipe joint set includes a flange extending radially outward of the connecting tubular portion from the outer peripheral surface of the connecting tubular portion. The support mechanism includes a plurality of support protrusions extending radially inward of the pipe joint from the inner peripheral surface of the joint tubular portion of the pipe joint. The support projection rests on the flange when the pipe joint is not in use.

According to the above aspect, when the pipe joint is accommodated in the standpipe, the plurality of support projections are placed on the flange of the connection tubular portion. As a result, the pipe joint can be accommodated in the standpipe while being supported by the connection tubular portion.

According to another preferred aspect of the present invention, the edge of the flange is formed with grooves into which the support projections fit when the pipe joint is not in use.

According to the above aspect, when the pipe joint is accommodated in the standpipe, the support projection of the pipe joint is fitted into the groove of the flange. Therefore, when the pipe joint is supported by the connecting tubular portion, it is difficult to move the pipe joint with respect to the connecting tubular portion, and it is easy to align the pipe joint with the connecting tubular portion.

According to another preferred aspect of the present invention, two supporting protrusions are provided at positions facing each other across the center of the pipe joint in a plan view.

For example, when the support part is removed from the standpipe, it may be taken out in a state where the support part is inclined with respect to the standpipe. If the pipe joint is attached to the cylindrical portion without swinging, the pipe joint will also tilt when the support portion is tilted. Therefore, when the support portion is tilted, the pipe joint easily collides with the inner peripheral surface of the standpipe, and it is difficult to remove the support portion from the inside of the standpipe. However, according to the above aspect, since the two support projections face each other, the pipe joint can swing about the two support projections with respect to the cylindrical portion. Therefore, even when the support portion is tilted when the support portion is taken out from the standpipe, the pipe joint is less likely to be tilted, and thus the pipe joint is less likely to collide with the standpipe. Therefore, it is easy to remove the support portion from the inside of the standpipe.

According to another preferred aspect of the present invention, the deodorant valve includes an arm provided on the outer peripheral surface of the cylindrical portion, and is supported by the arm and extends in a direction perpendicular to the axial direction of the cylindrical portion. and a valve body that can be attached to the lower end of the cylindrical portion and that is swingably supported by an arm via the support shaft. In plan view, the axis passing through the two support projections and the axis of the support shaft are orthogonal.

According to the above aspect, the pipe joint swings around the axes of the two support projections when housed in the standpipe. When the pipe joint swings around the two support projections, the valve body and the support shaft swing together with the pipe joint. The support shaft is arranged outside the valve body in plan view. As a result, compared to the case where the axes of the two support projections and the axis of the support shaft extend in the same direction, the swing width of the support shaft when the pipe joint swings can be shortened. can. Therefore, when the pipe joint is swinging, the deodorant valve is less likely to collide with the standpipe.

According to another preferred aspect of the present invention, the outer peripheral shape of the flange in plan view is circular. The joint tubular portion has a cylindrical shape. The distance between the tips of the two support projections is shorter than the outer diameter of the flange. A notch through which the support projection can pass is formed in the edge of the flange.

According to the above aspect, the distance between the tips of the two support projections is shorter than the outer diameter of the flange. Therefore, when the connecting tubular portion supports the pipe joint, when the connecting tubular portion is inserted into the pipe joint from above, the support projections provided on the inner peripheral surface of the joint tubular portion of the pipe joint do not reach the connecting tubular portion. It may not be able to be inserted because it catches on the flange of the part. However, since a notch through which the support projection can pass is formed in the edge of the flange, when inserting the connecting tubular portion into the pipe joint, the support projection must be inserted through the notch of the flange. Just do it. Then, the connecting tubular portion is inserted into the pipe joint, and the pipe joint is rotated with respect to the connecting tubular portion in a state in which the supporting protrusion of the pipe joint is positioned above the flange of the connecting tubular portion. , the pipe joint can be supported by the connecting tubular portion.

According to another preferred aspect of the present invention, the deodorant valve includes a valve body that can be attached to the lower end of the tubular portion. The pipe joint set includes a sealing member that is provided on the cylindrical portion and contacts the valve body, or is provided on the valve body and contacts the cylindrical portion.

According to the above aspect, it is possible to enhance the adhesion between the cylindrical portion and the valve body. Therefore, it is possible to prevent odor from leaking through the gap between the cylindrical portion and the valve body.

According to another preferred aspect of the present invention, the deodorant valve includes a valve body that can be attached to the lower end of the tubular portion. The valve body includes a closing plate portion that closes the tubular portion when attached to the lower end of the tubular portion, and a closing plate portion that closes the tubular portion when attached to the lower end of the tubular portion. an enclosure extending at least upwardly.

According to the above aspect, water can be stored in the valve body when the valve body is attached to the tubular portion. The water stored in the valve body, together with the closing plate portion of the valve body, separates the inside of the standpipe from the outside, and plays the role of shielding the odor inside the standpipe from the outside. Therefore, it is possible to make it more difficult for the odor in the standpipe to leak outside.

According to another preferred aspect of the present invention, the deodorant valve includes an arm provided on the outer peripheral surface of the cylindrical portion, and is supported by the arm and extends in a direction perpendicular to the axial direction of the cylindrical portion. a support shaft mounted on the lower end of the cylindrical portion, a valve body supported swingably by the arm via the support shaft; a weight disposed on the side of the arm and swingably supported by the arm via the support shaft. The cylindrical portion is provided with an inclined surface that is arranged above the weight and that is inclined inward in the radial direction of the cylindrical portion downward.

For example, when the parent lid 21 is removed from the lid frame 3 , the parent lid 21 may be taken out in a state of being tilted with respect to the standpipe 2 . If the pipe joint is attached to the tubular portion without swinging, the pipe joint is also tilted when the parent cover is tilted and removed from the cover frame. Therefore, in this case, the pipe joint is likely to collide with the inner peripheral surface of the standpipe, making it difficult to remove the parent lid from the lid frame. However, in this embodiment, the two support projections 78 face each other, so the pipe joint 70 can swing with respect to the cylindrical portion 30 around the two support projections 78 . Therefore, when the parent lid 21 is removed from the lid frame 3, even if the parent lid 21 is tilted, the pipe joint 70 is less likely to tilt. Therefore, the pipe joint 70 is less likely to collide with the standpipe 2 . Therefore, the parent lid 21 can be easily taken out from the standpipe 2. - 特許庁
