Description

  The present invention relates to a portable toilet.

  In general, when toilets in the toilet room are difficult, portable toilets are used. Such a portable toilet is configured so that a seat plate comprising a seat plate having an opening at the center and a peripheral wall suspended from the periphery of the seat plate is integrally formed of synthetic resin and can be carried. The waste pot inserted inside through the opening of the plate can be supported on the periphery of the opening of the seat plate.

In such a portable toilet, it is preferable to provide an armrest and a backrest in order to reduce the burden of the sitting operation and the rising operation or to support the back. For this reason, an armrest and a backrest are provided on the seat plate of the seat portion, and a furniture-like portable toilet that can be used as a chair is also provided other than during a toilet (for example, see Patent Document 1).
Utility Model Registration No. 2547479

  By the way, the furniture-like portable toilet described above tends to be large as a whole and is difficult to handle. Therefore, attempts have been made to make it more compact. At this time, if the backrest is moved forward to reduce the depth, when the toilet seat is rotated, the toilet seat may interfere with the backrest at a rotation angle of less than 90 degrees. In this way, if the toilet seat interferes with the backrest at a rotation angle of less than 90 degrees, the toilet seat will drop to its original position if it is released. It is necessary to hold it so that it does not fall, and the work becomes complicated.

  The present invention has been made in view of such problems, and provides a portable toilet that can hold a toilet seat body at an arbitrary rotation position that is equal to or greater than a set rotation angle with a simple structure.

  The present invention is a seat having a seat plate having an opening formed in the center and a peripheral wall suspended from the periphery of the seat plate, and is disposed on the periphery of the opening of the seat plate. A portable toilet comprising a toilet seat that is pivotally supported, a backrest and an armrest provided on the seat, and a seat that is pivotally connected to a seat plate of the seat. A stopper is provided, and when the toilet seat body is rotated, the toilet seat body is held at an arbitrary rotation position equal to or greater than a set rotation angle by direct or indirect contact friction between the stopper and the toilet seat receiver. Is.

  According to the present invention, when the toilet seat body is rotated with respect to the toilet seat receiver, the stopper provided on the toilet seat body comes into direct or indirect contact with the toilet seat receiver, the rotational moment due to the weight of the toilet seat body, the stopper and the toilet seat receiver. The toilet seat body can be held without falling if it is rotated more than the set rotation angle in which the rotational moment due to the contact friction is balanced.

As a result, if the toilet seat body is rotated more than the set rotation angle, it can be held at an arbitrary rotation position. For this reason, it is not necessary to hold the toilet seat body so as not to fall when the filth pot is taken out or set, and the operation can be easily performed with both hands. When the work is completed, the toilet seat body can be forcibly pushed down against the frictional force between the stopper and the toilet seat receiver, and can be accommodated in the toilet seat receiver.

  Here, the stopper can be individually molded and provided on the existing toilet seat body, or can be integrally molded when the toilet seat body is molded.

  The rotation angle at which the toilet seat body is held without falling may depend on the size of the filth pot, but may be of a size that does not interfere with the filth pot when taking out or setting the filth pot, and is particularly limited. Not.

  Further, the stopper may be in direct contact with the toilet seat receiver, or a contact member formed in a cross-sectional shape that is easily deformed by a thin plate may be provided on the toilet seat receiver so as to be in contact with the contact member. In this case, in order to increase the contact friction force of the stopper in response to the increase in the weight of the toilet seat body, for example, increase the contact area of the stopper or emboss the surface to increase the friction coefficient. And so on.

  Furthermore, it is preferable to provide a damper so that the toilet seat body does not suddenly collide with the toilet seat receiver when the toilet seat body is pushed down. When providing a damper, it is only necessary to provide a stopper on one side and a damper on the other side.

  According to the present invention, the toilet seat body can be held at an arbitrary rotation position that is equal to or larger than the set rotation angle with a simple configuration in which the toilet seat body is simply provided with a stopper.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an embodiment of a portable toilet 1 according to the present invention.

  The portable toilet 1 includes a seat plate 21 having an opening, a seat portion 2 having a peripheral wall 22 suspended from the periphery of the seat plate 21, and a backrest 3 and an armrest provided on the peripheral wall 22 of the seat portion 2. 4 and is mainly made of furniture in the form of furniture.

  Here, the toilet seat 5 (see FIG. 2) is disposed at the periphery of the opening of the seat plate 21 in the seat portion 2, while the seat 6 covers the opening and the toilet seat 5 on the seat plate 21. It is connected freely. Further, a filth pot (not shown) is supported on the periphery of the toilet seat 5, and by pulling out the sheet 6, the sheet 6 is laid on the seat plate 21 to cover the toilet seat 5 and the filth pot. Can sit down.

  The backrest 3 is formed of a left and right heel 31 and a headboard 32 spanned between the upper ends of the left and right heels 31, and the armrest 4 has a front end fixed to a support 41 and the upper end of the support 41. Each armrest main body 42 is fixed to the heel 31 of the backrest 3.

  As shown in detail in FIGS. 2 and 3, the toilet seat 5 includes a toilet seat receiver 51 installed along the periphery of the opening of the seat plate 21, and a pivotally supported at the rear end of the toilet seat receiver 51. The toilet seat body 52 is provided with a pin 511 projecting inwardly on the toilet seat receiver 51, while the toilet seat body 52 has a box-shaped shaft support portion formed with an insertion hole 521 a for the pin 511. 521 is provided. Then, by inserting the pin 511 of the toilet seat receiver 51 into the insertion hole 521a of the shaft support 521 of the toilet seat body 52, the toilet seat body 52 can be rotated around the pin 511 of the toilet seat receiver 51.

  Further, the shaft support portion 521 of the toilet seat body 52 is provided with a substantially P-shaped resin stopper 53 (see FIG. 4) which is located in the vicinity of the insertion hole 521a and in which the fitting hole 53a of the pin 511 is formed. On the other hand, the toilet seat receiver 51 is provided with a resin contact member 54 corresponding to the stopper 53. Here, the material of the stopper 53 is particularly preferably the same as the material of the toilet seat body 52. Specifically, the stopper 53 is also molded from polypropylene in response to the toilet seat body 52 being molded from polypropylene. Similarly, the material of the contact member 54 is also molded from polypropylene corresponding to the stopper 53.

  The length of the stopper 53 from the center of the fitting hole 53a to the free end is set slightly larger than the length from the center of the pin 511 to the surface of the contact member 54 provided on the toilet seat receiver 51. When the main body 52 is rotated around the pin 511 of the toilet seat receiver 51, the free end of the stopper 53 comes into contact with the contact member 54, and the contact member 54 is forcibly elastically deformed. That is, the contact member 54 is formed to have a substantially E-shaped cross section and is fixed to the toilet seat receiver 51, and is formed in a plate thickness and shape that are easily elastically deformed by the stopper 53.

  Therefore, when the toilet seat body 52 is rotated and the stopper 53 comes into contact with the contact member 54 provided on the toilet seat receiver 51, the rotation moment due to the weight of the toilet seat body 52 and the rotation of the stopper 53 due to the contact friction with the contact member 54. If the moment rotates beyond the balanced rotation angle, the toilet seat body 52 is held without falling. As a result, it is not necessary to hold the toilet seat body 52 so as not to fall when the filth pot is taken out or set, and the operation can be easily performed with both hands.

  When the removal operation and setting of the filth pot are completed, the toilet seat body 52 can be forcibly pushed down against the frictional force between the stopper 53 and the contact member 54 and stored in the toilet seat receiver 51.

  In the embodiment of the present invention, the stopper 53 is molded separately from the toilet seat body 52 and the stopper 53 is provided on the existing toilet seat body 52. However, the stopper 53 is integrated with the toilet seat body 52 when it is molded. You may shape | mold.

  In addition, although the contact member 54 is formed separately from the toilet seat receiver 51 and provided on the existing toilet seat receiver 51, the contact member 54 may be integrally formed by insert molding or the like when the toilet seat receiver 51 is formed. Good.

  Further, the stopper 53 may be brought into direct contact with the toilet seat receiver 51.

  As described above, since the toilet seat body can be held at an arbitrary rotation position that is equal to or greater than the set rotation angle, the workability when taking out and setting the filth pot in a portable toilet is improved. Can do.

It is a whole side view which shows the portable toilet of this invention. It is a disassembled front view which abbreviate | omits and shows the toilet seat provided in the portable toilet of FIG. 1 in the state which raised the toilet seat main body with respect to the toilet seat receiver.
