Description

  The present invention relates to a toilet bowl for a temporary toilet installed in various places such as a public place, a construction site, an event hall, a parking lot, a disaster-stricken area, and the like. It relates to an integrally formed toilet bowl.

Patent Document 1 describes a toilet bowl of a temporary toilet which is made of a plastic blow-molded body and has a closed cross-section (pipe-like) grip integrally formed at four corners. In this toilet tank, the positions of the mold split surfaces at both ends in the front-rear direction are set to positions close to the bottom surface (height of 1 to 10 cm from the bottom surface), and the expansion of the parison during blow molding is It becomes smaller on the bottom side of both ends in the direction, and the thickness of the bottom surface does not become too thin. Therefore, when installing and moving the stool, even if you hold the grip in either the front or back direction to lift the stool (including the case where a box or the like is fixed to the stool) and drag it on the ground, It is prevented that the bottom of the toilet tank is damaged and a hole is made.
Moreover, in the toilet bowl of patent document 1, the said mold split surface is set to the up-down direction middle part (center part) of a grip.

JP 2014-147479 A

In the toilet tank of Patent Document 1, the positions of the mold split surfaces at both ends in the front-rear direction are set to positions close to the bottom surface (height of 1 to 10 cm from the bottom surface), and four corners (left and right end positions at both end portions in the front-rear direction). A mold split surface is set in the middle part (center part) in the vertical direction of the grip formed in the above. For this reason, the position of the middle part (center part) of the up-down direction of the grip becomes a height of 1 to 10 cm from the bottom surface (or the ground) of the toilet bowl.
However, when the grip is close to the ground in this way, it is difficult to grip the grip and lift the burden on the body when holding the grip with both hands and lifting the entire toilet or temporary toilet. Alternatively, workability is poor when a hook-like tool or rope is inserted into the grip to lift the toilet.

  The present invention has been made in view of the above-described problems of the prior art. The positions of grips formed at the four corners of the toilet tub are slightly raised from the bottom surface (ground) of the toilet tub, The purpose is to reduce the burden on workers and improve workability when installing and moving toilets.

The toilet of the temporary toilet according to the present invention is made of a plastic blow molded body, grips with a closed cross section are integrally formed at the four corners, and the positions of the mold split surfaces at both ends in the front-rear direction are set at positions close to the bottom surface, The mold split surface of the grip is set at the lower end of the grip. ,
Further, the toilet bowl of the temporary toilet according to the present invention is made of a plastic blow molded body, and grips with a closed cross section are integrally formed at the four corners, and the positions of the mold split surfaces at both ends in the front-rear direction are set to positions close to the bottom surface. The mold split surface inside the grip is set at the lower end of the grip. In this case, the position of the mold dividing surface outside the grip is arbitrary, and may be set above the center in the vertical direction of the grip, for example.
As described above, the present invention is applied to a toilet tank in which the positions of the mold split surfaces at both ends in the front-rear direction are set to positions close to the bottom surface. In that case, it is preferable that h ≦ H / 3, where H is the height of the toilet tub and h is the height from the bottom surface of the mold split surface at both front and rear ends of the toilet tub.

The toilet bowl of the temporary toilet according to the present invention is configured by installing the mold dividing surfaces of the grips formed at the four corners at the lower ends of the grips, even if the positions of the mold dividing surfaces at the both ends in the front-rear direction of the toilet tank are the same. The position of the grip (height from the bottom of the toilet tub) can be increased. The grip position is high even if it is 1 or 2 centimeters, so it is easy to grasp the grip and lift it on the body when lifting the stool (including when a box is fixed to the stool) with both hands. The burden is reduced. Also, workability is improved when a hook-like tool or rope is inserted into the grip to lift the toilet.
At the temporary toilet rental site, one person often loads dozens of temporary toilets onto a truck and installs them at a fixed position, and raising the position of the grip as much as possible reduces the burden on the operator's body and improves workability. It is very beneficial in terms of improvement.
The present invention is particularly effective when applied to a stool (a stool having a low grip installation height) in which the positions of the mold split surfaces at both ends in the front-rear direction are set close to the bottom surface.

It is a perspective view of the toilet tank of the temporary toilet which concerns on this invention. It is the top view (a) of the same toilet tank, and a side view (b). It is a figure which shows the positional relationship of the cross section of a grip, and a metal mold | die division surface.

Hereinafter, the toilet bowl of the temporary toilet according to the present invention will be described with reference to FIGS.
A toilet tub 1 (see FIG. 1) according to the present invention has a substantially square shape in plan view, a main body (tank portion) 2 in which filth is accommodated, four grips 3 formed at four corners of the main body 2, and a main body. The two grips 4 are formed on the left and right side surfaces, and the ground bumper 5 is formed on the front end of the main body 2, and are integrally formed by plastic blow molding.

The main body 2 has a step 6 that is one step lower on the front side, a top wall 7 (including the step top wall 7a), a bottom wall 8, left and right side walls 9, 9, and a front wall 11 (step front wall 11a). 4), a toilet wall 13 is formed at a substantially central portion of the top wall 7, and a pumping hole 14 is formed at the rear end of the top wall 7. Reference numeral 15 (FIG. 2A) denotes a lid for the scooping hole 14.
The front and rear ends of the bottom wall 8 are inclined upward (inclined bottom walls 8a and 8b), the inclined bottom wall 8a is connected to the lower end of the step front wall 11a, and the inclined bottom wall 8b is connected to the lower end of the back wall 12. Connected. The front end and the rear end of each side wall 9 are inclined inward (inclined side walls 9a, 9b), and the inclined side wall 9a constitutes step 6 together with the step top wall 7a, the step front wall 11a, etc. The rear end of the wall 9 b is connected to the back wall 12.

  Solid plate-like fastening seats 16 (a total of four) are formed substantially horizontally on the same plane as the top wall 7 at two locations on the left and right sides of the toilet 1 respectively, and are attached to each fastening seat 16. A hole 17 is formed. Under each fastening seat 16, a concave groove 18 reaching the lower end is formed in the side wall 9 in the vertical direction. A floor panel (not shown), a toilet bowl and a box (not shown), a toilet bowl and a box (not shown) are arranged on the top wall 7 (excluding the step top wall 7a) of the toilet tub 1 and are fastened by bolts using the fastening seats 16 and the holes 17. It can be fixed to the tank 1 and a temporary toilet can be assembled.

The grip 3 is formed on the inclined side walls 9 a and 9 b at the four corners of the main body 2. Both ends of each grip 3 are connected to the inclined side walls 9a and 9b, respectively, and a gap 19 is formed between the inclined side walls 9a and 9b so that it can be grasped by hand or hooked or hooked.
The grip 4 is formed at a substantially central portion on the side surface of the main body 2. Concave grooves 21 and 21 are formed in the side walls 9 and 9, both ends of the grip 4 are connected to the side walls of the concave grooves 21 and 21, and a gap 22 is formed between the bottom wall of the concave groove 21 in the same manner as the grip 3. Is formed. The grip 4 is formed at a slightly higher position than the grip 3 (the height from the bottom surface is large).
Both the grips 3 and 4 have a closed cross-sectional shape, and the internal space communicates with the internal space of the main body (tank portion) 2).

  The ground bumper 5 protrudes forward in the vicinity of the lower end of the step front wall 11 a and is integrally formed with the main body 2. The ground bumper 5 includes a plate-shaped solid portion 5a having a narrow width connected to the step front wall 11a and a hollow portion 5b having a closed cross section formed on the front side thereof. The step front wall 11a of the toilet 1 is closed, and the internal space of the main body (tank portion) 2 and the internal space of the hollow portion 5b do not communicate with each other.

  FIG. 2B shows the mold dividing surface 23 by a one-dot chain line. The mold parting surface 23 is set horizontally at the center height of the ground bumper 5 on the front side of the toilet tub 1 (step front wall 11a side). When the mold dividing surface 23 on the side of the toilet bowl 1 (side walls 9 and 9 (including the inclined side walls 9a and 9b) side) is viewed in order from the front side, the mold dividing surface 23 is an inclined side surface in the range d1. The wall 9a and the grip 3 on the front side are set horizontally at the same height, and the height matches the height of the lower end of the grip 3 on the front side.

  The mold parting surface 23 is subsequently set to be inclined upward in the range d2, is set horizontally to the height of the lower end of the fastening seat 16 on the front side in the range d3, and is inclined downward in the range d4. In the range d5, set to be horizontal at the center height of the grip 4, set to be tilted upward in the range d6, and level in the range d7 to the height of the lower end of the fastening seat 16 on the rear side. Is set to be inclined downward in the range d8. Further, the mold dividing surface 23 is set horizontally at the same height on the inclined side wall 9b and the rear grip 3 in the range d9, and the height matches the height of the lower end of the rear grip 3. ing.

  Both ends in the front-rear direction of the toilet 1 (main body 2), specifically, the front side (step front wall 11a side) and range d1 of the toilet 1 and the back side (back wall 12 side) and range of the toilet 1 At d9, the mold dividing surface 23 is set at a position relatively close to the bottom surface, so that the bottom wall 8 (including the inclined bottom walls 8a and 8b) and the thickness in the vicinity thereof at both ends in the front-rear direction of the toilet 1 are provided. Becomes relatively thick (the degree of thinning is small). In addition, the mold splitting surface 23 in the range d5 where the grip 4 is formed is set at a higher position than the ranges d1 and d9. The higher the position of the grip 4, the more it is applied to the body. The burden can be reduced, workability such as movement of the toilet 1 is improved, and even if the wall of the bottom wall 8 is slightly thinner at the center in the front-rear direction, there is a problem compared to both ends in the front-rear direction. This is because it is difficult to occur.

As described above, in the range d1, the inclined side wall 9a and the mold split surfaces 23 of the front grip 3 are both set to the height of the lower end of the front grip 3, and in the range d9. The inclined side wall 9b and the mold split surfaces 23, 23 of the rear grip 3 are both set at the height of the lower end of the rear grip 3.
Here, the positional relationship between the cross section of the grip 3 and the mold dividing surface 23 (PL) is shown in FIG. When the mold split surface PL is set to the same height, the grip 3 is compared with the conventional grip 25 (FIG. 3A) in which the mold split surface PL is set at the center of the grip. Can be formed at a higher position.

  FIG. 3C shows an example in which the mold split surface PL of the grip 26 is set at a position different from that in FIG. The mold split surface PL of the grip 26 is set to the height of the lower end of the grip 26 on the inner side (the inclined side wall 9a side) (the mold dividing surface of the inclined side wall 9a is set to the same height). On the outside, it is set near the upper end of the grip 26. Also in the case of the mold split surface PL of this form, the grip 26 is located at the same high position as the grip 3 as compared with the conventional grip 25 (FIG. 3A) in which the mold split surface PL is set at the center of the grip. Can be formed. The grip 26 has an advantage that the wall thickness is relatively equal to that of the grip 3 and higher grip strength can be secured. In the case of the mold split surface PL in this form, the mold split surface outside the grip is preferably set in a range from the center in the vertical direction of the grip to the upper end (range D shown in FIG. 3C).

  In addition, in the main body 2 of the toilet tub 1, the height from the bottom surface of the mold split surface 23 at both ends in the front-rear direction (where the grip 3 is formed) (the bottom wall 8 (including the inclined bottom walls 8a and 8b)). In general, when h is the height from the lower surface of the mold to the mold splitting surface 23) and H is the height of the toilet bowl (the maximum height from the lower surface of the bottom wall 8 to the top surface of the top wall 7), In other words, by setting h <H / 2, the thickness of the bottom wall 8 can be made relatively thick (the degree of thinning is small) (for heights h and H, see FIG. 2B). However, in order to increase the thickness of the bottom wall 8 at both ends in the front-rear direction of the toilet tank 1 (in order to reduce the degree of thinning), it is actually preferable that h ≦ H / 3, and h ≦ More preferably, it is H / 4. On the other hand, in order to reduce the burden placed on the body during installation and movement of the toilet (including a box fixed to the toilet) and improve workability, the grip height should be kept as low as possible Is good. The height of the mold parting surface 23 may be determined in consideration of the above points.
