Description

  The present invention relates to a toilet seat lift-up device and an elevating toilet seat.

  Patent Document 1 discloses a conventional toilet seat device. This toilet seat device includes a toilet seat, a toilet seat support member that pivotally supports the toilet seat, and a fixing plate that attaches the toilet seat support member to the upper surface of the toilet body. In the fixed plate, a pair of long hole-shaped through holes extending in the front-rear direction are provided at predetermined intervals on the left and right. A recess for accommodating the fixing plate is formed on the bottom surface of the toilet seat support member. A pair of pins extending inward is formed on each of the left and right inner surfaces forming the recess. Grooves are formed at the left and right ends of the fixed plate. When the toilet seat support member is housed in the recess, a pin is inserted into the groove and locked. The fixing plate is provided with a fixing mechanism for fixing the pin inserted into the groove.

  This toilet seat device is attached to the upper surface of the toilet body as follows. First, the fixing plate is placed on the upper surface of the toilet body, and the through hole and the mounting hole penetrating the left and right side of the upper surface of the toilet body are aligned. Next, a mounting bolt is inserted from above into the through hole of the fixing plate and the mounting hole of the toilet body, and a nut is fastened to the mounting bolt from below. Thereby, a fixed plate is fixed to the upper surface of a toilet bowl main body. Next, the toilet seat support member is placed on the upper surface of the toilet body in front of the fixed plate, and the toilet seat support member is moved rearward so that the fixed plate is accommodated in the recess of the toilet seat support member. As a result, the pin is inserted into the groove and fixed by the fixing mechanism. In this way, the toilet seat device can be attached to the upper surface of the toilet body.

  Since the through-hole of the fixing plate has a long hole shape, the toilet seat device can be attached to the upper surface of the toilet body in response to changes in the size of the toilet body (large toilet bowl or standard toilet bowl). That is, when the toilet seat device is attached to the large toilet, the fixing plate is fixed to the upper surface of the toilet body by inserting the attachment bolt behind the through hole of the fixing plate. Thereby, since a fixed plate is attached to the front side with respect to an attachment hole, a toilet seat support member can be attached to the front side with respect to the attachment hole of a toilet bowl main body. For this reason, the toilet seat device can be attached to the toilet body with the front end of the toilet seat protruding slightly forward from the front end of the toilet body of the large toilet.

  On the other hand, when attaching this toilet seat device to a standard toilet whose dimensions from the line connecting the centers of the left and right mounting holes of the toilet bowl to the front end of the toilet bowl are shorter than that of a large toilet, the front side of the through hole of the fixed plate The fixing plate is fixed to the upper surface of the toilet body by inserting a mounting bolt into the body. Thereby, since a fixed plate is attached to the back side with respect to an attachment hole, a toilet seat support member can be attached to the back side with respect to the attachment hole of a toilet bowl main body. For this reason, the toilet seat device can be attached to the toilet body with the front end of the toilet seat protruding slightly forward from the front end of the toilet body of the standard toilet.

  This toilet seat device can release the fixing mechanism after being attached to the upper surface of the toilet body, move the toilet seat support member forward, and lift the front end side of the toilet seat support member around the pin in the groove. Thereby, a clearance gap can be provided between the upper surface of a toilet bowl main body, and a toilet seat support member. Using this gap, it is possible to clean the rear upper surface of the toilet body exposed to the front side of the fixed plate.

  However, in the toilet seat device of Patent Document 1, since the length of the fixing plate in the front-rear direction is long, when the fixing plate is attached to a large toilet, the fixing plate largely protrudes forward from the attachment hole of the toilet body, and the front end portion of the fixing plate Approaches the rear edge of the toilet bowl formed in the toilet body. For this reason, the scattered urine or the like easily enters between the fixed plate and the rear upper surface of the toilet body. Also, even if the front end side of the toilet seat support member is lifted and a gap is provided between the rear upper surface of the toilet body and the toilet seat support member, the exposed rear upper surface of the toilet body is small, so the rear upper surface of the toilet body is good. Can not be cleaned. Further, urine or the like that has entered between the fixed plate and the upper surface of the rear portion of the toilet body cannot be easily cleaned.

  The present invention has been made in view of the above-described conventional situation, and solves the problem of providing a toilet seat lift-up device and an elevating toilet seat that can prevent the rear upper surface of the toilet body from becoming dirty and improve the cleaning performance. It is an issue that should be done.

The toilet seat lift-up device of the present invention is a toilet seat lift-up device that attaches and lifts a toilet seat device including a toilet seat and a toilet seat support member that pivotally supports the toilet seat to the upper surface of the toilet body.
It has a through-hole penetrating in the vertical direction and a first locking portion provided at a position biased to one side in the front-rear direction with respect to the center in the front-rear direction of the through-hole, without reversing the upper and lower surfaces A lower plate that can be reversed and fixed to the upper surface of the toilet body,
Each position displaced in the front-rear direction corresponding to the first locking part displaced in the front-rear direction by reversing the front-rear direction and fixing the lower plate to the upper surface of the toilet body without reversing the upper-lower surface. An upper plate to which the toilet seat support member is attached, having a second locking portion that locks to the first locking portion when lowered and lowered with respect to the lower plate,
The upper plate is attached to a position corresponding to the displacement in the front-rear direction and extends downward, and the lower plate is fixed to the upper surface of the toilet main body through the attachment hole and the through hole penetrating the toilet main body. And a toilet seat fixture that expands and contracts in the vertical direction.

  In this toilet seat lift-up device, the position where the first locking portion is displaced in the front-rear direction with respect to the attachment hole of the toilet body when the front plate is reversed and attached to the upper surface of the toilet body without reversing the upper and lower surfaces of the lower plate Placed in. The upper plate can be moved up and down at each position displaced in the front-rear direction corresponding to the displacement of the first locking portion. By utilizing the displacement of the upper plate in the front-rear direction, it is possible to deal with large toilets and standard toilets. In other words, in large toilets and standard toilets, there is a difference in the dimension from the line connecting the center of the left and right mounting holes of the toilet body to the front end of the toilet body, and the longitudinal displacement of the upper plate should be set to that dimension difference Thus, the toilet seat lift-up device can attach the toilet seat device to each of the large toilet and the standard toilet.

  At this time, since the first plate is displaced in the front-rear direction by reversing the lower plate without reversing the upper and lower surfaces, the length of the lower plate in the front-rear direction can be shortened. For this reason, it is possible to prevent the front end portion of the lower plate from greatly protruding forward from the mounting hole of the toilet body, and the front end portion of the lower plate can be separated from the rear edge of the toilet bowl formed on the toilet body. it can. Therefore, the scattered urine or the like hardly enters between the lower plate and the rear upper surface of the toilet body. When the upper plate is raised and a gap is provided between the rear upper surface of the toilet body and the toilet seat support member, the exposed area of the rear upper surface of the toilet body can be increased, and the cleaning can be performed satisfactorily.

  Therefore, the toilet seat lift-up device of the present invention makes it difficult for the upper surface of the rear portion of the toilet body to become dirty, and improves the cleaning performance.

  The lower plate is formed on the left and right sides, and has a fitting portion at a position away from the center of the through hole in the front and rear direction by a predetermined dimension, and the upper plate is formed on the left and right sides. And a fitted portion into which the fitting portion is fitted when lowered with respect to the lower plate. In this case, the upper plate can be easily positioned with respect to the lower plate by fitting the fitted portion of the upper plate to the fitting portion of the lower plate.

  The through hole may be a long hole extending in the front-rear direction. In this case, tolerances in the manufacturing process of the toilet body can be accommodated. In particular, when the toilet body is made of earthenware, a tolerance of ± 20 mm is expected from the line connecting the centers of the left and right mounting holes of the toilet body to the front end of the toilet body. For this reason, the through hole is preferably a long hole of about 50 mm in consideration of the insertion part of the toilet seat fixture. If it does in this way, when this toilet seat lift up apparatus attaches a toilet seat apparatus to the upper surface of a toilet bowl main body, it can finely adjust so that the front end of a toilet seat may protrude ahead slightly from the front end of a toilet bowl main body.

  The lower plate may have a mark formed along the through hole and indicating a center position of the through hole in the front-rear direction. In this case, the reference position for inserting the toilet seat mounting tool into the through hole can be easily recognized. For this reason, the toilet seat lift-up device can be easily attached to the toilet body.

  The compression coil spring 53 is housed between the inner peripheral surface of the through hole of the cylindrical member 52 and the outer peripheral surface of the second shaft portion 51 </ b> B inserted through the through hole of the cylindrical member 52. The compression coil spring 53 applies an elastic force in the direction in which the shaft member 51 is raised. Thus, the toilet seat mounting tool 50 is formed so that it can expand and contract in the vertical direction.

  The toilet seat fixture 50 is attached so as to extend downward from the upper plate 40 by screwing the bolt B1 with the upper plate 40 sandwiched between the head 51C of the shaft member 51 and the washer W1 through which the bolt B1 is inserted. Further, the toilet seat mounting tool 50 inserts the washer W2 inserted from the lower end of the cylindrical member 52 through the cylindrical member 52 through the through hole 31A of the lower plate 30 and the mounting hole 3 penetrating the toilet body 1A, 1B. Then, by screwing the nut N, the lower plate 30 can be fixed to the upper surfaces of the toilet main bodies 1A and 1B.

  Using the toilet seat lift-up device 20 configured in this way, as shown in FIGS. 2 and 4 to 8, when the toilet seat device 10 is attached to the toilet body 1 </ b> A of a large toilet, As shown in FIG. 3 and FIG. 9 to FIG. 13, the case where the toilet seat device 10 is attached to the toilet body 1 </ b> B of a standard toilet to constitute a lift toilet seat will be described.

  When attaching the toilet seat device 10 to the toilet body 1A of the large toilet, as shown in FIGS. 2 and 3, compared to attaching the toilet seat device 10 to the toilet body 1B of the standard toilet, The toilet seat device 10 is attached to the front side with respect to the hole 3. That is, when attaching the toilet seat device 10 to the toilet body 1A of the large toilet (see FIGS. 6 and 7), compared to attaching the toilet seat device to the toilet body 1B of the standard toilet (see FIGS. 11 and 12), The upper plate 40 is attached to the front side with respect to the attachment hole 3. For this purpose, as shown in FIGS. 5 and 10, the lower plate 30 is fixed to the upper surface of the toilet body 1 </ b> A, 1 </ b> B by inverting the front and back without inverting the upper and lower surfaces.

  In each case where the lower plate 30 is fixed to the upper surface of the toilet body 1A, 1B by inverting the upper and lower surfaces without reversing the upper and lower surfaces, the cylindrical member of the toilet seat mounting tool 50 is marked on the mark 35 indicating the center position in the front-rear direction of the through hole 31A 52, the cylindrical member 52 is inserted through the through hole 31 and the mounting hole 3 penetrating the toilet body 1A, 1B. Then, it inserts from the lower end of the cylinder member 52, clamps the washer W2, and screws in the nut N.

  When the lower plate 30 is fixed to the upper surfaces of the toilet main bodies 1A and 1B in this way, the first locking portions 33 arranged side by side before and after the lower plate 30 is reversed are 30 mm from the mounting hole 3. Displace in the front-rear direction one by one. That is, when the lower plate 30 is attached to the toilet main body 1A of the large toilet, each first locking portion 33 is 30 mm away from the attachment hole 3 as compared with the case where the lower plate 30 is attached to the toilet main body 1B of the standard toilet. Can be displaced forward.

  Further, since the reference position through which the cylindrical member 52 is inserted into the through hole 31 can be easily recognized by the mark 35, the toilet seat lift-up device 20 can be easily attached to the toilet body 1A, 1B. Moreover, each 1st latching | locking part 33 can be displaced 30 mm at a time in the front-back direction reliably.

  Since the first locking portion 33 is displaced in the front-rear direction by inverting the lower plate 30 without inverting the upper and lower surfaces, the length of the lower plate 30 in the front-rear direction can be shortened. For this reason, it is possible to prevent the front end portion of the lower plate 30 from greatly protruding forward from the attachment hole 3 of the toilet main body 1A, 1B, and the front end portion of the lower plate 30 is formed on the toilet main body 1A, 1B. It can be separated from the rear edge of the bowl 2. Therefore, the scattered urine or the like is less likely to enter between the lower plate 30 and the rear upper surface of the toilet body 1A, 1B. Further, when the upper plate 40 is raised and a gap is provided between the rear upper surface of the toilet main body 1A, 1B and the toilet seat support member 13, the area of the exposed rear upper surface of the toilet main body 1A, 1B can be increased. It can be cleaned well.

  Therefore, the toilet seat lift-up device 20 of the embodiment makes it difficult for the upper surfaces of the rear portions of the toilet main bodies 1A and 1B to become dirty, and improves the cleanability.

  After attaching the lower plate 30 to the toilet main body 1A of the large toilet or the toilet main body 1B of the standard toilet, the upper plate 40 is positioned with respect to the lower plate 30 as shown in FIGS. 6 to 8 and FIGS. At the same time, the upper plate 40 is lowered relative to the lower plate 30 to lock the first locking portion 33 and the second locking portion 43.

  That is, the bolt B1 is inserted from above the elongated hole 46A of the upper plate body 41 through the washer W1. The bolt B1 inserted through the long hole 46 is temporarily tightened into a screw hole 51F formed in the head portion 41C of the shaft member 51 of the toilet seat mounting tool 50.
