 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a toilet A in which the toilet mounting apparatus 1, 1 ′ according to the present invention is used. Toilet A has a toilet body B fixed on the floor (not shown), and a rear end portion of the toilet body B which is rotatable in the vertical direction via mounting devices 1 and I at the rear of the upper surface of the toilet body B. It has a supported toilet seat C and a toilet lid D.

 As shown in FIGS. 1 and 2, the device main bodies 2 and 2 of the mounting devices 1 and I are arranged and fixed to the rear of the upper surface of the toilet body B in the left-right direction as described later. Support holes 21 and 21 extending in the horizontal direction are formed on the opposing side surfaces of the device main bodies 2 and 2 so that their axes are aligned with each other. One end of a hinge device (hinge means) H is inserted into each of the support holes 21 and 21 so as not to rotate. The hinge device H has the following structure, but a hinge device having another structure or a simple shaft may be used.

 Since the hinge device H has a known structure, it will be briefly described that a hinge body I having a bottomed cylindrical shape, a base end portion is rotatably inserted into the hinge body I, and a distal end portion is hinged. And a hinge axis J protruding outside from the opening of the main body. The hinge main body I has a base end (an end on the bottom side) non-rotatably fitted into the support hole 21 of the apparatus main body 2. The tip of each hinge body I, I protrudes from the support hole 21, 21 and is connected to the connecting cylinder C1, C2 provided at the rear end of the toilet seat C with their axes aligned. Each is rotatably introduced. Thus, the toilet seat C is supported by the toilet body B so as to be able to rotate upward and downward. The hinge shaft J of the hinge device H attached to the attachment device 1 'is non-rotatably fitted to the connecting cylinder portion C2.

At the rear end of the toilet lid D, connecting cylinders Dl and D2 are provided with their axes aligned. ing. A hinge shaft J of a hinge device H supported by the mounting device 1 is non-rotatably fitted to one of the connection cylinder portions (the connection cylinder portion on the left side in FIG. 2) D1. One end of the connecting tubular portion C2 of the toilet seat C is rotatably fitted to the other connecting tubular portion D2. Thus, the toilet lid D is attached to the toilet body B so as to be rotatable upward and downward about the same rotation axis as the toilet seat C.

 Inside the hinge body I, there is provided a rotation urging means including a damper mechanism and a coil spring.

(Both not shown) are provided. When the toilet seat C or the toilet lid D rotates from the open position (the position about 110 ° upward from the closed position shown in Fig. 1) to the closed position, the hinge shaft moves in one direction ( When rotating the toilet seat C and the toilet lid D in the same direction), restrict the rotation speed of the hinge shaft to a low speed. Therefore, the toilet seat C and the toilet lid D rotate at a low speed when closing and rotating. The damper mechanism allows high-speed rotation when the hinge shaft rotates in the other direction. Therefore, the toilet seat C and the toilet lid D can rotate at a high speed during the opening rotation.

 The rotation urging means incorporated in the hinge body I of the hinge device H urges the toilet seat C upward through the hinge shaft: [. The urging force of the rotation urging means is smaller than the rotational moment due to the weight of the toilet seat C while the toilet seat C rotates by a predetermined angle from the closed position, for example, from 70 to 80 ° from the closed position. However, when the toilet seat C rotates more than that, the rotational moment due to the weight of the toilet seat C becomes larger. Therefore, when the toilet seat C is located in a predetermined angular range from the closed position and is in a state where it can freely rotate, the toilet seat C rotates to the closed position by its own weight. On the other hand, when the toilet seat C is out of the predetermined angle range, the toilet seat C is automatically opened and rotated to the open position by the rotation urging means. The toilet lid D is caused to behave similarly to the toilet seat C by the rotation urging means built in the other hinge device H.

 Next, the toilet mounting device 1, I will be described. However, since the mounting device 1 is configured to be symmetrical with respect to the mounting device 1, only the configuration necessary for the mounting device 1 'in relation to one of the mounting devices 1 will be described. The same components as those of the mounting device 1 are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIGS. 2 to 5, the mounting device 1 has a mounting shaft 3 and a lock member (engaging member) 4 in addition to the device main body 2. The mounting shaft 3 has a cross section as shown in Fig. 5. A large-diameter shaft 31 occupying a large part of the mounting shaft 3 and a small-diameter shaft 3 2 integrally connected to one end surface of the large-diameter shaft 31 The small diameter shaft portion 32 has an annular contact portion 33 integrally formed on the outer peripheral surface of the front end portion. The large-diameter shaft portion 31, the small-diameter shaft portion 32, and the contact portion 33 are formed so that their axes are aligned with each other. The large-diameter shaft portion 31 and the contact portion 33 have the same outer diameter. The lower surface 33 a facing the small-diameter shaft portion 32 side (lower side) of the contact portion 33 is a plane orthogonal to the axis of the mounting shaft 3. As shown in FIG. 2, the mounting shaft 3 is arranged on the left side of the rear end of the upper surface of the toilet body B with its axis line extending vertically. The mounting shaft 3 of the mounting device is disposed at the same position in the front-rear direction with respect to the mounting shaft 3 of the mounting device 1, and is separated in the left-right direction to the right in FIG. The base end ′ (lower end) of the large-diameter shaft portion 31 of the mounting shaft 3 is embedded and fixed in the toilet body B. The mounting shaft 3 is detachably inserted into the through-hole formed in the toilet body B, and is attached to and detached from the toilet body B by screwing a nut to the lower end protruding downward from the through-hole and tightening. You may make it attach as possible. Also, the mounting shaft 3 may be attached to the rear side surface without being attached to the rear upper surface of the toilet body B. However, regardless of where the mounting shaft 3 is attached to the toilet body B, the support holes 21 and 21 of the device bodies 2 and 2 into which the hinge device H is inserted are provided with the toilet seat C and the toilet lid D. In order to rotate vertically, they are formed horizontally with their axes aligned.

As shown in FIGS. 2 and 5, the apparatus main body 2 is disposed on the upper surface of the toilet body B which is in a horizontal plane. The device main body 2 is formed with a mounting hole 22 penetrating vertically from the lower surface to the upper surface. A contact portion 33 of the mounting shaft 3 and a small-diameter shaft portion 32 are sequentially passed through the mounting hole 22 from its lower end opening, and the large-diameter shaft portion 31 is fitted. As a result, the apparatus main body 2 cannot be moved in the horizontal direction. In addition, the device bodies 2, 2 are prevented from rotating about the mounting shaft 3 by connecting the toilet seat C and the toilet lid D via the hinge devices H, H, respectively. The upper end surface of the device body 2 where the mounting holes 22 are open is a horizontal plane, and is located on the same plane as the upper end surface of the large-diameter shaft portion 31 or the upper end surface of the large-diameter shaft portion 31 It is located slightly above. Therefore, only the small-diameter shaft portion 32 and the contact portion 33 protrude upward from the upper surface of the apparatus main body 2. If the strength allows, the entire mounting shaft 3 except for the contact part 3 3 is the small diameter shaft part 3 2 It may be.

 As shown in FIGS. 3 to 5, an annular guide portion 23 is formed on the upper surface of the device main body 2. The guide portion 23 is formed with its axis (the rotation axis of the lock member 4) L directed upward and downward. Therefore, the axis L of the guide portion 23 is parallel to the axis of the mounting hole 22. The guide portion 23 is disposed such that its axis L is separated from the axis of the mounting hole 22 by a distance substantially equal to the radius of the mounting hole 22. Moreover, the inner diameter of the guide portion 23 is determined so that the mounting hole 22 is opened in a range surrounded by the guide portion 23. The upper surface (hereinafter simply referred to as the upper surface) 2 a of the device main body 2 surrounded by the guide portion 23 is a plane orthogonal to the axis L. Therefore, the upper surface 2a is parallel to the lower surface 33a of the contact portion 33 facing the upper surface 2a. The guide portion 23 has a notch portion 23 a extending in the circumferential direction. The notch portion 23a is located approximately in the forward and reverse circumferential directions of the guide portion 23 from the point where the line perpendicular to the axis L and the axis of the mounting shaft 3 intersects the guide portion 23 on the mounting shaft 3 side. It extends by an equal distance. In other words, the point where the line perpendicular to the axis L and the axis of the mounting shaft 3 intersects the guide portion 23 on the mounting shaft 3 side is the center in the circumferential direction of the notch portion 23a. The length of the notch portion 23 a in the circumferential direction of the guide portion 23 is set shorter than half the circumference of the guide portion 23.

 As shown in FIGS. 3 to 5, the lock member 4 has a disk portion 41. The disk portion 41 has a thickness substantially equal to the height of the guide portion 23, and an outer diameter substantially equal to the inner diameter of the guide portion 23. And it is rotatably inserted in the guide part 23. An operating rod 42 is provided on the outer peripheral surface of the disk portion 41. The operating rod 42 projects outside from the guide part 23 through the notch part 23a. The lock member 4 is rotated about the axis L of the guide portion 23 by holding the tip of the operating rod 42 protruding from the guide portion 23 and moving it in the circumferential direction of the guide portion 23 by hand. Can be.

The disk portion 41 is formed with a through hole 43 penetrating from the lower surface to the upper surface. The through hole 43 extends in the circumferential direction on the circumference around the axis L. At one end of the through hole 43, a large diameter hole 43a is formed. The large-diameter hole portion 43a has an inner diameter that is the same as or slightly larger than the outer diameter of the contact portion 33, so that the contact portion 33 can pass through. is there. The other end of the through hole 43 is a long hole 43 b extending in the circumferential direction around the axis L from the large diameter hole 43 a. The width of the long hole 43b (the distance between the inner peripheral side surface and the outer peripheral side surface of the long hole 43b) is almost the same as or slightly larger than the outer diameter of the small diameter shaft portion 3'2. Is set to Therefore, the small-diameter shaft portion 32 can move in the circumferential direction in the long hole portion 43b, but the contact portion 33 is not penetrable. A semicircular portion 4 c having a radius substantially equal to the radius of the small-diameter shaft portion 32 is formed at the tip of the long hole portion 43 (the end opposite to the large-diameter hole portion 43 a side). ing. The small-diameter shaft portion 32 abuts against the inner peripheral surface of the semicircular portion 43c, thereby preventing the rotation of the hook member 4 from the long hole portion 43b to the large diameter hole 43a side. Have been. The position of the lock member 4 at this time is the lock position. Conversely, when the contact portion 33 abuts on the inner peripheral surface of the large-diameter hole 43 a, the lock member 4 rotates from the large-diameter hole 43 a to the long hole 43 b. Are blocked. The position of the lock member 4 at this time, that is, the position of the lock member 4 when the contact portion 33 enters the large-diameter hole portion 43a is the release position.

 An accommodation recess 44 is formed on the upper surface of the disk portion 41. The accommodation recess 44 extends in the circumferential direction on the same circumference as the through hole 43. The width of the housing recess 44 (the distance between the outer circumferential side surface and the inner circumferential side surface of the housing recess 44) is set to be the same as the inner diameter of the large-diameter hole 43a. The length of the accommodation recess 44 in the circumferential direction is set to be the same as the length of the through hole 43. That is, semicircular portions 44 a and 44 b are formed at both ends of the housing concave portion 44. The center of one semicircular portion 44 a is aligned with the center of the large-diameter hole 43 a of the through hole 43. The center of the other semicircular portion 44 b is aligned with the center of the semicircular portion 43 c of the through hole 43. Accordingly, the circumferential length of the housing recess 44 (the circumferential length between the centers of the semicircular portions 44a and 44b) 周 the circumferential length of the through hole 43 (the large-diameter hole portion) Circumferential length between the centers of 43 a and semicircular portion 43 c).

As a result of the housing recess 44 being configured as described above, the semicircular portion 4 4a of the housing recess 44 is a semicircle opposite to the long hole 4 3b side of the large diameter hole 43a. This corresponds to the part, and constitutes a part of the large diameter hole 43a. Therefore, when the contact portion 3 3 of the mounting shaft 3 is inserted into the large-diameter hole portion 4 3 a of the through hole 4 3 from its lower end opening, the contact portion 33 becomes a semicircular portion 4 4 a of the accommodation concave portion 4 4. Into the side edge. As described above, the contact part 3 3 is a large-diameter hole When the lock member 4 is in the release position when the lock member 4 is at the release position when the lock member 4 is in the release position, the contact portion 3 3 of the mounting shaft 3 4 3 a) and the accommodation recess 44 can be removed.

 The semicircular portion 44a does not have a bottom surface because it forms a part of the large-diameter hole portion 43a, but the other portions of the storage M portion 404 except for the semicircular portion 44a are: It has a bottom surface 45 extending along the periphery of the through hole 43. Therefore, the lock member 4 is rotated in the direction from the semicircular portion 44b to the semicircular portion 44a, so that the mounting shaft 3 is moved from the large-diameter hole 43'a to the long hole 43b. When moved, the contact portion 33 faces the bottom surface 45. As a result, when the device body 2 is moved upward and the mounting shaft 3 is to be pulled out from the mounting hole 22, the contact portion 33 abuts against the bottom surface 45. As a result, the device main body 2 cannot escape from the mounting shaft 3.

 The bottom surface 45 is composed of an inclined surface 45a and a flat surface (press fixing surface) 45b. The inclined surface 45a extends from the contact point between the outer side surface of the housing recess 44 and the inner peripheral surface of the semicircular portion 44a along the outer side surface of the housing recess 44 to the semicircular portion 44b. It extends slightly to the front. The portion of the bottom surface 45 other than the inclined surface 45a is a flat surface 45b. Therefore, the flat surface 45a extends along the entire semicircular portion 43c and extends from the semicircular portion 43c to the inclined surface 45a; and extends along the fc hole 43b. I have. As a result, the length of the flat surface 45a is longer than the half arc corresponding to the semicircular portion 43c.

 The height from the upper surface 2 a of the apparatus body 2 to the inclined surface 45 a in the guide portion 23 is the lowest at one end of the large-diameter hole 43 a side of the accommodation recess 44, and the flat surface 4 from there.

It is gradually increasing up to 5 b. The height (the lowest height) at one end of the inclined surface 45a is set lower than the distance from the upper surface 2a to the lower surface 33a of the contact portion 33. Therefore, the lock member 4 is rotationally moved from the long hole 4 3 b side of the through hole 4 3 to the large diameter hole 4 3 a side with the contact portion 3 3 inserted in the large diameter hole 4 3 a. The small-diameter shaft portion 32 enters the long-hole portion 4 3b from the large-diameter hole portion 43a, and the contact portion 33 force-recessing recess 44 corresponds to the long-hole portion 43b. Get in. In this state, when the device main body 2 is moved upward and the mounting shaft 3 is to be pulled out from the mounting hole 21, the contact portion 33 abuts against the bottom surface 45 of the housing recess 23. Therefore, the equipment book Body 2 cannot be removed from toilet bowl B. .

 As shown in Figs. 5 and 6, the height from the top surface 2a to the flat surface 45b is

It is set to be the same as or slightly larger than the distance between 2a and the lower surface 33a of the contact portion 33. Therefore, when the flat surface 45 b is brought into contact with the lower surface of the contact portion 33, the lock member 4 is sandwiched and fixed between the upper surface 2 a of the device body 2 and the lower surface 33 a of the contact portion 33. In particular, when the lock member 4 is rotated to a position where the small-diameter shaft portion 32 abuts on the inner peripheral surface of the semicircular portion 4 3c of the through hole 43 (ie, a hook position), the lower surface of the contact portion 33 Since more than half of 33a (about 2/3 circle) abuts the flat surface 45b, the state where the contact portion 33 abuts the flat surface 45b is stably maintained. . Therefore, the lock member 4 is stably maintained at the lock position, and the device main body 2 is reliably prevented from falling out of the mounting shaft 3 upward. In addition, as a result of the locking member 4 being pinched and fixed by the lower surface 3 3 a of the contact portion 33 and the upper surface 2 a of the device body 2, the device body 2 is

It is pressed downward by the lock member 4 via the lock member 4, and is pressed and fixed to the upper surface of the toilet body B. The depth from the upper surface of the disk portion 41 of the lock member 4 to the flat surface 45 b is set to be greater than the thickness of the contact portion 33. Therefore, even when the lock member 4 is located at the lock position, the entire contact portion 33 enters into the housing recess 44. When attaching the toilet seat C and the toilet lid D to the toilet body B using the mounting device 1 having the above configuration, first, as shown in FIG. Attach seat C and toilet lid D. In this case, after the toilet seat C and the toilet lid D are rotatably connected to each other via the hinge devices H, H, the device bodies 2, 2 may be attached to the hinge devices H, H, respectively. After the hinge devices H, H are attached to 2, 2, the toilet seat C and the toilet lid D may be attached to each hinge device H, H.

Next, as shown in Fig. 3, the mounting shafts 3, 3 are inserted into the mounting holes 22, 22, of the device main bodies 2, 2, from the lower end opening. Thereafter, the locking member 4 is inserted into the guide portion 23 from above with the axis of the large-diameter hole portion 43 a aligned with the axis of the mounting hole 22. Then, the contact portion 33 of the mounting shaft 3 enters into the large-diameter hole portion 43a. Instead of this procedure, the lock member 4 may be inserted into the guide portion 23 in advance with the axis of the large-diameter hole portion 43 a aligned with the axis of the mounting hole 22. In other words, the lock member 4 may be previously positioned at the release position. In this case, the mounting shaft 3 is attached to the mounting hole 2 2 This is because the hole can be continuously inserted into the large-diameter hole 43a. When the lock member 4 is located at the release position, the operating rod 4 2 is moved in order to easily position the lock member 4 at the release position by aligning the axes of the mounting hole 22 and the large-diameter hole 43 a. However, it is desirable that the side of the notch 23 a be in contact with one side (the lower side in FIGS. 3 and 4) of the notch 23 a.

 Next, the hook member 4 is rotated in the direction from the semicircular portion 44b of the housing recess 44 to the semicircular portion 44a (the direction of the arrow in FIG. 3). Then, as shown in FIG. 4, the lock member 4 is rotated to a lock position where the small-diameter shaft portion 32 abuts against the inner peripheral surface of the semicircular portion 44b. Then, the lower surface 33a of the contact portion 33 presses and contacts the flat surface 45b. At this time, since the inclined surface 45a is formed in front of the flat surface 45b, the lower surface 44a smoothly presses and contacts the flat surface 45b. When the contact portion 33 presses against the flat surface 45b, the upward movement of the device body 2 is prevented by the contact portion 33 via the lock member 4, and the device body 2 is moved to the toilet body B. Is pressed and fixed on the upper surface. As a result, the toilet seat C and the toilet lid D are rotatably mounted on the toilet body B via the mounting devices 1 and 1 '. In addition, since the lock member 4 is sandwiched and fixed between the contact portion 33 and the apparatus main body 2, the lock member 4 is stably maintained at the lock position and does not move to the release position side. Therefore, the device body 2 is also stably fixed to the toilet body B.

 In order to remove the toilet seat C and the toilet lid D from the toilet body B, rotate the flap member 4 from the lock position shown in FIG. 4 to the release position shown in FIG. In this case, the position where the contact portion 33 abuts on the inner peripheral surface of the large-diameter hole portion 43a (the inner peripheral surface of the semicircular portion 44a) is the release position, so that the lock member 4 is easily released. Position. After that, the apparatus main body 2 and the hook member 4 are moved upward and pulled out from the mounting shaft 3. Of course, after the lock member 4 is pulled out from the mounting shaft 3, the device body 2 may be pulled out from the mounting shaft 3. When the device body 2 is pulled out from the mounting shaft 3, the toilet seat C and the toilet lid D are removed from the toilet body B together with the device body 2.

As described above, in the toilet mounting device 1, the device main body 2 can be attached to and detached from the toilet main body B only by rotating the opening member 4 by a little less than a half turn. It is not necessary to rotate the nut several times to several tens. Therefore, the device main body 2 can be easily attached to and detached from the toilet body B, and as a result, The toilet seat C and the toilet lid D can be easily attached to and removed from the toilet body B.

 In addition, the mounting device 1 has only three essential components, the device main body 2, the mounting shaft 3 and the lock member 4, and the number of components is significantly reduced as compared with the conventional mounting device using a lever. be able to. Therefore, manufacturing costs can be reduced.

 It should be noted that the present invention is not limited to the above-described embodiment, and can be appropriately changed within a scope not departing from the gist of the present invention.

 For example, in the above embodiment, the contact portion 33 is formed in an annular shape over the entire circumference of the small-diameter shaft portion 32, but the contact portion 33 contacts the entire flat surface 45b. Even in this state, the contact portion of the contact portion 33 with the flat surface 4 5 b is about 2/3 of the entire contact portion 33, so that the flat portion 4 is not formed without forming the contact portion 33 in an annular shape. The shape may be such that it has a length sufficient to make contact with 5b, for example, a circumferential length of about 2/3 circle. Further, in the above embodiment, the lock member 4 is rotationally displaced with respect to the mounting shaft 3 and the apparatus main body 2, but the lock member 4 is linearly displaced along the outer surface of the apparatus main body 2. You may. In that case, it is preferable to form a pair of guide portions extending in parallel with each other with the mounting shaft 3 interposed therebetween, instead of the annular guide portion 23. Of course, when the lock member 4 is linearly displaced, the through-hole 43 and the accommodation concave portion 44 are formed not in an arc but in a straight line. Industrial potential

 The toilet mounting device according to the present invention can be used as a mounting device for mounting a toilet seat and a valve lid to a toilet body.
