6A) with the damper (17) inserted, the ridge (19) on the rear surface of the damper (17) is formed in the groove (20) at the inner end of the insertion hole (18) of the bearing (16A). The damper (17) is prevented from rotating, and the shaft rod (21) of the damper (17) projects from the bearing (16A).

As shown in FIGS. 4 and 7, the other bearing (1
6B) has a through hole for a shaft pin (22) (shaft rod) having a head (23)
(24) is provided, and a cover (25) is attached to the bearing (16B). An opening (25A) is provided at the inner end of the cover (25), and a rib (25B) is provided inside the opening (25A) by folding back the wall. The outer edge is the outer wall
Blocked by (25C). Further, claws (26) are vertically provided on both edges of the cover (25), and the cover (25) is attached to the bearing.
The claws (26) of the cover (25) are attached to the bearing (16B).
(16B) Engages with locking grooves (27, 27) provided in the base (15) near both side edges. A pair of left and right mounting rods (32, 32) are extended from the lower surface of the base (15).

In the hinge mechanism (14), a bearing cover (28) is provided at the root end of the toilet seat (5) at the hinge portion on the pivoting body side, and a bearing cover (28) is provided at the root end of the toilet lid (6). Bearing bracket (29,
29) is inserted, and the bearing cover (28) and the bearing bracket (29) are provided with shaft holes (30, 31).

In order to assemble the hinge mechanism (14) , first, the mounting rods (32, 32) of the base (15) are provided with a pair of left and right mounting cylinders (33) provided at the rear end of the toilet body (2). , 33). Then, as shown in FIG. 8, the bearing cover (28) of the toilet seat (5)
Place the bearing brackets (29, 29) of the toilet lid (6) on the outer sides of both ends, and insert the shaft rod (21) of the damper (17) from one end into the shaft hole of one bearing bracket (29) of the toilet lid (6). (31) and the shaft seat (30) of the bearing cover (28) of the toilet seat (5). As shown in FIG. 9, the shaft rod (21) of the damper (17) has a circular cross section on both sides, and one shaft hole (30) of the bearing cover (28) of the toilet seat (5) is also formed. Corresponding to this, the shafts (21) of the damper (17) and the bearing cover (2
Mutual rotation is fixed with the shaft hole (30) of 8). In this state, the bearing bracket (29) of the toilet lid (6) and the bearing cover (28) of the toilet seat (5) are inserted between the bearings (16A, 16B) of the base (15). That is, the width W ₂ of the bearing bracket (29, 29) of the toilet lid (6)
The sum W ₂ + L ₁ of the main body length L ₁ of the damper (17) is
It is set to be approximately equal to or slightly smaller than the spacing W ₁ between the bearings (16A, 16B) of 5).

Next, the toilet seat (5) and the toilet lid (6) are displaced in the direction of arrow A in FIG. 8, and the damper (17) is moved as shown in FIG.
Is inserted into the insertion hole (18) in one of the bearings (16A), and the shaft pin (22) is inserted in the front and rear of the bearing through the through hole (24) of the other bearing (16B). It is inserted into the shaft hole (31) of the other bearing bracket (29) and the shaft hole (30) of the bearing cover (28) of the toilet seat (5). In this state, the other bearing bracket (29) of the toilet lid (6)
The gap W ₃ between the bearing (16B) and the base (15) is the damper (17)
Is approximately equal to the body length L ₁ .

Finally, as shown in FIG. 11, the cover (25) is attached to the bearing (16B) of the base (15), and the claws (26) of the cover (25) are attached.
Is engaged with and fixed to the locking groove (27) of the base (15). In this state, the bearing bracket (29) and the other bearing (1) of the base (15)
6B) and the gap width W ₃ is filled with the cover (25),
Further, as shown in FIG. 12, the outer wall (25C) of the cover (25) is in close contact with the head (23) of the shaft pin (22) penetrating the bearing (16B). ) Are fixed to prevent the ribs from coming off, and as shown in FIG. 13, the width W ₄ of the rib (25B) inside the opening (25A) of the cover (25) is set to be substantially equal to the gap width W ₃ . The inner end of the rib (25B) abuts the outer end of the bearing (16B). The inner end of the cover (25) contacts the other bearing bracket (29) of the toilet lid (6) to prevent the toilet seat (5) and the toilet lid (6) from being displaced in the direction of arrow B in FIG. Thereby the toilet seat
One shaft hole (30) of the bearing cover (28) of (5) and the toilet lid
(6) The shaft rod (21) of the damper (17) is pulled out from the shaft hole (31) of the one bearing bracket (29), or the damper (1
7) is prevented from being pulled out from the insertion hole (18) of the one bearing (16A) of the base (15), but when an external force in the direction of arrow B is applied to the cover (25), The rib (25) of the cover (25)
Since the inner end of (B) is in contact with the outer end of the bearing (16B) as described above, stress is concentrated on the claw (26) of the cover (25) and the claw (26) is broken. Is prevented.

In the present invention, when the hinge mechanism is assembled, the damper (17) is supported on the pivot body side (toilet seat lid side).
On the foundation side (one bearing (16A) side of the base (15)), the damper (1
7) may be supported. In this case, the sum L ₂ + W ₂ of the length L ₂ of the shaft rod (21) of the damper (17) projecting from the bearing (16A) and the length W ₂ of the hinge portion of the pivot body is L ₂ + W _2.
It is set to be equal to or slightly smaller than the interval W ₁ of (16A, 16B). Further, in the present invention, since one of the pivot body side and the base bearing are connected by the shaft of the damper, when the toilet seat (5) is closed, the rotation of the toilet seat (5) is slowed down, and it is necessary to put the hand to the end. Absent. However, the damper is not essential, and a shaft pin may be used in place of the damper, and a shaft hole is provided on one side of the pivot body, and a shaft rod extended from the bearing side of the foundation is inserted into the shaft hole. Alternatively, the shaft rod extending from the pivot body side may be inserted into the shaft hole of the base bearing.

[0015]

According to the present invention, the shaft rod at one end of the hinge portion of the pivot member is inserted into the shaft hole of one of the bearings of the base, or the shaft rod at the one end of the hinge portion of the pivot member is attached to the base. After inserting the shaft rod of one bearing, or after passing the shaft pin (shaft rod) into the shaft hole of one end of the hinge portion of the pivot body and the shaft hole of one bearing, the other of the foundation The bearing is covered with a cover, and the cover fills the space between the bearing and one end of the hinge portion of the pivot body and prevents the shaft pin from coming off. Therefore, the assembly of the hinge mechanism is extremely simple and easy. I can do it.
