JPH064799Y2 - Pivoting device for the body of the toilet - Google Patents

Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a device for pivotally supporting a toilet body such as a toilet seat or a toilet lid with respect to the toilet bowl, and in particular, the toilet seat or the toilet bowl is a toilet bowl. The present invention relates to a pivotal support device for a torso of a toilet, which is configured to gently swing down.

[Prior Art] When a toilet seat or a toilet lid that is in an upright state with respect to a toilet bowl is rotated to the front side of the toilet bowl and the hand is released, the toilet seat suddenly pivots and descends due to its own weight, and falls down on the upper surface of the toilet bowl.

It is known to use a rotary oil damper in order to prevent the impact sound and the damage of the equipment and the equipment due to the impact. Further, Japanese Utility Model Application Laid-Open No. 62-95698 discloses that a spring for urging the toilet seat / toilet lid in the upright direction is provided.

[Problems to be solved by the invention] When an oil damper is used, the force is reduced not only when rotating in the fall direction but also when rotating in the upright direction. It takes force and cannot lift quickly. In addition, the oil damper requires many precise components and is expensive.

When biasing the toilet seat / toilet lid in the upright direction with a spring,
An upward force is always applied to the toilet seat / toilet lid in the prone state. However, since the toilet seat and the toilet lid are usually synthetic resin molded products, stress cracking may occur if stress is continuously applied, and durability is poor.

[Means for Solving the Problems] The pivoting device for the elephant-elevator for a toilet according to claim 1 of the present invention is a device for pivotally attaching the base end of the elephant-elevator to the upper surface of the toilet bowl on the back side of the bowl. It is provided with the following fixed cylinder, rotary cylinder, coil spring screw member, and elastic member.

The fixed cylinder is attached to the upper surface on the back side of the bowl portion with the cylinder axis direction in the toilet width direction.

The rotary cylinder has an outer peripheral surface slidably inserted into one end of the fixed cylinder so as to be slidable with the inner peripheral surface of the fixed cylinder, has a slit extending in the cylinder axial direction, and the inner hole has a tip in the insertion direction. It has a tapered shape with a smaller diameter toward the side.

The coil spring is inserted into the inner hole of the rotary cylinder, the front end side in the insertion direction is in close contact with the inner peripheral surface of the inner hole, and the rear end part in the insertion direction is locked to the base end part of the elevation body. To be done. And
When the elevation body is rotated in the fall direction, the diameter is increased, and the non-tip portion in the insertion direction presses the inner peripheral surface of the inner hole.

The screw member is screwed into the other end of the fixed cylinder.

The elastic member is interposed between the screw member and the rotary cylinder so that the rotary cylinder can be pressed.

In the pivot support device for a toilet bowl elevation body according to claim (2), in the pivot support device for a toilet bowl elevation body according to claim (1), the inner hole of the rotary cylinder has substantially the same diameter, and the coil spring has a truncated cone shape. . This coil spring is installed such that the tip end side in the insertion direction into the inner hole is in close contact with the inner peripheral surface of the inner hole, and the rear end side in the insertion direction has a small diameter.

According to the pivot support device for the toilet body of the present invention, a sliding plate is interposed between the elastic member and the rotary cylinder.

[Operation] In the pivot support device for the toilet body of the toilet according to claims (1) and (2), when the body in the upright state is rotated in the fall direction,
The coil spring is twisted in the loosening direction, and the coil spring is expanded so as to bulge. The coil spring thus expanded in diameter contacts the inner peripheral surface of the inner hole and tries to expand the diameter of the rotary cylinder.
Since the rotary cylinder is provided with a slit in the cylinder axial direction, the rotary cylinder tries to expand the diameter by the expanding force of the coil spring, and thereby the outer peripheral surface of the rotary cylinder is strongly pressed against the inner peripheral surface of the fixed cylinder. . As a result, the frictional force between the outer peripheral surface of the rotary cylinder and the inner peripheral surface of the fixed cylinder becomes large, and the elevation body slowly turns down and falls down gently.

When the supine body falls down, the coil spring strongly presses the inner hole of the rotating cylinder as the falling speed of the supine body increases, and the frictional force between the rotating cylinder and the fixed cylinder increases, so that the supine body falls down. The force that suppresses the speed increases. That is, the inner hole is a tapered hole as in claim (1), or the coil spring is frustoconical as in claim (2), and the greater the twist displacement of the coil spring, the more A larger portion contacts the inner peripheral surface of the inner hole, and the pressing force in the radial direction applied to the rotary cylinder becomes strong. Therefore, the supine body always descends at a properly controlled and slow speed and gently falls on the toilet bowl.

When the lie-down body in the lying state is erected, the coil spring is twisted in the direction of its withdrawal, and the coil spring tries to reduce its diameter. Therefore, the rotary cylinder is not pressed by the coil spring in the radial direction, and the rotary cylinder and the fixed cylinder slide with a weak frictional force. Therefore, when the lying-down body is rotated to the upright state, the lying body can be rotated with a light operating force.

When the screw member is advanced, the elastic member is pressed strongly against the rotary cylinder, and the frictional force between the rotary cylinder and the elastic member (or between the elastic member and the screw member) increases. Therefore, the sliding resistance of the rotating cylinder during rotation increases. Conversely, when the screw member is retracted, this sliding resistance becomes smaller. In this way, by adjusting the degree of tightening of the screw member, it becomes possible to adjust the frictional resistance against the rotation of the elevation body during rotation.

In the pivot support device for the toilet body of the third aspect of the present invention, sliding between the elastic member and the rotary cylinder can be made smooth.

Reference numeral 6 denotes a pedestal portion, which has a bolt 8 penetrating through a bolt hole 7 of the toilet bowl 1, and a pivot support device 5 is fixed to the toilet bowl 1 by tightening a nut 9 into the bolt 8. A fixed cylinder 11 is integrally provided on the pedestal portion 6, and the pivot support device 5 is attached to the toilet 1 such that the cylinder axis direction of the fixed cylinder 11 is the width direction of the toilet 1.

The rotary cylinder 12 is inserted into the fixed cylinder 11 from one end side,
The screw member 13 is inserted from the other end side. Rotating cylinder 12
Has a slit 12a extending in the cylinder axis direction. In this embodiment, the rotary cylinder 12 has a shape in which the front end side in the insertion direction is sealed and the rear end side is opened, and the slit 12a is extended from the rear end side to reach the center of the cylinder front end surface 12b. There is.

The inner hole 12c of the rotary cylinder 12 is a tapered hole whose diameter decreases toward the front end side in the insertion direction. The coil spring 14 is inserted into the inner hole 12c, and the tip of the coil spring 14 in the insertion direction is tightly fitted to the inner peripheral surface of the tip of the inner hole 12c in the insertion direction so that the coil spring 14 slides in the circumferential direction. It is constructed so as not to rotate dynamically.

The coil spring 14 has a cylindrical shape of equal diameter, and the coil spring 1
4, when the external force is not applied to the coil 4, the inner peripheral surface of the rotary cylinder 12 and the coil spring 14 are moved toward the rear end in the insertion direction.
The gap between and becomes large.

The toilet seat 3 is provided with a side plate portion 3a and a stopper portion 3b, the side plate portion 3a is provided with an opening 3c into which the fixed cylinder 11 is inserted, and the toilet seat 3 is placed in a vertical direction with the fixed cylinder 11 as a rotation center. It is supposed to be rotatable. The stopper portion 3b extends along one end surface of the fixed cylinder 11, and a rear end portion of the coil spring 14 in the insertion direction is engaged with a groove 3d provided in the stopper portion 3b.

A female screw portion 11a is provided on the other end side (right end side in the drawing) of the fixed cylinder 11, and the screw member 13 is screwed into the female screw portion 11a. The tip of the screw member 13 is a piston portion 13a. Further, a driver insertion groove 13b is provided at the rear end of the screw member 13. A spring 16 is inserted in the fixed cylinder 11, and the rotary cylinder 1
2 and the screw member 13 are urged in a direction away from each other.

Sliding plates 17 and 18 are interposed between the spring 16 and the piston portion 13a, and between the spring 16 and the barrel tip surface 12b, respectively.

The operation of the pivot device 5 thus constructed will be described below.

When the toilet seat 3 in the upright state is rotated in the fall direction, the coil spring 14 is twisted in the loosening direction, and the coil spring 14 expands in diameter so as to bulge. The coil spring 14 thus expanded in diameter contacts the inner peripheral surface of the inner hole 12c and tries to expand the diameter of the rotary cylinder 12.

Since the rotary cylinder 12 is provided with the slit 12a in the cylinder axis direction, the rotary cylinder 1 is expanded by the expanding force of the coil spring 14.
2 tries to expand the diameter, whereby the outer peripheral surface of the rotary cylinder 12 is strongly pressed against the inner peripheral surface of the fixed cylinder 11. As a result,
The frictional force between the outer peripheral surface of the rotary cylinder 12 and the inner peripheral surface of the fixed cylinder 11 increases, and the elevation body slowly rotates and descends, and falls gently. When the fall speed of the toilet seat 3 is low, the difference between the rotational angular speed of the toilet seat 3 and the rotational angular speed of the rotary cylinder 12 is small, and the displacement of the coil spring 14 in the twisting direction is small. For this reason, the coil spring 14 does not expand so much, and the coil spring 14 does not expand.
The compression force given to 2 is not so great. However, when the falling speed of the toilet seat 3 increases, the difference between the rotational angular speed of the toilet seat 3 and the rotational angular speed of the rotary cylinder 12 increases, and the displacement of the coil spring 12 in the twisting direction increases. As a result, the coil spring 14 is greatly expanded in diameter, and the rear end side portion in the insertion direction also presses the inner peripheral surface of the inner hole 12c, so that the outer peripheral surface of the rotating cylinder 12 covers the inner peripheral surface of the fixed cylinder 11 over a wide range. You will be able to press strongly. Therefore, a strong braking action is applied to the toilet seat 3, and the toilet seat 3 descends at a slow speed,
Gently fall down on the toilet bowl 2.

When the toilet seat 3 in the lying state is to be erected, the coil spring 14 is twisted in the direction in which it is narrowed, and the coil spring 14 tries to reduce its diameter. For this reason, the rotary cylinder 12 has a coil spring 14
The rotary cylinder 12 is not pressed by the radial expansion direction by the
And the fixed cylinder 11 slide with a weak frictional force. Therefore, when the toilet seat 3 in the lying state is rotated to the upright state, it can be rotated with a light operating force.

In this embodiment, when the screw member 13 is rotated and screwed forward, the spring 16 as an elastic member is compressed and the sliding plate 17 is pressed against the barrel tip surface 12b of the rotary barrel 12. As a result, the frictional force between the rotary cylinder 12 and the sliding plate 17 increases, and the frictional force when the toilet seat 3 is rotated in the vertical direction increases.

Conversely, when the screw member is retracted, the spring 16 expands,
The above frictional force is reduced. Therefore, by adjusting the degree of tightening of the screw member 13, the frictional resistance when the toilet seat 3 is rotated in the vertical direction can be adjusted.

The spring 16 may rotate together with the rotation of the rotary cylinder 12, in which case the sliding plate 18 and the spring 16 or the piston portion 13a slide.

FIG. 5 shows another embodiment of the invention, which is a rotary cylinder 1
The second inner hole 12c has a uniform diameter. The coil spring 14 has a truncated cone shape whose diameter becomes larger toward the tip end side in the insertion direction, and the tip end is tightly fitted to the inner peripheral surface of the inner diameter 12c to prevent sliding in the circumferential direction. Other configurations are similar to those of the above-described embodiment, and the same reference numerals indicate the same parts.

Also in the embodiment of FIG. 5, when the toilet seat 3 is rotated in the fall direction, the coil spring 14 expands in diameter, the frictional force between the rotating cylinder 12 and the solid cylinder 11 increases, and the toilet seat 3 rotates slowly. Then
Gently lay on the toilet bowl 2. Further, when the toilet seat 3 is rotated in the upright direction, the coil spring 14 is recessed, the frictional force between the rotary cylinder 12 and the fixed cylinder 11 is reduced, and the toilet seat 3 can be lifted with a light operating force. .

Although the above embodiment is used for pivoting the toilet seat, the toilet lid can also be pivoted in the same manner. In this case, 1
It is possible to provide two fixed cylinders 11 on each pedestal portion 6, one fixed cylinder 11 to pivotally support the toilet seat, and the other fixed cylinder 11 to pivotally support the toilet lid.

In the present invention, the rotary cylinder 12 and the fixed cylinder 11 slide with a proper frictional force, and it is preferable that the rotary cylinder 12 is made of, for example, an oil-impregnated synthetic resin. It can be used as a material.

[Effects] As described above, in the pivotal support device for the elephant-elevator of the present invention, when the elephant-elevator such as the toilet seat or the toilet lid is rotated in the fall direction, the coil spring expands and is fixed to the rotary cylinder. The frictional force with the cylinder increases, and the body is slowly rotated, and it gently falls on the toilet bowl. When the elevation body is rotated in the upright direction, the coil spring is narrowed, the frictional force between the rotary cylinder and the fixed cylinder is reduced, and the elevation body can be lifted with a light operating force.

By adjusting the degree of tightening of the screw member, it is possible to adjust the frictional resistance when the elevation body rotates in the vertical direction.

The pivot device of the present invention has a small number of parts, is easy to assemble, and is inexpensive. Further, there is no place where external force is always applied, and even if it is made of synthetic resin, stress cracking does not occur.
