Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a shock absorbing device for a toilet seat in a toilet bowl, and is applicable not only to an opening/closing toilet seat of a general Western-style toilet bowl, but also to a toilet seat in a human body private parts cleaning device, and a stand-alone type. It is useful for heating toilet seats, etc.

(Prior Art) As this type of device, techniques described in US Pat. No. 3,345,650 and Japanese Patent Application Laid-Open No. 58-200720 are known. As shown in FIGS. 7 and 8, generally when the toilet bowl is used at 1°, the toilet seat M3'a is raised and used. Therefore, when lowering these items after using the toilet, there was a risk that the children would become separated and fall onto the top surface of the toilet bowl. In any of the above conventional techniques, a transparent surface means for mitigating the impact is provided by combining a cylinder and a piston (not shown),
Noise caused by impact, toilet seat 1 toilet lid foot 3°b,
Measures were taken to prevent damage to the hinge 4'.

(Problems to be Solved by the Invention) However, the configuration according to the prior art requires a large space in terms of shape and dimensions, and is F in terms of manufacturing and cost.
One point was observed.

In addition, in terms of operation, a buffering force acts over the entire fall angle range from the maximum raised position of the toilet seat to the point of fall, and unnecessary resistance was observed when the toilet seat was pulled up. These factors are considered to be factors that have an unfavorable effect on the smooth operation of opening and closing the toilet seat.

The present invention aims to achieve the desired purpose by using a device having an hour wheel configuration without the above-mentioned conventional defects.

[Structure of the invention]

(Means for Solving the Problems) In order to solve the above problems, the present invention employs the following means. That is, (1) The buffering force acting on the toilet seat is not applied over the entire angular range from the maximum raised state to the falling point, but only within a predetermined range immediately before the falling point.

(2) When the toilet seat is opened (raised), the operating resistance is removed.

(Function) A buffering force acts on the toilet seat in a short range only within a predetermined range of angles up to just before the point of fall, and there is no resistance load when it is pulled up.

(Example) Hereinafter, an example of the apparatus of the present invention will be described based on FIGS. 1 to 5.

In the figure, 1 is a toilet bowl (upper surface part), 2 is an outer case, and 3 is a toilet seat, which is integrally supported with a lever 5 by a hinge shaft 4 at a suitable position behind the toilet bowl 1 so as to be rotatable in the vertical direction. The toilet seat 3 is always seated and stationary (closed position) on the top surface of the toilet bowl 1 as shown in the first figure. Numeral 6 is a cylindrical body which is fixed to the base plate 7 with screws 8, and the cylinder chamber of the cylindrical body 6 is fixed to the base plate 7 with screws 8. A piston 9 is biased in one direction by a spring 10 and fitted in the hole a so as to be slidable in the axial direction. Thus, 9a is a shaft portion from which the piston 9 extends. 1
Reference numeral 1 denotes a lid body that airtightly closes the opening portion 11a of the cylinder chamber 63 of the cylinder body 6, which slidably guides the piston shaft portion 9a and hermetically seals the cough shaft portion 9. .

12 is a return hole provided in the piston 9, and 13 is a check valve that unidirectionally closes the return hole 12.

Note that 14 indicates a fluid sealed in the cylinder chamber a.

Next, the operation of this embodiment will be described.

In its normal state, the toilet seat 3 in FIG. 1 is seated on the top surface of the toilet bowl l due to its own weight. Under this state, the piston 9 is pushed down against the spring 10 through the piston shaft 9a by the lever 5 which is movable integrally with the toilet seat 3. When the piston 9 descends, the fluid 14 in the lower chamber of the cylinder chamber 6a, which is removed thereby, moves through the fitting gap to the upper chamber as shown by the arrow.

When the toilet seat 3 is pulled up from the state shown in the first figure to the state shown in the second figure, the engagement between the lever 5 and the piston shaft portion 9a is released. Therefore, the piston 9 rises due to the tension of the spring 10, and the fluid in the upper chamber of the cylinder chamber 6a moves toward the lower chamber through the return hole 12, as shown by the arrow, and moves the check valve 13. Therefore, when the toilet seat is lifted up, there is no operational resistance that would be a hindrance, and the toilet seat can be smoothly brought into the open state shown in the third figure.

Next, the process of changing the toilet seat 3 from the open state a (shown in the third figure) to the closed state (shown in M1) will be described.

That is, when the toilet seat 3 rotates and the lever 5 reaches the position shown in FIGS. 3 to 4, the lever 5 comes into contact with the piston shaft portion 9a.

This rotation angle is θ shown in FIG. 3, and the operation of the toilet seat 3 within this angle range is quick and easy. Then, the piston 9 moves to the downward stroke, but from this point on, fluid pressure is generated in the lower chamber of the cylinder chamber 6a, which closes the check valve 13 and the fluid flows to the upper chamber through the fitting gap.
Resistance occurs when the piston 9 moves downward. Therefore, the above-mentioned resistance acts on the closing operation of the valve seat 3 within the downward range of the piston 9, that is, within the angle range of the rotation angle θ2 of the lever 5, and thereby the impact is alleviated.

Further, FIG. 5 shows the check valve in this embodiment as seen from the lower side of the piston, and FIG. 6 shows another embodiment of the piston 9'' having an orifice indicated by the reference numeral 15, and a return hole in the piston. This is a dedicated orifice hole instead of a fitting gap.

〔Effect of the invention〕

In the present invention, a lever is provided on the shaft that rotatably supports the valve seat,
This was brought into contact with the driving part of the dashpot from an appropriate angle before the vehicle fell into the seat, to cushion the impact. Therefore, the following remarkable effects can be expected. That is, (1) Since the buffering force acts only on the specified range immediately before the fall, the closing action is performed smoothly and quickly.

(2) There is no operating resistance when the toilet seat is pulled up (opened) (easy to handle).

(3) Due to its simple configuration, it is easy to maintain functions over a long period of time without the risk of failure.

(4) Impact during the closing operation is eliminated, and damage to the toilet seat itself and the internal storage device can be prevented.

(5) The closing action is visually and sensibly superior, leading to improved product value.

(6) The entire shock absorbing device can be housed in the outer case that pivotally supports the toilet seat, and no mechanical components protrude, so the appearance can be improved.
