Bidet Hinge Device {DEVICE OF HINGE FOR BIDET}

The present invention relates to a hinge device for a bidet, and more particularly, by reducing the impact force accelerated by its own weight during rotation rotation of the toilet seat and the toilet seat cover coupled to open and close from the bidet body by the hinge according to the impact The present invention relates to a bidet hinge device that prevents the occurrence of noise and damage and automatically opens and closes a certain section.

In general, the bidet is a sanitary appliance that is installed on the upper side of the toilet seat and used to maintain the cleanliness of the user after using the toilet seat.

Hereinafter, a bidet conventionally used is a bidet body fixed to an upper toilet seat and controlled by a controller and the controller on one side, and having a spray nozzle for spraying water, and hinged to the bidet body so as to be pivotally coupled to the toilet seat. Consists of a toilet seat and a toilet seat cover to open and close the upper surface.

In order for a user to use the toilet seat, the toilet seat and the toilet seat cover are opened or closed manually or configured to be automatically opened and closed by an additional hydraulic switch.

However, when the toilet seat and the toilet seat cover is manually opened and closed by the user, the speed of rotation opening and closing by the own weight is accelerated at a predetermined angle or more, and there is a problem in that impact noise occurs or damage occurs when used for a long time.

In addition, in order to prevent the impact noise and damage caused by the shock accelerated by its own weight when opening and closing the toilet seat and the toilet seat cover, the inconvenience that the user must hold the toilet seat and the toilet seat cover to open and close completely. there was.

In addition, in the case of a bidet switchgear that induces deceleration using fluid resistance, if the deceleration force is generated to the extent that there is no end impact, the overall closing speed is excessively slowed, or conversely, if the closing speed is increased, Not only do not remove the shock, but also if the user does not move the toilet seat completely in the open position, it is closed again, or if the room temperature changes, the viscosity of the working fluid is followed and the descending speed is rapidly changed accordingly.

The present invention was devised to improve the above problems, and when closing the toilet seat from the bidet body, the closed end shock and impact noise generated by accelerating the toilet seat descending speed by the self-weight moment which increases rapidly from a certain downward angle point The purpose of the present invention is to implement the function of equalizing the descent speed between the closing angles of the bulbs while being completely removed.

In addition, when raising the toilet seat is lifted with less force, and once placed the toilet seat is aimed to never descend unless the external force is applied.

In addition, as in the case of a bidet hinge device using a fluid resistance, if the room temperature changes, it is more convenient to always maintain a constant descent speed even if there is a temperature change without the problem that the descent speed is changed by the viscosity change of the internal working fluid. The goal is to achieve high-end functional functionality.

As shown in FIG. 1, the bidet 1 is coupled to be seated on the upper side of the toilet seat and is controlled to spray water by the control box 11 and the control box 11 provided at one side. ) Is equipped with a bidet body 10, the bidet body 10 and the hinge 40 is coupled to the toilet seat 20 and the toilet seat cover 30 is coupled to the upper side of the toilet seat to be opened and closed.

Hereinafter, the hinge device used for the toilet seat 20 and the toilet seat cover 30 can be used both the hinge device for the bidet of the present invention and to describe only the toilet seat 20 as an example to avoid duplicate description Shall be.

As shown in FIGS. 2 to 6, the hinge 40 is fixed to the bidet body 10 and has a hollow housing 50 open at one side to have an inner receiving space, and the housing 50. Linear motion cam pressure spring (60) accommodated in the inside and the linear motion cam (70) accommodated in a linear transfer within the housing (50) to be elastically pressurized by the linear motion cam pressure spring (60). And one end is inserted into and coupled to the housing 50 open end to engage the linear motion cam 70 and frictionally rotate with the inner circumferential surface of the housing 50, and the other end to rotate together with the toilet seat 20. Rotating cam 80 to be coupled, the rotation cam pressing spring 90 to elastically press the rotation cam 80, the housing 50, the linear motion cam pressure spring 60, linear motion cam 70, The rotating cam 80 and the rotating cam pressure spring 90 pass through the same axis. W consists of a fastening member 100 for securing fastening.

The housing 50 has a plurality of fixing protrusions 53 protruding on the outer circumferential surface for fastening to the bidet body 10 and hypothetically extended along the outer circumference of the housing 50 from the fixing protrusion 53. The reinforcement protrusion 54 is provided.

In addition, the inner receiving space of the housing 50 is the linear motion cam 70 is elastically pressurized by the linear motion cam pressure spring 60 so that the linear motion to be seated to accommodate only linear movement in the axial direction The cam receiving portion 51 and the rotating cam inserting portion 52 which is formed to have a predetermined inclination angle from the linear motion cam receiving portion 51 so as to extend the cross section toward the open end side.

The linear motion cam (70) is stepped to have a circular cross section from the seating portion (71) of the rectangular cross-section seated and fixed to the linear motion cam receiving portion (51) of the housing (50) A protrusion 75 is formed to protrude and is formed with a pressure inclined surface 76 so that different elastic repulsive forces act along the circumference of the end.

The seating portion 71 forms a spring receiving groove 72 so as to receive one end of the linear motion cam pressure spring 60 on one side so as to more stably transmit the elastic repulsive force, and the length of the hinge. It is possible to form a smaller, the assembly guide groove 73 is formed on the outer peripheral surface so that the assembly process of the linear motion cam 70 is made easier and faster.

In addition, the assembling guide groove 73 is more preferably formed to be grooved along one side edge portion as the seating portion 71 is formed to have a rectangular cross-section.

The pressing inclined surface 76 formed along the end circumference of the protrusion 75 has a stop section between 0 ° and 20 ° to maintain a stop state at a downward inflection point B of the 20 ° portion in which the toilet seat 20 is opened. (AB) is formed to be inclined downward at a predetermined angle, and then pressurization section BC is formed to be inclined upwardly between 20 ° and 60 ° so that closing starts only after a certain force is applied, and an inflection point C formed at a 60 ° part is formed. Acceleration section (CD) between 60 ° ~ 80 ° is formed to be inclined downward so as to be accelerated by the linear motion cam pressure spring (60) to facilitate the closing automatically, and then by the opening speed accelerated by its own weight The damping section DE is formed to be inclined upwardly between 80 ° and 140 ° to offset the generated impact force.

In addition, the remaining 140 ° to 180 ° section is an unused section (EG), and particularly, in the 140 ° to 160 ° section (EF), the forming protrusion 82 of the rotation cam 80 is along the damping section DE. It is preferable that the damping section DE is formed to have an inclination angle so as not to be caught during rotation.

In the above description, the angular angle defined in each section is not an absolute element constituting the present invention, but is an angle that can be changed as intended by the functional designer of the entire bidet device.

In addition, the inclination angles of the stop section AB, the pressurization section BC, the acceleration section CD, and the damping section DE of the pressure inclined surface 76 are the weight of the toilet seat 20 and the linear motion cam pressure spring. It is relatively determined by the elastic repulsive force (RF) of 60 and the magnitude of the frictional force (FF) generated by the rotational cam pressing spring 90, in order to allow the toilet seat 20 to rotate and open more smoothly. Each section of the inclined surface 76 is more preferably made of a multi-order function.

The rotation cam 80 is inserted into the engaging portion 81 to be rotated and friction with the inner surface of the open end side rotation cam insertion portion 52 of the housing 50, and extends stepped from the insertion portion 81 It is hypothesized to be made of a fastening portion 85 coupled to interlock when the toilet seat 20 is opened and closed.

The insertion part 81 accommodates a part of the protrusion 75 of the linear motion cam 70 therein, and rotates along the pressure inclined surface 76 of the linear motion cam 70, according to the shape of each section. The movement cam 70 is transferred to press the linear movement cam pressure spring 60 to accelerate the rotation speed in a predetermined section during rotational opening and closing of the toilet seat by the elastic repulsion force of different sizes generated at this time, or the rotation speed To reduce the pressure and to reduce the impact force at the closed end of the toilet seat, a mating projection 82 is formed on the inner surface facing the pressure inclined surface 76 and the pressure inclined surface 76, the outer peripheral surface of the housing 50 A friction inclined surface 83 having a predetermined inclination angle is formed in friction contact with the inner circumferential surface of the rotation cam inserting portion 52.

The fastening part 85 has a step portion 86 formed on an outer circumferential surface of the fastening unit 85 to be interlocked with the toilet seat 20, and has a spring receiving groove 87 to accommodate the rotation cam pressure spring 90 therein. ) Is formed.

The rotating cam pressure spring 90 is coupled to be received in the spring receiving groove 87 of the rotating cam 80 so that the friction inclined surface 83 of the rotating cam 80 is inserted into the rotating cam of the housing 50. (52) By pressing to rotate the friction with the inner circumferential surface, the toilet seat 20 is to reduce the rotational speed in all sections during the rotation opening and closing by the generated frictional force to reduce the impact force.

The friction inclined surface 83 has at least one oil groove 84 for filling lubricating oil to prevent abrasion during friction with the inner circumferential surface of the housing 50 due to the elastic repulsive force of the rotational cam pressing spring 90. More preferably, eight oil grooves 84 are formed at equal intervals along the circumference of the friction inclined surface 83.

The oil groove 84 is filled therein without a separate leak prevention means such as an "O" ring, and both ends of the groove are inserted into the rotating cam by the rotating cam pressure spring 90 so that the lubricant does not leak. (52) It is formed so that it may be located in the part compressed with the inner peripheral surface.

The lubricating oil preferably uses grease having a relatively high viscosity to prevent friction of the friction inclined surface 83 as well as to generate a frictional force for reducing the impact force.

The fastening member 100 penetrates through the housing 50, the linear motion cam pressure spring 60, the linear motion cam 70, the rotation cam 80, and the rotation cam pressure spring 90 to be positioned on the same axis line. The fixed bolt 101 and the linear cam (70) and the rotary cam (80) located on the same axis line by the fixing bolt 101 are the linear cam cam pressure spring (60) and the cam cam pressure spring ( 90 is composed of a fixing nut 102 is fastened to be pressed by the pressure, and the self-locking nut 103 is further fastened to prevent the fixing nut 102 from being released from the fixing bolt 101.

It is preferable that the nut mounting groove is recessed on one side of the housing 50 to fasten the fixing nut 102 to the fixing bolt 101 to be seated on one side of the housing 50.

In addition, it is more preferable to fasten the washers 104, 105, 106 and 107 at both ends so that the linear cam cam pressure spring 60 and the rotary cam press spring 90 generate a normal elastic force.

Referring to the operation and effects of the bidet hinge device of the present invention having such a configuration in detail as follows.

First, when the assembly process and the operation state of the hinge device for the bidet of the present invention is described schematically, the housing 50 of the hinge 40 on one side of the bidet body 10 is coupled so that the toilet seat 20 is rotated and opened. ), And the fastening part 85 of the rotation cam 80 is assembled to be inserted and fixed at one side rotation center of the toilet seat 20, the linear motion cam 70 and the rotation cam of the hinge 40. Rotation of the friction inclined surface 83 of the rotating cam 80 and the housing 50 by the elastic repulsive force RF of the linear motion cam pressing spring 60 generated by the interaction of the 80 and the rotating cam pressing spring The toilet seat 20 is accelerated in a predetermined section by the friction force FF generated between the inner circumferential surfaces of the cam inserting portion 52 and rotated to be automatically opened or closed, or buffers the impact force generated by the rotational force caused by its own weight. Prevent noise and damage caused by

7 to 11, the process in which the toilet seat 20 is lowered to the upper side of the toilet seat is divided into sections according to the shape of the pressing inclined surface 76 of the linear motion cam 70. I will explain.

As shown in FIG. 7, the friction inclined surface 83 and the housing of the rotating cam 80 are rotated by the rotating cam pressure spring 90 in the entire section where the toilet seat is rotated from the B point to the E point so as to be located on the upper toilet seat. The friction force (FF) generated between the inner circumferential surface of the rotating cam inserting portion (52) of 50) acts uniformly, and the linear motion generated by the interaction of the linear cam (70) and the rotating cam (80) in each section. The elastic repulsive force (RF) of the cam pressing spring 60 acts linearly in accordance with the shape of the pressing inclined surface.

As shown in FIG. 8, the stop section AB is a section in which the toilet seat 20 is stopped after the toilet seat 20 is completely lifted from the upper surface of the toilet seat, and interlocks with the toilet seat 20. The matching protrusion 82 of is in the state located at the point B which is a downward inflection point.

The point B, which is a downward inflection point, is maintained in an equilibrium state by the elastic repulsive force of the linear motion cam pressure spring 60, and the mating protrusion 82 of the rotation cam 80 moves along the inclined plane from the point B to the point A as a toilet seat. When the opening 20 is abnormally opened, the elastic repulsive force RF increases linearly according to the shape of the inclined surface of the stop section AB, thereby acting as a stopper by automatically returning to the point B.

As shown in FIG. 9, the pressure section BC is a section in which the user rotates the toilet seat 20 by applying a predetermined force in order to use the left toilet bowl. Upward inflection point moves to point C.

At this time, in order for the user to rotate the toilet seat 20 to the point C as the B point, the user corresponds to the force of the elastic repulsive force (RF) which increases linearly according to the inclined surface shape of the friction force (FF) and the pressure section (BC). Torque must be applied.

As shown in FIG. 10, the acceleration section CD is rotated by the weight of the toilet seat 20 by its own weight even when the user does not apply a force to rotate the toilet seat 20. The forming protrusion 82 moves from the point C, which is the inflection point, to the point D along the downward slope, and is accelerated by the elastic repulsive force FF of the linear motion cam pressure spring 60, thereby rapidly and automatically rotating.

As shown in FIG. 11, the damping section DE is rotated while the toilet seat 20 is accelerated by its own weight and elastic repulsive force (RF) at a constant speed and then accelerates by the weight of the toilet seat while passing through the point D, which is a downward inflection point. The rotational force is offset by the friction force of the elastic repulsive force (FF) that increases linearly according to the frictional force (FF) and the shape of the inclined surface to form a balance of force and to slow down smoothly at the point E.

Therefore, in the process of lowering and opening the toilet seat 20 of the bidet 1, a predetermined section is automatically accelerated and opened to shorten the opening time, and the toilet seat 20 is connected to the upper toilet seat by the rotational force generated by its own weight. By preventing the collision has the effect of preventing noise and damage.

12 to 16, the process in which the toilet seat 20 is rotated and opened from the upper toilet seat is divided into sections according to the shape of the pressure inclined plane 76 of the linear motion cam 70. I will explain it.

As shown in FIG. 12, the friction inclined surface 83 of the rotation cam 80 is rotated by the rotation cam pressure spring 90 in all sections for moving the toilet seat 20 from the point E to the point B which is fully open. The friction force (FF) generated between the inner circumferential surface of the rotating cam inserting portion 52 of the housing 50 acts uniformly, and is generated by the interaction of the linear cam 70 and the rotating cam 80 in each section. The elastic repulsive force (RF) of the linear motion cam pressure spring (60) acts linearly in accordance with the shape of the pressure inclined surface (76).

As shown in FIG. 13, when the user lifts the toilet seat 20 to move the toilet seat 20 from the point E to the point B which is in the open stop state after using the toilet seat, the rotation interlocking with the toilet seat 20 is performed. The elastic repulsive force (RF) of the linear motion cam pressure spring 60, which was compressed while the inclined surface 82 of the cam 80 moved the inclined surface of the damping section ED from the point E of the pressure inclined surface 76 to the point D, Increased linearly allows the user to conveniently rotate the toilet seat 20 with less force. In addition, in the section after the 90 °, the toilet seat 20 is a vertical point, it starts to rotate automatically by the rotational force generated by its own weight.

As shown in FIG. 14 or FIG. 15, the rotational force accelerated by its own weight is increased to the frictional force FF and the elastic repulsive force RF linearly while the upward inflection point moves to the point C after the downward point of inflection. As a result of being attenuated by the toilet seat 20 is made to be raised at almost the same speed.

As shown in Figure 16, while moving from the point of inflection point C, which is an inflection point up to the point of inflection point B, the operation is lifted faster by the rotational force increased linearly by the rotational force and the ballistic repulsion force (RF) In the stop section AB, which is the downward inflection point, as a stopper as described above, it maintains an open stop state at point B where the rotational force due to its own weight is in balance with the sum of friction force (FF) and elastic repulsion force (RF). Do it.

Therefore, the hinge 40 is the elastic repulsive force (RF) of the linear motion cam pressure spring 60 which is linearly increased or decreased in a predetermined section in the interaction between the linear motion cam 70 and the rotation cam 80, the rotation The frictional force FF generated between the friction inclined surface 83 of the rotational cam 80 and the inner circumferential surface of the rotational cam insertion portion 52 of the housing 50 by the cam pressure spring is generated uniformly throughout the toilet seat 20. Shock force generated during the opening and closing operation of the shock absorber to prevent noise and damage caused by the impact.

In addition, the lowering speed is slightly increased at the beginning of the closing operation to lower the toilet seat 20, but after that, the deceleration effect is sequentially increased until reaching the closing end so as to be the maximum at the closing end, and the entire lowering section is By making it almost constant speed, the lowering speed is not too slow or too fast, and in the operation of raising the toilet seat 20, the toilet seat with less force is applied by the linear motion cam pressure spring 60, which has been compressed. 20 is raised, the toilet seat 20 once raised has the effect of increasing the ease of use as much as possible, such as to act as a stopper not to be closed again unless an external force is applied.

In addition, even if the pressure inclined surface 76 is worn by the friction, the friction inclined surface 83 is pressed against the inner peripheral surface of the open end side of the housing 50 by the rotating cam pressure spring 90 so as to continuously generate a uniform friction force. .

In addition, the lubricating oil injected between the friction inclined surface 83 and the inner circumferential surface of the housing 50 by the oil groove 84 formed on the friction inclined surface 83 is continuously distributed by friction. To prevent wear and to reduce the friction noise generated during rotation.

As described above, the present invention has the effect of removing the impact noise and damage factors by eliminating the shock caused by the descending speed is accelerated by the weight of the toilet seat more than a certain falling angle.

In addition, when the toilet seat is lowered, the descending speed is slightly increased at the beginning of the closing operation, but since then, the deceleration effect is sequentially increased until the closing end is reached, so as to be the maximum at the closing end, and the entire descending section is almost constant at the same speed. By setting the angle, the descent speed is not too slow or too fast, and when raising the toilet seat, the toilet seat is lifted with less force by the linear spring cam compression spring that was compressed in the closed state. The true toilet seat has the effect of maximizing convenience in use, such as acting as a stopper so that it does not close again unless external force is applied.

In addition, the above-mentioned effect is that the deceleration effect generated directly in the rotational direction of the toilet seat and the deceleration effect generated in the straight section where the rotational movement is changed to linear motion by cam action when the toilet seat rotates are complementary in the entire opening and closing section. It has the effect of being implemented based on the operation.
