Description

Fixing device for toilet seat

The present invention relates to a fixing means for a toilet seat, and more specifically, to a fixing device for fixing a seat coupled to a toilet.

The toilet is provided with a seat for the user to stand up on the toilet or rotate to sit down depending on the case of using it standing up and using it while sitting on the basis of the male user.

A variety of methods for coupling the seat to the toilet have been developed, and the most common method is to couple the seat to a joint formed in the toilet with bolts and nuts.

The above fixing method commonly requires an assembly process of tightening the nut, and in the installation process, insert the bolt so that the fixing hinge of the seat is interposed between the bolt and the toilet. The male thread of the bolt must be accurately matched to the female thread of the nut and rotated. If the thread is not properly engaged, the inconvenience of releasing the nut and repeating the process of aligning the thread from the thread inevitably occurs.

For example, as disclosed in Republic of Korea Utility Model Registration No. 0488209 (announcement dated December 27, 2018), in the adjustable seat fixing device for a toilet, the support block is seated on the upper part of the installation hole, and the support block is located on the upper part of the support block. A hinge pin connected to the toilet seat is provided, an accommodating groove opened in one direction is formed inside the support block, and a binding hole communicating with the installation hole and a locking concavo-convex member are formed at the bottom of the accommodating groove. ; A head is provided on the upper portion to engage and release operation according to the rotation angle with the body unit and is inserted into the receiving groove through the binding hole, and the seating uneven member and the installation hole forming meshing with the engaging uneven member at the lower portion of the head A technology comprising a bolt unit provided with a bolt body to be inserted and connected to and a nut unit fastened to a bolt body exposed downward of the toilet pottery through the installation hole so that the body unit can be firmly fixed to the toilet pottery, There is a method in which the seat is fixed according to the tightening of the

As another fixing method, as published in Republic of Korea Utility Model Registration No. 1301592 (announcement dated August 29, 2013), the toilet seat fixing device is a seat fixing device mounted on the installation hole of the toilet pottery. Consists of a body and a fixing bolt penetrating the through hole, the body, the upper end of the upper stopper extending outwardly; a guide portion corresponding to the installation hole of the pottery positioned under the upper stopper; a fixed foot positioned below the guide part and elastically inserted into the opening formed in the central portion of the body, the fixed foot having a fixed jaw at the upper end; and a tightening portion into which a nut having a threaded portion formed inside the lower end of the body is inserted and fixed. According to the present invention, when fixing the toilet seat to the installation hole of the toilet, there is a structure in which the bolt is tightened only at the upper part, and there is also a fixing method in which a separate body is interposed rather than simply fastening the nut to the bolt.

Therefore, there is a need for a faster and more convenient fixing device, rather than a coupling method of tightening the bolt with a nut.

It is not limited, and the terms used are also only for describing the embodiment in detail, and should not be construed as being limited to the term.

As shown in the drawings, the fixing means for the toilet seat according to the present invention includes an expansion part 10 configured to be inserted into the coupling hole 105 of the toilet 100 to press the inner surface of the coupling hole 105, and the expansion The locking part 20 configured to fix the seat fixing part 103 for the toilet 100 at the upper part of the part 10 and the expansion space part 11 formed in the expansion part 10 are caught in communication with each other. It is characterized in that the fluid injection hole 21 configured in the fixing part 20 is included.

In addition, the expansion part 10 further includes a pressing protrusion 13 configured on the outer surface of the expansion part 10 so that it has a protrusion pressing surface 14 that is in close contact with the inner surface of the coupling hole 105 when it is expanded. can be characterized as

In addition, the expansion part 10 is larger than the inner diameter of the coupling hole 105 during expansion, characterized in that it further includes a locking protrusion 15 configured in the lower part of the expansion part 10 to be caught at the lower end of the coupling hole 105. can

In addition, it may be characterized in that a long hole 104 configured in the seat fixing part 103 is further included so that the inflating part 10 is inserted to correct the position where the seat 101 is installed in the toilet 100 .

The fixing means 1 for a toilet seat having the above configuration will be described in more detail along with its actions.

The seat 101 for the toilet 100 should be able to be rotated to stand up or to lie down according to the user's purpose of using the toilet 100 .

As shown in FIG. 1, a seat fixing part 103 fixed to the toilet 100 and coupled with the seat 101 and a hinge 102 is further provided so that the seat 101 is rotated from the toilet 100, The sheet fixing part 103 may be provided in plurality to correspond to the number of hinges 102 formed on the sheet 101 or may be formed as one sheet fixing part 103 as shown in the drawing.

The toilet 100 is provided with a coupling hole 105 for coupling the seat fixing part 103. Since the toilet 100 has a different design for each manufacturer, the size of the toilet 100 is inevitably different.

The position of the seat 101 and the toilet 100 when an arbitrary seat 101 is installed in the toilet 100, except when the manufacturer provides a dedicated seat 101 tailored to the design of each toilet 100. In order to correct the installation position of the seat 101 according to the shape of the toilet 100, as shown in FIG. In order to correct the installation position of the seat 101 according to the shape of the toilet 100 by allowing the position of the seat 101 to be slightly adjusted back and forth when installing the toilet seat in the toilet 100, use the above long hole 104 to fix the seat. It becomes possible to correct the position of (103).

In order to fix the seat fixing part 103 to the coupling hole 105 of the toilet 100, a separate fixing means 1 is provided in the present invention, unlike the general use of bolts and nuts.

In the present invention, the fixing means (1) has an expansion part (10) and a locking part (20) is formed on the top of the expansion part (10).

The material of the fixing means 1 is preferably made of a synthetic resin having elasticity such as rubber or silicone and easy to change shape.

An expansion space 11 is formed inside the expansion part 10 , and the expansion space 11 is configured to communicate with the fluid injection hole 21 formed in the middle of the locking part 20 .

The configuration of the fixing means 1 will be described below along with the process of coupling the seat 101 to the toilet bowl 100 .

When the fixing means 1 is inserted into the long hole 104 from the top of the seat fixing part 103 as shown in FIG. Penetrates and protrudes to the lower part of the sheet fixing part 103, and the diameter of the engaging part 20 formed at the upper end of the fixing means 1 is formed wider than the width of the long hole 104 of the sheet fixing part 103, The locking part 20 is caught on the upper surface of the seat fixing part 103 so that the expansion part 10 protrudes downward only by a predetermined length.

The expansion part 10 protruding downward is inserted into the coupling hole 105 of the toilet 100 so that the seat fixing part 103 is seated in the toilet bowl 100 .

The above process may be changed in order to be seated at any position of the seat fixing part 103 on the toilet 100, and then the fixing means 1 may be coupled with the long hole 104 of the seat fixing part 103. do.

By moving the seat fixing part 103 as much as the flow interval of the long hole 104 , the seat 101 position is corrected to be appropriate in the toilet 100 .

When the position of the seat 101 is confirmed, as shown in (A) to (C) of FIG. 3B, the fluid supply nozzle 200 of the fluid injection equipment separately prepared with the fluid injection hole 21 formed in the fixing means 1 ) to supply the fluid to the expansion space 11 .

At this time, to more easily determine the position of the fluid supply nozzle 200 in the fluid injection hole 21, the fluid injection hole 21 is further provided with a concave nozzle guide groove 22 so that the fluid supply nozzle 200 is more easily and accurately to be inserted into position.

At this time, the fluid supplied from the fluid supply nozzle 200 to the expansion unit 10 may be supplied by compressing air, but this is not limited to gas and various fluids may be used as needed, instead of the expansion unit. (10) It would be desirable to inject a fluid with a small change in volume in order to prevent it from shrinking again in response to a change in temperature.

The fluid injection equipment separates the fluid supply nozzle 200 as shown in (D) to (E) of FIG. 3B when the supply of the fluid is finished, and the fluid injection hole 21 is naturally compressed by the force expanding therein. is sealed, and if the fluid leaks from the fluid injection hole 21 and the pressure inside the expansion space 11 is lowered unintentionally, the fluid is injected as shown in (B) of FIG. 3A The ball 21 may be further treated with the sealing 23 by bonding or the like.

As the fluid injection equipment, various ready-made products such as a manual air pump or an automatic compressor can be applied, and since the fluid injection equipment is not the gist of the present invention, a detailed description thereof will be omitted.

When the fluid is injected into the expansion space 11 , the expansion part 10 elongated vertically expands in an approximately oval shape as shown in (B) of FIG. 3A .

Therefore, the pressing surface 12 provided on the outer surface of the expansion part 10 is in close contact with the side from the inside of the coupling hole 105 formed in the toilet 100, and the inner surface of the circular through hole is pressed against the pressing surface 12 . Since the radial pressure is uniformly applied, the fixing means (1) is firmly coupled in the coupling hole (105).

In another embodiment, as shown in FIG. 4 , a pressing protrusion 13 may be further provided on the outer surface of the expansion unit 10 .

As shown in (a) of Figure 4, even if the projection pressing surface 14 of the pressing projection 13 is not parallel to the inner surface of the coupling hole 105 in the longitudinal direction in the contracted state of the expansion part 10, As shown in (b) of FIG. 4 , when the fluid is supplied to the fluid injection hole 21 by the fluid supply nozzle 200, the expansion part 10 expands.

Since the operation of the fluid supply nozzle 200 is the same as that previously described with reference to FIG. 3B , the description of the fluid supply process will be omitted.

When the expansion part 10 expands and the pressing protrusion 13 expands to the extent that it touches the inner surface of the coupling hole 105 of the toilet 100, the protrusion pressing surface 14 of the pressing protrusion 13 becomes the coupling hole ( 105) is provided so as to be parallel to the inner surface in the longitudinal direction.

When the pressure protrusion 13 is described in more detail, when the expansion unit 10 is inflated according to the supply of fluid, it rotates rather than simply moves in position. The pressing protrusion 13 formed on the outer surface of the upper part and the lower part of the inflatable part 10 is the coupling hole of the toilet 100 when the pressing protrusion 13 is expanded when the inflating part 10 is expanded. When the expansion part 10 contracts to face the coupling hole 105 from the inside in parallel with the coupling hole 105 from the inside, the angle of the protrusion pressing surface 14 should be formed.

Therefore, as shown in FIG. 3a, when only the pressing surface 12 of the oval expanded part 10 is pressed, the part that swells the most in the expandable part 10 (mainly the middle part in case of vertical symmetry) is the coupling hole ( On the other hand, when the pressure projection 13 is formed as shown in FIG. 4 , the upper portion and the lower portion that do not swell much in the expansion unit 10 are also combined by the pressure projection 13 . Since it is possible to sufficiently press the inner surface of the ball 105, the fixability can be increased.

In addition, although not shown in the drawings, it may be implemented to further include a non-slip function by performing a non-slip process on the protrusion pressing surface 14. more will be included.

In another embodiment, as shown in FIG. 5 , a radially engaging protrusion 15 may be further provided at the lower portion of the expansion unit 10 .

Since the locking projection 15 has an outer diameter smaller than the inner diameter of the coupling hole 105 of the toilet 100 before the expansion part 10 expands, it interferes with inserting the fixing means 1 into the coupling hole 105 . It does not become an element, and even if the outer diameter of the locking protrusion 15 is slightly larger than the inner diameter of the coupling hole 105 , the expansion part 10 can be inserted by pressing the volume of the expansion space part 11 .

However, when a fluid is supplied to the expansion unit 10 and the expansion unit 10 expands, the pressing surface 12 not only presses the inner surface of the coupling hole 105 as in the above-described embodiment, but also the expansion unit 10 ) formed in the lower portion of the locking projection 15 is also spread radially.

By forming the expansion space 11 closer to the lower part, the locking protrusion 15 formed at the lower part of the expansion part 10 is formed to open easily according to the expansion of the expansion part 10 .

Therefore, as the expansion part 10 expands, the radially unfolded locking protrusion 15 acts farther from the center of the fixing means 1 (increasing in diameter) compared to the locking protrusion 15 before expansion. The toilet 15 is induced to be formed larger than the inner diameter of the coupling hole 105 of the toilet 100 .

Therefore, as shown in (b) of FIG. 5, the locking protrusion 15 is caught at the lower end of the coupling hole 105, so that the fixing means 1 is more firmly coupled to the coupling hole 105, so that the seat fixing part It is possible to additionally prevent the 103 from being separated from the toilet 100 .

And when it is necessary to separate the fixing means (1), in the case of the conventionally used bolt and nut, if the nut is rusted or there is a lot of foreign matter in the thread between the nut and the bolt, the combined nut does not rotate at all from the bolt, or some There could be a problem where it got caught while rotating and could not be solved.

However, in the present invention, when the fixing means 1 is to be separated, a fluid supply means is not provided in a nozzle similar to the fluid supply nozzle 200, and although not shown in the drawings, a nozzle of a form that is communicated up and down is simply injected. If it is inserted into the ball 21 so that the expansion space 11 communicates with the outdoor air, the high pressure fluid injected into the expansion space 11 due to the pressure difference naturally falls out of the fixing means 1 . , so that the expansion part 10 is contracted, so that the fixing means 1 can be easily removed.

According to the configuration as described above, the fixing means 1 is much simpler than the bolt and nut combination when installing the seat 101 to the toilet 100, and greatly reduces the time required for installation while maintaining the fixing property. The efficiency of the installation or separation operation is increased, and since it is possible to assemble many sheets 101 in a short time, it is possible to work with a small number of people, so that the production speed is increased, the production cost is lowered, and the productivity can be dramatically increased. .

As described above, in the detailed description of the present invention, the most preferred embodiment of the present invention has been described, but various modifications are possible within the scope not departing from the technical scope of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but the protection scope should be recognized from the techniques of the claims to be described later and equivalent technical means from these techniques.
