HINGE MOUNTING APPARATUS FOR THE TOILET BOWLS

Description

[0001] This invention concerns the WC seat mounting to the toilet bowls that seat mounting cannot be performed, from lower face of the toilet bowl, by the help of butterfly nuts. When the seat mounting holes are not accessible from lower face of the toilet bowl for reasons of the design of the toilet bowl; the seat can not be mounted, if the toilet bowl was permanently installed to the floor or the wall.

[0002] In prior art, by a European Patent Application EP 1177756, a device for fixing the seat assembly of a toilet bowl is disclosed. The device in EP 1177756 cannot be fixed into seat mounting hole easily, due to the long slot on the oscillating element, which causes the oscillating element moving or rotating with respect to the stem, in an uncontrolled manner while installation.

[0003] Also, after installation of the device, which is disclosed in EP 1177756, there exists a significant clearance between the stem and seat mounting hole. Even if the oscillating element is firmly tightened between the nut and the lower face of the seat mounting hole, the stem may slide or move inside the said hole. This event results in that the seat can change its initial installed position on the toilet bowl.

[0004] The subject matter invention was developed to mount the seat to the toilet bowl whose mounting holes are not accessible from lower face of the bowl. By the help of this invention, the toilet seats can easily be fixed and firmly tightened to such toilet bowls. In order to make the apparatus more user-friendly and to minimize the manufacturing cost, it was designed as simple as possible and the number of parts that forms it held in minimum. For example, a spring was not used to bring part (2) to horizontal position, indeed this function is done by shaking the apparatus by hand after insertion of it to hole (5) (Figure 1).

[0005] Another advantage of the subject matter invention is that the disclosed hinge mounting apparatus for toilet seats is firmly fixed to the toilet bowls. And the said apparatus and connected seat does not change its initial installed position on the toilet bowl.

[0006] After that point, this invention was explained more detailed by referring to the figures in appendix.

Figure 1: The position of apparatus during assembly of the toilet seat to the toilet bowl.

Figure 2: Tightening the screw during fixing hinge to toilet bowl by the help of apparatus.

Figure 3: Final assembly.

[0007] The said hinge mounting apparatus is comprised with; a bell shaped designed part (2), a cylindrical part (1), a hinge bolt (3) and a hinge body (4).

[0008] The bell shaped designed part (2) is formed from a piece of metal strip, having a longitudinal slot, such that the strip is bended to provide a semi circular surface in the mid region, and two planar surfaces a both end, of the strip. The two planar surfaces have approximately equal areas and they lie on the same imaginary plane, which is coincident with the longitudinal axis of the said semi circular surface and the line, which is the intersection of one end of the semi circular surface and related end of one of the said planar surface.

[0009] The cylindrical part (1) has a threaded thru hole whose longitudinal axis perpendicularly intersects the mid point of longitudinal axis of the cylindrical part (1).

[0010] In order to mount the hinge mounting apparatus components to each other; firstly, the hinge bolt (3) is inserted to the hole on the hinge body (4). Secondly, the hinge bolt (3) is inserted to the slot on the bell shaped designed part (2) from convex side of semi circular surface of the said part (2). Thirdly, the cylindrical part (1) is mounted to the hinge bolt (3) from the threaded hole of the said part (1) and then, the cylindrical part (1) is seated to the concave side of semi circular surface of the bell shaped designed part (2).

[0011] In order to fix the hinge mounting apparatus to the seat mounting hole of toilet bowl: as in figure 1, user inserts the bell shaped designed part (2), by tilting it, that can move or rotate on cylindrical part (1) which is screwed to the hinge bolt (3), to the seat mounting hole (5) on the toilet bowl.

[0012] Then, as in figure 2, the bell shaped designed part (2), which can be rotated on part (1), becomes to horizontal position by shaking the hinge body (4) by hand. The hinge bolt (3) is screwed as rotating it to clockwise with a screwdriver. Meanwhile, the hinge body (4) is hold upward to prevent rotating of cylindrical part (1) and the bell shaped designed part (2).

[0013] In figure 3, by tightening the hinge bolt (2) assembly is completed.

[0014] After fixing of the aparatus to the seat mounting hole, it is clear that the two ends of the semi circular surface of the bell shaped designed part (2) rigidly seated to the corner which is at the lower face of the the seat mounting hole. This type of mounting prevents the the hinge bolt (3) (and connected seat) sliding or moving in the seat mounting hole of the toilet bowl.
