Toilet with seat that tilts when lifting the lid

Abstract

The invention relates to a toilet that comprises a bowl, a lid and a seat, wherein the seat and the lid are hingedly connected to one another, comprising means for generating a torque housed in the hinged joint between the lid and the seat of the toilet, wherein said means for generating the torque are such that the torque generated by separating the seat from the lid is greater than the torque generated in the hinge joining the lid and the seat due to the action of gravity, allowing the use of a torsion spring secured by the two ends thereof to separate portions and secured to the lid and to the seat, or a leaf spring that can be twisted, wherein each of the ends of the torsion spring or of the leaf spring is housed and secured in a first bushing and a second bushing, both of which are independent, and wherein the first and second bushings have means for securing to housings formed on the lid or the seat that make up the hinged joint.

Claims

1. A toilet seat, comprising a hinged joint in an axis between a lid and the toilet seat, means for generating a torque housed in the hinged joint, the means for generating torque being a torsion spring or a leaf spring, the means for generating the torque having a first end secured or housed in a first bushing or cylindrical casing within in the hinged joint and a second end secured or housed in a second bushing or cylindrical casing within the hinged joint, the first bushing and the second bushing rotating independently from each other, and the first bushing or cylindrical casing and the second bushing or cylindrical casing having means for securing the respective first bushing or cylindrical casing and the second bushing or cylindrical casing to complimentary housings formed on the lid or the toilet seat wherein said means for generating the torque provides that a torque provides that a torque generated by separating the seat from the lid is greater than a torque generated in the hinged joint joining the lid and the toilet seat due to action of gravity such that the toilet seat tilts when lifting the lid.

2. The toilet with seat according to claim 1, wherein the means for generating the torque is the torsion spring that has the first end secured to the first bushing and the second end secured to the second bushing.

3. The toilet seat according to claim 1, wherein the means for generating the torque is the leaf spring that has the first end housed in the first bushing the second end housed in the second bushing.

4. The toilet seat according to claim 1, wherein the means for securing the first bushing or cylindrical casing to the housing of the lid or the toilet seat is a notch formed on the first bushing and able to be housed in the complementary housing of the lid or the toilet seat.

5. The toilet seat according to claim 1, wherein the means for securing the second bushing or cylindrical casing to the housing of the lid or the toilet seat is a perforation formed in the second bushing.

Description

DESCRIPTION OF THE FIGURES

(1) As a complement to the description provided herein, and for the purpose of helping to make the features of the invention more readily understandable, in accordance with a preferred practical exemplary embodiment thereof, said description is accompanied by a set of drawings which, by way of illustration and not limitation, represent the following.

(2) In FIG. 1, points A), B), C) show different illustrations of the actuation of a torsion spring.

(3) In FIG. 2, points A), B) and C) show the embodiment of the leaf spring.

(4) FIG. 3 shows a connection between the lid and the seat of a toilet.

(5) FIG. 4 shows a leaf type spring positioned along the hinge axis.

PREFERRED EMBODIMENT OF THE INVENTION

(6) In light of the figures, a preferred embodiment of the proposed invention is described below.

(7) FIG. 1 shows a first embodiment of the means for generating a torque, which is by means of a torsion spring (1) housed and secured by each of the ends thereof in bushings or cylindrical housings able to be housed in the hinged joint between the lid and the seat, wherein said bushings are a first bushing (2) and a second bushing (3), both of which are able to rotate independently with respect to each other.

(8) The torsion spring (1) has a first end (1.1) secured to the first bushing (2), and it also has a second end (1.2) secured to the second bushing (3).

(9) Each one of the bushings or cylindrical housings has retention or securing means in housings defined to that effect both on the lid and on the seat respectively, wherein said housings in combination with the bushings make up a hinge capable of generating a torque between the lid and the seat when both are separated and wherein said torque is greater than the torque generated due to the action of gravity.

(10) Thanks to the described configuration, a double functionality is achieved since the means for generating a torque act at the same time as a hinge axis between the lid and the seat, the structural modifications that have to be carried out in the elements manufactured up to now being nil.

(11) In the embodiment shown in FIG. 1, the means for securing the first bushing (2) to a housing provided in the lid or in the seat consist of a notch (4) housed in a recess with the complementary shape, while the means for securing the second bushing (3) to a housing provided in the lid or in the seat consist of a perforation (5).

(12) FIG. 2 shows a second embodiment of the means for generating a torque that is by means of a leaf spring (6), which is a system of tempered steel sheets that fulfils the same function as the torsion springs. Said leaf spring (6) has a first end (6.1) housed in the first bushing (2), while the second end (6.2) of the leaf (6) is housed in the second bushing (3), both bushings rotating independently.

(13) Each of the bushings (2) and (3) also have means for securing to each one of the housings defined in the lid and in the seat.

(14) FIG. 3 shows the lid (7) and the seat (8) and how both are linked by means of a hinged joint in which the means for generating a torque are housed, through each one of the bushings thereof.

(15) FIG. 4 shows how the leaf spring (6) runs along the axis joining both elements.

(16) Having thus adequately described the nature of the present invention, as well as how to put it into practice, it must be noted that, within its essential nature, the invention may be carried out according to other embodiments differing in detail from that set out by way of example, which the protection sought would equally cover, provided that the fundamental principle thereof is not altered, changed or modified.
