FASTENING SYSTEM DESIGNED FOR INSTALLATION OF SEATS AND UNITAS COVERS, AND HINGE SYSTEMS APPLICABLE IN SEATS AND UNITAS COVERS FOR SURFACES OF SANITARY WARE

DESCRIPTION

Technical field

This utility model relates to a mounting device used to install hinge systems used in seats and toilet lids, and as a result, to sanitary products with a seat and toilet lid, and the mounting device makes it easy to install seats and toilet lids on the upper surface of the sanitary products, and contains a fastener of the spider type, which allows the hinge system to counteract the weakening under dynamic loads.

Utility Model Background

Currently, the variety of seats and suitable toilet lids produced makes a difference in the way these seats and toilet lids are installed. Most toilet seats and lids are usually attached to the surface of the sanitary ware, regardless of the hinge system, using a bolt through a hole made in the surface of the sanitary ware and a nut corresponding to the specified bolt at the bottom of the surface of the sanitary ware. Today, in modern designs of toilet seats, the installation of toilet seats and lids on the surface of a sanitary product using devices in the form of bolts and nuts used in the prior art is not possible due to the reduction of cutouts on the side surfaces of the sanitary product. This situation necessitated the development of a mounting device that allows access to the holes made in the toilet seat from the same upper surface. In well-known practice, in installations carried out using a mounting hole located on the surface of a sanitary ware, butterfly-type fasteners, bolts and nuts are used.

In the designs available today, toilet seats and lids are attached to a plumbing fixture using a variety of different methods. In patent EP1177756, the part designated as “oscillating element” makes it possible to install the toilet seat and lid on the sanitary ware with bolts and nuts. However, the oscillatory fastener provided in the specified device will not be able to prevent the loosening and movement of the hinge system in response to heavy loads over time, since it does not contain a structure configured to provide prestress in the device. In documents No. DE102007010930 and No. DE20214888, fastening by means of an opening made in a bathroom / sanitary product and fixing the hinge system are carried out using various types of fasteners. In the devices described in these patents, there is provided a “butterfly” type fastener passing through an installation hole made in the bathroom / sanitary product and containing threads corresponding to a “butterfly” type bolt or fastener with a nut corresponding to the bolt in its lower parts. The fixture is carried out by pulling the fastener type "butterfly", located in these devices near the surface of the bathroom / sanitary product with a bolt. However, the fasteners used in the prior art cannot ensure the creation of prestress.

In the fastening device of this utility model, there is provided a spider-type fastener having at least four legs and made to rotate around a swivel nut, which, after passing through an installation hole made in the upper surface of the bathroom / sanitary product, is installed in a horizontal position, and fastening is provided by fixing on the bottom surface of the bathroom / sanitary ware of its racks. According to the design of the spider-type fastener, said element creates a prestress in the screw mechanism by means of its elastic and / or plastic deformation after reducing the gap between the rotary nut and the bolt. The specified prestressing has the ability to prevent the weakening of the hinge system under various dynamic loads.

Utility Model Purpose

The purpose of the utility model is to develop a fastening device that makes it possible to easily mount the hinge systems used in seats and toilet lids, as well as to easily install the seats and toilet lids on the upper surface of sanitary ware, and allowing the hinge system to counteract the weakening under dynamic loads in the case of hinge systems .

Utility Model Description

This utility model relates to a mounting device used to install hinge systems used in seats and toilet lids, and as a result, to sanitary products with seats and toilet lids, and the mounting device makes it easy to install seats and toilet lids on the upper surface of the sanitary products, and contains a fastener of the spider type, which allows the hinge system to counteract the weakening under dynamic loads.

The fastening device (A) according to the present utility model comprises a fastening bolt (1), a clamping ring (2), a swivel nut (3) and a spider-type fastener (4), which creates a prestress in the device. The rotary nut (3) has a cylindrical structure and contains a slot for placing a fixing bolt (1) in it, perpendicular to the central axis of the cylinder from the outer surface of the cylinder, and contains threads having the same dimensions as the bolt and the threaded end. The fastening element (4) contains end parts, which may be referred to as protrusions (15), which prevent the turning nut (3) from falling out and provide a firmly fixed structure.

The spider-type fastener (4), developed within the framework of this utility model, has a structure with at least four posts (8) to come into contact with the bottom surface (13) of the bathroom / sanitary product. At least two of the posts (8) are located at one end of the fastener (4), and at least two of them (8) are located at the other end. The design of the fastener (4) is shown in FIG. 7. The fastener (4) has a decreasing and increasing corrugated structure, where the concave surfaces (10) and the convex surfaces (11) follow one another. Concave surfaces (10) and convex surfaces (11) have radius bends so as to form a corrugation. A slot (9) for accommodating the fixing bolt (1) is provided in the middle of the structure, forming a corrugation in the form of concave and convex surfaces between the edges (12). The edges (12) of the fastener are connected in the concave end parts (10) near the uprights (8) after the formation of the slot (9), then are again disconnected and connected by the formation of at least two uprights (8) at both ends (Fig. 7, Fig. . 8). If you look at the fastener from the top or front surface, as shown in FIG. 7 to 7, it is noticeable that its middle part has a structure with an elevation relative to the end parts near the uprights, forming convex surfaces (11) and decreasing in the direction of the end parts, forming concave surfaces (10). The edges (12) forming a slot (9) with such a structure are connected in the end parts, forming a concave surface (10) and are located below the middle part, forming a convex surface (11), are disconnected again in the direction of the uprights (8), form racks ( 8) to come into contact with the bottom surface (13) of the bathroom / sanitary product by forming an elevation in the upward direction. Racks (8) located above relatively concave surfaces (10) with a structure also forming an elevation in the part of the rack (8), as well as the corrugation provided in this structure, allow the racks (8) to be placed in the upper direction so as to be in contact with the bottom surface of the sanitary ware. Due to the corrugated structure having such different heights of the fastener (4), the system is pre-stressed and the fastener is fastened by applying pressure to the said posts (8) due to contact with the surface of the bathroom / sanitary product. The racks (8) of the fastener are pressed on the bottom surface (13) of the bathroom / sanitary product after the fastening process is completed. The convex surface (11) formed in the middle part of a certain design of the fastener (4) developed in the framework of this utility model enters the installation hole (6) during installation and can be lifted inside the hole (6) by tightening the bolt (1), making possible, thus, a more reliable installation by pulling the specified element (4) and increasing pressure on the racks (8). In other words, the corrugated design of the spider-type fastener (4) with four legs, which is the subject of this utility model, due to its structure, makes it possible to install which is more stable against attenuation by providing prestress in the device. In the fastening device according to the present utility model, the fastening bolt (1) passes through the clamping ring (2), is located in the slot placed in the hinge system (5), passes through the slot (9) made in the middle part of the spider-type fastener ( 4), and twisted with a rotary nut (3). The indicated connection is shown in FIG. 1. The fastener (4) is able to move its lower surface (7) around the axis of the rotary nut (3) to move between its horizontal and vertical position.

In the fastening device according to the present utility model, after the fastening bolt (1) is twisted with a rotary nut (3), the spider-type fastener (4) rotates with its lower surface (7) around the axis of the rotary nut (3) so that partially or completely cover the threads of the fixing bolt (1) and assume a vertical position, as shown in FIG. 2. The fastener (4) having taken the vertical position shown in FIG. 2, passes downward in a vertical position through an installation hole (6) made in a sanitary / sanitary product, through which the seat and toilet lid will be installed on the sanitary / sanitary product, and then takes a horizontal position by rotation around the axis of the rotary nut (3) . The horizontal position of the spider mount is shown in FIG. 3. The contact of the struts (8) of the spider-type fastener (4) with the lower surface of the sanitary / sanitary ware is achieved by reducing the clearance of the fastening bolt (1), as shown in FIG. 4. Then, the spider-type fastener (4) and the swivel nut (3) assume the position shown in FIG. 5 by tightening the fixing bolt (1). In this position, the hinge system (5) is in contact with the upper surface (14) of the sanitary / sanitary ware. Racks (8) are in contact with the bottom surface (13) of the sanitary ware. The protrusions (15) of the fastener are in contact with the rotary nut (3) and the rotary nut (3) is held by the protrusions / ends (15) of the fastener (4) and is secured between the protrusions (15). After this step, if the fastening bolt (1) is tightened to the required torque, the spider type fastener (4) undergoes elastic and / or inelastic deformation due to its design and provides prestressing in the fastening device, taking the position shown in FIG. . 6. In this position, the convex surface (11) of the spider-type fastener (4) located in the middle part of its corrugated structure enters the installation hole (6) made in the sanitary / sanitary ware and can be lifted therein by tightening the bolt (1), and the device is pre-stressed, and pressure is applied to the posts (8). Thanks to the connection with the initial voltage developed in the framework of this utility model, there is a difference compared with other devices that provide a strong connection; moreover, a connection is provided that is resistant to attenuation even under dynamic loads applied to the hinge system (5).
