[0001] Toggle dowel and toilet seat hinge with a toggle dowel

[0002] Description

[0003] The invention relates to a hinged dowel for fastening a toilet seat joint according to the preamble of patent claim 1 and to a toilet seat joint constructed with such a hinged dowel.

[0004] The applicant's publication DE 202 14 888 U1 describes a generic toilet seat joint – also called a seat hinge – by means of which a toilet lid and a toilet seat are hingedly connected and attached to a ceramic element. The ceramic element has mounting holes designed as through-holes, into each of which a fastening pin of the toilet seat joint can be inserted. The actual toilet seat assembly is then placed on a pin section of the fastening pin projecting from the ceramic element. An end section of the fastening pin, which extends through the mounting hole in the ceramic element, is designed as a threaded section, onto which a fastening nut is placed in the known solution.A hinged bracket is located on the back between the ceramic and the fastening nut. When inserted into the ceramic, this bracket is placed approximately along the outer circumference of the fastening pin. After insertion, it is moved transversely so that it can be used to tighten the fastening nut. Once tightened, it rests flat against the underside of the ceramic. The fastening pin, the lock nut, and the hinged bracket thus form a type of "folding dowel," similar to the one used in the current TakeOff® seat joints from Hamberger Sanitary GmbH, which utilize a modified version of the hinged bracket.

[0005] A disadvantage of these conventional toggle anchors is that the fastening nut can come loose during dismantling or improper assembly, so that the nut and possibly also the folding bracket fall off and, in the worst case, for example when using a so-called hollow ceramic, get lost.

[0006] In contrast, the object of the invention is to create a hinged dowel and a toilet seat hinge in which the installation safety is improved.

[0007] This problem is solved with regard to the toggle plug by the features of patent claim 1 and with regard to the toilet seat joint by the features of the independent patent claim 10.

[0008] Advantageous further developments of the invention are the subject of the subclaims.

[0009] The toggle anchor according to the invention is used to attach a toilet seat hinge to a ceramic rim and has a fastening pin with a pin section on the seat hinge side and a threaded section. The latter is in threaded engagement with a counter element. The toggle anchor is further designed with a hinged bracket, which, in a locked position, is aligned transversely to the axis of the fastening pin and, in an inserted position, rests approximately flush with the outer circumference of the fastening pin. According to the invention, the hinged bracket is pivotally mounted on a pivot axis arranged transversely to the longitudinal axis of the fastening pin.

[0010] This pivot axis is preferably formed by the counter element, which is in threaded engagement with the threaded section of the fastening pin.

[0011] The construction of the toggle anchor is particularly simple if this counter element is designed as a cross bolt through which the threaded section passes.

[0012] The loss resistance can be further improved if the inventive

[0013] The toggle bolt is designed with an axial locking mechanism that prevents the threaded engagement between the counter element and the threaded section from loosening. This prevents accidental loosening of the counter element. This axial locking mechanism can be achieved, for example, by caulking.

[0014] Installation is further simplified if the folding bracket has a weight leg and a stop leg, between which a pivot bearing is formed through which the cross bolt passes. Preferably, the mass and / or dimensions of the two legs are selected so that the folding bracket aligns itself in the direction of the vertical insertion position due to gravity.

[0015] The two legs (weight leg and stop leg) are designed in such a way that the weight leg points downwards after pivoting in the direction of gravity.

[0016] A further simplification of the assembly can be achieved if a stripping arm is formed on one end section of the stop leg, which is designed to be brought into contact with the ceramic after the fastening pin has been inserted into the mounting hole of the ceramic in order to pivot the folding bracket into the locking position.

[0017] The construction of the folding bracket is particularly simple if the stop leg is designed to project in the insertion position in a radial direction at an angle to the pin section, ie towards the ceramic.

[0018] To simplify assembly, the radial projection of the stop leg is preferably smaller than the radius of the ceramic mounting hole.

[0019] The toilet seat hinge according to the invention is designed accordingly with such a hinged dowel. Preferred embodiments of the invention are explained in more detail below with reference to schematic drawings. They show:

[0020] Figure 1 is a schematic representation of a toggle plug according to the invention being inserted into a ceramic;

[0021] Figure 2 is a detailed view of a hinged bracket of the hinged dowel according to Figure 1;

[0022] Figure 3 is a detailed view of a cross bolt of the toggle anchor according to Figure 1;

[0023] Figures 4a, 4b, 4c and 4d show the assembly steps when attaching the toggle plug to a ceramic and

[0024] Figure 5 shows a situation during disassembly of the toggle anchor according to the invention.

[0025] Figure 1 shows a schematic individual representation of a toggle anchor 1 according to the invention, which is intended for fastening a toilet seat hinge to a ceramic element 2 (shown only in outline). The toggle anchor 1 has a fastening pin 4 which is designed with a pin section 6 and a threaded section 8. A cover rosette 10 is fastened to the pin section 6 and, after assembly, rests on the support surface 12 of the ceramic element 2, which is located at the top in Figure 1. As indicated in Figure 1, a seal or washer 14 can be inserted between them. A folding bracket 16 is pivotally mounted about a cross bolt 18 on the threaded section 8 of the fastening pin 4. Figure 1 shows the folding bracket 16 in an insertion position in which it is oriented vertically according to the view in Figure 1 and which enables the toggle anchor 1 to be inserted into a mounting hole 20 in the ceramic element.As will be explained later with reference to Figures 4 and 5, the toggle plug 1 can be pivoted during assembly from the vertical insertion position in the direction of arrow S (Figure 1) by approximately 90°, so that it is arranged transversely to the axis of the fastening pin 4 and can then be brought into contact with an underside 22 of the ceramic 2 from below.

[0026] Figure 2 shows an individual view of the folding bracket 16 according to Figure 1. Accordingly, it is designed with a pivot bearing 24 which is guided on the outer circumference of the cross bolt 18. The pivot bearing 24 divides the folding bracket 16 into a weight leg 26 and a stop leg 26, which points downwards in the illustration according to Figure 2. In cross section, the two legs are approximately U-shaped, with the base of the U-profile on the weight leg side being provided with the reference numeral 30 in Figure 2. The clear width of this U-profile is designed such that sections of the fastening pin 4 (indicated by dashed lines in Figure 2) are encompassed.

[0027] The mass and geometry of the weight leg 26 and the stop leg 28 are designed such that, without the influence of additional forces, gravity alone causes the folding bracket 16 to pivot around the cross pin 18 such that the weight leg 26 points downward (view according to Figure 1 or 2). For this purpose, it is heavier and / or longer than the stop leg 28 located at the top in Figure 2. This pivoting is supported in the illustrated embodiment by the stop leg 28 being designed with a constriction 32, which reduces its weight.

[0028] At the upper end section of the stop leg 28, a scraper arm 34 is formed which, in the illustration according to Figure 2, projects obliquely upwards and which has a radial extension r which is less than the radius R (see Figure 1) of the mounting hole 20. Accordingly, during assembly, the threaded section 8 with the hinged bracket 16 pivotably attached thereto can be inserted into the mounting hole 20.

[0029] Figure 3 shows a detailed view of the cross bolt 18, which does not protrude, or only slightly protrudes, beyond the outer contour of the hinged bracket 16. This cross bolt is diametrically designed with a threaded bore 36 that engages the thread of the threaded section 8. In the illustrated embodiment, an end face 38 is optionally designed with two lateral bevels 39.

[0030] The assembly of a toilet seat hinge is explained using figures 1, 4a, 4b, 4c and 4d.

[0031] First, the toggle bolt 1 of the toilet seat joint (the latter not shown) is inserted into the mounting hole 20 according to Figure 1 with the vertically adjacent folding bracket 16, wherein the cross bolt 18 is located at the end of the threaded section 8 and the weight leg 26 thus projects downwards beyond the end of the threaded section 8 (view according to Figures 1, 4a). Loosening of the threaded engagement between the cross bolt 18 and the threaded section 8 is prevented by a caulking 40 visible in Figure 4d. Instead of this, a different thread or a subsequently applied axial lock can be used. According to Figure 4a, the toggle bolt 1 is inserted into the mounting hole 20 until the entire folding bracket 16 with the wiper arm 34 is located below the underside 22 of the ceramic 2.

[0032] According to the assembly steps shown in Figures 4b and 4c, the fastening pin 4 is then pulled upward in the direction of the arrow so that the stripping arm 34 runs onto the underside 22 of the ceramic 2 and the hinged bracket 16 is pivoted about the transverse bolt 18. This pivoting occurs as the fastening pin 4 is further pulled out until the hinged bracket 16 is arranged in the locked position shown in Figure 4d, transverse to the longitudinal axis of the fastening pin 4, and thus rests against the underside 22 of the ceramic 2.

[0033] In a further assembly step, the cross bolt 18 is then screwed upward using the lever arm of the hinged bracket 16, whereby a profile 42 of the threaded section 8 allows the use of a counter-tightening tool. This tightening then continues until the hinged bracket 16 rests flat and pre-tensioned against the underside 22 and the cover rosette 10 of the hinged anchor 1 and, if applicable, the seal 14 rest on the support surface 12.

[0034] Disassembly proceeds in reverse, whereby, as shown in Figure 5, the cross bolt 18 is first adjusted downwards in the direction of the caulking 40 (see Figure 4d), preferably with the aid of the transversely positioned hinged bracket 16. After this adjustment, the hinged bracket 16 automatically pivots back into its inserted position (vertical) due to gravity. Accidental loosening of the cross bolt 18 and the hinged bracket 16 is prevented by running into the caulking 40 or other axial securing means. The toggle anchor 1 can then be pulled out of the mounting hole 20.

[0035] By means of the toggle dowel according to the invention and a WC seat joint designed with such a toggle dowel 1, the installation safety can be reduced compared to conventional solutions with minimal device-related expenditure.

[0036] Disclosed are a folding dowel 1 and a toilet seat joint constructed with such a folding dowel, in which a folding bracket 16 is pivotally mounted on a fastening pin 4.
