Description

Technical Field

[0001] The present disclosure relates to a hinged support structure for a toilet cover unit, to a toilet cover unit comprising such a support structure and to a toilet comprising such a toilet cover unit.

Background

[0002] A known support structure comprises an attachment base for attachment to a bowl part of a toilet, a separate hinge mechanism, and a fastener for fastening the hinge mechanism to the attachment base. The hinge mechanism has a threaded blind hole, and the attachment base has a through hole, through which the fastener is inserted to engage the blind hole. Thus, the head of the fastener will be positioned at the underside of the attachment base such that it is concealed by the attachment base, and extend upwardly.

[0003] Other types of toilet seat support structures are known from e.g. US 6,393,624 B1, US 5,918,322 and US 6,226,805 B1.

[0004] In order to compensate for manufacturing tolerances of the toilet bowl, for different toilet bowl types and for different lid types, it is desirable to enable the position of the hinge mechanism to be adjusted relative to the toilet bowl. In particular, it is desirable to enable the hinge mechanism to be easily and quickly adjusted.

Summary

[0005] It is a general object of the present disclosure to provide an improved or alternative support structure for a toilet cover unit.

[0006] It is a specific object to provide a support structure for a toilet cover unit, which can be readily adjusted.

Fig. 2 is a schematic top view of the support structure 1 of Fig. 1.

Description of Embodiments

[0031] Referring to Fig. 1, there is illustrated an embodiment of a support structure for a toilet cover unit (not shown). The support structure comprises an attachment base 2 for attachment to a bowl part 8 of a toilet (not shown). The attachment base 2 may be attached to the bowl part of the toilet in a conventional manner, such as by a bolt (not shown) being introduced from below the bowl part (8) through a through hole 10 thereof and engaging a threaded recess 11 of the attachment base 2. Specifically, the attachment base may have one, two or more such threaded recesses, in order to allow it to be mounted in different positions relative to the through hole 10.

[0032] The support structure further comprises a hinge mechanism 2, which is formed as a separate piece from the attachment base 2, and which may be designed in different manners. In the illustrated example, the hinge mechanism 3 comprises a main body 5, which extends vertically from the attachment base, and which has a through hole 18, into which a fastener 4 may be introduced to engage the attachment base 2, in order to attach the hinge mechanism 3 to the attachment base 2.

[0033] The hinge mechanism may further comprise an axle 6, on which one or more mounting members 7a, 7b may be pivotally arranged about an axis A (Fig. 2). The axle 6 may extend substantially horizontally, when the support structure is in an assembled state on a toilet. The axle may be provided with bearings and/or lubricant to enable the mounting members 7a, 7b to pivot smoothly.

[0034] The mounting members may be arranged such that a toilet lid and/or a toilet seat (not shown) can be fastened thereto, such that the toilet lid and/or toilet seat becomes pivotable relative to the toilet bowl (not shown). In the illustrated embodiment, the mounting members 7a, 7b have through holes 17 (Fig. 2) for receiving e.g. bolts, screws or rivets (not shown) to attach a seat and/or lid thereto.

[0035] In the illustrated embodiment, the mounting members 7a, 7b are arranged on opposite sides of the main body 5 of the hinge mechanism. Furthermore, the mounting members 7a, 7b may be angled or bent upwardly and downwardly, respectively, so as to conform to the anticipated position of a toilet seat and a toilet lid respectively.

[0036] A fastener 4 is provided for fastening the hinge mechanism 3 to the attachment base 2. The fastener may be an elongate component, having a threaded portion 14 at a lowermost portion thereof for engagement with a recess or through hole 16 of the attachment base 2, which is provided with corresponding threads 9.

[0037] An uppermost portion of the fastener may be provided with a substantially conical surface 13 designed for interaction with a correspondingly conical surface 12 of the hinge mechanism.

[0038] The conical surfaces 12, 13 may present an angle relative to a length direction L of the fastener 4, which is less than or equal to 30 degrees, less than or equal to 20 degrees, less than or equal to 10 degrees, less than or equal to 5 degrees or less than or equal to 2.5 degrees. The conicity of the surfaces 12, 13 need not be linear, but the surfaces may be shaped with a slight radius instead, as seen in a plane parallel with the length direction L of the fastener.

[0039] An upwardly facing portion 15 of the fastener may be provided with gripping means (see e.g. Fig. 2) to enable it to be manipulated by means of a screwdriver or a similar device.

[0040] The uppermost part of the fastener 4 may be shaped so as to conform to the shape of the main body 5 of the hinge mechanism. For example, it may have the shape of a partial sphere, it may be substantially flat, etc.

[0041] In addition, the fastener may have substantially the same diameter throughout its length, i.e. it does not need to have a distinct head like conventional screws or bolts.

[0042] The support structure may be arranged as a part of a toilet cover unit, which is to be installed on a toilet, e.g. on a bowl part thereof. Such a toilet cover unit may comprise two support structures 1, arranged such that their respective hinge mechanisms 3 are substantially aligned. Furthermore, such a toilet cover unit may comprise a toilet seat, which is attached to a first mounting member 7a of the support structure 1, and/or a toilet lid, which is attached to a second mounting member 7b of the support structure 1.

[0043] The toilet cover unit may form part of a toilet.

[0044] According to the present disclosure, the hinge mechanism may be attached to the attachment base 2 by arranging a fastener 4 through a through hole 18 of the hinge mechanism, such that the fastener 4 engages the attachment base 2.

[0045] The fastener 4 may threadingly engage the attachment base 2 to such an extent that the conical surfaces 12, 13 come into contact and provide a firm interconnection between the hinge mechanism 3 and the attachment base 2.

[0046] According to the present disclosure, a support structure for a toilet cover unit may be adjusted by releasing the fastener 4, which through the through hole of a hinge mechanism 3 engages the attachment base 2, adjusting a rotational position of the hinge mechanism 3 relative to the attachment base 2, and subsequently tightening the fastener 4. The method may be performed while the attachment base is fastened to a bowl part 9 of a toilet, and thus the need for dismounting the attachment base from the bowl part of the toilet has been eliminated.
