Abstract

A pivot door hinge suitable for bath and shower screen arrangements including glazed panels with hollow profile frame / 2 members^ such a screen arrangement including a door overlapping the door frame wherein the door is width-adjustable'without dismounting the hinge and capable of opening through an angle of 180°, the hinge arrangement comprising a first leaf member'adapted to engage and protrude endwise from a first profile member forming part of the door frame, such that the protruding portion defines a first pintle formation/"and a second leaf member· defining a second pintle formation^such that the pintle formations fit one within the other for pivotal interengagement about a hinge axis lying within the plane of the door frame and concealed from the exterior, there being provided a lateral bracket extension to the second pintle formation adapted to receive a second profile member forming part of the door construction.

Description

The present invention relates to a pivot door hinge arrangement, suitable for glazed panels such as bath and shower screens.

According to the present invention there is provided a pivot door hinge arrangement between hollow profile members forming part of a glazed panel arrangement, comprising a first leaf member adapted to engage and protrude from a first profile member, such that the protruding portion defines a first pintle formation, and a second leaf member defining a second pintle formation adapted for pivotal interengagement therewith, there being provided a lateral extension to the second pintle formation adapted to receive a second profile member forming a part of the door construction. Preferably, the first pintle formation is a male formation and the second pintle formation is a female formation.

A cap member is preferably provided which limits the relative axial movement of the two leaf members.

Preferably, a pin is located along the axis of the hinge arrangement, fitting in a bore defined by the male pintle formation and the cap member. The pin preferably extends beyond the cap member *E 913548 - 3 so as to locate a third door jamb profile member perpendicular to the first profile member.

Advantageously, the pivot door hinge arrangement is 5 incorporated in a bath or shower screen comprising a laterally extendable door frame, such that the effective width of the door within the door frame opening may be adjusted by moving the door laterally with respect to the hinge.

A preferred embodiment of a pivot door hinge arrangement in accordance with the invention will now be described with reference to the accompanying drawings, in which Figure 1 is a perspective sketch of a pivot door hinge arrangement in accordance with the invention, Figure 2 is a plan view from above showing the door in a closed condition, Figure 3 is a plan view from above showing the door in a partially open condition, Figure 4 is a plan view from above showing the door fully open Figure 5 is a front end elevation, in which the hinge leaves are in line, Figure 6 is a side elevation of the arrangement shown in Figure 5, viewed in the direction of arrow A, Figure 7 is a longitudinal cross-section of the detail shown in Figure 6, when viewed on section line B-B of Figure 2, and Figure 8, is a plan view from above of the detail shown in Figures 6 and 7.

Referring to the drawings, a frame arrangement comprising glazed panels which hinge together includes a hollow male profile - 4 member 1 which fits into a lower section of a hollow female profile member 2. The female profile member 2 is approximately twice the height of the male profile member 1. The profile members 1, 2 are thus telescopic, allowing for the width of the frame arrangement to be adjusted.

A first leaf member 3 of the hinge arrangement comprises a plug portion 4 which inserts into the upper section of hollow female profile member 2, and a protruding male pintle formation 5 which extends outside the profile member 2 (see Fig. 7). The leaf member 3 also defines a flange portion 6 which fits over the end of the profile member 2 and two leg portions 7, 8 which extend out over the sides of the hollow male profile member 1 (see Fig. 1). The leaf member 3 is preferably of plastics material and is bonded to the hollow profile members 1, 2 using silicon sealant. Small recesses may be provided along or inside the edges of the leaf member 3 to key and hide the silicone sealing compound, if desired.

A second leaf member 9 comprises a female pintle formation 10 which sits on top of the male pintle formation 5 and is pivotal therewith, and has a lateral extension portion 11 which extends out to one side of the assembled profile members 1, 2 (see Figs. 5 and 8). The extension portion 11 defines a shoulder 12 on which a third hollow profile member 13 is located, and fixed thereto by means of a holding cap 14, which together, are screwed to the extension portion 11.

The hinge arrangement is completed by a cap member 15 which fits over the male pintle formation 5 and into a recess defined in the top of the female pintle formation 10, effectively limiting relative axial movements between pintle formations 5, 10. The cap member 15 also includes a plug portion 16 which inserts into a cylindrical upright member 17. Lastly, a pin 18 is placed in an axial bore extending through the pintle formations 5, 10 and into locating groove 19 defined in the middle of the cylindrical profile member 17 (see Fig. 7).

The upper side of profile member 2, the upper side of profile member 13, and one side of upright profile member 17 each define a groove adapted to receive the edge of a glazed panel.

The panel or door 18 supported by the profile member 13 may be swung about the pivot hinge assembly described above from an open position parallel and adjacent to the fixed panel 19 supported by the profile members, 2, 17, (see Figure 4) to a closed position over the profile member 1, parallel with and almost in line with the fixed panel (see Figure 2). The profile member 1 thus acts as a door saddle.

The width of the door frame opening may be made smaller by sliding profile member 1 inside profile member 2. The effective width of the door may accordingly be adjusted by unscrewing and removing holding cap 14, moving the door panel sideways by the required amount and replacing holding cap 14. This will not interfere with the functioning of the pivot door hinge.

Another advantage of the pivot door hinge described above is that the whole hinge is concealed from view, and furthermore flange portions 6 and legs 7, 8 serve the function of continuing the line of the profile member 17 down to the base of the arrangement which is pleasing from a design viewpoint.

Claims

1. A pivot door hinge arrangement between hollow profile members forming part of a glazed panel arrangement, comprising a first leaf 5 member adapted to engage and protrude from a first profile member, such that the protruding portion defines a first pintle formation, and a second leaf member defining a second pintle formation adapted for pivotal interengagement therewith, there being provided a lateral extension to the second pintle formation adapted to receive a second 10 profile member forming part of the door construction.

2. A pivot door hinge arrangement as claimed in claim 1 wherein the first pintle formation is a male formation and the second pintle formation is a female formation.

3. A hinge arrangement as claimed in claim 2 further comprising a cap member which limits the relative axial movement of the two leaf members. 20
