Abstract

A screen (10) comprises overlapping leaves (12.1, 12.2), an upper rail (14.1) on which the leaves are hung, and a lower rail (14.2) for guiding the lower ends of the leaves during their sliding movement. A runner element (30) whereby the lower end of an outer one of the leaves is guided with respect to the lower rail, is pivotally displaceable between a first condition in which it engages with the lower rail and a second condition in which it is disengaged from the lower rail, permitting the leaf to swing away from the other leaf. This facilitates cleaning of the leaves in the region where they overlap.

Detailed ways

Referring first to FIGS. 1 to 4 . Reference numeral 10 generally denotes the enclosure screen of the bathtub 11, which consists of two overlapping screen leaves 12.1 and 12.2; an upper or head rail 14.1 on which the screen leaves are suspended and can slide along; a lower rail or bottom rail 14.2 It is used to guide the lower end of the screen leaf during the sliding process of the screen leaf. The upper rail 14.1 and the lower rail 14.2 are extruded aluminum profiles with the same profile and placed opposite to each other. Even in the fully expanded state of the screen leaves shown in Figures 1 and 2, there is a certain overlap between the screen leaves. For hidden screens in general, this can make cleaning the area of the overlap difficult. For the purpose of cleaning these areas, the screen leaves 12.2 can be tilted towards the inside of the tub, as will be described in detail below.

Both screen leaves 12.1 and 12.2 consist of toughened glass panes 15. The screen leaf 12.1 positioned at the outside of the bathtub 11 is suspended on the upper rail 14.1 by a pair of rollers 16. The rollers 16 are movable along the track 18 of the component upper rail 14.1. Screen leaf 12.1 is relatively fixed, so say, because when it slides along track 14.1 and 14.2, can not tilt like screen leaf 12.2. The lower end of the screen leaf 12.1 is guided by the lower rail 14.2 through a pair of rollers 20 . The rollers 20 are movable along a rail 22 forming the lower rail 14.2. The rollers 16 and 20 are mounted on the glass pane 15 of the screen leaf 12.1 by couplings 24'.

The screen leaf 12.2 is suspended on the upper rail 14.1 by a pair of rollers 26. The rollers 26 are movable along a rail 28 forming the upper rail 14.1. The lower end of the screen leaf 12.2 is guided by the lower rail 14.2 through a pair of sliding members 30. The slide 30 is movable along a rail 32 forming the lower rail 14.2. The rollers 26 and the sliders 30 are mounted on the glass pane 15 of the screen leaf 12.2 with couplings 34.

As can be clearly seen in FIG. 4 , the sliding member 30 has two bosses 36 protruding in opposite directions, and is installed on a pin shaft 38 , which is hinged to the coupling member 34 again. On the other side of the coupling, the pin shaft 38 has a wing handle 40, by turning the wing handle, the slider 30 can be converted in two positions, that is: the first position (as shown in Figures 3 and 4), the convex One of the stages 36 guides the lower end of the screen blade 12.2 together with the rail 32; in the second position, the slide 30 is turned by 90°. In the second position, the slider 30 is disengaged from the track 32, enabling the panel leaf 12.2 to tilt laterally away from the panel leaf 12.1 in the direction of arrow A, as shown in the upper part of FIG. In order to make this tilting movement possible, the extrusion 14.1 is located free of space above the track 28 in order to tilt the roller 26 into the position shown in FIG. 3 . To this end, an extrusion rib 42 is arranged at an angle as shown.

Part 44 is the handle of screen leaves 12.1 and 12.2.

Reference is now made to FIG. 5 . Shown is another form of slider 30.1. Each boss of the slider 30.1 has a roller 46 used to reduce the friction between the roller and the track 32 when the roller engages with the track. Under this structure, when the sliding member 30.1 rotates 90°. The rollers 46 will disengage the track 32, thereby enabling the tilting movement described above.

Referring now to Figures 6 to 20, reference numeral 50 generally indicates a hidden screen formed by three overlapping sliding screen leaves 52.1, 52.2 and 52.3. Each panel consists of a sheet 54 of toughened glass. There is an extruded aluminum profile frame 56 along the vertical edge of the glass panel. The frame 56 has stops 58 which interact to prevent the leaves from slipping away from each other as they slide, which makes it easier to clean the overlapping area between adjacent leaves in the fully deployed position of the screen, as shown in Figures 6 and 8. difficulty. In order to achieve the purpose of cleaning these areas, the screen leaves 52.2 and 52.3 have a tiltable structure as shown in the screen leaf 12.2 in Figures 1 to 4 .

The hidden screen 50 has an upper rail 62.1 and a lower rail 62.2, respectively. A pair of rollers 64 are arranged at the upper end of screen leaf 52.1, and are suspended on the upper rail 62.1. The rollers 64 are movable along a rail 66 forming the upper rail 62.1. The lower end of the screen leaf 52.1 is provided with a pair of sliding parts 68, which can move along the rails 70 constituting part of the lower rail 62.2 respectively. The rollers 64 and the sliders 68 are mounted on the frame of the screen leaf 52.1 through brackets 72. Each bracket 72 has a pair of pillars 74 (see FIGS. 17 to 20 ), which extend into the inner chamber of the frame 56, and the brackets are respectively positioned by bolts 76. A pair of legs 74 of the bracket are initially made equal in length and one of them is truncated during assembly so that it does not interfere with the glass plate 54 . One strut is shortened at one end of the screen leaf, and the other strut is shortened at the other end. Both struts 74 have a slotted hole 78 through which a bolt 76 passes. Slotted holes 78 allow the height of bracket 72 to be adjusted until bolts 76 are tightened.

The slider 68 has a single boss 80 and is coupled with a pin 82 . Pin shaft 82 is hinged with bracket 72 again. The pin has a slotted end 84 so that it can be turned with a screwdriver.

When the slider 68 is in the position shown in Fig. 10 and Fig. 20, the boss 80 engages with the track 70, thus keeping the position of the panel blade 52.1 unchanged. If the panel blade 52.1 needs to be shifted, the pin shaft 82 is rotated to disengage the boss 80 from the connection with the track 70, so that the screen blade 52.1 can be displaced (assuming that the other two panel blades 52.2 and 52.3 have been displaced).

The screen leaves 52.2 and 52.3 are similarly suspended and guided by rollers 90 at the top and slides 92 at the bottom. The roller 90 engages with a track 94 forming part of the upper rail 62.1, and the slider 92 engages with a track 96 forming part of the lower rail 62.2.

The rollers 90 and sliders 92 of the screen leaf 52.2 are installed by brackets 98, and these parts of the screen leaf 52.3 are installed by brackets 100. Bracket 100 differs from bracket 98 in that its horizontal arm is longer so that the two panels overlap each other. Their rollers 90 and slides 92 run within the same tracks 94 and 96 respectively. Each bracket 98 and 100 has a pair of legs 74 similar to bracket 72 . One of the legs is shortened during assembly to match its corresponding glass pane 54 . In addition, the structural form is similar to the above-mentioned screen leaf 52.1. In particular for height adjustment, the struts 74 likewise have slotted holes, as is the case with the brackets 72 .

It can be seen that the space above the track 94 where the upper rail 62.1 is located is unobstructed. Once the slider 92 is displaced and the track 96 is disengaged, the panel leaves 52.2 and 52.3 can be tilted.
