Description

Technical field of the invention

The invention relates to a lift-slide door comprising:

a frame consisting of a sill, a head jamb and two side jambs, which frame is placed in a wall opening during use and is fixed to the wall, whereby the sill comprises a full-length front part sloping forwards and a full-length rear part on which a full-length rail is located,
a fixed wing part located above the front part of the sill closing part of the opening delimited by the frame and fixed to the frame,
a sliding wing part located above the rear part of the sill and slidable in the frame between a closed position next to the fixed wing part in which the sliding wing part closes another part of the opening delimited by the frame, and an open position in which the sliding wing part is behind the fixed wing part and the other part of the opening delimited by the frame is open,
wheels which are present in a recess in the underside of the sliding wing part and which are movable on the rail, and
a lifting mechanism that can raise and lower the sliding wing part relative to the wheels.

Background of the invention

Such a lift-slide door is generally known. Once the known lift-slide door has been placed in a wall opening and has been fixed to the wall, it is then very difficult to dismantle the lift-slide door. Usually this can only be done in a destructive way. In the existing lift-slide doors, all kinds of parts such as guide rail and sealing strips in the frame and on the fixed leaf and on the threshold must be mounted or disassembled before assembly or disassembly can be done with the fixed part. The known lift-slide doors must also be sealed in various places (all sorts of loose profiles and transitions therein) to prevent water penetrating to the inside.

Summary of the invention

An object of the invention is to provide a lift-slide door of the type described in the preamble which is simple to assemble and disassemble. To this end, the lift-slide door according to the invention is characterized in that between the fixed wing part and the front part of the sill there is a wedge-shaped wing insert attached to the underside of the fixed wing part and adjacent to one of the side jambs, the wedge shape being such that the top of the wing insert is horizontal. Because the wing insert is attached to the fixed wing part, the fixed wing is mounted and disassembled in one operation together with the wing insert during assembly and disassembly. This is much more efficient than first attaching the wing insert to the sill and then placing the fixed wing part on the wing insert or first dismantling the fixed wing part and then the wing insert. As a result, there is no need to seal seams and profile transitions, etc. to prevent water penetration to the inside.
It is possible to work even more efficiently if a wedge-shaped central insert present between the fixed wing part and the front part of the sill is also attached to the underside of the fixed wing part. The same advantage applies to this as for the wing insert. The center insert is adjacent to the opening and is present against the wing insert and the center insert is also wedge-shaped in such a way that the top of the center insert is horizontal.
Preferably wedge-shaped side inserts are present between the side jambs and the front part of the sill, which are mounted on the sill. During assembly and disassembly, the sill is mounted and disassembled together with the side inserts, which increases efficiency. The wedge shape is preferably such that the top of the side ends is horizontal.
Gaskets are preferably present between the side jambs and the side inserts to obtain a water and moisture-tight construction.
In order to be able to drain (rain) water that can seep into the side jambs, channels are preferably present in the side inserts and in the gaskets, such that an open end of the channels communicates with the environment at the front of the sill and another open end of the channels communicates through the hole in the gasket with the space in the side jambs which are hollow.
In order to also be able to drain the (rain) water that can seep into the frame of the fixed wing part, further channels and further holes are present in the center bar and in the wing insert, via which the space in the hollow frame of the fixed wing communicates with the environment at the front of the sill.
To prevent a thermal bridge, the wing insert comprises a front part extending over the entire length, as well as a rear part extending over the entire length, the two parts being connected to each other via a bridge piece that conducts heat poorly, and the fixed wing part is present above the front part.
To make it even easier to assemble and disassemble the fixed wing part with the attached wing insert, the distance from the edge of the head jamb at the bottom and at the front of the head jamb to the edge of the front part of the sill adjacent to the rear part of the sill, is preferably smaller than the distance from said edge of the head jamb to an imaginary line parallel to said edge of the sill on the front part of the sill, so that the fixed wing part with the wing insert can be removed from the frame by rotating them around the said edge of the head jamb.
In order to be able to place the lift-slide door in the rear wall of a house without external access to the rear without having to use a crane, the sill, the head jamb and the two side jambs of the frame are detachable from each other and can then be attached again to each other.

Detailed description of the drawings

Figure 1 shows an embodiment of the lift-slide door according to the invention as seen from the outside. The lift-slide door 1 has a frame 3 with inside a fixed wing part 13 and a slidable wing part 17. The fixed wing part 13 is attached to the frame 3. The frame 3 is composed of a sill 5, a head jamb 7 and two side jambs 9. The sill 5 has a front part 5a extending over its entire length and sloping towards the front, and a rear part extending over its entire length 5b. The fixed wing part 13 is located above the front part 5a of the sill 5 and closes off part of the opening 15 defined by the frame 3. The sliding wing part 17 is located above the rear part 5b of the sill 5 and is slidable in the frame 3 between a closed position (the position shown in Figure 1) adjacent to the fixed wing part 13 in which the sliding wing part 17 closes another part of the opening 15 bounded by the frame, and an open position in which the slidable wing part 17 is present behind the fixed wing part 13 and leaves the other part of the opening 15 bounded by the frame 3 open.
Figure 2 shows a lower part of the lift-slide door in cross-section. Between the fixed wing part 13 and the sloping front part 5a of the sill 5 there is a wedge-shaped wing insert 23 which is attached to the underside of the fixed wing part 13. This wing insert 23 adjoins one of the side jambs 9. The wedge shape of the wing insert 23 is such that the top of the wing insert 23 is horizontal. In the rear part 5b of the sill there is a rail 11 which extends over the entire length of the sill. In a recess in the underside of the slidable wing part 17, wheels 19 are present, which can move over the rail 11. In the sliding wing part 17 there is a generally known lifting mechanism (not shown) which can lift and lower the sliding wing part 17 relative to the wheels 19. This lifting mechanism can be operated by a handle 21 (see figure 1).
Between the side jambs 9 and the front part 5a of the sill 5, wedge-shaped side inserts 25 are present, see figure 1. These side inserts 25 are mounted on the sill 5. Between the fixed wing part 13 and the front part 5a of the sill 5, a wedge-shaped central insert 27 is present. This central insert 27 is attached to the underside of the fixed wing part 13. The center insert 27 is adjacent to the part of the opening 15 where the sliding wing part 17 is present in the closed position and is present against the wing insert 23. The wedge shape is such that the tops of the side inserts 25 and of the center insert 27 extend horizontally. Gaskets 29 are present between the side jambs 9 and the side inserts 25.
Figure 3 shows the sill 5 with wing insert 23 and the central and side inserts 25 and 27 and gaskets 29 in an exploded view. Channels 31 are present in the side inserts 25 and holes 32 are present in the gaskets 29 for draining rainwater seeping into the side inserts. To this end, an open end 31a of the channels communicates with the environment at the front of the sill 5 and another open end 31b of the channels communicates through holes 32 in the gasket 29 with the space in the concave side jambs 9. In order to also be able to drain the rainwater that can seep into the frame of the fixed wing part, further channels 33 and further holes 34 are present in the central insert 27 and in the wing insert 23, via which the space in the hollow frame of the fixed wing part 13 is connected to the environment at the front of the sill 5.
For the purpose of illustration, the sill 5 and the wing insert 23 are shown separately in Figures 4 and 5. The wing insert 23 has a full-length front portion 23a and a full-length rear portion 23b. Both parts 23a and 23b are connected to each other via a poorly thermally conductive bridge piece 24, which prevents the wing insert piece 23 from forming a thermal bridge. To prevent a thermal bridge, the fixed wing part 13 is furthermore present above the front part 23a of the wing insert, so that this part is shielded.
Figure 6 shows a cross-section of a lift-slide door along line A-A in figure 1. In order to be able to easily fit the fixed wing part 13 with the attached wing insert 23 into the frame 3, the distance 35 from the edge 7a of the head jamb 7 at the bottom and at the front of the head jamb to the edge 5c of the front part 5a of the sill 5 adjacent to the rear part 5b of the sill 5 is smaller than the distance 37 from said edge 7a of head jamb 7 to an imaginary line parallel to said edge 5c of sill 5 on the front part 5a of the sill 5. As a result, the fixed wing part 13 with the wing insert 23 attached thereto can be turned (arrow 39) about said edge 7a of the head jamb 7 into and out of the frame 3.
Although the present invention is elucidated above on the basis of the given drawings, it should be noted that this invention is not limited whatsoever to the embodiments shown in the drawings. The invention also extends to all embodiments deviating from the embodiments shown in the drawings within the scope of the invention defined by the appended claims.
