Description
A hatch comprising a frame and means for mounting the frame
The present invention relates to a hatch comprising a frame and means for mounting the frame in an opening in a wall, especially a wall of a boat or a nacelle of a wind turbine, said frame comprising a first portion for overlapping a first side of a rim part of the wall adjacent the opening, wherein the means for mounting the frame comprise an adjustable tensioning element.
Hatches, such as skylights, are known i.a. from boats, e.g. yachts, and from nacelles of wind turbines i.a. for providing an access hatch that should, when closed, provide a water tight closure.
A hatch or skylight of the above art is known from CN-U-201763128, which discloses a skylight with a frame having a perpendicular portion extending perpendicular to the first portion into the opening in the wall, said perpendicular portion having a free side provided with a slanted surface. The tensioning element is a wedge-shaped clamping block that is drawn by means of a screw towards the perpendicular portion into engagement with the slanted surface thereby stressing the free side and the slanted surface away from the wall and tightening the first portion against the wall. This construction avoids the need for providing holes in the rim part of the wall adjacent the opening, which are considered a drawback since leaks are prone to occur at such holes, but holes and screw heads are provided on the inner side of the frame, which is also a drawback, e.g. when the skylight provides an access hatch.
DE-A-28 09 71 1 discloses another construction of a hatch or skylight in which a frame comprises a first portion overlying a first side of a rim portion of the wall and a perpendicular portion extending into the opening perpendicularly to the first portion at a relatively large distance from the rim of the wall. A mounting element with a flange is tightened by means of a screw towards the first portion whereby the rim portion of the wall is clamped
between the first portion and the flange of the mounting element. This construction avoids screw holes through the rim portion as well as through the frame, but the large distance between the perpendicular portion of the frame and the rim part is drawback.
It is an object of the present invention to provide a hatch avoiding the above mentioned drawbacks of the prior art hatches.
This is obtained according to the invention by a hatch as mentioned by way of introduction which is characterised in that the means for mounting the frame further comprise a mounting element connectable to the frame in a fixed position, said mounting element having a second portion for overlapping a second side opposite the first side of the rim part of the wall adjacent the opening, wherein the adjustable tensioning element is engaging, in a mounted position, the second portion to stress said second portion in a direction away from said second side.
In an embodiment the frame comprises a profiled strip comprising the first portion; a perpendicular portion for extending in a mounted position into the opening, said perpendicular portion having a free side; and a hooked portion. The hooked portion provides for connecting the mounting element with the perpendicular portion of the frame in a fixed position.
In an embodiment the hooked portion is provided at the free side of the perpendicular portion.
In corresponding embodiments the mounting element is provided with a first projection for engaging with the hooked portion of the frame for connecting the mounting element with the frame.
In a further embodiment the frame comprises a groove opposite the hooked portion and the mounting element comprises a second projection for engagement with the groove. This further facilitates the connection of the mounting element with the perpendicular portion of the frame in a fixed position.
In an embodiment the second portion comprises a threaded hole and the tensioning element is a screw threaded in the threaded hole.
In another embodiment the tensioning element is a wedge element
comprising two opposite wedge surfaces.
In a further embodiment at least one of the wedge surfaces is serrated. This facilitates retaining the tensioning element or wedge element in a mounted position.
In an embodiment the second portion has a slanted surface opposite the second side. This provides for an extended surface engagement between the second portion and the wedge element.
In a further embodiment the slanted surface is serrated. This further facilitates retaining the tensioning element or wedge element in a mounted position.
In an embodiment the mounting element and the tensioning element are identical. This facilitates productions and logistics since an extra element in form of a special wedge element need not be produced and stocked.
In embodiments the mounting element and the wedge element are pieces of profiled strip material.
In the following the invention will be described in more detail by way of example with reference to the accompanying drawings, in which
Fig. 1 shows a nacelle provided with hatches in the form of skylights;
Figs. 2a to 2d show four steps of mounting a frame of a hatch in a first embodiment; and
Figs. 3a and 3b show two steps of mounting a frame of a hatch in a second embodiment.
Fig. 1 shows a nacelle 1 and a rotor 3 of a wind turbine of a type generally known per se. The nacelle 1 has a wall 5 and three skylights 7 are provided for access through openings in the wall 5. The skylights 7 or hatches each comprises a frame 9 (see Figs. 2a-2d and 3a-3b) provided by a profiled strip of material and a shutter that may be opened for access through the opening in the wall 5 and closed to provide a water tight seal of the opening in which the respective skylight 7 is mounted.
The mounting of the frame 9 according to a first embodiment of the present invention is disclosed in Figs. 2a-2d, which show a section of the frame 9 and a rim part 1 1 of the wall 5 adjacent an opening 13 in the wall, in
which the skylight is mounted. Thus Figs. 2a-2d show the profile of the frame 9. The frame 9 has a longitudinal direction perpendicular to the section shown in Figs. 2a-2d.
The frame 9 comprises a first portion 15, which is overlapping and overlaying a first, external side 17 of the rim part 1 1 , a sealing strip 19 being provided between the first portion 15 and the first side 17. The frame 9 further comprises a perpendicular portion 21 that extends through the opening 13. The perpendicular portion 21 has, in the embodiments shown, at a free side 23 a hooked portion 25 for engagement with a mounting element 27, as it will be described below. At another side of the perpendicular portion 21 opposite the hooked portion 25 a groove 29 is provided likewise for engagement with the mounting element 27.
The mounting element 27 is in the present embodiment a piece of a profiled strip and thus Figs. 2a-2d show the profile of the mounting element 27. The mounting element 27 comprises a second portion 31 for overlapping at a distance, in a mounted position of the mounting element 27, a second, internal side 33 of the rim part 1 1 . The second portion 31 has, as shown in Figs. 2b-2d, a slanted surface 35 opposite the second side 33. The mounting element 27 further comprises a first projection 37 insertable in the hooked portion 25 of the frame 9 and a second projection 39 insertable in the groove 29 of the frame 9.
The mounting element may be connected to the frame 9 in a fixed position by inserting the second projection 39 into the groove 29 as shown in Fig. 2a whereafter the mounting element 27 is rotated for the first projection 37 to be positioned directly above the hooked portion 25 and subsequently the mounting element 27 is shifted for the first projection 37 to be inserted in the hooked portion 25.
Thus the mounting element 27 is connected with the frame 9 in a fixed position in the sense that the mounting element 27 will not move relative to the frame 9 when stressed by a tensioning element later during mounting of the frame, as it will be described below.
The means for mounting the frame 9 comprise in the present
embodiment the mounting element 27 and a wedge element 41 as a tensioning element. The wedge element 41 comprises opposite wedge surfaces, namely an upper wedge surface 43 and a lower wedge surface 45.
It should be noted that herein, for simplicity of explanation, "up" and "down" refers to the position of the frame 9 in the views presented in Figs. 2a- 2d and 3a-3b. It should be understood that the frame 9 and thus the skylight might be mounted in other positions in accordance with the orientation of a wall in which the skylight might be mounted.
The slanted surface 35 of the mounting element 27 and the lower wedge surface 45 are, in the present embodiment, both serrated comprising sawtooth-shaped serrations as shown in Figs. 2a-2d.
Both the mounting element 27 and the wedge element 41 may be made of a plastic material and the upper wedge surface 43 is in the embodiment shown provided with a pattern of ridges to provide a yielding surface that will adapt to the surface of the wall 5, i.e. the surface of the second side 33 of the rim part 1 1 .
When mounting the frame 9 according to the first embodiment of the present invention the frame 9 is initially positioned in the opening 13 as indicated in Fig. 2a with the sealing strip 19 positioned between the first portion 15 and the first side 17 of the rim part 1 1 , and with the perpendicular portion 21 intending through the opening 13. Subsequently the mounting element 27 is connected to the frame 9 by inserting the second projection in the groove 29 (see Fig. 2a), rotating the mounting element 27 for the first projection 37 to be positioned above the hooked portion 25 and shifting downwards the mounting element 27 for the first projection 37 to be inserted into the hooked portion 25 and for the mounting element 27 to occupy the position shown in Fig. 2b. At this time the frame is secured, though not yet sealed, to the wall. Next the wedge element 41 is inserted between the second side 33 of the rim part 1 1 and the slanted surface 35 of the second portion 31 as shown in Fig. 2b. By applying a force as indicated by an arrow 40 the wedge element 41 is forced further in between the second side 33 of the rim part 1 1 and the slanted surface 35 of the second portion 31 thereby
forcing the frame 9 downwards, as indicated by an arrow 42, to compress the sealing strip 19 between the first portion 15 and the first side 17 of the rim part 1 1 to provide a water tight sealing between the wall 5 and the frame 9. Thus the frame is mounted.
The shape and orientation of the shown serrations of the slanted surface 35 and the lower wedge surface 45 allow the wedge element 41 to move to the right as seen in Figs 2b-2d, but restrict movement in the opposite direction. Thus the shape and orientation of the serrations allow mounting but restrict dismounting. Since the mounting element 27 and also the wedge element 41 are pieces of profiled strips, said pieces having a limited length, it is possible to dismount the frame by initially pushing the wedge element 41 in a longitudinal direction to remove the wedge element 41 from the engagement with the mounting element 27.
Though the wedge element 41 is shown to have a different profile compared to the mounting element 27 it should be noticed that the profile shown for the mounting element 27 might be used for the wedge element 41 without disturbing the suitability of the wedge element and thus the wedge element might be identical to the mounting element.
A second embodiment according to the invention is shown in Figs. 3a-3b wherein like parts are given the same or similar reference numerals as used in Figs. 2a-2d.
Figs. 3a-3b show in section the frame 9 with its perpendicular portion 21 inserted in the opening 13 in the wall 5. A mounting element 27' comprises first and second projections 37, 33 similar to the ones found on the mounting element 27 of the first em bodiment, and the mounting element 27' is connected to the frame 9 in the same way as described in relation to the mounting element 27 of the first embodiment.
The mounting element 27' also comprises a second portion 31 ' positioned similar to the second portion 31 of the first embodiment, but the second portion 31 ' of the second embodiment does not comprise a slanted surface since the mounting element 27' is not intended for cooperation with a wedge element. Instead the second portion 31 ' is traversed by a threaded
hole 47 for accommodating a screw 49, see Fig. 3b.
In this embodiment the mounting element is preferably made of metal, such as aluminium or an aluminium alloy, to provide sufficient strength for the thread of the hole 47.
A thrust pad 51 is provided at the end of the screw 49 to spare the surface of the rim part 1 1 .
When mounting the frame in accordance with this second embodiment, after the mounting element 27' is connected to the perpendicular portion 21 , the screw 49 is tightened against the second side 33 of the rim part 1 1 to compress the sealing strip 1 9, and the frame is mounted.
As indicated by a plurality of lines 33' the second embodiment is capable of mounting the frame 9 in walls 5 of a great interval of thicknesses.
Though both the first and the second embodiment utilise the same arrangement of hooked portion, groove, and first and second projections, it should be understood that a large variety of engagement means may be used for connecting the mounting element to the frame. In the embodiments shown in Figs. 2a-2d and 3a. -3b the engagement between the hooked portion and the first projection fixes the position of the mounting element by restricting downwards translational movement of the mounting element relative to the frame and the engagement between the groove and the second projection restricts rotational movement of the mounting element relative to the frame. In other embodiments e.g. the hooked portion might be positioned at an intermediate position between the free side and the opposite side of the perpendicular portion, and other surface parts of the frame and the mounting element than the groove and the second projection might provide for restricting the mounting element from rotating relative to the frame when in the mounted position. Also other hooking means than the shown hooked portion and the first projection might be used for connecting the mounting element to the frame.
Further, instead of, as the case is with the shown embodiments, dimensioning the depth of the groove to allow the second projection to be
inserted to a degree allowing the first projection to pass the hooked portion by rotation of the mounting element, the hooked portion might be recessed over a length larger than the length of the mounting element to allow the mounting element to be connected to the frame by vertically shifting the mounting element upwards for the second projection to be received in the groove and subsequently shifting the mounting element in the longitudinal direction of the frame for the first projection to be engaged with a non-recessed part of the hooked portion.
