FIELD OF THE INVENTION
[0001] The invention relates to a window frame used to install a window and to a sloped
roof window according to the preambles of claims 1 and 10, respectively. Such window
frames and windows are known eg. from
WO 98/22684.
BACKGROUND OF THE INVENTION
[0002] To construct a window in a sloped roof, first need to install the frame in the roof
by means of supporters, then fit the sash with glass on the frame, with the frame
and the sash covered with a covering and a flashing part and some other necessary
parts.
[0003] The combination of the frame, the sash with other means or parts and the combination
of the frame with the sash satisfies people's normal use of the window constructed
in the sloped roof.
[0004] Apparently, all the parts of the window, especially the frame is very important,
the structure of the frame and other parts determine for the entire window the production
process, production cost, installation, connection, seal, waterproof, flashing part,
usage and maintenance and so on.
[0005] Generally, the frame and the top, bottom and outward facing side part of the sash
is covered to protect the wood material of the frame and the sash, so that the weather
for example the rain, the sun, or the blizzard does not erode the wood or other material
of the frame or sash. The sash covering comprises top covering, side covering and
bottom covering, the sash bottom covering covers the outward facing side of the bottom
part thereof. In order to cover the bottom part of the sash, the bottom covering is
exposed in the air. Particularly after the installation of the exterior vertical side
of the bottom covering on the sash, it will be easily scratched by other sharp and
hard material during transportation, installation, utilization and maintenance, or
damaged by the friction with the floor or the wall, This severely will cause the failure
of the bottom covering and reduces its life. Meanwhile it brings the inconvenience
to the utilization and maintenance, increases the production costs and consumes costs.
For example, in the
application WO99/51830 "AN OPENABLE WINDOW WITH MAIN FRAME AND SASH COVERING MEMBERS", the covering member
in its published specification is the like.
[0006] In the
application WO99/51831 "A ROOF WINDOW WITH MAIN FRAME AND SASH COVERING MEMBERS", the exterior side of the
bottom frame is covered by the frame bottom covering, the exterior side of the bottom
sash is covered by the sash bottom covering, which covers at the same time the frame
bottom covering, then the exterior cavity formed in between may produce a vertex which
prevent the frame and the sash from the interior erosion by the weather. Although
this bottom covering structure is well windproof and waterproof, its frame bottom
outward facing front surface is a complete vertical surface, refer to this vertical
surface, the sash bottom covering is being outward away from the frame bottom, also
it will produce the same damage problem of the sash bottom covering.
[0007] Besides, for the flashing part, which connects to the frame bottom covering, is entirely
constructed in the air at the outward front side of the frame bottom. With a slight
collision by the parts, it may cause the unsteadiness of the flashing part. Plus the
flashing part is usually made of light metal or complex material, the collision between
parts or heavier force tends to deform the flashing parts, thus jeopardize the usage
thereof.
[0008] Under certain circumstance, it is necessary to configure vertically several windows
in the sloped roof, this needs to connect the two vertically adjacent windows, and
then waterproof and drain the lower combination part of the upper window and the upper
combination part of the lower window. Due to the limitation of the aforesaid frame
structure, it will cause the same unreasonable waterproof and drainage in the combination
part.
[0009] Nowadays, with the development of the material technology, some high intensity, water
resistant, erosion resistant material is used on the frame and the sash, it may lead
to an increase of the material costs; the consumption needs in different areas will
vary with the weather and the environment. The change of the production will lead
to change of the window parts, increase of the production costs. To lower the costs,
improve the performance, make it more competitive, make the production of the window
frame simpler and more convenience, cut down the material cost to its maximum extent
without decreasing the technical performance, all are the real problems people longing
for solutions.
SUMMARY OF THE INVENTION
[0010] In order to overcome the disadvantage of the prior art, the purpose of the present
invention is to provide a frame structure which can well cooperate with the window
parts.
[0011] Another purpose of the present invention is to provide a frame structure, which effectively
protect the sash bottom covering.
[0012] Another purpose of the present invention is to provide a frame structure, which easily
connects the adjacent vertically lined windows.
[0013] Another purpose of the present invention is to provide a frame structure, which is
low cost, convenient made.
[0014] Another purpose of the present invention is to provide a sloped roofwindow, which
comprises a window frame according to the invention.
[0015] Therefore, the present invention provides a window frame, according to claim 1 and

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] The invention will now be explained in detail in the following with reference to
the drawings and embodiment:
[0019] Referring to Fig. 1, the window frame 100 of the patent comprises a top part 110,
a bottom part 150 and two side parts 130. The frame may be formed into a single piece
or be assembled by separate parts, which are made from various materials. For example,
the top part, bottom part and side parts are mould from aluminum alloy or plastic,
or other metal or nonmetal composite materials.
[0020] As shown in Fig. 2a, an operative surface 153 is extended from the top edge 151 of
the front surface (the outward facing exterior surface) of bottom part 150 gradually
downward to the bottom edge 152. It cooperates with a flashing part (not shown) that
is connected to the frame. The operative surface 153 can cooperate well with the window
members; in particular with the flashing part (not shown) having a curved surface,
it also provides good support and protection of the flashing part, and improves the
drainage of the window.
[0021] Figs. 2a - 2c show a part of the window frame incorporated respectively with operative
surfaces which are concave. The front surface of the bottom part 150 (the exterior
surface of the bottom 150 facing outward) in Figs. 2a-2c extends forward and gradually
downward from the top edge 151 to the front bottom edge 152 of the bottom part. Between
the top edge 151 and the bottom edge 152 of the bottom part is at least one operative
surface 153 provided for cooperating with a flashing part (not shown) connected with
the frame. The operative surface 153 can well cooperate with the corresponding window
members, especially with the flashing part to provide a good support and protection
of the flashing part, and hence an improved waterproof and drainage with the window.
[0022] This thickness determines the position of the perimeter basic edge of the frame exterior
surface.
[0023] The operative surface 153 is concave as in Figs. 2a and 2b The preferable operative
surface is such a concave one as shown in Fig. 2a, so that it can be easily installed
and cooperate with other members.
[0024] Fig. 2b shows that a cross section of the concave surface is profiled by straight
lines.
[0025] As shown in Fig. 2a, the operative surface 153 is extended from the top edge 151
of the front surface (the outward facing exterior surface) of bottom part 150 gradually
downward to the bottom edge 152. It cooperates with with the flashing part (not shown)
having a curved surface, it also provides good support and protection of the flashing
part, and improves the drainage of the window.
[0026] Fig. 2c shows that the cross section of the concave surface is curved.
[0027] The operative surface 153 of the bottom part 150 extends from the front edge 154
outwards beyond the bottom covering 450 connected with the sash 200, as shown in Fig.
5. Thus, the operative surface 153 extends from the top edge 151 to the front surface
edge 154 and outwards exceeds the exterior surface of the bottom covering 450. This
extended surface well protects the bottom covering 450, provides an expanded supporting
area for the flashing part, and facilitates the rain drainage. In Fig. 5, the sash
bottom covering 450 also covers the frame bottom covering 350.
[0028] The front surface edge 154 is the bottom edge of the operative surface 153 but it
may be also the top edge 154 of the second front surface 155 of the horizontal part.
[0029] The operative surface 153 shown in Fig. 2 is located at the bottom part of the window
frame or it may also be located at the top part of the frame, or both at the top part
and at the bottom part.
[0030] When the frame 100 is integrated by molding, there is perimeter basic edge 131 at
the exterior surface of the frame 100, as shown in Fig. 1. The position of the basic
edge 131 can be determined by the position of the top edge 151 of the operative surface
153 at the exterior surface. There is configured a slope along the basic edge 131
facing inwards at the exterior surface of the frame, as the slope 155 shown in Fig.
1, 2a, the slope 132 shown in Fig. 1, 3 and the slope 112 shown in Fig. 4., It facilitates
the demolding production of the frame.
[0031] In Fig. 1, the exterior of the frame 100 has a perimeter basic edge 131 along which
a sloped exterior surface is configured. As the exterior sloped surface 133 shown
in Fig. 1, 3, the exterior sloped surface 113 in Fig. 4. The exterior sloped surface
is at the top part 110 and the two side parts 130 of the frame at the same time in
this embodiment of the invention.
[0032] On the side part 130 in Fig. 3 and the exterior sloped surface 133, 113 of top part
110 in Fig. 4, there are formed supporters 134, 114 protruding from the slopes and
allow the frame remain erect. The supporters 134, 114 allow the finished frame to
stand upright on the floor steadily.
[0033] The supporting area of the supporters 134, 114 may be plane or line-shaped. It may
be a plane for a bigger supporting area. There are a plurality of supporters 134,
114 lined apart from each other; which facilitates the stability of the frame.
[0034] The supporters may comprise a plurality of dot-shaped, point-shaped surfaces and/or
line-shaped surfaces, as shown in Figs. 4a and 4b.
[0035] The supporters 134, 114 are at the side part 130, top part 110 respectively. In the
case of the operative surface configured at the bottom part of the frame, the preferred
way is to arrange an upright supporting pillar (not shown) at the bottom end 135 of
the two side parts, while the bottom plane of the pillar is at the level of the bottom
surface of the bottom part 150.
[0036] The interior structure of the horizontal part (including the top part and bottom
part) and side parts of the frame 100 in Fig. 6 consists of the exterior layer and
the interior layer 3, the exterior layer is the coating, and the interior layer is
wooded. The coating can give the wood a good protection. The coating consists of two
layers, one layer is PUR 1 and the other is paint 2. The paint layer 2 strengthens
and protects the coating. The thickness of the PUR is variable/various about the interior
layer 3 from thick to thin or from thin to thick.
