Description

Roof window

Technical Field

The utility model relates to a roof window, this roof window includes: a frame having a plurality of frame members including a top member, two side members, and a bottom member; a sash having a plurality of sash members including a top member, two side members, and a bottom member; and an operating device comprising a handle rotatably connected to the sash member and comprising a shaft received in an aperture in the sash member, the shaft having a predetermined length and at least one cross-sectional dimension, a grip, and a pawl interacting with a striker plate connected to the frame member.

Background

There are many types and models of roof windows. Generally, windows are generally equipped with an operating device as well as a ventilation device. Some roof windows are provided with a ventilation board rotatably connected to the sash, which ventilation board fulfils the function of the operating means simultaneously for releasing and actuating the lock cooperating with the frame.

Solutions with pivotally connected ventilation boards have proven to function particularly well, as described for example in the applicant's european patent No. ep 2751355B 1.

However, in some roof windows it is desirable to provide the roof window with a simpler ventilation device and to separate the opening operation of the window from the ventilation device. While this provides many advantages including less complex design and manufacture, the sash member housing the handle shaft is more exposed to external loads not only during normal operation involving handle operation, but also in the event of excessive loads and sudden impacts, for example caused by a person inadvertently stepping on the sash during installation or maintenance, snow or wind loads, or attempts to break and enter, for example. This in turn may lead to damage of the components, in particular of the sash.

SUMMERY OF THE UTILITY MODEL

It is therefore an object of the present invention to provide a roof window which reduces the risk of potential damage in a simple manner.

This is achieved by the roof window mentioned in the introduction, which is further characterized in that the handle is connected to the sash bottom member and is provided with a damping sleeve having a predetermined length, at least one outer cross-sectional dimension and an opening having at least one cross-sectional dimension, and the damping sleeve extends around the shaft.

In this way, a suitable compromise has been found to place the handle in an easy-to-reach position and to achieve the aim of increasing simplicity, while a mechanically reliable and cost-effective solution has been found in a damping sleeve which acts as an additional fixing element and absorbs any impacts from affecting the roof window, which impacts might otherwise damage the sash bottom member, in particular the interior of the sash bottom member.

The presently preferred embodiments and other advantages will become apparent from the following detailed description and the accompanying drawings.

Detailed Description

Referring first to fig. 1, the general configuration of a roof window is shown.

The roof window here comprises a main frame in the form of a fixed frame 1, the fixed frame 1 being configured for mounting in an inclined roof surface, where the fixed frame 1 is mounted in the inclined roof surface by means of mounting brackets 3 provided at the corners, but other mounting principles may also be applied. The frame 1 comprises a plurality of frame members, here comprising a frame top member 11, two

frame side members

12 and 13, and a frame bottom member 14.

To the fixed frame 1 at least one sub-frame is connected, which in an embodiment is shown as a sash 2 carrying a pane 4. The sash 2 is pivotally connected to the fixed frame 2 so as to enable rotation of the sash 2 to an open position. For this purpose the sash 2 is provided with a hinge fitting part (not shown) which cooperates with a counterpart hinge fitting part (not shown) provided on the frame 1. Corresponding to the frame 1, the sash 2 comprises a sash top member 21, two

sash side members

22 and 23, and a sash bottom member 24. In principle, the hinge axis may be positioned arbitrarily in the roof window, but here the hinge axis is substantially centrally hinged. The roof window may also be top hinged, which means that the hinge axis is located near the frame top member 11 and the sash top member 21.

From the closed position shown, the user operates operating means of the window, here in the form of a handle 5 at the bottom member 24 of the sash 2, the handle 5 interacting with a striking plate 8 fastened to the bottom member 14 of the frame 1.

Finally, the roof window is provided with a ventilation device 6 accommodated in the top sash unit 7, the ventilation device 6 being adapted to allow air to pass also in the closed position of the window. Further details of the ventilation device 6 and the top sash unit 7 are the subject of a co-pending patent application of the applicant having the same filing date as the present application and the content of which is incorporated herein by reference.

The following description of embodiments of the roof window will focus in particular on the handle 5.

As mentioned, the operating means for opening and closing the sash 2 relative to the frame 1 comprises a handle 5, which handle 5 is rotatably connected to the sash bottom member 24. The handle 5 includes a shaft 55, the shaft 55 having a predetermined length Ls and at least one cross-sectional dimension Hs. The shaft 55 may in principle have a variety of cross-sectional configurations, including, for example, triangular or hexagonal, but in the illustrated embodiment the shaft 55 has a generally square cross-sectional configuration and the at least one cross-sectional dimension Hs is a side of a square. As best shown and illustrated in fig. 4, the shaft 55 is provided with a chamfered edge here.

The shaft 55 is received in an aperture 245 in the sash bottom member 24 and the shaft 55 has a grip 51 for a user to grip and a pin or pawl 56 for interacting with the striker plate 8 connected to the frame bottom member 14. Other components of handle 5 include a crank portion 52, a console (console) 53 and a washer 54. For fastening the handle 5 to the sash bottom member 24, an aperture 246 is provided for receiving fastening means, such as a bolt, in the mounted state in a movable part (not shown in detail) of the console 53.

During manufacture of the roof window, the damping sleeve 9 is positioned on the shaft 55 to extend around the shaft 55, such that the sleeve 9 at least partially encloses the shaft 55, and the handle 5 with the sleeve 9 is connected to the sash bottom member 24.

The sleeve 9 has a predetermined length L, at least one outer cross-sectional dimension D and an opening 92 having at least one cross-sectional dimension H. Referring to fig. 7, the opening 92 in the sleeve 9 has a generally square configuration in the illustrated embodiment, and the at least one cross-sectional dimension H is a side of the square. Rounded edges are provided at the corners of the square opening 92. Here, the sleeve 9 has a substantially cylindrical cross-sectional configuration, and the at least one outer cross-sectional dimension is the diameter D of the sleeve 9.

Preferably, the predetermined length L of the sleeve 9 is selected such that the sleeve 9 extends around a major part of the length Ls of the shaft 55, preferably at least over 60% of the length Ls of the shaft 55.

In the shown embodiment the free portion 55a of the shaft 55 is substantially entirely accommodated within the sash bottom member 24, and here the sleeve 9 extends around the shaft 55 over substantially the entire free portion 55a of the length Ls of the shaft 55. This in turn means that the entire length of the shaft 5 within the sash bottom member 24 is covered.

To retain the sleeve 9 on the shaft 55 of the handle, it is preferred that the cross-sectional dimension H of the opening 92 in the sleeve 9 substantially corresponds to the cross-sectional dimension Hs of the shaft 55, such that an interference fit is provided between the sleeve 9 and the shaft 55.

Correspondingly, the aperture 245 in the sash bottom member 24 has a substantially cylindrical shape and an inner diameter substantially corresponding to the diameter D of the sleeve 9.

The wall thickness of the sleeve 9 should be chosen such that satisfactory damping properties can be obtained, while sufficient wear resistance can be obtained. Measured as the ratio between the diameter D of the sleeve 9 and the side H of the square of the sleeve 9 of the shown embodiment, it is preferred that the ratio is in the range of 0.2 to 0.65, preferably in the range of 0.4 to 0.6, more preferably in the range of 0.55 to 0.59. Suitable dimensions for the sleeve 9 are selected according to physical requirements and materials, but in a typical example the diameter D is in the range 10mm to 20mm and the sides H of the square are in the range 5mm to 10 mm. Here, H is about 8.3mm and D is about 14.2mm, so the ratio is about 0.58.

The length L of the sleeve 9 is selected according to the sash part, but the length L of the sleeve 9 is typically in the range of 30mm to 60mm, preferably 40mm to 50 mm. Here, L is about 44 mm.

In principle, the sleeve 9 may be made of any suitable material that meets the requirements for damping properties and wear resistance, but is advantageously made of a plastic material, such as a thermoplastic elastomer TPE. The material can be easily and cost-effectively provided as a molded part, for example by extrusion or injection molding.

The configuration of the frame 1 and sash 2 may in principle be a compact wooden construction; however, in the embodiment shown, at least the sash bottom member 24 is provided as a molded part comprising a housing 240 of a plastic material, such as polyurethane PU, the housing 240 enclosing a set of

core members

241, 242, 243, and wherein the core member, here denoted as the first core member 241, accommodating the shaft 55 of the handle 5 is made of a relatively stronger material than the other core members of the set, here the second core member 242 and the third core member 243. Also visible in fig. 6 is the configuration of the recess 249 and the frame bottom member 14, the recess 249 being used for manufacturing purposes, the configuration of the frame bottom member 14 including the housing 140, the first core member 141 and the second core member 142.

Finally, the impact panel 8 in the frame bottom member 14 includes: a locking recess 81, the locking recess 81 corresponding to a closed position of the sash 2 with respect to the frame 1; and a vent recess 82, the vent recess 82 allowing a slightly open position. The impact panel 8 is made of a plastic material reinforced by glass fibers. Furthermore, apertures 83 for fastening means such as screws are shown.

The present invention is not limited to the embodiments shown and described above, but various modifications and combinations may be made.
