Description

The present invention relates to a skylight or a window for a caravan or a mobile home, in particular to an opening mechanism for the skylight or window, which provides more comfortable operation for the user during opening and closing of the skylight or window. The opening mechanism is adaptable to any shape of window, it can be fitted into the frame of the skylight or window in a space-saving design, and it in no way restricts the field of view through the skylight or window.

There are skylights known in caravans with a glass pane or transparent plastic in the form of a hood and a push-up bar to open in the middle of the hood. The disadvantages of such a design are that the grab bar is positioned quite high, typically above the ceiling of the caravan, and since it is positioned across the skylight or window, it restricts the view and entry of light through the skylight. Furthermore, considerable strength is required to open or close such skylights.

Sliding windows require sufficient space on at least one side of the window to slide the glass pane or clear plastic aside. Such a design is also not suitable for a caravan skylight since things such as leaves or twigs can fall through the window into the interior of the caravan.

The aim of the present invention is therefore to provide an opening mechanism for a skylight or a window for a caravan or a mobile home, which does not have the disadvantages of those known in the prior art. In particular, there is a need for an opening mechanism with which the skylight or window can be opened with a swing-out movement of the glass pane or transparent plastic or the window sash of the glass pane or transparent plastic, which should be easily accessible, convenient to operate and which restricts the view or incidence of Light through the skylight or window should not be restricted.

In order to solve this problem, the present invention provides, in a first aspect, an opening mechanism for a skylight or a window of a caravan or mobile home, the skylight or window comprising a frame, a window sash and a window stay, having at least a first and a second window stay, which can hold the window sash in an open or closed position relative to the frame, whereby the window sash can be opened outwards. The opening mechanism of the present invention includes an operating member that can actuate a driving member by applying a force to the driving member, first and second racks having longitudinal axes arranged parallel to each other and simultaneously movable in opposite directions along the longitudinal axes by the driving member first power transmission member that can linearly transmit the power from the first rack to the first window stay, and a second power transmission member that can linearly transmit the power from the second rack to the second window stay. According to the present invention, the operating element can be operated from inside the caravan and is at least partially arranged within the frame together with the drive element and the first and second racks. In accordance with the present invention, at least one of the power transmission members is flexible and extends around a corner of the frame.

The interaction of the drive element, the two racks and the two power transmission elements represents a small but effective technical design that can be completely hidden in the frame of the skylight or window, which in turn can also be very small. The opening mechanism therefore in no way restricts the view or the incidence of light through the skylight or window. The sash can be opened outwards, e.g. pivotally, or can be moved outwards while still parallel to the frame. In order to operate the opening mechanism of the invention, any kind of operating means can be positioned on the surface of the frame that faces inside the caravan, so the opening mechanism is also easily accessible for smaller people. A further advantage of the opening mechanism of the present invention is that the skylight or window does not have just one or perhaps two individual opening positions, but can be continuously opened and fixed at any position up to the maximum opening.

According to a preferred embodiment of the present invention, the frame has at least four sides and the window sash can be pivoted outwards and is hinged to the frame on a side of the frame that is parallel to the axis of rotation of the window sash, the first and second window stays positioned on the sides of the frame next to the side of the frame where the window sash is hinged. In this embodiment, the skylight or window can be rotated outwards. The window sash rotates about the axis of rotation near and parallel to one side of the window sash, or rather the frame. The opposite side of the window sash, which is furthest from the frame in the open position, does not need any stays or the like, so that nothing blocks the opening.

According to a preferred embodiment of the present invention, the drive element is a gear and the racks have teeth arranged in a row along the longitudinal axes of the racks, the teeth of the first rack pointing in a direction opposite to that of the teeth of the second rack , protrude and wherein the first and second racks engage the gear from opposite sides of the gear. The power, i.e. H. the torque exerted on the toothed wheel is thus halved for both the first and the second toothed rack, as a result of which the force is in turn transmitted linearly to the window stays by means of the force transmission elements. Incorrect and uneven opening of the skylight or window can thus be avoided.

According to a preferred embodiment of the present invention, the racks are in the form of an elongate frame and the row of teeth is positioned on one of the inner longitudinal edges of the elongate frame. Overall, this configuration ensures a more stable and stiffer system, since excessive bending of the racks is prevented.

In accordance with a preferred embodiment of the present invention, both the first and second force transmission members are flexible and extend around a corner of the frame. Thus, the force can be transmitted linearly within the frame, regardless of the shape of the frame.

Preferably, the force transmission elements are in the form of bands having a length, a width and a thickness, the bands being longitudinally sufficiently rigid to transmit force from the racks to the window stays, and the bands being sufficiently flexible in the thickness direction are that they redirect the force around the corner of the frame. A very small technical configuration can be provided with such force transmission elements.

The first and second force transmission elements are preferably positioned at least partially within a guide rail of the frame. This leads to higher rigidity and accuracy of the system.

According to a preferred embodiment of the present invention, each of the first and second window stays has at least two rods, one rod being connected to one of the power transmission elements and the other rod being connected to the window sash, wherein when the force from the power transmission elements in the direction the window stay is transferred, the rods act as a lever so that the window sash is opened. This allows the opening width and the force required to open the skylight or window to be easily adjusted by appropriately selecting the length of the rods.

According to a preferred embodiment of the present invention, both the first and the second force transmission element are connected to the rod of the respective first or second window stay via a connecting element, the connecting element being attached to the rod via a pin which controls the rotational movement between the connecting element and the rod ensures. This leads to a higher stability and durability of the system. The connecting elements thereby reinforce the respective end sections of the force transmission elements for transmitting the force to the window stays.

According to a preferred embodiment of the present invention, the operating element has a third rack and a handle which is connected to the third rack, the third rack having a longitudinal axis which is arranged parallel to the longitudinal axes of the first and second rack, the Handle and the third rack are displaceable in a direction parallel to the longitudinal axis of the third rack and thereby the third rack can actuate the drive element directly or indirectly. With this sliding mechanism of the control, the position of the skylight or window can be identified merely by identifying the position of the handle, for example through the rear-view mirror of the caravan driver, without seeing the skylight or window itself. Furthermore, opening at predetermined opening positions can be easily realized by making appropriate markings on the sliding path of the handle.

More preferably, the control may be held in position by means of a locking device comprising a notched bar and a stop, the notched bar having a plurality of notches and being fixed in position with respect to the frame and the stop on attached to the handle, the stop being engageable with at least one of the plurality of notches by manipulating the handle to hold the position of the control, and the stop being disengageable from at least one of the plurality of notches by manipulating the handle, to change the position of the control. The open position of the skylight or window can thus be easily changed and will hold securely when the stop rests in the notched bar.

Even more preferably, the operating member has a second gear and the third rack has teeth arranged in a row along the longitudinal axis of the third rack, the teeth of the third rack meshing with the second gear and the second gear for direct actuation of the drive element is formed. The gear wheel ensures reliable power transmission.

Even more preferably, the drive member is a gear and meshes with the second gear. Thereby, the transmission ratio can be designed according to the desired opening width of the skylight or window and the desired length of the sliding path of the handle. As is known in the art, the transmission ratio can be adjusted by selecting appropriate dimensions of the interacting gears.

Preferably the third rack is in the form of an elongate frame and the row of teeth is positioned on one of the inner longitudinal edges of the elongate frame. As for the first and second racks of the present invention, this rack design provides high rigidity and accuracy in operation.

According to another preferred embodiment of the present invention, the operating element is a crank, which is designed to actuate the drive element.

According to another preferred embodiment of the present invention, the operating element is an electromechanical device that is designed to actuate the drive element.

In a second aspect, the present invention provides a skylight or window of a caravan or mobile home with a frame, a window sash, window stops, having at least a first and a second window stop, which can hold the window sash in an open or closed position relative to the frame , and the opening mechanism according to the present invention.

The present invention relates to skylights and windows of a caravan or mobile home. Thus, unless explicitly stated otherwise or where the context technically conflicts, whenever a skylight is referred to, the same applies to a window, and whenever a caravan is referred to, the same applies to a camper van.

The term "window sash" in connection with the present invention can also be referred to as a "sash". The sash is an integral component of the skylight or window, consisting essentially of the glass pane or transparent plastic of the skylight or window and may also have a frame comprising the glass pane or plastic.

The window stay according to the invention can be any means suitable for opening and closing the window sash and holding it in a desired position, typically comprising brackets or rods coupled to the window sash.

The frame of the skylight or window can have a polygonal, preferably rectangular, shape. A "side" of the frame in connection with the present invention means one of the edges of the polygon. However, the frame or the entire skylight or window can also have a round shape, at least in part. It is therefore also covered by the present invention that the portion of the frame in which the first and second racks are positioned has a round shape. In such an embodiment, the racks are bent according to the curvature of the respective frame section. Consequently, the longitudinal axes of the racks according to the present invention are not necessarily straight, but may also have a curvature. However, such curvature, if any, must be substantially constant so that the racks are simultaneously movable in opposite directions along the longitudinal axes of the drive member without abutting one another. The same logic applies to the term "parallel": two bends are parallel to each other if the distance between the bends is constant.

Force as used herein, unless explicitly defined otherwise, refers to the force required to move the first and second Rack or to open or close the skylight or window is necessary.

In the embodiments where the racks are in the form of an elongate frame, this is to be understood as a longitudinal plate-like component with a longitudinal recess across the center of the plate. The teeth of these racks are arranged in the recesses, namely on one of the longitudinal edges of the recess, and the tooth tips point to the opposite longitudinal edge of the recess.

In the 1 and 2 1, a rectangular skylight 1 is shown having a frame 10 and a sash 20 held in position by first and second window stays 140,190. In this embodiment, the window sash 20 essentially consists of a transparent plastic which is bent down at the edges so that it has a convex side and a concave side. A thin frame is positioned within the concave side of the window sash 20 wherein a track is provided for each of the window stays 140,190. Furthermore, the window sash 20 is hung on a side 12 of the frame 10 (hinge not shown). The shape of the skylight is not particularly limited. It can also be polygonal with three edges or more and with angles other than 90° between them.

The material of the glass pane or transparent plastic is not particularly limited and any suitable materials known in the art can be used. Polycarbonate and polyacrylonitrile are particularly preferred.

As in the 1 and 2 As can be seen, the sliding handle 101 of the operating element 100 is positioned on the inside of the frame 10 so that the user can easily reach it.

As also in 2 is specified, according to an embodiment of the present invention, the skylight 1 also has a pull-out fly screen and/or a pull-out blackout blind. With the opening mechanism of the present invention, the skylight 1 can be opened or closed while the screen is pulled out. This is not possible with prior art skylights with a handle bar in the glass dome.

According to a preferred embodiment of the present invention and as in 3 As shown, the drive member 115 is a gear 115 that converts its torque into a linear force for the first and second racks 120,170. The racks 120, 170 are further connected to the first and second force transmission members 130, 180, respectively, which further transmits the linear force around the corners 15 of the frame 10, or rather around the corner radii of the frame 10. As shown, the power transmission members 130, 180 are in the form of ribbons having a length, a width and a thickness and are bent around the corner radii 15 of the frame 10 in the thickness direction of the ribbons. the power is transmitted in the longitudinal direction of the tapes. The material of the force transmission members 130, 180 is not particularly limited as long as it meets the functional requirements, ie, effectively transmits the force around the corner to the window stays 140, 190 to open or close the window sash 20. Therefore, the force transmission elements 130, 180 must be sufficiently flexible in their thickness direction. Suitable plastic materials are known and can be selected accordingly according to the detailed technical design. The same applies to the thickness and width dimensions, which can be selected in such a way that both a direct and rigid transmission of force to the window stays 140, 190 and a deflection of the force around the corner radius 15 of the frame 10 are ensured.

As in the 4 and 5 As shown, the ends of the power transmission members 130, 180 are connected to the window stays (only 140 is shown), specifically to a rod 141 of the window stays. When the force is exerted on the rod 141, it pushes the second rod 142 upwards, which in turn opens the skylight 1 with a rotating movement of the window sash 20. Since the force transmission elements 130, 180 are made of a rather flexible material, the ends of the force transmission elements 130, 180 are protected with a connecting element 132, which provides more stability. Since the force is transmitted to the window stays 140, 190 by rather small pins 131 in this embodiment, the connecting member, which is preferably a stiffer and harder material than that of the force transmitting members 130, 180, also increases the durability of the mechanism.

As in 6 As shown, the drive member 115 is preferably a gear 115 which meshes with the teeth 121 of the first 120 and second rack 170 (not shown). As a result, the gear wheel 115 protrudes in its axis of rotation into the longitudinal recess of the toothed rack 120, with the row 123 of teeth 121 being arranged on one of the longitudinal edges 124 of the recess or on one of the longitudinal inner edges 124 of the frame 122. While, when looking at 6 , gear 115 is rotated clockwise, rack 120 moves to the left as row 123 of teeth 121 engages gear 115 from below. The number of teeth and their dimensions, whether on the gear 115 or on the racks 120, 170, are not particularly limited and can be designed according to practical circumstances and requirements.

The kind of the operating member 100 used for the opening mechanism of the present invention is not particularly limited. Preferred controls 100 include sliders, rods, cranks, and electromechanical devices. The operating element 100 actuates the drive element 115 and can preferably be operated manually from inside the caravan. More preferably, a handle 101 for operating the operating element 100 is arranged on a side 11 of the frame 10 facing the inside of the caravan. However, in the case of an electromechanical device, the handle 101 may merely be a switch, which in turn may be placed anywhere in the caravan and/or carried on a key ring, thus sending a signal by radio link or infrared or the like to the part of the electromechanical device that controls the Drive element 115 operated, can be transmitted.

The most preferred operating element 100 is a slider, as exemplified in FIG 7 shown. Therein a manually operable handle 101 positioned on the inside of a side 11 of the frame 10 is connected upwards to a third rack 102 which in turn can be directly engaged with the drive member 115. The handle and the third rack are slidable in directions parallel to the longitudinal axis of the third rack. As already implied by the term "rack", the third rack and the first and second racks 120, 170 are generally oblong in shape with a longitudinal axis in the direction of the rack. Furthermore, the longitudinal axes of the first 120, the second 170 and the third toothed rack 102 are parallel to one another in the sense explained above. Not necessarily, but preferably and by way of example in 7 As shown, the third rack 102 is in the form of an elongated frame 110, similar to the preferred embodiments of the first and second racks 120, 170 described above . The tooth tips of the teeth 103 point to the respective opposite inner longitudinal edge of the frame 110.

Furthermore, in 7 the operating element 100 has a locking device 109 for holding the position of the slider. The locking device 109 has a notched bar 104 whose position relative to the frame 10 is fixed. The connection between the handle 101 and the third rack 102 is resiliently mounted so that the handle 101 can be moved up and down, or rather perpendicular to the allowed direction of movement of the third rack 102. With this additional degree of translational freedom of handle 101, a stop 106 can engage and disengage notches 105 of notched rod 104. The stop 106 is thereby fixed in its position in relation to the handle 101 . As exemplified in 7 As shown, the notched bar 104 with its notches 105 points upwards toward the third rack 102. The handle 101 is below the notched bar 104 and the connection between the handle and the third rack 102 is through a longitudinal recess of the notched bar 104 The handle 101 fixedly attached to the stop 106 rests in one or more of the notches 105 from above the notched bar 104. In the embodiment shown, the stop 106 is in the shape of a T-bar which rests in a notch 105 and in this position of a spring 107 is held. To operate the operating element 100, the handle 101 can be pushed upwards together with the stop 106, so that the stop 106 disengages from the notch 105 in which it rests, and then the handle can be used in the manner described above to operate the Drive element 115 are pushed into a certain position. When the desired position is reached, the handle 101 is released and the spring 107 pushes the stop 106 down so that it rests in another notch 105. Pushing upwards deforms the spring 107 and thus a corresponding force equal to the force holding the stop 106 in the notch 105 must be applied. However, the use of a spring 107 is not mandatory. Any means that provides the desired function, such as an elastic band or the like, can be used. Most preferred, however, is a coil spring.

It is apparent that the arrangement described in connection with 7 refers to a skylight 1 as an example, but can easily be transferred to a window on a vertical side of the caravan by rotating the complete construction by 90°. The same applies to several paragraphs of the disclosure, however, for the sake of brevity, this reference is not repeated in each of them.

The drive element 115 is preferably a toothed wheel 115 which can be driven either directly or indirectly via the teeth 103 of the third toothed rack 102 . If the gear wheel 115 is driven directly by the third toothed rack 102 , the gear wheel 115 meshes with the teeth 103 . In this case, the path of movement of the handle 101 corresponds to that of the first and second rack 120, 170, the path of movement of the first and second rack 120, 170 being determined by the opening path of the window sash 20. According to a preferred embodiment, the movement path of the handle 101 can be selected independently of the opening path of the window sash 20. It can be comparatively longer in order to reduce the force necessary to move the handle 101, but it can also be made shorter if, for example, the space on the side 11 of the frame 10 is limited. To this end, an additional gear wheel 108 can be used which cooperates with the drive gear wheel 115 as a gear train, the operation of which is well known in the art and is therefore not explained in detail here. In this embodiment, the additional gear 108 meshes with the teeth 103 of the third rack 102 and with the gear 115, which is the drive element 115. In order to reduce the force required to move the handle 101, the additional gear 108 preferably has a smaller radius of the pitch circle than the gear 115. This is exemplified in FIG 8th shown. There, the third rack 102 is moved to the right, inducing counterclockwise rotation of the gear 108 as the teeth 103 engage the gear 108 from underneath the gear 108 . Counterclockwise rotation of gear 108 also induces clockwise rotation of gear 115 . As in the 9 and 10 As shown, this movement continues through movement of the first rack 120 to the left and movement of the second rack 170 to the right. An overview of the entire system of an exemplary and preferred embodiment of the opening mechanism of the present invention, which cooperates with the first and second window stays 140, 190, is in FIG 11 shown. There, the force transmission elements 130, 180 are in the form of bands which are bent around the corner radii 15 of the frame 10 and guided in guide rails 116.

Preferably, the sash 20 can be pivoted open with the opening mechanism of the present invention. However, it is also possible for the sash 20 to be moved outward while still being parallel to the frame 10. In order to achieve this, two further window checks can be provided, for example, a total of two window checks in a row on each side 13, 14 of the frame. Each power transmission element 130, 180 is then sequentially connected to two window stays. Thus, the four window stays can be moved simultaneously to open, which in turn opens the skylight 1 with a parallel movement of the window sash 20.

The handle 101 of the operating element 100 can be arranged on the surface of the frame 10 facing inside the caravan, in other words on the front side of the frame 10, as described above and for example in FIG 2 shown. In such embodiments, which also have the locking device 109, as described above and for example in 7 shown, the handle 101 is pushed towards the roof or the side wall of the caravan, in Depending on whether it is a skylight 1 or a window. In another inside 12 However, in the embodiment shown, the handle 101 may be located on the non-front side 11 of the frame 10 and, if a locking device 109 is included, pressed against the frame 10 in a direction parallel to the roof or side wall of the caravan to unlock the locking device 109. While being held down, the handle or slider 101 can be moved along the side 11 of the frame to open or close the skylight 1 or window. A further development of this embodiment is a handle 101, referred to as a pusher 101, but which operates electromechanically. Thus, when the spool 101 is moved in one direction, an electrical signal is generated which actuates the drive member 115 .

According to another in 13 In the embodiment shown, the handle is formed as a lever which is arranged on the side 11 of the frame 10 other than the front. The dashed line represents the position of the lever 101 when the opening mechanism is locked. The lever can be pivoted about an axis of rotation and will automatically rest in its folded position (solid line), such as by means similar to the locking device 109 described above. Then the lever 101 acts as a slider and can slide along the side 11 of the frame 10 be moved in the slider guide 119, as indicated by the two parallel arrows in 13 specified. Once the desired position is reached, the lever 101 can be unlocked again by pushing sideways in the direction of the axis of rotation, as indicated by the bold arrow in 13 shown, and the lever 101 can pivot back to its previous position to lock the opening mechanism.

Advantageously, on the handle 101 or lever 101 itself or in the vicinity of the handle 101 or lever 101 there are markings 118 which provide the operator with information on where to move the handle 101 or lever 101 in order to close the skylight 1 or window open or close, such as in 12 shown.

The handle or lever 101, in whatever form it takes, is advantageously provided with suitable ergonomic grooves or indentations, such as finger grooves, as for example in 12 shown.

All embodiments of the present invention preferably have additional locking means (not shown in the figures) for firmly locking the skylight 1 or window in its closed position. This is important for safety reasons, so that, for example, when driving, the skylight cannot be opened by an air flow. Such locking means are well known in the art, however, according to a preferred embodiment, the opening mechanism of the present invention also controls such locking means.
