Abstract

The unit (14) has a frame-sided load accommodating part (16) fastenable at a frame (10). The load accommodating part and a leaf-sided coupling part (18) are rotatably connected with each other by a load deflection element (20) so that a part of weight force of the leaf is transferred from the coupling part to the load accommodating part via the element in a mounted state. The load accommodating part and coupling part are fixed in a defined distance (d) to each other by the element, where the distance is changeable with rotation angle between the load accommodating part and coupling part. An independent claim is also included for a window or door comprising rotary bearings.

Description

The present invention relates to a load transfer for a wing of a window, a door or the like with a frame-mounted load-bearing member attachable to a frame and a wing-mountable wing-side coupling member connected to each other via a load transfer member.

Such load transfer is particularly used on heavy wings with weights of, for example, up to over 100 kg, to divert at least part of the weight of the wing into the frame and thereby relieve other fitting parts, such as e.g. Swivel bearing, with which the wing is rotatably mounted on the frame.

Known load transfer include a rod which is arranged in the assembled state of the load transfer with the wing closed approximately perpendicularly between a frame-side and a wing-side fitting element of the load transfer, so that vertical weight forces can be absorbed. The rod is mounted pivotably and rotatably on the two fitting elements, so that a rotary opening of the wing is not hindered by the rod.

When turning open the wing, the wing-side fitting element of the load transfer is moved out of its original position, so that the wing-side and the frame-side fitting element are no longer positioned vertically above each other, but a certain inclination of the rod is formed. For this reason, the rotation opening of the wing results in a reduction in the distance between the two Fitting elements in the vertical direction, which leads to a lowering of the wing relative to the frame during rotary opening.

Therefore, when using such a load transfer the pivot bearings must be designed in a special way to allow such a lowering of the wing. In addition, when turning the wing, the oblique rod is put back upright and accordingly raised the wing again by the amount of reduction, which is why for rotating the wing an increased muscle power must be applied by the user.

The object of the invention is to provide a load transfer of the type mentioned, which can be provided with reduced effort and allows easier rotary opening and rotary closing of a wing.

To solve this problem, a load transfer with the features of claim 1 is provided.

The load transfer comprises a frame-mounted load-bearing member attachable to a frame and a wing-mounted coupling member connected to a wing which are interconnected via a load transfer member such that in the assembled condition at least a portion of the weight of the wing is transferred from the coupling member to the load receiving member via the load transfer member is transferred, wherein the load receiving part and the coupling part are fixed by the load transfer member at a defined distance from each other and rotatably connected to each other and the distance with the angle of rotation between the load receiving part and the coupling part is variable.

In the context of the invention, therefore, a rotation between the load receiving part and the coupling part, as is done with mounted load transfer, for example, when pivoting open or close the wing, implemented in a change of a specified by the load transfer element distance between the coupling part and the load receiving part.

This change in the distance can be adjusted so that in the mounted state of the load transfer caused during rotation of the wing opening skew of the load transfer element is just compensated, so that no reduction of the distance between the load receiving part and coupling member occurs in the vertical direction. In this way it can be ensured that load receiving part and coupling part have a constant distance in the vertical direction during the rotary opening and a lowering of the wing is omitted. As a result, a facilitated rotation opening and rotation closure of the wing is guaranteed. In addition, the load transfer can be used with pivot bearings that do not allow lowering or raising the wing, and thereby achieve the load transfer in each rotational position of the wing a reliable load transfer effect.

Advantageous embodiments of the invention are described in the subclaims, the description and the drawings.

According to an advantageous embodiment, the distance between the load receiving part and the coupling part increases with an increase in the angle of rotation between the load receiving part and the coupling part and reduces the distance at a reduction of the rotation angle. The angle of rotation between the coupling part and the load receiving part can for example be set so that it is zero when mounted load transfer in the closed position of the wing, when turning open increases the wing and in the rotational opening position, for example, about 90 °. By increasing the distance with the angle of rotation, an inclination of the load transfer occurring when the angle of rotation increases can be compensated for.

Preferably, the distance between the load receiving part and the coupling part changes continuously with the angle of rotation. In this way, an inclination of the load transfer element, which varies continuously with the angle of rotation when load transfer is mounted, in each rotational position of the wing, i. also between the closed position and the rotational opening position, are compensated, so that the distance between the load receiving part and coupling part in the vertical direction for each rotation angle between the load receiving part and coupling part is substantially equal. Then an effective load transfer can be ensured in each rotational position of the sash, without this being accompanied by a lowering or raising the wing.

The load transfer according to the invention can in principle be used equally as a load support or as a load suspension. When used as a load support, the load receiving part of the mounted load transfer connected to the frame is located below the coupling part connected to the wing. When used as a load suspension, the load receiving part of the mounted load transfer is arranged above the coupling part. Also in the latter case can be just compensated by the variable distance between the coupling part and the load receiving part caused during pivotal opening of the wing inclined position of the load transfer element, so that a concomitant increase in the wing can be omitted.

According to an advantageous embodiment, the load transfer in the region of the load-receiving part and in the region of the coupling part each have a hinge portion in which a part of the load transfer is rotatably and pivotally connected to an adjacent part of the load transfer.

In this way, an arranged between the hinge portions portion of the load transfer element can be freely adjusted during rotation of the wing opening in an inclined position. At the same time, a rotational angle between the load receiving part and coupling part via the joint portions to a rotary connection portion of the load transfer can be transmitted by the non-rotatable coupling, in which, as described in more detail below, two portions of the load transfer can be rotatably connected to each other and a change in the distance between the coupling part and load receiving part with The angle of rotation can be caused.

In the joint section located in the region of the load-receiving part, for example, the load-receiving part can be connected in a rotationally fixed and pivotable manner to the load transfer element.

In the joint portion located in the region of the coupling part, e.g. a portion of the load transfer element, in particular a rod-shaped portion of the load transfer element, rotatably and pivotally connected to the coupling part.

Alternatively, in the joint section located in the region of the coupling part, a section of the load transfer element, which is for example rod-shaped, can be rotationally fixed and pivoted with an adjacent section of the load transfer element coupled to the coupling part be connected. The hinge portion then connects two portions of the load transferring member, with a portion of the load transferring member being adapted for coupling to the coupling member and the other load transferring portion being formed on the load receiving member.

According to an advantageous embodiment, at least one articulated section has a condyle, which is formed, for example, at the end of a rod-shaped section of the load-transfer element, and a joint socket receiving the condyle, with the articulated head and / or the articulated socket preferably having an angular, in particular hexagonal, cross section for non-rotatable coupling. The condyle may be formed in particular at one end of a rod-shaped portion of the load transfer element.

The load transfer is preferably designed so that when mounted load transfer of the distance measured in the vertical direction between the load receiving part and the coupling part with the wing closed and with the vane rotatably opened is substantially equal. In this case, a portion of the load transfer element in the closed position of the wing assume a first, for example, vertical, orientation and rotatably open wing a second orientation, which extends obliquely to the vertical. For this purpose, according to an advantageous embodiment, the load transfer has a closing configuration corresponding to a closed position of the blade and a rotary opening configuration corresponding to a rotary opening position of the blade, wherein in the closing configuration and in the rotary opening configuration a portion of the load transfer element has a different predetermined pivot angle and the load receiving part and the coupling part in different predetermined rotation angles to each other and wherein a distance between the load receiving part and the coupling part measured in a first direction, which corresponds to a vertical direction of the wing, in the closed configuration and in the rotational opening configuration of the load transfer is substantially equal.

According to the load receiving part and coupling part are rotatably connected to each other by the load transfer member. The load transfer can in this case have a rotary connection section, in which two sections of the load transfer are mechanically coupled to one another such that a distance of the two sections with the rotation angle between the two sections is variable. According to one embodiment, the load transfer on a rotary connection portion in which two portions of the load transfer are rotatably connected to each other and having at least two inclined surfaces which are arranged rotatable about an axis of rotation to each other, extend obliquely to the axis of rotation and at least partially abut each other. Such a connection section can be realized particularly easily.

A rotary connection portion of the load transfer can also have an external thread and an internal thread, wherein the external thread engages in the internal thread and forms a helical gear with the internal thread. By such a helical gear, a particularly effective and mechanically stable rotary coupling can be realized, in which the distance between the sections and the angle of rotation between the sections changes.

According to an advantageous embodiment, the load transfer has a rotary connection section comprising a sleeve with an internal thread and a pin with a male thread rotatably received in the sleeve, the sleeve and the pin forming a helical gear. In this case, the sleeve, in particular on the coupling part and the Pin be formed on a portion of the load transfer element. As part of the load transfer element, the pin can in particular be connected via a joint section to a further, in particular rod-shaped, section of the load transfer element.

The invention also relates to a window, a door or the like having a frame, a wing and a load transfer according to the invention, wherein the load receiving part is fixed to the frame and the coupling part is fixed to the wing. The load transfer may be formed as described above. The advantageous embodiments and advantages described above in relation to the load transfer apply accordingly.

According to an advantageous embodiment of the window, the door or the like, the load transfer is in a closed position of the wing in the closed configuration and in the rotational opening position of the wing in the rotary opening configuration.

The wing of the window, the door or the like can be rotatably mounted on the frame via one or more pivot bearings. A pivot bearing and in particular all pivot bearings of the window, the door or the like can also be easily designed so that they emanate from a substantially constant vertical position of the wing and allow for a rotary opening no significant vertical lowering or raising the wing. If load receiving part and coupling part of the load transfer in each rotational position of the wing have a substantially constant measured in the vertical direction distance, effective load transfer can be ensured in this case in any rotational position without raising or lowering of the wing must be made.

Fig. 1 to 7 show a window with a load transfer 14 according to an embodiment of the invention.

The window comprises a frame 10, a wing 12 and arranged between the frame 10 and wings 12 load transfer 14. The load transfer 14 comprises a fixed to the frame 10, frame-side load-receiving part 16 and attached to the wing 12, the wing-side coupling member 18, which a load transfer member 20 are connected to each other, so that in the mounted state at least a part of the weight of the wing 12 is transmitted from the coupling member 18 via the load transfer member 20 to the load receiving member 16 and discharged into the frame 10. Load receiving part 16 and coupling member 18 are fixed by the load transfer member 20 at a defined distance d from each other and rotatably connected to each other, wherein the distance d is variable with the angle of rotation between the load receiving part 16 and the coupling part 18.

The load transfer member 20 includes an elongated, rod-shaped portion 22 of hexagonal cross-section and a portion 24 connected thereto on which a pin 26 is formed with an external thread 28. In the region of the load-receiving part 16 and the coupling part 18, the load transfer 14 in each case has a joint section 30, 32. The hinge portion 30 in the region of the load-receiving part 16 comprises a socket formed in the load receiving part 16 34 and a joint head 36 which at one end of the rod-shaped portion 22 is formed and which is received in the socket 34. In the hinge portion 30, the load receiving part 16 and the rod-shaped portion 22 are rotatably and pivotally connected to each other. The second hinge portion 32 also connects a second end of the rod-shaped portion 22 of the load transfer member 20 to the portion 24 of the load transfer member 20 in a rotationally fixed and pivotable manner. The second hinge portion 32 has a condyle 37 of the rod-shaped portion 22 (FIG. Fig. 6 ) and a not shown joint socket of the section 24.

The hinge portions 30, 32 connect the load receiving portion 16 and the portion 24 via the rod-shaped portion 22 so that the rod-shaped portion 22 can be freely pivoted with respect to its vertical position when the window is rotatably opened or closed. At the same time via the two joint portions 30, 32, the load receiving part 16 via the rod-shaped portion 22 with the portion 24 rotatably connected so that the portion 24 always based on the coupling member 18 assumes the same rotational angle as the load receiving part 16th

In the region of the coupling part 18, the load transfer 14 has a rotary connection section 40. The rotary connecting portion 40 comprises a formed on the portion 24 pin 26 with an external thread 28 which forms a helical gear with a sleeve 44 of the coupling part 18 with an internal thread 46. Rotation of the portion 24 relative to the coupling member 18 results in mutual displacement of the portion 24 and coupling member 18 along a screw axis 42 in the direction of an arrow 43.

The rotary connecting portion 40 is formed in the present embodiment in the region of the coupling part 18 between the hinge portion 32 and the wing 12. However, within the scope of the invention, the pivot connection portion 40 may also be formed at the frame-side end of the load transfer 14 between the hinge portion 30 and the frame 10, and e.g. be formed by a sleeve of the load-receiving part 16 and a provided on a frame-side end of the load transfer member 20 pin. The rotary connection section can also be formed by two sections of the load transfer element 20 and in particular between the two hinge sections 30, 32 of the load transfer 14, e.g. approximately in the middle of the load transfer element 20, are located.

Fig. 1 to 7 show the load transfer 14 in the mounted state, in which the load receiving part 16 and the coupling part 18 are respectively fastened via screw holes 48 and corresponding screws, not shown, to the frame 10 and the wing 12, respectively. The load-receiving part 16 is located in an inner corner of the frame 10, which is formed by an inner side of a vertical spar 50 and a horizontal spar 52 of the frame 10. The coupling member 18 is fixed in a direction perpendicular to the load receiving part 16 spaced in a rabbet groove 55 on an outer side of a vertical spar 54 of the wing 12.

The window has one or more pivot bearings, not shown, with which the vertical spar 54 of the wing 12 is rotatably mounted on the vertical spar 50 of the frame 10. By pivot bearing or other fitting parts of the wing 12 is held during rotation opening in a non-tilted, vertical orientation. The pivot bearings can be easily formed so that they no lowering or raising the wing 12th allow, as such a reduction or increase due to the inventive design of the load transfer 14 can be omitted.

In the following, the mode of operation of the load transfer 14 with respect to the present exemplary embodiment will be explained. With the wing 12 closed, the load transfer member 20 is as in FIG 4 and 5 shown, oriented substantially vertically. In this case, at least part of the weight force of the wing 12 is transmitted via the coupling part 18 to the load transfer element 20 and discharged through the load transfer element 20 into the load receiving part 16 and the frame 10. When the opening of the wing 12, the coupling member 18 from its original, substantially directly above the load receiving portion 16 arranged position (see, eg Fig. 5 ), which leads to an inclination of the rod-shaped portion 22 of the load transfer member 20 (see, eg Fig. 6 ). In addition, during the rotation opening, the load receiving part 16 and the coupling part 18 are rotated relative to each other. Due to the rotationally fixed coupling of the load-receiving part 16 with the portion 22 and the portion 22 with the portion 24, this leads to a corresponding rotation of the portion 24 relative to the coupling part 18. The pitch of the external thread 28 and the internal thread 46 is chosen so that the pin 26 is unscrewed from the sleeve 44, so that the fixed by the load transfer element 20 distance d between the load receiving part 16 and coupling member 18 increases accordingly.

Like the comparison of Fig. 4 . Fig. 3 . Fig. 2 and Fig. 1 shows, the rotation angle between the load receiving part 16 and the coupling part 18 and thus also the fixed by the load transfer member 20 distance d are continuously increased during rotation of the wing opening 12. At the same time, the rotary opening of the wing 12 is a continuous pivoting of the rod-shaped portion 22 of the load transfer member 20 from its initial vertical position to an inclined position. The inclination of the portion 22 is compensated by the helical gear forming rotary connecting portion 40 so that the wing 12 is at least substantially at the same height in each rotational position. For this purpose, the pitch of the helical gear is adjusted accordingly.

In Fig. 6 is illustrated how the load transfer 14 is effective without lowering or raising the wing 12 both in the closed position and in the rotational opening position. Fig. 6 indicated by dashed lines indicated the load transfer member 20 and the coupling member 18 with the wing closed 12, in which the rod-shaped portion 22 of the load transfer member 20 is oriented approximately vertically. In the rotational opening position of the wing 12 of the rod-shaped portion 22 is inclined by the pivot angle 56 with respect to its vertical position. This leads to a reduction of the vertical distance between the wing-side and the frame-side end of the rod-shaped portion 22 by a difference distance f. At the same time, when the vane 12 is opened by the rotary connecting portion 40, the distance d between the coupling member 18 and the load receiving member 16 defined by the load transfer member 20 is increased so that the same vertical distance s between the coupling member 18 and the load receiving member 16 results in the rotational opening position, as in FIG the closed wing position.
