Description

Technical Field

[0001] The present invention relates to an angular bearing for windows, doors or the like, having a base plate and a connecting device, the base plate being designed for fastening in a corner of a window frame of a window, door or the like formed of converging C-shaped profile elements, the connecting device being connected to the base plate and being connectable to a sash of the window, door or the like to movably mount the sash onto the window frame. Background Technology

[0002] These angular bearings typically form components of rotating fittings, tilting fittings, or rotating-tilting fittings. Depending on the design, angular bearings can be provided for fastening to the lower or upper corners of the window frame. The angular bearings are usually concealed, meaning they are entirely disposed between the window frame and the sash frame. Although the angular bearings are internally arranged, to avoid collisions between the window frame and the sash when the sash is opened by rotating it, the connecting device can be designed so that the sash performs a parking movement transverse to the plane of the window frame when opened. For this purpose, the connecting device may specifically include an unfolding arm and a control arm, which are interconnected to form an X-shaped scissor. The connecting device may also include a scissor arm for steering the tilting fitting, or be designed for attachment to such a scissor arm. In this respect, the angular bearings of the above type can also form scissor bearings.

[0003] Especially due to the increased weight of the sash, reliable fastening of the base plate to the window frame is crucial. In principle, the base plate can be screwed onto the window frame. Alternatively, flat-head screws oriented at an angle to the window frame plane can be used to clamp the base plate onto the C-shaped profile element. However, there is a problem with the screws screwed into the profile element, which often leads to corrosion, as the screws are typically designed as steel screws while the profile element is designed as an aluminum component. Furthermore, the different components have different coefficients of thermal expansion due to their different materials, so the angular bearings may loosen due to tension differences when heated or cooled. Summary of the Invention

[0004] The purpose of this invention is to design an angle bearing of the type described at the beginning, so that the base plate can be reliably fastened to the window frame without the risk of angle bearing corrosion or loosening.

[0005] The objective is achieved by an angular bearing according to one aspect of the invention.

[0006] The angular bearing according to the invention includes an angular support having a first clamping leg and a second clamping leg, the first clamping leg extending in a first longitudinal direction for securing a base plate to a horizontal C-shaped profile element of a window frame, and the second clamping leg angled relative to the first clamping leg and extending in a second longitudinal direction for securing the base plate to a vertical C-shaped profile element of the window frame, wherein the first clamping leg of the angular support is arranged on the back of the base plate opposite to the connecting device and is rotatably mounted about a rotation axis between an insertion position and a clamping position, wherein in the insertion position the first clamping leg can be inserted into a groove of the horizontal C-shaped profile element, and in the clamping position the first clamping leg engages with the rear of the web of the horizontal C-shaped profile element, wherein the first clamping leg can be pulled toward the base plate in a circumferential direction of rotation by an adjusting device so as to clamp the base plate onto the window frame in the clamping position of the first clamping leg.

[0007] Compared to clamping plates, blocks, or discs that clamp individually or more precisely, one by one, the slender clamping legs of the angle bracket allow for clamping or supporting a larger surface area. Due to the two angled clamping legs, the base plate can be secured or at least supported on both the horizontal and vertical profile elements.

[0008] If the first clamping leg is in the insertion position, it can be oriented parallel to the longitudinal extension of the groove and inserted without the need for cumbersome threading. The first clamping leg is then rotated to the clamping position, causing the sections of the first clamping leg on either side of the axis of rotation to pivot in opposite directions, such that the two opposing webs of the horizontal C-shaped profile element engage the rear of these sections respectively. In this way, the first clamping leg can be laterally tensioned into the profile groove. This ensures that the base plate is particularly securely fastened to the profile. The first clamping leg in the clamping position can be pulled against the base plate by operating an adjustment device to clamp the web between the first clamping leg and the base plate, thereby securing the base plate to the horizontal profile element.

[0009] As the first clamping leg rotates from the insertion position to the clamping position, the second clamping leg also rotates and reaches the support position, in which the second clamping leg engages with the rear of the web of the vertical profile element along its entire length. In the support position, viewed in cross-section, the second clamping leg can be inclined relative to the transverse inner wall and / or rear inner wall of the profile groove, and thus can be supported in or tensioned within the profile groove.

[0010] Preferably, the axis of rotation extends laterally, and particularly perpendicularly, to the back side of the base plate. Therefore, when the back side of the base plate abuts against the upper or lower side of the horizontal profile element, the first clamping leg can be laterally tensioned into the horizontal C-shaped profile element.

[0011] The first clamping leg is preferably mounted on the base plate via a rotary bearing that defines a rotation axis. The rotary bearing may be designed to allow the corner support to shift relative to the base plate along the rotation axis at least in a partial area, thereby allowing the first clamping leg to be axially adjustable for clamping. The area allowing shift may be defined by a stop. The rotary bearing is preferably designed to prevent any further movement of the first clamping leg relative to the base plate other than rotation about and shifting along the rotation axis, i.e., to prevent uncontrolled swinging or slackening of the first clamping leg.

[0012] In one embodiment of the invention, the rotation axis is designed as an adjusting element of the adjusting device. This saves space.

[0013] Specifically, the rotary bearing may include a bearing screw that passes through a circular hole in the base plate and is received in a threaded hole in the first clamping leg. The first clamping leg can be axially moved by rotating the bearing screw. Furthermore, the first clamping leg can be rotated about the bearing screw by a direct or indirect mechanical load. The bearing screw preferably passes through the circular hole at least substantially without clearance to prevent the first clamping leg from wobbling.

[0014] According to an embodiment of the invention, the adjusting device includes at least one adjusting element remote from the bearing, the adjusting element being arranged at a distance from the rotary bearing relative to a first longitudinal direction. Due to the adjusting element remote from the bearing, a clamping force can be applied to the outwardly pivoting section of the first clamping leg in the clamping position. To particularly advantageously introduce force, the adjusting element remote from the bearing can be arranged in the region of the leg end of the first clamping leg.

[0015] The adjusting element, located away from the bearing, can be an adjusting screw that passes through the base plate with a radial clearance and is accommodated in a threaded hole in the first clamping leg. This achieves a particularly simple structure. Due to the radial clearance, the adjusting screw can pass through a corresponding elongated hole or a hole in the base plate larger than the diameter of the screw shank.

[0016] According to an embodiment of the invention, the base plate is provided with angled supporting legs, and the angle bearing includes an additional adjusting screw located away from the bearing. This adjusting screw passes through the angled supporting leg with a radial clearance and is received in a threaded hole in the second clamping leg. Therefore, the second clamping leg of the angle support serves both a supporting function and can be tightened for clamping and fixation. The supporting legs may, in particular, protrude from the base plate at a right angle. The adjusting screw located away from the bearing may be arranged on the free leg ends of the first and second clamping legs, respectively.

[0017] Another embodiment of the invention specifies that the adjusting screws, particularly the individual adjusting screws remote from the bearing, have countersunk heads and pass through elongated holes in the base plate, wherein a receiving section for accommodating the countersunk head is designed on the front side of the elongated hole facing the coupling device. When the adjusting screws remote from the bearing are guided through the elongated hole at a position offset from the receiving section and screwed into the first or second clamping leg, the countersunk head is supported on the edge of the elongated hole and is laterally pressed in the direction of the receiving section due to the conical shape of its deflection force. The corresponding clamping leg is pushed to one side together with the countersunk head. Therefore, when the adjusting screws remote from the bearing are screwed in, the clamping legs located in the insertion position automatically move into the clamping position, thereby simplifying the assembly of the angular bearing.

[0018] According to a specific embodiment of the invention, the first clamping leg tapers towards the end of the free leg, thereby increasing the range of motion before the outwardly pivoting end of the free leg contacts the inner wall of the groove when the first clamping leg rotates in the direction of the clamping position. This taper can be achieved by tilting the first clamping leg to one or both sides of the end of the free leg.

[0019] To enable particularly simple and low-cost manufacturing while ensuring high stability, corner brackets can be designed as one-piece metal components, especially steel plate components.

[0020] The base plate preferably extends at least along a first longitudinal direction. This means that when the first clamping leg is in the insertion position, the base plate and the first clamping leg are oriented at least substantially parallel to each other. This results in an advantageous, elongated clamping surface.

[0021] A specific embodiment of the invention specifies that the base plate has at least one positioning element projecting from its rear side, the positioning element being designed to insert into a groove in the horizontal C-shaped profile element. This simplifies the assembly of the angular bearing. The positioning element may have a width measured transversely to the first longitudinal direction, the width being adapted to the width of the groove opening, thereby preventing lateral slippage of the base plate against the horizontal profile element before final clamping.

[0022] The base plate may have at least two positioning elements spaced apart from each other relative to a first longitudinal direction, each positioning element projecting from the back of the base plate and designed for insertion into a groove of a horizontal C-shaped profile element. This ensures particularly reliable pre-fixation of the base plate to the window frame. If the base plate is provided with angled support legs, the support legs may also have protruding positioning elements designed for insertion into grooves of vertical C-shaped profile elements.

[0023] The present invention also relates to windows, doors, or the like having window frames comprising interconnected C-shaped profile elements made of metal, particularly aluminum, and sashes movably mounted on the window frame by means of at least one angular bearing arranged at a corner where the window frame is formed by two converging profile elements. According to the invention, the angular bearing is designed as described above. This type of angular bearing is particularly suitable for metal windows, metal doors, and the like.

[0024] Further embodiments of the present invention can be derived from the specification and drawings. Attached Figure Description

[0033] Figure 8This is a perspective view of an angular bearing according to a second embodiment of the present invention. Detailed Implementation

[0034] Figures 1 to 4 An angular bearing 11 according to the invention is shown, the angular bearing forming part of a rotating or tilting fitting for a window, door, or the like. The angular bearing 11 has a base plate 13 designed for fastening to a window frame 14 of the window, door, or the like, such as... Figure 4 As shown in the diagram. The window frame 14 is composed of profile elements 81 and 82, which are preferably made of metal, particularly aluminum, iron, or steel. Each of the profile elements 81 and 82 is designed with an elongated, C-shaped groove 85 having an opening 87 and two opposing webs 88 and 89. Figure 4 Only two of the at least four profile elements 81 and 82 of the window frame 14 can be seen, namely the horizontal profile element 81 and the vertical profile element 82, which converge to form the corner 90 of the window frame 14, which is the lower right corner 90.

[0035] In the illustrated embodiment, the base plate 13 extends in a first longitudinal direction 16 and is provided with a vertically projecting support leg 17 extending in a second longitudinal direction 18. When the angular bearing 11 is installed, the first longitudinal direction 16 extends horizontally, and the second longitudinal direction 18 extends vertically. The base plate 13 is preferably made of metal.

[0036] The connecting device 20 is arranged on the front side 15 of the base plate 13 and can be connected to a sash (not shown) of a window, door, or similar structure in a substantially known manner, so as to rotatably mount the sash onto the window frame 14. According to... Figures 1 to 4 In one embodiment, the connecting device 20 includes an extension arm 23 and a control arm 25, each mounted on the base plate 13 and connected to the fan via their respective connecting pins 29. The extension arm 23 and the control arm 25 are cross-connected to each other to form an X-shaped scissor.

[0037] To secure the base plate 13 to the lower right corner 90 of the window frame 14, the following is set: Figure 2 The corner support 30, shown separately, is movably mounted on the back side 33 of the base plate 13 opposite to the connecting device 20. The corner support 30 is preferably designed as a single, angled metal plate. Specifically, the corner support 30 has a first clamping leg 35 and a second clamping leg 36 angled thereto, wherein, according to… Figure 1 In the assembled state of the angular bearing 11, the first clamping leg 35 extends in the first longitudinal direction 16, and the second clamping leg 36 extends in the second longitudinal direction 18. As shown in the figure, the first clamping leg 35 and the second clamping leg 36 of the angular support 30 are plate-shaped.

[0038] like Figure 2 As shown, the first clamping leg 35 and the second clamping leg 36 are respectively provided with external threaded holes 41 and 42 in the regions of their free leg ends 37 and 39. The first clamping leg 35 is also provided with another internal threaded hole 43. This is arranged between the external threaded hole 41 of the first clamping leg 35 and the second clamping leg 36. As shown, the first clamping leg 35 has bevels 46 on both sides of its free leg end 37, and therefore gradually tapers towards the free leg end 37.

[0039] Angle support 30 is mounted on base plate 13 by bearing screws 45, which pass through a circular hole 47 formed in base plate 13 and are received in the internal threaded hole 43 of first clamping leg 35. Specifically, the bearing screw 45 guided through the circular hole 47 forms a rotary bearing 50. Figure 1 In addition to allowing the corner support 30 to rotate about the rotation axis 49, it also allows the corner support 30 to be adjusted axially along the rotation axis 49. The rotation axis 49 extends perpendicular to the first longitudinal direction 16 and perpendicular to the back surface 33 of the base plate 13. The rotation axis 49 also extends parallel to the second longitudinal direction 18. The circular hole 47 preferably adapts to the shank diameter of the bearing screw 45 so that the rotary bearing 50 has no significant radial clearance.

[0040] Adjusting screws 53 and 54, respectively, located away from the bearing, are accommodated in external threaded holes 41 and 42, passing through elongated holes 55 and 56 in the base plate 13. The elongated holes 55 and 56 allow the corner support 30 to rotate about the rotation axis 49 within a range of motion predetermined by the dimensions of the elongated holes 55 and 56. The first clamping leg 35 of the corner support 30 can be moved in the direction of the back surface 33 of the base plate 13 by screwing in the adjusting screw 53 and bearing screw 45, which are located in the external threaded hole 41 of the first clamping leg. Similarly, the second clamping leg 36 of the corner support 30 can be pulled towards the support leg 17 of the base plate 13 by screwing in the adjusting screw 54, which is located in the external threaded hole 42 of the second clamping leg 36. The elongated holes 55 and 56 also allow movement transversely to their longitudinal axes. The adjusting screws 53 and 54 and bearing screw 45 thus form an adjusting device 60 by which the corner support 30 can be pulled onto or secured to the base plate 13. As in Figure 2 As can be seen, the bearing screw 45 and the adjusting screws 53 and 54, which are far from the bearing, are designed as countersunk screws.

[0041] Three spaced-apart positioning elements 65 are arranged on the base plate 13. Two positioning elements 65 protrude from the back surface 33 of the base plate 13, while positioning element 65 protrudes from the side surface 66 of the support leg 17. The positioning elements 65 have a width of 67 (…). Figure 3 The width at least substantially corresponds to the width of the opening 87 of the standardized profile groove. For example, the width 67 of the positioning element 65 can be 10 mm. In the illustrated embodiment of the invention, the positioning element 65 is designed as a separate component riveted to the base plate 13. In principle, the positioning element 65 can also be designed integrally with the base plate 13. The corner bracket 30 covers the positioning element 65 on the back 33 of the base plate 13 or the side 66 of the support leg 17.

[0042] To secure the corner bearing 11 to the window frame 14, the base plate 13 and the corner bracket 30 are positioned in front of the corner 90 of the window frame 14. The corner bracket 30 and the positioning element 65 are inserted into the openings 87 of the grooves 85 of the horizontal profile element 81 and the vertical positioning element 82, which is facilitated by the design of the corner bracket 30 being slightly narrower than the openings 87 of the grooves 85. For example, the first clamping leg 35 and the second clamping leg 36 of the corner bracket 30 are 9.5 mm wide. The positioning element 65, abutting against the webs 88, 89, holds the base plate 13 in a defined position and prevents the base plate 13 from moving laterally in the first longitudinal direction 16.

[0043] Subsequently, the adjusting screw 53, located away from the bearing in the threaded hole 41 at the end of the first clamping leg 35, is acted in the lateral displacement direction by a tool (not shown), the lateral displacement direction being... Figure 5 The first clamping leg 35 is marked as 77 and extends laterally in the first longitudinal direction 16. It rotates about the rotation axis 49 in the rotation direction 78, according to... Figure 5 Clockwise. From Figure 5 Starting from the insertion position shown, the corner support 30 reaches... Figure 6 and Figure 7 The clamping position shown, wherein the free leg end 37 of the first clamping leg 35 is as follows: Figure 6 As shown, it is located below the web 88 on the left side of the figure. The portion of the first clamping leg 35 located between the rotation axis 49 and the second clamping leg 36 moves in the opposite direction to the lateral displacement direction 77 and reaches below the web 89 on the right side of the figure. The second clamping leg 36 also moves in the opposite direction to the lateral displacement direction 77, as indicated by arrow 79. When the corner support 30 is in the clamping position, the second clamping leg 36... Figure 7 The vertical profile element 82 shown is positioned slightly inclined below the web 89 of the vertical profile element 82 on the right side of the figure. Therefore, the corner support 30 is tensioned in the corner 90 of the window frame 14.

[0044] Then tighten the adjusting screws 53, 54 and bearing screw 45 away from the bearing to clamp the webs 88, 89 of the profile elements 81, 82 between the corner support 30 and the base plate 13, and fix the base plate 13 to the window frame 14.

[0045] Actuating the adjusting screw 53, which is far from the bearing, in the displacement direction 77 using a tool is not absolutely necessary. A receiving section 92 is designed on the front side of the elongated holes 55 and 56. Figure 2 The receiving portion is adapted to the countersunk head 93 of the adjusting screws 53 and 54 located away from the bearing. When the corresponding adjusting screws 53 and 54, located away from the bearing, pass through the corresponding elongated holes 55 and 56 and are screwed into the corresponding threaded holes 41 and 42 at a position offset from the receiving section 92, the countersunk head 93 is supported on the edge 94 of the elongated holes 55 and 56, and due to the conical shape pressing laterally in the direction of the receiving section 92, the corresponding clamping legs 35 and 36 also move laterally. Therefore, when one of the adjusting screws 53 and 54, located away from the bearing, is screwed in, the corner support 30 located in the insertion position automatically moves to the clamping position.

[0046] Figure 8 An alternative embodiment of the angular bearing 11' according to the invention is shown, which, like the angular bearing 11 described above, has a base plate 13 and an angular support 30. However, compared with... Figure 1 Different, according to Figure 8 The designed angular bearing 11' has an alternatively designed connecting device 20', which has a scissor arm 95 that can be connected to the sash. The angular bearing 11' thus forms a scissor bearing, which will be assembled at the upper corner of the window frame 14. Particularly advantageous is, as... Figure 1 The angular bearing 11 shown and as Figure 8 The arrangement of the angular bearings 11' shown allows the sashes to be mounted together on the window frame 14. Because the angular supports 30 are rotatable, the sashes can be installed and supported with exceptional reliability, without concern for corrosion.
