Description

DESCRIPTION

Support fitting for a tilting sash of a window or door

Background of the invention

The invention relates to a support fitting for a mobile, particularly tilting, sash of a window or door. The invention also relates to a window or door with such a support fitting.

The use of hardware to help open and/or close a tilting sash of a window or door is known.

Document CH 684350 A5 discloses a tilting and sliding door with extendable scissors actuated by elastic force.

From DE 103 00 655 A1 a window is known whose sash can be operated by means of a pull cable. The actuation device has a spring to apply an elastic force to the pulling cable. Document EP 0960999 A1 discloses a tilting window with a spring that can be actuated by moving an extendable arm.

From document EP 0276678 A2, a support fitting with a helical compression spring for a tilting sash has been known, which exerts a closing torque when the sash is closed and a retaining torque on the extendable arm when the sash is tilted.

DE 10 2015 000 452 A1 discloses a support fitting with a spring that helps both open and close a window.

From document DE 2357019 A1, a spiral spring is now known for supporting the opening of a skylight. DE 549635 A discloses a scissor-like support fitting with rigid scissor arms and a spring positioned around a scissor joint to support the opening of a skylight window.

Another scissor-shaped support fitting is known from DE 511 622 A, which has a shear with several turns.

DE 102012 106 191 B4 discloses a support fitting with two rigid arms connected by means of a rotation axis. To save mounting space, a spring is mounted in the direction of the axis of rotation in an intermediate space formed between the arms, the arms being spaced apart in the direction of the axis of rotation. Known support fittings have a complex structure and can only be adapted to different support functions or sash sizes to a very limited extent.

Object of the invention

On the contrary, the objective of the invention is to provide a support hardware that is both structurally simple and versatile. The object of the invention is also to provide a window or a door with such a support fitting.

Description of the invention

This objective is achieved according to the invention by means of a support fitting according to claim 1 and a window or door according to claim 7.

The subordinate claims reflect preferred developments.

The objective according to the invention is thus solved by a support fitting for a mobile, in particular at least tilting, leaf of a window or a door. The support fitting is designed as a constructive assembly that can be arranged between a sash and a fixed frame of the window or door. The support fitting has a support arm and an elastic element arranged or configured at one end of the support arm. The support arm has at least two, in particular exactly two, longitudinally extending projecting elements. The projecting elements are arranged at an angle to each other. The protruding elements are configured elongated, that is, longer than they are wide. Preferably, the projecting elements have the same maximum width. The support arm has a pivot point around which the support arm can rotate. The pivot point is preferably located between the two protruding elements. In this way, the support arm can be shaped like a boomerang.

At least two projecting elements can be rotated relative to each other, but can be rigidly fixed to each other. For example, the projecting elements may be engaged with each other, in particular at the pivot point. To adjust both protruding elements to each other and firmly join them together, a threaded connection or a quick closure may be provided. Due to the adjustability of the support arm, the support hardware can be used selectively as a support bracket. opening or closing support of one side of the sash, that is, a horizontal side of the sash (top side or bottom side) or a vertical side of the sash.

A particularly simple configuration from a construction point of view is obtained when the support arm is made in one piece.

Thanks to the specific configuration of the support arm and the spatial separation between the support arm and the elastic element, a particularly simple structurally configured support fitting is obtained, which can be easily adapted to different sash sizes or purposes of use by means of simple structural modifications.

The support fitting has a first rail. The support arm is connected to the first rail through the axis of rotation. Furthermore, a second end of the elastic element is connected to the first rail, in particular in a pivotable manner. The first rail allows both the union of the elastic element with the support arm and also the simple connection of the support fitting with the sash or the fixed frame. To ensure optimal transmission of force from the elastic element to the support arm, the support arm is preferably connected at a higher level than the elastic element to the first rail. The support arm and/or the first rail may have a pedestal, so that the support arm is simply connected to the first rail at a level higher than the elastic element.

The support arm is connected at one end to the elastic element. At the other end, the support arm is pivotally mounted on a second rail.

The second rail may be designed for attachment to the fixed frame or sash.

Preferably, the support arm and the elastic element are configured as a retrofit kit, that is, they are provided in addition to the extendable arms.

According to the invention, the support fitting has two extendable arms between the first rail and the second rail, the support arm being arranged between the extendable arms. The support arm and the elastic element can be retrofitted particularly easily if the support fitting has a third rail, on which the elastic element and the support arm are arranged. The third rail is preferably mounted on the first rail.

To simplify the assembly of the support fitting, the support arm can have a T-shaped projection in the region of its second end, which can engage behind the edges of an elongated hole in the second rail. The T-shaped boss can then be inserted into the elongated hole and rotated to mount the support hardware. This allows mounting of the support hardware without tools.

The ease of assembly and versatility of the support hardware is further increased if the elastic element is provided at the first end of the support arm via a hook connection. Particularly preferably, both the elastic element and the support arm each have a hook that engages with each other in the assembled state. The support arm hook can be designed in one piece with the support arm.

The elastic force of the elastic element can be adjusted to accommodate different sheet sizes or different sheet weights. The adjustability can be achieved in particular by an adjustability of the length of the elastic element.

The angle a between the projecting elements of the support arm, in particular essentially oriented towards the second rail, can be greater than approximately 180° to achieve a closing support by the support fitting. To achieve an opening support, the angle a can be less than approximately 180°, always using a tension spring. When a compression spring is used, the situation is obviously the reverse. If the angle a is in the range of approximately 180°, both an opening support and a closing support can be achieved at least in sections.

However, in a particularly preferred embodiment of the invention, the angle a between the projecting elements is between 0° and 165, to maintain the leaf in the position at a distance from the fixed frame by the reset force of the elastic element. . Uncontrolled tilting of the sash is prevented, for example, by wind energy, an unfavorable sash format and/or an arrangement of the glass too far outwards in the sash.

Preferably, the upper side of the support arm is specularly symmetrical with respect to the lower side of the support arm. The support arm can be mounted so that it can rotate 180° perpendicular to the axis of rotation, so that with the same components of the support fitting both a support fitting that opens to the right and a support fitting can be realized. that opens to the left. In other words, the support arm can be mounted rotated 180° around the longitudinal axis of the first rail.

The object according to the invention is further achieved by a window or a door with a fixed frame, a sash that is movable with respect to the fixed frame and a supporting fitting described here.

The window or door leaf can tilt and/or move away from the fixed frame. The leaf can then be designed so that it is movable parallel to the fixed frame. Alternatively or additionally, the sash may be configured such that it can be opened by rotation.

The first rail is preferably in the form of a sash rail that can be mounted on the sash. The second rail is preferably configured as a sliding rail that can be moved with respect to the fixed frame.

The support fitting preferably has the form of a pre-assembled construction assembly that is placed between the sash and the fixed frame and connects the sash with the fixed frame.

Preferably, the elastic element is arranged in the support fitting in such a way that when the sash is closed, the elastic element is tensioned.

Other advantages of the invention emerge from the description and the drawing.

The embodiments shown and described should not be understood as an exhaustive list, but rather are exemplary for the description of the invention.

Detailed description of the invention and drawings

Figure 1 shows a view of a door with a tilting and sliding leaf, in which a support fitting is provided between the leaf and the fixed frame.

Figure 2a shows an isometric view of the support fitting of Figure 1 in a completely open state. Figure 2b shows a side view of the support fitting of Figure 2a.

Figure 2c shows a plan view of the support fitting according to Figures 2a and 2b.

Figure 2d shows an enlarged partial view of the support fitting according to Figure 2c in the area of an elastic element and a support arm in the closed state of the support fitting.

Figure 3a shows part of the support fitting according to Figures 2a-2d in a side view, the support fitting transforming from a support fitting that opens to the right to a support fitting that opens to the left by means of a symmetrical assembly of the support arm.

Figure 3b shows a plan view of the part of the support fitting according to Figure 3a.

Figure 1 shows a door 10 with a fixed frame 12 and a leaf 14. The leaf 14 is supported at its bottom through a rolling carriage assembly 16. When the leaf 14 is separated from the fixed frame 12, it can move in the direction of an arrow 18. Arrow 18 symbolizes the opening direction. The leaf 14 according to Figure 1 is represented as a leaf that opens to the right. The movement of the leaf 14 occurs especially in parallel, separating itself from the fixed frame 12.

The running carriage assembly 16 has a first running carriage 20 and in particular a second running carriage 22. The running carriages 20, 22 circulate on a running rail 24.

The leaf 14 has a handle 26. The handle 26 can be moved to a first handle position 26a, in which the leaf 14 is in the closed position. In the closed position, the sash 14 is firmly locked in the fixed frame 12. If the handle 26 pivots to a second handle position 26b, the sash 14 can be separated from the fixed frame 12 and moved in the direction of the arrow 18. The leaf 14 is then in an open position. If, on the other hand, the handle 26 pivots from the first handle position 26a to a third handle position 26c, the leaf 14 cannot be separated from the fixed frame 12 on one side, in this case its lower side. However, the sash 14 can then be moved away from the fixed frame 12 on one side, here with its upper side, so that a user can move the sash 14 to a tilting position. The unilateral connection of the leaf 14 with the fixed frame 12, here on its upper side, is carried out by means of a support fitting 28.

Figure 2a shows the support fitting 28 in a separate position parallel to the blade 14 (see Figure 1). The support fitting 28 has two extendable arms 30a, 30b. The extendable arms 30a, 30b connect a first rail 32a with a second rail 32b. The first rail 32a can be arranged indirectly or, as in the present case, directly, on the sheet 14 (see Figure 1). The second rail 32b is in this case made in the form of a sliding rail and can be moved with respect to the fixed frame 12 (see Figure 1) in order to be able to move the leaf 14 (see Figure 1) in the direction of the arrow 18 ( see figure 1). The second rail 32b has sliders 34a, 34b made, in particular, of plastic.

On the first extendable arm 30a a control arm 36 is pivotally arranged. The control arm 36 allows the support fitting 28 to be locked in the fully open position in which the leaf 14 (see Figure 1) can be separated and moved as a whole from the fixed frame 12 (see Figure 1). In Figure 2a, the support fitting 28 is shown in a fully open position, that is, the position for sliding the blade 14 (see Figure 1). In the tilting position, the support fitting 28 opens less than in the fully open position to slide the sash 14 (see Figure 1). The support hardware 28 is not locked by the control arm 36 in the tilt position.

The second extendable arm 30b can pivot with a damping arm 38 of the support fitting 28. A damper 40 connected to the damping arm 38 cushions the opening and/or closing movement of the support fitting 28.

A support arm 42 is arranged between the extendable arms 30a, 30b.

The support arm 42 is connected to the first rail 32a pivotally about a pivot point 44. The support arm 42 is preferably held by a rivet 46.

The support arm 42 is connected with its first end 48a with an elastic element 50 and with its second end 48b with the second rail 32b. The elastic element 50 is connected to the first rail 32a, in the present case indirectly. The elastic element 50 may be arranged in a pivotable or deflectable manner with respect to the first rail 32a.

Figure 2b shows the support fitting 28 in a side view. Figure 2b illustrates that the support arm 42 and the elastic element 50 are arranged vertically between the first rail 32a and the second rail 32b.

Figure 2c shows the support fitting 28 in a plan view. In Figure 2c it can be seen that the support arm 42 has a first projecting element 52a and a second projecting element 52b. The first projecting element 52a extends between the pivot point 44 and the elastic element 50. The second element 52b extends between the pivot point 44 and a connection 54 of the support arm 42 on the second rail 32b.

Figure 2d shows a part of the plan view of the support fitting 28 according to Figure 2c, with the support fitting 28 being in a partially closed position. In Figure 2d it can be seen that the connection of the support arm 42 with the elastic element 50 is made through a hook connection 56. The connection 54 of the support arm 42 with the second rail 32b is made through a projection on T-shaped 58, which can be guided to mount the support hardware 28 through an elongated hole 60 of the second rail 32b.

The elastic force of the elastic element 50 can be adjusted by regulating the length of the elastic element 50. Both the first protruding element 52a and the second protruding element 52b extend longitudinally since the maximum width B1, B2 of the protruding element 52a, 52b is less than the length L1, L2 of the projecting element 52a, 52b.

To achieve an opening support, the projecting elements 52a, 52b have an opening angle a with respect to the pivot point 44 0° and 165°, preferably between 100° and 150°, particularly preferably between 115° and 135° . If the opening angle at > approximately 180°, in the illustrated embodiment, is configured >165°, the support fitting 28 can be used as a closing support.

The projecting elements 52a, 52b can be configured so that they can be moved relative to each other around the pivot point 44 to select the opening angle a, but can be fixed to each other. The projecting elements 52a, 52b may have serrations (not shown), for example in the area of the pivot point 44, in order to be able to fix the projecting elements 52a, 52b rigidly together. On the contrary, in the example embodiment shown, the support arm 42 is made in one piece.

Figure 3a shows a side view of a part of the support fitting 28. In Figure 3a it can be seen that the support fitting 28 has a third rail 32c. The elastic element 50 and the support arm 42 are arranged directly on the third rail, in particular in a pivotable manner. The third rail 32c thus allows essential components of the support fitting 28 to be combined in the form of a pre-assembled unit. Thanks to the third rail 32c, the support arm 42 and the elastic element 50 are arranged indirectly on the first rail 32a (see Figure 2a).

This pre-assembled unit shown in Figure 3a can be installed as a retrofit kit into an existing arrangement of the first rail 32a (see Figure 2a) and the second rail 32b (see Figure 2a). The connection with the first rail 32a (see Figure 2a) is preferably made by means of at least one screw 62a, 62b. The at least one screw 62a, 62b can be screwed into a nut 64a, 64b. At least one nut 64a, 64b, preferably two nuts 64a, 64b, can be pressed with the third rail 32c.

The third rail 32c may also be a pedestal 66. The pedestal 66 allows the support arm 42 to be positioned at half the height H of the elastic member 50. The pedestal 66 may be formed in one piece with the third rail 32c.

Figure 3b shows the support fitting 28 according to Figure 3a in a plan view. A comparison of Figure 2d with Figure 3b shows that the support arm 42 in Figure 3b is arranged mirror to the support arm 42 in Figure 2d. Starting from the support arm 42 in Figure 2d, the support arm 42 in Figure 3b is mounted so as to rotate about the longitudinal axis LA1 or LA2 of the first projecting member 52a or the second projecting member 52b. The longitudinal axes LA1 and LA2 extend perpendicular to the axis of rotation of the support arm 42 passing through the pivot point 44. In this way, the support fitting 28 according to Figure 3b can be opened to the left, while the opening fitting 28 according to figures 2a-2d is designed to open to the right.

The upper part of the T-shaped projection 58 is oriented at an angle B with respect to the longitudinal axis LA2 of the second projection element 52b, the angle p being between 70° and 110°, in particular between 80° and 100°, so especially preferred between 85° and 95°.

The invention refers, as a whole, to all the figures of the drawing, to a support fitting 28, which allows opening and/or closing in the area of one of the four sides of the leaf. The support fitting 28 has a support arm 42 angled with a pivot point 44. The support arm 42 has at least two projecting elements 52a, 52b, in particular exactly two projecting elements 52a, 52b. The pivot point 44 of the support arm 42 may be formed between the projecting members 52a, 52b. The projecting elements 52a, 52b are each longer than they are wide. The support arm 42 is connected at one end to an elastic member 50 such that rotation of the support arm 42 about the pivot point 44 causes the elastic member 50 to stretch or compress. Preferably, the support arm 42 and the elastic element 50 are rotatably arranged on a first rail 32a of the support fitting 28. The support arm 42 is pivotally arranged at the other end on a second rail 32b.

The pivot point 44 of the support arm 42 may be on a pedestal 66 of the first rail 32a. The pivot point 44 is preferably located at the middle of the height H of the elastic element 50. The support fitting 28 makes it possible to support the opening and/or closing of one leaf side in a particularly simple manner.
