[0001] Carriage arrangement for a sliding leaf of a sliding door
[0002] Description
[0003] The invention relates to a carriage arrangement for a sliding sash of a sliding door or a sliding window, with a carriage guided on a guide rail and with a stay mechanism for connecting the carriage to the sliding sash and for supporting the sliding sash in a stored position and in a closed position, with a stay arm and a control arm of the stay mechanism mounted on the stay arm, with a link in the carriage for guiding a control pin of the control arm, with a control block of the guide rail for supporting a locking pin arranged on the control arm.
[0004] Such a carriage arrangement is known, for example, from WO 2015 / 197388 A1. In this carriage arrangement, the control arm rests on a spring in the area of a pivot bearing with the extension arm in the stowed position. The spring ensures that the control pin is indirectly held in a stowed section of the link in the stowed position. The spring is visible from outside the carriage and tensions the components of the extension scissor.
[0005] Such carriage arrangements are used in today's parallel-tilt sliding windows or doors, where a very heavy sash weight must usually be supported. To move the sash, it must first be moved into the stowed position parallel to the frame. For this purpose, several projection arms are usually hinged to the sash. During the movement, it must be ensured that the projection arm is secured against pivoting back.
[0006] The invention is based on the problem of developing a carriage assembly of the type mentioned above in such a way that the extension arm is reliably secured against pivoting back in the stowed position and that tensioning of the components of the extension scissor is avoided. This problem is solved according to the invention in that the carriage has a spring-loaded locking slide, and that the locking slide is opposite the locking pin in the stowed position.
[0007] This design secures the extension arm against pivoting back near the end of the control arm facing away from the extension arm. This allows the components of the extension scissor to move freely against each other and prevents tensioning of the components. In the stowed position, the locking pin is reliably secured by the locking slider against pivoting back. Furthermore, the spring-loaded locking slider can be easily installed in an inconspicuous location on the underside of the carriage assembly.
[0008] According to another advantageous development of the invention, the position of the locking slide relative to the control block can be easily determined if the control block has a stop surface for supporting the locking slide.
[0009] According to another advantageous embodiment of the invention, direct support of the locking pin by the locking slide can be easily avoided if the control block has a pocket for receiving the locking pin and if the locking slide covers an opening in the pocket. This prevents pressure on the locking pin in the extended position of the extension arm, thus ensuring easy release from the extended position.
[0010] According to another advantageous embodiment of the invention, the locking pin can slide along particularly easily when the extension arm is moved out of the pivoted-out position if the locking slide has a ramp in the area projecting beyond the opening of the pocket. In the simplest case, the locking slide thus has a hammer-shaped head in a plan view with a straight surface for support on the stop surface and the ramp that adjoins the straight surface. According to another advantageous embodiment of the invention, the guidance of the locking slide is structurally particularly simple if the locking slide is guided for longitudinal displacement in a recess in the carriage and if the recess supports a spring element for preloading the locking slide.
[0011] According to another advantageous development of the invention, the carriage assembly has a smooth surface, unobstructed by spring elements, when the recess is closed by a slide cover connected to the carriage. This conceals the spring element and, together with the guide for the locking slide, protects it from dirt. Preferably, the slide cover has a locking connection in addition to a positive connection with the carriage.
[0012] According to another advantageous development of the invention, the carriage arrangement is particularly compact if the carriage has a carriage housing for supporting the rollers and for receiving the locking slide.
[0013] According to another advantageous development of the invention, the slide cover is arranged in line with the rollers and has a groove for accommodating a cleaning brush to further simplify the design of the carriage assembly. This design results in a particularly small number of components in the carriage assembly. The cleaning brush can preferably be easily and detachably secured in the groove.
[0014] According to another advantageous development of the invention, the carriage assembly is particularly simple in design if the locking pin is manufactured in one piece with the control pin. In the simplest case, the locking pin and control pin are concentric. This allows the components to be manufactured as a simple turned part. According to another advantageous development of the invention, the guidance of the control arm on the carriage is particularly simple in design if the control pin is attached to the control arm at one end and holds the locking pin at the other end, and if the locking pin has a larger diameter than the control pin.
[0015] According to another advantageous development of the invention, the carriage arrangement is particularly compact if the control arm has a bend near the control pin and if, in a retracted position of the extension scissors, the control arm lies above the extension arm. Furthermore, in the retracted position of the extension scissors, loads from the control arm are supported by the extension arm.
[0016] The invention permits numerous embodiments. To further clarify its basic principle, several of them are shown in the drawing and are described below. This shows in
[0017] Fig. 1 shows in perspective a part of a carriage arrangement for a sliding leaf of a sliding door,
[0018] Fig. 2 shows an enlarged view of a scissor hinged to a carriage with adjacent components of the carriage arrangement from Figure 1,
[0019] Fig. 3 shows a part of the carriage arrangement from Figure 2 in another perspective view,
[0020] Fig. 4 a sectional view through the part of the
[0021] Carriage arrangement from Figure 3 along line IV-IV,
[0022] Fig.5 a sectional view through the part of the
[0023] Carriage arrangement from Figure 3 along line VV. Figure 1 shows a sliding door with a sliding leaf 2 that can be moved relative to a frame 1 and with a carriage arrangement 3. To simplify the drawing, the frame 1 and the sliding leaf 3 are shown schematically. The frame 1 has a guide rail 4. The sliding leaf 2 can be moved from a closed position within the frame 1 to a stored position in which the plane of the sliding leaf 2 is away from the frame 1.
[0024] Figure 2 shows an enlarged view of a portion of the carriage assembly 3 from Figure 1 in an enlarged perspective view. The carriage assembly 3 has a frame-side carriage 5 guided on the guide rail 4 and a leaf-side bearing block 6. The carriage 5 and the bearing block 6 are connected to one another via a projection scissor 7. The projection scissor 7 has a projection arm 8 mounted on the bearing block 6 and in the carriage 5. A control arm 9 of the projection scissor 7 is pivotally mounted on the projection arm 8 and penetrates a guide slot 11 of the carriage 5 with a control pin 10. A control block 12 for guiding the end of the carriage 5 having the guide slot 11 is arranged on the guide rail 4. The control block 12 has two pockets 13 for a locking pin 14, shown in Figure 3, which is connected to the control pin 10.
[0025] Figure 3 shows the carriage assembly 3 from Figure 2 in a further perspective view. The locking pin 14 is located near an opening 15 of one of the pockets 13 of the control block 12 and is opposite a locking slide 16. The locking slide 16 is slidably guided below a slide cover 17 in the carriage 5. The slide cover 17 also has a groove 18 for receiving a cleaning brush 19 that slides over the guide rail 4. Figure 3 also shows that the control arm has a bend 28 so that it lies above the extension arm 9 when the sliding sash 2 is in the frame 1 position.
[0026] Figure 4 shows a sectional view through the carriage arrangement 3 from Figure 3 along the line IV-IV. Here, it can be seen that the locking slide 16 has the shape of a hammer head and is guided for longitudinal displacement in a recess 27 of the carriage 5. The locking slide 16 is preloaded by a spring element 21 against a stop surface 20 of the control block 12 and, with a ramp 22, partially covers the opening 15 of the pocket 13. With its ramp 22, the locking slide 16 is opposite the locking pin 14. The carriage 5 has a carriage housing 23 for supporting rollers 24 rolling on the guide rail 4. The rollers 24 are arranged in a row with the locking slide 16 and the cleaning brush 19 from Figure 3.
[0027] Figure 5 shows a further sectional view through the carriage arrangement 3 from Figure 3 along the line V - V in the area of the link 11 of the carriage 5. The control pin 10 is located in the position shown at the transition between a parking section 25 and a guide section 26 of the link 11.
