Description

The present invention relates to a running gear for a movable leaf of a sliding door or a sliding window that comprises a carriage movable relative to the guide rail and a scissor mechanism for connecting the carriage to this movable leaf, this scissor mechanism comprising a positioning rod and a guide rod for moving the running gear when closing movement from the moved position to the closed position, with the guide rod at one end mounted to rotate at nating rod and through the guide pin of the running mechanism, which moves in a guide connecting link running mechanism is connected to the carriage.

The publications DE 85 15 998 U1, EP 1 645 707 A1 and DE 200 12 165 U1 describe running gears for heavy moving sashes. Such running gears comprise a carriage which, via a scissor mechanism, is indirectly or directly connected to a movable leaf.

From EP 1 128 015 A2 it is known to move a sliding window leaf using a motor.

Utility model DE 20 2012 002 741 U1 discloses a running gear for a movable leaf, which comprises a tension spring in a scissor mechanism. The tension spring is configured to hold the movable sash in cooperation with the locking connection in the rearranged position.

From the utility model DE 87 07 044 U1 and from the application DE 32 34 677 A1 a running gear for a movable leaf is known, comprising a scissor mechanism with a direct guide rod.

WO 2010/079461 A2 discloses a running gear for a shear movable leaf, in which the positioning rod is provided with a central groove in which the scissor guide rod is at least partially immersed in the closed state of the running gear.

Due to this groove, the running gear can be compact. However, this groove weakens the bearing capacity of the positioning rod. The running gear can be locked in the extended position by means of a pressure spring.

From EP 0 619 410 A1 there is known an initially indicated running gear for a movable leaf, in which the guide pin on the guide bar of the scissor mechanism is non-circular.

Since the movable leaf is always better insulated and always has more glass plates, the movable leaf of a sliding door or sliding window is always heavier. To guide such movable flaps, it is therefore necessary to carry out the running gear used more stable and massive. In this case, however, the compactness and, accordingly, the size of the running gear suffers.

The objective of the invention is to create a running gear for heavy movable leaves, which is both stable and compact.

This problem is solved due to the running gear with the features of the independent claim 1 of the claims. In the dependent claims are characterized by suitable modifications of the present invention.

The problem claimed in the invention is thus solved by means of a running mechanism for a movable leaf of a sliding door or a sliding window, which comprises a carriage movable relative to the guide rail and a scissor mechanism for connecting the carriage to the movable leaf, the scissor mechanism comprising a positioning rod and a guide rod in order to move the running gear during the closing movement from the moved position to the closed position, the guide rod being installed at one end with awn rotation of the positioning rod and through the guide pin of the running mechanism guided in a guide connecting link running mechanism is connected to the carriage, wherein the guide pin at the other end of the guide rod is formed or installed with an offset to the guide rail relative to the width center of the guide rail.

Due to such a running mechanism, the movable sash can be rotated from a closed position to an advanced position. In the moved position, the movable sash can be moved parallel to the main plane of the frame of the sliding door or sliding window. For this, the indicated carriage may be provided with rollers that move in or along the guide rail. To close the sliding door or sliding window, the movable leaf moves parallel to the main plane of the frame until the scissor mechanism on the control unit abuts against the guide rail and the running gear rotates from the moved position to the closed position. This movement from the moved position to the closed position is called the closing movement, and the opposite movement from the closed position to the moved position is called the rearranging movement.

The closing movement, the rearranging movement, the closed position and the moved position in these materials refer to both the running gear and the movable leaf.

Under the guide pin according to this invention refers to the protrusion located or made on the guide rod, which moves in the guide link. The eccentric placement or execution of this guide pin makes it possible to shorten the guide rod in the longitudinal direction, and this ensures even more compact execution of the running gear. Such "eccentricity" of the guide pin is considered with respect to the middle of the width of the guide rod at its end, opposite to the center of rotation of the positioning rod.

The guide rail can be performed on the carriage. The guide pin is made or located on the guide rod, preferably without the possibility of reciprocating motion, and the carriage contains a guide link in which the guide pin moves.

The guide pin can be made integrally with the guide rod. Alternatively, the guide pin can be connected to the guide rod by riveting, welding, soldering, glued, screwed, or connected to the guide rod in some other way.

Preferably, the guide pin is not made on the guide rod, but is mounted on it. The guide rod and the eccentrically fixed guide pin can therefore, depending on the assembly, be used either for the running gear that opens to the right, or for the running gear that opens to the left. Due to this, the number of pre-stocked parts can be reduced, as a result of which storage costs can be reduced.

A mounting plate may be formed on the guide pin in order to form a very stable connection between the guide pin and the guide rod.

A guide rod is preferably provided on the upper side of the carriage. In this case, the upper side means the side of the carriage opposite to the running rollers of the carriage.

In order to fix the position of the eccentric portion of the guide pin relative to the guide rod and the guide link of the carriage, this guide pin is mounted or preferably made without the possibility of rotation.

The guide rail may be part of the running gear. In this case, the guide rail may have an upper protrusion of the guide rail, moreover, the guide rod assembly on which the guide pin is made, in separate sections, comes under the upper protrusion of the guide rail. The guide pin according to the invention thus makes it possible to partially "recess" the guide rod assembly for said upper protrusion of the guide rail, so that the guide rod does not collide with this upper protrusion of the guide rail.

In another preferred embodiment of the running gear, the guide rod is straight and / or without bending. Alternatively or in addition to this, the positioning rod can also be made straight and / or without bending. Each of these measures provides an even more compact and stable execution of the running gear, while the guide rod is preferably provided on the upper side of the carriage.

The running gear may include a guide rail and a control cracker, the guide rod for starting the closing movement is made with the possibility of abutment in this control cracker. In a preferred embodiment, therefore, not the guide pin or, accordingly, the guide sleeve located on it, but the guide rod itself is made with the possibility of abutment in the control cracker. Since high forces act on the scissor mechanism when focusing on the control cracker, it is particularly preferable that these forces are transmitted to this scissor mechanism directly through the guide rod, and not through the guide pin. Due to this, you can avoid the need to make the guide pin is especially massive, which further increases the stability and compactness of the running gear.

In the moved position, the guide pin is in the stop section of the carriage guide rail. In order to reliably hold the running gear in the moved position, the positioning rod may have a spring which, by pressure loading the guide rod, presses the guide pin into this stop portion of the guide link. The specified spring in individual sections may be adjacent to the supporting protrusion of the guide rod.

This spring in a closing movement can preferably be detached from the guide rod.

Further, the running gear can be made particularly small and compact if said spring is in the form of a leaf spring. The leaf spring may have several kinks in order to optimally adjust the spring rate of the leaf spring to the mechanical requirements of the running gear.

If the spring in separate sections is located in the groove for the spring of the positioning rod, then the running gear can be made both easy to assemble and compact.

In order to perceive the weight of a heavy movable leaf, it is especially important that the scissor positioning bar is substantially rigid to bend and twist. The positioning rod therefore preferably has a stepped recess for the guide rod only on one outer side. In the closed position, the guide rod is at least in separate sections located in this stepped recess for the guide rod. Such a stepped recess for the guide rod on the outside of the positioning rod only slightly reduces the strength of the positioning rod - unlike the central milled recess.

Both in the rearranging movement and in the closing movement, the supporting protrusion of the guide rod must pass past the carriage, in particular, past the carriage body. For a particularly compact execution of the running gear, the carriage has a bend, so that the supporting protrusion during the rearranging movement and the closing movement can pass the carriage without collisions.

The present invention also relates to a sliding door or a sliding window with a movable leaf and the above-described running gear.

Other features and advantages of the present invention will emerge from the following description of one exemplary embodiment of the present invention with reference to the drawings, which illustrate individual details, and also from the claims.

The features shown in the drawings are shown in such a way that the features of the invention can be clearly seen. Various features can be implemented both by themselves and in any combination with different variants of the present invention.

The drawings show the following:

FIG. 1a is a plan view of the running gear in front of the actually moved position;

FIG. 1b is a perspective view of the spring of the running gear of FIG. 1a;

FIG. 1c is a section along the line C-C in FIG. 1a;

FIG. 1d is a perspective view of the running gear in the closed position;

FIG. 1e is a perspective view of a guide rod and a guide rod assembly of a running gear;

FIG. 1f is a perspective view of the guide rod assembly of FIG. 1e;

FIG. 1g is a perspective view of the running gear in yet another position between the moved position and the closed position; and

FIG. 1h is a side view of the running gear of FIG. 1g.

In FIG. 1a shows a running gear 10 with a carriage 12 and a scissor 14. The scissor 14 comprises a positioning rod 16 and a guide rod 18. The positioning rod 16 has a first hinge 20 on which a movable leaf (not shown) of a sliding door or sliding window can be mounted indirectly or directly. The positioning rod 16 at the other end has a second hinge 22, through which the positioning rod 16 is rotatably mounted on the carriage 12. The third hinge 24 of the positioning rod 16 rotatably connects the guide rod 18 to the positioning rod 16. The third hinge 24 is a connection between the guide rod 18 and the positioning rod 16. At the other end of this connection, the guide rod 18 has a guide rod assembly 26. The guide pin 64 (see Fig. 1f) of the guide rod assembly 26 moves in the guide link 28 of the carriage 12.

The carriage 12 is mounted to move in the direction of the double arrow 30, i.e. parallel to the main plane of the frame or, respectively, in the main plane of the frame of the sliding door or sliding window in the guide rail 32 (see Fig. 1g).

The running gear 10 is in front of the actually moved position.

In other words, a sliding door or a sliding window in the one shown in FIG. 1a, the positions of the running gear 10 are almost completely open. To close the sliding door or sliding window, the movable leaf moves in the direction of the arrow 35. Due to this, the running gear 10, connected by means of the first hinge 20 with the movable leaf, also moves in the direction of the arrow 35.

In the embodiment shown in FIG. 1a of the position of the running gear 10, the guide pin 64 (see Fig. 1f) of the guide rod assembly 26 is located in front of the actual stop portion 54 (see Fig. 1d) of the guide link 28. To close the sliding door or sliding window in the moved position (guide pin 64 then in the stop section 54 of the guide link 28) the movable leaf moves in the direction of the arrow 35 until the guide rod 18 abuts against the control cracker 34 fixed in the guide rail 32 (see Fig. 1g). Due to such an abutment of the guide rod 18 in the control cracker 34, the guide pin 64 (see Fig. 1f) of the guide rod assembly 26 extends from the stop section of the guide link 28. In this case, further pulling of the movable sash closes the scissor mechanism 14, i.e. . pivoting movement of the positioning rod 16 in the direction of the arrow 36. In FIG. 1d shows the thus obtained closed position of the running gear 10.

In FIG. 1a it is seen that the guide rod 18 has a support protrusion 38 to which in an advanced position the spring 40 abuts in separate sections. The spring 40 is in the form of a leaf spring and presses the guide rod 18 in the moved position in the direction of arrow 42, i.e. in the longitudinal direction of the guide rod 18 to the specified stop section of the guide link 28. Due to this, the running gear 10 is securely fixed in the moved position.

The guide rod 18 has a recess 44 for the spring (see also Fig. 1d), into which the spring 40 enters in an moved position in separate sections. The guide rod 18 can thereby rotate especially far in the direction of arrow 36. Therefore, the guide rod 18 in its longitudinal direction can be made particularly short and compact. The dashed-dotted line 46 shows the fictitious outer edge of the guide rod 18 without the support protrusion 38 and without the recess 44 for the spring. As seen in FIG. 1a, such a compact device, respectively, such an embodiment of the running gear 10 can also be provided in that the spring 40 in separate sections overlaps the guide rod 18.

In FIG. 1b, spring 40 is shown in a three-dimensional image. From FIG. 1b, this spring 40 has a first bevel 47 and a second bevel 48. Due to the first bevel 47, the spring 40 can intercept the guide rod 18 without jamming the spring 40 on the guide rod 18 (cf. Fig. 1a).

In FIG. 1c shows a cross-sectional view of the running gear 10 along line C-C in FIG. 1a. In FIG. 1c, the installation of the spring 40 is visible. The spring 40 slides into the groove 50 for the spring of the positioning rod 16 in the direction of the arrow 52. The second bevel 48 thus grabs the rear portion of the positioning rod 16 so that the spring 40 is firmly held in the groove 50 for the spring.

In FIG. 1d shows the running gear 10. The running gear 10 is shown in FIG. 1d in its closed position. In FIG. 1d is seen already discussed in connection with FIG. 1a, the stop portion 54 of the guide link 28. Next, from a comparison of FIG. 1d of FIG. 1a it is seen that the guide rod 18 is at least in separate portions in the closed position (FIG. 1d) in the stepped recess 56 for the guide rod (see primarily FIG. 1a). This stepped recess 56 for the guide rod is thus located on the outer side 58 of the positioning rod 16. The positioning rod 16 is thus made free from the central milled recess for the guide rod 18, whereby this positioning rod 16 is particularly strong and bending resistant. In addition, the positioning rod 16 due to the rejection of the central milled recess is simple and economical to manufacture.

The carriage 12 comprises a housing 60 having a bend 62. Due to this bend 62, the support protrusion 38 does not collide with the carriage 12 when closing the movement of the running gear 10. As a result, the running gear 10 is particularly compact and stable.

In FIG. 1e, a guide rod 18 is shown together with a guide rod assembly 26. The compact and stable construction of the running gear 10 is further improved by the embodiment of FIG. 1e of the interaction of the guide rod 18 and the guide rod assembly 26. The guide rod assembly 26 has a guide pin 64 that moves in the guide link 28 (see Fig. 1d). This guide rod assembly 26 has a mounting portion 66 for connecting the guide pin 64 to the guide rod 18 (see Fig. 1d).

The guide pin 64 is made in the form of a body of revolution symmetrical about its longitudinal axis 68. The fixing portion 66 has a longitudinal axis 70, which is offset from the longitudinal axis 68 of the guide pin 64. Due to this, the guide pin 64 is fixed on the guide rod 18 in an eccentric manner.

The guide rod assembly 26 also includes a guide sleeve 71 for guiding the control pin 64 along the control cracker 34 (see Fig. 1a). The guide sleeve 71 is pressed onto the control pin 64 after this control pin 64 has been inserted into the guide link 28 during installation. By means of this guide sleeve 71, the travel mechanism 10 can open and close particularly stably. The vertical deflection of the guide rod 18 is prevented.

In FIG. 1f shows the guide rod assembly 26 of FIG. 1e without a guide rod 18. In FIG. 1f it can be seen that this guide rod assembly 26 in the region of its fastening portion 66 has a flattening 72 which extends into a correspondingly flattened recess of the guide rod 18 (see Fig. 1e). The node 26 of the guide rod, and thereby the guide pin 64 are installed due to this on the guide rod 18 (see Fig. 1e) without the possibility of rotation.

The guide rod assembly 26 between the guide pin 64 and the fixing portion 66 is provided with a mounting plate 73, which substantially stabilizes the connection between the guide pin 64 and the fixing section 66.

As an alternative to the illustrated exemplary embodiment of the guide rod assembly 26, the guide rod assembly 26 can consist only of a guide pin 64, which is offset from the mid-width of the guide rod 18 (see FIG. 1e) to this guide rod 18.

In FIG. 1g shows the running gear 10 in a different position, between the moved position and the closed position. From FIG. 1g it is seen that the guide rod 18 is made straight between the mounting portion 66 and the third hinge 24, made in the form of a bolted hinge. In other words, the guide rod 18 in the longitudinal direction is made without distortion. The guide rod 18, in addition, is made without bending. The guide rod 18, which is made straight and without bends, is thereby maximally rigid to bend and twist, and at the same time simple and economical to manufacture. During the closing movement of the running gear 10, the guide rod 18, with its end 74 opposite the third hinge 24, abuts directly to the control cracker 34. Thus, the non-control pin 64 and, accordingly, the non-guide sleeve 71 (see Fig. 1e) are adjacent to control cracker 34. Developed during the closing movement of the force that occurs when the emphasis of the chassis 10 in the control cracker 34, are transmitted through this directly through the guide rod 18.

In FIG. 1h shows the running gear 10 in a side view, i.e. in the direction of arrow 76 of FIG. 1g, however, without the control cracker 34. From FIG. 1h, the guide rail 32 has an upper protrusion 78 of the guide rail and a lower protrusion 80 of the guide rail. Due to the eccentric fastening of the guide pin 64 on the guide rod 18, the guide rod assembly 26, here it is a mounting plate 73, in separate sections extends under the upper protrusion 78 of the guide rail. And thus, the guide rod 18 does not run into the upper protrusion 78 of the guide rail. In general, due to the eccentrically mounted guide pin 64 (see Fig. 1f), the guide rod assembly 26 thus reaches the running gear 10, which is designed very close to the side wall 82, which is made between the upper protrusion 78 of the guide rail and the lower protrusion 80 of the guide rail. The running gear 10 is thereby substantially stabilized, and a favorable rearranging and closing movement is created.

Summarizing, we can say that this invention relates to a running gear with a guide rod mounted rotatably on a positioning rod. The guide rod by means of the guide pin, which in separate sections moves in the guide link of the running gear, is connected to the carriage of the running gear. The guide pin is fixed eccentrically. Due to such an eccentric fastening, this guide rod is located at a distance from the carriage in the area of the guide link. Due to this, the guide rod is also located at a distance from the guide rail, in which or on which the carriage is mounted for movement. The running gear therefore turns out to be very compact and stable.
