Description

FITTING FOR LIFT-SLIDING DOORS OR WINDOWS AND RUNNER OF SUCH A FITTING}

The present invention provides a fitting for a lift-sliding door or window as claimed in the preamble of claim 1 and a slide for use in such an accessory as claimed in the preamble of claim 10. It relates to a running shoe or a runner.

Lift-sliding doors and fittings suitable for such doors are known in the art. The basic function of such doors is that the doors of each door can be raised and lowered with respect to the outer frame and at the same time they can move within the doors of the door, so that when the door is opened, for example, the door is first raised vertically and then horizontal To move. The casement door is closed in the reverse direction. As another function, such a lift-sliding door may have a tilt function.

In the attachment device used for the lifting-sliding doors known in the technical field (German Patent No. 78 16 563, German Patent No. 203 04 001), the lifting mechanism or the handle of the lifting gear is operated manually. Then, the connecting rod guided on the locking rail moves in the axial direction, whereby the slider housing comprising the slider or the slider positioned on the lower horizontal brace of the swing door is placed in the longitudinal direction of the slider and the lower horizontal brace or Move horizontally with respect to the bearing element located on the lower horizontal brace. The elevating device consists of a rectangular peg guide arranged at an angle between each slide housing and the corresponding bearing element, and the lifting device changes the distance between the sliding housing and the lower horizontal brace of the swing door It functions to elevate the door with respect to the outer door frame.

The disadvantage of this design is that in a lifting device designed as a rectangular hook guide, a significant frictional loss during lifting action, i.e. a sliding friction loss between a rectangular slot that functions as a lifting curve and a hook nail that works with this rectangular slot, This is accompanied by. To reduce this frictional loss, it is typical to design the hooks into sleeves that can rotate on fixed bolts in the slider housing, but this requires lubrication of the sleeves after continuous use of lift-sliding doors or windows. Can not guarantee this lubrication.

In general, it is also possible to reduce frictional losses or frictional forces by allowing the rollers to work with the lifting bends by means of ball bearings or needle bearings. However, this method greatly increases the total cost of the lifting-sliding attachment.

It is an object of the present invention to provide an accessory device which avoids the above drawbacks and reduces frictional losses by means of a simple design. This object is achieved by an accessory device according to claim 1. The slider is the subject of claim 9.

The accessory device according to the invention prevents friction between the elements of the elevating device. Instead, a control element designed as a roller or bolt and operating in conjunction with the lift bend rolls on the lift bend and also on the beveled surface of the bolt or roller bearing.

The friction loss (rolling resistance) that occurs in the present invention is much less than in the case of sliding friction that occurs in the previously known accessory device. This means in particular that the lift of the casement of a door or window is quite easy. Thus, it is possible to eliminate the relatively large actuating levers often used for lift-sliding doors or windows and replace them with shorter visually more attractive levers.

The lifting bends and the bolt or roller bearings can have various shapes, for example straight or at least partially curved. In addition, bolt or roller bearings, in particular their rolling surfaces, can be variously designed, for example in grooves, rectangular slot shapes and the like.

The invention is described below based on an exemplary embodiment with reference to the drawings.

1 shows a door of a building, which in a known manner consists of an outer door frame 1 and a swing door located in the door frame. This swing door is designed, for example, as a lift-sliding swing door with an additional tilting function, and thus can be elevated vertically, move horizontally and tilt to open and close.

The lifting-sliding attachment device, generally indicated at 3 in FIG. 1, is arranged in the swing door 2 or in the swing door frame 2.1 in a known manner, for example of the swing door frame 2.1 of the groove. A locking rail 4 fixed to the vertical portion 2.1.1 and using a manually operated gear device 5 as indicated by the double arrow V in FIG. 1 by a predetermined stroke. And a drive rod that is movable in the longitudinal direction of the lock rail.

The lifting-sliding attachment 3 also comprises two slides 6 and 7 located on the lower horizontal brace 2.1.2 of the swing door frame 2.1, each sliding body being shown in the illustrated embodiment. Are provided with two rollers 8. The rollers guide the sliders 6 and 7 on a horizontal roller rail or guide rail 9 located in the lower door area of the door frame 1 so that the swing door moves horizontally as indicated by the double arrow (H). Can be opened.

Each sliding body 6 and 7 has a sliding door 2 in the corresponding operation of the gear device 5, i.e. when the handle lever pivots in one direction and the drive rod of the locking rail 4 moves accordingly. It is designed to be vertically lowered when it is raised vertically or the handle lever is moved in the opposite direction. For this purpose, the movement of the drive rod of the locking rail 4 is carried out on the sliders 6 and 7 and their slider housings 11 by the corner guides 10 in the region of the lower corner of the swing door frame 2.1. Switch to working horizontal motion. While the corner guide 10 operates directly on the adjacent slider 6 and its slider housing 11, the slider 7 and its slider housing (located in the other bottom corner area of the swing door frame 2.1) ( 11 is connected to the slider housing of the slider 6 by a connecting rod 12.

The slider 7 is shown in detail in FIGS. 2 to 4. The slider 7 consists of a slider housing 11 together with two rollers 8 and one bearing element 13, which is mounted to the bottom of the lower horizontal brace 2.1.2. In the embodiment shown, the slider housing 11 comprises two thin plates 14 with parallel rows of steel, which are parallel and separated from each other and connected by connecting elements 15 at both ends. . 2 shows the connecting element 15 at one end of the two thin plates 14. At the other end of the slider housing 11, the two thin plates 14 are likewise connected to each other by such connecting elements. Each connecting element 15 is made of a die-cast metal, for example, such as die-cast zinc.

Slider 7 is mounted on the swinging door frame 2.1, and the two thin plates 14 have their longitudinal sides (double arrows H) oriented horizontally and parallel to the longitudinal sides of the lower brace 2.1.2. The surface lies in a plane parallel to the plane of the swing door 2. The longitudinal side of the slider 7 is also the same as the longitudinal side of the two thin plates 14.

Between the thin plates 14 two slide carrier rollers 8 can rotate on bearing bolts 16 fastened to both ends of the thin plates. In the space between the thin plates 14 and between the two rollers 8, the bearing element 13 forms a mounting plate with its upper part 13.1 protruding upwards over the upper long side of the thin plate 14 and The lower part 13.2 is arranged to protrude downward beyond the lower long side of the thin plate 14. The bearing element 13 is fastened in a groove located at the bottom of the lower brace 2.1.2 of the swing door frame 2.1 by suitable means, for example a screw, an upper plate-shaped portion 13.1.

The bearing element 13 is located between the thin plates 14 of the part 13.3 provided between the two parts 13.1 and 13.2 and forms two guide faces, each guide face being two of the thin plates 14. It leans on one of its opposing inner sides.

In order to elevate the swing door 2, a hole 17 is provided in the part 13.3 of the bearing element 13 which serves as a lifting bend, which is designed as a rectangular slot and its long side is a slide carrier ( 7) and the longitudinal axis of the thin plate 14 are formed with an acute angle α, which is open toward the corner guide 10.

There are rollers or bolts 18 in the lifting holes 17, the bolt axes of the bolts being oriented perpendicular to the thin plate 14 plane and guided in the thin plate 14 at both ends. The bolt 18 has an intermediate bolt portion 18. 1 whose larger diameter is equal to or slightly smaller than the width of the lifting hole 17. The bolt 18 also has a bolt portion 18.2 at each end that is significantly smaller in diameter than the intermediate bolt portion 18.1. The bolt portions 18.1 and 18.2 are all located on the same axis.

The bolt is supported in the lifting hole 17 by the bolt portion 18.1. In the bolt portions 18.2, both parts having the same diameter, the bolt 18 is mounted to the bearing in the sheet 14 in the slot 19 at both ends. The width of the slot 19 is equal to or slightly larger than the diameter of the bolt portion 18.2. Further, the slots 19 have the same length and this length is much shorter than the lifting hole 17, and the longitudinal side of the slot 19 is arranged so as to be parallel to the longitudinal extension of the lifting hole 17. The slots 19 have an upper end portion of each slot 19 in FIG. 4 adjacent to an upper end portion of the lifting hole 17 and a distance between each end of the slot 19 and its adjacent end portion of the lifting hole 17 is a bolt portion ( It is arranged to coincide in the axial direction perpendicular to the plane of the thin plate 14 such that approximately half of the difference in diameter between 18.1 and 18.2 is.

In addition, the length of the lifting hole 17 and the slot 19 is the bolt part when the bolt part 18.1 rolls on the long side of the upper part of the lifting hole 17 which contacts the part 13.1 in FIG. 4, for example. 18.2 is defined to be rollable on one long side, ie the long side of the lower portion of each slot 19 in FIG.

Now when the gear device 5 is operated via a connecting rod guided on the locking rail, through the corner guide 10, through the slide carrier 6, and through the connecting rod 12, an arrow H ′ in FIG. 4. As shown in FIG. 4, the pulling force is applied to the slide carrier housing 11 of the slide carrier 7, and the bearing element 13 passes through the lifting holes 17 and the bolts 18, which act as lifting curves. It rises vertically corresponding to (V '). When the slide carrier housing 11 is moved in the direction opposite to the arrow H ', the door 2 connected with the bearing element 13 is lowered in the direction opposite to the arrow V'. The slots 17 and 19 and the bolt 18 thus form a lifting device for the slider 7, which is indicated by reference numeral 20 in FIGS. 2 to 4.

Since the parts 13.1 and 13.2 protrude beyond the guide face formed by the part 13.3, these parts 13.1 and 13.2 are in the raised position and also in particular the bearing element 13 and thus the hinged door 2. It functions as a stationary element in the lowered position in order to limit the vertical upward movement of the portion, whereby the part 13.1 leaning against the upper long side of the thin plate 14 at the lowered position carries the load of the sliding door 2 on the slide carrier. To the housing 11, thereby relieving the load of the bolt 18.

The bolt 18 of the illustrated embodiment is loosely supported in the lifting hole 17 and the two slots 19. Since the diameter of the bolt portion 18.1 is larger than the diameter of the bolt portion 18.2 and the axial length of the bolt portion 18.1 is equal to or slightly smaller than the distance between the opposing inner surfaces of the thin plates 14, the bolt 18 ) Is confined to the bearing 13 so as not to fall out between the two thin plates 14.

The inclination of the slots or the inclination of the lifting holes 17 and the lifting bends formed thereby determine the transmission ratio between the horizontal movement of the slider 7 and the upward movement of the bearing element 13. This transmission ratio can be changed by designing the lifting hole 17 in a straight or essentially straight line, for example, by designing the curved portion at least at one end. This makes it possible to optimize the torque occurring at this lever over all rotation angles of the gear device 5 lever, for example, in order to prevent torque or force peaks during operation.

The slider 6 is at least the same as the slider 7 with respect to the lifting device.

The present invention has been described based on an exemplary embodiment. It is to be understood that modifications and variations of the present invention are possible without departing from the spirit of the invention as a basis of the present invention.

The inclination with respect to the horizontal plane of the longitudinal extension of the elevating hole 17 and the slot 19 was assumed to be the same. It is conceivable to differ from this design.

In addition, by designing a bearing hole that works together with the bolt portion 18.2, the bolt portion 18.2 having a smaller diameter can be obtained.

The particular characteristic of the slide carrier described is that the rolling of the bolts 18 of the two slots 19 and the lifting holes 17 prevents the sliding sliding in the area of the lifting device 20 of the slider, the swing door (2) can be raised with much less energy consumption.

 The rolling sliding friction between the elements of the elevating device 20 is prevented by the rolling of the bolts 18 in the elevating holes 17 and the slots 19, thus raising the door 2 with a smaller physical force. You can.
