Description

Running part for a sliding door leaf

The present invention relates to a running part for a sliding door, comprising a door leaf side fixable support member with a fixed thereto and a roller or a slider bearing journal and a Sicherungsseinrich- device by means of which a detachment of the roller or the slider is prevented from a track of a running rail.

Sliding door leaves are usually provided with two running parts whose roles or sliders are suspended in an upper, horizontally arranged track. The rails usually have trough-shaped raceways, in which the rollers or sliders are guided and thus a displacement of a door leaf perpendicular to its plane is avoided. In such suspended and guided door panels, it is important to prevent the roller or the slider of one of the running parts can be excavated from these trough-like guideways.

Forces that can cause such lifting or unhooking occur, for example, when hitting a door leaf on a stationary end stop, in which case the door is at its, the decelerating end stop adjacent lying end tends to be lifted upwards. Also by incorrect operation of a user unintentionally forces can be exerted on a sliding door sash, which could cause a hanging of the door leaf.

Therefore, corresponding running parts are provided with a fuse that prevent unintentional unhooking of a sliding door wing in that an element of a safety catch engages below the running rail and strikes against the underside of the running rail when lifting the sliding door leaf before a roller or a slider completely out of a trough-like guideway is lifted out. If, on the other hand, a sliding door leaf is to be suspended deliberately, the corresponding safety devices can be brought into a position in which a lifting of the sliding door leaf is possible so far that the rollers or sliders are moved out of the tub-like guide track upwards. In the hitherto known securing systems, the forces which become effective in the securing position and in the case of lifting of the sliding door flies are absorbed by the connection region of the securing devices to the supporting part. According stable and resilient the connection areas must be interpreted so far.

The present invention has for its object to provide a running part of the generic type, which ensures a highly reliable security against unhooking, without the connection area between the fuse and support member is significantly burdened.

This object is achieved in that the securing device consists of a relative to the support member about a direction parallel to the direction of sliding sliding door wing pivoting rocker which is within an opening of the support member and in the securing position with its upper, the roller or the slider end facing below a running rail is located and the other end of a lower boundary plane of the opening of the support member is directly opposite and is supported in the load case thereof.

The advantage of this construction is essentially that the forces occurring in the load case - ie in the case of lifting a Schiebetürfiügels - by striking the rocker on the underside of the rail forces are intercepted at the lower boundary plane of the opening of the support member, without affecting the axis around which the rocker is pivotally, is charged significantly. Since the support member must be fixed so stable anyway on a sliding door that even in continuous operation and dynamic loads this connection is guaranteed, the forces occurring in the event of a brief lifting a sliding door leaf can also be safely intercepted by the support member and the rocker.

Further features of the invention are the subject of dependent claims.

Embodiments of the invention are illustrated in the accompanying drawings and will be described in more detail below.

In FIG. 1, the reference numeral 1 designates a running rail of a sliding door cabinet 2, which is only hinted at.

Two sliding door panels extending in different planes are designated by the reference symbols 3 and 4. In this case, the designated by the reference numeral 3 sliding door leaf is closer to the sliding door cabinet 2 than the sliding door panel designated by the reference numeral 4, which is why it is also possible to speak of the rear sliding door 3 and the front sliding door 4. The rear sliding door leaf 3 is hooked by means of two fixed to the sliding door leaf 3 running parts 5 and the front sliding door leaf 4 via two fixed to this sliding door leaf 4 running parts 6 in the track rail 1.

In FIG. 1, only one of the mentioned running parts 5 or 6 of the two sliding door leaves 3 and 4 is shown, since it is obvious that each sliding door leaf 3 or 4 is equipped with such running parts 5 and 6 in the region of its two outer vertical side edges.

In the following, the design of a running part 5 for the rear sliding door leaf 3 will now be described in detail, since this running part 5 is the subject of the present invention.

Said running part 5 comprises a supporting part 7, a supporting axle journal 8 connected thereto, on which a running roller 9 is mounted, and a securing device 10 by means of which a detachment of the running roller 9 from a running track 1a of the running track 1 can be prevented.

On the support part 7 are also on both sides of the roller 9 lying end stop pins 11 are provided, one of which in a known manner upon reaching an end position of the sliding door leaf 3 at a rail side fixed put end stop 12 (see Figures 1 and 7) abuts and depending on the design of the end stop 12 can be fixed non-positively in order to avoid accidental springing back of the sliding door leaf 3.

The securing device 10 is, as shown in FIGS. 4-6 particularly clearly, from a rocker 13, which lies in the installed state within an opening 4 of the support member 7 and about an integrally formed by two axle stub 15 axis parallel to the direction of displacement of the Schiebetürfiügels. 3 runs, is swiveled within limits. The two stub axles 15 are used in bearing grooves 16 of the support member 7 starting from the back of the support member 7 and can by the design of the bearing grooves 16 in its intended storage position, for example by

Snap or the like to be fixed.

As a result, a prefixing of the rocker 13 is achieved within the opening 14 of the support member 7, wherein the prefixing can be improved by the interaction of integrally formed on the rocker 13 locking lugs 17 and associated latching pockets 18 in the lateral boundary region of the opening 14 of the support member 7th These locking lugs 17 and locking pockets 18, an unwanted pushing back of the rocker 13 against its insertion, ie in the direction of the back of the support member 7 back, are practically avoided, so that the transport of appropriate fitting parts, the rockers 10 remain practically in the pre-assembled by the manufacturer position.

Furthermore, 15 further locking lugs 19 are integrally formed on the rocker 13 adjacent to the stub axles, which are assigned in a corresponding position further latching pockets 20 in the region of the opening 14 of the support member 7. These locking lugs 19 adjacent to the stub axles 15 and the detent pockets 20 corresponding thereto serve to fix the position of the rocker 13 in its securing position, which will be explained in detail below.

With reference to FIGS. 5a to 5c, the function of the rocker 13 can easily be explained:

FIG. 5 a shows a position of the rocker 13 which can be referred to as an unsecured position, ie, in the position of the rocker 13 shown in FIG. 5 a, the roller 9 would be unhooked from the track 1a of the track rail 1 possible. The upper, the running rail 1 adjacent part of the rocker 13 can move easily in this unsecured position on the lateral boundary of the track rail 1 and the roller 9 are suspended in the running rail 1 or moved out of this, as shown in Figure 5a. In Figure 5b it is shown that the roller 9 is suspended and supported in the track 1a of the track rail 1. As before, the rocker 13 is in an insecure position, while in Figure 5c, the rocker 13 has been pivoted about the stub axle 5 so far that the upper end 3a of the rocker 13 is below the track rail 1 or in other words engages under this track rail 1, while the opposite lower end 13b of a lower boundary plane 14a of the opening 14 (see Figure 4c) is directly opposite. This position shown in Figure 5c of the rocker 13 is fixed by the stub axles 15 adjacent latching lugs 19 and the corresponding latching pockets 20.

If now, in a position according to FIG. 5c, lifting of the sliding door flies 3 tends to occur, the upper end 13a of the rocker 13 abuts the underside of the running rail 1. This results in reaction forces that can be intercepted by the support of the lower end 13b of the rocker 13 at the boundary plane 14a of the opening 14. In this case, the stub axle 15 are not appreciably loaded, condition for the function ate only that in the bearing area of the rocker 13 within the support member 7 tolerance-related and / or elastic range of motion for the stub axle 15 are given.

Since the stub axle 15 of the rocker 13 seen from the back of the support member 7 are inserted into the bearing grooves 16 and the support member 7 is screwed firmly on the surface of the sliding door leaf 3, a retraction of the rocker 13 is now effectively prevented even under load.

As FIGS. 5a-5c in particular make clear, the axle journal 8 carrying the roller 9, which for reasons of stability should preferably be made of metal, is riveted within the support part 7, preferably by a wobble riveting 8a. But it is also possible, the axle 8 in a plastic-made support member 7 by appropriate geometric design safely and highly resilient to the support member 7 made of plastic

overmolded. Alternatively to the use of a roller 9, the use of a slider comes into question, although a roller 9 is to be regarded as a higher-quality solution.

In any case, an embodiment of the running part 5 is preferred, in which both the support part 7 as well as the rocker 13 made of plastic and only the axle 8 is made of metal.

In this case, of course, the end stop pins 11 are integrally formed on the support member 7.

In principle, it is provided to deliver the running part 5 in the secured position of the rocker 13 according to FIG. 5c. When attaching the sliding door leaf 3, the rocker 13 is pivoted by abutting the upper end portion of the side edge of the track rail 1 in its unsecured position shown in Figures 5a and 5b, so that the disability-free suspension of the roller 9 in the track 1a of the track rail 1 is possible. The pivoting back of the rocker 13 in the securing position can now be done manually, but it is also possible, the rocker 13 against the action of a return spring

pivot, so that an actuation of the rocker 13 when hanging is not required, but only in a possible disassembly or a deliberately desired unhooking of the sliding door leaf 3, in which case just the rocker 13 swung back by manual operation in an unsecured position and in this Position must be locked during unmounting.

In the figures 7 - 10 an embodiment of the invention is shown, in which the running part 5 is provided in addition to the structural features described so far with an override 21 for the front sliding door 4 relative to the rear sliding door 3. This Überfahrsicherung 21 consists of an injection molded part, preferably made of plastic and can be fastened by means of a screw 22 on the sliding door leaf 3, wherein a locking pin 23 which engages in a bore 24 of a Endanschlagzapfens, ensures a positionally accurate and positionally secured positioning of the override 21. The Überfahrsicherung 21 can be arranged on the end stop pin 11, which does not come into engagement with the end stop 12. In the displacement of a lateral arm 25 of the running part 6 for the front sliding door 4, the rollover protection 21 is provided with a stop surface 26 against which the lateral boom 25 of the running part 6 abuts before both sliding door leaves 3 and 4 are completely shifted from each other. Thus, a complete overrunning of the two sliding door leaves 3 and 4 relative to each other and the associated risk of a collision of the front sliding door 4 with protruding in its displacement grips of the rear sliding door leaf 3 or even a pinch of the hand on the handle safely avoided. The abutment surface 26 of the override 21 is preferably resilient, so that when you hit the side arm 25, a certain damping effect arises.

This exemplary embodiment shows that a running part 5 according to the invention with a safety device 10 for preventing an unwanted unhooking of a sliding door leaf can be combined in a simple manner optionally with a highly effective safety drive 21, which corresponds to the running part 6 in the region of the running rail 1.

As an alternative to the exemplary embodiment according to FIGS. 7-10, the override safeguard 21 may also be provided with a locking boring instead of a locking pin 23, which in the installed state encompasses an end stop pin 11.

Likewise, it is conceivable to form an override safety device 21 integrally with the carrying part 7 in the case of a carrying part 7 made of plastic. However, this increases the variety of parts of the running parts 5 to the equipment for the rear sliding door 3, as always only the closer to the stop 12 mounted running part 5 can be provided with an override 2, such as already described above. In addition, then continue to be observed by the manufacturer, whether the running part 5 with a right or left arranged end stop 12 should correspond. For the installation of a rear Schiebetürfiügels 3 thus two different running parts 5, according to the desired direction, required. Bezugszeicheniiste
