Description

Roller carrier for a sliding door

The invention relates to a roller carrier for sliding doors with a cross-sectionally approximately U-shaped support body whose one, first side leg serves as a mounting plate for attachment to a sliding door and at the other, second side legs at least one roller is mounted, and with a safety gate, which is guided transversely displaceable on the central web of the support body parallel to the axis of the roller between a securing and a release division and further protrudes in the securing position on the second side legs than in the release position. In known roller carriers, the safety slide is manually displaceable between the securing position, in which it secures the roller carrier against being hung from a guide rail, and a release position, in which the roller carrier can be unhooked from the guide rail.

In practice, the roller carrier is mounted together with the attached sliding door in the guide rail, the safety slide to be before hanging in the release position and must be pushed after hanging by hand in the securing position. This is often difficult because of the limited accessibility of the safety slide when the sliding door is suspended and with several roller carriers to be suspended. In addition, there is the risk that the roller carrier is not sufficiently secured against being hung from the guide rail in case of improper handling, such as when the safety slide is accidentally not or not completely transferred to its safety position.

The object of the invention is therefore to make comfortable and at the same time safer in a roller carrier of the type mentioned handling the mounting and unmounting.

This object is achieved in that the safety slide against the restoring force of a spring from the securing position is freely slidably mounted at least in the release position. According to the invention, when mounting the roller carrier in the guide rail of the safety slide located in the backup position against a lateral projection of the guide rail and is thereby moved against the restoring force of the spring in the release position. As soon as due to a further downward movement of the roller carrier of the safety slide on the lateral projection is pushed down past, the safety slide is automatically pushed by the spring back into the securing position and thus secures the hinged roller carrier against a detachment from the guide rail. Preferably, the securing arm on its side facing the roller on a ramp, which forms an obtuse angle with the second side legs to move the safety slide in a downward movement against the restoring force of the spring in the release position.

Particularly preferably, the safety slide on the release position is displaced into a locking position in which the safety slide is locked to the support body. Before being unhooked from the guide rail, the safety slides of all the roller carriers of the sliding door are manually moved into the locked position, and then the sliding door with its roller carriers can be easily and easily unhooked from the guide rail. Before re-attaching the roller carrier in the guide rail detent is released by lifting the operating handle and the safety slide is returned by the restoring force of the spring in its securing position.

The spring may for example be a separate pressure or a tension spring, which is arranged between the safety slide and the support body, or integrally formed on the safety slide. In the latter case, the spring is preferably formed by at least one integrally formed on the safety slide U-shaped leaf spring element whose free end is anchored to the roller carrier.

The safety slide is preferably designed as a one-piece plastic injection-molded part from a manufacturing-technical point of view as well as from a cost point of view.

The invention also relates to a sliding arrangement for a sliding door, with a guide rail and with at least one roller carrier configured as above, which is suspended with its at least one roller in the guide rail, wherein the safety slide engages in the securing position a lateral projection of the guide rail and in the release position does not engage under the lateral projection and wherein when mounting the roller carrier in the guide rail of the safety slide by a lateral projection the guide rail is deflected from the securing position against the restoring force of the spring in the release position.

Further advantages and advantageous embodiments of the subject invention will become apparent from the description, the claims and the drawings. Likewise, the features mentioned above and the features listed further can be used individually or in combination in any combination. The embodiments shown and described are not to be understood as exhaustive enumeration, but rather have exemplary character for the description of the invention.

Fuse position (Fig. 5a), in the release position (Fig. 5b) and in the detent position (Fig. 5c), in each case a view from above.

FIGS. 1a, 1b show a roller carrier 1 with a cross section U-shaped support body 2 with two parallel side legs 3, 4, which are connected to each other via a central web 5. The first side leg 3 serves as a mounting plate for attachment to a sliding door, not shown. The middle web 5 and the second side leg 4 are interconnected by an oblique connection Donate! 6, which in each case encloses an angle of approximately 45 ° with the central web 5 and the second side limb 4. The second side leg 4 carries outside a roller 7, which is mounted at a right angle to the second side leg 4 extending axis of rotation 8. As described in more detail below, the roller carrier 1 is suspended with the roller 7 in a guide rail. The two side legs 3, 4 are spaced apart from each other so that between them a further sliding door can be passed.

In a second side leg 4 open transverse slot 9 of the central web 5, a safety slide 10 is guided parallel to the axis of rotation 8 of the roller 7 between a securing and a release position transversely displaceable in the direction of the double arrow 11. For this purpose, the locking slide 10 at its opposite longitudinal sides in each case longitudinal grooves 12, in which engage the transverse slot 9 defining wall sections of the central web 5. The safety slide 10 is preferably a plastic injection molded part.

In the securing position shown in FIG. 1, the safety slide 10 engages with a hook-shaped securing arm 13 through an opening 14 of the oblique connecting leg 6 and projects laterally beyond the second side leg 4. The securing arm 13 has a blocking surface 15 facing away from the running roller 7 and a run-on slope 16 facing the running roller 7, which encloses an obtuse angle β (FIG. 3) of approximately 135 ° with the second side leg 4. The end face of the securing arm 13 is designated 17. The fuse arm 13 opposite end portion 18 of the safety slide 10 is formed as an operating handle for releasing a locking position, which protrudes in the securing position on the first side legs 3 of the support body 2.

As shown in Fig. 1 b, the safety slide 10 is biased in the securing position by a separate compression spring 19, which is supported at one end on the support body 2 and the other end on the locking slide 10. On the underside of the safety slide 10, a locking lug 20 is further provided which projects between the securing and the release position of the safety slide 13 in a recess 21 of the central web 5 and with a latching recess 22 (Fig. 2a) in the central web 5 cooperates. Furthermore, the safety slide 10 has on the upper side an engagement recess 23 with holding web 24 in order to simply bring the safety slide 10 into the latching position. Fig. 2a shows again clearly the transverse slot 9 with the recess 21 and the locking recess 22 in the central web 5 of the roller carrier 1. The two transverse slot 9 defining wall portions 25 of the central web 5 each have at the open end of a slot in the transverse slot 9 projecting end stop 26. As shown in Fig. 2b, the two longitudinal grooves 12 of the securing slide 10 on its side facing the securing arm 13 each have a projection 27 and in the region between the two projections 27 a longitudinal slot 28 which extends into the engagement recess 23. By compressing the safety slide 10 in the region of the longitudinal slot 28, the safety slide 10 can be inserted into the transverse slot 9. After releasing the safety slide 10 is held captive in the transverse slot 9 and is located with the projections 27 in the securing position on the end stops 26 and in the locking position on paragraphs 29 (Fig. 2b) of the wall portions 25 at. In the sliding arrangement 30 shown in FIG. 3, the roller carrier 1, on the first side leg 3 of which a sliding door 31 is fastened, is suspended with its roller 7 in a horizontal guide groove 32 of a guide rail 33. The guide groove 32 is overlapped by a lateral projection (eg web or flange) 34 of the guide rail 33.

In Fig. 3a, the safety slide 10 is shown in its securing position, in which the securing arm 13 engages with its locking surface 15, the lateral projection 34 of the guide rail 33. As a result, the roller 7 can only be raised by the distance a between the blocking surface 15 and the lateral projection 34, but can not be expelled from the guide rail 33 at the lateral projection 34, so that the roller carrier 1 is secured against being removed from the guide rail 33. The safety slide 10 is located by the compression spring 19 in the securing position. For hanging in the guide rail 33 of the roller bearing support 1 is mounted with its roller 7 by a combined downward and lateral movement in the guide groove 32 of the guide rail 33. In this case, the safety slide located in the backup position 10 runs with its run-on slope 16 or with its end face 17 against the lateral projection 34 and is thereby displaced against the action of the compression spring 19 in the direction 35 in the release position shown in Fig. 3b, in which the end face 17 of Safety slide 10 abuts the lateral projection 34. As soon as due to the further downward movement of the roller carrier 1, the safety slide 10 is pushed past the lateral projection 34 down and no longer rests against it, the safety slide 10 is pushed by the spring 19 back into its securing position shown in Fig. 3a. In the securing position of the safety slide 10 with its securing arm 13 is thus on the second side leg 4 before than in the release position.

To unhook the roller carrier 1 from the guide rail 33, the safety slide 10 is previously manually, with the help of the recessed grip 23 and the holding web 24, which is to prevent slippage during actuation, from its securing position in direction 35 on the release position also in the in Fig. 3c shown detent position shifted, in which the locking lug 20 engages in the locking recess 22 of the central web 5, whereby the securing slide 10 is held against the restoring force of the spring 19 in the locking position. In the locked position, the safety slide 10 obstructs the unhooking of the roller carrier 1 from the guide rail 33, since the securing arm 13 does not protrude beyond the second side limb 4 and also beyond the oblique connecting limb 6.

Before a renewed suspension of the roller carrier 1 in the guide rail 33, the latching lug 20 in the latching recess 22 is lifted by lifting the corresponding elastic end portion 18, and the safety slide 10 is moved back into its securing position.

From the safety slide 10 of FIG. 1, the safety slide 10 'shown in Fig. 4 differs in that here the spring 19' by two in one piece on Safety slide 10 'integrally formed U-shaped leaf spring elements 40 is formed, the side facing away from each protrude laterally beyond one of the longitudinal side of the safety slide 10'. The one ends 40a of the leaf springs 40 are integrally formed on the safety slide 10 'and additionally connected to one another via the retaining web 24 integrally formed on the safety slide 10'. In the embodiment shown, this retaining web 24 is also a stabilizing web. The other free ends 40b of the leaf springs 40 each have a latching tongue 42 on the underside.

As shown in FIG. 5, the latching tongues 42 are clipped into holding openings 43 of the central web 5. In Fig. 5a, the safety slide 10 'is shown in its securing position, in which the securing arm 13, the roller 7 partially overlaps. In Fig. 5b, the safety slide 10 'is manually shifted from the securing position in the direction 35 in the release position, against the restoring force of the thereby elastically bent U-shaped leaf spring elements 40. In Fig. 5c, the safety slide 10' is manually in direction 35 on the Release position shifted out into the rest position, and against the restoring force of the still further elastically bent U-shaped leaf spring elements 40th
