Description

Caster frame for moving doors (2)

The invention relates to a caster frame for a moving door, which has a running roller carrier on which at least one or a plurality of running rollers are rotatably supported, and the running roller rolls on a rail, wherein the running roller carrier is run There is a retaining member for preventing lifting up, the retaining member allowing the running roller carrier to be raised in a first position and preventing the running roller carrier from rising from the rail in a second position latched.

DE 202 12 222 U1 discloses a running roller carrier for a moving door, in which a cross-sectional U-shaped carrying portion is provided, the connecting portion being provided with a horizontally movable molding part. The molded part can be held by a cantilever from a frame of the rail below to hold the "running roller carrier" on a rail. If the molded part is pushed horizontally, the running roller carrier is released and raised from the rail. A disadvantage of such a running roller carrier is that a larger space is required in the horizontal direction due to the horizontal movement of the molding section.

It is therefore an object of the present invention to provide a caster frame for a moving door in which the retaining member that prevents lifting out is constructed in a compact manner and can be easily operated.

This object is achieved by using a caster frame having the features of claim 1 of the patent application.

According to the invention, the caster frame has a retaining member that prevents lifting and falling out, and has a tongue (Lasche) which is placed under the rail when the latch is in the position of the latch and is designed to be lowered to release the latch from the rail. . Therefore, the holding means for preventing the falling out is moved in the vertical direction. In order to keep the running roller carrier on the rail, only a minimum construction space is required in the horizontal direction. In addition, the retaining member that prevents the fall out can be caused in a simple manner by mechanical means such as a mover, a frame-turn lever or other member.

In a preferred design, the caster frame designed or having the running roller carrier has a vertical wall section on which the retaining member is guided in a movable and/or pivotable manner. The running roller carrier can also be formed only by vertical wall sections, so that the caster frame can be particularly suitable for rear moving doors.

In order to positively guide the holder which prevents the lift-out, it is advantageous for at least one curved guide to be guided over this vertical wall. Here, the curved guide has an end portion that is bent into an angular shape to hold the retaining member in the position of the latch.

In particular, it has an end section which is bent substantially in an angular shape in the horizontal direction. This provides a designated retaining member that prevents the moving door from rising in the vertical direction.

According to another variant embodiment, the tongue of the holder which is raised and raised is prevented from being supported on a pivotable lever.

Here, the lever can be fixed to the running roller carrier via a rotating shaft and the lifting prevention member can be raised or lowered. The lever should be snapped into a latched position to avoid unintentional release of the latch.

In order to maintain the retaining member that is prevented from falling out of the latch position, a spring is preferably provided to prestress the retaining member. In this case, the spring is fastened in the running roller carrier and is pivoted against a holding section of the holder.

In order to facilitate the simple action of the retaining member which prevents the lifting out, the retaining member which is prevented from falling out protrudes beyond the running roller carrier with a grip portion in the first position. The jaws will lift the handle and pivot or move the grip section to unlock the running roller carrier.

The invention is described in detail below with reference to the accompanying drawings.

Figures 1 to 3 show a moving door (1) which is held in a movable manner by one or several caster frames (2). Each caster frame (2) comprises a substantially plate-shaped running roller carrier (3) which is fixed to the moving door (1) by a plurality of screws (4) and can be fixed via a height adjustment means if necessary. A running roller (5) is rotatably supported on the running roller carrier (3), and the running roller (3) is movable on a rail (6).

The rail (6) has an angular running section with two adjacent running paths (7) for the roller (5). In addition, the rail (6) encloses a specific cover (9) with an upper section (8) so that the moving door (1) can be hung on the rail (6) for movement.

In order to prevent the moving door (1) from being improperly moved, and the running path (7) of the running roller (5) of the running rail (5) rising out, a retaining member for preventing the falling out is provided.

As shown in Figures 2 and 3, the retaining member (11) which prevents lifting up and down comprises a horizontal tongue (10) which ties the rail (6) from below in the area below the running path (7). . The retaining member (11) for preventing the falling out is designed to be substantially plate-shaped, and has an upper curved guiding member (12) and a lower curved guiding member (13), and the two curved guiding members (12) (13) are each A pin (14) passes through. Further, a handle portion (17) is formed at the upper end of the retaining member (11) which is prevented from falling out, and is disposed in a hollow of the running roller carrier (3).

The position of the retaining member (11) that prevents lifting is shown in Fig. 4A at a latch. The tongue (10) is placed directly below the rail (6).

In order to unlock the holder (11) and raise the running roller carrier (3), the holder (11) is moved downward as shown in Fig. 4B. Thus, the tongue (10) forms a space with the lower side of the rail (6), so that the moving door (1) can be raised sufficiently to raise the running roller (5) from the running path (7).

Figure 5 shows the details of the holder (11). The upper curved guide (12) has an angled end section (16) that extends generally horizontally and serves to retain the retaining member (11) in the latched position. If the pin (14) is provided in the region of the angled end section (16), the retaining member (11) cannot move upward. Only when the holder (11) is pivoted by the handle section (17) (Fig. 4B), the pin (14) leaves the angular end section (16) of the curved guide (12), so the holder (11) Can be lowered.

A modified design of the retaining member (11) and the caster frame (2) is shown in Figs. 6A and 6B, in which the above embodiment is supplemented by attaching a spring (20) to the running roller carrier (3). The spring (20) includes a bendable leg (21) that holds the retaining member (11) in the latched position. To this end, the contour of the leg (21) of the spring cooperates with an edge of the retaining member (11) and is bent as the retaining member (11) moves along the upper and lower curved guide members (12) (13). Here, the bendable leg (21) is deformed such that it holds the retaining member (11) in the first latch position and the second latch position.

7A, 7B, the caster frame of Figures 6A, 6B is in the position of the latch and the release latch. In the position of the latch, the handle section (17) slightly projects the running roller carrier (3) so that it can be easily pinched and it moves in the hollow of the running roller carrier (3).

An exploded perspective view of the caster frame (2) of Figs. 6 and 7 is shown in Figs. 8A and 8B. Two springs (22) are formed on the spring (20) which are inserted into the associated openings (23) of the running roller carrier (3). In this way, the spring (20) can be easily installed and accurately positioned. In addition, a bolt (24) is also formed on the leg (21) of the spring, which is fixed to the running roller carrier (3) to increase the clamping force on the holder (11). The holder (11) is held in a movable manner on the running roller carrier (3) by means of two pins (14).

Figure 9 shows a third embodiment of a caster frame (2') of the present invention which moves a moving door (1) movably on a rail (6). The caster frame (2') comprises one or several running rollers (5) which are rotatably supported on the running roller carrier (3'). In order to hold the moving door in order to prevent lifting from a running path (7) of the rail (6), there is provided a retaining member (11') which prevents lifting and falling out, which comprises a tongue which is bent into an angle ( 10'), the moving door (6) is placed under the tongue. The retaining member (11') can be raised or lowered by a lever (12') which supports the pivotable manner.

10A and 10B show the retaining member (11') in the latching position, so that the tongue (10') is placed below the running path (7) of the rail (6), and the retaining member (11') utilizes a belt ( 14') is coupled to the lever (12'). The lever (12') is supported on the running roller carrier (3) for rotation about a shaft (13') and includes a handle section (17') for actuating the retaining member (11').

In order to release the latch (11') from the latch position, the lever (12') is pivoted in a clockwise direction until the position shown in Figures 11A and 11B is reached, and the lever (12') is pivoted. (13) pivoting to lower the holder (11') with the connecting member (14'). Therefore, there is a gap between the tongue (10') and the rail (6) so that the running roller (5) can rise from the running path (7) of the rail (6).

An exploded view of the caster frame (12') is shown in Fig. 12. The retaining member (11') is designed in the form of a frame strip having an angled tongue (10') supported by a pin (15). In '), the lock is also used to support the connecting element (14'). Furthermore, the connecting element (14') is coupled to the lever (12') so that when the lever (12') is pivoted, the retaining member is raised or lowered. Here, the lever (12') can be engaged in the first position and/or the second position.

Other action mechanisms may also be used to raise or lower the holder, such as a knee lever mechanism.
