Description

  The present invention particularly relates to a mounting tool for a sliding door, and includes a rail on which a carriage to which the sliding door can be fixed is movably held by a track roller separated from the carriage, and the mounting body is preloaded by a spring. And an elongate housing having an automatic pull-in mechanism, the carrier being movable along a guide track.

Patent Document 1 discloses a mounting tool for a sliding door, in which the carriage is connected to a housing having an automatic retracting mechanism.
The automatic retracting mechanism includes a carrier that is movable along a guide track, which is engageable with a fixed stopper for later moving the sliding door to the closed position by the spring force of the automatic retracting mechanism.
In such a sliding door fixture, there is a problem that the housing made of plastic in most cases is bent by the spring of the automatic retracting mechanism, and particularly in a limited space, a rubbing sound is generated between the housing and the rail. May occur.
As a result, the housing must be provided at a large distance from the surrounding rail.

Patent Document 2 discloses a slide door fixture in which a housing having an automatic pull-in mechanism is disposed between a carriage and a track roller.
Again, the automatic retracting mechanism can bend the housing, which can result in the disadvantages described above.

  Accordingly, it is an object of the present invention to provide a fixture that allows accurate guidance of an elongated housing and substantially prevents deformation of the automatic retracting mechanism by a spring.

  This object is achieved by a fixture having the features of claim 1.

In accordance with the present invention, at least one support member movable along the rail is provided in the central region on the housing, the support member supporting the housing in the central region.
This prevents excessive bending of the housing and avoids unwanted rubbing noise.

The support member is preferably disposed substantially centrally in the housing and between the two outer track rollers, in particular between the two track rollers disposed on opposite end surfaces of the housing, and is provided with a bearing or a set of track rollers. The track roller can also be provided on a known carriage.
The support member can be rotatably mounted on the housing, and the support member can preferably comprise at least one roller.
Thus, during movement of the support member along the rail, noise during movement can be reduced to a minimum.
The at least one track roller of the support member can have a smaller diameter than the track roller, thereby providing a compact configuration and other components, such as a spring of the automatic retracting mechanism, adjacent to the support member. Can be attached.
For stable support, the support member can comprise two rollers that are rotatable about a shaft and attached to the housing.

The support member can be placed on the upper side of the rail.
The track roller is supported on the other bottom side of the rail, so that when the housing is deflected upward, the support member prevents the housing from contacting the rail in the upper region.

According to an embodiment of the present invention, the rail has a U-shaped cross section, and a U-shaped leg is provided with an inwardly-facing web, in which a track for a track roller is formed.
The trajectory can be arranged to descend inward, preferably at an angle of 10 ° to 30 °, in particular 15 ° to 25 ° with respect to the horizontal direction.
As a result, the track roller is directed toward the center by the descending track, and the centering is performed by the force of the track roller guided on the track.
Furthermore, since not only the weight of the slide door but also the reaction force of the support member that presses the track roller against the track is applied to the track roller, the support member is also aligned with the center of the housing.
The one or more rollers of the support member are preferably in the connection area between the legs of the U-shaped rail.

In order to achieve a particularly compact structure, the spring of the automatic retracting mechanism is arranged adjacent to the rail track in the bottom region of the housing.
Since the deflection of the housing is prevented by the support member, the spring can be arranged off-center in the housing.
The housing can be configured at least 5 times, in particular 8 times in length with respect to width or height, which results in an elongated structure and can be placed in the rail.
In order to prevent severe impact noise, the automatic retracting mechanism can be equipped with a damper.
The damper is preferably arranged in the housing and connected to the carrier of the automatic retracting mechanism.

  Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

It is a perspective view of the fixture in an attachment position. It is sectional drawing of the fixture of FIG. It is a side view of the fixture of FIG. It is a figure which shows the fixture of FIG. 3 in a cross section partially. FIG. 4 is a diagram excluding rails around the fixture of FIG. 3.

The furniture 1 shown schematically in FIG. 1 comprises a furniture body 2 shown only partially, with a sliding door 3 suspended on the upper panel.
The slide door 3 is movably attached by a fixture 4, and a plurality of slide doors 3 can be provided on the furniture body 2.

FIG. 2 shows a cross section of the fixture 4.
The fixture 4 includes a rail 5 that is U-shaped in cross section and fixed to the recess of the furniture body 2.
The rail 5 has an upper connecting part 6 from which a leg 7 extends substantially vertically downward.
An inward web 8 is disposed at the end of the leg 7 where a track 24 for the track roller 11 is formed.
Further, the leg 7 is provided with a band 9 directed outward, and this band is placed on the bottom side of the upper panel of the furniture body 2 to form a stopper.

The fixture 4 further comprises a carriage 10, which is held movably on the rail 5 via a pair of track rollers 11 arranged therein.
The slide door 3 is suspended at least partially on the carriage 10.

The trajectory on the web 8 is inclined at an angle α with respect to the horizontal direction, which is preferably in the range between 10 ° and 30 °, in particular between 15 ° and 25 °.
Since the track 24 descends inward and the track roller 11 is provided in a shape that matches the track 24, the inner periphery of the track roller 11 in the axial direction is the outer periphery adjacent to the leg 7. It is getting bigger.

3 and 4 are side views of the fixture 4 with the rail 5 shown in cross section.
The fixture 4 is provided with a housing 13, on which a guide track 14 for the carrier of the automatic retracting mechanism is arranged.
The carrier can move along the guide track 14 in the longitudinal direction of the housing 13 and the rail 5 and can be locked to the curved end portion 15 of the guide track 14.
The carrier is further preloaded by a spring 18 in the closing direction, and the spring 18 is fixed to the housing 13 adjacent to the track roller 11 on the left side at the end 19 as shown in FIG. .
The opposite end 20 of the spring 18 is fixed to a carrier (not shown).

The housing 13 is connected to the carriage 10 via a connecting member 16, which includes two sets of track rollers 11, between which a frame from which a pin 12 on which the slide door 3 is suspended projects downward. .
In this way, the housing 13 is disposed between the center track roller 11 group and the left track roller 11 group.

A spring 18 configured as a tension spring preloads the sliding door in the closed position.
The carrier cooperates with a fixed stopper (not shown) for this purpose, which engages the carrier in the closed position, whereby the spring 18 is closed via the housing 13 and the carriage 10. A preload is applied to the sliding door 3.
Subsequently, the sliding door is pulled in the opening direction to open, so that the transport body moves from the end position along the track 14 and is moved to the curved end portion 15, thereby engaging the fixed stopper with the transport body. The combination is released and the sliding door can be freely moved along the rail 5.
By the new door closing process, the transport body reaches the fixed stopper together with the housing 13, and this fixed stopper releases the transport body from the curved end portion 15, and the transport body ends along the guide track 14 by the force of the spring 18. It is possible to move to the part position.
In order to stop the sliding door before reaching the closed position, a damper 21 configured as a fluid damper, such as a gas damper or a silicon damper, is further provided, which is movable and can be taken in and out of the housing of the damper 21. A piston rod 22 is provided.
The piston rod 22 is provided with a coupling member 23, which is fixed to the transport body.
The damper 21 substantially acts in one direction, that is, the slide door 3 is stopped in the closing direction, but the damper 21 can be smoothly operated in the opening direction.

The deflection of the housing 13 is such that the spring 18 constantly applies a load to the housing 13, so that the conveying body is disposed at the end position of the guide track 14 or is disposed at the locking position at the end portion 15. Can occur regardless of whether or not
In order to prevent the above-described deflection, a support member 17 is provided in the central region of the housing 13 between the track rollers 11 outside on the opposite end face of the housing 13, and this support member is movably movable in the rail 5. Attached to the curved portion 6.
In this way, the upward deflection of the housing 13 is prevented.

FIG. 5 shows the carriage 10 and the housing 13 without the rail 5.
The support member 17 is formed by two rollers connected to each other via a common shaft.
This allows the shaft to be attached to the two wall portions of the housing 13, for example locked and fixed.
The housing 13 is substantially U-shaped in cross section, thereby forming a damper 21 and a receiving part for the automatic retracting mechanism.
The guide track 14 for the carrier is formed on the wall portion of the plastic housing 13.
The spring 18 of the automatic retracting mechanism is provided in the bottom region of the housing 13, which is provided in the web 8 of the rail 5 adjacent to the track 24.

When the weight of the slide door 3 is loaded on the carriage 10, the weight G <b> 1 acts on the carriage 10, and this weight is substantially absorbed via the four track rollers 11.
The track roller 11 is held by the track 24 on the web 8, and the force F1 acts on the sliding surface because the track 24 is inclined with respect to the horizontal direction.
This force can be diagonally directed outward and divided into a vertical force V1 and a horizontal force H1.
Since the opposing track rollers 11 have the same inward horizontal force H <b> 1, these forces cancel each other out in the carriage 10.
The four track rollers 11 therefore distribute the weight G1 to the force V1.

When the weight is applied to the track roller 11 disposed on the opposite open side and attached to the housing 13, a force F2 is loaded on the track 24, and this force is divided into a vertical force V2 and a horizontal force H2. Is done.
The horizontal force H2 of the two track rollers 11 cancels each other because the web 8 of the track 24 is inclined in different directions.

When the housing 13 is bent by the force of the spring 18 and a load is applied to the support member 17, the support member 17 configured as a roller presses against the connection portion 6 of the rail 5 with a force G <b> 2.
The housing 13 is then pressed downward, whereby a part of the force G2 is absorbed by the set of track rollers 11 arranged on the open side, and further force is absorbed by the four track rollers 11 of the carriage 10.
Regardless of the magnitude of the force G2, since the track 24 is inclined, the alignment of the housing 13 in the rail 5 to the center is ensured.

In the illustrated embodiment, the housing 13 is coupled to the carriage 10 via a connecting member 16.
Of course, it is also possible to integrate the carriage 10 in the housing 13, and in this case, the track rollers 11 may be provided in only two sets or in three sets or more instead of three sets.
Further, it is possible to provide only one roller as the support member 17 on the upper side of the housing 13 instead of the pair of rollers.
The rollers can also be placed on the inclined area of the rail 5 instead of the horizontal connection part 6 above the rail 5 in order to also align the center of the housing 13 in the rail 5 in the upper area, for example.

  The fixture 4 is particularly suitable for a sliding door in a cupboard, but can also be used for other purposes in which the sliding member is held movably along the rail 5.
