Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure of an electric sliding wall, in particular, a runner device.

(Prior Art) In general, a structure in which a panel of a sliding wall is suspended by a ceiling rail is generally configured to be suspended from the ceiling rail by a pair of upper runner devices arranged in front and rear of the traveling direction of the panel. .

By the way, compared to a system in which an operator manually moves a sliding wall, a system in which the sliding wall is self-propelled by a transmission driving force from a drive motor built in the panel is used for the panel suspension. There are some issues that must be taken into account as a holding structure. For example, a mechanism for transmitting driving force, a mechanism for supplying power source power to a panel drive motor from an external power supply device, or a control device for external control. The problem is that the configuration is for sending and receiving signals. In other words, the mechanism for transmitting driving force includes a structure that overlaps with the suspension configuration of the runner device that travels inside the ceiling rail, and in the configuration for power supply power supply and signal transmission / reception, this structure is usually used on the ceiling rail. It is necessary to lay an electrical trolley wire to maintain the electrical power collection relationship with the runner device.For these reasons, in the electric sliding wall, the panel moving type configuration by manual work is required. Then, the problems that were not necessary become problems that must be considered.

(Problems to be solved by the invention) According to the study by the present inventor, one of the problems is that the posture of the runner device for suspending the panel can be always stably maintained in the posture in the ceiling rail. It was recognized that doing one of the important issues.

Since this may pull out or store the panel with respect to the storage part, the ceiling rail fixed part and the movable part that can move such as rotation may be provided adjacent to each other in a continuous track, In this case, it is unavoidable that some joints are formed in these adjacent portions, and in the case of an electric sliding wall, if the drive wheels of the panel runner device may fall into this joint, it is relatively heavy. Since it may be difficult for the runner device that suspends the panel to travel, it is necessary to prevent the problem that driving wheels fall to the seam portion and make it impossible to travel. That is.

For this purpose, it is conceivable to take measures such as narrowing the joint or increasing the diameter of the drive wheel as compared with the joint.

However, these measures are not limited to narrowing the feel of the rail joint, and are not limited to making the wheel diameter too large. Furthermore, such measures alone cause various problems of the electric sliding wall. It was found that it was difficult to cope with. That is, as described above, in the electric sliding wall, it is necessary to collect current from the trolley wire laid on the ceiling rail, and for this reason, it is common to have a configuration in which the current collector provided in the runner device is engaged with the trolley wire. However, for example, as described in FIG. 5, in the structure of the type in which the pivotable ceiling rail 7 is arranged between the fixed ceiling rails 5 and 8, as described above, the drive wheels are provided at these joints. When it falls, the runner device 10 may be tilted due to rocking of the panel 6 and the electrical contact between the trolley wire 11 and the current collector 4 of the current collector may be lost. Is.

The present invention is intended to solve such various problems, and its purpose is to maintain the posture of the runner device running in the ceiling rail as stable as possible, and to provide the trolley wire and the runner device on the ceiling rail side. An object of the present invention is to provide a runner device that is devised so as not to cause a problem in electrical contact on the side.

(Means for Solving the Problems) The features of the present invention for solving the above-mentioned object are as follows.
A pair of running surfaces in the ceiling rails installed along both sides of the suspension bolts that suspend the panel are provided so that the runner device can run on the plurality of pairs of wheels assembled to this, and It is an electric sliding wall having a structure in which at least two pairs are used as driving wheels.

Particularly, as a typical configuration of the present invention, in the above-mentioned electric sliding wall, a current collector on the side of the runner device which comes into contact with the trolley wire laid on the ceiling rail is provided in an intermediate position in the traveling direction of a plurality of pairs of wheels of the runner device. It is especially important to have a configuration in which it is placed in a position.

(Embodiment) The present invention will be described below based on an embodiment shown in the drawings.

1 and 2 are views for explaining a runner apparatus 1 according to one embodiment of the present invention, and in this example, the runner apparatus has two pairs of drive wheels.

In this figure, reference numeral 1 denotes a runner device, and a frame (main body) of the runner device shown by reference numeral 2 has a suspension bolt 2a for suspending a panel (not shown) attached thereto and a gear train 2b. The driving force from the driving shaft 13 is transmitted to the four wheels 3 in total in two pairs. The details of the gear train 2b are omitted here, except for the illustration, but in short, the drive force transmitted from the panel 6 via the drive shaft 13 is transmitted to each of the four wheels.

Reference numeral 5 in FIG. 2 denotes a channel type ceiling rail, and a running surface 5a on which the wheels run is formed on the inner surfaces of both side arm portions at the lower position of the cross section.

Further, 4 is a current collector on the runner device side, and 14 is a trolley wire fixedly laid on the top surface of the ceiling rail.

FIG. 3 is a diagram for explaining a state in which the panel 6 is suspended by the pair of runner devices 1.

FIGS. 4 (a) and 4 (b) are views for explaining the degree of inclination considered when the runner apparatus 1 in the embodiment of the present invention travels on the joint portion of the ceiling rail 5, and FIG. In the figure (b), the runner device 5 travels on the traveling surface 5a with two pairs of drive wheels, and as a result, the current collector 4 on the runner side 5 is located at the intermediate position in the traveling direction of these two pairs of wheels, and the trolley on the ceiling rail side. It will be appreciated that it engages the line 14 and therefore a slight depression of the wheel is of little concern.

(Effects of the Invention) According to the electric sliding wall of the present invention, even if the wheels fall into the joint portion of the ceiling rail, since two pairs of wheels are driven, there is a problem that the vehicle cannot run. In addition, the current collector is arranged at an intermediate position between two or more pairs of wheels, and it is arranged so as to contact the trolley wire laid on the ceiling rail. Even if it occurs, the effect is small in the current collector portion, so that there is little possibility that the problem that the electrical contact between the trolley wire and the current collector is cut off occurs.
