Description

  The present invention relates to a panel suspension structure in which partition panels, exhibition panels, and the like are suspended so as to be movable along an upper rail, its runner, and upper rail.

  In this type of suspension structure, the upper rail is connected to the main direction rail that is laid along one direction and the main direction rail at the rail intersection, and the right direction rail that is laid along the direction perpendicular to the main direction rail. A pair of runners that run while being guided by the upper rail are provided at both ends in the running direction at the upper end of each panel.

  For example, Patent Document 1 describes a suspension structure in which a movable display panel is suspended from runners on rails in vertical and horizontal directions that are connected orthogonally to each other. In this suspended structure, the runner is configured such that the four traveling wheels provided on the four cantilever shafts that protrude in the horizontal direction so as to form a cross shape from the base roll while rolling on the rail. Has been. The traveling display panel can move from the vertical rail to the horizontal rail or from the horizontal rail to the vertical rail by changing the running direction of the runner to the orthogonal direction at the intersection.

Japanese Patent No. 2729773

  However, according to the general suspension structure as described in Patent Document 1, when the runner is located at the rail intersection of the vertical (main direction) rail and the horizontal (right angle) rail, this Since the rail inner side surface (rail wall surface) that supports the runner does not exist at all (in the case of a cross-shaped intersection) or only one surface (in the case of a T-shaped intersection), it is possible to maintain the runner posture correctly. In some cases, it was impossible to run.

  In order to maintain the runner's posture correctly even at the rail intersection, conventionally, two types of runners attached to the panel are prepared, and a four-wheel runner that can change direction at the rail intersection is used on the door end side. On the side, a two-wheel runner was used for only going straight at the rail intersection. Further, a projection is provided at the top of the four-wheel runner so that the four-wheel runner does not go straight at the rail intersection, and this projection collides with a stopper provided on the inner upper surface of the upper rail at the rail intersection. It was composed.

  However, preparing and attaching two types of runners to each panel not only causes an increase in the number of parts, but also requires each runner to be selectively attached to the door end side or door end side of the panel. The workability on site was deteriorating. In addition, the suspension structure using two types of runners is a storage structure that requires the door end side runner and the door bottom side runner on the main direction rail to be simultaneously turned to a pair of right angle rails. Could not be applied at all.

  Accordingly, an object of the present invention is to provide a panel suspension structure and its runner and upper rail that can correctly maintain the runner's posture at the rail crossing even if the runner attached to the panel is shared by one type. .

  According to the present invention, there is provided a panel suspension structure comprising an upper rail and a runner that engages with the upper rail and is capable of traveling along the upper rail and that suspends the panel from the upper rail. Is done. The upper rail includes a main direction rail and a right-angle rail connected to the main direction rail at a rail intersection and extending in a direction perpendicular to the main direction rail. The runner has a base, four axles mounted on the base so as to protrude in the horizontal cross direction, and four wheels that are rotatably supported by the four axles and can run on the inner lower surface of the upper rail. And four upward projecting portions provided at the four corners of the base so as to be positioned in front of and behind the four wheels, and a suspension support shaft extending downward from the center of the base and connected to the panel It has. In particular, according to the present invention, a pair of guide grooves are provided along the upper rail on the inner upper surface of the upper rail so as to engage the four upper protrusions of the runner and guide the movement of the four upper protrusions. It has been.

  A pair of guide grooves are provided on the inner upper surface of the upper rail along the upper rail. The four upper protrusions of the runner engage with the pair of guide grooves, and the four upper protrusions move. It is comprised so that it may guide. As a result, the runner is supported by the pair of guide grooves not only during traveling in the main direction rail and the right-angle direction rail, but also in the rail intersection, so that the posture of the runner can be always maintained correctly. Therefore, it is possible to share one type of runner and not only increase the number of parts, but also eliminate the need for selective installation of the runner on the door end side or door end side. The workability at the site is greatly improved. The present invention can also be applied to a rail structure in which a pair of runners on the main direction rail is simultaneously changed into a pair of right-angled rails.

  It is preferable to further include a ridge member provided along the upper rail at the center in the width direction of the inner upper surface of the upper rail and forming a guide groove with the inner side surface of the upper rail.

  More preferably, the ridge member has a transverse groove in a direction orthogonal to the longitudinal direction of the ridge member at the rail intersection.

  It is also preferable that the base is provided with four downward projections whose front ends are close to and opposed to the inner lower surface of the upper rail at the four corners described above.

  It is also preferable to further include a panel mounting body that is attached to the hanging support shaft of the runner and can be fitted into a recess provided in the panel.

  In this case, the panel mounting body is fitted into a recess provided at the upper end of the side of the panel near the door tip or the door butt, or is fitted into a recess provided at the door tip or the door butt of the panel. More preferably.

  According to the present invention, a runner and an upper rail used for the above-described panel suspension structure are further provided.

  According to the present invention, the runner is supported by the pair of guide grooves at the rail intersection as well as when traveling on the main direction rail and the right-angle direction rail, so that the posture can be always maintained correctly. . Therefore, it is possible to share one type of runner and not only increase the number of parts, but also eliminate the need for selective installation of the runner on the door end side or door end side. The workability at the site is greatly improved. The present invention can also be applied to a rail structure in which a pair of runners on the main direction rail is simultaneously changed into a pair of right-angled rails.
