Abstract

PURPOSE:To absorb a deviation and an error in a rail span by interposing a position correcting means, which consists of sliding members slidable along guide shafts in a direction orthogonal with the moving axis of a roof, on a running carriage for supporting the roof. CONSTITUTION:Guide shafts 6, 6, which are faced in a direction orthogonal with the moving axis direction of a roof supported running-movably along a guide track of rails 3, 3 or the like, are fixed onto a running carriage 4 of the roof. Next a position correcting means 5 is constituted by slidably fitting sliding members 7 7 to the guide shafts 6, 6, and a beam 8 of the roof is supported onto the carriage 4 through the position correcting means 5. In this way, the relative displacement in a transverse direction between the guide track and the roof can be permitted.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a retractable roof in which the roof is movably supported by guide rails such as rails, and in particular to a retractable roof that has improved comfort when opening and closing. This invention relates to a roof moving device.

(Prior art) In general, retractable roofs have several or several levels of movable roofs that move oppositely or adjacently in the opening and closing directions, and when closed, collide with each other or become adjacent to each other. It is supported by a traveling carriage by guide rails such as, etc., and is self-propelled with a motor or the like attached to the traveling carriage itself, or is driven by a winch or the like.

(Problem to be solved by the invention) Specifically, the guide rail runs on a hemispherical curvature surface or on a rail attached to an arch beam.
Even if the rail gauge is constant, if the distance between the rails and other rails (rail span) fluctuates, the roof members that open and close may compete with each other and become unable to travel.

The reason for this is that retractable roofs generally have an arched shape, making it difficult to improve construction accuracy, and that solar heat hits only one side of the arch that makes up the building, causing thermal stress that partially distorts the arch beams. 2 laid there due to the curvature surface
Snow between book rails.

This can be caused by wind loads, etc.

The present invention has been made in view of the above circumstances, and its purpose is to provide a retractable roof moving device that can absorb deviations and errors in rail spans.

(Means for Solving the Problems) In order to achieve the above object, a retractable roof moving device according to the present invention provides a retractable roof moving device in which the roof is movably supported by a guide rail such as a rail. A position correction means is installed between the roof and the guide rail, which is formed by fitting a sliding member into a sliding white flower on a guide shaft oriented in a direction perpendicular to the axial direction.

(Function) In other words, a position correction means is interposed between the roof and the guide rail,
This allows the roof to move in a direction perpendicular to the axis of movement of the roof. For example, when the guide shaft is fixed toward the roof of the traveling truck and the other sliding member is fixed toward the roof, the guide shaft and the sliding member will be shifted relative to each other, resulting in the guide rail and the roof being fixed. Allow relative deviation of .

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a cross section of a retractable roof. In this embodiment, a retractable roof 2 is supported by arch beams 1 extending in pairs from the center of the building to the periphery. Each arch 1,
1a has rails 3, 3a laid on its surface as shown by a certain rail gauge A in FIGS. 2 and 3, and each retractable roof 2, 2a runs on the rail 3.3a. It is supported by trolleys 4 and 4a so that it can run freely.

That is, the retractable roofs 2 and 2a supported by the respective arch beams 1 and 1a are adjacent to each other, and the retractable roofs 2 and 2a are adjacent to each other smoothly, and the adjacent edges are sealed for waterproof reasons. They really touch each other. Therefore, rails 3, 3a
The mutual spacing (1 nord span) B must be constant. However, this rail span B is not always constant due to problems with the allowable limits of construction accuracy and rail distortion due to temperature differences, and as a result, competition may occur between the adjacent joints of the retractable roofs 2 and 2a. There is a risk that the traveling truck 4 may come off the rails or the retractable roof 2.2a itself may be damaged, so a position correcting means 5 is interposed between the traveling truck 4, 4a and the retractable roof 2.28.

The position correcting means 5 includes a guide shaft 6 extending orthogonally across the traveling axis direction of the rail 3, and a sliding member 7 externally fitted onto the guide shaft 6. The guide shaft 6 is plate-shaped, and the sliding member 7
The outer bottom I is formed in a shape similar to a cylinder with a U-shaped cross section so as to straddle this. Then, a retractable roof 2.28 is fixed to the sliding member 7, and the other In this case, the guide shaft 6 is fixed to the traveling carriages 4, 4a.
4a and the retractable roof 2.2a) are in a state in which free movement is allowed also in a direction perpendicular to the direction guided by the rail 3. The details are shown in FIG.

Reference numeral 8 in FIG. 3 is a beam 8 of the retractable roof 2, and the retractable roof 2 supports the roof beam 8 on the arch beam 1 with a traveling truck 4 so as to be movable.

That is, the roof beam 8 is fixed to the sliding member 7.

Further, the guide shaft 6 is fixed to the traveling carriage 4.

Now, when the rail span B of the rail 3 becomes eccentric as rail span B' due to some condition or situation, and the rail 3 becomes an eccentric rail 3B, the rail gauge A remains the same and becomes eccentric as rail span B'. An unreasonable force will be applied to the retractable roof 2 located at the adjacent position due to the eccentric dimension. At that time, the position correction means 5 can absorb the deviation from the rail span B to 1 nord span B'. That is, the relative sliding movement between the guide shaft 6 and the sliding member 7 allows the roof beam 8 to be maintained in a natural position without strain. This position correction means 5
The sliding force is caused by the reaction force received from the adjacent retractable roof 2, and the guide shaft 6 and sliding member 7 move relative to each other until this reaction force disappears, and unreasonable force is applied to the adjacent edge of the retractable roof 2. The natural force that is not applied corrects the retractable roof to its natural movement position in the direction of the opening and closing axis.

(Effects) As explained in detail above, according to the retractable roof moving device according to the present invention, in a retractable roof in which the roof is movably supported by a guide rail such as a rail, the roof can be moved in the direction of the roof movement axis. Since the position correction means is provided with a sliding member slidably fitted onto the guide shaft facing in a direction perpendicular to the roof, the position correction means is interposed between the roof and the guide rail, and the roof and It can absorb deviations in position relative to the guide rail. That is,
The guide shaft or sliding member allows the roof or the guide rail to escape in a direction perpendicular to the guide rail in response to the distortion or deflection of the guide rail.

In addition, with respect to horizontal shaking of the movable roof caused by wind, earthquakes, etc., the position correcting means acts as a buffering force to loosen the force acting on the guide rail in the lateral direction.

This is also effective in releasing the stress that concentrates on local parts of the guide rail supporting the retractable roof due to the effects of heat, wind, etc. even when the retractable roof is not being opened or closed.
