Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a canvas top structure for an automobile that can open and close an opening formed in the roof of a vehicle body.

(Prior Art) In recent years, in order to obtain a sense of openness above the vehicle body, progress has been made in the development of automobiles with canvas tops in which an opening is formed in the roof of the vehicle body and the opening is covered with a canvas top that can be opened and closed. It is being In the case of an automobile having such a structure, even when the canvas top is in an open state, the canvas top is located in a folded state at the rear end of the roof opening.

Nowadays, as user demands become more diverse, there is a demand for maximizing the use of the roof opening, and there is a problem in that the structure described above cannot sufficiently meet this demand.

Therefore, proposals have been made to make the canvas top removable from the vehicle body when it is in an open state, thereby maximizing the use of the roof opening. For example, as disclosed in Japanese Unexamined Patent Publication No. 63-61629, a canvas top and a flat sub-frame on which a drive unit for opening and closing the canvas top is arranged are attached to the vehicle body. Some are separable, and the canvas top and subframe can be removed upwards as a unit, if necessary.

(Problems to be Solved by the Invention) In the case of the above-mentioned known example, the canvas top and subframe are integrally removed upwards, but these have a considerable weight and are attached to the vehicle body roof. Since the work is done at a high place, it may be difficult to remove the canvas top, especially for users with weak strength such as female users, who require considerable force to put on and take off the canvas top.

Invention 1, which has been made in view of the above points, allows the canvas top to be easily attached and detached, and maintains the posture of the canvas top at the time of detachment until the next attachment. The purpose is to

(Means for Solving the Problems) In the present invention, as a means for solving the above problems, guide rails extending in the longitudinal direction of the vehicle body are provided on both sides of an opening formed in the roof portion of the vehicle body, and the kite rails are provided on both sides of an opening formed in the roof portion of the vehicle body. on the rail,
In a canvas top structure for an automobile, in which a canvas top covering the opening can be freely opened and closed is connected to the guide rail via a kite shoe that is slidably engaged with the guide rail, the canvas top is attached to the rear of the guide rail in an attached state. A movable rail portion is provided which is continuous with the guide rail and is removable from the vehicle body side, and is engaged with the guy knee when the canvas top is in the open state.

(Function) In the present invention, the following effects were obtained by the above means.

That is, when removing the canvas top, the canvas top in the open state and the movable rail portion to which the guide shoes of the canvas top are engaged are removed from the vehicle body in a state where they are integrally connected. As a result, the entire roof opening can be left open.

(Effects of the Invention) According to the present invention, guide rails extending in the longitudinal direction of the vehicle body are disposed on both sides of the opening formed in the roof portion of the vehicle body,
A canvas top structure for an automobile, in which a canvas top that covers the opening so as to be openable and closable is connected to the guide rail via a knee that is slidably engaged with the guide rail. A movable rail part is provided that is continuous with the guide rail in the installed state and is removable from the vehicle body side, and that is engaged with the guide shoe when the canvas top is in the open state. When removing the canvas top, the canvas top in the open state and the movable rail portion to which the knee of the canvas top is engaged are integrally connected and can be removed from the vehicle body, unlike the conventional example. Compared to the case where the canvas top and the sub-frame with a part of the guide rail are removed as one unit, the force required for removal work can be significantly reduced, making it easier for even female users to attach and detach the canvas top. This has the great effect of making it possible. Furthermore, since the guide nonny is engaged with the movable rail section when the canvas top is removed, the engagement state between the guide shoe and the movable rail section is maintained even when the canvas top is removed. This also has the effect of improving the workability of attaching and detaching the canvas top.
