Description

The present invention relates to a canopy bone guide device for a canopy that can be opened and closed.

[Conventional technology]

Conventionally, the canopy bone guide device of this type of openable canopy is, for example,
A plurality of canopy guide members are fitted into each of a pair of left and right guide paths formed by facing each other in parallel with a set of guide grooves in the left-right direction, and the axes of the left and right lower ends are in the vertical direction. By connecting each of the canopies facing toward the to the canopy guide member, a plurality of canopies are configured to be movable along the guide path, and the canopies are covered with a flexible canopy. In addition, a structure for forcibly moving by an appropriate drive mechanism (see, for example, Japanese Utility Model Publication No. 46-2508) and two awning travel guide paths in which two box-shaped rails are integrated are separated by a certain distance. Parallel to each other and installed on four or more stanchions, and the wheels of the awning holding metal fittings (corresponding to the canopy guide members) are placed on the guide rails, and the awning holding metal fittings are placed at the center of the fittings. A configuration in which the above are connected (for example, Japanese Patent Laid-Open No. 54-60
718).

In addition, since the canopy generally has an arched shape, its center of gravity is always far above the connection point between the canopy and the canopy guide member, and its standing posture is always unstable. There was a structural problem that it tended to tilt in the front and rear directions, that is, in the canopy opening and closing direction.

[Technical problem to be solved by the invention]

However, in the conventional structure as described above, the attitude of the canopy guide member is extremely unsatisfactory when opening and closing the awning because the attitude control of the canopy guide member in the guide groove has not been taken into consideration. Stable and variable. In particular, when adopting a configuration in which the lower end portion of the canopy bone is vertically connected to this canopy guide member, that is, a configuration in which a downward load is intensively applied to one side of the canopy guide member, It is difficult to achieve the original guidance operation, and one side of the canopy guide members on the left and right leads or lags behind, causing the left and right sides of the canopy to be jerky, which prevents smooth movement. One encounters a situation in which the bone guide member appears to be caught in the groove and is prevented from moving.

Then, as a result of investigating the root cause of the above-mentioned malfunction, the following facts were found. That is,
In the conventional general structure, basically, a pair of rollers are attached to both ends of the support, and this is simply loosely fitted in the guide groove (a relatively large gap is formed between the inner wall of the guide groove and the roller). Since it is a structure that is only (a certain state), when the awning is opened and closed, the support is pulled or a pressing force is applied, and further, the canopy is tilted forward and backward, It was quickly found that the canopy guide member had its correct orientation along the original direction of travel.

By the way, in order to maintain this correct posture, ideally, it is necessary to apply an equal stress to both rollers at all times, but this is not possible as a practical problem, so the above problems cannot be solved at all. As it is today, consumers are still struggling. .

Therefore, the present invention has been earnestly developed in view of these drawbacks of the conventional structure, and adopts a configuration in which the load of the awning and the canopy is concentratedly applied to one side of the canopy guide member, while providing guidance. It is an object of the present invention to provide a canopy bone guide device for an openable canopy in which the posture of the canopy guide member in the premises can be properly maintained as expected.

[Means for Solving the Problems]

A canopy bone guide device for an openable canopy according to the present invention to achieve the above object is a pair of left and right guides formed by facing a pair of two guide grooves in parallel with each other at a predetermined interval in the left-right direction. A plurality of canopy bone guide members are fitted in each of the paths, and a plurality of canopy bones are guided by connecting each of the canopy bones whose left and right lower end axes are directed vertically to the canopy bone guide member. In an openable canopy that is configured to be movable along a path, has a plurality of canopy bones covered with a flexible canopy, and is forcibly moved by an appropriate drive mechanism, the two guide grooves have a predetermined vertical direction. The canopy guide member is disposed at a predetermined interval in the vertical direction, and the canopy guide member is orthogonal to the vertical axis and two support rollers that are vertically spaced from each other and that rotate about the vertical axis. Equipped with one steady rest roller that rotates around the horizontal axis Two of the three continuous rollers are parallel to each other with a horizontal axis serving as a rotation axis of the steady rest being separated by a predetermined distance, and are fixed to one surface side of the bracket in a vertical posture, and On the other surface side, an axis is formed by providing a connecting portion for connecting a vertical lower end portion of the canopy whose vertical direction is directed, and an inner side wall surface distance of the guide groove and a diameter of the supporting roller are almost equal to each other. The support rollers are inscribed on both sides of the inner side wall of the guide groove, and the front steadying rollers are inscribed in the groove opening gap and inscribed in the upper and lower opening edge faces of the gap. It is a thing.

[Action]

In the canopy guide device for an openable canopy according to the present invention configured as described above, when the drive mechanism is actuated, a large number of canopy guide members housed in a pair of upper and lower guide grooves on the left and right respectively are guided grooves. Along, the canopy bone moves forward or backward to open and close the canopy.

At this time, a pair of upper and lower support rollers are attached to the bracket of the canopy guide member on one side of the bracket, and a pair of front and rear support rollers are attached at a predetermined interval in the traveling direction of the guide member, and a steady rest is provided. There are also a pair of front and rear rollers, and in addition,
Since both the support roller and the steady rest roller are not loosely fitted, the support roller is inscribed on both inner wall surfaces of the groove, and the steady rest roller is inscribed in the upper and lower opening edge surfaces of the groove gap, respectively. The bracket itself has a structure in which an unbalanced load as described above is applied to the direction of travel of the guide member and also in a direction orthogonal to the direction of the guide member. In spite of this, it is difficult to tilt easily, and the desired desired posture is maintained well.

At the same time, there are two guide grooves vertically spaced apart by a predetermined distance, and the lower end vertical portion of the canopy bone is connected across the canopy guide members provided in the two guide grooves, that is, the guide groove. In contrast to this, the canopy guide member that holds the desired stable posture with little inclination tilts the canopy forward and backward, left and right, and vibrates. Effectively counters stress,
It works better to prevent canopy tilt.
