Abstract

(57) [Abstract] [Purpose] To reduce the labor of a worker by making it possible to easily adjust the strength of the tensile stress of a spring member that opens and closes the wings of a wing wheel. In order to achieve the above object, a pair of blades having an L-shaped cross section, which are upper portions of a roof and side walls, are formed on both left and right sides of a support beam stretched between a front center and a rear center of a luggage carrier between the top centers. By pivoting up and down, and by attaching one end of an elastic spring member to the upper portions of the front wall and the rear wall and attaching the other end to the edge of the blade, the blade can be moved to a predetermined angle. While rotating upward, the tensile stress of the spring member acts to rotate the blade downward, but when the blade is rotated upward by a predetermined angle or more, the spring member causes the blade to rotate. The spring member is configured to act as a tensile stress, and one end of the spring member is attached to the protrusion member so that the position of the protrusion member can be easily adjusted. A wing characterized in that its strength can be adjusted easily. .

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an opening / closing device for a wing vane.

[0002]

[Prior art]

 A wing with a L-shaped cross section and a pair of blades at the top of the side wall hinged vertically to the left and right sides of a support beam stretched between the front and rear walls of the luggage carrier. Vehicles are widely used for easy loading and unloading of luggage, and various devices have been devised as a device for rotating the pair of blades up and down, in addition to the device that uses the expansion and contraction force of the cylinder, in particular, the actual public. 54-2496, which utilizes the tensile stress of the spring member, is widely used because of its simple structure, no power required, and easy mounting.

[0003]

[Problems to be solved by the device]

 In the device utilizing the tensile stress of the spring member, once the both ends of the spring member are fixed and mounted, the strength of the tensile stress cannot be easily adjusted by adjusting the length dimension of the spring member. Moreover, until the blade is rotated upward by a predetermined angle, at least a tensile force of the spring member and a force against the rotational force due to the weight of the blade are necessary.

On the other hand, the force for rotating the blade upwards to a predetermined angle varies depending on the individual operator, and especially for a woman, the force may be insufficient. When rainwater or the like infiltrated the hood with the cover covered, the labor of the operator was considerably large, and it was not easy to try to adjust the tensile stress of the spring member.

An object of the present invention is to reduce the labor of an operator by making it possible to easily adjust the strength of the tensile stress of the spring member.

[0006]

[Means for Solving the Problems]

 In order to achieve the above purpose, a pair of vanes with an L-shaped cross section, which are the upper part of the roof and side walls, are vertically installed on both left and right sides of the support beam stretched between the center of the top between the front wall and the rear wall of the luggage carrier. By pivotally attaching a hinge, by attaching one end of an elastic spring member to the upper part of the front wall and the rear wall and attaching the other end to the edge of the blade, the blade is moved upward by a predetermined angle. While rotating, the tensile stress of the spring member acts to rotate the blade downward, but when the blade is rotated upward by a predetermined angle or more, the spring member moves the blade upward. Strength of tensile force of the spring member by attaching one of the ends of the spring member to the protruding member so that the position of the protruding member can be easily adjusted. Wing vehicle characterized by being configured for easy adjustment Providing opening and closing device of the blade.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a mounting structure of a protruding member for mounting one end of a spring member according to the present invention, and FIG. FIG. 3 shows a state in which the wing vehicle is opened and closed up and down, and FIG.

A pair of roof beams having a L-shaped cross section and a pair of upper side walls are formed on both left and right sides of a support beam 16 stretched between the center of the top between the front wall 12 and the rear wall 14 of the luggage carrier 10 shown in FIG. The blades 18 and 18 are hinged via a hinge 20 so as to be vertically rotatable.

As shown in FIG. 2, one end 24 of the elastic spring member 22 is attached to the upper portion of the front wall 12 and the rear wall 14, and the other end 26 is attached to the edge of the blade 18, thereby While 18 is rotated upwards up to a predetermined angle A (that is, the inclination angle of the chain line a connecting the one end 24 of the spring member 22 and the rotation center of the hinge 20), the tensile force of the spring member is Is rotated downward, but when the blade is rotated upward by a predetermined angle A or more, the spring member acts as a stress that pulls the blade upward.

Therefore, conventionally, once the both ends of the spring member 22 are fixed and mounted, it is not possible to easily adjust the strength of the tensile stress by adjusting the length dimension of the spring member 22. Until the blade 18 is rotated upward by a predetermined angle, at least a tensile stress of the spring member 22 and a force against the rotational force due to the weight of the blade 18 are required.

As shown in FIGS. 1 and 2, the present invention attaches one end 24 of the spring member 22 to the upper portions of the front wall 12 and the rear wall 14 via a mounting member 28 and the other end 26 thereof. The blade 18 is attached to a protruding member 30 provided on the end edge of the blade 18, and the lower portion of the protruding member 30 is screwed into a long bolt 32, and the long bolt 32 rotates to slide inside the guide member 34. By doing so, the position of the end portion 26 of the spring member 22 can be easily adjusted, and the length dimension of the spring member 22 can be adjusted, so that the strength of the tensile stress can be easily adjusted.

The long bolt 32 is rotatably mounted inside the guide member 34 by a lock nut 34.

[0013]

【effect】

 As described above, according to the present invention, one end of the spring member of the wing vane opening / closing device is attached to the protrusion member so that the position of the protrusion member can be easily adjusted. Since the strength of the tensile stress of can be easily adjusted, the labor of the operator can be reduced.
