Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a mounting device that allows easy mounting of a winding shaft for winding up a sunshade sheet.

[Prior art]

Developed in 1988-161033 as a sunshade in which the winding shaft for winding the sunshade sheet could be rotated by a motor.
The invention described in the publication No. 1 is known. This invention uses a clutch in which the motor is built into the winding shaft, the rotating shafts protruding from both ends of the winding shaft are inserted into a pair of left and right brackets, and the rotation of the motor is interposed between the shaft and the inner peripheral surface of the winding shaft. The winding shaft is transmitted to rotate the winding shaft.

[Problems to be solved by this idea]

The problem with the above-described invention is that it is difficult to attach the winding shaft. That is, to attach the winding shaft, the rotating shaft is passed through the bracket while supporting the winding shaft, and fixed by some means to prevent the rotating shaft from coming off the bracket.
Therefore, two workers are required: one to support the winding shaft and one to secure it by screwing the bolts together.

The object of this invention is to provide a sunshade sheet winding shaft mounting device that facilitates the work of mounting the winding shaft.

[Means for solving problems]

The sunshade sheet winding shaft mounting device according to this invention has a mounting portion protruding from one of a pair of brackets toward the other bracket, and a motor built in one end of the winding shaft for winding the sunshade sheet. A protruding portion is provided protruding toward the bracket, and either the protruding portion or the mounting portion is formed with a fitting recess that opens toward the outer circumference, and the other is formed in a prismatic shape to fit into the fitting recess. After the winding shaft is placed on the winding shaft, the protrusion is fixed to the bracket.

〔Example〕

Hereinafter, this invention will be explained in detail based on an embodiment shown in the drawings.

What is shown in FIG. 3 is a sunshade, in which brackets 1, 1 are attached to the left and right sides of a building frame, and a support frame 2 is fixed horizontally to these brackets 1, 1.
Arms 3, 3 are attached to the left and right sides of the support frame 2,
The intermediate portions of the arms 3, 3 are bendable, and the bending angle is widened by the biasing force of a built-in spring, so that the tips of the arms 3, 3 can move toward the outdoors. A front frame 4 is attached to the tips of the arms 3, 3. A pair of brackets 5, 5 are attached to the left and right ends of the support frame 2. A winding shaft 6 is rotatably spanned between the brackets 5, 5, and a sunshade sheet 7 is wound around the outer periphery of the winding shaft 6.
The tip end is fixed to the front frame 4. Arm 3,
3 becomes larger, the front frame 4 protrudes toward the outdoors, and the sunshade sheet 7 is removed from the winding shaft 6.
Pull out. When the winding shaft 6 is rotated to wind up the sunshade sheet 7, the front frame 4 retreats toward the building frame against the spring force of the arms 3, 3.

This invention relates to the mounting portion of the winding shaft 6 to the bracket 5 in the above-mentioned sunshade.

There is a circular mounting hole 8 at the top of one bracket 5.
is drilled. A disc-shaped fitting body 9 is fitted into the mounting hole 8 . A prismatic mounting portion 10 with a square cross section is protruded from one end in the centerline direction of the fitting body 9, and a flange portion 11 extending toward the outer circumference is formed at the other end. Further, a bolt hole 12 is formed in the fitting body 9 so as to penetrate in the direction of the center line and open at the tip of the mounting portion 10 . This fitting body 9 is fitted into the mounting hole 8 so that the mounting portion 10 projects toward the other bracket 5. The fitting body 9 is fixed by pressing a bolt 30, which is threaded so as to penetrate from the outer circumference of the bracket 5 into the mounting hole 8, into contact with the outer circumferential surface.

A horizontally penetrating fitting hole 13 is formed in the upper part of the other bracket 5, and a spherical sliding contact part 14 is recessed continuously in the circumferential direction at the longitudinally intermediate portion of the inner peripheral surface of the fitting hole 13. has been done. A disk-shaped bearing body 15 having a spherical outer peripheral surface is fitted in such a manner as to be in sliding contact with this sliding contact portion 14 . The bearing body 15 has a horizontally penetrating shaft hole 16, and a spherical sliding contact portion 14.
The outer peripheral surface is in sliding contact with the shaft hole 16, so that the angle of the shaft hole 16 can be changed.

A motor 17 is built into one end of the cylindrical winding shaft 6, and a rotating body 19 is attached to the rotating shaft 18 of the motor 17, which presses against the inner peripheral surface of the winding shaft 6 via a one-way clutch. When the motor 17 rotates, the winding shaft 6 rotates together with the rotating body 19. Engagement parts 20, 20 are provided upwardly and downwardly in a protruding portion of the motor 17 from the winding shaft 6. Motor 1
A mounting member 21 is attached to the winding shaft 6 of 7. The mounting member 21 is a vertically long rectangular board 22.
One side has groove-shaped fitting parts 23, 23 that open in directions facing each other up and down, and the other side has a fitting recess 24 with a U-shaped cross section that opens downward in the upper and lower middle parts. A protruding portion 25 is provided in a protruding manner.
One side of the substrate 22 is opened in the fitting recess 24 at the upper and lower middle portions thereof. A screw hole 29 having a female thread is screwed into the inner peripheral surface. Such a mounting member 21
The fitting parts 23, 23 of the motor 17 are the engaging part 2 of the motor 17.
The mounting member 21 is attached to the motor 17 by screwing nuts 27, 27 onto bolts 26, 26 which are fitted into the bolts 26, 26 and pass through the fitting parts 23, 23 and the engaging parts 20, 20. .

A shaft body 28 is provided protruding from the other end of the winding shaft 6.

To attach the winding shaft 6 between the brackets 5, 5, the shaft body 28 is inserted into the shaft hole 16 of the bearing body 15 built into the upper part of one of the brackets 5, and then fitted with the connecting shaft 25 at the other end. The fitting recess 24 is lowered from above and the mounting portion 10 of the other bracket 5 is fitted. Therefore, the connecting shaft 25 rests on the mounting part 10 and the winding shaft 6
will be temporarily received between brackets 5 and 5.

Bolt 30 inserted into bolt hole 12 of fitting body 9
is screwed into the screw hole 29 of the mounting member 21 and fixed.

This invention has the above-mentioned configuration, but the connecting shaft 25 on the motor 17 side is made into a prismatic shape, the fitting recess 24 is formed in the mounting shaft 10 on the fitting body side, and the fitting recess 24 opens upward. The connecting shaft 25 may be placed on.

[Effect of idea]

This invention has the above-mentioned configuration, with one bracket having a mounting portion protruding toward the other bracket, and the motor attached to one end of the winding shaft having a protruding portion protruding toward the bracket. However, a fitting recess is formed in either the protruding part or the mounting part, the other is fitted into the recessed part, and the winding shaft is placed thereon, after which the protruding part is fixed to the bracket.

Therefore, the winding shaft can be easily attached between the brackets by one worker, and the construction cost is reduced.

Since either the protruding part or the mounting part is formed into a prismatic shape, it does not rotate even if it is fitted into the fitting recess, and the winding shaft can be stably supported during temporary support.
