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]

As a structure for attaching a winding shaft for winding up a sunshade sheet to a bracket, an idea described in Japanese Utility Model Application Publication No. 60-70123 is known. This device has a built-in worm gear at one end of the winding shaft, an operating box that allows the winding shaft to be rotated by a lower operating rod, and the winding shaft is attached to a pair of left and right brackets. It is.

[Problems to be solved by this invention] The problem with the above-mentioned invention is that it is difficult to attach the winding shaft. That is, to attach the winding shaft, the winding shaft is supported by hand, and a bolt is passed through the bracket from the side, and the bolt is screwed into the operation box to attach the winding shaft to the bracket. Therefore, two workers are required: one to support the take-up shaft and one to thread the bolts.

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 device for installing a sunshade sheet winding shaft according to this invention has an operation box attached to one of a pair of brackets, a rotatable mounting shaft that projects toward the other bracket, and a winding device for winding up a sunshade sheet. A connecting shaft is provided protruding from one end of the mounting shaft, and either the mounting shaft or the connecting shaft is formed with a fitting recess that opens toward the outer circumference, and the other is formed into a prismatic shape to fit into the fitting recess. However, after the winding shaft is placed, the block is fixed with a bolt to seal the fitting recess so that the mounting shaft and the connecting shaft cannot be separated.

〔Example〕

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

What is shown in FIG. 4 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, and the middle 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 ends of the arms 3, 3 are placed outside the room. It is now possible to move in any direction. 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.
The leading end of the sunshade sheet 7 wound around the outer periphery of the winding shaft 6 is fixed to the front frame 4. As the bending angle of the arms 3, 3 increases, the front frame 4 protrudes toward the outdoors, and the sunshade sheet 7 is pulled out from the winding shaft 6. When the winding shaft 6 is rotated to wind up the sunshade sheet 7, the front frame 4 resists the spring force of the arms 3, 3.
retreats towards the building frame.

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. There is an operation box 9 in the mounting hole 8.
A circular fitting protrusion 10 protruding from one side of the case is fitted. The operation box 9 has a built-in worm gear, and when the hook 11 protruding downward is rotated, the mounting shaft 1 protrudes horizontally from the center of the fitting protrusion 10.
2 rotates. The mounting shaft 12 has a prismatic shape with a square cross section, and projects horizontally toward the other bracket 5. The mounting shaft 12 is not limited to a rectangular shape, but may have another polygonal shape. In this state, the bolt 8a, which is threaded so as to penetrate from the outer periphery of the bracket 5 into the mounting hole 8, is pressed against the fitting protrusion 10 of the operation box 9 and fixed.

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 connecting shaft 17 is protruded from one end of the winding shaft 6, and a fitting recess 18 with a U-shaped cross section that opens downward is formed in the connecting shaft 17, and the shaft body 1 is formed at the other end.
9 is provided protrudingly.

The shaft body 19 of this winding shaft 6 is attached to one bracket 5.
It is inserted into the shaft hole 16 of the bearing body 15 built in the upper part of the bracket 5, and the fitting recess 18 of the connecting shaft 17 at the other end is lowered from above to fit into the mounting shaft 12 protruding from the other bracket 5. Therefore, the connecting shaft 17 is the mounting shaft 1
2, and the winding shaft 6 is temporarily received between the brackets 5, 5.

Bolts 20, 20 are attached to the side of the connecting shaft 17 of the winding shaft 6.
This fixes the block 21, seals the fitting recess 18, and makes it impossible to remove the winding shaft 6.

This invention has the above-mentioned configuration, but the connecting shaft 17 of the winding shaft 6 is made into a prismatic shape, and a fitting recess 18 is formed in the mounting shaft 12 of the operation box 9, and the fitting recess 18 opens upward. The connecting shaft 17 may be fitted into the connecting shaft 17.

[Effect of idea]

This device has the above-mentioned configuration, and the operation box is fixed to one bracket, and an opening is opened toward the outer circumference on either one of the mounting shaft protruding toward the other bracket and the connecting shaft of the winding shaft. The winding shaft can be temporarily supported by fitting the other into the fitting recess, and then the block is fixed and the fitting recess is sealed, making it impossible to separate the mounting shaft and the connecting shaft.

Therefore, the winding shaft can be easily attached between the brackets by a single worker, and construction costs are reduced.
