Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a sheet shutter that is used in combination with a normal shutter or used alone for interior decoration.

(Prior Art) As shown in FIG. 3, this type of sheet shutter has guide pieces 3 protruding from both side edges of the sheet 1 at predetermined intervals in the length direction, and the tips of the guide pieces 3. The engaging member 4 attached to the guide rail 8 is inserted into the guide rail 8 so that it can be raised and lowered while being locked to the vertical rail portion 9 in the guide rail 8. The seat 1 is moved up and down by the wind or the like and the guide rail 8 It prevents it from coming off.

Conventionally, such an engaging member 4 has a vertical cylinder part 12 with a core material 11 inside the guide piece 3 formed at the tip of the guide piece 3 as shown in FIGS. As shown, a structure in which rollers 14, 14 are fixed with rivets 15 or the like is employed.

(Problem to be Solved by the Invention) However, according to the former engaging member 4, when the seat 1 is raised or lowered, the seat 1 is agitated by the influence of wind etc., and the engagement with the vertical rail portion 9 of the guide rail 8 is caused. When the sliding locking force of the member 4 becomes large, the engaging member 4 cannot follow the lifting speed of the seat 1, and the guide piece 3 is bent and deformed as shown in FIG. Not only was this not done smoothly, but there was a risk of damage at the connection to the sheet 1.

On the other hand, according to the latter engagement member 4, the guide piece 3
The tensile strength of the guide piece 3 is only the strength of the base material of the guide piece 3, which corresponds to the diameter of the rivet 15, and the guide piece 3 will be damaged in a short period of time from the rivet 15, and if the tightening force by the rivet 15 is increased, the rotation of the roller 14 will be prevented. There was a risk that the guide piece 3 would be blocked and the guide piece 3 would be damaged.

The present invention provides a sheet shutter that solves these problems.

(Means for Solving the Problems) As shown in the drawings corresponding to the embodiments, the seat shutter of the present invention has guide pieces 3 for the guide rail protruding from both side edges at appropriate intervals. In the seat shutter, an engaging member 4 that engages with the vertical rail portion of the guide rail is attached to the tip of the guide piece 3. The trochanters 7, 7 are attached to the spacers 6, 6 through the wide-brimmed spacers 6, 6, and the inner surfaces of the trochanters are pressed against the outer surfaces of the spacers 6, 6.
This is characterized in that the guide piece 3 is crimped onto both sides of the guide piece 3.

(Function) Since the trochanter 7 is attached to the guide piece 3 via the spacer 6, it rotates smoothly and follows the rise and fall of the seat 1 even if it is strongly engaged with the vertical rail portion of the guide rail. Moreover, since the spacer 6 is crimped and integrated with the guide piece 3, the tensile strength of the guide piece 3 is increased.

(Example) To explain the example of the present invention with reference to the drawings, 1
is a sheet main body made of cloth or a flexible synthetic resin sheet, etc., and on both side edges thereof, at appropriate intervals in the length direction, oblong rectangular shapes made of the same material as the sheet main body 1 or pieces of flexible cloth with high strength are formed. A pair of guide pieces 3 are attached thereto, and an engaging member 4 that engages with a vertical rail portion 9 of a guide rail 8 is attached to the tip end of each guide piece 3.

This engaging member 4 has a pin 5 passed through the tip of the guide piece 3, and a pair of wide-brimmed spacers 6, 6 fitted onto the pin 5 so as to sandwich the guide piece 3. , 6 are crimped to both sides of the guide piece 3, and trochanters 7, 7 made of bearings are attached to the outer end of the pin 5 on the outside of the spacer 6, and the inner race of the trochanter 7 The trochanter 7 is configured to be freely rotatable with its portion pressed against the outer surface of the spacer 6.

The guide rail 8 for raising and lowering the seat configured in this manner is made of a U-shaped cross section with an opening 2 extending over its entire length on the front surface, and has a pair of left and right vertical rail sections on the inner surfaces of the opposite side walls inside the guide rail 8. 9, 9 are fixed over the entire length. In addition, the vertical rail portion 9,
A guide piece insertion interval 10 having a width through which the guide piece 3 can be inserted is provided between the guide pieces 9 over the entire length.

The guide rails 8, 8 are attached to the inner wall of an opening such as an entrance/exit, and are disposed above the winding drum 16 to wind the sheet main body 1. When in use, the winding drum 16 is rewound to roll the sheet main body 1. When lowered, the guide pieces 3 provided on both side edges of the sheet main body 1 are inserted from the upper end opening of the guide rail 8 into the space 10 between the vertical rail parts 9, 9, and the trochanters 7, 7 are vertically While being locked to the back surfaces of the rail portions 9, 9, they are successively suspended and closed, and will not come off the guide rails 8, 8 even if blown by the wind or the like.

(Effect of the invention) As described above, according to the seat shutter of the invention, the engaging member 4 attached to the tip of the guide piece 3 attached to both side edges of the seat main body 1 is A pin 5 is inserted into the tip, a trochanter 7, 7 is attached to the pin 5 via a wide-brimmed spacer 6, 6, and the inner surface of the trochanter is pressed against the outer surface of the spacer 6, 6. Since the spacers 6, 6 are crimped onto both sides of the guide piece 3, the trochanters 7, 7, which are engaged with the vertical rail portion 9 of the guide rail 8, are attached to the guide piece 3 via the spacers 6, 6. 3, the trochanter 7 can be easily rotated and moves smoothly following the rising and lowering speed of the seat while being locked to the vertical rail part 9, thereby preventing excessive tensile force from being applied to the guide piece 3. This allows the seat to be moved up and down easily over a long period of time without causing any problems.

In addition, since the spacer 6 is formed with a wide brim and the guide piece 3 is integrally crimped, the contact area of the guide piece 3 is increased to prevent damage, and the strength of the mounting part is also increased, making it strong. Therefore, it can withstand long-term use.
