Description

[Detailed Description of the Invention] The present invention relates to a radiator curtain that is installed in front of a radiator of an automobile, and its purpose is to reduce the weight of an automatic curtain winding device and to provide it at low cost.

As shown in FIGS. 1 and 2, the radiator curtain is installed in front of the radiator of automobile A, and covers the radiator when the outside temperature is low, such as in winter, to prevent the radiator from overcooling. When the curtain is not in use, such as during the summer, the curtain is wound up by an automatic winding device.

In conventional automatic winding devices, the winding roll is made of a cylindrical iron plate, and the shaft that runs vertically through the center of the roll to rotatably hold the roll is one long metal shaft. Furthermore, the bushings fitted at several locations within the roll to support the shaft were also die-cast metal products. Therefore, the automatic winding device made up of the above-mentioned parts is quite heavy.
Since the rollers are installed in areas exposed to rainwater or car wash water, the rolls tend to rust, which is undesirable in terms of appearance. Furthermore, there were also problems with high manufacturing costs.

In addition, the curtain wound around the outer periphery of the roll is connected to the outer periphery of the roll and the end of the curtain, but in this case, a groove-shaped recess is provided in the axial direction of the outer peripheral surface of the roll, and the recess is A connecting member made of resin molded material such as vinyl chloride with iron wire sandwiched therein was fitted, and the end of the curtain was connected to the connecting member by sewing or the like. Therefore, it was very time-consuming to manufacture.

The present invention provides a radiator curtain that solves all of the above-mentioned conventional problems, and examples thereof will be described below with reference to FIGS. 3 and 4.

1 is a roll for winding up the curtain. This roll 1 is made of synthetic resin and is molded into a cylindrical shape. Bushes 2a and 2b are fitted onto both ends of the roll 1 and fixed to the roll 1 with screws or the like. Further, 2c is a bush fitted approximately in the center of the roll 1 and capable of sliding left and right within the roll 1. These bushes 2a, 2b, and 2c are all press-formed from iron plates.

The bushes 2 are fitted to both ends of the roll 1.
Short shafts 3a, 3b are inserted and supported in the rolls 1a, 2b. The shaft 3a is restricted in its axial movement by a stopper ring 4. The short shafts 3a, 3b at both ends are connected together by a pipe 5 inserted and supported in a bush 2c in the approximate center of the roll 1. One end of a coil spring 6 wound around the outer periphery of the pipe 5 is hooked to the pipe 5, and the other end is hooked to the bush 2c, so that the roll 1 is supported by the pipe 5.
A rotational force in the winding direction is applied to the winding roller.

Furthermore, in the axial direction of the outer circumferential surface of the roll 1, a fourth
As shown in the figure, a bay-shaped arcuate groove 10 is provided. Further, a connecting member 8 having a beaded edge 9 is attached to the upper end of the curtain 7 made of leather or the like by sewing or the like. This connecting member 8 is made of a synthetic resin molded product, and the bead 9 is inserted into and engaged with an arcuate groove 10 provided on the outer peripheral surface of the roll 1, and the curtain 7 is connected to the roll through this connecting member 8. 1.

A bar 11 and a band 12 are attached to the lower end of the curtain 7. The band 12 is used to hang the curtain 7 on a hook (not shown) when the curtain 7 is pulled out, and the bar 11 is used to prevent the curtain 7 from sagging. Conventionally, this bar 11 is a rod-shaped object made of iron, but in the present invention, an iron plate is bent by a press to maintain rigidity and reduce weight.

Since the present invention is as described above, shaft 3
The roll 1 is rotatably held by fixing a and 3b to a fixed portion in front of the radiator. Further, the curtain 7 is normally rolled up on the outer peripheral surface of the roll 1 (when not in use). Therefore, when covering the front of the radiator, by pulling down the band 12, the curtain 7 wound around the roll 1 is pulled out.
At this time, the roll 1 rotates to accumulate a restoring force in the spring 6 and apply a rotational force to the roll 1 in the winding direction. Therefore, when storing the curtain 7, the band 12 is removed from the hook, and the curtain 7 is automatically wound onto the roll 1.

Therefore, the present invention has the advantage of being able to provide a low-cost radiator curtain that is lightweight and free from rust problems. In other words, the roll is a cylindrical synthetic resin molded product, the bush is a press molded steel plate instead of a die-cast molded product, and the shaft is a pair of short shafts that are connected together with a pipe, which accounts for most of the weight. The automatic winding device can be greatly reduced in weight, and material costs and manufacturing costs can be significantly reduced. Furthermore, since the connecting member between the curtain and the roll has a beaded structure made of a synthetic resin molded product, there is no need to insert iron wires as in the conventional method, and the manufacturing is simple, lightweight, and inexpensive.
