Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a Roman shade cord winding member.

[Prior art and its problems] Conventionally, a cord for raising and lowering a Roman shade is wound around a shaft provided on a Roman shade support, or is attached to a Roman shade support via a guide member. It is operated by guiding it along one end of the support material. The former method of winding the cord around the shaft of a cord winding member installed on a Roman shade support material is conventionally divided into two cases: one in which the cord winding member is placed outside the support, and the other in which it is placed inside the support. . When disposed outside, installation is easy and adjustment is easy, but there is a problem in that lateral force is applied to the support member, making it easy to break down. On the other hand, when it is installed inside, the load is applied directly under the support member, so it is less likely to break down, but there are problems in that it is troublesome to install and difficult to adjust. When disposed inside the support material, conventional cord winding members do not have a cord guide opening or have a structure such as a round shape that prevents the cord from coming off even if there is a cord guide opening, and the first stage of the first winding is aligned. There was no intention of winding the cord, and the cord was wound randomly, and in the worst case, the cord could fly out from the edge of the drum.Generally, the drum was set to be large, making it look larger.

The present invention solves the above problems and allows the cords to be wound in line on the drum, and a large number of cords can be stored.The cord winding member can be made smaller, and the cords are not tangled. To provide a Roman shade cord winding member in which the shade is evenly raised and lowered because the shade is stored uniformly without any problems.

[Means for Solving the Problems] In order to solve the above problems and achieve the object of the invention, the Roman shade cord winding member according to the invention is characterized by having the following structure. In other words, the first idea is to provide a cord guiding port which is attached to the inside of the brim of the cord drum and which locks one end of the cord in contact with the brim, and which is located inward from the inner width of the code drum by the thickness of the cord. The second aspect of the invention is that one end of the cord is secured to the inside of the collar of the cord drum in contact with the collar, and the cord guide opening provided in the cord drum is provided with a cord that is connected to the cord in the axial direction of the cord drum. A shaft is provided in the same direction, and a guide roller is provided on the shaft, and the guide roller can slide in the axial direction of the shaft with sliding friction, and the sliding range is within the range where the cord is wider than the inner width of the cord drum. The guide roller flange is characterized by forming a small gap between the guide roller flange and the guide port wall.

[Example] The present invention will be explained in detail below using an example shown in the drawings. Fig. 1 is a front view of the first embodiment, Fig. 2 is a right side view of the same, Fig. 3 is a plan view of the same, Fig. 4 is a bottom view of the same, and Fig. 5 is a front view of the second embodiment. 6 is a bottom view of the same, and FIG. 7 is a sectional view taken along the line A-A in FIG. 5.
Here, 1 is a cord drum, 11 is a collar, 2 is a cord, 21 is a cord locking part, 3 is a cord guide port,
31 is a guide port wall, 4 is a shaft, 5 is a guide roller, 51
52 indicates a guide roller flange, and 52 indicates a guide port wall.

In the first embodiment of the Roman shade cord winding member, one end of the cord 2 is locked inside the collar 11 of the cord drum 1 in contact with the collar 11. FIG. 3 shows the cord locking portion 21.

The cord guide opening 3 is located at the inner width of the cord drum 1, that is, at the flanges 1 provided at both ends of the cord drum 1.
1, each cord 2 is opened inward by the thickness of the cord 2. FIG. 3 shows the cord guide port 3 in an open state.

Since the first embodiment of the Roman Shade cord winding member is constructed as described above, when it is disposed inside the support member and used, the first winding of the first stage on the cord winding is at the brim 11. The second winding is wound in contact with the end of the cord guide port 3, so the second winding is wound in tandem with the first winding, and from then on, the cord is wound in line with the first winding. The other collar 11 of the cord drum 1 is wound sequentially using the cord as a guide.
The second and subsequent stages are similarly aligned and wound.

In the second embodiment of the Roman shade cord winding member, one end of the cord 2 is secured inside the collar 11 of the cord drum 1 in contact with the collar 11, as shown in FIG.

In the cord guide port 3 provided in the cord drum 1,
A shaft 4 is provided in the same direction as the axial direction of the code drum 1, and a guide roller 5 is provided on the shaft 4.

The guide roller 5 can slide in the axial direction of the shaft 4 with sliding friction, and its sliding range is within code 2.
are inward from the inner width of the cord drum 1 by the thickness of the cord 2, and the guide roller flange 51 and the guide port wall 52 form a slight gap.

The second embodiment of the Roman Shade cord winding member is constructed as described above, so when it is disposed inside the support member and used, the first winding of the first stage on the cord winding is at the brim 11. The next second roll is guided by the guide roller 5, so the second roll is wound in contact with the
The windings are wound in tandem with the first winding, and thereafter they are wound in sequence using the previously wound cord as a guide until they are wound up to the other collar 11 of the cord drum 1, and the same goes for the second and subsequent stages. are lined up and wound. At this time, since the guide roller flange 51 and the guide port wall 52 form a small gap, the cord 2 does not come off from the guide roller flange 51. Also,
The guide roller can slide in the axial direction of the shaft with sliding friction, so the sliding friction force at the time of thrust winds the cord in an aligned manner, and the lateral stress is balanced with the cord so that it is densely lined up and the lower stages from the second stage onwards. Eliminate variations in penetration.

[Effects of the invention] Since the Roman shade cord winding member according to the invention is configured as described above, the cords can be wound in alignment on the drum, and a large number of cords can be stored. As a result, the cord winding member can be made smaller, and since the cords are evenly stored without being tangled, the shade can be raised and lowered uniformly.
