Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a linear motor type curtain rail. Specifically, a cuttable part is provided at the end of the rail, and the curtain rail can be freely cut to fit the size of the window to which the curtain rail is attached. This article relates to the structure of a linear motor type curtain rail.

[Prior Art] The structure of a conventional linear motor type curtain rail is shown in a sectional view in FIG. 4 and an exploded perspective view in FIG. 5. The rail 1 has an inverted U-shaped cross section, and an inner rail 2 is fitted to the lower half of the inner surface of one side of the rail 1 over the entire length of the rail 1. A permanent magnet 3 and a yoke 4 are built-in. Similarly, a yoke 5 is provided on the other inner surface of the rail 1 along the entire length of the rail 1.
and a power supply pattern 6 are built in. Furthermore, a movable coil 8 is loosely fitted into the rail 1 so as to face the permanent magnet 3. The magnetic flux from the permanent magnet 3 always crosses this moving coil 8, and it receives electricity from the power supply pattern 6 via the power supply brush, so it moves within the rail 1 under thrust according to Fleming's left hand rule. do. A rail end 7 having a power supply terminal is fitted to the end of the rail 1, the power supply terminal is connected to the power supply pattern 6, and the rail end 7 is fixed with screws.

In this way, the conventional linear motor type curtain rail has the permanent magnet 3, yokes 4 and 5, power supply pattern 6, etc. built into the rail 1 over the entire range of the rail 1 that drives the motor. It was impossible to adjust the length of the rail 1 by cutting it to match the size of the window. Therefore,
Conventional linear motor type curtain rails have the inconvenience of having to be made as a special product with the length of the rail set according to conditions such as the size of the window to which it is installed. This is not so much of a problem in the case of limited uses such as vehicles, since the types are limited and mass-produced, so it is possible to set dimensions that correspond to the model, but for general housing. Although there are certain standards for the size of windows, there are actually a wide variety of sizes, and the installation locations and conditions vary, so a special window with a length set to suit each window is used. It was difficult to prepare supplies.

[Problems to be solved by the invention] As mentioned above, the invention solves the problem that it is impossible to shorten the end portion of the conventional linear motor type curtain rail to match the size of the window to which it is installed. This was done in view of the
By devising a linear motor-type curtain rail structure that can cut the end of the rail and making it possible to adjust the rail length, we were able to meet certain standards (for example, 3.
The aim is to provide standard rails based on the size of windows (shaku, 6 shaku, 9 shaku, etc.) to provide versatility that can be applied to a wide variety of windows in general homes, and to expand the range of applications.

[Means for Solving the Problems] The structure of the linear motor type curtain rail of the present invention includes a rail having an inverted U-shaped cross section, a flat permanent magnet attached to the inner surface of one side of the rail, and a curtain rail attached to the lower end of the rail. a movable coil that is loosely fitted into the rail so as to fix the runner and face the permanent magnet; a power supply pattern that is attached to the inner surface of the rail and feeds power to the movable coil; In the linear motor type curtain rail having a rail end having a power supply terminal connected to a power supply pattern, the permanent magnet built in the rail and the power supply pattern are shortened at the rail terminal part to form a rail cuttable part. and separating the rail end into the power supply terminal and the terminal cap,
The gist is that a wiring harness is extended from the terminal cap to the power supply terminal.

[Function] The linear motor type curtain rail of the present invention has a permanent magnet built into the rail, a power supply pattern, etc., shortened at the end of the rail, and a section where the rail can be cut is provided at the end of the rail, so it is easy to install. Depending on the size and mounting position of the window, the end of the rail can be cut to a desired length. In addition, since the rail end is separated into a power supply terminal and a terminal cap, the terminal cap is fitted and fixed at the end of the rail, the power supply terminal is attached to the shortened power supply pattern, and the terminal cap is attached to this power supply terminal. A wiring harness extending from the terminal to the power supply terminal is connected.

[Embodiment] A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention, showing a rail with imaginary lines. As shown in the cross-sectional view of Fig. 4, the rail 1 has an inverted U-shape in cross section.
The section from end point A of this rail 1 to point B of a predetermined length is a rail cuttable section 1a, and from the rail end point A of this rail cuttable section 1a to end B of rail cuttable section 1a, There is nothing built inside. The structure of the rail 1 from point B onward is exactly the same as that of a conventional linear motor type curtain, and the inner rail 2 is fitted into the lower half of the inner surface of one side of the rail 1 over the remaining entire length from point B onwards. A flat permanent magnet 3 and a yoke 4 are built into the inner rail 2. Similarly, a yoke 5 and a power supply pattern 6 are built into the other inner surface of the rail 1 over the remaining entire length of the rail 1 from point B. Also, rail 1
A movable coil 8 is loosely fitted inside the coil so as to face the permanent magnet 3. The magnetic flux from the permanent magnet 3 always crosses this moving coil 8, and it receives electricity from the power supply pattern 6 via the power supply brush, so it receives thrust according to Fleming's left hand rule, and moves inside the rail 1 through B. Move the remaining length beyond the point. Furthermore, curtain runners 12 are fixed to the lower ends of both sides of the movable coil 8.

A terminal cap 9 separated from the power supply terminal 10 is fitted to the terminal point A of the rail 1, and an insertion hole 9a for the wiring harness 14 passes through the center of the terminal cap 9. A fitting portion 9b of the coil stopper 11 is provided at the coil stopper 11.
The coil stopper 11 is a plate-shaped member that is slightly longer than the rail cuttable portion 1a, and one end 11a is fitted into the fitting portion 9b of the terminal cap 9, and the other end 11b protrudes into the rail 1 and moves within the rail 1. It is adapted to come into contact with the movable coil 8. A power supply terminal 10 separated from the terminal cap 9 is attached to point B of the rail 1 so as to be connected to the power supply pattern 6, and a wiring harness 14 inserted through the terminal cap 9 is attached to the power supply terminal 10. , are extended and connected inside the rail cuttable portion 1a.

Next, the installation and operation of the linear motor type curtain rail of this embodiment will be explained based on FIGS. 2A and 2B. FIG. 2 is a side view of a state in which the curtain 13 is hung on the curtain runner 12 and the curtain 13 is fully drawn to the end of the rail 1.
In FIG. 2, a certain amount of curtain accumulation L occurs between the terminal cap 9 and the movable coil 8 depending on the length of the curtain 13 (size of the window) and the number of curtain runners 12.

Figure 2A shows an example in which the rail 1 is attached without cutting it at all. In Fig. 2 A, the coil stopper 11
is slightly longer than the rail cuttable portion 1a, and the movable coil 8 comes into contact with the tip 11b of the coil stopper 11 and stops in accordance with the curtain accumulation amount L, so that when the rail 1 is not cut, the curtain 13 is fully opened at the position where the movable coil 8 is stopped by the coil stopper 11.

Now, the rail 1 is cut by a cutting amount l as shown in FIG. 2B. In addition, the cutting amount l of the rail 1 is
It is determined within the range of curtain accumulation amount L (l<
L). By cutting the rail 1 by a length l, the mounting position of the terminal cap 9 moves inward by l. Along with this, the coil stopper 11 is also
Therefore, the position of the movable coil 8 stopped by the coil stopper 11 also moves by l, and the curtain accumulation amount L does not change.
As a result, a linear motor type curtain rail that is shortened by the cutting amount 1 is completed.

Note that the curtain accumulation amount L is determined by the size of the curtain 13 (window size) and the number of curtain runners 12, so the larger the window curtain, the larger the curtain accumulation amount L.
The amount of cutting can be increased. That is,
For long rails, the rail cuttable portion 1a can be made long, so the power supply terminal 10 is placed as far inward as possible, and the length of the coil stopper 11 is made long enough to correspond to the curtain accumulation amount L, so that the movable coil 8 can be cut easily. All you have to do is move the stop position inward. Also,
As shown in Fig. 3A, this structure has a rail for double-opening curtains with cuttable sections 1a at both ends of the rail.
As shown in Figure 3B, for single-opening curtain rails, one end (curtain pool side)
What is necessary is to set the rail cuttable portion 1a at . In the former case, the sliding range of the moving coil 8 is between the terminal position 11b of one coil stopper 11 and the terminal position 11b of the other coil stopper 11, and in the latter case, the sliding range of the moving coil 8 is between the terminal position 11b of the coil stopper 11. Terminal position 11b and rail end 7 at the other end
It is between.

[Effects of the invention] As explained above, with the present invention, the conventional linear motor type curtain rail has permanent magnets, power supply patterns, yokes, etc. built into the rail, so it can be cut to fit the size of the window to be installed. This solves the problem of not being able to connect to the terminal cap, by shortening the built-in parts such as permanent magnets at the end of the rail, separating the end of the rail into the terminal cap and the power supply terminal, and extending the distance between the two. By connecting with a wiring harness, the end of the rail has a section that can be cut, and the end of the rail can be cut freely depending on the size of the window to be installed and the installation condition, so it is possible to cut the end of the rail according to certain standards. By preparing standard rails, it has the excellent effect of being able to accommodate a wide variety of windows in general homes.
