Curtain wave forming mechanism

Technical Field

The present invention relates to a curtain wave (wave) forming mechanism including a plurality of curtain movers attached to a curtain rail, and curtain hooks attached to the curtain movers and suspending a curtain.

Background

When the curtain is hung by the curtain hook with a large width vertically hung relative to the curtain mover, the curtain hook rotates integrally with the curtain without being against the curtain with a wave shape, so that the curtain forms a natural and beautiful curtain wave. For a curtain rail in which the pitch (maximum interval) of the curtain mover is defined, the curtain forms a wave having a circumferential length 2 times the pitch of the curtain hook, with the position of each curtain mover being a pitch.

A curtain hook having a flat shape and a large width for forming a wave in a curtain is disclosed in Japanese examined patent publication No. 5-2145. The curtain hook is integrated with the curtain belt, and the belt main body surface is bonded to a horizontally long mounting plate with an insertion hook at the upper edge at certain intervals. The insertion hook is vertically hung relative to the curtain mover, and the mounting plate is flat and wide, so that the hung curtain forms a natural and beautiful curtain wave.

However, since the conventional flat and wide insertion hooks are integrated with the curtain belt, the height of the curtain wave cannot be adjusted in the curtain rail in which the curtain mover pitch (maximum interval) is defined without replacing the curtain belt. Further, the conventional curtain mover cannot define the direction of the hook, and thus has a problem that the leading or trailing wave of the curtain is easily deformed. In addition, since the conventional flat and wide curtain hook is inserted, a general loop hook type curtain mover cannot be used.

Detailed Description

The curtain hook has a flat plate-like body part inserted into a hook hole part of the curtain belt, a foot part bent upward from the lower end of the body part and hooked to the hook hole, a shaft part extended from the upper end of the body part and having a front end formed as a thick head part, and an insertion head part or a ring hook provided at the front end of the shaft part.

Preferably, the longitudinal width of the curtain rail of the main body portion is greater than or equal to the diameter of the leg portion so that the curtain hook is rotated integrally with the curtain without being opposed to the curtain formed in a wave shape. In order to easily and reliably attach the curtain hook, it is preferable that the width of the foot portion is smaller than the width of the main body portion, a cutout portion having a larger width than the foot portion is provided in a portion of the main body portion facing the foot portion, and a protrusion is provided on the curtain side of the foot portion.

When the selection range of the curtain hook pitch is increased, the height of the curtain wave can be easily adjusted, and therefore, the interval width of the vertical arrangement of the curtain rails provided in the hook insertion holes of the curtain or the curtain belt is small.

Example 1

Example 1 is a curtain waveform forming mechanism including an insertion hook type curtain mover and an insertion hook, the head and tail of which are removed. Fig. 1 is a rear view of a main part of a window covering having a window covering waveform forming mechanism according to embodiment 1, and a dashed-dotted line in the figure shows a window covering fabric and a window covering tape. Fig. 2 is a side view of embodiment 1, and fig. 3 and 4 are a front view and a longitudinal sectional side view of an insertion hook.

As shown in fig. 1 and 2, the hook-inserted window curtain mover 1 includes: a main body 2, a cylinder body 3 supported on the main body 2 to be rotatable about a vertical axis and to be slidable up and down, and an insertion hook 4 inserted into the cylinder body 3 to be detachable from below. The main body 2 has wheels 5, and the vehicle travels in the curtain rail 6 by the wheels 5. The leg 7 of the main body 2 is suspended through the curtain rail 6, and the cylinder 3 is rotatably and vertically slidably attached to the cylinder support portion 8 of the leg 7. The upper half of the cylindrical body 3 is formed as a bearing 9 that opens and closes in the radial direction through an axial slit. When the head portion 10 of the insertion hook 4 is inserted into the cylindrical body 3 from below and the cylindrical body 3 is moved to the raised position, the bearing portion 9 is opened, and the inner diameter becomes larger than the head portion 10 of the insertion hook 4, so that the head portion 10 passes through the bearing portion 9. Therefore, when the insertion hook 4 is released and the cylinder body 3 returns to the lowered position, the bearing portion 9 is closed, the inner diameter becomes smaller than the head portion 10 of the insertion hook 4, and the bearing portion 9 supports the head portion 10 inserted therethrough from below.

As shown in fig. 3 and 4, the insertion hook 4 includes a flat plate-shaped body portion 11, a foot portion 12 bent upward from a lower end of the body portion 11, and a shaft portion 13 extending from an upper end center of the body portion and having a tip formed as a thick head portion 10. The foot portion 12 is smaller in width than the main body portion 11, and has a protrusion 14 on a surface facing the main body portion 11. A cutout portion 15 having a width larger than that of the foot portion 12 is provided in a portion of the main body portion 11 facing the foot portion 12, and a pin portion 16 is extended upward from both sides of the upper end portion.

As shown in fig. 1 and 2, the hooking hole 19 of the curtain tape 18 sewn to the curtain 17 is perpendicular to the longitudinal direction of the curtain rail 6, and the longitudinal width of the curtain rail is larger than the diameter of the leg portion 7 and is substantially the same as the main body portion 11 of the insertion hook 4. When the main body 11 of the insertion hook 4 is inserted into the through-hole 19 having substantially the same width and hooked on the foot 12, the position and posture of the insertion hook 4 are stabilized, and the head 10 is vertically protruded in the longitudinal direction with respect to the curtain rail. At this time, the foot 12 of the insertion hook 4 presses the curtain tape 18 into the cutout 15 of the main body 11, and the projection 14 bites into the curtain tape 18, so that the mutual displacement between the insertion hook 4 and the curtain tape 18 is restricted, and the posture and position of the head 10 of the insertion hook 4 are more stabilized. As a result, the operation of lifting up the curtain 17 together with the insertion hook 4, inserting the head 10 of the insertion hook 4 from below into the cylindrical body 3 of the curtain mover 1 attached to the curtain rail 6, and attaching the insertion hook 4 to the main body 2 is significantly easier than the operation in which the position and posture of the conventional insertion hook are unstable. The suspended curtain forms a natural, elegant wave. The circumference of the wave is determined by the interval of the part of the insertion hook hole 19 where the insertion hook 4 is attached.

Example 2

Example 2 is a curtain waveform forming mechanism including a front and rear insertion hook type curtain mover and an insertion hook. Fig. 5 is a front or rear view of a main part of a front or rear end portion of a window covering having a window covering waveform forming mechanism according to embodiment 2, in which a window covering fabric and a window covering tape are shown by a dashed-dotted line. FIG. 6 is a side view of example 2.

As shown in fig. 5 and 6, in example 2, the hook-inserted window shade mover 1a having the magnet-type attracting portion 20 suspends the leading end and the trailing end of the window shade. The main body 2a of the hook-inserted curtain mover 1a runs in the curtain rail 6 by 2 sets of wheels 5 a. The leg portion 7a hanging from the main body 2a is reinforced by the arm 22. The leg portion 7a has pin support portions 21 integrally formed on both sides orthogonal to the longitudinal direction of the lower curtain rail. The insertion hook 4 attached to the main body 2a from below is the same as in embodiment 1.

The pin support portion 21 is formed of 2 parallel flat plates extending from the leg portion 7a in the horizontal direction orthogonal to the longitudinal direction of the curtain rail, and when the 2 pin portions 16 of the insertion hook 4 are inserted between the 2 flat plates, the rotation of the insertion hook 4 is restricted, and the flat plate portion 11 of the insertion hook 4 is orthogonal to the longitudinal direction of the curtain rail 6. As a result, the leading end and the trailing end of the curtain 17 supported by the hook-inserted curtain mover 1a via the curtain tape 18 always form a large leading end wave and a large trailing end wave perpendicular to the longitudinal direction of the curtain rail 6. Thus, example 2 has a particular effect of forming a leading end or a trailing end wave having a large wave height at the curtain leading end or trailing end where the leading wave is attenuated. The configuration and effects other than those described above in embodiment 2 are exactly the same as those in embodiment 1.

Fig. 7 is a horizontal cross-sectional view of a window covering having the window covering wave forming mechanism of embodiment 1 at portions other than the head and tail portions and the window covering wave forming mechanism of embodiment 2 at the head and tail portions, taken along a window covering band.

A plurality of hook-inserted curtain movers are installed in a row in the curtain rail 6. The front and the end of the window shade are inserted hook type window shade movers 1a of the embodiment 2, and the middle of the window shade movers 1 are inserted hook type window shade movers 1 of the embodiment 1. A curtain 17, which is longer than the entire length of the rail, is suspended from the curtain rail 6. When the curtain 17 is deployed, the inserted hook-type curtain movers 1, 1a are arranged at equal intervals in the longitudinal direction of the curtain rail 6 by the maximum interval limiting means outside the figure, and the nodes and the wavelengths of the curtain waves are specified.

The insertion hooks 4 having the same number of large widths as the curtain movers 1, 1a in the curtain rail 6 are attached to the hook insertion holes of the curtain tape 18 along the upper edge of the curtain 17. The interval of the insertion hooks for determining the perimeter of each wave except the middle of the front end and the tail end is constant and is larger than the interval of the curtain mover when the curtain is unfolded. The insertion hook spacing for determining the wave circumference length of the leading and trailing ends is slightly larger than the insertion hook spacing in the middle.

The insertion hooks 4 are all located on the back side of the curtain 17 when viewed from the front. The respective insertion hooks 4 attached to the curtain mover 1 in the middle rotate integrally with the curtain 17 forming the wave, and the flat plate portions are alternately inclined sharply in opposite directions with respect to the longitudinal direction of the curtain rail. The insertion hooks 4 of the curtain mover 1a attached to the head and tail have flat plate portions perpendicular to the longitudinal direction of the curtain rail, and form head and tail waves that protrude perpendicularly to the front and have the same wave height as the intermediate wave at the head and tail portions of the curtain 17. As a result, the curtain 17 forms the same curtain wave from the head portion to the tail portion.

Example 3

Embodiment 3 is a curtain forming mechanism including a loop-hook type curtain mover and a loop hook. Force 8 and figure 9 are front and side views showing embodiment 3. As shown in the figure, the loop hook 4b of embodiment 3 is used for a known loop hook type window shade mover 1 b. The hook-and-loop type curtain mover 1b includes a body 2b that runs in the curtain rail, a leg portion 7b of the body 2b that hangs down from the curtain rail, a cylindrical body 3b that is supported on the leg portion 7b so as to be rotatable about a vertical axis, and a loop 23 that is supported on the cylindrical body 3 b. The front end of the shaft portion 13 of the loop hook 4b forms a hook 24. The hook 24 is hooked to the ring 23 of the ring-and-hook type curtain mover 1 b. The configuration and effects other than the above are the same as those of embodiment 1.
