Slider mechanism for blinds and slider system with gear clutch flip mechanism

technical field

The invention relates to a shutter accessory, in particular to a shutter mechanism and a slider system composed of the slider mechanism and a gear clutch overturning mechanism.

Background technique

The traditional blinds are composed of louver blades with an arc-shaped cross section, lift ropes, ladder belts, top rails and bottom rails. A rotary drive with self-locking function, a rotating shaft, and several winding lifts are installed in the top rail. The rope and the reel of the ladder belt are controlled. The rotating shaft passes through the rotary driver and the reel. A ladder belt is arranged between the top rail and the bottom rail. The lower end of the ladder belt is fixedly connected with the bottom rail. On the reel, a plurality of louvers arranged in parallel are worn in the horizontal cable of the ladder belt. A perforation is set at the symmetrical center of the cross section of the louver to allow the lifting rope to pass through. The lower end of the lifting rope is fixedly connected with the bottom rail. The upper end is wound on the reel; the rotating shaft and the reel are driven by the rotating drive, and the louver can be lifted and turned over. When the louver is folded, the lifting rope is wound to drive the bottom rail to rise, so that the louver is lifted up in turn. When the louvers are put down, the lifting rope is relaxed. Under the gravity of the bottom rail, the louvers move down one by one and are placed equidistantly by the horizontal cables of the ladder belt. When the bottom rail reaches the window sill, the lifting rope is finished and continues When the rotary drive is pulled, the reel rotating together with the rotating shaft will flip the louvers through the action of friction to achieve the effect of indoor dimming. In actual situations, the reel used to wind the lifting rope can also be replaced by a screw (see utility model ZL02201583.3, utility model ZL200420078400.6, invention patent application number: 200480014523.6), and the ladder belt is driven to rotate by friction or bayonet The reel wheel can also be replaced by a torsion spring or a spring wheel (see invention patent application number: 200480014523.6).

A fatal flaw of traditional blinds is that the indoor daylight illumination cannot be uniform. If the louvers are turned over and adjusted to moderate light near the windows without glare, then the illuminance in the deep part of the room is not enough and artificial lighting is needed. In addition, in summer, people only need moderate light but not heat, and in winter, people need both moderate light and heat. In order to reduce the light and heat near the window, traditional blinds must be closed no matter in summer or winter. The louver blades are flipped to the degree that they are almost closed, which causes the entire room to be too dark, so that whether it is a sunny day or a cloudy day, artificial lighting must be used to maintain an appropriate indoor lighting level, which will cause a lot of energy to be wasted, and Also reduce people's sense of comfort and work efficiency. Therefore, in order to prevent glare and overheating near the windows, and to obtain uniform daylight illumination deep in the room, the Chinese invention patent application (application number: 201010162501.1 and application number: 201010620508.3) discloses two kinds of louvers with combined structure, The combined louvers made of this kind of combined louvers will not change the light path irradiated on the louvers no matter the sun altitude angle H is greater than or smaller than the shading angle of the louvers, so as to meet the requirements of preventing glare and overheating near the windows. Requirements, but also meet the requirements of uniform daylight lighting deep in the room. At the same time, it does not affect the indoor and outdoor visual communication and air flow. However, this invention patent application only discloses the combined structure of the combined louver and the sunshade and light guide effect of the relative lifting and turning of the louver, and does not disclose the transmission mechanism related to the combined louver.

The present invention discloses a roller system for the above shutter. This reel system is also suitable for the new combined blind scheme with more than three secondary louver blades expanded from the above-mentioned inventions (201010162501.1 and 201010620508.3).

Driven by the hollow screw rod 3651 of the gear 365, it slides axially until the first slide block 351 starts to contact the second slide block 352, and the front and rear cables 811 and 812 of the next ladder belt 81 of the next hundred blades 91 are moved by the next slide block 351. The slider 351 slides in an axial direction, so that the sub-100th blade 91 leaves the overlapping position with the sub-200th blade 92 and rises _D1 - _D2 horizontally relative to the main louver 90. At this time, the sub-2nd slider 352, The third slider 353 is not moving (as shown in Figure 30b), and the flip cylinder 354 and the flip disc 362 are locked on the fixed sleeve 361 by the torsion spring 363; After the contact, the rotating shaft 356 continues to rotate with the clutch gear 365 and moves axially forward. When the next slider 351 presses the second slider 352 and pushes the second slider 352 to slide to the contact position with the third slider 353, The front and rear cables 811 and 812 of the second ladder belt 81 of the next one hundred blades 91 are pulled by the next slide block 351 to slide axially together, and the front and rear cables 821 and the rear cables 821 of the second second ladder belt 82 of the second two hundred blades 92 822 is pulled by the second slider 352 to slide in an axial direction, so that the second 200 blade 92 leaves the overlapping position with the second 300 blade 93 and rises horizontally with the second 100 blade 91 relative to the main louver 90 D ₂ - D ₃ height, at this time the second third slider 353 is not moving (as shown in Figure 30c); the second second slider 352 is pressed against the second second slider 352 by the second first slider 351 and the second second slider 352 is pushed to slide axially, and the second second slider 352 When pressing the second third slider 353 and pushing the second third slider 353 to slide axially until it contacts with the support 386 of the base 38 (as shown in Figure 19), the front and rear of the second ladder belt 81 of the second hundredth blade 91 Back cables 811 and 812 are pulled by the next slide block 351 to slide, and the front and rear cables 821 and 822 of the second second ladder belt 82 of the second two hundred blades 92 are pulled by the second slide block 352 to slide, and the second three hundred blades 93 The front and rear cables 831 and 832 of the second third ladder belt 83 are pulled and slid by the second third slide block 353, so that the second three louver blades 93 leave the overlapping position with the main louver blade 90 and merge with the second one hundred blades 91 and the second two hundred The blades 92 rise horizontally by a height of D3 relative to the main louver ₉₀ (as shown in Figure 30d); when the rotating shaft 356 drives the next slider 351 to slide, it also drives the clutch gear 365 to rotate, and the clutch gear 365 rotates due to Constrained by the thread of the fixed nut 366, it moves axially at a speed of one pitch per revolution. The initial axial distance between the clutch gear 365 and the torsion spring unlocking gear 364 is D ₁ (as shown in Figure 20), and its size depends on The screw pitch of the fixing nut 366 and the maximum distance D ₁ of the rise of the secondary 100th blade 91 relative to the main louver 90 slide to the support 386 with the base 38 on the secondary 3rd slider 353 When in contact with each other (as shown in Figure 19), the clutch gear 365 also begins to insert into the torsion spring unlocking gear 364 and meshes with it (as shown in Figure 21). When the rotating shaft 356 continues to rotate, the clutch gear 365 gradually inserts into the torsion spring unlocking gear 364 and The torsion spring unlocking gear 364 is driven to rotate together, and the side wall 3645 of the semi-circular wall 3644 of the torsion spring unlocking gear 364 is pressed onto one end 3631 of the torsion spring 363, releasing the locking effect of the torsion spring 363 on the turning disc 362 and pushing the turning disc 362 and drive the third slider 353, the second slider 352, the first slider 351 and the turning cylinder 354 through the slider 357 to rotate the shutter closing angle in the same direction until the sliding rod 357 contacts the support 386 of the base 38 (as shown in Figure 25), thereby driving the main and secondary louvers 9 to turn over

to the closed position (as shown in Figure 30e); the relative rise is completed at the secondary louver blades 91, 92 and 93, and together with the main louver blade 90, the flip plate 362, the first slider 351, the second slider 352, and the third slider After the block 353 and the turning cylinder 354 turn over to the closed position, the anti-rotation shaft 356 makes the main and secondary louvers 9 retreat in the original order, that is, firstly, the main and secondary louvers 9 turn over to the horizontal position as shown in Figure 30d at the same time. When the main and secondary louver blades 9 are flipped to the horizontal position, the clutch gear 365 gradually withdraws from the torsion spring unlocking gear 364, but still drives the torsion spring unlocking gear 364 to reverse, and the side wall of the semi-circular wall 3644 of the torsion spring unlocking gear 364 3645 is pressed on one end 3532 of torsion spring 363, releases the locking action of torsion spring 363 to flipping disc 362 and drives the second slide block 351, the second slide block 352, the third slide block 353 and the flip cylinder 354 through the slide bar 357. Each ladder belt drives the main and secondary louver 9 to flip in reverse through the slider and the turning cylinder. When the main and secondary louver 9 returns to the initial horizontal position (as shown in Figure 30d), the clutch gear 365 and the torsion spring unlocking gear 364 disengages, the flip disc 362 and the flip barrel 354 are locked on the fixed sleeve 361 by the torsion spring, and the rotating shaft 356 continues to rotate in the reverse direction, the clutch gear 365 retracts axially, and the hollow screw 3561 drives the next slide block 351 to retract axially synchronously. The interaction between the first slider 351 and the second slider 352 is released, and the interaction between the second slider 352 and the third slider 353 is released. Descending in the original order, when the third slider 353 axially retreats and is blocked by the projection 385 of the base 38, the second three hundred blades 93 are superimposed on the main louver blades 90, the second one hundred blades 91 and the second two hundred blades 92 The distance _D3 is lowered relative to the main louver 90 (as shown in FIG. 30c ). Blocked by it (as shown in Figure 22 and Figure 23), when the second slider 352 axially retracts and is blocked by the protrusion 384 of the base 38, the second two hundred blades 92 are superimposed on the second three hundred blades 93, and the second one The louver 91 and the second louver 92 have descended a distance of D ₂ -D ₃ relative to the main louver 90 (as shown in Figure 30b ), during which the bottom notch 3513 of the second slider 351 is higher than the projection of the base 38 384 without being blocked by it (as shown in Figure 22), when the axial retreat of the next slider 351 is blocked by the turning cylinder 354, the next one hundred blades 91 are superimposed on the second two hundred blades 92, and the next one hundred blades 91 The distance D ₁ -D ₂ is lowered relative to the main louver 90 (as shown in FIG. 30 a ).
