1 is a perspective view showing a stepless roller blind according to an embodiment of the present invention; and FIGS. 2a to 2c are cross-sectional views showing a segmentless roller blind according to an embodiment of the present invention; FIG. 3a to Fig. 3c is a cross-sectional view showing a stepless roller blind according to another embodiment of the present creation; and Fig. 4 is an exploded view showing the force member of the segmentless roller blind according to the embodiment of the present invention.

Referring to FIGS. 1 through 4, a stepless roller blind 100 according to an embodiment of the present invention includes a cord 1, a reel mechanism 2, and a brake mechanism 3. The cord 1 is attached to the reel mechanism 2 and can be retracted onto or unrolled from the reel mechanism 2. The brake mechanism 3 is provided to the reel mechanism 2 for braking the curtain 1 to position the curtain 1.

The reel mechanism 2 includes a reel seat 21 and a winding member 22. The reel seat 21 includes a reel 211 and a sleeve 212 that is coupled to the reel 211 and linked. The cord 1 is attached to the spool 211 and can be wound around the spool seat 21 or unfolded from the spool seat 21 along a cord passage path P1. The rolling force member 22 includes a coil spring member 221, and the coil spring member 221 is sleeved on the reel seat 21. The torsion F2 of the coil spring member 221 drives the reel seat 21 to rotate in a fixed rotational direction, so that the reel seat 21 is normally in a retracting motion for retracting the cord 1 on the reel seat 21. By applying a deployment force F1 to the cord 1, the user can unfold the cord 1 from the reel seat 21 along the cord through the path P1, and after releasing the cord 1, the coil spring member 221 will drive the reel seat 21 to rotate automatically. Roll up the curtain 1. The cord passage path P1 means a path through which the cord 1 passes when unfolded or retracted. Further, the front portion of the cord 1 preferably has a head restraint 11 for limiting the position, so that a portion of the cord 1 remains retained outside the casing 20 of the reel mechanism 2 after being retracted so as not to be completely caught in the reel seat 21. The housing 20 is for mounting on a window or other fixture, preferably having mounting holes 201 on each side, and can be mounted on either side as appropriate.

The brake mechanism 3 is located on the side of the reel seat 21 (which is also the curtain passage path P1) and includes a shifting member 31 and a brake member 32. In this embodiment, the shifting member 31 includes a slide rail 311 and a slide bar 312 disposed on the slide rail 311. The slide bar 312 is disposed to slide along the slide rail 311 to be relatively close to or away from the reel seat 21 (the curtain 1). The brake member 32 is disposed on the side of the slide bar 312 adjacent to the reel seat 21, and is pressed against the reel seat when the slide bar 312 slides toward the reel seat 21 (this shifting action is called the lock transfer S2 of the shifting member 31). 21, and braking the roller holder 21 and the curtain 1 by friction, and when the slider 312 slides away from the roller holder 21 (this movement is called the release swing S1 of the shifting member 31), the stopper 32 is released and released. Reel seat 21 and curtain 1.

The sliding direction of the slide bar 312 in the release swing S1 is the forward direction of the deployment direction D1 of the curtain 1, in other words, the winding direction D2 of the curtain 1 and the swinging direction of the slide bar 312 in the locking shift S2 are forward. . Specifically, such an arrangement is such that when the cord 1 is unfolded, the shifting member 31 is driven by the reel seat 21 or the cord 1 to release the swing S1, and the retaining member 32 is moved away to release the reel seat 21 and the cord 1 (as shown in FIG. 2a). Shown). When the cord 1 is wound up, the swinging member 31 is driven by the reel seat 21 or the cord 1 to lock the swing S2, so that the brake member 32 presses against and brakes the reel seat 21 and the curtain 1 (as shown in FIG. 2b). Shown). With such a structure, the cord 1 is hardly subjected to the resistance of the stopper 32 during the unfolding, and after the pulling of the cord 1 is stopped, the braking of the stopper 32 prevents the cord 1 from being caught, and the curtain 1 is positioned at the present. Expanded position.

In the present embodiment, the shifting member 31 is further coupled with a biasing member 33. The biasing member 33 is, for example, a spring that is elastically disposed between the shifting member 31 and the housing 20. The biasing member 33 pushes the sliding rod 312 toward the reel seat 21 (and the curtain 1), and the normal state causes the moving member 31 to drive the braking member 32 to the locking swing S2, which causes the braking member 32 to be immediately released as long as the deployment of the curtain 1 is stopped. The brake cord 1 is positioned therewith.

The shifting member 31 is preferably further connected to a release member 34. The release member 34 is, for example, a pull member that is operated by a pulling force F3 to drive the shifting member 31 to release the swing S1. By operating the release member 34 to keep the shifting member 31 in the state of releasing the swing S1, the cord 1 is automatically taken up by the torsion force F2 of the wind force member 22 to be retracted onto the reel seat 21.

The brake mechanism 3 can also be another structure. For example, in a stepless roller blind 100a of another embodiment shown in Figs. 3a to 3c, the shifting member 31a of the brake mechanism 3 includes a rotating shaft 311a and a connecting shaft. A rotating arm 312a of 311a. The brake member 32 is coupled to the rotating arm 312a, and the rotating arm 312a is disposed to be in a forward direction with respect to the swinging direction of the release swing S1 and the unfolding direction D1 of the cord 1. Specifically, when the cord 1 is unfolded, the swinging member 31a is driven by the reel seat 21 or the cord 1 to release the swing S1, so that the stopper 32 is moved away to release the reel seat 21 and the cord 1 (as shown in FIG. 3a). . When the cord 1 is wound up, the swinging member 31a is driven by the spool seat 21 or the cord 1 to lock the swing S2, so that the stopper 32 presses against and brakes the spool seat 21 and the curtain 1 (as shown in Fig. 3b). In this embodiment, a release member 34a is provided at a corresponding position of the swaying member 31a. The release member 34a is a urging member that is urged by a pushing force F4 to urge the swaying member 31a to release the yaw S1. By operating the release member 34a to keep the shifting member 31a in the state of releasing the swing S1, the cord 1 is automatically retracted on the reel seat 21 by the torsion F2 of the wind force member 22. It should be noted that in this embodiment, the biasing member may not be provided, and the swinging member 31a can be automatically moved back to the equilibrium position by gravity.

In addition, in order to adjust the winding or unwinding speed of the cord 1, the stepless roller blind 100 may further include a retracting force control member 4. The accommodating force control member 4 is disposed on one side of the reel seat 21 or the cord passing path P1, and the tightness is adjustably pressed against the reel seat 21 or the cord 1. The retractable force control member 4 is, for example, a screw member that is bored on the casing 20 and has one end facing the reel seat 21 (the curtain 1). The tightness of the adjusting screw member can change the frictional force between the screw member and the reel seat 21, and the winding speed of the cord 1 can be slowed down by increasing the frictional force.

In addition, in order to adjust the torsion F2 of the take-up cord 1, the wind force member 22 includes a torque adjusting member 222 and a fixing seat 223 in addition to the coil spring member 221 in this embodiment, and the torque adjusting member 222 has a selected twist angle. The coil spring member 221 is connected to be fastened to the fixing seat 223. In detail, the torsion adjusting member 222 includes a spring frame 222a and a buckle portion 222b. The coil spring member 221 is wound around the spring holder 222a and connected to the reel seat 21, and the degree of winding deformation of the coil spring member 221 determines the torque it provides to the reel seat 21. The fixing base 223 has a plurality of adjusting grooves 224. The multi-stage adjustment groove 224 has a plurality of positioning groove portions 225 at different torsion angle positions. The multi-stage adjustment groove 224 is a square groove in this embodiment, and has a positioning groove portion 225 at four right-angle positions. Therefore, the buckle portion 222b can be correspondingly buckled on the positioning groove portion 225 at an arbitrary selected twist angle of a multiple of 90 degrees to determine the magnitude of the torsion F2 provided by the coil spring member 221 to the reel seat 21. With this configuration, it is possible to easily adjust the force of the take-up cord 1 of the reel seat 21 at any time, and it is possible to quickly solve the problem of insufficient returning torque caused by factors such as spring elastic fatigue.

The above description is only for the preferred embodiment of the present invention, and those skilled in the art can make other improvements according to the above description, but these changes still belong to the creative spirit of the creation and the patents defined below. In the scope.
