Description

Magic shade

The present invention relates to a curtain installed in a vertical direction, and more specifically, to improve the operation of the curtain strings simply and conveniently, and to soften the feeling during operation, and at the same time, the magic that has a structure that can change the interior atmosphere It's about shades.

In general, the curtain is installed to be rolled up or unfolded in the horizontal direction, but in contrast, the magic shade is configured to be rolled up and unfolded in the vertical direction, so that the quality of the indoor atmosphere is higher than that of the general curtain that is horizontally rolled up. It is evaluated.

Known magic shades are formed by winding the ropes with a spool provided on a support rod for suspending the shaded body, in order to be able to pull up or unfold the shaded body formed in several stages up and down with a rope. Has a structure in which the sprockets and chains arranged laterally of the chassis are driven in the forward or reverse direction.

Since the magic shade of this structure is reversed when the shade body is lifted up and unfolded, the user often has the inconvenience of causing a mistake in the direction in which the rope is pulled. Since the rope receives the braking force of the automatic brake installed inside the sprocket, there is a disadvantage in that the operation feeling is not good because a considerable force is applied to the pulling operation.

In addition, the known magic shade is expensive and expensive, but there is no structure that can change the indoor atmosphere, so the user easily feels boredom.

The present invention is devised to solve the disadvantages and shortcomings seen in the above-described conventional magic shade, and it is possible to expand or roll up the shade body even when operating in one direction to obtain the simplicity of operation and a smooth operation feeling. At the same time, the aim is to provide a magic shade with a configuration that can change the atmosphere of the room into two patterns of atmosphere.

The present invention for realizing the above object, the polygonal rod is rotatably installed horizontally to the inner center of the chassis attached to the top of the door frame, the upper end of the shade body is suspended in the chassis, the main rope is bound to the bottom end of the shade body Is wound around the spool of the hoisting means installed through the polygon rod, and the polygon rod is rotated by an operation chain disposed on one side of the chassis so that the shade body can be unfolded up or down and rolled up. As the magic shade, the rotation of the polygonal bar is set to be divided into active rotation by the weight of the weight bar attached to the lower end of the shade body and driven rotation by the user pulling the operation chain. After the active rotation is stopped under certain conditions, the user pulls the operating chain and the rod is driven after When the negative rotation is active rotation, the rotation control means for controlling to rotate in the same direction as the polygonal bar, and the next rotation after the polygonal rod is driven, only the polygonal bar to rotate when the driven rotation continues.

The rotation control means accommodates and arranges a constant speed rotating shaft in which a pair of speed reducing members arranged with pressure torsion springs are axially supported on a fixed shaft of a flange in an interior of the speed reducing cover through which the hole is opened, and communicated with the speed reducing cover. Inside the casing is formed a mooring groove, an endless circulation path, and a bypass path with a closed groove, including a stopper having a branching point on its outer circumferential surface and a pick-up protrusion opposite to it, and accommodating a roller cam having a linking groove formed on one side thereof. And a spring seat for receiving and supporting a clutch spring into which the one end is inserted into the linking groove is seated on the casing, and arranged to be rotated separately from the roller cam together with the constant speed rotation shaft. It is supported by the polygonal rod together with the constant speed rotation shaft and always rotates synchronously.

In addition, the magic shade of the present invention is located at the top of the chassis is provided with a main channel which is a rectangular partitioned space inside, and a sub-channel forming a separate partitioned space on both sides of the lower side. The weight bar is arranged in several stages up and down, and the weight bar installed at the bottom of each stage has an outer knot in which one end of the lobe interlocking rope is connected to the front, and the weight bar is attached to the lower end, and both sides of the main body have two strands. It is formed of a shade body bound with a rope, so that the outer knot can be raised or unrolled with respect to the shade body.

In addition, the magic shade of the present invention can be detached and attached arbitrarily by the Velcro fastener between the front and rear surfaces of the chassis and the upper side of the shade body.

The present invention, as shown in Figure 1, the chassis 2 attached to the upper end of the door frame, the outer outer four (4) arranged in the shape of a follicle, made up of several stages arranged up and down, and these outside It has an appearance characteristic of a shade body 6 which is arranged to form one surface directly on the back side of the apnea 4.

The outer core 4 formed in several stages spreads well by providing the weight bar 8 in each lower end, and the shade body 6 also has the weight bar 10 in the lower end side similarly.

The outer core 4 is to be sewn to be substantially draped over the front of the shade body 6, but they can be folded or unfolded separately through different paths.

That is, the outer core 4 is bound to the lower weight bar 10, the binding rope 12 is bound to extend upward through the back, can be raised or unfolded sequentially, the shade body 6 is Two strands of the main rope 14 are bound on both sides of the lowermost weight bar 10, thereby making it possible to lift and unfold it.

In more detail, the knot interlocking rope 12 is formed by knots at points adjacent to the weight bar 8 of each step, and is rolled up and down sequentially, and the knot is shown in FIG. 2. The knot is formed by hanging the stoppers 12a attached to each pair in predetermined positions in the middle of the knot interlocking rope 12 on the S-shaped hook 12b previously sewn on the rear surface of the outer knot. If the structure is made to be easy to install and handle, the lower end portion of the main rope 14 for interlocking the shade body 6 as a whole can be connected in the same structure.

In addition, these astringent interlocking ropes 12 and the main ropes 14 respectively extend to the lower side of the chassis 2 and are guided along a plurality of guiders 16 suspended therein to extend to predetermined positions, but the path Is completely different, the interlocking linkage rope 12 extends through the lifting adjustment mechanism 18 attached to one side of the bottom of the chassis 2, it is installed so that only the outer knot 4 can be arbitrarily raised or unfolded, The other two strands of main rope 14 extend in the middle through the guider 16 at both ends of the chassis 2, and are wound by the lifting means 22 accommodated inside the chassis 2, so that It is installed so that the whole shade body 6 can walk or unfold.

As a result, the magic shade of the present invention has an atmosphere in which the outer tuber 4 is cast from the shade 6, and the outer tuber 4 is rolled up as shown in FIG. It can be changed in two patterns.

Referring to FIG. 1 again, the hoisting means 22 is interlocked and rotated by the operation chain 22 attached to one side of the chassis 2, and the rotation direction thereof is controlled by the rotation control means 24. The velcro fasteners 26a and 26b are interposed between the rear face of the chassis 2 and the upper side of the shade body 6 so that the shade body 6 can be detached and attached arbitrarily.

4 illustrates the components arranged in and out of the chassis 2.

In the figure, the chassis 2 has a rectangular main channel 28 therein, and sub-channels 30 in which the guider 16 and the lifting adjustment mechanism 18 are inserted and arranged at both sides thereof. Is formed. In addition, a polygonal rod 32 is arranged in the longitudinal direction at the center of the main channel 28, which penetrates the centers of the lifting means 22 and the rotation control means 24 by the operation chain 22. It is supposed to receive torque.

The guider 16 has an active plate 34 upwardly, and the active plate 34 is slidably inserted into the sub-channel 30 so that the guider 16 can be inserted into the chassis 2. It can arrange to move to any lower position.

In this configuration, the lifting adjustment mechanism 18 is composed of a housing 40 in which two rollers 36 and 38 are disposed inward, as shown in FIG. 5.

The interlocking interlocking rope 12 enters one side of the housing 40 and extends outwardly again between the rollers 36 and 38. On the other hand, although both the rollers 36 and 38 are arranged to be freely movable in the interior of the housing 40, the housing 40 is any one of the rollers 36 at the outlet from which the interlocking interlocking roller 12 extends. The lower end surface of the side which contacts one is formed in the uneven surface 42. As shown in FIG.

Such a structure allows the user to grasp the apical interlocking rope 12 extending outwardly from the lifting adjuster 18 by hand and operate it laterally, as indicated by the dashed-dotted line in FIG. Once the roller 36 is pulled upward in the direction of arrow 'A' in the drawing, the roller 36 is pushed upward from the position 'B' and placed in a solid line position, whereas the opposite roller 38 is moved downward by its own weight. Both rollers 36 and 38 are in a state capable of freely rotating, so that the interlocking interlocking rope 12 can freely pass between both rollers 36 and 38, so that the user can move the outer ) Can be raised or unrolled arbitrarily.

Further, when the asymmetrical interlocking rope 12 is pulled once along the direction of arrow 'C' in the drawing, the roller 38 moves from the lower side to the position 'D', and the opposite roller 36 falls down by its own weight. It is brought into contact with the uneven surface 42 again. In this state, the roller 36 cannot engage with the uneven surface 42 to be rotated, and as a result, the interlocking interlocking rope 12 is caught between the rollers 36 and 38 and stopped. The outer knot 4 also stops at that position.

In this way, the magic shade of the present invention, as the outer lobe 4 is raised or unrolled by the lobe interlocking rope 12, the atmosphere formed by the outer lobe 4, and this is rolled up to form the rear shade body. It can be selectively used in two patterns of the atmosphere which (6) expresses.

In the present invention, the main rope 14, which is operated when the whole magic shade is raised or unrolled, is wound or unwound by the lifting means 22 shown in FIG.

6 is a perspective view showing an example of the configuration of the hoisting means 22, which includes a spool 48 rotatably supported between both sidewalls 46 of the bracket 44 fitted into the chassis 2. . The spool 48 has a passage 50 for connecting one end of the main rope 14 to one side of the outer circumference thereof, the center of which is a polygon rod 32 disposed across the inside of the chassis 2. It is formed of a corresponding polygonal hole (52), and the bracket (44) is covered with a clip (56) on one side end portion 54 of the chassis (2) by the fastening bolt 58 and the fastening nut (60). It is structured to be attached and fixed with).

The rotation control means 24 disposed at an arbitrary position inside the chassis 2 is configured as shown in FIG. 7 to control the rotation direction of the polygon rod 32. In FIG. 7, a spring seat in which the constant speed rotation shaft 64, the roller cam 66, and the clutch spring 68 are fitted to the outer circumference of the casing 62 substantially constituting the rotation control means 24 ( 70 is arranged to be accommodated coaxially.

A flange 72 is integrally formed at one end of the constant speed rotation shaft 64, which is rotatably supported by an axial hole 74 opened in the rear side of the casing 62, and is fixed to the flange 72 at a constant speed. A pair of fixed shafts 76 extending in parallel with the rotation shaft 64 are provided. The small holes 80 of the deceleration piece 78 which are arranged on the outer circumference of the constant speed rotation shaft 64 are respectively fitted to the pair of fixed shafts 76, and the deceleration piece 78 is centered on the fixed shaft 76. And a torsion spring 82 is provided between the pair of deceleration pieces 78, and the elastic force of the torsion springs 82 is always fixed to the fixed shaft 79. Acts as a bias.

In addition, the end of the constant speed rotation shaft 64 is axially supported by the rear side through-hole 86 of the deceleration cover 84 that is integrally attached to the rear side of the casing 62 and surrounds the periphery of the deceleration piece 78. .

The roller cam 66 has a circulation path 88 that extends indefinitely on one side of the outer periphery, and also has a mooring groove 92 defined by the stopper 90, and a branching point formed below the stopper 90. A bypass passage 96 branching from the circulation passage 88 at 94. On the opposite side of the stopper 90, a pick-up projection 98 is formed to form an acute angle to limit the range of the mooring groove 92, and at the same time as the end of the bypass passage 96, the mooring groove 92 It is intended to define a blind groove 100 that is turned 180 degrees to lead to.

On the other hand, the side of the roller cam 66, the coupling groove 102 is fitted with one end of the clutch spring 68 is formed.

The clutch spring 68 is fitted into the seat shaft 104 formed in the spring seat 70, and the end side small diameter shaft portion 106 of the seat shaft 104 is a circular hole drilled in the center of the roller cam 66. It is rotatably inserted and supported by 108.

In addition to the small diameter shaft portion 106, the circular hole 108 of the roller cam 66 also supports the shaft portion 110 extending in the symmetrical direction to the constant speed rotation shaft 64 of the flange 72.

The centers of the constant speed rotating shaft 64 and the spring seat 70 are each formed of polygonal holes 112 and 114 through which the polygonal rod 32 penetrates to rotate in conjunction with the polygonal rod 32 penetrating therethrough. do.

When the constant speed rotation shaft 64, the roller cam 66, the spring seat 70, and the like are housed and disposed in the casing 62, the cover 116 is finally attached, and the cover 116 is the spring seat 70. It will also serve as a bearing for.

In addition, the upper side of the casing 62 is formed to extend in the form of an active path 118 protruding to the outside, the active path 118 is driven to ride the outer peripheral surface circulation path 88 of the roller cam 66 The ball 120 is stored.

When the roller cam 66 is rotated, the ball 120 slides in the circulation path 88, the bypass path 96, and the mooring groove 92 on the activity path 118, and also the ball 120. ) Interferes with the branch point 94 or the pick-up projection 98 in accordance with the rotational direction of the roller cam 66, and slides to change the passage.

The interaction between the roller cam 66 and the ball 120 described above is operated in three modes: the operation of lifting up the magic shade of the present invention, the operation of unfolding, and the stop operation.

Referring to the operation mode in more detail with reference to FIG. 8, the initial position of the ball 120 indicated by the dashed-dotted line in the figure is the mooring groove 92, in which the multi-rod by the operation chain 22 ( 32, the entire shade body 6 is lifted up when the rotational direction of the drawing is driven along the direction of the arrow E in the drawing, while the shade body (when the polygon rod 32 is the active rotation along the direction of the arrow F in the drawing). 6) is unfolded.

In addition, the spiral direction of the clutch spring 68 should be set in advance so as to coincide with the arrow F direction.

When the polygon rod 32 rotates, if the clutch spring 68 is rotated one or more times in the direction of the arrow E, the diameter thereof is expanded and slips on the outer circumference of the seat shaft 104, and the roller cam 66 The power is cut off between the seat shafts 104 and the winding direction in the rotation of the arrow F. The power is transferred between the roller cam 66 and the seat shafts 104.

The helical winding of the clutch spring 68 should be set such that the state where the ball 120 is located in the mooring groove 92 can be a power transmission state between the roller cam 66 and the seat shaft 104. do.

The polygon bar 32 is subject to the external force to be rotated in the direction of the arrow F at all times until the shade 6 receives the weight of the weight bar 10, until it is fully unfolded. The external force applied to the polygon bar 32 is transmitted to the roller cam 66 via the spring seat 70 and the clutch spring 68 at the polygon bar 32.

However, since the rotation of the arrow F direction of the roller cam 66 becomes a direction in which the ball 120 moving only by a constant trajectory by the activity path 118 is caught by the stopper 90, the roller cam 66 stops. The state is maintained, and thus, the polygonal rod 32 also remains stationary.

In the stationary state, when the user pulls the operation chain 22 only slightly in the direction of the arrow E, the rotation of the polygon rod 32 and the seat shaft 104 rotates in the same direction, and at this time, the clutch spring 68 ) Is rotated in the unwinding direction, but the rotation angle is less than once, and the roller cam 66 is in a no-load state with respect to the rotation in the direction of the arrow E. Therefore, the seat shaft 104 and the roller cam ( 66 is rotated in the direction of the arrow E as a result, the ball 120 is pushed onto the circulation path 88 in contact with the pick-up projection 98 of the roller cam 66 in the mooring groove (92).

When the ball 120 is placed at the point G on the circulation path 88 by the pick-up protrusion 98, the roller cam 66 can rotate freely without interfering with the branch point 94 only when it follows the arrow F direction. At this time, if the user releases the operation chain 22 without pulling, the polygon bar 32 is operated by the external force by the weight bar 10, and rotates in the direction of arrow F while the spool 48 of the hoisting means 22 is rotated. ), The main rope 14 wound up is released, and as a result, the shade 6 is unfolded.

Moreover, since the rotation of the arrow F direction of the polygonal rod 32 is the winding direction of the clutch spring 68, the seat shaft 104 and the roller cam 66 rotate synchronously in a power transmission state.

Contrary to the above operation, in a stationary state, the user pulls the operation chain 22 lightly once so that the ball 120 is placed at the position G on the circulation path 88, and then continues to pull the polygon rod 32 further. Is rotated in the direction of arrow E and moved to position H, where it interferes with the branch point 94 of the stopper 90, changes its course to the bypass path 96, and is caught in the blocked groove 100.

Since the blocked groove 100 serves to prevent the roller cam 66 from rotating in the direction of the arrow E, when the ball 120 is located in the blocked groove 100, the rotation of the roller cam 66 is Is stopped.

On the other hand, the rotation of the polygon rod 32 in the direction of the arrow E by the user is in the release direction of the clutch spring 68, and the rotation at this time is performed one or more times, thereby slipping on the outer circumferential surface of the seat shaft 104, Accordingly, even if the rotation of the roller cam 66 is stopped by the blocked groove 100, the rotation of the polygon rod 32 in the direction of the arrow E is continued to maintain the main rope 14 through the spool 48 of the lifting means 22. Roll up the shade body (6).

In this way, when the main shade 14 is lightly pulled and released while the magic shade is being rolled up, the roller cam 66 is slightly rotated in the direction of the arrow E so that the ball 120 is mooring groove 92 in the blocked groove 100. The position of the weight bar 10 acting on the roller cam 66 and the elastic force of the clutch spring 68 are reversed in the direction of the arrow F while being caught by the stopper 90 and returned to the stopped state. Thus, the shade 6 is completely rolled up or stopped as it is.

This action, even when the ball 120 unfolds the shade body 6 while riding the circulation path 88 in the direction of the arrow F, when the user gently pulls the main rope 14 again, the ball 120 is a circulation path In step 88, the path is changed to the bypass path 96 to move to the blocked groove 100, and then to the mooring groove 92.

On the other hand, when the shade body 6 is unfolded by the polygon bar 32 which is rotated according to the operation as described above, it unfolds in a no-load state with respect to the weight of the weight bar 10, so it unfolds very quickly and is embarrassed to the user. There is a risk of giving.

However, according to the present invention, the pair of deceleration pieces 78 are rotated outwardly while decelerating against the torsion spring 82 by the action of centrifugal force by the rotation in the constant speed rotation shaft 64 synchronously rotating with the polygon rod 32. By rubbing against the inner circumferential surface of the cover 84, the rotation speed of the polygonal rod 32 is reduced, and the shade body 6 is gradually unfolded.

Since the frictional force due to the opening of the deceleration piece 78 is shown in proportion to the centrifugal force, when the magic shade is lifted up, the direction of rotation is reversed and its rotational speed is not fast, and is smaller than the elastic force of the torsion spring 82. Does not appear Therefore, in the process of lifting up the shade 6, the load by the frictional force of the deceleration piece 78 is not acted on, so that the user can lightly lift the shade 6.

As described above, the magic shade of the present invention has the convenience of allowing the user to lightly pull and release the operation chain, or to simply pull and pull the operation chain further, to unfold or lift the entire shade body.

This feature of the present invention allows the user to not confuse the operation direction of the operation chain.

In addition, the magic shade of the present invention, by the outer gradation to the front of the shade body step by step, these outer vesicles are rolled up or unfolded by a separate entanglement interlocking rope, so the atmosphere created by the outer vesicles, There is also an advantage in that the atmosphere created by the shade body on the back side can be used selectively.

In addition, the Velcro fasteners are attached to the front and back of the chassis, so that the shade body can be easily attached and detached, and thus the product has excellent merchandise such as easy installation and disassembly of the shade for washing.
