Description

[0001] Electric blind apparatus [0002]

The present invention relates to an electric blind device configured to automatically rotate a roller by using the electric force of the motor, and more particularly, to be configured to extend in the longitudinal direction and configured to rotate two or more rollers with one motor. It relates to a motorized blind device.

In general, curtains or blinds are installed in the windows of a building for privacy protection, selective lighting, heating, and the like, and the blind devices are conveniently used because they can control the amount of light.

In general, the blind device is divided into a sheet-type blind device that covers the window with a single sheet, and a slate-type blind device that covers the window with a plurality of slates having a predetermined width and length, and the rotation of the roller lying down so that the rotation axis is horizontal. The seat and the slate are raised and lowered in accordance with the direction so as to cover or open the window. The sheet-type blind device is operated so that one end of the sheet is wound on the roller according to the rotational direction of the roller by being coupled to the roller, and the slat-type blind device is coupled to the roller and one end of the wire connecting the plurality of slats is rotated.

Electric blind apparatus according to the present invention includes a roller which is rotated by the driving force of the motor, the sheet is wound on the roller or the wire connecting the plurality of slates is wound, thereby opening or covering the window according to the rotation direction of the roller To operate the device. In this case, the electric blind apparatus according to the present invention is configured to include a first blind 100 and a second blind 200 which can be coupled to the roller in which the sheet or the wire is wound in the longitudinal direction, and the center portion even if the overall length is increased. In addition to preventing the sag down, the internal configuration is simplified and the roller is rotated by rotating the roller included in the first blind 100 and the roller included in the second blind 200 together with one motor. It is characterized by the fact that it is configured to reduce the energy consumption for use.

In order to achieve the above-mentioned effect, the first blind 100 is arranged between the pair of first side plates 104 and the pair of first side plates 104 arranged side by side to be spaced apart from each other. A first cassette head 102 covering the upper and side surfaces thereof, a driving roller 110 coupled to the first side plate 104 in a rotatable structure, and a motor inserted into the driving roller 110. It is configured to include a motor (not shown) installed in the housing 120 to rotate the drive roller 110. In addition, the second blind 200 includes a pair of second side plates 204 arranged side by side so as to be spaced apart from each other, and a second cassette covering upper and side surfaces between the pair of second side plates 204. Head 202, driven roller 210 coupled to the both sides in the longitudinal direction rotatable to the first side plate 104, and both sides in the longitudinal direction are inserted into the drive roller 110 and driven roller 210 It is configured to include an end shaft 240 to be coupled to rotate the driven roller 210 and the drive roller 110 integrally. In addition, the first end cap 106 and the second end of the first side plate 104 and the second side plate 204 to prevent dust or foreign matter from flowing into the driving roller 110 and the driven roller 210. The cap 206 is mounted.

In the present exemplary embodiment, the first cassette head 102 and the second cassette head 202 are fixed to the wall by a separate fastening bracket 300, but the fastening bracket 300 is shown as a representative. It may be configured to fix the first side plate 104 and the second side plate 204 to the wall, the first cassette head 102 and the second cassette head 202 is directly fixed to the wall or the first side The plate 104 and the second side plate 204 may be configured to be directly fixed to the wall. That is, the method of fixing the first blind 100 and the second blind 200 to a wall may be variously modified, and thus a detailed description thereof will be omitted.

As mentioned above, when the driving roller 110 and the driven roller 210 are connected to be integrally rotated by the end shaft 240, the driving roller 110 and the motor mounted on the motor housing 120 are driven. Since the driven roller 210 is integrally rotated, it is possible to obtain an effect that a separate motor for rotating the driven roller 210 is not required. That is, as the separate motor for rotating the driven roller 210 and various kinds of parts thereof can be omitted, the internal structure of the second blind 200 is simplified, thereby reducing the manufacturing cost of the product. Since the two rollers can be rotated, the maintenance cost is reduced.

In addition, both ends of the driving roller 110 are coupled to the pair of first side plates 104, and both ends of the driven roller 210 are coupled to the pair of second side plates 204. Even if the overall width of the electric blind device is increased, that is, the total length of the roller (total length connecting the driving roller 110 and the driven roller 210) can be increased so that it can be used in a wide window, The effect is that sag does not occur. In particular, when the total length of the roller is required to be very long, if the roller is made of one long, the center portion can be easily sag down by its own weight, two or more second blind in one first blind 100 as in the present invention The additional connection of the 200 has the advantage that the phenomenon of sagging in the middle of the roller due to its own weight does not occur.

On the other hand, when the rotating shaft of the motor seated in the motor housing 120 is rotated, the motor body, that is, the motor housing 120 can be rotated in the opposite direction in response to the rotation of the rotation shaft, the motor housing 120 as described above When the rotation of the drive roller 110 can not be normally rotated when the rotation, only the rotation shaft of the motor when the motor is rotated and the motor housing 120 should be maintained in a fixed state. Therefore, the electric blind apparatus according to the present invention includes a drive shaft block 122 into which the rotation shaft of the motor seated in the motor housing 120 is inserted, a rotation block 124 surrounding the drive shaft block 122, and one side (the present). In the embodiment, the right side is fixedly coupled to the motor housing 120 and the other side (left side in this embodiment) is connected to the connecting bracket 132 with the drive roller 110 outside, and one side is the first side plate 104. The motor fixing shaft 130 is further provided to fix the connection bracket 132 to the first side plate 104 by penetrating through the connection bracket 132. At this time, so that the connection bracket 132 is not rotated, the connection bracket 132 is formed in a polygonal inner diameter, it is preferable that the protrusion of the motor fixing shaft 130 is drawn into the connection bracket 132 is also formed in a polygonal shape. Do. Accordingly, when the motor seated in the motor housing 120 is driven, the drive shaft block 122 into which the rotation shaft of the motor is inserted, and the rotation block 124 and the driving roller 110 which are integrally coupled thereto are rotated integrally. 1 The motor fixing shaft 130 fixedly coupled to the side plate 104, the connection bracket 132 and the motor housing 120 connected thereto are maintained in a fixed state.

The end shaft 240 may be configured to directly connect the driving roller 110 and the driven roller 210, in this case, the internal structure of the driving roller 110 and the driven roller 210 becomes complicated, Accordingly, not only a lot of difficulty may be generated in the production of the driving roller 110 and the driven roller 210, but also damage to the coupling portion of the end shaft 240 in the power transmission process of the driving roller 110 and the driven roller 210. If it occurs, there is a problem that the driving roller 110 and the driven roller 210 must be replaced. In addition, when the end shaft 240 is fixedly coupled to the driven roller 210, when the second blind 200 is connected to the right side of the first blind 100, the second blind 200 is moved from right to left, that is, leftward. The end of the end shaft 240 should be inserted into the driving side plug 140 by moving the second blind 200 in the horizontal direction. When the right side space of the first blind 100 is not sufficiently secured, the first blind 100 Many difficulties may occur in the operation of additionally coupling the second blind 200 to the.

Therefore, the electric blind device according to the present invention is formed to have a polygonal inner diameter, that is, a polygonal groove 144 so as to solve the above problems, the drive side plug 140 is inserted into one side of the drive roller 110 in the longitudinal direction. And a driven side plug 220 formed to have a polygonal groove 224 and inserted into a side of the driven roller 210 corresponding to the driving side plug 140, and the end shaft 240 has a length. One side in the direction (left in this embodiment) is inserted and coupled to the driven side plug 220 in a slidable structure to be pulled out of the driving side plug 140, so that the driving side when one side in the longitudinal direction is drawn out It may be inserted in a fitting manner to the inner diameter of the plug 140. As such, when the end shaft 240 is coupled in a sliding structure to allow the inlet and out of the driven side plug 220 to be inside, the end shaft 240 when the driving roller 110 and the driven roller 210 are aligned in line. Since it can be completely drawn into the driven plug 220, it is possible to match the end of the drive roller 110 and the driven roller 210 while moving the second blind 200 in the radial direction of the driven roller (210). Will be.

At this time, after the driving roller 110 and the driven roller 210 are arranged in a line, one side of the end shaft 240 in the longitudinal direction is inserted into the driving roller 110, and the driving roller 110 and the driven roller 210 are formed. ) Should be connected to rotate integrally. Therefore, when the end of the driving roller 110 and the end of the driven roller 210 is exactly matched, the end shaft 240 and the driven plug 220 so that one side in the longitudinal direction of the end shaft 240 can be automatically drawn out. It is preferable that the recovery means 250 for applying an elastic force to the end shaft 240 in the direction in which one side of the end shaft 240 in the longitudinal direction is drawn out of the drive side plug 140 between the (). In this embodiment, only the case in which the restoring means 250 is applied as a coil spring, the restoring means 250 may be replaced by a pin spring or various elastic means in addition to the coil spring shown in the present embodiment. have.

Meanwhile, in the electric blind apparatus according to the present invention, as shown in FIGS. 1 and 7, another second blind 200 is additionally added in a state where the first blind 100 and the second blind 200 are coupled. To be connected, the end shaft included in another second blind 200 on the other side in the longitudinal direction of the driven roller 210, ie, the side of the driven roller 210 to which the driven plug 220 is coupled. Preferably, an extension plug 240 is additionally provided that can be inserted. As such, when the end shaft 240 is provided at one side of the driven roller 210 in the longitudinal direction and the extension plug 230 is provided at the other side in the longitudinal direction, the second blind 200 can be additionally connected to any number thereof, and thus the width size thereof. Has the advantage of being applicable to different kinds of windows. At this time, the extension plug 230 is preferably formed in the same way as the drive-side plug 140 so as to realize the manufacturing cost reduction of the product through the common parts.

Meanwhile, when the driving roller 110 and the driven roller 210 are rotated in the process of combining the first blind 100 and the second blind 200, the ends of the driving roller 110 and the driven roller 210 coincide with each other. Not only the work becomes difficult, but also problems such as unwinding of sheets or wires wound around the driving roller 110 and the driven roller 210 may occur. At this time, the driving roller 110 is not rotated arbitrarily because it is connected to the rotation shaft of the motor, the driven roller 210 may be rotated arbitrarily because there is no separate configuration for limiting the rotation. Therefore, the electric blind device according to the present invention may be further provided with a fixing pin 400 inserted over the driven roller 210 and the second side plate 204 to limit the rotation of the driven roller 210 ( For reference, in FIG. 7 to the left side of the first side plate 104 and the driven roller 210 coupled to the right side of the driving roller 110 in order to clearly show the connection structure of the driving roller 110 and the driven roller 210. Combined second sideplate 204 is omitted). When the fixing pin 400 is inserted, the driven roller 210 is connected to the second side plate 204 by the fixing pin 400, and the second side plate 204 is fixed to the second cassette head 202. Since the driven roller 210 is also coupled to it can be maintained in a state that does not rotate or move. The timing for inserting and removing the fixing pin 400 will be described in detail with reference to FIGS. 10 to 13. Of course, if there is a possibility that the drive roller 110 is arbitrarily rotated despite being connected to the rotation shaft of the motor, the fixing pin 400 is inserted across the first side plate 104 and the drive roller 110 It may be utilized to limit the rotation of the drive roller 110.

8 and 9 are an exploded perspective view and a side view showing a coupling structure of the end shaft 240 included in the present invention.

In order for the driving side plug 140 to be integrally rotated with the driving roller 110 and the driven side plug 220 is integrally rotated with the driven roller 210, the driving side plug 140 and the driven side plug 220 are It is to be fixedly coupled to the drive roller 110 and the driven roller 210 or inserted into the fitting method, the drive side plug 140 and the driven side plug 220 to the drive roller 110 and the driven roller 210 When the fixed coupling, respectively, the drive side plug 140 and the driven side plug 220 can not be repaired and replaced, the drive side plug 140 and the driven side plug 220 is driven roller 110 and driven roller 210 When inserted in the interference fit method in the drive side plug 140 and the driven side plug 220 is a problem that it becomes very difficult to pull the operation into the drive roller 110 and driven roller 210 inside. Therefore, the electric blind device according to the present invention can easily drive the drive side plug 140 and the driven side plug 220 into the drive roller 110 and the driven roller 210, while the drive side plug 140 and A locking jaw 112 is formed on the inner circumferential surface of the drive roller 110 and the inner circumferential surface of the driven roller 210 so that the driven side plug 220 can be integrally rotated with the drive roller 110 and the driven roller 210. Preferably, the driving side plug 140 and the driven side plug 220 are formed with protrusions and protrusions 142 and 222 which protrude so as to interfere with the locking step 112 when rotating. In addition, the rotation block 124 for transmitting the rotational force of the motor to the drive roller 110 is also preferably formed with a protruding end 126 protruding so as to interfere with the locking step 112 during rotation. At this time, the driven roller 210 is also preferably a locking jaw 112 is formed like the drive roller 110, the driven roller 210 has the same structure as the drive roller 110, the driven roller 210 ) Will be omitted.

On the other hand, even if the end shaft 240 is pulled out to the drive-side plug 140 side by the elastic force of the restoring means 250 as much as possible, two or more elastic to the driven side plug 220, so as not to be completely separated from the driven side plug 220 A shaft fastening hole 226 through which an end of the piece 242 passes is formed, and the end shaft 240 extends in the longitudinal direction of the driven roller 210 on the side (right side in FIG. 8) drawn into the driven side plug 220. Is provided with two or more elastic pieces 242 extending to be inserted into the shaft fastening hole 226, the end of the elastic piece 242 penetrating the shaft fastening hole 226 of the shaft fastening hole 226 Insertion protrusions 244 protruding in the radial direction may be formed. As such, when the elastic piece 242 having the insertion protrusion 244 formed at the end is provided on the end shaft 240, the end shaft 240 is inserted as shown in FIG. 7 when the end shaft 240 is coupled to the driven plug 220. After the protrusion 244 penetrates the shaft fastening hole 226 and opens wider than the diameter of the shaft fastening hole 226, the end shaft 240 does not hold the two or more elastic pieces 242. It will not be removed from the driven plug 220.

In addition, when the outer diameter of the end shaft 240 and the inner diameter of the driving side plug 140 are formed to be the same, the rotation angle of the end shaft 240 and the rotation angle of the driving side plug 140 must be exactly the same to allow insertion. Therefore, there may be a difficulty in the process of inserting the end shaft 240 into the drive side plug 140. That is, as shown in this embodiment, when the outer diameter of the end shaft 240 is manufactured to have a hexagonal cross section, when the inner diameter of the driving side plug 140 is manufactured to a hexagonal shape, each vertex and the driving side of the end shaft 240 are formed. Since the end shaft 240 may be drawn into the driving side plug 140 only when the inner diameter vertices of the plug 140 exactly match, there may be difficulty in connecting the first blind 100 and the second blind 200. .

In order to solve this problem, the electric blind device according to the present invention does not form a regular polyhedron, as shown in FIG. 9, instead of the inner diameter of the driving side plug 140, that is, the cross-sectional shape of the polygonal groove 144. The inner diameter of the groove 144 may be manufactured in a shape having irregularities such as teeth, that is, a plurality of threads arranged in a circular shape. As such, when the inner diameter of the driving side plug 140 is manufactured in a shape in which a plurality of threads are arranged in a circular shape, even if the end shaft 240 is roughly pushed in, the driving side plug 140 may be inserted into the driving side plug 140. In the state in which the 240 is inserted into the driving side plug 140, the driving side plug 140 and the end shaft 240 are rotated integrally, so that a problem does not occur even in power transmission.

10 to 13 are cross-sectional views sequentially showing the mounting process of the electric blind device according to the present invention.

When installing the electric blind apparatus according to the present invention on the wall, as shown in Fig. 10, the first blind 100 is first mounted on the wall. At this time, the first blind 100 may be configured to be fixed to the wall by a separate fastening bracket 300, as shown in this embodiment, the first side plate 104 or the first cassette head 102 May be coupled directly to the wall.

As such, when the first blind 100 is installed on the wall, the second blind in the radial direction of the driven roller 210 in the state in which the end shaft 240 is pushed into the driven plug 220 inside as shown in FIG. 11. By moving the 200, the position of the second blind 200 is adjusted so that the end of the driving roller 110 and the end of the driven roller 210 coincide. Of course, in order to prevent the driven roller 210 from rotating in this process, the fixing pin 400 should be inserted into the second blind 200.

When the end of the driving roller 110 and the end of the driven roller 210 coincide with each other during the adjustment of the position of the second blind 200, the end shaft 240 is restored as shown in FIG. 12. Protrudes by the elastic force of the driving side plug 140 is drawn into the inside. As such, when the protruding end of the end shaft 240 is completely inserted into the driving side plug 140, the second blind 200 is fixedly coupled to the wall. When the fixing of the walls of the first blind 100 and the second blind 200 is completed, as shown in FIG. 13, the fixing pin 400 is removed, and the driving roller 110 and the driven roller 210 when the motor is started. To be rotated integrally. Of course, in the present exemplary embodiment, only one second blind 200 is connected to the first blind 100 fixed to the wall, but the right side of the second blind 200 is shown in FIG. 12. By further connecting another second blind 200, the overall length of the roller can be freely increased.

As described above, the electric blind apparatus according to the present invention has the advantage that the roller can be freely increased or decreased in accordance with the user's selection, while preventing the roller from sagging downward due to its own weight. In addition, when the end shaft 240 is configured to be elastically retractable into the driven side plug 220, the second blind 200 is driven while moving in the radial direction of the driven roller 210, that is, in the front and rear and up and down directions. Since the end of the roller 110 and the end of the driven roller 210 can be accurately matched, there is an advantage that the first blind 100 and the second blind 200 can be easily combined even in a narrow space.

14 and 15 are a perspective view and a cross-sectional perspective view of a second embodiment of the end shaft included in the motorized blind apparatus according to the present invention, and FIGS. 16 and 17 are a second embodiment of the end shaft included in the motorized blind apparatus according to the present invention. It is sectional drawing which shows an example operation.

As shown in FIG. 13, since the end shaft 240 is not exposed to the outside in the state where the first blind 100 and the second blind 200 are coupled, only the end shaft 240 may be moved to the right. As a result, the operation of separating the driving plug 140 and the driven plug 220 may be very difficult. Of course, the entire second blind 200 may be moved to the right to draw one side in the longitudinal direction of the end shaft 240 from the driving side plug 140, but the embodiment shown in FIG. 13 shows the second blind 200. Since there is not enough space to move the right side), there is a problem that the first blind 100 and the second blind 200 cannot be separated unless the first blind 100 is removed from the wall. Is generated.

The electric blind apparatus according to the present invention may have a structure in which only the end shaft 240 is movable in a state in which the first blind 100 and the second blind 200 are coupled to each other to solve such a problem. . That is, the end shaft 240 has a length in the sliding direction and is formed with an inclined groove 246 having a gradient to deepen toward one side in the longitudinal direction, the driven plug 220 is corresponding to the inclined groove Through holes may be formed at the points.

When the inclined groove 246 is formed in the end shaft 240 as described above, when the user wants to separate the first blind 100 and the second blind 200, the driven plug as shown in FIG. 16 is first shown. A pin-shaped stripping tool 10 is inserted into the through-hole formed in 220. When the removal tool 10 is pushed further in the state shown in FIG. 16, a sliding motion occurs between the end of the removal tool 10 and the bottom surface of the inclined groove 246. The removal tool 10 does not move in the left and right directions. Therefore, as shown in FIG. 17, the end shaft 240 is moved to the right to be pulled out of the driving side plug 140 so that the first blind 100 and the second blind 200 can be easily separated. do.
