Description

The present invention relates to a lifting and moving device for a window, and more particularly, to a lifting and moving device for a window, which includes a slider for raising a window sash and a working plate for driving the slider, and operates so that the working plate is vertically moved by means of an electric motor, and to a lifting control device for a lifting and moving device.

In general, a window lifting and moving device is a device for raising and subsequently moving a window sash when opening or closing a window. Such a lifting and moving device is widely used for relatively large windows, such as interior doors in a living room or balcony windows. The lifting and moving device provides silent and smooth movement of the window when opening or closing, and also provides effects of air tightness, water resistance and sound insulation.

The lifting and moving device mentioned above will be described with reference to FIG. A typical lifting and moving device includes a slider 3 attached to the bottom of the window sash (not shown), and a working plate P attached to the surface of the window sash, which is in contact with the window frame BF. The working plate P is lifted by the handle 5, and thus the slider 3 lifts the window sash with the help of the raised working plate P. The configuration and driving of this device are described in Korean Patent No. 721455, therefore, its details are not considered in this document.

Meanwhile, the operation of lifting the working plate P will be described with reference to FIG. In the prior art, the handle 5 is configured to rotate the drive gear 61, and therefore, the driven gear 65 rotates in such a way that the gear rack gear 67 meshed with the driven gear 65 rises, raising the working plate P. Thus, the frame the sash is lifted as described above, and the user can easily move the sash of the window.

However, in the case of a conventional device for lifting and moving, the user must move the handle 5, as described above, to facilitate lifting and moving the window, which is inconvenient. In particular, a disabled person or an elderly or infirm person who is not able to move the handle 5 is not able to open or close the window.

The present invention has been made to solve the above problems. An object of the present invention is to provide a lifting and moving device that is capable of lifting and moving a sash frame by raising a working plate using electric energy, thereby improving usability and allowing even a disabled or elderly or weak person to open or close a window.

In addition, another objective of the present invention is to provide a control device that contains electrodes mounted at each extreme point of vertical movement of the slider for detecting contact with the slider, and provides precise control of the movement of the slider using a signal transmitted from the electrodes, thereby preventing excessive load on the electric motor and providing reliable upward movement of the sash window.

The mentioned tasks can be achieved by creating a lifting and moving device for a power window, which includes a ball screw rotated by an electric motor, a slider engaged with a ball screw to provide vertical movement, a protrusion protruding from the slider and gripped into the slot formed in the working plate for lifting the working plate by moving the slider, and support plates mounted respectively at both ends of the ball screw to provide his support.

The aforementioned tasks can also be achieved by creating an electric window lift control device including positioning terminals, each of which is electrically connected to a pair of electrodes to determine the position, installed at each of the upper and lower limit points of movement of the slider and electrically connected to each other with a friend through contact with a slider, and electrodes of a control device for determining a position for transmitting a signal to the control device by tact with the findings.

The present invention relates to a window lifting and moving apparatus including a slider for raising a window sash and a working plate for driving a slider in which the working plate is vertically moved by an electric motor.

Below the present invention will be described in detail by means of embodiments and the accompanying drawings.

1st embodiment

In this embodiment, the motor assembly 300 includes a slider 320 fixed to the work plate P for vertically moving the work plate P, a ball screw 310 engaged with a slider 320 to move the slider 320, and an electric motor M for rotating the ball screw 310 as shown in FIG.

That is, to drive the slider 3, as described above, the working plate P must be moved vertically. This embodiment is designed so that the slider 320 is fixed with the working plate P and then vertically moves.

In this case, the electric motor M rotates the ball screw 310. The use of the ball screw 310 is due to the fact that it has less friction on its thread, and is also able to provide high accuracy, since the dead stroke can approach zero.

Meanwhile, the slider 320 is fixed to the ball screw 310 by means of a threaded engagement. That is, the rotation of the ball screw 310 causes a vertical movement of the slider 320.

In this case, the slider 320 includes a housing 321 containing a screw thread, made in it with the possibility of engagement by means of a thread with a ball screw 310, and a protrusion 322, protruding from one side of the housing 321 and fixed with the slit P1 of the working plate P, as described above .

In addition, the support plates 330 and 340 are respectively mounted on both sides of the ball screw 310 to support the ball screw 310.

In this configuration, when the motor M rotates, the ball screw 310 rotates, and then the slider 320 engaged by the thread with the ball screw 310 moves vertically. As a result, the protrusion 322, protruding from the slider 320 and fixed with the slit P1 of the working plate P, raises the working plate P. Thus, if the working plate P rises, the slider 3 raises the window sash, as described above.

Meanwhile, in the present invention, the ball screw 310 is rotated by an electric motor M, and accordingly, the working plate P is lifted as described above. In this case, it is necessary to control the upward movement of the working plate R.

For this purpose, as shown in FIG. 4, a pair of electrodes 330a or 340a is provided for determining the position on each of the inner surfaces of the support plates 330 and 340, i.e. on the surface with which the slider 320 is in contact.

However, since the support plates 330 and 340 have the same shape, only one of the support plates is illustrated in the drawing.

The positioning electrodes 330a or 340a are mounted at a distance from each other and are electrically connected by contact with the slider 320. Due to this configuration, the positioning electrodes 330a or 340a determine the position of the slider 320, and in this case, the movement of the working plate P.

More specifically, the slider 320 is vertically moved with a ball screw 310, as described above. For example, if the slider 320 moves up to the upper limit point, i.e. to the upper support plate 330, the slider 320 is brought into contact with the positioning electrodes 330a mounted on the upper support plate 330. Moreover, the positioning electrodes 330a that are spaced apart from each other and thus are not electrically connected to each other with the other, are brought into contact by means of a slider and thereby electrically connected to each other. If a signal generated appropriately is recorded, then it can be determined that the slider 320 reaches the upper limit point and, thus, stop the operation of the motor M.

Meanwhile, the support plate 330 or 340 contains a mounting hole 331a or 341a, which is made in the housing 331 or 341 of the support plate with the possibility of engagement by thread with a ball screw 310. Moreover, between the electrodes 330a or 340a for determining the position and the housing 331 or 341, preferably, a damping device D is installed to mitigate the shock resulting from contact with the slider 320.

Meanwhile, a device for registering a signal and stopping the operation of the motor M will be described below.

As described above, in the present invention, the ball screw 310 is rotated by a rotational force from the motor M, and accordingly, the slider 320 moves upward, raising the working plate P, as a result of which the slider 3 lifts the window sash. Moreover, if you want to lift the sash by raising the working plate P and then move the sash, then the slider 320 must hold the lifted working plate P, which can cause excessive load on the motor M. Therefore, this problem must be solved.

This configuration to solve the above problems will be described with reference to figure 5. In this case, FIG. 5 shows that the lifting device of the present invention is used in conjunction with a conventional lifting device using a handle, as shown in FIGS. 1 and 2. Although not shown in FIG. 5, the motor assembly 300 assumes the load of the vertical movement of the working plate P, and when using the configuration depicted in figure 5, prevents excessive load on the aforementioned motor M.

That is, another slot is made in the working plate P, i.e. the slit P2 for gripping the latch, and the latch S1 is designed so that it is captured in the slit P2 for gripping the latch. The latch S1 is rotatably fixed in the window sash frame on which the working plate P. is fixed. At the same time, an elastic element E, such as a spring, is mounted on the latch S1, so that an elastic force is used to rotate the latch S1 towards the working plate P.

In accordance with this configuration, when the slider 320 moves up the work plate P, as described above, the latch S1 is captured in the slit P2 to capture the latch. This is done in such a way that the latch S1 rotates under the action of the elastic force of the elastic element E and then enters the slot P2 to capture the latch.

Moreover, when the slider 320 is lowered, the working plate P is not lowered, since the latch S1 is caught in it, and as a result, the sash can be held in a raised position. That is, this means that the window sash can be held in a raised position, even if the load is not constantly applied to the electric motor. Thus, this configuration is able to increase the service life of the lifting and moving device of the present invention.

Meanwhile, when the latch S1 supports the working plate P, as described above, the latch S1 can rotate in the opposite direction due to the weight of the working plate P and thus come out of the working plate P. An element S2 is provided for securing the latch S1 to hold the latch.

The locking element S2 is rotatably mounted under the locking element S1 and receives elastic force from the elastic element E to rotate towards the working plate P. Moreover, the upper part of the locking element S2 is adapted to engage with the lower side of the locking element S1.

According to such a configuration, when the latch S1 supports the working plate P, the S2 element for holding the latch under the latch S1 secures the latch S1, preventing it from turning, as a result of which the latch S1 does not come out of the working plate P, holding the window sash in the raised position.

Meanwhile, the raised position of the window sash is supported by the latch S1 and the S2 element for holding the latch, as described above. Moreover, when it is necessary to lower the window sash, a configuration is required for lowering the working plate P. For this purpose, on the element S2 to hold the latch, you can set the control lock switch S3. Moreover, the control blocking switch S3 is configured to protrude on one side of the element S2 to hold the latch and then pass through the slot P2 to capture the latch of the working plate P.

According to this configuration, if the control lock switch S3 is pressed into a position in which the latch holding member S2 and the latch S1 are attached to each other, the latch holding member S2 is rotated, thereby disengaging with the latch S1, so that the latch S1 can freely rotate. Thus, the latch S1 rotates under the influence of the weight of the working plate P, captured by the latch S1, and therefore, the latch S1 comes out of the slit P2 to capture the latch, so that the working plate P is lowered, and the sash moves down (see Fig.6) .

2nd embodiment

This embodiment relates to the control of the aforementioned motor assembly 300 and includes a contact assembly 100 and a control device 200 for controlling. Below, this embodiment will be described with reference to FIGS. 7-10.

The positioning electrodes 330a or 340a in accordance with the 1st embodiment are made in pairs at a distance from each other, as already described. Thus, the positioning electrodes 330a or 340a are not electrically connected to each other in the normal position, however, the positioning electrodes 330a or 340a are electrically connected to each other by the slider 320 when they are brought into contact with the slider 320.

When the pair of positioning electrodes 330a or 340a are electrically connected to each other, as described above, the control device 200 receives a signal and precisely controls the movement of the plate P by controlling the motor M. The contact unit 100 is configured to transmit a signal to the control device 200.

That is, the contact node 100 is configured to transmit a signal generated from a pair of electrodes 330a or 340a to determine the position in the control device 200, which will be described below with reference to Figs. 8 and 9.

The contact assembly 100 includes positioning terminals 120d and 120e, each of which is electrically connected to a pair of positioning electrodes 330a or 340a, and a contact assembly 110 for housing positioning terminals 120d and 120e.

The housing 110 of the contact node is made with a capacity 111 to accommodate one side of the terminals 120d and 120e for determining the position and opening of their distal ends.

That is, the signal generated when the position determination electrodes 330a and 340a are electrically connected is transmitted to the position determination terminal 120d or 120e and then transmitted to the control device 200.

Moreover, the positioning electrodes 330a and 340a and the positioning terminals 120d and 120e are connected in a well-known manner, which is not described in detail in this document.

Through the contact node 100, as described above, the signal is transmitted to the control device 200. The control device 200 includes electrodes 211d and 211e of the position control device located on the control device body 210 and respectively in contact and electrically connected to the position terminals 120d and 120e, and the electrodes 211d and 211e are connected to the drive C for control.

According to the aforementioned configuration, it is possible to control the vertical movement of the working plate P, which will be described in more detail below.

First of all, when the slider 320 rises to its uppermost position, the slider 320 contacts a pair of electrodes 330a to determine the position mounted on the support plate 330. In this case, the pair of electrodes 330a for determining the position are electrically connected to each other via the slider 320, and the signal is transmitted to pin 120d for positioning. Then, the electrode 211d of the control device for controlling the position in contact with the terminal 120d for determining the position receives a signal and transfers it to the drive C.

As a result, the drive C determines by means of a signal that the slider 320 reaches the highest point from the limit points of movement, and then stops the operation of the motor M.

In accordance with this configuration, it is possible to precisely control the movement of the working plate, thereby preventing the application of excessive load on the electric motor M or reliably raising the window sash.

Meanwhile, the above procedure can be used by analogy in the case when the slider 320 falls to the lowest point.

Moreover, for more reliable control, it is also preferable that the terminals 120a and 120b of the power supply for providing power and a common contact terminal 120c electrically connected to one of the upper electrodes 330a for determining the position and one of the lower electrodes 340a for determining the position are installed together in the housing 110 of the contact node, in addition to the findings 120d and 120e for determining the position, as shown in Fig.8 and 9.

The present invention, made in this way, is described in more detail with reference to FIG. 10.

Figure 10 is a schematic diagram illustrating the principle of signal transmission in accordance with the operation of the contact node 100, the control device 200 and the slider 320.

As shown in FIG. 10, when the slider 320 rises to the uppermost point, the upper positioning electrodes 330a are electrically connected by contact with the slider 320 to transmit a signal to the positioning terminal 120d, and the signal is transmitted to the common terminal 120c. Thus, the position determination terminal 120d and the common terminal 120c are electrically connected to transmit a signal to the position control electrode 211d and the common contact electrode 211c of the control device 200, and the signal is supplied to the drive C to stop the motor M, as described above .

Meanwhile, the control device 200 can be performed in any position if it can be electrically connected to the contact node 100, as described above, and in this embodiment, the control device 200 is attached to a window frame (not shown), as shown in Fig.7 . In addition, the various terminals for determining the position of the contact assembly 100 are electrically connected to the various electrodes 211a, 211b, 211c and 211d of the control device 200 by means of a slot P3 formed on one side of the working plate P.
