Description

Technology Field

[0001] The present invention relates to a device for automatically opening and closing windows, and more specifically, to an improved detachable automatic window opening and closing device that is mounted on a window or door to automatically open and close electrically and maintains automatic opening and closing performance even during long-term use. Background Technology

[0003] Generally, windows are installed on the walls of a building and used for lighting or ventilation inside the building, and may include a window in which transparent or opaque glass is fixed to a window frame, and a window frame installed to be fixed to the wall so that the window slides.

[0004] And the resident opens or closes the windows to ventilate or control the temperature inside the room, and may also adjust the degree of opening of the windows depending on the situation.

[0005] At this time, residents sometimes open and close windows manually, but recently, automatic window opening and closing devices have become widely available.

[0006] For example, an automatic window opening and closing device includes a motor and a cylindrical rubber member that rotates by the motor. This automatic window opening and closing device is fixed to the side of one of two windows that move parallel to each other, and is installed so that the rubber member is in close contact with the glass of the other window.

[0007] Subsequently, when the rubber member rotates by the motor, the window opens or closes by pushing or pulling the glass.

[0008] However, with repeated and prolonged use, the rubber component would wear out or deform due to sunlight and heat, resulting in a significant decrease in the adhesion between the rubber component and the glass. Consequently, the rubber component would slip, causing the window to become impossible to open or close. Prior art literature

[0010] Registered Patent Publication No. 10-0806347 (Published Feb. 29, 2008) Published Patent Publication No. 0-2013-0012271 (Published Feb. 4, 2013) The problem to be solved

[0011] The objective of the present invention is to provide an improved detachable window or door automatic opening and closing device in which a fixed rack and a pinion are set and fixed at a height where they interlock via height setting jigs on the front and side of the window or door, respectively, and the pinion rotates to move the fixed rack, thereby enabling the window or door to open and close accurately without slipping.

[0012] In addition, the objective of the present invention is to provide an improved detachable window or door automatic opening and closing device, wherein a latch member is manufactured to protrude by axial rotation, a locking rack module fixed adjacent to a fixed rack is additionally installed, and the latch member is received or protruded by a pinion to lock or unlock a hinged window or door.

[0013] The technical problems of the present invention are not limited to those mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art from the description below. means of solving the problem

[0015] The performance-improved detachable window or door automatic opening and closing device according to the present invention may include: a fixing module including a hollow fixed frame attached to the side of one window or door; a rack module including a fixed rack attached to the front of another window or door; and a driving module including a housing that is fitted into the fixing frame and is detachably attached, a power source embedded in the housing, and a pinion that rotates by the power source.

[0016] Here, when a drive module is fitted and mounted in the hollow of a fixed frame, the fixed rack and pinion mesh together, and when the rotating body and pinion rotate by a power source, the window or door moves together with the fixed rack meshed with the pinion, allowing the interior room to be opened or closed.

[0017] Additionally, the drive module may further include a rotating body that rotates by a power source and is inserted into and secured to a pinion. Here, the rotating body is a hollow cylinder with a side surface that is convex from both sides toward the center, and a plurality of connecting protrusions are formed on the outer surface at regular intervals in the width direction, and a drive shaft connected to the power source can be inserted and fixed into the hollow.

[0018] In addition, the pinion has a hollow cylindrical shape, and the inner surface of the hollow is convex from both sides toward the center, and a plurality of coupling grooves can be formed on the inner surface of the hollow at regular intervals in the width direction.

[0019] Therefore, due to the convex shape, when the rotating body is press-fitted to the pinion, the coupling projection can be press-fitted into the coupling groove.

[0020] In addition, it may include a fastening member installed to tighten the rotating body by penetrating one edge of the pinion while the rotating body and the pinion are combined.

[0021] For example, the pinion may be a first pinion assembly in which a drive shaft is positioned through the center in the longitudinal direction, and the pinion is a cylindrical shape with a gear formed on its outer surface.

[0022] As another example, the pinion may be a second pinion assembly having a cylindrical shape, a cylindrical shape with multiple inner diameters formed having a large diameter, a medium diameter, and a small diameter, a cover inserted and fixed in the large diameter, and a bearing inserted and fixed in the medium diameter, with a drive shaft positioned through the center in the longitudinal direction.

[0023] Here, the cover is circular on the side and the rim is bent in one direction, a hub of a certain height is formed in the center, and a drive shaft can be positioned passing through the hub.

[0024] Additionally, the rack module may, for example, include a fixed rack of a certain length and an adhesive or adhesive tape attached to the back of the fixed rack. As another example, it may include a fixed rack of a certain length, a rack case attached to at least one of the back or side of the fixed rack and having mounting grooves and mounting protrusions formed on each of its sides, and an adhesive or adhesive tape attached to the back of the rack case. Here, the rack case may be made of a rigid box shape that protects the fixed rack by blocking heat, sunlight, and ultraviolet rays, or a flexible film.

[0025] Additionally, the housing may include a fastening guide portion protruding downwardly from the lower outer surface, a fastening elastic piece positioned between the fastening guide portions and molded to have an elastic tip portion, a fastening projection protruding downwardly from the fastening elastic piece, and a locking projection protruding upwardly from the upper outer surface.

[0026] In addition, it may include a guide groove formed on the lower inner surface of the fixed frame, a fastening projection formed protruding from the front end of the guide groove, and a locking groove formed on the upper inner surface.

[0027] Accordingly, the upper part of the housing is fitted onto the upper part of the fixed frame as the locking projection is engaged in the locking groove, and the lower part of the housing is fitted onto the lower part of the fixed frame as the fastening guide moves along the guide groove and the fastening projection engages with the fastening jaw, thereby allowing the drive module to be mounted on the fixed module. Additionally, since the lower part of the housing moves in a curved manner around the upper part to be fitted onto the fixed frame, the protruding parts in the width direction, including the fastening guide, can form an incline by increasing in thickness from the center of the width toward the outer edge.

[0028] In addition, the fixing frame may be fixed to a fixing plate screwed to the side of the window or door, or attached to the side of the window or door with adhesive or adhesive tape.

[0029] In addition, the present invention may further include a height setting jig for adjusting the height of a drive module or a rack module so that the pinion and the fixed rack engage. Here, as an example, the height setting jig may include a hollow body and an extension protruding outward at the same height from the upper surface of the body. Thus, when the lower surface of the body is pressed against the inner lower surface of the fixed frame and pushed, the end portion of the extension portion can indicate the lower position of the rack module. Alternatively, the height setting jig may include a hollow body, an extension protruding outward at the same height from the upper surface of the body, and a sliding projection protruding downward from the lower surface of the body. Thus, when the sliding projection is inserted into the guide groove of the fixed frame and pushed, the end portion of the extension portion can designate the upper or lower position of the rack module at a window or door.

[0030] As another example, the height setting jig may further include a height setting jig for adjusting the height of a drive module or a rack module so that the pinion and the fixed rack engage. Here, the height setting jig may include a hollow projection case j molded to protrude from the lower outer surface of the fixed frame, and a height setting projection that is inserted into and withdrawn from the projection case. Thus, when the height setting projection is withdrawn, the end portion can specify the upper or lower position of the rack module from a window or door.

[0031] Meanwhile, it may further include a locking rack module comprising: a body fixed to the front of a window or door and having one end portion of the fixed rack fixed to the entire body; a latch unit including a partial rack mounted on the body and axially rotating to be received or protruded; a moving rack unit inserted into the rear end of the body and sliding while rotating the partial rack axially; a stopper mounted on the rear end of the body to prevent the moving rack unit from moving backward and a locking rack module in which the partial rack protrudes by axial rotation to lock or unlock the hinged window or door.

[0032] In a first embodiment, the latch unit may be a first latch unit comprising a latch upper portion through which a rotating bar mounted on the upper portion of the body passes, a spiral groove formed longitudinally on the surface of the latch upper portion, and a first partial rack extending from the lower portion of the latch upper portion. Additionally, the movable rack unit may be a first movable rack unit comprising a long operating bar inserted into the upper portion of the body, a locking projection formed protruding from the middle portion of the operating bar in the longitudinal direction and fitted into the spiral groove, and a second partial rack in the shape of an '┘' extending downward from the lower portion of the operating bar. Accordingly, when the pinion engages with the second partial rack and rotates, the first movable rack unit slides forward and backward, and when the first latch unit rotates downward on an axis, it is received by the body, and when it rotates upward on an axis, it protrudes, thereby locking or unlocking the window or door.

[0033] In a second embodiment, the latch unit may be a second latch unit comprising a first latch bar (561) extending upward from the lower part of the latch, wherein the lower part of the latch is mounted to rotate axially on the body via a rotating bar, a spiral groove is formed on the surface of the lower part of the latch, and the second latch unit comprising a first latch bar (561) extending upward from the lower part of the latch. Additionally, the movable rack unit may be a second movable rack unit comprising a long operating bar inserted into the upper part of the body, a protruding part formed in the middle of the longitudinal direction of the operating bar and fitted into the spiral groove, and a second L-shaped part rack extending downward from the lower part of the operating bar. Accordingly, when the pinion engages with the second part rack and rotates, the second movable rack unit slides forward and backward, and when the second latch unit rotates upward axially, it is received by the body, and when it rotates downward axially, it protrudes, thereby locking or unlocking the window or door.

[0034] In a third embodiment, the latch unit may be a third latch unit comprising a latch upper portion through which a rotating bar mounted on the upper portion of the body passes, a first bevel gear mounted on one side of the rotating bar, and a first partial rack extending from the lower portion of the latch upper portion. Additionally, the movable rack unit may be a third movable rack unit comprising a long operating bar inserted into the upper portion of the body, having an operating bar rack formed at its tip, a second partial rack extending downward from the operating bar, and a bevel gear bar in which an operating bar pinion on one side engages with the operating bar rack and a second bevel gear on the other side engages with the first bevel gear. Accordingly, when the pinion engages with the second partial rack and rotates, the third movable rack unit slides forward and backward, and the third latch unit rotates on an upward and downward axis, being received in or protruding from the body to lock or unlock a window or door.

[0035] In a fourth embodiment, the latch unit may be a fourth latch unit comprising a second latch bar that rotates horizontally around a rotation axis on the upper part of the body and a control bar pinion formed on one side of the rotation axis. Additionally, the movable rack unit may be a fourth movable rack unit comprising a long-shaped control bar inserted into the upper part of the body with a control bar rack formed in the middle, and a second partial rack extending downward from the control bar. Accordingly, when the pinion engages with the second partial rack and rotates, the fourth movable rack unit slides forward and backward, and the fourth latch unit rotates horizontally around the axis to be received in the body or protrude, thereby locking or unlocking the window or door.

[0036] In the fifth embodiment, the latch unit may be a fifth latch unit comprising a first and second link member mounted on the upper part of the body, wherein two bars overlap and are installed to interlock with each other through protrusions and grooves, and both free ends rotate axially, and a control bar pinion formed on the axial rotation portion of the first link member. Additionally, the movable rack unit may be a fourth movable rack unit comprising a control bar that is long in shape and inserted into the upper part of the body, with a control bar rack formed in the middle portion, and a second part rack extending downward from the control bar. Accordingly, when the pinion engages with the second part rack and rotates, the fourth movable rack unit slides forward and backward, and as the first link member rotates horizontally axially, it causes the second link member to rotate horizontally axially, thereby lowering or raising it, allowing it to be received in the body or protrude to lock or unlock the window or door.

[0037] Meanwhile, it may further include an auxiliary rack that is accommodated in the body and positioned between the fixed rack and the second partial rack, and fixed to each other in a block-fit structure. Additionally, the second partial rack may have a step shape of one or two tiers based on a '┘' shape to which the auxiliary rack is block-fitted. Additionally, the first partial rack may have a step shape of one or two tiers based on a '┌' shape to which the auxiliary rack and the second partial rack are block-fitted.

[0038] Additionally, it may further include a sensing bar that is an upper and lower long bar, has a first magnet embedded in the upper part, and is inserted through a slot on the upper surface of the body and then connected to a moving rack unit to move together. Accordingly, as it moves together with the moving rack unit, the first magnet may come close to or move away from a second magnet embedded in the driving module, thereby allowing the driving module to indicate whether it is locked or unlocked.

[0039] Additionally, the control bar can be mounted so that its tip protrudes from the body when the moving rack unit moves in a locked position. Therefore, by pushing the protruding part of the control bar into the body, the lock can be released as the moving rack unit moves. Effects of the invention

[0041] According to the present invention, by using a fixed rack and a pinion to open and close a window or door, accurate opening and closing operations are achieved without slipping, and the phenomenon in which opening and closing cannot be properly performed, such as slipping caused by wear of the rubber member when using the adhesion force of a conventional rubber member, can be prevented.

[0042] In addition, by accurately specifying the attachment height of the fixed rack while the height setting jig is seated on the fixed frame, the pinion mounted on the fixed module will accurately engage with the fixed rack when the fixed module is subsequently mounted on the fixed frame, thereby greatly improving the convenience of the operation.

[0043] In addition, since the outer surface of the rotating body and the inner surface of the pinion are manufactured with a convex shape in the middle, the coupling force increases due to the interference fit when the rotating body is inserted and coupled to the pinion, and due to this shape, it may be very difficult to release the coupling.

[0044] In addition, due to the structure in which the rack case encloses the fixed rack, the rack case protects the fixed rack, which is vulnerable to heat, sunlight, and ultraviolet rays, thereby preventing deformation of the fixed rack.

[0045] In addition, since the fixing frame is secured to the side of the window or door via a fixing plate, it can be fixed more firmly than when directly fastened.

[0046] In addition, by mounting a locking rack module in contact with the fixed rack, it is possible to prevent the window or door from opening after it has been closed. Brief explanation of the drawing

[0049] Hereinafter, preferred embodiments are described in detail with reference to the attached drawings so that those skilled in the art can easily practice the present invention. Furthermore, among the configurations mentioned in the various embodiments, mutually similar configurations and related configurations in each embodiment may be substituted, replaced, or added. However, in describing the operating principles of the preferred embodiments of the present invention in detail, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description is omitted.

[0050] Furthermore, terms such as "include," "equip," "compose," or "have" described below, unless specifically stated otherwise, imply that the relevant component may be inherent; thus, they should be interpreted as allowing for the inclusion of additional components rather than excluding them. Additionally, all terms, including technical or scientific terms, should be interpreted in the sense that is comprehensively understood by those skilled in the art to which the present invention pertains, unless specifically defined otherwise.

[0052] The present invention relates to an automatic opening and closing device for a detachable window or door with improved performance, which can be manufactured to be installed on a hinged window or door to open and close. The automatic opening and closing device may include a fixed module (300) fixed to one of the windows or doors to open and close, a driving module (100) that is detachably attached to the fixed module (300) and has a pinion (140) built in that rotates clockwise or counterclockwise by a power source (120), a rack module (200) that is fixed to an adjacent window or door and includes a fixed rack (220), and a height setting jig (400) that sets the height of the rack module (200) or the fixed module (300).

[0053] And a fixed module (300) can be attached to the side of one window or door, and a rack module (200) can be attached to the front of another window or door, and when a driving module (100) is mounted on the fixed module (300), the pinion (140) can be installed so that it is geared with the fixed rack (220).

[0054] Additionally, the height setting jig (400) is manufactured to be seated on a fixed module (300) that is not equipped with a driving module (100), and can be used so that the bottom of the rack module (200) is positioned at the location indicated by the front end of the height setting jig (400). Accordingly, when the height of the rack module (200) is determined, the height of the fixed module (300) is set, and when the height of the fixed module (300) is determined, the height of the rack module (200) can be set.

[0055] Accordingly, when the pinion (140) is rotated clockwise or counterclockwise by the power source (120), the window or door can be moved to the left or right along with the fixed rack (220) engaged with the pinion (140), thereby opening or closing the interior. Here, the operation of the power source (120) can be performed by a plurality of operation buttons installed on the drive module (100) or by a remote control. To this end, a circuit board for operating the power source (120) may be installed inside the drive module (100).

[0057] Below, we will describe in detail, using an example, a detachable window or door automatic opening and closing device with improved performance configured as described above.

[0058] Window Installation Example

[0059] Hereinafter, the automatic opening and closing device according to the present invention will be described using the case where it is installed in a window as an example.

[0060] The present invention may include a driving module (100), a rack module (200), a fixing module (300), a height setting jig (400), and a control unit, as shown in FIG. 1, for a detachable window or door automatic opening and closing device with improved performance.

[0061] First, as shown in FIGS. 1 to FIGS. 4, the drive module (100) may include a housing (110), a power source (120), a rotating body (130), a pinion (140), and a pinion case (150).

[0062] Here, as shown in FIGS. 1 and 2, the housing (110) has a power source (120), a rotating body (130), and a pinion (140) built inside and can be fitted into a fixed frame (320) that is fixed to the first window (10). As shown in FIGS. 2, the housing (110) may have a locking projection (111) on the upper surface, and as shown in FIGS. 8, a paired fastening guide (112) protruding from the lower surface, a fastening elastic piece (113) formed to have an elastic tip portion located between the fastening guides (112), and a fastening projection (114) protruding downward from the fastening elastic piece (113). Correspondingly, on the upper inner surface of the fixed frame (320), a locking groove (321, see FIG. 7) into which a locking projection (111) is coupled, a guide groove (322) into which a compatible fastening guide (112) is fitted, and a fastening projection (323) at the front end of the guide groove (322) may be formed. Here, as shown in FIG. 8, the fastening guide (112) and the portion protruding in the width direction thus form an inclined surface in which the thickness increases from the center toward the outer edge. This shape may be intended to compensate for the fact that the lower part of the housing (110) is not fitted horizontally into the fixed frame (320), but rather the lower part is fitted in a curved shape with the upper part as the axis.

[0063] Accordingly, the upper part of the housing (110) can first be fitted into the fixed frame (320) by engaging the locking projection (111) and the locking groove (321). Next, the lower part of the housing (110) can be fitted into the fixed frame (320) so that the fastening guide part (112) is seated in the guide groove (322), and then the housing (110) can be fastened to the fixed frame (320) by sliding it forward to engage the fastening projection (114) with the fastening jaw (323) with a 'click' sound. Afterward, the housing (110) can be separated from the fixed frame (320) by flipping the fastening elastic piece (113) upward to release the connection between the fastening projection (114) and the fastening jaw (323), and then pulling the lower part of the housing (110) forward.

[0064] Additionally, as shown in FIGS. 2 and 3, the power source (120) may be mounted inside the housing (110) and installed to rotate the drive shaft (121). This power source (120) may rotate the rotating body (130) mounted on the drive shaft (121). For example, the power source (120) may be a motor or a general device capable of rotating the rotating body (130).

[0065] Additionally, as shown in FIGS. 2, 3, and 4, the rotating body (130) may have a hollow cylindrical shape, a drive shaft (121) inserted and fixed in the hollow, and may include a plurality of connecting protrusions (131) formed at regular intervals on the outer surface. As shown in FIG. 4, the rotating body (130) may have a shape in which the central portion is more convex than the portions on both sides. This is to ensure that the state of being inserted and coupled to the pinion (140) is strongly maintained. As another example, the rotating body (130) may have a hollow rectangular prism shape, and the central portion may be more convex than the portions on both ends of the side, in which case the connecting protrusions (131) may be excluded.

[0066] Accordingly, a pinion assembly can be manufactured by fitting the rotating body (130) into the hollow of the pinion (140) and joining them. At this time, the joining projection (131) can be fitted into the joining groove (141) formed on the inner surface of the pinion (140). As a result, the rotating body (130) and the pinion (140) can be rotated by the drive shaft (121). Here, the 'pinion assembly' may be an assembly including the pinion (140), the rotating body (130), and the drive shaft (121).

[0067] Additionally, as shown in FIGS. 3 and 4, the pinion (140) is a hollow cylindrical shape with a plurality of gears formed on its circumferential surface and may include a plurality of coupling grooves (141) formed at regular intervals on its inner surface. The coupling grooves (141) may be formed such that one side is open and the other side is closed. Also, as shown in FIG. 4, the inner surface of the hollow coupling grooves (141) may have a shape where the central part is concave compared to the side parts. As shown in FIGS. 1 and 2, a portion of the pinion (140) may protrude from the housing (110) to engage with the fixed rack (220), while the remaining portion may be located inside the housing (110). Additionally, the pinion (140) may be made of a hard material capable of generally performing gear action, such as plastic, silicone, or iron.

[0068] Accordingly, the rotating body (130) can be coupled to the pinion (140) by inserting the coupling projection (131) through one side of the opening of the coupling groove (141) and then fitting it to the other side of the closing surface. At this time, the rotating body (130) with a convex center and the pinion (140) with a concave center can be coupled by a press fit. Here, in order to maintain the state in which the rotating body (130) and the pinion (140) are coupled, a fastening member (142) may be further included to tighten the rotating body (130) by penetrating one side edge of the pinion (140).

[0069] Additionally, as shown in FIGS. 1 and 2, the pinion case (150) can be embedded in the housing (110) by being positioned to surround the remaining portion of the pinion (140) located on the inner circumference of the housing (110), in addition to the portion protruding outside the housing (110).

[0070] Next, the rack module (200) may include a rack case (210) and a fixed rack (220), as shown in FIGS. 1, 5 and 6. This rack module (200) may be attached to a glass window (22) or a second frame (21).

[0071] Here, the rack case (210) is formed into a roughly 'U' shape to wrap around both sides and the back of the fixed rack (220), and an adhesive or adhesive tape (213) may be attached to the back. Additionally, when there are multiple fixed racks (220), the rack case (210) may have mounting grooves (211) and mounting protrusions (212) formed on each side to arrange the fixed racks (220) in succession, and as a result, the mounting grooves (211) and mounting protrusions (212) of adjacent rack cases (210) may be mutually coupled so that the fixed racks (220) can be arranged continuously. Of course, the fixed rack (220) and the rack case (210) may be manufactured as a single unit. This rack case (210) is a component that protects the fixed rack (220) by being resistant to heat and sunlight and blocking ultraviolet rays. It may be manufactured in the form of a rigid case or made of a soft film to wrap around at least one of the back and side surfaces of the fixed rack (220). Additionally, the rack case (210) may be manufactured in an L-shape that wraps around the top and back surfaces of the fixed rack (220), as shown in FIG. 6. Accordingly, the rack case (210) may be attached to the glass window (22) of the second window (20) or the second frame (21), as shown in FIG. 1.

[0072] Additionally, at least one side of the fixed rack (220), excluding the side where the gear is formed, may be attached to the rack case (210). This fixed rack (220) may be engaged with the pinion (140). Thus, when the pinion (140) rotates while the fixed rack (220) and the pinion (140) are in a gear-measured state, the first window (10) may move relative to the fixed second window (20), or the second window (20) may move relative to the fixed first window (10). Also, if the fixed rack (220) is made of a hard material capable of generally performing gear action, such as plastic or silicone, or a material including iron that is resistant to heat and sunlight, the rack case (210) may be excluded, and the fixed rack (220) may be directly attached to the glass window (22) or the second frame (21) of the second window (20) by means of an adhesive or adhesive tape (213).

[0073] Next, as shown in FIGS. 1 and 7, the fixed module (300) is fixed to the side of the first frame (11) of the first window (10), and the driving module (100) can be attached and detached. To this end, the fixed module (300) may include a fixed plate (310) and a fixed frame (320).

[0074] Here, the fixing plate (310) is a member for fixing the fixing frame (320) to the side of the first frame (11) of the first window (10) of the drawing, and can be fastened with screws as in FIG. 7, or attached with adhesive tape including adhesive or double-sided tape.

[0075] Additionally, the fixed frame (320) is a member into which the drive module (100) is fitted and fastened, and may have a shape identical or similar to that of the housing (110), for example, a hollow elliptical shape with a long vertical length. The fixed frame (320) may be fastened with screws after one side is in close contact with the fixing plate (310), or may be attached with adhesive or an adhesive tape including double-sided tape. Also, if the fixed frame (320) is directly fixed to the first frame (11), the fixing plate (310) may be excluded. And as shown in FIGS. 7 and 8, the fixed frame (320) may have a locking groove (321) formed on the upper inner surface to be coupled with a locking projection (111) on the upper part of the driving module (100), a guide groove (322) formed in the width direction on the lower inner surface to be fitted with a compatible fastening guide part (112) on the lower part of the driving module (100), and a fastening projection (323) formed at the front end of the guide groove (322).

[0076] Accordingly, the upper part of the housing (110) can first be fitted into the fixed frame (320) by engaging the locking projection (111) and the locking groove (321). Next, the lower part of the housing (110) can be fitted into the fixed frame (320) so that the fastening guide part (112) is seated in the guide groove (322), and then the housing (110) can be fastened to the fixed frame (320) by sliding it forward to engage the fastening projection (114) with the fastening jaw (323) with a 'click' sound. Afterward, the housing (110) can be separated from the fixed frame (320) by flipping the fastening elastic piece (113) upward to release the connection between the fastening projection (114) and the fastening jaw (323), and then pulling the lower part of the housing (110) backward.

[0077] Next, the height setting jig (400) may be a means for setting the attachment height of the rack module (200) so that the fixed rack (220) is accurately engaged with the pinion (140) mounted on the fixed frame (320).

[0078] As shown in FIGS. 9 and 10, this height setting jig (400) may include a hollow main body (410) having a finger insertion hole (411), a sliding projection (420) that protrudes downward from the lower surface of the main body (410) and is seated in the guide groove (322) of the fixed frame (320), and an extension part (430) that protrudes outward at the same height from the upper surface of the main body (410). At this time, the height of the extension part (430) may be such that, as in FIG. 9, when the lower end of the rack module (200) is positioned and attached at a location where the extension part (430) touches the glass window (22) of the first window (10) or the first frame (11), the fixed rack (220) and the pinion (140) are accurately engaged.

[0079] Accordingly, as shown in the left figure of FIG. 9, the thumb or index finger is inserted into the finger insertion hole (411), and the sliding projection (420) is placed in the guide groove (322). Then, the rack module (200) can be attached by pushing it toward the glass window (22) of the second window (20) so that the end of the extension part (430) touches the glass window (22). Of course, the finger may not be inserted into the finger insertion hole (411). Alternatively, the position can be marked while the end of the extension part (430) touches the glass window (22), and the top or bottom of the rack module (200) can be positioned at this position to attach it. For example, in FIG. 9, the bottom of the rack module (200) is positioned. Additionally, the position marking of the rack module (200) marked on the glass window (22) can be marked in multiple places while moving the second window (20) to level the rack module (200). Also, for this position marking, a marking member (not shown) impregnated with water-based ink or black ink can be additionally attached to the end surface of the height setting jig (400) that touches the glass window (22). Thus, the position where the rack module (200) is attached can be marked by moving the second window (20) to which the fixed frame (320) is attached and bringing the height setting jig (400) into contact with the glass window (22) multiple times. Then, when the rack module (200) is attached and the drive module (100) is mounted on the fixed frame (320) from which the height setting jig (400) has been removed, the pinion (140) and the fixed rack (220) can be connected by meshing gears.

[0080] Additionally, as shown in FIG. 11, the height setting jig (400) may include a hollow protrusion case (440) attached to the lower outer surface of the fixed frame (320) and a height setting protrusion (450) inserted into or withdrawn from the hollow of the protrusion case (440). Accordingly, the height setting protrusion (450) inserted into the protrusion case (440) can be pushed out and then brought into contact with the glass window (22) to set the height of the rack module (200). At this time, the height indicated by the height setting protrusion (450) may be the upper or lower height of the rack module (200). For example, in FIG. 11, the lower part of the rack module (200) is positioned. Additionally, the position marking on the glass window (22) by contacting it multiple times as described in the example of FIG. 10, or the content regarding the marking member, may be applied in the same or similar manner.

[0081] Finally, the control unit may include a circuit board for operating the power source (120) of the drive module (100) and rotating the pinion (140) clockwise or counterclockwise, and a remote control for transmitting control signals to the circuit board. In addition, a plurality of operating buttons connected to the circuit board may be installed on the surface of the housing (110) of the drive module (100). Accordingly, when the open or close button of the remote control is pressed, the power source (120) operates and the pinion (140) rotates clockwise or counterclockwise, and the second window (20) moves to the left or right together with the fixed rack (220) engaged with the pinion (140), thereby opening or closing the interior room. Here, if the first window (10) is fixed, the second window (20) moves, and conversely, if the second window (20) is fixed, the first window (10) moves.

[0082] Meanwhile, as shown in FIG. 12, a first pinion assembly (160) can be manufactured by integrally forming the pinion (140), the rotating body (130), and the drive shaft (121) shown in FIG. 3. As a result, there is no need to assemble the pinion (140), the rotating body (130), and the drive shaft (121), and thus no tolerances for each part required during assembly are required, so precision is increased and the convenience of assembly for the worker is improved by eliminating the need for assembly.

[0083] In addition, as shown in FIG. 13, as another embodiment of the pinion assembly, the second pinion assembly (170) may include a pinion (140), a bearing (171), a cover (172), and a drive shaft (121).

[0084] Here, the pinion (140) can be manufactured such that a large diameter, a medium diameter, and a small diameter are formed in three stages from one open side to the other open side, and a drive shaft (121) passes through it. A cover (172) is attached to the large diameter, and one or more bearings (171) can be embedded in the medium diameter.

[0085] Additionally, the cover (172) may be circular in shape on the side, with the rim bent in one direction, and the hub (173) formed in the center that is higher than the height of the bent rim. This cover (172) is fitted and fixed to a large inner diameter portion on one side of the pinion (140), and the hub (173) can hold the drive shaft (121) that is positioned through it.

[0086] Additionally, the bearing (171) is a ball bearing and can be inserted and fixed in the middle inner diameter portion of the pinion (140). Two bearings (171) can be spaced apart from each other. As shown in FIG. 13, the bearing (171) can be a ball bearing.

[0087] Additionally, the drive shaft (121) can be positioned through the pinion (140) and through the hub (173) of the bearing (171) and cover (172).

[0088] Durability and rotational performance can be improved through a structure in which a bearing (171) is embedded inside the pinion (140).

[0089] Meanwhile, as shown in FIGS. 14 and 15, a locking rack module (500) may be further included to prevent the window from opening while the window is closed, and which is arranged in contact with one side of the rack module (200). This locking rack module (500) may include a body (510), a first latch unit (520), a first moving rack unit (530), an auxiliary rack (540), and a sensing bar (550).

[0090] First, the rear end of the fixed rack (220) is fixed to the front left side of the body (510) in the drawing, and the first moving rack unit (530) is inserted into the rear and mounted to slide, and a stopper (511) may be mounted at the rear end to restrict the rightward backward movement of the first moving rack unit (530).

[0091] Additionally, the first latch unit (520) may be mounted on the upper part of the body (510) so as to be inserted or protruded while rotating vertically. This first latch unit (520) may have a latch upper part (522) through which a rotating bar (521) mounted across a concave molded groove on the upper part of the body (510) passes, and a first part rack (523) with a rack gear molded on the lower part. Also, the first latch unit (520) may have a height such that an extension of the second part rack (533), which is '┘' shaped, is located below it, and the left end may be arranged in contact with the fixed rack (220), and the right end may be arranged in contact with the auxiliary rack (540). Such a block-fitting structure is illustrated in FIGS. 16 and FIGS. 17. And on the surface of the upper part of the latch (522), a spiral groove (524) into which the locking projection (532) described later is fitted can be formed in the longitudinal direction.

[0092] Additionally, the first moving rack unit (530) can be inserted into the rear of the body (510) and mounted to slide forward to the left or backward to the right. More specifically, the first moving rack unit (530) may include a long operating bar (531) inserted into the body (510), a locking projection (532) formed to protrude from the middle portion in the longitudinal direction of the operating bar (531) and fitted into the spiral groove (524) of the first latch unit (520) to be fastened, and a second part rack (533) that extends downward from the lower part of the operating bar (531) and has a shape of approximately '┘' in the front. At this time, the elongated lower portion of the second part rack (533) may be positioned at the lower part of the first latch unit (520) and the auxiliary rack (540). Also, as shown in Figures 17 and 19, the control bar (531) is fitted into the upper part of the body (510), and the lower part of the second part rack (533) is fitted into the lower part of the body (510), so that the first moving rack unit (530) can slide forward and backward while mounted on the body (510).

[0093] Accordingly, the first moving rack unit (530) can slide forward or backward in the body (510) when the pinion (140) engaged with the second part rack (533) rotates forward or backward. As shown in FIGS. 16 and 17, when moving backward to the right, the first moving rack unit (530) moves away from the fixed rack (220), and the first latch unit (520) rotates downward on the axis by the interlocking of the locking projection (532) and the spiral groove (524) and is received in the body (510), and the entire operating bar (531) can be received inside the body (510). In this state, the first window (10) can be opened. Also, as shown in FIGS. 18 and 19, when moving forward to the left, the first moving rack unit (530) comes closer to the fixed rack (220), and the first latch unit (520) rotates upward on an axis by means of the interlocking of the locking projection (532) and the spiral groove (524), protruding from the body (510) and blocking the fixed module (300), and the tip portion of the operating bar (531) can protrude to the outside of the body (510). In this state, the opening of the first window (10) can be prevented.

[0094] Here, when the protruding operating bar (531) is pushed into the body (510) by an external force, the first moving rack unit (530) moves backward, and the first latch unit (520) can be rotated downward to be received into the body (510). That is, the window can be opened after manually unlocking the first moving rack unit (530). 100

[0095] Additionally, an auxiliary rack (540) may be installed to facilitate block alignment between a sliding first moving rack unit (530) and a vertically rotating first latch unit (520). As shown in FIGS. 15, 17, and 19, this auxiliary rack (540) has a shape of approximately '┘' in the front view, is aligned with the first latch unit (520) in a block-aligning manner, and can be fixed to the body (510). At this time, for alignment with the auxiliary rack (540), the first latch unit (520) may have a shape in which the lower right corner of a square is cut off in the front view. An extension of the second part rack (533) can be positioned and moved below the aligned first latch unit (520) and the auxiliary rack (540).

[0096] And as shown in FIGS. 15 and 20, the sensing bar (550) is in the shape of an upper and lower long bar, and the upper part has a first magnet (551) embedded therein, and the lower part is inserted through a slot (525) formed on the upper right side of the body (510) and then connected to the first moving rack unit (530) so as to be installed to move together with the first moving rack unit (530). Accordingly, when the sensing bar (550) moves away from the fixed rack (220) together with the first moving rack unit (530), the first magnet (551) and the second magnet (115) embedded in the driving module (100) move away from each other, and as a result, the first latch unit (520) rotates downward on the axis, so that the driving module (100) can indicate with a light that the window is in a state where it can be freely opened, allowing the user to visually confirm this. Additionally, when the sensing bar (550) approaches the fixed rack (220) together with the first moving rack unit (530), the first magnet (551) and the second magnet (115) come closer together, and the first latch unit (520) rotates upward to indicate a locked state where the window is prevented from opening, which can be visually confirmed by the user through a light from the driving module (100).

[0097] Meanwhile, the locking rack module (500) can be manufactured in various embodiments. In the various embodiments below, identical or similar components, such as the sensing bar (550), rotating bar (521), spiral groove (524), etc., which are modified structures from the first embodiment, are given the same reference numerals, and the fastening method and structure of each component are replaced by the above description, while the modified or new components are described in detail.

[0098] First, looking at the second embodiment of FIGS. 21 and FIGS. 22, the locking rack module (500) can be manufactured such that when a latch unit is mounted on the upper part of the body (510) and rotates downward, the window is locked. To explain in detail, the locking rack module (500) may include a body (510), a second latch unit (560), and a second moving rack unit (570).

[0099] Here, the upper left side of the body (510) protrudes convexly upward, and a second latch unit (560) can be mounted on this part to rotate up and down on an axis.

[0100] Additionally, the second latch unit (560) may be mounted so that the lower part of the latch rotates axially on the body (510) via a rotating bar (521), and a spiral groove (524) is formed on the surface of the lower part of the latch, and may include a first latch bar (561) that extends upward from the lower part of the latch.

[0101] Additionally, the first moving rack unit (530) may include a control bar (531), a locking projection (532) formed in the longitudinal middle portion of the control bar (531), and a second part rack (533) that extends in a 'L' shape from the lower portion of the control bar (531). The first moving rack unit (530) is installed to slide and be inserted from the right side of the body (510), and backward movement to the right may be restricted by a stopper (511). The control bar (531) may be fitted into the upper portion of the body (510), and the lower portion of the second part rack (533) may be fitted into the lower portion of the body (510). At this time, the auxiliary rack (540) may be excluded due to the 'L' shape of the second part rack (533). Also, since the first latch bar (561) is received by rotating upward on the axis, the second part rack (533) may be a perfect rectangle in the front view.

[0102] Accordingly, when the first moving rack unit (530) moves backward to the right, the first latch bar (561) rotates upward on an axis by the linkage of the locking projection (532) and the spiral groove (524) and is received in the body (510), thereby unlocking the window, and when it moves forward to the left, the first latch bar (561) rotates downward on an axis by the linkage of the locking projection (532) and the spiral groove (524) and protrudes from the body (510), thereby locking the window.

[0103] Here, the driving module (100) illustrated in FIG. 22 is a modified example of the driving module (100) of FIG. 2 and may further include a driving button (116) for 'open' and 'close' on the top. Depending on the locking state of the window, a light may be displayed on the driving button (116) for 'open' or 'close', which can provide convenience for the user in recognizing the locking state and selecting the operation.

[0104] Next, looking at the third embodiment of the locking rack module (500) illustrated in FIG. 23, the structure may be such that the latch unit is rotated axially using a bevel gear and a rack pinion gear. To explain in detail, the locking rack module (500) may include a body (510), a third latch unit (580), and a third moving rack unit (590).

[0105] Here, the body (510) is identical or similar to the first embodiment, so the above description is substituted.

[0106] Additionally, the third latch unit (580) is mounted so that its upper portion rotates axially on the upper portion of the body (510) via a rotating bar (521), and a first portion rack (523) can be formed on its lower portion. Here, a first bevel gear (582) can be mounted on one side of the rotating bar (521).

[0107] Additionally, the third moving rack unit (590) may include an upper operating bar (531), a second part rack (533) extending downward from the operating bar (531) in a frontal two-step stepped shape with an approximate '┘' shape, and a bevel gear bar (591).

[0108] The operating bar (531) may have an operating bar rack (534) formed on the front end of the third latch unit (580).

[0109] The second part rack (533) may have a shape of approximately '┘' in the front view and a two-step stepped shape. The shapes of the first part rack (523) and the auxiliary rack (540) of the first latch unit (520) may be modified to conform to this shape. Of course, the first part rack (523), the second part rack (533), and the auxiliary rack (540) may have the single-step stepped shape of FIG. 15.

[0110] Additionally, the bevel gear bar (591) may include a control bar pinion (592) formed to be gear-coupled with a control bar rack (534) on one side, and a second bevel gear (593) formed to be gear-coupled with a first bevel gear (582) on the other side.

[0111] Accordingly, when the operating bar (531) slides forward and backward, the first latch unit (520) can rotate vertically by means of the operation of the operating bar rack (534), the operating bar pinion (592), the first bevel gear (582), and the second bevel gear (593).

[0112] Next, looking at the fourth embodiment of the locking rack module (500) illustrated in FIG. 24, it may be a structure that rotates the bar horizontally on an axis using a rack panion gear. To explain in detail, the locking rack module (500) may include a body (510), a fourth latch unit (600), and a fourth moving rack unit (610).

[0113] Here, the body (510) is identical or similar to the first embodiment, so the above description is substituted.

[0114] Additionally, the fourth latch unit (600) may include a second latch bar (601) installed to be received or protruded from the upper part of the body (510) while rotating horizontally through a rotation axis, and an operating bar pinion (592) formed on the upper part of the rotation axis.

[0115] Additionally, the fourth moving rack unit (610) may include an upper operating bar (531), a second part rack (533) extending downward from the operating bar (531) in a frontal shape of approximately '┘', and an operating bar rack (534) formed in the middle portion with respect to the longitudinal direction from the operating bar (531).

[0116] Accordingly, when the control bar (531) slides forward and backward, the latch bar (561) can rotate horizontally on an axis by means of the interlocking of the control bar rack (534) and the control bar pinion (592).

[0117] Finally, looking at the fifth embodiment of the locking rack module (500) illustrated in FIG. 25, it may be a structure in which two link bars are interlocked and erected using a rack and pinion gear. To explain in detail, the locking rack module (500) may include a body (510), a fifth latch unit (620), and a fourth moving rack unit (610).

[0118] Here, the body (510) is identical or similar to the first embodiment, so the above description is substituted.

[0119] Additionally, the fifth latch unit (620) may include a first link member (621) and a second link member (622) mounted on the upper part of the body (510) such that two bars of different lengths overlap and are connected by protrusions and grooves, and both ends of which are free ends that rotate axially, and an operating bar pinion (592) formed on the axial rotation portion of the first link member (621).

[0120] Additionally, the fourth moving rack unit (610) may include an upper operating bar (531), a second part rack (533) extending downward from the operating bar (531) in a frontal shape of approximately '┘', and an operating bar rack (534) formed in the middle portion with respect to the longitudinal direction from the operating bar (531).

[0121] Accordingly, when the control bar (531) slides forward and backward, the first link member (621) and the second link member (622) rotate horizontally along the axis through the linkage of the control bar rack (534) and the control bar pinion (592), and can be set up in an approximately 'ㅅ' shape.

[0123] As explained above, a person skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
