Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to a lifting door and window system. Background Art

[0002] This section only provides background information related to the present application to help those skilled in the art understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] The existing lifting door and window system on the market uses the principle of lever theory. By rotating the handle, the transmission device is driven to move, and then the pulley mechanism set at the bottom of the door leaf is driven to lift or lower the door leaf, thereby achieving the lifting or sinking of the door leaf. Among them, the handle and the transmission device are usually installed on the visible surface (front) of the leaf frame, which results in a wider visible surface of the leaf frame, which not only makes the field of view of the door leaf narrower, but also reduces the aesthetics of the door leaf. In addition, the existing locking components are usually integrated on the transmission device, which results in a more complex structure of the transmission device, and also increases the volume of the transmission device, thereby increasing the width of the leaf frame profile.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0062] See also Figure 1-19 The utility model provides a lifting door and window system, including a door leaf 1, a handle assembly 2, a side-mounted transmission 3, a pulley mechanism 4 and a locking transmission assembly 5, the door leaf 1 includes a leaf body 11 and a leaf frame 12; the handle assembly 2 and the side-mounted transmission 3 are both arranged on the left side of the leaf frame 12; the handle assembly 2 includes a handle 21, the side-mounted transmission 3 includes a first transmission assembly and a first transmission bar 35, the handle 21, the first transmission assembly and the first transmission bar 35 are sequentially connected in transmission; the pulley mechanism 4 is arranged at the bottom of the leaf frame 12 and includes a front lifting pulley group 41 and a rear lifting pulley group 42 arranged in a front-to-back interval, the front lifting pulley group 41 and the rear lifting pulley group 42 are connected by a connecting rod 43; the front lifting pulley group 41 is connected in transmission with the first transmission bar 35; the locking transmission assembly 5 is arranged on the right side of the leaf frame 12 and includes a second transmission bar 51, and the second transmission bar 51 is connected in transmission with the rear lifting pulley group 42.

[0063] Therefore, by arranging the handle assembly 2 and the side-mounted transmission 3 on the same side of the sash frame 12, the visible surface of the sash frame 12 can be narrowed, thereby improving the aesthetics of the door leaf 1; in addition, by arranging the locking transmission assembly 5 on the other side of the sash frame 12, the structure of the side-mounted transmission 3 is simplified, and the layout of the door and window accessories is made more reasonable.

[0064] See also Figure 3-5 The locking transmission assembly 5 also includes a second transmission panel 52 and a locking point 53, and the locking point 53 is used to be fixed on a door frame (not shown in the figure); the second transmission bar 51 is slidably arranged in the second transmission panel 52, and a avoidance hole for the locking point 53 to extend into is provided on the second transmission panel 52; a locking hole 511 connected to the avoidance hole is provided on the second transmission bar 51, and when the second transmission bar 51 is driven to move until the locking hole 511 and the locking point 53 are clamped or released, the door leaf 1 is locked or released with the door frame.

[0065] Specifically, the locking hole 511 includes a flaring portion 5111, a contraction portion 5112 and a clamping portion 5113, the widths of which decrease successively. When the second transmission bar 51 is driven to move until the locking point 53 is located at the flaring portion 5111, the locking hole 511 and the locking point 53 are loosened. When the locking point 53 passes through the contraction portion 5112 and is clamped with the clamping portion 5113, the locking hole 511 and the locking point 53 are clamped.

[0066] See also Figure 6-12 The first transmission assembly includes an eccentric wheel 32 and a slider 33. The side-mounted transmission device 3 also includes a box body 31. The eccentric wheel 32 is rotatably arranged in the box body 31 and includes a main shaft 321, an eccentric shaft 322 arranged on one side of the main shaft 321 and offset from the center thereof, and a transmission shaft 323 arranged on the other side of the main shaft 321. The transmission shaft 323 passes through the box body 31 and is connected to the handle 21. The slider 33 is slidably arranged in the box body 31 and is provided with a slide groove 331 matching the eccentric shaft 322. The eccentric shaft 322 is arranged in the slide groove 331 and can slide along the slide groove 331. One end of the first transmission bar 35 is connected to the slider 33, and the other end thereof passes through the box body 31 and is transmission-connected to the front lifting pulley set 41. Preferably, the main shaft 321, the eccentric shaft 322 and the transmission shaft 323 are all integrally formed, and the structure is more stable and has higher strength.

[0067] Therefore, when the handle 21 is rotated, the eccentric wheel 32 can be driven to rotate, and the sliding block 33 can be driven to slide through the sliding cooperation between the eccentric shaft 322 and the sliding groove 331, thereby driving the first transmission bar 35 to move, and finally driving the front lifting pulley group 41 to move.

[0068] Furthermore, the side-mounted transmission 3 also includes a reversing positioning mechanism 34 arranged on the slider 33, and the reversing positioning mechanism 34 includes a gear 341 and a first rack 342 and a second rack 343 which are arranged on both sides of the gear 341 and meshed with it for transmission, and the slide groove 331 is provided with a first through hole 3311 and a second through hole 3312 which respectively connect the first rack 342 and the second rack 343. Therefore, when the gear 341 is driven to rotate, the first rack 342 and the second rack 343 can be driven to move in opposite directions, the first rack 342 can pass through the first through hole 3311 and extend into the slide groove 331, and the second rack 343 can pass through the second through hole 3312 and extend into the slide groove 331; when the first rack 342 or the second rack 343 extends into the slide groove 331, they can both abut against the eccentric shaft 322 to limit the rotation direction of the eccentric wheel 32, thereby limiting the rotation direction of the handle 21.

[0069] Therefore, the side-mounted transmission device 3 of the utility model can be used in conjunction with the side-mounted handle 21. When the handle 21 is rotated, it can sequentially drive the first transmission bar 35 to move up and down through the transmission cooperation of the eccentric wheel 32 and the slider 33. It has a simple structure, convenient operation, and strong practicality. In addition, by setting the reversing positioning mechanism 34, when the side-mounted transmission device 3 is installed on the left or right side of the fan frame 12, the first rack 342 or the second rack 343 can be selected to extend into the slide groove 331 and abut against the eccentric shaft 322 by rotating the gear 341, thereby limiting the rotation direction of the eccentric wheel 32, thereby realizing the left and right assembly of the side-mounted transmission device 3, so that there is no need to design two specifications and styles, which greatly improves its applicability and reduces costs.

[0070] Specifically, a mounting cavity 311 is provided on the box body 31, and the eccentric wheel 32 is rotatably arranged in the mounting cavity 311; the slider 33 is slidably arranged in the mounting cavity 311, and the left and right side walls of the slider 33 are respectively fitted with the left and right side walls of the mounting cavity 311; the slide groove 331 is extended along the left and right directions, and when the eccentric wheel 32 is driven to rotate, the eccentric shaft 322 can slide with the slide groove 331 to drive the slider 33 to slide up and down in the mounting cavity 311, thereby driving the first transmission bar 35 to slide up and down.

[0071] Furthermore, the side-mounted transmission 3 further includes a positioning cover 38, a third mounting groove 334 is provided on the slider 33, the reversing positioning mechanism 34 is arranged in the third mounting groove 334 and is covered on the third mounting groove 334 by the positioning cover 38 to restrict the reversing positioning mechanism 34 to move in the third mounting groove 334; in addition, it also includes a cover plate 36 covered on the box body 31, the cover plate 36 presses the eccentric wheel 32 and the slider 33 to restrict both of them in the mounting cavity 311; the cover plate 36 is provided with a clearance hole 361, and the gear 341 is provided with an adjustment part 3411, preferably, the adjustment part 3411 is a boss provided on the gear 341, and the boss passes through the positioning cover 38 and extends out of the clearance hole 361. Among them, the boss is provided with an adjustment hole, and the user can insert a screwdriver into the adjustment hole and rotate it to drive the gear 341 to rotate.

[0072] In this embodiment, mounting columns 312 are respectively provided at the four corners of the mounting cavity 311 on the box body 31, and third through holes 362 are respectively opened on the cover plate 36 at positions corresponding to the mounting columns 312. The cover plate 36 and the box body 31 can be connected by bolts passing through the third through holes 362 and fixed on the mounting columns 312.

[0073] More specifically, a first mounting groove 332 is formed on the slider 33 , one end of the first transmission bar 35 is inserted into the first mounting groove 332 and the two are connected by a locking screw 392 to achieve fixation.

[0074] Furthermore, the side-mounted transmission device 3 also includes a first transmission panel 37 connected to the box body 31, and a cavity is opened in the first transmission panel 37. The other end of the first transmission bar 35 passes through the box body 31 and extends into the cavity, and the left and right side walls of the first transmission bar 35 are respectively fitted with the left and right side walls of the concave cavity, thereby limiting the first transmission bar 35 to move up and down only in the concave cavity.

[0075] Furthermore, the side-mounted transmission device 3 further includes a booster spring 391. The slider 33 is further provided with a second mounting groove 333. The booster spring 391 is disposed in the second mounting groove 333 and one end of the booster spring 391 abuts against the slider 33 and the other end abuts against the box body 31. Preferably, two booster springs 391 are provided and are spaced apart from each other in the left-right direction.

[0076] When the side-mounted transmission device 3 of the present application is used, since the lower end of the first transmission bar 35 is connected to the pulley mechanism 4, when the first transmission bar 35 is driven to move up and down, the pulley mechanism 4 can be driven to lift or lower, thereby driving the door leaf 1 to rise or sink. Since the weight of the door leaf 1 is large, when the handle 21 is turned to drive the door leaf 1 to rise, the booster spring 391 can release the elastic force to drive the door leaf 1 to rise, so that there is no need to use a large force to turn the handle 21, which is more convenient.

[0077] See also Figure 9-12 The working principle of the side-mounted actuator 3 of the utility model is as follows:

[0078] When the side-mounted transmission device 3 is installed on the left side of the fan frame 12, the gear 341 is rotated to drive the first rack 342 to pass through the first through hole 3311 and extend into the slide groove 331. At this time, the eccentric wheel 32 can be restricted to rotate on the right side, that is, the handle 21 can be restricted to rotate only on the right side; when the handle 21 is driven to rotate on the right side, the eccentric shaft 322 can be slidably matched with the slide groove 331 to drive the slider 33 to move up and down, and then the first transmission bar 35 moves up and down. Figure 9-10 shown.

[0079] When the side-mounted transmission device 3 is installed on the right side of the fan frame 12, the gear 341 is rotated to drive the second rack 343 to pass through the second through hole 3312 and extend into the slide groove 331. At this time, the eccentric wheel 32 can be restricted to rotate on the left side, that is, the handle 21 can be restricted to rotate only on the left side. When the handle 21 is driven to rotate on the left side, the eccentric shaft 322 can be slidably matched with the slide groove 331 to drive the slider 33 to move up and down, and then the first transmission bar 35 moves up and down. Figure 11-12 shown.

[0080] Therefore, the side-mounted transmission device 3 of the present application can be used for both left and right assembly, thereby improving its applicability and reducing costs.

[0081] See also Figure 13-17 The front lifting pulley block 41 and the rear lifting pulley block 42 have the same structure and both include a lifting seat 411, a pulley assembly 412 and a second transmission assembly. The lifting seat 411 is connected to the bottom corner of the sash frame 12; the pulley assembly 412 is movably matched with the lifting seat 411; one end of the second transmission assembly is transmission-connected to the first transmission bar 35 or the second transmission bar 51, and the other end thereof is transmission-connected to the pulley assembly 412. When the pulley assembly 412 is driven to lift or lower, the door leaf 1 can be driven to lift or sink.

[0082] Among them, the pulley assembly 412 includes two fixed plates 4121 respectively arranged on the left and right sides of the lifting seat 411 and two bearing pulleys 4122 clamped and connected between the two fixed plates 4121 and arranged at intervals in the front and back, and the bearing pulley 4122 is used to slide on the slide rail 6; the bearing pulley 4122 includes a pulley disc 41221 and a double-row ball bearing 41222 arranged in the pulley disc 41221, and the bearing pulley 4122 passes through the double-row ball bearing 41222 through a fixing pin 4123 to be fixed on the fixed plate 4121.

[0083] Therefore, the bearing pulley 4122 made of double-row ball bearings 41222 can be further reduced in size while ensuring the same load-bearing capacity as a large-size pulley, thereby narrowing the visible surface of the bottom profile of the sash frame 12, making it more simple and beautiful, thereby achieving a better visual effect.

[0084] In this embodiment, a first fixing hole 41211 for fixing and cooperating with the end of the fixing pin 4123 is defined on the fixing plate 4121 .

[0085] Furthermore, the lifting seat 411 includes a seat body 4111 and a mounting plate 4112 disposed on the seat body 4111. The mounting plate 4112 is an L-shaped structure and includes a horizontal plate portion 41121 and a vertical plate portion 41122. The horizontal plate portion 41121 is fixed to the seat body 4111. The horizontal plate portion 41121 and the vertical plate portion 41122 are both provided with a plurality of mounting holes for mounting on the fan frame 12. In addition, a guide groove 41111 is provided on the seat body 4111. A guide shaft 4124 is provided on the pulley assembly 412, which is clamped and connected between the two fixing plates 4121 and matches the guide groove 41111. The guide shaft 4124 is passed through the guide groove 41111 and can slide along the guide groove 41111. Therefore, when the pulley assembly 412 is driven to rise or sink, the door leaf 1 can be driven to rise or sink through the sliding cooperation between the guide shaft 4124 and the guide groove 41111.

[0086] Among them, when the guide shaft 4124 sinks to the lowest end of the guide groove 41111, the pulley assembly 412 completes the sinking action, and the door leaf 1 completes the lifting action. At this time, the bearing pulley 4122 contacts the slide rail 6; when the guide shaft 4124 rises to the top of the guide groove 41111, the pulley assembly 412 completes the lifting action, and the door leaf 1 completes the sinking action. At this time, the bottom of the lifting seat 411 abuts against the slide rail 6, and the bearing pulley 4122 separates from the slide rail 6.

[0087] Furthermore, it also includes a pulley rest block 418 disposed at the bottom of the seat body 4111. The pulley rest block 418 includes a main body portion that matches the shape of the slide rail 6 and a plug strip disposed on the main body portion. A plug hole is provided at the bottom of the seat body 4111. The plug strip is plugged into the plug hole to achieve connection between the two. Therefore, when the door leaf 1 completes the sinking action, the main body of the pulley rest block 418 contacts the slide rail 6, and the door leaf 1 cannot be driven to move, thereby improving the stability of the door leaf 1.

[0088] Preferably, the pulley rest block 418 is made of nylon, thereby increasing the contact friction between it and the slide rail 6.

[0089] In this embodiment, a third fixing hole 41213 for cooperating and fixing with the end of the guide shaft 4124 is defined on the fixing plate 4121 .

[0090] Furthermore, the second transmission assembly includes a first connecting rod 414, an adapter 413 and a second connecting rod 415, and the adapter 413 is hinged to one end of the first connecting rod 414, the base body 4111 and one end of the second connecting rod 415 respectively; the other end of the first connecting rod 414 is connected to the first transmission bar 35 or the second transmission bar 51, and the first connecting rod 414 is slidably disposed on the vertical plate portion 41122 of the mounting plate 4112; the other end of the second connecting rod 415 extends between the two fixed plates 4121, and the second connecting rod 415 and the fixed plate 4121 are connected and fixed by a fixing pin 4123.

[0091] Therefore, when the first connecting rod 414 is driven to slide upward on the vertical plate portion 41122, the adapter 413 can be driven to rotate, thereby driving the second connecting rod 415 and the fixed plate 4121 to sink toward the front side. The movement of the fixed plate 4121 will synchronously drive the bearing pulley 4122 and the guide shaft 4124 to sink toward the front side until the bearing pulley 4122 contacts the slide rail 6. At this time, the bearing pulley 4122 does not move, and the guide shaft 4124 continues to sink and drive the door leaf 1 to lift by cooperating with the guide groove 41111 until the guide shaft 4124 slides to the lowest end of the guide groove 41111. At this time, the door leaf 1 completes the lifting action, and the pulley rest block 418 is separated from the slide rail 6.

[0092] Similarly, when the first connecting rod 414 is driven to slide downward on the vertical plate portion 41122, the adapter 413 can be driven to rotate in the opposite direction, thereby driving the second connecting rod 415 and the fixed plate 4121 to perform a lifting action in the rear direction. The movement of the fixed plate 4121 will synchronously drive the bearing pulley 4122 and the guide shaft 4124 to perform a lifting movement in the rear direction, and drive the door leaf 1 to sink through the cooperation between the guide shaft 4124 and the guide groove 41111 until the pulley rest block 418 abuts against the slide rail 6. At this time, the bearing pulley 4122 is driven to be lifted and detached from the slide rail 6 until the guide shaft 4124 slides to the top of the guide groove 41111, and the door leaf 1 completes the sinking action.

[0093] In this embodiment, the first connecting rod 414 is provided with a fifth hinge hole 4141, the adapter 413 is provided with a third hinge hole 4132, and the two are connected by a latch 416 to achieve a hinged connection; the base body 4111 is provided with a first hinge hole 41112, the adapter 413 is provided with a second hinge hole 4131, and the two are connected by a latch 416 to achieve a hinged connection; the second connecting rod 415 is provided with a sixth hinge hole 4151, the adapter 413 is provided with a fourth hinge hole 4133, and the two are connected by a latch 416 to achieve a hinged connection; the other end of the second connecting rod 415 is provided with a fifth fixing hole 4152, the fixing plate 4121 is provided with a second fixing hole 41212, and the two are connected by a fixing pin 4123 to achieve a fixed connection.

[0094] Furthermore, it also includes a connector 417 disposed at the other end of the pulley assembly 412, and the connector 417 is clamped and fixed between the two fixing plates 4121; specifically, the left and right sides of the connector 417 are provided with a boss 4171, and the fixing plate 4121 is provided with a fourth fixing hole 41214, and the boss 4171 is inserted into the fourth fixing hole 41214 and clamped and fixed to achieve the connection between the two. Therefore, by providing the connector 417, it can be connected with the connecting rod 43 to achieve the connection and fixation between the front lifting pulley group 41 and the rear lifting pulley group 42.

[0095] Furthermore, it also includes a slide rail box 7 arranged under the door leaf 1, the slide rail 6 is arranged inside the slide rail box 7, and the pulley mechanism 4 at least partially extends into the slide rail box 7 and is slid on the slide rail 6 through the bearing pulley 4122. Therefore, the slide rail box 7 can shield the pulley mechanism 4 to achieve "hiding" of the pulley mechanism 4, thereby improving the overall aesthetics of the door and window system.

[0096] When the guide shaft 4124 is driven to slide to the top of the guide groove 41111, the door leaf 1 completes the sinking action and is pressed on the slide rail box 7. At the same time, the bottom of the lifting seat 411 abuts against the slide rail 6 through the pulley rest block 418, and the bearing pulley 4122 is separated from the slide rail 6. At this time, the door leaf 1 cannot move. Fig.18 As shown; when the guide shaft 4124 is driven to slide to the lowest end of the guide groove 41111, the door leaf 1 completes the lifting action and disengages from the slide rail box 7, and at the same time, the pulley rest block 418 on the lifting seat 411 disengages from the slide rail 6, and the bearing pulley 4122 contacts the slide rail 6. At this time, pushing the door leaf 1 can drive the door leaf 1 to move left and right, as shown in FIG. Fig.19 shown.

[0097] In summary, the utility model provides a lifting door and window system, which can narrow the visible surface of the sash frame 12 by arranging the handle assembly 2 and the side-mounted actuator 3 on the same side of the sash frame 12, thereby improving the aesthetics of the door leaf 1; in addition, by arranging the locking actuator assembly 5 on the other side of the sash frame 12, the structure of the side-mounted actuator 3 is simplified, and the layout of the door and window accessories is made more reasonable.
