Description

Technical Field

[0001] The present invention relates to the technical field of door and window parts, and in particular to a stepless climbing device for doors and windows. Background Art

[0002] In modern architecture, aluminum alloy doors and windows are widely used in engineering projects. During long-term use, aluminum alloy doors and windows may experience corner loss, which will affect the overall sealing and waterproofing performance, and even affect the normal opening and closing of doors and windows.

[0003] Currently, the solution to corner drop on doors and windows is to use a climbing block. The climbing block is a wedge-shaped component installed on the inside of the window frame, at the bottom of the window sash. When the window sash is closed, it rises along the inclined surface of the climbing block, allowing the window to open and close normally. However, because the height difference of each climbing block is fixed, different climbing blocks are required for doors and windows of different sizes and degrees of corner drop. Climbing blocks are not very versatile. In addition, when closing the window sash, there is high friction between the climbing block and the window sash, which produces a loud noise. It requires a lot of force to close the window sash, and the climbing block is prone to wear. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems in the prior art. To this end, the present invention provides a stepless climbing device for doors and windows.

[0005] According to an embodiment of the present invention, a stepless climbing device for doors and windows includes a positioning seat and a climbing assembly, the positioning seat is provided with an abutting portion, the abutting portion has a first abutting surface and a second abutting surface, the orientation of the first abutting surface located at the abutting portion is the front side, and the second abutting surface is located at the top of the abutting portion; the climbing assembly includes a climbing seat and a supporting plate, the top of the supporting plate is hinged to the climbing seat, and the hinge shaft at the hinge is called the first hinge shaft, the first hinge shaft is arranged horizontally, the bottom of the supporting plate is provided with a notch, the supporting plate has a first edge and a second edge, the first edge is arranged at the front side of the notch, and the second edge is arranged at the top of the notch, the first edge is adapted to the first abutting surface, and the second edge is adapted to the second abutting surface.

[0006] The stepless climbing device for doors and windows according to the embodiment of the present invention has at least the following technical effects: when in use, the positioning seat can be installed on the window frame, and the climbing seat can be installed on the window sash; when closing the window sash, the supporting piece can be rotated first to make the missing corner abut against the abutment part, and then the window sash can be closed continuously, and the supporting piece will rotate around the first hinge shaft and lift the window sash to achieve the purpose of lifting the window sash; by adjusting the installation position of the positioning seat and the climbing seat, it can be suitable for doors and windows of different sizes and different degrees of corner drop, and has good versatility; in the process of closing the window sash, the friction between the abutment part and the supporting piece is small, which reduces abnormal noise and saves more effort.

[0007] In some embodiments of the present invention, the positioning seat is provided with a mounting portion, the mounting portion being located at the bottom of the positioning seat, and the abutting portion having two third abutting surfaces, the two third abutting surfaces being located on the left and right sides of the abutting portion, respectively. The mounting portion can be used to connect the positioning seat to the window frame, so that the positioning seat can be installed on the bottom beam of the window frame, or on the left or right beam of the window frame. The positioning seat can be installed in an appropriate position according to the user's needs, providing greater versatility.

[0008] In some embodiments of the present invention, the mounting portion is a strip-shaped protrusion, the bottom of the strip-shaped protrusion is provided with a first convex edge, the abutting portion is provided with a first internally threaded through hole, and the first internally threaded through hole is inclined; the strip-shaped protrusion is transversely arranged at the front bottom of the abutting portion, the first convex edge protrudes forward from the strip-shaped protrusion, and the first internally threaded through hole faces the rear bottom of the abutting portion; or the strip-shaped protrusion is transversely arranged at the rear bottom of the abutting portion, the first convex edge protrudes backward from the strip-shaped protrusion, and the first internally threaded through hole faces the front bottom of the abutting portion. When installing the positioning seat on the window frame, the first convex edge can be first embedded in one side of the groove of the window frame, and then a set screw can be used to pass through the first internally threaded through hole and abut against the other side of the groove of the window frame, thereby completing the installation of the positioning seat. The structure is simple and the installation operation is easy.

[0009] In some embodiments of the present invention, the positioning seat is provided with a first vertical through hole. By providing the first through hole, when installing the positioning seat, a self-tapping screw can be passed through the first through hole and screwed into the window frame to complete the installation of the positioning seat, resulting in a simple structure and easy installation.

[0010] In some embodiments of the present invention, the climbing base is provided with two second protrusions, both of which are vertically arranged, one on the front side and the other on the rear side of the climbing base. The climbing base is also provided with a second, transversely arranged, internally threaded through-hole. Thus, when installing the climbing base on a window sash, the climbing base is vertically inserted into a groove on the window sash frame, with both second protrusions nestled within the groove. Then, a set screw is inserted through the second internally threaded through-hole and rests against the groove, completing the installation of the climbing base. This results in a simple structure and easy installation.

[0011] In some embodiments of the present invention, the climbing base is provided with a second transverse through-hole. This second through-hole allows for installation of the climbing base by passing a self-tapping screw through the second through-hole and screwing it into the frame of the window sash, resulting in a simple structure and easy installation.

[0012] In some embodiments of the present invention, the climbing assembly further includes an elastic member connected between the climbing base and the support piece. When the window sash is opened, the support piece would otherwise sag under the force of gravity. However, the elastic member enables the support piece to overcome gravity and maintain a downwardly tilted, backward position. This allows the notched corner of the window sash to accurately abut against the abutment portion when the window sash is closed.

[0013] In some embodiments of the present invention, the elastic member is a torsion spring, which is sleeved around the outside of the first hinge shaft, with its ends respectively connected to the climbing seat and the support plate. The torsion spring can be sleeved around the outside of the first hinge shaft without requiring additional fixing structures, resulting in a simple, compact structure and easy assembly.

[0014] In some embodiments of the present invention, the climbing seat is provided with a second limit block, and the support piece is provided with a limit portion. The trajectory of the limit portion's rotation about the first hinge axis is referred to as a first trajectory, and the second limit block is provided on the first trajectory. The support piece has a second state when rotating about the first hinge axis. In the second state, the missing corner is located below and behind the first hinge axis, and the limit portion is in close proximity to the second limit block. The provision of the second limit block and the limit portion prevents the missing corner from moving above the abutment portion when the window sash is closed, thereby preventing the window sash from being lifted.

[0015] In some embodiments of the present invention, the climbing seat is further provided with a first limit block, wherein the first limit block and the second limit block are spaced apart on the first track, and the limit portion is provided between the first limit block and the second limit block. The support piece also has a first state when rotating about the first hinge axis, in which the missing corner is located below the first hinge axis and the limit portion is close to the first limit block. The first limit member can prevent the support piece from rotating too far, thereby preventing the window sash from falling back from its raised position.

[0029] Reference below Figures 1 to 6 A stepless climbing device for doors and windows according to an embodiment of the present invention is described.

[0030] According to an embodiment of the present invention, the stepless climbing device for doors and windows includes a positioning seat and a climbing assembly. The positioning seat is provided with an abutting portion, the abutting portion having a first abutting surface 111 and a second abutting surface 112, with the orientation of the first abutting surface 111 located at the abutting portion as the front side, and the second abutting surface 112 located at the top of the abutting portion; the climbing assembly includes a climbing seat 210 and a supporting plate 230, the top of the supporting plate 230 is hinged to the climbing seat 210, and the hinge axis at the hinge is called the first hinge axis 220, the first hinge axis 220 is arranged horizontally, and the bottom of the supporting plate 230 is provided with a notch 231, the supporting plate 230 has a first edge and a second edge, the first edge is arranged at the front side of the notch 231, and the second edge is arranged at the top of the notch 231, the first edge is adapted to the first abutting surface 111, and the second edge is adapted to the second abutting surface 112.

[0031] For example, Figure 5 and Figure 6 As shown, when in use, the positioning seat can be installed on the window frame 300, with the front side of the positioning seat facing the outdoors, and the first abutting surface 111 facing the outdoors. The positioning seat can be installed on the bottom beam of the window frame 300 or the side beam of the window frame 300 by bolt connection, clamping, pin connection or other suitable methods. The abutting portion on the positioning seat is provided with a first abutting surface 111 facing the front side and a second abutting surface 112 facing the upper side. The first abutting surface 111 and the second abutting surface 112 can be perpendicular to each other; the climbing seat 210 can be installed on the side beam of the window sash 400 by bolt connection, clamping, pin connection or other suitable methods, and the notch 231 is provided on the bottom rear side of the support plate 230, with the first edge extending vertically and the second edge extending front and back; when the window sash 400 is closed, the first edge is close to the first abutting surface 111 and the second edge is close to the second abutting surface 112; the first hinge shaft 220 can be a rivet.

[0032] When the sash 400 is in the open position, the support piece 230 is in the closed position and the first hinge shaft 220 is in the closed position.

[0033] In some embodiments of the present invention, the positioning seat is provided with a mounting portion 120, which is provided at the bottom of the positioning seat, and the abutting portion has two third abutting surfaces 113, which are respectively located on the left and right sides of the abutting portion. The mounting portion 120 is used to connect the positioning seat to the window frame 300, and the third abutting surface 113 can be perpendicular to the first abutting surface 111. In this way, the positioning seat has two installation methods. The positioning seat can be installed on the bottom beam of the window frame 300, or on the left beam or right beam of the window frame 300. Figure 3 When the positioning seat is installed on the bottom beam, the first abutting surface 111 faces forward and the second abutting surface 112 faces upward. When the window sash 400 is closed, the second abutting surface 112 abuts against the second edge. Figure 4 When the positioning seat is installed on the side beam of the window frame 300, the first abutting surface 111 faces forward and the third abutting surface 113 faces upward. At this time, when the window sash 400 is closed, the third abutting surface 113 abuts against the second edge; the positioning seat can be installed in a suitable position according to the needs of the user, and has better versatility.

[0034] In some embodiments of the present invention, the mounting portion 120 is a strip-shaped protrusion, the bottom of the strip-shaped protrusion is provided with a first convex edge 121, the abutting portion is provided with a first internally threaded through hole 130, and the first internally threaded through hole 130 is arranged obliquely; the strip-shaped protrusion is arranged transversely at the front bottom of the abutting portion, the first convex edge 121 protrudes forward from the strip-shaped protrusion, and the first internally threaded through hole 130 faces the rear bottom of the abutting portion; or, the strip-shaped protrusion is arranged transversely at the rear bottom of the abutting portion, the first convex edge 121 protrudes backward from the strip-shaped protrusion, and the first internally threaded through hole 130 faces the front bottom of the abutting portion. Figure 5The outer frames of the door and window frames 300 and the door and window sashes 400 of the aluminum alloy doors and windows have grooves with a "C"-shaped cross-section; the first convex edge 121 is extended horizontally. By setting the first convex edge 121 and the first internally threaded through hole 130, when the positioning seat is installed on the window frame 300, the first convex edge 121 can be embedded in one side of the groove, and then a set screw can be used to pass through the first internally threaded through hole 130 and rest against the other side of the groove, thus completing the installation of the positioning seat. The structure is simple and the installation operation is easy; the mounting portion 120, the strip-shaped protrusion, and the first convex edge 121 can be an integrated component.

[0035] In some embodiments of the present invention, a first through hole 140 is vertically provided on the positioning seat. Figure 1 The number of the first through holes 140 can be two, and the first internally threaded through hole 130 is arranged between the two first through holes 140. The first through hole 140 can be a countersunk hole. By setting the first through hole 140, when installing the positioning seat, a self-tapping screw can be used to pass through the first through hole 140 and then screwed into the window frame 300 to complete the installation of the positioning seat. The structure is simple and the installation operation is easy. The positioning seat can also be pre-fixed with a set screw and then fixed with a self-tapping screw to avoid dislocation caused by direct use of self-tapping screws, which is more convenient for installation.

[0036] In some embodiments of the present invention, the climbing base 210 is provided with two second protrusions 211, both of which are vertically arranged and located on the front and rear sides of the climbing base 210, respectively. A second internally threaded through hole 212 is also provided in the climbing base 210. The second protrusion 211 located on the front side protrudes forward, while the second protrusion 211 located on the rear side protrudes rearward. Thus, when installing the climbing base 210 on the window sash 400, the climbing base 210 can be vertically inserted into a groove on the frame of the window sash 400, so that both second protrusions 211 are embedded in the inner side of the groove. Then, a set screw is inserted through the second internally threaded through hole 212 and abuts against the groove, thus completing the installation of the climbing base 210. This structure is simple and the installation operation is easy. The number of second internally threaded through holes 212 can be two, and the two second internally threaded through holes 212 can be located on the front upper side and the rear upper side of the first hinge shaft 220, respectively.

[0037] In some embodiments of the present invention, a second through hole 213 is provided in a transverse direction on the climbing seat 210. There can be two second through holes 213, with the second internally threaded through hole 212 and the first hinge shaft 220 both disposed between the two second through holes 213. The second through hole 213 can be a countersunk hole. By providing the second through holes 213, when installing the climbing seat 210, self-tapping screws can be passed through the second through holes 213 and screwed into the frame of the window sash 400 to complete the installation of the climbing seat 210. This provides a simple structure and easy installation. Alternatively, the climbing seat 210 can be pre-fixed with set screws before being fixed with self-tapping screws, avoiding misalignment that can occur with direct self-tapping screw fixation, making installation more convenient.

[0038] In some embodiments of the present invention, the climbing assembly further includes an elastic member 240 connected between the climbing seat 210 and the support piece 230. When the window sash 400 is opened, the support piece 230 would otherwise sag under the action of gravity. However, by providing the elastic member 240, the elastic member 240 enables the support piece 230 to overcome gravity and maintain a tilted position from top to bottom. This allows the notched corner 231 to accurately abut against the abutment portion when the window sash 400 is closed. The elastic member 240 can be a spring, a spring, or other suitable component.

[0039] In some embodiments of the present invention, the elastic member 240 is a torsion spring, which is sleeved on the outside of the first hinge shaft 220, and the two ends of the torsion spring are respectively connected to the climbing seat 210 and the support plate 230. Figure 2 When assembling the climbing assembly, the torsion spring can be placed on the climbing seat 210 first, and then the support piece 230 can be placed so that the torsion spring is clamped between the support piece 230 and the climbing seat 210, and then the support piece 230 and the climbing seat 210 can be riveted into a whole with rivets; the torsion spring can be sleeved on the outside of the first hinge shaft 220, and there is no need to set up an additional fixing structure to fix it. The structure is simple and compact, and the assembly is easy.

[0040] In some embodiments of the present invention, a second limiting block 214 is provided on the climbing seat 210, and a limiting portion 232 is provided on the support plate 230. The trajectory of the limiting portion 232 rotating around the first hinge shaft 220 is called the first trajectory, and the second limiting block 214 is provided on the first trajectory; the support plate 230 rotates around the first hinge shaft 220 to have a second state. In the second state, the missing corner 231 is located at the rear lower part of the first hinge shaft 220, and the limiting portion 232 is close to the second limiting block 214. The limiting portion 232 can be provided on the upper side of the first hinge shaft 220, and the second limiting block 214 is provided on the front upper side of the hinge shaft, with reference to FIG. Figure 5When the window sash 400 is opened, the missing corner 231 of the support piece 230 has a tendency to rise upward and rearward under the action of the elastic member 240, causing the support piece 230 to tilt backward from top to bottom. When the support piece 230 is in the second state, the limiting portion 232 abuts against the second limiting block 214, preventing the missing corner 231 from continuing to rise, so that the missing corner 231 is aligned with the abutting portion; by providing the second limiting block 214 and the limiting portion 232, it is prevented that the missing corner 231 moves above the abutting portion when the window sash 400 is closed, resulting in the inability to lift the window sash 400.

[0041] In some embodiments of the present invention, a first limiting block 215 is further provided on the climbing seat 210. The first limiting block 215 and the second limiting block 214 are spaced apart on the first track, and the limiting portion 232 is provided between the first limiting block 215 and the second limiting block 214. The support piece 230 rotates around the first hinge shaft 220 and also has a first state. In the first state, the missing corner 231 is located below the first hinge shaft 220, and the limiting portion 232 is close to the first limiting block 215. The climbing seat 210, the two second protrusions 211, the first limiting block 215, and the second limiting block 214 can be an integral component, and the limiting portion 232 and the support piece 230 can be an integral component. The first limiting block 215 is provided on the upper rear side of the hinge shaft, with reference to FIG. Figure 6 When the window sash 400 is closed, the support piece 230 is upright and the support piece 230 is in the first state. The first limit member can prevent the support piece 230 from rotating too much and prevent the window sash 400 from falling back from the raised position.
