Description

[Technical field]

[0001] The invention relates to a heavy-duty sliding support hinge for an outward-opening window. [Background technology]

[0002] The sliding support hinge structure of the outward-opening window currently on the market, as shown in the application document of announcement number CN103485623A, is generally a four-link structure consisting of a short rod, a middle rod, a long rod, a support arm and a slider installed on a slide slot, wherein one end of the short rod and the middle rod are rotatably connected to the left and right ends of the slider respectively, the other end of the short rod is rotatably connected to one end of the support arm, the other end of the middle rod is rotatably connected to the middle part of the long rod, one end of the long rod is rotatably connected to the slide slot, and the other end is rotatably connected to the middle part of the support arm, the slider is slidably connected to the slide slot, and the support arm is used to install the window sash, wherein the slide slot is provided with a wrap angle, and one end of the support arm is provided with a guide head that can cooperate with the wrap angle to make the pentagon composed of the short rod, the middle rod, the long rod, the support arm and a slider close and close. The force of the sliding support hinge of this structure is mainly distributed on the short rod, which is suspended in the air and only supported by the hinge point connected to the slider (such as rotating connection through rivets) and a small part supported above the slider. The support area is small, the cantilever is long, the stress is too concentrated, the short rod and the rivet connected to the slider are easy to wear, and the service life is short. In particular, the performance of window sashes is becoming more and more advanced and multifunctional, and their weight is also getting heavier. The sliding support hinge of the existing structure is increasingly unable to meet the market demand.

[0003] The present invention is made based on this situation. [Summary of the invention]

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a heavy-duty outward-opening window sliding support hinge with simple structure, good structural strength, reasonable force distribution and long service life.

The short rod 2, the middle rod 3, the long rod 4 and the support arm 5 form a parallelogram 10 that changes continuously as the sliding support hinge is opened and closed between the nodes where the two adjacent rotational connections are made.

[0007] The heavy-duty sliding support hinge for outward-opening windows as described above is characterized in that a clearance groove 31 is provided on the middle rod 3 for avoiding the rotation connection point between the short rod 2 and the first sliding block 6 when closing.

[0008] A heavy-duty outward-opening window sliding support hinge as described above is characterized in that: the slide groove 1 includes an L-shaped plate 13 composed of a vertical plate 11 and a horizontal plate 12, the upper end of the vertical plate 11 of the L-shaped plate 13 is provided with an inverted U-shaped slide rail 14 facing the horizontal plate 12, the first slider 6 and the second slider 7 are placed on the horizontal plate 12, the first slider 6 and the second slider 7 are provided with a slide table 61 inserted into the slide rail 14 and slidingly matched with the slide rail 14, and a sliding opening 15 is provided between the horizontal plate 12 and the slide rail 14 for the first slider 6 and the second slider 7 to slide and limit the first slider 6 and the second slider 7 between the horizontal plate 12 and the slide rail 14.

[0009] A heavy-duty outward-opening window sliding support hinge as described above is characterized in that: a locking plate 8 is provided below the slide slot 1, which can be stuck in the groove 101 of the aluminum profile of the window frame 100 when rotating, and the locking plate 8 is connected to the slide slot 1 through a hexagon socket screw 81. The locking plate 8 follows the rotation of the hexagon socket screw 81, and the slide slot 1 is provided with a screw hole 16 for locking the slide slot 1 on the window frame 100.

[0010] A heavy-duty outward-opening window sliding support hinge as described above is characterized in that a reinforcing plate 9 for supporting the long rod 4 is fixed on the slide groove 1 at the connection between the long rod 4 and the slide groove 1, and the reinforcing plate 9 is located between the long rod 4 and the slide groove 1 and is rotatably connected to the long rod 4.

[0011] A heavy-duty outward-opening window sliding support hinge as described above is characterized in that: the reinforcing plate 9 is provided with a positioning support plate 91 extending from one end of the slide groove 1 below the bottom of the slide groove 1, and the positioning support plate 91 is used to extend into the groove 101 of the window frame 100 and be supported on the bottom of the groove 101, and cooperate with the left and right sides of the groove 101 to position the left and right positions of the slide groove 1 on the groove 101.

[0012] A heavy-duty outward-opening window sliding support hinge as described above is characterized in that: a convex bump 92 is stamped from the bottom to the top on the reinforcing plate 9, a supporting boss 17 is provided on the slide groove 1 and supported on the bottom of the convex bump 92, and the long rod 4 is rotatably connected to the convex bump 92 and the supporting boss 17 simultaneously through a rivet.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. In the present invention, the short rod 2, the middle rod 3, the long rod 4 and the supporting arm 5 form a parallelogram 10 that changes continuously as the sliding support hinge is opened and closed between the nodes where the two adjacent rods are connected in rotation. The short rod 2 and the middle rod 3 are connected in rotation after being crossed by the double slider structure of the first slider 6 and the second slider 7, so that a triangle with unchanged waists and variable length and shortened bottom sides is formed between the connection nodes of the short rod 2 and the first slider 6, the connection nodes of the middle rod 3 and the second slider 7, and the connection nodes of the short rod 2 and the middle rod 3. The parallelogram 10 is used to realize the heavy-duty outward-opening window sliding support hinge. The window sash is opened and closed, thereby realizing the opening and closing of the window sash. The new connecting rod connection structure is adopted. Since the short rod 2 and the middle rod 3 are cross-connected, and the middle rod 3 supports the short rod 2 from the middle, the length of the arm suspended between the force point and the support point is shortened, and the torsion of the short rod 2 acted on the window sash is relatively reduced. At the same time, the short rod 2 has two connection points and support points, the middle rod 3 and the first slider 6, which disperses the force of the rotating connection structure. For example, when the rivet is used for the rotation connection, the service life of the rivet is increased. Another method can also avoid the use of the wrap angle and the guide head structure, and simplify the structure of the slide 1 and the bracket arm 5.

[0015] 2. The slide 1 in the present invention is formed by an L-shaped plate 13 and an inverted U-shaped slide rail 14. When the first slider 6 and the second slider 7 are connected, it is only necessary to place the first slider 6 and the second slider 7 relative to the horizontal plate 12, and insert the slide 61 corresponding to the slide rail 14 from one end of the slide 1. The connection is convenient and fast. At the same time, the inverted U-shaped slide rail 14 can prevent dust and garbage from accumulating. When the L-shaped plate 13 accumulates dust and other garbage, it is only necessary to sweep the garbage horizontally along the horizontal plate 12, which is convenient to clean and solves the problem of difficulty in cleaning garbage caused by the traditional concave structure slide.

[0016] 3. In the present invention, the slide 1 is used to raise the long rod 4 by fixing the reinforcing sheet 9, and the long rod 4 is connected by the slide 1 and the reinforcing sheet 9, so as to avoid directly raising the long rod 4 by punching and stretching the corresponding structure on the slide 1. Due to the punched and stretched structure, the higher the stretching boss is, the weaker the structural strength is. The reinforcing sheet 9 is used to raise the long rod 4 to a corresponding height, thereby strengthening the structural strength of the connection between the long rod 4 and the slide 1. The long rod 4 is connected by the slide 1 and the reinforcing sheet 9, and the force is shared, and the connection strength is good, which meets the increasing weight requirements of the window sash due to the performance upgrade. Furthermore, the reinforcing sheet 9 is provided with a positioning support sheet 91 extending from one end of the slide 1 below the bottom of the slide 1. The positioning support sheet 91 is used to extend into the channel 101 of the window frame 100 and support the bottom of the channel 101 of the window frame 100, forming an intermediate support to prevent the slide 1 and the reinforcing sheet 9 from collapsing and deforming.

[0024] The present invention will be further described below in conjunction with the accompanying drawings:

[0025] like Figures 1 to 6A heavy-duty outward-opening window sliding support hinge shown in the figure comprises a slide 1, a short rod 2, a middle rod 3, a long rod 4 and a bracket 5, one end of the long rod 4 is rotatably connected to the slide 1, and the other end is rotatably connected to the middle of the bracket 5, and one side of the slide 1 located at the connection point between the long rod 4 and the slide 1 is slidably connected to two first sliders 6 and second sliders 7 that can slide independently, wherein the first slider 6 is located between the second slider 7 and the connection point between the long rod 4 and the slide 1, one end of the short rod 2 is rotatably connected to the first slider 6, and the other end is rotatably connected to the bracket 5 One end is rotationally connected, one end of the middle rod 3 is rotationally connected to the second slider 7, and the other end is rotationally connected to the long rod 4, and the rotation connection point is located between the rotation connection point of the long rod and the slide slot 1 and the rotation connection point of the long rod and the support arm 5, the middle rod 3 crosses the short rod 2 and the middle rod is supported at the bottom of the short rod 2, the middle rod 3 and the short rod 2 are rotationally connected at the intersection, and the short rod 2, the middle rod 3, the long rod 4 and the support arm 5 form a parallelogram 10 between the nodes where the two adjacent rotational connections are made, which changes continuously as the sliding support hinge is opened and closed.

[0026] The rotational connection between the above-mentioned different components is achieved by hinged connection through rivets.

[0027] The double slider structure of the first slider 6 and the second slider 7 is coordinated to make the short rod 2 and the middle rod 3 cross and then rotate and connect, so that a triangle with two unchanged waists and variable bottom sides is formed between the connection nodes of the short rod 2 and the first slider 6, the connection nodes of the middle rod 3 and the second slider 7, and the connection nodes of the short rod 2 and the middle rod 3. The opening and closing of the heavy-duty outward-opening window sliding support hinge is realized in cooperation with the parallelogram 10, thereby realizing the opening and closing of the window sash. The new connecting rod connection structure is adopted. Since the short rod 2 and the middle rod 3 are cross-connected, and the middle rod 3 supports the short rod 2 from the middle, the length of the arm suspended between the force point and the support point is shortened, and the torsion of the short rod 2 acted on the window sash is relatively reduced. At the same time, the short rod 2 has two connection points and support points, namely the middle rod 3 and the first slider 6, so as to disperse the force of the rotating connection structure. For example, when the rivet is used for rotation connection, the service life of the rivet is increased; another method can also avoid the use of the wrap angle and guide head structure, and simplify the structure of the slide groove 1 and the support arm 5.

[0028] The middle rod 3 is provided with a clearance groove 31 for avoiding the rotation connection point of the short rod 2 and the first slider 6 when closing, so that the sliding track of the rotation connection point of the short rod 2 and the first slider 6 and the rotation connection point of the middle rod 3 and the second slider 7 overlap, so that after closing, the slide groove 1, the short rod 2, the middle rod 3, the long rod 4 and the supporting arm 5 are parallel and overlapped to form a straight line. Figure 4 The window sash has good closing performance and reduces the volume of the heavy-duty outward-opening window after the sliding support hinge is closed.

[0029] like Figure 3The slide 1 includes an L-shaped plate 13 composed of a vertical plate 11 and a horizontal plate 12. The upper end of the vertical plate 11 of the L-shaped plate 13 is provided with an inverted U-shaped slide rail 14 facing the horizontal plate 12. The first slider 6 and the second slider 7 are placed on the horizontal plate 12. The first slider 6 and the second slider 7 are provided with a slide table 61 inserted into the slide rail 14 and slidingly matched with the slide rail 14. A sliding opening 15 is provided between the horizontal plate 12 and the slide rail 14 for the first slider 6 and the second slider 7 to slide and limit the first slider 6 and the second slider 7 between the horizontal plate 12 and the slide rail 14. The connection structure between the slide 1 and the first slider 6 and the second slider 7 is simple. It only needs to place the first slider 6 and the second slider 7 relative to the horizontal plate 12, and insert the slide 61 corresponding to the slide rail 14 from one end of the slide 1. The connection is convenient and fast. At the same time, the inverted U-shaped slide rail 14 can prevent dust and garbage from accumulating. When dust and other garbage are deposited on the L-shaped plate 13, it only needs to sweep the garbage horizontally along the horizontal plate 12, which is convenient to clean and solves the problem of difficulty in cleaning garbage caused by the traditional concave structure slide.

[0030] A locking piece 8 is provided below the slide 1, which can be stuck in the channel 101 of the aluminum profile of the window frame 100 when rotating. The locking piece 8 is connected to the slide 1 by a hexagon socket screw 81. The locking piece 8 follows the rotation of the hexagon socket screw 81. The slide 1 is provided with a screw hole 16 for locking the slide 1 on the window frame 100. Since the window frame is usually made of aluminum profile and has the channel 101, when the heavy-duty outward-opening window sliding support hinge is installed on the window frame, it is only necessary to rotate the hexagon socket screw 81 to make the locking piece 8 rotate and get stuck in the channel 101, so that the heavy-duty outward-opening window sliding support hinge can be locked on the window frame, and then the screw is inserted from the screw hole 16 to connect with the window frame, and the heavy-duty outward-opening window sliding support hinge is locked and fixed in the set position. The assembly and disassembly is quick and convenient, and the problem of the traditional complex installation structure with multiple screw holes and multiple screws for locking is solved.

[0031] A reinforcing sheet 9 for supporting the long rod 4 is fixed on the slide slot 1 at the connection between the long rod 4 and the slide slot 1. The reinforcing sheet 9 is located between the long rod 4 and the slide slot 1 and is rotatably connected to the long rod 4 to avoid stamping and stretching the corresponding structure on the slide slot 1 to directly raise the long rod 4. Due to the stamped and stretched structure, the higher the stretching boss is, the weaker the structural strength is. The long rod 4 is padded to a corresponding height by the reinforcing sheet 9, thereby strengthening the structural strength of the connection between the long rod 4 and the slide slot 1. The long rod 4 is connected together by the slide slot 1 and the reinforcing sheet 9, and they are jointly subjected to force, so the connection strength is good, which meets the increasing weight requirements of the window sash due to the performance upgrade.

[0032] Furthermore, if Figure 6When the chute 1 is installed in the channel 101, the chute 1 is usually supported from the left and right sides of the chute 1. The channel 101 avoids the middle area of ​​the bottom of the chute 1 to allow for the structure protruding from the bottom of the chute 1 such as screws or rivets. The connection point between the long rod 4 and the chute 1 is in the middle area of ​​the chute 1 suspended in the air. The structural strength of the middle area of ​​the chute 1 suspended in the air is relatively weak. Under the long-term pressure of the heavy exterior window, the chute 1 and the reinforcing sheet 9 are prone to collapse and deformation, and accelerate the rotation wear of the long rod 4 at the connection. For this reason, the reinforcing sheet 9 is provided with a plurality of reinforcing sheets. A positioning support piece 91 is provided which extends from one end of the slide groove 1 below the bottom of the slide groove 1. The positioning support piece 91 is used to extend into the groove 101 of the window frame 100 and support the bottom of the groove 101 of the window frame 100 to form an intermediate support to prevent the slide groove 1 and the reinforcement piece 9 from sagging and deforming. The width of the positioning support piece 91 corresponds to the width of the groove opening. When the positioning support piece 91 is inserted into the groove 101 from the groove opening, the positioning support piece 91 cooperates with the left and right sides of the groove 101 to position the left and right positions of the slide groove 1 on the groove 101.

[0033] like Figure 1 The reinforcing sheet 9 is stamped with a convex hump 92 from the bottom to the top, and the slide 1 is provided with a support boss 17 that is raised and supported at the bottom of the convex hump 92. The long rod 4 is connected to the convex hump 92 and the support boss 17 by a rivet. Since the reinforcing sheet 9 is padded to a certain height, the convex hump 92 and the support boss 17 only need to be stretched to a very small height, and the structural strength is good. The double structure of the convex hump 92 and the support boss 17 is hinged with the long rod 4 by rivets, and the connection strength is good, the contact area of ​​the rivet rotating surface is increased, and the life of the rivet at the connection is improved. The long rod 4 is padded by the convex hump 92 and separated from the top surface of the reinforcing sheet 9, so as to prevent the long rod 4 from interfering with the reinforcing sheet 9 during rotation and affecting the rotation; and there is a certain gap between the long rod 4 and the top surface of the reinforcing sheet 9, so that the long rod 4 is allowed to have a certain amount of deformation without affecting the normal use of the sliding support hinge.

[0034] The heavy-duty outward-opening window sliding support hinge has a simple structure and good structural strength, can be applied to heavy-duty outward-opening windows, has good safety performance in use, and is easy to install.
