Description
Technical Field
The invention relates to the technical field of window hardware, in particular to a sliding support structure.
Background
The sliding support is an important part in door and window hardware and used for connecting a window sash with a window frame, so that the window can be opened and closed, two conventional installation modes are adopted, one is to install the sliding support on the upper side and the lower side of the window sash, namely a side opening window structure can be formed, and the other is to install the sliding support on the left side and the right side of the window sash, namely an upper suspension window structure can be formed. The construction is equally suitable for the installation of door leaves.
When the sliding support is used for installing the window sashes, a common installation mode is that a hinge (a hinge) is not installed, so that a certain gap is opened at one side of the hinge after the window sashes are opened, ventilation is enhanced, and cleaning of outdoor side surfaces of the window is facilitated. However, in the window sash opening mode, the sliding support is required to drive the window sash to do composite movement of inward, outward and translational movement so as to avoid the interference of the movement of the window sash and the window frame, so that the existing sliding support has more hinge points and connecting rods, and the structure is more complex; in addition, the sliding of the sliding support is translational, when each connecting rod is in a straight line, the window sashes are closed, and the window sashes lack pressing force towards the inner side (closing direction), so that the air tightness of the window sashes is poor, and the effects of sound insulation, heat insulation, rain protection and the like are affected.

In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
the sliding support structure comprises a transverse mounting bar for fixing along a window frame, a short cantilever positioned at the left side and used for connecting the mounting bar with a window sash, and a long cantilever positioned at the right side and used for respectively connecting the window frame with the window sash through a first hinge point and a second hinge point; the mounting strip is provided with a sliding groove extending along the length direction of the mounting strip, the right section part of the short cantilever is provided with a left pin shaft and a right pin shaft which are assembled in the sliding groove in a sliding way, the left section part is provided with a third hinge point used for being hinged with a window sash, the left end of the sliding groove is provided with an offset section, and in the window sash closing process, the offset section forces the left pin shaft to move towards the inner side of the window sash and/or the right pin shaft to move towards the outer side of the window sash, so that the third hinge point is driven to deflect towards the inner side of the window sash.
Preferably, the offset section of the sliding chute is a straight line section inclined towards the inner side of the window sash.
Preferably, the pin shaft is rotatably mounted on the short cantilever, the pin shaft on the right side is provided with a columnar section with the same width as the chute, and the columnar section is provided with two matching planes which are in contact with the inner wall of the chute.
Preferably, the third hinge point is located at the left end of the short cantilever, and the two pins are located at the middle and right ends of the short cantilever, respectively.
Preferably, the short cantilever is in a long block shape, the pin shaft on the right side is arranged on the short cantilever at a position close to a long central line, the pin shaft on the left side is arranged on one side of the short cantilever, which is close to the inner side, and the third hinge point is arranged on one side of the short cantilever, which is close to the outer side.
In a preferred scheme, the angles of the left end and the right end of the short cantilever close to the inner side are chamfer angles of avoidance.
Preferably, the long cantilever is hinged to the right end of the mounting bar through the first hinge point, and the long cantilever and the mounting bar are hinged to each other through an eccentric nail.

Detailed Description
The invention is further described below with reference to the accompanying drawings:
the terms about directions, such as left, right, inner, outer and the like, in the application are merely used for convenience in describing the structure, wherein the left side is one side of a window sash mounting hinge (hinge), and the right side is opposite; the inner side is the side of the window in the closing direction of the window sash, for example, the indoor side of the outward opening window is the inner side, and the outer side is the opposite side.
Referring to fig. 1 and 2, a sliding support structure includes a mounting bar 1 for fixing along a window frame, a short cantilever 2 on the left side for connecting the mounting bar 1 with a window sash, and a long cantilever 3 on the right side for connecting the window frame with the window sash through a first hinge point 7 and a second hinge point 8, respectively; when the sliding support is installed, the installation strip 1 is fixed on the inner side edge of the window frame, and the short cantilever 2 and the long cantilever 3 are used for connecting and supporting the window sashes. The mounting strip 1 is provided with a sliding groove 4 extending along the length direction, the right section part of the short cantilever 2 is provided with a left hinge pin 5 and a right hinge pin 5 which are assembled in the sliding groove 4 in a sliding way, the left section part is provided with a third hinge point 6 for hinging with a window sash, the left end of the sliding groove 4 is provided with an offset section 41, and during the window sash closing process, the offset section 41 forces the left hinge pin 5 to move towards the inner side of the window sash and/or the right hinge pin 5 to move towards the outer side of the window sash, so as to drive the third hinge point 6 to deflect towards the inner side of the window sash. The offset section 41 may have various forms, such as an offset slot extending from the left end of the chute 4 to the inner side of the window sash, so that the left pin 5 slides into the offset slot and then is offset to the inner side; or a deviation groove which diverges towards the outer side of the window sash is formed near the left end of the sliding groove 4, so that the pin shaft 5 on the right side slides into the deviation groove and then deviates towards the outer side; or an offset groove is formed from the left end of the chute 4 to the inner side and the outer side of the window sash respectively, so that the pin shaft 5 on the left side slides inwards along the inner side offset groove and the pin shaft 5 on the right side slides outwards along the outer side offset groove. When the pin 5 slides along the offset section 41, the third hinge point 6 rotates about one of the pins 5. The offset groove shape of the offset section 41 may be a slope, an arc, a gradually excessive step, or the like.
After the sliding support structure is arranged between a window frame and a window sash, in the opening and closing process of the window sash, a long cantilever 3 hinged between the window frame and the window sash drives a short cantilever 2 to move through the window sash, so that two pin shafts 5 of the short cantilever 2 slide along a sliding chute 4 of an installation strip 1, and after the pin shafts 5 of the short cantilever 2 slide into an offset section 41, a dynamic lever structure is formed by a third hinge point 6 of the short cantilever 2 and the two pin shafts 5.
In the window sash closing process, the pin shaft 5 on the short cantilever 2 gradually slides into the offset section 41 by translation, the offset section 41 forces the left pin shaft 5 to move towards the inner side of the window sash and/or the right pin shaft 5 to move towards the outer side of the window sash, the window sash can be driven to deflect towards the inner side of the window sash along with the third hinge point 6, and the limiting of the side wall of the offset section 41 is matched to generate an inward pressing force, so that the window sash has good air tightness; the window sash is deflected towards the outer side of the window sash along with the third hinge point 6 and then horizontally slides, so that the edge of the window sash is far away from the window frame towards the outer side, and interference between the window sash opening process and the window frame is avoided. The sliding support structure only needs two cantilevers and a small number of hinge points, and compared with the existing similar sliding support structure, the structure is greatly simplified.
Referring to fig. 3, the sliding support structure is shown in fig. 3 in two states, when the window sash is closed and when the window sash is fully opened, and the third hinge point 6 follows the movement track a of the window sash. In one embodiment, the offset section 41 of the chute 4 is a straight section inclined toward the inside of the window sash. During the closing process of the window sash, the pin shaft 5 at the left side slides into the offset section 41, so that the window sash can be offset towards the inner side along with the third hinge point 6; during the opening of the window sash, the left pin 5 slides out of the offset section 41, so that the window sash is offset outwards along with the third hinge point 6. The chute 4 is simple in structure and enables the opening and closing processes of the window sashes to be smoother.
Referring to fig. 4, in one embodiment, the pin 5 is rotatably mounted on the short cantilever 2, the pin 5 on the right side has a cylindrical section with the same width as the chute 4, and the cylindrical section has two mating planes 51 contacting the inner wall of the chute 4. The rotation mounting mode of the pin shaft 5 can be that the pin shaft 5 rotates around the shaft relative to the short cantilever 2, or the pin shaft 5 is fixed, and a rotation sleeve 501 which can rotate relatively is sleeved outside the pin shaft 5; the pin 5 in this embodiment is a structure that a fixed pin 5 is sleeved with a rotating sleeve 501. The pin 5 on the right side is provided with two matching planes 51 which are matched with the chute 4 in an equal width manner, and as the pin 5 on the right side does not need to slide into the offset section 41 and the pin 5 bears larger force of a window sash, the two matching planes 51 enable the pin 5 to have larger contact area with the side wall of the chute 4, so that the reliability of the sliding support and the stability during sliding can be improved.
In one embodiment, the third hinge point 6 is located at the left end of the short cantilever 2, and the two pins 5 are located at the middle and right ends of the short cantilever 2, respectively. A certain distance is reserved between the third hinge point 6 and the pin shaft 5 on the left side, when the short cantilever 2 swings around the pin shaft 5 in a rotating way, the window sash can swing along with the short cantilever 2 in a rotating way to a larger extent, even if the offset distance of the offset section 41 along the width direction of the installation strip 1 is short, the window sash can also generate a larger outward offset distance along with the third hinge point 6 through the short cantilever 2 in the window sash opening process, so that the window sash is prevented from interfering with a window frame, and the installation strip 1 can be narrower; and the third hinge point 6 and the pin shafts 5 at the left side and the right side are dispersed on the short cantilever 2, so that the stress at the three points is more uniform, and the loss caused by uneven stress can be reduced.
In one embodiment, the short cantilever 2 is in a long block shape, the pin 5 on the right side is disposed on the short cantilever 2 at a position close to a long center line (center line along the long side direction), the pin 5 on the left side is disposed on the inner side of the short cantilever 2, and the third hinge point 6 is disposed on the outer side of the short cantilever 2. When the window sash is closed, the width of the short cantilever 2 needs to be basically aligned with the mounting strip 1, and in the limited width space of the short cantilever, the third hinge point 6 and the distribution position of the two pin shafts 5 can enable the lever distance between three points on the short cantilever 2 to be longer, the space of the short cantilever 2 in the width direction is fully utilized, and the width of the short cantilever 2 and the mounting strip 1 can be further narrowed.
In one embodiment, the left and right inner corners of the short cantilever 2 are rounded corners 21. After the chamfer 21 is arranged, the short cantilever 2 and the window frame can be prevented from interfering in the opening and closing process of the window sash, so that the offset section 41 does not need to be provided with a larger offset distance, and the widths of the short cantilever 2 and the mounting strip 1 are further reduced.
In one embodiment, the long cantilever 3 is hinged to the right side of the mounting bar 1 through the first hinge point 7, and the long cantilever 3 and the mounting bar 1 are hinged to each other through an eccentric pin 31. The long cantilever 3 is hinged on the mounting strip 1, so that the sliding support is integrated, and the long cantilever 3 is convenient for the connection and the mounting of the long cantilever and the mounting strip in the early stage; the long cantilever 3 is hinged through the eccentric nail 31, so that the movement track of the long cantilever 3 can be improved to a certain extent, and the sliding support drives the window sash to be opened and closed more smoothly.
In one embodiment, a fixing pin 61 is vertically fixed on the third hinge point 6 of the short cantilever 2, a fixing block 62 for fixing with a window sash is rotatably sleeved on the fixing pin 61, and an adjusting screw 63 for axially adjusting the relative position of the fixing pin 61 and the fixing block 62 is further provided on the fixing block 62 corresponding to the axial top end of the fixing pin 61. By rotating the adjusting screw 63, the position of the window sash can be adjusted along the axial direction 5 of the fixing pin 61, and the window sash can be conveniently installed and adjusted.
One embodiment further comprises a fixing bar 9 for fixing to the sash, one end of the fixing bar 9 being hinged to the short cantilever 2 at the third hinge point 6 and the other end being hinged to the long cantilever 3 at the second hinge point 8. The two ends of the fixing strip 9 can be respectively hinged with the long cantilever 3 and the short cantilever 2, so that the sliding support forms a whole, and the installation and the fixation between the subsequent sliding support and the window sash can be simplified.
In one embodiment, a base plate 11 is fixed to the bottom surface of the mounting bar 1, and a groove 111 having a width larger than that of the sliding groove 4 is provided on the top surface of the base plate 11 along the sliding groove 4. Because the pin shaft 5 is provided with the T-shaped head part for preventing the pin shaft from being separated from the sliding groove 4, the base plate 11 is used for heightening the fixing strip 9 to provide a sliding space for the sliding groove 4, so that the integral strength can be ensured, and the processing of the sliding groove 4 and the installation of a sliding support can be facilitated.
The above description should not be taken as limiting the scope of the invention, and any modifications, equivalent variations and modifications made to the above embodiments according to the technical principles of the present invention still fall within the scope of the technical solutions of the present invention.
