Description

Technical Field

[0001] The invention relates to a window stay, in particular to a window stay installation structure for an anti-falling window. Background Art

[0002] The window stay, also called a sliding stay or hinge, is a common casement window accessory installed between the frame material and the sash material to support the sash and realize the opening and closing function of the sash. The window stay has a bottom groove (also called a sliding groove) assembled with the frame material and a D arm (also called a support arm) assembled with the sash material.

[0003] The installation structure of traditional window supports is installed using self-tapping screws, that is, the bottom groove is assembled with the frame material, and the D arm is assembled with the fan material. As the aluminum alloy profile becomes thinner and thinner, the bonding area between the self-tapping screws and the frame material and the fan material becomes smaller and smaller, usually only 1 to 2 pitches, which makes the reliability of this assembly structure worse. Moreover, in actual use, for example, when installing the air conditioner main unit outdoors, it is necessary to remove the opening fan and then install it back, which will make the bonding strength of the self-tapping screws with the frame material and the fan material worse. Affected by these factors, as well as with the increase in usage time and the increase in the number of openings and closings, the self-tapping screws are easy to fall off, causing window falling accidents.

[0004] In order to solve the problem of falling windows, people have made improvements to the installation structure of window supports, adding anti-falling grooves on the frame material and the fan material, embedding the bottom groove and the D arm of the window support in the corresponding anti-falling grooves, and fixing them by fastening screws. When the fastening screws fall off, the anti-falling grooves can prevent the bottom groove and the D arm from escaping from the frame material and the fan material, thereby achieving the purpose of preventing the window from falling. However, this type of assembly structure still has the following defects: 1. It is inconvenient to assemble. In order to achieve interlocking and prevent the bottom groove and the D arm from escaping from the frame material and the fan material, the edge of the mouth of the anti-falling groove needs to be bent inward to form a blocking part, and the side of the bottom groove and the D arm of the window support needs to extend outward to form a protrusion that cooperates with the blocking part. At the same time, a notch needs to be reserved in the blocking part. During installation, the protrusion needs to be aligned with the notch, and the protrusion is inserted into the anti-falling groove through the notch, and then the window support is moved to make the protrusion away from the notch and cooperate with the blocking part to produce a blocking effect. Moreover, the window stay installed at the upper end of the opening sash and the window stay installed at the lower end of the opening sash must be aligned at the same time, which makes installation more difficult. 2. There is still a certain risk of window falling. When the fastening screw falls off, if the window stay slides in the anti-falling groove and slides to the position where the protrusion and the notch coincide, the window stay can fall out of the anti-falling groove, and there is a risk of window falling. Summary of the invention

[0005] The object of the present invention is to provide a window stay installation structure and a window stay for an anti-falling window, so as to solve the above-mentioned defects existing in the window stay for an anti-falling window.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A falling-proof window support installation structure, comprising:

[0008] An anti-falling groove on the frame material, wherein two opposite edges of the mouth of the anti-falling groove are respectively bent inward to form a first blocking portion and a second blocking portion;

[0009] A bottom groove of the window stay, the bottom groove comprising a main plate body, a side plate body bent downward from one side of the main plate body, and a protrusion bent outward from the bottom end of the side plate body, the protrusion being placed in the anti-fall groove; and

[0010] An insert, the insert is embedded between the first blocking portion of the anti-falling groove, the main plate body and the side plate body of the window support bottom groove, forms a blocking fit with the first blocking portion, and presses the window support bottom groove so that the protrusion forms a blocking fit with the second blocking portion;

[0011] The bottom groove and the insert, the bottom groove and the frame material are respectively locked by screws.

[0012] The installation method is as follows: tilt the window support slightly so that the protrusion on the bottom groove enters the anti-fall groove, put the insert into the anti-fall groove, push it under the main board of the bottom groove, and then use fastening screws to lock the bottom groove and the insert, the bottom groove and the frame material respectively.

[0013] In the above-mentioned anti-fall window support installation structure, preferably, a gap is left between the insert and the side plate of the window support bottom groove, or between the insert and the side of the anti-fall groove, so that the window support can slide in the anti-fall groove after the locking screw between the window support bottom groove and the frame material falls off, thereby producing an early warning effect.

[0014] In the above-mentioned anti-fall window support installation structure, preferably, the inlay adopts a strip structure.

[0015] In the above-mentioned anti-falling window stay installation structure, preferably, the insert has a plurality of through holes for combining the window stay bottom groove and the frame material, and a plurality of threaded holes for combining the window stay bottom groove and the insert.

[0016] A window stay, comprising a bottom groove for assembling with a frame material, and a D arm for assembling with a sash material, wherein: the bottom groove includes a main plate body, a side plate body formed by bending downward from one edge of the main plate body, and a protrusion formed by bending outward from the bottom end of the side plate body; the window stay also includes an inlay, which is used to be embedded in an anti-fall groove, between the main plate body and the side plate body of the window stay bottom groove, to form a blocking fit with a blocking part at one edge of the anti-fall groove, and to squeeze the window stay bottom groove so that the protrusion forms a blocking fit with the blocking part at the other edge of the anti-fall groove.

[0017] In the above-mentioned window stay, preferably, the inlay adopts a strip structure.

[0018] In the above-mentioned window stay, preferably, the insert has a plurality of through holes for combining the bottom groove of the window stay and the frame material, and a plurality of threaded holes for combining the bottom groove of the window stay and the insert.

[0019] In the above-mentioned window stay, preferably, the size of the insert satisfies: after assembly, a gap is formed between the insert and the side plate of the window stay bottom groove, or between the insert and the side of the anti-fall groove, so that the window stay can slide in the anti-fall groove after the locking screw between the window stay bottom groove and the frame material falls off, thereby producing a warning effect.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] Easy installation. There is no need to reserve a gap in the blocking part of the anti-falling groove, and there is no need to align the gap and the protrusion during installation. Just tilt the window support slightly so that the protrusion on the bottom groove enters the anti-falling groove, put the insert into the anti-falling groove, push it under the main body of the bottom groove, and then use the fastening screws to lock the bottom groove and the insert, the bottom groove and the frame material respectively. The installation is very convenient.

[0022] The anti-falling window has a good effect. The window stay can slide arbitrarily in the anti-falling groove without falling out of the anti-falling groove. Therefore, even if the fastening screws between the bottom groove and the frame material fall off, there will be no hidden danger of falling windows. Unless the fastening screws between the bottom groove and the inlay also fall off, and the inlay and the bottom groove are disengaged, but only when the fastening screws between the bottom groove and the frame material fall off, the fastening screws between the bottom groove and the inlay will be stressed, and at this time the window stay will slide in the anti-falling groove. This sliding will cause the open window to be unable to be completely closed. This phenomenon is easy to be discovered by the user in time, achieving the effect of early warning. After the user discovers the early warning, he will repair it in time, so the fastening screws between the bottom groove and the inlay will not fall off, and thus there will be no hidden danger of falling windows.

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Embodiment 1: Anti-fall window support installation structure

[0032] Please refer to Figure 1-Figure 5 The anti-falling window support installation structure comprises: an anti-falling groove 11 on a frame material 1, a bottom groove 2 of a window support, and an insert 3.

[0033] like Figure 1 As shown, the anti-falling groove 11 on the frame material 1 is bent inward at two opposite edges of the mouth to form a first blocking portion 12 and a second blocking portion 13.

[0034] like Figure 2 , Figure 3 As shown, the window stay bottom groove 2 comprises a main plate body 21, a side plate body 22 bent downward from one side of the main plate body 21, and a protrusion 23 bent outward from the bottom end of the side plate body 22. The window stay bottom groove 2 is preferably made of metal material, more preferably made of alloy material.

[0035] Figure 5 The state after the window stay and frame material 1 are assembled is shown in FIG. Figure 5 As shown, the protruding portion 23 of the window stay bottom groove 2 is placed in the anti-falling groove 11; the insert 3 is embedded between the first blocking portion 12 of the anti-falling groove 11, the main plate body 21 and the side plate body 22 of the window stay bottom groove 2, on the one hand, the insert 3 forms a blocking fit with the first blocking portion 12, and on the other hand, the insert 3 provides an extrusion effect on the side plate body 22 of the window stay bottom groove 2, so that the protruding portion 23 of the window stay bottom groove 2 forms a blocking fit with the second blocking portion 13, and the bottom groove 2 and the insert 3, the bottom groove 2 and the frame material 1 are respectively locked by screws. Thus, the window stay bottom groove 2 will not fall out of the anti-falling groove 11.

[0036] Figure 4The structure of the insert 3 is shown in FIG. The insert 3 is a strip-shaped structure, and the insert 3 has a plurality of through holes 31 for combining the window support bottom groove 2 and the frame material 1, and a plurality of threaded holes 32 for combining the window support bottom groove 2 and the insert 3. The strip-shaped insert 3 increases the matching area between the insert 3 and the first blocking portion 12, and increases the contact area between the insert 3 and the window support bottom groove 2, thereby having a more stable blocking and squeezing effect. The plurality of through holes 31 and threaded holes 32 make the locking operation of the window support bottom groove 2 and the frame material 1, and the window support bottom groove 2 and the insert 3 more convenient, and the locking effect is more secure.

[0037] Using the above-mentioned anti-fall window stay installation structure, the installation method of the window stay and the frame material 1 is as follows: slightly tilt the window stay so that the protrusion 23 on the window stay bottom groove 2 enters the anti-fall groove 11, put the insert 3 into the anti-fall groove 11, push it to the bottom of the main body 21 of the window stay bottom groove 2, and then use a fastening screw to pass through the window stay bottom groove 2 and the through hole 31 on the insert 3 to screw into the frame material 1, lock the window stay bottom groove 2 and the frame material 1, and use a fastening screw to pass through the window stay bottom groove 2 and screw into the threaded hole 32 on the insert 3 to lock the window stay bottom groove 2 and the insert 3, thereby completing the assembly of the window stay and the frame material 1.

[0038] It can be seen that, by adopting the anti-falling window support installation structure, there is no need to reserve a gap in the blocking part on the anti-falling groove 11, and there is no need to align the gap with the protrusion 23 during installation, which avoids the need to hold the entire opening sash to align the protrusion 23 with the gap during installation, greatly facilitating the installation operation. On the other hand, in the above structure, the window support will not fall out of the anti-falling groove 11 even if it slides arbitrarily in the anti-falling groove 11. Therefore, even if the fastening screws between the window support bottom groove 2 and the frame material 1 fall off, there will be no hidden danger of falling windows, and thus it has a better anti-falling window effect.

[0039] In a very extreme case, the above structure may cause a window falling hazard, namely: when the fastening screws between the window support bottom groove 2 and the frame material 1 fall off, the fastening screws between the window support bottom groove 2 and the insert 3 also fall off, and the insert 3 and the window support bottom groove 2 are disengaged, in this case the window support bottom groove 2 will fall out of the anti-fall groove 11, causing a window falling hazard.

[0040] In order to avoid the hidden danger of falling windows in such extreme cases, a gap is further left between the insert 3 and the side plate 22 of the window support bottom groove 2, or between the insert 3 and the side of the anti-falling groove 11. The setting of the above gap enables an early warning signal to be generated after the locking screw between the window support bottom groove 2 and the frame material 1 falls off. Specifically, when the locking screw between the window support bottom groove 2 and the frame material 1 falls off, the window support can slide in the anti-falling groove 11, and the sliding causes the opening sash to be unable to be smoothly closed with the frame material 1 when closing the opening sash, so that the user can know that the opening sash has a fault, that is, the purpose of early warning is achieved, and the user can repair the fault in time. Moreover, the fastening screws between the window support bottom groove 2 and the insert 3 will definitely not fall off before the fastening screws between the window support bottom groove 2 and the frame material 1, because only before the fastening screws between the window support bottom groove 2 and the frame material 1 fall off, the fastening screws between the window support bottom groove 2 and the insert 3 are not subjected to force, so such a design eliminates the hidden danger of falling windows in the above extreme cases.

[0041] like Figure 5 As shown, in this embodiment, the assembly between the sash material 5 and the window stay D arm 4 adopts the existing assembly method, that is, the D arm 4 is embedded in the anti-fall groove on the sash material 5 and locked by fastening screws.

[0042] Embodiment 2: Window support

[0043] like Figure 6 As shown, the window stay includes not only a bottom groove 2 for assembling with the frame material and a D arm 4 for assembling with the sash material, but also an insert 3.

[0044] Reference Figure 2 , Figure 3 The bottom tank 2 includes a main plate body 21 , a side plate body 22 bent downward from one side of the main plate body 21 , and a protrusion 23 bent outward from the bottom end of the side plate body 22 .

[0045] Reference Figure 5 The insert 3 is used to be embedded between the main plate body 21 and the side plate body 22 of the anti-fall groove 11 and the window support bottom groove 2, forming a blocking fit with the blocking portion (the first blocking portion 12) at one edge of the anti-fall groove 11, and squeezing the window support bottom groove 2 so that the protrusion 23 forms a blocking fit with the blocking portion (the second blocking portion 13) at the other edge of the anti-fall groove 11.

[0046] Reference Figure 4 The insert 3 adopts a strip structure, and has a plurality of through holes 31 for combining the window support bottom groove 2 and the frame material 1, and a plurality of threaded holes 32 for combining the window support bottom groove 2 and the insert 3.

[0047] In summary, the present invention solves the technical problems of the existing anti-falling window support installation structure, such as the difficulty in installation and the failure to eliminate the hidden danger of falling windows, by adding an insert 3 and improving the window support bottom groove 2, and only configuring a protrusion 23 on one side of the window support bottom groove 2. Moreover, the present invention has an early warning function.

[0048] The present invention is described in detail above through specific embodiments, and these detailed descriptions are only limited to helping those skilled in the art understand the content of the present invention, and cannot be understood as limiting the scope of protection of the present invention. Various modifications, equivalent transformations, etc. made by those skilled in the art to the above scheme under the conception of the present invention should be included in the scope of protection of the present invention.
