Description

Technical Field

[0001] This utility model relates to the field of window hinges, and more particularly to a suspension support device. Background Technology

[0002] In reversible windows that can be opened in both casement and outward directions, the opening sash typically uses hinges to achieve the opening and outward movement. For example, the opening sash can utilize the support rocker arm disclosed in CN104832015A to switch between casement, outward, and closed states. When the opening sash is in the outward-opening state, its weight is supported solely by this support rocker arm. However, the opening sash is heavy, especially given the increasing demand for sound insulation leading to thicker glass and sealing strips. Relying solely on the support rocker arm for support can easily cause deformation and wear over time. Therefore, current support rockers are often made of increasingly thick and heavy materials. Ultimately, this results in a larger and heavier support rocker arm, making installation more difficult. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a suspension support device.

[0004] This utility model is achieved by the following technical solution: a suspension support device, including a support part and an abutment part, wherein the support part is fixed on the window frame, the abutment part is fixed on the opening sash, one end of the support part extends outward from the window frame, and the abutment part abuts against the support part when the opening sash is in the suspended state.

[0005] The support includes a first mounting plate, which is fixed to the inner wall of the window frame. A support member is rotatably connected to the first mounting plate, and the abutment part engages with the support member when the opening sash is suspended.

[0006] The support member includes a support plate and a tension spring. The support plate is rotatably connected to the first mounting plate. A limiting post is provided on the end face of the support plate facing the first mounting plate. A limiting groove is opened on the first mounting plate. The limiting post is inserted into the limiting groove. When the support plate rotates, the limiting post reciprocates within the limiting groove.

[0007] A tension spring is provided between the first mounting plate and the limiting post. One end of the tension spring is fixed to the limiting post, and the other end of the tension spring is fixed to the first mounting plate. When the opening fan is in the suspended state, the abutting part abuts against the support plate.

[0008] The support plate has a recess, and when the opening fan is in the suspended state, the abutting part abuts against the recess of the support plate.

[0009] The abutting part includes a second mounting piece, which is fixed on the opening fan. The second mounting piece is provided with an abutting post, and when the opening fan is in the downward-opening state, the abutting post engages with the support piece.

[0010] The second mounting piece has a mounting protrusion in the middle facing the first mounting piece. A cavity is formed between the mounting protrusion and the opening fan. A bolt hole is provided on the mounting protrusion. The abutment post is threaded into the bolt hole. The cavity allows the abutment post to extend out.

[0011] The mounting end face is provided with an outwardly extending mounting post, and the tension spring is fixed on the mounting post.

[0012] Compared to existing technologies, this invention, when the opening fan is in the downward-opening state, returns to its original position as the fan opens outwards. The tension spring, acting as a return spring, pulls the limiting post until it abuts against the end of the limiting groove. At this point, the support plate rotates outwards, causing its recess to rotate until it is positioned below the abutting post, supporting the abutting post. This, combined with the original hinge of the opening fan, provides support for the downward-opening function of the fan, reducing the support pressure on the original hinge. Therefore, it can accommodate heavier downward-opening fans without requiring modifications to the original hinge, simplifying installation. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Reference Figure 1-4 A suspension support device is disclosed, which works in conjunction with the existing hinges on the operable sash 4. This suspension support device supports the operable sash 4 when it is in the outward-opening, suspended state. The suspension support device includes a support part 1 and an abutment part 2. The support part 1 is fixed to the window frame 3, and the abutment part 2 is fixed to the operable sash 4. One end of the support part 1 extends outward from the window frame 3. When the operable sash 4 is in the suspended state, the abutment part 2 abuts against the support part 1. In actual installation, the abutment part 2 is installed above the operable sash 4, i.e., away from the original hinges of the operable sash 4. When the operable sash 4 is in the downward-opening, outward-opening state, the original hinges and the suspension support device jointly support the weight of the operable sash 4. Specifically, when the operable sash 4 is in the downward-opening, outward-opening state, the support part 1 extends from the inside of the window frame 3 to form a support area, and the abutment part 2 directly abuts against the support part 1 to support the operable sash 4.

[0020] In this embodiment, the support part 1 includes a first mounting plate 11, which is fixed to the inner wall of the window frame 3. A support member is rotatably connected to the first mounting plate 11. When the sash 4 is suspended, the abutment part 2 engages with the support member. In this embodiment, the support member can rotate around a central point. Specifically, the support member in this embodiment includes a support plate 12 and a tension spring 14. The support plate 12 is rotatably connected to the first mounting plate 11. A limiting post 15 is provided on the end face of the support plate 12 facing the first mounting plate 11. A limiting groove 13 is formed on the first mounting plate 11. The limiting post 15 is inserted into the limiting groove 13. When the support plate 12 rotates, the limiting post 15 reciprocates within the limiting groove 13. To ensure that the support plate 12 can return to its original position after rotation, a tension spring 14 is provided between the first mounting plate 11 and the limiting post 15. One end of the tension spring 14 is fixed to the limiting post 15, and the other end of the tension spring 14 is fixed to the first mounting plate 11. When the opening fan 4 is in the downward-hanging state, the abutment part 2 abuts against the support plate 12. A recess can be provided on the support plate 12, and when the opening fan 4 is in the downward-hanging state, the abutment part 2 abuts against the recess of the support plate 12. When in use, the opening fan 4 expands outward, losing its abutment against the support plate 12. Then, the support plate 12 moves to the other end of the limiting groove 13 under the pull of the tension spring 14 and finally abuts against the end of the limiting groove 13. At this time, the opening fan 4 rotates outward to the maximum angle, and the abutment part 2 fixed on the opening fan 4 is above the recess. Then, when the opening fan 4 slightly moves inward to the support angle, the abutment part 2 directly abuts against the recess, thus supporting the opening fan 4 together with the original hinge at the bottom of the opening fan 4, sharing the weight of the opening fan 4, reducing the support pressure of the original hinge. That is, it can adapt to the downward-hanging outward opening of the heavier opening fan 4 without modifying the original hinge, making the installation simpler.

[0021] In this embodiment, the abutting part 2 includes a second mounting piece 21, which is fixed on the opening fan 4. The second mounting piece 21 is provided with an abutting post 22. When the opening fan 4 is in the downward-suspension open state, the abutting post 22 engages and abuts against the support piece 12.

[0022] Specifically, in this embodiment, the installation method between the abutment post 22 and the second mounting plate 21 can be such that a mounting protrusion facing the first mounting plate 11 is formed in the middle of the second mounting plate 21, and a cavity is formed between the mounting protrusion and the opening fan 4. Bolt holes are opened on the mounting protrusion, and the abutment post 22 is threaded into the bolt holes, with the cavity allowing the abutment post 22 to protrude. Therefore, during installation, the length of the abutment post 22 protruding from the second mounting plate 21 can be adjusted by rotating the abutment post 22 to adapt to different installation requirements. Furthermore, even if there is an error in the position between the abutment post 22 and the support plate 12 during installation, fine-tuning can be achieved by adjusting the length of the abutment post 22, making adjustment more convenient.

[0023] Compared to existing technologies, in this invention, when the opening fan 4 is in the downward-opening state, the tension spring 14 returns to its original position as the opening fan 4 opens outwards. The tension spring 14, with its returning force, pulls the limiting post 15 until it abuts against the end of the limiting groove 13. At this time, the support plate 12 rotates outwards, causing its recess to rotate until it is positioned below the abutment post 22, supporting the abutment post 22. This, together with the original hinge of the opening fan 4, supports the downward-opening of the opening fan 4, thereby reducing the supporting pressure on the original hinge. In other words, it can accommodate the heavier downward-opening opening of the opening fan 4 without requiring modifications to the original hinge, making installation simpler.

[0024] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
