Description

Technical Field

[0001] The invention relates to a transmission mechanism for a side-moving tilt-down window. Background Art

[0002] In architecture, a window refers to an opening built on a wall or roof to allow light or air to enter a room. Modern windows are mainly composed of three parts: window frames, glass, and movable components (hinges, handles, pulleys, etc.). The window frame is responsible for supporting the main structure of the window, which can be made of wood, metal, ceramic or plastic. The transparent part is set on the bed and connects the sash to the window frame. The transparent part can be made of paper, cloth, silk or glass. The movable components are mainly made of metal materials, and may be wrapped with insulating materials such as plastic in places where people can touch them. Existing windows can be designed as casement windows, sliding windows, etc. The casement windows connect the window sashes to the window frames through hinges and are opened by rotating the window sashes. They can be 100% opened and have good airtightness when closed, but they need to occupy a large indoor or outdoor space when opened and are not suitable for use in some narrow spaces; the sliding windows slide the window sashes equipped with pulleys on the tracks on the window frames. They do not occupy additional space regardless of whether they are in the open or closed state, and their structure is relatively simple, but at most only 50% of the window sashes can be opened, and the airtightness is poor when closed; the side-sliding inward-tilting windows do not occupy too much additional space, have a large opening space, and have good airtightness when closed, but the existing side-sliding inward-tilting windows do not slide smoothly, are prone to vibration when tilted inward, and are prone to left and right movement after closing.

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1As shown, two groups of transmission mechanisms for opening, closing or tilting the window sashes are arranged between the frame and the window sash of the sideways-moving and inward-tilting window of the present invention, each group of transmission mechanisms includes a fixing seat 1 fixedly mounted on the window sash, a short connecting rod 2 for tilting the window sashes inwards, a long connecting rod 3 for opening and sideways-moving the window sashes, and a first locking device for locking or unlocking the short connecting rod 2, one end of the short connecting rod 2 is hinged to the fixing seat 1, and the other end is hinged to one end of the long connecting rod 3, the other end of the long connecting rod 3 is hinged to a first sliding block 4, a sliding rail is fixedly mounted on the frame, and the first sliding block 4 is mounted on the sliding rail and slides along the sliding rail. When the window sash is opened for sideways movement, the first locking device locks the short connecting rod on the fixed seat and does not move with the long connecting rod, causing the window sash to deviate from the frame. At this time, the window sash can slide smoothly along the track on the frame to open the entire window sash horizontally to allow indoor and outdoor air to circulate over a large range. When the window sash needs to be tilted inward, it is only necessary to unlock the first locking device to allow the short connecting rod to rotate with the long connecting rod, so that the distance above the window sash deviates from the frame is greater than the distance below the window sash deviates from the frame, allowing indoor and outdoor air to circulate over a small range.

[0027] like Figure 2 As shown, the first locking device comprises a third slide groove 61 provided below the fixed seat 1, a second slider 62 installed in the third slide groove 61 and sliding along the third slide groove 61, a sliding shaft 63 installed above the second slider, and a fourth slide groove 64 provided on the fixed seat 1, the sliding shaft 63 is provided in the fourth slide groove 64 and slides along the fourth slide groove 64, the fourth slide groove 64 is provided just above the third slide groove 61, and an opening 65 is provided at one end of the fourth slide groove 64 for the sliding shaft 63 to slide out of the fourth slide groove 64. When working, the second slider slides in the third slide groove, thereby driving the sliding shaft to slide in the fourth slide groove. When locked, the sliding shaft is located in the fourth slide groove and away from the opening, so that the short connecting rod does not follow the long connecting rod under the restriction of the sliding shaft. When unlocked, the sliding shaft is provided at the end of the fourth slide groove and faces the opening, and the short connecting rod moves under the action of the long connecting rod. At this time, the sliding shaft is separated from the fourth slide groove at the opening, that is, the short connecting rod is separated from the restriction of the sliding shaft, and the window sash is tilted inward.

[0028] The two second sliders 62 of the two groups of first locking devices are connected, that is, they are connected to the two second sliders at the same time through a connecting rod, so that the first locking devices of the two transmission mechanisms move together, unlock and lock at the same time.

[0029] The fixing seat 1 is provided with a guide groove 66 whose cross section is trapezoidal. One end of the second slider 62 is provided with a guide rod 67 which matches the guide groove 13 and plays a good guiding role, so that the second slider and the sliding shaft can slide smoothly and avoid jamming.

[0030] like Figure 3As shown, each group of transmission mechanisms also includes a second limiting device for limiting the long connecting rod, the second limiting device includes a fixed block 71 fixedly mounted on the fixed seat 1, a movable block 72 movably mounted above the fixed block 71, springs at both ends respectively abutting against the fixed block 71 and the movable block 72, and a first roller 73 fixedly mounted on the end of the long connecting rod 3, the first roller 73 abuts against the movable block 72, and the end of the movable block 72 for the first roller to abut is set as an arc surface to facilitate the first roller to slide over. When the window sash is opened or closed, that is, when the long connecting rod rotates, the first roller on the long connecting rod presses the movable block to overcome the spring elastic force and move until the first roller is separated from the movable block. At this time, the movable block is reset under the action of the spring elastic force, and the long connecting rod is limited by the movable block, and the movable block will not be pressed to move due to a small external force, thereby preventing the window sash from opening or closing automatically.

[0031] A receiving groove 74 for accommodating a spring and a fixed block 71 is provided in the middle of the movable block 72. The fixed block 71 is a T-shaped block, and the receiving groove 74 is a T-shaped groove that matches the T-shaped block to limit the installation of the movable block; a plurality of guide shafts 77 are integrally formed in the receiving groove, and the guide shaft 77 is a semicircular shaft. A guide hole that matches the guide shaft 77 is provided on the fixed block 71, so that it plays a guiding role when the movable block moves, so that the movable block slides smoothly; a plurality of convex strips are integrally formed at the bottom of the movable block, and the convex strips abut against the surface of the fixed seat to reduce the friction between the movable block and the fixed seat, so that the movable block slides smoothly.

[0032] A limit rod 75 is fixedly installed on the above-mentioned fixed seat 1, and a limit block 76 extends outward from the end of the movable block 72. The limit block 76 abuts against the limit rod 75 under the action of spring elastic force, plays a limiting role, limits the original position of the movable block, and prevents the movable block from detaching from the fixed block.

[0033] The above-mentioned fixed seat 1 extends upward with a support block 11, and a first groove is opened at one end of the support block 11. A support shaft 31 is provided on the long connecting rod 3 to slide into the first groove. The first groove 12 is an arc groove that matches the support shaft 31. When the support shaft slides into the first groove, it acts as a fulcrum, making it easier to open or close the long connecting rod and acting as a lever.

[0034] A first limiting device for limiting the inward tilting of the window sash is provided on one of the transmission mechanisms. The first limiting device includes a limiting link 51 with one end hinged to the middle part of the long link 3, a sliding rod 52 fixedly mounted on the short link 2, and a second locking device for locking the limiting link. A first sliding groove 53 cooperating with the sliding rod 52 is provided at the other end of the limiting link 51. The sliding rod 52 is arranged in the first sliding groove 53 and slides along the first sliding groove 53. Under the cooperation of the limiting link, the sliding rod and the second locking device, the window sash is limited when it is tilted inward to prevent the window sash from vibrating.

[0035] A positioning stepped shaft is integrally formed above the slide rod 52 , and the diameter of the positioning stepped shaft is larger than the width of the first slide groove 53 . The end face of the positioning stepped shaft abuts against the limiting link to limit the limiting link and prevent the limiting link from detaching from the slide rod.

[0036] The second locking device includes a locking sleeve 54 sleeved on the limit link 51, the locking sleeve is a plastic part, and is covered on the limit link 51. A positioning shaft 57 is integrally formed on the locking sleeve, and a positioning hole matching the positioning shaft 57 is provided on the limit link 51 to achieve the positioning installation of the locking sleeve and the limit link; the locking sleeve 54 is provided with a second slide groove 55 matching the slide bar 52, the groove width of the second slide groove 55 is smaller than the groove width of the first slide groove 53, and is slightly larger than the slide bar diameter. The second slide groove 55 is arranged opposite to each other. There are locking protrusions 56 on the side walls that protrude into the groove, and the distance between the two locking protrusions 56 is smaller than the diameter of the slide bar 52. The second slide groove 55 is divided by the locking protrusions 56 into a locking area 551 for locking the slide bar 52 and a sliding area 552 for the slide bar 52 to slide freely. When the slide bar is in the sliding area, the slide bar can slide freely in this area. When the slide bar slides into the locking area through the locking protrusions under the action of external force, the limit link is limited, so that the window sash will not be automatically closed due to a small external force, which plays a shock-proof role and allows the inward tilt to open smoothly.

[0037] like Figure 4 As shown, another group of transmission mechanisms is provided with an anti-movement device for preventing the window sash from moving, that is, the anti-movement device and the above-mentioned first limiting device are respectively arranged on different transmission mechanisms, and the anti-movement device includes an anti-movement block 81 fixedly mounted on the frame, a second roller 82 fixedly mounted on the first slider 4, and a third roller 83 fixedly mounted on the middle part of a long connecting rod 3. The anti-movement block 81 is located near the end of the slide rail, and a protrusion 84 is arranged on the anti-movement block 81. When the window sash is closed, the second roller 82 and the third roller 83 respectively abut against the two ends of the protrusion 84 to prevent the window sash from moving left and right when closed, thereby improving the sealing.

[0038] The protrusion 84 is provided with a second groove 85 for accommodating and limiting the second roller 82. The second groove 85 is an arc groove, that is, when the window sash is closed, the first slider slides to the end of the slide rail, and the second roller also slowly slides into the second groove to play a limiting role.

[0039] Finally, it should be noted that the above embodiments only illustrate the technical solutions of the present invention, rather than limiting it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
