Description

Technical Field

[0001] The invention relates to the technical field of windows, in particular to a tightly closable side-pull structure for doors, windows and cabinets. Background Art

[0002] The advantage of side sliding windows is that the window sash does not need to be pushed out of the window or pulled in, which saves space and is very popular. Of course, this structure is also commonly used in doors, cabinets, etc.

[0003] Traditional side-sliding windows (also called sliding windows and push-pull windows) are provided with two movable window sashes, and the two window sashes are fixed on two sets of parallel guide rails. In this way, one of the window sashes can be moved to open the window when ventilation is needed. The shortcomings of the above technical solution are: the two window sashes need to slide smoothly and parallel along the guide rails, so there must be a gap between the two parallel window sashes, and wind, rain, dust, insects, etc. can easily enter the room through this gap, and the sound insulation effect is poor. If the air conditioner, electric heater and other equipment are turned on in the room, heat will be quickly exchanged with the outside world, resulting in increased energy consumption. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a side-sliding window structure which can make a window (or a door, a cabinet door or other structure) relatively airtight when closed.

[0005] The technical solution of the present invention is:

[0006] A closable side-pull structure for door, window and cabinet, characterized in that it comprises a frame, a fixed window sash and a movable window sash, the junction of the fixed window sash and the movable window sash is a mutually matching inclined surface and a latch that can lock the two is arranged on the inclined surface, grooves are arranged in the frame for matching the fixed window sash and the movable window sash at the upper and lower parts, wherein the fixed window sash is fixedly installed on the left side of the groove through a connecting piece (this is only an example, and installing it on the right side does not hinder the solution of the technical problem described in the technical solution), the front and rear end surfaces of the groove are respectively provided with a front guard plate and a rear guard plate, the rear end of the fixed window sash is close to the rear guard plate, and a gap is left between the fixed window sash and the front guard plate to form a guide rail that is convenient for the load-bearing wheels of the movable window sash to travel, and the upper and lower sides of the movable window sash are both provided with a first support member and a second support member, and the first support member is installed on the movable At one end of the inclined surface of the window sash, a second support member is installed at the non-inclined end of the movable window sash, and the structural difference between the first support member and the second support member is the different installation positions. The first support member includes a connecting rod connected to the movable window sash, a load-bearing wheel installed at the bottom of the connecting rod, and a first guide wheel installed on the side wall of the connecting rod. A guide plate that is triangular in top view is provided on the right side of the groove (in order to facilitate illustration, the guide plate is not in contact with the load-bearing wheel of the second support member in the figure. It can be understood that in order to fix the right end of the movable window sash, the guide plate must be close to the second support member of the movable window sash to support it, so that the right end of the movable window sash is not easy to move. When the left end of the movable window sash is fixed by a latch, the movable window sash is fixed and the inclined surfaces of the two window sashes are tightly fitted to prevent wind, rain, dust, insects, etc. from entering the room).

[0007] As a further improvement of the present invention, the frame material is aluminum profile, and the skeleton of the fixed window sash and the movable window sash is also made of aluminum profile. The inclined surfaces of the two are made of wear-resistant profile. The aluminum profile is waterproof, rust-proof and has a long service life. In addition, the overall strength is also high. In addition, the aluminum profile can also be replaced with wood, copper, stainless steel, plastic, synthetic resin and other materials.

[0008] In some embodiments, a limit plate is provided on the groove and on the front end surface of the fixed window sash, so that the load-bearing wheels can move more smoothly on the guide rail, reducing the chance of scratching the fixed window sash.

[0009] Specifically, at least one handle is provided on the movable window sash to facilitate pushing and pulling the window sash.

[0010] Specifically, a second guide wheel is provided on the inclined surfaces of the upper and lower sides of the fixed window sash corresponding to the movable window sash. Since the inclined surfaces of the two are closely fitted and the static friction is large, it is difficult for the user to manually pull it open. By providing the first guide wheel and adding the second guide wheel, the friction between the two inclined surfaces can be reduced to a certain extent, making it easier for the user to pull.

[0011] In order to further improve the airtightness, several sealing strips can be vertically glued to the tip of the fixed window sash slope. When the two window sashes are closed, the sealing effect can be further improved. When the window is opened, one window sash overlaps the other window sash, and the ventilation volume is the same as that of an ordinary side-sliding window.

[0012] In other embodiments, two movable window sashes are arranged in the same frame. The two movable window sashes are arranged opposite to each other, and the fixed window sash only retains a triangular area between the two movable window sashes for installing the second guide wheel. The advantage is that both windows can be opened.

[0013] Specifically, the angle formed by the inclined surface of the fixed window sash and the plane of the fixed window sash is 20°-60°. It can be understood that the opening and closing of the movable window sash depends on the turning effect of the inclined surface on it, and an adaptive angle should be selected according to the movable window sash of different thicknesses. For example, if the movable window sash is thicker, the angle should be larger, and if the movable window sash is thinner, the angle should be smaller.

[0014] Although the specification and drawings (and their descriptions) of the present invention only illustrate the case of one fixed window sash and one movable window sash, it is conceivable that: when the first movable window sash is fixed, it can obviously be used as a fixed window sash for the next movable window sash. Then it can be understood that the present invention can be provided with two movable window sashes, three movable window sashes or even multiple movable window sashes, and its operation does not exceed the protection scope of the present invention and should be included in the rights and interests of the applicant in accordance with the law.

[0015] The beneficial effects of the present invention are as follows: flexible opening and closing and smooth sliding, when closed, the inclined surfaces of the two window sashes are in close contact with each other and at this time the two window sashes are almost on the same plane, different in appearance from ordinary side-sliding windows but similar to casement windows, reducing the possibility of air, dust, etc. passing through, improving the sealing effect, and having the effect of resisting wind, rain, haze, wind, sand, sandstorms, etc.; and when the window is opened, after one of the window sashes overlaps the other window sash, the ventilation volume is the same as that of an ordinary side-sliding window, and since the possibility of air flow is reduced, it has a sound insulation effect; it can be suitable for use in various buildings, houses, vehicles, windows, display cabinets, wardrobes, lockers and other occasions.

[0016] When the present invention is used in a room with an air conditioner or an electric heater, the sealing effect is better than that of a traditional side-sliding window, which reduces the possibility of air exchange, objectively reduces the speed of heat exchange between the room and outside the room, and reduces the energy consumption of the air conditioner or electric heater.

[0017] In addition, it is worth mentioning that, since the present invention is tighter and stronger than a general side-sliding window when used as a window, and there is no risk of the sash of the casement window falling off, it is very suitable as a window for high-rise buildings and has excellent safety performance.

DETAILED DESCRIPTION

[0026] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[0027] Example 1

[0028] like Figure 1-5As shown, a closable side-pull structure for door and window cabinets is characterized in that: it includes a frame, a fixed window sash and a movable window sash, the junction of the fixed window sash and the movable window sash is a matching inclined surface and a latch that can lock the two is arranged on the inclined surface, and grooves are arranged in the frame to match the fixed window sash and the movable window sash at the upper and lower parts, wherein the fixed window sash is fixedly installed on the left side of the groove through a connecting piece (this is only an example, and installing it on the right side does not hinder the solution of the technical problem described in the technical solution), and the front and rear end surfaces of the groove are respectively provided with a front guard plate and a rear guard plate, the rear end of the fixed window sash is close to the rear guard plate, and a gap is left between the fixed window sash and the front guard plate to form a guide rail that is convenient for the load-bearing wheels of the movable window sash to travel, and the upper and lower sides of the movable window sash are both installed with a first support member and a second support member, and the first support member is installed on At one end of the inclined surface of the movable window sash, a second support member is installed at the non-inclined end of the movable window sash, and the structural difference between the first support member and the second support member is the different installation positions. The first support member includes a connecting rod connected to the movable window sash, a load-bearing wheel installed at the bottom of the connecting rod, and a first guide wheel installed on the side wall of the connecting rod. A guide plate that is triangular in top view is provided on the right side of the groove (in order to facilitate illustration, the guide plate does not contact the load-bearing wheel of the second support member in the figure. It can be understood that in order to fix the right end of the movable window sash, the guide plate must be close to the second support member of the movable window sash to support it, so that the right end of the movable window sash is not easy to move. When the left end of the movable window sash is fixed by the latch, the movable window sash is fixed and the inclined surfaces of the two window sashes are tightly fitted to prevent wind, rain, dust, insects, etc. from entering the room).

[0029] The latch here is a prior art and is commonly used in doors and windows. For example, the structure, use method and application of the latch on both sides of the side sliding window can be referred to in the specification and drawings of the Chinese patent for a side sliding window structure, patent number 98208127.8. This article will not elaborate on it.

[0030] Specifically, the angle formed by the inclined surface of the fixed window sash and the plane of the fixed window sash is 20°-60°. It can be understood that the opening and closing of the movable window sash depends on the turning effect of the inclined surface on it, and an adaptive angle should be selected according to the movable window sash of different thicknesses. For example, if the movable window sash is thicker, the angle should be larger, and if the movable window sash is thinner, the angle should be smaller.

[0031] Example 2

[0032] The frame is made of aluminum profile, and the skeletons of the fixed window sash and the movable window sash are also made of aluminum profile. The inclined surfaces of the two are made of wear-resistant profile. The aluminum profile is waterproof, rust-proof, has a long service life, and has high overall strength. The other structures of this embodiment are the same as those of embodiment 1.

[0033] Example 3

[0034] like Figure 2As shown, a limit plate is provided on the groove and on the front end surface of the fixed window sash, so that the load-bearing wheel can move on the guide rail more smoothly, reducing the chance of scratching the fixed window sash. The other structures of this embodiment are the same as those of the first embodiment.

[0035] Example 4

[0036] The movable window sash is provided with at least one handle for facilitating pushing and pulling the window sash. The other structures of this embodiment are the same as those of the first embodiment.

[0037] Example 5

[0038] The upper and lower sides of the fixed window sash are provided with second guide wheels on the inclined surfaces corresponding to the movable window sash. Since the inclined surfaces of the two are closely fitted, the static friction is relatively large, and it is difficult for the user to manually pull it open. By providing the first guide wheel and adding the second guide wheel, the friction between the two inclined surfaces can be reduced to a certain extent, so that the user can pull it easily. The other structures of this embodiment are the same as those of embodiment 1.

[0039] Example 6

[0040] A plurality of sealing strips are vertically bonded to the tip of the fixed window sash bevel, which can further improve the sealing effect when the two window sashes are closed, and when the window is opened, one window sash overlaps the other window sash, and the ventilation volume is the same as that of an ordinary side-sliding window. The other structures of this embodiment are the same as those of embodiment 1.

[0041] The technical features of the above-mentioned embodiments can be freely combined without conflict.

[0042] The method of using the present invention is described here using Example 4 as an example, see Figure 6 .

[0043] Open: hold the handle and pull the movable window sash to the front left. The front inclined surface of the movable window sash slides against the inclined surface of the fixed window sash, causing the entire movable window sash to tilt. Since there is a large space on the right side of the groove (the gap between the front and rear guard plates is large), the support at the right end of the movable window sash can move obliquely to the left; and then the load-bearing wheels of the movable window sash are guided by the inclined surface into the guide rail between the fixed window sash and the front guard plate. When the load-bearing wheels of the two support parts enter the guide rail, the two window sashes are parallel, so the ventilation volume is no different from that of ordinary side-sliding windows.

[0044] Close: Hold the handle and push the movable window sash to the right. The second supporting member of the movable window sash moves to the right and is influenced by the guide plate to tilt to the right rear. When the right end of the movable window sash reaches the right end of the groove, manually push the inclined surface of the movable window sash and the inclined surface of the fixed window sash into close contact. At this time, the latch is locked. Since both ends of the movable window sash are fixed, the window is in a sealed state.

[0045] Example 7

[0046] like Figure 7 As shown, two movable window sashes are arranged in the same frame, and the two movable window sashes are arranged opposite to each other. The fixed window sash only retains a triangular area between the two movable window sashes for installing the second guide wheel, which has the advantage that both windows can be opened.

[0047] The above embodiments and descriptions are only for illustrating the principles and best embodiments of the present invention. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and improvements, all of which fall within the scope of the present invention to be protected.
