Description
Technical Field
The present invention relates to an opening assist device for a sliding window, and more particularly, to an opening assist device for a sliding window, in which a locking member is rotated by rotating a handle so that the locking member is released from a locked state, and in which a sash frame is separated from a sash frame in an opening direction by rotation of an arm so as to be easily opened.
Background
Generally, various windows are provided in the interior and exterior of a building for access control and lighting purposes.
Herein, the window may be classified into a sliding type, a hinge type, and a fixed type according to opening and closing methods. Among them, the sliding type is mainly applied to windows having medium and large sizes installed in a living room and/or a balcony of a house.
In such a sliding window, when a user grasps a handle provided at a sash frame and pushes or pulls the handle to one side, a roller at a lower end of the sash frame rotates along a track on a window frame, and thus the sliding window slides in a lateral direction and is opened or closed.
Recently, in the case of a middle-sized or large-sized sliding window, in order to improve heat insulation performance, glass or multiple glass having a larger thickness is applied to a sash frame as compared to a conventional sliding window, and thus a load of the sash frame is considerably large. In addition, since the airtight unit is applied between the window sash frame and the window frame in order to improve blocking performance against noise and inflow of outdoor air, the window sash frame and the airtight unit are in close contact with each other, and it is difficult to slide the window sash frame by pushing or pulling while grasping the handle, thereby causing inconvenience in opening the window sash frame.
In order to solve such a problem, a technique disclosed in korean utility model publication No.20-2010-0012532 (publication date: 12/17/2010) has been proposed.
Korean utility model publication No.20-2010-0012532 discloses a handle interlock type opening apparatus for a sliding window, in which a rack for the opening apparatus is formed on a sliding bar having a rack engaged with a pinion gear combined with a handle installed to operate a locking apparatus, and a sash frame is separated from a door frame in front of the rack for the opening apparatus, the opening apparatus including: a body fixed to the window sash frame in a state of being inserted into the rail groove; an arm assembled with the main body by an arm pin so as to be rotatable and having a plurality of pinion protrusions engaged with a rack for an opening device formed on the slide lever; a roller assembled with the front end of the arm; and a leaf spring installed to contact the vertical portion of the arm in a state where the leaf spring is fixed to the body to elastically support the arm located within the body.
In the korean utility model publication No.20-2010-0012532 having the above-mentioned configuration, when the handle provided on the window frame is rotated, the arm is rotated together with the handle to separate the window frame from the door frame, so that the opening of the middle-or large-sized sliding door can be easily performed.
However, in korean utility model publication No.20-2010-0012532, since an opening device operated by a handle and a locking device are separately provided, the opening device has a complicated structure and causes complexity in manufacturing and installation, and since the opening device is operated after an operation of releasing the locking device, it takes a considerable time to operate the opening device.
In view of the above-described problems, development of an opening assisting device for a sliding window that can shorten the time taken to operate the opening device while having a simple structure has been conducted, but satisfactory results have not been obtained yet.

Detailed Description
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. As exemplarily shown in fig. 1 to 3, the opening assistance device a for a sliding window according to the present invention includes a housing 10, a rotation member 20, an arm 30, a locking member 40, and a cover 50.
A space is formed inside the housing 10.
The rotation member 20, the arm 30 and the locking member 40 may be disposed within the housing 10 by forming a space within the housing 10.
The housing 10 is installed in a side of the sash frame 200 adjacent to the inner surface of the window frame 100.
By installing the housing 10 in one side of the window sash frame 200, the central shaft 310 of the handle 300 installed at one side of the window sash frame 200 is combined with the rotation member 20 installed in the housing 10, so that the rotation member 20 can be rotated by the rotation of the handle 300.
In addition, the housing 10 may be coupled to the window sash frame 200 by screws (no reference numeral).
By coupling the case 10 with the window sash frame 200 by the screws, the case 10 may be separated from the window sash frame 200, and the coupled state between the case 10 and the window sash frame 200 may be securely maintained.
The rotating member 20 may be disposed in the inner space of the housing 10 so as to be rotatable.
The rotation member 20 may have a through-hole 21 formed at the center thereof such that the central shaft 310 of the handle 300 is inserted into the through-hole 21.
The handle 300 and the rotary member 20 are coupled by inserting the central shaft 310 of the handle 300 into the through hole 21 of the rotary member 20, so that the rotary member 20 can be rotatable by the rotation of the handle 300.
Herein, the through-hole 21 may be formed to have a polygonal shape, such as a rectangular shape.
Since the through hole 21 has a polygonal shape, if the central shaft 310 of the handle 300 has a polygonal shape and is inserted into the through hole 21, the central shaft 310 inside the through hole 21 is prevented from idling during the rotation of the handle 300, and thus the rotation member 20 is smoothly rotated by the rotation of the handle 300.
In addition, a plurality of gear teeth 22 formed at designated intervals may be provided on the outer circumferential surface of the rotating member 20.
By forming the gear teeth 22 on the outer circumferential surface of the rotating member 20, the rotating member 20 is rotated in a state where the gear teeth 22 are engaged with the gear teeth 31 formed on the outer circumferential surface of one end of the arm 30, which will be described later, so that the arm 30 can be rotated.
The arm 30 is disposed adjacent to the rotation member 20, and when the rotation arm 30 by the rotation member 20 is rotated, one end of the arm 30 exposed to the outside of the housing 10 protrudes toward the inner surface of the window frame 100.
The arm 30 may include one or more gear teeth 31, the one or more gear teeth 31 being provided on an outer circumferential surface of an end of the arm 30 located within the housing 10.
By forming the gear teeth 31 provided on the arm 130, the gear teeth 31 are engaged with the gear teeth 22 of the rotating member 20, so that the rotating arm 30 by the rotating member 20 can be rotated.
The arm 30 may include a roller 32, and the roller 32 is disposed at one end of the arm 30 exposed to the outside of the housing 10.
By forming the roller 32 on the arm 30, when one end of the arm 30 protrudes toward the inner surface of the window frame 100 and contacts the inner surface of the window frame 100, damage to the window frame 100 is prevented by the rotation of the roller 32.
here, a U-shaped groove 32a is formed on the outer circumferential surface of the roller 32.
By forming the U-shaped groove 32a on the roller 32, the rail 110 formed on the inner surface of the window frame 100 is received in the U-shaped groove 32a, and thus, although the rail 100 is disposed on the inner surface of the window frame 100, the contact between the arm 30 and the inner surface of the window frame 100 is stabilized.
In addition, one end of the arm 30 located inside the housing 10 is elastically supported by an elastic member 33.
By elastically supporting the arm 30 by means of the elastic member 33, the elastic force of the elastic member 33 is applied to the arm 30 in a state where the end of the arm 30 protrudes toward the inner surface of the window frame 100, thereby automatically restoring the end of the arm 30 to its previous state before the protrusion.
Here, since the elastic force of the elastic member 33 is smaller than the external force applied to the rotation member 20 and the arm 30 by the rotation of the handle 300, the elastic force acts only in a state where the external force is not applied to the rotation member 20 and the arm 30, that is, when the non-rotated state of the handle 300 is maintained from when the handle 300 is converted from the rotated state to the previous state.
The locking mechanism 40 is disposed adjacent to the rotating member 20, is rotated by the rotating member 20, and is released from its locked state.
When the movable member 60 is lowered by the rotation of the rotating member 20 to release the locking of the lock mechanism 40 with the stopper 70, the lock mechanism 40 is released from the locked state.
Therefore, when the rotating member 20 is not rotated and the movable member 60 is in the lifted state, the stopper 70 is locked with the locking mechanism 40, so that the locked state of the locking mechanism 40 is maintained.
Herein, the ring portion 41 of the front end of the locking member 40 in the locked state is inserted into the striker 120 fixed to the inner surface of the window frame 100, thereby preventing the sash frame 200 from being opened.
One end of the locking member 40 located inside the housing 10 may be elastically supported by an elastic member 42.
By elastically supporting one end of the locking member 40 by means of the elastic member 42, the elastic force of the elastic member 42 is applied to the locking member 40 with the locking member 40 in the released state, thereby automatically restoring the locking member 40 to its previous state before the release.
Herein, since the elastic force of the elastic member 42 is smaller than the external force applied to the rotation member 20 and the locking member 40 by the rotation of the handle 300, the elastic force acts only in a state where the external force is not applied to the rotation member 20 and the locking member 40, i.e., when the non-rotated state of the handle 300 is maintained from when the handle 300 is converted from the rotated state to the previous state.
The movable member 60 may include one or more openings 61, the openings 61 engaging some of the gear teeth 22 of the rotating member 20.
By forming the opening 61 on the movable member 60, the rotating member 20 is rotated with some of the gear teeth 22 engaged with the opening 61, and thus the movable member 60 is lowered.
Herein, the upper end of the movable member 60 may be elastically supported by the elastic member 62.
Since the upper end of the movable member 60 may be elastically supported by the elastic member 62, the elastic force of the elastic member 62 is applied to the movable member 60 in a state where the movable member 60 is lowered, thereby automatically restoring the movable member 60 in the lowered state to its previous state.
Here, since the elastic force of the elastic member 62 is smaller than the external force applied to the rotating member 20 and the movable member 60 by the rotation of the handle 300, the elastic force acts only in a state where the external force is not applied to the rotating member 20 and the movable member 60, that is, when the non-rotated state of the handle 300 is maintained from when the handle 300 is converted from the rotated state to the previous state.
In addition, the lower end of the stopper 70 may be elastically supported by an elastic member 71.
By elastically supporting the lower end of the stopper 70 by means of the elastic member 71, the elastic force of the elastic member 71 is applied to the stopper in a state where the locking of the stopper 70 with the locking member 40 is released, thereby automatically restoring the stopper 70 in the lock released state from the locking member 40 to its previous state.
Here, since the elastic force of the elastic member 71 is smaller than the external force applied to the rotation member 20, the movable member 60, and the stopper 70 by the rotation of the handle 300, the elastic force acts only in a state where the external force is not applied to the rotation member 20, the movable member 60, and the stopper 70, that is, when the non-rotation state of the handle 300 is maintained from when the handle 300 is converted from the rotation state to the previous state.
The cover 50 is combined with the housing 10 and closes the inner space of the housing 10.
By closing the inner space of the housing 10 with the cover 50, the rotary member 20, the arm 30, and the locking member 40 are prevented from being separated from the housing 10 from the inner space and damage to the rotary member 20, the arm 30, and the locking member 40 is prevented.
The cover 50 may include an opening 51, and the opening 51 communicates with the through hole 21 provided on the rotary member 20.
By forming the opening 51 provided on the cover 51, the central shaft 310 of the handle 300 is inserted into the through hole 21 via the opening 51, so that the rotation member 20 can be rotated by the rotation of the handle 300.
In addition, the cover 50 may be coupled with the housing 10 by screws (no reference numeral).
By coupling the cover 50 with the housing 10 by means of screws, the cover 50 can be separated from the housing 10 and the coupled state between the cover 50 and the housing 10 can be securely maintained.
Now, the opening of the window sash frame 200 will be described in detail, and the above-described opening assistance device a for a sliding window according to the present invention is applied to the window sash frame 200.
In the present invention, since the housing 10 is installed in the side of the window sash frame 200 adjacent to the inner surface of the window frame 100, the central shaft 310 of the handle 300 disposed at the side of the window sash frame 200 may be inserted into the through hole 21 of the rotation member 20 disposed in the housing 10.
Thus, a user may grasp and rotate the handle 300, thereby rotating the rotation member 20, as exemplarily shown in fig. 6.
Here, a plurality of gear teeth 22 are formed on the outer circumferential surface of the rotating member 20, and some of the gear teeth 22 are engaged with gear teeth 31 formed on the outer circumferential surface of one end of the arm 30 seated in the housing 10.
Therefore, when the arm 30 is rotated by the rotation of the rotating member 20, as exemplarily shown in fig. 7, one end of the arm 30 exposed to the outside of the housing 10 protrudes toward the inner surface of the window frame 100, so that the sash frame 200 is separated from the window frame 100 in the opening direction by a reaction force when the arm 30 is in contact with the window frame 100.
During the process of separating the window sash frame 200 from the window frame 100, when the window sash frame 200 is moved in the opening direction by pushing or pulling the handle 300, the window sash frame 200 may be slid in the lateral direction even with a relatively small force. Accordingly, the window sash frame 200 may be easily opened, as exemplarily shown in fig. 5.
However, in the present invention, since the locking member 40 and the arm 30 are disposed within the housing 10 in a state where the window sash frame 200 is closed and the locking member 40 is locked, that is, in a state where the ring portion 41 of the front end of the locking member 40 is inserted into the striker 120 fixed to the inner surface of the window frame 100, as exemplarily shown in fig. 4, the sliding of the window sash frame 200 in the lateral direction may not be performed, so that the window sash frame 200 may not be opened.
However, in the present invention, some of the gear teeth 22 on the outer circumferential surface of the rotating member 20 are engaged with the gear teeth 31 on the outer circumferential surface of the arm 30, and other gear teeth 22 are engaged with the opening 61 of the movable member 60 disposed within the housing 10, as exemplarily shown in fig. 9.
Accordingly, the movable member 60 is lowered while rotating the arm 30 by the rotation of the rotating member 20, the stopper 70 provided at the lower portion of the movable member 60 is lowered due to the lowering of the movable member 60, as exemplarily shown in fig. 10, and the locking between the stopper 70 and the locking member 40 is released by the lowering of the stopper 70. Then, the locking member 40 may be released from the locked state, as exemplarily shown in fig. 8, and the window sash frame 200 may be smoothly opened without interfering with the locking member 40.
although the opening of the sliding window has been exemplarily described above, the above-described effects can be obtained if the opening assistance device a for a sliding window of the present invention is applied to a hinged door.
As apparent from the above description, the opening assistance device a for a sliding window according to the present invention includes the releasable locking member 40 provided in the housing 10 and the arm 30 protruding toward the inner surface of the window frame 100, and thus has a simple structure as compared to the case where the locking device and the opening device are separately provided, thereby being easily manufactured and installed. In addition, since the release of the locking member 40 and the protrusion of the arm 30 are performed in synchronization by the rotation of the rotating member 20, the opening assisting device a for a sliding window can shorten the time taken to operate the opening device, as compared to a case where the operation of the locking device and the operation of the opening device are performed sequentially.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
