Description

Keeper for sliding windows equipped with an opening assistance device {Lock device for sliding window with easy door opening}

The present invention allows the rotor to release the hook when the lever handle is turned, while also interlocking the push rod that pushes the window frame with a short time gap, so that when opening a closed window, it is opened smoothly without using force. It relates to a keeper for slide windows equipped with an opening auxiliary mechanism that enables increased assembly, reduced manpower and assembly time, and maximized durability by being composed of a minimum number of parts.

Various windows are installed on the inside and outside of various buildings for the purpose of controlling access and lighting.

At this time, windows are classified into sliding, hinged, or fixed types depending on the opening and closing method, and sliding windows, that is, sliding windows, constitute the main medium to large-sized windows installed in living rooms and verandas of houses.

Such a sliding window is opened and closed by sliding laterally in the horizontal direction as the roller at the bottom of the window frame rotates along the rail of the window frame when the handle provided on the window frame is held and pushed or pulled to one side.

Meanwhile, in the case of recent mid-to-large sliding windows, thicker glass or double- or triple-layer glass is applied to the window frame compared to before to improve insulation performance, so the weight of the window is considerable, and the window frame and frame frame are used to block noise and outside air. Since an airtight means such as mohair was applied in between, the moment of opening the window that had been closed by the airtight means required the most effort and was inevitably inconvenient.

Accordingly, Republic of Korea Publication No. 20-2010-0012532 (publication date: December 17, 2010) (hereinafter referred to as ‘Patent Document 1’) has been proposed as a technology to solve the above-mentioned problems.

Patent Document 1 is an opening device in which a rack for an opening device is formed on a slide bar on which a rack coupled with a pinion and gear coupled to a handle that drives a locking device is formed, and the door frame falls from the door frame in front of the rack for the opening device. The opening device includes a body fixed to the door frame while being inserted into the rail groove, rotatably assembled to the body with an arm pin, and a pinion protrusion engaged with a rack for the opening device formed on the slide bar. An arm formed in several pieces, a roller assembled at the tip of the arm, and a leaf spring installed in contact with the vertical part of the arm while fixed to the body to elastically support the arm so that it is located inside the body. It consists of

In Patent Document 1 having the above configuration, when the handle provided on the door frame is rotated, the arm rotates together with the handle to separate the door frame from the door frame, so that medium to large sliding windows can be easily opened.

However, Patent Document 1 has a complex structure as it is provided with a locking device and an opening device driven by a handle, so not only is it cumbersome to manufacture and install, but the opening device is operated after the locking device is released first. Therefore, there was a problem that it took a considerable amount of time to operate the opening device.

Meanwhile, as an invention to solve the above problems of Patent Document 1, Patent Registration No. 10-2052529 (Patent Document 2), Patent Registration No. 10-2024764 (Patent Document 3), and Patent Registration No. 10-2002311 ( Patent Document 4), and Patent Publication No. 10-2019-0117420 (Patent Document 5).

Patent Documents 2 to 5 described above install an arm that directly or indirectly interlocks with a lever handle at a predetermined position inside the locking device, and install a roller at the tip of the arm.

However, in Patent Documents 2 to 5 described above, the arm that pushes the door frame while rotating in the opposite direction by the lever handle is opened by rotating in a pinion or link system interlocking with the rotor, so the number of parts is large, which makes assembly cumbersome. There is a problem that the manufacturing cost inevitably increases due to excessive assembly time and manpower.

In addition, in order to operate the arm, a separate link or pinion had to be installed between the rotor and the arm, which inevitably increases the volume and weight of the keeper.

The present invention was invented to solve the above-described conventional problems. In particular, the rotor linked with the lever operates the push arm that pushes the window frame together with the hook, but when the rotor rotates, the hook is first released, Next, the purpose of the invention is to provide a keeper for a slide window that allows the push arm to push the window frame and the reaction allows the window to be easily opened.

In addition, the present invention is configured so that the rotor can directly interlock with the push arm that induces easy open, so that a separate intermediary part for operating the push arm is unnecessary, and thus, while having an easy open function, The purpose of the invention is to provide a keeper for sliding windows that maximizes cost savings by reducing the number of parts.

Inside the keeper housing (10), a push protrusion (11) is rotated by the lever handle (H) and has an inclined surface (11a) that frictionally acts on the inclined surface (21) of the tip of the slider (2) on the upper side, and a push arm ( A rotor (1) consisting of an interlocking part (12) connected to 4) and a hinge (h);

It is provided on the upper part of the rotor (1) and is provided with a locking protrusion (22) on one upper side for locking or unlocking the hook (3), and is moved up and down by the push protrusion (11) and spring (s) to lock the hook (3). Slider (2) for setting or unlocking;

A hook (3) that is always in the unlocked position by a torsion spring (not shown) and is locked or unlocked by the organic action of the striker (5) and the slider (2) when opening or closing a window or door;

A hinge (h) is assembled to the lower part of the rotor (1) and a push arm (4) is formed by extending the operating shaft (42) with a long hole (43) in the hinge portion (41), so that the rotor (1) It is characterized by interlocking the operation units 42 to enable easy and effortless opening of the window or door.

Meanwhile, the linkage part 12 of the rotor 1 pushes the operating shaft 42 of the push arm 4 so that the push arm 4 pushes the window frame wf so that no force is applied when opening the window, and the rotor ( When 1) is restored, the push arm 4 is also restored by the restoring force of the torsion spring (not shown).

In the present invention configured in this way, when the lever handle (H) is turned, the rotor (1) rotates to raise the slider (2) to release the hook (3) and at the same time push the push arm (4). At this time, the slider (2) ), even if it rises only slightly, the locking protrusion 22 that controls the hook 3 is separated from the hook 3, and the hook 3 is momentarily released by the restoring force of the torsion spring, and then is attached to the lower part of the rotor 1. The provided linkage part 12 presses the operating rod 42 integrated with the push arm 4, so that the push arm 4 pushes the window frame wf so that the window can be opened easily without difficulty. As a result, the release of the hook 3 and the easy opening of the window can be accurately performed with a narrow difference.

Therefore, the present invention is very convenient to use because it requires no force when opening a window or door, and reliability is maximized by making the opening stable and accurate, and the rotor (1) is configured to directly push the push arm (4).

The present invention relates to a window keeper (100) that is installed embedded in a window and is easily released by a lever handle (H). In the process of rotating the lever handle (H) to open a closed window (w), the striker first The hook (3) hanging on (5) is released, and then the push arm (4) pushes the window frame (wf) just in the nick of time, and the reaction opens the window. In particular, the parts are simplified. The purpose is to provide a keeper for slide windows with an opening auxiliary mechanism that simplifies the configuration to maximize assembly, thereby reducing manufacturing costs and further improving reliability, which will be described in more detail below according to the attached drawings. If you do so, it is as follows.

The accompanying drawings Figures 1 to 3 are an embodiment of the present invention, Figure 1 is an example of a keeper in an assembled state showing a locked state, and Figure 2 shows a state in which the window is pushed out and the push arm pushes the window frame to open it. This is an example of a keeper shown, and Figure 3 is an example of an enlarged main part.

As shown in Figures 1 to 3, the present invention is configured to assemble the rotor (1), slider (2), hook (3), and push arm (4) inside the keeper housing (10) to interlock with each other.

The rotor (1) has a shaft hole (13) formed so that the square shaft of the lever handle (H) can be inserted and rotated, and the upper side of the shaft hole (13) has an inclined surface (11a) for pushing the slider (2). A protrusion 11 and an interlocking portion 12 that causes the operation shaft 42 of the push arm 4 to appear and slide are formed integrally at the lower portion.

The linkage portion 12 is connected to the operating shaft 42 of the push arm 4 and acts on the inner side to directly raise or lower the push arm 4. The important point here is that the push arm 4 The structure is significantly simplified by constructing the interlocking part 12, which pushes the rotor, integrally with the rotor 1.

Therefore, in the present invention, the linkage portion 12 of the rotor 1 is connected to the push arm 4 without any separate parts or components intervening between the push arm 4 that pushes the window frame wf and the rotor 1. The rotor (1) is connected to the extended operating shaft (42) and the hinge (h) to directly rotate the push arm (4), thereby reducing parts and simplifying the configuration, further reducing costs. The effect can also be maximized.

On the other hand, the push arm 4, which is pushed by the linking part 12 of the rotor 1, is within the space L between the arm support part a of the keeper housing 10 and the window frame wf. ), so the hook (3) can be released stably because it is in an idle state in which the window frame (wf) cannot be pushed out, and the push arm (4) pushes the window frame (wf) immediately after the hook (3) is released. Therefore, the window or door is opened by the reaction, so not only does it require no force at all when opening the window or door, but it can also be opened smoothly.

In addition, the slider (2) has an inclined surface ( 21) is provided, and a spring (s) is interposed at the bottom, so that the slider (2) is always maintained in an elevated state by the restoring force of the spring (s).

In addition, a locking protrusion 22 is formed on the outer side of the lower part of the slider 2, so that when the window or door is closed, the hook 3 touches the striker 2 and is pushed. At this time, the slider 2 is connected to the spring s. ) is raised by the restoring force, and the locking protrusion 22 controls the hook 3 to maintain the locked state.

When you want to open a window or door, rotate the rotor (1) with the lever handle (H) so that the push protrusion (11) raises the slider (2), and the locking protrusion (22) that controls the hook (3) moves into the hook ( By being separated from 3), the hook 3 is released by the restoring force of the torsion spring (not shown), and at this time, the linkage part 12 formed integrally with the rotor 1 rotates at a predetermined angle and moves the push arm. The operating rod (42) of (4) is pressed, and the push arm (4) pushes the window frame (wf) around the hinge (h).

The keeper 100 for windows of the present invention configured as above is installed embedded in the window case (w) of the slide window, and the striker 5 is installed on the window frame (wf) to correspond to the keeper 100, and the window (w) Assembly is performed by inserting the square shaft of the lever handle (H) into the shaft hole (13) of the rotor (1) installed on the keeper (100) through the outside.

In this assembled state, when the lever handle (H) is turned in the direction of opening the window or door, the push projection (11) of the rotor (1), which rotates together with the lever handle (H), forcibly pushes the slider (2) frame. At the moment of raising, the hook (3) is released by the restoring force of the torsion spring, and the linkage part (12) of the rotor (1) presses the operating member (42) of the push arm (4), causing the push arm (4) to move into the window frame. By pushing (wf), the window or door can be opened by the reaction, which does not require much force when opening the window or door, allowing it to be opened smoothly and conveniently.

Figures 4 to 6 show another embodiment of the present invention, in which the operation section 42 of the push arm 4 and the interlocking portion 12 of the rotor 1 are separated, and the push arm 4 ) is configured to elastically return to its original position by a torsion spring (not shown), which means that when the window is opened by turning the lever handle (H), the push arm (4) is naturally moved by the rotor (1). By pushing the window frame (wf), no force is required to open the window, and when the rotor (1) is restored, the push arm (4) is also restored by the restoring force of the torsion spring (not shown).

Meanwhile, the present invention may further provide a roller at the tip of the push arm 4, and in this case, friction with the window frame (wf) is minimized when opening the window, making it possible to open the window more smoothly.
