Description

Handle with lock indication function}

The present invention relates to a handle having a lock indication function in conjunction with a locking device installed on a window. More specifically, the present invention relates to a handle that is configured to release the fixed state of the lever only when the window is in close contact with the window frame and is in a closed state. , It relates to a handle that is configured to display the operating status of the locking device installed on the window to the outside during the process, allowing the user to easily check whether the window is locked.

In general, handles on windows serve to facilitate the user's process of opening and closing the window, and also serve to prevent the user's handprints from being left on the glass during the process of opening and closing the window.

Therefore, most windows are equipped with fixed handles or automatic handles, and some may be equipped with semi-automatic handles instead of automatic handles.

Among these, the automatic handle and semi-automatic handle are installed in conjunction with the locking device installed on the window. When rotated by the user, the lock device is converted to the open state, and when rotated in the opposite direction, the lock device is returned to the locked state. It will be converted.

In other words, the user can determine whether the window is locked based on the position of the window and the rotation state of the lever provided on the automatic handle and semi-automatic handle, but in reality, the window is judged to be locked when it is not locked, or when it is locked when it is locked. Because there are cases where the opposite judgment is made, many users are going through the trouble of checking themselves.

Therefore, it can be said that there is a need for a method to reliably check whether the window is locked in a simpler way. In relation to this, the “Handle assembly for windows and doors equipped with an open/closed indicator” in Korean Patent Publication No. 10-2003113 and Inventions such as “Automatic locking device for sliding windows with lock confirmation function” in Republic of Korea Patent Publication No. 10-2183385 have been proposed and disclosed.

First, in the Korean Patent Publication No. 10-2003113, “Handle assembly for windows and doors equipped with an open/close indicator”, the handle that opens and closes the window is linked when an automatic locking device is driven on the outside of the handle to indicate ‘open’ and ‘locked’. An invention has been proposed and disclosed regarding a device that allows the user to easily visually check the open or locked state of a window or door by providing a display unit that displays one of the 'Close' marks.

In addition, in the above-mentioned Korean Patent Publication No. 10-2183385, “Automatic locking device for sliding windows with lock confirmation function,” the locker of the automatic locking assembly is displayed as locked or opened only when the locker of the automatic locking assembly is securely locked or unlocked with the striker of the window frame. An invention regarding a device that enables display has been proposed and disclosed.

In this way, it can be fully expected that by using the devices proposed by the above-mentioned inventions, the user will be able to easily and reliably check whether the window is locked.

However, since the above-mentioned devices are patented, there are problems in the view of others skilled in the art that restrictions on use or additional costs are incurred due to use, so from the point of view of other people skilled in the art, It can be said that the development of a new semi-automatic handle that can be freely used with rights is necessary.

In addition, as shown in FIG. 1, a straight cut groove is formed in the main body 100a corresponding to the position where the slider 130 is installed inside, and a front cover ( A confirmation hole 102 is formed on one side of 100b) so that the display unit 131 provided on one side of the slider 130 can be checked from the outside.

At this time, the confirmation hole 102 must be formed on one side of the front cover 100b in a shape with a diameter of 50% or less compared to the length of the incision groove, and the shape of the key hole so that any user can easily recognize its purpose. It may be formed, but this is not necessarily the case.

Accordingly, only part of the display unit 131 provided on one side of the slider 130 can be checked from the outside of the case 100 through the confirmation hole 102, and as a result, the locking device 200 installed on the window Only one of the locked or open states can be displayed to the outside.

In addition, the lever 110 is a component used as a handle when a user opens and closes a window, and as shown in FIG. 3, when installed on the outside of the case 100, it rotates by an external force and is installed on the window. Allow the locking device 200 to operate.

That is, the lever 110 is installed to interlock with the locking device 200 installed on the window and door through the case 100, and is locked by the locking device 200 after the external force applied by the user disappears in the rotated state. It automatically rotates in the opposite direction and returns to its original state.

Next, the cam mechanism 120 is a component to which the axis of the lever 110 is fastened, and rotates with the lever 110 when installed inside the case 100, and slider 130 installed together inside the case 100 ) to move it.

More specifically, as shown in FIG. 4, the cam mechanism 120 has an upper portion of the cam mechanism 122 including bidirectional inclined protrusions 121 protruding laterally, and a cylindrical body 123. It is characterized in that a protrusion-shaped catch 124 is formed to protrude to another side from the outer peripheral surface of the.

In addition, the cam mechanism 120 is characterized in that an insertion hole 125 into which the axis of the lever 110 is fitted is formed to penetrate the clamp 122 and the body 123, as shown in FIGS. 5A and 5A and FIG. As shown in 5b, the lever 110 is fastened in a rotatable state installed inside the case 100 and then rotates together with the lever 110.

At this time, as shown in FIG. 2, the inside of the case 100 has a curved surface corresponding to the outer peripheral surface of the body 123 of the cam mechanism 120 so that the entire case 100 can be used for installation of the cam mechanism 120. A plurality of locking protrusions (103) are provided or formed around the through hole (101), and among them, one of the locking protrusions (103) is located below the other locking protrusions (103) in the installation form of the present invention. ) The rotation angle of the cam mechanism 120 may be limited.

In addition, as shown in FIGS. 2, 5A, and 5B, inside the case 100, a ⊥-shaped or straight-shaped fixture 104 is provided in the through hole 101 based on the installation form of the present invention. By being provided below or protruding, the rotation angle of the cam mechanism 120 can be limited.

That is, the cam mechanism 120 is in a form in which the protrusion 121 of the fastener 122 is located upward and the latching member 124 is located downward, based on the shape in which the straight case 100 is installed perpendicularly to the window. It is installed inside the case 100, and the latch 124 is rotated by the lever 110 until it touches the latch protrusion 103, or in the opposite direction until the latch 124 touches the fastener 104. can be rotated.

At this time, in the embodiment shown in FIGS. 5A and 5B, the latch 124 of the cam mechanism 120 can rotate only in section a shown in FIG. 2, but the lever 110 for opening the window ), when the direction of rotation must be formed in the opposite direction, a cam mechanism 120 in which the protrusion 121 and the catch 124 are formed in different positions and a slider 130 of a corresponding shape can be used. In this case, the catch 124 can be used. (124) can rotate only in section b shown in Figure 2.

In addition, the slider 130 is a component for locking indication that operates in conjunction with the cam mechanism 120, and can slide a predetermined distance in both directions in response to the customized internal structure formed in the case 100, but can slide in other directions. It is installed in a way that movement to is restricted.

That is, the slider 130 is configured to move up and down only in the vertical direction within the case 100 based on the installation form of the present invention, and as shown in FIGS. 5A and 5B, a rotating cam mechanism In a state where it is pushed vertically upward by 120, return to its original state is limited by the stopper 140 located below.

More specifically, as shown in FIG. 6, the slider 130 has a spring S1 installed inside and an inner portion 132 provided with a display portion 131 on the outside has the shape of a groove with an opening. It is characterized in that it is formed at one end, and an open hole 133 having an opening in the opposite direction is formed at the other end.

In addition, the slider 130 is characterized in that the insert 122 of the cam mechanism 120 forms a clearance space and the internal hole 134 is formed to penetrate the upper and lower ends, and the case 100 ) is configured to move upwardly by being pushed by the protrusion 121 when the cam mechanism 120 rotates while being installed in a vertically movable form inside the longitudinal direction.

That is, as shown in FIGS. 5A and 5B, the cam mechanism 120 is located in the inner hole 134 of the slider 130 in the form of forming a clearance space downward, and in this state, the display unit 131 ) is displayed externally through the confirmation hole 102 of the case 100.

At this time, the internal hole 134 has an internal structure 134a corresponding to the shape of the protrusion 121 constituting the cam mechanism 120, which is additionally formed in a diagonal direction on one side, the upper side, based on the longitudinal direction. It is configured so that the upper end of the cam mechanism 120 based on the installation type can be positioned in close contact, and the lower end of the cam mechanism 120 can be positioned in close contact even when the slider 130 is moved upward. .

Therefore, when the cam mechanism 120 rotates together with the lever 110 in the process of opening the window, the protrusion 121 swings, thereby pushing up the inner surface of the inner entrance hole 134. As a result, the slider 130 moves upward so that the open indication of the display unit 131 is displayed to the outside through the confirmation hole 102 of the case 100.

That is, the display unit 131 is configured to be divided into a closed display and an open display, of which the closed display is installed to correspond to the confirmation hole 102 of the case 100, and the slider ( As the position of 130) changes, the open indication may correspond to the confirmation hole 102.

At this time, the open mark and the close mark constituting the display unit 131 may be distinguished by clearly contrasting colors to enable clear identification by the user's naked eye, but this is not necessarily the case.

Meanwhile, when the slider 130 moves upward, the spring S1 installed in the inner part 132 is compressed by the internal structure of the case 100, thereby forming a restoring force for returning the slider 130 to its original state. It will happen.

However, the position of the stopper 140 installed below occurs simultaneously with the upward movement of the slider 130, and as a result, the original state of the slider 130 is maintained until the locking device 200 installed on the window is fastened to the striker. Return to work is limited.

That is, when the window is open, the open indication of the slider 130 is displayed externally, and then the locking device 200 is fastened to the striker, and when the window is closed, the slider 130 is locked. This configuration returns to the original state and changes to the closed display.

However, since the rotation of the cam mechanism 120 to its original state by the upwardly moving slider 130 is not restricted, as soon as the user's external force applied to the lever for the purpose of opening the window is extinguished, the lever 110 and the cam The mechanism 120 rotates in the opposite direction and returns to its original state.

In addition, the stopper 140 is a component for the purpose of controlling the movement of the slider 130, and is installed in a horizontally movable form inside the case 100 using a spring S2 to move the slider 130 according to the position. (130) allows or restricts movement.

More specifically, as shown in FIGS. 7A and 7B, the stopper 140 has a locking portion 141 installed in a horizontally movable form inside the case 100 using a spring S2 and an inclined surface. This formed end is characterized in that it is configured in a form including a straight interlocking bar 142 installed in a form that enters the inside of the locking device 200 installed on the window.

At this time, as shown in FIG. 7A, the stopper 140 rotates the lever 110 and the cam mechanism 120 in a state in which the spring S2 is compressed but the movement is restricted by the slider 130. When the upward movement of the slider 130 occurs according to , it moves using the restoring force of the spring S2.

That is, as shown in FIG. 7B, the locking portion 141 constituting the stopper 140 moves to a position corresponding to the opening hole 133 before the slider 130 rises, and as a result, the slider 130 ) limits the return to its original state by downward movement.

At this time, the open hole 133 is configured to allow the interlocking bar 142 constituting the stopper 140 to pass through while restricting the passage of the catching portion 141, and at the same time, the distal end including the opening is external. By being configured in a form that extends toward , the side part of the stopper 140 can be held using the opening when the upward movement of the slider 130 occurs.

And as the position of the stopper 140 moves, the straight interlocking bar 142 enters deeper into the interior of the locking device 200 installed on the window, thereby pushing the push bar 150 installed in a slideable form therein. Allow it to protrude to the outside.

At this time, the push bar 150 is a component installed in the locking device 200, and is installed in a form that can be entered and exited from the locking device 200 with one end formed in an inclined structure corresponding to the inclined surface of the interlocking bar 142. It is linked with the stopper 140.

That is, as shown in FIGS. 8A and 8B, the push bar 150 protrudes out of the locking device 200 by the stopper 140 in the process of opening the window, and when it is closed again, By being pushed by the window frame and entering the inside of the locking device 200, the position of the stopper 140 is returned to its original state.

Accordingly, the stopper 140 is moved again in the form shown in FIG. 7A, which causes the slider 130 to move downward and the closed indication of the display unit 131 is displayed externally.
