Sliding window handle assembly capable of automatic locking operation and release switching

In one embodiment of the handle assembly 1 of the present invention, the rotating shaft member 40 is inserted into a general locking type locking device (not shown) in which the locker (or lock pin) is locked or unlocked to the striker. It is combined as much as possible, but acts to enable automatic locking or release automatic locking through the user's manipulation of the switch member 50, and can improve durability while facilitating the transmission of the rotational force of the handle (lever) for operation and release of automatic locking. It was derived to have an internal structure.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 7.

Figure 1 is a perspective view of an embodiment of the handle assembly of the present invention, viewed obliquely from the front, and Figure 2 is a perspective view of an embodiment of the handle assembly of the present invention, viewed obliquely from the back. As shown in Figures 1 and 2, in this embodiment, the protruding portion of the rotating shaft member 40 is inserted into the insertion hole (not shown) of the locking device (not shown) to transmit the handle rotation force to the locking device. do. In addition, the handle portion 10 is formed to be long so that the user can easily grip it, and the assembly housing 60, the outer cover 62, and the inner cover 64 are combined at the end, and the switch member is attached to the top of the assembly housing 60. (50) is configured to protrude and operate by pressing it by the user.

Figure 3 is an exploded perspective view showing the components of an embodiment of the handle assembly of the present invention, and Figure 4 is an exploded perspective view showing the second rotating member, the rotating shaft member, and the inner cover separated from the components of an embodiment of the handle assembly of the present invention. , and Figure 5 is a front view of the configurations of one embodiment of the handle assembly of the present invention, when the inner cover is removed and viewed from the front.

As shown in FIG. 3, the handle portion 10 has a first insertion groove 12 formed at one end, and coupling irregularities 12a (convex and convex) are formed along the inner peripheral surface of the first insertion groove 12. One end of the first rotating member 20 is shape-fitted and inserted into the coupling unevenness 12a inside the first insertion groove 12, and the other end is formed with a second insertion groove 24, and the handle portion 10 ) It functions to rotate between the locked position and the open position in response to rotation.

The joint insertion through shape fitting is to maximize the fixation and coupling force, and one end of the first rotating member 20 is engaged in the first insertion groove 12 to prevent it from spinning, so here, shape fitting means. It is a concept that includes opposing parts that are in contact fitting each other in shape rather than completely corresponding and fitting the concave and convex parts.

Here, the locking position means corresponding to the rotational position in which the locking device (not shown) is locked according to the rotation angle of the rotating shaft member 40. In order to achieve automatic locking, an elastic means (not shown) that exerts a repulsive force in the closing direction is added between the first rotating member 20 and the assembly housing 60. In general, the locking position is preferably such that the handle portion 10 is arranged straight up and down.

Conversely, the open position corresponds to the rotational position at which the lock is released from the locking device (not shown) according to the rotation angle of the rotating shaft member 40, and will be a rotational position within a predetermined range rather than a specific position.

The first rotating member 20 and the rotating shaft member 40 are not completely fixedly coupled and have rotational clearance, and the resulting structure and operation method will be described later.

The second rotating member 30 has a through hole 30a penetrating the central portion and is arranged coaxially with the first rotating member 20, and moves between the locked position and the open position in response to the rotation of the handle portion 10. It has the function of rotating or rotating within a limited rotation range of the open position. The second rotating member 30 may rotate in conjunction with the first rotating member 20. However, when the switch member 50, which will be described later, is involved and has a limited rotation range, it may rotate within the open position without being interlocked with the first rotation member 20.

The rotating shaft member 40 has one end inserted into the second insertion groove 24 through the through hole 30a and the other end inserted into the locking device. Since it transmits strong force, it would be preferable to construct it from a metal material rather than an injection molded material. In this rotating shaft member 40, one end (or part) inserted into the through hole 30a and the second insertion groove 24 has a cross-sectional area larger than the other end (or part in the opposite direction) inserted into the locking device. It may have been formed to be larger. This configuration is desirable for transmitting strong torque in response to the strong rotational force generated in the handle portion 10 and is advantageous for switching operations by intervention of the switch member 50, which will be described later.

The switch member 50 has a locking protrusion 52 formed on one side and slides in one direction so that the second rotating member 30 is caught by the locking protruding member 52, or slides to the other side so that the second rotating member 30 is caught. It is configured to break away from the jaw (52). The switch member 50 can relatively slide according to the guide of the protrusion of the assembly housing 60, and a restoration action is also performed when the user presses the external protrusion through the spring 54.

The assembly housing 60 serves to accommodate the first rotating member 20, the second rotating member 30, a part of the rotating shaft member 40, and a part of the switch member 50, and in addition, as described above, it is self-locking. For this purpose, it functions to fix the self-locking spring between the first rotating member 20 and also performs a sliding guide function of the switch member 50.

Meanwhile, the first rotating member 20 is further formed with a pair of rotating guide protrusions (26a, 26b) in the direction of the second rotating member 30, and the second rotating member 30 has a pair of guide protrusions ( A pair of rotation guide holes 36a and 36b into which 26a and 26b can be respectively inserted are further formed. A pair of rotation guide protrusions (26a, 26b) and a pair of rotation guide holes (36a, 36b) interconnect the first rotation member 20 and the second rotation member 30 within a predetermined range to interlock rotation. It works like this.

In particular, the second rotating member 30 is configured to block the rotational force of the first extended portion 32 and the first rotating member 20, which are formed with a stopper protrusion 32a that is caught by the locking protrusion 52 and limits the rotation range. 2 It is preferable that a second extension 34 is formed to which a torsion spring 35 is added to transmit the power to the rotating member 30. And the second expansion part 34 has a concave groove structure 34a on which the torsion spring 35 can be mounted, and a mounting hook for mounting the torsion spring 35 is further formed inside the concave groove structure 34a. , the torsion spring 35 may be disposed between any one of the pair of guide protrusions 26a and 26b and the inner wall of the concave groove structure 34a.

Figure 6 is a perspective view showing the operation situation between the switch member and the second rotating member among the configurations of one embodiment of the handle assembly of the present invention, and Figure 7 is a perspective view of the cover and the second rotation member among the configurations of one embodiment of the handle assembly of the present inventors. This is a front view shown to explain the rotational relationship between the rotating shaft member and the first rotating member with the rotating member removed. Hereinafter, the operational relationship of this embodiment will be described in detail with reference to FIGS. 6 and 7.

The first rotating member 20 forms a locking convexity and convexity 24a on the inner peripheral surface of the second insertion groove 24, and a corner of the outer peripheral surface of the rotating shaft member 40 is caught by the convex portion of the locking unevenness 24a. It is preferable that the concave portion of the locking unevenness 24a is formed to have a rotation clearance A1 that can rotate. The resulting operating states are as follows.

As shown in Figure 6, the self-locking rotation range is indicated by R1. Among the sliding directions S1 of the switch member 50, sliding in the downward direction serves to enable rotation of the self-locking rotation range R1. As a result, the rotation of the rotating shaft member 40 tightly engaged with the second rotating member 30 occurs simultaneously, and the rotating shaft member 40 rotates beyond the rotational gap A1, thereby causing the corner 41 of the rotating shaft member 40. is caught by the catching unevenness 24a so that the first rotating member 20 is interlocked and can be rotated to both the open position and the locked position.

Conversely, the open position rotation range is indicated as R2. The upward sliding of the switch member 50 in the sliding direction S1 acts to allow the second rotating member 30 to rotate within the rotation range R2 of the automatic unlocking position, that is, the open position. As a result, the rotation of the rotating shaft member 40 tightly engaged with the second rotating member 30 occurs simultaneously, but it can only rotate in the open position, and the rotating shaft member 40 rotates only within the rotational gap A1, thereby causing the first rotation. Even though the engaging unevenness 24a of the member 20 transmits force to the corner 41 of the rotating shaft member 40, rotation to the locked position is no longer restricted. That is, the first rotating member 20 is not interlocked with the second rotating member 30 and the rotating shaft member 40 and can be rotated only in the open position.

Although embodiments of the present invention have been described with reference to the attached drawings, the technical configuration of the present invention described above can be easily modified by those skilled in the art in the technical field to which the present invention belongs in other specific forms without changing the technical idea or essential features of the present invention. You will be able to understand that this can be implemented. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive. In addition, the scope of the present invention is indicated by the claims described later rather than the detailed description above.
