Description

{Non-locking moving type door handle for windows}

[0001] The present invention relates to a lock handle for a window, and more particularly, to a lock handle for a window, which comprises a button shaft portion which is locked to the striker, thereby forming a switch portion, and sliding portions of the button portion are engaged in an inclinable manner The present invention relates to a handle for a window handle that ensures smooth operation by simplifying the operation structure while eliminating the problem of breakage caused by vertical collision during operation.

In general, the locking device of a window, particularly a sliding window, in a window is roughly divided into a strike, a hook which acts on the strike and a hook which moves the hook by attaching the hook.

Among them, the handle is distinguished by a rotary handle, which is a type of opening and closing the sliding window by rotating the handle, and a grip handle by which the sliding window is opened and closed by rotating the hook connected to the end by pressing the handle by hand.

However, in the case of a rotary handle, since it has a long bar shape, there is a large risk of injury due to a collision due to collision or interference.

Therefore, a grip type handle having a beautiful appearance is preferred because it is not only simple in structure that operates by pressing only the handle, but also is not exposed to the outside in a form in which the lock units are built-in.

Prior art related to such a handle is disclosed in a number of patent applications 1195836, 1195842, 0999403, and 1641021, among others.

Among these prior arts, in particular, in the case of Japanese Patent No. 1641021, a pair of lock hooks is placed at the top dead center position in the window open state, and when the lock button and the striker are touched, The lock hook of the top dead center position moves to the bottom dead center position and is seated in the square hole of the striker so that the window can be closed smoothly and the window can be opened easily by applying a force to the lever toward the opening direction of the window It is highly utilized.

However, the button shaft portion constituting the lock button disclosed in Japanese Patent No. 1641021 is constructed such that the button shaft portion is vertically collided with the striker so that the button shaft portion is vertically pressed against the striker, It has limitations that are easy.

If the striker is damaged during use, it is not necessary to replace only the part, but the entire locking device must be replaced, resulting in an increase in labor and material costs due to equipment and rework, a decrease in operational stability, and increased consumer complaints.

In addition, the structure of the shaft body for driving the lock button is complicated, which is disadvantageous in securing the operation of the operation source. That is, it is structurally complicated.

Prior to the description of the specific construction and operation of the present invention, the basic concept of the present invention is similar to that of the registered patent No. 1641021 which has been described in the prior art. However, in order to solve the problems of the above-mentioned patent, in particular, the structure of the lock hook, the shaft body, the lock button, and the bottom plate for assembling them has been improved. Reference will be made to the above-identified patents.

In other words, the present invention mainly focuses on emphasizing the difference between the two.

As shown in FIG. 1, the lock handle for a window according to the present invention includes a lever 200 to be operated by a user, a housing 200 to which components including the lever 100 are assembled, And a lock hook spring (410) which is moved by the shaft body (300) and has a resilient returning force. The lock body (300) is rotatably moved for locking and unlocking, (500) including a lock button spring (SPR) that locks or unlocks the lock hook (400), and provides an elastic force in a direction orthogonal to the flow direction of the lock hook (400) And a striker 700 used to maintain the locked state, and their basic configuration and operation are as described in the above-mentioned patent.

1 and 2, the shaft body 300 is provided with a shaft block base 312 in the form of a square block at both ends thereof, and the shaft base 312 includes a bar-shaped operation shaft 310, And a coupling shaft 320 which is fitted on the lever 100 and is rotatable in a range of 30 ° together with the lever 100 on the shaft base 312.

In addition, a pair of operating pieces 330 protruding from the outer circumferential surface of the operation shaft 310 are provided integrally with each other.

A lock-hook spring groove 420 is formed on both sides of the upper surface of the lock-hook 400 so that one end of the lock- A pair of hook shafts (430) spaced apart from each other protrude from a lower surface of the lock hook (400) at positions that do not interfere with the operation piece (330).

At this time, the hook shaft 430 is locked or unlocked while being inserted into the lock groove 710 formed on both sides of the striker 700.

In addition, a lock button flow groove 440 is formed on one side of the lock hook 400, more precisely on the side facing the lever 100, in a generally '⊃' shape, The locking block 522 is moved while the lock hook 400 is inserted and fixed or the locking state is released and the lock is released.

3, a shaft body 300 is mounted on the bottom plate 600 and a lock hook chamber 610 is formed on one side of the bottom plate 600 to insert the lock hook 400, A lock hook hole 620 is formed in the bottom surface of the lock hook chamber 610 so that the lock hook 430 is inserted through the lock hook hole 620.

In addition, a lock button guide 630 protruding upward is formed at the center of the length of the lock-hook chamber 610, and has a flat surface of a '⊃' shape.

In this case, the lock button guide 630 is kept open at one side, and slide grooves 632 having a predetermined depth are formed on both sides of the lock button guide 630. A lock button 500 is inserted into the lock button guide 630 .

In addition, the lock button 500 has a vertically segmented structure as shown in FIG.

That is, the lock button 500 is divided into a contact member 510 to be in contact with the striker 700 and a lock member 520 to lock or unlock the lock hook 400.

The contact member 510 includes a rod portion 512 having an inclinable surface IC so that the contact member 510 can ride on the striker 700 when the striker 700 contacts the rod portion 512, A triangular block 514 having an oblique surface integrally formed at an upper end of the triangular block 514 and a protruding piece 516 protruding in an inverted triangular shape at the center of the oblique width of the triangular block 514.

The locking member 520 includes a locking block 522 having a plurality of locking troughs TR formed on one side thereof and a guide protruding from both sides of the locking block 522 and guided by the slide groove 632 A pair of fitting pieces 526 protruding from the lower end surface of the lock block 522 and fitted in the protruding piece 516 and having an inclination corresponding to the inclinable surface IC, A spring groove 526 formed on a surface opposite to the surface on which the latching protrusion TR is formed, and a lock button spring SPR fitted in the spring groove 526.

Particularly, the fitting piece 526 has an inclined surface length smaller than the length of the inclinable surface IC, preferably about 1/2, so that the inclined surface of the triangular block 514 It is preferable that the inclined surface slides down or up.

In the case of the striker 700, unlike the prior art, the present invention includes only a pair of the locking grooves 710, but it is not necessary to include a separate groove A clean appearance can be provided.

The present invention having such a configuration has the following operational relationship.

First, as shown in FIG. 5, in a state in which the window is opened, the rod portion 512 of the lock button 500 does not collide with the striker 700.

3) by the pushing force of the lock hook spring 410 (see FIG. 1), and thus the lock button 400 is in a state of being pressed downward in the lock hook chamber 610 Since the lock block 522 is in the fully downward state and the lock butt spring SPR is pushing the lock block 522 laterally, the latching jaw TR of the lock block 522 will not lock the lock hook 400 And the lock hook 400 remains in a stopped state without moving.

At this time, the rod portion 512 is formed to be longer than the hook shaft 430 of the lock hook 400 so that the rod portion 512 can contact the striker 700, and the hook shaft 430 is held in the lock block 522 The striker 700 is in a state of being able to ride over.

6, the rod portion 512 first comes into contact with the striker 700, and at the moment when the rod portion 512 comes into contact with the rod portion 512, the inclinable surface IC, which is the lower end inclined surface of the rod portion 512, The fitting piece 526 of the locking block 522 compresses the lock button spring SPR while moving downward along the inclined surface of the triangular block 514 and at the same time the locking block 522 is moved in the upward direction, The lock hook 400 is released from the lock hook 400 by the resilient return force of the lock hook spring 410 pushing the lock hook 400 at the moment when the clamping force TR is released, The hook shaft 430 is inserted into the locking groove 710 of the striker 700 and is locked.

In this state, pull the lever 100 (see FIG. 1) to open the window.

7 and 8, the operation member 330 lifts the lock hook 400 as the operation shaft 310 rotates.

8, the hook shaft 430 is separated from the locking groove 710 of the striker 700. When the window shaft is moved out of the striker 700 in this state, when the striker 700 leaves the striker 700, The pushing force of the lock button spring SPR causes the lock block 522 to approach the lock hook 400 and move in the opposite direction to the lock operation described above so that the lock jaw TR is locked to the lock hook 400) to fix.

Therefore, even when the lever 100 is pulled by the user, since the lock hook 400 is fixed to the latching jaw TR, the state at the time of chuck opening is maintained as shown in Fig. That is, the state shown in FIG. 5 is obtained.

Then, when closing again, the process described above is repeatedly performed and locked.

As described above, according to the present invention, the structure of the lock button is improved so that it can be flowed in an unclined manner with a divided dual structure, thereby achieving the ease of assembly through the operation stability, the original activity and the structural simplification. In the present invention, it is possible to obtain the advantage of eliminating the problem of collapsing while colliding with each other.
