Description

Locking / releasing device of anti-insect screen of roller type}

The present invention relates to a roller-type insect screen used to be mounted on various windows, more specifically to the locking handle in the locking mechanism in the guide rail in the lower handle of the insect screen to move up and down along the vertical guide rail or locked Inserted to both sides, but the locking key is to be released from both sides at the same time according to the downward pressing force acting on the handle by the heart cam locking means to be able to lock and release the deployed insect screen conveniently and efficiently. .

In general, window screens of various buildings are provided with a screen for preventing the entry of bees or foreign substances into the room from the outside.

In particular, in recent years, as the insect repellent screen is wound in a roller form in the housing, the convenience of use is further improved. Such a roller screen retracts the upper housing and the lower chassis member by both vertical guide rails. It is connected to form a frame, and the inside of the housing is inserted into the shaft rod having a spring winding means to form the front end of the insect screen to the shaft rod, and fixed to the lower end of the insect screen so that the user can be gripped by hand However, the handle is formed with a locking and releasing means to be coupled or separated with the lower end of the guide rail.

Therefore, when the grip screen is pulled to pull the screen to the lower side of the housing while the shaft is rotated while the screen is applied while applying the spring compression force to the winding means, the screen is developed by engaging and fixing the handle to the lower end of the guide rail Insect screen is maintained as it is, and if you want to wind the insect screen from the guide rail when the handle is pulled out by the restoring force of the spring winding means in the compressed state the insect screen is automatically wound on the shaft in the housing, This will open the door and remove the screen.

In addition, the locking and releasing means configured in the handle bar as described above has been applied in various forms, the Republic of Korea Utility Model Publication No. 20-2009-0009652 (published September 24, 2009) or As disclosed in Korean Patent Publication No. 10-2011-0026835 (published March 16, 2011), the locking key has a rod-shaped sliding sideways from the inside of the handle and a spring button for flowing the locking key, and the locking As the locking mouth having a locking groove is formed inside the lower end of the guide rail corresponding to the end of the key, the locking key flows in the lateral direction through the operating force of the spring button to which the artificial force is applied, thereby engaging or locking the locking door. It has a form that separates and leaves.

However, the locking and releasing structure of the handle by the spring button, which is a conventional component as described above, has a problem that the spring button cannot be easily flowed due to the lifting force of the insect screen being continuously wound. Larger, of course, there is a closed end of the spring button and the lock key is easily damaged or broken.

Accordingly, each of the two ends of the handle to enter the roots to form a separate independent operation of the heart cam engaging means, by engaging the engaging latch on the guide rail corresponding to these heart cam locking means to operate by the downward pressing force of the handle Heart cam locking means has been improved to achieve a smooth and stable locking state and release state of the handle. Here, the heart cam locking means is a known locking means to repeatedly release the lock from the push-push action that the locking key protrudes by the primary pressing force and the locking key is recessed by the secondary pressing force.

However, as described above, the insect screen and the handle bar to which the independent heart cam locking means are applied are also very inconvenient to use. For example, when the user presses the center portion of the handle downward and the heart cam locking means of both sides operates simultaneously, The release state may occur repeatedly, but when only one end of the handle is pressed, only the heart cam locking means of the corresponding one end operates and the heart cam locking means of the other end does not work. Is released while the other side is still locked so that the desired state is not achieved.

In addition, as described above, the heart cam locking means of one side is locked and the other side of the heart cam locking means presses down the center portion of the handle while being released, so that the locking and releasing states are repeated alternately, thus winding up the insect screen. There is a problem that can not be.

The present invention improves the problems as described above, and inserts a slider having a locking key on both sides of the inside of the handle to be extrusion-molded in the empty state, the slider is hinged to the rotating body coupled to the guide body One side of the slider is connected by the guide body and the heart cam locking means, and the other side of the slider is connected by the guide body and the spring, so that the locking key is guided by the heart cam locking means from both ends of the handle. By configuring to hang out at the same time toward my latch,

Due to the downward pressing force of the handle, the locking keys on both sides operate repeatedly at the same time, which has reasonably solved all the problems of the insect screen locking and releasing means of the existing spring button and the independent object's heart cam locking means. It is an object of the present invention to provide a locking and releasing device of a roller screen.

The present invention for achieving the object as described above, the upper and lower horizontally spaced housing and the chassis member is coupled by a rail member spaced vertically spaced left and right, at the bottom of the insect screen that is deployed or wound from the inside of the housing In the locking and releasing device of the roller screen screen having a handle bar coupled to the locking and releasing device to be coupled to or separated from the lower portion of the rail member,

The locking member is formed at each of the lower ends of the rail member, and guiders are formed on both ends of the handle bar, and the guide body has a slider having a locking key that is protruded through the guider inside the handle bar. Is inserted into the formation, the slider is hinged to be deflected to the rotating body coupled to the guide body, one end of the slider is connected by the guide body and the heart cam locking means, the other end of the slider to the guide body and the spring It is configured to be connected by.

The present invention, the locking keys on both sides through the pressing action of the repetition to the handle bar is fixed or detached to the fastener, so that the switch to the locked state or the release to the wound state can be easily switched to the insect screen, No matter which part of the handlebar is pressed, the lock keys on both sides are released at the same time, so that the screen is locked or released against the insect screen, and the convenience of use is excellent. The effect is to produce a more luxurious exterior.

In addition, the sliders 72 and 72 'on the other side of the sliders 72 and 72' capable of flowing in the lateral direction are connected to the guide body 70 through the spring 100, and the springs described above. 100 is to provide a resilient restoring force to the sliders 72, 72 'continuously so that the sliders 72, 72' operated in the recessed direction to move forward and operate in the protruding direction.

Accordingly, the locking and releasing device of the present invention having the assembly structure as described above allows the deployment state and the wound state for the insect screen while the lock and release are sequentially repeated through the pressing force of the user acting on the handle 60. It is.

Looking at the operation process for the locking and releasing device as described above, by lowering the handle 60 by the artificial force of the user to let the insect screen (40) deployed, the lock and release device inside the handle (60) ( 50 is a state as shown in FIG.

That is, both locking keys 71 and 71 'of the protruding state as the handle 60 descends are formed at the end portions of the locking holes 31 and 31' at the lower ends of the rail members 30 and 30 '. Interfering with the inclined surface 33, the locking keys 71, 71 'protruding according to the interference between each other is recessed into the insertion hole 63 of the guiders 61, 61' at the same time both sliders ( 72 and 72 ′ move toward the guide body 70 with the rotation of the rotor 80.

Accordingly, as both sliders 72 and 72 'are retracted in the recessed direction of the locking keys 71 and 71', the runner 92 is moved from the initial position in the heart cam groove 91, and the spring ( 100 is in a compressed state.

Subsequently, when the user's pressing force on the handle 60, which was subjected to downward pressing force, is removed as described above, the insect screen 40 and the handle 60 are given the winding force by the spring winding device in the upper housing 10. The locking keys 71 and 71 ', which are recessed and retracted by the interference part 34 of the locking holes 31 and 31', are latched by the restoring force of the spring 100. Passing along the inclined surface 33 past the interference portion 34 of the locking keys 71, 71 'protruding the locking grooves 32 of the locking holes 31, 31' as shown in FIG. Insulated and inserted into the inside) the insect screen 40 and the handle 60 is a lock state that can not be raised any more.

In this operation process, the end of the runner 92 in the heart cam groove 91 is moved to the outer end of the heart cam groove 91 so that the sliders 72 and 72 'on both sides are the heart cam groove 91 and the runner 92. Sufficient projection is made without interference by the insertion lock state of the locking keys (71) (71 ') to the engaging holes (31) (31') can be maintained.

Therefore, when the screen 60 is wound inside the housing 10, the handle 60 is lowered to cause the primary interference with the catches 31 and 31 ′ to occur. Since the 71 'is protruded, the locking mechanisms 31 and 31' are engaged with each other, so that the insect screen 40 due to the downward pull can be stably maintained.

In addition, in the expanded state of the insect screen 40 as described above, if necessary to wind up the insect insect screen 40 in a deployed state, the catch 31 coupled to both rail members 30, 30 '( When pressing the handle 60 in the upward restrained state again through 31 '), the locking keys 71 and 71' in the protruding state interfere along the inclined surface 33 of the locking holes 31 and 31 '. It is to be recessed by the part 34, and thus the end of the runner 92 is moved inward along the heart cam groove 91 in accordance with the movement of the sliders 72, 72 'of the lock key 71. The retraction state of the sliders 72 and 72 'including 71' is achieved.

Subsequently, when the downward pressing force on the handlebar 60 is removed, the interference part 34 of the catches 31 and 31 ′ is raised in accordance with the rise of the handlebar 60 receiving the upward winding force of the insect screen 40. The lock keys 71 and 71 'are lifted up and separated from the lock keys 71 and 71'. When the lock keys 71 and 71 ′ in a recessed state start to protrude by the restoring force of the spring 100, the end of the runner 92 is locked to the inner end of the heart cam groove 91 and no longer the lock key ( Since the 71 and 71 'are suppressed from protruding, the locking keys 71 and 71' have a protruding amount so as not to interfere with the locking holes 31 and 31 '. Successive ascents can be made.

This is a general inclined groove that the heart cam groove 91 has as the end of the runner 92 is changed in position in the heart cam groove 91 which flows laterally through the sliders 72 and 72 '. Due to the structure of the shape, the sliders 72 and 72 'which are moved in the recessed retraction direction are suppressed from moving in the protruding forward direction due to the locking force with the runner 92, and are interlocked by the rotating body 80. The sliders 72 and 72 'on the other side are also maintained in the recessed direction while compressing the spring 100.

Accordingly, as described above, the sliders 72 and 72 'including the locking keys 71 and 71' are retracted to maintain a fixed state by the runner 92, so that the insect screen having the upward winding force ( According to the synergistic action of 40, the handle 60 having these locking and unlocking devices 50 can be raised together with the insect screen 40, and when the insect screen 40 is wound in the housing 10, Since the handle 60 is held on the lower portion of the housing 10 to maintain the exposed state, the handle 60 can be fixed by lowering the handle 60 again by artificial force.

In addition, when the handle 60 is pulled down in the above state, the expansion to the insect screen 40 is made, and the locking keys 71 and 71 ′ partially protrude to both ends of the handle 60. Reached to the inclined surface 33 and the interference portion 34 of the locking holes 31, 31 'is to be further recessed due to mutual interference as shown in FIG. 8 is made, the handle 60 When the downward pressing force is removed, the locking keys 71 and 71 ', which are recessed, protrude together with the sliders 72 and 72' and are fitted into the locking grooves 32 of the locking holes 31 and 31 '. The lock to the deployed state to the insect screen 40 is to be made.

Therefore, even if any part of the handle 60 is pressed downward, the locking keys 71 and 71 ′ of both sides of the handle 60 are simultaneously released and operated to lock and roll to the deployed state with respect to the insect screen 40. Since the release is performed sequentially, the convenience of use is further improved while solving the problems of the existing screen lock and release device.

In particular, in the present invention as a means for fixing the position of the guide body 70 built in the handle 60, as shown in FIG. 64, and the stop pin 75 protrudes from the back surface of the guide body 70 corresponding to the stop hole 64.

Here, the stop pin 75 is a process of inserting the guide body 70 into the handle 60 as it is positioned in the cut groove 74 of the "c" shape formed in the guide body 70 Pressing the stop pin (75) in the protruding state by using the incision groove (74), the guide body 70 including the stop pin (75) can be inserted into the inside of the handle 60, the guide body 70 reaches to the middle of the handle 60, the stop pin 75 is a compression pin by the bending moment when the stop pin 75 coincides with the stop hole 64 formed in the handle 60 The guide body 70 can be firmly fixed to the handle 60 while being inserted elastically into the stop hole (64).
