Description

MALFUNCTION PREVENTION HANDLE FOR HORIZONTAL CONTACT TYPE WINDOW

The present invention relates to a malfunction prevention handle for a horizontal contact type window, and more particularly, to a malfunction prevention handle for a horizontal contact type window that is not rotatable if a sash is not contacted with a window frame, so that in the state where the sash is open, the sash is not horizontally movable and lockable.

Generally, a window, which improves insulation, air tightness, pressure resistance, sound proofing, and water tightness and has a variety of opening/closing functions through simple manipulations, is called a 'system window'.

Among such system window, a horizontally sliding window includes a window frame, a fixed window mounted in the window frame, a sash adapted to be open and closed in such a manner as to move along the rails mounted on the window frame to left and right sides, a locking device adapted to lock or unlock the sash to or from the window frame, and a hardware adapted to move the sash in upward and downward directions or in a horizontal direction. The hardware is configured to allow the sash to come into close contact with the window frame in the horizontally moving manner, as shown in FIGS.1 to 2b.

As shown in FIG.1, the conventional hardware includes a frame 10 adapted to move together with a handle unit 102 connected thereto, horizontal moving units 10a operated together with the frame 10 connected thereto in such a manner as to allow the sash to come into close contact with the window frame in the horizontally moving manner, and a well-known locking unit 10b operated cooperatively with the frame in such a manner as to be locked to the fixed window. The horizontal moving units 10a are mounted on the bottom surface of the sash together with rollers 12.

Each of the horizontal moving units 10a has a runner 20 having a body mounted at the close position to a roller housing on which the rollers 12 are located, and a load bar 22 mounted on the runner 20, so that a guide pin 24 provided integrally on the load bar 22 is connected to the frame 10.

The guide pin 24 is moved along a guide slot 32 formed on a guide plate 30, and the guide plate 30 is connected to an arm 40. Further, an extension piece 42 extended from one end of the arm 40 is connected to a restoring spring 50, and the other end of the arm 40 is connected to the roller housing by means of a rotary shaft 44.

Under the configuration of the above-mentioned conventional hardware, if the handle is rotated after the window has been closed, the frame 10 and the guide pin 24 are moved together with the handle, so that the guide pin 24 is moved along the guide slot 32 to pressurize the guide plate 30.

If the guide plate 30 is pressed, the arm 40 located on the underside of the guide plate 30 is rotated around the rotary shaft 44 and at the same time the horizontal moving units 10a and the sash on which the horizontal moving units 10a are mounted are horizontally moved as shown in FIG.1, thereby allowing the sash to be brought into contact with the window frame.

So as to release the locking state, to the contrary, the arm 40 is reversely rotated by means of the restoring spring 50 connected to the extension piece 42 extended from one end of the arm 40, thereby allowing the sash to be separated from the window frame.

By the way, the window having the above-mentioned conventional hardware has some problems.

First of all, even in the state where the sash is open, the horizontal moving units 10a and the locking unit 10b may be operated. That is, if the handle is rotated erroneously by children or users in the state where the sash is open, the frame connected to the handle unit 102 is moved to cause the horizontal moving units 10a and the locking unit 10b to be operated.

Especially, if the sash is pushed and closed in the state where the locking unit is operated to move a lock, the sash is not really locked, which lets an invader to come into the window.

In more detail, the locking unit is operated in the state where the window is not completely closed, thereby rotating a crescent like the lock. In this case, it is misunderstood that the locking state is achieved just by rotating the crescent even though the window is not completely closed, and accordingly, crime prevention such as thief invasion prevention cannot be perfectly accomplished.

According to the conventional hardware, further, a gear box which moves the frame is complicatedly configured, hard in manufacturing process, and is low in the assembling efficiency.

Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a malfunction prevention handle for horizontal contact type window wherein horizontal movement units and locking unit are not operated in a state where a sash is open.

It is another object of the present invention to provide a malfunction prevention handle for horizontal contact type window wherein a handle is completely rotatable only in a state where a sash is brought into complete contact with a window frame, and in a state where the sash is closed, the sash is not openable from the outside, thereby preventing the invasion from the outside.

It is still another object of the present invention to provide a malfunction prevention handle for horizontal contact type window wherein horizontal movement and locking are performed only in a state where a sash is closed, thereby preventing the malfunction and damage of the sash and further reducing the repair cost thereof.

To accomplish the above objects, according to the present invention, there is provided a malfunction prevention handle for a horizontal contact type window having a handle unit mounted on a sash and adapted to move a frame through the rotation thereof in such a manner as to allow horizontal moving units and a locking unit adapted to horizontally move the sash to be operated, the malfunction prevention handle including: a casing disposed at the inside of the sash; the handle unit adapted to be connected rotatably to a bearing provided in the casing; a pinion gear disposed at the internal space of the casing in such a manner as to be operated cooperatively with the handle unit rotated; a rack gear moved upwardly and downwardly in such a manner as to be engaged with the pinion gear, to which the frame is connected; a guide pin fixedly disposed on the rack gear; and a handle rotation prevention member having a rotation prevention plate whose portion protruded outwardly from the sash, the rotation prevention plate having a guide slot formed thereon so as to guide the movement of the guide pin, and the guide slot having a locking projection formed thereon so as to unmovably lock the guide pin to the guide groove, wherein in a state where the sash is open, the guide pin is locked to the locking projection, thereby preventing the handle unit from being rotated, and if the sash is closed to cause the rotation prevention plate to collide against a window frame, the rotation prevention plate is moved toward the sash to release the locking state of the guide pin, so that the handle unit is completely rotated upwardly to operate the horizontal moving units and the locking unit.

According to the present invention, the malfunction prevention handle for a horizontal contact type window restricts the rotation of the handle unit in the state where the sash is open, thereby preventing the horizontal moving units and the locking unit from being operated in the state where the sash is open.

Further, the malfunction prevention handle of the present invention closes the sash in the state where the horizontal moving units and the locking unit are operated, thereby preventing the sash and the window frame from being damaged or malfunctioned.

Furthermore, the malfunction prevention handle of the present invention has a simple configuration and excellent assemblability and makes the hardware operated at a precise position, thereby allowing the window to be usable for a long period of time, without any trouble.

Additionally, the malfunction prevention handle of the present invention allows the locking unit to be operated only when the moving window is completely closed, so that in the state where the window is not completely closed by the user's carelessness, the locking unit is not operated, thereby preventing the invasion from the outside.

A malfunction prevention handle 100 for a horizontal contact type window according to the present invention is desirably applied to the hardware as shown in FIG.1 or to hardware having other configurations, and in some cases, the handle 100 may be applied to other windows.

As shown in FIG.4, the handle 100 of the invention includes a casing 120, a pinion gear 140, a rack gear 160, a cover 180 adapted to be covered on the casing 120, and a handle rotation prevention member 200 coupled movably to the cover 180.

First of all, an explanation on the casing 120 will be given.

The casing 120 is formed of a generally square box in such a manner as to be disposed at the inside of a sash 12 and has an internal space into which a pinion gear 140 and a rack gear 160 are mounted, while having a bearing 122 located at the center of one end thereof. The bearing 122 permits the rotation of a handle unit 102 to be gently performed, and an axis hole 124 is formed at the center of the bearing 122.

A rotary shaft 104 connected to the handle unit 102 is fitted to the axis hole 124, and the pinion gear 140 is mounted on the rotary shaft 104. The configuration will be described below.

As shown in FIGS.4a to 5, the pinion gear 140 and the rack gear 160 are disposed at the internal space of the casing 120, and first, the pinion gear 140 is mounted on the rotary shaft 104 of the handle unit 102, so that if the handle unit 102 is rotated by a user's manipulation, the pinion gear 140 is rotated together with the handle unit 102 rotated.

As shown, teeth are formed on a portion of the pinion gear 140, but they may be formed on the whole outer periphery thereof.

The rack gear 160 is engaged with the pinion gear 140 in such a manner as to be moved upwardly and downwardly, to which a frame 10 is connected.

That is, if the handle unit 102 is rotated by the user's manipulation, the pinion gear 140 mounted on the rotary shaft 124 around which the handle unit 102 is disposed is rotated, and next, the rack gear 160 being engaged with the pinion gear 140 is moved upwardly and downwardly. At this time, the frame 10 connected to the rear surface of the rack gear 160 is moved upwardly and downwardly, thereby operating the hardware, that is, horizontal moving units 10a and a locking unit 10b.

On the other hand, a guide pin 162 is mounted on the rack gear 160 in such a manner as to be moved together with the rack gear 160, and the guide pin 162 is moved along a guide slot 220 formed on a handle rotation prevention plate 240. The configuration will be described later.

The cover 180, which is covered on the casing 120, is fixed to the casing 120 by means of fixing bolts 182 fastened on the upper and lower connection portions thereof, thereby preventing the escape of the gears. Further, the cover 180 has an incised portion formed at the center thereof, to which the handle rotation prevention plate 240 is coupled, and has upper and lower incised faces formed thereon, which serve as slide faces 184 adapted to guide the movement of the handle rotation prevention plate 240.

The handle rotation prevention member 200 includes the handle rotation prevention plate 240 on which the guide slot 220 is formed, and the handle rotation prevention plate 240 is fitted to the incised portion formed at the center of the cover 180. At this time, a portion of the handle rotation prevention plate 240 is protruded outwardly from the sash 12, and if the protruded portion collides against a window frame 14, it is moved toward the sash 12.

So as to absorb the shock caused when the handle rotation prevention plate 240 collides against the window frame 14, the handle rotation prevention plate 240 has a shock-absorbing member 260 mounted on the outer surface thereof, and the shock-absorbing member 260 is made of rubber, synthetic resin, urethane, or other materials.

Further, the handle rotation prevention plate 240 has a moving piece 280 disposed on the upper and lower end portions thereof in such a manner as to be moved along the slide faces 184 formed on the cover 180, and further has the guide slot 220 formed at the center thereof, along which a guide pin 162 formed integrally with the rack gear 160 is fittedly moved.

The guide slot 220 has a locking projection 222, to which the guide pin 162 is locked to prevent the handle unit 102 from being rotated.

That is, the guide slot 220 includes a first guide portion 224 pierced vertically thereon, the locking projection 222 formed by horizontally extending the end of the first vertical guide portion 224, and a second guide portion 226 extended vertically and downwardly from the end of the locking projection 222, which takes a shape of "ㄱ".

Moreover, the handle rotation prevention plate 240 has spring locking slots 204 formed on the upper and lower ends thereof, and one ends of returning springs 202 mounted on the casing 120 are locked to the spring locking slots 204, so that if the handle unit 102 is rotated downwardly, the elastic forces are generated from the returning springs 202 to pull the handle rotation prevention plate 240, and thus, the handle rotation prevention plate 240 is protruded outwardly from the sash 12.

Each of the returning springs 202 is formed of a spiral spring, and in the state of being fixed to the casing 120, each returning spring 202 has one end locked to the casing 120 and the other end locked to each spring locking slot 204, thereby pulling and returning the handle rotation prevention plate 240 through the elastic force generated therefrom.

A reference numeral 300 not explained yet indicates a shock-absorbing member which is mounted on the sash 12 so as to absorb the shock generated at the time of closing the window, and a reference numeral 320 is a shock-absorbing spring mounted inside the shock-absorbing member 300.

Next, an explanation on the installation and operation of the malfunction prevention handle for horizontal contact type window according to the present invention will be given.

First, the casing 120 is mounted at the inside of the sash 12, and the pinion gear 140 and the rack gear 160 are located at the inside of the casing 120. Next, the handle unit 102 is fastened from the outside in such a manner where the pinion gear 140 is mounted on the rotary shaft 104 serving as the center of the rotation of the handle unit 102, and thus, if the handle unit 102 is rotated, the pinion gear 160, the rack gear 160, the frame 10 connected to the rack gear 160, the horizontal moving unit 10a connected to the frame 10, and the locking unit 10b are operated cooperatively with the handle unit 102 being rotated.

According to the present invention, the handle unit 102 being rotated by the user is rotated through three steps as shown in FIGS.3a to 3c.

That is, the state as shown in FIG.3a shows the open window, that is, the state where the sash is open, the state as shown in FIG.3b shows the state where the guide pin 162 is locked to the locking projection 222 of the handle rotation prevention plate 240, and the state as shown in FIG.3c shows the state where the handle rotation prevention plate 240 is moved toward the sash after the sash comes into close contact with the window frame to release the locking state of the guide pin 162. In this state as shown in FIG.3c, if the handle unit 102 is fully rotated upwardly, the horizontal moving units 10a and the locking unit 10b become operated.

The operation of the malfunction prevention handle for horizontal contact type window according to the present invention will be described in more detail. As shown in FIG.4a, the state where the guide pin 162 is located in the first guide portion 224 means the handle 102 moved in the downward direction, and at this time, the sash becomes open.

In the case where the sash is open, it is impossible to operate the horizontal moving units 10a and the locking unit 10b through the rotation of the handle unit 102.

That is, if the handle unit 102 is rotated by the user in the state where the sash is open, the guide pin 162 of the rack gear 160 operated cooperatively with the handle unit 102 is moved along the first guide portion 224, so that the handle unit 102 is rotated by about 90ㅊ. At the moment when the guide pin 224 is locked to the locking projection 222, however, the handle unit 102 is not rotated anymore and stops, so that the horizontal moving units 10a and the locking unit 10b are not operated, which is shown in FIG.4b.

So as to fully rotate the handle unit 102 upwardly, the state as shown in FIG.4c should be provided.

If the sash 12 is pushed by the user to allow the handle rotation prevention plate 240 to come into contact with the window frame, the handle rotation prevention plate 240 is moved toward the sash 12 along the slide faces 184, so that the guide pin 162 is unlocked from the locking projection 222.

In this state, if the handle unit 102 is completely rotated upwardly, the guide pin 162 is moved along the second guide portion 226, as shown in FIG.4d. Of course, if the handle unit 102 is completely rotated, the rack gear 160, the pinion gear 140 and the frame 10 are sequentially operated cooperatively with the handle unit 102, thereby operating the horizontal moving units 10a and the locking unit 10b.

Contrarily, the handle unit 102 is rotated downwardly so as to open the sash, so that the guide pin 162 is moved from the second guide portion 226 to the first guide portion 224, and at the moment when the sash is open, the handle rotation prevention plate 240 is returned to its original position by means of the returning springs 202.

While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
