Description

A safety device module for a hoist device and the hoist device using the same}

The present invention provides a roll blind and an awning apparatus for shading and mining the end of one side of a screen having a predetermined width and height of a roll / combi / triple blind in a manner of winding up and down to a rod having a predetermined diameter as a winding member. Tie the bottom of one side of the tow line to the lowermost support member to walk or unfold and pull up the slats one by one by winding up or down the top one end of the tow line inserted into the upper slat through holes formed in the multiple slats. Venetian blinds for shading and mining by raising or lowering, or pleating screen by tying the lower end of one side of the tow line to the support member provided at the bottom of the corrugated screen and lifting or lowering the one end of the upper end of the tow line to the take-up member Honeycomb, pleated blinds, etc. A loop of a hoist device, such as a sunshade, a clothes rack that binds one side end of a predetermined length to a support member and binds the other end to a winding member, and then winds or recommends a tow line to lift or lower the laundry hanging on the support member. The present invention relates to a separate safety device module for preventing a choking accident by a string and a hoist device using the same.

In general, a sunshade, which is a type of hoist device installed indoors or outdoors, is disposed on a window frame to selectively perform mining and mining through a window, and according to its structural features, long slats are arranged in a horizontal direction. Venetian blinds and slats, which flow in the vertical direction and selectively perform light, are placed in the vertical direction, vertical blinds which flow in the left and right direction, selectively perform the light, and a plurality of louvers are provided to be rotated at a fixed position and adjust the angle. Screens such as honeycomb and pleated blinds, which are rolled and laid in horizontal direction, and roll blinds, such as louver type, and roll blinds that flow in the vertical direction to selectively light, and light or shade by folding or unfolding corrugated fabric Types and the like.

Such an awl is usually provided with a pulling member coupled to a supporting member or a winding member which is firmly fixed to an arbitrary fixing member so that the screen itself can be wound or unwound, (Pulled) from a winding member by gravity, and is wound or wound around a winding member by an electric power or a manual power such as a motor, a slat or a screen When the electric power or manual power is not applied to the winding member, it is braked that the winding member is downwardly rotated by the weight of the weight, and at the same time, Which is capable of rotatingly driving the winding member And a drive unit (commonly also referred to as "clutch") is essential.

As another type of hoist apparatus installed inside or outside of the room, there is a laundry dryer. The principle of braking and driving is similar to that of the above-mentioned shovel, so that when no electric power or manual power is applied to the wind- A braking and driving device (hereinafter referred to as " clutch ") for braking the lowering of the winding member by the weight of the weight and at the same time enabling rotation of the winding member when the power is applied is essential.

In addition, there are various hoist devices, but their configuration and operation relationship are quite different and the facts will be obvious to those skilled in the art, so further descriptions of other hoist devices will be omitted below.

FIG. 1 is an exploded perspective view showing a clutch for a roll differential, and FIG. 2 is an exploded perspective view illustrating a clutch for a roll differential. The background art relating to the present invention will now be described.

First, as shown in FIG. 1, the roll blind includes a head rail 1 installed on a window frame; A screen 2 wound on a round bar which is a kind of a winding member disposed on the lower side of the head rail 1 and closed with a lower end bar 3 and upper side rotatably supported on the head rail, And a clutch (4a) which is mounted on one end of the rod (2) and inserted into the round bar to rotatably support the screen (2) and to transmit manual force as a whole from the movable string (6) 4a are supplied to the spring clutch 4a using mostly a wrap spring for various reasons as shown in FIG. 2, but the spring clutch 4a is provided with the engagement portion 4a2 ' A clutch member 4a2 provided with a wrap spring formed therein; A stator 4a1 provided with a clutch member 4a2 inserted therein; The manual pulley 4a3a that rotates with the ball chain 6 or a rotating string (not shown) is rotated and the engaging portion 4a2 'formed integrally with the clutch member 4a2 are engaged with the direction in which the wrap spring body of the clutch member 4a2 is extended A drive member 4a3 which is formed integrally or axially and which is fitted to the outer circumferential surface of the stator 4a1 is provided with drive circuit electrons 4a3b for releasing and rotating the frictional braking force between the stator 4a1 and the clutch member 4a2, ; The protruding protrusion 4a41 is formed so that the outer circumferential surface is fitted into the round bar and the inner circumferential surface is fitted into the driving member 4a3 and the stator 4a1 so as to be pushed in the direction in which the wrap spring body of the clutch member 4a2 is narrowed, And a braking engagement step (not shown) for increasing the frictional braking force between the clutch member 4a2 and the clutch member 4a2. In the drive, the user can rotate the ball chain 6 or the rotating rod (not shown) When the manual pulley 4a3a, which is a constituent of the driving member 4a3, is rotated by the pulling force (in the direction indicated by the solid line in Fig. 3), the driving circuit electron 4a3b causes the latching portion 4a2 ' The frictional braking force between the stator 4a1 and the clutch member 4a2 is released by pushing the spring body in the direction in which the spring body is opened and at the same time the braking engagement step (not shown) of the pickup member 4a4 is pushed and rotated, ) Push the round rod in the direction of rotation to rotate In the braking operation, when the user stops pulling the ball chain 6 or the rotating string (not shown), a rotational force acts on the round bar according to the load of the screen 2, and this rotational force is eventually transmitted to the pick- (Not shown) of the pickup member 4a4 is pushed in the direction in which the lap spring body of the clutch member 4a2 is narrowed (in the direction of the dotted arrow in Fig. 3), and the stator 4a1 and the clutch The frictional braking force between the members 4a2 is increased to thereby stop the round rod itself.

Such a spring clutch 4a allows one mechanical element integrally formed with a wrap spring to braking and driving at the same time, and is very easy to manufacture, and most of all, the value is very low, so that the kind of the awning, The pickup member 4a4 is different from the pickup member 4a4 provided to be connected thereto in accordance with the kind of the hoist device and the same principle can be applied thereto and the driving member 4a3 ) It is also obvious that the detailed configuration or form is varied depending on whether manual or electric power is used or another clutch type is added according to the driving characteristic. However, it is more easily understood by a person skilled in the art, In the case of the spring clutch 4a fitted to the Venetian blind using aluminum slats, The only difference is that a single rotating shaft is further included and the pick-up member 4a4 is provided to rotate a plurality of winding members corresponding to one to one at the same time to use the tow line. It only uses one winding member that can be wound or unwound at a time.

On the other hand, the industry that develops and sells such conventional clutches faces a great problem in recent years, because the ball chain 6 or the rotating shaft (not shown) caught by the above-described drive circuit rotor 4a3b, An endless loop is formed, so that the ball chain 6 and the swinging rope (not shown), which are downwardly pushed down, cause severe choking injury safety problems to the children.

The present inventors have proposed a solution to the prior invention (10-12956840000) (2013.08.06) in order to solve the problem in which the ball chain 6 or the rotating line (not shown) forms an endless loop.

As shown in Fig. 4, in the prior art, a ball chain 6 or a rotating string (not shown) pulled by a consumer is reversely rotated immediately, It can release the endless loop, which is a very useful invention to fundamentally solve children's suffocation problem.

At this time, there are two ways of releasing the endless loop. First, the intuitive method is to cut off the middle of the endless loop to eliminate the endless loop. At this time, The present invention can be applied to a ball chain (6) or a rotating string (not shown), which is pulled by a consumer by pulling up or lowering the blind at both ends of the ball chain (6) (Endless loop) causing a child suffocating accident is not cut off. Therefore, it is difficult to remove the suffocate problem (not shown) because the user does not pull the end ball chain (6) It is a very useful way to solve the problem fundamentally.

Another second endless loop release method is to form an endless loop (Endless Loop), but assembling the loop through two separation means (Breaking away) that is easily separated even under a small load, the consumer is separated means The upper ball chain (6) or the swivel (not shown) can be raised and lowered by the blinds, as well as the reverse rotation of the ball chain (6) or swivel (not shown) after the first invention immediately pulls out The same as the second method, but the other end of the ball chain (6) or swivel (not shown) has the advantage of not squirting, because the separation load of the separation means to be applied can be reduced, so even if caught on the children's neck, it is very easy to separate the choking problem In order to solve the problem, the ball chain 6 or the rotating rope (not shown) is fastened to the above-mentioned conventional clutch through two separating means in the endless loop. This is because the preceding invention is much safer than the case where the rib is not formed because the separation load of the separating means does not need to be increased up to a load that does not cause a problem in raising and lowering the blind fabric at least. In general, when the prior art is applied, a consumer does not need to apply a driving load to the separating means since the consumer holds the ball chain (6) or the rotating string (not shown) Since it is less than about 2 Kg, it is necessary to have a separation load of at least 4 Kg for application to a conventional clutch to which the prior invention is not applied. As shown in Fig.

Looking in more detail through FIG. 4 in order to enable those skilled in the art to understand the prior invention that provides such a safety advantage, when rotating the manual pulley 415a in one direction, but rotates with the manual pulley 415a in one direction In this case, it is possible to include the bidirectional drive clutch 415b for rotating the manual pulley 415a independently of the pickup member when rotating by itself in the opposite direction immediately after rotation together. A bidirectional driver 415b1 coupled to the manual pulley 415a and having a bidirectional moving groove having a small diameter portion 415b1c and a large diameter portion 415b1d on an inner circumferential surface of the body 415b1b; A retainer 415b3 formed on the upper surface of the disc-shaped body and having a unit elastic member holder 415b3a arranged along the periphery of the body; And a roller member 415b2 rotatably inserted between the bi-directional driver 415b1 bi-directional moving groove and the unit elastic member holder 415b3a of the retainer 415b3; And a returning function of the drive wheel member is provided.

At this time, the bi-directional drive clutch 415b of the preceding invention is provided with the reverse rotation means 415d for reversing the retainer 415b3 of the bi-directional drive clutch 415b when the user releases the ball chain or the rotation line to stop the manual operation The retainer 415b3 is provided with a winding member 415b3b provided along the shaft hole 415b3d and the periphery thereof at the center of the disk-shaped body, and a winding member 415b3 for winding or winding the returning rope 415d4 And a plurality of unit elastic member holders 415b3a are formed on the upper surface of the body at regular intervals along the periphery of the shaft hole 415b3d so that both side surfaces of the elastic member 415b are curved in a circular arc with a predetermined diameter .

Briefly describing the principle of operation in such a configuration, when the consumer pulls the ball chain 6 or the rotating line (not shown), the ball chain 6 or the rotating line (not shown) rotates the manual pulley 415a and As the roller member 415b2 is rolled toward the small diameter portion 415b1c while rotating the combined bidirectional driver 415b1, the roller member 415b1c is gradually pressed in the axial direction to hold and rotate a conventional drive rotor (not shown) by frictional force. At the same time, it rotates to the retainer 415b3. As a result, it is pulled up to the reverse rotation means 415d of the retainer 415b3, that is, the lateral side 415d1, to store the force, and the force is later pulled by the ball chain ( 6) or turn the rope (not shown) to reverse the rotation. On the other hand, when the consumer stops pulling, the force stored in the side of the cloth, that is, the resilient force causes the retainer 415b3 to rotate in reverse, which causes the roller member 415b2 to shake toward the large diameter portion 415b1d to release the pressing in the axial direction, The roller member 415b2 rotates the manual pulley 415a while simultaneously rotating the bi-directional driver 415b1 coupled to the bi-directional driver 415b1 while rotating the manual pulley 415a at the same time as releasing from the outer circumferential surface of the rotor (not shown) By biasing the bi-directional moving groove in the rotational direction, the bidirectional driver 415b1 is rotated in reverse, which in turn rotates the pulled ball chain 6 or the rotating string (not shown), and it is essential to operate this behavior in both directions It is a principle.

That is, in the prior art, the roller member 415b2 is moved forward and backward in the axial direction to catch and release a normal drive rotor (not shown) .In the technical background, the characteristics of the one-way clutch by the roller are extended in both directions. It adopts a structure to operate as a basic, but further reinforcement for the blind application, and further includes the lateral side and return rope (415d4) to stably rotate the ball chain (6) or the rope (not shown) as the customer pulls It is a blind safety technology that can fundamentally solve children's choking accidents caused by blinds.

However, the prior art has some problems, the biggest constraint is relatively new technology and expensive price is not quickly supplied to the market and endless loop ball chain 6 or rotation described in Figures 1 to 3 Too many common clutches (sometimes referred to as "loop clutches") using strings (not shown) are still in use today, and hundreds of millions of loop clutches are still in use in the real world. to be.

On the other hand, the present invention is another prior art (10-1677263 [2016.11.11]), the "loop clutch" using the endless loop ball chain (6) or the rotating rope (not shown) that is prevalent Although there was provided a separating means (not shown) connecting to the ball chain (6) for emergency response, but the ball of the ball chain (6) to escape from the separating means (not shown) to prevent children choking accident In order to drive the blinds, there is a technical limitation of another prior art (10-1677263 [2016.11.11]), which must simultaneously perform mutually inconsistent tasks that must not be broken, and must comply with the 6Kg separation loads enforced by current law. Therefore, it is too easy to disconnect from actual use, and it is inconvenient for the consumer to reconnect it each time. Therefore, it is too inconvenient for the consumer to actually drive the blinds, and this inconvenience leads to frequent A / S requests from the supplier, which causes a big problem, so it is easily separated only at the time of suffocation, and the separation is relatively well when the blind is driven. A solution that does not work is very necessary.
