TECHNICAL FIELD [0001] The present invention relates to a safety swing stick tension device for a shovel driving device, and a shovel driving device and a hoist device employing the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sun-blind driving apparatus such as a blind, a louver, and the like, and more particularly to a screen rotating bar of a roll / combination / triple blind, a rotating bar of a Venetian / roman shade / honeycomb blind, (Hereinafter, referred to as " rotating shaft ") or a ball chain for manual driving that pulls the rotating body of the laundry drying table by hand and drives the rotating chain A safety swing stick tensioning device for a sunshade driving device for protecting children's safety, a shovel driving device and a hoist device employing the same.

Generally, a kind of small hoist device installed in a room or outdoor is installed in a window frame so that a mining and mining through a window can be selectively performed, and a long slat is arranged horizontally A venetian blind which vertically moves and vertically moves, a vertical blind which vertically arranges the slats, a vertical blind which selectively moves to the left and right, and a plurality of louvers arranged to rotate at a fixed position Such as a louver type and a horizontally arranged roll, a rolled blind that is rolled up and down to form selective light, and honeycomb and pleated blinds that light or shade by folding or spreading corrugated fabric Screen type.

Such an awl is usually provided with a winding member that is firmly fixed to an arbitrary fixing member such that the towing line or the screen itself can be wound or unwound so as to be rotatable on an arbitrary fixing member, and a weight member is formed or formed by any one of a supporting member, (Pulled) from the winding member by means of gravity, and the pulling line or screen is wound (wound) on the winding member by an electric or manual power such as a motor, and the slat or screen is moved to a specific intended height When the electric power or the 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, when the power is applied, A hoist drive device capable of turning driving Hereinafter referred to as "clutch") is essential.

As a kind of hoist machine installed in a room or outdoors, a laundry drying machine can also be used, which is similar to the above-described awnings. When the electric power or the manual power is not applied to the winding member, It is necessary to provide a hoist driving device which can brak down the rotation and enable the rotation of the winding member when the power is applied.

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 roll blind clutch, and Fig. 3 is a cross-sectional view showing a roll blind clutch. This is a state in which such a clutch is necessary As a representative example, it is selected in detail to explain its composition and operation relationship. The background art relating to the present invention will now be described.

First, as shown in FIG. 1 (a), a roll blind, which is one of conventional shovels, includes a head rail 1a fixedly installed on a window frame; A roll screen 2 disposed on the lower side of the head rail 1a and a wrap spring inserted into one end of the head rail 1a to enable rotation and braking of the roll screen 2 A spring clutch 4a; A cap 5a for closing the other end; As shown in Fig. 1 (b), the roll screen 2 includes a screen 2b provided with a fastening member 2b2 and a screen sheet 2b1; A protruding step is formed on the inner circumferential surface in the longitudinal direction and a hollow inside the screen sheet fastening hole 2a3 is integrally formed on the outer circumferential surface thereof and is provided with a round bar 2a1 for winding and winding the screen sheet 2b1, (2a); The spring clutch 4a is inserted into one end of the winding member 2a and the plug 5a is inserted into the other end of the winding member 2a and the weight of the elongated screen sheet 2b1 is taken into consideration, the round bar 2a1 may further include a deflection reinforcing member 2a2 inside the round bar 2a1 or may be formed integrally with the round bar 2a1 as shown in Fig. Solution), and thus it can be said that it has a very economical structure. The round bar manufacturing method is injection molding with aluminum or plastic material, but the inside is empty due to the manufacturing cost problem.

Such a roll blind is provided on one side of the spring clutch 4a so that the rotating rod 3 is manually operated by the user to rotate the round bar 2a1 as the winding member 2a, The screen 2b of the roll screen 2 is wound around the winding member 2a or wound around the winding member 2a by a method in which the round bar 2a1 as the winding member 2a is rotated by electric power It is recommended to enable selective shading and mining.

2, the spring clutch 4a includes a clutch member 4a2 provided with a wrap spring integrally formed with a latching portion 4a2 '; A stator 4a1 provided with a clutch member 4a2 inserted therein; A latching portion 4a2 'formed integrally on one end of a wrap spring which is a clutch member 4a2 and a swinging member 4a2a which is integrally formed on one end of the swinging member 3 is rotatable about the rotation axis 3, A drive wheel member 4a3 which is integrally formed on the other side and which is fitted to the outer circumferential surface of the stator 4a1 is provided with a drive circuit member 4a3b for releasing and rotating the frictional braking force between the stator 4a1 and the clutch member 4a2, ; A projecting step 4a41 is formed so that the outer circumferential surface thereof is fitted into the screen sheet fastening 2a3 of the round bar 2a1 and the inner circumferential surface thereof is engaged with the driving member 4a3 and the stator 4a1, (Not shown) for increasing the frictional braking force between the stator 4a1 and the clutch member 4a2 is formed in the pickup member 4a4; When the user rotates the rotary pulley 4a3a, which is a constituent of the driving member 4a3, by the pulling force of the rotary string 3 (in the direction of the solid arrow in Fig. 3) The frictional braking force between the stator 4a1 and the clutch member 4a2 is released by pushing the engaging portion 4a2 'of the clutch member 4a2 in the direction in which the wrap spring body is extended, The projecting step 4a41 formed on the outer circumferential surface pushes the screen sheet fastening hole 2a3 of the round bar 2a1 in the rotating direction to rotate the round bar 2a1 as the winding member 2a, When the user stops pulling the rotary string 3, a rotating force is applied to the round bar 2a1 as the wind-up member 2a according to the load of the screen sheet 2b1, and this rotary force eventually causes the pickup member 4a4 (Not shown) of the pick-up member 4a4 to the clutch member 4a2 (In the direction indicated by the dotted line in Fig. 3) by increasing the frictional braking force between the stator 4a1 and the clutch member 4a2, thereby stopping the rotation of the round bar 2a1.

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 that of the pickup member 4a4 provided to be connected thereto in order to apply it according to the kind of the hoist device, 4a3) also have various configurations and forms, depending on whether manual power or electric power is used, or another clutch type is added according to the driving characteristics.

On the other hand, another clutch applied to various hoist devices is a worm and a worm wheel that can be combined with both braking and driving. However, when the plastic material is used, the force can not be maintained. In the case of a metal material, It is difficult to manufacture worms (especially in laundry drying hobs and awnings) due to difficulty in making the worms, and the manufacturing cost is high, so that the application of most of the shovels such as roll blinds and venetian blinds having relatively small loads and relatively low loads The present invention has been applied to a limited range of laundry hats and awnings which are relatively expensive and which require braking, lifting and lowering of a heavy load weight, and various other clutches are known. However, So that they can be easily understood. Detailed description with respect to the braking and driving devices in the host device will be omitted.

However, in order to transmit a human force to a clutch applied to a manually operated hoist apparatus, it is inevitable to use a loop-shaped pulley integrally formed or coupled to the driving member and a loop-shaped rotating barrel of a predetermined length to be fitted thereto, Because the length of the rotary string to be pulled out due to the adoption of the speed reducer to reduce the lift distance or the power felt by the person is larger and diverse than the vertical distance of the lifting distance, the loop rotary string is a very cheap and rational power transmission means, It is used in hoist equipment.

Such a loop type rotating string is usually formed by connecting a straight type ball chain and the end of a cord string to a rotary string pulley for a ball chain having a gear characteristic or a suitable rotary string pulley for a cord string driven only by frictional force .

However, the loop loop has recently become a major cause of social problems because the loop loop is the main cause of accidents in the neck and throat of infants and young children. In order to solve this problem, It has been a fact that many efforts are continuously being made and the alternative which is not worthy to be presented yet.

In order to solve the problem of child suffocation caused by the loop-shaped rotary string, the applicant of the present invention has proposed a driving circuit of a driving wheel member (Sleeve, see Fig. 2, refer to Patent Document 10-1295684, 4a3b are separated from the drive wheel member and rotate together when the rotary pulley is rotated in one direction, but when it rotates itself in the opposite direction immediately after it is rotated together by the rotary pulley in one direction, A bi-directional drive clutch for causing the pulley to rotate independently of the sun shade rotation axis, and a reverse rotation means for reversing the retainer constituting the bi-directional drive clutch when the user releases the rotation line to stop the manual operation, (See 4b in Fig. 4) as a solution, and the detailed construction and operation principle of the shovel driving device Since when the bath below further description will be omitted.

On the other hand, a method for safely using the loop rotation string (see 3 in Fig. 1) on the awning drive device having the function of returning the drive wheel member (see 4b in Fig. 4) will be explained to a person skilled in the art through Fig. (Although the technique of FIG. 4 is not a known technology at the time of the present application).

First of all, as shown in Fig. 4, to make safe the conventional loop rotary string 3 (see Fig. 1) to prevent child suffocation, the loop rotary string 3, which is a typical length of about 1.5 meters, The upper rotating string 3 a is about 50 cm to 70 cm in length with one pulling stroke length by the user and the middle rotating string 3b is about 10 cm to 30 cm, The upper rotary string 3a and the intermediate rotary string 3b are extended so as not to be separated by the use of the two extending members for both stoppers 3d and the intermediate rotary string 3b and the lower rotary string 3c ), A pair of a pair of breaking means (3e, breaking away device), which are separated immediately when the child catches them, are assembled to form a whole loop, and a safety loop 3 ' Loop rotation line ") is inserted into a rotary pulley (not shown) And the height of the upper portion of the safety loop rotation rope 3 'above the both side separation means 3e and the portion of the upper rotation ribs 3a and 3b which are caught by the user (adult) It is possible to divide the child-catching part 3c and the adult-catching part 3a and 3b intentionally by dividing means 3e, When the child catches the lower rotation string 3c, the child is instantly separated and only the adult holds and pulls the upper end and the intermediate rotation rods 3a and 3b above the separation means 3e to drive the awning.

The reason why the safety loop rotation rod 3 'is configured as described above is that, in the case of the upper rotation rod 3a, the length of one stroke that an adult pulls is usually about 50 cm to 70 cm, Since the safety loop rotation rod 3 'is automatically returned immediately after the driving device 4b is pulled out so that the adult can always pull the upper and middle rotation rods 3a and 3b again only at that height, The reason for placing the intermediate rotation string 3b and the stopper expansion member 3d is that the length of the intermediate rotation string 3b is replaced by a longer length in this case, (Not shown) in the case where the first and second stoppers 3a and 3b are excessively pulled to 50 cm to 70 cm or more. At this time, the lower end of the intermediate swivel line (3b) can be placed only at an adult's hand height (about 170 cm) so as not to touch the hand of a child. In this state, that is, even when the lower rotary string 3c is not yet connected, the rotary string pulley can be repeatedly driven. In this case, however, the other rotary string 3a (3b) When you do not, you can twist the bottom. This is because the lower rotating string 3c is connected through the separating means 3e and is also aesthetically pleasing.

It should be noted that if the safety loop rotation rope 3 'is used in the awning driving device 4b having the function of returning the driving wheel member, the nature of the separation means 3e constituting the safety loop rotation rope 3' , There is an essential difference in characteristics as compared with the case of the separating means applied to the loop rotary string used with the conventional spring clutch 4a (see Fig. 2).

For example, when the safety loop rotating rod 3 'is applied to the spring clutch 4a (see FIG. 2), the separating means 3e intervenes in the operation of the awning device, so that the separating means 3e, It is necessary to simultaneously solve the mutually contradictory goals, that is, the driving situation in which the mutual contradictory situation in which the child is separated should not be separated and the child must be easily separated when the child is caught. However, When the safety loop rotating rope 3 'is applied to the awning driving device 4b having the returning function of the separating means 3e, the user drives and drives the rotating ropes 3a and 3b above the separating means 3e, So that the separation means 3e can be easily detached only when the child catches it, but can be attached only to the extent of preventing the child from slipping, So that it is possible to configure the rotation line very safely even if the loop is constituted as a whole

This is a very useful invention that strategically distinguishes the loop rotation line between the position where an adult catches it and the position where a child catches it.

In addition, although not shown in the drawing, another prior application (Patent Application No. 2013-17174) of the present applicant has made it possible to easily manufacture an awning device in aesthetic or functional arrangement with various types of awning devices, If the code is dependent on the rotation of the rotating shaft, it is necessary to pre-wind one side of the rotating shaft to prevent the fine lagging phenomenon that occurs due to the inability to rotate the rotating shaft to the original position. The manual drive wheel of the sunshade drive system driven by the system (the shaft of the rotation shaft is further wound) is also presented, contributing to the safety of the child.

Nevertheless, the position of the upper rotary string 3a and the intermediate rotary string 3b is still lowered to 170 cm from the bottom, so that the children of the frigid are guided through the bed or the chair by the upper rotary string 3a and the intermediate rotary string 3b ), It is possible to avoid the risk of potential suffocation due to the rolling bar at a position of 170 cm or more so as to be a safer solution for the use of the rotary string because of the possibility of the occurrence of potential vomiting accidents. A swing stick tensioning device and a safety cover member used therefor (Patent Application No. 2014-25119) and a safety swing stick tensioning device (Patent Application No. 2014-25667) of a shovel driving device having a handwob (For a more detailed description of this, reference is made to the already filed prior art, so that further explanation will be omitted)

However, the prior application (patent application no. 2014-25667) is perfect for children's safety, but it costs a lot of money due to the use of two walches, and the earlier application (patent application no. 2014-25119) There is a disadvantage that it is not suitable for a hoist device such as a blind having a low height and there is a disadvantage that it is inconvenient to drive because the swing does not occur at a position away from a predetermined position. .
