Description

Single-layer winding type lifting cable drum

The present application requests priority based on korean patent application nos. 10-2021-0034316 and 10-2021-0034320, filed on 3 months 16 of 2021, and all contents of the application specifications and drawings of these applications are incorporated herein.

Technical Field

The present application relates to a single-layer winding type lifting cable reel, and more particularly, to a single-layer winding type lifting cable reel having a structure of winding or unwinding a cable in a lifting manner provided in a ceiling, a wall, or the like.

Background

A socket is an appliance for supplying power in combination with a plug connected to various home appliances or electric appliances, and is generally installed in a landfill type in ceilings, walls, or the like of various facilities.

In a multipurpose facility such as a school, a restaurant, a coffee shop, a hotel, etc., electric appliances are used simultaneously at a plurality of places in a limited space, and thus a large number of sockets are provided on a ceiling, a wall, or a floor of a room, and a method of branching electric wires to a plurality of places by connecting a patch panel to the sockets is also used, if necessary.

Recently, as the use of portable electronic devices such as smartphones, notebook computers, touch panels, etc. is becoming more and more popular, a scene of connecting the portable electronic devices to a socket for charging is often seen in a multi-purpose facility.

However, in the case of using the socket in these multipurpose facilities, not only is the decoration aesthetically unsightly due to the complicated wiring along the indoor wall or floor, but also it is inconvenient to insert or extract the electrical plug into or from the socket, and there is a possibility that a safety accident such as a foot being stumbled by a cable scattered on the floor, or the like may occur.

As an alternative, a technique of providing a cable reel on a ceiling or a wall and connecting a socket at the end of the reel to thereby realize a liftable arrangement is proposed.

For example, korean laid-open patent publication No. 10-1530169 discloses a cable drum socket lifting device that enables winding wires to be stacked in a longitudinal direction to prevent twisting or twisting of the wires, characterized in that a first winding portion and a second winding portion are rotated by a power portion (motor) for continuously supplying power also during rotation for winding or taking out a main power supply line and a socket power supply line, the diameter of the first winding portion is formed smaller than the diameter of the second winding portion, and the length of the socket power supply line drawn out is formed longer than the unwinding length of the main power supply line.

However, the conventional cable drum jack lifting device has a structure in which a motor for supplying a rotational force and a cable winding portion are disposed at a certain distance, and has a limitation in terms of miniaturization of the device, and a problem in that it is difficult to stably lift the jack due to the deviation of the center of gravity to one side.

In addition, when the winding portion rotates, there is a disadvantage in that the structure for preventing the cable for supplying the main power from being twisted is complicated, and thus an alternative is required.

In addition, since a conventional cable reel is configured such that cables are wound on a reel in layers several times, eddy currents (Eddy current) between cables adjacent to each other layer by layer are induced when power is supplied, and heat generation and fire occurrence may occur in some cases.

In addition, in the event of a meal or enjoying leisure life such as a game play, a dart (dart), a betting (betting) reel, a dice, etc., in a job site or various parties, there are many cases where game props are used.

However, the props used for games are generally discarded after disposable use, and the game devices such as darts and betting reels have large volume and poor portability, and occupy occupied space after the use is finished, which becomes a factor for preventing the interior decoration of facilities from being attractive.

Alternatively, korean patent publication No. 10-1921684 proposes a portable wheel device that can be rotated with various forms of containers or bottles inserted therein and has improved portability. Specifically, korean patent publication No. 10-1921684 discloses a portable wheel device, which is characterized by comprising: a bracket with an inner space opened to the upper part; a lower rotating shaft detachably coupled to the bracket, formed to protrude from the upper portion toward a predetermined position, and including an indication portion in which an indication tip of the battery is embedded; the battery forms a luminous unit, and is combined with the bracket and the indicating part to form a display part rotating outside the rotating shaft, when the bracket, the indicating part and the display part are combined, a part of the bracket protrudes to the lower part of the display part and is formed on a horizontal line different from the display part, when a part of the bracket is inserted into a cover of a container or a bottle, and when the side surface of the display part is pushed in one direction, the display part rotates by taking the rotating shaft as a reference.

However, the portable roulette device as described above is personal and portable, and is not suitable for being installed in a multi-purpose facility such as a restaurant, a cafe, a bar, etc., and is simultaneously shared by a plurality of persons.

In order to achieve the above object, the present application provides a single-layer winding type lifting cable drum, comprising: a body arranged on the ceiling, the wall or the support body with a preset shape and provided with an accommodating space inside; a hollow reel rotatably accommodated in the body, the cable being wound around the peripheral surface of the body; a driving motor disposed in the hollow to provide a rotational force in a forward/reverse direction to the spool; a slip ring provided at a part of the reel and receiving commercial power by a contact system; and a lifting body suspended at the lower end of the cable and arranged in a lifting manner, wherein the cable is wound on the circumferential surface of the winding drum in a single layer so as to prevent heat generation caused by eddy current.

Preferably, the last coil of the cable is aligned with the center of the body in a state that the cable is wound on the drum, and the center of the lifting body is aligned with the center of the body in a state that the lifting body is combined with the lower portion of the body in a state that the lifting body is lifted as the winding of the cable is completed.

On the circumferential surface of the drum, a guide groove accommodating a part of the outer circumferential surface of the cable may be formed to extend in a spiral shape along the length direction of the drum so that the cable is wound at a predetermined pitch.

At least one portion of the guide groove may be formed with a position adjusting hole communicating with the hollow of the drum, which is a starting point of the cable winding around the circumferential surface of the drum.

A plurality of the position adjustment holes may be alternately formed with respect to the guide grooves repeated toward the length direction of the drum so that a start point of winding around the circumferential surface of the drum can be selected according to the entire length of the cable.

In order to secure rigidity of the spool, the position adjustment holes may be formed so as to be staggered in multiple directions with respect to a rotation center axis of the spool.

Additionally, the cable guide roller may further include at least one guide roller fixed to an inner bottom surface of the body and disposed at a lower portion of the drum to guide the cable unwound from the drum to a lower portion of the body.

A microcomputer sensing tension applied to the cable to detect a non-compliance state or detecting an overload state to perform control of automatically stopping the operation of the driving motor may be further included.

The microcomputer may also perform slow zone control of reducing the rotational speed of the drum to prevent impact between the body and the drum before the elevation body is elevated to be combined with the body.

The microcomputer may also perform an automatic stop control of sensing the elevating body when it reaches a preset height to stop the operation of the driving motor.

The lifting body may be configured as a socket in which at least one plug insertion opening is formed.

The lifting body may further include a receiving portion provided on at least one side of the lifting body to selectively open the internal receiving space.

The cable hole is provided with a plurality of compression blocks around the periphery, the compression blocks are configured to surround the cable, and the plurality of compression blocks compress the cable while selectively clamping bolts in contact with the outer surface of the compression blocks to push the cable in the cable direction, so that the cable can be fixed on the lifting body.

Alternatively, the lifting body may be composed of a lifting body suspended from a lower end of the cable, a rotary game device rotatably provided on one surface of the lifting body, and a turntable formed by dividing a betting area portion selected from at least any one of a sentence, a number, an image, and a color in a circumferential direction.

Technical effects

The single-layer winding type lifting cable drum has the following effects:

first, since the cables are wound on the reel in a single layer, eddy current can be prevented from being induced between adjacent cables. Therefore, even if electricity is used in a state where all or part of the cable is wound around the drum, substantially the same electric safety effect as that of completely unwinding the cable from the drum and using the same can be obtained.

Second, by the construction that the last Turn (Turn) of the cable is located on the same vertical line as the center of the body in the state that the winding of the drum is completed, the center of the lifting body is accurately aligned with the center of the body at the end of the lifting body, so that the device can be constructed compactly as a whole and the beauty of the decoration can be maximized.

Third, since the drive motor and the gear portion are disposed in the hollow of the cable drum to rotate the cable drum, the device can be miniaturized as compared with the conventional art in which the drive motor and the gear portion are disposed outside the cable drum.

Fourth, since the commercial power is transmitted to the cable through the slip ring by the contact system, the cable can be prevented from winding when the drum rotates, and the power transmission structure can be simplified.

Fifth, the cable can be wound around the circumference of the drum at a predetermined pitch, and the winding of the cable at the midpoint of the drum can be completed by selecting the winding start point and setting the end of the lifting body. Therefore, the load applied to the spool can be prevented from being biased to one side.

Sixth, the plurality of position adjustment holes are formed so as to intersect each other on both sides with respect to the rotation center axis of the spool, whereby the rigidity of the spool can be prevented from being lowered.

Seventh, under the condition that no load or overload of the driving motor is detected, the driving motor can be automatically stopped to prevent safety accidents.

Eighth, by installing the spinning game device on the ceiling of the utility facility, the game can be enjoyed independently on each table, and after the game is finished, the game device can be lifted up and down to the ceiling, thereby improving the space utilization efficiency and improving the appearance of the decoration.

Ninth, the deceleration mode is controlled by detecting the rotation speed of the roulette, thereby enabling to provide more colorful game or activity services.

Detailed Description

Fig. 1 is a perspective view of a single-layer winding type lifting cable reel according to a preferred embodiment of the present application, fig. 2 is a sectional view of fig. 1, fig. 3 is a perspective view showing a lowered state of the lifting body of fig. 1, and fig. 4 is a sectional view of fig. 3.

Referring to fig. 1 to 4, the single-layer winding type lifting cable reel according to the preferred embodiment of the present application includes a body 100 provided at a ceiling level, a reel 101 rotatably received in the interior of the body 100, a driving motor 104 fixed to the body 100 and providing a rotational force to the reel 101, a gear part 105 decelerating the rotational force of the driving motor 104 and transmitting to the reel 101, and a lifting body 120 suspended to the cable 102 to be capable of lifting.

The body 100 is provided in a ceiling or a wall inside a building, or a support body of a predetermined shape such as a pole (pole) or a building column. The shape of the body 100 is not limited to the example shown in the drawings, and various modifications are possible. The body 100 has an accommodating space in which the spool 101 can be accommodated.

The reel 101 is rotatably housed inside the main body 100, and the cable 102 is wound around the peripheral surface. The entire length of the cable 102 wound around the drum 101 may be selected according to the setting environment. From the viewpoint of electrical safety, it is preferable that the cable 102 is in a fully unwound state from the drum 101 when the lifting body 120 is completely lowered at a desired position.

The inside of the spool 101 is formed with a hollow and a partition 103 partitioning the hollow. That is, the spool 101 has a hollow structure formed on both sides with respect to the partition 103.

As shown in fig. 1, in a state where the winding of the cable 102 is completed, the last turn (T _L ) Are aligned on the same vertical line (a) as the center of the body 100. The position of the spool 101 with respect to the body 100 or the winding start point of the cable 102 is determined as a place satisfying such an alignment condition. According to this configuration, when the lifting body 120 is lifted up and coupled to the lower portion of the main body 100 by the completion of winding of the cable 102, the center of the lifting body 120 is accurately aligned with the center of the main body 100, and thus the beauty of the decoration can be maximized.

The slip ring 106 is disposed on the other surface of the bulkhead 103, that is, on the right side of the bulkhead 103, and is a member for receiving commercial power by a contact system. The Slip ring 106 is configured to continuously hold a pair of contacts in contact with each other while the spool 101 rotates, and to receive commercial power while sliding (Slip) and rotating. One side of the slip ring 106 is fixed to a one-side vertical plate 108b of a bracket 108 described later.

At least one wire through hole 103a is formed in the thickness direction in the partition wall 103. Accordingly, the core wire stripped by the armor of the end portion of the cable 102 can be inserted into the hollow of the drum 101 through the position adjusting hole 101a formed in the drum 101 and connected to the slip ring 106 through the wire through hole 103a. Alternatively, additional connection wires may be added between the input end of the cable 102 and the slip ring 106.

An optical sensor 107 is disposed on the peripheral side of the slip ring 106 to detect the rotation amount of the spool 101. The light emitting element and the light receiving element of the photosensor 107 are arranged to face each other with the edge end of the slip ring 106 therebetween.

On the outer peripheral surface of the drum 101, a guide groove 101b accommodating a part of the peripheral surface of the cable 102 is formed to extend in a spiral shape along the length direction of the drum 101 so that the cable 102 is wound at a predetermined pitch.

At least one portion of the guide groove 101b is formed with a position adjustment hole 101a communicating with the hollow of the spool 101 to be a starting point at which the cable 102 is wound around the outer peripheral surface of the spool 101. The position adjustment holes 101a are formed in a plurality of alternating patterns with respect to the guide grooves 101b which repeat toward the longitudinal direction of the spool 101.

The cable 102 is wound around the circumferential surface of the reel 101 in a single layer (one layer), and a starting point of winding around the circumferential surface of the reel 101 can be selected in consideration of the entire length of the cable 102.

The position adjustment holes 101a are formed so as to be staggered in a plurality of directions with respect to the rotation center axis of the spool 101. According to this configuration, the length sections of the spool 101 in which the position adjustment holes 101a are formed are dispersed, so that the stiffness of the spool 101 can be ensured. In this regard, examples in which the upper position adjustment holes 101a are formed in the grooves No. 1, no. 3, and No. 5 in fig. 2 and fig. 4 are shown, and examples in which the lower position adjustment holes 101a are formed in the grooves No. 2, no. 4, and No. 6 are shown.

The ascent stop limit switch 109 is fixed to the inner bottom surface of the body 100, partially penetrates the lower surface of the body 100, is exposed to the outside, and is brought into contact with the upper surface of the elevating body 120 to operate when the ascent of the elevating body 120 is completed. When the ascent stop limit switch 109 operates, a predetermined microcomputer (not shown) interrupts winding by stopping the driving motor 104.

The guide roller 110 is fixed to the inner bottom surface of the body 100, and at least one is disposed at the lower portion of the drum 101 to guide the cable 102 unwound from the drum 101 to the lower portion of the body 100.

Additionally, a no-load limit switch 112 may be connected to the rotation shaft of the guide roller 110. The no-load limit switch 112 can detect the grounded state of the lifting body 120 by sensing the tension applied to the cable 10 unwound from the drum 101. For example, when the power is supplied to the drive motor 104 to lower the elevating body 120, if the elevating body 120 reaches the ground and the tension is reduced, the tension applied to the guide roller 110 is changed to activate the no-load limit switch 112.

A bracket 108 having a substantially '' shape, which is disposed so as to surround the drum 101, is fixed to the bottom surface of the main body 100, and supports the drum 101, the driving motor 104, and the gear unit 105. The bracket 108 is constituted by a pair of vertical plates 108a, 108b and a horizontal plate 108c interconnecting the upper ends of the pair of vertical plates 108a, 108b. A pair of vertical plates 108a and 108b are disposed at both ends of the spool 101, respectively. The rear end of the drive motor 104 is fixed by bolting one vertical plate 108a of a pair of vertical plates 108a, 108b, and the optical sensor 107 and one side of the slip ring 106 are fixed to the other vertical plate 108b.

The mounting piece 111 is a coupling member for disposing the body 100 on a ceiling, a wall, or a support body of a predetermined shape. The mounting piece 111 is formed by partially cutting and bending the middle point of the horizontal plate 108c and protruding to the upper outer side of the body 100. The attachment piece 111 has coupling holes 111a through which coupling elements such as bolts and screws pass.

The driving motor 104 is directly or indirectly fixed to the body 100 and disposed in the hollow space on one side of the spool 101. A gear unit 105 composed of a reduction gear unit for reducing the rotational force of the drive motor 104 and transmitting the reduced force to the spool 101 is connected to the rotation shaft of the drive motor 104. The output end of the gear portion 105 is clamped and fixed to the center of one surface of the partition 103 to transmit rotational force to the spool 101.

The driving motor 104 is composed of a Direct Current (DC) motor, and a braking resistor having a preset resistance value is connected between two ends of a power input terminal of the driving motor 104, so that the winding drum 101 is not rotated by the self load of the lifting body 120 in a static state of the lifting body 120 or is not rotated when a preset tension is not reached.

Alternatively, the reduction gear ratio of the gear portion 105 may be set to a sufficiently large value so that the spool 101 is not rotated by the lifting body 120 itself in a stationary state or is not rotated when a preset tension is not reached.

The driving motor 104 may be configured to actively rotate by a power source to lower the elevating body 120 when a large force equal to or greater than a predetermined high load or a tensile force is applied to the elevating body 120. Preferably, a direct current motor may be employed as the driving motor 104.

A microcomputer (not shown) responsible for controlling the driving motor 104 detects a no-load and an overload state applied to the driving motor 104, and performs control to automatically stop the operation of the driving motor 104. For this, an encoder (not shown) for detecting the rotation amount of the driving motor 104 may be provided at one side of the driving motor 104. The microcomputer detects the rotational speed of the driving motor 104 from the count value of the encoder, and can determine the no-load or overload state based on this.

The microcomputer may also perform slow zone control of reducing the rotational speed of the drum 101 before the elevating body 120 is elevated and combined with the body 100 to prevent the impact between the body 100 and the drum 101. Here, the microcomputer performs control of repeatedly opening/closing by outputting a pulse signal to the driving motor 104 so that the spool 101 is slowly coupled to the lower portion of the body 100.

And, the microcomputer may further perform an automatic stop control of sensing the elevation body 120 when it reaches a preset height by a user and stopping the operation of the driving motor 104. Here, the microcomputer recognizes the position of the elevating body 120 from the rotation amount detected by the encoder, and outputs a control signal for stopping the operation of the driving motor 104 when the elevating body 120 reaches a preset position. For example, since a lot of moisture is present on the floor in the canteen kitchen, the lifting body 120 can be set to descend and automatically stop when it is located at a position of several tens cm from the floor.

The lifting body 120 may be configured as an electrical outlet suspended from the cable 102 and provided with at least one plug insertion opening 121 on one side. Preferably, the elevating body 120 is formed of a plastic injection molding in a disc shape. According to this configuration, the device can be made compact as a whole because the device is closely attached to the center of the lower surface of the body 100 when the ascent is completed.

The lifter 120 has a structure in which the cable 102 is guided to the center of the upper surface, and a plurality of plug insertion openings 121 are symmetrically arranged on both sides with respect to the center. That is, the elevating body 120 is configured such that the plug insertion opening 121 of the electrical outlet is exposed to the upper surface of the disk structure. According to this structure, when the upper surface of the lifter 120 is coupled to the lower portion of the main body 100 after the lifter 120 is lifted, the plug insertion opening 121 is not exposed to the outside, which is advantageous in terms of electrical safety and ornamental appearance.

A wireless charging part (not shown) is built in the elevating body 120, and supplies wireless power to one surface (preferably the upper surface) of the elevating body 120 in an electromagnetic induction or resonance induction manner to provide a wireless charging function to a predetermined portable electronic device such as a smart phone placed on the elevating body 120.

The single-layer winding type lifting cable reel with the structure can be applied to multipurpose facilities such as schools, dining halls, coffee shops, hotels and the like. The single-layer winding type lifting cable reel is preferably provided at a ceiling to charge portable electronic devices such as a smart phone, a notebook computer, a tablet computer, etc., corresponding to each desk, or to provide an electrical outlet coupled to plugs of various laboratory appliances, electric heating appliances, video conference devices, etc.

The user can operate the single-layer winding type lifting cable drum through the wireless remote controller, and the lifting body 120 is lifted as shown in fig. 2 and 4. The lifting body 120 is positioned in the air on a desk or is placed on the desk surface, and then a plug of a device requiring power supply is inserted into the plug insertion opening 121. Alternatively, the user may pull the elevating body 120 downward by hand to lower it. Here, the single-layer winding type lifting cable drum is set by the braking resistance or the gear reduction ratio, and does not drop when the set load or the tension is not reached, so that the safety accident can be prevented.

When the power supply is used, the user can operate the wireless remote controller to raise the lifting body 120 and reset it to the ceiling as shown in fig. 1 and 3. When the winding operation of the drive motor 104 is performed to raise the lifting body 120 and reach the lower surface of the main body 100, the upper surface contacts the raising stop limit switch 109 to stop the raising. The position adjustment hole 101a is selected in accordance with the cable length in the setting process before use of the cable 102, so that the cable 102 can be accurately set to be wound on the circumferential surface of the drum 101 in a single layer when the lifting body 120 is finished lifting, and the winding of the cable 102 can be completed at the midpoint of the drum 101. Further, the load applied to the elevating body 120 can be prevented from being biased to one side.

When the lifting body 120 is lifted, the lifting body is closely attached to the center of the lower surface of the body 100. The elevating body 120 may be buried such that a lower face is aligned with a surface of the ceiling, and may be convexly provided as an external type as an alternative.

As shown in fig. 5 and 6, the lifting body 120 has an eye bolt 105 coupled to the center thereof and a cable connector 151 coupled to the periphery thereof, so that electrical devices such as a lighting device 160 can be easily mounted and used on the lower portion of the lifting body 120.

As shown in fig. 7, the housing portion 161 is provided on at least one side of the elevating body 120, and is provided to selectively open the internal housing space 162. As shown, the receiving portion 161 may be configured as a drawer type, and alternatively, may be configured as a pop-up type that is selectively rotated and protruded. The receiving portion 161 may be connected with a predetermined spring (not shown) applying an elastic force in a direction pulling toward the inside of the elevating body 120. Living goods such as toothpicks, bottle drivers, fragrances, candies, and the like, or sundries can be accommodated in the inner accommodation space 162 of the accommodation portion 161.

The multi-purpose rack 163 is disposed at the lower part of the elevating body 120, and has a storage surface 163a on which an object can be placed and a pair of support plates 163b extending upward from the storage surface 163 a. A pair of support plates 163b are provided to be freely shakable with end portions thereof connected to both side surfaces of the elevation body 120 by means of pivots 164. The storage surface 163a may be provided with objects such as a card reader, an automobile charging wire, a speaker, and a camera. Even if the center of gravity of such an object is biased to one side on the storage surface 163a, the multi-purpose rack 163 is always kept in a state of being suspended from the elevating body 120 in the gravity direction by the pivot 164, and thus stable storage can be realized.

Fig. 8 shows a bottom surface configuration of the lifter 120. As shown in the figure, when the cable 102 is introduced into the cable hole 166 located at the center of the lifting body 120, the cable 102 can be firmly fixed to the lifting body 120 because the cable 102 moves in the direction of the cable 102 from the compression block 164 surrounding the cable 102. For this purpose, semicircular bolt holes 165 corresponding to each other are formed in the outer surface of each compression block 164 and the inner circumferential surface of the circular rib of the elevating body 120 corresponding thereto. Accordingly, in a case where a predetermined bolt is selectively clamped into the bolt hole 165 and tightened, the distal end portion of the bolt contacts the compression block 164 while the compression block 164 is pressed inward to press the cable 102, so that the cable 102 can be firmly fixed to the elevating body 120.

Fig. 9 to 14 show a single-layer winding type lifting cable drum according to another embodiment of the present application. In the drawings, the same reference numerals as those of the foregoing embodiments belong to the same components, and detailed description thereof will be omitted.

As shown in fig. 13 and ' B ' of fig. 14, the elevating body 120' is composed of a rotary game having an elevating body 122 suspended from the cable 102 and a turntable 123 rotatably assembled on one surface (preferably, the lower surface) of the elevating body 122.

The lifting body 122 is formed of a disk-shaped plastic injection molding or a lightweight aluminum material, etc. According to this configuration, the device can be easily buried in the center of the lower surface of the body 100 and can be easily attached to the ceiling when the ascent is completed, and the device can be made compact as a whole.

The turntable 123 is rotatably disposed under the elevating body 122. For smooth rotation of the turntable 123, the ball bearing 130 is interposed between the turntable 123 and the elevating body 122, and a fixing bolt 131 is coupled to the center of the turntable 123 to fix the inner wheel sandwiching the ball bearing 130. A betting area portion 124, which is distinguished from each other by at least one selected from the group consisting of letters, numerals, images, and colors, is formed in a circumferential direction of a planar portion of the turntable 123. Various contents corresponding to the game types can be printed in the betting area portion 124. For example, the betting area 124 may record the' dry cup-! ' singing Bar-! ' parent-! ' buy order-! ' sign in-! ' etc.

As shown in fig. 10, a rotating member 128 is fixed to the upper surface of the turntable 123 which is not exposed to the outside, and a sensing member 129 which contacts the rotating member 128 to detect the rotation amount such as the rotation speed of the turntable 123 is fixed to the elevating body 122. The rotating member 128 has a structure having a rotation center aligned with the center of the turntable 123, and repeatedly forming valleys and peaks at a set pitch along a substantially circular circumference. The sensing member 129 is constituted by a limit switch, and the roller portion is held in contact with the valley and peak structure of the rotating member 128 when the dial 123 rotates. Alternatively, through holes are repeatedly formed at predetermined intervals along the circumference of the rotating member 128, and the sensing member 129 may be also constituted by a photosensor opposite to the through holes.

To control the deceleration of the turntable 123, an electromagnet 127 is fixed to the lower edge side of the elevating body 122, and a magnetic member 126 capable of rotating opposite to the electromagnet 127 is attached to the upper surface of the turntable 123. The magnetic member 126 is made of a ferromagnetic material such as an iron plate or a permanent magnet, and magnetically interacts with the electromagnet 127. When the electromagnet 127 is supplied with power during rotation of the turntable 123 such that the electromagnet 127 has magnetism of a predetermined magnitude, the rotational movement of the turntable 123 is hindered by attractive force acting between the electromagnet 127 and the magnetic member 126, thereby accelerating deceleration.

A spinning game artificial intelligence microcomputer (not shown) is built in the elevating body 122, and when a user rotates the turntable 123, calculates a rotation period and a speed with reference to a predetermined recognition protrusion (or recognition groove) provided at a certain point of the rotating member 128, and performs deceleration control based on a Machine Learning (Learning) algorithm that controls the electromagnet 127 to adjust a stop position using a magnetic force of interaction between the electromagnet 127 and the magnetic member 126 based on a result of prediction of empirical data of the stop position corresponding to each rotation speed. That is, if the deceleration control is not performed, the turntable 123 is rotated by the force F1 and then stopped after, for example, 10 rotations, and if the electromagnet 127 is controlled by the artificial intelligence microcomputer, the turntable 123 can be controlled to be rotated by the same force F1 and then stopped at, for example, 7.5 rotations. The artificial intelligence microcomputer is based on the information about each rotation period and rotation speed (V ₁ ,V ₂ ,V ₃ ,...V _n ) Is at a stop position (P) ₁ ,P ₂ ,P ₃ ,...P _n ) Learning of empirical data of (a), for example, the rotation speed of the dial 123 is V ₇ Is predicted P under the condition of (1) ₇ The value is the stop position. Here, the avoidance corresponds to P ₇ If the other specific betting area 124 corresponds to P ₇ In the case of (a), the artificial intelligence microcomputer can perform control of decelerating the turntable 123 by the electromagnet 127 to stop the betting area part 124 at the position of the fixed logo 125. The artificial intelligence microcomputer accumulates control or empirical data for the electromagnet 127 for learning.

The single-layer winding type lifting cable reel with the structure can be applied to multi-purpose facilities such as restaurants, cafes, hotels, suburbation places, home hotels and the like. A single-layer winding type lifting cable reel is preferably provided at the ceiling corresponding to each desk, and provides game or activity services when necessary.

The user can lower the elevating body 120' as shown in fig. 12 and 13 by operating the single-layer winding type elevating cable drum with the wired or wireless remote controller. The lifting body 120' may be located in the air on a table or fall on a table top. Alternatively, the user may also pull the lifting body 120' downward by hand to descend. Here, the single-layer winding type lifting cable drum detects the rotation amount of the driving motor 104, and automatically stops the driving motor 104 when no load, overload, reaching a set position, or the like is necessary, thereby preventing a safety accident.

After the lifting body 120 'is lowered, the user holds the lifting body 122 or the cable 102 to turn over the lifting body so that the turntable 123 located below the lifting body 120' faces upward, and flicks a finger to rotate the plane portion of the turntable 123.

A plurality of game or activity sentences are printed or inscribed in advance in the betting area section 124 of the roulette 123. For example, with a' dry cup-! 'or' affinity-! In the case of an active sentence such as 'and the like', the atmosphere can be further activated and the pleasure can be increased in the occasion such as a friend party or wedding banquet. Also in this case, the manager of the single-layer winding type lifting cable reel actively controls the deceleration of the dial 123 by the non-public operation of the deceleration control function of the artificial intelligence microcomputer even if the dial 123 is rotated in any way by the owner of the party so as to stop at the specific betting area section 124-for example, at the time of making' parent-! ' stay in place with the fixed identification 125, thereby being able to provide more fun to the party participants.

When a portable device such as a smart phone needs to be charged, a plug insertion opening of a socket exposed on the upper surface of the lifting body 122 may be used, or a wireless charging function may be used by placing the portable device on the upper surface side of the lifting body 122.

At the end of the game, the user operates the wireless remote controller to raise the elevating body 120' and can reset it to the ceiling as shown in fig. 9 to 11. The lifting body 120' is lifted by the winding operation of the driving motor 104, and when reaching the lower surface of the main body 100, the upper surface comes into contact with the lifting stop limit switch 109 to stop lifting. The position adjustment hole 101a is selected during the installation of the cable 102 before use, so that the cable 102 can be wound at the center of the drum 101 accurately when the lifting of the lifting body 120 'is completed, and thus the load applied to the lifting body 120' can be prevented from tilting to one side.

After the game is finished, the lifting body 120' is lifted to the ceiling, so that the space utilization efficiency can be improved, and the decoration appearance can be improved.
