Description

Unmanned table tennis tables with limited net use

[0001] The present invention relates to an unmanned table tennis table that restricts the use of a net, and more specifically, to an unmanned table tennis table that restricts the use of a net so that a user can use the table tennis table for the amount paid and cannot use the net outside of the time of the amount paid, thereby allowing multiple table tennis tables to be operated unmanned without the need for a manager to be present.

[0002] Table tennis is a sport played on a standard table tennis table, with players passing a table tennis ball back and forth with a racket. It can be enjoyed by a small number of people in a small space at any time, and since the sport itself is not too intense, it is a popular sport that can be enjoyed by people of all ages and genders.

[0003] Additionally, table tennis can be practiced alone, but there are table tennis practice areas or table tennis rooms that are operated for a fee and have multiple table tennis tables so that people can enjoy the game with others.

[0004] A table tennis practice center or table tennis court is a general table tennis table with a net installed between the first and second courts, as in Korean Patent Publication No. 10-1836037, and is operated by charging users for the time they use it. However, there is a problem in that the manager has to manage the users who are using the table tennis table, and there is a problem in that the manager has to be present at all times to check the usage time and collect payment, and if the manager leaves for a moment, the users have to wait, which is quite inconvenient, and there is a problem in that the usage fee may not be paid due to poor management, which may incur economic loss.

[0005] In order to solve the above problem, Republic of Korea Patent Publication No. 10-2553864, entitled Unmanned Table Tennis Table Management Device, was disclosed, but there was a need for further improvement.

[0006] The present invention was created to solve the above-mentioned problems and needs, and the purpose of the present invention is to provide an unmanned table tennis table that allows a user to use the table tennis table for the amount paid, and prevents the use of the net outside of the paid amount, thereby allowing multiple table tennis tables to be operated unmanned without the need for a manager to be present, and thereby restricts the use of the net to create new businesses.

[0007] In order to achieve the above object, an unmanned table tennis table restricting net use according to an embodiment of the present invention includes a net installed vertically along the left-right width direction, a first court and a second court formed symmetrically front-back and rear-backward on a horizontal plane based on the net, a payment means installed near the net so that a stored amount is paid according to a set program, and a net operating means for operating the net according to the payment means, wherein the net operating means can restrict the use of the net through any one of forward-backward tilting rotation, left-right tilting rotation, and up-down elevation.

[0008] According to the present invention, the use of the net can be restricted through any one of forward and backward tilting rotation, left and right tilting rotation, and up and down lifting and lowering through the net operating means, so that there is an advantage in that it can be operated unmanned.

[0009] Additionally, there is an advantage in that multiple table tennis tables can be operated unmanned by laying down or hiding the net so that it is not exposed to prevent use outside of the time the payment method has been used.

[0010] In addition, there is an advantage in that the arm can tilt to one side due to the rotation of the shaft by the rotational power of the driving motor and come into contact with the surface of either the first or second coat, thereby prohibiting and restricting the use of the net.

[0037] In addition, a driven gear (156a) is formed along one side of the outer periphery of the shaft (152) and can rotate in a tilting manner by engaging with a driving gear (156b) mounted on the rotational axis of the driving motor (157).

[0038] In addition, the driven gear (156a) may be a worm wheel, and the driving gear (156b) may be a worm that engages and rotates the driven gear (156a).

[0039] In addition, the net operating means (150') includes an arm (151) that holds the lower part of the net (110), a shaft (152) that connects the arm (151), a holder (153) that supports the shaft (152), and a driving cylinder (157') that is connected to one side of the shaft (152) and rotates in a tilting manner, and the arm (151) can be tilted to one side according to the tilting rotation by pushing one side of the outer periphery of the shaft (152) in the forward and backward movement of the driving cylinder (157') so as to be in close contact with the surface of one of the first coat (120) and the second coat (130).

[0040] In addition, the net operating means (250) includes a first support (251) supporting one side of the net (110), a second support (252) supporting the other side of the net (110), a first hinge holder (253) that rotatably supports the first support (251), a second hinge holder (254) that rotatably supports the second support (252), a belt (255) having a unidirectional protrusion formed connecting the lower portions of the first support (251) and the second support (252), and a second driving motor (257) that moves the belt (255) in the longitudinal direction, and when the belt (255) is moved to one side in the longitudinal direction by the rotational power of the second driving motor (257), the first support (251) and the second The support (252) can be tilted in the same direction and hidden between the first coat (120) and the second coat (130).

[0041] In addition, the belt (255) moves by engaging with the drive gear (256a) mounted on the rotation shaft of the drive motor (155), but the dependent roller (256b) linked with the drive gear (256a) presses the upper portion of the belt (255) to prevent the belt (255) from coming off.

[0044] In addition, the net operating means (350') includes a rail (351) formed in the depth direction at the bottom of the net (110), an LM guide (352) fixed to the bottom of the net (110) and moving along the rail (351), a gripping member (353') connected downwardly to the net (110), and a driving cylinder (357') for elevating the gripping member (353'), and when the gripping member (353') is lowered in the depth direction by the forward and backward movement of the driving cylinder (357'), the LM guide (352) is lowered along the rail (351), so that the net (110) can be hidden between the first coat (120) and the second coat (130).

[0045] Then, the configuration and operation of the unmanned table tennis table (100, 100', 200, 200', 300, 300') that restricts net use according to embodiments of the present invention will be described in detail as follows.

[0046] An unmanned table tennis table (100) according to an embodiment of the present invention, as illustrated in FIG. 1, etc., largely includes a net (110), a first court (120), a second court (130), a payment means (140), and a net operating means (150).

[0047] In particular, the unmanned table tennis table (100) proposed by the present invention can restrict the use of the net (110) through any one of forward and backward tilting rotation, left and right tilting rotation, and up and down lifting and lowering of the net (110) through a net operating means (150), thereby enabling the table tennis table to be operated unmanned.

[0048] That is, the present invention is an unmanned management device for unmanned operation of a table tennis practice range or table tennis room with a plurality of table tennis tables installed, including a payment means (140) installed near the table tennis table and a net operating means (150) for laying down or hiding the net (110) so as not to expose it so as to prevent the net from being used outside of the time for which the paid amount has been paid.

[0049] Here, the net (110) is a mesh-shaped member installed vertically along the X-axis direction of the left and right widths, as shown in Fig. 1, and is formed horizontally across the center of the table tennis table to enable a table tennis game to be played.

[0050] That is, as shown in Fig. 1, the net (110) is formed in the X-axis direction to form a court with a horizontal plane as the boundary, thereby enabling a table tennis game.

[0051] At this time, the net (110) may be closed or its use may be restricted by a net operating means (150) to be described later.

[0052] The first court (120) and the second court (130) are formed symmetrically in the front and back on a horizontal plane based on the net (110) to provide a space in which a table tennis ball can bounce.

[0053] Meanwhile, the first court (120) and the second court (130) are stipulated in the International Table Tennis Association to allow only green or blue as the color, limit the height from the floor, and have a white line 2 cm wide marked around the horizontal surface.

[0054] The table tennis table (100) proposed in the present invention is divided into a first court (120) on one side and a second court (130) on the other side based on a net (110) installed vertically along the width direction, and includes a general table tennis table configuration in which the height is formed by a support supporting the bottom, and a more specific description of the configuration is omitted.

[0055] As shown in Fig. 1, the payment means (140) can be installed and operated near the net (110) so that the stored amount is paid according to a program set by being embedded in a PLC or the like.

[0056] The payment means (140) proposed by the present invention may include a coin dispenser and a card terminal so that the amount stored in the control unit (not shown) can be paid with a card or cash. However, since money may be contaminated with various bacteria and foreign substances, a coin dispenser that inserts coins or bills may not be installed and only a card terminal may be installed and used.

[0057] The payment means (140) is used to limit the use of the net (110) by operating the net operating means (150) in the control unit after the user pays a set amount to use the unmanned table tennis table, thereby allowing the unmanned table tennis table (100, 100',...) proposed by the present invention to be used for a set amount of time.

[0058] The net operating means (150) is a device that operates the net (110) according to the payment means (140), as shown in FIGS. 1 to 10.

[0059] More specifically, the net operating means (150) proposed by the present invention is installed at the lower part of the net (110) and prevents the net (110) from being used unless payment is made at the payment means (140). After a certain amount is paid, the net (110) is exposed and can be ping-ponged to the first court (120) or the second court (130) at the boundary of the net (110).

[0060] That is, the net operating means (150) can prevent the use of the net (110) through any one of forward and backward tilting rotation, left and right tilting rotation, and up and down lifting and lowering of the net (110).

[0061] In particular, the net operating means (150) is installed at the bottom of the net (110) and operates the net (110) as needed, but is not exposed to the outside, so as to prevent an outsider from intentionally destroying or damaging it.

[0062] The net operating means (150) according to the first embodiment of the present invention may include an arm (151), a shaft (152), a holder (153), and a first driving motor (157), as shown in FIGS. 1 to 3.

[0063] Here, the arm (151) is a member that holds the lower part of the net (110) in an “ㄱ” shape to facilitate one-sided adhesion, and enables the net (110) to rotate with the force of the holding.

[0064] Additionally, the shaft (152) is a long, circular member that can rotate by connecting the arm (151).

[0065] Additionally, the holder (153) is fixed to the lower surface of the first coat (120) or the second coat (130) to support the shaft (152) and enable it to rotate about an axis.

[0066] The first driving motor (157) is a motor that receives power and provides rotational power, and is a device that is fixed to the bottom of the first coat (120) or the second coat (130) and can tilt and rotate the shaft (152).

[0067] Accordingly, the net operating means (150) can prohibit and restrict the use of the net (110) by causing the arm (151) to tilt to one side according to the rotation of the shaft (152) by the rotational power of the first driving motor (157) to come into close contact with the surface of either the first coat (120) or the second coat (130).

[0068] Furthermore, as illustrated in FIG. 3, etc., the net operating means (150) has a driven gear (156a) formed along one side of the outer periphery of the shaft (152) and can rotate in a tilting manner by engaging with the first driving gear (156b) mounted on the rotational axis of the first driving motor (157).

[0069] Figure 3 (a) shows a state in which the net (110) is standing up, and Figure 3 (b) shows a state in which the net (110) is lying down.

[0070] Meanwhile, the net operating means (150) according to another embodiment may be a worm wheel in which the driven gear (156a) is a worm wheel, and the first driving gear (156b) is a worm that rotates by engaging with the driven gear (156a), as shown in FIG. 4.

[0071] Figure 4 (a) shows a state in which the net (110) is standing up, and Figure 4 (b) shows a state in which the net (110) is lying down.

[0072] This can reduce the rotation speed of the first drive motor (157) even without installing a separate reduction device, and is used for power transmission when the drive shaft and the driven shaft are perpendicular to each other but not placed on the same plane.

[0073] A net operating means (150') according to another embodiment may include an arm (151), a shaft (152), a holder (153), and a first driving cylinder (157'), as shown in FIGS. 5 and 6.

[0074] Here, the arm (151) is a member that holds the lower part of the net (110) in an “ㄱ” shape to facilitate one-sided adhesion, and enables the net (110) to rotate with the force of holding it in a fixed manner.

[0075] Additionally, the shaft (152) is a long, circular member that can rotate by connecting the arm (151).

[0076] Additionally, the holder (153) is fixed to the lower surface of the first coat (120) or the second coat (130) to support the shaft (152) and enable it to rotate about an axis.

[0077] In addition, the first drive cylinder (157') is a cylinder that provides forward and backward power by receiving pneumatic or hydraulic pressure, etc., and is a device that is fixed to the lower surface of the first coat (120) or the second coat (130) and can tilt and rotate the shaft (152).

[0078] Figure 5 (a) shows a state in which the net (110) is standing up, and Figure 5 (b) shows a state in which the net (110) is lying down.

[0079] Accordingly, as shown in FIGS. 5 and 6, the net operating means (150') pushes one side of the outer circumference of the shaft (152) by the forward and backward movement of the first driving cylinder (157') so that the arm (151) tilts to one side according to the tilting rotation and can come into close contact with the surface of either the first coat (120) or the second coat (130), thereby prohibiting and restricting the use of the net (110).

[0080] For reference, the drive cylinder (157') is a cylinder that receives pressure such as hydraulic pressure or pneumatic pressure and performs linear movement, including the drive cylinders (257', 357') described later, and is installed horizontally in the Y-axis direction on the lower surface of the first coat (120) or the second coat (130) to tilt and rotate by pushing one side of the shaft (152).

[0081] The drive cylinder is a hollow cylindrical shape with its upper and lower surfaces closed, and has an internal piston that can move up and down in a sealed space. As the piston moves by hydraulic or pneumatic pressure on one side, a rod formed on the other side of the piston pushes or pulls one side, such as the outer periphery of a shaft (152), to enable forward and backward movement.

[0082] However, since the driving cylinder is a technology that can be easily derived by a person skilled in the art, such as a general configuration or function, a more detailed description will be omitted, and the cylinder operation or function can be sufficiently understood, and changes can be made within the scope of the technical idea proposed by the present invention.

[0083] According to the second embodiment of the present invention, the network operation means (250) may include a first support (251), a second support (252), a first hinge holder (253), a second hinge holder (254), a belt (255), a second drive motor (257), etc., as shown in FIG. 7 and the like.

[0084] Here, the first support (251) has a columnar shape in a straight line and is vertically formed to be a member that fixes and supports one side of the net (110), and can rotate left and right with respect to the first hinge holder (253).

[0085] In addition, the second support (252) has a columnar shape in a straight line and is vertically formed to be a member that fixes and supports the other side of the net (110), and can rotate left and right with respect to the second hinge holder (254).

[0086] In addition, the first hinge holder (253) is fixed to the side of the first coat (120) or the second coat (130) to support the center of the first support (251), and supports the center of the first support (251) through the center of the first support (251) so that the first support (251) can rotate.

[0087] In addition, the second hinge holder (254) is fixed to the side of the first coat (120) or the second coat (130) to support the center of the second support (252), and supports the center of the second support (252) through the center of the second support (252) so that the second support (252) can rotate.

[0088] In addition, the belt (255) connects the lower parts of the first support (251) and the second support (252) to be elastically movable, and unevenness is formed along the longitudinal direction of the lower surface so as to engage with the gear teeth of the second drive gear (256a) and move.

[0089] In addition, the second driving motor (257) is a motor that receives power supply and provides rotational power. It is fixed under the first coat (120) or the second coat (130), and is a device that can move the belt (255) in the longitudinal direction to tilt and rotate the first support (251) and the second support (252).

[0090] That is, when the network operation means (250) proposed by the present invention moves the belt (255) to one side in the longitudinal direction with the rotational power of the second driving motor (257), the first support (251) and the second support (252) supported by the first and second hinge holders (253) are tilted in the same direction, and the net (110) can be hidden below between the first coat (120) and the second coat (130), so that the use of the net (110) can be prohibited and restricted.

[0091] At this time, as shown in FIG. 7, the network operation means (250) meshes with the second driving gear (256a) mounted on the rotation shaft of the second driving motor (257) and the belt (255) moves. The dependent roller (256b) interlocked with the second driving gear (256a) presses the upper part of the belt (255) to prevent the belt (255) from coming off.

[0092] Furthermore, as shown in FIG. 8, another network operation means (250') proposed by the present invention may include the first support (251), the second support (252), the first hinge holder (253), the second hinge holder (254), the connecting rod (255'), the second driving cylinder (257'), and the like.

[0093] Here, the first support (251) is in the shape of a cylindrical column of a straight line, is formed vertically, and is a member that fixes and supports one side of the net (110), and can rotate left and right with respect to the first hinge holder (253).

[0094] In addition, the second support (252) is a member formed vertically in the shape of a cylindrical I-shape to fix and support the other side of the net (110), and can rotate left and right based on the second hinge holder (254).

[0095] In addition, the first hinge holder (253) is fixed to the side of the first coat (120) or the second coat (130) to support the center of the first support (251), but supports the center of the first support (251) by penetrating through the center of the first support (251) so that the first support (251) can rotate.

[0096] In addition, the second hinge holder (254) is fixed to the side of the first coat (120) or the second coat (130) to support the center of the second support (252), but supports the center of the second support (252) by penetrating through the center of the second support (252) so that the second support (252) can rotate.

[0097] In addition, the connecting member (255') rigidly connects the lower portions of the first support member (251) and the second support member (252) and moves left and right in the X-axis direction according to the operation of the second driving cylinder (257').

[0098] In addition, the second driving cylinder (257') is a cylinder that provides forward and backward movement power by receiving pneumatic or hydraulic pressure, etc., and is a device that is fixed to the lower surface of the first coat (120) or the second coat (130) and can move the connecting member (255') forward and backward.

[0099] That is, the second driving cylinder (257') moves forward and backward to the left and right in the X-axis direction to move the connecting member (255') to the left or right, thereby rotating the first and second supports (251, 252) around the first and second hinge holders (253, 254) to lay down the net (110) in the left and right directions.

[0100] Accordingly, as shown in FIG. 8, when the net operating means (250') moves the connecting member (255') to one side in the longitudinal direction by moving the second driving cylinder (257') forward and backward, the first support member (251) and the second support member (252) supported by the first and second hinge holders (253) tilt in the same direction, so that the net (110) can be hidden between the first coat (120) and the second coat (130), thereby prohibiting and restricting the use of the net (110).

[0101] The net operating means (350) according to the third embodiment of the present invention may include a rail (351), an LM guide (352), a rack (353), a pinion (354), and a third driving motor (357), as illustrated in FIG. 9.

[0102] Here, the rail (351) is formed long downward and is a member that supports the LM guide (352) so that it can move, and is formed in the depth direction at the bottom of the net (110) to support the LM guide (352).

[0103] In addition, the rails (351) may be formed in pairs on the left and right sides of the lower part of the net (110) to support the LM guide (352) or may be operated as one in parallel with the lower side of the net (110) and the rack (353) to be described later.

[0104] In addition, the LM guide (352) is a linear member that is fixed to the lower part of the net (110) in a quantity corresponding to the rail (351) and moves along the rail (351), and moves smoothly and without shaking in the longitudinal direction of the rail (351).

[0105] In addition, the rack (353) is a member in which gears are formed in the longitudinal direction of the letter I and move in mesh with the pinion (354), and is a power transmission gear that is connected downward to the net (110) and converts the rotational power of the pinion (354) into a straight line.

[0106] Additionally, the pinion (354) is a circular gear member that is paired with the rack (353) and rotates in mesh with the linear rack (353) to transmit power.

[0107] That is, the pinion (354) is a circular gear that rotates in mesh with the rack (353) so that rotational force can move in a straight line.

[0108] In addition, the third driving motor (357) is a motor that receives power and provides rotational power, and is a device that is fixed to the bottom of the first coat (120) or the second coat (130) and can rotate the rack (353) and pinion (354) so ​​that they mesh and move.

[0109] For reference, the first to third drive motors (157, 257, 357) may have a built-in reduction device to reduce the rotation speed.

[0110] Accordingly, as shown in FIG. 9, the net operating means (350) lowers the interlocked rack (353) as the pinion (354) rotates with the power of the third driving motor (357), and the LM guide (352) lowers along the rail (351), so that the net (110) can be hidden below between the first coat (120) and the second coat (130), thereby prohibiting and restricting the use of the net (110).

[0111] Furthermore, another net operating means (350') proposed by the present invention may include a rail (351), an LM guide (352), a gripping member (353'), and a third driving cylinder (357'), as shown in FIG. 10.

[0112] Here, the rail (351) is formed long downward and is a member that supports the LM guide (352) so that it can move, and is formed in the depth direction at the bottom of the net (110) to support the LM guide (352).

[0113] In addition, the rails (351) are formed in pairs on the left and right sides below the net (110) and can be operated by supporting the LM guide (352).

[0114] In addition, the LM guide (352) is a linear member that is fixed to the lower part of the net (110) in a quantity corresponding to the rail (351) and moves along the rail (351), and moves smoothly and without shaking in the longitudinal direction of the rail (351).

[0115] In addition, the gripping member (353') is a connecting member that holds the lower part of the net (110) and is connected to the third driving cylinder (357') downwardly of the net (110) so as to raise and lower the net (110) according to the operation of the third driving cylinder (357').

[0116] In addition, the third driving cylinder (357') is a cylinder that provides forward and backward movement power by receiving pneumatic or hydraulic pressure, etc., and is a device that is fixed to the lower surface of the first coat (120) or the second coat (130) and can raise and lower the holding member (353').

[0117] That is, the third driving cylinder (357') can move the net (110) up and down by moving the gripping member (353') up and down in the Z-axis direction.

[0118] Accordingly, as shown in Fig. 10, when the net operating means (350') moves the gripping member (353') in the depth direction by moving the third driving cylinder (357') forward and backward, the LM guide (352) is lowered along the rail (351), so that the net (110) can be hidden in the lower part between the first coat (120) and the second coat (130), thereby prohibiting and restricting the use of the net (110).

[0119] In summary, the unmanned table tennis table (100, 100', 200, 200', 300, 300') according to various embodiments of the present invention restricts or prohibits the use of the net (110) by laying down the net (110) or hiding it so that it disappears below between the first and second courts (120, 130) when a set amount is not paid according to a set program, and when a set amount is paid by a payment means (140), the net operating means (150) is operated to rotate and erect the net (110) or raise and lower the net (110) so that it is normally exposed, thereby enabling the use of the table tennis table.

[0120] In addition, the unmanned table tennis table (100, 100', 200, 200', 300, 300') proposed by the present invention can be operated unmanned, and can operate a table tennis practice center or table tennis room without the need for a manager to be present, thereby creating a new business.

[0121] In this way, the unmanned table tennis table (100, 100', 200, 200', 300, 300') that restricts net use according to embodiments of the present invention can expect the following effects.

[0122] According to the present invention, the use of the net (110) can be restricted through any one of forward and backward tilting rotation, left and right tilting rotation, and up and down lifting and lowering through the net operating means (150), so that there is an advantage in that it can be operated unmanned.

[0123] In addition, the driven gear (156a) is a worm wheel, and the first drive gear (156b) is a worm that rotates by meshing with the driven gear (156a), so there is an advantage in that the rotation speed of the first drive motor (157) can be reduced even without installing a separate reduction device.

[0124] In addition, when the connecting member (255') is moved longitudinally to one side by the forward and backward movement of the second driving cylinder (257'), the first support member (251) and the second support member (252) supported by the first and second hinge holders (253) are tilted in the same direction, so that the net (110) can be hidden between the first coat (120) and the second coat (130), which has the advantage of prohibiting and restricting the use of the net (110).

[0125] In addition, as the pinion (354) rotates with the power of the third driving motor (357), the interlocked rack (353) descends and the LM guide (352) descends along the rail (351), so the net (110) can be hidden below between the first coat (120) and the second coat (130), which has the advantage of prohibiting and restricting the use of the net (110).

[0126] The above description is merely an example of the technical idea of ​​the present invention, and those skilled in the art will appreciate that various modifications, changes, and substitutions can be made without departing from the essential characteristics of the present invention.
