Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a table tennis table in which a top table supporting device having a rubber support that can be finely adjusted vertically is attached to a folding table tennis table having only main legs.

[0002]

[Prior art]

 Conventionally: there were foldable table tennis tables with only the main legs or separate legs.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. (A) In the folding table tennis table with only the main legs, the position of the main legs is limited to enable the folding structure, and the top plate on the side where the user plays tends to hang down. It was difficult to maintain the level and it was not stable. (B) In a foldable table tennis table with separate legs, when the distance from the end of the tabletop on the user's side to the separate legs is short and there is a feeling of pressure, or when playing in a wheelchair, etc. I couldn't play as I expected because of the legs that were set up separately. In addition, the device manufactured to solve these problems had a troublesome installation method and required a very large space for storage. It was devised to provide a product that can be easily operated.

[0004]

[Means for Solving the Problems]

 Inner folding hinges 2 and reinforcing bars 3, 3'are attached to the undersides of the left and right top plates 1, 1 '. Connecting plates 4, 4', main legs 6, 6'with casters 5, 5 ', connecting rods 7, 7'is connected to pins 8, 8 ', 9, 9'10, 10'11, 11' and 12 respectively so that each part can move freely, and can be folded in a table tennis table with a bolt 14, 14 ', a lock nut 25, 25' which is integrally molded with the rubber support tool 15, 15 'and 15, 15' that can be finely adjusted in the vertical direction, and lock nuts 25, 25 'are fixed to the horizontal rails 24, 24'. A plate attached to the connecting rails 13 and 13 'by connecting the horizontal rails 24 and 24' and the top plate supporting frames 16 and 16 'to the main legs 6 and 6', respectively. Rotated by pins 171 7'to 22, 22 ' Pins 18 and 18 'and the top plates 1 and 1', which are attached to the main plate support frames 16 and 16 'and are respectively located between the joints (A) of the top plates 1 and 1'and the main legs 6 and 6'. The pins 21 and 21 'of the plates 19 and 19' attached to the lower surface of the top plate between the joint portion (A) and the main legs 6 and 6'are connected by the interlocking rods 20 and 20 '. The present invention has a structure in which the top plate supporting device formed by the parts 14 (14 ') to 25 (25') supports the top plate on the side where the user plays from the main legs 6 and 6 '. It is a folding table tennis table with.

[0005]

[Action]

 When the ping-pong table is moved from the stored state to the used state, it has the parts (C) and (C ') in FIG. 5 and is pulled down. Then, the movement is transmitted to the pins 18, 18 'at the opposite ends of the interlocking rods 20, 20'. As a result, the top plate supporting frames 16 and 16 'start to rotate around the pins 22 and 22' and move to the movement of the top plates 1 and 1 'according to the movement of the top plates 1 and 2', and when the use state of FIG. The tops of the portions (between B and C and between B ′ and C ′ in FIG. 1) on both sides of the main legs 6 and 6 ′ are supported in a stable state by the supporters 15 and 15 ′. Further, when the storage state is changed from the use state to the storage state, the parts (C) and (C ′) of FIG. 1 are used, and the lifting operation has the same effect as when the storage state is changed to the use state. When the storage state is reached, the top plate supporting frames 16 and 16 'are compactly stored along the top plate.

[0006]

【Example】

 An embodiment of the present invention will be described below. (A) Attach the inward folding hinges 2 and the reinforcing bars 3, 3'on the lower surface of the top plate 1, 1 '. Connect with the main legs 6, 6'provided with connecting plates 4, 4'and casters 5, 5'. The rod 77 is connected by pins 8, 8 ', 9, 9', 10, 10 ', 11, 11' and 12 so that each part can move freely, and becomes a table tennis table that can be folded inward. (B) Further, plates 22 and 22 'having holes for pins formed therein are provided at arbitrary positions of the connecting bars 13 and 13' formed on the main legs 6 and 6 '. It should be noted that the connecting bars 13 and 13 'referred to here may be linear ones without being necessarily bent as shown in FIG. (C) Processing the lock nuts 25, 25 'to the cross rails 24, 24', which can fix the rotation of the rubber supports 15, 15 'and 15 15' integrally formed with the bolts 14, 14 '. Attached to the nuts 23, 23 ′ and the cross rails 24, 24 ′ configured to prevent contact with the lower surface of the top plate during operation from the stored state to the used state and from the used state to the stored state. 'And attach to the plates 22, 22' with pins 17, 17 '. The top plate supporting frames 16 and 16 'are provided with pins 18 and 18' which are rotatably mounted between the joint portions (A) of the top plates 1 and 1'and the main legs 6 and 6 '. (D) Plates 19 and 19 'having pins 21 and 21' are provided on the lower surface of the top plate between the joints (A) of the top plates 1 and 1'and the main legs 6 and 6 '. (E) Pin 21 And pin 18 and pin 21 'and pin 18' are connected by interlocking rods 20 and 20 ', respectively. The present invention has the structure as described above, and when the table tennis table is changed from the housed state of FIG. 5 to the used state of FIG. 1, it has the parts (C) and (C ′) of FIG. The pins 20 and 20 'are moved by the pins 21 and 21', and the movement is transmitted to the pins 18 and 18 'at the opposite ends of the interlocking rods 20 and 20'. As a result, the top plate supporting frames 16 and 16 'start to rotate around the pins 22 and 22' and when the top plates 1 and 1'become in use according to the movement of the top plates 1 and 1 ', they are supported. The tops of the parts outside the main legs 6 and 6 '(between B and C and between B'and C'in Fig. 1) are supported by the metal fittings 15 and 15' in a stable state, and the tops are slightly horizontal. The deviation can be adjusted by the rubber supports 15 and 15 'integrally molded with the bolts 14 and 14'. In addition, even if a user puts his / her hand on B-C or B'-C 'and it is heavy, from the pin 17 of the top plate supporting frame 16, 16' to the pin 18 and the pin 17 '. By setting the length up to 18 'and the length from pin 21 to pin 18 and from pin 21' to pin 18 'of the interlocking rods 20 and 20' to the proper length calculated, The rubber support members 15, 15 'attached to the plate support frames 16, 16' do not move downward from the positions in use in FIG. 1 and do not move downward to support the lower surface of the top plate and maintain a stable state. . In addition, when the state of use of FIG. 1 is changed to the state of storage of FIG. 5, by holding the (C) and (C ′) portions of FIG. When the storage state of FIG. 5 is reached, the top plate support frames 16 and 16 'are compactly stored along the top plate. FIG. 8 shows an embodiment in which the shapes of the support frames 16, 16 ', the connecting bars 13, 13' and the plates 22, 22 'are changed.

[0007]

[Effect of device]

 In use, since the user cannot directly see the device for supporting the tabletop on the standing side when playing, it becomes possible to play by stepping on the legs, etc., and play using the wheelchair. Sometimes there are no obstacles so you can play freely. In addition, the top plate support device of the present invention has excellent stability, can be stored compactly when stored, and its operation is extremely simple.
