折畳み式卓球台における後脚軸枢着部の改良に関するも
のである。[Detailed description of the invention] This invention is a foldable table tennis table that is equipped with a pair of front and rear legs, and when folded, the tabletop surface is inward and the front and rear legs are folded outward. This invention relates to improvement of the shaft attachment part.

従来、上記折畳み式の卓球台においては、その折畳みの

持しつつ天板の端部を持ち上げて左右の天板を折畳むも
のである。Conventionally, when folding the above-mentioned folding table tennis table, the left and right top plates are separated by lifting the ends of the top plate while grasping the upper parts of the rear legs that are pivoted to the crosspieces on the back of the top plate. It is foldable.

しかしながら、この場合、天板自体にかなりの重量があ

あった。However, in this case, coupled with the fact that the top plate itself has considerable weight, when both ends of the top plate are lifted up to a certain height, the rain top plate will naturally move as if in continuous movement. If you continue to hold the upper part of the hind legs with your hand, your fingers may get caught between the hind legs and the top plate to which the hind legs are pivoted. There was a problem in that an unexpected accident such as cutting the wire could occur.

このような従来の実情に鑑み、本考案は上記の如く事故
を回避し、如何なる状況においても全く安全に卓球台を

供することにある。In view of these conventional circumstances, the present invention is designed to avoid accidents as described above and to allow the table tennis table to be folded completely safely under any circumstances. To provide a folding table tennis table with an improved leg pivot joint.

以下、図面に従って本考案の改良を具体的に説明する。Hereinafter, improvements of the present invention will be specifically explained with reference to the drawings.

着するように構成した折畳み式卓球台における後脚軸枢
着部の改良である。The pivot joint part A of the rear leg 3, which is pivotally connected to the crosspiece 2 of the L-shaped metal fitting fixed to both sides of the back surface of the left and right top plate 1, is connected to a thick tube body 4 and a hard rubber material of an appropriate thickness made of a hard rubber material. The tube bodies 4 and the hard elastic bodies 5 which are alternately arranged are placed in a lying position such that the distance between the hind legs and the crosspiece is wider than the thickness of a human hand. Improvement of the rear leg pivoting part in a folding table tennis table configured to fit into a bolt 6, insert the bolt into the upper end opening 7 of the rear leg 3, and tighten the entire table with a nut 8. It is.

このようにして枢着された該軸枢着部Ａは、硬質弾性体
５と肉厚の管体４とが交互に配置されているので、適当
なる弾性を保持しつつも後脚３は桟２に強く枢着される

体が充分に入るだけの間隔が開けられている。The pivot attachment part A pivotably attached in this manner has hard elastic bodies 5 and thick tube bodies 4 arranged alternately, so that the rear legs 3 can be attached to the crosspiece while maintaining appropriate elasticity. 2, and there is a gap between the rear legs 3 and the crosspiece 2 that is large enough to accommodate the entire thickness of a human hand.

されることになる。Therefore, in a folding table tennis table that is folded with the top surface inward and the front and rear legs outward, when folding the table tennis table, hold the portion of the back leg 3 near the pivot point and hold the table tennis table. Even if the end is lifted and the left and right rain plates move naturally and continuously due to their weight, the fingers gripping the hind legs are completely safe due to the sufficient distance between the pillar 2 and the hind legs 3. will be protected.

何なる折畳み状態で後脚の上部を手で把持していても手
をはさむ等の事故を完全に回避することができる。That is, when the left and right ends of the top plate are pushed up and moved to a considerable height, the crosspieces 2 and the upper parts of the rear legs 3, which are fixed to the top plate, approach each other and are folded. As mentioned above, in the conventional case, accidents such as a hand being caught between the approaching crosspiece 2 and the upper part of the hind leg 3 would occur, resulting in a finger being severed. In the above-mentioned present invention, the crosspiece 2 and the rear legs 3 can be folded together without interfering with the folding function.
Since there is a sufficient distance between the rear legs and the pivot attachment part A, accidents such as getting your hands caught can be completely avoided even if you hold the upper part of the rear leg with your hand in any folded state.

できる。At the same time, the pivot attachment part A is made up of hard elastic bodies made of hard rubber material and tube bodies arranged alternately, so that the folding function of the table tennis table becomes smoother and when used as a table tennis table, the table Even if an unexpected force is applied from the left or right side of the table, this is buffered by the above-mentioned shaft attachment part, preventing the alloy body from rolling, thereby providing a new effect on the table tennis table to prevent rolling collisions. You can also do that.

改良である。As mentioned above, the present invention is a folding table tennis table that can be folded with the top surface inward, and can be folded completely safely under any circumstances, thereby protecting the human body. This is an improvement to the rear leg pivot point in a table tennis table.
