Definitions

  • the present invention improves the gut hole of the racket in two ways, makes it easier to stretch the gut, and improves the hitting performance.
  • One meaning of the improvement is to make the size of the gut holes larger than the size of approximately three gats, with the upper limit being the diameter of the gat mesh diameter. .
  • the side surface of the hole is formed as a discontinuous surface with frame components.
  • a part that comes into contact with the gut comes into contact with the gut, it must be formed as a continuous surface and be formed with a curved surface such as a saddle so that the bent part does not appear in the gut that comes into contact with the frame.
  • the inside of the frame through which the gut penetrated was a space, so to speak, two small holes were made in the upper and lower plates, and the gut passed through it. And the gut tension was held only by the plate on the outer periphery of the frame called the “shelf".
  • the gut bends almost at right angles to the frame, and stress concentrates on the side of the frame at this bend, causing breakage and collapse of frame components called so-called “shelf drop". Easy to do.
  • the thickness of the top surface of the frame was necessary, which also hindered the quantification to some extent.
  • the conventional structure of the gut hole is a small hole formed in the upper and lower two plates.
  • the gut tension tends to concentrate on the upper surface of the frame, and the lower surface of the frame not only serves to prevent the gap from shifting, but also reduces the hitting performance.
  • the conventional gut hole has an upper limit of the diameter of only about three guts, and tightly fixes the gut to the frame. When fixed in this way, when hitting near the frame, the near-frame force is at a sharp angle with the frame, and excessive stress is concentrated on the short gut on the lower side of the frame. However, gut breakage was inevitable.
  • An object of the present invention is to eliminate all the drawbacks of the conventional gut hole described in the present invention. Disclosure of the invention
  • the structural features of the gut hole of the present invention are the three disclosed below. 1) “The gut hole is large enough to be molded integrally with the frame.” The portion of the gat hole near the outermost periphery of the frame is twice the width of the maximum gat mesh in the longitudinal direction of the frame. At the outermost periphery of the frame, the minimum is the size of the conventional gut hole and the maximum is the width of the gut mesh.
  • the gut hole is not formed later, but is formed integrally with the frame at the time of molding.
  • the portion of the frame where the frame and the gat are in contact is formed as a curved surface by the frame components, and does not form a corner that bends the gut. Therefore, between the two adjacent gut holes
  • the frame portion in the above forms a saddle portion, and the cross section of the hole in the frame longitudinal direction is a funnel-shaped and its size changes when viewed up and down. In these frames, the gut tension is well distributed on the surface of the frame.
  • the gutter hole's perimeter is the length of the gut mesh in the frame's longitudinal direction at the frame's perimeter.
  • the gut hole and the other portion face each other. This is similar to a configuration in which two legs of the same ladder are staggered facing each other, and a gut surface is formed by stretching a gut on that stage.
  • FIG. 1 shows an embodiment in which the number of gut holes is maximized, and the length of the gut holes in the longitudinal direction of the frame at the inner periphery of the frame ft is equal to the gut mesh.
  • the width of the funnel-shaped gut hole at the outermost periphery of the frame is twice the width of the gut mesh.
  • FIG. 2 is a side view of the embodiment of FIG. You can see that the gut is curved at all, not at the frame.
  • FIG. 3 shows the arrangement of the gut holes in the frame facing portion.
  • the gutter holes are not drilled in a one-to-one correspondence like the conventional force-gear holes: the opposite sides of the frame have gutters, gutter holes and frame gutters. Frame and force; one-to-one correspondence.
  • FIG. 4 is a cross-sectional view at the center of the gut hole of FIG.
  • the gutter hole at the top of the frame is also large enough, the force catch is loosely fixed to the frame and has a large movable range.
  • the best embodiment is, as it were, a configuration in which a number of small pipes serving as gut suspension parts are passed over two pipe frames.
  • the gut hole is the surface of the frame, and the frame portion forming the hole bears the overall strength. Therefore, except for the part that directly receives the gut, the frame thickness is formed sufficiently thin to reduce the weight.
  • gutter holes are integrally molded with the frame, eliminating any secondary work on the gutter holes.

Abstract

Dans une raquette, les trous pour les cordes sont suffisamment grands pour que l'on puisse y introduire un doigt, ce qui rend superflus des passe-fils. En même temps, la résistance du cadre de la raquette est augmentée par une surface continue qui constitue la surface latérale des trous. On peut ainsi corder plus facilement la raquette et améliorer sa performance de frappe, étant donné que la plage dans laquelle les cordes peuvent se déplacer à proximité du cadre est plus grande. Selon l'invention, les trous adjacents pour les cordes d'une raquette classique sont intégrés dans un grand trou. Les trous pour les cordes ne sont pas agencés en vis-à-vis, comme dans les raquettes classiques, mais sont décalés d'une maille des cordes. Par conséquent, la raquette a environ la moitié de trous pour les cordes qu'une raquette classique. En outre, les trous sont ménagés dans une surface continue de l'organe constitutif du cadre.
