Definitions

  • the manufacturing method of the present invention includes a mold cavity for forming a grip for tools, a core space in which a core is disposed in the mold cavity, and two types of resin are injected into the mold cavity.
  • the mold cavity outer surface force, and a plurality of pins are arranged toward the core space.
  • the first resin is injected and injected from the inlet.
  • a bridging portion connecting the grip inner and outer layers is formed around the pin, and then the second resin is injected and injected from the inlet.
  • an elastic layer is formed so as to surround the bridge portion between the inner and outer layers of the grip.
  • the core 2 is made of a resin having a higher melting point and harder than the resin constituting the grip member 3.
  • polypropylene, nylon, ABS, etc. are used for the resin constituting the core 2.
  • the position where the sub-bridge portion 3D is arranged can be coarsely and densely arranged in the longitudinal direction and the Z or circumferential direction of the grip 1, and is arranged at a dense pitch particularly in a portion where the transmission torque from the grip handshake is large.
  • the parts having a small transmission torque are arranged at a rough pitch (for example, appropriately set within a range of 5 to 20 mm).
  • the grip 1 of the second embodiment when the grip outer layer 3B and the elastic layer 4 are deformed radially inward by the compression force from the radially outer side, the second sub-crosslinking portions 3D2, 3D2
  • the tip end of the rod-like protrusion 3E in between is in contact with the outer surface of the grip inner layer 3A, and further elastic deformation of the grip outer layer 3B is suppressed or prevented.
  • the first sub-crosslinking portion 3D1 may be formed.
  • Each embodiment of the present invention also has the above-described configuration force. According to the configuration shown in these embodiments, the outer surface is indented and deformed by the finger pressing force, and the contact area is increased. Rotating torque that is familiar to fingers and easy to grasp can be efficiently transmitted from the grip member 3 to the handle S of the tool.
  • the grip 1 is cushioned to reduce hand fatigue and increase rotational torque transmission efficiency.
  • the elastic layer 4 may be provided between the grip inner layer 3A and the grip outer layer 3B.
  • the elastic layer 4 is sufficiently compressed and deformed in the circumferential direction of the grip, and torque is not transmitted to the core 2 unless it is force. Therefore, torque transmission loss increases.
  • the previously injected resin is diffused by each pin 10 and flows and fills every corner of the mold cavity 11, and adheres to the periphery of each pin 10 and solidifies, and the sub-crosslinking portion. 3D will be scattered.
  • a cross-linking portion (main cross-linking portion) 3C continuous in the longitudinal direction is formed at a location far from each of the injection ports 13.
  • An intermittent portion (interrupted portion of the main bridge portion) in which the elastic layer 4 is filled is formed.
  • the elastic layer 4 fills the gap between the grip inner and outer layers 3A and 3B and between the main cross-linking portion 3C, the first sub-cross-linking portion 3D1, and the second sub-cross-linking portion 3D2 connecting them.

Abstract

La présente invention concerne une poignée destinée à un outil, ou autre élément semblable, qui est facile à saisir et augmente l'efficacité de transmission d'un couple de rotation d'une main ou de doigts à un outil, ou autre élément semblable. La poignée comprend un noyau (2) fixé sur un manche d'outil, des éléments de préhension (3), fixés sur la périphérie externe du noyau (2) et possédant chacun une structure double couche pourvue de couches de préhension interne (3A) et externe (3B), et une couche élastique (4) disposée entre les couches de préhension interne (3A) et externe (3B) et permettant à la couche de préhension externe (3B) de se déformer lorsque la poignée est saisie par une main. Des sections pont (3C, 3D) sont installées sur de multiples positions dans les directions circonférentielles et longitudinales de la poignée, incorporées aux couches de préhension internes (3A) et font radialement saillie depuis les couches de préhension externes (3A). La couche élastique (4) est formée entre les sections pont et une couche de préhension externe (3B) est obtenue entre les extrémités des sections pont.
