Definitions

  • This invention relates to an adjustable socket or driving threaded bolts and nuts of different sizes.
  • adjustable sockets for replacing the more conventional socket set which includes a number of different size sockets for driving bolts and nuts of different sizes.
  • adjustable sockets are driven by either a ratchet wrench or a unitary wrench having a bent efnd that is received within a wrench opening.
  • adjustable sockets that are usable with straight wrenches having a handle end like a screwdriver or slidable wrench handles of the type normally used on hand taps.
  • Adjustable sockets conventionally include a plurality of jaws that are movable in a radial directicn to receive and rotatively drive nuts and bolts of different sizes.
  • the number of positions to which the jaws can be adjusted is usually great enough so that both English and metric size nuts and bolts can be driven by the socket upon appropriate adjustment.
  • a mechanic can work on any particular job with an adjustable socket without having to constantly remove one socket from the wrench and replace it with another socket.
  • the ever-constant search for a socket of a particular size is also eliminated by adjustable sockets .
  • Lucht 2,582,444 discloses an adjustable socket wherein movable jaws are mounted on a head of the socket for inward and outward movement under the control of a collar that is threaded to the head.
  • a spring moves the jaws outwardly to permit gripping of nuts or bolts of a larger size.
  • Rotation of the collar in the other direction moves the jaws inwardly by a camming action against the bias of the spring.
  • the operation of the socket involves the spring in both the opening and closing movements of the jaws.
  • French Patent 930,657 of M. Etienne Choi discloses a three jaw adjustable wrench wherein a rotatable adjusting member has three pins each of which extends outwardly in a radial direction to a hole in the associated jaw to move the jaw axially and radially with respect to the rotational axis of the wrench.
  • This type of wrench has not received any significant commercial acceptance, probably due to the fact that the pin and hole type of adjustment involved is not particularly well suited to manufacturing operations nor does such a construction provide an easily usable and effective socket with a
  • ⁇ U2STITUTE SHEET length not substantially greater than normal single size sockets. Also, this type of adjustable socket can only be used when low torque application is involved.
  • An object of the present invention is to provide an improved adjustable socket whose opening and closing movement can be performed without the need for any spring bias, which has a construction that is economical to manufacture while still being effective in operation , which is capable of applying relatively heavy torque loads comparable with one piece sockets , and which has a size small enough to make its use practical.
  • the adjustable socket of the invention includes a driver that is rotatively driven about a central axis and has a plurality of inclined slideways extending with both radial and axial components with respect to the central a is.
  • a plurality of jaws preferably three in number so as to be usable with conventional hexagonal nuts and bolts, are respectively mounted by the slideways of the driver for inward and outward movement along with concomitant axial movement with respect to the central axis .

  • An adjuster of the socket includes an annular flange that projects inwardly with respect to the central axis and is slidably received within the jaw slots.
  • Mating helical surfaces support the adjuster on the driver for adjusting rotation that moves the jaws axially and concomitantly inwardly and outwardly for size adjustment.
  • the construction and cooperation of the driver , jaws, and adjuster permit opening and closing movement of the adjustable socket without involving any spring bias and also permit economical manufacturing while still providing an extended lifetime of effective use.
  • the adjuster in the preferred construction of the adjustable socket , includes a jaw operating member on which the flange is provided and a rotatable adjusting member supported on the driver for axial movement along the central axis upon rotation thereof with respect to the driver.
  • a connection of the adjuster secures the jaw operating member and the adjusting member upon assembly of the socket and maintains the assembled relationship.
  • the jaw operating member has a sleeve construction including a first end at which the annular flange is located and a second end adjacent the adjusting member.
  • the adjusting member in the most preferred construction has an end that is press fitted into the second end of the jaw operating member to provide the connection between the members .
  • One of the members of the adjuster includes a shoulder that axially engages the other member to prevent axial movement therebetween during use of the socket.

Abstract

Une douille réglable (10) comprend un organe d'entraînement (16) possédant des surfaces de glissement inclinées (18) sur lesquelles sont montées des mâchoires (20) pouvant effectuer un mouvement de réglage vers l'intérieur et vers l'extérieur sous l'action d'un organe de réglage (24) supporté sur l'organe d'entraînement et possédant un rebord annulaire (26) pénétrant dans des fentes de mâchoires (22). L'organe de réglage (24) se compose de préférence de deux pièces, comprenant un organe d'actionnement de mâchoires (32) sur lequel est monté le rebord annulaire (26), un organe de réglage rotatif (34) supporté sur l'organe d'entraînement de manière à pouvoir effectuer un réglage par rotation, et un montage à pression (36) permettant de fixer l'organe d'actionnement de mâchoires (32) sur l'organe de réglage (34) lors de l'assemblage. Un épaulement (44) sur l'un des organes (32, 34), de préférence sur l'organe de réglage (34), s'engage axialement dans l'autre organe pour empêcher tout déplacement relatif lors de la sollicitation en charge de la douille réglable. Les fentes de mâchoires (22) et le rebord annulaire (26) s'étendent de préférence radialement sans aucune partie axiale pour empêcher tout grippage pendant le réglage et l'utilisation. Aussi bien les mâchoires (20) que les surfaces de glissement (18) où sont montées les mâchoires sur l'organe d'entraînement (16) présentent des formes arrondies dans les directions obliques du déplacement des mâchoires, et ces dernières (20) possèdent des surfaces (66) plates de serrage orientées vers l'intérieur, dont l'orientation est maintenue par l'engagement coulissant du rebord annulaire (26) dans les fentes de mâchoires (22).
