Definitions

  • ABSTRACT A pawl is coaxially mounted on the shafi of a control button with which it is angularly interlocked but with an angular play.
  • a spring selectively urges the pawl either towards an operative position in engagement with a ratchet or an inoperative position spaced from the ratchet, selection taking place by turning the control button.
  • the ratchet can turn in one direction which oscillates the pawl through an angle smaller than its angular play with the control button which is therefore not caused to oscillate.
  • the shaft can be loosely mounted on a support with an elastorncric packing member to take up play and ensure fluidtightness; similarly, the pawl can be loosely mounted on the shaft so that when the pawl locks the ratchet, the pawl is pressed against a supporting surface thereby avoiding strain on the shaft.
  • Releasable pawl and ratchet mechanisms are known, for example for fishing reels.
  • the pawl when in an operative position, allows rotation of the ratchet in only one direction but can be moved into an inoperative position, in which it allows rotation of the ratchet in both directions, by means of a control member generally fixed to the pawl and protruding outside a casing which houses the pawl and ratchet mechanism.
  • control member is caused to vibrate when the ratchet is rotated with the pawl in operative position, which is unsightly and often inconvenient.
  • control member generally requires provision of an oblong aperture in the casing so that the device is not watertight.
  • a certain well known type of releasable pawl and ratchet mechanism obviates these drawbacks in an efficient manner, but the device is costly.
  • a push-button, lever, stud or other control member is located outside the casing and operates a cam which in turn can move the pawl by means of a shafi passing through the casing.
  • the pawl and the control member must each have a return spring, which adds to the cost.
  • Another object of the invention is to provide a releasable pawl and ratchet device which stands up well to wear and, in particular, in which wear on the pivoting shaft of the pawl is avoided.
  • An additional object is to provide a releasable pawl and ratchet device which can be simply dismantled, and mounted and in which the direction of rotation of the ratchet can, if desired, be reversed.
  • a releasable pawl and ratchet device comprising control means coaxially mounted with the pawl for pivoting the pawl between 'an operative position in engagement with the ratchet and an inoperative position spaced from the ratchet, and a spring selectively urging the pawl either towards the operative position or the inoperative position, wherein the control means and the pawl are angularly interlocked with an angular play at least as great as the angular excursion of the pawl caused by rotation of the ratchet whilst the pawl is in the operative position.
  • FIG. 1 is a partially cut-away side view of a device according to the invention
  • FIG. 2 is a cross-section along line A-'A of FIG. 1;
  • FIG. 3 is a schematic side view of a control button for the device of FIGS. 1 and 2;
  • FIG. 4 is a cross-section along line A-A of FIG. 3;
  • the pawl 1 is held on button 2 by a washer 6 removably fixed to the ratchet 6a.
  • FIGS. 5 and 6 are schematic views of part of the housing of pass through the aperture 50 so that the button 2 cannot unwantedly fall out of the housing 5.
  • buttons 2 Play in the mounting of button 2 is taken up by an elastic washer 4 in cellular plastics material or an elastomer which also ensures watertightness of the joint which is important, for example, when the device is incorporated in a fishing reel.
  • a blade spring 3 (see FIGS. 7 to 12) is bowed between a notch la on the pawl l and a notch 9a in a stud 9 on the casing 5 so that the pawl is urged either towards a first position in which it abuts the stop, 7 (FIG. 7) or towards a second position in which it operatively engages the ratchet 6a (FIG. 8); in between these two positions, the spring 3 has an unstable equilibrium position when the center of the shaft 20, the notch la and the notch lb are in line so that the pawl I can be selectively moved between the first and second positions by turning button 2.
  • the ratchet With the pawl in this second position, the ratchet can rotate in the counter-clockwise direction as indicated by arrow Fl (FIG. 9).
  • the teeth thereof cause the pawl to intermittently oscillate through an angle 01,, the pawl being permanently urged in the counter-clockwise direction by spring 3.
  • the first tooth of the ratchet that lifts the pawl also caus'es displacement of the control button 2 through an angle a, by action of the surface 1b of the pawl on the surface 2f. Whilst the pawl is returned to its original position between two teeth I by action of the spring 3 the control button remains in the position of F IG 9 during further rotation of the ratchet. It can thus be seen that during rotation of the ratchet in the direction of arrow Fl the control button will not be caused to vibrate or oscillate.
  • button 2 could be in metal.
  • the button comprises two quadrant-shaped projections 2b and 2c of different thickness projecting from a shaft 2a.
  • the housing 5 is provided with an aperture 5a (FIG. 6) shaped to allow projections 2b and 20 to freely pass therethrough so that button 2 can be mounted on the housing 5 with a knurled head portion located outside the housing and the projections 2b and 2c inside.
  • the pawl 1 is freely mounted with angular play (see FIG. 1) on the end of shaft 20 adjacent the projection 20 so that the pawl can be angularly. moved by turning the knurled part of button 2.
  • the pawl also has a certain diametral play, the purpose of which will be described further on.
  • the pawl can be released from the ratchet by turning the button 2 in the direction F3, as indicated in FIG. 1 l.
  • the surface 23 of the button is freely turned until it comes into contact with the surface 1c of the pawl; at most, the butcontacts the pawl. Then, against action of the spring 3, the
  • Tl-Ie direction of rotation of the ratchet when the pawl is operating, can easily be reversed in the described device, as is indicated'in FIG. 12.
  • a second stop 7a and a second stud 10' are provided on the other side of button 8 to the stop 7 and stud 10.
  • the pawl 1 is placed on button 2 facing in the other direction to that shown in FIG. 1 and FIGS. 7 to 11 and the operates in an exactly similar manner to before, apart from the allowed direction of rotation of the ratchet 6a when the pawl is in the operative position.
  • the device can be assembled and dismantled without the need for special tools and without difiiculty. It is particularly suitable for use in fishing reels, but this use is given solely by way of example.
  • a releasable pawl and ratchet device comprising a pawl pivotally mounted for operative engagement with a rotatable toothed ratchet and control means rotatably mounted coaxially with the pawl for pivoting the pawl between an operative position in engagement with the ratchet and an inoperative position spaced from the ratchet, and a spring selectively urging the pawl either towards the operative position or the inoperative position, the pawl when in the operative position allowing rotation of the ratchet in one direction which causes oscillation of the pawl by the ratchet with a given angular excursion of the pawl, said control means comprising a shaft and said pawl being pivotally rotatable around said shaft, the control means and the pawl being angularly interconnected for angular movement of said pawl selectively from operative position to inoperative position and from inoperative position to operative position by angular movement of said control means, the
