Definitions

  • Anobject of this invention is to provide a parking brake operating lever which can be automatically assembled.
  • the lever proper is divided lengthwise for these purposes.
  • FIG. 1 is a vertical cross section
  • FIG. 2 is an end view taken from the right of FIG. 1;
  • FIG. 3 is a view of the major component parts
  • FIG. 4 is an exploded perspective showing several principle components.
  • the numeral'l indicates a parking brake operating assembly of this invention.
  • the assembly includes a cylindrical portion 3 having at one end a downwardly extending triangular-shaped base portion 2.
  • the lever assembly is divided longitudinally into symmetricalparts a and b.
  • the base 2 is apertured at its lower end to receive a braking cable to perform a braking function in the conventional manner.
  • Extending inwardly from portion a are a pair of pins 4 and 5 reduced in diameter at their outer ends to be received by matching apertures in the base portion 2 of part b.
  • a ratchet fitting 9 notched at area 10 is secured to the vehicle chassis c by bolts as shown in FIG. 1.
  • a pawl member 11 mounted for pivotal movementabout pin 5 and having a tooth for engagement with the ratchet portion 10.
  • the pawl 11 is pivotally secured to a rod 8 having a button 13 at its outer end.
  • a handle member 12 of plastic or rubber is secured about the cylindrical portion 3.
  • a coil spring 7 is disposed between the abutment l4 and the button 13 and acts to bias the pawl into engagement with the ratchet.
  • a depression of the button 13 against the bias of the spring permits the pawl to disengage the ratchet portion.
  • the lever assembly itself is mounted for pivotal movement about pin 4 when the ratchet is disengaged. As will be readily understood by those skilled in the art, a pivoting movement of lever 3 when the pawl is disengaged will permit the base portion 2 to transmit a braking or release movement to a cable attached thereto.
  • This brake assembly is generally referred to by the numeral 6.
  • I numeral 15 indicates a tubular cover which encloses the cylindrical portion 3 by sliding it from the front after joining side b to the receiving side a of said lever from the identical side with said braking mechanism 6 and clamping and securing the tip portions of said pivot pins 4, 5 which protrude from the surface of the base portion.
  • the tube covers the joint which is unfavorable to the vehicle standard as it is exposed in the longitudinal direction of the upper portion of said lever proper l, and retains the joint between said receiving side a and the joint portion side b more firmly to prevent a decrease in strength.
  • the brake operating lever is generally coated with a chrome plating giving the lever of this invention an effect similar to an expensive chrome plating by making it with a stainless steel sheet.
  • the covering method may be carried out either by bending projecting members provided at the appropriate end portions inwardly of the lever proper l, forming the lever by an elastic material and clamping from the external side, or applying a bonding. agent on an inner periphery to bind them.
  • the numeral 12 indicates a handle grip which is inserted with pressure from the forward portion into the tip portion of the cylindrical portion 3, and is effective in retaining the joining of said receiving side a and the joint portion side a b more firmly, but it may not be used when the cover'l5 encloses the cylindrical portion.
  • the pivot pins 4 and 5 can be fixed to the side b or the fitting member 9 of the braking mechanism 6 without rising andfixing to the one of the receiving sides a of the lever proper I, or can be inserted from its oneside after jointing the side b to the side a without fixing to either side.
  • a divided lever this invention enables the assembly of the component parts, namely, the fitting member 9 the braking mechanism 6, the operating lever 8, and the divided lever proper l to the other divided portionv by supplying them from the identical direction. This makes the automation of the assembly of parts of said operating lever.
  • the operating lever of this invention can be applied to the braking mechanism 6 which is an important portion ofthe lever to a wide range not only for the above-mentioned ratchet system but also for a wedge system.
  • said first means includes a pin extending between said first and second sides.
