Definitions

  • the invention aims to create an appliance of this nature which shall be particularly simple, and cheap to manufacture, while on the other hand it ensures efiective working of the appliance.
  • the operating means according to the invention for writing appliances with retractable writing elements such as ball-point pens, having a casing in which the retractable Writing element is resiliently urged towards a push button, comprises a flat push rod connected to the push button by a flexible connector, the lower end of the push rod having two laterally spaced apart lugs separated by a central recess, and the push rod having a hook on one of its sides adjacent to one of the said lugs, fixed bosses being pro vided on the casing at opposite sides of the push rod so as to laterally displace the top of the writing element which is resiliently urged so as to bring it in alternate engagement with one or the other of the said two lugs of the push rod so as to deform the flexible connector in order to engage or disengage the hook with respect to a fixed complementary member on the casing each time the push button is operated.
  • one of the essential characteristics of the invention is to bring to bear on the flat pushrod a rotating or rocking torque which tends to make it swing transversally in one direction or the other, under the action of the pressure of the customary return-spring of the cartridge of the Writing device.
  • FIGURE 1 is an axial section through the operating means showing the writing element in the retracted position
  • FIGURE 2 is a bottom plan view of the means shown in FIGURE 1,
  • FIGURE 3 is a view similar to FIGURE 1, but showing an intermediate position of the parts during projection of the writing element
  • FIGURE 4 is a view similar to FIGURE 1, but showing the parts with the writing element in its writing or projected position,
  • FIGURE 5 is a view similar to FIGURE 4, but showing ice the parts when a manipulating button has been depressed to retract the writing element, and
  • FIGURE 6 shows the parts with the writing element in retracted position and when the button has been released.
  • the parts illustrated comprise the upper part of a ball-point pen with a retractable writing element.
  • This pen includes principally a cartridge A, of known type, which a spring (not shown) presses constantly upwards in the direction shown by the arrow 1.
  • the cartridge A consists of a plastic tube containing a viscous ink and its flexibility is dependent on to laterally displace the top of the cartridge A inside the pen during the different working phases of the device.
  • This device includes essentially a cylindrical case B and a push button C which is attached by a flexible component D to a flat push-rod E.
  • the assembly CD-E is made in one piece of a plastic material.
  • the button C is cylindrical and it has on one side a longitudinal groove 2, in which a radial nipple 3 engages, same projecting into the interior of the case B, in order to limit the longitudinal sliding movements of the push button C.
  • case B For assembly one must rely on the elastic flexibility of the case B, which may be flattened or made oval temporarily while the nipple 3 is being engaged in the groove 2, until the nipple 3 snaps into the groove 2. The reverse deformation of case B is then impossible when the case B is itself pressed lightly into the upper part of the pen, which is not shown.
  • the flexible component D is made in a sinuous shape, formed by two transverse notches 4 and 5 arranged so as to be staggered.
  • the push button C being cylindrical and solid, behaves like a rigid body, while the flexible component D and the push-rod E are flat (FIGURE 2).
  • the component D may be deformed when the push-rod E is caused to swing sideways towards the left (FIGURES 3 and 4) or towards the right (FIGURE 5).
  • the push-rod E has a generally rectangular shape in which its width is closely equal to the internal diameter of the case B.
  • the bottom of this push-rod includes two lateral lugs 6 and 7 which are separated by a central depression 8.
  • the vertical side of the push-rod E situated above the lug 6 is deeply cut out so as to form a hook 9, pointing upwards and provided with an inclined engagement face 10.
  • the thickness 11 of the pushrod is less than the diameter 12 of the cartridge A (FIG- URES 1 and 2).
  • the case B is provided at its lower end with two diametrically opposed slots 13 and 14 the width of which is closely equal to the thickness 11 of the push-rod E with little play.
  • the upper part of the slot 13 is terminated by an inclined face 15 which flares out upwardly in the direction of the outside of the case B. This inclined face 15 is thus directed in the same direction as the face 10 of the hook 9.
  • the bosses 16 are displaced in an axial direction in relation to the bosses 18 which are situated at a higher level opposite that of the face 15.
  • the top a of the cartridge A is preferably rounded to facilitate its transfer from one to the other of the lugs 6 and 7 as will be described.
  • the device according to the invention appears as in the positionillustrated in FIGURE 1.
  • the top of the cartridge A comes into contact with the inclined face 17 of the bosses 16, and the rising of the cartridge A is therefore accompanied by a displacement of its top in a direction opposite to that of the arrow 20, which has the eflect of transferring the top of cartridge A onto the right lug 7.
  • the ball-point pen is then ready to be used for writing.
  • the framework of the invention would not be exceeded by manufacturing the flexible element D in any shape whatever, or by using three separate components C, D, E assembled together instead of being made in a single piece.
  • An operating device for writing appliances with re tractable writing elements comprising a casing, a Writing element resiliently urged towards a retracted position, a push button for displacing said writing element against the action of resilient means, a flat push rod, flexible connecting means between said push button and said flat push rod, two laterally spaced lugs on the bottom of said push rod separated by a central depression, a hook on one side of said push rod adjacent one of said lugs, a complementary formation on said casing for engagement by said hook, and fixed bosses on the casing at opposite sides of said push rod for en gaging with and laterally displacing the top of the writing element to bring the top of said writing element into alternate engagement with said lugs on said push rod and deform said flexible connecting means to engage and disengage said hook with said complementary formation when said push button is actuated; one of said fixed bosses being disposed opposite to and at the same level as said complementary formation and the other of said fixed bosses being disposed at
  • each of said fixed bosses is comprised of a pair of spaced apart fixed bosses adapted to 'slidably receive said flat push rod therebetween, each boss having a lower face inclined upwardly in the direction toward the center of said casing.
