Definitions

  • the present invention relates to a pre-inked stamp holder with adjustable stroke, comprising a handle, a fixed base intended to be applied to a substrate to be printed, and a stamp holder movable with said handle along an axial direction of movement, said stamp holder being, on the one hand, held in the retracted position in a cavity of said base under the action of an elastic return means, and, on the other hand, brought into contact with said substrate to be printed by displacement axial of the handle over a given stroke, against the action of said elastic return means.
  • the porous ink-impregnated print block supporting the text to be printed is neither too much nor not sufficiently compressed. If the compression is too strong, too much ink is expressed from the printing unit, so that the ink is consumed quickly and, moreover, the impression obtained is unnecessarily thick and therefore less beautiful. Conversely, if the compression is not sufficient, too little ink is expressed so that the impression obtained becomes finer and less legible. In addition, as the ink contained in the stamp is consumed, the thickness of the latter decreases which, in turn, causes that the pressure also decreases more and more, while the block d The print still contains enough ink to be able to print with an appearance of acceptable quality.
  • pre-inked stamp supports with adjustable stroke have already been proposed, conforming to the preamble, which all have the effect of adjusting the stroke of the handle, and therefore of the stamp holder, to the quantity of ink still present in the porous stamp printing block, so as to obtain the desired printing rendering for the text to be printed.
  • Some known pre-inked adjustable stroke stamp supports use a stop limiting the stroke of the handle, the position of which is adjustable along a threaded rod. Still others use an eccentric to adjust the stroke of the handle as desired.
  • the technical problem to be solved by the object of the present invention is to propose a pre-inked stamp support with adjustable stroke, of the type conforming to the preamble, which would involve a more limited number of parts and which, therefore, would be better. market and assembly easier than known supports.
  • said support also comprises a ring for adjusting the stroke of the handle having, on the one hand, a body having the shape of a cylinder of revolution of axis D parallel to said axial direction of movement, and, on the other hand, a fixed stop means for limiting the axial movement of said handle, which fixed stop means cooperates with a movable stop means provided on the handle, at least one of said stop means being constituted by a helix of revolution of axis D, and the position of said adjustment ring being adjustable in rotation about its axis D .
  • the pre-inked stamp holder of the invention consists of a reduced number of pieces, five in total. As will be seen in detail below, these parts are very easy and quick to assemble. On the other hand, with the exception of course of the elastic return means, such as a spiral spring, all the other parts of the support of the invention can be produced by simple molding of a plastic material, which reduces it substantially the cost price.
  • Figure 1 is an exploded side view of a pre-inked stamp holder with adjustable stroke, according to the invention.
  • FIG. 2 is a diagram showing how cooperation takes place between the two stop means respectively provided on the handle and on the adjustment ring.
  • FIG. 3 is a top view of the base of the support shown in FIG. 1.
  • FIG. 1 shows in exploded side view a pre-inked stamp holder with adjustable stroke, comprising a handle 10, a fixed base 20 intended to be applied to a substrate (not shown) to be printed, and a stamp holder 30 intended to receive a stamp, or porous printing block inhibited of ink carrying the text to be printed.
  • This stamp holder 30 is movable with the handle 10 to which it is rigidly connected by a central rod 11.
  • said central rod 11 forms a single piece with the handle 10.
  • the central rod is joined to the stamp holder 30 , for example, by force fitting the hollow central rod 11 on a barrel 31 fitted on the stamp holder 30.
  • the central rod 11 defines an axial direction of movement for the handle 10 and the stamp holder 30, direction parallel to the axis D shown in phantom in Figure 1.
  • the stamp holder 30 is held in the withdrawn position in a cavity 21 of the base 20 under the action of an elastic return means 40, a spiral compression spring for example.
  • This withdrawal position corresponds to the rest position of the stamp holder and the handle 10, in the absence of force exerted on said handle by the user.
  • the stamp holder 30 can be brought into contact with the substrate to be printed by axial displacement of the handle over a given stroke, under the action of a force exerted by the user against the action of the compression spring 40.
  • FIG. 1 shows that the pre-inked stamp support also comprises an adjustment ring 50 having, on the one hand, a body 51 having the shape of a cylinder of revolution of axis D parallel to the axial direction of movement of the handle 10, and, on the other hand, a stop means 52 for limiting the axial movement of the handle.
  • Said abutment means 52 is fixed relative to the base 20 and cooperates with a movable abutment means 12 provided on the handle 10.
  • the means of fixed stop 52 and movable 12 consist of two identical helixes of axis D, in head-to-tail position relative to one another and bearing against one another during the axial displacement of the handle 10 towards the adjustment ring 50.
  • the handle 10 is hollow and the propeller 12 appears as the lower edge of a relief produced on the inner lateral wall of said handle.
  • the adjustment of the stroke of the handle 10 is obtained by the fact that the position of the adjustment ring 50 is adjustable in rotation about the axis D, as indicated by the double arrow F. During its rotation, the adjustment ring is held in the axial position using a centering barrel 22 arranged on the base 20 of the stamp support.
  • Figure 2 illustrates how the adjustment of the stroke of the handle 10 can be achieved with two propellers serving as fixed and movable stop means.
  • the propellers 52 and 12 are shown in developed form.
  • the stroke of the handle 10 is determined by the double arrow a. In this position, the stroke of the handle is minimal and corresponds to a weak compression of the pad pre-inked against the substrate.
  • the maximum stroke is obtained by turning the adjusting ring always in the direction of the arrow F 'until the position defined by the double arrow b.
  • polarization means constituted, in the embodiment of FIG. 1, on the one hand, of a notch 13 formed at the end of the central rod 11, cooperating with a projecting spout 32 disposed on the barrel 31 of the stamp holder 30, in order to place the propeller 12 of the handle 10 in a determined position known for all that that the stamp holder 30 has also been placed in a determined position relative to the base 20 by means, for example, of a notch 33 formed in the stamp holder 30 and of a corresponding projecting spout 24, arranged in the cavity 21 of the base 20.
  • the barrel 22 for centering the base 20 comprises a stop stud 23, fixed relative to the propeller 12, which defines two extreme positions a, b for a stud 53 integral with the adjustment ring 50.
  • the propeller 52 of the adjusting ring is, for example, in position a of the maximum stroke indicated in FIG. 2.
  • the pin 53 is brought into position b relative to stop pin 23, corresponding to position b of maximum stroke of propeller 52 relative to propeller 12, in accordance with FIG. 2.
  • the adjustment of the stroke of the handle 10, and therefore of the stamp holder 30, is thus carried out by turning the adjusting ring 50 around its axis between the two extreme positions a and b, possibly using a knurling 54 produced on the body 51 of the adjustment ring in order to provide a good grip on said body.
  • the barrel 22 of centering comprises notching means 25 intended to temporarily hold the adjusting ring 50 in a given position, by cooperation of the stud 53 of the adjusting ring with said notching means 25.
  • FIG. 1 indicates, moreover, an advantageous arrangement of the pre-inked stamp support of the invention which resides in the fact that the adjustment ring 50 provides the additional function of seat for one end of the spiral compression spring 40, the other end of this spring bearing against the bottom of the handle 10.
  • the pre-inked stamp support has just been described by using two fixed helices for stop means, fixed and mobile. It is understood, however, that the invention could equally well be carried out with a single propeller constituting one of the stop means, fixed or mobile, the other complementary stop means being able to have the form, for example, of a single stud bearing against said propeller. It should however be noted that the embodiment of the pre-inked stamp support of the invention with two propellers offers the advantage of having a larger contact surface between the two abutment means, which guarantees less wear and greater longevity.
