US 5,377,599 A · Adjustable mount device for pre-inked hand stamp

Abstract

In a hand stamp mount device especially suitable for a preinked stamp impression member that can give great numbers of imprints, the downstroke distance of a substantially rigid, non-rotatable assembly of a handle, a stem and a platen for carrying the impression member is adjustable precisely by turning with one's fingers an adjuster that correspondingly turns a stroke limiting stop member and causes it upon turning to be displaced proportionately lengthwise of the stem. Several ways of effecting the adjustments are disclosed, including some which eliminate all need for screw-threaded parts by making use of a molded ramp member presenting helical ramp surfaces. The platen and a case enclosing it are stiffened to resist stamping forces by an array of integral radiating ribs protruding upwardly from the platen and another array of such ribs protruding downward from the top of the case; and the ribs of the two sets intercalate to occupy vertical space in common when the platen is in normal upward position. A cover closing the case presents structures which limit downward movement of the platen, and structures connecting the cover with the case resist removal of the cover otherwise than by force applied to an end thereof. Further, the handle of the device is provided with an asymmetrically rounded knob form enabling reliance on the feel of it in a user's hand for securing right-reading stamped imprints.

a stop member constituted by a part of said assembly inside said handle and a coacting stop member constituted by a structure normally held seated relative to an upper portion of said case, said stop members being spaced apart in said upward position of said assembly and upon downward displacement of said assembly abutting each other to stop such displacement, one of said stop members being adjustable in location lengthwise of said stem to change the permitted distance of such displacement;
an adjuster turnable about said stem and having an upper portion that peripherally surrounds said one stop member and upon turning of said adjuster correspondingly turns said one stop member about said stem;
and means responsive to such turning for substantially proportionately displacing said one stop member lengthwise of said stem;
said stem having an intermediate portion thereof formed with an external thread extending spirally thereabout and therealong, said one stop member being an internally threaded nut turnable about and along said stem on said thread;
said platen being a molded body of hard resilient material comprising a panel thereof sufficiently large in area to cover a said impression member and having a stem-holding portion joined to the lower end of said stem, said panel being formed integrally with ribs protruding upward from its upper side and substantially radiating from said stem-holding portion over substantially the area of said panel to stiffen the platen against deformation by force applied to it through said stem;
said case being a molded body of hard resilient material comprising a top wall thereof adapted to overlie said platen in close proximity thereto when said assembly is in its said upward position, said top wall having a sleeve portion to receive said stem-holding portion of said platen, and being formed integrally with ribs protruding downward from its under side and substantially radiating from said sleeve portion over substantially the area of said top wall to stiffen said case against deformation by force applied to it through said assembly;
said ribs of said top wall of said case extending along locations spaced from the locations of said ribs of said platen panel so that in said upward position of said platen the radiating ribs of the respective sets thereof are disposed horizontally side-by-side and occupy vertical space in common without substantially contacting one another;
said case top wall being formed integrally with opposite side panels and opposite end panels, which panels surround said platen about an open lower side of said case to bear on a surface to be marked;
and a cover to close said lower side, said cover comprising a bottom panel formed integrally with upstanding opposite side flanges and opposite end flanges, which flanges respectively fit inside respective marginal portions of said side panels and end panels;
said flanges having portions thereof standing inward and upward sufficiently that when said cover is in place said standing portions lie in the path of and will obstruct downward movement of said platen to prevent said impression member from being pressed against the inner surface of said case;
said opposite side flanges each having a narrow elongate beading protruding laterally from it along an intermediate portion of its length, and said marginal portions of said opposite side panels each having a narrow groove formed therein along an intermediate portion of its length to receive and interlock with one of said beading, said beadings when seated in said grooves resisting removal of said cover from said case by downward force of said platen against said cover yet enabling such removal by modest downward force applied to an end of said cover and thus acting angularly on said beadings;
said handle comprising a knob having a front portion rounded to fit into the palm of a user's hand and having an asymmetric rounded portion protruding backward for being grasped in fingers of the hand;
said platen, said stem and said handle being rigidly interconnected in a fixed relative orientation with said asymmetric portion of said knob protruding in a direction away from the front of the stamp mount such that by the feel of said knob in one's hand said platen may be oriented reliably for stamping right-reading imprints of an impression member mounted on the platen.
