Definitions

  • This invention relates to a key device, and more particularly to an ornamental key of the type used for operating the locks of automobiles, doors or the like.
  • this invention relates to a key having decorative indicia bearing insert means iixed to the head or bow thereof characterized by ease of afiiXation of the insert onto the key head and further characterized by permanence of attachment of the insert to the head.
  • aihxed plates bearing indicia, such as monograrns, initials, or other identifying or decorative matter.
  • the plates have been secured to the key head or bow by a variety of means, including threaded fasteners, mechanical spring retainers, soldering, brazing and the like. It has also been proposed to ailix the plate to the key through the use of an adhesive bond, the present invention being directed to an improved construction of the latter sort.
  • the key has been provided with a recess or depression, the indicia bearing plate having border dimensions corresponding substantially with those of the depression, being, respectively, fastened or bonded within the depression. While reasonable permanence of attachment between the key and the plate has 'been obtained through the use of mechanical fastener means, such means greatly increase the cost of production of the device and the time required for assembling the plate with the key.
  • the present invention has for an object the provision of an improved, adhesively bonded key and plate device, eliminating the tendency experienced in bonded devices heretofore known for the plate to become dislodged after use.
  • a further object of the invention is to provide a key device of the type described including a depressed or recessed area within which the plate or insert may be positioned, which device is constructed in a manner to prevent relative movement of the plate and key upon the application of torque to the key head.
  • a further object of the invention is the provision of a device of the class described wherein the face opposite the plate carrying face presents a novel and decorative appearance.
  • Still a further object of the invention is the provision of an attractive key device which may be readily customized or personalized by the adhesive application thereto of a plate or insert carrying indicia or decorative matter.
  • a key 10 including a bow or head 11 and a shank or lock operating pontion l2?.
  • the head or bow 11 in accordance with the invention, is formed on its front face 13 with a concave or recessed portion
  • the portion 14 is outlined or delineated by walls 15, 16, 17, 18.
  • the rear face 2t) of fthe key, in an ⁇ area registering with the recessed portion 14, is provided with a raised reinforcement portion 21 which, ⁇ as shown in FIGURE 2, might take the form of an emblem, crest or other decoration.
  • the reinforcement portion 21 optionally but preferably covers substantially the entire tarea of the rear face 29 which corresponds to the area of the front face covered by .the depressed portion 14.
  • a plate or insert 30, 4 which may be flat or may, for appearance sake, be cupped or concave-convex, is secured within recess 14 by an adhesive mass or layer 3l disposed between the rear face 32 of the insert and the floor 19 of the recess 14.
  • the ⁇ adhesive or cement employed may be of any type suitable for joining the key and insert 30, both parts normally comprising metal although the use of plastic inserts is contemplated as well.
  • the plate or insert 3G may, for convenience, be precoated over its entire back portion with a stay- Wet type adhesive, such as a water insoluble rubber adhesive, the insert in such case being provided with the usual protective layer temporarily secured to the adhesive, to be removed just prior to use.
  • the outline of the insert closely conforms to the inner edges of walls 1S, d6, 17, 18, whereby the positioned insert will be engaged with such walls and will 'aid the cement layer in preventing a shifting of the insert.
  • the overall depth of the insert 30' is such that together with the thickness of the adhesive layer 31, the outer edge of the insert does not project beyond the face 13 of the key.
  • FIGURE 3 there is shown in solid lines a sectional View of a key in accordance with the invention.
  • FIGURE 4 la similar View is shown of a prior art key.
  • the dot and dash lines in each of FIGURES 3 and 4 represent, on a somewhat exaggerated scale, the conigurationsV of the keys upon application of ⁇ torque to the key bow, with some resistance to turning of plug P of lock cylinder assembly C being assumed.
  • the torsional stresses ⁇ and strains herein referred to are limited to the head of the key since the shank of the key is received within and maintained in aligned condition by the keyway slot of the plug P.
  • the reinforced area of the key of the invention effec ⁇ vide on said bow portion an area having substantial re-.
  • the above described key device provides a durable, inexpensive and attractive customized article.
  • Va durable and permanent cemented connection between the key and the plate or inesrt is obtained, a feature not found in cornparable key devices heretofore known.
  • the reinforcing portion in addition to performing the functions aforesaid, enhances the appearance of the key.
  • the floor T19 of the recess V may be stamped with a marking 19a which corresponds with or identities the keyway section of 'the key to facilitate selection of the ⁇ proper key by the key cutter and at the same time provides a roughened surface to augment the effectiveness of the adhesive bond.
  • the described decorative key device is supplied to the locksmith or other key cutter along with plates marked with numerals or other indicia.
  • the locksmith then cuts or bits the key shank in known manner to correspond with the hitting or pattern of the key supplied by the customer.
  • the insert or inserts bearing the selected initial or indicia are then mounted in the recess of the key either by application of cement to the rear face of the plate or in the recess or, in the case of an adhesive bearing insert, by stripping the protective layer from the back of the insert and pressing the insert into the recess.
  • an alloying material of the kind which does not ⁇ sacrifice rigidity and long wear and which is susceptible of accurate formation by forging without limitation, an additional feature which may prolong the utility of the union between the emblem 30 and the key bow, during its course of use, even to the point of rigidity of union of the insert or emblem '310v within the seat or recess 14 by a friction tit about its periphery to augment or even substitute for the adhesive union.
  • An ornamental key comprising a shank portion and a bow portion, said bow portion being formed to define a recessed area on one face thereof, the other face of said ibow portion including a raised reinforcing portion substantially in registry with the recess of said one face and extending outwardly beyond said other face to provide on said bow portion an area having substantial resistance to deformation under torsionalV stress, independent inse-rt means positioned within said recess and having outer marginal edge portions conforming substantiallyY to the outline of said recess and an adhesive layer interposedY between said recess Iand said insert means and bonding said'means to said key, all portions of said insert means lying within said recess and beneath the plane of said one face, whereby said recessed area will be substantially unaffected by torsional stresses applied to said bow to minimize relative movement of said insert with respect to said ICCGSS.
  • concave area and spanning an larea on said other face substantially coex-tensive with said concave area, to prosistance to deformation under torsional stress
  • independent insert means positioned within said concave area and having outer marginal edge portions conforming substantially v to the outline of said last named area, and an adhesive layer interposed between said insert and portions of said concave area and bonding said insert within said area, all portions of said insert means lying within said concave area and beneath -the plane of said one face, whereby said concave tarea will be substantially unaiected by torsional stresses applied to said bow to minimize relative movement of said insert with respect to said key.
  • said raised reinforcing area includes a coined decorative emblem on the outer face thereof.
  • An ornament-a1 key blank comprising ya shank and a bow portion, said bow pontion being formed to define a recessed area on one face, the other face of said bow 10 including a raised reinforcing portion substantially in registry with the reoess of said one face, and extending outwardly beyond said face to provide on said bow an area having substantial resistance to deformation under torsional stress, whereby independently attachable insert 15 2,781,594
