Definitions

  • a cylinder lock and key wherein an inner cylinder is rotatable within an outer cylinder; the outer cylinder has one or more rows of tumbler pin bores extending longitudinally of the axes of the cylinders with each row lying in a common plane and with additional rows of tumbler pin bores extending longitudinally of the axes of the cylinders and lying in planes inclined with respect to said common plane; the inner cylinder is provided with rows of locking bolt bores with its bores so arranged that there is a locking pin bore in alignment with each tumbler pin bore in a given rotative position of the inner cylinder with respect to the outer cylinder; an inwardly spring biased tumbler pin is provided in each tumbler pin bore and a cooperating lock bolt is arranged in each locking bolt bore; the spring biased tumbler pin causes the locking bolt to preclude rotation of the inner cylinder with respect to the outer cylinder until a key provided with specifically located recesses on its surface is inserted in a key slot provided in the inner
  • the present invention relates to an improved cylinder lock and its associated key, such lock being of the type wherein an inner cylinder or plug provided with a keyguide is rotatably mounted in an outer cylinder.
  • the inventive cylinder lock further incorporates locking bolts and spring-loaded tumbler pins or bolts operably associated with the former which are displaceably mounted in bores extending radially of the lengthwise axis of the inner cylinder. These bores are arranged in a row in side by side or juxtapositioned relationship in at least one plane which can contain or else extends substantially parallel to the aforesaid axis of the inner cylinder. Such plane, when the key is inserted, extends substantially perpendicular to the work or effective surface of the key provided with recesses for the engagement of the aforementioned locking bolts.
  • a further disadvantage of known cylinder locks resides in the fact that, with a given length of the cylinder only a limited number of combination possibilities are available when setting up or fitting the cylinder lock and the different associated keys for various users, that is, for the so-called permutation of such cylinder lock. In this regard, it must also be recognized that to obtain these different combinations, a number of bolts must be eliminated which considerably reduces lock security.
  • Another important object of this invention is to provide an improved cylinder lock which atfords a high degree of security, is relatively inexpensive to manufacture, highly reliable in operation, and allows for a large number of combination possibilities.
  • Still a further considerable object of this invention relates to an improved construction of cylinder lock which is extremely functional while providing great security, and wherein the key associated therewith is not only attractive in appearance but of sufficient strength that the tendency for it to break is, as a practical matter, almost completely eliminated.
  • the inventive cylinder lock is manifested by the features that, the inner cylinder or plug is provided at at least one plane extending at an inclination to the effective key surface, when the key is inserted, with additional bores provided with locking bolts and arranged next to one another in a row, said bores being operably associated with bores arranged at the outer cylinder which are provided with tumbler pins. Moreover, at the effective surface of the key additional recesses are provided which are operatively associated with the locking bolts displaceably mounted at the additional bores of the inner cylinder.
  • FIGURE 1 is a fragmentary, side view of a preferred embodiment of a cylinder lock designed according to the teachings of the invention and as viewed from below;
  • FIGURE 2 is a cross-sectional view of the cylinder lock depicted in FIGURE 1, taken along the line IIII thereof;
  • FIGURE 3 is an enlarged side view of the key belonging to the cylinder lock of FIGURES 1 and 2.
  • FIGURE 1 depicting the cylinder lock as seen from below, there will be clearly recognized the mouths of four additional bores which are provided in addition to these main bores. These additional bores 1 are downwardly inclined with respect to the horizontal and are arranged at the periphery of the outer cylinder 2.
  • the main bores 3 of the outer cylinder 2 are situated in a respective row side by side or adjacent one another in two horizontal axial planes H and H of the inner cylinder 4.
  • the additional bores 1 have their respective longitudinal axis situated substantially perpendicular to the lengthwise axis A of the inner cylinder 4, and these last-mentioned plans S and S are offset or displaced with respect to this axis A and in relation to the corresponding plans and S of the main bores 3 of the outer cylinder 2.
  • the inner cylinder or plug 4 provided with a downwardly directed key-guide 5 is eccentrically mounted for rotation in the outer cylinder 2 which, in turn, is enclosed by a coaxial circular cylindrical sleeve 6 fixedly connected therewith.
  • the main bores 3 of the outer cylinder 2 have associated therewith aligned and coaxial main bores 7 of the inner cylinder 4. These main bores 7 are thus arranged juxtapositioned in two rows in both the previously mentioned horizontal axial planes H and H of the inner cylinder 4.
  • Such planes H and H with inserted key 8 extend substantially perpendicular to the effective side surfaces or faces 11 of this fiat key 8 (FIGURES 2 and 3) provided with recesses 9 engaged by locking bolts or pins 10 displaceably mounted at the main bores 7.
  • tumbler bolts or pins 13 which are subjected to the action of springs 12 and are displaceably mounted in the aligned main bores 3 of the outer cylinder 2.
  • these tumbler pins 13 v are displaced from their locking position Where they extend into the bores 7 of the rotatable inner cylinder 4, further towards the outside such that they release the inner cylinder or plug 4 so that it can carry out its rotary movement.
  • the inner cylinder 4 has additional bores 14 arranged in a respective row next to one another in two different planes E and E which in the depicted embodiment each extend at an angle of inclination of about 45 to a respective one of both effective side surfaces 11 of the inserted key 8. Both of these planes E and E are downwardly inclined with respect to the common horizontal plane H H of the main bores 7. Additional recesses 15 are provided at the side surfaces 11 of the key 8 and with which locking pins or bolts 16 can engage. These locking bolts 16 are displ'aceably mounted in the additional bores 14 of the inner cylinder 4.
  • both of the planes E and B are downwardly inclined at a respective angle of about with respect to the horizontal central plane of the inner cylinder 4 in which both planes H and H of the main bores 7 lie as axial planes of this cylinder, the line of intersection G is situated beneath the axis of rotation A of the inner cylinder 4, yet extends parallel to it, and specifically, within the vertical central plane VV of the blocked inner cylinder 4.
  • the additional bores 1 and 14 and the associated pins 17 and 16 respectively, are here smaller in diameter than the main bores 3 and 7 and their associated pins or bolts 13 and 10 respectively.
  • Figure 3 depicts the key 8 associated with the previously describcd cylinder lock of FIGURES 1 and 2. It will be recognized that at the work or effective side surfaces 11 of this key 8 there are provided, not only the recesses 9 for the locking pins 10 of the main bores 7, but also the recesses 15 for the locking pins 16 of the additional bores 14 of the inner cylinder 4. On the other hand, both of the ridges of such key 8, and designated by reference character 8a, are smooth throughout their entire length.
  • additional recesses 15 in conformity with the planes E and E of both rows of additional bores 14 which extend at an inclination to both side surfaces 11 of the inserted key 8, also must extend at an inclination to such key side surfaces it is not possible to form or apply additional recesses in order to produce a passkey, by means of a normal borer or with the aid of a file at the side surfaces 11 of such key.
  • a further advantage resides in the fact that, for instance, through the arrangement of two additional bores in each of the bore planes E and E inclined to the horizontal (compare FIGURES 1 and 2), four additional security measures are available, that is, one in the plane E one in the plane E and two provided by the keyhole.
  • four additional security measures are available, that is, one in the plane E one in the plane E and two provided by the keyhole.
  • the rows of additional bores When the key is inserted, the rows of additional bores must not extend at an angle of inclination of 45 to the effective or work surfaces of the key, rather other angles of inclination are also readily possible. It is also by no means absolutely necessary when two or more rows of bores are provided to have all of the planes associated with such rows inclined at the same angle to the effective key surfaces, rather such planes could be arranged at different angles of inclination at one and the same cylinder.
  • the diameter of the additional bores with the usual cylinder length, are generally dimensioned smaller than the diameter of the main bores for reasons of space.
  • the planes of the additional rows of bores must not extend eccentrically to the axis of rotation of the inner cylinder, rather they can also be axial planes of such cylinder.
  • a cylinder lock with associated key in which cylinder lock an inner cylinder provided with key-guide means is rotatably mounted in an outer cylinder and in which cylinder lock tumbler pin means are provided; each of said tumbler pin means comprising a tumbler pin under-portion engageable with an effective key surface and an associated spring-loaded tumbler pin upperportion; said tumbler pin under-portions and said springloaded tumbler pin upper-portions associated therewith are displaceably mounted in bores, including a main bore means in inner and outer cylinders, for sliding movement within said main bore means relatively to the lengthwise axis of said inner cylinder; said main bore means extending substantially radially with respect to the lengthwise axis of the inner cylinder and being arranged in a row extending in the direction of the lengthwise axis of said inner cylinder, with the bores in said row spaced with respect to each other in a first plane; said first plane being parallel to a second plane extending parallel to said lengthwise axis of said inner cylinder; said first plane when the key is inserted
  • each of said planes containing said respective rows of additional bores extends at an angle of about 45 to both of said effective surfaces of the key when the latter is inserted into said cylinder lock.
  • each of said planes containing said respective rows of additional bores extends at different angles of inclination to said effective surfaces of the key when the latter is inserted into said cylinder lock.
  • second additional bores and said first-mentioned additional bores constitute a piurality of rows of bores extending in a direction lengthwise of the axis of said inner cylinder and lying in (planes at right angles to the longitudinal axis of the inner cylinder, said row of said second additional bores lying in planes offset with respect to said row of said first-mentioned additional bores and with respect to the planes of said main bore means.
  • a cylinder lock and associated key comprising an outer cylinder and an inner cylinder rotatable within said outer cylinder; key guide-means, including parallel guide surfaces, located within said inner cylinder; at least a row of main locking pin bores and at least a row of tumbler pin bores in said inner and outer cylinders, respectively, and lying in a first common plane with each locking pine bore being in axial alignment with an associated tumbler pin bore; said first common plane extending perpendicularly to a second plane that is parallel to said parallel guide surfaces of the key-guide means; at least a row of similarly aligned additional locking pin and tumbler pin bores lying in a third common plane which is inclined relative to said second plane and wherein said locking pin bores terminate in a surface of said key-guide means; key means provided with opposed longitudinally extending parallel locking pin engaging surfaces for insertion in said key-guide means; a locking pin disposed in each of said locking pin bores; an inwardly directed spring biased tumbler pin disposed in each of
