Definitions

  • the invention relates to a wafer-type tumbler cylinder and key, the cylinder shaft of which facilitates the placement of the wafers and springs and, furthermore, enables the fabrication of a narrow width, corrugated contour keyway; at the same time, the key has a serrated blade, the fabricated cut surfaces of which result in a corrugated contour key.
  • Conventional wafer-type tumblers are typically comprised of a sleeve 1a, a cylinder 2a, and a plurality of wafers 3a and their springs 4a.
  • the sleeve 1 a consists of a sleeve body 10 having a bore 11 extending through it lengthwise, a minimum of one lengthwise slot 12 disposed along the inside of the bore 11, and a bearing edge 13 at the leading end of the bore 11. As shown in FIG.
  • the cylinder 2a has a keyway 21 through the center and, furthermore, a flange 22 and a drive section 23 at the front and rear ends, with a shaft 20 movably installed in the bore 11 of the sleeve la; the shaft 20 has disposed one or more diametrically oriented, rectangular through-holes 24 and, furthermore, at the two sides of each rectangular through-hole 24 is a C-shaped recess 25 and a horizontally oriented U-shaped recess 26 (as shown in FIG. 16 and 17 ), for the installation of one or more wafer 3a and spring 4a sets.
  • the cylinder 2a after the installation of the wafers 3a and their springs 4a, is first fitted into the bore 11 of the sleeve 1a and, furthermore, such that the one end of each wafer 3a is subjected to the elastic force of its spring 4a, and then postured against and inserted into the slot 12 inside the bore 11, thereby obstructing the clockwise and counter-clockwise rotation of the cylinder 2a situated in the bore 11; at the same time, the flange 22 at the front end of the cylinder 2a is seated on the bearing edge 13 at the leading end of the bore 11 in order to inset securely the bore 11; additionally, the drive section 23 at the rear end of the cylinder 2a is mounted with a lock tool or electric driver so as to check whether the tumbler is locked or electrified.
  • each wafer 3a of the conventional wafer-type tumbler in addition to a window 31 in the middle thereof, has an opposing spring tab 32 and a locating tab 34; when the wafer 3a is inserted into each rectangular through-hole 24 on the shaft 20 of the cylinder 2a, it is first necessary to install a spring 4a into the C-shaped recess 25 at one side of the rectangular through-hole 24, following which the wafer 3a is then inserted into the rectangular through-hole 24; but during the installation, since the wafer body 30 of the wafer 3a has the spring tab 32, its insertion occurs without any resistance along the C-shaped recess 25; however, the locating tab 34, disposed in the other side of the wafer body 30, must similarly undergo insertion through the C-shaped recess 25 along the rectangular through-hole 24, and, as a result, friction occurs along the interior wall of the rectangular through-hole 24 at the lateral extent of the C-shaped recess 25, and only after this does the wafer body 30 reach into the horizontally oriented U-shaped rece
  • the locating tab 34 on the wafer body 30 is nested onto the bottom of the horizontally oriented U-shaped recesses 26; however, the height of the locating tab 34 is quite limited and, furthermore, the locating tab 34 is subjected to the outwardly exerted elastic force of the spring 4a, the wafer 3a is often ejected out of the rectangular through-hole 24.
  • Such situation results in a troublesome and inconvenient assembly operation as the cylinder 2a is inserted into the bore 11 of the sleeve 1a, which likewise adversely affects the production process.
  • the rectangular keyway 21 must be disposed through the center of the shaft 20 to facilitate insertion of the serrated blade 51 on the key 5a (as shown in FIG. 19 ), which causes each wafer 3a extending into the end of the slot 12 in the bore 11 to fully react within the outer diameter of the shaft 20, thereby achieving the objective of locking or unlocking.
  • the cylinder 2a of the conventional wafer-type tumbler is typically made of aluminum-zinc alloy material in an integrated molding process, and the keyway 21 disposed through the center of the shaft 20 also penetrates the internal section of the shaft 20; as a result, it is not possible to mold a corrugated keyway having a narrow width. It's only possible to mold a keyway with a width of 1.5mm or more, and as indicated in FIG.
  • the shape of the keyhole 211 only can be formed as reverse Z-shaped or other similar contour, which has a triangular projecting element 212 at the two lateral inner sides of the keyhole 211 respectively (one triangular projecting element is concealed by the flange 22, so it's not viewable); the keyway 21 along the internal section of the shaft 20 not only is formed as relatively wide rectangular shape, but also has disposed at most one lengthwise triangular projecting element 212 at one side of the keyway 21, as indicated in FIG. 15 and 18 .
  • the prior art is easily broken by thieves and pried or unlocked by burglars.
  • the serrated blade 51 of the key 5a must be fabricated of a thicker metal plate. Even though the whole key 5a may be formed by punching the metal plate, the serrated blade 51 (as indicated in FIG.
  • the objective of the invention herein is to provide a cylinder that better facilitates the installation of the wafers and their springs and, furthermore, facilitates the production of a shaft having a corrugated contour keyway with a narrower width to prevent from theft or using metal sheets and other equivalent tools to pry or unlock the wafer-type tumbler cylinder.
  • Another objective of the invention herein is to provide a serrated blade of the key, wherein a very thin metal plate is punched to directly produce its sectional shape into a corrugated contour to prohibit theft by the replication of the wafer-type tumbler cylinder and key.
  • two half keyways constitute a complete keyway, after integrating a first and second semicircular columnar body into a unity, such that the corrugated contour of the keyway has a narrower whidth of 0.5 mm approximately and by the fact that a serrated blade disposed on the key is produced by directly punching an approximately 0.5 mm or thinner metal plate.
  • the shaft of the cylinder consists of a first and a second semicircular columnar body that are insertionally conjoined into an integration, and furthermore, respectively disposed at the front and rear ends of the first semicircular columnar body are a flange and a drive section; although, on the inner lateral surfaces of the first and second semicircular columnar bodies, one or more diametrically oriented U-shaped slots are disposed; only disposed in each U-shaped slot on the first semicircular columnar body are rectangular notches having fitted with the dimensions of the wafers as well as the springs, thereby facilitating the initial placement and positioning of each wafer and its respective spring into each said U-shaped slot and rectangular notch on said first semicircular columnar body, following which the second semicircular columnar body is then fitted thereon for assembling into an integration; thereafter, the cylinder, with the wafers and their springs installed already, is inserted into the shaft hole of said sleeve to complete the assembly of the wafer-type tumbler of the present invention
  • the second semicircular columnar body via the insertion of said posts through said holes, is installed with the first semicircular columnar body into an integration; thus, the keyway along the common center of the first and the second columnar bodies is formed as corrugated contour with a narrower width (approximately 0.5mm), which effectively makes it impossible for thieves to pry or unlock by inserting metal sheets or other equivalent tools.
  • the serrated blade of the key is produced by directly punching a metal plate (approximately 0.5mm in width), and also has a thicker plastic grip coated at the opposite end thereof to thereby facilitate the user holding the key for locking and unlocking the wafer-type tumbler.
  • the production is extremely simple and convenient, but it's difficult to replicate by thieves.
  • the shaft of the cylinder consists of a first and a second semicircular columnar bodies with identical shape and dimension, which are combined into an integration; furthermore, a semicircular tenon respectively disposed at the front and rear ends of each said semicircular columnar body enables, following the installation with a plurality of wafers and their springs, the respective fitting of a sleeve ring and a drive section onto the front and rear ends to thereby assemble one shaft.
  • the shaft of the cylinder, between every two diametrically oriented U-shaped slots at the inner lateral side of the two semicircular columnar bodies, includes a relatively wider rectangular notch; at the same time, each of the wafers is a wafer body having a horizontal L-shaped tab; when each wafer is positioned between every two diametrically oriented U-shaped slots, only one spring is disposed in the relatively wider rectangular notch to serve as a common-use spring for every two wafers. Therefore, the component cost of the spring is reduced by half and it's able to prevent from prying effectively.
  • the wafer-type tumbler of the invention herein in common with the above-mentioned conventional wafer-type tumbler, is comprised of a sleeve 1, a cylinder 2, a plurality of wafers 3 and their springs 4; the structure of the sleeve 1 and the method for installing with the cylinder 2 are the same as those of said conventional wafer-type tumbler. There is no need to go into details.
  • a shaft 20 of the cylinder 2 as shown in FIG.
  • FIG. 2 consists of a first and a second semicircular columnar body 20a and 20b that are integrated with each other; furthermore, respectively disposed at the front and rear ends of the first semicircular columnar body 20a are a flange 22 and a drive section 23; at the inner lateral surface between said flange 22 and drive section 23 is an inverted U-shaped indentation 201, the length of which matches with the second semicircular columnar body 20b so as to complete the assembly of the shaft 20 on the cylinder 2 (as indicated in FIG.
  • one or more diametrically oriented U-shaped slots 24a and 24b are disposed for the installation of said wafers 3; however, only in each of the U-shaped slots 24a on said first semicircular columnar body 20a is disposed a rectangular notch 27 matching the dimension of the spring 4, thereby facilitating the placement of each wafer 3 and its spring 4 into each said U-shaped slot 24a and said rectangular notch 27 on said first semicircular columnar body 20a, following which the second semicircular columnar body 20b is then fitted thereon for an integral unity; after that, the shaft 20 of said cylinder 2 is inserted into a shaft hole 11 in said sleeve 1 to assemble the wafer-type tumbler of the present invention, as illustrated in FIG. 5 as well as FIG 5-1 .
  • two half-keyways 21a and 21b are formed as corrugated contour in the center of the inner lateral surfaces thereof; furthermore, one or more posts 28 (as shown in FIG. 2 ) and holes 29 (which are concealed by the second semicircular columnar body 20b, so please refer to FIG. 4 ) are disposed at the front and rear ends of each said inner lateral surface.
  • the second semicircular columnar body 20b via the insertion of said posts 28 through said holes 29, is correspondingly fixed with the first semicircular columnar body 20a into a unity so as to complete the assemblage of the cylinder 2, as indicated in FIG.
  • a keyway 21 (as shown in FIG. 4 ) is formed as corrugated contour, with a narrower width of 0.5mm, thereby preventing theft by means of a metal sheet or other equivalent tool inserted for burglarizing.
  • a serrated blade 51 of a key 5 (as depicted in FIG. 6 and 7 ) is produced by directly punching an approximately 0.5mm or thinner metal plate, and a plastic grip 52 is coated onto the opposite end thereof, thereby facilitating the user holding the key for locking and unlocking the wafer-type tumbler; it is not necessary to mill and plane any lengthwise grooves nor other milling and planing processes.
  • the drive section 23 is shaped as square or rectangular rod body 230, said drive section 23 may be shaped as threaded, circular, oblate, tubular or other shaped rod body (not shown in the drawings) to make the design of said drive section 23 match with a lock tool or electric driver, thereby enabling said drive section 23 to fasten with said lock tool or electric driver by means of screws or rivets.
  • the wafers 3 of the wafer-type tumbler of the invention herein do not require mounting in rectangular through-holes 24 (as depicted in FIG. 14 of the prior art), said wafers 3 can be fixed on said shaft 20 securely, as shown in FIG 1 , by a window 31 in the center of each wafer body 30 of the wafer 3 along with a spring tab 32 at one side thereof, and there is no need to dispose any locating tab 34 thereon.
  • a shaft 20' on the cylinder 2' consists of a first and a second semicircular columnar body 20'a and 20'b (both of identical shape and dimension) that are conjoined into an integral unity; furthermore, respectively disposed at the front and rear ends of each semicircular columnar body 20'a and 20'b is a semicircular tenon 202 and 203 which is respectively fitted onto a sleeve ring 22a and a drive section 23 to constitute a cylinder 2', as indicated in FIG. 8 .
  • the said semicircular tenons 202 at the front ends of said semicircular columnar body 20'a and 20'b are correspondingly coupled to form a circular tenon, and the said semicircular tenons 203 at the rear ends thereof are correspondingly coupled to form a circular tenon.
  • the sleeve ring 22a has an inner hole 221 in a ring body 220a, which is a D-shaped hole with a minimum of one secant planar edge 222 along one lateral wall, and furthermore, an opening 223 through one side of the ring body 220a, wherein the center of said opening 223 is aligned and parallel with said secant planar edge 222; a facet 204 is disposed correspondingly along the outer extent of the semicircular tenon 202 of the semicircular columnar body 20'b.
