Definitions

  • the present invention relates to a keylock comprising a rotating cylinder within a frame which contains diametrically disposed locking blades and return springs adapted to cause said blades to engage at one end in a locking groove of the frame when the key is withdrawn.
  • This lock is characterized by the fact that the cylinder comprises a case having end parts of generally circular shape connected to each other by two longitudinal parts, each having a cross-section having the shape of a circular segment and the parallel inner faces of which constitute the opposite walls of a crosswise recess in which there is contained a removable assembly supporting the locking blades and the return springs.
  • One of the features of the invention includes the use. of diametrically disposed locking blades which engage grooves in both sides of the frame. Such a lock is very difficult to open without the proper key.
  • Another feature of the invention is the wedge-like action of the locking blades within the grooves in the frame.
  • Theblades are spring urged to seat firmly in the grooves and make manipulation of the lock without the key practically impossible.
  • Still another feature of the invention is the manner of retaining the springs within the rotating cylinder, thereby simplifying assembly operations.
  • FIG. 1 is a longitudinal section through this embodiment along the line 11 of FIG. 2;
  • FIG. 2 is a section perpendicular to the section of FIG. 1, along the line 22 of FIG. 1;
  • FIGS. 3 and 4 are cross-sections taken along the lines 33 and 4-4 respectively of FIG. 1 on a slightly larger scale;
  • FIG. 5 is a cross-section along the line 55 of FIG. 1, on a larger scale
  • FIG. 6 is a detail view in perspective of the spring enclosures on a larger scale
  • FIG. 7 is a detail view of the locking blades on a larger scale.
  • the double-cylinder lock shown comprises in a frame 1 two opposing cylinder 2, 2' held axially in the frame by rings 3 and a tongue 4 mounted for rotation on the inner ends of the two cylinders (FIG. 2).
  • the two cylinders 2, 2' are identical; they each have a case of generally cylindrical shape 5 comprising end parts 5a and 5b of generally circular shape connected to each other by two longitudinal parts 50 and 5d having a cross-section of the shape of a circular segment (FIG. 5).
  • the inner faces 6a and 6b of the parts 50 and 5d which are established in parallel planes constitute the opposite walls of a recess 6 which passes through the cylinder.
  • the two cylinders 2, 2 are intended to turn in the frame 1. v
  • the tongue 4 has an opening 4a in the form of a cross.
  • the inner end parts Sb of the two cylinders 2 and 2 are cut so as to form diametric slots 7 and 7'.
  • the slot 7 there are engaged the diametrically opposed wings 8a and 8b of a first slider 8 which is thus fixed in rotation with the cylinder 2.
  • the slot 7' there are engaged the corresponding wings of a second slider 8' which is fixed in rotation with the cylinder 2.
  • the two sliders 8 and 8' which are rotatably mounted on a central pin 9, have cylindrical bearing surfaces housed in bores of corresponding diameter drilled in the end parts of the cylinders.
  • the pin 9 and the two sliders 8 and 8 are movable axially and in the position shown in FIGS. 1 and 2 the slider 8 is engaged in the opening 4a of the tongue 4 which is thus fixed in rotation with the cylinder 2.
  • the slider 8 which is pushed back into the slot of the cylinder 2 is, on its part, completely freed from the opening of the tongue 4.
  • the end parts of the case 5 are pierced by an axial opening 11 in which there can slide the tail 12a ofa flat key 12 shown introduced into the cylinder 2' of the lock in the lower portion of FIG. 2.
  • the shank of the key has lateral grooves 12b and the opening 11 has complementary ribs which permit the passage of the key only in one direction.
  • the length of the key is determined in such a manner that its front end 12c cooperates with the pin 9 to bring the slider of the cylinder in which the key is engaged into engagement with the tongue 4, while releasing the opposite slider from the tongue.
  • the latter can be mounted on the cylinders in four different angular positions apart from each other.
  • This possibility of mounting the tongue in positions 90 apart without turning it makes it possible to effect an adjustment of the position of the tongue by only partially withdrawing the cylinder alone whose slider is in engagement with the tongue in order to free it from said slider.
  • the other cylinder remains in position and its inner end continues to serve as pivot for the tongue which therefore cannot be freed from the frame 1.
  • the bore holes of the frame 1 containing the cylinders each have two axial locking grooves 13, 15 (FIGS. 2 and 5), which are diametrically opposite, adapted to engage the ends of the locking blades described below, and intended to prevent the cylinders from turning as long as a key of suitable shape is not introduced into the cylinder.
  • each cylinder there are housed eleven small parallel guide plates 15 which are held assembled in a package by two axial rods 16 threaded in corresponding holes of said plates (FIGS. 1 and 3).
  • the stationary plates 15 and the rods 16 thus constitute a removable unit inserted in the continuous recess 6 of the case 5 of the cylinder.
  • Each plate 15 has a straight edge 15a resting against the adjacent face 6b of the recess 6, two circular edges 15b and 15c being inscribed in the bore of the frame 1, and a linear edge 15d parallel to the edge 15a which is engaged in a narrow corresponding groove 60 recessed in the face 6a of the recess 6 (FIGS. 1 and 5).
  • the edge 15d is on an edge portion 15e of the plate which is thinner due to lateral recesses 15: recessed in the latter (FIG. 6).
  • the recesses 15 house the return springs 25 for the locking blades.
  • Each blade 19 contains a notch 22 cut therein.
  • This notch comprises a bottom part 23 through which the shank 12a of the key passes and an entrance part 24 (FIG. 5).
  • One edge 23a of the notch is adapted to cooperate with the lower edges of the key, while a spring compressed between an edge 24a of the notch and a bearing plate 26, urges the blade 19 downward (FIG. 5).
  • the blade 19 is moved by the spring 25 into an extreme lower position determined by the stop of the lower end part 190 of the blade in the corresponding locking groove 14 (FIG. 5).
  • the blade is caused to rise upon the passage of a high portion of the key such as that indicated at 122 (FIG. 5) or 12a (FIG. 2) and the opposite end part 19d of the blade 19 which is caused to pass beyond the outer surface of the cylinder, then passes momentarily into the opposite groove 13. Since the locking grooves 13 and 14 are slightly staggered laterally towards the left with respect to the axis BB of the cylinder (FIG. 3), the key can therefore be withdrawn only in the single angular position of the cylinder which is shown in the figure.
  • the bearing plate 26 is engaged, as can be noted from FIG. 6, in longitudinal grooves 27a recessed in the linear edges 15d of the plates 15 and which extend in directions perpendicular to the slots 20.
  • the grooves 27a are arranged along two lines which are shifted laterally from the axial plane of the cylinder.
  • the locking blades 19 can be mounted in both directions in the slots 20 to cooperate with one or the other of the edges of the key, the corresponding bearing plate 26 being displaced accordingly.
  • a common bearing plate 2611 can be provided.
  • the plates 15 connected by the rods 16 can be replaced by a single element in which there are developed guide slots for the locking blades 19 and the springs 25.
  • This element which is produced, for instance, by molding, could also have foundry cast bridges resulting from casting to replace the bearing plates 26. These bridges can be provided in different positions, depending on the type of cylinder. Such a method of manufacture which makes it possible to reduce the cost is particularly indicated in the case of locks intended for the automobile industry which must be very low in cost.
  • the locking groove 14 has lateral flanks 14a, 14b which are inclined with respect to each other and the end parts of the locking blades engaged in said groove have lateral edges which have the same inclination.
  • the groove 13 and the opposite end parts of the blades are shaped in the same manner.
  • the widths dx, dy, dz of the end of the blades of different lengths varies so that the outer angles X, Y, Z of the blades are not arranged in the same plane but are shifted laterally, as indicated at el and e2 in the case of the blades which are visible in FIGS. 7.
  • the assembly of the locking blades which varies from one lock to another can be mounted as a unit in the case of the cylinder by simple sliding in the recess passing through the latter. These units can be prepared in advance and delivered separately for mounting as required in the locks.
  • the angular position of the tongue can easily be modified so as to form a right-hand or left-hand lock without having to turn the tongue around and by means of a very limited displacement of only one of the cylinders.
  • the locking blades and the intermediate guide plates can easily be formed by stamping, which also decreases the cost of manufacture.
  • a lock having a rotatable cylinder. and a series of diametrically positioned locking blades housed in a frame, the improvement comprising:
  • said locking blades formed with ends having straight inclined sides for tightly engaging said locking grooves in the frame;
  • a return spring for each locking blade said springs positioned in the rotatable cylinder and engaging a plate secured to the cylinder and a portion of the locking blade for urging the blade to move one of its ends into its locking groove;
  • a lock according to claim 1 wherein the rotatable cylinder is removable and is formed by a series of guide plates connected to each other by at least one traverse rod, said guide plates each formed with a notch for producing slots for positioning said locking plates.
  • a lock according to claim 1 wherein two rotatable cylinders are mounted in axial alignment, one on each side of a supporting member for operation by a key from either side; said cylinders coupled to an operating tongue which is axially movable by the end of the key to engage a bolt for operating the lock.
