Description

Movable key combination element for triggering of shear line

The present invention generally relates to a locking device and, more specifically, relates to a key combination element movably arranged in a key blank or key that interacts with a lock assembly.

There are prior art keys in which a movable key combination element can linearly protrude from both sides of the key, for example, as shown in PCT published patent applications WO 2008/015672 and WO 2016/161530 and European patent EP 3354826. However, there is no prior art key having a pair of side-by-side movable key combination elements with a pair of shear lines that bring a pin or pins positioned in a cylinder lock cylinder to the same side of the movable key combination element and the key device. In other words, no prior art key has a pair of side-by-side movable key combinations for triggering a shear line on the same side of the key device.

The present invention seeks to provide a laterally offset movable key combination element for triggering by a shear line on the same side of the key device, as described in more detail below. (Lateral offset means offset along the width of the key device.) The movable key combination element can linearly protrude from both sides of the key device. The side-by-side movable key combination elements are configured for shear line triggering on the same side of the key device. A novel cylinder lock used with this novel key device is also described.

It should be noted that throughout the specification and the scope of the invention application, the term "key device" refers to a key blank or a key made of a key blank with a key cut formed on it.

The key device of the present invention not only opens the cylinder lock of the present invention, but is also compatible with the cylinder lock associated with the key device of U.S. Patent 8,387,425, which is described in U.S. Patent 9,14034. In contrast, the key device of US Pat. No. 8,387,425, in which the movable key combination element cannot protrude from both sides of the key device, cannot operate the cylinder lock of the present invention.

1A and 1B, which illustrate a key device 50 constructed according to a non-limiting embodiment of the present invention. The key device 50 is shown without a key cutout but may have a key cutout formed therein.

The key device 50 has a shaft portion 52 extending along a shaft axis 54 and may include a first key combination surface 56 and a second key combination surface 58 (for a reversible key device; although the present invention can be implemented for an irreversible key device).

1C shows a key device 50 having at least one movable key combination element 60 (two are shown here) held in an elongated shaft portion 52. Figures 1A and 1B show a key device 50 without a removable key combination element in order to better show the aperture for receiving the removable key combination element.

As seen in FIGS. 2A and 2B, each movable key combination element 60 may include a first portion 62 and a second portion 64 adjacent to each other. The first part 62 is narrower than the second part 64, thereby creating a shoulder 59, which can be used to prevent the element 60 from falling out of the key device 50 as explained further below. In one example, the first portion 62 may be circular and the second portion 64 may be elongated, oblong, or elliptical. The movable key combination element 60 can be manufactured in any suitable manner, such as by press-fitting the first part 62 into the second part 64.

In a preferred embodiment, as seen in Figure 1C, the key device is reversible and includes two side-by-side movable key combination elements 60, both of which can be used to move the pins of a cylinder lock from the key combination surface 56 and Either or both of 58 bring everything to change. The elements are side by side in the transverse direction; transverse means perpendicular to the longitudinal axis 54 of the shaft part 52. It should be noted that “side-by-side” not only covers exactly side-by-side but also covers a situation where one of them is slightly forward in the longitudinal direction than the other, so that the elements overlap at least partially in the longitudinal direction.

3A, which illustrates the position of the movable key combination element 60 when the key device is inserted into the key slot of the cylinder lock. On each of the key combination surfaces 56 and 58, the first portion 62 of one of the elements 60 is adjacent to the second portion 64 of the other of the elements 60. The first portion 62 and the second portion 64 of each element 60 extend from each other along the width of the key device 50 (ie, in a direction perpendicular to the transverse direction and the longitudinal axis of the shaft portion 52 (perpendicular to the drawing of FIG. 3A)) .

Also refer to Figure 3B and Figure 3C. Two side-by-side movable key combination elements 60 can protrude from the first key combination surface 56 (FIG. 3B), and each movable key combination element 60 can individually protrude from the second key combination surface 58 (FIG. 3C). Therefore, the two side-by-side movable key combination elements 60 can be moved independently of each other. Any combination of movement is possible, such as only one of the elements 60 protruding from the first key combination surface 56, or both protruding from the first key combination surface 56, or only one of the elements 60 from the second key combination surface 58 Protruding, or both protruding from the second key combination surface 58.

As seen in FIG. 3A, the first part 62 may be movably installed in a first guide aperture 66 (for example, a circular hole) formed in the shaft part 52, and the first guide aperture 66 may be formed It has a shoulder 67 (for example, a countersunk hole). The second part 64 can be movably installed in one of the second guiding holes 68 formed in the shaft part 52. A retaining structure is provided to prevent the element 60 from falling out of the key device 50. For example, the second guiding hole 68 may be formed to have a shoulder 69 (for example, a countersunk hole). The displacement of the second part 64 is restricted by the body of the second part 64 that abuts the shoulder 69. As previously mentioned with reference to FIGS. 2A and 2B, the first portion 62 is narrower than the second portion 64 and this creates a shoulder 59 that can abut the narrower second guide aperture 68 to prevent the element 60 from being removed from the key device 50 drop.

The second part 64 of one of the elements 60 does not extend over the second part 64 of the other of the elements 60. In addition, a central axis 61 of the first part 62 is not collinear with a central axis 63 of the second part 64 but is offset from the central axis 63 of the second part 64.

As another option (shown in dashed lines in FIG. 3B ), the central axis 63 of the second part 64 and the central axis 61 of the first part 62 are collinear. (This is the configuration shown in Figure 2A and Figure 2B.)

Compared with the prior art, the second guide aperture 68 formed on the first key combination surface 56 does not extend into the first guide aperture 66 on the first key combination surface 56 and does not extend to the second key combination surface. 58 on the second guide aperture 68. Instead, a wall 65 separates the apertures 66 and 68 of the movable key combination elements from each other. This provides a seizure-free guiding path for each movable key combination element to protrude from both the key combination surfaces 56 and 58.

Referring now to FIG. 4, it illustrates a cylinder lock 70 constructed in accordance with a non-limiting embodiment of the present invention.

The cylinder lock 70 includes a lock cylinder 72 having a key slot 74 for inserting a key device into one of the key slots 74. The lock post 72 is configured to move (rotate) around the all-changing line 76 in a lock body 78. In the illustrated embodiment, the lock body 78 is a European contour cylinder lock body, but the present invention is not limited to this lock body. The lock cylinder 72 can rotate a cam 73, as is known in the art.

One or more movable elements are slidably disposed in the opening formed in the lock post 72. In the illustrated embodiment, there is a first movable element 80 and a second movable element 82. The first movable element 80 includes a first part 80A and a second part 80B. In the illustrated embodiment, the first part 80A and the second part 80B are connected to each other by a connecting member 83. Alternatively, the first part 80A and the second part 80B need not be connected to each other.

Referring now to FIG. 5, it shows the key device 50 inserted into the key slot. Both the first part 80A and the second part 80B face the first key combination surface 56 and move in the openings 85 and 87 formed in the lock cylinder 72, respectively. On the first key combination surface 56, the first portion 80A is aligned with the second portion 64 of one of the movable key combination element 60, and the second portion 80B is aligned with the first portion 62 of the other of the movable key combination element 60 alignment.

The first movable element 80 includes a protrusion 88 initially received in a groove 89 formed in the lock body 78 (that is, in the locking orientation of FIG. 5 ). The groove 89 may be relatively wide as it opens toward the lock cylinder 72 and may taper to a narrower width in a direction away from the lock cylinder 72. The protrusion 88 has a complementary tapered shape to fit in the groove 89.

Now refer to Figure 4 again. The second movable element 82 can be a multi-pin or telescopic pin element, which has an inner pin 90 and an outer pin 92. The opening 94 in which the second movable element 82 is disposed is formed to have a countersunk hole 96 facing the shear line 76 and opposite to the groove 89.

The cylinder lock 70 may include one or more drive pins 98 slidably disposed in the lock body 78. The driving pin 98 applies a biasing force toward the second movable element 82, such as by a spring 100 (or a magnet or other biasing device). The driving pin 98 can be a multi-pin or telescopic pin element, which has an inner pin 102 and an outer pin 104.

As seen in FIG. 4, in the case of inserting the keyless into the key slot, the driving pin 98 pushes against the second movable element 82, which in turn pushes against the first movable element 80, thereby The protrusion 88 is pressed into the groove 89 and the rotation of the lock cylinder 72 is prevented. (Of course, the drive pin 98 also prevents the lock cylinder 72 from rotating because it crosses the shear line 76.)

As seen in FIG. 5, the key 50 is inserted into the key slot without the movement of the lock cylinder 72 in the lock body 78 without aligning the movable elements 80 and 82 with the shear line 76. When the key 50 is inserted into the key slot 74, the drive pin 98 extends into the counterbore 96 before the lock cylinder 72 moves in the lock body 78.

Referring now to FIG. 6, it illustrates the initial movement (for example, rotation) of the lock cylinder 72. The protrusion 88 of the first movable element 80 starts to move out of the groove 89, thereby causing the first part 80A to push against the second part 64 of one of the movable key combination elements 60, and the second part 80B to push against the movable The first part 62 of the other of the key combination element 60. This causes the first part 62 extending from the second part 64 of one of the movable key combination elements 60 to push against the second movable element 82, which in turn presses the drive pin 98 to the shear line 76. Therefore, after the lock cylinder 72 moves in the lock body 78, the first movable element 80 moves against the movable key combination element 60, and the movable key combination element 60 moves against the second movable element 82. The movable element 82 moves against the driving pin 98 to overcome the biasing force of the spring 100 and cause the driving pin 98 to move out of the counterbore 96 to the shear line 76 and allow the rotation of the lock cylinder 72.

It should be noted that the chamfered shape of the protrusion 88 allows it to move out of the tapered shape of the groove 89. It should be further noted that if there is no counterbore 96, the drive pin 98 will abut the wall of the opening 94 and it will not be able to rotate the lock cylinder 72.

The second part 80B pushes against the first part 62 of the other one of the movable key combination elements 60 on the first key combination surface 56. This causes the second portion 64 to protrude from the second key combination surface 58.

It should be noted that the key device of US Pat. No. 8,387,425 cannot operate the cylinder lock 70 because the movable key combination element cannot protrude from both sides of the key device. Although one of the movable key combination elements of US Pat. No. 8,387,425 can be moved by the first part 80A, the other movable key combination element will block the movement of the second part 80B and cannot rotate the lock cylinder 72.
