  • Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.
  • A lock is a mechanical or an electronic device for restricting access to an enclosed property. More specifically, the lock is adapted to protect against forced and surreptitious entry to the enclosed property or the particular area. The lock may be used on a door, furniture, a vehicle, a container such as a storage box or a bike.
  • A clutch mechanism inside a lock system often functions to converting a torque power, such as a rotation, into a linear movement, which leads to coupling or uncoupling of various components in the lock therefore locking or unlocking the lock system.
  • SUMMARY
  • The following summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.
  • In one aspect, the disclosure provides clutches for locks. In one embodiment, the clutch includes a first clutch shaft, a second clutch shaft, and a clutch driver shaft. The first clutch shaft and the second clutch shaft may be configured to rotate concentrically. The first clutch shaft and the second clutch shaft are configured to be operably coupled by a follower. The clutch driver shaft may be coupled to the follower in such a way that the rotation of the clutch driver shaft is configured to produce a linear reciprocating motion on the follower.
  • In one embodiment, the first clutch shaft may have a first opening and is configured to receive at least a portion of the second clutch shaft. The second clutch shaft may have a slot. The first opening and the slot are configured to align when rotating the first clutch shaft, the second clutch shaft, or both.

  • DETAILED DESCRIPTION
  • In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.
  • This disclosure is generally drawn, among others, to clutching mechanisms, locks containing the clutching mechanism, and methods, apparatus, systems, and/or devices related to the locks and the clutching mechanism clutches. For example, the present disclosure relates generally to lock systems which may be employed with entry control devices to control access through a door or to furniture. The clutch mechanisms and lock systems containing the clutching mechanisms provided in this disclosure may have the advantage of, without limitation, simple, durable, easy to use, and low production cost.
  • In one aspect, clutches for locks are provided. In one embodiment, as shown in FIGS. 1 and 2, the clutch includes a first clutch shaft (20), a second clutch shaft (1), and a clutch driver shaft (2). The first clutch shaft (20) has a first opening (22) and is configured to receive at least a portion of the second clutch shaft (1). The first clutch shaft (20) and the second clutch shaft (1) are configured to rotate concentrically. The second clutch shaft (1) has a slot (25). When rotating the first clutch shaft (20), the second clutch shaft (1), or both, the first opening (22) and the slot (25) may be aligned.
  • In one embodiment, the clutch driver shaft (2) may have a first end and a second end. The clutch driver shaft (2) is coupled to a follower (23) at the first end and is rotationally coupled to a lock cylinder (7) at the second end. The follower (23) is configured to be slidably received in the first opening (22) and the slot (25). The rotation of a lock cylinder (7) causes the rotation of the clutch driver shaft (2), which produces a linear reciprocating motion on the follower (23) sliding the follower (23) partially into or retracting the follower (23) out of the first opening (22) through the slot (25) when they are aligned.
  • When the follower (23) is retracted out of the first opening (22), the first clutch shaft (20) and the second clutch shaft (1) are operably decoupled and therefore configured to rotate independently. When the follower (23) is silded partially into the first opening (22), the first clutch shaft (20) with the second clutch shaft (1) are operably coupled and therefore configured to rotate together.
  • In one embodiment, the first end of the clutch driver shaft (2) may have a first structure (10) eccentrically located. In one embodiment, the follower (23) may have a second structure (24). The first structure (10) and the second structure are configured to couple with each other. For example, as shown in FIG. 3, the clutch driver shaft (2) may have a first protruding structure (10) at the first end. The protruding structure (10) may or may not be cylindrically shaped. The first protruding structure (10) may be eccentrically located. The follower (23) may have an indenting structure (24). The indenting structure (24) may be configured to mate with the first protruding structure (10) coupling the clutch driver shaft (2) with the follower (23). Because the first protruding structure (10) is eccentrically located, the rotation of the clutch driver shaft (2) is configured to be converted to a linear reciprocating motion on the follower (23).
  • At least a portion of the follower (23) may be received in the slot (25) and may continue into the first opening (22). Through the coupling between the clutch driver shaft (2) and the follower (23), the rotation of the clutch driver shaft (2) is configured to produce a linear motion on the follower (23) sliding the follower (23) at least partially into or retracting the follower (23) out of the first opening (22) through the slot (25) when two are aligned.
  • When the follower (23) is retracted out of the first opening (22), the first clutch shaft (20) is operably uncoupled from the second clutch shaft (1), as shown in FIG. 2. The first clutch shaft (20) and the second clutch shaft (1) are configured to rotate independently. When the follower (23) is slided at least partially into the first opening (22), the first clutch shaft (20) is operably coupled to the second clutch shaft (1), as shown in FIG. 1, causing the first clutch shaft (20) and the second clutch shaft (1) to be configured to rotate together.
  • In one embodiment, at the second end, the clutch driver shaft (2) may be coupled to a lock cylinder (7) so that the rotation of the lock cylinder (7) causes the rotation of the clutch driver shaft (2). For example, as shown in FIGS. 1 and 2, the clutch driver shaft (2) may have a second protruding structure (8) at the second hand; and the lock cylinder (7) may have an indenting structure. The second protruding structure (8) may mate with the indenting structure coupling the lock cylinder (7) to the clutch driver shaft (2). Therefore, when a user uses a key to rotate the lock cylinder (7), the clutch driver shaft (2) rotates, through the follower (23), operably coupling or uncoupling the first clutch shaft (20) and the second clutch shaft (1).
  • In another aspect, the disclosure provides lock systems having the above described clutches and clutch mechanisms. The lock systems may be a door lock, a furniture lock, a vehicle lock, or a bike lock.
  • In a further aspect, the disclosure provides doors, furniture, bikes, buildings, apparatus, devices, and systems having locks with the above described clutches and clutch mechanisms.
