This application is related to motorcycles, and particularly to devices for engaging the throttle and/or a brake lever of a motorcycle to deter theft.

SUMMARY

Disclosed herein are various embodiments of locking devices for securing a motorcycle by holding or clamping a brake lever toward the throttle such that operation of the motorcycle is impaired.

Disclosed locking devices can include a first rigid arm with a female locking mechanism at one end and a second rigid arm pivotably coupled to the opposite end. The second arm can have a male engagement portion having a plurality of notches that is insertable into and lockable with the female locking mechanism. The device has an open position wherein the first and second arms are pivoted away from each other such that the engagement portion of the second arm is spaced apart from the locking mechanism and the device is positionable around a throttle and a brake lever of a motorcycle. The locking device also has a closed position wherein the first and second arms are pivoted toward each other such that the engagement portion of the second arm is inserted into the female locking mechanism, which engages with at least one of the notches to secure the locking device in the closed position.

The locking device is adapted to extend around the brake lever and the throttle of the motorcycle in the closed position and to hold the brake lever in an engaged position toward the throttle such that a brake of the motorcycle is engaged and the motorcycle is restricted from rolling. The first arm can also frictionally engage with the throttle such that rotation of the throttle is substantially restricted. Portions of the first arm and/or the second arm can be covered with a material that creates an anti-slip engagement with the throttle and/or the brake lever when the device is in the closed position around the throttle and brake lever, to prevent rotation of the throttle and prevent the device from being slid off of the throttle and brake lever.

The locking device can comprise a ratcheting mechanism that allows the engagement portion of the second arm to enter and move further into the female locking mechanism but does not allow the engagement portion of the second arm to be moved out of the female locking mechanism. The locking mechanism can be user-actuated in various ways, such by use of a removable key or a combination lock. Actuation by the user cause the second arm to be released from the first arm so that the device can be removed from the motorcycle.

In some embodiments, the ratcheting mechanism comprises a rocker that is pivotable relative to a housing of the female locking mechanism between an engaged position, wherein the rocker engages one of the notches to prevent the engagement portion of the second arm from moving out of the lock, and a disengaged position wherein the engagement portion of the second arm is free to pivot out of the lock, and wherein the rocker is biased toward the engaged position. User actuation of the lock causes the rocker arm to be held in the disengaged position in order to open the device and remove it from a motorcycle.

The arms of the device can be have flattened or rounded inner surfaces that contact the throttle and/or the brake lever.

In some embodiments, the locking device can also include a motion sensor that detects motion of the motorcycle. The locking device can also include a battery coupled to the sensor and/or a wireless transmitter coupled to the sensor that generates a wireless signal to a remote receiver, such as the bike owner's mobile phone. The remote receiver can include an application or software that generates an alarm and/or another indication that motion has been sensed. In some systems, police or other entities can be notified automatically if motion is detected. The locking device can also include an alarm that goes off if motion is detected to help deter theft.

The foregoing and other objects, features, and advantages of the disclosed technology will become more apparent from the following detailed description, which proceeds with reference to the accompanying figures.

DETAILED DESCRIPTION

Disclosed herein are various embodiments of locking devices for securing a motorcycle by holding a brake lever toward the throttle such that operation of the motorcycle is impaired and theft is deterred. Different exemplary embodiments are shown in FIGS. 1, 1A, and 1B. FIG. 1 shows a locking device 10 that includes a key-based lock 20, FIG. 1A shows a locking device 30 that includes an alternative key-based lock 32, and FIG. 1B shows a locking device 50 that includes a combination lock, or dial-based lock, 52. The locking devices 10, 30, 50 are configured to deter the theft of a motorcycle, among other uses.

As shown in FIG. 9, any of the disclosed locking devices (embodiment 10 is shown as an example) can be placed around the hand throttle 100 and the front brake lever 110 of a motorcycle. When the locking device is placed around the hand throttle 100 and the front brake lever 110 of the motorcycle, the front brake lever is pulled in as if applying the front break to stop the motorcycle. At this point, the locking device is cinched tight to retain the brake lever 110 in the locked position. When the locking device is in the locked position, the motorcycle cannot be rolled away because the front brake is engaged and the throttle becomes useless for operating the motorcycle.

Some embodiments of the locking device comprise a combination lock (e.g., FIG. 1B), some embodiments comprise a keyed lock (e.g., FIGS. 1 and 1A), and some embodiments comprise a special shaped male key (e.g., FIGS. 7A and 8A). Each can serve the same purpose, which is to secure the locking device in place as it secures pressure on the brake lever 110 and throttle 100. The lock of the locking device can be integrated into the female portion of the locking device.

As shown in FIG. 1, the device 10 comprises a female arm 12, a male arm 14 pivotably coupled to the female arm, a serrated or notched engagement portion 16 on the male arm, and the lock 20 mounted on the female arm. A key 22 for the lock 20 is also shown. In an open position, the male arm 14 pivots away from the female arm 12 to provide enough space therebetween for the locking device to be placed over a throttle and brake lever. The female and male arms 12, 14 are then pivoted toward each other such that the engagement portion 16 moves into a cavity in the female arm and engages with the lock 20 to prevent the two arms from pivoting back apart from each other. The pivot hinge between the two arms can be pinned together with a high strength rivet, pivot pin, or other fastener.

As shown in FIGS. 2, 7A, and 8A, the lock 20 can include a ratcheting mechanism, such as including rocker 26, that engages with the notches in the engagement portion 16 to allow further relative motion between the two arms in the closing direction but prevent relative motion in the opening direction. FIGS. 3A and 4A show cross-sectional views of the lock 20 engaged with the engagement portion 16 of the male arm 14. The user can operate the lock 20 by twisting the key 22 to drive an actuator 28 that pushes a lever arm 29 of the rocker 26 and pivots the rocker to a disengaged position (see dashed lines in FIG. 2, and FIG. 8A), which allows the male arm 14 to pivot away from the female arm 12 and open the device 10. The rocker 26 can be spring biased toward the engaged position (see solid lines in FIG. 2, and FIG. 7A) such that the rocker engages the notches in the engagement portion 16 of the male arm 14 when the key 22 is turned to the locked position causing the actuator 28 to move back away from the rocker and allow the rocker to freely toggle. In the locked position, the key 22 can be removed for security.

As shown in FIG. 1A, the device 30 includes the female arm 12, the male arm 14 pivotably coupled to the female arm, the serrated or notched engagement portion 16 on the male arm, and an alternative key-based lock 32 mounted on the female arm 12. A key 34 for the lock 30 is also shown. As shown in FIGS. 2A and 2B, the lock 32 can include a ratcheting mechanism, such as including rocker 36, that engages with the notches in the engagement portion 16 to allow further relative motion between the two arms in the closing direction but prevent relative motion in the opening direction. The user can operate the lock 32 by twisting the key 34 to drive an actuator that pushes the rocker 36 to a disengaged position (see dashed lines in FIG. 2A), which allows the male arm 14 to pivot away from the female arm 12 and open the device 10. The rocker 36 can be spring biased toward the engaged position (see solid lines in FIG. 2A) such that the rocker engages the notches in the engagement portion 16 of the male arm 14 when the key 32 is turned to the locked position, allowing the rocker 36 to freely toggle. In the locked position, the key 32 can be removed for security.

As shown in FIG. 1B, the device 50 includes the female arm 12, the male arm 14 pivotably coupled to the female arm, the serrated or notched engagement portion 16 on the male arm, and a combination lock 52 mounted on the female arm 12. As shown in FIGS. 2C and 2D, the lock 52 can include a ratcheting mechanism, such as including rocker 58, that engages with the notches in the engagement portion 16 to allow further relative motion between the two arms in the closing direction but prevent relative motion in the opening direction. FIGS. 3B and 4B show cross-sectional views of the lock 52 with the engagement portion 16 engaged, and show cross-sectional views of a number wheel 54 and the actuator 56. FIG. 5B is a cross-sectional view of the female arm 12 with the engagement portion 16 of the male arm 14 inserted into female arm. FIGS. 6B and 7B show cross-sectional views of the female and male arms 12, 14. FIGS. 3C, 4C, 5C, 6C, and 7C shows the same cross-sectional views as FIGS. 3B, 4B, 5B, 6B and 7B, but for a version of the device 50 wherein the arms 12, 14 have flattened cross-sectional profiles.

From the locked position, the user can rotate the number wheels 54 to a preset combination to unlock the actuator 56, which can then slide toward the rocker 58 to push a lever arm 59 of the rocker to a disengaged position (see dotted lines in FIG. 2C), which allows the male arm 14 to pivot away from the female arm 12 and open the device 50. The rocker 58 can be spring biased toward the engaged position (see solid lines in FIG. 2C) such that the rocker engages the notches in the engagement portion 16 of the male arm 14 when the actuator is moved away from the rocker in the locked position, allowing the rocker 58 to freely toggle. In the locked position, the number wheels 54 can be rotated to a random setting to keep the lock secured.

The locking devices disclosed herein can have a non-circular overall shape, such as a generally oval shape, when viewed from the side (e.g., the view of FIG. 1), which can facilitate clamping the throttle and front break lever together in one motion when the locking device is closed.

The locking devices disclosed herein can be constructed partially or completely of any of various metals, such as aluminum, titanium, and/or steel, carbon fiber reinforced composite materials, polymeric materials, and/or other sufficiently strong and durable materials.

At least portions of the female and male arms 12, 14 of the disclose devices can have a generally cylindrical or circular cross-sectional shapes (as shown in FIGS. 5B, 6B, and 7B), or a generally flattened cross-sectional shape (as shown in FIGS. 5A, 6A, 5C, 6C, and 7C), or other suitable cross-sectional shape. These configurations can be formed by constructing the arms from cylindrical stock metal or from flat sheet metal, for example.

Any of the locking devices disclosed herein can optionally also include a covering or coating around one or more portions of the device to provide scratch resistance when applied to a motorcycle, anti-slip/anti-skid traction when in contact with the throttle and brake lever, grip for the user, user comfort, aesthetics, and/or other benefits. An exemplary covering 24 is shown in FIGS. 1 and 9 positioned on portions of the female arm 12 and the male arm 14. The covering can comprise a polymeric material, rubber, foam, leather, paint, and/or other materials, and be secured via friction, adhesive, weld, and/or other means. As shown in FIG. 9, once locked into place, the rubber-to-rubber contact (for example) between the throttle 100 and the covering 24 and the knob that is located at the end the motorcycle brake lever 110 can prevent a would-be thief from sliding the lock 10 off to release the brake. FIGS. 5A and 6A shows cross-sections of the arms 12, 14 that illustrate the covering 24.

Any of the locking devices disclosed here can optionally also include a motion detector that can detect motion of the motorcycle when the device is secured to the motorcycle. The motion detector can be encased into, or otherwise coupled to, the arms or lock of the device. The motion detector can be part of a system that includes a battery or other power supply, a recharging port, a sensor that detects motion, and a transmitter that sends a wireless signal indicating sensed motion. The power supply can be rechargeable, such as via a USB cable or other wired charger. Sound and/or light emitting alarm devices can also be included in or coupled to the motion detector to further deter theft.

An exemplary locking device 60, similar to the locking device 50, having a motion detector 62 is shown in FIG. 10. In this example, the motion detector 60 is located in the adjacent to the locking mechanism and built into the housing. In other embodiments, the motion detector can be located elsewhere on the device. The motion detector 60 can comprise a circuit board that includes a low-power consumption motion sensor, a transmitter, and an onboard power supply circuit. The motion detector 62 can be coupled to a micro USB port 64 such that a user can recharge the motion detector 60 by plugging in a micro USB cable into the port 64.

The wireless signal can be transmitted in any form, such as using Bluetooth technology, and can be received by a remote receiver. The receiver can be a mobile computing device, such as a cell phone, tablet, laptop, pager, etc., or a stationary device. The receiver can be coupled or paired to the transmitter such that only signals from a particular transmitter are received by a particular receiver. The receiver can include an application or other software program that generates an alarm or other signal to indicate that the motorcycle has been moved. The receiver can be a mobile phone or the like and the user can download or otherwise install the application or software that specifically allows the user to pair that particular mobile device to a particular locking device, such as using Bluetooth or similar technology. The transmitter can optionally also send a signal to a central monitoring station that monitors many different locking devices, and/or send a signal to police or other authorities to help prevent theft, or interrupt or catch a thief.
