Abstract

A locking system for a treadmill includes a locking mechanism having a locked configuration that prevents rotation of the tread in a fore-aft direction and an unlocked configuration that allows rotation of the tread in the fore-aft direction. The presence sensor and the weight sensor are each configured to detect the user on the treadmill, and the display is configured to receive a code indicative of an input by the user on the treadmill. The controller is configured to move the locking mechanism to the unlocked configuration in response to the controller receiving signals from at least two of the presence sensor, the weight sensor, and the display indicating that the user is on the treadmill, and to move the locking mechanism to the locked configuration in response to receiving signals from both the presence sensor and the weight sensor indicating that the user is not on the treadmill.

Description

Locking and braking system for a treadmill

Technical Field

The present disclosure relates to exercise equipment including motorized treadmills and manual treadmills and improvements thereof.

Background

Exercise treadmills allow a person to walk, jog, run, or sprint on a stationary machine having a moving tread. The treadmill tread may include a continuous belt or slat belt. Once the user of the treadmill has walked down on the tread surface, the tread surfaces of both the motorized treadmill, which uses a motor to move the tread surface, and the manual treadmill, which relies on the user to move the tread surface, continue to move. Once the user continues to operate the treadmill, the moving tread can make it difficult for the user to continue using the treadmill. In addition, other individuals near the moving tread may step on the tread without realizing that the tread is moving. Motorized treadmills and manual treadmills also allow an unauthorized user (such as a child or animal) to step on the tread during or after use by the authorized user. In addition, motorized treadmills and manual treadmills do not provide warning to individuals in the vicinity that the tread is moving.

Motorized treadmills and manual treadmills also often display information to a user using a display screen. Such displays may be ineffective means of communicating information to the user of the treadmill or to the viewer of the user while the user is operating the treadmill.

Disclosure of Invention

One aspect of the present disclosure is a treadmill including a locking system. For example, a locking system for a treadmill including a tread that rotates about a front axle and a rear axle and a side rail on each side of the tread, the locking system comprising: a locking mechanism having a locked configuration in which the locking mechanism prevents rotation of the tread in the fore-aft direction and an unlocked configuration in which the locking mechanism allows rotation of the tread in the fore-aft direction; a controller; a presence sensor in communication with the controller, the presence sensor positioned on the treadmill and configured to detect a user on the treadmill; a weight sensor in communication with the controller, the weight sensor positioned on the side rail and configured to detect a user on the treadmill; and a display positioned on the treadmill and configured to receive a code indicative of an input by a user on the treadmill and transmit the input code to the controller. The controller is configured to move the locking mechanism to the unlocked configuration in response to the controller receiving signals from at least two of the presence sensor, the weight sensor, and the display indicating that the user is on the treadmill, and to move the locking mechanism to the locked configuration in response to the controller simultaneously receiving signals from both the presence sensor and the weight sensor indicating that the user is not on the treadmill.

For example, the presence sensor may be an infrared sensor or a non-contact temperature sensor, and the weight sensor may be a load sensor or a strain gauge for detecting a user by detecting a load.

The locking system may include at least two weight sensors, one on one side rail and the other on the other side rail. The controller is configured to move the locking mechanism to the unlocked configuration in response to a signal from each of the presence sensor, the one weight sensor, and the other weight sensor indicating that the user is on the treadmill.

The controller may receive input from each of the presence sensor, the weight sensor, and the display, compare the input code to a predetermined code, and move the locking mechanism to the unlocked configuration in response to a signal from both the presence sensor and the weight sensor indicating that the user is on the treadmill when the input code matches the predetermined code.

The controller may receive input from the presence sensor and from one of the weight sensor and the display, compare the input code to a predetermined code, and move the locking mechanism to the unlocked configuration in response to a signal from the one of the presence sensor and the weight sensor indicating that the user is on the treadmill when the input code matches the predetermined code.

The controller is also configured to immediately move the locking mechanism to the locked configuration when the controller receives a signal from both the presence sensor and the weight sensor indicating that the user is not on the treadmill.

The controller is further configured to move the locking mechanism to the locked configuration when the controller receives a signal from both the presence sensor and the weight sensor indicating that the user is not on the treadmill and a predetermined period of time has elapsed.

The locking mechanism may include: a locking member; an actuator configured to move a locking member between a locked configuration and an unlocked configuration; and a locking member receiver attached to one of the front and rear axles and configured to receive the locking member when the locking mechanism is in the locked configuration.

The treadmill may be a motorized treadmill with an electric motor to power the movement of the tread. The controller is then further configured to disconnect power to the electric motor prior to moving the locking mechanism to the locked configuration and connect power to the electric motor when the locking mechanism is moved to the unlocked configuration.

As another example, a treadmill includes: a tread that rotates about a front axle and a rear axle; a side rail on each side of the tread; a locking mechanism having a locked configuration in which the locking mechanism prevents rotation of the tread in the fore-aft direction and an unlocked configuration in which the locking mechanism allows rotation of the tread in the fore-aft direction; an indicator on each side rail indicating to a user to step on the side rail on which the indicator is located; a weight measurement sensor configured to detect a weight of a user when the user stands on the two indicators, the weight measurement sensor having a weight sensor located below the respective indicators, wherein the weight sensors are physically connected; a display located on the treadmill; and a controller configured to receive the user's weight from the weight measurement sensor and communicate onto the display.

The treadmill may also include a presence sensor positioned above the tread on the treadmill. The controller is then further configured to move the locking mechanism to the unlocked configuration in response to receiving a signal from the weight measurement sensor indicating that the user is standing on the respective indicator, and to move the locking mechanism to the locked configuration when the weight measurement sensor and the presence sensor indicate to the controller that the user is not on the treadmill.

Also disclosed herein are embodiments of a user-activated system that releases a lock on the treadmill shaft when certain criteria are met. The criteria include one or more of the following: detecting a user on the treadmill with a proximity sensor and a weight sensor; detecting a user on the treadmill with a presence sensor; and receiving a user identification code.

Also disclosed herein are embodiments of a locking system that prevents the tread from moving in any direction when the treadmill is not in use. The locking system may lock the tread immediately, or may lock the tread after a period of time has elapsed. The locking system may be activated based on a signal received from one or both of the weight sensor and the presence sensor.

Also disclosed herein are embodiments of a braking system that assists a user during rest times while the user remains on the treadmill. The braking system may be activated based on signals received from the weight sensor and the presence sensor.

As an example, a braking system for a treadmill including a tread that rotates about a front axle and a rear axle and having non-moving side rails on each side of the tread, the braking system comprising: a brake configured to apply a braking force to one of a front axle and a rear axle; a controller in communication with the brake; and a weight sensor below each side rail, the weight sensor configured to detect a load indicative of a user standing on the side rail, each weight sensor in communication with the controller. The controller is configured to engage the brake when a first signal indicative of the detection of the load is simultaneously received from each of the weight sensors and to release the brake when a second signal indicative of the removal of the load is simultaneously received from each of the weight sensors while the tread is moving.

The treadmill may be a motorized treadmill with an electric motor to power the movement of the tread. The controller is then further configured to disconnect power to the electric motor prior to engaging the brake and reconnect power to the electric motor when the brake is released.

The weight sensor may be one of a strain gauge, a piezoelectric sensor, or a load cell.

The brake system may further include: an indicator on each side rail that indicates to a user to step on the side rail on which the indicator is located; weight measuring sensors including weight sensors positioned below the respective indicators and physically connected to evenly distribute the weight of the user; and a display located on the treadmill, the display configured to show a user's weight on the display when the user is standing on the two indicators.

The controller may be further configured to release the brake before receiving the second signal if a predetermined period of time has elapsed since the brake was engaged.

The controller may be further configured to release the brake before receiving the second signal if a predetermined speed of the tread is reached when the brake is engaged.

The brake may include: a brake member; a brake member receiver attached to one of the front and rear axles; and an actuator, wherein the actuator is in communication with the controller to move the brake member into the brake member receiver and against one of the front axle and the rear axle when a request is received from the controller.

The braking system may also include a presence sensor located on the treadmill and configured to detect the presence of a user on the treadmill. The controller may be further configured to release the brakes when simultaneously receiving a second signal from each weight sensor indicating removal of the load and a signal from the presence sensor indicating the user is on the treadmill.

The braking system may also include a presence sensor located on the treadmill and configured to detect the presence of a user on the treadmill. The controller may also be configured to engage the brakes when simultaneously receiving a first signal from each weight sensor indicating that a load is detected and a signal from the presence sensor indicating that a user is on the treadmill.

Also disclosed herein are embodiments of a weight measurement system for a user of a treadmill that provides the user's weight to the user while the user is on the treadmill.

Also disclosed herein are embodiments of a non-contact temperature sensor that can determine that a user is on a treadmill based on a temperature reading or based on a temperature reading, while reading a user's body temperature and control aspects of the treadmill.

Detailed Description

Devices, systems, and methods for improving the operation of motorized and non-motorized treadmills are described herein. A locking system is described that may be configured to stop rotation of a treadmill tread after a user of the treadmill steps off the treadmill. The locking system may prevent operation of the treadmill until the system determines that the next user is an authorized user. A braking system is described that may be configured to slow the rotation of the tread as a user steps down on the tread and steps on the side rails of the treadmill. The braking system may allow the tread to rotate freely when the system determines that the user has retracted onto the tread. Treadmill lighting systems are also described. The lighting system may alert an individual near the treadmill that the treadmill is operating. The lighting system may also convey information to the user and the viewer of the user, including but not limited to the user's performance or biometric data.

Fig. 1 is a top perspective view of a treadmill 100. The treadmill 100 may include a tread 102, side skirts 104, side rails 106, support members 108, handrails 110, and a display 112. The treadmill 100 may also include one or more sensors, including but not limited to: infrared sensors, weight sensors, heart rate sensors, proximity sensors, or any other user detection or biometric sensors. In the non-limiting example shown, as shown in fig. 1, the treadmill 100 includes a presence sensor 116, a weight sensor 118, and a proximity sensor 120.

The tread 102 is the moving surface traversed by a user operating the treadmill 100 and may include a continuous or segmented belt. In the non-limiting example shown, as shown in FIG. 1, tread 102 includes a plurality of slats. The longitudinal ends of each slat may be attached to respective belts that rotate on fixed bearings (e.g., free-wheeling roller bearings) about the front and rear axles. The slats may be configured to have a space between adjacent slats. In other embodiments, the tread 102 may comprise a continuous rubber band. The tread 102 may be actuated by a motor (motorized treadmill) or may be moved by the force of a user (manual treadmill, also known as non-motorized treadmill). The tread 102 may be supported by a sub-frame (e.g., a rigid metal frame, not shown in fig. 1) such that the tread 102 may include a flat, curved, inclined, or declined shape or orientation. Tread 102 may include any other shape or orientation.

One or more side skirts 104 may be supported by the bottom frame on opposite sides of the tread 102. Each side skirt 104 may include side rails 106 located on an upper surface of the side skirt 104. The side rails 106 may be integral with the side skirt 104 or may be separately located on the side skirt 104. The side rail 106 provides a surface for a user to safely stand on the treadmill 100. For example, a user may stand on the side rail 106 to step on or off the tread 102, or to step on or off the treadmill 100 entirely, while the tread 102 is moving or at rest. The side rails 106 may extend along any length and width of the side skirt 104. Each of the side rails 106 may include a foot pad 122 that specifies one or more portions of the side rail 106 on which a user may stand. The foot pad 122 may be integral with the side rail 106 or may be separately located on the side rail 106. The foot pad 122 may be illuminated by lights located above, around, and/or below the foot pad 122 to indicate where the user is standing on the side rail 106. For example, the outline of the foot may be illuminated from below the side rail 106 using an opaque or transparent plastic material through which an underlying mounted lamp emits light. The foot pad 122 may be illuminated by a light in response to the proximity sensor 120, the presence sensor 116, or an input on the display 112 detecting a user.

The support member 108 may comprise a strut or any other structural member. One end of the support member 108 may be coupled to the bottom frame and/or the side skirt 104, and the other end may be coupled to the armrest 110. The support members 108 provide structural support for the armrests 110 and may be coupled to any portion of the bottom frame and/or the side skirt 104 (e.g., in the middle of the treadmill 100, at either end of the treadmill 100, or at any position therebetween). Any number of support members 108 may be used. The frame 202 may support other components of the treadmill 100, including but not limited to the axle, the side skirt 104, the side rail 106, the support member 108, and/or the handrail 110. The frame 202 may be made of any metal or any other material, and may include one or more structural members.

The armrest 110 is coupled to the support member 108 and provides support to the user while the user is operating the treadmill 100. For example, the user may grasp the armrest 110 to step on or off the tread 102, or to step on or off the treadmill 100 entirely. The armrest 110 supports the display 112, either alone or in combination with other support members. The display 112 may include any screen (e.g., a touch screen) located on the armrest 110. The display 112 may include a non-contact skin temperature sensor 113 that may be configured to measure the temperature of the user while the user is present on the treadmill without the sensor being in contact with the user. Display 112 may display information to a user, including but not limited to: user heart rate, temperature, calories burned by the user, or any other biometric data; distance traveled, distance remaining, exercise duration, exercise time remaining, tread speed, user running pace, or any other user performance information; and/or data associated with another treadmill user.

The treadmill 100 may include one or more systems to improve the functionality of the treadmill 100 and enhance the user's experience. The treadmill 100 may include a locking system configured to prevent rotation of the tread 102 when the treadmill 100 is not in use and to stop rotation of the tread 102 in response to a user stepping off the treadmill 100. The treadmill 100 may additionally include a braking system configured to slow the rotation of the tread 102 when the treadmill 100 is operating but there is no user on the tread 102. These systems may operate in response to receiving signals from the weight sensor 118 and the presence sensor 116.

One or more weight sensors 118 may be positioned such that weight and/or presence is detected while a user is standing on the foot pad 122 and/or the side rail 106. The weight sensor 118 may include a strain gauge, a load sensor, a piezoelectric sensor, or any sensor configured to detect the weight and/or presence of a user. As used herein, a "weight sensor" is any sensor that detects when a load is placed thereon. To actually measure the weight, two weight sensors (such as strain gauges) may be positioned under each foot pad 122 between the underlying frames and connected using the bracket 200 shown in fig. 2. The bracket 200 may be positioned below the foot pad 122 and tread 102 to evenly distribute the weight of the user to the weight sensors 118 while standing on the foot pad 122.

In the non-limiting example of the weight measuring sensor shown in fig. 2 shown, the bracket 200 has two opposing flanges 204 that cover the strain gauges. A plate 206 extends between the flanges 204 to connect the flanges 204. In the non-limiting example shown, the bracket 200 is U-shaped. The flange 204 may be integral with the plate 206. For example, the stent 200 may comprise a one-piece, pre-formed plastic or metal stent. The bracket 200 may also include any configuration and/or orientation relative to the frame 202. The bracket 200 physically connects the strain gauges, thereby distributing the entire weight of the user over the strain gauges.

The weight sensor 118 may measure the weight of the user in response to the user stepping on the foot pad 122 overlying the stepping bracket 200. In some embodiments, in response to a user's request to measure the user's weight (e.g., using display 112), foot pads 122 may be illuminated by lights to indicate that the user is standing on foot pads 122. The user's weight may also be automatically measured in response to the weight sensor 118 detecting the user's presence on the foot pads 122. The user's weight may be displayed by display 112.

Additionally and/or alternatively, the weight sensors 118 may detect the presence of a user on the foot pads 122 and/or the side rails 106. Additional weight sensors 118 may be positioned along the length of each side rail 106 below the side rail 106 to detect presence. In response to the weight sensor 118 detecting the presence of a user on the foot pad 122 and/or the side rail 106, the treadmill 100 may be enabled by a controller (described later with respect to fig. 3). The treadmill 100 may also be deactivated by the controller in response to the weight sensor 118 detecting that no user is present on the foot pad 122 and/or the side rail 106.

One or more of the presence sensors 116 may be located on any portion of the support member 108, the armrest 110, or the display 112. The presence sensors 116 may include infrared sensors, ultrasonic sensors, LED linear light sensors, or any other sensor configured to detect the presence of a user on the treadmill 100 (e.g., standing between the support members 108, standing on the tread 102, side rails 106, and/or foot pads 122). The presence sensor 116 is positioned so that the presence of a person near, but not on, the treadmill 100 will not be detected. The presence sensor 116 and the weight sensor 118 may operate together to detect the presence of a user on any portion of the treadmill 100.

In one example, the locking system may be a user-activated system and method that includes a weight sensor 118, a presence sensor 116, and a lock 316 (described later with respect to fig. 3) below the foot pad 122 and the side rail 106. The user initiated method includes the user approaching the treadmill 100 with the intent of using the treadmill 100 not currently in use. If electrically powered, the power supply will be turned off. To support use of the treadmill 100, a user steps on the foot pads 122 or the side rails 106 to activate the weight sensors 118 that detect the presence of the user. Additionally, the presence sensor 116 detects that the user is on an area of the treadmill 100 where the desired use can be inferred. The non-contact temperature sensor 113 may also be used as the presence sensor 116 because detecting a temperature equal to the temperature of a person would indicate that the user is present in the area of the treadmill where use can be initiated. The presence detected by one or both of the weight sensor 118 and the presence sensor 116 may initiate the unlocking of a lock 316 that, when in a locked position, prevents the tread 102 from rotating in any direction. Additionally, the user-initiated system and method may require the user to enter a code prior to unlocking the lock 316, as will be described in more detail below. If a person (such as a child) or animal (such as a pet) is on the treadmill 100 for reasons other than use, the user-activated system and method prevents the tread 102 from moving. This may be particularly important for treadmills with non-motorized slats, as for example fingers or toes may be caught by the slats and may move even if the tread is not intended.

FIG. 3 is an illustration of the internal components of the treadmill 100, including the lock and braking system. In the non-limiting example shown, the frame 202 includes two side members that support the side skirt 104 and a plurality of cross members that extend between the side members. The support members 108 are coupled to the side members of the frame 202. The bracket 200 extends between two side members of the frame 202. The weight sensor 118 is positioned on a side member of the frame 202 below the flange 204 of the bracket 200. Additional weight sensors 118 are positioned on the side members of the frame 202 below the side skirts 104. The treadmill 100 may include any number of weight sensors.

The treadmill 100 may include a front axle 300 and a rear axle 302. The front axle 300 and the rear axle 302 may be coupled to the frame 202 and may rotate relative to the frame 202 via bearings 312. Bearings 312 may allow for bi-directional or uni-directional rotation of front axle 300 and rear axle 302. Unidirectional rotation allows the tread 102 to rotate in only one direction and prohibits the tread 102 from moving "backwards" in the opposite direction.

The front axle 300 and the rear axle 302 may include a front axle drum 304 and a rear axle drum 306, respectively. The front and rear axle drums 304, 306 may be fixed to the front and

rear axles

300, 302, respectively, such that the front and rear axle drums 304, 306 rotate with the front and rear axles. The front axle drum 304 and the rear axle drum 306 may enlarge the diameter of the front axle 300 and the rear axle 302, respectively. The tread 102 may extend around the front axle drum 304 and the rear axle drum 306 such that rotation of the front axle drum 304 and/or the rear axle drum 306 results in rotation of the tread 102. In embodiments where the treadmill 100 is motorized, when activated, an electric motor (not shown) may be coupled to and may rotate the front axle 300, the rear axle 302, the front axle drum 304, and/or the rear axle drum 306. The electric motor may be coupled to the front axle 300, the rear axle 302, the front axle drum 304, or the rear axle drum 306 via a belt or any other known means. For example, a belt may be attached to the tread on either side of the tread, the belt rotating about a wheel 338 turned by the axle/drum. The electric motor may be coupled directly to the frame 202, or may be coupled to the frame 202 via a bracket or any other intermediate component.

In embodiments where the treadmill 100 is non-motorized, the treadmill 100 may include a generator 308. The generator 308 may convert the rotation of the front axle 300, rear axle 302, front axle drum 304, and/or rear axle drum 306 into electrical energy that is stored in the battery 310. The generator 308 may include a dc generator, a magneto, or any other device configured to convert the rotation of a shaft or shaft drum into energy for powering the battery 310. The generator 308 may be coupled to the front shaft 300, the rear shaft 302, the front shaft drum 304, or the rear shaft drum 306 via a belt or any other known means. The generator 308 may be coupled directly to the frame 202, or may be coupled to the frame 202 via a bracket or any other intermediate component.

The battery 310 may comprise an 12/24VDC battery, but may also comprise one or more batteries of any type operating at any voltage. The battery 310 may be coupled directly to the frame 202, or may be coupled to the frame 202 via a bracket or any other intermediate component. In other embodiments, the battery 310 may not be coupled to the frame 202. The battery 310 may be external to the treadmill 100 (e.g., the battery 310 may be located near the treadmill 100 or in a space defined by the treadmill 100 below the treadmill 100). The battery 310 may include a charging port to receive power from an external power source. If the charge of the battery 310 is depleted, the charging port may be used. The battery 310 may power any of the electrical components described herein, including but not limited to any lights, sensors, displays, or controllers. Additionally and/or alternatively, the treadmill 100 may include a power cord configured to electrically connect to an external power source (e.g., an electrical outlet). The power received by the power cord may be used to power the described electrical components.

The treadmill 100 may include a controller 314. The controller 314 may receive data from the presence sensor 116, the weight sensor 118, the proximity sensor 120, and/or any other sensor. The controller 314 may also be in electrical communication with any of the other described electrical components, including but not limited to the display 112, the generator 308, and the battery 310. The controller 314 may be coupled to any portion of the frame 202, but may also be coupled to any portion of the treadmill 100. The controller 314 may be coupled to the frame 202 via a bracket or any other intermediate component, or may be coupled directly to the frame 202 or a surface of the battery 310 (e.g., a top surface of the battery 310).

The lock 316 is configured to automatically stop rotation of the tread 102 in any direction when a user is not present on the treadmill 100 (e.g., not present on the tread 102 or the side rail 106). Once the lock 316 is engaged, such as when a user steps down the treadmill, the lock 316 may prevent the tread 102 from rotating in any direction until the user's presence is again identified with the weight sensor, the infrared sensor, and in some embodiments the entry of an identification code.

The lock 316 may include a locking member 318, a locking member receiver 320, an actuator 322, and an actuator bracket 324. In the non-limiting example shown, as shown in fig. 3, the locking member receiver 320 is coupled to the rear axle drum 306 and rotates with the rear axle drum 306. The locking member receiver 320 may be coupled to the rear axle drum 306 using keys, screws, nuts, bolts, rivets, welding, or any other attachment means. In other embodiments, the locking member receiver 320 may be coupled to the front axle 300, the front axle drum 304, or the rear axle 302. The locking member receiver 320 is configured to receive the locking member 318. The locking member receiver 320 may include a cam or any other device capable of engaging the locking member 318 to inhibit rotation of the front axle 300, the rear axle 302, the front axle drum 304, and/or the rear axle drum 306 in any direction.

The actuator 322 is configured to move the locking member 318 between the locked and unlocked positions. The actuator 322 may include any type of spring, motor, solenoid, electric cylinder with an integrally formed motor, or any other device capable of moving the locking member 318 to engage the locking member receiver 320. The actuator 322 is coupled to the actuator bracket 324 using any of the described attachment means. The actuator bracket 324 is coupled to the frame 202 using any of the described attachment means. In other embodiments, the actuator 322 may be directly coupled to any portion of the frame 202.

The actuator 322 is configured to move the locking member 318 to engage the locking member receiver 320. The locking member 318 may include any bolt, rod, plate, piston, or any other device configured to engage the locking member receiver 320 to inhibit rotation of the front axle 300, rear axle 302, front axle drum 304, and/or rear axle drum 306 in any direction.

To move the locking member 318 to the locked position, the actuator 322 moves the locking member 318 toward the locking member receiver 320 until the locking member 318 engages the locking member receiver 320. In the locked position, contact between the locking member 318 and the locking member receiver 320 inhibits rotation of the locking member receiver 320 and the rear axle drum 306 in any direction. Stopping rotation of the axle drum 306 results in stopping rotation of the tread 102. In the unlocked position, the locking member 318 does not contact the locking member receiver 320 and the rear axle drum 306 are allowed to rotate freely. A plurality of locks 316 may be used to stop rotation of the front axle 300, the rear axle 302, the front axle drum 304, or the rear axle drum 306. The lock 316 may be used in embodiments where the treadmill 100 is powered or unpowered.

Fig. 4 is a side view of an embodiment of a lock 400 that may be used as the lock 316, and may include features similar to those of the lock 316 unless otherwise described. The actuator bracket 402 includes a first plate 404 and a second plate 406. The first plate 404 may be disposed on one side of any portion of the frame 202, while the second plate 406 may be disposed on an opposite side of that portion of the frame 202. Nuts and screws are used to couple the first plate 404 and the second plate 406, but any other described attachment means may be used. Although the actuator bracket 402 is not limited to the structure shown in fig. 4, any intermediate component of any shape and size that couples the actuator to the frame 202 may be included.

The lock 400 includes a toothed cam 408 coupled to the rear axle drum 306 such that the toothed cam 408 rotates with the rear axle drum 306. The toothed cam 408 is coupled to the rear axle drum 306 using a key 409. Toothed cam 408 may comprise two halves coupled via flange 412 and a fastener such as a nut and bolt. The toothed cam 408 may include side walls on opposite sides of the toothed cam 408. Toothed cam 408 is shown as having four teeth, but may include any number of teeth. The teeth of the toothed cam 408 may have any shape. In other embodiments, any type of cam having any shape may be used. The lock 400 includes a solenoid 414 (e.g., a two-state solenoid) that is coupled to the first plate 404 of the actuator bracket 402 using screws, bolts, or any other described attachment means. The solenoid 414 may include features similar to those of the actuator 322, unless otherwise described. In other embodiments, any other actuator may be used. The lock 400 includes a bolt 416 coupled to a solenoid 414. Unless otherwise described, the bolt 416 may include features similar to those of the locking member 318.

The solenoid 414 is configured to move the bolt 416 between the locked and unlocked positions. To move the bolt 416 to the locked position (shown in phantom), the solenoid 414 moves the bolt 416 toward the toothed cam 408 until the bolt 416 engages the teeth of the toothed cam 408. The engagement between the bolt 416 and the teeth of the toothed cam 408 stops the toothed cam 408 from rotating in either direction. Stopping the rotation of the toothed cam 408 stops the rotation of the rear axle drum 306, which stops the rotation of the tread 102. To move the bolt 416 to the unlocked position, the solenoid 414 is configured to move the bolt away from the toothed cam 408 until the bolt 416 does not contact the toothed cam 408, thereby allowing the toothed cam 408 to rotate freely. In embodiments where the solenoid 414 is a two-state solenoid, once the solenoid 414 is energized by the battery 310 to move the bolt 416 to the locked position, the bolt 416 remains in the locked position until the solenoid 414 is energized again. In such embodiments, the bolt 416 may remain in the locked position even if power is not supplied to the solenoid 414 or any other component of the treadmill 100. Similarly, once the solenoid 414 is energized by the battery 310 to move the bolt 416 to the unlocked position, the bolt 416 remains in the unlocked position until the solenoid 414 is energized again.

The lock 316 (or lock 400) may be in electrical communication with the controller 314 and may operate in conjunction with the weight sensor 118 and presence sensor 116 as a user-initiated system and method, as described below. When not in use, the treadmill 100 will be locked, i.e., the lock 316 will be in a locked position. For example, if during operation of the treadmill 100, the controller 314 determines that the user is not present on the tread 102 and not present on the side rail 106, the controller 314 is configured to engage the lock 316 as previously described to prevent movement of the tread 102 in any direction. The engagement of the lock 316 may be momentary, i.e., once both

sensors

118, 116 fail to detect a user. The engagement of the lock 316 may occur after a period of time. In embodiments where the treadmill 100 is motorized, the controller 314 may disconnect (e.g., electrically disconnect) power to an electric motor (not shown) prior to engaging the lock 316. In embodiments where the treadmill 100 is non-powered, the battery powers the actuator to engage the lock 316. Prior to engaging the lock 316 or in response to engaging the lock 316, the display 112 may generate a notification indicating to the user that the lock 316 is to be engaged and/or has been engaged.

Once the controller 314 has engaged the lock 316, the lock 316 remains engaged until the controller 314 determines that one or more activation criteria have been met. The enablement criteria can include one or more combinations: the presence of the user on the foot pads 122 is detected by the weight sensors 118; the presence of a user on the two side rails 106 is detected by the weight sensors 118; detecting the presence of a user on any portion of the side rail 106 via the weight sensor 118; a user is detected by the presence sensor 116; determining, by the controller 314, that the weight of the user detected by the weight sensor 118 meets or exceeds a threshold weight; and/or an identification code entered by an authorized user (e.g., using display 112).

In embodiments where the enablement criteria includes authorization of the identification code, the controller 314 may verify the identification code by: in response to receiving the user's identification code, the identification code is compared to a list of authorized codes stored locally on the treadmill 100 (e.g., in a memory included in the controller 314) or remotely on a server device in communication with the treadmill 100 (e.g., in communication with the controller 314). In response to determining that the identification code entered by the user matches one of the authorized codes, the controller 314 may release the lock 316. The identification code prevents an unauthorized user from using the treadmill 100. In some embodiments, no identification code is required. Additionally and/or alternatively, the treadmill 100 may use biometric information (e.g., fingerprint data, voice data, or facial recognition data) detected by any sensor located on the treadmill 100 to verify the identity of the user.

Fig. 5A is a flow chart of an embodiment of a locking system and process 500 that initiates use of the treadmill 100 with the lock 316 in the engaged position. It is contemplated that one or both of the weight sensor or the presence sensor may detect a user on the treadmill and turn on the display. The display may direct the user to stand on the foot pad 122 to unlock the tread. In operation 502, the controller 314 receives a signal from the weight sensor 118 indicating that the presence of a user on the foot pad 122 is detected. In operation 504, the controller 314 determines whether the weight of the user meets or exceeds a threshold weight in response to the weight sensor 118 detecting the presence of the user. The threshold weight may be programmed into the controller or may be set by the owner or operator. As one example, the weight threshold reduces the chance that a child who should not use the treadmill will be able to unlock the treadmill. In optional operation 506, the controller 314 receives the identification code and determines whether the identification code is an authorized code. It is contemplated that the display may present a prompt to the user to enter his or her identification code before the user stands on the foot pad 122 or once the user stands on the foot pad 122.

In operation 508, the controller 314 initiates release of the lock 316 in response to determining that the user is present on the footpad 122 and is equal to or exceeds the threshold weight and optionally enters an appropriate identification code, thereby freeing the user to use the treadmill 100. The release is powered by the battery of the non-motorized treadmill, and for motorized treadmills, by the motor. For example, referring to lock 400 shown in fig. 4, controller 314 may activate solenoid 414 to move bolt 416 away from toothed cam 408 to the locked position. At operation 508, the controller 314 may also initiate the activation of any other electronic components of the treadmill 100, including but not limited to any display, lights, motors, or controllers. The activation system will no longer be required until the lock is in its locked position.

Fig. 5B is a flow chart of another embodiment of a locking system and process 520 that initiates use of the treadmill 100 with the lock 316 in the engaged position. It is expected that two or more criteria, including weight sensors, presence sensors, and identification codes, will be required to unlock the locking system. It is contemplated that either or both of the weight sensor or the presence sensor may detect the user on the treadmill and turn on the display. It should be noted that the display, controller and sensors are powered by batteries in the non-motorized treadmill or may be plugged in to operate these devices. For safety, the display may guide the user to stand on the side rails. In operation 522, the controller 314 receives a signal from the at least one weight sensor 118 on the at least one side rail indicating that the presence of a user is detected. Alternatively, the system may require the controller 314 to receive a signal from at least one weight sensor 118 on each side rail that indicates the presence of the user, i.e., the user is riding on the tread. In operation 524, the controller 314 may additionally request to receive a signal from the presence sensor 116 indicating that a user is detected in the region of the tread and/or side rail, suggestive of an intent to use the treadmill. In operation 526, the controller 314 may additionally require receipt of an identification code, which the controller determines if the identification code is an authorized code. It is contemplated that the display may present a prompt to the user to enter his identification code before or once the user stands on the foot pad 122.

In operation 528, the controller 314 initiates release of the lock 316 in response to determining that the user is present on the treadmill and has entered the appropriate identification code, thereby freeing the user to use the treadmill 100.

FIG. 6 is a flow chart of a process 600 of engaging the lock 316 when the lock has been released and the treadmill is in use. In operation 602, the controller 314 does not receive any signal from any of the weight sensors 118 associated with the foot pad 122 and the side rail 106. In operation 604, the controller 314 does not receive any signals from any presence sensors 116. In operation 606, the controller 314 determines that no user is present on the treadmill 100 in response to the absence of signals from any weight sensors 118 and any presence sensors 116.

In embodiments where the treadmill 100 is a motorized treadmill, the process 600 may include an operation 608. In operation 608, the controller 314 disconnects the electric motor from power in response to determining that no user is present on the treadmill 100. The controller 314 may initiate engagement of the lock 316 in response to determining that no user is present on the treadmill 100 and in response to disconnecting power to the electric motor. In embodiments where the treadmill 100 is a non-motorized treadmill, the process 600 proceeds from operation 606 to operation 610. In operation 610, the controller 314 may initiate engagement of the lock 316 in response to determining that no user is present on the treadmill 100. After expiration of the threshold time period, the controller 314 may initiate engagement of the lock 316. In one example, the controller 314 may initiate engagement of the lock 316 in response to determining that no user is present on the treadmill 100 and determining that a threshold time period has expired. In response to determining that no user is present on the treadmill 100, the threshold time period begins. The threshold time period may vary and may be set by the user of the treadmill or may be predetermined. The lock 316 remains engaged until the aforementioned actuation process is completed. The controller 314 may disable the display 112 and/or other electronic components of the treadmill 100 in response to determining that no user is present on the tread 102 and no user is present on the side rail 106.

Referring back to fig. 3, treadmill 100 may include brakes 326. The brake 326 is configured to slow the rotation of the tread 102 in response to the user stepping down on the tread 102 and up the side rail 106 (e.g., while the user is at rest). By slowing the rotation of the tread 102 rather than stopping completely while the user is resting on the side rail 106, the user can back onto the tread 102 and continue to use the treadmill more easily. Additionally and/or alternatively, the brake 326 may stop rotation of the tread 102 for a period of time if the user stands on the side rail 106 for an extended period of time.

As non-limiting examples, during use of the treadmill 100, a user may step on the side rail 106 and step down on the tread 102 to drink something, receive a phone call, talk with a person present, or rest. When the user steps on the side rail 106 while the tread 102 is moving, the brake 326 engages to slow the tread 102 so that when the user is ready to back on the tread 102, the tread 102 moves at a lower, more manageable pace than when the user is walking down. If treadmill 100 is a motorized treadmill, power to the electric motor will be temporarily disconnected when brake 326 is applied. The brake 326 may be applied until the user retracts onto the tread 102, i.e., no weight sensor 118 on the side rail 106 detects the user's weight. The user will then raise the tread 102 to the desired rotational speed under the user's own power (if the treadmill 100 is unpowered) or by using the tread speed control on the display 112 (if the treadmill 100 is powered). If the user remains off the tread 102 and resting on the footpad 122 for a period of time, the brake 326 may be released when a threshold time or speed is reached, allowing the tread 102 to slow down further under its own momentum. Alternatively, the brake 326 may be applied until the early stage when the tread 102 stops or the user backs up on the tread 102.

The brake 326 may include a brake actuator 328, a brake actuator bracket 330, a brake member 332, and a brake member receiver 334. In the non-limiting example shown, the brake member receiver 334 is coupled to and rotates with the front axle drum 304. The brake member receiver 334 includes a channel 336 having an inner profile that corresponds to the outer profile of the brake member 332. The brake member receiver 334 may be coupled to the front axle drum 304 using keys, screws, nuts, bolts, rivets, welding, or any other attachment means. In other embodiments, the brake member receiver 334 may be coupled to the front axle 300, the rear axle 302, or the rear axle drum 306. The brake member receiver 334 is configured to receive the brake member 332. The brake member receiver 334 may include a ring coupling or any other device configured to receive the brake member 332 to slow rotation of the front axle 300, the rear axle 302, the front axle drum 304, and/or the rear axle drum 306. A plurality of brakes 326 may be used to slow the rotation of the front axle 300, rear axle 302, or rear axle drum 306. The brake 326 may be used in embodiments where the treadmill 100 is powered or unpowered.

The brake actuator 328 is configured to move the brake member 332 between a braking position and a non-braking position. The brake actuator 328 may include any type of spring, motor, solenoid, electric cylinder with an integrally formed motor, or any other device capable of moving the brake member 332 to engage the brake member receiver 334. The brake actuator 328 is coupled to the brake actuator bracket 330 using any of the described attachment means. The brake actuator bracket is coupled to the frame 202 using any of the described attachment means. In other embodiments, the brake actuator 328 may be coupled directly to any portion of the frame 202.

The brake actuator 328 is configured to move the brake member 332 to engage the brake member receiver 334. Brake member 332 may include brake pads, calipers, or any other device configured to engage brake member receiver 334 to slow rotation of front axle 300, rear axle 302, front axle drum 304, and/or rear axle drum 306.

To move the brake member 332 to the braking position, the brake actuator 328 moves the brake member 332 toward the brake member receiver 334 until the brake member 332 engages the brake member receiver 334. In the braking position, friction between the brake member 332 and the brake member receiver 334 reduces the rotational speed of the front axle drum 304. In the non-braking position, the brake member 332 does not engage the brake member receiver 334 and the front axle drum 304 is allowed to rotate freely. The reduction in the rotational speed of the front axle drum 304 results in a reduction in the rotational speed of the tread 102. In some embodiments, the brake member receiver 334 is not required, and the brake member 332 directly engages the front axle 300, the rear axle 302, the front axle drum 304, and/or the rear axle drum 306.

Fig. 7 is a side view of an embodiment of a brake 700 that may be used as brake 326 and may include features similar to those of brake 326 unless otherwise described. In the non-limiting example shown, the brake 700 includes a brake actuator bracket 702 that includes a first plate 704 and a second plate 706. The first plate 704 may be disposed on one side of any portion of the frame 202, while the second plate 706 may be disposed on an opposite side of that portion of the frame 202. Nuts and screws are used to couple the first plate 704 and the second plate 706, but any other described attachment means may be used. Although the brake actuator bracket 702 is not limited to the structure shown in fig. 7, any intermediate component of any shape and size that couples the brake actuator to the frame 202 may be included.

The brake 700 includes a solenoid 708 (e.g., a two-state solenoid) that is coupled to the first plate 704 of the brake actuator bracket 702 using screws, bolts, or any other described attachment means. Unless otherwise described, solenoid 708 is an example of a brake actuator 328. Brake 700 includes a brake member 710 having a bolt 712, a brake pad retainer 714, and a brake pad 716. The brake member 710 may include features similar to those of the brake member 332, unless otherwise described. Bolt 712 is coupled to brake pad retainer 714. Brake pad retainer 714 may be integral with bolt 712 or may be separately coupled to bolt 712. The brake pad retainer 714 includes a curved shape. A brake pad 716 having a curved shape is coupled to brake pad retainer 714. Brake pad 716 may be made of ceramic or any other suitable material. In other embodiments, brake 700 may not include brake member 710, but may include any device configured to engage a brake member receiver.

The brake 700 includes an annular coupling 718 that extends around the front axle drum 304. Unless otherwise described, the ring coupling 718 may include features similar to those of the brake member receiver 334. The ring coupling 718 may include two halves coupled via a flange 720 and fasteners such as nuts and bolts. The ring coupling 718 is coupled to the front axle drum 304 using keys 722. Annular coupling 718 defines a channel 724 having an inner profile shaped to correspond to an outer profile of brake pad 716. In other embodiments, the brake 700 may not include the annular coupling 718, but may include any device configured to receive a braking member (e.g., bolt 712) to slow the axle or axle drum of the treadmill 100.

The solenoid 708 is powered by the battery 310 for the non-motorized treadmill and moves the braking member 710 between the braking and non-braking positions. In the braking position, brake pad 716 contacts the inner surface of channel 724 and friction between brake pad 716 and annular coupling 718 slows rotation of front axle drum 304. In the non-braking position of the braking member 710, the brake pads 716 do not contact the annular coupling 718 and allow the front axle drum 304 to rotate freely. In embodiments where the solenoid 708 is a two-state solenoid, once the solenoid 708 is energized by the battery 310 to move the braking member 710 to the braking position, the braking member 710 remains in the braking position until the solenoid 708 is energized again. Similarly, once the solenoid 708 is energized by the battery 310 to move the braking member 710 to the non-braking position, the braking member 710 remains in the braking position until the solenoid 708 is energized again.

The brake actuator 328 may be in electrical communication with the controller 314 and may operate in conjunction with the weight sensor 118 and the presence sensor 116, as described below. Presence sensors 116 located on the support members 108 and/or on the armrest 110 are configured to detect the presence of a user on the treadmill 100 (e.g., a user standing on any portion of the tread 102 or side rail 106). The weight sensor 118, which is located below the side rail 106, is configured to detect whether a user is present on any portion of the side rail 106 and/or foot pad 122. In response to the controller 314 determining that a user is present on the tread 102 and that the user is not present on either of the side rails 106, the brake 326 remains released, allowing the tread 102 to rotate freely.

If, during operation of the treadmill 100, the controller 314 determines that a user is present on both side rails 106 (e.g., simultaneously) and that the user is not present on the tread 102 (e.g., the user has stepped down on the tread 102 and stepped up on one or both of the side rails 106), the controller 314 may engage the brake 326 to slow rotation of the tread 102 as previously described. Optionally, controller 314 may be configured to apply brakes 326 only when the user is standing on both foot pads 122 (which indicates a desire to apply the brakes). The display may indicate to the user during use: stepping on the foot pad 122 will apply the brakes during the rest period. In response to engaging brake 326, display 112 may generate a notification indicating to the user that brake 326 is engaged. The brake 326 may slow the rotation of the tread surface 102 to a threshold speed, which may be predetermined or may be set by the user. In response to the controller 314 determining that the tread 102 is rotating at the threshold speed, the controller 314 may fully or partially release the brake. After the brake 326 has engaged, and in response to the controller 314 determining that the user is present on the tread 102 and not present on the side rail 106 (e.g., the user has stepped down on the side rail 106 and returned to the tread 102), the controller may release the brake 326, allowing the tread 102 to rotate freely. In embodiments where treadmill 100 is motorized, controller 314 may disconnect (e.g., electrically disconnect) power to the electric motor prior to engaging brake 326 and reconnect power when brake 326 is released.

FIG. 8 is a flow chart for operating braking system 800 while tread 102 is moving. At operation 802, the controller 314 receives a signal from the weight sensor 118 indicating the presence of a user on the two side rails 106, such as a user riding on the tread 102. At operation 804, the controller 314 may additionally receive a signal from the presence sensor 116 indicating the presence of a user in the area of the treadmill 100 indicating use. In operation 806, the controller 314 determines that the user is "resting" and that the brake 326 should be activated. In embodiments where the treadmill 100 is a motorized treadmill, the process 800 may include operation 808. In operation 808, the controller 314 disconnects the electric motor from power in response to determining that a user is present on the two side rails 106. In embodiments where the treadmill 100 is a non-motorized treadmill, the process 800 proceeds from operation 806 to operation 810.

At operation 810, controller 314 initiates engagement of brake 326. For example, referring to brake 700 shown in fig. 7, controller 314 may initiate movement of brake member 710 such that brake pad 716 contacts annular coupling 718. In some embodiments, the controller 314 may initiate engagement of the detents 326 in response to determining that a user is present on any portion of each side rail. In other embodiments, the controller 314 may initiate engagement of the brake 326 in response to the presence of a user on the footpad 122. Additionally and/or alternatively, the controller 314 may activate engagement of the brake 326 in response to the tread 102 reaching a maximum speed. The maximum speed may be set by the user or may be predetermined.

At operation 812, the controller 314 receives a signal from the weight sensor 118 indicating that a user is not present on any of the side rails 106 (e.g., the controller detects that no signal is received from any weight sensor 118 on any of the side rails 106). At operation 814, the controller receives a signal from the presence sensor (i.e., a signal to continue receiving the presence of the user) indicating the presence of the user in the area of the treadmill 100 to indicate use. At operation 816, the controller determines that the user is returning to the tread 102 to use the treadmill 100. At operation 818, the controller 314 initiates release of the brake 326 in response to determining that a user is present on the tread surface 102. For example, referring to brake 700 shown in fig. 7, controller 314 may activate brake member 710 to move such that brake pad 716 does not contact annular coupling 718. The controller 314 may also release the brake 326 after a predetermined period of time has elapsed since the brake 326 was engaged while the user was still on the side rail. The controller 314 may also release the brake 326 when a predetermined speed of the tread is reached while the user is still on the side rail. The predetermined speed may be zero or any other speed, but is typically the speed at which the user can easily and safely step on the tread to begin using the treadmill after rest.

Treadmill 100 may include lights and lighting systems configured to provide information to the user and/or others (e.g., to alert others in the vicinity that treadmill 100 is operating).

Referring back to fig. 1, one or more of the proximity sensors 120 may be located on one or more of the side skirts 104. For example, one or more proximity sensors 120 may be located on the side surfaces of the side skirt 104 such that the proximity sensors 120 are spaced around the periphery of the treadmill 100. Additionally and/or alternatively, the proximity sensor may be located on any other portion of the treadmill 100, including but not limited to the support member 108 or the armrest 110. The proximity sensor 120 may include one or more infrared sensors, ultrasonic sensors, LED linear light sensors, or any other sensor configured to detect the presence of a person, animal, or object approaching the treadmill 100. For example, the proximity sensor 120 may be configured to detect the presence of anyone within a predetermined radius (e.g., 20 inches to 48 inches) of the proximity sensor 120. The controller 314 may receive a signal from the proximity sensor 120 indicating that a user or another person is detected approaching the treadmill 100.

By way of non-limiting example, when the controller 314 receives a signal from at least one of the proximity sensors 120 and the treadmill is not in use, the controller may activate the display upon receiving the signal and the display may provide steps related to the user's activation of using the treadmill. When the controller 314 receives a signal from at least one of the proximity sensors 120 and the treadmill 100 is in use, the display may alert the user that the treadmill is being approached.

The treadmill 100 may include peripheral lights 124 configured to illuminate an area on the floor around the treadmill 100, for example, to alert an approaching person that the treadmill 100 in use is approaching (i.e., the tread 102 is moving). The peripheral lights 124 may be located on or below the side skirt 104, side rail 106, or armrest periphery 110, and may include LED lights, lasers, projectors, or any other light source. The peripheral lights 124 may be any color and may be illuminated according to any predetermined or user-customized setting (e.g., blinking). The peripheral lights 124 may also change color according to any predetermined or user-customized setting. The lights 124 may project any symbol, word, pattern, or image onto the surrounding area in any configuration or orientation. By way of non-limiting example, the perimeter lights 124 may form a light wall 126 on the floor around the treadmill 100 to alert an approaching person that the treadmill 100 is in use. The light wall may be spaced apart from the treadmill 100, such as from 10012 inches to 24 inches from the treadmill, and may partially or completely surround the treadmill 100. The peripheral lights 124 may be, for example, yellow or red, and are typically used to indicate reminders, such as to give way or stop.

The peripheral lights 124 may operate in conjunction with the controller 314 and other components of the treadmill 100, as described below. In response to the controller 314 determining that a subject is present within a predetermined radius of the treadmill 100 in use (e.g., in response to the proximity sensor 120 detecting the presence of an approaching person), the controller 314 may activate the peripheral lights 124 to illuminate the area surrounding the treadmill. In response to the proximity sensor 120 detecting that a person is approaching the treadmill 100 (e.g., approaching from the side or from the back of the treadmill 100), the display 112 may generate a notification for the user to indicate to the user the presence and location of the approaching person relative to the treadmill 100.

Controller 314 may activate peripheral light 124 to illuminate the area around the treadmill and/or may change the color of peripheral light 124 in response to engagement of brake 326 or in response to engagement of lock 316. For example, the peripheral light 124 may not be enabled when the lock 316 is engaged.

One or more projectors 114 may be located on any portion of the treadmill 100, including but not limited to any portion of the armrests 110 (e.g., inside the armrests 110), the support members 108, and/or the side skirts 104. The projector 114 may be configured to project an image onto a projection area 115. The projected area 115 may include any area near the treadmill (e.g., floor, wall, or ceiling). The image may include any previously described biometric data and/or performance data associated with the user or another treadmill user. For example, the projector 114 may project biometric data or user performance data on a floor near the treadmill 100 for viewing by a referee during a game. Additionally and/or alternatively, the projector 114 may project advertising or marketing information, such as a company logo. Projector 114 may project data onto any surface or surfaces in the vicinity of treadmill 100 in response to commands issued by a user. In response to determining that a user is present near treadmill 100, controller 314 may enable projector 114.

Treadmill 100 may include a lighting system configured to emit light through the tread. The lighting system may alert the user and other individuals that the treadmill 100 is in an operating state, may alert individuals in the vicinity of the treadmill 100 not to approach the treadmill 100, and may convey biometric information or performance information to the user or observer (such as a referee in a game).

As shown in fig. 1, the tread 102 may be formed from a plurality of slats. The slats are configured to form a surface on which a user can exercise and are positioned next to adjacent slats to simulate a continuous belt, with little space between adjacent slats. The lighting system includes a light positioned under a slat on which a user stands. The light is located in a cavity defined at the top and bottom by the tread 102 rotating on the front axle 300 and the rear axle 302. The tread surface is the surface facing away from the cavity and includes the surface on which the user exercises. The lock 316, brake 326, front axle 300, rear axle 302, front axle drum 304, and rear axle drum 306 may be located in the cavity.

The lights may be configured to emit light away from the cavity along any length of the tread 102 and through one or more spaces between the slats. The lights may comprise LEDs, neon lights, or any other type of light, and may be included in a light strip or cord. The lamp may also include one or more integrated circuits.

The lighting system may also include a controller 314 or any other controller configured to control the lamps. The lights may be in communication (e.g., wired or wireless) with the controller 314 or any other controller. The lights may operate in conjunction with the controller 314 and other components of the treadmill 100. The controller 314 may control the activation, deactivation, color, brightness, and/or frequency of the light. The controller 314 may be configured to control at least one of the color, brightness, or frequency of illumination of the light in response to receiving a signal from the biometric sensor shown in fig. 1. The biometric sensor may include one or more of a non-contact skin temperature sensor 113, a heart rate sensor, a weight sensor 118, or any other sensor configured to detect biometric information associated with a user. The biometric sensor may be located on any portion of the treadmill 100. The controller 314 may also be configured to control at least one of the color, brightness, or frequency of illumination of the lights in response to calculating the user's biometric information based on signals received from the biometric sensor, including but not limited to calories burned or body mass index. The biometric sensor may detect biometric information data associated with the user in response to a request from the user. Additionally and/or alternatively, the biometric sensor may detect biometric information associated with the user in response to the weight sensor 118 detecting the presence of the user on the foot pad 122 and/or the side rail 106.

Controller 314 may control at least one of the color, brightness, or frequency of illumination of the lights based on user-associated performance data including, but not limited to, distance traveled, distance remaining, exercise duration, exercise time remaining, tread speed, user running pace, or any other user performance information; and/or data associated with another treadmill user.

The controller 314 may also activate the lights in response to receiving a signal from the proximity sensor 120 indicating that a user or another individual is present near the treadmill 100. For example, when the treadmill is not in use, the proximity sensor 120 may detect that a person is approaching the treadmill 100 and send a signal to the controller 314 to activate the light. Lights may be activated to invite an approaching person to use the treadmill 100, such as using certain colors or flashing lights. As another example, when the treadmill 100 is in use, the proximity sensor 120 may detect that a person is approaching the treadmill 100 and send a signal to the controller 314 to flash an already enabled light or change the color of the light (such as yellow or red) to alert the approaching person that the tread 102 is moving.

The lights may include one or more sets of lights configured to illuminate different portions of the treadmill 100. For example, the lighting system may include a first set of lights configured to be controlled by the controller 314 to illuminate the front 128 (shown in fig. 1) of the treadmill. The front of the treadmill 100 is associated with a position where the slats are proximate the front axle 300 and pivot about the front axle 300. The lighting system may include a second set of lights configured to be controlled by the controller 314 to illuminate the rear portion 130 (shown in fig. 1) of the treadmill, where the rear portion 130 is opposite the front portion 128. Rear portion 130 is associated with a position where the slats are proximate to rear axle 302 and rotate about rear axle 302. The lighting system may also include a third set of lights configured to illuminate a middle portion 130 (shown in fig. 1) of the treadmill, where the middle portion 132 extends between the front portion 128 and the rear portion 130. The front, rear and middle portions of the treadmill may be illuminated separately by lights in any combination of any color, brightness or frequency of illumination. For example, the controller 314 may be configured to illuminate the front and rear of the treadmill 100 with a first color (e.g., yellow) and the middle with a second color (e.g., green). By illuminating the front and rear of the treadmill 100 with a color typically associated with a warning (such as yellow, orange, or red), the lighting system can warn individuals near the treadmill 100 to be careful when near the treadmill 100.

The lighting system may include a lamp located in the cavity that remains stationary relative to the tread 102. Fig. 9 is a top perspective view of a lamp 900 configured to emit light through a first lens 902. The lamp 900 may include features similar to those of the previously described lamps. The first lens 902 may include a transparent or translucent member configured to receive light from the lamp 900 and emit light through the tread 102 (not shown in fig. 9). The first lens 902 may be made of any plastic (such as acrylic), glass, or any other material configured to refract light emitted by the lamp 900. The first lens 902 may have a curved shape and may extend around a portion of the circumference of the front axle 300, the rear axle 302, the front axle drum 304, or the rear axle drum 306. For example, the first lens 902 shown in fig. 9 comprises a plastic sheet having a curved shape such that the first lens 902 may be attached to the treadmill 100 around a portion of the circumference of the front axle drum 304. The first lens 902 may be located upstream of the front axle 300 or front axle drum 304 with respect to the movement of the tread 102. In this position, the first lens 902 may illuminate the front of the treadmill when the light 900 is activated. The first lens 902 may include ribs 904 extending along the length of the first lens 902 to structurally stiffen the first lens 902.

A second lens (not shown) having similar features to those of the first lens 902 may include a curved shape and may extend around a portion of the circumference of the rear axle 302 or rear axle drum 306 so that the rear of the treadmill 100 may be illuminated. The second lens may be located in a cavity downstream of the rear axle 302 or rear axle drum 306 relative to the movement of the tread 102. A second set of lamps (not shown) having similar features to those of lamp 900 may be attached to the second lens.

The light 900 may be positioned and/or configured in the cavity such that the light 900 shines through the first lens 902 to illuminate a portion of the tread 102. For example, a light may be positioned on an edge of first lens 902 such that light emitted by light 900 is refracted by first lens 902 and transmitted through the spaces between adjacent slats of tread 102. In the non-limiting example shown, the lamp 900 is located on the housing 906. The housing 906 is attached to the edge of the first lens 902 so that the lamp 900 emits light through the first lens 902. In other embodiments, the housing 906 may be attached to any portion of the first lens 902. The housing 906 may include: a bracket configured to attach to the first lens 902; a transparent flexible tube in which the lamp 900 is located; an elongate strip; or any other device configured to attach the lamp 900 to the first lens 902. In other embodiments, the lamp 900 may be directly attached to the first lens 902. In other embodiments, the lamp 900 may not be connected to the first lens 902 and may be positioned near the first lens 902 such that the lamp 900 emits light through the first lens 902. The first lens 902 may include: an aperture 908 to attach the first lens 902 to the frame 202; a lens holder; or any intermediate component or any other component of the treadmill 100.

Fig. 10 is a top perspective view of first lens 902 and third lens 1002 located in cavity 1000. The cavity 1000 may include features similar to those of the previously described cavities. In the non-limiting example shown, the first lens 902 is attached to the lens holder 1004 such that the first lens 902 extends around the front hub 304. A housing 906 is attached to the bottom edge of the first lens 902. Lens holder 1004 is attached to a member of frame 202. The lens holder 1004 may be attached to the first lens 902 and the frame 202 using any attachment means. In the position shown in fig. 10, the first lens 902 may illuminate the front of the treadmill when the light 900 shines through the first lens 902. A second lens (not shown) having similar features as the first lens 902 may be similarly attached to the rear of the treadmill 100 such that the second lens may extend around the rear axle drum 306 and illuminate the rear of the treadmill 100.

Unless otherwise described, third lens 1002 may include features similar to those of first lens 902. The third lens 1002 may extend along the length of the middle portion of the treadmill 100. In other embodiments, the third lens 1002 may extend along any length of the treadmill 100. Third lens 1002 may include flanges 1005 and an arcuate portion 1006 extending between flanges 1005. The flange 1005 may be integral with the arcuate portion 1006 or may be separately connected to the arcuate portion 1006. In other embodiments, the third lens may comprise any other shape or orientation. The flange 1005 may be attached to a top surface of the bearing support 1008. Bearing support 1008 may support bearings for rotating a belt attached to a slat (not shown) forming tread 102. In other embodiments, the third lens 1002 may be attached to any portion of the frame 202 or any other component of the treadmill 100. A lamp 1010 having similar features to those of the lamp 900 may be configured to emit light into the third lens 1002 to illuminate the middle of the treadmill 100. For example, light 1010 may be positioned on an edge of third lens 1002 such that light emitted by light 1010 is refracted by third lens 1002 and emitted through the spaces between adjacent slats of tread 102. In the non-limiting example shown, the lamp 1010 is located on a housing 1012 having similar features to those of the housing 906. A housing 1012 is attached to an edge of the third lens 1002 so that the lamp 1010 emits light through the third lens 1002. In other embodiments, housing 1012 may be attached to any portion of third lens 1002.

In other embodiments, the treadmill 100 may include a lens configured to extend along the length of the treadmill 100 and extend around the front and

rear axes

300, 302. The lights and/or housing may be attached to the lens as described such that the lights illuminate the front, rear, and middle of the treadmill 100.

FIG. 11 is a side view of tread 102 and cavity 1000 with light 1100 in the cavity and held stationary with respect to tread 102. The lamp 1100 may include features similar to those of any of the lamps previously described. Light 1100 may be attached to a cross member 1102, which may or may not be a member of frame 202. Cross member 1102 may be attached to frame 202 at opposite longitudinal ends. In other embodiments, the light 1100 may be attached to any member of the frame 202 or any other component located in the cavity 1000. The lights 1102 are configured to emit light away from the cross members 1102 and through the spaces between adjacent slats. In the non-limiting example shown, the light 1100 is connected to the cross member 1102 within the cavity 1000 such that the light 1100 illuminates the middle of the treadmill 100. In other embodiments, the lights 1100 may be connected to the cross member 1102 such that the lights 1100 also illuminate the front and rear of the treadmill 100. The controller 314 may control the color, brightness, and frequency of illumination of the light 1100 based on the position of the light 1100 relative to the treadmill. For example, the controller 314 may control the lights 1100 located near the front and rear of the treadmill 100 to emit yellow light through the space between adjacent slats. The controller 314 may also control a light 1100 located near the middle of the treadmill 100 to emit green light through the tread 102. The lights 1100 may be positioned such that there is at least one light associated with each space between the slats. Alternatively, the lamps may be spaced in the cavity at intervals not associated with the slat size.

The lighting system may include lights located on the slats forming the tread 102 such that the lights rotate with the tread 102 about the front and

rear axles

300, 302. FIG. 12 is a side view of slat 1200. The slat 1200 may include a tread surface 1202 on which a user exercises. Slat 1200 may also include an underside 1204 that includes any surface of slat 1200 that is not tread surface 1202, including any side surface. One or more lights 1206 may be attached to the underside 1204 of the slats such that the lights 1206 emit light through the spaces between adjacent slats forming the tread 102. The lamp 1206 may include features similar to features of any of the lamps previously described. In the non-limiting example shown, a series of lights 1206 are attached to each of the front and rear surfaces of the underside 1204 of the slat 1200. In other embodiments, the series of lights 1206 may be attached to only one of the front or back surfaces of the underside 1204. Light 1206 may be attached to lower side 1204 of slat 1200 using a housing as previously described. For example, a light cord or light bar may be attached to the front edge of the underside of each slat 1200.

Lights 1206 attached to each slat 1200 may be controlled by a controller. The controller may include controller 314 or any other controller. The controller 314 may be configured to control the activation, deactivation, color, brightness, and/or frequency of illumination of the light 1206. Alternatively, each slat 1200 may include a light controller attached to the underside 1204 of slat 1200. Each lamp controller may be configured to control the lamps 1206 of each respective slat in the same manner as the controller 314. Each lamp controller may be in communication with the controller 314.

The controller 314 may be configured to control activation, deactivation, color, brightness, and/or frequency of illumination of lights 1206 attached to the slats 1200 in response to determining the position of the slats 1200 relative to the treadmill. For example, in response to determining that the slat 1200 is located in the front or rear of the treadmill 100, the controller 314 may control the light 1206 to emit light in a first color (e.g., yellow). In response to determining that the slat 1200 is located in the center of the treadmill 100, the controller 314 may also control the light 1206 to emit light in a second color (e.g., green).

To power lights attached to slat 1200, slat 1200 may include a contact 1208 attached to underside 1204 and in electrical communication with light 1206. The contact 1208 may be attached to the underside 1204 within a recess defined by the underside 1204. The contacts 1208 may receive power from a power rail (described further with respect to fig. 13) that extends along the length of the treadmill 100 and is located in the cavity 1000. The lamp 1206 may be supplied with power received by the contactor 1208. As the slat 1200 rotates about the front and rear axles, the contactor 1208 receives power from the power rail that remains stationary relative to the tread 102 in response to contacting the power rail. The contactors 1208 may include motor brushes (e.g., carbon brushes) or any other components configured to receive power from a power rail and supply power to the lamps 1206. The strip 1200 may include a plurality of contacts 1208, including a contact for conducting positive charge and a contact for conducting negative charge. The slats 1200 may include contacts 1208 located at opposite longitudinal ends of the slats 1200.

Fig. 13 is a top perspective view of power rail 1300. The power rail 1300 may include an elongated member configured to supply power to the contacts 1208 in response to contacting the contacts 1208 as a slat (e.g., the slat 1200) rotates about the front and rear axes. The power rail 1300 may receive power from the battery 310, a power cord, an electric motor, or any other power source. The power rail 1300 may be shaped to receive the contacts 1208 as the contacts 1208 and the slats 1200 rotate about the front and rear axes. For example, the power rail 1300 may include one or more channels configured to receive the contactors 1208.

The power rail 1300 may include one or more strips 1302 of conductive material (e.g., copper) attached to an insulator member 1304. The strip of conductive material 1302 supplies power to the contacts 1208 while the strip of conductive material 1302 is in contact with the contacts 1208. The insulator member 1304 may be made of any insulating material (e.g., rubber or plastic) and may electrically insulate the strip of conductive material 1302 from other components of the treadmill 100. The insulator member 1304 can include a wall 1306 configured to electrically insulate the strips of conductive material 1302 from one another (e.g., to separate the positive contact and the negative ground). Each of the strips of conductive material 1302 can receive one of the contacts 1208. For example, one strip of conductive material 1302 can receive a first contact while another strip of conductive material 1302 can receive a second contact. The insulator member 1304 may be connected to the bearing support 1008, any portion of the frame 202, or any other component of the treadmill 100 such that the contacts 1208 may contact the strip of conductive material 1302 as the slat 1200 rotates about the front and rear axes.

As slats 1200 rotate about the front and rear axes, a contactor 1208 attached to an underside 1204 of a slat 1200 contacts power rail 1300 and supplies power to lights 1206 attached to the respective slats 1200. When energized, the lights 1206 shine through the spaces between adjacent slats to illuminate portions of the treadmill 100. In some embodiments, each slat 1200 includes a contact 1208. The contact 1208 of each slat may be configured to supply power to the light 1206 connected to the underside of each respective slat 1200 in response to contacting the power rail 1300. In such embodiments, when the slats 1200 are rotated such that the contactors 1208 no longer contact the power rails 1300, the lights 1206 attached to the slats 1200 are not powered and do not illuminate. Thus, the power rail 1300 may be located within the cavity 1000 where illumination of the treadmill 100 is desired. For example, power rail 1300 may be positioned near the top of cavity 1000 such that when slats 1200 are rotated about the front and rear axes, power rail 1300 powers lights 1206 attached to slats 1200 currently located in the middle of treadmill 100. In another example, portions of the power rail 1300 may extend around the front and rear axles of the treadmill 100. In this configuration, the power rail 1300 may provide power to lights 1206 attached to the slats 1200 to illuminate the front, rear, and/or middle of the treadmill 100 as the slats 1200 rotate about the front and rear axes.

In other embodiments, only some of the slats forming the tread 102 may include the contacts 1208. In such embodiments, the strip including the contact 1208 may be electrically connected to the strip that does not include the contact 1208 using one or more conductors 1210 (shown in fig. 12). The conductor 1210 may be in electrical communication with the contactor 1208. The conductors 1210 may include a jumper or any other electrical connector. The conductor 1210 supplies power from the contact 1208 in contact with the power rail 1300 to the lamp 1206 attached to the strip 1200 that does not include the contact 1208. In other words, a light 1206 connected to a strip other than the strip including the contact 1208 may receive power from the conductor 1210 in response to the contact 1208 contacting the power rail 1300. In this configuration, the number of slats 1200 that include the contacts 1208 may be reduced. For example, if the tread 102 includes 64 slats connected in series, one of each 32 slats in the series may include a contactor 1208 such that one contactor 1210 is always in contact with the power rail 1300 as the tread 102 rotates about the front and rear axles. In this example, a light 1206 attached to 62 slats that do not include a contactor 1208 may be powered by a conductor 1210. The contacts 1208 and conductors 1210 may provide power to the lights 1206 attached to each slat 1200 to illuminate the front, rear, and middle of the treadmill 100.

Fig. 14 is a partial rear view of a slat 1200 including a contactor 1208 that contacts a power rail 1300, according to one embodiment. In the non-limiting example shown, two contacts 1208 are attached to the underside 1204 of the slat 1200. One end of each contact 1208 contacts the strip 1302 of conductive material of the power rail 1300. The opposite end of each contact 1208 includes an actuator 1400 (e.g., a spring) configured to maintain contact between the contact 1208 and the strip of conductive material 1302. The strip 1302 of conductive material is connected to an insulator member 1304. The walls 1306 separate the strips 1302 of conductive material from each other and insulate them. Insulator member 1304 is connected to bearing support 1402. Bearing support 1402 may support bearings (not shown) configured to support belt 1404 for rotation about the front and rear axes. One end of the slat 1200 is connected to a belt 1404. Another belt (not shown) may be connected to slat 1200 at an opposite end of slat 1200. Bearing support 1402 is connected to frame 202. A conductor 1210 is connected to the underside 1204 of the strip 1200 in the recess 1406.

Treadmill 100 may include a combination of fixed lighting in cavity 1000 and lights 1206 attached to underside 1204 of slat 1200. As previously described, the lighting system may include a first set of lights configured to illuminate the front of the treadmill 100, a second set of lights configured to illuminate the rear of the treadmill 100, and a third set of lights configured to illuminate the middle of the treadmill 100. Any of the first, second, or third sets of lights may comprise any combination of the embodiments of the lighting system described with respect to fig. 9-14. For example, the first set of lights may include a first lens 902 extending around the front axle drum 304 and a light 900 attached to the lens 902, as previously described. For example, the second set of lights may include a second lens extending around the rear hub 306 and lights attached to the second lens, as previously described. The third set of lights may include light 1206 attached to slat 1200 forming tread 102. The power rails 1300 may extend along the length of the middle portion of the treadmill 100 such that the lights 1206 are powered to illuminate only when they rotate through the middle portion of the treadmill 100 along the top of the cavity 1000. In this configuration, no power is supplied to the lights 1206 as the slats 1200 are rotated through the front and rear of the treadmill. In other embodiments, power rail 1300 may also be positioned such that light 1206 is powered only when slat 1200 is rotated through the front and/or rear of the treadmill. Alternatively, the light 1206 may be controlled by the controller 314 to illuminate in response to the controller 314 determining that the light 1206 is located in the middle of the treadmill 100. In another example, the third set of lights may include lights 1100 attached to cross member 1102 within cavity 1000 such that lights 1100 emit light through the space between adjacent slats to illuminate the middle of treadmill 100.

The lighting systems described herein may be used in many different ways, some of which are described herein. For example, the lights may be turned on when the proximity sensors detect that a person is approaching the treadmill 100. The lights may be controlled to flash as a reminder to the approaching person.
