Abstract:
A foldable bed includes a first frame and a second frame. The first frame has a first board put thereon. A first connector is connected to the front end of the first frame and has a first pin hole and a first aperture which is located below the first pin hole. The second frame has a second board put thereon. A second connector is connected to the rear end of the second frame and has a second pin hole and a second aperture which is located below the first pin hole. A pivot extends through the first and second apertures to pivotably connect the first frame to the second frame. When the first and second frames are extended. A pin extends through the first and second pin holes.
Abstract:
An adjustment device includes a casing to which a movable member and two positioning members are movably connected. Two links are connected between the movable member and the positioning members. Each positioning member has a magnetic member connected thereto and the flywheel has a magnetic operation face. When the movable member moves from a second position to a first position, the links drive the positioning members and the magnetic members from a close-to-center position to an off-center position, and the flywheel cuts the magnetic field of the magnetic members to generate a first resistance to the driving device and the flywheel. When the movable member moves from the first position to the second position, the positioning members and the magnetic members move from the off-center position to the close-to-center position to generate a second resistance that is different from the first resistance.
Abstract:
An adjustable weight assembly includes a weight device and an adjustment device. The weight device includes a rail, a movable member and multiple weights. The movable member is connected to a rod and receives a force applied by a force applying unit so as to move along the rail. The rod has multiple through holes and each weight has a latitude hole and a longitudinal hole. Each latitude hole has a pin extending therethrough and the rod extends through the longitudinal holes. The adjustable device includes a driving unit, a movable part and multiple pivotal members. The driving unit drives the movable part and each weight is pivotably connected to one of the pivotal members. When the movable part moves along the rail, the pivotal member is pivoted to decide the engagement between the pin and the through hole so that the user can adjust the number of the weights.
Abstract:
A hub motor for electric vehicles and includes a rim, connecting members, a motor housing, a gear ring, a coil unit, a shaft, a tube, a magnet unit, a sun gear, a planet gear frame and multiple planet gears. The gear ring and the coil unit are fixed in the motor housing and two bearings are located between the shaft and the motor housing so that the motor housing is rotatable relative to the shaft. The tube has the magnet unit and the sun gear, and the planet gear frame is fixed to the shaft and the planet gears are connected to the planet gear frame. The planet gears are engaged with the gear ring and the sun gear.
Abstract:
The present invention relates to a positioning switch mechanism for foldable assembly of bicycles, comprising a positioning switch assembly, a first rotary member and a second rotary member which are able to revolve against each other along a rotation axis. The positioning switch assembly has a press button assembly set in the first rotary member with a spring and a pin set in the second rotary member with a spring as well. When the first rotary member revolves close to overlap against the second rotary member, the first rotary member pushes the pin to be drowned back into the second rotary member. The first rotary member continues to revolve against the second rotary member till they are completely overlapped. The pin limits itself in the first rotary member so as to fix with the second rotary member. When the press button assembly takes pressure from the user, it pushes the limit portion to be drowned back into the second rotary member so that the positioning switch assembly is in an unlocked state and the first rotary member is capable of revolving against the second rotary member.
Abstract:
A treadmill includes a base with two side rails, a frame with two side rods and an endless running belt, two first links, two second links, two third links, a fixing rod which is fixed in-between the two first links with a connection and an actuator is composed of a motor and a motor driven moving part which is pivotally connected to the connection of the fixing rod. Each group of the first links, the second links, the third links and the side rail is structured as a four-bar-link mechanism, which is working to bring up or down the first end of the frame when the actuator is driving the moving part, incline angle of the frame is changing, the purpose of adjusting the inclination of the frame and even folding the frame is simply and efficiently achieved.
Abstract:
This invention relates to a wireless ear-clips heart rate monitor comprising a sensor unit of ear-clips type that detects a user's heart rate, a signal-processing unit that receives and processes the signal generated from the sensor unit, and a wireless signal-transmitting unit that receives the signals from the signal-processing unit and then transmits the signals out. The sensor unit detects frequency of change of blood density to derive heart rate, with the features of precision and efficiency on the detection of heart rate, cooperating with the technique of wireless transmission, the purpose of promoting accuracy of detection and improving convenience of using is attained.
Abstract:
A treadmill includes a base and a frame has a first end thereof pivotably connected to the base and an endless belt is connected to the frame. A guide rod has its axis extending lengthwise of the frame and a fist end of the guide rod is fixed to the base. A second end of the guide rod connected to the base. A sleeve extends through a through hole in a transverse bar of the base 10 and the guide rod is received in the sleeve which is able to move along the guide rod back and forth. A supporting rod has a first end thereof pivotably connected to a pivotal portion on the sleeve and a second end of the supporting rod is pivotably connected to a first pivotal portion on the frame. A securing device is connected to the sleeve so as to secure movement of the sleeve relative to the guide rod so that the frame can be kept at upright position.
