Embodiments of the present invention relate to an improved stimulation device. Embodiments of the improved stimulation device includes a cup and a driver. The cup has a cavity surrounded by a rim. The driver comprises a plate disposed on an underside of the cup, a cam disposed adjacent to the plate, and a motor mechanically coupled to the cam. The driver comprises a cam pin affixed to the cam, and a bearing rotatably disposed on the cam pin. The bearing is mechanically coupled to a lifter. The lifter is mechanically coupled to a linear bearing, enabling a smooth reciprocating back-and-forth motion from the rotation of the motor. A top of the cup swells and unswells during an operation cycle of the driver.

A massage chair includes a back massage system and a thigh massage system with a roller mechanism configured to move a roller in a three dimensional orbital motion. The roller mechanism is driven by a single motor that can change the direction in operation. Also included is a roller motion drive element within the roller mechanism. A shaft is configured to pass through the roller motion drive element in an offset non-perpendicular angle relative to the end face thereby forming an angle between the shaft and the end face that is less than 85 degrees. The offset causes the orbital motion of the roller when rotated. The electronics of the massage chair facilitate facial recognition and a medical assessment device to detect bodily characteristics. The backrest of the massage chair can elongate to stretch the user. A plurality of airbags are also available for the twisting of the user.

A sex toy with universal connecting structure may include an outer cup body, a sperm collection cup sleeve, an inner cup body, a guide part, a power part, an eccentric wheel transmission assembly and an electric control part, wherein the inner cup body is slidably connected the inside of outer cup body through the guide part, the sperm collection cup sleeve is positioned between the outer cup body and the inner cup body, the cup mouth of the sperm collection cup sleeve is hermetically connected with that of the outer cup body, and the outer cup bottom of the sperm collection cup sleeve is connected with the inner cup bottom of the inner cup body. Since the universal ball head piece matches the universal ball head hole, the inner cup body can rotate along the universal ball head hole while reciprocating along the guide part.

A portable and kinetic motion resistance upper body invention that can be used for a variety of exercises. This invention combines dial tension adjustment clutch sheaves, a variable linear tract bearing and a one piece resistance shock-cord, together these core components achieve a unique minimal impact work-out. The multi-motion and changeable adjustments for this invention, result in a wide variety of muscular stimulation and therapeutic exercises that are non-existent in the fitness and health industry. The outcome of the mechanism can be customized for a particular sport requirement or physio and other therapeutic restorations, or even for case specific industrial and robotic counter-balancing controls. This invention is can also be used as a lift-assist device.

A massage gun includes a triangular handle chamber, a head chamber, and a ball-shaped components chamber formed between the handle and the head chamber; three rechargeable batteries in three parts of the handle chamber respectively; an electric motor in the components chamber; a cam on a motor shaft of the motor and including a main body and an eccentric, cylindrical rod; a linkage in the components chamber and including first and second holes; a first bearing on the cylindrical rod and inserted in the second hole; a second bearing in the first hole; a bearing seat in a joining portion of the components chamber and the head chamber; a bearing sleeve in the head chamber; a reciprocating sleeve engaged with the second bearing and put on the bearing sleeve; and a controller in the components chamber and electrically connected to the motor, the rechargeable batteries, and an on/off switch.

Provided is a massage module and a massage device including same. The massage module may include: a procedure member including an upper finger member and a lower finger member cooperating with the upper finger member; and a cam driving part connected to the upper finger member so as to move the upper finger member in the vertical direction, so that the upper finger member and the lower finger member are away from or close to each other.

A suspension system (2) for assisting a user (4) to navigate a staircase (6), the suspension system comprising: a beam (8) positioned above the staircase (6); a carriage (18) displaceable along said beam (8) between a first position at the bottom of the staircase (6) and a second position at the top of the staircase (6); a harness (14) securable to the user (4), said harness (14) being operably connectable to said carriage (18) such that said carriage (18) follows the user (4) as the user (4) navigates the staircase (6); and a brake (42) operably connected to said carriage (18) for braking said carriage; wherein if the user (4) falls while navigating the staircase (6), said brake (42) stops said carriage (18) in place and the user (4) is suspended above the staircase.
