This invention generally relates to counters and in particular to counters for use with dispensers and to dispensers comprising said counters. More particularly the present invention relates to counters for use with metered-dose dispensers, such as metered-dose inhalers (MDIs). In particular, the present invention provides a counter comprising: a first ring member having a first indicia and being rotatable in increments about an axis, the first indicia indicating a count; a limiting member comprising a limiting mechanism, wherein the limiting mechanism comprises an engaging portion arranged to act radially with respect to the first ring member to contact the first ring member to limit free rotation of the first ring member relative to the limiting member about the axis.

A torque transfer control mechanism that suppresses output-side displacement, and including a rotation control unit that maintains a locked state when an input torque rotating a transfer mechanism is not applied, and releases the locked state when the transfer mechanism rotates. The rotation control unit includes an internal gear and lock plates that include outer teeth that can engage with inner teeth of the internal gear. When an input torque is not applied, the inner teeth of the internal gear engage with the outer teeth of the lock plates, and when the transfer mechanism is rotated, engagement between the inner teeth and the outer teeth is released. Thus, even when torque is applied from the output unit side, engagement between the inner teeth and the outer teeth is not released by the torque.

A solution to reduce the ratcheting sound that occurs at the start of braking when an operation pedal is operated by foot. Because a mounting seat as a flat part and base plate are provided between a ratchet member and support axial center S of an operation pedal, there is a possibility that the ratchet member's vibration will propagate to the adjacent mounting seat and base plate, amplifying the ratchet sound. However, the adjacent mounting seat and base plate are provided with beads, having cross-sections that bend convexly in a direction substantially orthogonal to the vibration waveform of the ratchet sound produced by a pole coming into contact with serrations when the mounting seat and base plate maintain a flat plate shape; i.e., in a circumferential direction about support axial center S. Therefore, rigidity against the vibration is increased, propagation of vibration is minimized, and ratchet sound is effectively reduced.

A knob device for vehicle includes a knob unit and a locking unit. The knob unit includes a rotating cover with an open end, a rotary shaft mounted to the open end, and a motor fixed to the rotating cover for driving the rotating cover to vibrate. The locking unit includes a rotary wheel which includes a main body fixed to the rotary shaft and latching teeth formed at a periphery of the main body and distributed in a ring around a central axis of the rotary wheel, a gap being defined between two neighboring teeth, an iron core configured to be inserted into the gap to limit rotation of the rotary wheel, and a solenoid connected to the iron core for driving the iron core to move. The knob device can realize locking of the rotary wheel clockwise and counter-clockwise, meeting requirement of diverse use.

A riding mower includes a seat, a main rack configured to bear the seat, a mowing element, a walking assembly for enabling the riding mower to walk across a lawn, and an operation assembly configured to be operated by the user so that the riding mower is controlled to walk and output power. The riding mower further includes a parking system, a linkage mechanism and a gearbox. The parking system is configured to switch the riding mower between a parking state and a non-parking state. The linkage mechanism is connected to the parking system. The gearbox is connected to the linkage mechanism. The parking system controls, through the linkage mechanism, the gearbox to implement braking.

A portable lamp comprises a central body, a boom arm, flat tripod stand, and a light unit. The central body is extendable along its vertical axis to a predetermined length. The boom arm is of adjustable length and is rotatably fixed to the upper end of the central body with a positively locking elbow joint, including a ratchet and pawl. The lower end of the central body is fixed with a foldable locking flat tripod stand adapted to hold and provide mobility to the portable lamp. Flat tripod stand includes a spring-biased latch and detents that hold legs in a folded or a down position. The central body, the boom arm, the tripod stand and the light unit are configured to provide up to twelve degrees of freedom jointly.
