Abstract:
The present invention relates to a human-propellable vehicle comprising a chassis and a footplate for receiving a rider's feet. The footplate is movably mounted to the chassis so that at least part of the footplate can be deflected up towards the rider in the event of a collision between the underside of the footplate and an object or terrain passing under the chassis.
Abstract:
A bicycle (1000) includes a frame (1002), a suspension assembly (100) and a steering assembly (1018). The frame includes a head tube (1003) that rotatably receives a front fork assembly (1004). A steerer tube (1008) extends axially away from a fork crown (1010) of the front fork assembly. The suspension assembly includes an upper tubular support (102) longitudinally slidable relative to a lower tubular support (104). The upper and lower supports receive a first positive biasing means (138) and a first negative biasing means (140). The lower and upper supports are respectively connected to the steerer tube and a stem (1020) of the steering assembly such that the upper support slides longitudinally relative to the lower support adjacent the stem and above the fork crown.
Abstract:
A suspension system (12) disposed in a bicycle fork (10). The suspension system includes inner and outer tubes (14,16), first and second bushings (20,22), a steering mechanism (24) and a shock-absorbing mechanism (18). The first and second bushings (20,22) are disposed between the inner and outer tubes to facilitate the sliding of the inner tube (14) within the outer tube (16). The steering mechanism (24) prevents relative rotation between the inner and outer tubes (14,16) and is disposed between the first and second bushings (20,22). With this configuration, the ratio of the bushing length to the inner tube diameter is greater than 4, resulting in the suspension fork handling most lateral loads without binding.
Abstract:
PROBLEM TO BE SOLVED: To improve the responsiveness of a damper of a suspension mechanism while maintaining a compact dimension in a longitudinal direction of a vehicle in a vehicle which supports a front wheel by a swing arm system.SOLUTION: A front wheel support structure of a vehicle includes: a front arm (10) which supports a front axle (6), extends rearward from a front axle support portion, and may swing in a vertical direction; and a suspension mechanism (12) which elastically inhibits vertical swing of the front arm. The suspension mechanism (12) includes: a damper member (33) which is arranged in a vertical space between a head tube (1) of a vehicle body frame (F) and the front arm (10) along a crosswise direction; and a bell crank member (32) which connects the front arm (10) with the damper member (33) so as to convert the vertical swing of the front arm (10) into crosswise expansion and contraction of the damper member (33).

Abstract:
A vehicle height adjustment apparatus according to one embodiment include a spring (500), a spring-length changing unit (250), a first valve (301), a control valve (305) and a second valve (302). The spring-length changing unit (250) changes a length of the spring (500) in accordance with an amount of oil in a jack chamber (60) that accommodates the oil. The first valve (301) opens and closes a first communication path in which the oil supplied from a pump (600) is oriented toward a reservoir chamber (40) that stores the oil. The control valve (305) opens and closes a discharge flow path oriented toward the reservoir chamber (40) from a chamber (B1) that accommodates the oil to close the first valve (301). The second valve (302) opens and closes a second communication path in which the oil supplied from the pump (600) is oriented toward the jack chamber (60) when the first valve (301) is closed.
Abstract:
A flow path control device according to one embodiment includes a first valve (304) which transitions between a closed state where a first flow path is closed and an open state where the first flow path is open by moving toward an space (S1) from the closed state. The first valve (304) is formed with an axial through-hole (393) that communicates with the first flow path and the space (S1). A pressure-receiving area (A1) of the first valve (304) against a jack chamber (51) is smaller than that against the space (S1). Further, a second valve (303) is provided in the space (S1) on a second flow path so as to transition between a first state where a radial through-hole (393) is closed and an inflow path oriented toward the space (S1) from the jack chamber (51) is open and a second state where it is closed and the radial through-hole (393) is open.
