摘要:
A bicycle rack includes a fist rod (10) and a second rod (11). A first plate (20) and a second plate (21) are pivotably connected to each other and connected between the first and second rods (10,11). A clamping unit (40) is connected to the two respective lower ends of the first and second rods (10,11) and clamps the hitch ball (70). Two support arms (50) are respectively connected to the first and second rods (10,11). An operation unit (30) is connected to the first and second plates (20,21) and controls the pivotal action of the first and second plates (20,21). Two folding units (60) are respectively connected to the first and second rods (10,11) and the two support arms (50) are fixed to the two mounting members (61). The mounting members (61) together with the support arms (50) are able to be folded toward the first and second rods (10,11) by loosening the two folding units (60).
摘要:
A bolt assembly includes a head (20) having a lock (21) connected thereto which includes an eccentric rod (211) with a curved outer periphery (2111) and a flat surface (2112). A bead (212) is retractably connected to an outer periphery of the curved outer periphery (2111). A shank (30) has teeth (33) in an outer periphery thereof and has an end plate (31) which has recesses (310) such that the curved outer periphery (2111) of the eccentric rod (211) can be selectively and removably engaged with one of the recesses (310) by using a key to operate the lock (21). A cover (40) is connected to an underside of the head (20). The shank (30) is co-rotated with the head (20) when the curved outer periphery (2111) of the eccentric rod (211) is engaged with one of the recesses (310). When the curved outer periphery (2111) of the eccentric rod (211) is removed from the recesses (310), the head (20) is independently rotated relative to the shank (30) so that the bolt assembly cannot be unscrewed.
摘要:
A replaceable top tube includes an outer tube (10) and an inner tube (100) retractably received therein. Two sleeves (20,20') are respectively connected to the outer tube (10) and the inner tube (100), and two locking plates (40) are respectively connected to the two sleeves. Two hooks (30) are respectively connected to the inner tube (100) and the outer tube (10) so that when the sleeves are pulled, the locking plates (40) are moved away from the hooks (30) so as to hook the seat post and the handlebar stem of a bicycle. Each of the two sleeves are positioned by a resilient member (16).
摘要:
A bicycle rack assembly includes a base plate (10) on the vehicle and has a first connection tube (11) to which a second connection tube (21) extending from a vertical portion of a frame (20) is connected. A slot (111) is defined in a wall of the first connection tube and a plurality of positioning holes (211) are defined through a wall of the second connection tube so that a first bolt (22) extends through one of the positioning holes and is engaged with the slot. Two support plates (25) are connected to a horizontal portion of the frame and each support plate has a first groove (251). A cap (26) has two second grooves (261) defined in an underside thereof and is connected to the horizontal portion with the two second grooves located to match with the first grooves so as to clamp two respective top tubes of bicycles in the grooves. The frame (20) can be adjusted an angle relative to the base plate (10).
摘要:
A clamp device includes a connection member (30) which has two side plates (32) extending from a side thereof and a bicycle rack assembly (B) is connected to a top of the connection member. A first fixing member and a second fixing member are respectively fixedly and pivotably connected between the two side plates so that a connection sphere extending from a rear end of a vehicle is clamped between the two fixing members. A pressing bar (60) extends through the two side plates and has a plane surface (621). A pressing plate (50) is inserted between a pressing bar (60) and the second fixing member and pressed by the plane surface (621) of the pressing bar (60). A lower section of the pressing plate extends from the insertion at an angle and includes a notch (51) which presses on a bar (11) extending from the connection sphere. The lower section also presses the second fixing member toward the connection sphere.
摘要:
A bicycle rack includes a main frame (20) connected to an upright post (100) and the ball (12) on the rod (11) connected to the vehicle is located between two side plates (22) and clamped by two clamping members (30,31). A pressing plate (50) has an upright plate (51) located between the two side plates (22) and a horizontal plate (52) which is connected to a holding member (60). A positioning bar (40) has a cam section (41) for pressing the pressing plate (50) to push one of the two clamping members (30,31) to clamp the ball (12). A U-shaped retaining member (70) is engaged with the rod (11) and is connected to the holding member (60) by using a U-shaped retaining piece (70). The ball (12) and the rod (11) are both secured so as to prevent the bicycle rack from shaking.
