A two-wheeled vehicle includes a frame having a front frame portion, a mid-frame portion, and a rear frame portion. The mid-frame portion is coupled to the rear frame portion and the front frame portion. The vehicle further includes a plurality of ground-engaging members for supporting the frame. The front frame portion is removably coupled to the mid-frame portion with a plurality of frame members extending between the front frame portion and the mid-frame portion.

A foldable bicycle comprises a front frame (1), a rear frame (21), and a seat tube (20). The front frame (1) and the rear frame (21) are foldable with respect to each other. In a first aspect, a single release clamp (12) releases the front frame from the rear frame in a single operation. This occurs by having the seat tube (20) slotted at the top (11). In a second aspect, the crank housing (34) is positioned in axial alignment with the seat tube (20) and one point (14) of folding occurs below the crank housing. This aspect pertains to both a men's and a women's frame.

A bicycle frame, having the usual front fork, backfork (14), steering head sleeve (1) and pedal shaft sleeve (7) has an oblique tube (2), extending towards the steering head sleeve (1), is pivotably connected to the backfork (14) and is substantially in alignment with the back fork, a bar (6) extends from the pivot point towards a saddle support means (14), and a bar (8) extends towards the pedal shaft sleeve (7), said bars being likewise substantially mutually in alignment, the free ends of the bars (6,8) being connected to the free end of the back fork (14) and to the steering head sleeve (1) by tensioning wires (17 to 24). This frame is lighter in weight and yet more rigid due to the tensioning wires (17-24). It is easily demountable and packable into a box when the pivot connections (9-12,15) and the tensioning wire connections are insert connections (25-28).

The invention concerns the folding frame of a two-wheel vehicle. The two-wheel vehicle frame has front section of the frame (1) and rear section of the frame (2) connected by a dual-axis swivel (3) having two axes that are fixed to each other: the vertical axis of rotation (4), which is in the same plane as the axis of rotation of the front wheel fork (12) and, at the same tame, is within the symmetry plane of the rear section of the frame (2) or the symmetry plane of the rear wheel or rear tyre, and the horizontal axis of rotation (5), which is perpendicular to the symmetry plane of the rear section of the frame (2) or the symmetry plane of the rear wheel or rear tyre. The two-wheel vehicle frame according to the invention allows the compact folding of a vehicle.

The invention is a bicycle frame (11) having an integrated bicycle locking mechanism (27). Roughly mid-length of a tube of the bicycle frame is removed in order to accommodate the locking mechanism (27). Secured within one of the exposed ends of the frame is a flexible wire (20) that can emerge and lock itself to a locking receptacle (28) located on the other open end of the frame (13). Located on the exposed end of the flexible linkage is the locking mechanism (27). The invention is designed so as to enable the flexible wire (20) to wrap around a stationary object, such as a pole or bicycle stand. Alternatively, the flexible wire can wrap around the rear wheel of the bicycle so as to prevent the bicycle from being used.
摘要:
A vehicle frame (1) comprising a plurality of interconnectable frame portions (1 to 31b), wherein one of the vehicle frame portions (2) is assembled in a first location with vehicle components to form an intermediate frame component which is assembled to the remainder of said frame portions at a second location different from the first location. The frame (1) may be split into portions at a point allowing the front frame portion (50) to bear the load of the rider. The present invention minimizes assembly operations at the vehicle assembly stage thereby reducing the vehicle assembly line space, material handling capacity and time required for vehicle assembly. The frame portions (1 to 31b) of such a vehicle frame (1) provide a frame assembly for a vehicle which facilitates different surface treatments on the frame assembly at different locations in a, straightforward cost-effective manner.
