Abstract
Abstract A saddle rod for bicycles and like vehicles which is in the form of a tube that is engaged and secured within a mating tube of a cycle frame. A head is affixed to the upper end of the tube and a carriage formed of two clamping flanges for the wires of the saddle frame, is connected to the head by a single screw for assembling the elements. Hence, the saddle relative to the saddle rod is secured after lengthwise and angular adjustment.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
A saddle rod for bicycles and the like, comprising: a saddle tube (1) having a spherical head (1b); a head carriage unit having a lower element (3) forming a spherical cap (3b) which rests upon said spherical head, said head carriage unit encases the wires of a saddle frame; a screw passing through said spherical head secures said head carriage unit to said saddle tube; and said spherical head is provided with a vertical bore (1c) for said screw, having an hourglass shape with an approximate circular section at the center of said bore, the diameter of said circular section is slightly larger than the diameter of said screw passing therethrough, wherein said vertical bore is further provided with egg-shaped and flared sections at the periphery of the sphere in a lengthwise direction so that said screw can be angularly shifted and thereby said head carriage unit in the lengthwise direction only.
Claim 2
Dependent Claim
152 words
A saddle rod for bicycles and the like, comprising: a saddle tube (1) having a spherical head (1b); a head carriage unit having a lower element (3) forming a spherical cap (3b) which rests upon said spherical head, said head carriage unit encases the wires of a saddle frame; a screw passing through said spherical head secures said head carriage unit to said saddle tube; and said spherical head is provided with a vertical bore (1c) for said screw, having an hourglass shape with an approximate circular section at the center of said bore, the diameter of said circular section is slightly larger than the diameter of said screw passing therethrough, wherein said vertical bore is further provided with egg-shaped and flared sections at the periphery of the sphere in a lengthwise direction so that said screw can be angularly shifted and thereby said head carriage unit in the lengthwise direction only.
Claim 3
Dependent Claim
121 words
A saddle rod as defined by claim 1 wherein the lower element of said head carriage unit comprises a convex central portion defining a hole for the passage of said screw and having a lower face defining said spherical cap (3b), the lower element is also provided with lateral sides having recesses (3e) for receiving the wires of a saddle frame; and said head carriage unit further comprises an upper element having a means into which said screw is threaded, the upper portion is provided with lateral sides having curved faces (2c) for encasing with said recess the wires of a saddle frame; and a lower concave central portion (2b) which mates with the convex central portion of said lower element.
Claim 4
Dependent Claim
54 words
A saddle rod as defined by claim 2 further comprising a stop means which prevents said carriage unit from swinging relative to said spherical head in a crosswise direction, said stop means is provided at two opposed locations on said spherical head and beneath the lower element on either side of the spherical cap.
Claim 5
Dependent Claim
56 words
A saddle rod as defined by claim 3 wherein said stop means comprises studs (6) projecting from said sphere and the lower element is provided with recessed imprints (3f) which cover the studs, the recessed imprints are separated from the studs when said spherical cap is in contact with said spherical head by an operational clearance.
Claim 6
Dependent Claim
61 words
A saddle rod as defined by claim 3 wherein said stop means comprises opposed parallel flat portions (1d) on said spherical head and the lower element is provided with bosses (3g) along the edge of said spherical cap, the bosses are separated from the flat portions when said spherical cap is in contact with said spherical head by an operational clearance.
Claim 7
Dependent Claim
69 words
A saddle rod as defined by claim 3 further comprising a washer (5) having a spherical surface which rests on said spherical head, said screw is provided with a screw head, and the washer is fitted onto said screw, so that the washer is located between the screw head and the spherical head, the spherical surface is provided with reinforcement roughenings which clamp the spherical head to the screw.
