Abstract

In a preferred embodiment, a shock-absorbing bicycle seat mount, including a post fixedly attached to a bicycle seat at a proximal end of the post, a distal end of the post being inserted into a bicycle seat tube for axial movement therein; biasing apparatus disposed within the seat tube to support the post; an axial movable platform disposed within the seat tube to support the biasing apparatus and the post; biasing apparatus external of the seat tube disposed to connect the support platform to an upper portion of the seat tube; apparatus to prevent rotational movement of the post within the seat tube; and means to manually fix a minimum height of the post and attached saddle with dis-engagement of the shock-absorbing apparatus at that point.

Claims

1. A bicycle seat mount comprising:

(a) a post fixedly attached to a bicycle seat at a proximal end of said post, a distal end of said post being inserted into a bicycle seat tube for axial movement therein;

(b) first biasing means disposed within said seat tube to support said post and provide a cushioning action for said post and said bicycle seat by compression of said biasing means; and

(c) second biasing means having first and second ends, with said first end operatively fixedly attached to the bicycle seat tube, and having said second end attached to an end of said first biasing means to provide a cushioning action for said post and said bicycle seat by extension of said second biasing means.

2. A bicycle seat mount system according to claim 1, wherein said seat tube comprises:

(a) diametrically opposite openings in it'"'"'s lower portion for protrusion of extended ends beyond said seat tube'"'"'s outer wall, of an axial moveable, seat post supportive, platform disposed within the seat tube; and

(b) a notch opening in the perimeter of an upper portion of the seat tube into which an extension of an element for restriction of rotational motion of said seat post may be inserted.

3. A bicycle seat mount system according to claim 1, wherein said seat post has a lengthwise slot defined in a surface thereof for a fixed complementary shape key protrusion therein such that said slot and said protrusion slidingly engage each other and prevent relative rotation between the seat post and the seat tube;

a plurality of holes defined in an inner surface of the slot;

a collar disposed around an outer periphery of the seat post and dimensioned so as to rest on an upper end of the seat tube or any insert flange top surface; and

a transverse member inserted through said collar and into one of said holes to fix a minimum height of the bicycle seat post.

4. A bicycle seat mount comprising:

(a) a post fixedly attached to a bicycle seat at a proximal end of said post, a distal end of said post being inserted into a bicycle seat tube for axial movement therein; and

(b) biasing means disposed within said bicycle seat tube to support said post and provide a cushioning action for the post and said bicycle seat by compression of said biasing means; and

(c) a platform disposed within the bicycle seat tube for support of the post and said biasing means; and

(d) means mounted between said platform and the bicycle seat tube to redirect the downward force loading from the post on the platform to an upper portion of the bicycle seat.

5. A bicycle seat mount system according to claim 4, wherein said seat tube has diametrically opposite openings in it'"'"'s lower portion for protrusion of extended ends of said platform beyond said seat tube'"'"'s outer wall.

6. A bicycle seat mount comprising:

(a) a post fixedly attached to a bicycle seat at a proximal end of said post, a distal end of said post being inserted into a bicycle seat tube for axial movement, therein; and

(b) first biasing means disposed within said seat tube to support said post and provide cushioning action for said post and said bicycle seat by compression of said biasing means; and

(c) a movable platform disposed within the seat tube for axial movement within defined limits therein for support of said post and said biasing means; and

(d) second biasing means having first and second ends, with said first end operatively fixedly attached to the seat tube, and said second end attached to ends of said movable platform extended out of the seat tube to provide a cushioning action for the platform by extension of said second biasing means.
