Definitions
- the present invention relates to bikes of the so-called “full suspension” type (mountain bikes with central rear suspension system on the frame, hence the need for a cut tube), the rear suspension of which requires a seat tube for the partial bike frame (cut ).
- the height of the saddle is adjusted in known devices by free sliding of the rod in the tube. To avoid exceeding the safety limit during this sliding, the manufacturers specify it by a marking on the rod. Usage has learned that this marking does not prevent the limit from being exceeded.
- Many accidents on bikes of the so-called “full suspension” type are due to non-compliance with the maximum limit of exit from the standard seatpost under the term: "MINI INSERT" or "MINI INSERTION".
- the device according to the invention comprises a connecting rod connecting a means forming a fixed point positioned inside the seatpost, not far from the base thereof, to a washer positioned at the base of the seat post, said connecting rod sliding through the means forming a fixed point.
- the upper part of the connecting rod above the fixed point means is provided with a compression system trapped by a stop means at its upper end of said connecting rod and by the fixed point means positioned in the seatpost at the bottom of the connecting rod.
- - Fig. 1 shows a vertical sectional view of a suspension seatpost locking device according to a preferred embodiment of the invention, seatpost lowered as far as possible into the frame tube
- - Fig. 2 shows a vertical sectional view of the device according to the invention shown in FIG. 1, seat post mounted to the maximum while respecting the safety zone.
- the device shown in the figures comprises a connecting rod 1 which connects: * a means 2 forming a fixed point positioned inside the seat rod 3 .4, not far from the base 5 thereof.
- Said means comprises at least one part fixed by known means such as a thread to the internal surface 6 of the hollow seat post 3 3.
- This means is provided with a through hole 7 allowing the connecting rod to slide 1.
- a washer 8 is positioned at the base 5 of the seat post.
- the upper part of this washer 8 is of diameter substantially smaller than the inside diameter of the seat post 3 so as to be inserted therein.
- the lower part of this washer 8 has a diameter substantially equal to the outside diameter of the seat post 3; in this way it comes to bear at the base 5 of the seat post 3.
- the upper part of the seat 1 is provided (surrounded), above the means forming a fixed point with a compression system in a first variant a compression spring 9 and at its upper end a stop means 10 such as a screw or a nut preventing the compression spring 9 from coming out of the rod 1.
- the lower part of the connecting rod 1 with the spring 9 is stopped by the means forming a fixed point 2 positioned in the seat post 3.
- the washer 8 leaves the contact of the base 5 of the seat post 3 and thanks to a lug 11 remains blocked in contact with the base 5 of the seat tube of the bicycle frame, the spring 9 compresses, leaving only a certain latitude of a few centimeters.
- the compression spring may be replaced by a known compression system of the hydraulic, oil and / or pneumatic type (compressed air).
- the invention has been described in connection with particular structures, it is in no way limited to it. Many variants remain possible, in particular from the point of view of the construction of the various elements by substitution-of technical equivalents, such as the replacement of the threaded part of the means 2 forming a fixed point by a double expander and combining or according to another variant.
