DESCRIPTION

UNIVERSAL ADJUSTABLE SEAT

Field of the invention

The present invention refers to an adjustable universal seatpost that has a universal, practical and inexpensive mechanism that allows to adjust the seatpost in height in a simple and effortless way. The seatpost is used in the sports equipment industry, specifically for cycling.

Background of the invention

When you want to adjust the height of the saddle of a bicycle, it can be done by getting off the bike and using the mechanical clamp system, which is quite uncomfortable and limits the use since you have to stop to change the position of the saddle.

There is another mechanism that allows you to adjust the height of the saddle, which are the hydraulic seatposts, in which pressing a button on the handlebar of the bicycle allows you to raise and lower the saddle. These seatposts present a problem that is the high price, which limits access to them by a public with less economic contribution.

In addition, bicycle seatposts are not universal, but their size ranges in a range of diameters that limit the use of a certain type of seatpost for the public that for some reason may want to change the seatpost of their bicycle and this means a trouble finding a suitable size.

So, today we can classify the various types of different seatposts into two groups:

- clamp or manually adjustable seatposts, and

- telescopic or hydraulic seatposts.

First of all, the manual adjustment posts have a very simple operation. At the junction of the frame with the seat post, there is a clamp that is tightened or loosened depending on how you want to adjust the height of the saddle. The clamp consists of a lever that is attached to a screw and when you loosen the lever you have the possibility of tightening or loosening said screw, thus allowing more or less play to the saddle. This clamp appears in the document with application number P201500522 that is called clamp for fixing the position of a seat post relative to a bicycle frame.

In the other large group of seatposts (those that are not manually adjustable), there are the aforementioned telescopic seatposts. In the market for telescopic seatposts there are several documents presented throughout the years 20011 and 2012, which describe several electronically controlled telescopic seatposts. Specifically, document US1151310011B2 describes a telescopic seatpost system equipped with a small motor that allows us to autonomously regulate the height by controlling said motor with a remote control from the handlebar.

Currently there are numerous projects that present alternative models of the adjustable seatpost using wireless control systems and a wireless control, or air chambers with oil reservoir. These systems, which are valid alternatives for teams with large resources, are probably not available to the individual bicycle user, since they are high-priced systems.

The object of the invention is to develop a universal and mechanically adjustable height seatpost, which is available to all users.

Description of the invention

The object of the invention is an adjustable universal seatpost comprising a body such that the body comprises a toothed wheel housed inside the body, and a rack where the toothed wheel of the body itself rests, where the toothed wheel and the rack are configured to provide a controlled movement of the body.

The seatpost also comprises a hook configured to block the rotation of the sprocket, a steel cable that runs through the interior of the body and that comprises a handle at one end and a plurality of branches at the ends of which are located anti-slip pads configured to contact with a frame of a bicycle through some housings of the body and prevent the seatpost from slipping on said frame.

In the universal adjustable seatpost object of the invention, the non-slip pads comprise rectangular prisms, covered with a non-slip rubber.

In the universal adjustable seatpost object of the invention, the hook has as its axis a metal rod, such that at rest, the hook fits between the teeth of the sprocket thus blocking its movement and, therefore, the height of the seatpost.

In the universal adjustable seatpost object of the invention, the steel cable houses a washer and the body houses at least one spring, such that a pull from the handle makes the washer contact and push the springs and move the non-slip pads that come out of the body housings reducing the diameter of the seatpost body, and when there is no pull on the handle, the springs push the washer and the anti-slip pads return to the body housings.

Detailed description of the invention

The object of the invention is an adjustable universal seatpost, which comprises a body (1) that houses a rack and pinion mechanism such that by means of a toothed wheel (2) located in a housing (3) in the form of a bulge in the body (1 ) of the seatpost supported on a rack (4) of the body itself (1) allows the controlled movement of the rack (4) housed in the body (1).

Attached to the body (1) we find a hook (5) that blocks the rotation of the sprocket (2) and allows the seat post to be locked at a specific height; When you want to change the height, it is necessary to act on the hook (5) so that it stops blocking the toothed wheel (2) and the saddle can go up and down.

The hook (5) has as its axis a metal rod that allows it to oscillate, at rest, the hook (5) fits between the teeth of the sprocket (2) thus blocking its movement and, therefore, the height of the seat post. To adjust the height, the hook is activated so that it releases the sprocket (2) and can rotate. When the hook (5) is actuated, it is held by a magnet (6) attached to the inside of the body (1), thus avoiding the inconvenience of holding the hook (5) while adjusting the height. Once the desired height is reached, the hook (5) is released and it locks the gear again.

In the same way, to adapt the seatpost to different bicycle frame diameters, the seatpost object of the invention comprises non-slip pads (7) that are located on different branches (8) of a steel cable (10) that also has a handle ( 11) at an opposite end.

The steel cable (10) has a washer (13) so that it runs inside the body (1) of the seat post and is supported by springs (12) fixed to the inside of the body (1) through the washer (13). The interior of the body (1) also has a series of pins (9) that serve so that the steel cable (10) or rather the branches (8) of the steel cable bend and rest on the pins (9) to hold the anti-slip pads (7).

The non-slip pads (7), in the preferred embodiment of the invention, are rectangular prisms, covered with a non-slip rubber, such that they prevent the body (1) of the seatpost from sliding inside the bicycle frame due to the weight of the user.

The body (1) of the seatpost comprises housings (14) configured to house the anti-slip pads (7).

At the moment in which the handle (11) is activated, the washer (13) attached to the steel cable (10) pushes the springs (12) and in this way the non-slip pads (7) contract and are inserted into the housings (14) of the body (1), thus reducing the diameter of the body (1) of the seatpost.

Once the body (1) of the seat post is housed in the bicycle frame, the handle (11) is released so that the non-slip pads (7) expand against the walls of the frame itself and the body (1) of the seatpost fits perfectly inside the frame.

The upper part of the seatpost comprises a retractable rubber (15) that lengthens and contracts as required by the movement of the rack (4), so that the seatpost does not have an unsightly appearance and that said rack ( 4) not visible when the height is adjusted.

Claims (4)
