Description

Bicycle seat or exercise bike

The invention relates to the design of a vehicle seat, preferably a bicycle. The claimed invention can also be used for exercise bikes.

It is known that there are two problems that arise when riding a bike with a traditional saddle: excessive pressure at the point of contact between the surface of the cyclist’s body and the surface of the saddle and the unstable landing of the cyclist. The cause of these problems is the limited area of contact between the surface of the cyclist and the surface of the saddle. Similar problems arise when using an exercise bike.

An ordinary person on a modern bike can easily overcome a distance of 40-70 km. However, after traveling 10–15 km, the cyclist feels a decrease in ride comfort due to an uncomfortable saddle, which leads to fatigue, reduced speed and reduced ride time. Typically, bicycle manufacturers use traditional saddle designs. Known designs of the bicycle saddle are made in the form of a fixed platform with a horn protruding forward. In this case, the platform can be both flattened and volume, more close to the anatomical features of a person. While the process of improving the design and performance of other components of the bike is continuous, the shape of the saddle has only recently been noticed. Bicycle manufacturers began to produce improved models, improving already known designs, while claiming that the pressure on the sensitive tissues of the human body is reduced. However, the optimization of shape and size and the use of modern materials only partially solved these problems.

From the prior art (SU 937263, publ. 06/23/1982) is known a two-wheeled vehicle seat, fitted with a seatpost bracket connected by means of a lock to a frame, including the front and rear frames, which are interconnected by longitudinal slats, and horizontal springs above which posted tire. Additionally, in order to improve the comfort of landing and driving by changing the shape of the seating surface of the saddle, the frame is provided with a longitudinal bar located in the rear part that can be moved along the transverse guide, cross bar and vertical spring-loaded a rod mounted in a transverse guide and connecting the latter with a transverse bar mounted for vertical movement, while the frame is provided with an additional lock hinged to the front frame and mounted on the vehicle frame with the possibility of longitudinal movement and fixation, and the lock connecting the seatpost with the frame, made with the possibility of longitudinal movement and fixation of the frame relative to the seatpost bracket.

The prior art attempts to eliminate the excess pressure of the surface of the saddle of a two-wheeled vehicle on the human body in the area of the tazopakh by creating saddles completely new configuration. So, for example, in WO 00/78595 Al, publication date 12/28/2000, a bicycle saddle is described, comprising a frame and a seating position in the form of two separate parts, each of which has front and rear sides, with the front side hinged on the frame , and the back side is made with the possibility of adjusting the angle of inclination to the horizontal plane.

In WO 01/26954, published on April 19, 2001, an improved bicycle saddle is described, consisting of two separate anatomical supports to accommodate the cyclist's buttocks. The connection between the divided supports is carried out with the help of a bridge located at the bottom and attached with the help of iron plates to the lower part of the corresponding supports by means of ordinary fastening elements. Fastening the lower part of the specified bridge to the axis is provided by means of a conventional bracket, with the possibility of changing the position of the seat.

Despite the significant attempts being made to create fundamentally new designs of the saddle, the proposed solutions have at least two drawbacks. First, excessive pressure at the point of contact between parts of the saddle and the body of the cyclist, and second, the instability of the cyclist.

Thus, the problem of creating a bicycle or exercise bike seat that satisfies the requirements of convenience and minimal negative impact on the human body remains unresolved.

The objective of the present invention is to create a bicycle seat or an exercise bike, which allows to increase the contact area of the cyclist’s body and the seat while reducing pressure at the points of contact, thereby increasing ride comfort and stability of the cyclist during movement. The problem is solved with the help of a bicycle seat (exercise bike), including the bicycle saddle (exercise bike) directly mounted on the seat tube, and additionally attached to the bicycle seat tube (exercise bike), supporting the device in the form of two supports symmetrical relative to the saddle, interconnected movably.

The connection of the supports in the form of a rocker is made in two preferred embodiments of the invention.

Another object of the invention, solving the task, is a device, additionally mounted on a bicycle (exercise bike), by attaching to the seat tube of a bicycle (exercise bike), made in two versions.

The first option consists of two symmetrical supports with respect to the saddle, interconnected by a four-element rocker arm consisting of two transverse (along the bicycle) interconnected in the central part of rigid elements of equal length and two vertical rigid elements of equal length movably fixed on the ends these transverse elements with the possibility of simultaneous simultaneous displacement along the vertical, in its central part the rocker arm is equipped with a device for fastening to the seatpost tr Bike, while the supports are installed at the ends of the vertical elements with the possibility of tilting in the direction of travel.

In a preferred embodiment, the connection in the central part of the rocker arm is made in the form of a standard fork with the possibility of changing the angle of inclination of the fork relative to the horizontal. In turn, the plug is installed with the ability to rotate and secure relatively adjustable removal of the bracket, which is connected to the bracket fixed on the seat tube. The above possibilities of adjusting the position of parts of the device relative to each other allow the installation of the device, taking into account the individual characteristics and needs of each rider. It will be apparent to those skilled in the art that the compound can be made by any other known method.

In the following preferred embodiment of the claimed device, the transverse elements are interconnected at a distance of from 1/10 to 2/3 of the length of the transverse element, most preferably from 1/10 to 1/7. The distance between the transverse elements is performed so that when the bicycle moves in the extreme (upper and lower) positions of the supports, it is impossible to grind the transverse elements. The second option consists of two symmetrical supports with respect to the saddle, interconnected by a single-element rocker arm. In its central part, the rocker is movably connected to the attachment device to the seatpost. When this support is installed at the ends of the rocker arm with the possibility of tilting on the axes in the direction of travel.

In the most preferred embodiment of the invention, the supports are made at an angle to the saddle, which ensures their uniform contact with the cyclist's body.

In yet another most preferred embodiment, the supports are made of a soft material fixed over a rigid base. The person skilled in the art it is obvious that the supports can be made of any material used for the saddle of the bike. The material used for the supports may be identical or different from the material of the saddle.

The size and shape of the supports can be arbitrary and are selected depending on the purpose of the bike: road, tourist, sports, etc.

Before the start of the trip, the arrangement of the device relative to the saddle can be adjusted in height by displacing and rigidly fixing the bracket along the seat tube, as well as tilting due to the rotation and securing of the fork relative to the extension of the bracket in the desired position.

In the claimed seat, it is possible to use any traditional saddle of known construction.

The objects of the invention are also a bicycle and an exercise bike, equipped with a seat according to the present invention.

Fig. 1 schematically shows the first preferred embodiment of the device additionally attached to the seat tube of a bicycle with a four-element rocker arm.

In fig. 2 schematically shows a rear view of the specified device at the moment of movement.

In fig. 3 schematically depicts a second preferred embodiment of the device additionally attached to the seat tube with a single-element rocker arm.

In fig. 4 schematically shows the rear view of the specified device at the moment of movement.

The following describes the first preferred embodiment of the present invention, not limiting its scope. The claimed seat includes a saddle (not shown in the figure) and an additional device attached to the seatpost (1) of the bicycle. The specified device contains two symmetrical with respect to the saddle support (2, 3) mounted on the transverse axes. The supports are interconnected by a rocker arm, consisting of two rigid elements (4, 5) along the bicycle path (4, 5) and two vertical rigid elements (6,7). These transverse elements are of equal length. They are fastened together in their central part at a distance of 1/10 of the length of this element. The fastening can be made in the form of a standard fork (8) with the possibility of changing the angles α between each of the transverse elements (4, 5) of the rocker arm and the fork (8). These vertical elements are of equal length. These vertical elements are movably fixed at the ends of the said transverse elements, forming the right and left arms of the rocker arms, respectively. Vertical elements and transverse elements are connected with the possibility of simultaneous simultaneous displacement with a change in the angle α and the internal one-sided angle β between the transverse and vertical elements, respectively. The plug (8) is connected to the removal (9) of the bracket (10). Plug connection

(8) with the removal of (9) is made movable with the possibility of changing the position of the device relative to the transverse axis (angle γ), i.e. in the direction of the cyclist. The removal (9) is attached to the bracket (10) with the possibility of changing the angle ε relative to the seat tube (1).

In the second preferred embodiment, the implementation of the specified device contains two symmetrical with respect to the saddle support (2,3) mounted on the transverse axes along the edges of the single-element rocker (11). In its central part, the single-element rocker (11) is connected to the removal of the bracket (9) by means of the longitudinal axis with the possibility of changing the angle α.

The claimed seat in the first embodiment works as follows. Before starting the trip, it is advisable to install the device in the desired position for a particular user relative to the saddle. The height of the device placement relative to the saddle is adjusted by raising or lowering the device by mounting the bracket (10) on the seatpost (1) and changing the position of the stem.

(9) about the seat tube (1). The inclination of the device relative to the seat is adjusted by changing the position of the fork (8) relative to the offset (9) of the bracket (10). The location of the device relative to the seat is also regulated by changing the length of the stem (9). Then the device is rigidly fixed to the seat tube (1) with the help of the bracket (10). The cyclist sits in the seat and starts moving. In this case, symmetrical supports 2 and 3 are located under the left and right thighs of a person, respectively, providing an additional area of contact, creating additional support for the person and taking on part of his weight.

We describe the unit of motion, for example, as follows (as schematically indicated in Fig.2). The left leg of the person is located on the pedal and pushes it down, the thigh of the left leg is lowered, while the position of the support 2 and the corresponding vertical element 6 is changed as follows. Bearing 2 bends forward on the axis in the direction of travel and simultaneously with element 6 goes down, i.e. the position relative to the transverse elements (4, 5) changes with a change in the angle α. The left shoulder of the rocker falls down, and the angle α between the transverse elements (4, 5) of the rocker and its vertical element (6) becomes sharp. At the same time, the right shoulder of the rocker rises, and the angle β between the transverse elements (4.5) of the rocker and the vertical element (7) becomes obtuse. This synchronously changes the position of the support (3). At the next moment of movement, the right leg of the person moves downwards, repeating the movement of the left leg, and the left leg up, repeating the movement of the right. At the same time, the vertical elements 6 and 7 move only up and down relative to each other and practically maintain parallelism.

The claimed seat in the second version works as follows. We describe the unit of motion (as schematically indicated in Fig. 4). The left foot pushes the pedal down, the left thigh descends, the support 2 leans forward on the axis while moving and simultaneously with the left end of the rocker arm goes down, i.e. the position of the rocker relative to the seat changes with a change in angle α The left shoulder of the rocker (11) goes down, and the angle α between the rocker and the vertical becomes sharp. At the same time, the right shoulder of the rocker rises, and the angle β between the rocker and the vertical becomes blunt. At the next moment of movement, the right leg of the person moves downwards, repeating the movements of the left leg, and the left foot upwards, repeating the movements of the right leg. In this case, the supports (2,3) move up and down, forward and backward relative to each other.

The movement of the supporting supports corresponds to the movement of the human body - the hips and pelvis, thanks to the use of the mechanism of the rocker arm and the mobility of the supports on the vertical elements. At any position of the cyclist's legs, the pressure on the supports is the same, since the device proposed together with the saddle of the bicycle creates a design of an ergonomic seat with anatomical shapes. The claimed device characterized by ease of implementation, ease of use, increased stability. At the joints of elements during movement, friction is practically absent. Thanks to the use of the rocker mechanism and the mobility of the supports on the vertical elements, the movement of the legs and the supporting supports is achieved. The pressure on the supports at any position of the legs is the same. The device does not complicate the process of landing and disembarking. In this case, the device proposed according to the invention makes it possible not to expend efforts on overcoming discomfort, as a result of which the speed and duration of the trip increases.

The device according to the invention has a seat-independent mount - a standard seatpost bracket, can be used on any bikes, including bikes in use, on exercise bikes.

The use of the proposed seat is possible for bicycles and simulators. It does not require a change in their design.
