Abstract

SELF TIRE SUSPENSION FOR BIKES. Bicycle Suspension Seat Utility Model Patent consisting of an irregular perimeter cover, limited by an upper face, a side face, a lower face with at least one hole and a chamber-free inflatable volume over the face Juxtaposition lower and according to mounting is integrally associated with a rigid base plate for support and guide of the cover similar to the silhouette of said cover. This base has, in solidary form, two equidistant pieces, long and U-shaped to insert the fastening means to the bicycle barrel and also at least one through hole to introduce at least one valve for the inlet, retention and exit of air.

Description

Descriptive Report for Utility Model of PNEUMATIC SUSPENSION SEALING FOR BIKES

1) FIELD OF APPLICATION

The invention consists of a "Bicycle Air Suspension Saddle" consisting of a combination of structural elements providing a new ergonomic bicycle vibration dampening seat which can be adapted to the particular anatomy of each user.

2) BACKGROUND OF THE INVENTION

As is well known, bicycle harnesses must be of a construction which must be both rigid in order to withstand the forces applied to them and to be elastic to absorb the stresses caused by the surface of the road.

In the prior art there are various anatomical bicycle seats published in patent documents, including those that use air to inflate / deflate them and provide a more comfortable ride, and which deserve to be commented on for their importance; we can name

• US 5,938,277 A discloses an inflatable pneumatic seat with an inner valve to inflate it.

• US 5,419,612 discloses a bicycle seat which contains a plurality of inflatable cells inside. They are connected to each other and to three fluid conduits that inflate to a greater or lesser extent to each cell. The user can selectively adjust the degree of inflation, according to the use of the wheel.

• Spanish publication ES 1.025.985 discloses an inflatable seat where the particularity is that it can scale the amount of air incorporated in it, according to the convenience of the user, inflating and disinfecting it. It consists of an elastic blade properly mounted on a support or chassis forming one or more chambers that can be inflated by a valve incorporated in the inflatable blade itself. It is fixed perimeter on a chassis by means of rivets, forming an airtight bag. In addition, it is fixed longitudinally at its midpoint, determining two sectors or chambers communicated with each other. The inflation valve allows to inflate each sector and is conveniently installed.

• Australian publication AU B 28482/97 discloses an inflatable seat assembly consisting of a base support and an inflatable seat that links it to the bicycle.

3) PURPOSE OF THE INVENTION

It consists of a pneumatic suspension suspension for bicycles, with a rigid, ergonomic and economical construction in order to absorb the stresses caused by the road surface.

4) BRIEF DESCRIPTION OF THE FIGURES

Figure 1 shows a schematic view of the volume of the flexible cover.

Figure 2 shows a rear schematic view of the object of the invention.

Figure 3 shows an exploded and perspective view of all the elements that make up the object of the invention.

Figure 4 shows a schematic view of the assembly of the components of the object of the invention on the bicycle barrel.

5) DETAILED DESCRIPTION OF THE INVENTION According to the figures above, the characteristic elements that make up the air suspension seat for bicycles are:

1) Flexible material coverage

2) Top cover face

3) Side cover face

4) Bottom cover face

5) Hole in lower face

6) Inflatable volume

7) Rigid baseplate for support and cover guide (1)

8) Clamping ring

9) U-shaped Formwork Metal Parts

10) Bicycle saddle

11) Mounting attachments to the bicycle barrel (cross spanner / clamp - screw nut)

12) Valve for air inlet, check and outlet

13) Hole in rigid base plate (7)

14) Continuous rib of irregular perimeter for reinforcement of rigid base plate (7).

15) Weld points of the metal parts (9) to the metal base plate (7).

In all the figures the same reference numerals indicate the same or corresponding elements, wherein the bicycle air suspension saddle comprises a vulcanized injected single-piece comprising a cover (1) of irregular perimeter, limited by an upper chamber (2), a chamber side (3), a lower one (4) with at least one hole (5) and a chamber-free inflatable volume (6) on the lower face (4) and in juxtaposition according to the assembly is integrally associated a rigid base plate (7) for cover support and guide (1) similar to the silhouette of said cover (1), and said base has in solidarity two welded pieces (9) equidistant from each other, shaped and U-shaped to insert the securing means (11) into the barrel (10) of the bicycle and also at least one through hole (13) to insert at least one valve (12) for air inlet, retention and outlet.The manifold (7) is constructed of a material preferably made of a steel material 1010 and has, over a sector of its surface, an emerging continuous rib (15) of continuous development of irregular perimeter for structural reinforcement of said plate.

Claims (4)
