Description

COMPRESSED GAS COOLING DEVICE IN COUPLING FOR CYCLING AND TRIATHLON Object of the invention The present invention relates to a cooling device implemented in a grip of an aerodynamic coupling installed on the handlebars of a bicycle so that the user can cool his arms by means of bursts of cold gas over the arms during long-distance races. BACKGROUND OF THE INVENTION It is well known that, in cycling, heat is one of the main factors affecting a cyclist's performance, especially during long-distance events in the hottest times of the year. For this reason, any type of cooling system is considered necessary during the race, both on the bike and on the run. Cooling is essential for achieving athletic goals. In this context, cooling pads, cooling headbands, and air ventilation systems are currently used. Due to the high temperatures that cyclists endure, whether from the ambient temperature or from the physical activity itself, it is a determining factor for the health and performance of the athlete. In cycling and triathlon, where athletes adopt an aerodynamic position on the bike, their arms are typically supported by aerodynamic grips. These grips consist of a cover (usually made of carbon fiber) that provides a significant aerodynamic advantage. However, this cover also blocks the airflow generated while cycling, leading to a feeling of warmth for the athlete. Water sprays, thermal pads, and ice packs are available on the market. However, none of these solutions are entirely effective. Water sprays can dampen electronic devices and the cyclist's glasses. Thermal pads have a limited lifespan, as they cease to function once the cold dissipates, just like ice packs. BRIEF DESCRIPTION OF THE INVENTION The solution to the technical problem is achieved by the subject matter of independent claim 1, which defines the invention per se. This specification describes a cooling device attached to a bicycle handlebar, comprising a hollow grip with an actuator connected to a compressed gas cartridge. Ventilation slots are located on the rear side of the grip, directed towards the area of ​​the attachment where the user's arms rest. The compressed gas cartridge, the actuator, and the ventilation outlets form an integrated circuit within the grip. To cool down, the user activates the actuator, producing a burst of rapidly expanding gas that decreases in temperature (due to the Joule-Thomson effect) inside the grip until it exits through the ventilation slots, thus cooling the user's forearms. BRIEF DESCRIPTION OF THE DRAWINGS To complement the description being made and in order to help a better understanding of the characteristics of the invention, a series of drawings are included as an integral part of said description, in which, for illustrative and non-limiting purposes, the following has been represented: Figure 1-. Shows a side view of a coupling device (1) attached to a handlebar (2) of a bicycle (3). Figure 2 shows a plan view of the coupling device (1). A handle (4) associated with an extension body (5) can be seen. A longitudinal adjustment slot (13) of the coupling (1) is also visible. Figure 3 shows an exploded perspective view of the coupling device (1). The handle (4) containing the bicycle gear control devices (12) and the left activation button (6) of the cooling device can be seen. Figure 4.- Shows an exploded perspective view of the grip (4) in which you can see the cartridge (8) that is inserted into the cavity (7), also the activator (6), the computer support (9), a vent (10) and the feeding fixings (11). Figure 5 shows a plan view of the internal workings of the integrated circuit in the grip (4). The location of the actuator (6), to which the cartridge (8) is connected, is visible. Also visible are the computer mount (9), the ventilation (10), and the power supply connections (11). A representation of the integrated circuit's operation inside the grip (4) can be seen. When the actuator (6), which is connected to the cartridge (8), is activated, the compressed gas inside the cartridge (8) is released into the grip (4). This gas expands rapidly, significantly decreasing its temperature. This cool gas circulates rapidly inside the grip (4) and exits through the ventilation (10), thus cooling the user's arms. Detailed description of the invention In view of the figures discussed and according to the numbering adopted, we can observe a coupling device (1) for bicycles, especially triathlon bicycles, which is attached to the handlebar (2) of the bicycle (3) as can be seen in figure 1. The coupling device (1) consists, on the one hand, of an extension body (5) and a longitudinal adjustment slot (13) of the coupling (1) and, on the other hand, of a detachable handle (4). The detachable handle (4) is attached to the longitudinal center of the extension body (5). This handle (4) consists of a single, central, and symmetrical grip. The bicycle gear shift control devices (12) are located on the upper surface of the grip area of ​​the handle (4). The actuator switches (6) are located on either side of the grip. The computer mount (9) is visible in the upper center of the handle (4). In this embodiment, vents (10) are located on either side of the handle (4). Because the handle (4) is hollow, the vents (10) are internally connected to the actuator (6). Fasteners (11) for attaching food pouches for the user are located on the back of the handle (4). The operation of this device is based on the Joule-Thomson principle, in which a compressed gas drastically decreases in temperature upon expansion. When the actuator (6) is activated, the compressed gas is released very rapidly and occupies the area of ​​lowest pressure. On one hand, the cool gas escapes through the vents (10), cooling the user's arms. On the other hand, during expansion, the gas absorbs thermal energy from the surroundings, resulting in the cooling of the handle (4). This is also beneficial to the user, in terms of cooling, as they are holding the handle (4) cooled by the gas.
