Description
CHASIS AUTOPROPULSADO PARA SALVAR DESNIVELES SELF-PROPELLED CHASSIS TO SAVE LEVELS
Descripción La presente invención consiste en un chasis autopropulsado para salvar desniveles, cuya conformación y características le confieren unas ventajas de fabricación y uso que mejoran de forma sustancial los chasis existentes en el estado de la técnica y en el mercado. El chasis autopropulsado para salvar desniveles, destinado principalmente al acople con cochecitos de bebé y carros para la compra, comprende medios de autopropulsión mediante energía eléctrica y seis ruedas motrices situadas en el eje posterior y que permiten subir y bajar desniveles del tipo escaleras o pendientes. Estado de la técnica Description The present invention consists of a self-propelled chassis to overcome unevenness, whose conformation and characteristics confer manufacturing and use advantages that substantially improve the existing chassis in the state of the art and in the market. The self-propelled chassis to save unevennesses, destined mainly to the coupling with baby strollers and shopping carts, includes self-propelled means by means of electric power and six driving wheels located on the rear axle and that allow to raise and lower slopes of the stairs or slopes type. State of the art
Actualmente, la mayoría de los chasis que se vinculan a carros para las compra o a cochecitos de bebés que existen en el mercado son de propulsión manual, es decir, por la persona que lleva el artefacto por calles y aceras, debiendo ejercer una considerable fuerza para subir pendientes, rampas y sobre todo, prácticamente es imposible subir peldaños o escaleras con el carro o cochecito cargado, a no ser que se cuente con la ayuda de una segunda persona. La maniobra resultante suele ser que una persona levante el chasis por la parte delantera y otra persona lo levante por la parte trasera, con el inconveniente que ello supone, no solo de ejercer una fuerza considerable para levantar el carro o cochecito a peso sino por el más que evidente riesgo de desequilibrio y de volcado. Currently, most of the chassis that are linked to shopping carts or baby strollers that exist in the market are hand-propelled, that is, by the person who carries the device through streets and sidewalks, having to exert considerable force to Climb slopes, ramps and above all, it is practically impossible to climb steps or stairs with the car or stroller loaded, unless you have the help of a second person. The resulting maneuver is usually that a person lifts the chassis from the front and another person lifts it from the rear, with the inconvenience that this entails, not only exerting considerable force to lift the car or stroller by weight but by the more than obvious risk of imbalance and dump.
Descripción de la invención Así pues, la invención que se presenta tiene por objeto un chasis autopropulsado para salvar desniveles que comprende un mecanismo que da solución a los problemas descritos. DESCRIPTION OF THE INVENTION Thus, the present invention has as its object a self-propelled chassis to overcome unevennesses comprising a mechanism that gives solution to the described problems.
Este mecanismo se concreta en unos medios de autopropulsión mediante energía eléctrica y seis ruedas motrices situadas en el eje posterior y accionadas por engranajes y/o cadenas desde un motor convencional.
Este mecanismo está alimentado por baterías recargables y/o supercondesadores, los cuales cumplen la misma función de almacenar energía pero a menor costo, menor tiempo de carga, mayor duración y menor peso y volumen. En cualquiera de los casos, estos medios de alimentación se ubican preferentemente en la parte inferior del chasis, el cual es accionado desde el manillar, con controles fácilmente accesibles y de comando táctil. This mechanism is specified in self-propelled means by means of electric power and six driving wheels located on the rear axle and driven by gears and / or chains from a conventional engine. This mechanism is powered by rechargeable batteries and / or supercondensers, which fulfill the same function of storing energy but at a lower cost, shorter charging time, longer life and less weight and volume. In any case, these feeding means are preferably located in the lower part of the chassis, which is operated from the handlebar, with easily accessible controls and tactile command.
El chasis autopropulsado para salvar desniveles comprende, asociado a su estructura, un dispositivo de seguridad pasiva de carácter automático del tipo airbag, formado por una bolsa de aire adecuadamente dimensionada y preparada para cubrir preferentemente la zona frontal de la bolsa o del cubículo para bebés que son portados por el chasis ya referenciado, de modo que en caso de caída o golpe fuerte, dicho airbag proteja las pertenencias transportadas en el carro de la compra o la criatura instalada en el cochecito. The self-propelled chassis to save unevenness includes, associated with its structure, an automatic passive safety device of the airbag type, formed by an air bag properly sized and prepared to preferably cover the front area of the bag or the baby cubicle that they are carried by the chassis already referenced, so that in the event of a fall or strong blow, said airbag protects the belongings transported in the shopping cart or the creature installed in the stroller.
Además, el chasis autopropulsado comprende otros medios de seguridad pasiva, lo cual supone una medida de seguridad complementaria. Dichos medios son de carácter manual, siendo medios de enganche o sujeción que lo vinculan directamente al usuario que comanda o controla el susodicho carro, por ejemplo, una correa, cinta o similar, o bien de carácter electrónico en base a un chip integrado en un elemento de soporte del tipo pulsera, colgante, llavero, tarjeta o similar que se comunica con el carrito e identifica a la persona que lo está manejando, de forma que solo permite que dicha persona acceda a los controles de mando y los manipule para mover el chasis. En caso que otra persona intente maniobrar el chasis, éste no responde a los mandos y se activa una alarma óptica y/o sonora graduable. Lógicamente, este sistema de seguridad electrónico puede ser desactivado a voluntad del usuario. In addition, the self-propelled chassis comprises other passive safety means, which is a complementary security measure. Said means are of a manual nature, being attachment or securing means that link it directly to the user who commands or controls the said car, for example, a belt, tape or the like, or of an electronic nature based on a chip integrated in a support element of the type bracelet, pendant, keychain, card or similar that communicates with the cart and identifies the person who is driving it, so that it only allows that person to access the control controls and manipulate them to move the chassis. If another person tries to maneuver the chassis, it does not respond to the controls and an adjustable audible and / or audible alarm is activated. Logically, this electronic security system can be deactivated at the user's discretion.
Esta característica resulta también notablemente interesante para evitar sustracciones, por ejemplo del carro de la compra, o para no separarse accidentalmente o por otras circunstancias, del cochecito de bebé. This feature is also remarkably interesting to avoid subtractions, for example from the shopping cart, or not to accidentally separate or for other circumstances, from the baby carriage.
Igualmente el chasis que se reivindica comprende al menos un puerto de conexión eléctrica, en especial en la aplicación para cochecito de bebé, el cual permite acciones como, por ejemplo, calentar biberones o conectar una manta eléctrica. Likewise, the chassis that is claimed comprises at least one electrical connection port, especially in the application for a baby carriage, which allows actions such as, for example, heating bottles or connecting an electric blanket.
Como se ha comentado anteriormente, los medios de alimentación preferentes asociados al chasis autopropulsado son baterías recargables y/o supercondesadores
y se contempla que dicho chasis incorpore placas o paneles solares fotovoltaicos para la recarga de dichos medios de alimentación. As mentioned above, the preferred power media associated with the self-propelled chassis are rechargeable batteries and / or supercondensers and it is contemplated that said chassis incorporates photovoltaic solar panels or panels for recharging said feeding means.
Por último señalar que el chasis autopropulsado comprende igualmente al menos un punto de enganche o sujeción adicional que permite asociar más de una bolsa de transporte, siendo dichas bolsas de de una sola embocadura, de doble embocadura e interior compartimentado y/o de superficie acolchada. Esta característica resulta especialmente interesante en especial cuando se vincula a un carro de la compra pero es igualmente válida cuando se vincula al cochecito de bebé, ya que de este modo se amplía la capacidad de uso del chasis. Finally, it should be noted that the self-propelled chassis also includes at least one additional attachment point that allows more than one transport bag to be associated, said bags being of a single mouth, double mouth and compartmentalized interior and / or padded surface. This feature is especially interesting especially when it is linked to a shopping cart but it is equally valid when it is linked to the baby carriage, as this increases the usability of the chassis.

Descripción de una realización preferida En estas figuras se describe el chasis autopropulsado para salvar desniveles aplicado a dos artículos transporte de referencia puesto que son usados de forma habitual en entornos en los que se hace necesario salvar desniveles, en especial escaleras de edificios sin ascensor y pendientes en poblaciones y que se concretan en un carro de la compra y en un cochecito de bebé. DESCRIPTION OF A PREFERRED EMBODIMENT These figures describe the self-propelled chassis to save unevenness applied to two reference transport items since they are used routinely in environments where it is necessary to save unevenness, especially stairs of buildings without elevator and slopes in populations and which are specified in a shopping cart and in a baby carriage.
De acuerdo con las figuras 1 , 2 y 4, en donde se vincula el chasis reivindicado a un carro de la compra, y con las figuras 5, 6 y 7, en donde se vincula el chasis reivindicado cochecito de bebé, el objetivo de esta invención es impulsar el carro o el cochecito de bebé con un mecanismo electromecánico, alimentado por baterías (3) recargables ubicadas en la parte inferior, comandado desde el manillar, con controles de mando (2) fácilmente accesibles y de comando táctil donde en principio deberá al menos apoyar la mano quien lleve el carro o el cochecito para accionar los controles, de lo contrario el conjunto de las ruedas motrices (1) se bloquearán automáticamente para impedir el traslado accidental del mismo por desniveles del suelo, y así evitar accidentes. According to Figures 1, 2 and 4, where the claimed chassis is linked to a shopping cart, and with Figures 5, 6 and 7, where the claimed baby stroller chassis is linked, the purpose of this invention is to drive the car or the baby carriage with an electromechanical mechanism, powered by rechargeable batteries (3) located at the bottom, commanded from the handlebar, with easily accessible control controls (2) and tactile command where in principle you should At least support the hand who carries the car or the stroller to operate the controls, otherwise the set of the driving wheels (1) will be automatically locked to prevent accidental movement of the same by uneven ground, and thus avoid accidents.
En la figura 3 se muestra una vista detalle de las seis ruedas motrices situadas en el eje posterior. Este sistema de seis ruedas motrices (1), tres a cada lado del carro o del cochecito, accionadas por engranajes y/o cadenas desde un motor convencional del tipo utilizado en sillas de ruedas para discapacitados, sirve tanto para el traslado normal por calles y aceras horizontales, como para ayudar a subir pendientes o rampas de accesos a edificios en un sentido de giro (4) de las susodichas ruedas motrices (1), como para subir escaleras, llevando el carro en sentido contrario, es decir, hacia atrás, accionando en este caso todo el conjunto de las seis ruedas motrices (1). El comando tiene tres posiciones hacia delante (paso lento, paso normal y paso rápido) para adaptarse a las distintas necesidades de cada ocasión. En la aplicación para cochecito de bebé se añade una cuarta posición "Mecedora" en la cual
el aparato hace un pequeño y suave movimiento atrás-adelante para realizar el efecto señalado, permitiendo en este caso soltar el manillar y no dejando que el carro se desplace mas allá de lo permitido por este movimiento de vaivén . En cualquier caso, el chasis incluye la opción de desconectar todo el sistema para que actúe como un carro o cochecito de bebé convencional, es decir accionado manualmente. A detailed view of the six driving wheels located on the rear axle is shown in Figure 3. This six-wheel drive system (1), three on each side of the car or stroller, driven by gears and / or chains from a conventional motor of the type used in wheelchairs for the disabled, serves both for normal road and street transport. horizontal sidewalks, such as to help climb slopes or access ramps to buildings in a direction of rotation (4) of the said driving wheels (1), such as to climb stairs, carrying the car in the opposite direction, that is, backwards, driving in this case the whole set of the six driving wheels (1). The command has three forward positions (slow step, normal step and fast step) to adapt to the different needs of each occasion. In the application for baby stroller a fourth position "Rocking chair" is added in which The device makes a small and smooth back-forward movement to perform the indicated effect, allowing in this case to release the handlebar and not allowing the car to move beyond what is allowed by this reciprocating movement. In any case, the chassis includes the option of disconnecting the entire system to act as a conventional carriage or baby carriage, that is, manually operated.
Cuando el carro o el cochecito de bebé se topa con un escalón o bordillo de acera, se lo utiliza en dirección contraria, es decir "marcha atrás". Al accionar el control: "Subir peldaños", automáticamente el mecanismo de accionamiento de las ruedas hace que todo el conjunto de las seis ruedas motrices (1) gire en el sentido correcto, subiendo el obstáculo hasta posicionarse la siguiente rueda en el borde superior del mismo, salvando así el desnivel o los escalones de la escalera. En el caso de escaleras, el sistema funcionará con el control y ayuda de la persona que lleva el vehículo para mantenerlo en posición horizontal, ya que sólo tendrán contacto con el suelo las seis ruedas motrices (1). When the car or the baby carriage runs into a step or curb, it is used in the opposite direction, ie "reverse." When the control is activated: "Climb steps", the wheel drive mechanism automatically causes the entire six-wheel drive assembly (1) to turn in the correct direction, raising the obstacle until the next wheel is positioned on the upper edge of the same, thus saving the slope or the steps of the stairs. In the case of stairs, the system will work with the control and help of the person carrying the vehicle to keep it in a horizontal position, since only the six driving wheels (1) will have contact with the ground.
