    DESCRIPTION

    Conveyor and stabilizer device for it

    SECTOR OF THE TECHNIQUE 5

    The present invention relates to a transport device, such as a children's car, a wheelchair, a stretcher, or any device for transporting sick, disabled or young children or any type of product that needs balanced transport. This device has active or 10 passive, but preferably active stabilizing elements.

    The invention also relates to an example of active stabilizer applicable to the device.

    STATE OF THE TECHNIQUE

    Babies and young children are frequently transported in cuckoo or stroller chairs. These means of transport have a series of wheels (3 or 4) and a platform that will be horizontal in cuckoo and a chair more or less inclined in the strollers. twenty

    When finding uneven ramp ramps or stairs, the father or mother must manually correct the position of the baby or child so that he is not uncomfortable or at risk of falling. This generally implies an upward or downward force on the handle of the cuckoo or chair so that only 25 are maintained on the front or rear wheels respectively.

    This type of movement is complicated by the great weight to lift and the risk of falling or overturning. Moreover, in three-wheelchairs it may be impossible to perform in one direction, which means having to turn the car to take the child back. 30

    There is also a series of adaptable children's cars that can be used as a cuckoo and as a stroller. These cars have a horizontal axis of rotation to vary the inclination of the basket or the chair, but it is not practical to adjust it each time you approach a change of slope. 35

    Wheelchairs present a similar problem, with the addition that they are not adjustable and that in addition the transported person is considerably heavier. In the case of ambulance stretchers, the risk is lower, since the transported person is lying down, but instead can carry drippers or other medical material that should not fall from the stretcher. 5

    In the transport of some products, such as the menu in a hospital, or when moving products in a factory, it may be necessary to stabilize the platform or upper envelope to prevent liquid from flowing out of the upper opening.

    No solution similar to the invention is known.

    BRIEF EXPLANATION OF THE INVENTION

    The invention consists of a conveyor device, for example a children's car, a wheelchair or a stretcher, according to the claims that resolves, in its different embodiments, the problems of the prior art.

    The conveyor device of the invention is of the type that has a frame with wheels, connected by a shaft to a platform or frame that supports the basket, mat or chair. It also includes an automatic stabilizer of the inclination of the platform or frame, which can be active or passive.

    As an example of a passive stabilizer, it is preferred to provide a counterweight at a lower level than the axis, joined by one or more braces to the platform or frame. If several straps are distributed between both sides of the shaft, to facilitate movement in both directions, they will preferably be attached to the platform or frame by joints and the straps on one side will be telescopic.

    Likewise, it is possible to perform the adjustable weight counterweight to adjust the total weight of the car.

    The preferred active stabilizer, which also forms a concept of the invention, is part of at least one tilt detector, and a motor activated by a microcontroller that corrects the tilt of the platform or frame based on the detector signal. If this is adjustable, it will be possible to adjust the inclination that will be stabilized.

    Preferably, the engine will correct the inclination of the platform or frame by means of a crank-crank mechanism.

    For a better understanding of the invention, the following figures are included.

    EMBODIMENTS OF THE INVENTION

    Next, an embodiment of the invention will be briefly described as an illustrative and non-limiting example thereof. twenty

    The invention relates to a conveyor device in general, but will be described with an example formed by a children's carriage that has been represented as a cuckoo. This car has a frame (1) with a series of wheels attached to a platform (2) on which the baby's basket is mounted on an axle (3). Where appropriate, the platform (2) will be shorter 25 to correspond to the base of a child seat, or more preferably it will be replaced by a frame (not shown) of the chair's contour.

    At the junction between the frame (1) and the platform (2) or frame an automatic stabilizer (4) of the inclination of the platform (2) or frame will be arranged around the 30 axis (3). This stabilizer (4) can be active or passive, each with its own advantages.

    An example of a passive stabilizer (4) comprises a counterweight (5) located below the axis (3), and weighing more than the sum of the child or children and their basket. Since the weight of young children is variable, the counterweight (5) will preferably be adjustable
    adding or removing elements. The counterweight (5) will be attached to the platform (2) or frame by the corresponding braces (6). Figure 1 shows two braces in "V" but can be any number.

    Depending on the effective length or orientation of each tie rod (6), the position to be stabilized will be horizontal (cuckoo) or inclined (chair). For this, it is recommended to have braces (6) from both ends of the platform (2) or frame, and that at least the brace (6) or braces (6) on one side are telescopic. In this case, the connection of the braces (6) to the platform (2) or frame will be through joints. Thus, by lengthening or shortening the braces (6) on one side of the platform (2) or frame, the equilibrium position varies.

    If the geometry of the cuckoo makes the platform (2) or frame below the axis (3), the braces (6) can be removed.
     fifteen
    This solution has the advantage that it does not require power and is highly reliable. On the other hand, the weight of the car increases considerably, so it is not preferred.

    The most preferred solution, which is part of the invention as an independent element, comprises an active stabilizer (4), which starts from a detector (7) of the inclination of the platform (2) or frame, both lateral and longitudinal to the car, using accelerometers or automatic levels (gravity or magnetic compensators). This detector (7) can be adjustable to define the inclination to be stabilized, or it can be programmed by means of a control on the handlebar of the car.
     25
    The signal from the corresponding detector (7) is transferred to a microcontroller (8) that acts on a motor (9), preferably step by step, that performs the movement of the platform (2) or frame so that it returns to the predefined position, normally horizontal. This movement will generally be through an arm (10).
     30
    Preferably, the signal of the detector (7) or detectors passes through a filter to eliminate interference and obviate the values that are not desired to be taken into account. For example, it may not act unless an angle of X degrees (predefined or programmable) is exceeded for a time of N seconds. Then, by means of a control law, it is indicated which movement the motor (9) must make (steps, angle, revolutions, etc.) and in which direction to correct the position of the platform (2) or frame.

    The motor (9) can act on the arm (10) in several ways (connecting rod-crank, rack-pinion, linear motor, ...). The preferred form is the crank rod mechanism shown in Figure 3, formed by a rotor (11), which in this case is operated by an endless screw (12), with an eccentric projection (13) that slides 5 with rotation along the longitudinal axis in a colossal hole (14) in the arm (10) acting as a connecting rod. For its part, the arm (10) has a fixed end resting on the frame (1) and the other end fixed to the platform (2) or base by means of a pair of sliding wheels (15) on a guide (16) integral to the platform (2) or base. These movable elements will be in a housing (17) from which one half has been removed in the exploded view 10 of Figure 3.

    These mechanisms will require a power supply, which may be at the bottom of the frame (1) to help the stability of the car.
     fifteen
    When the stabilizer (4) is active, it is possible to include a baby balancing function, so that the motor (9) is activated alternately in opposite directions, regardless of the signals of the detector (7).
