    [0004] Technical area
    [0005] The present invention relates to a walker with a switch to convert it between two modes, exercise walker and regular walker. Background
    [0006] Within the prior art there are various embodiments of general exercise walkers, which include walkers with handles arranged on some arms, configured to transfer crank movements from the rollers' wheels to said handles.
    [0007] A problem of general exercise walkers is the increase in the cost of their production. From a financial point of view, it can be difficult to motivate the purchase of a walker with this characteristic, especially if a potential user already has a regular walker for daily use, or if he needs one. Those who acquire a general walker, in addition to a walker for daily use, must also deal with an inherent problem, keep two walkers, something that not all potential users can face due to a limited space of storage.
    [0008] Thus, there is a need for an invention that solves both the economic problem and the problem of the storage space required to store both types of walkers.
    [0009] Summary of the invention
    [0010] The object of the present invention is to provide an improved solution that reduces the aforementioned drawbacks of the current solutions of general exercise walkers, also known as exercise walkers. This is achieved by obtaining a walker comprising a connection that can be switched between two different modes, a connected mode and a disconnected mode, in which, in the connected mode, the walker is configured for general exercise, that is, a walker exercise with arms that alternately move forward and backward when the rollator wheels roll, and in which, in disconnected mode, the walker is set up as a regular walker with fixed arms.
    [0011] According to a first aspect of the invention, there is provided a walker comprising at least one wheel arranged on a wheel rod, rotatable about a rotation axis, wherein said at least one wheel can rotate freely with respect to the axis of the wheel, also around the same axis of rotation. The walker can be equipped with multiple wheels, one of which can be arranged on the same axle on which said at least one wheel is arranged, but at a distance from said at least one wheel. Additionally, the walker may be equipped with one or more support wheels to help the walker stand upright on its own.
    [0012] Additionally, the walker can be equipped with arms configured to provide support to a possible user. Additionally, the arms may be equipped with handles to provide a better grip on the walker. The handles can also be configured to offer better walker control, and be equipped with hand brakes that counteract the bearing of at least one of the walker's wheels.
    [0013] Additionally, the walker can comprise two arms configured to transfer a crank movement from the wheel rod, around its axis of rotation, through the arm joints to alternately move forward and backward around the axis of rotation. . In this way, a / possible user holding the walker's handhold may be forced to move their arms forward and backward when the wheel rod is rotated, possibly due to the rolling of the wheels when the walker is rolling on. any direction, either forward or backward.
    [0014] Additionally, the walker comprises a walker connection that can be adjusted between a connected mode and a disconnected mode, the wheels being able to rotate freely with respect to the wheel rod around the axis of rotation when the walker connection is in disconnected mode and the arms can be locked to a desired position, preferably parallel, by fixing the disk in a control when the walker connection is in disconnected mode, and the arms can be locked in a desired position, preferably parallel, by fixing the disk of a control when the Walker connection is in disengaged mode. Additionally, a wheel disc may be arranged on the wheel rod, and may rotate freely relative to the wheel rod, so that the guide fixes the movement of the wheel disk with the movement of the wheel; where, in the connected mode, the walker connection fixes a wheel to the wheel rod so that the wheel follows the rotation of the wheel rod around the axis of rotation, through a coupling clutch disc with a pin, which engages the wheel disc by operating the clutch disc, by means of a control rod, to a position where the pin locks the wheel disc with the clutch disc through a hole in the wheel disk. The walker connection can be returned to its disconnected mode through a cam roller.
    [0015] One of the advantages of the invention disclosed is that the walker can be switched between two modes, so that the same walker can function as an exercise walker, with alternately rotating arms, and as a regular walker, with fixed arms. This means that a user does not have to choose between two different walkers with different functional aspects, but can choose a walker that meets the functional aspects of both walkers. In this way, the disclosed invention can solve the problem of cost.
    [0016] Another advantage of the invention disclosed is that it can take up less space than a regular walker and an exercise walker would normally occupy. In this way, the disclosed invention can solve the problem of limited storage space.
    [0017] Another advantage of the invention disclosed is that, even in the connected mode of the walker connection, the walker can be turned to its position without affecting the alternative movement of the arms. This is possible because the invention can be carried out by fixing only one of the wheels with the wheel rod. Even so, another wheel located on the same wheel rod can rotate freely, so that the walker can be turned to its position around the fixed position of the wheel, so that the walker can be directed in a new direction. Thus, with the invention disclosed it is not necessary to switch between modes when it is necessary to swing the walker.
