  • the majority of treadmills are provided with a shock absorbing system which is able to absorb the micro-injuries which running can generate, especially when performed on hard ground whilst wearing unsuitable footwear.
  • the prior art treadmills also comprise mechanisms for tilting the base, generally driven by an actuator, which are configured to vary the slope of the belt, by tilting the walking surface relative to the plane defined by the floor.
  • the prior art treadmills usually comprise one or more uprights coupled to the frame and elongate in a substantially vertical direction to support a control panel which can be reached by the user in an upright position.
  • the control panel may have keys which can be reached by the user during use of the exercise machine. Typically, the keys allow the immediate control of the exercise parameters (for example, speed and slope).

  • the control panel for the touch-screen display has a variable number of keys based on the quantity of data and the number of programs held by the specific exercise machine.
  • treadmills On the majority of treadmills it is possible to program exercises with aims of distance, time, heart rate and calories, at different speeds or slopes which can be set up by the user both during programming and during training. Moreover, the majority of treadmills comprise a memory with preset exercise programs. Many models offer the possibility of setting up new programs, with a number depending on the capacity of the memory and a software program configured to process data coming from one or more sensors with which the exercise machine is equipped. The adjustment of the speed and slope allows the effort exerted to be modulated, adapting it to the individual capabilities and the progress achieved thanks to the exercising.

  • the user can rest on the handles and move the feet to the side footrests.
  • the role played by the handles may be fundamental for the safety of the user.
  • the shape of the handles is designed for the safety of the user without obstructing movements.

  • the coupling is such as to make the handles movable, by rotation, between an extended position, where they can be easily reached by the user, and a withdrawn position in which the space available to the user during use of the exercise machine is greater.
  • the prior art treadmills have different features depending on the environment for which they have been designed. More specifically, for home applications in which the space available may be limited, the prior art comprises reclosable (that is, foldable) treadmills, designed to adopt a configuration which reduces as much as possible the overall dimensions (that is, the folded configuration) when the exercise machine is not used.
  • the frame of the reclosable treadmills comprises an opening and/or closing mechanism, which allows the plane of the belt to be moved, typically by rotation, towards the plane in which the directions of extension of the uprights lie.
  • Patent document U.S. Pat. No. 8,182,399 shows a reclosable treadmill wherein the handles are pivoted to the frame to rotate in such a way as to adopt an extended position during use, and a withdrawn position wherein, once the treadmill is reclosed, the direction along which they extend is substantially parallel to the plane defined by the treadable surface.
  • Patent document US20130237381 shows a reclosable treadmill wherein the handles have an elongate shape in one direction and are coupled rigidly to the control panel.
  • the control panel is coupled to the uprights in such a way as to rotate during the closing of the treadmill.

Moreover, the reduction of the overall dimensions by rotating the handle is applicable only to the handles having a shape elongate in a direction.
  • the curved handles which are preferably since they improve the ergonomics of the exercise machine and the safety for the user, are typically coupled rigidly to the frame, through an attaching system (for example, by screws) which requires the intervention of a skilled technician to carry out the maintenance or the replacement of the component.

  • the handles are connected to the uprights in a removable fashion by rapid lock release elements which can be operated manually, so that coupling or uncoupling of the handles from the uprights can be performed manually, without the aid of any tool, and in a particularly rapid and easy manner.
  • the treadmill is configured so that it can rest on a horizontal supporting surface, for example a floor.
  • the uprights are inclined respect to this horizontal plane, for example they are vertical or substantially vertically (but they might also have different inclinations); in any case, the handles are elongate along respective longitudinal directions.
  • the treadmill is foldable, that is, it comprises parts movably connected to each other (for example by hinges) for being moved between an open position, wherein the treadmill is designed to perform its fitness exercise functions, and a closed position, folded, wherein the treadmill occupies a particularly reduced size, so as to be packed, stored or simply placed in an area of a home or of a gym.
  • the uprights rotate relative to a portion of the frame designed to support the belt.
  • the handles have a U-shaped grip portion. This favours the safety and ease of use by the user.
  • the treadmill comprises a shape coupling between handle and upright.
  • the treadmill comprises a lock/release mechanism movable between (at least) two configurations, one for locking, wherein the handle is fixed stably to the respective upright, and one for releasing, wherein the handle may be manually removed from the upright.
  • the upright has a shaped hollow seat to house a corresponding projecting portion of the handle.
  • the male and female role is exchanged between handle and upright, in the shape coupling (this circumstance also applies in consideration of the further features described below regarding the shape coupling).
  • this shape coupling defines a interlocking.
  • the shape coupling is extended along a straight portion of the upright; the shape coupling occupies an area of the upright and a corresponding area of the handle elongated along a longitudinal axis (the axis in which the upright is oriented).
  • the shape coupling preferably comprises a taper coupling by interference, made, for example, by a wedge which can be inserted in a seat.
  • the taper coupling defines a transversal axis of moving towards (that is, insertion) and away (that is, extraction) of the wedge from the respective seat, that is, of the handle from the upright.
  • This transversal direction is substantially parallel to the sliding direction of the belt of the treadmill, when it is parallel to the horizontal plane for supporting the treadmill.
  • the handle has a wedge which can be inserted in a seat defined by the upright.
  • the wedge has tapered lateral faces; preferably, the tapered lateral faces of the wedge define a plurality of protrusions alternated with grooves, elongated in the transversal direction of the wedge towards and away from the respective seat.
  • the purpose of the tapered coupling is to eliminate the clearances of the handle relative to the upright in a direction perpendicular to the longitudinal direction of the upright and relative to the transversal direction of inserting and removing.
  • the shape coupling comprises a slot-in coupling between a tooth and a corresponding slot.
  • the tooth is integral with the handle and defined by the upright.
  • the purpose of the slot-in coupling by inserting teeth in the corresponding slot, is to generate a robust and safe constraint against accidental movement of the handle along the transversal direction, that is, in the direction of extraction from the upright.
  • the slot constitutes a hole oriented along the longitudinal axis; the tooth protrudes downwards from a ledge defined by the handle and, when the handle is coupled to the upright, protrudes longitudinally downwards and engages the slot.
  • the shape coupling comprises (a guide defining) a contact surface defining a constraint to a longitudinal movement of the handle relative to the upright.
  • the contact surface (of the guide) is integral with the upright and acting in conjunction with a corresponding surface defined by the handle.
  • the contact surface faces downwards, that is, towards the supporting surface of the treadmill; preferably, the contact surface is inclined relative to the supporting surface of the treadmill about an axis perpendicular to the longitudinal direction (along which the upright is elongate) and to the transversal direction (for inserting and removing the handle of the upright).
  • the purpose of the contact surface is to eliminate the clearances of the handle relative to the upright in the longitudinal direction in which the upright extends.
  • the upright comprises a reference profile, comprising at least one rectilinear portion defining a first axis of rotation about which the handle is rotatable to produce the shape coupling.
  • the rectilinear portion is formed by the upright at an upper end of the shape coupling, distal from a treadmill supporting surface.
  • the rectilinear portion is oriented along an axis perpendicular to the longitudinal direction (along which the upright is elongate) and to the transversal direction (for inserting and removing the handle of the upright).
  • This rectilinear portion defines a contact zone for a corresponding portion of the handle, shaped, for example, in the form of a step.
  • this rectilinear portion is to define with precision and uniquely an initial position wherein the handle must be located relative to the upright, for then coupling the handle to the upright.
  • the initial position is a position wherein a predetermined contact surface of the handle (at an upper end of the upright) is in contact with the rectilinear portion of the upright, and wherein the opposite end of the handle is offset from the upright; so the handle is located in a position rotated relative to a position for coupling to the upright, rotated about the axis defined by the rectilinear portion of the upright.
  • the lock/release mechanism is configured to adopt two stable equilibrium positions and to switch from one to the other by means of snap-in connection.
  • the lock/release mechanism comprises a hook connected to the handle and a pin connected to the frame.
  • the hook is connected to a movable lever, accessible to the user.
  • the lever is pivoted on the handle and rotates about a second axis of rotation to move the hook towards or away from the pin.
  • the lock and release mechanism comprises a first elastic element operating in conjunction with the lever and the hook to keep them in a predetermined position relative to one another in the absence of external forces.
  • the lock/release mechanism also comprises a second elastic element configured to oppose the rotation of the lever in a locking direction, until reaching a predetermined angular position of the lever, beyond which the elastic element promotes the rotation of the lever in the releasing direction.
  • the second elastic element is configured to define at least one angular position of stable equilibrium for the lever.
  • the second elastic element is configured to oppose the rotation of the lever in a locking direction until a predetermined angular position of the lever has been reached, beyond which the elastic element promotes the rotation of the lever in the releasing direction.
  • the pin of the lock/release mechanism is connected to the upright in a lower area of the shape coupling, proximal to a supporting surface of the treadmill; this increases the robustness and the safety of the handle, since the force applied by the user on the handle directed downwards does not bear directly on the lock release mechanism but only on the contact surface.
  • This invention also provides a method for assembling a treadmill, comprising a connection of at least one handle to a corresponding upright of a frame of the treadmill.
  • this connection of the handle (that is, of the handles, because preferably there are two or more) to the upright is removable.
  • this connection of the handle to the upright comprises the following steps:
  • the fastening comprises a step for the mutual preparatory positioning of the handle relative to the upright.
  • the method preferably comprises the following steps, prior to the activation of the lock mechanism:
  • the treadmill is of the foldable or re-foldable type and the assembly method comprises a step of rotating the upright relative to a belt, to bring the treadmill to an open working position, from a closed position folded.
  • the handle distal from the supporting surface of the treadmill, which rests on the reference profile of the upright.
  • the rotation of the handle is carried out about an axis perpendicular to the longitudinal direction of extension of the upright and to a direction of sliding of the belt of the treadmill, when the belt is positioned horizontally, parallel to the supporting surface of the treadmill.
  • this rotation also comprises, in particular in a relative final part, a pushing of the handle against the upright along a transversal direction, parallel to the sliding direction of the belt of the treadmill, when the belt is positioned horizontally, parallel to the supporting surface of the treadmill; this is to make a coupling with interference between a portion of the handle and a corresponding portion of the upright.
  • this description also concerns an exercise machine generally speaking having a frame equipped with uprights and handles designed to be fixed to the uprights, wherein the handles are fastened in such a way as to be removable manually from the uprights, according to one or more of the features described in this invention.

  • this invention allows a handle to be fitted to and removed from a treadmill (and in more general terms, to and from an upright of an exercise machine) quickly and easily, guaranteeing at the same time the robustness of the handle fitted.
  • the solution according to this invention simplifies and speeds up the assembly operation of the handle, even allowing an unskilled person to quickly fit the handle; this is particularly useful for exercise machines intended for use at home; moreover, this facilitates a replacement of handles over time (because they are worn or for reasons of appearance).
  • the solution according to this invention is particularly attractive in appearance, since screws or other fastening means cannot be seen from the outside, except for the lock release mechanism; in effect, the shape coupling, when the handle is fixed to the upright, is completely enclosed in a space formed inside the upright and the handle.

  • the lock/release mechanism 16 comprises a connecting plate 17 , to connect the lock/release mechanism 16 to the handle 7 .
  • the lock/release 16 mechanism comprises a lever 18 coupled to the connecting plate 17 .
  • the lever 18 is coupled to the plate 17 so as to rotate about a second axis of rotation B; the second axis of rotation B is oriented in such a way that, when the handle 7 is coupled to the upright 3 , the second axis of rotation B is parallel to the supporting surface of the treadmill 1 and perpendicular to the movement direction of the belt 4 .
  • the lock/release mechanism 16 comprises a hook 19 having a first and a second end.
  • the first end of the hook 19 is coupled to the lever 18 to define a rotation constraint.
  • the hook is rotatably coupled to the lever 18 so that it rotates about a third axis of rotation C, parallel (substantially) to the second axis of rotation B.
  • the second end of the hook 19 is configured for coupling with a pin 20 of the upright 3 , positioned in the shaped hollow seat 8 .
  • the second end of the hook 19 forms a slot.
  • the pin 20 has a shaped end, defining a portion inclined towards the direction of movement of the hook 19 , so as to form an undercut for locking the hook 19 , when the hook 19 is connected to the pin 20 .
  • the lock release mechanism 16 also comprises a first elastic element 21 (for balancing).
  • the first elastic element 21 is interposed between the lever 18 and the hook 19 .
  • the first elastic element 21 is preferably configured to define a predetermined reciprocal position relative of the hook 19 with respect to the lever 18 , in the absence of external forces.
  • the first elastic element 21 is a helical spring.
  • the lock/release mechanism 16 also comprises a second elastic element 22 ; preferably, the second elastic element 22 is connected to the handle 7 .
  • the second elastic element 22 is a leaf spring.
  • the second elastic element 22 is configured to interact with a surface of the lever 18 defining a cam profile 18 a .
  • the lever 18 can rotate in a first direction (that is, a release direction) and in a second direction (that is, a lock direction).
  • the second elastic element 22 does not interact with the lever 18 until reaching a first predetermined angular position (illustrated in FIG. 12 ), wherein the cam profile 18 a enters into contact with the second elastic element 22 .
  • the second elastic element 22 generates a force which opposes the rotation of the lever 18 in the release direction, until reaching a predetermined angular position of the lever 18 (illustrated in FIG. 13 ). A further rotation of the lever 18 (facilitated by the second elastic element 22 ), beyond that angular position, allows the lever 18 to reach a second position of its stable equilibrium ( FIG. 14 ).
  • the user To uncouple the hook 19 from the pin 20 , the user must therefore overcome the resistance of the second elastic element 22 , rotating further the lever 18 in the release direction.
  • the rotation of the lever 18 causes the movement, by roto-translation, of the second end of the hook 19 towards the upright 3 .
  • the roto-translation occurs thanks to the first elastic element 21 , which allows the relative position between the hook 19 and the lever 18 to be maintained, allowing the second end of the hook 19 to move in the direction away from the supporting surface of the treadmill 1 , and hence uncouple the hook 19 from the pin 20 .
  • the second elastic element 22 interacts with the lever 18 obstructing the rotation, until reaching a predetermined angular position, beyond which the second elastic element 22 interacts with the profile of the cam surface 18 a , favouring the rotation in the lock direction.
