Description
TECHNICAL FIELD OF THE INVENTION

The present invention generally relates to construction forms and more specifically to an exercising device with combined stepping and twisting functions.

BACKGROUND OF THE INVENTION

In the prior art in which this invention appertains, exercising devices having combined stepping and twisting functions are well known. The trend of the advancement of the art is seemingly headed towards the development and improvement of different mechanisms that are used to provide the combined stepping and twisting functions. These prior art are discussed briefly hereunder.

U.S. Pat. No. 5,628,709 discloses an exerciser having stepping and twisting functions in which its pedal arms cause their respective tubular sleeves to rotate about a cylindrical body when pressure is applied on one of the pedal arms, thereby resulting in the combined stepping and twisting functions.

GB 2395443 discloses a stepping exerciser wherein the twisting function is caused by the forced rotation of a follower relative to a base which in turn causes foot supports to rotate with the follower giving the user a twisting motion while conducting stepping exercises.

In US2005020412, an exerciser for step and twist includes a base and a swing device secured to the base. The swing device has a pair of pedals which are secured to a post and linked by a cable to a roller. Two ends of the cable are connected with extensions protruding from the pedals. A spindle of the roller is provided with a gear to mesh with the teeth of a disc on the base. When stepping on the pedals, the cable links the roller to spin, whereas the gear rolls along the teeth of the disc to move the pedals from left to right or vice versa, thus, the exerciser provides a stepping and twisting effects to users.

The foregoing exercisers do not provide a selection and locking mechanism to allow the user to choose a preferred function, i.e. stepping or twisting or both combined. Other similar exercisers with combined step and twist functions are provided in GB 2341332, FR2868958, U.S. Pat. No. 5,906,562, US2004097337, and US2006035756.

While the foregoing exercisers in the prior art do not have function-selecting means, there are some that teach combined step and twist exercisers with locking and/or selection means which allow the user to select preferred function such the following:

In U.S. Pat. No. 5,453,065, a combined step and twist exerciser is provided that has a lower stationary support frame with an upright shaft fixed thereto. It has a stepper mechanism which has a base body mounted rotatably on the shaft and having a front portion and a rear portion, a pair of spaced pedal arms, each of which having a front end pivoted to the front portion and a rear end portion extending from the front end toward the rear portion, and a pair of resistance cylinders, each of which interconnecting the rear end portion of a respective one of pedal arms and the base body. A horizontal plate member is mounted to the shaft above the base body and has two opposite spaced rear portions on two sides of the shaft. A locking unit is provided to lock releasably the plate member relative to the stationary support frame.

U.S. Pat. No. 5,284,461 and U.S. Pat. No. 5,527,253 disclose and teach step and/or twist exercisers which may be selectively inactivated so that only one or both of the functions could be used.

Careful analysis of the aforementioned prior art reveals that all their actuating mechanisms that allow their functionalities to operate are relatively complex comprising of multiple parts or elements. The functions they are capable of performing are normally results of and/or inherent to the separate interacting elements/mechanisms or assemblage of parts so designed/configured to do such functions, hence, the more functionalities desired, the more parts or elements needed or required to comprise and operate such functionalities of the prior art exercisers. It is also noteworthy that a separate element in a form of hydraulic or pneumatic device is normally adopted by the prior art to provide resistance to the stepper unit or pedal, a feature that is common to most, if not all, of them. Furthermore, selection of functions, i.e. stepping, twisting or combination of both, is not that ergonomic or user-friendly to the users as it is dictated by decentralized separate mechanisms performing such functions.

SUMMARY OF THE INVENTION

The invention seeks to overcome the drawbacks and shortcomings of the prior art by providing an exercising device with combined stepping and twisting functions that is relatively much simpler than those of the prior art in terms of the structural features and number of elements/parts it comprises. It has a centralized assemblage (C) of elements or mechanisms that facilitates multiple functions through a simple selective and pre-determined in operation or immobilization of certain part(s) or element(s) or mechanism(s) thereof comprising the assemblage. Thus, in operation, the invention is very ergonomic, convenient and user-friendly to use and operate due to its easy and practical way of selecting functions, i.e. stepping, twisting or combination of both, that is also practically centralized as inherent result of the centralized assemblage (C). In addition to that, the present invention has the mechanism thereof capable of performing functionalities, which are separately performed by respective mechanisms or elements in the prior art, such as the application of a stepper resistance.

The aforementioned capabilities and functionalities of the invention are results of the characterizing features and elements thereof disclosed and taught herein. The invention preferably embodying an exercising device (10,10 a), while comprising some of the old elements in the prior art in combination with the centralized assemblage (C) thereof, is characterized by a stepper mounting means (12) and engaging rotatable mechanism (14), preferably serving also as a stepper resistance-providing mechanism, that are lockably and horizontally rotatable relative to each other and base member (11) at a common axis of rotation (17) located proximate the central section of the device (10,10 a), such that a stepping function is activated solely when the mounting means (12) is made non-rotatable relative to the base member (11) while the mechanism (14) being in a rotatable state relative to the mounting means (12); a twisting function is activated solely when the mechanism (14) is made non-rotatable relative to the mounting means (12) while the mounting means (12) being in a rotatable state relative to the base member (11); and combined stepping and twisting functions are activated simultaneously when the mechanism (14) is made non-rotatable relative to the base member (11) while the mounting means (12) being in a rotatable state relative to the base member (11) and the mechanism (14).

The primary object therefore of the present invention is to provide an exercising device with combined stepping and twisting functions that is capable of performing more functions or functionalities such as stepping, twisting and combination of both, including provision of stepper resistance, with less elements or mechanisms, thus, very efficient, practical and economical to use, manufacture and commercialize.

Another object of the present invention is to provide an exercising device with combined stepping and twisting functions that has very ergonomic and user-friendly operating features, especially the function-selection feature, that are centralized in one area.

Still another object thereof is to provide an exercising device with combined stepping and twisting functions that is does not only provide an efficient, effective and practical way of performing an exercise, but also an exerciser that is very easy to use, operate and store or keep after usage.

DETAILED DESCRIPTION OF THE INVENTION

Before describing the preferred embodiments of the invention in detail, it is to be understood that the phraseologies and terminologies employed herein are for purposes of description and should not be regarded as limiting.

Referring now to the drawings in which like reference numerals designate the same components or elements all throughout the succeeding description, there is shown in FIGS. 1 and 5 an exercising device with combined stepping and twisting functions generally designated by reference numerals 10 and 10 a, respectively, comprising a base member 11, a stepper mounting means 12 mounted on the base member 11, and a stepper assembly 13 pivotably and rotatably secured with respect to the mounting means 12 and the base member 11 in a manner that the stepper assembly 13 is capable of performing, simultaneously or one at a time, stepping and twisting functions. The stepper assembly 13 performs such functions through an engaging rotatable mechanism 14 into which the stepper assembly 13 is movably engaged through a linkage means 15. A selecting means 16 for selectively activating or deactivating such functions is provided to the device 10. With the combination of elements just described, the present invention is characterized in that the stepper mounting means 12 and engaging rotatable mechanism 14 are lockably and horizontally rotatable with respect to each other and the base member 11 at a common axis of rotation 17 located proximate the central section of the device 10,10 a. With such structural set-up of the invention, the following functionalities are capable of being performed thereby: a stepping function of the device 10,10 a is activated solely when the mounting means 12 is made non-rotatable relative to the base member 11 while the mechanism 14 being in a rotatable state relative to the mounting means 12; a twisting function is activated solely when the mechanism 14 is made non-rotatable relative to the mounting means 12 while the mounting means 12 being in a rotatable state relative to the base member 11; and combined stepping and twisting functions are activated simultaneously when the mechanism 14 is made non-rotatable relative to the base member 11 while the mounting means 12 being in a rotatable state relative to the base member 11 and the mechanism 14.

The characterizing elements and features of the invention as described above generally define a centralized assemblage of elements or mechanisms “C” that facilitates the above-identified multiple functions through a simple selective and pre-determined in operation or immobilization of certain part(s) or element(s) or mechanism(s) thereof, i.e. rotational mechanism 14 and mounting means 12, essentially comprising the assemblage “C”. Thus, in operation, the invention is very ergonomic, convenient and user-friendly to use and operate due to its easy and practical way of selecting functions, i.e. stepping, twisting or combination of both, that is also practically centralized as inherent result of the centralized assemblage “C”.

The rotatable mechanism 14 is preferably in a form of a pair of complementing lower and upper disk members 18 a and 18 b, respectively. The lower disk member 18 a is fixedly secured to the mounting means 12 while the upper disk member 18 b that is rotatably engaged with the lower disk member 18 a is rotatably mounted on the base member 11 through an upstanding axle 19 provided thereon along the common axis of rotation 17. For the preferred embodiment of the invention as shown in the illustrative example depicted in the drawings, the rotatable mechanism 14 functions also as a stepper load resistance that translates into a resistive force applied to the stepper assembly 13. To effectively function as a varying resistance to the stepping and rotating movements of the stepper assembly 13, the lower and upper disk members 18 a and 18 b are preferably in a form of friction disks comprising of female disk and male disk members 18 a′ and 18 b′, respectively. The male disk member 18 b′ having peripheral ridge 19 b that is frictionally engaged with respective peripheral channel 19 a provided on the female member 18 a′, the engagement of both members 18 b′ and 18 a′ being compressively and adjustably secured by a tightening means 20 engaged with the axle 19. The tightening means 20 has a preferably ergonomic handle 21 suitably designed to facilitate easy manual gripping and twisting action when in use. This capability of the mechanism 14 itself to function as a stepper resistance is separately performed by another mechanism or element of the prior art exerciser that is usually in form of an hydraulic or pneumatic mechanism or device (not shown).

The locking means 16 allows or disallows relative rotational movements among the essential elements, i.e. base member 11, mounting means 12 and rotational mechanism 14. Preferably, this locking means 16 is in a form of a releasable knob-type lock 16 a. In the preferred embodiments of the invention, a pair of the locks 16 a is being provided to the mechanism 14 wherein one lock 16 b is releasably lockable to the mounting means 12, and the other lock 16 c being releasably lockable to the base member 11 that is also provided with another same type of lock 16 d being releasably lockable to the mounting means 12. The knob-type lock 16 a is preferably of a type that comprises a spring-biased latch member 22 slidably mounted in a sleeve 23 fixedly secured on the mechanism 14 and base member 11. The latch member 22 is lockably engageable with a corresponding catch 24 provided to the mounting means 12 and base member 11. In usage, when being released from the spring-biased engagement thereof with the sleeve 23 in an unlocked normal position, the latch member 22 is brought to lockably engage with the corresponding catch 24.

In the preferred embodiment of the knob-type lock 16 a shown in FIG. 4, the latch member 22 is preferably a generally tubular member 22 a that is spirally and concentrically slidable longitudinally within the sleeve 23 that is preferably in a form of a generally annular sleeve 23 a defining an inner elongated member 25 whose top end portion is being provided with a pre-determined means 26 for indicating the function of the device selected during use. This means 26 is preferably in forms of label, tag, sticker, engraving, light, or any desired indicators. When the member 22 a is in an upwardly lifted, biased normal unlocked position, the member 25 is concealed downwardly within the member 22 a. But when the member 22 a is in a downwardly released and locked position, the member 25 shows up with the means 26 thereof being exposed at the top portion of the member 22 a, indicating the particular associated function of the device 10,10 a that is at work as selected by a user.

In the preferred embodiments of the invention, the rotatable mountings of the rotatable mechanism 14 and mounting means 12 into the axle 19 adopt the use of bearing members 26. Furthermore, the base member 11 is provided with a stopper 27 that limits the rotational displacement of the mounting means 12. Their stepper assemblies 13 respectively comprise of a pair of pedal arms 28 with respective pedals 29, the pedal arms 28 being pivotably mounted, at the sleeved front end portions thereof 28 a, to corresponding opposite side branching shaft members 30 provided upwardly on an upstanding frontal post member 31 of the mounting means 12, the sleeved end portion 28 a being connected to the mechanism 14 through the linkage means 15 which is in a form of two-part linkage member 15 a. These features are clearly shown in FIGS. 5 and 6 for the preferred embodiment of the invention in its basic form.

Preferably, the invention embodying the preferred devices 10 and 10 a has the base member 11 thereof adopting any stable structural platforms such as I-beam type 11 a with front and rear anchor members, radial type 11 b with radial anchor members, and any polygonal type with variations of anchor member arrangements (not shown). In addition, there is likewise provided a means 32 mounted on the base member 11 or the mounting means 12. This hand-exercising means 32 is preferably in forms of a pair of handy stretchable cords 33, a twistable upstanding pole member 34 with oppositely branching horizontal handles 35, or a Nordic stick 36 conveniently mounted and positioned rearwardly of the device 10,10 a.

Before defining the scope of the following claims, it is to be understood that the invention is not limited in its applications to the details of the embodied devices in the preceding description or illustrated in the drawings. It is to be noted that the invention is capable of other embodiments and limitless applications not disclosed herein, and of being practiced and carried out in various ways falling within the teaching and scope of the following claims.
