- number 1 indicates, in its entirety, a gymnastic machine 1 comprising a frame 10, a load group 20 carried by the frame 10, at least a gymnastic implement 30 connected to the load group 20 through at least a transmission member 40 to exchange energy with the load group 20.
- This transmission member 40 comprises at least a box-shaped lever 42 that is very light and has considerable torsional rigidity, as it will be apparent from the description below; each lever 42 is provided with a coupling device 45 connected to the frame 10 by means of a pivot pin 60.
- Each implement 30 presents maximum transverse extension equal to D, which in the case of the implement 30 being obtained from a cylindrical bar, would coincide with the respective diameter.
- the machine illustrated in figure 1 is of the free weight type, but this choice does not detract from the general nature of the teachings provided, which can be effectively applied also to machines in which the load is of the hydraulic, electromagnetic type, or in which the gravitational load comprises a weight stack movable along a rectilinear guide, which can be grouped together through an elongated body that passes through them transversely and is connected to the respective levers by means of a flexible member, generally a cable made of textile material.

- the cross-section of the elbow 48 is given by the combination of the cross-sections of the segments 468 mutually connected, and thus greater than each of the two considered individually to stiffen the lever 42 in the point of maximum concentration of the load.
- each lever 42 presents a cross-section that decreases in height from the pin 60 to the implement 30 neglecting the portion of the elbow 48 also due to the fact that in the case of levers of weight stack machines this portion will be absent.

- the maximum value of the transverse cross-section S would be located in correspondence of the pin 60, whilst in the second case the maximum value of the transverse cross-section S would be located in correspondence of the elbow 48, and thus of the elongated member 49.

Description
- The present invention relates to a gymnastic machine provided with at least a lever. In particular, the present invention relates to a gymnastic machine provided with at least a lever usable to actuate a load group. In more detail, the present invention relates to a gymnastic machine provided with at least a lever usable to actuate a load group and to a method for producing this lever.
- In the field of gymnastic equipment, it is known to manufacture gymnastic machines provided with levers pivoted to a frame supporting a load group, normally of the gravitational, hydraulic or electromagnetic type. These levers are of the substantially box-shaped type in order to optimise the ratio between the mass and the mechanical resistance and to minimise the cost thereof. Normally, these levers are produced by cutting bars which have a constant and generally rectangular cross-section to be more easily machinable. Again in order to optimise the ratio between the mass and the mechanical resistance and to minimise the cost thereof, the greater dimension of the cross-section of the bars is parallel to the plane in which the lever is actuated in consideration of that the transverse load is substantially negligible and the lever is rigid enough to absorb it without damage even when the width is substantially half the depth. Similar cases occur in the majority of gymnastic machines with gravitational load and weight stack movable along a rectilinear guide, which can be grouped together through an elongated body which passes through them transversely and is connected to the levers by means of a flexible member, generally a cable made of textile material.
- Furthermore, when the load group comprises free weights which must be carried laterally by the same levers through adequate pins, it is well understood that these levers are subject not only to shear stress but also to torque, just as the coupling pins for coupling the levers to the frame. Therefore, in these cases, the choice is generally made to use levers which present rectangular cross-sections tending more toward a square shape and/or to strengthen the lever in correspondence of the coupling section thereof extending the pin and dividing the hub for connection to the frame into a fork. In addition to this, by choosing to use a lever of reduced transverse dimensions, thus subjecting the portions that couple the pins to the frame to considerable shear stress, a safety member must be inserted for supporting the pin in the case of breakage thereof or of the respective support.
- Furthermore, it should be noted that free weight machines are generally used by the most competent body building enthusiasts, who wish to experience feelings as similar as possible to the use of free weights held directly or carried by dumbbells or barbells; this obliges the manufacturers of levers to balance them so as to make them substantially neutral when no load is applied thereon. Therefore, it is also known that the use of levers of considerable cross-section obliges manufacturers to strengthen the frame and thus the machine in its entirety, and also to load the levers before having added the free weights for execution of an exercise. This contributes toward placing manufacturers in the position of choosing whether to strengthen the resistant cross-sections or to complicate the shape of the levers with the result of compromising the aesthetic appearance, as already described above.
- In view of the above description, the problem of having available a gymnastic machine in which the interaction between the implement and the corresponding load group is carried out by means of levers of simple shape, light, carried by the frame through a single hub and, simultaneously, capable of withstanding the exchange of high energy values in the unit of time and of high torsional stresses with the respective pin for connection to the frame is currently unsolved. The solution of this problem represents an interesting challenge for the applicant in order to simplify the structure of the gymnastic machines, to lighten the mass of one or their most characterising components, due to the fact that it carries the interface through which the user interacts with the load, and to make them safer without the need to resort to the use of additional members that would compromise the style and outer appearance.
- In view of the situation described above, it would be desirable to have available a gymnastic machine which, in addition to enabling to limit and possibly to overcome the typical drawbacks of the art illustrated above, could define a new standard for the gymnastic machines and, in particular, for free weight gymnastic machines.
- The present invention relates to a gymnastic machine provided with at least a lever. In particular, the present invention relates to a gymnastic machine provided with at least a lever usable to actuate a load group. More in particular, the present invention relates to a gymnastic machine provided with at least a lever usable to actuate a load group and to a method for producing this lever.
- The object of the present invention is to provide a gymnastic machine which allows the disadvantages described above to be solved, and which is suitable to satisfy a plurality of requirements that to date have still not been addressed, and therefore, suitable to represent a new and original source of economic interest and capable of modifying the current market of gymnastic machines.
- According to the present invention a gymnastic machine is provided, whose main characteristics are described in at least one of the appended claims.
- Furthermore, the present invention relates to a lever for this gymnastic machine, this lever being designed to contain the overall mass of the machine with the same resistance to torsional loads, to increase the safety degree of the machine in its entirety, and to simplify the structure thereof.
- According to the present invention a lever for this gymnastic machine is also provided, and the main characteristics of this lever are described in at least one of the appended claims.
- Further characteristics and advantages of the gymnastic machine according to the present invention will be more apparent from the description below, set forth with reference to the accompanying drawings, which illustrate at least one non-limiting example of embodiment, in which identical or corresponding parts of the device are identified by the same reference numbers. In particular:
-
figure 1 is a schematic perspective view of a gymnastic machine according to the present invention; -
figure 2 is a schematic perspective view in enlarged scale of a component extracted fromfigure 1 ; -
figure 3 is a side elevation view offigure 2 ; and -
figure 4 is an exploded view offigure 1 . - In
figure 1 ,number 1 indicates, in its entirety, agymnastic machine 1 comprising aframe 10, aload group 20 carried by theframe 10, at least agymnastic implement 30 connected to theload group 20 through at least a transmission member 40 to exchange energy with theload group 20. This transmission member 40 comprises at least a box-shaped lever 42 that is very light and has considerable torsional rigidity, as it will be apparent from the description below; eachlever 42 is provided with acoupling device 45 connected to theframe 10 by means of apivot pin 60. Eachimplement 30 presents maximum transverse extension equal to D, which in the case of theimplement 30 being obtained from a cylindrical bar, would coincide with the respective diameter. - As shall become readily apparent from the present description, the machine illustrated in
figure 1 is of the free weight type, but this choice does not detract from the general nature of the teachings provided, which can be effectively applied also to machines in which the load is of the hydraulic, electromagnetic type, or in which the gravitational load comprises a weight stack movable along a rectilinear guide, which can be grouped together through an elongated body that passes through them transversely and is connected to the respective levers by means of a flexible member, generally a cable made of textile material. - With particular reference to
figure 2 , eachlever 42 is longitudinally delimited by afirst end portion 43, so shaped as to house thepivot pin 60, and by a freesecond end portion 44, designed to house theimplement 30. Eachlever 42 is provided with at least onesegment 468 which is substantially rectilinear and presents a transverse cross-section S of given shape, whose width varies longitudinally so as to present a respective lateral profile PL substantially triangular in shape, and in particular of decreasing height according to a direction of travel which goes from thepivot pin 60 to theimplement 30. - It should be specified that the fact of having produced lateral profiles PL substantially triangular in shape does not decrease the resistance of the
levers 42 in the respectivesingle segments 468 thereof; in fact, the part of the material that has been eliminated would have not been submitted to any mechanical load; in other words the part of the material that has been eliminated would have not exerted any resistance against the load applied to the respective lever, but it would have just contributed exclusively toward increasing the overall weight of thelevers 42. - It should be noted that the
lever 42 shown infigures 1-3 comprises in particular twosegments 468 mutually connected by means of anelbow 48 which houses a cylindricalelongated member 49 in a respectivetransverse housing 466. Thiselongated member 49, which can also have a different cross-section, is designed to supportfree weights 80 and presents transverse cross-section of characteristic dimension L, which is in particular the measurement of its diameter. It should be noted that the cross-section of theelbow 48 is given by the combination of the cross-sections of thesegments 468 mutually connected, and thus greater than each of the two considered individually to stiffen thelever 42 in the point of maximum concentration of the load. - In any case, it must be considered that overall each
lever 42 presents a cross-section that decreases in height from thepin 60 to theimplement 30 neglecting the portion of theelbow 48 also due to the fact that in the case of levers of weight stack machines this portion will be absent. Therefore, both in the case in which eachlever 42 presents a profile PL that decreases in height from thepin 60 to theimplement 30, and in the case, shown infigures 2 and3 , in which the profile PL increases in height from thepin 60 to theelbow 48, to then subsequently decrease to theimplement 30, the transverse cross-section S of eachsegment 468 presents a maximum value according to a direction of travel that goes from thispivot pin 60 to thisimplement 30. In the first case, the maximum value of the transverse cross-section S would be located in correspondence of thepin 60, whilst in the second case the maximum value of the transverse cross-section S would be located in correspondence of theelbow 48, and thus of theelongated member 49. Therefore, again in the first case, thelever 42 is provided with one of therespective segments 468 which presents its own lateral profile PL of increasing height according to a direction of travel that goes from thepin 60 to theimplement 30. - With reference to the accompanying drawings, the transverse cross-section S of each
segment 468 presents polygonal shape, which is in particular substantially rectangular, and the width of the cross-section of eachsegment 468 longitudinally variable in a substantially homothetic manner; therefore, it presents longitudinally adjustable height. - Each
lever 42 presents transverse extension that can measure from one to four times a first transverse length D of theimplement 30 in order to exhibit high torsional rigidity. Furthermore, it has been found that it is possible to give high torsional rigidity also to alever 42 which presents transverse extension between 1.5 and 2 times the first transverse length D of theimplement 30 and a respective transverse cross-section S of substantially constant width. - With particular reference to
figure 4 , eachlever 42 comprises at least abase element 462 which presents longitudinally open and substantially C-shaped cross-section and which is closed by means of alongitudinal cover 464 coupled to therespective base element 462 by means of a welded connection. Eachcover 464 presents thickness between 0.5 and 10 mm in order to give lightness to thecorresponding segment 468. In actual fact, eachbase element 462 and eachrespective cover 464 are acceptable for the predetermined objects when they present thickness between 2 and 4 mm. - At this point it should be specified that each
base element 462 will present width between 25 and 150 mm, that this range will give better results if limited to a width between 80 and 130 mm, and that themachine 1 of the accompanying drawings is conceived topresent segments 468 whoserespective base element 462 presents width between 110 and 125 mm. - With reference to any one of
figures 2 and3 , thecoupling device 45 of eachlever 42 incorporates at least afirst bush 70 in correspondence of thefirst end portion 43 to house thepivot pin 60 in a freely rotatable manner. Thisfirst bush 70 presents transverse extension substantially identical to the extension of thefirst end portion 43 in order to minimise the torsional load on thepivot pin 60 produced by the free weights that are placed on theelongated body 49. - With particular reference to
figure 4 , eachlever 42, and in particular eachrespective segment 468, comprises at least abase element 462 which presents C-shaped cross-section and acover 464 coupled to therespective base element 462 by means of a welded connection. - Each
first bush 70 presents a respectiveexternal shell 72 and is rigidly connected to the respectivefirst end portion 43 by means of a welded connection on thisshell 72. Similarly, also eachsecond bush 74 presents a respectiveexternal shell 76 and is rigidly connected to the respectivesecond end portion 44 by means of a welded connection on thisshell 76. Furthermore, therespective implement 30 is shape housed in thebush 74 with a respectivecentral portion 32, which is rigidly connected to thesecond end portion 44 by means of a welded connection. Eachimplement 30 is longitudinally delimited by twoterminals central portion 32, so as to allow the involvement of distinct muscle regions for each manner of interfacing with theimplement 30. - Use of the
gymnastic machine 1 and of thecorresponding levers 42 is easily understood from the description above and requires no further explanations. Nonetheless, it may be advisable to specify that, in view of the above description, eachlever 42 allows to satisfy the expectations illustrated above for an improved capacity to withstand torsional stresses, and allows to stress in a limited manner thepin 60 and thus the respective connections to theframe 10, besides, naturally, allowing to give themachine 1 in its entirety greater aesthetic value. - Lastly, it is apparent that modifications and variants can be made to the
gymnastic machine 1 and to therespective levers 42 described and illustrated herein, without however departing from the protective scope of the present invention. - At this point, it is readily apparent that the method for constructing the
levers 42 described above will be different from the method used to produce the known levers of the prior art described above, and it is considered appropriate to describe it in its essential features. In particular, with particular reference tofigure 4 , the method for constructing alever 42 comprises a phase of providing eachbase element 462 with respective portions for connecting to an adjacentfurther base element 462 and, if necessary, and a phase of providing thetransverse housing 466 for theelongated member 49; eachbase element 462 shall be connected to therespective cover 464 by means of a welded connection on the edges. It is then possible to proceed to couple by welding thevarious segments 468, to couple thebushes second end portions external shells - Naturally, the phase of obtaining the
transverse housing 466 will be followed by a phase of connecting by welding theelongated member 49 to thetransverse housing 466.
