This application is the U.S. national phase entry under 35 U.S.C. § 371 of International Application No. PCT/EP2016/066436, filed on Jul. 11, 2016, which claims priority to European Patent Application No. 15176288.7, filed on Jul. 10, 2015, the entireties of which are herein incorporated by reference.
The current invention relates to a fitness system which has a frame element and different functional fitness elements to allow the creation of different fitness assemblies.
In the current specification, a fitness system should be understood as a collection of fitness elements which can be manufactured, sold and used as a system to provide different fitness activities. In the current specification the term “fitness” is used throughout. The term fitness when related to an element, a system, an arrangement etc should be understood as describing an element, a system, an arrangement, etc which provides or makes possible some form of physical training activity. This could be, for example, for training balance, strength, explosiveness, endurance, etc.
In the current specification, a functional fitness element should be understood as an element which comprises different mechanical components to provide an element on which a user can train one or more fitness exercises. In the current specification, a frame element is understood as a mechanical structure which is designed to be erected on a support surface in order to provide support to a functional fitness element mounted to the frame element. It should be mentioned that the frame element should be a clearly identifiable unique component of the system. There are many fitness structures in the prior art which are made up of different components which can be assembled into frames to support functional fitness elements. For example U.S. Pat. No. 1,126,082 discloses a system comprising a frame structure which is composed of a number of different elongated elements connected with corner pieces. The elongated elements are connected into a frame structure. However, there is no clearly identifiable standard frame element in the frame structure of U.S. Pat. No. 1,126,082. It is just one big structure. In the system according to the current invention, there is a clearly identifiable frame element which is connected with other elements in the system, but the unique frame elements are clearly identifiable. See for example
Other examples of structures comprising different elements joined together are for example disclosed in US 2015118670, WO 2009095283 and U.S. Pat. No. 4,278,250. In all these disclosed structures, different structural elements are provided to allow the creation of many different types of frame structures. This is different from the current invention, where a standard frame element is provided with different functional fitness elements connected thereto.
A fitness assembly should be understood as an assembly which comprises both a frame element and a functional fitness element mounted to the frame element. The term fitness machine is also sometimes used to refer to a fitness assembly, but the term fitness assembly should be understood broader than the term fitness machine.
The current invention also relates to a fitness assembly arrangement which comprises multiple fitness assemblies made up of different elements of the fitness system of the current invention.
According to the current specification, the term “fitness assembly arrangement” should be understood as a collection of different fitness assemblies erected together in a common location. For example, a group of fitness machines placed in a single room would be considered a fitness assembly arrangement. Likewise, a group of fitness assemblies erected outside in a park would be considered a fitness assembly arrangement. Instead of the term “fitness assembly arrangement” the term “arrangement of fitness assemblies” could also be used.
A related, but independent invention, is provided in the form of a weight lifting based functional fitness element comprising an elongated structure having a first end and a second end, and a weight element designed to be lifted directly by a user, said elongated structure being designed to be supported such that the first end is above the second end whereby the first end becomes an upper end and the second end becomes a lower end and such that an axis passing through the upper and lower ends of said elongated structure is arranged at an angle of less than 15 degrees, less than 10 degrees, or less than 5 degrees to the vertical, said weight element being displaceably fastened to the elongated structure such that the weight element is displaceable along the elongated structure.
According to the current specification the term “weight element” should be understood as an object which is to be lifted by a user as a form of exercise. The weight element has a certain weight which is suitable for the exercise being performed.
In the claims it is stated that the weight element is “designed to be lifted directly by a user”. This should be understood in that the user will be lifting the actual weight element directly without any further mechanisms between the user and the weight element. For example, a user will lift the weight element via a handle connected directly to the weight element. In contrast, in many prior art systems, the user lifts a weight element via a pulley mechanism of some sort via a cable.
In the claims it is stated that the weight element is displaceably fastened to an “elongated structure”. According to the current specification, the term “elongated structure” should be understood as a mechanical structure which controls the displacement of the weight element. In many prior art systems, a weight lifting barbell is arranged between two vertically arranged elongated elements which catch the barbell if the user drops the barbell. The two elongated elements would be considered to form an elongated structure together according to the current invention. It could be interpreted that both elongated elements of the prior art systems could be understood as an independent elongated structure, however, according to the current invention, it is understood that the two elements together control the motion of the weight element and as such they are both parts of a single elongated structure.
The terms “upper and lower ends” should be understood as the upper and lower ends of the elongated structure. The claims refer to an axis passing through the upper and lower ends. In the case of an elongated structure having a large cross sectional area, then for the sake of defining the axis, the centre point of the cross sectional area of the upper and lower ends should be used.
Another related, but independent invention is provided in the form of a suspension training based functional fitness element comprising: an essentially planar element having an upper edge, a lower edge and two side edges, said planar element being designed to form a pivotable connection to a support element along said upper edge of the planar element, a first elongated element connected to said planar element at a first connection point at said lower edge of the planar element, a second elongated element connected to said planar element at a second connection point at said lower edge of the planar element, and a first and second handle, said first and second handle being connected to said first and second elongated elements respectively.
In the claims, the term “planar element” should be understood as an object having a width, a height and a length where one of the three dimensions is much smaller than the others. In one embodiment, the dimension is at least 5 times smaller than the others. In another embodiment, the dimension is at least 10 times smaller than the others.
It should also be noted that a “support element” is mentioned in the claims. However, for the sake of the scope of protection, it should be noted that the “support element” is not a part of the functional fitness element itself. Rather the functional fitness element is designed to be connected to a support element.
Another related, but independent invention is provided in the form of a twisting action functional fitness element comprising: a stiff elongated element comprising: a first end, a second end, a first gripping element arranged between the first and second ends, where said first gripping element is offset from an axis which passes through the first and second ends such that a user applying force to the gripping element in a direction perpendicular to said axis can apply a moment to the elongated element about said axis, and a load providing element arranged to provide resistance to pivotal motion of the stiff elongated element.
According to the current specification, the term “load providing element” should be understood as an object which provides a load to the user of the fitness element via which the user can train his or her body.
Fitness machines are well known and many different arrangements of fitness machines are known. Typically fitness machines are part of a fitness system which comprises many different fitness machines, each providing different training exercises. For example a fitness system could comprise one fitness machine which trains the upper body and another fitness machine which trains the lower body.
These fitness machines are typically provided as a fitness assembly which comprises a frame and a functional fitness element. The frame is designed to support the functional fitness element on a support surface. However it is common for many different fitness systems that the different functional fitness elements have different frames. Each frame is optimized for the specific functional fitness element mounted to the frame.
As a consequence, a large number of different frames need to be designed and manufactured. This raises the cost of the individual fitness elements in the system and also leads to more complex stocking systems for the companies manufacturing and/or selling the systems. Furthermore, in many cases, since the typical fitness machines in a system have different frame elements, when arranging different fitness machines into a fitness machine arrangement, the overall visual impression will be that of a number of individual machines set up without any form of logical link between the machines. A disorganized visual impression will then typically be provided by the arrangement.
A fitness system can often be identified by common graphical elements or common structural elements which are shared between the different fitness machines. Such common graphical or structural elements provide a visual impression of unity to the fitness machines when they are erected as a group of fitness machines. A fitness system can also often be identified by reviewing the marketing materials of the manufacturer of fitness machines. Typically different fitness machines will be marketed and sold as part of a system of fitness machines.
Furthermore, very many different functional fitness elements are disclosed in the prior art. Known functional fitness elements all have both positive and negative features.
A first aspect of the current invention is therefore to provide a fitness system which is cheaper to manufacture.
A second aspect of the current invention is to provide a fitness system which is less complex to stock.
A third aspect of the current invention is to provide a fitness system which provides a greater unified visual impression when an arrangement of different fitness assemblies is setup.
This is in part provided via a fitness system as stated in claim 1. By providing such a system, the manufacturer of the system only has to produce one standard frame element and then multiple different functional fitness elements can be attached to and supported by the standard frame element. Instead of having to manufacture and stock many different types of frame elements, only a single variant needs to be made. Of course, additional frame elements could also be provided if necessary, but in general, a single frame element forms the basis for the fitness system according to the current invention.
It should be understood that the current invention is related to a system of elements, which system results in a series of different elements which are then manufactured by one or more manufactures so that they can be assembled into different assemblies.
The system could also be arranged with additional functional fitness elements which allow the creation of multiple other fitness assemblies and thereby further expand the possibilities provided by the system.
In one embodiment, the standard frame element has a length, a width and a height, and the length can be arranged to be more than two or more than three times greater than said width. In this way, a longer and narrower structure can be provided in contrast to a more square structure which is common in the prior art fitness machines.
In an embodiment as specified in claim 4, the capacity of the system can be increased without increasing the number of frame assemblies needed. Since the frame assembly itself and the establishment of proper support for the frame assembly on the supporting surface is in many cases a costly component of the system, reducing the number of frame elements while increasing capacity gives extra benefits to the system. Especially reducing the number of foundations required to setup a fitness arrangement, can provide a large economic benefit. For example, a frame element could be provided with two or three or more fitness stations while having 3 or 4 or fewer foundations.
In an embodiment according to claim 5 an assembly can be provided where the users can work side by side, but without looking at each other. When working face to face, most users will require a larger personal space. However, when working side by side, users can work closer together without the same requirement for a large personal space.
In an embodiment according to claim 6, a tapered frame is provided when looking at it from above. This has a number of benefits as discussed further in the text below.
In an embodiment according to claim 7 a system is provided which further increases the possible capacity of users working on the system at once. Furthermore, the number of different functional exercises made possible by a single arrangement of fitness assemblies will be increased without increasing the number of frames required. Again, the number of foundations required to properly support the arrangement will be decreased while still providing a large number of different exercises.
The current invention relates mainly to a system of elements. However, the claims also relate to an arrangement of fitness assemblies made up of fitness elements according to the system specified in this specification. Claims 8-15 relate to different embodiments of different physical arrangements of fitness assemblies assembled on a support surface whereas claims 1-7 relate to the concept of a system of different elements which make different assemblies possible.
Another aspect covered by the current specification is to provide additional functional fitness elements which provide additional benefits over the solutions known in the prior art.
The current specification therefore also discloses another related but independent invention, namely a weight lifting based functional fitness element as described in the introductory portion of this specification but where the elongated structure has a dimension perpendicular to said axis of less than 20 cm, less than 15 cm, or less than 10 cm. By using a narrow elongated structure, a more simple system can be provided. In most cases, the elongated structure can be provided by a single narrow element. When having a narrow element, the forces on the structure are minimized and there is less risk that the weight element “binds” on the elongated structure. Furthermore, instead of having the user stand “in” the elongated structure as in the prior art, in the current setup, the user will be typically be standing around the elongated structure, and typically be facing the elongated structure with his or her upper body depending on the specific exercise.
In an embodiment according to claim 17, again, a simple mechanical solution is provided. By “linear elongated structure” is meant a structure which is arranged as a straight line between the two ends. The linear structure could either be provided by a stiff elongated element in the form of a rod, pole, pipe, etc. or it could be provided by a flexible element which is held in a manner so that the element is stretched out and held in a straight line.
In an embodiment according to claim 18, a structure is provided which is simple, cheap and robust. Furthermore, the structure is then also flexile and can absorb shock loads and other forces without being damaged or without becoming permanently bent.
In an embodiment according to claim 19, a structure is provided which allows the weight element to displace sideways with respect to the elongated structure. This provides for a more natural motion for the user. Instead of being limited to a purely linear motion, a much more “free” motion is allowed.
In an embodiment according to claim 20, this more free motion is provided in a simple and elegant way without requiring complex mechanisms.
In an embodiment according to claim 21, damage to the weight element can be prevented while also reducing undesired shocks to the fitness element as a whole. This will increase the life expectancy of the fitness element significantly and increase the user friendliness of the element.
In an embodiment according to claim 25, a weight element is provided which allows the user to hold onto the weight element with one hand on either side of the elongated structure.
Additional details of the weight lifting based functional fitness elements are provided in additional dependent claims as well as in the description and figures.
As mentioned in the introductory portion, the current specification also discloses a second related but independent invention. This second invention relates to a suspension training based functional fitness element as described in the introductory portion where said first and second connection points are arranged such that there is a horizontal offset between the first and second connection points and such that there is a vertical offset between the first connection point and the pivotable connection and a vertical offset between the second connection point and the pivotable connection.
By arranging the connections in this way, a more secure suspension training apparatus can be provided. In the prior art systems, two long straps can be dangerous for small children who could try to swing on the straps and crash into each other when they swing towards each other. In contrast, by arranging the elongated elements connected to a planar element, the strap length is shortened and it becomes more difficult to swing on the elongated elements in two different directions.
In an embodiment according to claim 27, the handle becomes easier and more flexible to use for the user. Especially getting his or her feet into the handle becomes easier.
In an embodiment according to claim 28 the safety of the system is further increased. Furthermore, additional area can be provided on the planar element for printing information, for example marketing information or instructional information. In claim 30 an embodiment is disclosed with an area of greater than 50 cm2. However other planar elements with even greater areas could be imagined. For example an area greater than 75 cm2, greater than 100 cm2, greater than 150 cm2 or greater than 200 cm2 could all be imagined.
In an embodiment according to claim 31, a suspension training based functional fitness element can be provided which ensures that the forces acting on the user are more vertical than in the prior art systems.
In an embodiment according to claim 32, the safety of the system is further increased. Furthermore, the stiff plate can provide a more rigid feeling to the fitness exercise.
In an embodiment according to claim 33, it is ensured that the elongated elements do not twist about a vertical axis through the planar element. This makes it easier to control the motion of the elongated elements and makes it easier to get into the handles, especially with the feet of the user.
In an embodiment according to claim 34, it can be prevented that the elongated elements are used as a swing, since the permitted range of motion can be limited. In one example, the range of motion is limited to between +/−60 degrees to the vertical, to between +/−45 degrees to the vertical or to between +/−30 degrees to the vertical. Furthermore, this can prevent the elongated elements from being twisted around an upper support bar.
In an embodiment according to claim 35, the safety and convenience can again be increased. The safety is increased due to the limited motion possible and the convenience is also increased due to the fewer degrees of freedom of the structure which makes getting into the structure easier.
Additional possible details of the suspension training based functional fitness element are provided in additional dependent claims and/or in the description and figures.
As mentioned in the introductory portion, the current specification also discloses a third related but independent invention. This third invention relates to a twisting action functional fitness element as described in the introductory portion but where the elongated element is designed to be pivotably connected to a support element at the first end via a first connection and to be pivotably connected to a support element at the second end via a second connection. In this way, a simpler and stronger structure is provided when compared to many other prior art systems.
In an embodiment according to claim 38 an elongated structure is provided which can be used so that different moments can be applied by different users.
In claim 39 different possible load providing elements are mentioned. A frictional element will be an element where the load is provided by providing a friction against the rotational motion of the elongated element. An elastic element will provide a load which increases as the displacement increases. This could be provided by for example a helical spring, a plate spring, an elastic band or another form of elastic element. A weight based element is one where a physical weight is caused to be displaced. This could be for example, by connecting a weight directly to the elongated element or to the elongated element via a mechanism for example a pulley mechanism. A weight based element could provide an inertial load (which is dependent on speed) and/or a more static load. An electrical machine could be similar to a generator or an electric brake.
In an embodiment according to claim 40, the load is adjustable which allows different users to get different effects from the fitness element. In the case of the frictional element, the friction could be adjusted, for example via a brake which can be tightened. One example is a disc with a disc brake setup. The tension on the disc brake could be adjusted to provide varying loads. In an elastic setup, the tension on the elastic could be adjusted by pre tensioning it, or by adding additional elastic elements. Likewise, the weight element could be adjusted by increasing the inertial mass of the element with respect to the displacement of the elongated element, or additional mass could be added to the weight itself. In the case of an electrical machine based element, the load on the electrical machine could be adjusted.
In a preferred embodiment, the fitness element is arranged essentially vertically. Variations are disclosed in claim 42. This allows a long element to be provided as disclosed in claim 43 whereby a full body effect can be achieved.
In another embodiment, the fitness element can be arranged essentially horizontally. This can provide a different form of exercise than the vertical orientation.
Additional details are provided in other dependent claims and/or are disclosed in the description and figures.
It should be emphasized that the term “comprises/comprising/comprised of” when used in this specification is taken to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof. For example in the claims it is written that the system comprises one standard frame element. However this should be understood as comprising at least one standard frame element. Likewise, in some of the claims a reference is made to one or two users. However, this should also be read as at least one or two users. Additional users are therefore not excluded from the scope of protection.
In the following, the invention will be described in greater detail with reference to embodiments shown by the enclosed figures. It should be emphasized that the embodiments shown are used for example purposes only and should not be used to limit the scope of the invention.
The standard frame element shown in
In order to be able to define the dimensions of the standard frame, a virtual rectangular box is defined (dotted lines in
In the current embodiment shown in the figures, the length is greater than the width. In the actual embodiment the length is about 3.5 times greater than the width. However other ratios could also be used, for example 2 times greater, 2.5 times greater, 3 times greater, 4 times greater or even larger.
It can also be seen in the current embodiment, especially from
By providing a standard frame element which tapers in this manner, the torque loads which can be supported by the frame are higher than a frame having the same narrow width throughout but the material usage of the frame is lower than a frame having the same wide width throughout. Furthermore, the visual impression provided by the tapered frame is smaller than a non-tapered frame since both sides of the non-tapered frame would have to be made larger to support the same torque loads. In addition, when erecting multiple such tapered frames in a fitness assembly arrangement, a visual impression can be achieved where the frames seem to be pointing towards each other. This provides an impression of a connected fitness assembly arrangement, even though the frames are not necessarily physically connected.
The current embodiment of a standard frame element 1 has some very characteristic visual features. While additional details could be read from the figures and added to the claims if desired, it should also be noted that standard frame elements according to the current invention could be formed in many different ways and provide many different types of visual impressions.
The current embodiment 1 of a standard frame element comprises a main frame element 2 which has a generally upwards projecting portion 3 and a generally sideways projecting portion 4. The generally upwards projecting portion 3 is arranged at one side of the frame and is mounted to the ground via mounting plates 5. The mounting plates could in certain cases, depending on the underlying surface, be screwed into foundations which are placed into the supporting surface prior to erecting the frame element. The generally sideways projecting portion 4 is arranged along the top of the frame and is connected at one end to the upper end of the generally upwards projecting portion 3. A vertical frame element 6 is arranged at the side of the frame opposite to the generally upwards projecting portion 3 and is connected to the ground via mounting plates 7 at one end and to the generally sideways projecting portion 4 at its other end. A horizontal beam 8 is furthermore provided along the top of the frame for providing a connection beam for different functional fitness elements.
The frame element 1 of the current embodiment also has a plate element 9 which is fastened to the generally upwards projecting portion 3. The plate element is a metal plate having a surface area which is suitable for applying printed material which explains the use of the functional fitness element arranged in the standard frame element. In the current embodiment the generally upwards projecting portion is formed from two adjacent pipes offset from each other. The plate element is then fasted between the two adjacent pipes. In this way, the plate element 9 can also provide extra stiffness to the frame itself.
The vertical frame element 6 is in the current embodiment formed from two vertically arranged tubes which are offset from each other. The two tubes are connected by smaller tubes which function as a ladder element. These smaller tubes also provide extra stiffness to the vertical frame element 6.
In
The current embodiment of a net based functional fitness element 11 shown in the figures comprises a mix of stiff elements 12, flexible rope like elements 13 and plastic covered rope like elements 14. The stiff elements are in the current embodiment made from vertical metal pipes 12b of about 48 mm in diameter and from horizontal metal pipes 12a of about 38 mm in diameter. The rope like elements 13 are flexible and have a thickness of about 16 mm in diameter. The plastic covered rope like elements 14 are coated with a thick layer of plastic which increases the stiffness of the rope like element while also increasing the diameter thereof to about 38 mm. In the current embodiment, the net based functional fitness element is arranged as a mix of stiff and flexible elements. However, in other embodiments, a net based functional fitness element could be provided comprising only flexible rope like elements or only stiff elements or only plastic coated flexible rope like elements.
The net based functional fitness element 11 shown in the current embodiment is fastened along its upper side to the horizontal element 8 of the standard frame element and is fastened along its lower side to the ground via plates 15 screwed into the supporting surface. The net based functional fitness element 11 shown here is arranged as a planar element and is arranged vertically. However, in other embodiments a net based functional fitness element could be provided which is arranged at an angle to the vertical. In another embodiment, two net based functional fitness elements could be arranged connected along their upper edges to a common support element but then angled outwardly to form a tent like structure with their lower edges connected to the ground at different spaced apart locations.
A net based functional fitness element 11 as shown in
The fitness assembly shown in
As can be seen from the figures, in this fitness assembly embodiment, three suspension training based functional fitness elements 21a, 21b, 21c have been provided on a single standard frame element 1. This will allow three users to simultaneously use a suspension training based functional fitness element each. Furthermore, it can be seen that the three suspension training based functional fitness elements are arranged adjacent to each other and in line with each other. In the current embodiment, the three elements are arranged along the central vertical plane of the standard frame element. In this way, three users can use the suspension training elements while standing beside each other. It can also be seen that the fitness elements are arranged such that the users can use the fitness elements while standing with their bodies facing in a direction which is perpendicular to a vertical plane passing through the two side edges of the standard frame element. In this way, the users will not necessarily be facing each other while using the suspension training elements. This will reduce the risk that a user's personal space is invaded by another user of the fitness assembly while still allowing a high user density on the standard frame element.
While traditionally available suspension trainers could be directly attached to a standard frame element, in the current embodiment, the typical straps and handles of a known suspension training element have been changed to provide additional beneficial features. In particular, instead of a flexible strap with two handles, the suspension training element according to the current embodiment comprises a planar element 22 and two elongated elements 23. The planar element is pivotably attached to the upper horizontal beam 8 and the elongated elements 23 are attached at the lower edge of the planar element. At the end of each of the elongated elements 23, a handle 24 is arranged.
As shown by the arrows A in the right of
In the current embodiment, the handles 24 are attached to the elongated elements such that the handles can rotate with respect to the elongated element about an axis which is parallel with the elongated element 23. In the current embodiment, the elongated elements are rope like elements 23a covered by plastic sheath 23b. In this way, high strength is provided to the elongated element via the rope like element and increased stiffness is provided via the plastic covering. However, in another embodiment, a stiff element, for example a metal pipe could have been used as the elongated element instead. Likewise, in another embodiment, a pure flexible rope like element could be used. One advantage of a stiffer elongated element is that the elongated elements will not twist around each other so much if the element is stiffer.
Furthermore, in the current embodiment, the connection between the elongated element and the planar element is pivotable, but in another embodiment, if the elongated elements are flexible enough, then the connection could be fixed. Furthermore, in the current embodiment, the connection between the elongated element and the planar element is controlled to only allow motion about a single axis, however, in other embodiments, a more free motion could be provided.
The planar element 22 in the current embodiment has an upside down Y shape where the base of the Y is pivotably attached to the horizontal beam 8 of the standard frame and the tips of the Y are each connected to an elongated element. In this embodiment, the distance between the two lower connection points is around 400 mm. This provides a good distance between the elongated elements which ensures that the force which is applied to the user by the elongated elements is mainly vertical. This is in contrast to the traditional strap suspension training arrangement where the strap is hung from a point. For short straps or for exercises which require a short strap length, the straps will have a large component of force acting inwards due to the angle the straps will have to the vertical during use. While the current embodiment has a distance of 400 mm, other distances could also be used, either shorter or longer which fulfil the same purpose of providing a more vertical load on the straps.
In the current embodiment, the planar element 22 is made from a stiff plate element. However, in other embodiments, the planar element could be made from a flexible element. Furthermore, in the current embodiment, the planar element is made from an element which has a surface area which is large enough for printing graphical information thereon. In other embodiments, a planar element could be imagined with an open frame construction which would not be suitable for printing graphical information such as usage instructions or advertising.
A handle 24 of the type used in the fitness assembly of
In the current embodiment, the planar portion 24a and the loop portion 24b form an angle A to each other of about 150 degrees. Due to this, a user can hold onto the grip portion with his or her hand and place a load on it without having the elongated element attached to the handle contact the user's arm. This effect will be further increased by increasing the stiffness of the connection between the handle and the elongated element.
Furthermore, the arrangement also allows a user to place his or her heel on the grip portion 24d with their toes pointing upwards and then support the ball of their foot on the planar portion. This will increase the effectiveness of the support which the handle provides to the user's foot. In this embodiment, ridges are provided on the surface of the planar portion which gives increased friction and thereby better support. While the current embodiment shows an angle of about 150 degrees between the loop portion 24b and the planar portion 24a, other angles are also possible, though typically they will be between 130 and 170 degrees, in another embodiment between 140 and 160 degrees
In the current embodiment, the planar area is solid and has a surface area with ridges. However, in other embodiments, the planar area could be provided as an open frame structure. This will still provide support for the user's foot and still prevent the strap portion from contacting the user's arm during the exercise.
The fitness assembly 30 shown in
The basic principle of this functional fitness element is to use an elongated element 32 and support it between the ground 33 and an upper support element 34 which in this case is the upper horizontal beam 8 of the standard frame element. In the current embodiment, the elongated element is a flexible rope like element which is supported such that the rope like element is stretched out such that it forms a linear elongated element between an upper support point 34 and a lower support point 33.
A weight element 35 is fastened to the rope like element such that it is slideable up and down along the rope like element. In this embodiment an opening in the form of a through going hole is made through the weight element 35. The rope like element 32 is then fed through the through going hole. In this way, a user cannot remove the weight element from the rope like element 32. A user can then train weight lifting by lifting the weight element up and then letting it slide back down again. The user's action is shown schematically in
In the current embodiment, handles 37 are provided on either side of the weight element 35. Due to the arrangement of the weight element in the current embodiment, one handle is provided on either side of the elongated element 32. When the user uses the fitness element, the user will therefore have one hand on either side of the elongated element. In another embodiment (not shown), the weight element could be formed without any handles and the user will hold the weight element directly, for example like a medicine ball. Again, the user could be holding onto the weight element with one hand on either side of the elongated element.
In order to provide extra security during the usage of the fitness element, the motion of the weight element can be controlled. In the current embodiment, a shock absorbing element 36 is arranged at the bottom of the rope like element 32. The shock absorbing element 36 is arranged in the current embodiment as a spring based system which can absorb the energy from a falling weight. If the user lets go of the weight element while it is in a raised position, the shock absorbing element will absorb the energy from the falling weight without risking that the weight element crashes into the ground.
In the current embodiment of the shock absorbing system, two springs are provided in the shock absorbing element, a shorter stiff spring 38 and a longer softer spring 39. When the weight falls down, the weight first engages the first spring 39 which starts to compress. Then the weight will engage the second spring 38 which further compresses. When the weight has stopped moving, the springs are all compressed and will push the weight back up. If there was only a single spring, the weight would be shot back up almost to the same height as it had fallen down. However, with the two spring system, the weight will not be sent so far up.
Furthermore, it can be seen from
In the current embodiment, the lower end of the rope like element is allowed to displace upwards due to the spring mechanism. However, in another embodiment (not shown), the upper end of the rope like element or both ends of the rope like element could be allowed to be displaced. In another embodiment (not shown), instead of allowing the end of the rope like element to displace upwards or downwards, a spring system could be provided which allows one or both ends of the rope like element to displace in a direction which has a vector component which is perpendicular to the longitudinal axis of the rope like element.
In the current embodiment, the control of the motion of the weight is provided by a spring which catches the falling weight via a spring system. In another embodiment, a spring could be built into the weight element itself. Likewise in addition to a spring, a damper could be arranged in the weight or at the bottom of the rope like element which can absorb the energy from the falling weight. For example an oil damper could be arranged in the shock absorbing element. In another embodiment (not shown) the weight element could also be provided with braking means which brake the motion of the weight element when it is dropped. These braking means could provide braking in one direction, but not the other. For example when lifting the weight, no braking is applied, but when moving the weight down, braking is applied. One way braking systems are known in the art and won't be described in more detail herein. Likewise, one could imagine a braking system where the braking effect is related to speed. When moving the weight quickly (for example when dropped) the braking system engages to slow the motion of the weight on the rope. However, moving the weight slowly would not activate the braking system.
Furthermore, as can be seen from
In the current embodiment, three different weight elements are provided. One is 5 kg, one is 10 kg and one is 20 kg. However other combinations could also be imagined, for example, 6 kg, 12 kg, and 18 kg. In the current embodiment, lead elements 44 are embedded in the body of the weight element to provide the weight to the weight element. In another embodiment (not shown) a weight element could be provided where different weight blocks could be added or removed from the weight element to provide an adjustable weight element.
It can also be mentioned that by allowing the weight to get as close to the ground as possible, more exercises can be performed when compared to a system where the weight is not able to get as close to the ground. Therefore, it is beneficial to provide a fitness element which is designed such that the gripping area of the weight element can be arranged lower than 50 cm from the supporting surface. In another embodiment, the gripping area of the weight element can be arranged lower than 40 cm, lower than 30 cm or lower than 20 cm from the supporting surface. The term “gripping area” should be understood as the area on the weight element which is held by the user during the exercise. In the current embodiment, the weight element has multiple gripping areas. One area is the handles and another area is the lower edge of the weight element. In the case of a weight element with multiple gripping areas, all the gripping areas could be arranged as described above, or just one or more of the areas could be arranged as described above.
The fitness assembly 50 in
The basic principle of operation of the current embodiment is that an elongated element 52 is twisted by a user against a resistance force. An elongated element in the form of a bent metal pipe 52 is provided which is pivotably supported at its upper end 53 and its lower end 54. A portion 55 of the elongated element is offset from the axis between the upper and lower ends. A user can then hold the offset portion 55 and twist the elongated element about its rotational axis. The elongated portion 55 is a form of gripping element according to the language of the claims. A load providing element, in the current embodiment called a braking element 56, is arranged at the upper end of the elongated element to provide resistance to the rotational motion of the elongated element. In the current embodiment, the braking element is provided at the top of the elongated element, but in another embodiment (not shown) a braking element could also be provided at the lower end of the elongated element or at both the top and bottom ends.
The braking element 56 could take many forms. In the embodiment shown in the figures, an electrical machine based braking device is used. By adjusting the load on the machine, the effort required to turn the machine will increase or decrease. In other embodiments, a friction based brake could be used where the user can control the frictional level to control how much effort is required to twist the elongated element. In such an embodiment, the force will be independent of rotational position. In another embodiment, the braking device could comprise an elastic element whereby an elastic effect is provided similar to a spring. In such an embodiment, the force becomes larger and larger as the elongated element is rotated more and more.
As can be seen from the figures, the current embodiment of the elongated element 52 has a first elongated portion 55 offset from the axis of rotation as well as a second elongated portion 57 which is also offset from the axis of rotation, but not as much as the first elongated portion 55. The first and second elongated portions 55 and 57 could be considered first and second gripping elements. A user can choose to hold onto the first or the second elongated portion. When the user holds onto the first elongated portion, the load provided by the braking element will be smaller than when the user holds onto the second elongated portion due to the difference in moment arms provided by the two elongated portions. This can be used to provide different exercises and loads to different users. Stronger users will be able to hold the inner element while weaker users will hold the outer element.
In the current embodiment, the elongated element comprises gripping elements arranged with a vertical axis and offset from the rotation axis of the elongated element. In another embodiment (not shown), the elongated element could comprise gripping elements which are arranged extending perpendicular to the rotational axis of the elongated element. For example, the elongated element could be a straight metal tubular element connecting the upper and lower ends of the elongated element. A straight bar could then be fastened to the elongated element such that it extends perpendicularly to the longitudinal axis of the elongated element. A user could then hold onto the straight bar and apply a moment to the elongated element. By holding onto the straight bar in different positions, different moments can be applied to the bar. To support users of different heights, multiple straight bars could be mounted to the elongated element at different heights. In this case, the elongated element would comprise multiple gripping elements in the form of bars connected to the elongated element at different heights.
In general, one could also mention that the fitness element shown in
By erecting multiple fitness assemblies together, a more complex fitness assembly arrangement can be provided whereby multiple different exercises can be practiced.
As can be seen from
It should be noted that in the current embodiment shown in
Likewise
Additional functional fitness elements can then be attached to the link element. In the current embodiment, suspension training based functional fitness elements 21 are connected to the link element. Using such link elements, a simple structure comprising just two standard frame elements can host three separate stations.
Such link elements can also be used when there are more than two standard frame elements. One example (not shown) is a structure similar to the one shown in
Some different non limiting examples of functional fitness elements which could be connected to the link element is a rope mesh based functional fitness element similar to the arrangement of
In the embodiment shown in
It can also be noted that in the current embodiments, similar functional fitness elements have been mounted on a single standard frame element. However, it could also be imagined that a single standard frame element had different functional fitness elements mounted on it. For example, in one embodiment (not shown), a standard frame element could be provided which had connected thereto, a twisting action functional fitness element, a suspension training based functional fitness element and a weight lifting based functional fitness element.
