Field of the invention

The invention relates to exercise equipment, more particularly to a multi-position, multi-purpose portable exercise unit including a profile integrated as part of a door frame or mounted on a wall. Background of the invention

There is a lack of equipment and solutions specifically designed for user groups which are in significantly growth, e.g. pensioners, rehabilitators and weight watchers. The need is basically a simple, cheap and easy to use training and exercising equipment, without any major footprint during usage or when stewed away. Typical of the equipment of today is that they are designed for those attending gyms and training centers. The equipment is rather advanced, costly and occupies a lot of space. The main users are women or men from the 30's to the 50's full of energy and ambitions.

The new identified user groups like pensioners, rehabilitators and weight watchers are quite different - their attitude is rather low key and easiness. Their all in all need is to move, have fun and make repetitions rather than heavy impacts. Pensioners are part of a mega trend, in the following ways; They increase in numbers due to among others their increased standard of living, the countries increased gross national products (GNP), the new medicines and treatments, the general increased concern about health and way of living, etc. This is also caused by the baby boom after the World War II. The actual number of pensioners citizens will increase significantly in the coming decades. This will challenge the society, the municipals, the families and friends and themselves, as they will challenge the public and private health institutions. They are also deemed to take more actively care about themselves, both physiologically and psychologically. Today, the number of those in the 65's and outwards represents approx 20 % of the population of Norway. In the next decades, the relative percentage is expected to increase to almost 25 to 30%. Pensioners need to be physically active, for various reason otherwise they will get stiffer as their normal muscles are not in practice. One aspect is the well known correlation between mental condition and various diseases like cardiovascular, dementia, etc. A new aspect which is slowly getting the attention is falling accidents. It is well known from the US (Washington State) that number of deaths actually caused by falling accidents of pensioners outnumbers those killed or dying by car accidents. The same applies for the corresponding public or private costs for hospitalization and treatments. There is a growing concern about how to reduce these falling accidents. Cardiovascular diseases are mostly linked with the standard and way of life and physical condition. One aspect is how to avoid these cardiac disease, but also how to train to rehabilitate after a stroke. The same applies for persons who have been exposed for accidents, diseases or surgery, where there is a need to recover or rehabilitate. The last user group considered is the weight watchers. Thicker people, or especially those with a body mass indicator above what is recommended is increasing, is the last segment. The industry supplying weight reductions ingredients are booming as a result. However, the best effect what so ever is gained by having a normal happy life, eating the right food and have a certain level of physical activities.

Doors have in the past been used for mounting a variety of exercise devices. Examples of such mountings are: Ripp US Pat No. 4,304, 402 entitled Dynamic Exercise Equipment. In this disclosure a flexible exercising equipment is invented with a foot hold for providing a fixed and steady point for conducting exercised.

Pagani, US Pat No. 4,373,716 entitled Exercising Device. In this disclosure a flexible exercising equipment is described utilizing rods which is basically carried by the user in order to provide a backstop for the flexible strings.

Pollock US Pat No 5,254,065 entitled Flexible Loop Fastening Strap Supportable in Door Structure. In this disclosure, a strap having an enlarged end portion is trapped on one side of the door with a loop depending to the opposite side of the door. The loop acts as the anchored point from which a portion of an exercise device may be attached. McFall et al, US Pat No 5,468,205 entitled Portable Door Mounted Exercise Apparatus. In this disclosure, two large pulley assemblies are mounted to the top and bottom of a door. The pulley assemblies have elastic members connecting the top pulley assembly to the bottom pulley assembly. The disclosed pulleys have relative large diameters and are canted out of the plane door so that they may swivel about an axis tilted toward the person utilizing the exercising device. Weintraub US Pat. No. 5,601 ,518 entitled Portable Exercise Device. In this disclosure, top and bottom U-shaped brackets mount to a door to suspend an otherwise elaborate exercise device. Upper brackets and pulleys together with a lower level produce a large essentially not portable exercise device.

Saure US Pat. No. 6,908,418 entitled Door Mounted Deadman for Exercise Devices. In this disclosure, a door-mounted strap extends around a door in the vertical direction. On the deadman side of the door, the strap is continuous as it faces the exerciser. D-rings are sewn at intervals to the strap. Removable and attachable elastic members are fastened to the arcuate portions of the D-rings. These D-rings and elastic members are providing in combination with handholds, limb straps, at the like to enable standing, sitting or prone exercise positions.

Previously known door-mounted devices suffer from at least five deficiencies. Firstly, most known devices are aimed at those physically fit, either to assemble the device and/or to be able to actually handle and hold the devices while training. Secondly, most devices mount relatively large mechanical structures to the door in the form of pulleys, levers, top and bottom mounted (typically U-shaped brackets. These large mechanical structures subtract from the exercise device's portability, which is a principle reason for mounting the device to a door in the first place. Thirdly, these devices locally strain the door edges, usually at the top or the bottom of the door. These local strains on the door edges render device mounting damaging to the door and can produce hazardous conditions. Fourthly, exercising e.g. facing a closed door provides not optimal support ability, neither for the user groups like pensioners nor those on rehabilitations. At certain circumstances, there may be a need for third- parties to enter through the door to examine if everything is fine, like nurses, family relatives, friends or instructors. Fifthly, typical assembly of exercising devices, are not that easy for the mentioned user groups. If the profile is already a part of the door, either integrated or mounted adjacent, the add-on training devices can easily be mounted and dismounted.

Summary

The invention has been defined in the claims.

In the following description, reference is made to the structure of a door. As used herein, a door closes between two doorjambs, with a lintel extending across the door top. Typically, the door is mounted by hinges at one doorjamb as swings to and from positions of engagement of a lock set to the other doorjamb. This specification is based upon that the door may be closed or open.

The present invention overcomes the deficiencies in the prior art by, inter alia, introducing a profile list which can either be integrated as part of the lock set doorjamb or fastened to the wall adjacent to the lock set doorjamb. A holder is lockable to the profile of the list at various locations by e.g. lock pins. The holder is removable. A locker is lockable to the lock set hole of the doorjamb itself or to similar holes of the profile list outlined herein. Removable attachment elastic members for fastening to the holder or locker are provided in combination with handholds, limb straps, and the like to enable standing, sitting and/or prone exercise positions. The elastic members of the exercise device are tensile members, which are portable except for the profile list. An advantage of the disclosed profile list and its location is that it imparts all strain on a distributed basis to the building structure. Furthermore, another advantage is that the door frame will provide a physical support for the user while standing compared to working out next to a wall or a closed door. An example is that the user may stand in the door gap facing the lock set doorjamb while exercising its feet by limb traps. It would then be easy for the user to grab or lean on the door jamb, if needed.

The present invention provides a flexible and simple training concept with a corresponding technology and equipment, specifically targeting segments whose needs are emerging significantly. The new segments are pensioners, implying those above approx. 65 years of age, those on physical rehabilitation due to surgery or cardiac illnesses and those who need to watch their weight. The new concept outlined herein consists of a mix of standard items combined with new training technology. The new training concept is based on providing a fixed point for string exercises. The fixed point is ensured by a list where one or multiple fixed points can be positioned at multiple levels according to the user and training devices to be used. The list can be mounted on a wall (indoors or outdoors), adjacent to a door frame or actually be integrated as a natural part of a door frame. Brief description of the drawings

Fig. 1 is a schematic diagram illustrating aspects of an exercise equipment to be mounted at a door passage.

First an example of the profile list 1 will be described, secondly the holder 5 with lock pins 6, thirdly the locker 50 and then a flexible string device 10 to be hooked onto the holder 5 or locker 50 prior to exercising.

Referring to Fig. 1 , the door 4 is open. The lock set 3 and the lock set doorjamb 2 are shown. The profile list 1 is screwed adjacent to the lock set doorjamb 2. Multiple locations for the holder 5 are shown. Actually three positions are presented on the figure. The holder 5 is locked to the profile list by double set of lock pins 6. The holder 5 can be mounted in two directions, upon the user should consider in which direction the forces will be imposed. As the forces are mostly made downwards the insertion slice shall be directed upwards, as this represent the weakest point of the holder's crook.

The profile list 1 as illustrated in Figures 1 , 2, 3, 4, 5, 6, 7 and 8 as well as 15, 16 and 17, is preferably made by extruded aluminum or plastic or bended aluminum or steel mechanically at work-shop. The profile list 1 will typically have a hat shape profile, fitting the shapes of the doorjambs. The hat shape can for instance by 1 cm high and 3 cm wide, and the total wide of the list can be e.g. 7 to 10 cm. The hat is perforated horizontally by holes (61 or 62) which can be circular, like 0,7 cm in diameter or of any other shape, like oval etc.. The holes (61 or 62) are made at regular distances, either by a drilling or punching at a work-shop or grouped in pairs with a longer distance between each pair. By punching the holes 61 , the material can be moved inwards and make up an area for friction and support of the locking-pins 6 which may be insertable and removable. The hat shape shall mate the corresponding female hat profile of the holder 5. Alternatively or in addition to the holes (61 or 62) outlined above, the hat can have perforated holes 60 similar to the dimensions of the lock set holes. The length of the list 1 can be like the height of the doorjambs or for instance 1 or 2 meters. The profile list is performed by holes for screws, in order to mount the list 1 to a wall. There can be several shapes of the profile lists 1. Fig. 1 , 2 and 4 as well as 15 and 17 illustrate example of a uniform shaped profile list 1 screwed or glued to the wall adjacent to the lock set doorjamb 2. Figure 3 illustrates several shapes of the profile list 1. With respect to Fig. 3 and its alternative 1 , for instance two equal profile lists (1.1 and 1.3) each facing indoors and outdoors respectively while the profile list 1.2 lacks one of the wings on the side of the hat. These profile lists (1.1 , 1.2 and 1.3) could typically be welded to each other and be made by aluminum or steel. With respect to Fig. 3 and its alternative 2, the indoor profile list 1.2 is welded to the profile list 1.3. With respect to Fig. 3, alternative 3, the profile list 1.2 is applied. In terms of usage, usage of profile lists (1.1 and 1 .3) enables exercises to be done when the door is open or closed. Fig. 3, profile list 1.2 requires all that the door is opened during exercising. Walls are usually strengthened next to the door frame by timber or any other materials like steel, solid bricks, concrete. Mounting a profile list in this area provides a solid foundation for the profile list 1 , in order to take up imposed forces. Utilization of this feature is part of the invention in terms of applying a profile list for exercising. Likewise, a door frame equipped with integrated profile lists (as outlined in Fig. 3) is novel, as the door frames capabilities are extended beyond what is known in the art. This also includes utilizing the lock set hole 60 as such as a mating point for a male locker holder 50, providing support for various exercising devices, like the string device or string 10. The profile list 1 is equipped most preferable with wings on each side of the hat-shaped profile, in order to encompass any imposed torsion forces generated by exercising activities.

The holder 5 illustrated in Figures 1 , 2, 6, 7 and 8 is preferably made by cast or milled hard plastic or aluminum. The holder 5 can for instance have a foot print which is square, rectangular or having other geometric designs, in order to withstand especially impacted torsion forces. The foot print size as a square can be, e.g., 7 cm x 7 cm. The high of the bottom section can be 2 to 4 cm, and it should be higher than the height of the hat of the profile list 1. The bottom section is provided with holes mating the corresponding holes of the hat profile of the profile list 1. These holes may be made by drilling or can be part of a casting model. Locking-pins 6 have tolerance dimension which is slightly less than the holes of the holder 5 and profile list 1. The locking mechanism can be of any type. The lock-pins are cast or machined hard plastic, aluminum or a strong durable material. The holder 5 includes a crook. The crook is illustrated particularly in Fig. 6, 7 and 8. The crook can be of any type, but it may advantageously include a threading opportunity for the flexible string 10 with its mid-string

arrangement of steel ball 20 and plastic hose 21. The illustrations present for instance a threading opening which is located on one side of the crook and tilted. The dimensions of the thread zone fit just the overall dimension of the string 10 including the steel ball 20 all covered by a plastic hose 21 with a defined tolerance. Fig. 2 is a schematic diagram illustrating aspects of an exercise equipment operated by a user.

Referring to Fig. 2, usage of the holder 5 apparatus is illustrated. The user 8 pulls in the flexible strings 10 which are hooked up onto the holder 5. Fig. 2 illustrates a principle usage of the equipment comprising a profile list 1 , a holder 5 locked to the profile by a set of locking-pins 6 and a flexible string 1 1 that may e.g. be formed by rubber. The upper part of figure 2 shows the door passage from the front, while the lower part of figure 2 shows a sectional view at the point where the holder 5 is attached to the profile list 1.

Fig. 3 is a schematic diagram illustrating aspects of a profile list.

The upper part of figure 3 shows a front view of the door passage, the lower left part of figure 3 shows three alternatives for a profile list, while the lower right part of figure 3 is a sectional view taken at B-B in the upper part of figure 3. Referring to Fig. 3, three alternatives for profile lists 1 (alternative locations and numbers of profiled lists have been identified at 1.1 , 1.2 and 1.3), are shown. The profile list 1 may be integrated into the lock set doorjamb 2. One alternative, Alt. 1 , illustrates how three profile lists all together can make a complete outer lock set doorjamb. This will allow the user to be on both sides of the door wall as well as stand in the middle of the door passage. Alt. 2 illustrates two locations of the profile list 1 in the lock set doorjamb 2, as the user may be positioned on one side of the door or in the middle of the door passage. Alt. 3 illustrates one location where the user stands in the middle of the door passage.

Fig. 4 is a schematic diagram illustrating further aspects of a profile list. The upper part of figure 4 is a front view of the door passage, while the lower part of figure 4 shows a sectional view taken at C-C in the upper part of fig. 4. Referring to Fig. 4, the profile list 1 is screwed or glued to the wall adjacent to the lock set doorjamb 2.

Fig. 5 is a schematic diagram illustrating further aspects of a profile list. The lower right part of figure 5 is a front view of a portion of the profile list, the lower left part is a side view of the portion of the profile list, while the upper part of figure 5 shows a sectional view taken at A-A in the lower right part of fig. 5. Referring to fig. 5, some examples of the profile list 1 is presented. The profile list has a "hat" profile which mates perfectly the opposite profile of the holder 5. The profile list 1 is perforated by holes which can be of different sizes and lay-outs, like presented in the figure. The holes shall fit the lock-pin(-s) 6 and the design of the holders 5 and/or lockers 50. The profile list 1 can also be perforated by locker holes 60 similar to lock set holes 3. The perforated locker holes 60 are typically positioned on profile lists 1 of length similar to a doorjamb at its bottom closer to the floor, at for instance the middle at the level where lock set's are normally located and closer to the other end.

Fig. 6 is a schematic diagram illustrating aspects of the attachment of a holder to a profile list. The lower part of fig. 6 is a front view of a holder attached to the profile list, while the upper part of figure 6 shows a sectional view taken at D-D in the lower right part of fig. 6. Referring to Fig. 6, the holder 5 is mated and locked to the list 1 by e.g. two lock-pins 6. Fig. 7 is a schematic diagram illustrating further aspects of the attachment of a holder to a profile list. Referring to Fig. 7, the holder 5 is mated and locked to the list 1 by lock-pins 6. The thread of the crook is illustrated. The thread has an offset angle and a geometry fitting the midsection of the string device 10. Fig. 8 is a schematic diagram illustrating aspects of a holder and a crook. Referring to Fig. 8, the holder's 5 crook is cut, in order to outline a suggestion of the internal design of the crook, designed in order to keep the string device centre stabile during use of the exercising equipment.

Fig. 9 is a schematic diagram illustrating aspects of a flexible string device. Referring to Fig. 9, the string 10 is a commodity flexible string with handholds or footholds 1 1 at each end's of the string. The handholds or footholds 1 1 are locked to the string by suitable locking mechanisms. The mid-section of the string is mounted with a ball 20, e.g. a steel ball, and clamped to a fixed and steady position of the string by a clamp 21 of a hose, e.g. a plastic hose.

Fig. 10 is a schematic diagram illustrating further aspects of a holder and a crook.

Referring to Fig. 10, the holder's 5 crook is designed in such a way that the string 10 with its steel ball 20 and hose 21 are threaded into the holder 5. The figure also illustrates the ability of the crook to withstand force impacts, indicated by forces P1 , P2, P3, P4.

The arrangement of the holder's 5 crook as illustrated in Fig. 10, where the thread opening faces upwards, means that exercising forces are best impacted by pulling substantially downwards. The holder can be turned into the opposite direction, in order to provide exercising abilities for pulling the string substantially upwards.

The string device 10 may be made by materials like rubber or other elastic materials. The design of the string device 10 can be like a hose or band. The ends of the string device may be equipped with holders 1 1 which can be universally designed or designed specifically for hand or foot usage. The total length of each string device 10 and the tension of the string device may vary in accordance with the type of exercise and the current ability and ambition of the user. At the centre point of the total length of the string device 10 a fixed backstop is made, by applying a ball 20, e.g. a steel ball, typically of 5 mm in diameter, compressing the string 10 which is either made of rubber tube or a rubber band compressed to a thickness of e.g. 2 to 3 mm all encompassed by a piece of a hose 21 , e.g. a plastic hose, of 0,5 to 1 mm in thickness and a length of e.g. 5 to 10 cm. The steel ball 20 may be positioned at the middle of the length of the string device 10, pressed into the string material and a plastic hose 21 may be compressed around, by e.g. glue or welding.

Fig. 1 1 is a is a schematic diagram illustrating aspects of a locker. Referring to Fig. 1 1 , the locker 50 is a manual insert and lock and unlock and remove design. The locker 50 comprises a house 51 , an internal locker 52 to be inserted in the lock set hole 3, and a flexible lock mover 53 which is kept in its location by a spring plate 54 fixed to the internal locker 52 by a screw 55. The internal locker 52 and the flexible lock mover 53 are made fixed to the lock set 3 of the doorjamb 2 by turning manually the locker/unlocker screw 56. When opening the locker 50, the locker/unlocker screw 56 is unscrewn and the unlocker pin 57 mounted by the bolt 58 to the house 51 is pushed manually inwards, such that the flexible lock mover 53 is positioned well out of the reach of the lock set's 3 dimensions. Then the locker 50 can be removed from the lock set 3. Typically, there is space below the lock set plate 3. The assembled locker 50, as illustrated in Fig. 1 1 , is a device which can be inserted and locked into the lock set 3 and its lock set hole 60 of the lock set doorjamb 2. The locker device consists of one or two symmetrical house parts 51 which encompassed the components like the internal locker 52 and a flexible lock mover 53, all made by cast or milled aluminum or hard plastic. A spring plate 54 made by spring metal, may be screwed to the internal locker 52 by a screw 55. A locker/unlocker screw wheel 56 made by cast or milled hard plastic or aluminum and milled threads interfacing the opposing threads of the internal locker's 52) upper tap. A moveable bolt 57) by e.g. steel or hard plastic is assembled into a nut 58 of e.g. hard plastic or aluminum structure which is integrated into one part of the locker house 51. Three sections are shown, A-A, B-B and C-C.

A crook 58 is incorporated as a part of the house 51. The flexible lock mover is shown as well as the internal locker 52 and its screw 55. The unlocker pin 57 is also shown. Fig. 14 is a schematic diagram illustrating further aspects of a locker. Referring to Fig. 14, the locker 50 is seen from above. The unlocker pin 57, the crook 58 and the locker/unlocker screw 56 are all shown.

Fig. 15 is a schematic diagram illustrating an exercise equipment which includes a locker. Referring to Fig. 15, the locker 50 is locked to a profile list 1 mounted adjacent to a door frame's doorjamb 2. Fig. 16 is a schematic diagram illustrating possible aspects of a profile list. Referring to Fig. 16, three alternatives for profile lists 1 (alternative locations and numbers of profiled lists - 1.a, 1 .b and 1.c), as integrated into the lock set doorjamb 2a. One alternative, Alt. 1 , illustrates how three profile lists all together can make a complete outer lock set doorjamb. This will allow the user to be on both sides of the door wall as well as stand in the middle of the door. Alt. 2 illustrates two locations of the profile list 1 in the lock set doorjamb 2a, as the user may be on one side of the door or standing in the middle of the door. Alt. 3 illustrates one location, where the user stands in the middle of the door passage. The list profile may be identical with the ones of Fig. 3, except that holes are perforated mating the locker 50 at the top of the "hat" of the list profile's 1. The figures denoted 1 .a-1.c show possible intersectional views taken at the section K-K. Fig. 17 is a schematic diagram illustrating possible aspects of a profile list. Referring to Fig. 17, the profile list 1.d with perforated holes for the locker 50 is screwed or glued to the wall adjacent to the lock set doorjamb 3.

Fig. 18 is a schematic diagram illustrating the use of an exercise apparatus which includes a locker. Referring to Fig. 18, the user 8 stands in the door passage exercising with its string device 10. The locker 50 is locked to the lock set 2 of the lock set doorjamb 3.

Fig. 19 is a schematic diagram illustrating possible exercising activities which can be executed by users of the exercise equipment. Referring to Fig. 19, outlines various principle exercising activities which can be executed by users of various sizes in order to train different muscles by string device 10, using either the locker 50 or holder 5 devices.

Fig. 20 is a schematic diagram illustrating a portion of a profile list equipped with a holder which includes a clamp and a handle.

In the aspect illustrated in figures 20 and further illustrated in figures 21 and 22, the profile list 1 is provided with a groove along its length. The removable holder includes, in this aspect, a bow-shaped clamp 30 with a base adapted to slide in the groove along the length of the profile list 1 , and a handle 40 pivotedly arranged in the clamp 30. The handle 40 is arranged in such a way that the handle 40 may be moved into a locked position with respect to the profile list 1 by imposing a force outwards between the base of the claim 30 and the inside of the groove along the length of the profile list 1. In this way the position of the holder may easily be changed by a user of the exercise equipment. Fig. 21 is a schematic diagram illustrating further aspects of a holder with a clamp and a handle.

The handle 40 has a proximate part 41 , proximate to the pivotable connection with the clamp, and an opposite, distal part 46. A flexible string device 10, possibly provided with a sleeve or hose 45, is inserted into a gap of the proximate part 41 of the handle 40. The back part 46 of the handle 40 is entered into the string thread 31 of the bow-shaped clamp 30. The handle 40 is moved backwards until it stops by the turning section of the front part 41 of the handle. This enables the assembly of the clamp 30 and handle 40 to slide up or down on the profile list 1 , until it is positioned and fixed at a desired location.

The holder 30 can be mounted in two directions, i.e., with the handle end 46 facing up or down. The user should consider in which direction the forces will be dominantly imposed. For instance, if the force during use is directed substantially downwards, the handle end 46 should also be directed downwards, as this provides the strongest support.

Fig. 22 is a schematic diagram illustrating further aspects of a holder with a clamp and a handle. Referring to Fig. 22, the handle 40 is shown in its unlocked (A) position and its locked position (B).

The handle 40 illustrated in figures 20, 21 and 22 may preferable be made by cast or milled hard plastic or aluminium. The handle 40 may have of a front end (41 ) which will encompass a supportive structure for incorporating the string device 10.. The overall dimensions may typically be within length 15 to 20 cm, with a grip fitting a person's hand. The width of the handle interface may be in the range of 4 to 7 cm. The handle 40 may be arranged to lock the holder, including the clamp 30 and the handle 40, to the profile list 10 even when a string device 10 is not present. Fig. 23 is a schematic diagram illustrating a portion of a profile list for use with a threaded fastening member. The lower part of figure 23 illustrates a front view of a portion of such a profile list, while the upper part of figure 23 shows a section taken at A-A of the lower part. As can be seen, the profile list is provided with a groove along its length, in order to allow a fastening member to slidably mounted in the groove. Fig. 24 is a schematic diagram illustrating a fastening member with internal threads. The lower part of figure 24 illustrates a front view of such a fastening member. The upper part of figure 24 shows a section taken at B-B of the lower part, while the intermediate part of figure 24 shows a section taken at a section taken at A-A of the lower part, As can be seen, the fastening member is provided with a groove along its length, corresponding to interact with the groove in the profile list illustrated in figure 23, in order to allow the fastening member to be slidably mounted in the groove. The fastening member is provided with a circular a bore with internal threads, allowing screw device with external threads to be mounted in the bore.

Fig. 25 is a schematic diagram illustrating a screw device for use with a fastening member with internal threads. The screw device allows the fastening member to be arranged in a fixed position along the length of the profile list when the screw device is rotated in order to be pressed against the profile list. As also illustrated in figure 25, a hook or crook may be arranged on a portion of the screw device, resulting in that the flexible string device will be arranged to be hooked on a portion of the fastening member which is attached to the profile list.

Although one removable holder has been illustrated in the figures, it should be understood that one or more additional removable holders, which are lockable at various locations to a profile of the profile list, may be included in the exercise equipment. For instance could two or three removable holders be arranged lockable to one and the same profile list.
