Description

The present invention is in the sports field, more particularly in the practice of home bodybuilding.

The invention more particularly relates to a removable device for bodybuilding.

The practice of bodybuilding at home requires devices often heavy and bulky. So it was imagined a lot of material to be able to practice this sport at home, trying to minimize the constraints related to the storage of the device when not in use.

The most common device is simply a bar that attaches to the door jamb, more particularly inside the splay at the uprights.

A well known device consists of a telescopic bar, arranged inside the door splay, coming to support on both sides at the vertical uprights of its frame. The maintenance of such a bar is achieved by the pressure exerted against the amounts, countering the weight of the user. Such a bar has the advantage of having a variable length allowing it to adapt to the width of the frame of the door.

However, it is often necessary to fix this bar at the uprights, especially by screwing into the frame, the pressure exerted is not sufficient to maintain it in front of the traction exerted by the weight of the user.

Another attachment consists of spoilers screwed on the inside of the uprights and intended to receive the ends of the bar, making the latter easily removable. However, this type of attachment does not prevent the rotation of said bar and leaves visible said fasteners on the uprights.

In addition, thus fixed, such a bar can no longer be easily moved to the height of the door, limiting in number the weight training exercises it offers.

Other devices try to offer better support at the level of the splay of the door. For example, the document US 4,458,894 describes an armature consisting of a central bar as previously mentioned and being fixed in a similar manner. This frame is secured to an additional bar shifted through the arms of offset, so as to extend above the door splay, on one side of the wall. Thus arranged in the upper part, this bar offers other possibilities of exercises.

In order to avoid the pivoting of the armature, the latter comprises locking elements in rotation of the central bar. To do this, two stops come to rest on both sides of the splay, on the amounts, on the side of the wall where the additional bar is located.

As previously mentioned, such a device does not overcome a definitive fixing of the central bar at the level of the amounts within the splaying.

The document US 4,529,191 discloses another device having an eccentric bar on one side of the splay. This offset of the bar is compensated by a holding through two stops bearing on the inside and outside of the uprights, to prevent rotation of the device relative to its attachment, always at the inside of the doorframe.

If such a device improves holding and locking in rotation, it is again necessary to screw on the inside of the splay, at the amounts of the fasteners, especially in the form of spoilers, to counter the action the weight of the user.

It has therefore been imagined devices whose positioning and maintenance are easier at the splaying of a door, requiring no final fixation by screwing on the amounts.

An example is described in the document GB 2,299,520 a device consisting of an armature provided with a bar bearing on one side of the uprights, inner or outer, and connected to a suspension plate to the plinth of the lintel located on the opposite side of the wall. This plate comes to rest on the edge formed by the width of plinth so as to offer a vertical lock, countering the weight of the user. Said frame also includes an additional bar offset.

The weight of the user at the offset bar, causes the rotation relative to the longitudinal axis of the eccentric bar bearing on one side of the uprights, ensuring that said plate is always in contact with the upper edge of the plinth.

However, the vertical support thus generated is likely to deteriorate the frame. Indeed, the lintel has no underlying masonry element at the level of the splay, so that the support on the plinth can cause the tearing of the latter.

In addition, the splay must have a plinth to ensure maintenance.

Like existing devices, this type of support does not allow positioning of the device other than in the upper part of the splay.

The invention aims to overcome the disadvantages of the state of the art by providing a removable weight training device whose maintenance is freed from any final fastening element in the frame.

In addition, its particular configuration makes it, on the one hand, adaptable to all dimensions of splaying, with or without frame, and secondly, adjustable in height. This last feature offers a wide range of exercises that known devices do not currently offer.

To do this, the removable device according to the invention consists of a frame shaped so as to cooperate by locking by bearing against the vertical uprights of a splay, said frame comprising at least one telescopic bar, each of the free ends is provided locking means of said device by pressing against said amounts.

It is characterized in that said locking means comprise at least two stops front and rear spaced so as, on the one hand, bear on each side of each amount and, secondly, ensure the blocking of said device only under the effect of its weight through a center of gravity eccentric on one side of one of said stops.

The present invention relates to a device 1 of bodybuilding. It is intended to be subject to a support, more particularly amounts 2 spaced relative to each other. He will find a particular application, but in no way limiting, within a fire, including a door or the like.

Such a device consists of a frame shaped so as to cooperate by locking by bearing against the uprights 2 vertical splaying.

As mentioned above, the invention aims to maintain within the splay without requiring final fixing means. To do this, the locking device 1 is by pressing on said uprights 2 and only under the effect of its weight.

Note that only the weight of the device 1 is sufficient to ensure its maintenance within the splaying. However, device 1 is shaped so that the addition of the weight of a user improves its blocking at said amounts 2.

As such, said armature may comprise at least one bar 3. In one piece, it may also be provided telescopic so as to adapt in size to the width of said splaying. The telescopic appearance can be conferred through two sections 3A and 3B of said bar 3 of different sections relative to each other, so as to slide one 3A within the other 3B under the action of adapted means. According to one embodiment, these means are resilient return means and may be constituted by a compression spring slid inside a first section and pushing the other section from a compressed position to a deployed position in which the device 1 fits inside the splay at the uprights. According to another embodiment, not shown, this spring can be located externally. One can imagine other means of actuation or adjustment of the sliding, in particular through a thread or other.

It will be noted that said bar 3 can be made of any type of material, preferably metal, for example stainless steel.

In the exemplary embodiment, the longitudinal axis of said bar 3 extends parallel to the lintel of said splaying.

Each of the free ends 4 of the bar 3 is provided with locking means 5 of said device 1 by bearing against said uprights 2. As visible on the Figures 5 and 6 these locking means 5 can be slidably mounted along said bar 3. More particularly, said locking means bear on each side of each upright 2, front and rear face of the splaying.

In addition, said locking means 5 comprise at least two forward stops 6 and 7 rear spaced so as, firstly, bear on each side of each amount 2 and, secondly, ensure the blocking said device 1 only under the effect of its weight. This blocking is possible and sufficient through an eccentric center of gravity on one side of one of said stops 6 or 7.

According to the preferred embodiment, said center of gravity is eccentric on the side of the front stop 6 so that the latter constitutes a pivot point of said device 1. Thus, in front support of an amount 2, the front stops 6 serve as an axis around which the device 1 is rotated. This action drives the rear stops 7, located on the other side of each upright 2, so that they bear against the opposite side.

According to a preferred embodiment, each front stop 6 and rear 7 is covered, at its contact area and bearing with the uprights 2, a material 14. Particularly visible on the figure 4 this covering material 14 may be made of elastic material, in particular of natural or synthetic rubber, rubber, silicone or the like, and may be shaped like a grip. To do this, it may have an outer surface grooved or grooved. It improves the sliding resistance of the device 1 and prevents it from descending along the uprights 2.

Note that the front stop 6 may advantageously have a circular shape, such as a wheel 22. The latter can be mounted free in rotation to facilitate the establishment of the device. According to the embodiment visible on the figure 6 this wheel 22 may also comprise a washer 23 protruding internally so as to slide on the inside of the upright on which the stop before 6 is supported.

In addition, the front stop 6 may then consist largely of the material 14, having in its center rolling means, for example of the ball bearing type, mounted on a pivoting axis on the element 10.

As visible on the figure 3 it will be noted that the front stop 6 can be displaced vertically with respect to the rear stop 7, so that they are not located in front of each other. one of the other, improving the locking of the device 1, in particular through the offset of the gravity point, the device 1 alone or under the action of the weight of a user.

The characteristic according to which the center of gravity of the device 1 is eccentric, can be obtained by the offset of said bar 3. In this case, visible on the figure 3 , said locking means 5 are integral with each end 4 of said bar 3 through an arm 8 of offset.

Preferably, said offset arm 8 extends so as to align said bar 3 above the front stop 6.

According to the preferred embodiment, visible on the figure 4 , said offset arm 8 is integrally connected to another arm 12 so as to form a triangular structure. The addition of such an arm 12 and this specific shape greatly improves the mechanical strength of the device 1.

According to another embodiment, said arm 12 can connect the offset arm 8 and the element 10 at any point. It then forms a smaller triangle.

According to the embodiments visible on the Figures 5 and 6 , said offset arm 8 and the element 10 may consist of a single piece, such as a bent plate 20, forming a circular arc so as to obtain the previously mentioned positioning.

In addition, the device 1 comprises gripping means, in particular in the form of handles 9, integral with said bar 3 and / or said locking means 5. More particularly, said handles 9 comprise removable fixing means at different points of the lug. frame. These removable fastening means can be obtained in particular by screwing, clipping or other.

According to the embodiments visible on the Figures 5 and 6 these removable fastening means are constituted by the specific interlocking of said handles with the bar 3. To do this, the latter has a polygonal section, including square, while each handle 9, at its attachment point, presents a complementary shape, such as female portion 24, so as to come to fit around the bar 3. This simple interlock ensures the maintenance of the handles 9, in particular when a weight is applied, while allowing to move them slidably along said bar 3.

Thus, they can thus be moved according to the exercises that the user wishes to practice, offering a very broad versatility in the muscular work possibilities proposed by the device 1 according to the invention.

In particular, said handles 9 may be inclined, in particular through said fastening means providing inclination. The latter makes it possible to keep the wrists in a natural position at the time of gripping, avoiding the usual broken positions of the existing devices.

Said inclination can be considered upwards or downwards, preferably downwards. This inclination can be double, namely downwards and deported forwards or backwards, preferably the front.

According to a preferred mode, but in no way limiting, said inclination can be carried out at an angle of between 11 and 13 degrees with respect to the longitudinal axis of the bar 3.

According to another embodiment, said handles 9 may be aligned with the ends 4 of the bar 3. To do this, said bar has twists in the vicinity of its ends 4 so that the latter have the aforementioned adequate inclination. This bending can be used to directly fix the handles 9 at the ends 4 of the bar 3, the latter also being attached to the offset arm 8.

Advantageously, said handles 9 comprise an element 11 T-shaped, provided removable or fixable at said bar. As visible on the figure 1 , this T-shaped element makes it possible to carry out exercises by keeping the legs, feet and calves at the level of the bar 3 of the device 1.

In addition, said device 1 adapts to any thickness of amount 2 of the splaying. To do this, it comprises means for adjusting the spacing between said stops 6 and 7.

According to the preferred embodiment, visible in the figures, the front stop 6 also comprises removable attachment means so as to be moved, reducing or increasing the distance with the rear stop 7, the latter remaining fixed or can also be mounted removable.

These fixing means may be in the form of orifices 13 formed through said offset arm 8. According to different embodiments, respectively visible on the Figures 3 and 4 these orifices 13 may be formed in at least one alignment, preferably two alignments, parallel to the axis of said offset arm 8.

According to another embodiment, visible on the Figures 5 and 6 said fastening means may be in the shape of at least one slide 21, in particular provided with notches, in order to adjust the spacing of the abutment 6 with respect to the abutment 7. At the desired spacing, the stop 6 is then blocked by said notches within said slide.

According to another embodiment, a simple compression, in particular obtained by screwing, makes it possible to hold said abutment 6 in place, in particular through the resistance conferred by the materials, in particular metal, for example at the level of the thread and the edges of said slide 21.

According to another embodiment, the element 10 on which the stops 6 and 7 are fastened can be provided telescopically, similarly to the bar 3, so that the front stop 6 is integral with a section of the element. while the rear stop 7 is secured to the other section.

According to another embodiment, not shown, the offset arm 8 and the element 10 can be made of a single piece, the latter having a curvature so as to confer the desired angle between said offset arm 8 and the element 10. Said curvature can be achieved by folding, then forming an elbow, or else through a single piece in the form of a circular arc.

In addition to being adaptable to any thickness of support, this characteristic makes it possible to choose the inclination of the device 1 for a better support or for particular exercises.

The device 1 allows to deport the grip by a user outside the frame of the doorway. This particularity facilitates in particular certain exercises requiring a working width greater than that of the frame of the door.

Of course, the invention is not limited to the examples illustrated and described above which may have variants and modifications without departing from the scope of the invention.
