Description

Title of the invention: REMOVABLE WALL STRUCTURE COMPRISING RETRACTABLE RAILS technical field

[0001] The present invention relates to the field of trellis ladders, more particularly to the field of trellises intended for domestic use. Previous technique

[0002] One of the most effective means of exercise is the use of a wall bar allowing for varied movements and uses such as warm-up, preparation for competition and corrective gymnastics.

[0003] The conventional configuration of the wall-mounted ladder is quite bulky, thus creating a growing demand for less bulky solutions, particularly for limited space inside a dwelling. Alternatives exist, including ladders with removable rungs designed for domestic use, usually fixed between two door jambs by screwing, as disclosed in the published utility model document DE 298 07 217 U.

[0004] However, the solution revealed in the utility model document offers opportunities for improvement aimed at increasing flexibility of use and reducing bulk. Indeed, the bars must be screwed in to remain in position on the uprights, which means that each disassembly systematically requires unscrewing, thus complicating the user experience. Description of the invention

[0005] The present invention aims to overcome at least one of the drawbacks of the aforementioned prior art. More particularly, the invention aims to provide a wall bar that offers great flexibility of use while occupying a small space.

[0006] To this end, the invention relates to a wall bar comprising: - two amounts, each provided with notches distributed along said amount; - bars capable of being retractably inserted into the notches of the uprights; remarkable in that each of the bars comprises at each of the two ends of said bar a cylindrical engagement portion of diameter D with two parallel flats at a distance M from each other; and Each notch comprises a circular notch bottom and an access path to the notch bottom with a width greater than or equal to the distance M and less than diameter D, so as to allow the two flats of the engagement portion to slide along the access path into the bottom of the notch followed by a rotation of the bar preventing the bar from coming out of the bottom of the notch, and vice versa.

[0007] Advantageously, the diameter D of each cylindrical engagement portion is greater than the distance M presented between the two parallel flats.

[0008] According to one embodiment, each of the bars has a cylindrical shape extending between the two engagement portions and having a diameter greater than or equal to the diameter D of said engagement portions.

[0009] According to one embodiment, the access path of each of the notches is horizontal or inclined towards the bottom of the notch and downwards, at an angle between 10° and 60° with respect to the horizontal, when the corresponding upright is vertical.

[0010] According to one embodiment, 0.5 D <M<0,9 D, préférentiellement 0,7 D<M<0,85 D

[0011] According to one embodiment, said trellis further comprising: - means of locking the bars in rotation within the notch bottoms.

[0012] According to one embodiment, the locking means are individual to each bar or common for several bars.

[0013] According to one embodiment, the locking means comprise a fork capable of engaging with the two flats of an engagement portion of one of the bars.

[0014] According to one embodiment, the fork includes a proximal part provided with an oblong hole mounted to slide with a transverse axis fixed to the corresponding upright.

[0015] According to one embodiment, at least one of the two uprights is intended to be fixed to a door frame or to a wall.

[0016] According to one embodiment, the fixing to the door frame is removable and includes at least one clamping wedge controlled by a pressure screw.

[0017] The features of the invention are advantageous in that the wall bars, equipped with removable rungs, offer remarkable flexibility in terms of use, arrangement, and installation. The retractable rungs are easy to mount and remove from the corresponding notches on the uprights, thus improving ergonomics and allowing the selection of a specific number of rungs, which facilitates balance exercises, for example, in a doorway.

[0018] Furthermore, the rapid dismantling of all the bars allows the door to be released quickly and easily. Retention is primarily ensured by the shape of the cylindrical engagement portions, each having two flat surfaces, and by the notch having a narrow access path leading to the bottom of the notch. This retention is also ensured secondarily by rotation-locking means, preferably corresponding to forks that further secure the keeping the bars in place so that they can be safely loaded with heavier weights, without risk of disengaging from their notches.

[0024] Fig. 1 represents a perspective view of an upright 4 of a trellis 2 according to the invention, in which said upright is intended to be mounted on an outside or inside side of a door frame, and more preferably on an outside side of the door frame.

[0025] The trellis 2 comprises two symmetrical uprights 4 arranged opposite each other and preferably in a vertical direction.

[0026] Each upright 4 comprises a series of notches 6 distributed along said upright 4, intended to receive lateral ends 8.1 of rungs 8, thus forming a wall ladder allowing its use as a means of physical exercise. The uprights 4 and / or the rungs 8 may be made of wood, aluminum, steel, or any other suitable material.

[0027] Preferably, each notch 6 comprises a notch bottom 6.2 of circular shape and an access path 6.1 to the notch bottom 6.2 which opens into said bottom 6.2.

[0028] The access path 6.1 preferably comprises a straight profile extending horizontally or inclined towards the bottom 6.2 and downwards relative to the horizontal. More preferably, the access path 6.1 is inclined, from a front face 4.1 of the corresponding upright 4, towards the bottom 6.2 and downwards, at an angle α with the horizontal, which is between 10° and 60°, and is even more preferably- typically between 20° and 50°.

[0029] The notches 6 pass completely through a thickness E of the corresponding upright 4. Advantageously, each bar 8 has a cylindrical shape centrally located between its two lateral ends 8.1, the latter having cylindrical engagement portions 9 visible according to figures 2 and 3.

[0030] Fig. 2 schematically illustrates a front view of one of the retractable rungs 8 of the wall bar 2 of Fig. 1.

[0031] Preferably, the cylindrical shape between the two lateral ends 8.1 preferably includes a diameter greater than or equal to the diameter D of the cylindrical engagement portion 9.

[0032] It can be seen that each lateral end 8.1 terminates in a terminal portion 8.2 having a diameter at least equal to, and preferably greater than, the diameter D of the adjacent cylindrical engagement portion 9. This terminal portion 8.2 ensures that the bar 8 is held in a lateral position after being inserted into the corresponding notch in the upright. The arrangement of the terminal portion 8.2 at each lateral end 8.1 remains optional.

[0033] Fig. 3 illustrates a cross-sectional view along axis AA passing transversely through the cylindrical engagement portion 9 at one end 8.1 of the bar 8 of Fig. 2.

[0034] The cylindrical engagement portion 9 advantageously comprises two parallel flats 9.1, each being separated from the other by a distance M less than a diameter D of said cylindrical engagement portion 9.

[0035] Preferably, the distance M is between half the diameter D and 0.9 D, and more preferably 0.7 D <M<0,85 D.

[0036] In this configuration, and with reference to Figures 1 to 3, the insertion of each bar 8 towards the bottom 6.2 of the notch 6 is done exclusively from the cylindrical engagement portion 9. Indeed, the access path 6.1 advantageously has a width W which is greater than or equal to the distance M between the two flats 9.1 and less than the diameter D. Thus, when the bar 8 is inserted, the two flats 9.1 slide preferentially towards the bottom 6.2 and downwards, along the access path 6.1 and with a restriction on the rotation of the bar 8, until the cylindrical engagement portion 9 is entirely disposed in the bottom 6.2 of the notch 6, to then allow (locally in the bottom 6.2) a rotation of said bar 8 around its main axis 8.3.

[0037] When the rotation of the bar 8 is approximately 90° after the insertion of the engagement portion 9 into the bottom of the notch 6.2, then the flats 9.1 are positioned perpendicular to the profile of the access path 6.1, which ensures that the bar 8 is held in position within the bottom 6.2 of the notch 6, thus restricting the extraction of the cylindrical engagement portion 9 from said bottom 6.2. Thus, the release of said engagement portion 9 of the bottom 6.2 is conditioned by a new rotation of the bar 8. Such a configuration advantageously corresponds to a primary means of maintaining the bar 8 in position in the corresponding notches 6.

[0038] In another embodiment of the invention, the wall bar 2 may also include a secondary means for holding the bar 8 in position, which may correspond to a means for locking said bar 8 in rotation in the corresponding base 6.2, and this preferably in addition to the primary holding ensured by means of the two flats 9.1.

[0039] The trellis 2 may include individual locking means for each rung 8 or common means for several rungs 8. For example, the locking means may include a pin that can pass completely through the cylindrical engagement portion 9 to insert radially into a corresponding hole in the bottom 6.2 of the notch within the upright 4. Alternatively, a rod may pass vertically and simultaneously through several rungs 8, linking them together to restrict their rotation and movement. Alternatively, a plate fixed to the upright can be positioned parallel and in direct contact with one of the two flats 9.1, thus preventing the corresponding bar from pivoting locally.

[0040] Preferably, each bar 8 may include one or more corresponding rotation locking means, including in particular a fork (visible in [Fig.4]) capable of engaging with the two flats 9.1 of the engagement portion 9 of the corresponding bar 8.

[0041] Fig. 4 schematically illustrates a front view of a post 4 of the wall bar 2 according to the invention, comprising means for locking 10 in rotation of the bars 8 in the bottoms 6.2 of notches, these locking means 10 corresponding preferably to forks 10 having a distal part 10.1 intended to be mounted astride the cylindrical engagement portion 9 in order to engage with the two flats 9.1.

[0042] In this [Fig.4], the engagement portions 9 of the two bars illustrated are represented by a cross-sectional view to facilitate reading the figure.

[0043] For this purpose, the fork 10 includes a proximal part 10.2 provided with a groove 10.3 or an oblong hole 10.3 mounted sliding with a transverse axis 12, which can correspond to a screw 12, fixed to the upright 4. This assembly is also visible in [Fig.5] along a lateral side of the upright 4.

[0044] In this configuration, and with reference to Figures 4 and 5, each fork 10 is guided in rotation around the transverse axis 12, as well as in translation by sliding of the proximal part 10.2 relative to said transverse axis 12, which allows to ensure that the fork 10 performs combined rotational and translational movements, the travels of which are illustrated by dotted arrows in [Fig.4].

[0045] Thus, during the insertion of the engagement portion 9 into the notch 6, the fork 10 can be moved aside manually, until said portion 9 is lodged in the bottom of the notch 6.2 and rotated 90°, to receive the fork 10 in order to ensure that the corresponding bar is held in place in the notch 6.

[0046] In another embodiment of the trellis of the invention, the uprights 4 are intended to be mounted on an inner side of the door frame. For this purpose, the rungs 8 are preferably without an end portion 8.2, and the ends 8.1 terminate laterally with the engagement portions 9.

[0047] The uprights 4 of the wall bar 2 of the invention can also be fixed to a wall in a traditional way, with retractable bars 8 and whose retention is more secure compared to the wall bars of the state of the art.

[0048] Advantageously, the uprights 4 can be mounted removably with the corresponding door frame, preferably by means of at least one clamping wedge (not shown) which can be controlled by a pressure screw, and which allows the corresponding upright to be clamped against an upper and / or lower edge of the corresponding door frame.

[0049] Alternatively, when the uprights 4 are fixed to the inside of the door frame, a lateral fixing bracket (not shown), preferably U-shaped, can clamp the assembly (an upright 4 with its corresponding frame). A screw controlled by a tightening knob can advantageously allow for quick manual tightening and / or loosening of the bracket. In this configuration, the trellis 2 can include several fixing brackets (for example, at least one bracket per upright 4) arranged at mid-height, or several brackets positioned at different heights of the assembly.

[0050] In another alternative not shown, only one of the two uprights of the wall bar can be pivotally mounted, by means of a hinge, to either a wall or a door frame, while the other upright has a wheel at its lower end allowing it to roll along the floor. Thus, the wall bar can be moved away from the corresponding wall or door, forming an angle of separation that can, for example, reach 90°. In this regard, a support arm can be positioned on one upper end of the other upright (in the vertical direction), connecting it to the corresponding wall or door frame to ensure the rigidity of the assembly. Such a configuration provides greater flexibility in the use of the wall bar, particularly in a living room where space is limited, thus facilitating its integration into space-constrained environments.
