Description

Title of the invention: Telescopic device for mounting two facing sides. Technical field of the invention

[0001] The technical field of the invention is that of telescopic devices, in particular those for mounting on two opposite faces, for example, of vertical posts. The invention relates to a telescopic device intended to be mounted on first and second faces facing each other, this telescopic device being, for example, intended for mounting a sports accessory. Prior art

[0002] There are known different ways of mounting a so-called "exercise" device allowing exercises to be performed, this mounting being done on a door frame, also called a door frame.

[0003] According to one practice, an exercise device is used comprising a telescopic bar that exerts forces in opposite directions, via pads arranged at its opposite longitudinal ends, on opposite uprights of the frame. This solution is unsafe because if the length of the telescopic bar is incorrectly adjusted, the forces may be insufficient: the telescopic bar may slip between the two uprights, causing the user to fall, for example, if they are pulling on the exercise device.

[0004] According to another practice, it is known to use an exercise device having a support element bearing against a cross member of the frame on one face of the frame and two support members bearing against the two uprights of the frame on a second face of the frame opposite its first face. A problem with this other practice is that if the user applies excessive force during pulling, this can remove the support on the cross member of the frame, causing the exercise device to fall.

[0005] Both types of exercise devices described above have the disadvantage of being unsafe. Object of the invention

[0006] The present invention aims to make the use of a telescopic device to be mounted between two opposite faces safer.

[0007] To this end, the invention relates to a telescopic device intended to be mounted on first and second faces opposite each other, the telescopic device comprising: • a first support member and a second support member opposed and separated by a separation distance, the first support member and the second support member being intended to bear respectively against one of the first face and the second face, and against the other of the first face and the second face; • a telescopic system comprising a first telescopic bar and a second telescopic bar, at least the first telescopic bar being connected to the first support member, said telescopic system being configured to selectively adopt: • an adjustment configuration allowing a variation in the length of the first telescopic bar, resulting in an adjustment of the separation distance, and allowing a variation in the length of the second telescopic bar; • a locking configuration in which the length of the first telescopic bar and the length of the second telescopic bar remain fixed; • a connecting element mounted to the first and second telescopic bars; • an adjustment device configured to, in the locking configuration of the telescopic system, move the second support member in order to adjust the separation distance.

[0008] In general, such a telescopic device can be installed between and in contact with the first and second faces in a secure and intuitive manner for the following reasons: • the presence of two telescopic bars allows the support forces to be distributed on the first and second faces; • the telescopic system allows for an initial length adjustment of the telescopic device, this length being measured between two faces oriented in opposite directions of the first and second support members; • The adjustment device allows fine adjustment to exert appropriate support forces respectively against the first face and against the second face to mount the telescopic device between these first and second faces, or allows the length of the telescopic device to be reduced between said two faces oriented in opposite directions in order to remove the telescopic device from the first and second faces.

[0009] The telescopic device may further include one or more of the following features.

[0010] According to a feature of the telescopic device, the second telescopic bar is connected to the first support member, the telescopic device being configured so that, in the adjustment configuration, the lengths of the first and second telescopic bars vary simultaneously.

[0011] This allows for simultaneous adjustment of the first and second telescopic bars connected to the same first support member. Furthermore, it increases the bearing surface of the first support member for improved retention between the first and second faces.

[0012] According to a feature of the telescopic device, the adjustment device includes a plate attached to the first and second telescopic bars, and an adjustment mechanism for the spacing distance of the plate relative to the second support member.

[0013] The plate thus serves as an interface between the telescopic system and provides a support point for the adjustment mechanism.

[0014] According to a feature of the telescopic device, the adjustment mechanism comprises: • a rod comprising a thread, a first longitudinal end and a second longitudinal end, the second longitudinal end of the rod being connected to the second support member, the rod passing through the plate; • an element engaged on the net; the adjustment mechanism being configured so that the adjustment of the spacing distance is implemented by a relative displacement between the rod and the element engaged on the thread, the telescopic device comprising a manual actuating member and being configured so that the relative displacement is induced by actuating the manual actuating member.

[0015] This allows a force to be exerted via human actuation of the manual actuation member to allow the telescopic device to hold by friction on the first and second faces for example on a door frame.

[0016] According to a feature of the telescopic device, the telescopic device is such that: • the threaded rod is fixed relative to the second support member; • the element engaged on the thread is arranged between the plate and the second support member, and is configured to be pressed against the plate when the first support member is pressed against one of the first and second faces and the second support member is pressed against the other of the first and second faces; • The manual actuation device allows the engaged element on the thread to be moved along the rod.

[0017] Such an adjustment mechanism is simple to use, the element engaged on the thread (when it is in contact with the plate) allows the distance of separation of the plate relative to the second support member to be defined when the first and second support members are stressed towards each other.

[0018] According to a feature of the telescopic device, the telescopic device is such that • the rod is mounted to the second support member so as to be free to rotate relative to the second support member; • the element engaged on the thread is a hole in the plate; • The manual actuation device is designed to selectively rotate the rod: • according to a first direction of rotation inducing a bringing of the second support member closer to the plate; • according to a second direction of rotation inducing a distancing of the second support member from the plate.

[0019] This allows the separation distance to be adjusted appropriately while maintaining the second support member, and therefore the spacing distance from the plate since the rod is screwed into the plate.

[0020] According to a feature of the telescopic device, the second support member is mounted relative to the plate by means of a sliding connection.

[0021] This allows its degree of freedom to be fixed in order to ensure easy mounting of the telescopic device on the first and second faces.

[0022] According to a feature of the telescopic device, the telescopic device comprises a first guide rod and a second guide rod, each extending from the second support member, the plate comprising a first guide in which the first guide rod is engaged and a second guide in which the second guide rod is engaged, the first guide rod having a longitudinal end housed in the first telescopic bar and the second guide rod having a longitudinal end housed in the second telescopic bar.

[0023] The first and second guide rods are therefore in line respectively with the first telescopic bar and the second telescopic bar, which allows the adjustment device to be in line with these first and second telescopic bars.

[0024] According to a feature of the telescopic device, each of the first and second telescopic bars comprises a hollow body forming a sliding guide and a sliding part engaged in the hollow body, the sliding of said sliding part relative to said hollow body being inhibited in the configuration locking, preferably by means of a clamping ring, said sliding part comprising a longitudinal end connected to the adjustment device.

[0025] In this way, the adjustment device is arranged in line with the first and second telescopic bars, which makes the telescopic device compact and allows for easy initial length adjustment, then adjustment to mount the telescopic device securely on the first and second faces via forces directed in opposite directions.

[0026] According to a feature of the telescopic device, each of the first and second telescopic bars includes a sliding element engaged in its hollow body opposite the sliding part engaged in its hollow body, said sliding element including a longitudinal end connected to the first support member, the sliding of said sliding element relative to said hollow body being inhibited in the locking configuration, preferably by means of a clamping collar.

[0027] This allows the connecting element to be centered between the first and second support members in order to obtain better ergonomics of use and better distribution of the forces induced by traction applied at the level of the connecting element when the telescopic device is mounted on the first and second faces.

[0028] According to a feature of the telescopic device, the connecting element is arranged between the first telescopic bar and the second telescopic bar, the telescopic device comprising: • the first fixing brackets extending from the first telescopic bar and staggered between the first support member and the second support member; • second fixing lugs extending from the second telescopic bar and staggered between the first support member and the second support member; • assembly components; and, for each leg chosen from the first and second fixing legs, said leg is engaged in the connecting element and passed through by one of the assembly members cooperating with the connecting element in order to ensure a fixing of the connecting element to said leg.

[0029] This allows for efficient fixing of the connecting element.

[0030] According to a feature of the telescopic device, the telescopic device comprises: • a first clamping member configured to exert a clamping force between a bearing surface of the first clamping member and a lateral face of the first support member; and / or • a second clamping member configured to exert a clamping force between a bearing surface of the second clamping member and a lateral face of the second support member.

[0031] This allows additional support of the telescopic device, for example to a door frame, for example by clamping a shoulder of the frame in the manner of a clamp.

[0032] The invention also relates to a device for physical activity comprising the telescopic device as described and a sports accessory attached to the telescopic system.

[0033] Thus, the first and second sides can be used to mount the sports accessory and allow for physical activity, including pulling up.

[0034] The device for physical activity may be such that the sports accessory is a beam equipped with handholds.

[0035] This allows one to engage in a sporting activity consisting of training for a subsequent climbing activity, for example indoors or outdoors.

[0036] Other advantages and features may become apparent from the detailed description that follows. Brief description of the drawings

[0046] In this description, "between two values" means a range of values ​​including said two values.

[0047] The invention relates to a telescopic device 100 intended to be mounted on first and second faces 1001, 1002 opposite each other. These first and second faces 1001, 1002 are in particular vertical.

[0048] The device 100 is said to be “telescopic” because its dimension, in particular its length, can be adjusted to allow it to exert opposing forces on the first and second faces 1001, 1002, resulting in the telescopic device 100 being held in position relative to these first and second faces 1001, 1002 and in particular above a ground S as shown by way of example in [Fig.1].

[0049] Figure 1 shows an example of the telescopic device 100 mounted on a door frame 1000. Thus, the first and second faces 1001, 1002 are delimited respectively by a first jamb 1003 of the door frame 1000 and a second jamb 1004 of the door frame 1000.

[0050] The example of mounting on the door frame 1000 is illustrative in the sense that the telescopic device 100 can be mounted at any type of opening or passage such as for example a door opening to which a door frame is mounted, the frame 1000 itself ([Fig.1]), or even two opposite walls of a corridor.

[0051] Figures 2 to 4 illustrate a first embodiment of the telescopic device 100, and figures 5 and 6 illustrate a second embodiment of the telescopic device 100.

[0052] The telescopic device 100 comprises, as illustrated for example in Figures 1, 2 and 5, a first support member 101 and a second support member 102 opposed and separated by a separation distance dl. The first support member 101 and the second support member 102 are intended to bear against one of the first face 1001 and the second face 1002, and against the other of the first face 1001 and the second face 1002, respectively (see in particular [Fig. 1] where this is the case).

[0053] Each of the first and second support members 101, 102 may include a support 101a, 102a, preferably rigid so as not to deform under the operating conditions of the telescopic device 100, and a friction element 101b, 102b intended to form a bearing surface in contact with the corresponding first face 1001 or second face 1002. In particular, the length of the telescopic device 100 is measured between the bearing surfaces of the two friction elements 101b, 102b.

[0054] The supports 101a, 102b can be made of metal.

[0055] The fictional elements 101b, 102b can be made of rubber or TPU (abbreviation for "thermoplastic polyurethane" in English, in French thermoplastic polyurethane). Each of the fictional elements 101b, 102b can be such that its bearing surface includes raised patterns to accentuate friction in order to ensure satisfactory retention between the first and second faces 1001, 1002.

[0056] The telescopic device 100 includes a telescopic system 103 comprising a first telescopic bar 104 and a second telescopic bar 105, for example each made of metal.

[0057] In fact, the first telescopic bar 104 and the second telescopic bar 105 can each have a length which can be adapted and which can vary between a minimum length and a maximum length.

[0058] For example, the minimum length can be 650 mm and the maximum length 1230 mm. These lengths are particularly suitable for mounting the telescopic device 100 on the frame 1000, where the spacing between the uprights typically varies between 730 mm and 830 mm and can extend up to 930 mm. This illustrative example can certainly be adapted; indeed, depending on the intended use, i.e., the distance between the first and second faces 1001, 1002, the minimum and maximum lengths of the first and second telescopic bars 104, 105 can be adjusted for manufacturing the telescopic device 100.

[0059] These first and second telescopic bars 104, 105 can each have any type of cross-section taken orthogonally to their respective extension direction, adapted to the function; this cross-section can be circular or square. For example, in Figures 2 and 5, the first and second telescopic bars 104, 105 are tubular.

[0060] At least the first telescopic bar 104 is connected, for example fixed, to the first support member 101.

[0061] For example, a longitudinal end 104a of the first telescopic bar 104 is welded to the support 101a of the first bearing member 101 as shown in [Fig. 4]. In particular, the support 101a of the first bearing member 101 may include a projecting member engaged in the first bar 104 to improve the attachment of the first telescopic bar 104 to the first bearing member 101.

[0062] The telescopic system 103 is configured to selectively adopt: • an adjustment configuration allowing a variation in the length of the first telescopic bar 104, resulting in an adjustment of the separation distance dl, and allowing a variation in the length of the second telescopic bar 105; • a locking configuration in which the length of the first telescopic bar 104 and the length of the second telescopic bar 105 remain fixed.

[0063] The telescopic device 100 includes a connecting element 106 mounted to the first and second telescopic bars 104, 105, for example by fastening with screws. Thus, the first and second telescopic bars 104, 105 are held together, which facilitates the handling of the telescopic device 100, particularly during its installation between the first and second faces 1001, 1002.

[0064] The connecting element 106 can be a support element, for example made of wood, intended for mounting a sports accessory 126 ([Fig.l]) or can be directly the sports accessory 126.

[0065] The telescopic device 100 includes an adjustment device 107 configured to, in the locking configuration of the telescopic system 103, move the second support member 102 in order to adjust the separation distance dl.

[0066] Thus, the telescopic device 100 can have two types of adjustment, a first coarse adjustment to adapt it to the separation distance of the first and second faces 1001, 1002 and a fine adjustment, for example incremental, which can adjust the separation distance of the first and second support members 101, 102 in order to exert suitable opposing forces on the first and second faces 1001, 1002.

[0067] The purpose of these two types of adjustment is to allow quick and secure mounting of the telescopic device 100 to the first and second faces 1001, 1002.

[0068] For example, the adjustment device 107 is configured to allow an adjustment range of 80 mm. In other words, with the telescopic system 103 at a fixed length, the separation distance dl can vary over 80 mm between the first position of the second support member 102 and a second position of the second support member 102 relative to the first support member 101.

[0069] Preferably, and as illustrated in particular in Figures 2 and 5, the second telescopic bar 105 is connected to the first support member 101. For example, a longitudinal end 105a of the second telescopic bar 105 is welded to the support 101a of the first support member 101. This allows, in particular, for the adjustment of the first and second telescopic bars 104, 105 to be simultaneous, at least on the side of the first support member 101 that is integral with the first and second telescopic bars 104, 105. Therefore, the telescopic device 100 is preferably configured so that, in the adjustment configuration, the lengths of the first and second telescopic bars 104, 105 vary simultaneously.

[0070] The fact that the first support member 101 connects the first and second telescopic bars 104, 105 further allows for the presence of a bearing surface of its friction element 101b exhibiting an elongation along the direction of separation of the first and second telescopic bars 104, 105: this makes it possible to increase the friction with the first face 1001 or the second face 1002, improving the retention of the telescopic device 100 relative to the first and second faces 1001, 1002, particularly when a user performs pull-ups using the telescopic device 100. Therefore, the bearing surface of the first support member 101 (delimited where applicable by its friction element 101b) can exhibit an elongation greater than the spacing distance of the first and second telescopic bars 104, 105, thus allowing good support and distribution of forces when the telescopic device 100 is mounted on the first and second faces 1001, 1002.

[0071] The adjustment device 107 may include a plate 108 attached to the first telescopic bar 104 and preferably to the first and second telescopic bars 104, 105, and a mechanism 109 for adjusting a distance d2 of the plate 108 from the second support member 102.

[0072] In particular, the plate 108 is welded / fixed to the first and second telescopic bars 104, 105 via their respective longitudinal ends 104b, 105b opposite the first support member 101 (Figures 4 and 5). In particular, the plate 108 may include projecting members engaged respectively in the first telescopic bar 104 and in the second telescopic bar 105 to improve their attachment to the plate 108.

[0073] In combination with the embodiment in which the first and second telescopic bars 104, 105 are also connected / welded to the first support member 101, it is clear that, in the adjustment configuration, the adjustment of the length of the first and second telescopic bars 104, 105 is done simultaneously because the extension or reduction of one causes the extension or reduction of the other via their mechanical links to the plate 108 and to the first support member 101.

[0074] As mentioned above, one purpose of the adjustment mechanism 109 is to allow fine adjustment of the separation distance dl (in particular by adjusting the spacing distance d2). To this end, there is a need to implement a reliable solution that allows for easy maintenance of the fine adjustment.

[0075] To this end, the adjustment device 107 and, where applicable, the adjustment mechanism 109, may include a helical linkage to implement an adjustment / setting of the spacing distance d2. A helical linkage has the advantage of allowing incremental adjustment depending on the pitch of a thread in the helical linkage and the advantage of maintaining the adjustment / setting when the helical linkage is not subjected to rotational movement.

[0076] According to one embodiment of the adjustment device 107, the adjustment mechanism 109 may comprise: • a rod 110 comprising a thread 111 (also called a thread), a first longitudinal end 110a (notably visible in Figures 2 to 6) and a second longitudinal end 110b (visible in [Fig. 4]), the second longitudinal end 110b of the rod 110 being connected, for example welded, to the second support member 102, the rod 110 passing through the plate 108; • an element 112 engaged on the net 111; the adjustment mechanism 109 being configured so that the adjustment of the spacing distance d2 is / is implemented by a relative displacement between the rod 110 and the element 112 engaged on the thread 111. The telescopic device 100, or more particularly the adjustment device 107, includes a manual actuation member 113 and is configured so that the relative displacement is / is induced by actuation of the manual actuation member 113.

[0077] Thus, the fineness of the fit can depend on the pitch of the thread 111 of the rod 110 obtained in particular by threading.

[0078] In particular, the adjustment device 107, and more particularly the adjustment mechanism 119, allows an incremental adjustment of the separation distance dl, which is notably dependent on the pitch of the thread 111.

[0079] By "element 112 engaged on the thread 111 of the rod 110", it is understood that the element 112 has a complementary thread (for example obtained by tapping) to the thread 111 of the rod 110 which is then screwed into the element 112 engaged on the thread 111.

[0080] In particular, the axis of the rod is in a direction of length adjustment of the telescopic device 100 (in particular parallel to the first and second telescopic bars 104, 105), this allows the thread 111 of the rod to oppose a change in the length of the telescopic device 100 as long as a rotational movement between the element 112 and the rod 110 is not implemented manually via the manual actuation member 113.

[0081] Figures 2 and 3 show a first embodiment of the adjustment mechanism 109. In particular, the rod 110 can be fixed relative to the second support member 102, notably because it is welded to it via one of its longitudinal ends. The element 112 engaged on the thread 111 is arranged between the plate 108 and the second support member 102. The element 112 engaged on the thread 111 is configured to be pressed against the plate 108 when the first support member 101 is pressed against one of the first and second faces 1001, 1002 and the second support member 102 is pressed against the other of the first and second faces 1001, 1002. The manual actuation member 113 allows the element 112 engaged on the thread to be moved (in particular to be rotated) along the rod 110 to obtain the relative displacement.

[0082] Thus, the element 112 engaged on the thread 111 can be a nut, for example hexagonal and the manual actuation member 113 can be a key complementary to the nut.

[0083] The telescopic device 100 can be configured so that the manual actuation member 113 is free to rotate 360 ​​degrees, which makes it easy to move the element 112 engaged on the thread 111 in one direction or another along the rod 110.

[0084] Alternatively, the manual operating member 113 may be a ratchet wrench whose direction of use can be selected manually. This may be advantageous when the manual operating member 113 cannot rotate 360 ​​degrees without obstruction.

[0085] In particular, it is understood here that the length of the telescopic device 100, and in particular the separation distance dl and the spacing distance d2, are given when the element 112 engaged on the thread 111 is pressed against the plate 108.

[0086] The nut forming the element 112 engaged on the thread 111 can be a locking nut, this facilitates its rotation, especially when the manual actuation element 113 is the ratchet wrench which will require some resistance to be raised / turned in a direction opposite to its direction of rotation in contact with the nut (i.e. driving the nut).

[0087] Figures 5 and 6 show a second embodiment of the adjustment mechanism 109 in which the rod 110 can be mounted on the second support member 102 so as to be free to rotate relative to the second support member 102. The element 112 engaged on the thread 111 is a hole in the plate 108 having a thread (i.e., the hole is threaded). In other words, the rod 110 is screwed into the plate 108. The manual actuating member 113 is intended to selectively rotate the rod 110: • according to a first direction of rotation inducing a closer approach of the second support member 102 relative to the plate 108; • according to a second direction of rotation inducing a distancing of the second support member 102 from the plate 108.

[0088] For example, the manual actuation member 113 can be a crank fixed to the rod 110 so that the rotation of the crank causes the rod 110 to pivot about its longitudinal axis.

[0089] According to another example, a nut 115 ([Fig. 6]) is welded to the rod 110, specifically on the side of the second support member 102. The manual actuation member 113 can then be a complementary wrench to the nut 115.

[0090] The telescopic device 100 can be configured so that the manual actuating member 113 is free to rotate 360 ​​degrees, which makes it easy to rotate the nut 115 and thus the rod 110. Alternatively, the manual actuating member 113 can be a ratchet wrench whose direction of use can be manually selected. This can be advantageous when The manual actuation component 113 cannot perform a 360-degree rotation without hindrance.

[0091] According to the second embodiment of the adjustment mechanism 109, the rotational freedom of the rod 110 relative to the second support member 102 can be implemented according to a pivot joint, for example using bearings integrated into the second support member 102.

[0092] Preferably, the second support member 102 is mounted relative to the plate 108 by means of a sliding connection. This makes it possible to constrain the movement of the second support member 102 while preventing its rotation: only its translation will be permitted. This is particularly suitable when the second support member 102 must cooperate with one of the uprights 1003, 1004 of the frame 1000. Furthermore, this makes it easy to maintain opposing supports for the first and second support members 104, 105 in order to obtain a better distribution of forces during the mounting of the telescopic device 100 on the first and second faces 1001, 1002.

[0093] In order to ensure proper movement of the second support member 102, the telescopic device 100 may include a first guide rod 116 and a second guide rod 117 extending each from the second support member 102 (Figures 2 to 6), and in particular each welded to the second support member 102.

[0094] In this case, the plate 108 comprises (as shown for example in [Fig. 4]) a first guide 118 in which the first guide rod 116 is engaged and a second guide 119 in which the second guide rod 117 is engaged. These first and second guides 118, 119 cooperate in particular with the first and second guide rods 116, 117 according to the sliding connection as described above so that the first and second support members 101, 102 remain opposed and in particular crossed by a plane intersecting, preferably orthogonally, the bearing surfaces of the friction elements 101b, 102b and in particular parallel to the length adjustment direction of the telescopic device 100.

[0095] The first guide rod 116 has a longitudinal end 116a housed in the first telescopic bar 104, and the second guide rod 117 has a longitudinal end 117a housed in the second telescopic bar 105. This allows the second support member 102 to be in continuity with the first and second telescopic bars 104, 105, since the first and second guide rods 116, 117 ensure continuity with the first and second telescopic bars 104, 105.

[0096] The first and second guides 118, 119 can each form a projection from a part of the plate 108 and be engaged in, and in particular welded to, respectively the first telescopic bar 104 and the second telescopic bar 105.

[0097] A preferred embodiment of the telescopic system 103 is now described. In particular, each of the first and second telescopic bars 104, 105 may comprise a hollow body 1041, 1051 forming a sliding guide and a sliding portion 1042, 1052 engaged in the hollow body 1041, 1051, the sliding of said sliding portion 1042, 1052 relative to said hollow body 1041, 1051 being inhibited in the locking configuration, preferably by means of a clamping ring 1043, 1053, said sliding portion 1042, 1052 comprising a longitudinal end connected to the adjustment device 107, this end being in particular: • for the first telescopic bar 104, the longitudinal end 104b of the first telescopic bar 104 opposite its longitudinal end 104a connected to the first support member 101; • for the second telescopic bar 105, the longitudinal end 105b of the second telescopic bar 105 opposite its longitudinal end 105a connected to the first support member 101.

[0098] For example, the longitudinal end of the corresponding sliding part 1042, 1052 is welded to the adjustment device 107 and more particularly to the plate 108.

[0099] In particular, each of the first and second telescopic bars 104, 105 may include a sliding element 1044, 1054 engaged in its hollow body 1041, 1051 opposite the sliding portion 1042, 1052 engaged in its hollow body 1041, 1051, said sliding element 1044, 1054 comprising a longitudinal end connected (in particular welded) to the first support member 101 (where applicable, this end is the longitudinal end 104a of the first telescopic bar 104 connected to the first support member 101, or is the longitudinal end 105a of the second telescopic bar 105 connected to the first support member 101), the sliding of said sliding element 1044, 1054 relative to said hollow body 1041, 1051 being inhibited in the configuration locking, preferably by means of a 1045, 1055 clamping collar.

[0100] The clamping collars 1045, 1055 and / or the clamping rings 1043, 1053 can each be manually operated and of the same type, for example by means of a crank which it integrates, or operated requiring the use of a tool such as an Allen key.

[0101] The connecting element 106 can be arranged between the first telescopic bar 104 and the second telescopic bar 105. In this case, the telescopic device 100 can comprise, as illustrated for example in Figures 2, 5 and 7 (in [Fig. 7], the connecting element 106 is removed for clarity): • the first fixing legs 120 extending from the first telescopic bar 104 and staggered between the first support member 101 and the second support member 102; • second fixing legs 121 extending from the second telescopic bar 105 and staggered between the first support member 101 and the second support member 102; • assembly parts 123. For each leg selected from the first and second mounting legs 120, 121, said leg is engaged in the connecting element 106 and passed through by one of the assembly members 123 cooperating with the connecting element 106 in order to secure the connecting element 106 to said leg. This allows each of the first and second mounting legs 120, 121 to be fixed to the connecting element 106 by means of one of the assembly members 123.

[0102] The first fixing legs 120 can be welded to the first telescopic bar 104, in particular to its hollow body 1041.

[0103] The second fixing legs 121 can be welded to the second telescopic bar 105, in particular to its hollow body 1051.

[0104] The assembly parts 123 can be screws.

[0105] In particular, for good alignment of the connecting element 106 between the first telescopic bar 104 and the second telescopic bar 105, the connecting element 106 may include opposite edges shaped to conform at least locally to the shape of the corresponding first or second telescopic bar 104, 105.

[0106] It has been mentioned above that the first and second support members 101, 102 allow opposing forces to be exerted on the first and second faces 1001, 1002. When these first and second faces 1001, 1002 are those of the frame 1000, it is possible to benefit from additional support by using additional faces of the frame resulting from shoulders 1005, 1006 provided in the uprights of the frame 1000 ([Fig.1]), these additional faces forming an angle with the first and second faces 1001, 1002. In particular, these additional faces of the frame are orthogonal to the first and second faces 1001, 1002.

[0107] For this purpose, the telescopic device 100 may include: • a first clamping member 124 configured to exert a clamping force between a bearing surface 124a of the first clamping member 101 and a lateral face of the first support member 101 (in particular facing said bearing surface 124a of the first clamping member 124); and / or • a second clamping member 125 configured to exert a clamping force between a bearing surface 125a of the second clamping member 125 and a lateral face of the second 102 support member (in particular turned towards said support bearing 125a of the second clamping member 125). Thus, the first clamping member 124 can form, with the first support member 101, a clamp configured to exert a clamping force in a direction forming an angle, in particular a right angle, with the extension direction of the telescopic system 103. Furthermore, the second clamping member 125 can form, with the second support member 102, a clamp configured to exert a clamping force in a direction forming an angle, in particular a right angle, with the extension direction of the telescopic system 103.

[0108] The connecting element 106 may include a cavity 114 suitable for receiving the rod 110 depending on the separation distance dl, as shown for example in [Fig. 4]. This allows for a wide range of adjustment of the telescopic device 100, in particular by allowing its length to be reduced to a minimum without interference from the rod 110, which would otherwise abut against the connecting element 106.

[0109] According to a particular embodiment, the first and second members 101, 102 have bearing surfaces of identical surface area

[0110] The embodiments shown depict two single opposing support members 101, 102. However, it is entirely possible to provide two independent first support members, respectively connected to the first telescopic bar 104 and the second telescopic bar 105, and two independent second support members opposite the first support members, for example, associated with the same adjustment mechanism 109 allowing them to be moved simultaneously, or with two independent adjustment mechanisms allowing each of the second support members to be moved independently. In the case of two first support members, the first and second telescopic bars may be linked to each other to allow simultaneous length adjustment, or not linked to allow independent length adjustment.

[0111] The invention also relates to a device 1000 for physical activity comprising a telescopic device 100 as described and a sports accessory 126 attached to the telescopic system 103.

[0112] This sport accessory 126 can be the connecting element 106 (not shown) or be a sport accessory 126 mounted on the connecting element 106 (see for example [Fig.1]).

[0113] The sports accessory 126 may be a beam, for example made of wood, equipped with grips 127. The grips 127 are intended in particular to be grasped by a user so that he can perform exercises such as pull-ups.

[0114] The telescopic device 100 finds an industrial application in the field of sport, in particular by allowing two opposite faces to be functionalized by installing the telescopic device 100 there so that it is held there.
