FIG. 7 shows a right rear perspective view of the base of the play structure ofFIGS. 1a to 4 b, with the lower element in an upright position. - In relation with these figures, a play structure is described hereinbelow, in particular for the practice of basketball.
- The play structure comprises a
base 1 that rests on the ground and at least one element 2 mounted in rotation on said base between a folded down position and an upright position in order for said structure to be used. Alternatively, the element 2 can be mounted telescopically on thebase 1 between a retracted position and an upright position for the use of the structure. - In the embodiment shown, the structure comprises a lower element 2 mounted in rotation on the
base 1 between a folded down position and an upright position, as well as an upper element 3 on which is mounted abasketball backboard 4 and which is mounted in rotation on an upper end of said lower element between a folded position and a deployed position. - As such, the structure can be arranged between a storage position, wherein the lower 2 and upper 3 elements are respectively in folded down and folded position, and a position of use, wherein the lower 2 and upper 3 elements are respectively in upright and deployed position, and this by successively switching the lower element 2 from the folded down position to the upright position, then the upper element 3 from the folded position to the deployed position.
- Alternatively, the structure can include a single element 2 having a lower end mounted in rotation on the base, as well as an upper end carrying a
basketball backboard 4. - The
base 1 comprises a central frame 5 on which the lower element 2 is mounted in rotation, as well aswheels 6 mounted on the frame 5 in order to allow for the movement of the structure. In relation withFIG. 6 , thewheels 6 each include a hub integral with the central frame 5, said hubs being arranged in order to allow thewheels 6 to rotate independently one from the other. - In particular, at least some of the
wheels 6 are arranged in order to be able to be filled with a ballast material, for example water or sand, in order to form a counterweight to the lower element 2 in upright position. To do this, the wheels that can be filled 6 each include a cylindrical reservoir on the periphery of which an opening 7 is arranged in order to allow them to be filled with such a ballast material. - For a good distribution of the weight, the wheels that can be filled 6 are distributed in pairs on either side of the central frame 5. In relation with the figures, the
base 1 comprises in particular three pairs of wheels that can be filled 6 distributed on either side of the central frame 5. - Moreover, the axis of revolution of the reservoirs extends horizontally and perpendicularly to the longitudinal axis of the frame 5, so that the
base 1 can be moved by rolling said reservoirs on their periphery. - With regards to the mounting of the lower element 2, the central frame 5 has a front end on which said lower element is mounted in rotation. As such, in order to arrange the play structure in position of use, the user firstly switches the lower element 2 from the folded down position (
FIG. 1 ) to the upright position (FIG. 2 ) by pivoting it in relation to the front end of the central frame 5. - In order to facilitate the arrangement of the structure in position of use, said structure comprises a system for assisting in the moving of the lower element 2 in upright position. Such a system for assisting is all the more so desirable in that the user, by moving the lower element 2 in upright position, must not only manipulate said lower element, but also the upper element 3 arranged in folded position on said lower element, as well as the
basketball backboard 4 mounted on said upper element, which can prove to be constraining in light of the total weight of the whole. - In relation with the figures, the system for assisting comprises a linking arm 8 that has a first end mounted in rotation on the lower element 2, as well as a second end mounted in translation on the
base 1, for example on a rail formed for this purpose on the central frame 5. - Moreover, the system for assisting comprises spring means 9 mounted on the central frame 5 on either side of the second end of the linking arm 8, said spring means being arranged to actuate the translation of the linking arm 8 with respect to the central frame 5, in such a way as to assist the moving of the lower element 2 in upright position.
- To do this, the spring means 9 are blocked in constrained position when the lower element 2 is in folded down position. For example, the spring means 9 can be compression—respectively traction—springs which are contracted—respectively stretched—when the lower element 2 is in folded down position, in such a way as to accompany the translation of the linking arm 8 by expanding—respectively by contracting—to their rest position.
- In order to ensure safety, whether during the use of the structure or during its arrangement in position of use, said structure further comprises a system for blocking 10 the lower element 2 in upright position, in order to prevent said lower element from tipping over in an untimely manner in folded down position.
- In particular, the system for blocking 10 comprises means for blocking the linking arm 8 in translation and/or in rotation, in
particular studs 11 carried by one among said linking arm and the lower element 2, said studs being intended to be blocked in a device for receiving carried by the other among the lower element 2 and the linking arm 8 when said lower element is in upright position. - In relation with the figures, the device for receiving comprises a
plate 12 which is mounted in rotation on the lower element 2 and which has a slot for blockingstuds 11 mounted on the linking arm 8. - As such, during the deployment of the lower element 2 in upright position, the
studs 11 are positioned in the slot for blocking of theplate 12, in such a way as to activate the system for blocking 10. - Moreover, in order to arrange the structure in storage position, the
plate 12 is actuated manually in rotation in order to unblock thestuds 11 from the slot, in such a way as to be able to move the linking arm 8 in translation and as such allow for the arrangement of the lower element 2 in folded down position. - In relation with
FIG. 7 , the system for blocking 10 also comprises ahook 13 mounted in rotation on the linking arm 8 and intended to be manually hooked to a front transversal bar 14 mounted above the rail on the central frame 5, so as to prevent the translation of said linking arm in said rail and as such contribute to the blocking of the lower element 2 in upright position. - In order to provide further stability to the structure when it is arranged in position of use, the lower element 2 is arranged to rest on the ground in upright position, which makes it possible to prevent the tipping over of said structure in said position of use.
- To do this, the lower element 2 comprises two
legs 15 mounted on either side of its lower end and intended to rest on the ground when said lower element is in upright position. As such, thelegs 15 provide better stability to the structure by preventing in particular the tipping over thereof on the sides, and this in combination with thebase 1 which forms a counterweight in order to prevent it from tipping over towards the front or towards the rear. Thelegs 15 also make it possible to prevent thebase 1 from rolling when the lower element 2 is in upright position, in particular during the use of the play structure or during its arrangement in position of use. - Once the lower element 2 is in upright position, the user can arrange the play structure in position of use by switching the upper element 3 from the folded position (
FIGS. 2 ), in which said upper element is arranged against said lower element, to the deployed position (FIGS. 3 ), and this by manually pivoting said upper element in relation to the upper end of the lower element 2 on which it is mounted in rotation. - The upper element 3 comprises a free end on which the
basketball backboard 4 is mounted, said backboard comprising aboard 4 a and ahoop 4 b on which a net can be hung. - In order to limit the encumbrance of the play structure when it is arranged in storage position, the
basketball backboard 4 can be arranged in such a way as to be folded back against the upper element 3 which is itself arranged against the lower element 2 when arranged in folded position. To do this, thebasketball backboard 4 can be mounted in rotation on the free end of the upper element 3. - Moreover, the
hoop 4 b can be mounted in rotation on thebackboard 4 so as to be folded back against theboard 4 a when the play structure is in storage position. Alternatively, thehoop 4 b can be reversibly mounted on thebackboard 4 by means of a system without a tool, in order to allow the user to easily dismount said hoop when he wishes to store the play structure. - In particular, as shown in
FIGS. 3 and 4 , the upper element 3 comprises two pairs of upper 3 a and lower 3 b parallel bars that each have a rear end mounted in rotation on the upper end of the lower element 2, as well as a front end on which thebasketball backboard 4 is mounted in rotation. As such, the upper element 3 forms a deformable parallelogram that allows the user to switch said upper element into deployed position and to upright thebasketball backboard 4 in a single gesture. - Furthermore, in order to facilitate the arrangement of the upper element 3 in deployed position, said upper element comprises a
handle 16 that the user can grasp in order to manipulate said upper element. - The play structure further comprises a system for locking the upper element 3 in deployed position, in order to prevent any untimely tipping over of said upper element in folded position, in particular during the use of the structure, and as such ensure the safety of the users.
- To do this, the system for locking comprises a
hook 17 mounted on one among the upper 3 and lower 2 elements, said hook being hooked manually on the other among said lower and upper elements when said upper element is in deployed position. In particular, thehook 17 can be mounted in rotation in order to facilitate the manipulation thereof by the user. - In relation with
FIG. 5b , thehook 17 is mounted on the upper element 3 and the lower element 2 comprises a device carrying apin 18 on which said hook is hooked when said upper element is in deployed position. - In the
FIGS. 3 , the lower element 2 is in upright position and the upper element 3 is in deployed position, thebasketball backboard 4 and thehoop 4 b that it carries being upright towards the front. The play structure can therefore be used. - However, according to the level of practice of the user, his age and/or his size, the height of the
backboard 4 can be adjusted. To do this, the lower element 2 comprises afirst portion 2 a mounted slidingly in asecond portion 2 b between a retracted position in said second portion (FIGS. 3 ) and a raised position outside of said second portion (FIGS. 4 ), said lower element being provided with a system for actuating the movement of said first portion in raised position. - In particular, the lower end of the
second portion 2 b is mounted in rotation on the central frame 5 and carries the twolegs 15, and the upper element 3 is mounted in rotation on an upper end of thefirst portion 2 a. - In relation with the
FIGS. 5 , the system for actuating comprises astrap 19 of which a first end is fastened to thesecond portion 2 b, said strap being mounted on a means for winding around its second end. In particular, the means for winding comprises a crank 20 mounted on thesecond portion 2 b, in particular on acase 21 carried by said second portion and inside of which the second end of thestrap 19 opens in order to be wound around said crank. - Furthermore, the
second portion 2 b comprises aslide 22 fastened on its upper end, with thestrap 19 sliding outside of said slide during its winding around its second end. - Moreover, the
first portion 2 a is bearing on thestrap 19 between its first and second ends in order to be able to be moved in raised position—respectively retracted—by winding—respectively unwinding—of said strap. - In relation with the
FIGS. 5 and 5 a, thefirst portion 2 a comprises aslide 23 formed on its lower end and wherein thestrap 19 slides during the actuating of the system. - In order to prevent the total weight of the
first portion 2 a—upper element 3—basketball backboard 4 unit from resting on thestrap 19, in particular on the portion of said strap arranged in theslide 23 of said first portion, the system for actuating can include a safety device which, when it is actuated, supports said first portion in order to block it at the desired height. - In particular, such a safety device can comprise a pin intended to be arranged in an orifice formed on the
first portion 2 a and corresponding to a desired height for thebackboard 4, with the user pulling said pin outside of said orifice before unwinding thestrap 19 of the means for winding 20 when he wishes to retract said first portion in said second portion, for example during the arranging of the structure in storage position. - In order to ensure the safety of users during the use of the play structure, the system for actuating further comprises a device for blocking the
first portion 2 a in raised position, in order to prevent any untimely movement of said first portion towards its retracted position, and therefore any abrupt and uncontrolled lowering, and therefore potentially dangerous, of thebasketball backboard 4. - To do this, the device for blocking is in particular arranged to block the means for winding 20 the
strap 19, in such a way that the user has to manually actuate said device in order to be able to unwind said strap and as such arrange thefirst portion 2 a in retracted position. - In particular, the device for blocking can be a safety device with a pin such as described hereinabove, of which the pin is arranged to block the
first portion 2 a in raised position while blocking in rotation the means for winding 20 thestrap 19. As such, in order to be able to unwind thestrap 19, the user is required to first remove the pin, which makes it possible to prevent thestrap 19 from being unwound while thefirst portion 2 a is blocked in raised position. Indeed, if the user were to unblock thefirst portion 2 a while thestrap 19 is unwound, said first portion would abruptly slide in thesecond portion 2 b, which would result in an abrupt and uncontrolled descent, and therefore potentially dangerous, of thebasketball backboard 4. - According to another embodiment, the device for blocking can include a ratchet wheel comprising teeth on its circumference and integral in rotation with the means for winding 20, as well as a latch intended to snap fit into one of the teeth of said wheel when the means for winding 20 is actuated to wind the
strap 19 and raise thefirst portion 2 a, in such a way as to form an abutment with said tooth in order to prevent the rotation of said means in the reverse direction of unwinding of said strap. As such, in order to be able to unwind thestrap 19 and retract thefirst portion 2 a, the user must first manually release the latch of the ratchet wheel. - According to another embodiment, in particular when the means for winding comprises a crank 20, the device for blocking can also comprise a means intended to interfere with said crank in order to prevent the rotation thereof in the direction of unwinding of the
strap 19. In particular, the system for actuating comprises alatch 24 mounted in rotation on thesecond portion 2 b in the vicinity of the crank 20, the user manually turns said latch in order to arrange it against the handle of the crank 20 in order to block the latter in rotation.
