This application claims the priority of French patent application number 2102296, filed on Mar. 9, 2021, the entire contents of which are incorporated herein by reference.
The invention relates to a piece of equipment for playing basketball, comprising a base intended to be disposed bearing on the ground, as well as a post which has an upper section carrying a board on which a basketball hoop is mounted.
Such equipment that could be folded in order to facilitate the set-up and the storage thereof are known, in particular while limiting the need for tools and/or the time required for such operations, which actually might turn out to be dissuasive for use of said equipment as well as for storage thereof.
The documents FR-3 022 795 and FR-3 022 796 describe an equipment for playing basketball, wherein the base is equipped with two rows of wheels forming a housing therebetween, and whose post has a lower section which is rotatably mounted on said base so as to be able to dispose said post reversibly between a stowed storage configuration, wherein at least the lower section is disposed in the housing, and an upright use configuration.
To be able to improve the compactness of the equipment in the storage configuration, the upper section of the post is mounted movable relative to the lower section between a retracted position and a deployed position, in order to be able to be disposed in the retracted position when the equipment is placed in the storage configuration.
To this end, the documents FR-3 022 795 and FR-3 022 796 provide for slidably mounting the upper section on the lower section, the equipment comprising a system for actuating said movement over a stroke comprised between a retracted storage position and at least one projecting position corresponding to a height of use, said actuation system comprising a case fastened on a rear wall of the lower section and a mechanism for moving the upper section which is housed in said case, said mechanism comprising a handling socket which projects from said case.
In these documents, the movement mechanism comprises a strap whose a first end is fastened to the lower section, and whose second end could be wound around a shaft rotatably mounted in the case according to a frontal axis, said axis projecting from a lateral wall of said case to form a handling socket, to which a crank handle is associated.
For reasons related to compactness, the distance between the rows of wheels is not enough for the housing to receive the lateral socket, which leaves the possibility of an actuation of the deployment of the upper section in the storage configuration.
The invention aims to improve the prior art by providing equipment for playing basketball wherein the post could be folded on the base in a storage configuration while preventing handling of the deployment of said post, and that being so without any particular constraint on the dimension of the base.
To this end, the invention provides equipment for playing basketball, comprising a base intended to be disposed bearing on the ground, said base being equipped with two lateral structures forming a housing therebetween, said equipment comprising a post having an upper section carrying a board on which a basketball hoop is mounted, said post having a lower section which is rotatably mounted on said base so as to be able to dispose said post reversibly between a stowed storage configuration in which at least the lower section is disposed in the housing and an upright use configuration, said upper section being slidably mounted on said lower section and said equipment comprising a system for actuating said movement over a stroke comprised between a storage retracted position and at least one projecting position corresponding to a height of use, said actuation system comprising a case fastened on a rear wall of the lower section and a mechanism for moving the upper section which is housed in said case, said mechanism comprising a handling socket which projects from the case, said equipment being characterised in that said socket is disposed on a rear wall of the case and in that the housing is arranged so as to receive the lower section in the stowed configuration while preventing access to said socket.
Other particularities and advantages of the invention will appear in the following description, made with reference to the appended figures, wherein:
Referring to these figures, an equipment for playing basketball is described hereinbelow.
The equipment comprises a base 1 intended to be disposed bearing on the ground, as well as a post 2 having an upper section 2a carrying a board 3 on which a basketball hoop 4 is mounted.
The post 2 has a lower section 2b which is rotatably mounted on the base 1 to be able dispose said post reversibly between a stowed storage configuration and an upright use configuration.
The base 1 is equipped with two lateral structures 5 which form a housing 6 therebetween such that, in the storage configuration, at least the lower section 2b of the post 2 is disposed in said housing. In the represented embodiments, the base 1 comprises a frame 7 on which the lower section 2b is rotatably mounted, the lateral structures 5 being carried by said frame forming a U-like shaped housing 6 therebetween.
The two lateral structures 5 form a counterweight to the post 2 in the upright configuration for use of the equipment, in order to avoid a tilting of said equipment, and thus guarantee the safety of its users.
At least one lateral structure 5 may be arranged so as to be able to be filled with a ballast matter, for example water or sand. In the represented second and third embodiments (respectively in
For a proper distribution of the weight, in each of the represented embodiments, the lateral structures 5 have identical modules 5a which are symmetrically distributed with respect to the modules 5a of the other lateral structure 5, on either side of a sagittal midplane containing the post 2.
The base 1 is further equipped with wheels 10 to enable the movement of the equipment, in particular in its storage configuration.
In the represented first two embodiments (
In particular, in the first embodiment (
Thus, to be able to move the equipment, the user should raise the base 1 slightly on the front side, in particular by manually grasping a front transverse bar 7b forming the base of the U of the frame 7, in order to make the rear wheels 10 bear on the ground.
In the second embodiment (
In the represented third embodiment (
In particular, each of the wheels 10 forms a ballast module 5a for the corresponding lateral structure 5, and has, to this end, a cylindrical tank 8 on the periphery of which an opening 9 is disposed to enable filling thereof with a ballast matter, the axis of revolution of said tank extending horizontally and perpendicularly to the sagittal plane of the frame 7, in order to be able to move the base 1 by making said tanks roll on their periphery.
In
As regards mounting of the lower section 2b, the cradle 7a, 7b, 7d or the central beam 7c of the frame 7 has a front portion on which said lower section is rotatably mounted. Thus, to dispose the equipment in the use configuration, the user first moves the lower section 2b from the stowed configuration to the upright configuration by making it pivot relative to the front portion of the frame 7.
To facilitate its arrangement in the use configuration, the equipment comprises a connecting arm 13 which has a front end 13a hinged on the lower section 2b, as well as a rear end hinged on the base 1, in particular by being disposed in the housing 6 for receiving said lower section.
In the represented first embodiment (
In particular, the central hinge 15 comprises a pin 16 for locking the arm 13 in the deployed configuration to avoid an inadvertent folding thereof, and thus limiting the risks of tilting of the lower section 2b during the use of the equipment. The pin 13 can be manually actuated to enable a movement thereof from the locking position towards an unlocked position, in order to free the relative rotation of the segments 14 and enable the tilting of the arm 13 in the folded configuration.
In the other two represented embodiments, at least one amongst the front 13a and rear ends of the connecting arm 13 is slidably mounted respectively on the lower section 2b and the base 1.
In the second embodiment (
In particular, the carriage 19 comprises a locking pin 20 which is arranged so as to be reversibly disposed in an upper and/or lower orifice 21 formed on the rail 17, in order to block said carriage in the top and/or bottom position, and thus lock the lower section 2b in the stowed and/or upright configuration.
In the third embodiment (
The lower section 2b is further equipped with at least one foot 18 which is disposed laterally, in order to stabilise the post 2 in the upright configuration, in particular to prevent tilting thereof on the sides, in combination with the base 1 which forms a counterweight to avoid tilting thereof forwards or rearwards.
In the figures, the lower section 2b comprises two feet 18 disposed on either side of its lower end. In
The upper section 2a is slidably mounted on the lower section 2b, the equipment comprising a system 22 for actuating this movement over a stroke comprised between a retracted storage position and at least one projecting position corresponding to a height of use.
Referring to
In particular, the handling socket 24 is disposed on a rear wall 23a of the case 23, and the housing 6 of the base 1 is arranged so as to receive the lower section 2b in the stowed configuration while preventing access to said handling socket, as represented in
Thus, the risk of an inadvertent deployment of the upper section 2a when the equipment is in the storage configuration is optimally limited, and that being so without having to make considerable changes in the geometry of the housing 6, and therefore of the base 1.
In the represented embodiments, the upper section 2a is slidably mounted in the lower section 2b. In particular, as represented in
The gear wheel 26 is rotatably mounted in the case 23 according to a frontal axis A1, and the screw 27 is rotatably mounted in the case 23 according to a sagittal axis A2. The screw 27 has a rear end 27a which projects from the rear wall 23a of the case 23 and on which a metallic loop 24 is fastened forming a handling socket for manipulating the mechanism.
Advantageously, a crank handle 28 may be reversibly associated on the handling loop 24 of the screw 27, so as to be removed from said loop when the mechanism is not actuated. This arrangement allows not only limiting the bulk of the system 22 when it is arranged in the housing 6, but also limiting the risk of inadvertent actuation of the mechanism when the equipment is in the use configuration, in order to guarantee the safety of the users.
The actuation mechanism comprises two gear wheels 26, 29 with a different diameter which are secured in rotation. Referring to the sectional
The worm screw 27 may be arranged so as to require a handling of the socket 24 to actuate the upper section 2a in either one of its directions of movement. Thus, in particular, a rotation of the wheels 26, 29 in the direction of retraction of the upper section 2a when the screw 27 is not actuated is prevented, which allows ensuring holding of said upper section at the selected height, in order to guarantee the safety of the users by preventing an inadvertent retraction in the lower section 2b during the use of the equipment.
To limit the bulk of the equipment in the storage configuration, the upper section 2a of the post 2 comprises an upper segment 30a carrying the board 3 and a lower segment 30b slidably mounted on the lower section 2b, said upper segment being movably mounted relative to said lower segment between a use configuration, in which said upper segment is deployed relative to said lower segment, and a storage configuration, in which said upper segment forms a compact arrangement with said lower segment.
Thus, once the lower section 2b is in the upright position, the user can dispose the equipment in the use configuration by successively deploying the lower segment 30b out of said lower section, by actuation of the system 22 by means of the crank handle 28, and then the upper segment 30a relative to said lower segment.
In the first two represented embodiments (
In particular, this actuation system 22′ comprises a case 23′ fastened on a rear wall of the lower segment 30b and a mechanism for moving the upper segment 30a which is housed in said case, said mechanism comprising a handling socket 24′ which projects from said case.
Advantageously, the handling socket 24′ of this system 22′ is also disposed on a rear wall of the case 23′, and the housing 6 is arranged so as to receive the lower segment 30b in the stowed configuration while preventing access to said socket, as represented in
According to a preferred embodiment of the invention, the respective actuation systems 22, 22′ of the lower segment 30b and of the upper segment 30a are similar, which allows facilitating the manufacture of the equipment. In particular, the equipment may comprise a unique crank handle 28 that could be selectively and reversibly fastened on the handling socket 24, 24′ of either one of these systems during the deployment of said equipment in the use configuration.
In the represented third embodiment (
In particular, the upper segment 30a comprises at least one pair of parallel bars 31 each having a rear end rotatably mounted on the upper end of the lower segment 30b, as well as a front end on which the board 3 is rotatably mounted according to a frontal axis. Thus, the upper segment 30a forms a deformable four-bar linkage which enables the user to angularly deploy said upper segment and lay out the board 3 in one single gesture.
The equipment may further comprise a system 32 for locking the upper segment 30a in the upright configuration, in order to avoid any inadvertent tilting of said upper segment in the folded configuration, in particular during the use of said equipment, and thus ensure the safety of the users.
In
Advantageously, the board 3 is movable relative to the upper segment 30a between a use position and a storage position, which allows limiting the bulk of the equipment in the storage configuration.
In the represented three embodiments, the board 3 has a quadrilateral, in particular rectangular, geometry, which, when in the storage position, is turned by 90° with respect to its use position on the upper segment 30a. In particular, the board 3 has longitudinal and lateral dimensions which substantially correspond respectively to the sagittal and frontal dimensions of the base 1. Thus, to the extent that the base 1 has a sagittal dimension that is larger than its frontal dimension to be able to ensure the stability of the equipment with regards to a front-rear tilting, it is possible to store a rectangular board that is satisfactory for the sports practice, within the bulk of said base.
In the represented first two embodiments, the board 3 is reversibly mounted on the upper segment 30a between a mounted use position and a dismounted storage position, the post 2 in the storage configuration enabling the storage of the dismounted board 3 on the base.
For this purpose, with reference to
In
The connector 35 is equipped with a locking pin 36 which could be actuated between a stable blocking position, in which said pin is fitted into an orifice provided to this end in the upper segment 30a, and a constrained mounting position, in which said pin is retracted from the orifice.
In
In particular, the connector 35 comprises a vertical leg 61 which extends in the recess 60, said leg being arranged so as to be disposed in the complementary vertical housing 62 provided to this end in the upper end of the upper segment 30a.
The upper segment 30a is equipped with a locking pin 36′ which could be actuated between a stable blocking position, in which said pin crosses the housing 62 of the upper segment 30a to fit onto a locking stop provided to this end on the leg 61 of the connector 35, and a constrained mounting position, in which said pin is retracted from said housing.
In these two embodiments, the locking pin 36, 36′ comprises an internal end intended to be fitted into the orifice of the segment 30a or on the stop of the leg 61, as well as an external end on which is mounted a grip 37, 37′ to enable the user to move said pin towards its constrained mounting position by pulling on said grip.
Moreover, the pin 36, 36′ is equipped with an elastic biasing means, for example in the form of a spring, which is arranged so as to be elastically loaded upon a pull on the grip 37, 37′ in order to elastically urge said pin towards its stable position when the user releases said grip.
In the first embodiment (
Advantageously, each lateral structure 5 has such a housing 38, which enables the user to dispose the dismounted board 3 on the base 1 by indifferently disposing the connector 35 on one of said lateral structures.
In the represented third embodiment (
Referring to
The extension 41 of the subplate 40 comprises a U-like shaped structure whose two branches 42 carry means for joining together the upper end of the upper section, the base 42a of said U-like shape being engaged into the pivot connection.
In particular, each branch 42 has a pair of vertical lateral plates 43 between which the upper end of respectively one bar 31 is rotatably mounted.
The extension 41 is clamped against the board 3 with at least one friction insert 45 interposed therebetween, the equipment further comprising a clamping adjustment means 46 in order to optimise the friction torque of the rotation.
For this purpose, the rotational mechanism 39 comprises a rear cup 47 fastened on the rear face of the board 3 and a front cup 48, the extension 41 being disposed between the cups 47, 48 which are equipped with means 46 for clamping said extension therebetween, at least one cup 47, 48 housing a friction insert 45.
In
Each insert 45 is immobilised in rotation between the cups 47, 48, and comprises a friction bushing 45a which is clamped respectively on a rear 41b and a front 41a face of the extension 41 through a clamping bushing 47a, 48a formed on the adjacent cup 47, 48.
The extension 41 has a square section, as represented in particular in
Each clamping bushing 47a, 48a has indentations 49, and in particular two indentations 49 with identical angular dimensions which are diametrically opposite along said bushing.
After having disposed the lower section 2b in the upright configuration, the user can dispose the board 3 in the use position by making it pivot by means of the rotational mechanism 39. Afterwards, the user can make the upper segment 30a pivot to dispose it in the upright configuration, and then erect the lower segment 30b out of the lower section 2b by actuation of its system 22, up to the desired height of the board 3.
The use position of the board 3 is delimited by the abutment of the subplate 40 on a member 50 secured to said board. Advantageously, the stop member 50 of the board 3 comprises a means 51 for locking the use position, which allows safeguarding said position, in particular by avoiding any inadvertent rotation of said board during the use of the equipment.
