Description

Title of the invention: TELESCOPIC DEVICE FOR MANUALLY PICKING UP OBJECTS Technical field

[0001] The present invention relates to the field of collecting objects, and more particularly the manual collection of waste located on the ground, for example on sidewalks or in ditches. The invention relates more particularly to a telescopic gripper for collecting such waste. STATE OF THE PRIOR ART

[0002] For many years, particularly for collecting waste located on the ground, the use of collection devices such as grippers allowing a user to pick up waste without having to bend down / bend towards the ground has been known. These devices generally comprise a handle. A first end of the handle comprises a grip having actuating means and the second end has a gripper forming a movable jaw capable of moving between a closed position when the actuating means are actuated by the user and an open position when the actuating means are released by the user.

[0003] Although these devices are generally effective for waste collection, they take up relatively much space when not in use. In particular, they are not suitable for children, who can be effective actors in maintaining the cleanliness of a city. They are not always suitable for the environment in which they are used, which may be ditches, embankments or lawns. In addition, their storage requires a relatively large amount of space. Such devices are therefore not satisfactory.

[0004] An object of the invention is to provide a waste collection device which is easily adaptable to the user, and the environment in which it is used and easily transportable. Statement of the invention

[0005] An object of the present invention is to provide a device for collecting objects, and in particular waste, which is portable and easily handled as well as compact in the retracted position in order to facilitate its storage.

[0006] To this end, the invention proposes a device comprising:

[0007] - a tube comprising at least three parts, preferably six parts, telescopable between them;

[0008] - a handle intended to be held by a user and comprising an integral body from a first end of the tube;

[0009] - a clamp attached to a second end of the tube, said clamp comprising two jaws of which at least one is movable in rotation relative to the second end of the tube around an axis of rotation between a spread position and a clamped position;

[0010] - a mechanism for actuating the clamp;

[0011] - a cable for actuating the clamp; and,

[0012] - winding means for the cable, driven by the actuating means and arranged so that the passage of the actuating mechanism from a released position to an actuated position causes the cable to be wound and the jaws to pass from the spread position to the clamped position;

[0013] the actuating mechanism comprising means for returning the jaws to the separated position when the actuating mechanism moves from the actuated position to the released position.

[0014] The two jaws can be movable, and preferably each movable about a respective axis of rotation.

[0015] The winding means advantageously comprise rotational return means so that they allow the length of the cable to be adjusted when the tube is deployed or returned to the retracted position.

[0016] Furthermore, the device may be such that:

[0017] - the actuating mechanism comprises an actuating lever mounted movably in rotation relative to the body, between the released position, and the actuated position and at least a first rack;

[0018] - the winding means comprise a first movably mounted toothed wheel rotating around an axis of rotation mounted fixed relative to the body, the first rack of the actuating lever not cooperating with said first toothed wheel in said released position of the actuating lever;

[0019] - the actuating cable comprising a first end fixed to the first toothed wheel and a second end secured to each movable jaw, the cable being designed to be wound around the first toothed wheel when the first toothed wheel rotates in a first direction of rotation and to be unwound from the first toothed wheel when said first toothed wheel rotates in a second direction of rotation;

[0020] and in which the passage of the actuating lever from the released position to the actuated position causes the rotation of the first toothed wheel in the first direction of rotation, the winding of the cable and the passage of the jaws from the spread position to the clamped position.

[0021] Furthermore, the device may be such that:

[0022] - the parts of the tube extend coaxially along a longitudinal axis of the device, and are movable in translation relative to each other along the longitudinal axis to take a retracted position or an unfolded position;

[0023] - the rotary return means comprise a spiral spring;

[0024] - the first toothed wheel comprises a first central bore for the passage of its axis of rotation, a first cylinder carrying teeth cooperating with the first rack, and a second cylinder;

[0025] - this second cylinder comprises on its outer periphery, a gutter winding for the cable, and, inside it, a housing in which the spiral spring is housed;

[0026] - this spiral spring comprises a central part fixed to the rotation axis of the first wheel and an outer part fixed to an inner surface of the second cylinder delimiting the housing, the spiral spring exerting a return force in the first direction of rotation on the first toothed wheel relative to the rotation axis of the first wheel, so that by controlling the rotation of the first toothed wheel it allows the length of the cable to be adjusted when the tube is deployed or returned to the retracted position.

[0027] The lever may comprise a second rack extending substantially parallel to the first rack, and the mechanism may comprise a second toothed wheel mounted to rotate about the rotation axis of the first wheel, the second rack not cooperating with the second toothed wheel in the released position of the lever.

[0028] The second toothed wheel advantageously comprises a second central bore extending coaxially with the first central bore for the passage of the rotation axis of the first wheel, a first cylinder carrying teeth cooperating with the second rack, and a second cylinder in the form of a wall intended to close the housing of said first toothed wheel.

[0029] The clamp advantageously comprises a support carrying the axes of rotation of the jaws, the means for returning the jaws to the spaced position comprising an axial spring arranged between the jaws and a stop provided in the support such that when the actuating mechanism moves from the actuated position to the released position, the axial spring exerts a force between the jaws and the stop causing the jaws to move from the clamped position to the spaced position.

[0030] Preferably, a device according to the invention has a total length, measured along the longitudinal axis, of less than twenty-five centimeters in the retracted position. Brief description of the drawings

[0041] DETAILED DESCRIPTION OF AN EXAMPLE OF EMBODIMENT

[0042] Figures 1 to 9 show a device 1 according to the invention for collecting objects, and more particularly waste. The device 1 comprises a tube 2. The tube 2 is telescopic and comprises at least two parts 21a - 21f extending coaxially along a longitudinal axis X of the device 1. The parts 21a - 21f are movable in translation relative to each other along the longitudinal axis X.

[0043] In this example, the tube 2 comprises six parts 21a, 21b, 21c, 21d, 21e and 21f. In order to provide an optimized footprint, the parts 21a - 21f are inserted into each other. In other words, the part 21f having the largest diameter is located furthest to the outside while the part 21a having the smallest diameter is located furthest to the inside of the telescopic tube 2. In a variant, the reverse is also possible.

[0044] The telescopic tube 2 can take a retracted position as illustrated in Figures 6 to 9 and a deployed position, as illustrated in Figures 1 and 2. Figures 1 and 2 illustrate the device 1 in the deployed position, and more precisely a maximum deployed position. In the retracted position, the parts 21a - 21f are inserted into each other to ensure minimal bulk. From the retracted position, it is possible to move the parts 21a - 21f in translation relative to each other so as to provide a deployed position for the tube 2. It is understood that the deployed position is a position of the tube 2 located between the retracted position (Figures 6 to 9) and the maximum deployed position (Figures 1 and 2). It is conceivable to provide that the tube 2 can be used in any deployed position between the retracted position and the maximum deployed position, or at predetermined positions, for example located at each junction between the parts 21a - 21f of the tube 2.

[0045] A first end 22a of the tube 2, located at the level of the part 2If of the tube 2 having the largest diameter, carries a handle 3, having a substantially cylindrical shape and extending coaxially to the longitudinal axis X of the device 1. A second end 22b, axially opposite the first, carries a clamp 4.

[0046] The handle 3 comprises a body 30 comprising a central tubular cavity 31 which extends rectilinearly and coaxially to the longitudinal axis X. The central cavity 31 is intended to receive the tube 2 in the retracted position so as to limit the size of the device 1 substantially to the dimensions of the handle 3 and the clamp 4 described below. In this example, the cavity 31 of the body 30 receives substantially the entire part 21f of the tube 2.

[0047] Preferably, the body 30 of the handle 3 has an ergonomic shape making it easier for the user to hold the device 1.

[0048] The second end 22b of the tube 2, located at the portion 21a of the tube 2 having the smallest diameter, carries the clamp 4, this clamp making it possible to grip the objects. The clamp 4 comprises at least two jaws movable in rotation relative to the tube 2, each around an axis of rotation. In this example, the clamp 4 comprises a first 41a and a second 41b jaws movable in rotation respectively around a first axis 412a and a second axis 412b of rotation. The first 412a and second 412b axes of rotation here extend generally parallel to each other and also extend generally perpendicular to the longitudinal axis X of the device 1.

[0049] In this example, a support 42 is integral with the second end 22b of the tube 2 and carries the first 412a and second 412b axes of rotation of the jaws 41a, 41b. Optionally, the support 42 can be mounted to be able to rotate relative to the second end 22b of the telescopic tube 2 to orient the clamp 4.

[0050] The ends 410a, 410b of the jaws 41a, 41b located at the level of the support 42 are mounted articulated around the same actuation axis 411. The actuation axis 411 is here arranged in the support 42 and is connected to an actuation cable 54 described in more detail in the remainder of this description.

[0051] The jaws 41a and 41b of the clamp 4 are movable between a spaced position (illustrated in Figures 1, 6 and 7), also called the open position, and a clamped position (illustrated in Figures 2, 8 and 9) corresponding to a closed or partially closed position of the clamp 4.

[0052] In the separated position, the jaws 41a and 41b are spaced from each other by a first distance dmax corresponding to the maximum opening of the clamp 4. The The spaced position makes it easier to approach and position the clamp 4 above the object(s) so as to facilitate their collection.

[0053] Once the clamp 4 is correctly positioned relative to the object, the jaws 41a and 41b can be moved, via the actuating mechanism 5 described below, from the spaced apart position to the clamped position which allows the object to be gripped.

[0054] The clamped position corresponds to a spacing of the jaws 41a, 41b less than that of the spread position. Thus, the clamp 4 can provide a clamped position in which the jaws 41a, 41b are spaced apart by a second distance less than the distance dmax of the spread position. The clamped position is therefore variable depending on the spacing of the jaws 41a and 41b, which makes it possible in particular to grip objects of varying dimensions.

[0055] In order to ensure optimal gripping of the objects, the jaws 41a and 41b each comprise a plurality of teeth 413 extending on the faces of the jaws 41a and 41b facing each other.

[0056] The device 1 comprises a mechanism 5 for actuating the clamp 4 making it possible to move the jaws 41a, 41b of the clamp 4 between the spread position and the clamped position. The actuating mechanism 5 firstly comprises an actuating lever 51, also called a trigger, which can be actuated by the user and which is integral with the handle 3. The actuating lever 51 is mounted to be able to rotate relative to the body 30 of the handle 3 about a third axis of rotation 511. More precisely, the lever 51 comprises a body 510, a first end 510a of which is integral with the third axis of rotation 511, which is here arranged substantially at the end 30a of the body 30 located on the side of the tube 2.The third axis of rotation 511 of the lever 51 extends substantially perpendicular to the longitudinal axis X of the device 1 and has a spring 515 making it possible to automatically return the lever from the actuated position to the released position described below when the user releases the latter.

[0057] The actuating lever 51 is movable between a released position, illustrated in figures 1, 6 and 7, which here corresponds to the spaced position of the clamp 4 and an actuated position, illustrated in figures 2, 8 and 9, which here corresponds to the clamped position of the clamp 4.

[0058] In the released position of the actuating lever 51, the third distance d'max between the second end 510b of the actuating lever 51, that is to say the end opposite the first end 510a cooperating with the third axis of rotation 511 of the actuating lever 51, and the free end 30b of the body 30 is maximum. When the actuating lever 51 is actuated, causing the latter to pass from the released position to the actuated position, the fourth distance between the second end 510a of the actuating lever 51 and the free end 30b of the body 30 decreases and is therefore less than the third max distance.

[0059] As particularly illustrated in [Fig.4], the actuating lever 51 comprises, at a second end 510b, an upright 512 extending substantially perpendicularly to the body 510 of the lever 51 in the direction of the body 30 of the handle 3. The upright 512 carries a first rack 513 and a second rack 514 which extend substantially parallel and which have teeth generally oriented towards the third axis of rotation 511 of the lever 51.

[0060] The mechanism 5 further comprises a first 52 and a second 53 toothed wheel. The first toothed wheel 52 comprises a first central bore 521 and the second toothed wheel 53 comprises a second central bore 531, extending coaxially with the first central bore 521. The toothed wheels 52 and 53 are mounted fixedly relative to each other and pivot together about a fourth axis of rotation 520 mounted fixedly relative to the body 30 of the handle 3. Thus, the first 52 and second 53 toothed wheels pivot jointly, that is to say in a synchronized manner. The fourth rotation axis 520 is threaded into the central bores 521 and 531 and is arranged in the body 30. More particularly, the fourth rotation axis 520 is mounted fixed relative to a housing 301 (visible in FIGS. 3 to 5) provided in the body 30 in which the first 52 and second 53 toothed wheels and the fourth rotation axis 520 are received.The fourth axis of rotation 520 extends substantially perpendicular to the longitudinal axis X of the device 1.

[0061] The first toothed wheel 52 cooperates with the first rack 513 while the second toothed wheel 53 cooperates with the second rack 514. Thus, when the actuating lever 51 is moved between the released position and the actuated position, and vice versa, the racks 513 and 514 drive the toothed wheels 52 and 53 in rotation about the fourth axis of rotation 520. After assembling the first 52 and second 53 toothed wheels, it can be considered that they form only one toothed wheel having teeth 523a and 533a on each side of the wheel. In a variant, the first 52 and second 53 toothed wheels are in one piece.

[0062] More specifically, and as illustrated in Figures 4 and 5, the first toothed wheel 52 comprises a first cylinder 523 carrying the teeth 523a. The first toothed wheel 52 comprises a second cylinder 525, juxtaposed with the first cylinder 523. The second cylinder 525 comprises, on its outer surface, or periphery, a groove or gutter 525a in which an actuating cable 54 described in more detail below is wound. The second cylinder 525 also comprises, inside the second cylinder 525, a housing 525b in which a spiral spring 55 described below is housed. The housing 525b extends here substantially coaxially with the fourth axis of rotation 520.

[0063] The second toothed wheel 53 has a first cylinder 533 carrying the teeth 533a to which is juxtaposed a second cylinder 535 in the form of a wall 535 intended to close the housing 525b of the first toothed wheel 52 when the toothed wheels 52 and 53 are assembled on the fourth axis of rotation 520.

[0064] When the actuating lever 51 is in the released position, the first 513 and second 514 racks do not cooperate with the first 52 and second 53 toothed wheels. More precisely, the first 513 and second 514 racks do not cooperate with the first 52 and second 53 toothed wheels when the actuating lever 51 is in the released position. Indeed, an intermediate position of the actuating lever 51 is implemented during the engagement of the teeth of the racks 513 and 514 with the teeth of the toothed wheels 52 and 53. Thus, between the released position and the intermediate position of the actuating lever 51, the teeth of the racks 513 and 514 and the teeth of the toothed wheels 52 and 53 do not cooperate. Between the intermediate position and the actuated position of the actuating lever 51, the teeth of the racks 513 and 514 and the teeth of the toothed wheels 52 and 53 cooperate.

[0065] The mechanism 5 further comprises a spiral spring 55, a central portion 551 of which is fixedly mounted on the fourth axis of rotation 520 and an outer portion 552 of which is fixedly mounted on an inner surface of the second cylinder 525 delimiting the housing 525b in which the spiral spring 55 is housed. Thus, the spiral spring 55 makes it possible to exert a rotational force in a first direction of rotation on the first toothed wheel 52 relative to the fourth axis of rotation 520. This rotational force exerted by the spiral spring 55 makes it possible to control the rotation of the first toothed wheel 52 around the fourth axis of rotation 520 to adjust the length of the actuating cable 54 which is unwound when the tube 2 passes from the deployed position to the retracted position, and wound up when the tube passes from the retracted position to the deployed position.

[0066] The actuating cable 54 is therefore wound and unwound around the second cylinder 525 of the first toothed wheel 52. In order to guarantee optimal winding and unwinding, the actuating cable 54 is received in the gutter 525b. A first end of the actuating cable 54 is secured to the first toothed wheel 52 while the second end is secured to the jaws 41a and 41b so as to move the jaws 41a and 41b between the clamped position and the spread position.

[0067] The device 1 comprises means for returning the jaws 41a and 41b to the spaced position comprising an axial spring 56 disposed between the jaws 41a and 41b and a stop 421, here formed in the support 42, to exert a return force on the jaws 41a and 41b.

[0068] The operation of the device 1 is described below in relation to Figures 1 to 9. [Fig. 6] illustrates the device 1 in the retracted position and in the spread position. In these positions, the actuating lever 51 is in the released position and the clamp 4 is open, that is to say that the jaws 41a, 41b are spread apart. The axial spring 56 and the spiral spring 55 are relaxed and the actuating cable 54 is generally wound on the first toothed wheel 52.

[0069] When the user actuates the actuating lever 51 to move the actuating lever 51 from the released position to the actuated position, the movement of the actuating lever 51 will cause, via the racks 513 and 514, a rotation of the first 52 and second 53 toothed wheels in a first direction of rotation. The rotation of the first 52 and second 53 toothed wheels in this first direction of rotation will cause the actuating cable 54 to be wound around the second cylinder 525 of the first toothed wheel 52. The winding of the actuating cable 54 will cause compression of the axial spring 56 which will cause the jaws 41a and 41b to move from the spread position to the clamped position for gripping an object, as illustrated in [Fig. 8].

[0070] By releasing the actuating lever 51, the latter will move from the actuated position ([Fig.8]) to the released position ([Fig.6]), causing the axial spring 56 to decompress to its relaxed position. The movement of the axial spring 56 from the compressed position to the relaxed position will allow the first 52 and second 53 toothed wheels to rotate in a second direction of rotation, opposite to the first direction of rotation, and the actuating cable 54 to unwind. Thus, the clamp 4 will open, that is to say the jaws 41a and 41b will move from the clamped position to the spread position, allowing the picked-up object to be released (as illustrated in [Fig.6]). During all this time, the spiral spring 55 keeps the actuating cable 54 under tension to optimize the winding and unwinding of the latter.

[0071] To move the device 1 from the retracted position (figures 6 and 8) to the deployed position (figures 1 and 2), it is sufficient to manually pull on the clamp 4. In this way, the parts 21a-21f of the telescopic tube 2 move in translation relative to each other. When deploying the device 1, the actuating cable 54 is unwound and the spiral spring 55 is wound, i.e. compressed, within the housing 525b around the fourth axis of rotation 520. The axial spring 56 is configured to provide a force greater than the rotation force exerted by the spiral spring 55. Thus, when the device 1 is in the deployed position and the actuating lever 51 is not actuated by the user ([Fig.l]), the axial spring 56 makes it possible to maintain the clamp in the spread position, i.e. in the open position.

[0072] In the deployed position, the operation of the device 1 is substantially identical. Thus, when the actuating lever 51 is actuated by the user and therefore moved between the released position and the actuated position, the toothed wheels 52 and 53 pivot in the first direction of rotation, the actuating cable 54 is wound around the second cylinder 525 of the first toothed wheel 52, the axial spring 56 is compressed and the clamp 4 closes, i.e. the jaws 41a and 41b clamp. The release of the actuating lever 51 causes, as previously, the decompression of the axial spring 56, the rotation of the toothed wheels 52 and 53 in the second direction of rotation and an unwinding of the actuating cable 54 allowing the opening of the clamp 4, i.e. the separation of the jaws 41a and 41b.

[0073] The difference in length of the actuating cable 54 between the retracted position and the deployed position of the tube 2 is compensated by the spiral spring 55, which makes it possible to provide, or distribute, more or less length of actuating cable 54. The spiral spring 55 is constantly under tension and therefore always exerts a rotational force, in the first direction of rotation, on the first toothed wheel 52, so that the actuating cable 54 is also always under tension in order to ensure optimal operation of the clamp 4.

[0074] When the device 1 moves from the deployed position to the retracted position, the spiral spring 55 will unwind within the housing 525b and therefore relax so that the first toothed wheel 52 rotates in the first direction of rotation and winds up the excess length of the actuating cable 54, while the axial spring 56 will keep the clamp 4 open, i.e. with the jaws 41a and 41b apart.

[0075] It should be noted that it is not necessary, in order to grasp and then release an object and grasp an object again, to return to the spread position. Indeed, it is possible to release an object without having to move the gripper 4 to the spread position depending on the dimensions of the grasped object. Thus, it is possible to navigate between different clamped positions of the gripper 4 to successively grasp and release objects. This makes it easier to use the device 1 and increases the productivity of the user because he can thus improve his rate of objects picked up.

[0076] The invention therefore proposes a device for manually picking up objects, and in particular waste, the actuating mechanism 5 of which makes it possible to provide a relatively compact device in the retracted position. Indeed, in the retracted position, the device 1 has a total length (taking into account the handle 30, the tube 2 and the clamp 4) of less than 25 cm, and preferably a length of approximately 21 cm. In the maximum deployed position, the device 1 has a total length of greater than 50 cm, and preferably a length of approximately 67 cm. The structure of the device 1 and the actuating mechanism 5 make it possible to provide an easily portable device whose storage and handling are improved compared to the solutions of the prior art.

[0077] Of course, the invention is not limited to the examples which have just been described. On the contrary, the invention is defined by the claims which follow.

[0078] It will indeed appear to a person skilled in the art that various modifications can be made to the embodiments described above, in light of the teaching which has just been disclosed to him.

[0079] Thus, it is possible to use a single axis to articulate the two jaws. It is also possible to have one jaw fixed and the other jaw articulated.
