Description

Handle having a gas spring

The present invention relates to the field of sleeves comprising a first tube and a second tube.

The present invention also relates to a landing net having such a handle.

STATE OF THE PRIOR ART

In the field of handles, it is known to use a handle with at least a first tube and a second tube arranged telescopically.

These handles can be used to form landing nets, brushes or even brooms, for example. For example the handle is connected to a net to form a landing net.

However, this solution has the drawback that its implementation requires both hands free. However, often, as during fishing actions, at least one hand is already taken for example by the fishing rod. It is therefore necessary to plan to have assembled the handle in advance.

Another disadvantage is that the handle takes up a significant amount of space once deployed and is therefore not easily transportable.

The present invention aims to respond to all or part of the problems presented above.

In particular, a goal is to provide a solution that meets at least one of the following objectives:

- provide a handle that can be operated with one hand;

- provide a handle which is easily transportable;

- provide a landing net that can be used with one hand.

This goal can be achieved by providing a handle comprising:

• at least one first elongated tube along a longitudinal direction and at least one second tube configured to slide in whole or in part inside the first tube along the longitudinal direction;
• an actuation system, comprising a locking and unlocking device, capable of adopting on the one hand a locking configuration in which the second tube is blocked in sliding by the locking and unlocking device, and an unlocking configuration in which the locking and unlocking device allows the sliding of the second tube;
• a first gas expansion device comprising a first end in contact with the actuation system, and a second end collaborating with an element slidably integral with the second tube.

Some preferred but non-limiting aspects of such a handle are as follows.

The first gas expansion device comprises a compression chamber containing a gas and an extension rod configured to move in whole or in part in the compression chamber of said first gas expansion device;

the extension rod can adopt:

on the one hand an extension configuration in which the gas is at a first pressure greater than atmospheric pressure and in which the extension rod extends mainly outside the compression chamber so that in all or part of the second tube is arranged outside the first tube, and on the other hand a retracted configuration in which the extension rod is arranged mainly inside the compression chamber so as to compress the gas of the chamber compression at a second pressure higher than the first pressure and so that all or part of the second tube is arranged inside the first tube;

the retracted configuration of the extension rod being obtained when the locking and unlocking device is in the locking configuration and when a force is exerted on the second tube in the longitudinal direction, so that the gas in the compression chamber of the first gas expansion device is compressed to the second pressure;

the extension configuration of the extension rod being obtained when the locking and unlocking device is in the unlocking configuration.

The handle includes a second gas trigger device and wherein the second gas trigger device includes a first end collaborating with an end of the first gas trigger device selected from the first end and the second end, and a second end collaborating with an element slidably secured to the second tube.

The second gas expansion device comprises a compression chamber containing a gas and an extension rod of the second expansion device configured to move in whole or in part in the compression chamber of said second gas expansion device;

the extension rod of the second trigger device can adopt:

on the one hand an extension configuration in which the gas is at a first pressure of the second gas expansion device greater than atmospheric pressure and in which the extension rod of the second expansion device extends mainly to the outside the compression chamber so that all or part of the second tube is arranged outside the first tube, and

on the other hand, a retracted configuration in which the extension rod of the second expansion device is arranged mainly inside the compression chamber so as to compress the gas from the compression chamber to a second pressure of the second pressure relief device gas expansion and so that all or part of the second tube is inside the first tube;

the retracted configuration of the extension rod of the second expansion device being obtained when the locking and unlocking device is in the locking configuration and when a force is exerted on the second tube, in the longitudinal direction, so that the gas from the compression chamber of at least one element selected from the first gas expansion device and the second gas expansion device is compressed to the second pressure of the second expansion device;

the extension configuration of the extension rod of the second trigger device being obtained when the locking and unlocking device is in the unlocking configuration.

At least one of the gas expansion devices selected from the first gas expansion device and the second gas expansion device is arranged in at least one tube selected from the first tube and the second tube.

The locking and unlocking device comprises a spring operable from outside the first tube,

the spring collaborating with a part integral with the second tube so that, in the locking configuration of the locking and unlocking device, the spring blocks the second tube in sliding, and that in the unlocking configuration of the locking and unlocking device, the spring allows the sliding of the second tube.

DETAILED EXPLANATION OF PARTICULAR EMBODIMENTS

In the appended FIGS. 1 to 2 and in the remainder of the description, elements which are identical or similar in functional terms are identified by the same references. In addition, the various elements are not represented to scale so as to favor the clarity of the figures to facilitate understanding. Furthermore, the different examples, embodiments and variants are not mutually exclusive and can, on the contrary, be combined with one another.

In the remainder of the description, unless otherwise indicated, the terms “substantially”, “approximately”, “overall” and “of the order of” mean “within 10%”.

The invention relates firstly to a handle 50.

The fields of use of this handle 50 can be varied and the handle 50 can be used for example in the field of landing nets, brushes or even brooms. However, the 50 handle is not limited to these applications.

The landing nets comprising the handle 50 according to the invention can be adapted for the fields of fishing, the capture of birds, mammals or crustaceans, or even for the field of the swimming pool.

As illustrated in Figures 1 and 2, the handle 50 comprises at least a first tube 1 elongated in a longitudinal direction. The handle 50 also includes at least one second tube 10 configured to slide in whole or in part inside the first tube 1 along the longitudinal direction. In other words, the diameter of the second tube 10 is smaller than that of the first tube 1. By the term “sliding” is meant “translating in one direction or the other, in the longitudinal direction, without resistance or with resistance”. The first and second tubes 1, 10 can be made of composite material, plastic, metal such as aluminum, fiberglass, or even carbon such as graphite to save weight.

The first and second tubes 1, 10 can have a cylindrical shape with the possibility of sliding parallel to each other. Extruded tubes can thus be implemented to produce the first and second tubes.

The first and second tubes 1, 10 can also have a slightly tapered shape so that the diameter of each end of the tubes is different from the diameter of the opposite end. This allows the second tube 10 not to escape completely from the first tube 1.

The handle 50 further comprises an actuation system 40, integral or not with the first tube 1.

The actuation system 40 includes a locking and unlocking device 30. As illustrated in the , the locking and unlocking device 30 is capable of adopting a locking configuration F in which the second tube 10 is blocked in sliding by the locking and unlocking device 30.

In one example, the locking and unlocking device 30 comprises a spring 31 operable from the outside of the first tube 1. For this purpose, an orifice can be arranged in the first tube 1 in order to pass a lug or a button through the wall of the first tube 1. The user, by pressing the lug or the button from outside the tube 1, transmits pressure to the spring 31 which comes into action. In an example illustrated in Figures 1 and 2, the spring 31 collaborates with an integral part 32 of the second tube 10. This integral part 32 may or may not belong to the second tube 10. The integral part of the second tube consists, in one example, of a ring 32 comprising a notch. In the locking configuration F of the locking and unlocking device 30, the spring 31 is engaged in the notch of the integral part 32 of the second tube 10. This makes it possible to block the second tube 10 in sliding. When the spring 31 is pushed back by an action on the lug or on the button, it disengages from the notch of the integral part 32 so as to release the second tube 10 by sliding. The unlocking configuration O of the locking and unlocking device 30 is then implemented.

The handle 50 further comprises at least one first gas expansion device 12 . By gas expansion device, reference is made, for example, to a gas spring, a gas cylinder, a gas piston such as, for example, a gas cylinder present on car trunks or furniture.

The first gas expansion device 12 comprises a first end in contact, that is to say in contact in a fixed or removable manner, with the actuation system 40 and in particular with the locking and unlocking device 30. It comprises also a second end collaborating with an element slidably secured to the second tube 10. This element may or may not be part of the second tube 10, and may also be an end of a second gas expansion device 22 if the latter is present . The first gas expansion device 12 can thus cause the second tube 10 to slide directly or indirectly by sliding the element integral with sliding, such as for example the second gas expansion device 22 if the latter is here.

This architecture is advantageous for obtaining a landing net handle that can be deployed by simple action with one hand. This is advantageous for example when the other hand is busy.

The minimum number of gas expansion devices is one. However two, three or more gas trigger devices can be inserted into the handle 50 along the longitudinal direction in order to increase the reach of the handle.

There may thus be provided a third tube or even a fourth or a fifth tube or more, each of which can slide in the previous one telescopically for example. The second, third and other successive tubes can move along the longitudinal direction according to the extension of the extension rod of the gas expansion device present inside. Each of the gas expansion devices thus makes it possible to increase the elongation, in other words the range of the handle 50, even more.

Several gas expansion devices 12, 22 can be arranged in the same tube in order to increase the range of the handle 50.

In an example where a second gas expansion device 22 is present in the handle 50, when the locking and unlocking device is actuated in the unlocking configuration O, the first gas expansion device 12 drives the second gas expansion valve 22 which itself slides the second tube 10 so that the latter is only partially covered by the first tube 1.

In one example, the first or each of the gas expansion devices 12, 22 comprises a compression chamber containing a gas having a first pressure greater than atmospheric pressure. The first pressure of each gas expansion device 12, 22 may be different from one gas expansion device 12, 22 to another.

The first or each of the gas expansion devices 12, 22 comprises an extension rod 12a, 22a configured to move in whole or in part in the compression chamber of said first gas expansion device 12, 22. The extension rod 12a, 22a can thus adopt a retracted configuration F1 in which the extension rod 12a, 22a is arranged mainly inside the compression chamber so as to compress the gas from the compression chamber to a second pressure higher than the first pressure and so that the second tube 10 is wholly or partly inside the first tube 1.

The second pressure of each gas expansion device 12, 22 can be different from one gas expansion device 12, 22 to another.

The extension rod 12a, 22a can also adopt an extension configuration O1 in which the gas is at the first pressure and in which the extension rod 12a, 22a extends mainly outside the compression chamber . Thus, the gas expansion device 12, 22 extends by the extension of its extension rod. The second tube 10 -respectively the third, fourth,...- is thus driven in whole or in part outside the first tube 1 -respectively outside the previous tube-.

Gas expansion devices 12, 22 should be, by default, with the extension rod deployed outside the compression chamber. In other words, without application of a longitudinal force tending to bring the extension rod 12a, 22a back into the combustion chamber, the extension rod 12a, 22a extends wholly or partly outside of the compression chamber. This is due to the first pressure higher than the atmospheric pressure which prevails, by its construction, in the compression chamber.

The retracted configuration F1 of each of the extension rods 12a, 22a is obtained when a force is applied, in the longitudinal direction, to the second tube 10 -respectively the third, the fourth,...-. Thus, the extension rods 12a, 22a of each gas expansion device 12, 22 compress in turn in their respective compression chamber. The gas is compressed to reach the second pressure of each compression chamber.

To activate the locking and unlocking device in its locking configuration F, a longitudinal force is applied to the second tube -respectively the third, fourth tube...- so as to compress the extension rods of the gas expansion devices in the presence in each compression chamber gas expansion devices present. Thus, the gas expansion devices other than the first gas expansion device 12 are driven in the direction of the first gas expansion device 12. When the integral part 32 of the second tube 10 meets the spring 31, the latter deforms to fit into the notch of the integral part 32. The locking configuration F is thus obtained and the second tube 10 is blocked in sliding.

Thus, each gas expansion device 12, 22 finds itself storing an expansion energy which will be returned in the form of an extension of their extension rod when the locking and unlocking device 30 is actuated to pass into the configuration of unlocking 0. Indeed, in this configuration, the tubes other than the first tube 1, find themselves free to slide and are slid away by the pressure exerted by the extension rods 12a, 22a which return to their extension configuration O1 which is, by default, in extension.

In an example where the handle 50 includes a second gas expansion device 22, the second gas expansion device 22 includes a first end cooperating directly or indirectly via one or more parts with the first end or the second end of the first gas expansion device 12. In this example, the second gas expansion device 22 comprises a second end collaborating in a fixed or removable manner with an element integral with the second tube 10 which may or may not be part of the second tube 10, or with one end of a third expansion device gas.

In general, the arrangement of the gas expansion devices 12, 22, inside the handle 50, can be implemented without distinction. Thus, the gas expansion devices 12, 22 can be oriented in the same direction or head to tail. In the latter case, the two extension rods of two adjacent gas expansion devices are arranged face to face.

It may however be advantageous from a weight point of view to arrange the gas expansion devices in such a way that their compression chamber is arranged in the direction of the end where the handle 50 is held in the hand.

In one example, at least one of the first gas expansion device 12 and the second gas expansion device 22 is arranged in at least one tube chosen from among the first tube 1 and the second tube 10. This allows a compact arrangement. In general, the gas expansion devices must be arranged advantageously to be able to slide in each of the tubes of the handle 50.

The invention also relates to a landing net comprising a handle 50 as described previously.

The landing net may include a net carried by a frame. The frame can cooperate in a fixed or removable manner with one end of the handle 50, for example with a screw adaptation system.

Such a landing net 80 makes it possible to be implemented or deployed with one hand and to be easily transportable.

The invention also relates to a brush comprising a handle 50 as described above.

The brush is attached to one end of the handle 50.

Such a brush makes it possible to be implemented or deployed with one hand and to be easily transportable.

The invention also relates to a broom comprising a handle 50 as described above.

The broom is attached to one end of the handle 50.

Such a broom makes it possible to be implemented or deployed with one hand and to be easily transportable.
