Definitions
- the invention relates to a baggage-type leather article, comprising at least two half-shells secured to each other at least partially by a closing mechanism, as well as a deployable and retractable handle mechanism and which is at the same time. less partially housed in one of the half-shells.
- This could be, for example, a suitcase, or a trunk, or any other similar item.
- Luggage comprising two half-shells and a closing mechanism, for example formed of a zipper, configured to connect the two half-shells in a closed configuration of the luggage; as well as a deployable and retractable handle mechanism which is at least partially housed in one of the half-shells.
- a closing mechanism for example formed of a zipper, configured to connect the two half-shells in a closed configuration of the luggage; as well as a deployable and retractable handle mechanism which is at least partially housed in one of the half-shells.
- the mechanism is configured so that when the handle is actuated in rotation, the internal profiles are driven in rotation with respect to the external profiles which generates a locking by friction and therefore a maintenance in position of the handle.
- the friction phenomenon can be obtained by varying the section of the internal profiles or by means of a deformable collar. Disclosure of the invention
- the invention aims to provide a luggage-type leather article of a similar kind having an improved deployable and retractable handle mechanism making its use particularly safe, while remaining simple and convenient.
- the subject of the invention is thus a baggage-type leather article, comprising at least two half-shells as well as a deployable and retractable handle mechanism which is at least partially housed in one of the half-shells and which is configured to lock. / unlock a handle of the article in a position selected from among a plurality of deployment positions of the handle relative to the half-shells, by rotating a gripping portion of the handle; characterized in that the deployable and retractable handle mechanism comprises a handle shaft to which is subject the gripping portion movable in rotation, at least one sleeve mounted fixedly in one of the half-shells, at least one profile mounted movable in translation with respect to to the sleeve, and at least one locking / unlocking system secured to said at least one section, housed at least partially in said at least one sleeve and configured to be actuated by the handle shaft, with said at least one locking system / unlocking which comprises at least one seal and which, in a first position of the gripping portion and of the handle
- the rotation of the gripping portion of the handle from one to the other of the first and second positions of the handle and of the handle shaft allows the locking / unlocking of the translation. of the handle relative to the half-shells, in order to deploy / retract the handle. In other words, it is possible to adjust the height of the luggage handle.
- the locking of the handle in a selected position is here obtained by expansion of the seal and therefore by friction between the seal and the internal face of the sleeve, thus generating mechanical resistance between the surfaces which are in close contact.
- the mechanical resistance generated is sufficient to prevent the translation of the profile in the sleeve when the user of the luggage drives the latter in motion, whether for example when carrying it or when rolling it if the luggage is equipped with casters.
- the use of the phenomenon of friction by joint is interesting because it offers improved ergonomics in the use of luggage.
- the seal locking / unlocking system is silent because the compression and decompression of the seal is done quietly.
- the locking / unlocking system with seal makes it possible to improve the guiding of the profile in the sleeve because even in its decompressed state where the seal allows the translation of the profile relative to the sleeve, the seal can be found substantially in contact with the inner face of the sheath.
- Such a loose contact does not generate a mechanical resistance between the surfaces like that mentioned above, but it can make it possible to take up a clearance between the profile and the sleeve.

- the tubes 48 are not stressed and the elastic members 62 keep the clamps 50 as close as possible to the sleeves 49 so that the seals 51 are compressed.
- the compressed seals 51 are found here in the part of the sleeves which has an enlarged internal section.
- Figures 21 to 23 show the actuation of the ejection button 22, located adjacent to the gripping portion 21, with a view to controlling the locking system 93 and thus ejecting the profiles 46 and therefore the handle 18 d 'a predetermined height.
- Pressing the ejection button 22 makes it possible to act on the actuating tab 98 which drives the pivot part 97 in rotation, which drives the actuating arms 96 in translation so as to move the locking fingers 95 away from them. profiles 46 and thus allow the sliding thereof.
- FIGS. 24 to 26 show the handle 18 ejected from a predetermined height which substantially corresponds to the height of the enlarged internal section provided in each sheath (not illustrated).
- the profiles 46 are partially protruding from the lower half-shell 9 (partially illustrated) even though the gripping portion 21 of the handle 18 has not been actuated.
- the cam insert 71 is in the same position as in figure 20 (it has not been rotated) and the tubes 48 are not stressed and the elastic members 62 keep the clamps 50 as close as possible to the sleeves 49 so that the seals 51 are compressed.
- each assembly formed of a section 46, a tube 48 and also a sleeve 49, a clamp 50, an elastic member 62 and a seal 51 has been slid upwards. by the force applied by each elastic ejection member 34, bearing on the respective end piece 35.
- Figures 27 to 29 show the gripping portion 21 of the handle 18 turned into its second position.
- the protruding end 80 of the contact face 79 of the transmission end piece 76 of each cam bearing 71 is then located at a distance from the protrusion 69 of the contact face 68 of a respective pusher 64, while the generally ramped profile of the contact face 79 of this transmission end piece presses on the complementary contact face 68 of the pusher 64.
- the profiles 46 can then slide in the sleeves (not shown) without being hampered by the joints 51, which then serve only to guide the sliding, like the rollers 37.
- the handle 18 can thus be brought into a selected position of deployment.
- the profiles 46 and the clamps 50 are located at a distance from the elastic ejection member 34.
- Figures 30 to 32 show the gripping portion 21 of the handle 18 returned to its first position.
- the gripping portion 21 is therefore no longer in demand.
- each cam bearing 71 The protruding end of the contact face of the transmission end piece of each cam bearing 71 is therefore substantially in contact with the protruding protrusion of the contact face of a respective pusher 64 (as in Figure 20).
- the free ends of the pins 72 have returned to a distance from the shoulder 94 provided on the wall 81 of the respective cam bearing 71.
- the tubes 48 are not stressed and the elastic members 62 keep the clamps 50 as close as possible to the sleeves 49 so that the seals 51 are compressed.
- the compressed seals 51 are found here in the part of the sleeves (not shown) which is not provided with an enlarged internal section so that the seals 51 hold the profiles 46 in position in the respective sleeves.
- the deployable and retractable handle mechanism can be configured so that the second position of the gripping portion and the handle shaft, called the unlocking position, is a stable position, while the first position of the gripping portion and the handle shaft.
- the handle shaft called the locking position, ie an unstable position, the deployable and retractable handle mechanism being further configured to naturally return the gripping portion and the handle shaft to the second position; or each of the first and second positions can be a stable position.
- the deployable and retractable handle mechanism may be generally L-shaped rather than U-shaped, with the grip portion of the handle and the handle shaft forming a branch of the L and the scabbard, channel, and handle. locking / unlocking system that form another branch of the L.
- the grip portion of the handle and the handle shaft may protrude from the upper side wall rather than in a housing thereof. In this case, it may be possible to operate the handle mechanism before the handle is ejected, or even there may not be a handle ejection system.
- the leather goods item may not have a secure lock.
- the article of leather goods may not have a zipper and simply have a clasp.
