FR2778071A1 - LUGGAGE WITH SLIDING HANDLE - Google Patents

Abstract

A baggage with sliding handle of the type comprising a handle (5) integral with two rods (4) which slide in two tubes (3) fixed to the baggage (1), these rods (4) being immobilized in the tubes (3) in the at least two positions, an extended position and a retracted position by locking means. Each locking means is constituted by a hydraulic lock (10) connected by a hydraulic pipe (15) to a hydraulic pump (20) actuated manually.

Description

LUGGAGE WITH SLIDING HANDLE

  The present invention relates to luggage with a sliding handle, that is to say

  tell a piece of luggage which has on the one hand at least at its base a pair of rollers and on the other hand at its upper part a handle which can slide at least between an extended position and a retracted position and can possibly occupy intermediate positions . Handles of this kind must be able to be immobilized in any

desired position.

  For this purpose we use either elastic systems or locks

I0 mechanical.

  The elastic systems are, for example, a ball constrained by a spring coming to be housed in an appropriate recess: a strong traction or a strong pressure causes the ball to come out of its housing by compressing the spring These devices

  have the advantage of simplicity but are unreliable.

  Lock systems consist of at least one lock placed in one of the sliding rods, and preferably two locks, one in each rod, c. es latches being controlled by a mechanism located in the handle. The disadvantage of these devices is that they require motion return rods which are

  fairly complex, fairly heavy and subject to rupture.

  The subject of the invention is a bag with a sliding handle comprising a handle integral with two rods which slide in two tubes fixed to the baggage, these rods being immobilized in the tubes in any desired position, in particular in at least two positions, an extended position and a retracted position, the means by which the rods are immobilized in their tubes being hydraulic means actuated by a pressure source, possibly with a lock controlled by

  a hydraulic piston connected by a hydraulic line to a pump.

  According to other possible characteristics of the invention: the means for immobilizing the rods in the tubes consist of deformable membranes swollen by the hydraulic liquid coming from the pressure source,

  - each locking means is constituted by a hydraulic lock connected by a hydraulic line to a pressure source such as a manually operated hydraulic ponp, - the pressure source and a pump placed in the handle, S - the hydraulic pump is a pump pistons, the piston of which is actuated manually by a lever, - the hydraulic pump is a diaphragm pump, - which each lock comprises a finger secured to a piston controlled by a rssor, - the lock comprises a finger secured to a membrane deformable,

  - the pump and the valves are connected by a flexible hydraulic pipe.

  By way of nonlimited example, the following drawings have been shown: - Figr 1: a girral view of a baggage item with a sliding handle, - Figure 2: a detail view of the hydraulic device

  I5 - Figwe 3: a large-scale detail view of a vrmr.

  Referring to Figure 1, we see that the luggage 1 has two rollers 2 and is provided cn more than two tubes 3 in which slide two tigs 4 connected to

a handle 5.

  Referring to FIGS. 2 and 3, it can be seen that each sliding ige 3 comprises, near its end, a vmrou 10 constituted by a cylinder 14 in which a piston 13 fitted with a finger moves. The piston 13 is subjected to the action of a spring 12. When the hydraulic fluid arrives in the cylinder 14 through the pipe 15 the piston 13 moves back cn compressing the spring 12 and the finger 11

  clears the hole 16 min in the wall of the tube 3.

  The tube 3 compoeteau minus two orifices 16: one which corresponds to the retracted position of the rod 4 in tube 3 and one aure which corresponds to the output poion. It is however possible to have other ofices 16 which will define as many positions in diair

  The liquid somu Pressure anivanmt by the pipes 15 to each of the verrmus ect supplied by a manual pump which can be of any type known Dams the example shown, the hydraulic pump 20 comprises a piston 21 which ,, in pn t in a cylinder 22 , expels the hydraulic fluid dams ks caalio 15. The piston 21 is brought into action by a lever 23 actuated manually. Slon moule variant of realization, ls pisto 13 and 21 can be replaced by defomable mebnamms so that the hydraulic circuit is perfectly

waterproof, safe from leaks.

  o10 The pump 20 is preferably placed in the handle 5 but can be placed in any other place It can also be actuated by any means

  appropriate; the pump being able to be any source of applied hydraulic pressure.

  Dam reexamines meadows and describes, we have decreed means of positive anchoring; but it was possible, instead of such means formed by bolts penetrating into orifices, to be used without exiting from the pressure blocking means, exerted on the rods 4 by a united swellable detonable membrane

  by hydraulic fluid from the poressiLn source.
