Description

Mini hoist, manual, portable, a small footprint The device of the invention is a lifting equipment with the simplest components and designed to equip all kinds of vehicles to facilitate their loading especially a burden such as that of a person with reduced mobility

Specifically in the automotive sector, comfort and safety are the 5 major objectives of all manufacturers including energy saving

Today, motorists use their vehicles a lot and especially to carry out all sorts of races thus being faced with painful efforts related to the loading of the goods such as certain parcels housed at the bottom of a shopping cart.

In this field of loading there is a permanent problem and difficult to surmount that of the transfer of patients more or less disabled from a wheelchair to the seat of a car a real difficulty because of the low access imposed by the opening of doors and often the weight of the patient.

To be the accompanist is obliged to raise completely his patient in order to transfer it to the seat of his car without forgetting to spare it.-

15 In addition to being painful, this action sometimes involves significant muscular strength to lift a patient practically at arm's length because the difficulty lies in the lack of access to the vehicle caused by the wheelchair congestion

Generally one loads in his vehicle burdens compatible as much as possible, with his musculature but at the level of the transfer of patients affected by paralysis 20 the difficulty can be insurmountable because of the weight of the interested party

It is at this level that comes the opportunity to be equipped with the most efficient lifting equipment the simplest it is especially the least bulky

The present invention retains all these parameters in addition to a low weight added to a very small footprint.

In order to achieve this, the present invention is housed as a fixed roof whose reliability is legendary in addition to an affordable cost which fits perfectly into the components of the invention.

There are many lifting equipment in modern industry but they are usually very heavy and too cumbersome in addition to being unsuitable to meet the demands of motorists who a physical disability as a passenger

The present invention takes the form of an inverted U although it can be used in both. Its base receives a tree in which is advantageously moored a strap or a rope or a winching cable at the end of winding This shaft is articulated in two axes located at the base of the U. In any lifting equipment there is an upward movement by all kinds of mechanical or other means in addition to an infrastructure whose importance varies with the lifting power. In all these applications, the management of the fastening is imperative for the safety and the reliability of the concept. The present invention receives at its base on one side a hinge arm having a ratchet with two directions of rotation and another by a brake disk with a ratchet.

In one of the embodiments of the invention, the reciprocating arm is replaced by a crank with or without a ratchet

The present invention favors the use of belts or standard straps very common in the industry and this because of their small thickness and winding without problems. The inertia brake is the anti-return device of the webbing therefore the load has two parts.

Firstly its base which is attached to the tree carrying strap

The second part of a bigger diameter is nestled on the basic disk

Between these two discs is housed a freewheel whose ratchet system is similar to that of a bicycle freewheel. Whenever the webbing shaft is driven by the ratchet lever or the ratchet crank, the inertia brake prevents the shaft from rotating in reverse, which would result in the load being released.

This loosening of the load can only occur if the disc brake 30 is advantageously formed by two jaws which are loosened to order.

In this case the pawl housed between these two discs drives the upper part which forms the brake disc.

This maneuver which consists first of all in reversing the direction of the ratchet which equips the drive lever of the belt carrying shaft or in another application to release it simply implies from this action to release the inertia brake.

Ratchet wheel systems are widely used in industry and there is a range of models that are adaptable in the invention.

The operation of the device of the invention requires to hang generally by means of a strap: the top of the inverted U to a hook or a bracket 10 located upstream. The rotating shaft carrying straps solves the burden retained by the trellis strap In another application of the invention the inverted U is no longer because it works in the other direction

In this case the web carrying shaft forms the top of the device as it is connected to a hook or a bracket or the like. The top of the overturned U that is now no longer connected to the burden

The miniaturization of the invention a mini hoist which allows to win easily a human even very heavy is wanted to facilitate its use in many sectors of activity because in addition it is very light to the point of falling into a blouse pocket 20 or a mini tool kit or a glove box of vehicles.

To lift loads of more than 100 kg up to many tons the industry has made tremendous progress with lifting equipment.

Currently, there are sectors of activity that make it necessary to lift persons with reduced mobility in areas that are difficult to access such as the passenger compartment of a vehicle 25 or the bed of a patient.

The small footprint of the invention added to its cost of production attractive in view of its simplicity all this is a valuable asset for all those who face the often insurmountable difficulties of lifting a person with reduced mobility among other daily chore often pluri The selection of the components which form the device of the invention guarantees its resistance to all tests, notwithstanding its attractive miniaturization intended to facilitate its handling.

The product of the invention does not respond cost-effectively to heavy loads over long lengths.

In return, it becomes the indispensable tool for moving human burdens or other loads on a low height precisely where all that exists in lifting equipment can not access in addition to its unprofitable cost.

The device of the invention comes by its attractiveness and its performances serve the man 10 by replacing his muscles in many cases including the craftsman not to mention all the do-it-yourselfers.

The device of the invention comprises a locking key advantageously housed in a bore made of one in the brake disk and on the other by the arm of the U. This safety key complements the performance of the invention.

In the sector of activity which is related to the craft or other transfers of packages such as household goods or any other commercial vehicles a telescopic tube of the invention is fixed vertically on a door of the van

Its use consists in sliding the lower part of this tube and the keyway 20 when it touches the ground and the three branches that form its support triangle deployed.

The upper part of this tube receives a removable bracket in which circulates a strap whose end allows to bind a burden The U of the invention is placed in the vertical part of this tube and the winch strap 25 for hoisting the load flows in the bracket to the U whose traction lever receives a return angle mechanism to place the manipulator in good conditions The device of the invention is very useful in the sanitary sector A telescopic tube of the invention compatible with sanitary furniture receives at its base a circle with a rubber suction cup and a less important at its top.

A screw with torque limiter makes it possible to put pressure on the two discs A removable and orientable stem as the previous one receives the strap which retains the tree of winching because the U is not reversed any more because its rounded part is connected to the harness compatible that equips the user what has its control levers pulls and brakes within reach.

In hospital beds with a bar that overcomes the bed, the device of the invention can be easily hooked to lift a patient.

In one of the applications of the invention and in FIG. 1; The marks (1) and (2) form the arm of the inertia brake.

The basis of the present invention being miniaturization without jeopardizing performance and safety its main advantage lies in its low weight and easy handling. This small size makes it possible to fix the U of the invention at the bottom of a tube which serves as a washing bend.

In this regard, a telescopic tube of low height whose weight and size are compatible with the performance of the hoist of the invention this tube receives at its base three articulated bars to be foldable from one to the other by 'they are on the ground to serve as a polygon of levitation to the tube

The top of this tube receives a hinge articulated on a hinge and steerable. The rotation of the web carrying shaft raises or lowers the telescopic tube according to the direction of rotation.

This lightweight support pillar pillar receives wheels in certain applications of the invention.

In one of the applications of the invention as indicative and not limiting in the Figure: 1, the marks (3), (4), (5), (23), (24) form the mechanism of the inertia brake

The marks (1) and (2) form the lever of the inertia brake formed by the disc (7) The marks (6) and (18) are the fastenings of the arms of the U, mark (22), on the rings of rotations in which is articulated the shaft (10) carrying strap.

The marker (11) is the light intended to imprison the strap.

The marks (20) and (19) form the lever which drives the rotation shaft (10). The marks (15) and (16) form the ratchet mechanism.

The marks (13) and (14) are part of this set.

The mark (7) is the brake disc which is articulated on the disc (8) with its ratchet wheel

The mark (27) is the key which passes through the reference brake disk (1) in a reference bore (28), to be housed in the arm, of the U mark (29) In the application of the invention the small bulk U allows to accommodate it in a tube often telescopic which serves as a pillar of the invention resting on a triangle levitation and with a swingable and articulated stem

In this application the U is not overturned and the rotating shaft wraps the strap coming from the load through the vertical or horizontal tubing this device is often provided with wheels to move the load.
