Abstract

The invention relates to a manual handling trolley consisting of a support frame (1) on wheels (15) and directional wheels (16), surmounted by rails (12) adjustable in height and a merchandise support tray ( 2), itself equipped with rollers (3) non-directional. The tray (2) rests on the frame (1) and can, once unlocked, be introduced manually, with its contents in a vehicle trunk, or extracted from it. The invention allows, in addition, the transport of the carrier frame without much space since the U-shaped structure will embed the tray (Figure 2) and its contents after being carried and manually entered into the vehicle of the user. This trolley is particularly intended for craftsmen who are obliged to carry tools and raw materials necessary for the execution of their activity from the parking place of their commercial vehicle to the intervention site and vice versa. Beyond the saving of time achieved, the user saves his physical forces since the invention will allow him to exonerate handling operations related to the carrying of loads for loading, unloading, and transport goods on foot .

Description

The present invention aims to allow a man working alone to load and unload a transport cart with its contents of goods in the trunk of a utility vehicle without having to handle the goods.

The device is in the form of a conventional industrial truck. It consists of two distinct elements. On the one hand, a mobile platform with wheels, intended to support goods, and secondly, a carrier frame of said plate, itself equipped with wheels and wheels.

The undercarriage is surmounted by rails on which rest and are guided the wheels of the plateau. These rails are set before any use at the height of the loading threshold of the vehicle used. The goods to be transported are placed on the cart tray. Thus, when the chassis is positioned in abutment against the bumper of the vehicle, and that its casters are locked, the tray can be unlocked from the chassis and transferred with its contents by a manual action in the trunk of the vehicle used, conversely to unloading.

For the transport of the chassis, its lightweight U-shaped structure allows it to be lifted manually and introduced into the vehicle by embedding the tray and its contents. The vehicle used must for this to offer unobstructed access to its loading threshold at the trunk.

The present invention will therefore allow its user to exonerate previously hitherto unavoidable tasks of handling related to the carriage of goods for the loading or unloading of safe. Beyond the time saved, the operator saves physical efforts harmful to his muscle health. Operating from outside the vehicle, the user works in a standing position. In addition, the tray trolley principle will allow its user to access the contents of the trolley at a later time without having to bend down to ground level.

The handling and transport of heavy or bulky goods from the parking place of a vehicle to the site of intervention are to date and traditionally carried out using a devil-type tool or folding light truck. These tools, however, do not exonerate the user to carry these goods from the trunk of a vehicle to the ground level to position them on the devil or the light truck, and vice versa, the devil or light truck folding up to to the chest.

It is also very common to note that the loading or the unloading of a utility type vehicle requires that one is introduced in his chest obliging the operator to realize the rise or the descent of a march of a value between 50 and 70 cm, depending on the vehicle model. This operating height corresponds to the loading threshold of a utility-type vehicle, and obviously does not prove to be suitable for a man, especially when he has to enter or leave the vehicle with loads carried. This is the reason why we meet certain vehicles equipped with an additional access step at the bumper. This is also why small trolleys have been developed for transporting goods by rolling them and whose mechanisms allow the complete loading or unloading of the device with its contents in the trunk of a vehicle. These devices require either lifting mechanisms to allow the introduction or extraction of the system and its contents in a trunk of a vehicle, as proposed in documents 2,836,445, 2,184,205 or 2,997,365, either folding mechanisms of the support legs on the model of the ambulance stretchers as proposed in documents 2,781,745 or WO 2011065808, or finally the dismemberment of the carrying structure of a basket to allow it to be stored in the vehicle as proposed in document 2,880,606.

The device according to the invention overcomes these disadvantages.

It comprises in fact according to a first characteristic a frame (1), provided with wheels (15) and wheels (16), surmounted by two rail tracks (12) on which rests a plate (2), a carrier for goods, itself even rolling after being unlocked, the two elements being intended to be manually introduced by its user in a utility vehicle with a minimum of effort and space.

According to particular embodiments: - a tray (2) support goods, provided with fixed rollers (3), is rolled, after being unlocked, on the rails (12) which surmount the carrier frame (1) and to be manually transferred using handles (4) from the carrier to the trunk or vice versa. - two rail tracks (12) on which the plate (2) is contained (18) and can move, surmount the carrier frame (1) and are adjustable (25) in the legs of the frame (13) (14) for be fixed at the same height as the loading threshold of the vehicle used. - The structure of the carrier frame (1) with its rails (12) is U-shaped and a slightly greater width (17) than the tray (14) so that the chassis encases the latter with its content to allow transport with minimum handling and bulk. the rails of the carrying frame (12) are extended by removable rail elements (20) allowing, when they rest on the edge of the trunk of the vehicle, the passage of the plate (2) between the support frame (1) and the chest and vice versa. hinges (21) connect the rails of the chassis to the extension rails in order to allow the passage of the platform under all circumstances, especially when under the effect of the weight, the level of the loading threshold of the vehicle is lowered; the hinges (21) will allow the extension rails (20) which rest on the chest to accompany these level variations. - The position of the hinges (21) connecting the rails (12) to the extension rails (20) are slightly recessed, vertically (28) of the bearing axis of the wheels (15) of the frame to ensure the stability of the device during tray transfer operations and prohibit any risk of tipping. - The wheels (15) and wheels (16) of the frame (1) and the plateau rollers (3) are offset from their structure, firstly in order to bring great stability to the device, but also to minimize the congestion of the device when the chassis fits the ground plate in the vehicle since the structure of the frame (1) will register vertically casters tray. two removable plates fixed at the rear to the plate (6) pivot vertically to lock or unlock it, or to the frame when these plates bear against the outer part of the rails (12), causing at the same time the possibility moving the carriage, either in the trunk when they are positioned in grooves (7) present in the floor (8) of the trunk of the vehicle; in upright position the removable plates unlock the chassis or trunk tray for transfer operations. - Welded bolts at the bottom and front of the plate (11) are housed in two hook-shaped stop plates (29) welded to the inner edges of the rails (12) of the frame (1), fully solidifying the plate (2). ) on the carrier frame (1) for moving the carriage device.

These drawings are used to describe an example of non-limiting use of the carriage.

According to Figure 1, the carriage has two distinct parts, namely a wheeled tray (2) merchandise support intended to be introduced or removed from the trunk of a utility vehicle after being locked or unlocked a carrier frame (1) on which it rests, and a chassis provided with wheels and wheels surmounted rails to be also introduced into the trunk of the vehicle by embedding the shelf goods.

According to FIG. 3, in order to enable the operations of transferring the platform (2) from the carrier chassis (1) to the trunk or conversely, the operator must firstly use the height of the loading threshold of his vehicle to to adjust the rails (12) of the chassis to the same level (25). This setting will only be changed if the operator changes vehicles.

This operation is done in the absence of the tray. For this, the feet of the rail structure fit freely into the frame structure, and holes (13) are provided and spaced vertically in the feet of the rails to receive a locking pin (14).

It is thus possible to adjust (25) the height of the chassis rails to the height of most existing utility type vehicles, in a range of 45 to 70 centimeters from the ground.

To lock the tray in the trunk of a vehicle equipped with a wooden floor (8), it will be necessary to make two grooves (7) of a depth of 1 cm, a width of 5 mm, and long each 20 cm. Depending on the vehicle used, the slits must be made at a sufficiently distance from the doors so that the entire device (floor plate + chassis loaded) once loaded into the vehicle allows the closing of the doors.

If the vehicle is not equipped with a wooden floor, a board of reception is to be installed; this board of agglomerated wood is intended to be fixed to the ground of the vehicle by screws. The board is to be positioned in the trunk of the vehicle under the same conditions as above, and taking into account the presence of the bleeding in the board.

Carrying out the kerf or securing the supplied landing board should also be determined by the depth of insertion of the extension rails (20) into the trunk when the carriage is abutting against the vehicle bumper.

According to Figure 8, the tray transfer operations require positioning the frame abutting against the vehicle bumper and blocking its directional wheels (16) with the brake system (23). The abutment contact of the device with the bumper is secured by the presence of a protective foam (24).

According to Figure 8, when the device is in abutment with the bumper, the fixed front wheels (15) of the frame (1) are positioned under the vehicle.

According to Figures 4 and 8, to be introduced into the trunk, the plate (2) must be unlocked from the frame (1) at the plates (6) and pushed manually. In this movement, the plate rolls on the rails and its passage tilts the extension rails held in vertical position by springs (22) to the trunk. The rails come to rest and rest on the wooden floor of the vehicle (8).

Once introduced into the trunk, the plate locking plates (6) are manually folded by a vertical rotation movement to lodge in the grooves (7) present in the wooden floor of the vehicle (8). The tray is then locked to the ground.

Before the introduction of the frame into the trunk, the extension rails (20) are raised in the vertical position and thus held by the springs (22).

Then according to Figure 9, the operator grasps the lifting handles (26) of the chassis, raises the rear of the chassis retaining the large wheels (15) on the ground, just put the knee or upper leg support against the lifting foam (27) of the frame, then by a movement of the lever lifts it completely until the large wheels at the edge of the box. This method and the light structure of the chassis make this manipulation very easy and fast.

The chassis is finally introduced into the trunk by embedding the tray and its contents, by rolling it on its front wheels (15) until it stops against the handles of the plate (4). At the end of this step, the directional wheels (16) of the chassis having been kept in the safety position (23), the device is fully secured for transport in the vehicle.

According to Figures 6 and 12, to allow the frame to embed the tray and its contents, the frame structure has a U-shaped flat. Thus, according to Figures 7 and 11, the volume of goods (14) placed on the tray (2) must not exceed the width of the tray. For this, two thin plates (5) constitute the edges of the plate in all its length. They materialize the limit of the available cargo space (14) for the goods on the board.

According to Figures 5 and 7, the four fixed wheels (3) of the tray are offset to rest on the rails of the frame. Similarly, the wheels (15) and wheels (16) of the frame are offset to allow the embedding of the tray with a minimum of space. Thus, the wheels (15) and wheels (16) of the chassis do not meet the wheels of the tray on the ground. The diameter of the fixed rollers (3) of the tray is less than the height available under the structure of the undercarriage. The unloading operation of the device will be in the reverse order of the loading steps described above. The chassis, whose directional rollers (16) have been retained in the locked position (23) is removed from the boot and positioned in abutment against the bumper by grasping its handles (26) and rolling it on its front wheels (15).

For extraction of the trunk tray, the extension rails (20) are folded manually and placed on the edge of the trunk. The rails must fit into the exit race of the fixed wheels (16) of the plate.

According to Figures 2 and 11 the tray is unlocked from the ground by raising the plates (6) housed in the groove (7) of the wooden floor (8) and extracted manually using the handles (4) of the tray in s' ensuring that the casters fit on the rails. These same handles (4) are also used for the movements of the complete device as a transport trolley.

According to Figures 1 and 4, when the tray is introduced to the stop on the rails of the frame, and without any additional manipulation is necessary, the plate is secured to the frame. Indeed, parts welded to the plate (11) and (9) are housed in receiving and locking parts (10) and (29) welded to the rails. The two elements thus assembled, the carriage is structured, the tray can not lift from the chassis, the chassis can not deviate during travel.

According to Figures 1, 4 and 5, the plate (2) is finally locked to the frame (1) when the two removable plates (6) present at the rear of the tray are folded manually to register in support against the outer part rails (12) of the carrier frame. The tray is then fully secured to the frame, the movement of the carriage is possible.

When the plates (6) are in the high position, the plate is unlocked, it can roll on the chassis rails to the trunk or vice versa.

To ensure the transfer operations, the two rails (12) are provided with outer edges (18) which guide and maintain the tray.

For the displacement of the entire device, and to enable it to borrow rough terrain, the chassis is provided with large wheels (15) fixed at the front and directional wheels (16) with locking system ( 23) at the back.

According to Figure 6, the frame structures and rails are composed of welded elements. The welds give the truck great strength for the transport of heavy loads. By way of non-limiting example, the device will have dimensions whose total width (19) allows the passage of doors and lifts. In addition, the user will have the possibility according to the space available in his vehicle to equip his vehicle from 1 to 6 trays, with only one undercarriage,

Furthermore, according to a variant not shown, the frame may be equipped with a winch provided with a cable and a hook for the purpose of extracting the trays.

The device according to the invention will be particularly suitable for carrying out repetitive operations of deliveries of various goods or the transport of heavy equipment such as compressors, machine tools of building sites, various boxes, bags of raw materials, such as bags. cement ... A craftsman working alone will be able to exonerate himself from the tasks of loading and unloading his vehicle, as well as the carriage of goods between the parking place of his vehicle and his intervention site.
