Definitions
- the present invention applies to an axle hand trolley and in particular to the rolling chassis for such a trolley.
- a rolling carriage chassis with a handle and a length capable of being easily carried by an adult at arm's length, comprises an axle equipped with two wheels or groups of wheels and on which four substantially upright bars are welded or otherwise rigidly fixed parallel forming two internal upright bars and two external upright bars preferably made of wire or standard metal tube or of a resistant material folded or formed in a general U-shape before their welding or their attachment to the axle.
- Hand carts are widely used by the public worldwide, especially in the urban world which currently represents almost a third of the world's population.
- the trolleys used in many forms, from the individual supply trolley to supermarket trolleys or shopping carts (trademarks) are often as stable at times but as bulky as a wheelbarrow and are, of course, like all products human, not just benefits.
- Known axle hand carts are intended to carry sometimes bulky loads but with a weight limited to about 20 kg at most, corresponding substantially to the muscular capacity of urban users. In some applications, larger loads must not only be pulled, but must frequently climb onto sidewalks and up and down stairs.
- the rolling chassis of a carriage with a pull handle and / or manual pushing, comprising an axle equipped with two wheels or groups of wheels and on which four upright bars are welded or otherwise rigidly fixed.
- the external uprights comprise, in the vicinity of their connection to the axle, a part which is strongly inclined relative to the vertical and of attachment to the axle, so as to allow the entire carriage chassis and the axle wheels to easily pass small obstacles such as sidewalks, stairs during taxiing r a sliding-rolling effect and, on the other hand, in that the internal uprights form, beyond their attachment to the axle and at each end, a curved or hooked part and slightly inclined on the side opposite to the inclination of the external uprights in the vicinity of the axle, to allow the attachment of a load or an accessory or removable part of the chassis.
- the upper part furthest from the axle of the two internal U-shaped uprights protrudes above the crossbar of the U of the external uprights, to which it is welded or otherwise fixed on the side of said curved or hooked part, of a low height by forming a gantry slightly inclined on the side of the curved or hooked part of the uprights interiors, and each of the inner uprights has an inner ring which is rigidly attached thereto on the inner side of the U of the inner uprights and which is capable of receiving one leg of a telescopic sliding handle in U shape with two legs, the leg sliding in a displacement substantially straight in a sliding manner and, if necessary tightened, in a passage aligned with the hole of the inner ring and formed between the transverse bar of the U of the external uprights, and the transverse bar of the gantry slightly inclined of the internal uprights, allowing telescoping the telescopic handle.
- the curved or hooked part of the internal U-shaped uprights is formed by each of the two ends of the branch of the U of the monobloc assembly made of wire or tube of U-shaped uprights, the end which is folded a first time slightly at an angle to the median plane of the U of the inner uprights, is welded or otherwise fixed to the axle according to this bias, forming a small angle of inclination by relative to said median plane of the U of the internal uprights, and which is folded a second time at the free end away from the axis of the axle, that is to say upwards in the service position of the carriage frame, so as to form the part bent by two hooks projecting upwards in service and slightly projecting with respect to the median plane of the U of the interior uprights.
- each of the external uprights comprises, in the vicinity of its transverse bar, at least one ring whose axis of the hole or passage is substantially parallel to the median plane of the U of the uprights exteriors.
- Each of the external uprights can comprise two superimposed rings, formed by welding or other rigid fixing in three zones of a metal wire profile in the general shape of W which forms with its external upright two ring holes of elongated shape in the perpendicular direction. in the plane of the U of the external uprights.
- the two ring holes may have different elongated lengths, the longest being located at the top, that is to say the closest to the crossbar of the U of the external uprights, so as in particular to allow to place in different elongations a hoop or a support frame whose ends are engaged elastically in the holes of the rings.
- the axle hand trolley comprises a trolley frame as described above and is characterized in that it comprises a telescopic handle in the general shape of a U with a crossbar and with two long legs, each of which is provided at its free end with '' a short retaining hook in extension of the handle, constituted by a folding of the end substantially in a plane perpendicular to the median plane of the U-shaped handle, said handle being engaged by each of its legs in the hole of the ring corresponding interior of the interior upright and sliding by each of said legs in an adjusted manner between the U-shaped gantry crossbar of the interior uprights and the crossbar of the U of the external uprights.
- the telescopic handle is easily removable because it is mounted on the carriage chassis by introduction of each of the short hooks into its corresponding inner ring substantially perpendicular to the plane of the interior uprights of the rolling chassis of carriage and then folding the U-plane of the telescopic handle close to the plane of said internal uprights and above (or below) the axle of said chassis, until bringing the crossbar of the handle into contact with the bar transverse of the U of the external uprights, which then makes it possible to push the said transverse bar and the upper part of the long legs of the handle inside the passage left free between the said transverse bar and the transverse bar of the slightly inclined gantry of the internal uprights and having short uprights, and the fact that the telescopic handle is likely to be e disassembled by acting in the opposite direction and, if necessary, to be replaced by another telescopic handle, if necessary longer, or shorter, or more solid, or more rigid, or lighter.
- the hand cart according to the invention can thus comprise removable telescopic handles of different lengths, or resistances, or stiffnesses, adapted to the loads carried by the cart.
- the legs of the telescopic handle can slide tightly between on the one hand the gantry crossbar of the U of the internal uprights whose inclination, on the side of the curved or hooked part, is adjusted to cause elastic tightening and d on the other hand, the crossbar of the U of the external uprights.
- At least part of the respective zones liable to rub during the tight telescoping of the handle can be formed into a flat by any suitable means such as flattening, filing, milling , so as to reduce the wear in thickness of the friction zones and to maintain said elastic tightening over time.
- the telescopic handle is capable of moving by sliding in a short position in which each of the short end hooks of the legs of the handle is supported on the axle or is placed in the vicinity of this axle, the transverse bar of the telescopic handle then projecting slightly or coming substantially at the level of the transverse bar of the gantry of the internal uprights, so as to reduce the size of the carriage or to allow its transport with outstretched arms.
- the telescopic handle is capable of moving in a long position in which each of the short hooks at the end of the legs of the handle is in support or substantially in retaining support on the corresponding inner ring of the interior uprights thereby forming a long transport handle which is made integral with the chassis of the carriage, on the one hand by the support of the short hooks on the two inner rings and on the other hand , by adjusting or the elastic nip between the crossbar of the outer uprights and the crossbar of the inner uprights.
- the trolley comprises a removable hoop formed substantially in a semicircle with ends folded substantially at a right angle and which are snapped, after elastic deformation of the hoop , each in the hole of a respective ring fixed on one of the external uprights, so as to allow the hoop to pivot to retain an object on the carriage while being hooked to the rings of the external uprights.
- the ends of the hoop can be folded outwards and are then latched from the inside to the outside of the U of the external uprights, so as to confirm the latching in case of reaction of the object retained by the roll bar on the trolley.
- the trolley comprises a removable support frame provided with two hooking uprights in folded metal wire or in bent metal tube and at least two crosspieces in wire or metal tube fixed to two 90 ° folds of said attachment amounts to constitute, by upward folding in service of the front folded gantry, a kind of U-shaped box which is, on the one hand, capable of receiving bulky objects such as bundles or wooden logs or stakes and, on the other hand, to rest on the ground at the angle of the front folding in the fold-up gantry
- the support frame comprises, at the 'upper end, in use, of said hooking uprights of short hooks folded back substantially at a right angle parallel to the crosspieces and which are each engaged in a hole in a ring of an external upright of the carriage frame, and one of the sleepers fixed to the base of the hanging uprights is engaged behind the curved or hooked part of the interior uprights, while the other of the two crosspieces of the support frame is arranged on the side
- the hand cart according to the invention can comprise a removable flexible bag made of textile material or otherwise flexible and resistant, housed inside the support frame being, on the one hand, connected at its upper part to the external uprights by two tabs each provided with a ring or passage through which the corresponding short hook passes the attachment amount of the support frame, and on the other hand, connected to the curved or hooked part of the chassis of the carriage, for example by a textile ring overlapping and, on the other hand, if necessary, to the crossbar of the U of the external uprights, for example by a ring with snap closure, the flexible bag being provided, where appropriate, with a closed lid or flap removably by a means such as a hook.
- the invention also relates to a removable telescopic handle for a hand cart and having the general shape of U with elongated legs and made of metal wire, in particular in steel wire of 8 mm in diameter, the ends of the legs of the U being folded at right angles perpendicular to the median plane of the U to form two short hooks.
- the invention also relates to a removable support frame for a hand cart made of metal wire, in particular steel wire 6 mm in diameter and comprising two hanging uprights and a U-shaped box formed by a double fold of the wire constituting a support base on the ground by its angle opposite to the uprights after mounting on the carriage, the box comprising at least two crosspieces at its base, one of which is fixed in the vicinity of the base of the uprights and if necessary , two inclined reinforcing crosspieces connecting each of the two uprights to the U-shaped box at a crossbar, the free upper end (in use) of each of the two hanging uprights being provided with a short hook formed by folding towards inside the end of the upright to allow the support frame to be hooked to a hole in a ring on a carriage chassis.
- the invention also relates to a flexible removable bag for a hand cart, made of resistant textile material or flexible material, waterproofed or not and comprising a cover or flap capable of closing the bag in an easily removable manner and of fasteners, characterized in that that it comprises, at its upper part, laterally on each side, a fastening tab provided with a ring or passage allowing the bag to be hooked by a hook passing through the hole in the ring or passage.
- FIG. 1 shows in perspective from above, of in front and in elevation, a rolling chassis of a trolley according to the invention equipped with a removable telescopic handle and a hoop to constitute a hand trolley with one axle, suitable for transporting a bottle of liquefied gas, of propane or butane, the hoop being mounted in the transport position for a butane bottle;
- - Figure 2 shows the hand cart of Figure 1 carrying a 13 kg bottle of liquefied gas, the assembly being for example placed in the safety position, lying on the floor of the trunk of a motor car;
- FIG 3 shows in elevation, placed in the rest position or waiting for loading on the ground, and in median cross section, the shopping trolley according to the invention made with the rolling chassis of trolley of Figure 1, combined on the one hand with a removable support frame according to the invention which can be used for transporting heavy and bulky parts such as wooden logs, and on the
- the rolling chassis of the trolley of the present invention consists of an axle 1 equipped with two wheels 2 and 3, in particular of the one-piece plastic type with a smooth bearing, which could by example be replaced each by a group of wheels mounted in a triangle of the type commonly used to climb stairs more easily.
- axle 1 On axle 1, are rigidly welded or otherwise fixed, for example in a one-piece mounting arrangement (metal, plastic) or forming (synthetic resin reinforced with fibers) four upright bars substantially parallel in pairs, forming two bars of internal uprights 4, 5 and two external upright bars 6, 7.
- These upright bars are preferably made of metallic wire, in particular round metallic wire of steel suitable for welding, but they can also be made of metal tube or other resistant material (in monobloc version).
- Each pair of uprights is folded or formed in a general U-shape before welding or attachment to the axle.
- the external uprights have, near their welded connection to the axle 1, a part 8 which is strongly inclined with respect to the vertical, which is intended to allow the entire chassis of the carriage and the wheels of the axle to easily cross small obstacles such as sidewalks, stairs during taxiing, by a sliding-rolling effect.
- the strongly inclined parts 8 extend upwards on the external uprights 6 and 7 by a part slightly inclined relative to the vertical and which ensures, as shown in FIG.
- the internal uprights 4 and 5 have, at each end, branches of the U situated in the vicinity of their attachment 10 (see FIG. 1) by welding (or other means of attachment) to the axle 1, a respective curved portion 11, 12 which form two hooks which could be connected to each other by welding.
- These hooks 11, 12 are slightly inclined on the side opposite to the inclination of the external uprights, so as to allow the attachment of a load such as a gas bottle by its lower ferrule (see FIG. 2).
- the upper part of the external uprights 6, 7 and the internal uprights 4, 5 is constituted by a respective transverse bar 13, 14 which forms the bottom of the monobloc U of these uprights.
- the two internal uprights protrude above the transverse bar 13 of the external uprights 6, 7, the bar to which they are welded at 15, on the side of the projection of the hooks 11, 12.
- each of the interior uprights 4, 5 comprises, on the interior side of the U of these interior uprights, an interior ring 19 rigidly fixed (welded) to the interior uprights.
- each of the legs 16 and 17 can thus slide in a substantially rectilinear movement, slidingly in the passage formed between the crossbar 13 and the upper crossbar 14, to allow the upward and downward movement of the figure of the telescopic handle 18.
- each of the legs 16 and 17 can be clamped between the transverse bar 13 of the external uprights and the transverse bar 14 of the inclined gantry of the external uprights.
- each of the short uprights 4a, 5a (of the respective interior uprights 4, 5) of the kind of gantry constitutes, with respect to the weld 15 connecting to the bar 13, a bending spring rod anchored or embedded in door-to-door -false on the crossbar 13 of the external uprights.
- the handle 18 which must have a certain rigidity is preferably made of steel wire 8 mm in diameter and has, at the lower ends (in the drawing) of the legs 16 and 17, parts folded substantially at right angles and perpendicular to the median plane of the U to form two short hooks 21 and 22. These hooks 21 and 22 abut on the inner rings 19 when the telescopic handle 18 is pulled upwards, so as to limit the elongation of this telescopic handle 18 and to allow it to pull energetically on the uprights interiors 4, 5 firmly connected to the entire carriage chassis.
- the telescopic handle 18 To introduce the telescopic handle 18 in position in the carriage chassis, one begins by introducing the short hooks 21 and 22 into the rings 19 by arranging the plane of the U of the handle 18 in a manner substantially perpendicular to the plane of the interior uprights 4, 5 and then folds the plane of the U of the handle 18 close to the plane of the interior uprights 4, 5 by bending the legs 16 and 17 by bending the end of these legs over the first folds 23, 24 to the part lower in the drawing of the interior uprights 4, 5 and above the axle 1 until the transverse bar 20 of the handle 18 comes into contact with the transverse bar 13 of the external uprights 6, 7, which then makes it possible to push the crossbar 20 and the upper part of the legs 16 and 17 of the handle 18 inside the passage left free between the crossbar 13 and the inclined gantry with upper crossbar 14 and neck posts rts 4a, 5 a.
- the telescopic handle 18 can easily be removed by acting in the opposite direction to what has just been explained for mounting.
- we can have handles of different lengths a relatively short and space-saving telescopic handle being for example intended for urban use of the trolley, while a very long and bulky telescopic handle (two meters long for example), can be used to move very large loads (for example 200 Kg of fertilizer) in the countryside on very irregular rolling.
- the handle 18 easily removable and adaptable (except for the round wire or another section which must pass through the rings 19 and between the transverse bars 13 and 14) thus gives, to the carriage frame and to the hand carriage using this chassis, a relatively universal character.
- the passage aligned between the rings 19, the crossbar 13 and the portal crossbar 14 is slightly less wide than the overall thickness of the handle 18 initially defined by the circular cross section of the wire in which is formed the handle 18.
- the short hooks 21 and 22 are oriented towards the rear, that is to say on the side opposite to the hooks 11, 12.
- it can be provided, as shown in section in FIG. 10, in the central zone of the bar 20, a crushing of flattening 29 which causes the bar 20 to swell 30 which is likely to come into retaining support on the bar 14 to limit the descent of the handle 18 when the telescope in the lower position allowing the carriage of the carriage "at arm's length”.
- the folds 23, 24 are extended by the folds which form the hooks 11 and 12 which move away from the axle 1 by forming a small angle of inclination relative to the mean plane of the internal uprights 4, 5, the end of the hooks 11, 12 lying thus projecting from this mean plane for hooking and wedging in an angle an element to be supported such as a gas cylinder base ferrule or a hanging bar.
- FIGS. 1 and 4 are oriented slightly at an angle relative to the median plane of the internal uprights, so as to also pass at an angle above the axle 1 to which they are welded at 10 (indicated in FIG. 1).
- the folds 23, 24 are extended by the folds which form the hooks 11 and 12 which move away from the axle 1 by forming a small angle of inclination relative to the mean plane of the internal uprights 4, 5, the end of the hooks 11, 12 lying thus projecting from this mean plane for hooking and wedging in an angle an element to be supported such as a gas cylinder base ferrule or a hanging bar.
- each of the external uprights 6, 7 comprises, in the vicinity of the crossbar 13, two rings formed by welding in three zones 31 of a profile 32 of wire in the general shape of W , so as to form two superimposed rings 33 and 34, the holes 35 and 36 of which have an elongated shape in the direction perpendicular to the mean plane of the external uprights.
- the length of the elongated shape of the upper hole 35 is greater than that of the lower hole 36, so as in particular to allow a hoop 37 to be placed in the different elongations (see FIG. 2) or a support frame (see Figure 3).
- the profile 32 can be replaced by a single ring welded to the external uprights near the crossbar 13.
- the trolley hand formed by the carriage frame comprises a removable hoop 37 in the general shape of a semicircle.
- This hoop also shown in front view in FIG. 6 comprises a part 38 in the general shape of a semicircle and intended to come into contact with the cylindrical external surface of a bottle such as the gas bottle 39 in FIG. 2.
- the part 38 is extended by substantially straight parts 38a, the free ends 40 of which are folded substantially at right angles inwards according to FIGS. 1, 4 and 6 and are intended to be snapped on, after elastic deformation by opening the arch 37 , each in a corresponding hole 35 or 36 of one of the rings 33, 34 fixed on one of the external uprights 6, 7.
- the central part of the hoop 37 has a rounded protuberance 41 formed by bending the wire of the hoop and which makes it possible to exert a large locking or unblocking force when the hoop 37 is mounted wedged on the gas bottle 39.
- the arch 37 can pivot forward to cover and hold the gas bottle 39, or else backwards to release this gas bottle.
- the free ends 40a of the arch 37a can be folded outwards.
- FIG. 2 shows a propane gas bottle 39 mounted on the trolley according to the invention when the trolley is placed in the safety position, lying on the floor of the trunk of a motor car.
- the lower or base ferrule 42 of the bottle 39 rigidly fixed thereto by welded lines bears on the hooks 11, 12 while being retained and therefore hung between these hooks 11, 12, and the internal uprights 4, 5.
- the rounded 43 the upper cap of the bottle 39 is capable of coming to bear on the transverse bar 14 of the interior uprights 4, 5 when, due to the lying position of the bottle 39, the ferrule 42 comes off the hooks 11, 12.
- the bottle 39 is thus retained axially. If the propane bottle 39 is replaced by a less tall but substantially the same diameter butane bottle, the transverse bar 14 is still capable of retaining the bottle axially after its axial displacement when it comes to rest on the ground 9 in the position shown in Figure 3.
- the strongly inclined part 8 of the external uprights 6, 7 takes off the wheels 2, 3 from the ground in the supine position of the carriage carrying the gas bottle.
- the carriage frame as shown in FIG. 1 can receive a removable support frame 44 shown in isolation in FIG. 5.
- This support frame 44 consists of two hooking uprights 45, 46 formed in a single piece wire and which are folded two times substantially 90 ° to form at the front a kind of retaining gantry consisting of two short uprights 47, 48 and a crossbar 49.
- the short uprights 47, 48 are connected to the hanging uprights 45, 46 by bottom bars 50, 51 formed during the double bending at 90 ° of the bottom uprights which form a sort of U-shaped box.
- This U-shaped box is reinforced and stiffened transversely by at least two crosspieces made of wire or tube.
- a first crosspiece 52 is welded to the two attachment uprights 45, 46 in the vicinity of their first folding at 90 ° while, according to the embodiment shown, a second crosspiece 53 is welded to the bottom bars 50, 51 in the vicinity of the middle of these.
- the second cross-member 53 is formed of a wire bent in a U which forms two inclined cross-members 54, 55 of lateral reinforcement, also welded to the attachment uprights 45, 46 at a low height above the first cross-member 52
- the inclined crosspieces 54, 55 can fulfill two functions: either retaining a rectangular container laterally as a bottom support on the crosspieces 52 and 53, or retaining long objects such as wooden logs to prevent them from coming to rub on the wheels 2 and 3 of the carriage chassis.
- the attachment uprights 45, 46 comprise, at each of their upper ends (in service) a short hook 56, 57 folded substantially at a right angle parallel to the crosspieces. As shown in FIG.
- each of the short hooks 56, 57 is engaged in a hole (preferably the upper hole) 35 or 36 of the superimposed rings 33, 34.
- the support frame 44 is mounted on the carriage chassis by engaging, on the one hand, the crosspiece 52 at the interior corner of the U behind the hooks 11 and 12, and on the other hand, each of the short hooks 56, 57 of the hooking uprights 45, 46 in the corresponding hole 35 of the superimposed rings 33, 34. The support frame 44 is thus held firmly secured to the carriage chassis. As can be seen in FIG.
- the support frame 44 which in this figure has an additional cross member 58 at the foot of the short uprights 47, 48, is capable of receiving and therefore of carrying bulky and relatively heavy objects such as stakes or cans of water or fuel, preferably rectangular, but also wooden logs (shown schematically in thin lines 59) significantly longer than the width of the support frame 44, the inclined crosspieces 54, 55 moving them away from the rubbing contact with the wheels 2, 3.
- the carriage chassis When the carriage chassis is equipped with the support frame 44, the latter may, during its loading, bear on the ground at the angle 60 of upward folding of the front folding in portal frame 47 , 48, 49.
- the angle 60 is precisely reinforced by the cross member 58 in the embodiment of FIG. 4 but this cross member is not useful in all cases.
- the cart comprises a flexible bag 61 made of textile material or otherwise flexible and resistant, waterproofed or not.
- the bag 61 is housed inside the support frame 44, as shown in FIG. 3, being connected at its upper part to the external uprights 6, 7 by two tongues 62 provided with a ring or resistant passage through which passes the short hook corresponding to 56 or 57 of the hanging amount.
- the bag 61 is further provided with a cover or flap 63 removably closed by any means such as an attachment 64.
- the bag 61 comprises a textile ring 65 which, at mounting on the carriage frame, overlaps the hooks 11, 12. As can be seen in FIG.
- the lower part or bottom 66 of the flexible bag 61 is supported on the bottom of the support frame 44, namely mainly the cross member 53 and incidentally the angle crosspiece 52 and the bottom bars 50 and 51.
- the bag 61 may include a textile ring 67 for connection, for example by hooking, to the bar transverse 13 of the external uprights 6, 7.
- the removable flexible bag 61 can be made of any suitable flexible and resistant material: textile, resistant plastic material or reinforced with fibers, waterproof or not waterproof and it can include a handle i ndividible allowing to carry it when it is not mounted on the hand cart.
- the trolley frame according to the present invention does not stand upright when isolated, but it can be placed against a wall or hung by the crossbar 14 of the gantry or the transverse bar 13.
- the trolley chassis equipped with the roll bar 37 carries a full or empty gas bottle, such as bottle 39
- the center of gravity of the assembly of the bottle 39 and of the carriage is thus placed above a lifting triangle delimited by the two carrying wheels 2, 3 on the ground and the carrying of the outer rim 42a on the ground and the together does not tip over.
- This alternating support wheels 2, 3 / parts 8 limits the shocks to the obstacle by a rolling-sliding effect.
- the connection of the external uprights 6, 7 to the axle 1 by the strongly inclined parts 8 also makes it possible, as shown in FIG. 2, to take off the wheels 2, 3 from the ground when the carriage chassis or the equipped carriage is placed on a bearing surface 9, in particular in the position of least encumbrance of the telescopic handle.
- the trolley chassis according to the invention and the hand trolley which it forms with its removable accessories is subjected to opposite constraints: it must be compact in the storage position, in particular in the boot of a vehicle and it must have a relatively large length at the handle to transfer the load mainly on the wheels.
- the hand cart according to the invention must also satisfy another often overlooked imperative: it must roll on various grounds.
- FIG 11 an assembly of the wheels of the hand cart according to the invention ensuring a good compromise space / quality of travel.
- the massive plastic wheel 3 is held on the axle 1 connected to an inclined part 8 welded at 8a, by a hooking cover 68 also indicated in FIGS. 1 and 4 and whose claws are attachment 69 of hardened hard steel penetrate into the metal, softer or made softer by a "blow of flame", from the axle 1.
- the hub 3a of the wheel 3 is thus retained in abutment between the inclined part 8 and the attachment cover 68 while being capable of sliding slightly between these two stops.
- the hub 3a of the wheel 3 has a long length L1, for example greater than the length L2 of the tread of the wheel, and the normal play 70 between the hub 3a of the wheel and the axle 1 is large, of the order of 2 mm for an axle of 10 mm in diameter. Thanks to these provisions, wheels of reduced dimensions (for example 100 mm in diameter) for the trolley have good rolling qualities on various soils, including loosely packed soil, while limiting the rolling shocks absorbed in part by the play 70.
- the present invention is not limited to the embodiments described and shown, but it is susceptible of numerous variants easily accessible to those skilled in the art without departing from the spirit. of the invention.
