EP2502866B1 - Hose cart with double reel and hose connector - Google Patents

Description

The invention relates to a hose reel with double reel and hose connector - especially a hose reel with two parallel drums and hose connectors for water technology.

Hose trolleys are used wherever medium-carrying long hoses are used as a means of transport for gases, liquids or powdery or pasty / pulpy substances - as a storage location and as a means of transport; These may preferably be air, gas or water hoses. The cable drum car is a related device in the field of electrical installation and communication technology, depending on the size and equipment provided with manual or motorized drive. In the case of the pipelayer, on site the pipe-wound roll is manually or motorized for installation, e.g. Today of many plastic piping for receiving gaseous or liquid media, or even cables and / or lines of electrical engineering or telecommunications. If the hoses are to be kept as compact as possible in the unused state and free from drilling and tension, and if they are to be available quickly in the right place for use, the use of the hose trolley is indispensable. Likewise, the rapid media-free storage of the gas or liquid transport means for the purpose of keeping importance by orderly winding with accompanying emptying. Newer devices are also provided with a built-up depending on the purpose fitting that fulfills certain functions of handling the hose in conjunction with the hose cart.

With the increased use of hoses - initially of rubber hoses, then increasingly of plastic elastomer hoses with different fabric layers - also multi-layered constructed - also the demand for suitable transport and storage products grew. While first versions of hose carts were very similar to a flatbed vehicle, moved in a further step, the drum in the field - however, as a rewinder independent of the hose - and further developments create a functionality between the hose and drum of the hose cart, in the media-carrying fittings firmly with the drum communicate and serve as a connector and link.

Following technical progress, the first transport trolleys were constructed of wood and metal - initially made of profile iron in combination with wooden parts, later on straight and curved pipe fittings with iron fittings, in which case the fittings were increasingly replaced by plastic injection molded parts. With increasing climate / weather resistance, all-plastic equipment was developed and manufactured with the renewed goal of being able to disassemble and build from a transport-friendly packaging - marketed through a specific distribution channel. However, new all-metal versions are also commercially available.

In the following, the prior art of hose reel with double reel and hose connector - especially of hose reel with two parallel drums and hose connectors for water technology appreciated; According to the prior art, depending on the application reference, a variety of types of hose reel with double reel and hose connector - in particular of hose reel with two parallel drums and hose connectors for water technology in use.

I dual role

The German utility model DE 76 34 684 recommends a three-wheeled, rubber-tyred cart with flatbed - constructed of profile iron with wood panels, in which another lockable box for irrigation accessories is provided - on a roof-shaped Eisenstellage take place whose rooftops in the direction of rotation take up rotary axes, the two, parallel and transverse to Travel direction in diameter of different sizes, spaced apart from each other by plastic bushings, individually rotatable wood, metal or plastic drums for hoses record, the hose beginning on the drum axis and the hose end are clamped surface on the drum side.

The drums are pure hose transport means, which take up the hoses by winding; Water technical valves, which are in connection with the hose trolley or hose reels, are not provided.

II hose drum as a chassis

In the utility model DE 18 71 573 it is a hose reel for the irrigation technique, in which the hose take-up roll also serves as a roller. A continuous tubular bracket is shaped so that it represents a driving handle when the roller keeps in contact with the ground and forms a support bracket, when the role lifted from the ground serves as a hose drum. The axis of rotation is formed as a water-carrying through-going part with two hose connection nipples, an external connection, via which water is supplied by means of a hose, and a drum connection, which forms the connection for the winding hose.

The course of the water hose from the drum connection, through the Aufwickelzylinder in the first Aufwickellage is not shown, and thus it is not apparent whether a kinking freedom of the hose is given. Is the external connection not rotatably mounted tight, the hose cart can not be moved when connected here hose.

The utility model DE 70 15 862 also describes a hose trolley for land and garden irrigation, consisting of a tubular frame and a thereto rotatably mounted, the hose receiving drum. The peculiarity lies in the fact that the hose drum on the one hand represents the Aufwikkelvorrichtung, the tube frame has a stand, and on the other hand is used to process the hose cart. The drum-receiving axis of rotation of the tubular frame is provided at both axial ends with threads for receiving threaded nipples and can be used as a cable connector.

Since the entire hose carriage is made of pipes, webs and skids according to an open design, the tube connected hose connected kink free to the first layer winding or the order of operations is changed: first wind, then connect.

III hose trolley with chassis

The utility model DE 18 81 979 and DE 18 81 980 provide a substantially provided of metal pipes and own chassis, a sack truck similar to hose reel, with pointing in the direction of travel water-bearing axis is mounted at about halfway between the chassis and handle, which also made of metallic sheet open, rotatably mounted double, with the water-carrying axle releasably connected reel with twist grip carries, so that the reel transverse to the direction of travel wraps.

The backup of the reel takes place by means of an M-shaped clamping spring which rests with its legs on the circumference of the bushing under a press fit and with its lying between the legs curvature transverse to the water-bearing axis slot in the wall of the bushing passes.

Furthermore, the tubular bearing for the water-bearing axis on two opposing, obliquely downwardly directed, semi-tubular legs, with which the upwardly directed legs of the chassis of the hose cart are integrally connected. Another, located in the direction of travel end of the water-bearing axle bushing serves as a connecting piece for the wound on the reel hose, which is guided for the first turn of the hose winding from the outside through the side windows of the reel without kink protection inwards.

The utility model DE 19 48 674 represents a tubular steel easily built hose reel with its own chassis, the side view of the handle starting, a standing 'V' and then a lying 'V' recognize, with in the sink of the first 'V' perpendicular to the depth of rotation with four parallel wheels / rollers, rather rollers, mounted and in the top of the second 'V' double-sided pivot bearing, which accommodate the transverse to the direction of travel drum. While a drum rotary bearing connects a hand crank with the drum, the opposite rotary bearing has a sealed stuffing box with double-sided Hose connection piece, with the drum-rotating inner socket pointing into the drum interior.

The all-metal hose trolley is equipped with a separate chassis with roller-like wheels / rollers; Since the hollow cylindrical drum body is shown completely closed, it is not clear how the water hose from the inner tube (in the drum) through the cylinder wall of the drum is guided without kinking to the outside for winding.

Subject of the utility model DE 19 88 159 is a simple metallic hose carriage with its own chassis of substantially round tube, the bottom side of a near the apex area, the wheels / rollers U-shaped frame is made with flattened bent to the ground free leg ends and also mounted in the apex region perpendicular to the frame frame plane righting support support, which is traversed at approximately half its length at right angles by a hose-threaded end optionally water-carrying pipe section as an axis for the rotatable, mounted in the direction of travel hose reel.

It remains questionable whether the material used of the extremely simple hose carriage offers a permanently high resistance to mechanical stresses when a fully wound drum carries a water-filled hose.

IV metal hose trolley, dismountable

The utility model DE 18 08 672 also presents a steel tube made, in side view triangular chassis for a hose cart, the impeller, drum recording and pedestal form a tubular steel triangle construction to which - provided with a well-known lawn mowers pivoting hinge - formed by means of a rivet hinged handle with one of Hand releasable locking device is flanged, consisting of a hole with pin or a pivot pin with cotter pin or a bolt with nut, which is folded down or swung in resting or transport position and ergonomically elongating in the use position by means of the locking device to the user.

About the inclusion of the hose drum in the chassis and the hose guide and fastening no statements are made; the lightweight design of the chassis leaves questions about the usability of the hose reel when loaded by the hose-tipped drum open.

With the utility model DE 69 37 075 / German disclosure DE 19 47 859 Essentially a collapsible chassis of a hose carriage with a separate hose reel is presented, which - in the folded state - comes very close to the known laundry dryer. The made of steel tube bracket frame forms a side view of a slipped on the floor 'Y'ab, with a bottom bracket half is equipped laterally with two small rollers. In the unfolded standing state, two attached on both sides Support bars folded out of the bracket position and secured with the ends of the two support members via wing screws. Depending on a curvature at the end of the right and left side support beam to receive the hose drum and store by moving the same in recesses of the support bars at the connection points to the support members.

Although the driving and receiving frame of the hose cart can be folded down to about steel tube width in depth as specified, but the hose drum is fully preserved and accommodate. The method of the hose cart is inconvenient to hurtful and does not meet today's ergonomics in product handling.

The German disclosure DE 22 50 294 relates to a hose assembly which can be easily dismantled and put together and which has a mobile steel tube frame for forming a base and supporting a rotatable open hose reel, which is mounted in particular on a tubular, if necessary, water-carrying axle with tube couplings at its ends, and a rod-shaped axle for has the inclusion of the rotatable wheels of the hose cart. The hose trolley consists of a detachable, slightly curved at the end pipe section with handle grommet, a V-shaped pipe bifurcation with a bottom approximately right-angled bend with bearing, rod axis and impeller mount, and a screw-on U-shaped pipe bracket as a base. At the pipe bifurcation of the middle piece, the hose receiving the hose drum finds its hold by means of screw-on bearing shells. Two hollow cylindrical sections connect two side parts of spoke-spaced rings to a hose reel.

All parts of the dismountable and disassembled hose cart find their place in a flat folding carton of approximately square outer dimensions, whereby the outer diameter of the side parts of the hose reel determine the inner dimensions of the folding carton. The hose guide is done by the outside hose coupling of the pipe axis through the spokes and the sections of the drum for Aufwikkelung; a kink-free hose guide is not provided.

The utility model DE 75 33 352 is devoted to the dismantling of the hose reel of a hose cart from side spur gears and distance-holding connectors such that the connecting pieces are formed as parallel and at the same distance to the drum axis extending profile bars which are inserted at their ends via pins and corresponding pin receivers radially to the inner surfaces of the spur gears and in These connectors are held in a press fit.

The hose guide is not covered in this publication.

Like the above disclosure DE 22 50 294 also shows the utility model DE 75 41 657 an easily dismountable and assemblable hose cart comprising a mobile tubular steel frame to form a pedestal and for supporting a rotatable open hose reel, the frame below the handle-like handle at the location of the bearing for receiving the hose reel tubular axis being V-shaped downwards spreads, at the lower end of the suspension axle and the Impellers absorbs before the frame angled at approximately 90 ° in a U-shaped elbow of the pedestal.

Apart from the drum, the hose carriage frame is reduced substantially to the dimensions of the U-shaped pedestal when the above the bearing plugged into a pipe stem handle removed and the V-shaped pipe fork above the wheel axle by fixed hinges and folded.

utility Models DE 83 16 694 presents a compactly constructed, easily manufactured and manageable hose carriage of two parallel spaced, substantially triangular structurally identical side cheeks, which are connected to each other at three points by a handle arranged between them, a wheel axle and the axis of the hose reel. The flat side cheeks are in the shape of a right triangle with one of the two legs slightly inclined to the bottom and the other leg extending perpendicularly from the rear end of the first leg and extending from the front end of the leg towards the hypotenuse the triangle extending portion of the side cheeks extends only over half to two-thirds of the possible length of the hypotenuse and at its upper end the drum axis is fixed and the wheel axle is arranged at the junction of the legs perpendicular to each other between the side cheeks.

Possible hose guides and fittings are not structurally executed, just as little as the water technology, such as couplings or similar.

V Hose trolley with swiveling drum

With the patent DE 11 00 548 hose reel with reel have become known in particular for garden and land irrigation, the hose-tipped reel mounted on a wheeled chassis and with the wheels is coupled so that these move the assembled reel such as it moves the chassis in such a way that depending on Direction of travel is a winding or unwinding of the hose, wherein the length of the wound up or unwound hose exactly corresponds to the traveled distance. The chassis made of tubular steel with user-specific handle and bottom support bracket reminds in its side view very much of the wheelbarrow, the hose reel from winding drum and side windows has a possibly water-stressed tube axis and is stored with this in the leg ends of a U-shaped bracket, in turn about on the center of the stirrup leg on the chassis is pivotally hand or foot operated hinged. In the transport state, the reel is driven away from the wheels without drive; in the working state with folded bracket with equipped reel always has an impeller force-transmitting contact with the hose of the reel. In the parking position in addition, the support bracket has ground contact and the stationary impeller has a braking effect on the hose and reel.

The transverse to the direction of travel water-bearing tube axis has within the drum of the reel a radially outwardly facing hose coupling for receiving the hose to be wound up; However, neither the mounting connection nor a kink protection for the hose is to be identified. When rewinding is the Carriage to move backwards / draw, but at the same time the hose should be wound out on the behind the user drum, which is hardly possible.

By the German utility model DE 72 43 010 / Italian application IT 22 879A-72 a hose cart with a pivotable in a horizontal plane drum is published especially for garden hoses. It is a two-wheeled chassis made of substantially steel tube with a handle and an upstream support element. The hose reel is supported cantilevered on a bent existing possibly water-flow arm, which is mounted on the frame by placing it on a number of locking surfaces of different orientation, and by raising the drum and the arm of a detent surface pivotable and can be placed on another detent surface is. The drum axis points in different directions in or across or at an angle to the direction of travel. The approximately U-shaped tube arm is provided at each of its ends with a rotatable hose coupling. While the coupling at the lower end of the pipe is used to connect the water supply, the coupling is provided at the end of the pipe axis for the hose to be wound up. The connected hose is guided from outside to inside through a longitudinal slot in the side flange of the drum and wound there. Between coupling and longitudinal slot, a guide element is provided with guide surfaces outside; nevertheless, in this solution as well, due to the 3D hose guide, shear forces to be absorbed by the hose are formed from the outside to the inside.

VI Hose trolley with plastic molded parts

The utility model DE 86 15 274 and DE 86 16 352 provide hub connecting parts for connecting tubular parts - in particular for hose car - before. The center of a hose cart essentially forms the hose reel with its water technical connections, which is surrounded by two or three U-shaped metal brackets as a handle, pedestal and chassis substantially, the three ends in each one located on the two sides of the drum plastic center piece brought together on recordings, which also perpendicular to record the rotating drum hubs, and are plugged screwed with locknuts, so that a one-piece support structure for the hose reel is produced and wherein the landing gear is ground and screwed on both sides, each with a rotatable plastic wheel. Plastic hub connecting parts consisting of two matching bodies, which are arranged side by side and each have a blind hole for receiving the end of an associated part of the pipe construction and a vertical half-seat bore, which cooperate with the corresponding half-seat of the other body of the connecting part for receiving the rotating drum hub, are known.

The multi-armed hose car hub connecting part consists of an elongated single body having at its ends aligned blind holes for receiving the ends of parts to be coupled a tubular support structure and is centrally traversed by a vertical bore for receiving a rotating hub.

A similar hose cart with three U-shaped metal temples as a handle, pedestal and chassis provides the utility model DE 94 01 104 in front. The hub connection parts are designed over a large area, because they include a hand crank-driven belt drive assembly for a mechanized Schlauchaufwickeleinrichtung next to the hand crank and the hose coupling. The hose guide is arranged above the drum and consists of a tube leading by rollers slider, which is moved by a rotatable worm drive, which in turn drives the threaded rod via the hand crank with belt drive and translation.

The drive and winding system requires a precise examination, dimensioning and dimensioning of hose length per winding, taking into account the winding levels and the hose diameter to obtain a clean winding - as shown. The hose must be guided from the inner hose coupling kink free to the winding.

A hose trolley with electric rewinder represents utility model DE 201 08 927 in front; Also in this solution, the geometric relationships of hose diameter, winding length and winding position must be taken into account.

Through the Canadian release CA 2 505 175 / American registration US Pat. No. 7,017,603 . US 530 875 S is a made of metal and plastic parts, 4-wheel hose known, which also has the characteristics of a workshop car. For the storage of the car, the hand crank can be folded.

VII plastic hose trolley, can be dismantled

utility Models DE 92 10 081 discloses a hose cart consisting of substantially three U-shaped metal brackets as a handle, pedestal and chassis, each merged on one side, the three ends in a plastic hub in recordings and are screwed pluggable with locknuts. The landing gear bracket is screwed on both sides with a plastic wheel. The hose reel consists of left- and right-side flange, in which the hub halves are latched by means of snap-in engagement means, and likewise the hub halves are latched together. While a rotary bearing of the hose reel is equipped with a hand crank, the opposite rotary bearing is provided with an inside and outside hose coupling. Both hub halves can each recognize a recess through which the hose can be plugged into the internal coupling and tightened and brought to the outside to the drum for winding. All items can be packaged in a flat, nearly square carton, the length / width of which is determined essentially by the diameter of the drum flanges and the tensioned surface of the U-bolts.

The accessibility of the internal hose connection can not be determined; a defined, kink-free hose guide is not provided.

utility Models DE 297 23 788 presents a hose reel for a hose trolley or carrier - for receiving in particular a garden hose - consisting of two identical, mirror image joinable reel halves with at the end support flanges projecting substantially parallel to the axis, in an assembled arrangement to a winding core complementary web approaches that can be attached to each other in a radial plane Have end faces, in the region locking means for the cohesion of the reel halves are arranged.

Despite the use of an angled hose rotary coupling kinking the hose guide must not be given.

Newer all-plastic equipment - like the Canadian application CA 2 452 461 / American patent US 2004 188 558 or the German applications DE 10 2009 000 764 and DE 10 2009 000 765 - Move the manually operated crank increasingly in the grip height of the device, so that the take-up device can be operated by the user in the state. A coupling ensures that the crank mechanism runs counter to the winding without effect empty, so that the laying out of the hose can be done while driving.

If the hose cart does not have a mechanized rewinder, the user needs a third hand for rewinding; The carriage must be moved, by means of the crank, the hose should be wound up while standing and the guided winding on the drum must be done in a bent position.

The American design patent US Pat. No. 5,033,837 p shows a 3-bar - handle bar, base and chassis - with hand-driven hose reel in all-plastic execution.

A similar design is made by the Canadian patent CA 2 429 306 / American registration US 2004 084 084 known; The handle and the pedestal form visually a frame from which the chassis is derived vertically downwards.

A collapsible and zusammensteckbaren hose carriage made of plastic material is also in the US patent US 5,425,391 presented.

The circular disk of the center console forms a plane of symmetry for the axial extent of the hose winding device.

In a further advantageous embodiment of the invention in arrangement and execution forms a water hose coupling the two hose reels watering a special feature. The hose connector connects the two hose connections of the hose reels in terms of water technology and is designed so that the hose connection of one hose reel points in the direction of travel and the other in the opposite direction, so that - in relation to the media transport - the hose reel with unwound hoses forms a coupling, transmission line. and extension station represents. Since the hose reels can be operated manually independently of one another, two hoses, which are each designed to be remote from the hose trolley and opposite in direction, can be wound up ergonomically, both from a standing position and by a method. The application of wound hoses is done in reverse order user friendly.

At the execution of the hose connector high technical requirements are made; on the one hand, it produces a water-technical connection, which of course must be tight. Furthermore, there is the requirement - since the two hose reels rotate independently - that the position must be centered and the water pipe coupling must be rotatable. Furthermore, it follows from the arrangement with the center console, that act at this point, the bearing forces of both winding devices and they must be absorbed by the recordings at the bearing. A particularly advantageous embodiment of the center console with three hollow cylindrical receptacles meets the above requirements set low.

Another embodiment of the invention is given by the fact that the hose connections of the hose connector of the hose reels - easily accessible to the user - in a recess of the winding drum of the hose reel and this recess for hose guide only after about 3/4 turn or 270 ° rotation of the Winding drum runs out to the drum surface. The Arrangement of the hose connection of the hose connector forms a tangent to the winding drum circumference, is flush with the drum surface and is guided by a radial plane within the winding drum recess. This means a gentle, absolutely kink-free guidance and winding for the hose. The hose guide is shown here by way of example in the middle; but it can also be moved to the inner or outer edge of the drum - without causing disadvantages; the number of plastic injection molds is maintained by the symmetrical arrangement of the winding body parts.

According to a further embodiment of the invention, the handle bar is provided at the location of handling the hose cart with a handle. In addition, a suspension device for hose ends, hose coupling parts and / or various syringes and sprinklers is provided ergonomically favorable in the vicinity of the handle.

A preferred embodiment of the invention provides for the production of hose reels and wheels as possibly multicomponent injection-molded, UV-resistant plastic parts that are transported optimized packaging according to their outer dimensions and can be built by the future user in-house performance with little help from tool to hose cart.

Locks for hose reels and wheels can be - as by permanent magnet couplings or mechanical solutions, as in connection with the hand crank drive - complement.

Fig. 3 shows the hose winding device 5 of the hose cart 1 in section and in half as an exploded view. Two bobbin halves 512, 513 each form a winding drum 514 which is closed on the one hand by the fixed drum rim 511 and on the other hand by the center console 55 , which is also stabilized by supports. At the mid-axis separation point of drum rim 511 and winding body 512 , a rotary bearing is formed by the outer part rings 519, 520 by means of the inner ring 515 , which is closed here by a sealing cap 516 . Not shown is the axle guidance and connection of the crank mechanism of the hand crank 525. The radially expanded circular disk 553 of the fixed center console 55 has a hollow cylindrical outer shell 551 as a sealing closure to the winding body half 513. Two further receiving rings 555, 556 form a stabilizing sliding pivot bearing for the outer ring 520 of the winding body half 513 . The threaded union 559 with external thread - screwed to the internal thread of the receiving ring 556 - positioned both the winding drum 514 as well as the yet to be shown connecting piece 573 of the rotatable hose connector 57th The wall plate of the center console forms a mirror-symmetrical plane of symmetry for axial expansion of the hose winding device 5. The sections 517, 518 marked as radial plane take the hose connection 571 of the hose connector in one piece and tangentially to the winding drum circumference. The hollow cylindrical connection angle 572 connects the hose fitting with the tubular connecting piece uniform.

Fig. 4 finally shows the hose connector 57 in section and in half as an exploded view. At the execution of the hose connector high technical requirements are made; On the one hand, he produces a sealed water-technical connection. Furthermore, there is the requirement - since the two hose reels 51, 53 rotate independently of each other - that the position is centered and the water pipe coupling 571, 572, 573 must be made rotatable. Furthermore, it follows from the arrangement with the center console 55 that act at this point, the bearing forces of both winding drums 514 and these must be taken from the receptacles 555, 556 at the bearing point. A particularly advantageous embodiment of the center console with three hollow cylindrical receptacles 555, 556, 557 meets the above set up requirements low. While the threaded union 559 has the mechanical guidance of the rotatable connecting piece 573 on the center console, the sealing ring 558 ensures the water-tight connection.

Fig. 5 shows the center console 55 with hose reel 51 of the hose winding device 5 as a 3D exploded view. It should be added that the center console is formed as a spoked wheel 554 , which terminates at the outer periphery with an outer shell 551 and wherein two spokes are hollow cylindrical and about the tube receptacles 552, the support tubes 32, 42 receive a tight fit. The various receiving cylinder 555, 556, 557 of the center console take the outer part of ring 520 of the bobbin 513 rotatably, the connecting piece 573 via the sealing ring 558 also rotatable and the threaded cover 559 stuck on. The radially extending plane of the winding drum depression formed by the partial surfaces 517, 518 positions the hose connection 571 tangentially to the winding drum circumference. The absolutely kink-free hose guide is achieved by the approximately 270 ° encircling, towards the hose connection opposite end towards decreasing recess 521 in the winding drum surface. In this illustration, the hose guide is laid on one side to the inner edge of the winding body 513 ; the winding drum parts 512, 513 are asymmetrical.
