Description

The invention relates to a load handling device according to the preamble of patent claim 1.

A load handling device of the type mentioned is for example from the patent document DE 10 2015 012 678 B4 known. This load transport device consists of a heavy load to be transported (not shown separately in the figures) and frame parts for carrying the load, with a wheel on both sides of the load being provided on the frame parts for tilting and for rolling transport of the load. In this solution, the wheels on both sides, and this can also be the case in the solution according to the invention that is yet to be explained, are designed as so-called star wheels, so that transport over stairs works particularly easily. Here and in the following, "heavyweight" is understood to mean loads that an average strong person cannot or does not want to carry or transport by hand, ie typically such loads that weigh more than 20 kg.

The object of the invention is to improve a load handling device of the type mentioned at the outset. In particular, a load transport device that is itself particularly easy to transport is to be created.

This object is achieved with a load handling device of the type mentioned by the features listed in the characterizing part of patent claim 1.

According to the invention it is thus provided that the load itself is used as a load-bearing connecting element (but not as a usual component of such a load-handling device [e.g. a metal strut]) between a wheeled frame part arranged on one side of the load and one on the opposite side of the Last arranged, also provided with wheel frame part is formed.

In other words, the solution according to the invention is characterized in that the load itself forms part of the load transport device, which means that it is only functional together with the load or can be used like a sack truck. In front of the connection to the load, there are preferably only two side parts, each consisting of a frame part and a wheel, which can easily be transported separately after removal from the load.

In all of this, it is particularly preferred that a heater, for example a heating boiler, in particular for gaseous or liquid fuels, forms the said load, i. H. a heating installer keeps the two said side parts in case he has to transport such a heating device. To do this, he fastens the side parts to the load or the heater, which will be explained in more detail below, transports them to the desired location and removes the side parts there again, which by themselves do not yet form a load transport device. Since the side parts are relatively small and light compared to a normal sack truck, they can be easily accommodated in the delivery vehicle, for example.

Other advantageous developments of the load transport device according to the invention result from the dependent patent claims.

For the sake of completeness, reference is also made to load handling devices as can be found in Wikipedia: See https://de.wikipedia.org/w/index.php? title=Hand Truck&oldid=209031104.

The load transport device according to the invention, including its advantageous developments according to the dependent patent claims, is explained in more detail below with reference to the graphic representation of a preferred exemplary embodiment.

• 3 perspektivisch ein Rahmenteil ohne Last und ohne Rad;
• 4 perspektivisch ein Rahmenteil und ein zur Achse fluchtendes, aber nicht montiertes Rad;
• 5 in Seitenansicht die erfindungsgemäße Lastbeförderungsvorrichtung mit zwei Rädern in Gebrauch; und
• 6 perspektivisch die erfindungsgemäße Lastbeförderungsvorrichtung mit zwei Sternrädern in Gebrauch.

It shows

• 1 in perspective the not yet fully assembled load handling device according to the invention;
• 2 in perspective the attachment of the frame part to the load in the area of the wheel (not shown);
• 3 in perspective a frame part without a load and without a wheel;
• 4 perspective of a frame part and a wheel aligned with the axle but not mounted;
• 5 in side view the load handling device according to the invention with two wheels in use; and
• 6 perspective the load handling device according to the invention with two star wheels in use.

The load handling device shown in the figures consists initially in a known manner of a to-be-transported, heavy load 1 and frame parts 2 for carrying the load 1, with both sides of the load 1 to the yard ment parts 2 each have a wheel 3 for tilting and for rolling transport of the load 1 is provided.

What is essential for the load transport device according to the invention is that the load 1 itself acts as a load-bearing connecting element between a frame part 2, which is arranged on one side of the load 1 and is provided with a wheel 3, and a frame part 2, which is arranged on the opposite side of the load 1 and is also provided with a wheel 3 is trained.

Furthermore, it is preferred that an opening 1 . 1 is provided on the load 1 for receiving a pin arranged on the frame part 2 .

In addition, it is preferable for the wheel 3 to be fastened to the frame part 2 to be arranged on an axis 4 which runs horizontally when the load transport device is used as intended. The axle 4 is preferably designed to protrude not only in the direction of the wheel from the frame part 2, but also in the direction of the load 1, see FIG 2 . It is also preferred that the axis 4 partially forms the (aforementioned) pin.

Furthermore, it is preferred that the frame part 2 is designed as a straight carrier, with a handle 2.1 being arranged at one end of the carrier and the wheel 3 being arranged at the other end of the carrier, see FIG 1 . In addition, it is preferable for the load 1 and the frame parts 2 to be designed so that they can be connected to one another at a number of connection points 5, see FIG 1 and 3 . It is preferred here that a first connecting device 6 designed as a screw connection is provided at a connecting point 5 . This enables a particularly stable attachment of the load 1 to the frame parts 2. It is also preferred that the screw connection is formed from a fixing screw 6.1, a through-opening 6.2 on the frame part 2 and a threaded hole 6.3 on the load 1, see 2 , Wherein the fixing screw 6.1 is preferably designed without tools and can be operated by hand. In addition, it is preferred that several connection points 5, in particular through-openings 6.2, are distributed on the frame part 2 for loads 1 of different sizes. In addition, it is preferable for each frame part 2 to have at least one screw connection both on the wheel side and on the handle side.

Furthermore, it is preferred that a second connection device 7 designed as a plug connection is provided at another connection point 5 . Such a plug-in connection enables a particularly simple and quick connection of the load 1 to the frame parts 2. The plug-in connection preferably includes the axle 4 of the wheel 3, see FIG 2 and 4 . It is also preferred that the axes 4 of the two frame parts 2 are arranged lying on a line when the load transport device is used as intended.

In addition, it is preferred that the load 1 is optionally cuboid in shape and/or that the load 1 is in the form of a heating device.

Finally, it is still preferred that both wheels 3 are designed as star wheels, see FIG 6 . This has the advantage that the load transport device according to the invention enables a particularly comfortable transport of the load 1 over stairs.

• Die quaderförmige Last 1 weist in diesem Beispiel an ihrem hinteren unteren Rand die Öffnungen 1.1 auf. Die Last 1 wird zunächst von einem Transporteur über ihren vorderen unteren Rand leicht nach vorne gekippt. Als nächstes werden die zwei Rahmenteile 2 jeweils mit ihrer dem Rad 3 abgewandten Seite der Achse 4 in die zugehörige Öffnung 1.1 der Last 1 gesteckt. Hiernach werden die Rahmenteile 2 in den Öffnungen 1.1 um ihre Achsen 4 so gedreht, dass jeweils eine der Durchgangsöffnungen 6.2 mit einer Gewindebohrung 6.3 an der Last 1 fluchtet. Danach wird jeweils eine Fixierschraube durch die Durchgangsöffnungen 6.2 in die entsprechende Gewindebohrung 6.3 gesteckt und per Hand festgezogen.

The assembly and disassembly of the load handling device according to a preferred embodiment of the invention works as follows:

• In this example, the cuboid load 1 has the openings 1.1 on its rear lower edge. The load 1 is first tilted slightly forward by a transporter over its front lower edge. Next, the two frame parts 2 are each inserted with their side of the axle 4 facing away from the wheel 3 into the associated opening 1.1 of the load 1. The frame parts 2 are then rotated about their axes 4 in the openings 1.1 in such a way that one of the through-openings 6.2 is aligned with a threaded hole 6.3 on the load 1. A fixing screw is then inserted through the through-openings 6.2 into the corresponding threaded hole 6.3 and tightened by hand.

In this state, the carrier can now grab the handles 2.1 of the load handling device, tilt the device around the axles 4 backwards and start driving with it.

In principle, when the carrier has arrived at the destination, he can perform the above-described operation backwards in order to disassemble the load conveyor and put the load 1 down. Because of their relatively low weight, he can then easily pick up the frame parts 2 and, because of their comparatively small volume, stow them away in a space-saving manner.

As can clearly be seen from this, the load handling device according to the invention is therefore designed to be very space-saving and light, and yet easy to set up and use.
