Description

The invention relates to a device for lifting and transporting components, in particular windows and / or doors. A method for installing a component, in particular windows and / or doors, with a corresponding device is also disclosed.

The object of the invention is defined in the appended claims.

As in almost all areas of economic life, there is a constant need for improved processes and more efficient ways of working in the area of construction in order to be able to implement complex construction projects within strict time and cost requirements. A central aspect here is the question of how many workers have to be parked on site to carry out an operation or how quickly and precisely the workers can perform an operation assigned to them. There is therefore a continuing need for improved devices with which the processes and work steps occurring on a construction site can be carried out particularly efficiently.

Appropriate devices are not only subject to high requirements with regard to operational safety, but it is also expected that these devices are particularly robust in everyday construction site work and are not prone to errors.

A typical recurring work step on many construction sites is the installation of essentially plate-shaped elements, in particular doors and windows, in the installation sites provided. The mostly heavy components have to be picked up by the workers in a delivery or storage area and transported to the installation site.

Over the years, various transport devices have been developed for essentially plate-shaped components, such as those in the US 5318316 be disclosed. Appropriate devices facilitate the otherwise extremely energy-consuming transport of the heavy components over the construction site, so that the efficiency of the workers employed can be increased.

Based on these transport devices, more sophisticated devices have been developed that not only enable the components to be transported easily, but can also assist the worker in assembling the component by lifting the component to a necessary mounting height, so that the workers do not use their own strength at the installation site must be used to raise the component to the intended mounting height before installation. An exemplary device, which is also available in a slightly modified form on the market, is in the EP 2 939 903 disclosed.

The in the EP 2 939 903 B1 The device disclosed consists of two essentially vertically arranged side elements, each of which is supported by a wheel and is movably connected to a horizontally arranged flexible floor element, a holding element and a lifting system, the flexible base yielding and the laterally arranged vertical elements when the structural element is inserted into the holding element Side elements securely enclose the component placed inside. As an advantage of this device, it is stated in particular that a corresponding component can be transported particularly safely in the device. Despite this advantage, the in EP 2 939 903 However, the device described is sometimes found to be disadvantageous because it requires two additional supports for lateral stabilization in assembly operation, by means of which the overall weight of the device increases and the workload in the assembly step increases. In addition, due to its flexible base element and the movably arranged side elements, the corresponding device is perceived as too fragile for some everyday use on construction sites. In addition, it is sometimes felt to be disadvantageous that a component to be used can often only be inserted into the device from the front or the rear, and thus must be guided with its entire longitudinal direction through the device, since the vertically arranged side elements prevent the lateral insertion of the Prevent component. As a result, the corresponding device may be difficult to load, particularly by a single worker. In addition, it is sometimes felt to be disadvantageous that due to the particularly secure edging of the component by the two vertical side elements, the adjustability of the component during installation, that is to say the degrees of freedom of the component arranged in the device, is disadvantageous since it is more difficult for the component in this arrangement to tilt laterally relative to the device.

The primary object of the invention was to provide a device for lifting and transporting components which eliminates or at least reduces the disadvantages of the prior art described above.

In particular, it was an object of the present invention to provide a device with which components can be securely lifted even in very high-level mounting positions, so that high-level windows can also be mounted.

In addition, it was an object of the present invention to provide a device which can also be loaded easily and in a time-efficient manner by a single worker.

In addition, the device should be made particularly robust and have a high degree of mobility even on difficult ground. The device should not only be as light as possible, but should also occupy the smallest possible storage space.

Despite being as robust and simple as possible, the device to be specified should enable safe storage of the components to be transported and / or assembled, ideally also without separate securing elements, e.g. Clamps, clips or straps.

It was the requirement that loading should also be possible if the corresponding component could only be lifted slightly by the workers.

The task is of particular importance that the device to be specified should be particularly efficiently aligned at the installation site and that the component should have many degrees of swivel and freedom of movement so that it can be optimally adapted to the installation position.

An important object of the present invention was to provide a device which can be operated particularly safely, and in the light of the stricter requirements on numerous construction sites, a particular challenge was to specify a device which can be operated and operated efficiently by two workers during transport can, but at the same time enables trouble-free mounting of components in the area near the wall.

In particular, the device to be specified, in particular to increase safety, should have a high degree of lateral stability, especially during the assembly step, even without additional supports, but preferably does not restrict the adjustability of the window in lateral directions.

In addition, the device to be specified should have a high degree of flexibility with regard to the lifting device to be used.

The above-mentioned objects are achieved by devices for lifting and transporting components as defined in the claims. Preferred configurations according to the invention result from the subclaims and the following explanations.

Such features of the device according to the invention for lifting and transporting components, which are referred to below as preferred, are combined in particularly preferred embodiments with other features designated as preferred. Combinations of two or more of the devices for lifting and transporting components and corresponding methods, which are referred to as particularly preferred below, are therefore very particularly preferred.

• - ein Bodenelement,
• - zwei an den Seiten des Bodenelements koaxial zueinander angeordnete Räder, durch die die Bewegungsrichtung der Vorrichtung definiert wird,
• - ein Trägerelement, welches mit dem Bodenelement verbunden ist,
• - eine Aufnahmevorrichtung mit einem länglichen Aufnahmebereich zur Aufnahme eines Bauelements, wobei die Aufnahmevorrichtung beweglich mit dem Trägerelement verbunden ist, um eine vertikale Bewegung der Aufnahmevorrichtung relativ zum Trägerelement zu ermöglichen,
• - eine Hebevorrichtung, die dazu eingerichtet ist, die Aufnahmevorrichtung relativ zum Trägerelement in vertikale Richtung zu bewegen,

wobei die Aufnahmevorrichtung so angeordnet ist, dass der längliche Aufnahmebereich parallel zur Bewegungsrichtung verläuft, und wobei das Bodenelement und das Trägerelement einen Winkel im Bereich von 45° bis 85° einschließen.The invention relates to a device for lifting and transporting components, in particular windows and / or doors, comprising

• - a floor element,
• two wheels arranged coaxially to one another on the sides of the base element and defining the direction of movement of the device,
• a carrier element which is connected to the base element,
• a receiving device with an elongated receiving area for receiving a component, the receiving device being movably connected to the carrier element in order to enable vertical movement of the receiving device relative to the carrier element,
• a lifting device which is set up to move the receiving device in the vertical direction relative to the carrier element,

wherein the receiving device is arranged such that the elongated receiving area runs parallel to the direction of movement, and wherein the base element and the carrier element form an angle in the range from 45 ° to 85 °.

The device according to the invention is suitable for lifting and transporting components, in particular windows and / or doors, the suitability for windows being particularly preferred since these have to be raised regularly to large installation heights, so that the advantage of the device according to the invention is particularly evident .

The device according to the invention comprises a base element and two wheels arranged coaxially to one another on the sides of the base element, by means of which the direction of movement of the device is defined. The floor element in the sense of the present invention is thus the deepest structure on which the two wheels arranged coaxially to one another are arranged at least indirectly are. The two wheels arranged coaxially to one another can be connected by an axle or fastened in alignment to the floor element, as a result of which there is a corresponding imaginary axle between the wheels. The two wheels define the direction of movement of the device, which is perpendicular to the connecting axis of the two wheels, similar to a single-axle trailer.

The device comprises a carrier element, which is connected to the base element, and on this carrier element a receiving device for receiving a component, which is connected to the carrier element in such a way that a vertical movement of the receiving device is made possible relative to the carrier element. This relative movement of the receiving device relative to the carrier element is realized according to the invention by a lifting device. Devices according to the invention are preferred, the device being set up to raise the receiving device relative to the base element by at least 300 mm, preferably at least 600 mm, particularly preferably at least 900 mm.

In the sense of the present invention, the term vertical movement in accordance with the technical understanding means that the movement vector of the movement has a vertical component which is at least as large as the largest component in the horizontal.

The device according to the invention has an elongated receiving area which is provided for receiving a component. This elongated receiving area can be formed in one piece or in several pieces and is preferably formed by an elongated groove, the width of which is suitable for placing at least one component therein. The elongated receiving area of the receiving device is set up so that the essentially plate-shaped component can be arranged upright in the elongated receiving area, i.e. that the plane formed by the plate-shaped component does not run essentially parallel to the floor.

According to the invention, the receiving device is arranged such that the elongated receiving area runs parallel to the direction of movement of the device defined by the wheels. This is essential, since it makes the installation of windows much easier. With this arrangement, it is namely possible to move the device according to the invention in the direction of the assembly position and in doing so to guide the fastening elements provided on the component first into the installation site, which enables the highest possible accuracy of fit and precise adjustment.

The device according to the invention is thus moved up to an installation location, for example a recess in a wall in which a window is to be installed. In this arrangement, the component can be raised with the device according to the invention and brought to the assembly height. The fastening elements of the component point to the corresponding counterparts in the wall recess, so that the component can be fixed particularly easily in the frame. This is a clear advantage over all devices in which the component is arranged essentially perpendicular to the direction of movement.

In the context of the present invention, the expression parallel means that two corresponding elements are essentially parallel. In accordance with the expert understanding, this means that small deviations from the perfect parallel design do not mean that the person skilled in the art would not call an arrangement parallel. For the purposes of the present invention, two straight lines or areas are also assumed to be parallel to one another if they enclose an angle of 5 ° or less.

In addition, it is essential for the device according to the invention that the base element and the carrier element enclose an angle in the range from 45 to 85 °. This means that the carrier element, along which the lifting device can be moved up and down, is inclined relative to the mostly horizontal floor element. This makes it possible for a component inserted into the receiving device to be held in the receiving device by its own weight, so that it is stabilized by its own weight even when it is raised to the mounting height without a second fixing side element, as in the prior art must be provided. This additional freedom makes it possible to tilt the component raised to the assembly height particularly easily with respect to the carrier element and the receiving device in such a way that a perfect engagement between the fastening elements on the component and the fastening points provided on the frame is achieved. Small angles are particularly suitable for the particularly safe transport of valuable components, especially in low-obstacle outdoor areas, especially when only small installation heights are to be expected. For construction sites with narrow corridors and doors as well as with many high-altitude installation sites, however, the larger angles are preferred because a more compact and maneuverable device is obtained, which can lift the components more efficiently even at great heights.

A device according to the invention is preferred, the base element being horizontal is arranged, and / or wherein the plane spanned by the base element and / or the surface of the base element runs parallel to the connecting axis between the coaxially arranged wheels.

As explained above, high demands are placed on the robustness of corresponding devices. In this respect, the inventors have found that it is particularly advantageous to design the floor element, in contrast to the prior art, as a rigid floor element, which gives the basic device the necessary stability. It has proven to be particularly advantageous to provide sufficient ground clearance so that the device according to the invention can be moved easily and reliably even on uneven ground without the support frame getting caught on obstacles.

An apparatus according to the invention is therefore very particularly preferred, the base element being a rigid base element, preferably a metallic support frame or a metallic support plate, and / or the apparatus having a ground clearance of 50 mm or more, preferably 100 mm or more.

A device according to the invention is preferred, the wheels being spaced apart from one another along the connecting axis, preferably at least 50 cm, particularly preferably at least 70 cm, and / or the wheels being designed as pneumatic tires or as solid rubber tires or as polyurethane tires.

In the construction of the device according to the invention, it has proven to be advantageous that the lateral stability of the device according to the invention can be ensured in that the two wheels arranged coaxially on the base element are sufficiently spaced from one another.

It has proven to be particularly advantageous that the device comprises exactly two wheels. This creates only one axis around which the device can be pivoted, namely forwards and backwards. This not only increases maneuverability on the heavy ground of a construction site, but also enables better adjustability when assembling the component, since the device arranged together can also be used to rotate the component arranged around the connecting axis of the wheels. In order to improve the usability by a single worker, a tilt protection is preferably also provided in this case, with which the device can be fixed in the selected inclination.

A device according to the invention is therefore very preferred, the device comprising exactly two wheels and a device according to the invention, the device being designed such that the device can be pivoted about the connecting axis between the coaxially arranged wheels, the device preferably comprising at least one anti-tip device , with which a pivoting of the device around the connecting axis between the coaxially arranged wheels can be prevented or at least restricted, preferably two preferably extendable anti-tipper elements being arranged on the side of the carrier element facing away from the receiving device.

Alternatively, a third wheel can also be provided, which is not aligned coaxially with the two other wheels, but rather functions as a support and steering wheel, as is known, for example, from vehicle trailers. A corresponding wheel will regularly be made smaller than the other two wheels. In a particularly preferred embodiment, the anti-tip is also at least partially formed by a third wheel.

A device according to the invention is preferred, wherein the support element is designed as a support frame, preferably as a metallic support frame, and / or wherein the support frame comprises at least one guide rail, preferably at least two guide rails, which is set up so that the receiving device is arranged in it via connecting elements can be movably connected to the support element, and / or wherein the support element is welded or riveted, preferably welded, to the base element, and / or wherein the support element on the side opposite the base element is an eyelet for attaching a rope or a Hooks includes.

In the construction of the device according to the invention, it has proven to be advantageous, in particular with regard to the robustness, if the carrier element is designed as a carrier frame. The attachment of a guide rail has proven to be a comparatively simple, but efficient way of movably connecting the receiving device to the carrier element and thereby ensuring sufficient stability which, for example, would not be possible to the same extent with belts as the receiving device. The design of the support element as a support frame also makes it possible to provide an eyelet for fastening a rope or a hook at the upper end of the support element, with which the device according to the invention can be implemented particularly easily on the construction site and / or can be transported to higher floors by this For example, is picked up by a crane, which significantly reduces the work involved in transporting the device can be. As a positive side effect, efficient nighttime theft protection can also be made possible by pulling up the device on a crane.

Even if it were possible in principle to design the receiving device only through the elongated receiving area, it has proven to be particularly advantageous in practice to also design the receiving device as a frame construction which is connected to the carrier element. In this case, the component to be used can be leaned against the frame construction and does not experience any frictional contact with the carrier element when the component is lifted, so that the component is protected. For this purpose, it is particularly advantageous if the frame construction is additionally arranged with plastic protective strips, which proves to be particularly useful when particularly high-quality components are to be transported, in which scratching should be avoided at all costs.

The arrangement of the receiving device above the height level of the base element has proven to be advantageous in order to avoid damage to the component during transport, which could occur in practice if the component is transported too close to the ground.

Even if it were possible in principle to design the elongated receiving area as a bare sheet metal, it has proven to be particularly advantageous in practice to provide a side limitation, so that the components used in the receiving device are held not only by their own weight, but also by the Side limit can be fixed. Especially when the windows have been raised to the installation height, such a design has also proven to be particularly effective in terms of occupational safety.

It has proven to be particularly helpful for the transport of large components, in particular, to provide further projections on the frame structure, which are set up to fasten the components arranged in the receiving device to them with fastening means. This can be, for example, lashing straps or ropes, although it is again advisable to use them with more valuable components. In order to reduce the space requirement of the device, for example during transport to the construction site, and to minimize the risk of damage to the construction site by tapping the corresponding projections, it has proven to be particularly advantageous to design the hook elements to be reversible and non-destructively adjustable in length, these hook elements can be designed, for example, in the form of telescopic elements.

In the light of these explanations, a device according to the invention is preferred, the receiving device comprising a frame construction, the receiving device in the initial state preferably being arranged above the height level of the base element, the receiving device preferably being connected to the carrier element via the frame construction, with the elongated receiving area being attached to it facing side of the frame structure is preferably arranged at least one protective strip made of plastic, the elongated receiving area preferably having a side boundary on the side facing away from the frame structure, the bottom of the elongated receiving area optionally being coated with a non-slip coating, and wherein the frame structure on the elongated one Receiving area opposite half preferably has at least one protrusion, particularly preferably at least two protrusions, which are set up so that an in the component arranged in the receiving device can be fastened to it with fastening means, the projection or the projections preferably being designed as reversible and non-destructively adjustable hook elements.

As explained above, the device according to the invention is advantageously set up so that a component which is only slightly raised during loading, for example because of the high weight or a limited ceiling height, can be introduced frontally into the receiving device and placed in the elongated receiving area. As explained above, this is not possible with some devices from the prior art and the quick loading, even by just one worker, is a great advantage of the device according to the invention. Even if the device should be operated by two workers during transport and assembly for safety reasons, it is advantageous that another worker can take over the loading of the device alone, and thus, for example, be able to look after several deployment teams with appropriate devices that follow the quick loading process to the next assembly point.

A device according to the invention is therefore preferred, the device being set up in such a way that a component which is only lifted 400 mm or less, preferably 300 mm or less, can be introduced frontally into the receiving device, so that the direction of insertion is parallel to the device Connection axis between the coaxially arranged wheels runs.

The device according to the invention is advantageously not limited with regard to the type of lifting device used. The robust construction makes it possible to install numerous different lifting devices, whereby in practice the winch and a corresponding manual lifting device have proven to be particularly powerful. This is due in particular to the high level of robustness, but also to the simple operation of this lifting mechanism, which can also be easily repaired on site at the construction site if necessary.

A device according to the invention is therefore preferred, the lifting device being a manually, pneumatically, hydraulically or electrically operated lifting device, preferably a manually operated lifting device, particularly preferably a cable winch, the cable of the cable winch preferably being guided to the receiving device via a deflection roller attached to the carrier element.

In our own experiments with the device according to the invention, it has been shown that it can be expedient to allow the receiving device to be lowered, in particular damped, and to provide a separate mechanism for this purpose, which can be designed, for example, as a hand or foot release. Depending on the position of the lifting device, which is often provided centrally in the middle of the device for reasons of even lifting, it may be difficult when the device is being maneuvered into the installation position to snap the component raised to the mounting height into the fastening positions provided for this purpose , if the holding device cannot be lowered at least slightly without touching the lifting device. This problem is solved in that the trigger is spaced from the lifting device, preferably arranged on a handle.

A device according to the invention is thus preferred, the lifting device being equipped with a trigger for lowering, preferably for damped and / or piece-wise lowering, of the receiving device, the trigger preferably being designed as a hand or foot trigger and the trigger preferably being spaced apart from the lifting device , preferably on a handle.

Even if, as explained above, it is possible in principle to provide the device according to the invention without restriction with a smaller angle between the support element and the base element, it is very particularly preferred to use large angles which are just sufficient for a device arranged in the receiving device Component is fixed in this arrangement by its own weight.

A device according to the invention is therefore preferred, the base element and the carrier element enclosing an angle in the range from 60 ° to 85 °, preferably 70 ° to 85 °, particularly preferably 80 ° to 85 °, and / or the receiving device being set up for this purpose, to be moved by the lifting device relative to the carrier element along a lifting direction, the lifting direction with the connecting axis between the coaxially arranged wheels making an angle in the range from 45 ° to 85 °, preferably 60 ° to 85 °, particularly preferably 70 ° to 85 °, very particularly preferably 80 ° to 85 °.

In practice, it has proven particularly useful to arrange the carrier element between the two wheels so that this leads to the most stable device, in particular if the carrier element is also supported by supporting elements.

A device according to the invention is therefore preferred, wherein the base element and the carrier element are additionally connected to one another via one or more support elements, and / or the carrier element is arranged between the two wheels.

It was an important object of the present invention to provide a device which can be operated efficiently by two people. Especially in the confined space of the construction company, it is usually necessary for one person to pull and one person to push, so that both workers can also secure the component to be transported with their hands if necessary. It has therefore proven to be particularly advantageous that the device comprises at least two handles that are spaced apart from one another along the direction of movement and that are arranged on different sides of the carrier element relative to the direction of movement. With corresponding arrangements, however, a fundamental problem has arisen with the intended function of the devices according to the invention. To mount the component arranged in the device, it is in fact regularly necessary to move the device substantially perpendicularly to a wall in order to be able to drive as close as possible to the installation site for the component. If handles are arranged on both sides of the carrier element, however, these stand in the way of a frontal approach of the device to a wall and can therefore in some situations result in the device according to the invention not being able to be used in a sensible manner. To solve this problem, the inventors have identified that the corresponding handles, or at least one of the Handles that are reversible and non-destructively extendable. In this case, the device according to the invention can be moved across the construction site by two workers, for example. When the assembly point is reached, one of the handles is drawn in and the device is moved up to the wall, where it can be used without hindrance from the handles.

Correspondingly, a device according to the invention is preferred, the device comprising at least two handles spaced apart along the direction of movement, the handles preferably being at least 1000 mm, particularly preferably at least 1200 mm, very particularly preferably at least 1400 mm, the handles preferably being on different Sides of the support element are arranged, wherein the handles are particularly preferably designed to be reversible and non-destructive, preferably telescopic, stepless or step-like, extendable and fixable in the extended state, the device preferably being provided with a control unit by means of which the handles on at least one side of the Device can be retracted and extended.

A similar problem can arise for devices according to the invention if an obstacle is arranged in front of the intended assembly point, by means of which a tight approach of the device according to the invention to the installation site is prevented. This can be, for example, a radiator that was installed in front of the window before the windows were installed. To solve this problem, the inventors propose to provide a displacement mechanism by means of which the receiving device can be displaced not only vertically but also relative to the carrier element along the direction of movement and thus towards the assembly point. A corresponding design is, however, particularly suitable for special applications and is not necessary for the vast majority of cases, in particular since the durability and the price of corresponding devices can be adversely affected thereby.

A device according to the invention is therefore preferred for special fields of application, the device comprising a displacement mechanism, preferably an electrical actuator, with which the receiving device can be displaced relative to the carrier element along the direction of movement.

The invention and preferred embodiments of the invention are explained and described in more detail below with reference to the accompanying figures. The same reference numerals in different figures denote the same components.

• 1 Eine erfindungsgemäße Vorrichtung in einer bevorzugten Ausführungsform in einer perspektivischen Ansicht; und
• 2 Eine erfindungsgemäße Vorrichtung in einer bevorzugten Ausführungsform in einer Frontansicht.

The figures show:

• 1 A device according to the invention in a preferred embodiment in a perspective view; and
• 2nd A device according to the invention in a preferred embodiment in a front view.

The 1 and 2nd show a device according to the invention in a particularly preferred embodiment, each in a perspective and a front view. The device shown 10th is intended for lifting and transporting components and especially designed for lifting and transporting windows.

In the 1 and 2nd is clearly the cradle 18th to recognize the elongated recording area 20 comprises, which is provided for receiving a component. The cradle 18th is movable with the support element 16 connected. This allows the cradle 18th relative to the support element 16 be moved vertically, ie up and down. This is done by the lifting device 22 , which is thus set up, the receiving device 18th to move accordingly.

In the 1 and 2nd it can be clearly seen that the receiving device 18th is arranged so that the elongated receiving area 20 parallel to the direction of movement C. runs, so that a component to be transported can be moved almost vertically, ie almost at a 90 ° angle, to the intended assembly position, which enables particularly good controllability and precise fitting of the component into the intended installation location.

In 1 it can be seen that the floor element 12th and the carrier element 16 enclose an angle in the range of 45 ° to 85 °. In the preferred embodiment shown, this angle is 81 °, which is a particularly good compromise between a space-saving arrangement, which also allows the components to be transported through narrow doors, and sufficient stabilization of the components by their own weight on that of the device 10th , has proven.

The cradle 18th is in the device shown 10th as a frame construction 28 formed on which the component to be transported can be arranged, so that it does not have to be moved relative to the base when lifting to the mounting height, thereby protecting more expensive components.
