Abstract

The invention relates to a car for an elevator, in particular for an outside elevator such as a construction hoist with a protective roof. The protective roof is from a first operating position, in which it limits an existing in the car loading space at least partially upwards, adjustable in a second operating position in which it releases the upwardly limited in the first operating position cargo space at least partially upwards.

Description

The invention relates to a car for an elevator, in particular an outside elevator, as used for example as a construction hoist, goods lift or as a transport platform on construction sites, with a protective roof.

Exterior elevators are used, for example, on construction sites of building construction to transport people and / or material in the upper floors of the building to be built or renovated. For example. Construction hoists are also used for scaffolding construction.

Material lifts are usually designed exclusively for the transport of goods without accompanying persons. The transport of persons in the car is not allowed in this case.

However, there are also construction hoists such as so-called transport platforms, which are primarily intended for the transport of goods, but in which trained lift drivers may accompany the transport of goods together with other persons and may stay in the car while driving. However, such construction hoists must comply with special requirements with regard to the safety of the persons to be transported.

Other construction elevators, which must meet particularly stringent safety precautions, are approved for the transport of untrained persons and material.

Exterior elevators, which are approved for the transport of persons, regularly have a protective roof located above a loading space of the car as protection for passengers traveling against falling parts. However, such a canopy is a hindrance in certain situations, for example. When loading the car with material, due to its size and bulkiness.

In view of the described problems, it is the object of the present invention to provide a car for an outside elevator, in which people are safe and protected transportable, and at the same time is easily accessible when it is used for load transport.

This object is achieved by the car described in claim 1. Further developments and advantageous embodiments of the invention are the subject of the dependent claims.

The protective roof of the car according to the invention is from a first operating position in which it limits the loading space provided in the car at least partially upwards, adjustable in a second operating position, in which it is in the first operating position upwardly limited cargo space at least partially upwards releases.

In other words, the protective roof in the first operating position is arranged above the car floor in such a way that it covers the persons accommodated in the car and thus provides protection against parts falling from above. In contrast, the protective cover in the second operating position is arranged such that an existing above the car floor loading space is not or only slightly covered by the canopy. In other words, that part of the cargo space which is covered by the protective roof in the first operating position is at least partially open towards the top in the second operating position. This has the advantage that the Car can also be easily loaded and unloaded from above, and that on the other long-stretched goods such as long tubes or scaffolding parts can be placed upright on the car floor, without hitting the shelter or be hindered.

In the first operating position, the protective roof preferably covers the loading area of the car more than 50%, particularly preferably more than 80%, in particular complete, and in the second operating position preferably less than 50%, particularly preferably less than 20%, in particular not at all. In this case, the protective roof can have an area which essentially corresponds to or even is greater than one area of a car floor, and in the first operating position the protective roof can run substantially parallel to the car floor.

The invention is based on the recognition that a roof-free car, as it is regularly used in pure goods lifts, for transporting bulky, voluminous and / or extra long loads is significantly better suited than a set up for passenger transport car with protective roof, because the protective roof limits the available cargo space at the top. However, the complete disassembly of the canopy to convert the car from passenger transport to the transport of loads is time consuming and cumbersome. However, because the canopy according to the invention is adjustably set, a change from a passenger transport platform (operating mode passenger lift) with protective roof to a "roof-free" material handling platform (operating mode material lift) quickly and easily possible.

Preferably, the protective roof is arranged in the first operating position above a car floor and extends substantially horizontally. In the second operating position, however, the protective roof can run substantially vertically. A horizontally above the car floor running roof offers good protection against falling parts. A vertically extending roof, which preferably runs substantially parallel to one of the side walls of the car, barely impedes the loading space and allows the transport of elongated components in the car.

With regard to a space-saving arrangement of the protective roof in the second operating position, it has proven to be expedient that the protective roof in the second operating position at least partially forms part of a rear or side wall of the car and thus can serve the leaning of building material. The displaced protective roof can extend one of the side walls or a rear wall of the car upwards, so that an elongated member can be conveniently leaned against this extended side wall.

With regard to a structurally simple and quickly adjustable arrangement of the protective roof, it has proved to be advantageous for the protective roof to be pivotable or tiltable from the first operating position into the second operating position about a preferably horizontally extending pivot axis. Conversely, the protective cover can also be pivoted or tilted from the second back into the first operating position.

An advantageously designed folding mechanism for adjusting the protective roof provides that the protective cover can be folded down from the first operating position by about 90 ° downwards in the direction of a rear or side wall of the car. The rear wall may be the mast side wall of the car.

To prevent unintentional adjustment of the protective roof, at least one securing element, such as a screw for securing the protective roof, may be provided in the first operating position and / or in the second operating position. In this case, the protective cover is adjustable only after loosening the securing element or securing elements. An appropriately designed security element can additionally prevent an unauthorized person from folding the protective roof.

In order to maximize the flexibility of loading the car, the canopy can be detachably attached to the car. In other words, the protective cover can be completely removed from the car when needed, for example. When particularly bulky goods are to be transported.

The transport of particularly elongated goods by means of the car can be simplified if the canopy is adjustable from the second operating position to a third operating position in which it is at least partially further away from the car floor in the direction of gravity at least in the second operating position. In this case, the goods to be transported can be leaned against the portion of the protective roof remote from the car floor, so that overflowing of the goods can be reliably prevented.

The adjustment of the protective roof in the third operating position can be done by offsetting the protective roof, starting from the second operating position in the vertical direction. For example. For example, the protective roof, which preferably extends essentially vertically, is pushed vertically upwards by a predetermined amount and fastened in this position to a fastening section of the car. For this purpose, the car and / or the shelter can have a guide. In the third operating position, the protective roof can be secured by means of a securing element, such as a screw or a bolt. The further the upper portion of the protective roof in the third operating position is removed from the car floor, the longer components can be leaned against the protective roof without the risk of tipping over in the loading space of the car.

In this context, an offset of the protective roof between the second and the third operating position of more than 30 cm and less than 150 cm, preferably more than 50 cm and less than 100 cm, in particular of about 60 cm has proven to be advantageous. In other words, the protective cover is displaceable upwards by about 60 cm and can be fixed in this position. A displacement by this length is sufficient to safely accommodate scaffolding poles and scaffold floors usual length in the hold of the car can.

In order to facilitate the loading and transport of elongated goods in the car, it has proven to be advantageous to provide a holder attached to the protective cover for holding building material such as scaffolding parts or pipes in the second and / or third operating position. Goods such as scaffolding parts can be attached to the holder and / or secured to it, so that their tipping is prevented during transport.

The holder may be arranged to be folded on a surface of the protective roof, which is directed in the folded-down operating position in the direction of the car interior. In the first operating position of the holder may be folded into contact with the canopy so that it does not protrude outwardly from the surface of the canopy to the outside, while it can be folded in the second operating position such that against the displaced canopy leaning loads attached thereto or can be fixed.

Further, the holder or the like one or more holding parts such as handrails, tethers, chains or the like. have, prevent the tilted against the canopy leaning material, slipping or the like.

In a particularly preferred embodiment of the invention covers the canopy in the second and / or third operating position arranged on the car control element of the elevator. Then the elevator with the car according to the invention can no longer be controlled from the car, when the canopy is in the "operating mode material lift", ie in the second or third operating position. In these operating positions, a passenger transport is not provided because of the risk potential without a protective roof.

According to a further, particularly important aspect of the invention, the protective roof is adjustable from the first operating position, from the second operating position and / or from the third operating position by pivoting about a substantially vertical pivot axis into a further operating position. In particular, starting from the third (or second) operating position, in which the protective roof is arranged substantially in a vertical plane, the protective roof can be pivoted through the loading space about a vertical axis, the vertical axis being projecting upwards from a carcass corner Linkage part can be formed. Due to this further pivoting the protective roof, which due to its bulkiness in some circumstances in the second or third Operating position hinders a loading and / or unloading of the car to be brought in a more flexible way out of the way.

In the car of the construction elevator, scaffolding parts and mast parts are alternately transported, in particular, during the construction of a scaffolding. Whenever the scaffold has gained a certain height, the mast of the elevator can be raised by a corresponding height. After the mast has been raised, the subsequently required scaffolding parts can in turn be conveyed higher upwards with the car, which simplifies the scaffolding structure. In this way, the scaffolding and the elevator mast are alternately erected to a desired final height. However, the mast structure can be obstructed in the second and / or in the third operating position by the downwardly folded protective cover, which closes a rear side of the cargo space, on which the car faces the mast.

In view of a simplified mast structure, it has therefore proven to be expedient that in the further operating position an upwardly open window is formed on a rear side of the cargo space. Through this open-topped window, the mast parts can be mounted directly on the mast top to increase the mast. In the further operating position, the loading space is preferably fully released at the top. After completion of the master reinforcement, the protective roof for the transport of scaffolding parts can in turn be pivoted inwards around the vertical axis into the second or third operating position, so that the scaffolding parts can be ajar against the protective roof forming the rear wall of the car and can be accommodated in the scaffolding holder attached thereto , In other words, in the further operating position, at least an upper part of a rear side of the loading space, which faces the mast, is released.

Preferably, the protective roof is pivoted from the second or third operating position by 90 ° or more in the further operating position, so that it is no longer located above the car cabin and no longer represents any obstruction.

With regard to the provision of both a Verschwenkungsmöglichkeit about the vertical axis in the further operating position and a Verkippmöglichkeit about the horizontal axis starting from the first operating position, it has proved to be advantageous that the canopy in the other operating position at only a single stop point with the Car cab is connected. This stop point is preferably formed at the upper end of a corner linkage of the car. On the other hand, the protective roof in the other operating positions, in particular in the first operating position, be connected via more than one stop point, in particular two or more stop points with the car cabin. These two stop points can be arranged at the upper ends of two corner bars of the car on the mast side of the car.

The invention further relates to an elevator, in particular an external elevator, construction hoist and / or material hoist with a car according to the invention.

In the following description, the invention will be explained with reference to the accompanying drawings. In the drawing shows:

• Fig. 1 a perspective view of a car according to the invention, in which the protective roof is set in the first operating position,
• Fig. 2 a perspective view of the car Fig. 1 in which the protective roof is set in the second operating position,
• Fig. 3 a perspective view of the car Fig. 1 in which the protective roof is placed in the third operating position, and
• Fig. 4 a perspective view of a car according to the invention, in which the protective roof is placed in the further operating position.

In Fig. 1 is an inventive car 10 of an external elevator such as a construction site hoist or a transport platform shown in a perspective view.

External elevators regularly have a guide which can be fastened to a wall of a building and thus regularly extends in the vertical direction. The guide consists of one or two mast towers, on which / the car 10 can be moved movably. The car 10 serves to accommodate the persons to be transported and the goods to be transported. The mast towers serve to guide and move the car. As a rule, for this purpose at least one of the mast towers is provided with at least one toothed rack which extends in the longitudinal axial direction of the guide and in which a pinion of an electric traction drive engages. In such elevators, the travel drive is thus accommodated in the area of the car and is thus moved along with the car. The car according to the invention is equally suitable for outdoor lifts with other drive or mast arrangements.

The car 10 according to the invention may be of a "operating mode passenger lift", the in Fig. 1 is shown in a "operating mode material lift" to be adjusted in the FIGS. 2 and 3 is shown. In the passenger lift operating mode, passenger and goods transport is possible, while in the material lift operating mode, only goods are to be transported.

The car 10 has an adjustable roof 20, which in an in Fig. 1 shown first operating position (I) is arranged above a car floor 12 and limits the loading space of the car at the top. In the first operating position (I), the roof 20 extends substantially horizontally and thus protects persons transported in the car 10 from falling objects. With regard to the safety of the persons to be transported in the car, the roof 20 has a substantially closed material layer, such as a metal sheet, which reliably holds or at least deflects falling objects. The closed material layer can be attached to retaining struts. However, in the first operating position (I), the roof 20 prevents the reception of elongated goods and components such as pipes or scaffolding parts in the car.

The roof 20 can from the first operating position (I) in the in Fig. 2 shown second operating position (II) are adjusted, in which substantially the entire load compartment of the car 10 is open at the top. The adjustment takes place by tilting the roof 20 downwards about an axis of rotation A. Since the loading space in the second operating position (II) is not limited at the top, even elongate components such as scaffolding parts and pipes can be transported in the car. For this purpose, the elongated components can be leaned against the folded roof 20, which can form part of the rear wall 14 of the car in the folded position. In particular, the roof 20 extends substantially vertically in the second operating position (II), wherein an upper portion 26 of the roof 20 projects further up than the remaining side walls of the car.

The roof can be moved from the second operating position (II) to the in Fig. 3 shown third operating position (III) are adjusted. For this purpose, the roof 20 is offset by more than 30 cm, in particular by about 60 cm in a vertical upward direction, so that an upper edge 26 of the roof 20 protrudes particularly far upwards. Against this upper edge 26 components such as pipes can be leaned without the risk of tipping over.

In each operating position (I, II, III), the roof 20 can be secured by means of securing elements, such as in each case two or more screws or bolts, so that it can not be accidentally released.

In addition, the roof 20 can also be completely removed from the car 10, for example, if particularly bulky loads are to be transported.

At a in the first operating position upwardly facing surface of the roof 20, a holder 22 is attached in the form of a fold-out scaffold holding device. When the holder is folded out in the second or third operating position (II, III), holding parts 24 protrude in the form of holding rods in the direction of the loading space, wherein on the holding parts 24, the components to be transported can be supported or fixed. In particular, elongated components can be secured to the holder 22 against tipping or slipping. Depending on shape and weight the components to be transported 60, the holder 22 may also be designed differently and, for example, be mounted at a different height or other or additional holding elements such as hooks, chains, ropes o. The like. Have.

In the second and third operating positions (II, III), the roof 20 conceals a control provided in the car for controlling the elevator, so that the elevator can be controlled from the car only in the first operating position (I). Only in the first operating position (I) is the car namely intended for passenger transport.

Starting from the in Fig. 3 shown third operating position (III), the canopy about a vertical axis V in the in Fig. 4 shown further operating position (IV) can be pivoted. In the further operating position (IV), the protective roof no longer forms part of the rear wall 14 of the car, so that components 60 to be transported can no longer be attached to it. Rather, the upper part of the rear wall to form an upwardly open "window" 50 in the direction of a mast 55 arranged behind it open. In addition, the load compartment is completely open at the top. Through this window mast parts can be placed directly on a mast top to change the height of the mast 55. When fattening mast parts can be removed through the window 50 open at the top and be added directly in the hold of the car. For the transport of scaffolding parts or other components 60, the canopy in turn in the in Fig. 3 shown third operating position (III) are pivoted, in which the components 60 are receivable in the holder 22. The protective roof is consistently arranged substantially in a vertical plane.

For pivoting, a joint is arranged in an upper section of a corner post 58 of the car 10, via which the protective roof 20 is connected to the car cabin. In the other operating position (IV) this joint is the only stop point of the protective roof 20 on the car 10. In the other operating positions, however, the canopy 20 via at least one further stop point 59 with the car cabin, for example. By means of a hook or Connected spring bolt. A spring latch is particularly quickly and easily solvable by being pulled out of a corner post and twisted into a release position.

The invention is not limited to the embodiment shown. For example. The protective roof is not necessarily folded down about a rotation axis, but can also be brought in other ways in a substantially vertical position in which it releases the cargo space upwards. Alternatively, the holder is not hinged integrated into the roof, but can be fixed to the roof or attached as needed or dismounted. Furthermore, the protective roof can also be pivoted directly from the second operating position into the further operating position, without necessarily having to be moved upwards beforehand.
