Description

The present invention relates to a device for a frame-shaped conveyor for the transport of cargo in connection with buildings, where the conveyor comprises a conveyor track to form a connection for the cargo transport through an opening in a wall in the building, as well as support means for stabilizing the conveyor, such it appears from the introduction in the subsequent claim 1.

More specifically, the invention is concerned with a construction for the transfer or transport of goods such as building articles into and out of buildings, or which, for example, are to be transported internally in a building complex, i.e. that loads are to be transferred between different parts of the complex. In particular, one thinks of buildings that are under construction or rehabilitation. But the construction can also be used in connection with existing and older buildings where building materials or other types of objects are to be transferred internally between different departments in the building.

Another current situation is when residents have to move in or out of a building, and where there is then a need for transport in/out of the building, e.g. of heavier furniture and furnishings of various kinds. Often household items can be larger than what can be carried up/down stairs, or taken into the ordinary building lift. The only thing that limits what can be transported out/in the building is the size of the opening. The invention has particular relevance for the transport mentioned above, for objects that are too long or too heavy to carry up and down stairs.

Construction goods generally mean all materials and furnishing objects such as wall sections, doors, packages of wallboards, parquet and floorboards, construction materials, tiles, cement sacks and other heavy materials for masonry and all other equipment that is necessary for the work on new building works. But it can also include fixtures such as furniture and wall-mounted items in connection with bathrooms and kitchens.

It is often a challenge to transfer such building materials from cargo vehicles such as lorries/trailers into a building. The challenges increase with the number of floors. During the construction of the building, the load is brought in through openings in the building which are ready for the installation of frames for the insertion of windows and doors etc. The load is lifted up to the window opening with a crane and maneuvered and balanced in through a relevant opening in the wall.

It is also known to use various permanent crane systems to lead loads in and out through the frames, cf. as shown in US Patent Application US-2002/0084238 and Canadian Patent Specification CA-678,782. These solutions are based on the fact that the crane includes a boom that can be moved horizontally so that the load enters safely through the openings in the wall. However, these cannot be used to tap in anything other than (or it is limited to) what you can fit in the bucket/basket that hangs at the end of the wire.

On all levels of the building, i.e. also in connection with floors higher up, it is common to use manual handling, i.e. that the materials are carried by crane halfway into the opening and lowered onto the frame. Then must e.g. carpenters lift and ease materials and equipment in and out through the openings by hand. The manual method is time-consuming, since material packages often have to be split up and the contents, such as planks etc. must be drawn in in smaller numbers, one by one plank, at a time. Another important point is that the carpenters who have to struggle to drag the materials into the window get back problems, and that crushing injuries can easily occur with this way of working.

Another major disadvantage of the known solutions is that damage to the window frames easily occurs when the materials have to be eased in. Damage to frame parts in the building occurs when the materials are pulled in through the window directly. The crane operator often places the materials directly on the frame, and they are pulled in. This method can even lead to damage to the entire outer wall as there is a risk of pulling it crooked as a result of the moment that occurs during the movement of heavy material packages.

A disadvantage of this is also that the transport vehicle often has to be parked further down the street to carry out the unloading. This increases the client's costs, which of course depend on the time elapsed for the delivery. As well as the fact that in narrow streets this transport operation can block traffic for an unnecessarily long time, and also that pedestrians have to walk around the crane vehicle to get past, and are thus forced out onto the roadway.

It is an aim of the invention to produce a new construction for the transport of building materials into and out of buildings which is safer, more efficient and not least time-saving compared to current solutions.

It is also a particular purpose of the invention that a transport track is established through a building opening for a window, door etc. and which should not touch the surface part of the frame and expose it to damage when heavier building parts are transported through the opening.

It is further an object of the invention that the construction is so robust that the building parts can be passed through the opening in a normal "rough" manner without the operator needing to be concerned about the frame parts being damaged by transport.

It is also important that the supports are placed so that they form abutment against the building's supporting structure in the wall at all times so that the building does not suffer damage. The same applies to the supports that will form structures against the floor and ceiling.

In wooden house constructions, you must therefore be clear about and check which way the load-bearing joists go. If the supports cannot be placed for installation directly on the stud structure, a suitable plank can be laid across the beam layer to distribute the forces from the load.

It is therefore an object of the invention that the transport device according to the invention does not come into contact with the frame parts.

The device according to the invention is characterized by the fact that the support members in the framework include adjustable leg and arm parts with support paws which can form clamping systems against opposite side surfaces of the wall to hold the framework for the transport track at a distance A above an upward facing side of the frame in the wall opening.

According to a preferred embodiment, the support members are telescopically extendable, and the conveyor also includes support legs to form stabilizing clamping systems against floor and ceiling surfaces.

According to yet another preferred embodiment, two support paws are aligned with each other so that they function to grasp and clamp against the wall with a claw action against the oppositely directed wall sides, thereby ensuring that the underside of the frame is permanently held at the aforementioned safe distance A from the upward facing the frame side surface, so that it is not damaged.

According to yet another preferred embodiment, the frame part which is located on the outside of the wall defines vertical and inclined support struts and which together carry a fixedly mounted vertical support paw arranged to be braced against the outer wall.

According to yet another preferred embodiment, the conveyor's transport path comprises a frame part on which rests a transport roller frame on which a load can be pushed over and into through the opening, preferably comprising a number of elongated and rotatable rollers which are arranged parallel to each other at a uniform distance, whereby a load can be pushed along the runway and into the opening.

According to yet another preferred embodiment, the conveyor frame, in relation to the building wall, comprises outer and inner arm support parts including associated support paws which are flush with each other so that they function to grasp and clamp against the wall with a claw effect.

According to yet another preferred embodiment, one of the arm support parts is stationary, while the other is adjustable.

According to yet another preferred embodiment, the frame on one side of the wall comprises two pairs (four pieces) of leg supports arranged in a square pattern, the one pair of leg supports with associated support paws being arranged to be extended to form abutment against a ceiling surface.

According to yet another preferred embodiment, each leg in the pair of leg supports comprises a horizontally oriented extendable arm with associated support paws arranged to form abutment against a vertical wall part when said leg parts in the pair of leg supports are clamped firmly between floor and ceiling. In those cases where the support legs cannot be placed directly on the building's supporting structures, a suitable beam of iron or wood is arranged across the beam layer to distribute the forces from the load.

For adaptation to different widths and heights of openings, the construction is two-part vertically for horizontal displacement, in that the frame construction is split (vertically) into 2 parts by mutually adapted sliding telescopic parts.

According to the invention, the conveyor device defined above is used to transport loads out of and into buildings and/or internally inside buildings through openings in the building structure, to prevent the load transport from causing damage to the building components.

The invention will subsequently be described in more detail, with reference to the attached figures, in which: Figure 1 schematically shows a vehicle that lifts a load of materials into the 3rd floor of a building, through a window opening where the inventive construction is mounted. Figure 2 schematically shows a more detailed and enlarged perspective of the construction seen from above mounted to the window opening. Figure 3 shows a vertical section of the inventive construction securely attached to the building structure adjacent to a window opening. The figure also shows an enlarged section of a significant detail. Figure 4 shows in a perspective view (seen from behind) all the central parts of the construction according to the invention. Figure 5 shows how the construction according to the invention can be adjusted in width to adapt to different openings in the building.

Initially, reference should be made to Figure 1, which shows a building 110, for example, under construction. A truck 100 with a crane 102 stands at ground level 104. The crane 102 lifts a load 106. The inventive construction 10 is mounted adjacent to the opening 17 for a window on a third floor 18 of the building 110. The window openings for the first 14 and second 16 floors are indicated by 13 and 15, respectively. The building's wall 20 and two of the floor dividers (floors) 19 and 21 between the first and second floors and between the second and third floors are shown. On the floor 21 inside the third floor 18, there is a wheeled work and transport table 108 which is used to transport the materials to where they are going inside the building's third floor. The crane places the materials 106 onto the conveyor belt 30 of the construction 10, and the materials 106 are further dragged onto the work table for further handling, and to free up space on the conveyor belt 30.

The enlarged perspective in Figure 2 shows more clearly the construction arranged through the opening 17. Cf. the details that are explained in connection with figures 3 and 4. The construction is stabilized in position by means of support rods stretched between the floor and ceiling in the room inside the wall, and by means of horizontally oppositely directed support legs which, externally or internally, fasten it to the wall 20.

The device according to the invention shall be further explained in connection with the vertical section in Figure 3 and the perspective view in Figure 4.

The transport device according to the invention is a construction composed of a truss frame which includes support members which stabilize the construction against the storey's floor surface 21, roof (ceiling) 121 and the wall parts 20, as well as including members which ensure stability by forming structures against the outer surface 25 and inner surface 23 of the outer wall 10.

The construction 10 comprises an upper frame part 32 on which rests a transport roller frame 29 which is composed in a known manner of a number of elongated and rotatable rollers 30 which are arranged parallel to each other at equal distances. A load (106 in Figure 1) which is to be moved forward is simply pushed along the runway 30 and in through the opening 17.

The upper frame part 29 forms the top part of the truss frame which comprises rear and front pairs of vertical floor support legs 74 and 76. The rear floor legs 74,76 are wide plates which form a bearing against the floor, and are mounted on the end of respective shaped telescopic floor struts 69 and 71 which can respectively be pulled out telescopically from and pushed into the rear main legs 70 and 72.

The opposite end of the rear main legs 70,72 includes corresponding telescopically extendable roof support struts 50 and 52 respectively, the ends of which include roof support legs 54 and 56 arranged to rest against the ceiling/ceiling 121 in the floor divider 22. The telescopically extendable parts are used to brace up and stabilize the framework between ceiling and wall.

In addition to the rear leg parts 70,72, the frame also includes front leg parts 80 (not shown) and 82 with corresponding extendable telescopic legs 85 (not shown) and 87 which, via two plate-like front support legs 84 (not shown) and 86, rest against the floor surface 21 The frame thus rests on the floor with its four legs 70,72, 80 and 82.

In the upper part of the vertical leg parts 70,72, two mutually horizontally projecting wall support arms 60 and 62 are arranged with corresponding telescopically extendable arms 59,61 whose outer ends include the plate-like support paws 64,66 designed to rest and support the construction against the inner wall 23 on each side of the window opening 17.

The main point of the construction is that the underside 33 of the frame part 32 should not touch the lower, upward-facing frame side 35 of the window opening. This distance is ensured primarily by the fact that the frame includes two further pairs of support arms which are respectively designed to form a tension system against the inner wall 23 and the outer wall 25 of the building's wall 20 respectively.

For this purpose, the frame part 10 which is situated to the right on the outside of the wall comprises vertical and inclined support rods 36 and 37 respectively and which together carry a fixed vertically positioned support leg 42 designed to be tensioned against the outer wall 25. There are two such sets of support legs, one on each side of the frame.

Correspondingly, on the room side, adjacent to the two vertical leg parts 72 and 82, there is a support rod for a telescopically movable horizontal rod 102, the end of which comprises a vertically positioned support paw 106 designed to be clamped against the inner wall, below and to the side of the opening 17 in the wall.

The horizontal external support leg 42 fixed to the frame 10 and the adjustable (expandable) horizontal internal support leg 106 are arranged flush against each other on opposite sides of the wall. When the two internal horizontal support tabs, one on each side of the frame, are clamped against the wall, in addition to all the other support tabs mentioned above, a very good stable and secure stabilization of the entire frame is formed in relation to the window frame opening .

The two support paws 106 and 42 thereby form two claws that grip the wall, one on each side. This ensures that the underside 33 of the frame 10 is kept permanently at a safe distance from the upward-facing frame side surface 35 (figure 3), so that there is no risk of damage being caused to it.

All parts of the frame 10 according to the invention can comprise square tubes, and with telescopic parts designed to slide inside each other to brace the support legs against the floor, ceiling or wall surfaces.

All the telescopically extendable supports used in connection with the invention are clamped against floor, ceiling and wall surfaces in a manner known per se.

As explained in connection with the support leg 52 in figure 3, this happens by first loosening the tensioning lever 53 and then pulling the support 55 with the support paw 55 up/out until it forms contact with the ceiling 121. the building. It is then tensioned up using the tensioning lever 53 which engages in a groove in the support 52 and moves the rod 55 upwards, and which further compresses a powerful spring, and thus the support 52 is forced/tensioned out a few extra millimeters so that it remains in tension .

Correspondingly, all the expandable support struts in the construction according to the invention are tensioned.

The tensioning construction shown is only one of many ways of operating, ie releasing, cocking and locking, the telescopic tubes.

Furthermore, the framework is designed so that it can be adjusted both laterally and vertically, so that the device can be adapted to buildings with different widths and heights of the openings for windows, etc. as shown in Fig. 5.

As can be seen from Figure 5, the construction is designed to be split vertically into 3 parts: The transport roller frame 10a and 10b separately, and that the frame construction itself can be split into 2 parts 120A and 120B. This simplifies transport when, for example, the constructions are to be moved between floors , up and down stairs.

Where the two sub-sections 10a and 10b; 120A and 120B) meet, different dimensions are used on the square tubes, and thus the construction can be adjusted in width by pushing them one into the other. More precisely, the construction is such that the division is carried out in the pipe parts that form the conveyor belt frame, in the following way (see figure 5).

The two pipe parts 10 and 10a" in the left (in the figure) section 10a are arranged to be pushed in and out of the opposite pipe parts 10b' and 10b" in the right section 10b and can optionally be locked to each other.

At the same time, the two pipe parts 120A' and 120B" in section 120A are designed to be pushed in and out of the opposite pipe parts 120B' and 120B" in section 120B and can optionally be locked to each other.

When the desired width is achieved, the construction is locked at this width by screwing the roller board into the frame. The construction according to the invention can then be fastened to the building's roof, floor and walls.

The framework can be produced in a suitable quality in steel or aluminium, or other suitable material.
