Description of the Present Invention

Technical Problem

A problem is frequently encountered in conjunction with the design of a device for transporting the pipes and planks required for the erection of scaffolding. It is usual for scaffolding, which consists of vertical pipes and horizontal connecting pipes, to be erected without the help of a hoist.
Once the scaffolding is safely in position, it is not unusual to install a special passenger lift which is covered by the appropriate regulations, and at the same time to use a crane to raise building materials to the floor on which the workplace is situated and on which the material is to be used.
Consequently, a major problem is associated with the pronounced desire to produce a transport device of such a kind that it may be used both during the erection and dismantling of the scaffolding and for the transport of materials, preferably building materials, up and down during the construction work.

Solution

The present invention relates to a device according to the features stated in the preamble of claim 1.
In order to offer the possibility on the one hand of using the device for the transport of pipes and planks for use in the scaffolding, and on the other hand of using the device for the transport of materials up and down, the present invention proposes the features stated in the characterizing part of claim 1.

Techanical Advantages

The principal technical advantages which may be regarded as being associated with a device in accordance with the present invention are that the device has been designed in such a way that it may be quickly converted by simple means from being used for the transport of one kind of material up and down along a guide resting on a support area to a device enabling the transport of another kind of material up and down along said guide.
What may be regarded as the characteristic feature of a device for the transport of material up and down along a guide in accordance with the present invention is indicated in the characterizing part of the following dependant Patent Claims.

Description of the Preferred Embodiment

Fig. 1 shows a device intended for the transport of material up and down along a guide. The device consists of said guide 1 rigidly attached to a base plate 2 and secured partly by stays 3 and partly by clamps 4 attached to horizontal pipes 5' forming part of a scaffolding 5 with vertical pipes 5" and with planks 7 arranged between horizontal pipes 5'. The pipes 5' and 5" are attached to each other by means of clamps 8.
The base 2 rests on the ground 9, as does the scaffolding 5.
The guide 1 may best consist of a number of interconnected component parts enabling the guide 1 to be erected upwards or dismantled easily, depending on whether the height of the scaffolding is to be increased or decreased.
The device intended for the transport of material up and down along a guide consists of a frame construction 11 operated by a power plant 10, of which the displacement is controlled by a cable 12 which runs from the power plant 10 upwards and over a guide pulley 6 and then downwards, as shown by the reference designation 12a, with the end of the cable, which is not shown, being attached to a portion 11b' of the upper part 11 b of the frame construction 11.
The frame construction 11, which in Fig. 1 is covered by a plate 11', has at its lower end 11a a a first attachment arrangement 130, as illustrated in Fig. 8 as a spigot-and-socket joint, intended to operate in conjunction with an attachment arrangement 131 located in a support area 13 for a load.
At its upper end 11b is a second and a third attachment arrangement, as illustrated in Fig. 9. The third arrangement is intended to operate in conjunction with one end of a supporting arm 15, shown in Fig. 6, of which the other end carries a fourth attachment arrangement 16 intended for suspended loads.
Fig. 8 indicates that the first attachment arrangement 130 consists of two holes 132, each of which passes through a hollow metal section 17 attached to the frame 11, and two holes 131 in two hollow sections 18, said hollow metal sections being dimensioned so as to fit either inside or over each other, together with two pins, each pin 19 being capable of being inserted through both the hole 131 in the hollow metal section 18 and the hole 132 in the section 17.
The support area 13 is fitted with upward-facing sides with the reference designations 13a, 13b and 13c.
The third attachment arrangement 14, shown in Fig. 9, consists of a U-shaped groove 14a, with a hole 14b, which extends vertically, and one end 15a of the arm 15, which is also provided with a hole, may be inserted into the U-shaped groove 14a. A vertical pin 20 passes through all the holes and acts as a shaft enabling the arm 15 to pivot. (The attachment of the arm is not shown in Fig. 9.)
The fourth attachment arrangement, intended for suspended loads, consists of a load hook 16, preferably attached to the other end 15b of the arm so that it is free to rotate. The pivoting shaft formed by the pin 20 enables the arm 15 to move to a variety of positions, with the solid arm, shown in Fig. 6, illustrating the position used for the transport of material up and down along the guide 1, whilst the arms shown with dotted lines in Fig. 6 illustrate the manner in which the load may be swung over so that it may be lowered onto planks 7 forming part of the scaffolding.
The upper end 11 of the frame also has a second attachment arrangement 21 intended to operate in conjunction with two attachment arrangements 23 formed on a component 22 forming an upward extension of the frame and especially the plate 11'.
The second attachment arrangement 23, in the form of a spigot-and-socket joint, provided on the component 22 and especially on a frame behind the component 22 consist of two holes, each of which passes through one of the hollow metal sections 24, with sockets forming part of the component being so dimensioned as to fit either inside or over lengths of hollow metal section 25 on the upper end 11b b of the frame construction. Each length of hollow metal section 25 is provided with a hole 26, and a pin 27 may be inserted into the holes 26, 23 which operate in conjunction with each other.
The component 22, as may be seen from Fig. 1, consists of a frame with three vertical elements 28, 29 and 30 and with horizontal elements 31, 32, 33 and 34. One frame element 35 is attached to the element 30 at point 35a in such a way that it is free to move and is provided with a locking arrangement so that it may adopt the position indicated in Fig. 1. One frame element 36 is attached to the element 29 at point 36a in such a way that it is free to move and is so arranged that it may be locked in the position shown in Fig. 1. The same is true of frame elements 37 and 38. Frame elements 35, 36, 37 and 38 may be moved into a folded-up position.

Fig. 2 shows how the frame elements 36 and 38 have been moved to the folded-up position, thereby opening the component of the frame enabling a number of pipes 5" to rest against the support area 13, and how they are held in position by a control organ 39 attached to the upper end 22b of the component of the frame 22 so that it is free to move. The position of the control organ 39 in Fig. 2 shows that the pipes 5" may simply be positioned parallel to each other. The control organ is free to move and is able to adopt the position shown in Fig. 1 or the position shown in Fig. 2.
Fig. 3 illustrates how the control organ 39 is able to adopt an outward-facing position (similar to Fig. 1), enabling the planks 7 to be loaded and to rest against the support area 13 and a frame element 40, at the same time as the frame elements 38 and 36 are in a folded-up position.
Fig. 4 shows that the support area 13 has been removed from the lowest part of the frame and that the component of the frame 22 has been removed from the upper part 11 b of the frame 11 and that a supporting arm 15 has been attached to the second attachment arrangement 14. Fig. 4 shows a number of bricks 42 loaded on a trolley 41 suspended from the load hook 16, representing a load suspended from the attachment arrangement 16.
Fig. 5 shows a wheelbarrow 43 filled with mortar representing a load suspended from the load hook 16.

It should be noted that once the wheelbarrow 43 has been raised by the device to a height level with the person 44, the arm 15 may be pivoted about one of its ends 15a and about the pivoting shaft 20, enabling the wheelbarrow 43 to be swung across and positioned directly over the planks 7 supporting the person 44.
Fig. 7 shows a section through a guide profile, from which section it may be seen that the dimensions of the flat surfaces should be 50 mm in a preferred embodiment. The space 45 is intended for clamps or securing devices 4 between the guide 1 and the pipes 5', whilst the channels 45a and 45b are intended to accommodate connecting unions between two adjacent guide elements. The space 45c may also serve as a guide track and bearing surface for the frame 11 as this is displaced up and down along the guide.
The present invention is not, of course, restricted to the preferred embodiment indicated above by way of an example, but may undergo modifications within the scope of the following Patent Claims.
