Definitions
- the present invention refers to an entrance device according to the preamble of claim 1 and a staircase device according to the preamble of claim 17.
- the object of the present invention is to provide a device remedying the above-mentioned problems.
- it should be mountable and dismountable in an easy manner and in such a way that it may be used several times.
- the device is to be flexible in such a manner that it may be adapted to very varying conditions, for instance varying level differences between the entrance and the ground level.
- the support member comprises a bracket having two legs provided in an essentially perpendicular relationship to each other, one of which is arranged to be attached to a wall of the house or the like by means of an attachment member and the other is arranged to support the frame member.
- the attachment member may thereby comprise a longitudinal element insertable in an opening of the leg of the bracket which is arranged to support the frame member.
- the attachment member may advantageously comprise a hook-like member facing away from the longitudinal element and being arranged to be introduced into a cavity in the house or the like and fasten in a beam of said house.
- Such an embodiment of the attachment member is particularly suitable for such working houses piled onto each other that are used at building sites.
- the legs of the bracket comprise a hollow square profile. Such a square profile results in a good stability and strength of the bracket and one may simultaneously provide a great abutment surface for the leg arranged to be attached to the wall of the house or the like.
- the frame member comprises four side pieces connected to each other to a quadrangle and the flange member comprises a flange piece projecting from each side piece towards the centre of the frame member.
- the four flange pieces form a surrounding flange directing inwardly. Beside the fact that such a flange is a stable substrate for a step plate, it also contributes to a further raised strength of the frame member and thus to an improvement of the self-supporting capacity.
- the frame member is manufactured in aluminium, steel or any similar high-strength material.
- the entrance device has a staircase comprising a connection part arranged to be suspended onto the frame member.
- the connection part may comprise a first portion arranged to extend along the outer side of a side piece of the frame member and the second portion connected to the first portion and arranged to extend along the inner side of the side piece.
- the staircase is extendible.
- temporary houses and dwellings the height between the ground level and the entry of the house varies.
- the staircase may comprise two opposite side pieces and one or more stairs provided between the side pieces, a loosely attachable extension piece having two extension side pieces and at least one stair provided therebetween, and two connecting pieces, each of which is provided to be loosely attached to a side piece and an extension side piece.
- each connecting piece is essentially plane and abuts a side piece by a first portion and abuts an extension side piece by a second portion in such a manner that these side pieces are aligned with each other.
- the staircase may in an easy manner be provided with a suitable number of extension pieces necessary to adapt the length of the staircase to the height conditions prevailing.
- the side pieces and the extension side pieces have in cross-section an essentially U-shaped profile with a bottom and two legs.
- the connecting piece is provided between the side pieces and the stair against the inner side of the bottom of the U-shaped profile. In such a manner, the connecting piece will not be visible when the staircase is mounted but the side of the side pieces facing outwardly will be essentially even.
- each connecting piece is kept together with two associated side pieces by means of through-going screw bolts at least one of which extends through a side piece, the connecting piece and into the stair.
- the staircase device initially defined and comprising the characterizing features defined in claim 17.
- an entrance device is provided, which in a flexible manner may be adapted to varied level differences between the ground level and the plane at which the entry of a house or the like is located.
- Preferred embodiments of this staircase device are defined in claims 18 to 21 .

- Fig 17 discloses in a sectional view the mounting of the railing to the frame member.
- Fig 1 discloses an entrance device according to the present invention.
- the entrance device is intended to be attached to a house 1 or the like.
- the expression "house” is used. It is to be noted that this expression refers to all possible buildings of more or less temporary kind, for example the working houses disclosed in Fig 1 and piled onto each other, evacuation dwellings and similar barracks, public buildings such as day nurseries and kindergartens, summer houses and at other places where an entrance device or staircase is necessary for giving access to an entry or the like which for instance is located at another level than the ground level.
- the entrance device disclosed in Fig 1 comprises a staircase 2, having an extension piece 3 and a railing 4, and a platform 5 provided horizontally and having a railing 6.
- the lower platforms 5 disclosed in Fig 1 are in principle constructed in the same way as the upper platform 5.
- One of the lower platforms 5 has a support in leg 7 and a shorter staircase 2.
- the other lower platform 5 discloses a slightly sloping ramp 8 suitable for a wheel chair.
- the upper platform 5 is supported by means of support members 9.
- the supporting member 9 disclosed in Fig 1 is now to be explained more closely with reference to Figs 2 to 4.
- the supporting member 9 comprises a bracketIO having two legs 10a and 10b.
- One of the legs 10b is arranged to abut the wall of the house 1 and the other leg 10a is arranged to project essentially perpendicularly from the wall of the house 1.
- the leg 10a as well as the leg 10b have the square hollow cross-section disclosed in Fig 4.
- Fig 4 discloses a square cross-section, it is also possible to make the legs 10a, 10b in a more rectangular shape.
- the legs 10a, 10b of the bracket 10 may be manufactured in preferably extruded aluminium, which is advantageous since it is a very light material.
- the bracket 10 is fixed to the wall of the house 1 by means of an attachment member 1 1 having a longitudinal element 12 which is disclosed inserted in an opening at the end side of the leg 10a.
- the attachment member 1 1 is fixed to the leg 10a by means of a bolt 13 extending through a first flange 14 provided on the attachment member 1 1 and a second flange 15 provided on the leg 10a.
- a nut 16 provided on the bolt 13
- the flanges 14 and 15 are tightened against each other and the attachment member 1 1 is pulled into the leg 10a.
- the attachment member 1 1 has a hook-like member 17 intended to be fastened to the house 1.
- the house 1 is comprised of working houses piled onto each other and these rest on beams 18. Between a beam 18 of an upper house and a house therebeneath there is an intermediate piece (not disclosed) which provides a distance between the beam 18 and the house 1 therebeneath.
- the hook-like member 17 of the attachment member 1 1 may be arranged by being rotated 90° in relation to the orientation disclosed in Fig 3 and pushed in between the beam 18 and the house 1 therebeneath. Thereafter, the attachment member 11 is rotated back and the hook-like member 17 is fastened to the beam 18, as is disclosed in Fig 2. It is to be noted that the attachment member 1 1 may have many different kinds of fixing members arranged to be fastened to different types of houses and buildings etc.
- the bracket 10 is thus rigidly fixed along the wall of the house 1.
- a further attachment member may, however, be provided at the lower end of the leg 10b, for instance screws (not disclosed) extending through the leg 10b and into the house 1 .
- the bracket 10 may not be turned, possibly resulting in the detachment of the hook-like member 17 from its mounting location.
- a frame member 19 rests above the bracket. The frame member 19 is fixedly located on the bracket 10 by means of a mounting member 20.
- the frame member 19 and the mounting member 20 are now to be described more closely with reference to Figs 5 to 7.
- the frame member 19 comprises four side pieces 21 connected to each other. Each side piece has a flange 22 directed inwardly towards the centre of the frame member 19.
- Each side piece 21 together with its associated flange 22 may be manufactured in one piece, preferably extruded aluminium. These pieces may then be welded to each other in the four corners of the frame member 19.
- a number of step plates 23, for example four may be inserted in such a manner that they rest against the flange 22.
- the step plates 23 may be manufactured in extruded aluminium, but also other materials are possible, for example steel plate or wood duckboards which may be inserted in the frame member 19.
- the mounting member 20 comprises a bottom plate 24 and two support plates 25 between which one of the side pieces of the frame member 19 is inserted. By means of one screw 26 provided in the outer support plate 25, the side piece 21 may be pressed against the other support plate 25 and be fixed to the mounting member 20.
- the bottom plate 24 has an elongated hole 27 for a screw 27a by means of which the mounting member 20 is fastened in the beam leg 10a. Because of the elongate shape of the hole 27, the mounting member 20 may be displaced laterally, in such a manner that the frame member 19 always may be inserted between the support plates 25, although a joint between two frame members would be located at the mounting member 20.
- the staircase 2 together with the extension piece 3 disclosed in Fig 1 is now to be explained more closely with reference to Figs 8 to 14.
- the staircase 2 is disclosed in Fig 8. It comprises a number of stairs 28, see Fig 1 1 , and two side pieces 29, see Fig 12.
- the stairs 28 as well as the side pieces 29 may advantageously be manufactured in extruded aluminium, steel plate or any other high-strength material.
- the stairs 28 have a rough surface 30 provided on the upper side, which act as slip protection.
- the stairs 28 On the under side the stairs 28 have for instance three downwardly directed flanges 31 each of which has a downwardly open cavity 32 extending along the length of the stair and which may be provided with threads.
- the previously mentioned step plates 23 may have a profile similar to the one of the stairs 28.
- the step plates may be fixed in their position in the frame member 19 by means of screws or some kind of snap elements, for instance, (not disclosed), which engage the cavities 32.
- the side pieces 29 ought to have a high strength. They may therefore have a cross-section profile being stiff with respect to twisting, for example an L-shape, a Z-shape, a U-shape etc.
- the side pieces 29 have a U-shaped cross-section with a bottom and two legs being relatively short in relation to the bottom.
- the side piece 29 has rows of three holes 33 which are provided at the same mutual distance as the cavities 32.

- the connecting part 34 has a first portion 35 arranged to extend along the outer side of a side piece 21 of the frame member 19. This upper portion 35 is bent 180° and thus forms a second portion 36 arranged to extend along the inner side of the side piece 21.
- the staircase 2 may in a secure manner be hooked onto the frame member 19.
- the staircase 2 is extendible by the extension piece 3 disclosed in Figs 1 and 13. This piece comprises two extension side pieces 37, which have the same cross-section profile as the side pieces 29, and a stair 28 provided therebetween.
- the extension piece 3 comprises two connecting pieces 38, see Figs 13 and 14.
- the connecting pieces 38 are provided with a number of through- going holes, at least one of which is provided in the centre in such a manner that a screw 39 may extend through the extension side piece 37, the connecting piece 38 and into a cavity 32 of the stair 28 of the extension piece 3.
- the two upwardly projecting connecting pieces 38 are simply inserted into the two U-shaped opposite side pieces 29 of the staircase 2.
- the side piece 29 of the staircase 2 is screwed together with the connecting piece by means of screws (not disclosed).
- several extension pieces 3 may be provided one after the other and in such a manner that the total length of the staircase 2, 3 may be adapted to all practically existing heights.
- the railing 6 disclosed in Fig 1 is now to be explained more closely with reference to Figs 15 to 17.
- the railing 6 comprises pieces having a length corresponding to the length of the frame member 19.
- Each such railing piece comprises two upwardly projecting support members 40 and a transverse handrail 41.
- a further transverse support member 42 may be provided between the two support members 40.
- the two support members 40 have at their ends a through-going hole through which a screw 43 extends, which also extends through a hole in the side piece 21 of the frame member 19 and is fixedly tightened by means of a nut 44.
- the railing may be provided with a cover plate 45 provided between the support members 40.
- all disclosed parts of the device according to the invention may be utilized as universal module elements, which may be adapted to all practically existing conditions by being built together in different manners.
