Background art

In the construction of high rise buildings, the floors of the building are typically made from poured concrete. It is an advantage to control the drying process of the concrete to be able to build according to the preset time schedule or even to speed up this schedule. However, bad weather conditions such as rain, snow or too much sun heat can disturb the drying process and result in substantial delays of the subsequent building steps. A building under construction is therefore typically protected from rain and wind by a weather protective cover, such as a plastic webbing or a tarpaulin, which is attached to the scaffolding around the building. The weather protective cover may also prevent building material from falling out of the building. The weather protective cover is tied to the scaffolding and as the construction of the building progresses the protective cover needs to be repeatedly untied and reattached to protect newly constructed floors. This operation is cumbersome and requires both a substantial number of workers and a lot of time.

US4129197 shows a scaffolding system for erecting a safety fence around the floors of a building under construction. The scaffolding system comprises vertical standards which are attached to two adjacent floors of the building. The safety fence is slidable in slots in adjacent vertical standards. When the work on the first floor is completed, the lower half of each standard is detached and remounted on the upper half of the standard and attached to the second floor. The safety fence may then be slid upwards in the standards to the second floor. The scaffolding system of US4129197 facilitates the transfer of the safety fence as the construction of the building progresses. However, the dismounting and reassembling of the vertical standards is time consuming and the overall construction of the scaffolding is complicated and costly.

US2014339018 discloses a safety barrier netting system for protecting personnel working in a building under a construction from falling or to prevent objects from falling off the building. The safety net is carried by vertical uprights which are movable along the facade by engagement with rolls. However, in order to provide safety, the uprights needs to be securely held against the facade of the building in order to withstand outward directed forces from the floors of the building. For example, the impact of a person which stumbles and falls against the netting. To achieve this purpose US2014339018 relies on a solution in which the uprights comprises radial flanges which each are engaged between a pair of rolls. However, while firmly securing the uprights against the building, a drawback with this solution is that the flanges of the uprights may get pinched between the pair of rolls which in turn results in difficulties in moving the barrier netting along the facade of the building. The solution of US2014339018 is also dependent on complicated design of the uprights and several interacting rolls.

Thus, it is an object of the present disclosure to provide a weather protection arrangement for a building which solves or at least mitigates at least one of the problems in the prior art. In particular it is an objective of the present disclosure to provide a weather protection arrangement for a building which is of simple construction and that comprises few parts. A further object of the present disclosure is to provide a weather protection arrangement with a weather protective cover which may be easily moved along the facade of a building.

Summary of the invention

According to the disclosure, at least one of the above objects is achieved by a weather protection arrangement 100 for a building 200 comprising,

- a first and a second elongate upright 10.1, 10.2 configured to extend parallel to each other in vertical direction along the facade of a building; - a weather protective cover 20 extending between said first and second elongate upright 10.1, 10.2;

- a first and a second holder 30.1. 30.2, respectively configured to be attached to a floor 210 of a building and having a first and a second guiding means 40, 41 for guiding movement of the respective first or second elongate upright 10.1 , 10.2 in vertical direction along the facade of the building wherein,

- the first and the second guiding means 40, 41 are spaced apart on opposite sides of a longitudinal axis (X) extending parallel with the floor 210 of the building and through a first and a second end 31, 32 of each holder 30.1 , 30.2 characterized in that,

- each elongate upright 10.1, 10.2 comprises a first and a second external guiding surface 1 1, 12 extending in longitudinal direction on opposite sides of each elongate upright, and facing in opposite directions, wherein in use,

-the first and the second upright 10.1, 10.2 are received between the first and the second guiding means 40, 41 of a respective first and second holder 30.1 , 30.2, whereby the first guiding means (40) of a respective holder 30.1, 30.2 is in contact with the first guiding surface 11 of a respective elongate upright 10.1, 10.2 and the second guiding means 41 of a respective holder 30.2 is in contact with the second guiding surface 12 of a respective elongate upright 10.1, 10.2. According to the disclosure, the elongate uprights of the weather protection arrangement are guided in vertical direction by engagement between opposing external guiding surfaces of the uprights and spaced apart guiding means attached to the floors of the building. The weather protection arrangement may thereby be realized by a simple solution in which the guiding surfaces may be constituted by two opposing and parallel walls of an upright of hollow cross-section and two spaced apart rolls which engages the side walls of the upright. This results in a simple and light weight construction for moving the elongate uprights and thus the weather protective cover in vertical direction upwards along the facade of the building as the construction of the building progresses. Movement of the weather protection arrangement is further achieved with a minimum of effort and personnel. A further advantage of the weather protective arrangement according to the present disclosure is that it is realized with few parts and may be manufactured and operated at low cost.

The movable weather protection will keep the floors of the building free from rain and snow until the facade installation is taking place. It may at all time be located between the current top floor of the building and the floor that is under completion and creates thereby a controlled environment allowing concrete to dry and welding to be done in a controlled manner. It also gives the construction workers a much more comfortable workplace.

According to an embodiment, a gap is formed between the spaced apart first and second guiding means. The elongate uprights extend in the gap such that the guiding means are in contact with the opposing external guiding surfaces of the elongate uprights. An advantage with this configuration is that a robust weather protection arrangement which is easy to assemble is achieved. Moreover, by the particular arrangement of the guiding means of the holders and the external guiding surface on the uprights there are no auxiliary components that obstruct movement of the upright through the gap between guiding means. The elongate upright may therefore easily be moved between the guiding means, from the upper end of the upright to its lower end.

The present disclosure also relates to a building comprising a weather protection arrangement according to the present disclosure.

Further features and alternatives of weather protection arrangement of the present disclosure are disclosed in the detailed description and in the appended claims.

Detailed description of embodiments

The weather protection arrangement according to the present disclosure will now be described more fully hereinafter. The weather protection arrangement according to the present disclosure may however be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those persons skilled in the art. Same reference numbers refer to same elements throughout the description. Figure 1 shows a building 200 under construction comprising a movable weather protection arrangement 100 according to the present disclosure. The building 200 under construction is a multistory building, i.e. so called sky-scraper. A tower crane 201 is positioned on top of the building to assist the construction work. The upper floors of the building are subject to concrete work. That is, the uppermost floor is being constructed by pouring of concrete while the concrete of the underlying floors is hardening. Figure 2 is an enlarged view of the uppermost portion of the building 200 of figure 1. A weather protection arrangement 100 is arranged to cover a section of the facade of the building. In figure 2, the weather protective cover 20 is depicted transparent to not obscure underlying features. By "facade" is in the present disclosure meant the external limits of the building. That is, either completed external walls of the building or the outer limits of the floors under construction. In figure 1, the weather protection arrangement 100 is arranged outside the edges or limits of the last ten floors of the building and covers each side of the building. However, the weather protection arrangement 100 may be designed to cover a larger, or smaller, section of the facade of the building. Figure 2 also shows a vertical axis Y and a horizontal axis X. The vertical axis Y extends parallel with the facade of the building and indicates the vertical direction along the building. The horizontal axis X is orthogonal to vertical axis Y and extends parallel with the upper surface of the floor 210 and in direction away from the facade of the building.

The weather protection arrangement 100 comprises at least a first and a second elongate upright 10.1, 10.2 which are configured to extend in vertical direction along the facade of the building. Thus, in figure 2, the elongate uprights are oriented vertically along the facade of the building. The length of the elongate uprights 10.1, 10.2 depends on the vertical length requirements of the weather protective cover. That is, the number of floors that needs to be protected. However, typically the elongate uprights are configured such that each elongate upright extends between at least two floors of the building. The elongate uprights are arranged parallel and spaced a part at a predetermined distance from each other. The weather protection arrangement may, in dependency of the size of the facade, comprise any suitable number of vertically oriented elongate uprights. For example, in figure 2 the weather protection arrangement 100 comprises six elongate uprights which are arranged next to each other across the width of the facade. A weather protective cover 20 extends between the first and the second elongate upright 10.1, 10.2. The weather protective cover may be a continuous rigid or flexible sheet of rectangular shape and may extend between the upper end and lower ends of each elongate uprights. The weather protective cover is configured to be impermeable to water, i.e. rain or fog. It may also be impermeable or semi-impermeable to wind. For example the weather protective cover 20 is made of a flexible plastic material such as polyvinylchloride (PVC) or polypropylene (PP). It may also be made of a rigid material, such as polycarbonate sheets. The weather protective cover is slidable attached to the respective first and second elongate upright 10.1 , 10.2 as will be described hereinafter with reference to figure 8. The weather protection arrangement 100 may comprise several weather protective covers 20. In the weather protection arrangement illustrated in figure 2, a weather protective cover extends between adjacent elongate uprights on the facade of the building. That is, a second weather protective cover also extends between the second and the third elongate upright, a third weather protective cover extends between the third and the fourth elongate upright and so on.

The weather protection arrangement 100 further comprises at least a first and a second holder 30.1, 30.2 which each comprises guiding means (not shown) for guiding movement of a respective elongate upright 10.1 , 10.2 in vertical direction along the facade. The holders 30.1 , 30.2 are configured to be attached to a floor 210 of the building. Preferably, the holders 30.1 , 30.2 are configured to be releasable attached to the floor of the building. The advantage thereof is that it minimizes the number holders used in the weather protection arrangement since holders may be removed from completed lower floors and reattached to upper floors that are under construction.

In figure 2, the holders 30.1, 30.2 are schematically indicated but will be described more in detail hereinafter. The weather protection arrangement comprises at least one holder 30.1 , 30.2 for each vertically oriented elongate upright 10.1, 10.2. However, preferably the weather protection arrangement comprises more than one holder for each elongate upright. As indicated in figure 2, the weather protection arrangement 100 may comprise at least two holders for each elongate upright. A first set of first and second holders 30.1 30.2 are thereby attached to one floor of the building and a second set of first and second holder 30.1 30.2 are attached to another floor of the building. The precision of the vertical movement of each elongate upright, as well as the overall stability of the weather protection arrangement increases with the number of holders for each upright. Typically, the weather protection arrangement 100 may comprise several sets of holders 30.1 , 30.2 wherein one set of holders 30.1 , 30.2 is attached to each floor that the weather protection arrangement is configured to cover. It is appreciated that when the weather protection arrangement comprises further elongate uprights each set of holders comprises a corresponding number of holders. When the weather protection arrangement comprises more than one set of holders 30.1, 30.2, the sets of holders are aligned vertically such that the holders 30.1 , 30.2 etc form vertical rows on the facade. That is, the first holders 30.1 of each set of holders are oriented into a first vertical row and the second holders 30.2 of each set of holders are oriented into a second vertical row along the facade of the building.

Figure 3 shows a perspective view of a holder 30.1 of the weather protection arrangement according to the present disclosure. Figure 4 shows the holder 30.1 of figure 3 in a view from above. The holder 30.1 comprises a base 33 which is configured to be supported and attached on the floor 210 of a building. The base 33 may thereby be a flat plate. The base has a second end 32 which comprises means 34, 14 for attaching the holder 30.1 to the floor 210 of the building. The holders may thereby be attached to the upper surface of the floor or to the external vertical front of the floor. The means 34, 14 may be two openings 34 in the base 33 and two bolts 14 for attaching the holder 30.1 to the floor 210. The floor 210 may thereby comprise an elongate slot 21 1 for receiving the bolts 14 in locking engagement. The openings 34 in the base 33 may be oblong to allow axial adjustment of the holder 30.1.

The holder 30.1 further comprises a first and a second guiding means 40, 41 which are arranged at a first end 31 of the holder 30.1. The guiding means 40, 41 are spaced apart from each other such that a gap 50 is formed between the guiding means. The guiding means 40 are thereby arranged at opposite sides of horizontal axis X which extends parallel with the floor 210 and from the second end 32 of the holder to the first end 31 of the holder. Each guiding means 40, 41 are arranged at a predetermined distance from the horizontal axis X. The guiding means 40, 41 are thereby arranged spaced apart, opposite to each other in a common horizontal plane. Preferably, the holder 30.1 comprises a first and a second arm 35, 36 which extends away from the first end 31 of the holder. A first guiding means 40 is arranged at the end of the first arm 35 and a second guiding means 41 is arranged at the end of the second arm 36. The arms 35, 36 are spaced apart to provide a sufficient the gap 50 between the guiding means 40, 41 such that an elongate upright (not shown) may be received there between. The provision of arms 35, 36 further ensures that the guiding means 40, 41 extends sufficiently beyond the edge of the floor 210. In the described embodiment, the first and second guiding means 40, 41 are double sided conical rolls, i.e. the rolls that have two circumferential conical surfaces separated by a circumferential ridge and facing in opposite directions. The arms 35, 36 may therefore, as shown in figure 4 extend in an angle with respect to the longitudinal axis X. The guiding means 40, 41 may also be cylindrical rolls or guiding blocks. Guiding means in the form of rolls are rotationally attached by a shaft to the holder 30.1 or to a respective arm 35, 36 thereof. The rolls have circumferential contact surface 44 (i.e. envelope surface) which, in use, is in contacting engagement with a guiding surfaces of the upright. The rolls 40, 41 are thereby arranged such that the contact surface 44 of each roll 40, 41 is directed towards the longitudinal axis X which extends between the first and the second roll 40, 41.

The holder 30.1 further comprises a third arm 37 which extends between the first 35 and the second arm 36. The third arm 37 protrudes, parallel to axis X, in direction away from the first end 31 of the base plate 34. The end of the third arm 37 comprises a guiding element 43 in the form of a guiding block having a sliding surface for contacting an elongate upright extending through the gap 50. The end of the third arm 37 may further comprise two lateral engagement elements 38 which are configured to engage two corresponding flanges of an elongate upright extending through the gap 50 (elongate upright not shown in figure 3 and 4). The lateral engagement means 38 extends orthogonal to longitudinal axis X in a common horizontal plane. Figure 5 shows the holder 30.1 of figure 3 and an elongate upright 10.1 extending through the gap 50 between the first and second guiding means 40, 41. It is appreciated that the elongate upright 10.1 of figure 5 may comprise further features, such as extensions or sliding elements for the protective weather cover as will be described in figure 7. However, to enhance the comprehension these features are omitted in figure 5.

The elongate upright 10.1 is of uniform cross-section throughout its length and comprises opposing first and second guiding surfaces 11, 12 which may be flat, i.e. plane surfaces. The first and the second guiding surfaces 11, 12 are external guiding surfaces. Thus, the first and the second guiding surfaces are located on the outside of the elongate upright, and faces in opposite direction away from the respective upright 10.1. That is, the opposing guiding surfaces faces in opposite direction with regards to the longitudinal extension of the elongate upright 10.1. Seen in cross-section of the upright 10.1 the opposing gliding surfaces 11, 12 extend parallel to each other in a common horizontal plane. The elongate upright 10.1 may further comprise a third external guiding surface 13 which may be flat and that extends between the first and the second guiding surfaces. The elongate upright 10.1 further comprises two engagement flanges 39 which extends in direction towards each other and parallel with the third guiding surface 13 such that a space is formed between the each engagement flange 39 and the third guiding surface 13. Each external guiding surface 11, 12 further comprise a guide flange 16 which extends orthogonally away from the respective guiding surfaces 11, 12.

Figure 6 is a view from above of the holder 30.1 and the elongate upright 10.1 of figure 5. In operation, the elongate upright 10.1 is received in the gap 50 between the first and the second guiding means 40, 41. The first and the second guide surfaces 11, 12 of the elongate upright 10.1 thereby faces in opposite directions away from the longitudinal axis X. In figure 6 the first and the second guide surfaces 11, 12 faces respectively orthogonally away from the longitudinal axis X. The first guiding means 40 is thereby in contact with the first external guiding surface 11 of the elongate upright 10.1 and the second guiding means 41 is in contact with the second external guiding surface 12 of the elongate upright 10.1. That is, the circumferential contact surfaces 44 of the first and the second guiding means 40, 41, which are rolls, are in contact with a respective one of the first and second guiding surface 11, 12 of the upright 10.1. The elongate upright 10.1 may thereby be displaced in a guided vertical movement along the facade of the building. In addition, the sliding surface on the end of the third arm 38 of the holder 30.1 is in contact with the third external guiding surface 13 of the elongate upright 10.1 and the two lateral engagement elements 38 are positioned in the space between the engagement flanges 39 and the third guiding surface 13 of the elongate upright 10.1. The elongate upright 10.1 is thereby secured from detaching from the holder 30.1 and may only move in vertical direction on the facade of the building. Moreover, each conical roll may be guided by a respective guide flange 16 of the elongate upright 10.1 such that the circumferential surface of the roll is in firm contact the respective guiding surface 11, 12. The first circumferential conical surface of each guide roll is thereby in contact with a respective guide flange 16 and the second circumferential conical surface of each guide roll is in contact with a respective guiding surface 11, 12. The elongate upright 10.1 is, as a consequence thereof, firmly secured from any movement other than in vertical direction.

In detail, figure 6 shows that the first elongate upright 10.1 may be a profile and has a hollow cross-section and comprises a first side wall 17.1 which is directed towards the facade of the building and a second side wall 17.2 which is directed away from the facade of building. The first upright 10.1 further comprises a third and a fourth side wall 17.3, which extends between the first and the second side walls 17.1, 17.2 and that are respectively directed parallel with the facade of the building. The third side wall 17. 3 comprises, i.e. constitute, the first guiding surface 11 and the fourth side wall 17.4 comprises, i.e. constitute, the second guiding surface 12. The first and the second guiding surface are thereby also directed parallel with the facade of the building.

Figure 7 shows a side view of a section of a first elongate upright 10.1 of the present disclosure. Also shown is a holder 30.1. The upright 10.1 is in engagement with a respective guiding means 40, 41 of the holder. The first elongate upright 10.1 further comprises a first extension 23 and second extension 24 which are arranged in direction away from the elongate upright 10.1 and away from the holder 30.1. A weather cover 20 is attached to the first extension 23. The weather cover 20 and the first extension 23 may thereby comprise sliding members 21, 22 for slidable attaching the weather cover 20 to the elongate upright 10.1. The second extension 24, which is arranged between the elongate upright 10.1 and the first extension 23 and may be a lattice work which has the purpose of positioning the weather protective cover 20 at a distance beyond the facade of the building. The weather protective cover 20 comprises first and second sliding members 21 which extend along the opposing longitudinal edges of the rectangular weather protective cover 20. The first elongate upright 1.1 also comprise first and second sliding members 22 which extend longitudinally along the respective elongate upright. It is appreciated that while figure 7 shows a first elongate upright 10.1, all elongate uprights may comprise sliding members 21 for engagement with the weather cover 20. Therefore, when in the text below reference is made to the "first elongate upright 10.1" reference is also made to other elongate uprights, such as the "second elongate upright 10.2" In the embodiment of figure 7 the first and second sliding members 22 of the upright 1.1 are arranged on the first extension 30. However, the sliding members 22 of the elongate upright may also be arranged on the second extension 23 or on the elongate upright 10.1.

The sliding members 22 of the upright 10.1 and the sliding members of the weather cover 20 will be described in the following with reference to Figure 8 which shows an enlarged view of the first extension 23 and the weather cover 20 of figure 7.

The sliding members 22 of the first elongate upright 10.1 protrude away from the first extension 23 of the elongate upright 1.1, i.e. orthogonally to a longitudinal centre axis of each elongate upright. The sliding members 21 of the weather protective cover 20 and the sliding members 22 of the extension 23 of the elongate upright 10.1. are configured to engage each other such that the sliding member 22 of the weather protective cover 20 and the sliding member 21 of the elongate upright 10.1 are locked into each other and movable axially relative each other in vertical direction. That is, the sliding member 21 of the weather protective cover 20 is movable relative the sliding member 22 of the elongate upright 10.1 in longitudinal direction of the elongate uprights. Correspondingly, the sliding members 22 of the elongate upright 10.1 are movable relative the sliding members 21 of the weather cover in longitudinal direction along opposite edges of the weather protective cover 20. In the embodiment shown in figure 8, the sliding members 22 of the first elongate upright 10.1 are, in cross-section, elongate elements with outwards directed protrusions. The sliding member 21 of the weather protective cover is in cross-section an open rectangle with inwardly pointing protrusions. In operation the sliding member of the protective cover 20 is slid over the sliding member 22 of the first elongate upright 1.1 whereby the sliding member 22 of the elongate upright 10.1 extends out from the open end of the sliding member 22 of the weather cover 20 and the protrusions of sliding member 21 and 22 mutually lock each other.

It is appreciated that each elongate upright may be constituted by separate pieces that are held together by clamps or bolts and that the elongate uprights are manufactured in one single piece, e.g. by extrusion or by welding. It is further appreciated that the respective elongate upright may be designed without extensions 23, 24. The sliding members 22 of each elongate upright may then be a portion of the elongate upright 10.1. It is also appreciated that the design of the sliding members 21 of the weather cover and the sliding members 22 of the respective elongate upright may vary within the scope of the present disclosure. For example the elongate uprights may have sliding members of rectangular cross-section with a slot for the weather protective cover. The sliding member 21 of the weather protective cover may be of circular cross-section and slidable received within the sliding member of the elongate upright.

The function of the weather protection arrangement for a building will in the following be described with reference to figure 9. Figure 9 shows schematically a first elongate upright 10.1, a second elongate upright 10.2 and third elongate upright 10.3. Each elongate upright is oriented vertically and comprises at least one sliding member 22, which extends longitudinal along the upright. A weather protective cover 20 extends between each elongate upright. The weather protective cover comprises opposing sliding members 21 which are arranged on opposing longitudinal edges of the weather protective cover 20. The sliding members 22 of the upright 10 are slidable received in a respective sliding member 21 of the weather cover 20. At least one blocking element 25 may be arranged on each upright 10.1, 10.2 and configured to block the weather protective cover 20 and/or its sliding member 21 from moving in downwards vertical direction. The blocking member 25 may be a rectangular block. The blocking member 25 may be arranged at a lower end of the upright such that it is positioned under the lower end of the sliding member 22 of each elongate upright. However, the blocking member 25 may also be arranged on the weather protective cover and configured to prevent downwards sliding of the weather cover by engagement with the elongate upright (not shown) The holders 20 and the guide elements 40, 41 have been omitted for clarity.

To move the weather protection arrangement to a second floor, the first elongate upright 1.1 is moved upwards, guided by the guide elements on the facade of the building (see figure 1). The blocking element 25 on the first elongate upright 10.1 blocks the lower end of the first sliding member 21 of the weather protective cover 20. The weather protective cover 20 is therefore raised together with the first elongate upright 10.1 and simultaneously the second sliding member 21 of the weather protective cover 20 slides upwards in engagement with the first sliding member 22 of the second elongate upright 10.2. In a next step, the second elongate upright 10.2 is raised on the facade of the building, during this movement the first sliding member 22 of the second elongate upright 10.2 slides relative the second sliding member 21 of the protective weather cover 20. Simultaneously, the second protective weather cover 20 follows the second elongate upright 10.1 upwards whereby the first sliding member 21 of the second weather protective cover 20 is blocked by the blocking element 25 on the second elongate upright 10.2 and the second sliding member 21 of the second weather protective cover 20 slides in engagement with the first sliding member 22 of the third elongate upright 10.3. The weather protective arrangement 1 is thereby moved upwards on the facade of the building by raising the elongate uprights 10.1 - 10.3 one after another.

It is appreciated that when the facade is narrow and only comprises few elongate uprights it may for practical reasons be suitable to raise more than one elongate upright simultaneously. For example, when the weather protection arrangement comprises two elongate uprights these may be raised simultaneously. In that case the sliding members on the weather cover and on the elongate uprights may be omitted and the weather cover may be attached directly to the respective elongate uprights.

Each elongate upright 10.1, 10.2 may comprise a stop device 60 which is arranged to abut against a holder 30.1 30.2 of the weather protection arrangement 1 in order to prevent the upright from moving vertically in direction downwards on the facade of the building. In normal operation the uprights are intended to move in upwards vertical direction on the facade of the building. Figure 10a shows perspective view of a longitudinal cross-sectional view of an elongate upright 10.1 having a stop device 60. Figure 10b shows a side view of the elongate upright 10.1 and stop device 60 of figure 10a. The stop device 60 may be an elongate rectangular piece and comprise a first end 61 which is pivotally attached to the elongate upright 10.1 by a pivot pin. The second end 62 of the stop device 60 is configured to abut against an upper surface of a holder 30.1. The stop device 60 further comprise a spring means 64, such as a blade spring which biases the stop device 60 towards the third guiding surface 13 of the elongate upright 10.1. The third guiding surface 13 of the elongate upright 10.1 is provided with a longitudinal slot (not shown) which allows the stop device 60 to swing out of the elongate upright 10.1 such that the second end 62 may abut on the upper surface of the holder 30.1. To enable the stop device to pass the holder as the elongate upright is moved upwards the first end 61 of the stop device is chamfered. This has the advantage that the stop device 60, by contact with the holder, may be forced into the elongate upright 10.1 against the force of the spring 64. When the stop device has cleared the holder the spring forces the stop device to swing out and block the elongate upright from returning downwards. In the embodiment shown in figure 10a, the first end 61 of the stop device 60 is an upper end of the stop device and the second end 62 of the stop device 60 is a lower end of the stop device.
