Abstract

The scaffolding tower assembly, primarily for use in areas with restricted access such as corridors, stairways etc., comprises first and second pairs of spaced uprights 1,2 that define first and second ends of the assembly and which are connected by a number of braces 3,5. A ladder section 6<SB>1</SB> is mounted between one pair of uprights and can be moved between an upright, closed, operational position and an open position in which it affords personal access to the interior of the tower. The ladder section is preferably mounted on the tower assembly through a hinge 9 at its upper end that connects it to an upper horizontal brace member so that a limited degree of vertical movement is allowed. The lower end of the ladder section may include open yokes 10 that engage a lower brace member when the ladder is in an operational position but allow the ladder to be rotated to an open position when the ladder is lifted. The tower may include a number of ladder sections and one or more platforms 12 within the tower with a trapdoor 14 to facilitate movement within the interior. The tower may also include adjustable feet 16 to facilitate its use on stairs.

Description

23730 1 7
TOWER ASSEMBLY
The invention relates to tower assemblies such as scaffolding-type towers which are used by personnel in various industries such as the building and 5 decorating industries.
In certain circumstances, tower assemblies are used in quite restricted spaces such as passageways or stairways. In these circumstances, personnel access to the interior;of the tower assembly may be limited.
The present invention provides a tower assembly in which a ladder section is movably mounted to provide personnel access to the inside of the tower assembly. 15 The present invention provides a tower assembly comprising: a first pair of spaced uprights defining a front end of the tower assembly and a second pair of spaced uprights defining the rear end of the tower assembly; a plurality of braces extending between the uprights; and a ladder section movably mounted between the first pair of spaced uprights between an upright closed operational position 20 and an open position in which it affords personnel access to the interior of the tower assembly.
- 2 An embodiment of the invention is described below with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a tower assembly mounted on a stairway; Figure 2 is an enlarged view of part of the tower assembly showing a 5 ladder section in the open position; Figure 3 is an enlarged view of an upper part of a ladder section; Figure 4 is an enlarged view of a lower part of a ladder section; and Figure 5 is an enlarged view showing the end part of a brace.
10 The drawings show a scaffolding-type tower assembly mounted on a stairway. The assembly comprises a first pair of spaced uprights 1 defining a front end of the tower assembly and a second pair of spaced uprights 2 defining the rear end of the tower assembly. The uprights 1, 2 may each be formed of one or more lengths of steel or aluminium tubing and are connected together by a 1 S plurality of short horizontal braces 3, long horizontal braces 4 and inclined braces S. A first ladder section 6 is movably mounted between the uprights 1. The ladder section is formed of a pair of upright stiles 7 connected by a plurality of 20 horizontal bars 8 forming the steps of the ladder section.
The ladder section 6 is pivotally connected at its upper end to an upper
short brace 3 through a hinge formed by a pair of inverted U-shaped straps 9 welded to the upper ends of the stiles 7 as shown in Figure 3. The ladder section 6 is connected to a lower short brace 3 through a pair of downwardly open yokes l O welded to the lower ends of the stiles 7 as shown in Figure 4. The straps 9 are 5 sufficiently long to allow vertical movement of the ladder so that the yokes 10 can be lifted clear of the lower brace 3 to enable the ladder section to swing about the hinge from the upright closed operational position shown in Figure 1 to the open position shown in Figure 2 in which it affords personnel access through the uprights 1 to the interior of the tower assembly.
The tower assembly shown in the drawings is adapted for use on a stairway and to this end the front uprights 1 may be longer than the rear uprights 2. Alternatively, the front and rear uprights can be the same length but when installed on a staircase the top of the rear uprights will be higher than the top of IS the front uprights. The assembly has first and second horizontal platforms 12, 13 mounted thereon and the movable ladder section 6 affords personnel access to the interior ofthe tower assembly beneath the first platform 12. Further movable ladder sections 62 and 63 are provided to give personnel access to the interior of the tower above the lower platform 12. Each platform 12, 13 is formed with a 20 trapdoor 14 affording personnel access to the interior of the tower assembly above the platform from below.
The horizontal bars 8 of the ladder sections extend outwardly of the stiles 7 and can provide supports for braces 4 and 5. One bar 8 in each ladder section carries a latching clamp 15 at each end for latching the ladder section to an adjacent upright.
s Each of the uprights 1, 2 is provided with an adjustable foot 16 for levelling the tower assembly.

Claims (1)

1. A tower assembly comprising: a first pair of spaced uprights defining a front end of the tower assembly 5 and a second pair of spaced uprights defining the rear end of the tower assembly; a plurality of braces extending between the uprights; and a ladder section movably mounted between the first pair of spaced uprights between an upright closed operational position and an open position in which it affords personnel access to the interior of the tower assembly.
2. A tower assembly as claimed in Claim 1, wherein the ladder section is
mounted on the tower assembly through a hinge at its upper end pivotally connecting it to an upper horizontal brace extending between the first pair of uprights and through a pair of downwardly open yokes at its lower end connecting 15 it to a lower horizontal brace extending between the first pair of uprights; the hinge allowing limited vertical movement of the ladder section so that the yokes can be lifted clear of the lower brace to enable the ladder section to swing about the hinge into the open position.
20 3. A tower assembly as claimed in Claim 1 or Claim 2, wherein a plurality of movably mounted ladder sections are provided.
- 6 4. A tower assembly as claimed in any preceding claim, further comprising a first horizontal platform mounted within the tower assembly; wherein a movable ladder section affords access to the interior of the tower beneath the platform.
5 5. A tower assembly as claimed in Claim 4, wherein a second horizontal platform is mounted within the tower assembly above the first platfonn and wherein at least one movable ladder section affords access to the interior of the assembly above the first platform.
10 6. A tower assembly as claimed in Claim 4 or Claim 5, wherein the or each platform is formed with a trapdoor affording personnel access to the interior of the tower assembly above the platform from below.
7. A tower assembly as claimed in any preceding claim, wherein the or each 15 ladder section is formed of a pair or upright stiles connected by a plurality of horizontal bars forming the steps of the ladder section and wherein at least one of the horizontal bars extends outwardly of the stiles and carries a latching clamp for latching the ladder section to an adjacent upright.
20 8. A tower assembly as claimed in any preceding claim, adapted for use in a stairway, wherein the first pair of uprights are longer than the second pair of uprights.
9. A tower assembly as claimed in any preceding claim, wherein each of the uprights is provided with an adjustable foot for levelling the tower assembly.
10. A tower assembly substantially as described herein with reference to the 5 accompanying drawings.
