Description
Title
A Roofing Seat Device
Field of the Invention
The invention relates to a roofing seat device suitable for mounting to two roof battens for lateral
movement along the battens.
Background to the Invention
Roof construction generally involves affixing s to a base (building shell) to define an
inverted V-shape structure above the base. The rafters are covered with felt or other waterproof
material. Across the felt are affixed a series of cross battens perpendicular to the rafters. The
battens are lly parallel to the top edge of the inverted e structure. To provide a
further waterproofing layer, a series of overlapping slates are laid or fixed to the battens.
Slating roofs can be a difficult task for workers as they are someway from the ground and need
to feel secure as they work. ularly, a worker or user in such a situation will be required to
frequently move his or her position, so as to collect slates, lay the slates on wooden battens and
move onto the next portion of the roof that he or she is working on.
By necessity, a great deal of movement is required of the workers as they collect and lay slates
on the wooden s. lly, most workers will sit on the battens, having one leg resting on
a batten while the other leg is tucked up underneath the person acting to anchor the worker in
place. The positioning of the legs is both uncomfortable and cumbersome. Also, the workers
must move their tools and/or slates as they themselves move across the battens when Slating the
roof. All the while, the worker must take great care and effort not to damage the felt layer.
In on, many different roofs have ent pitches, for example one roof may be at an angle
of 45 degrees to the vertical, whereas a second roof may be at an angle of 20 degrees to the
vertical.
Attempts have been made to address the above~mentioned problems. For example, United
Kingdom patent application GB 2229482 discloses a roofing seat device e of engaging
with roof battens for rolling movement across a slanted roof during construction or Slating of the
second batten
roof, the device comprising a support base having first batten engagement means,
engagement means, and a seat disposed at an angle with t to the support base for
supporting a person during use, wherein the first and second batten engagement means se
rollers d to roll along a batten, and wherein the spacing between the first and second batten
engagement means can be adjusted. In this , both of the batten engagement means are
adjustable with respect to the support, thereby allowing adjustment of the device to fit to roofs
with battens having different spacing and to allow the seat in a horizontal disposition on
roofs of different pitches. However, referring to Fig. 1, it will be seen that when a person is
located on the seat of the , most of the weight will be loaded axially onto the length
adjustable bar which causes wear and tear, and tely breakage, of the adjustment
mechanism of the adjustable bar. Further, adjustment of the device to enable it to be mounted on
roofs having different s requires adjustment of the batten engagement means, even if the
batten spacing on the roofs is the same.
EP 0042465 and German y Model No. 8705770 both disclose a carriage le for
engagement with and rolling movement along two roof battens or roof mounted. However, the
carriages disclosed in both applications are not adjustable so that they cannot be used on roofs
with battens having different spacing. Furthermore, the support surface is able for use as a
seat for a person. US Patent Publication No. 2008/0309033 discloses a seat for a person on a
roof that can only be d on the roof ridge and not on inclined roof sides.
It is an object of the present invention to overcome at least one of the above-mentioned
problems.
Statements of Invention
In a first aspect, there is provided a roofing seat device capable of engaging with roof battens for
rolling movement across a slanted roof during construction or slating of the roof, the device
comprising a support base having first batten engagement means, second batten engagement
batten
means, and a surface for supporting a person during use, wherein the first and second
engagement means comprise rollers adapted to roll along a batten/rail, wherein the first and
second batten/rail engagement means comprise rollers adapted to roll along a batten/rail, wherein
the first batten/rail engagement means comprises two spaced apart pairs of rollers each pair
comprising a first roller which is adapted to engage a top of a first batten/rail and a second roller
which is d to engage an upper side of the first batten/rail, and the second batten
ment means comprises two spaced apart rollers each roller adapted to engage a top of a
second batten/rail; characterised in that the surface for supporting the person is a seat which is
adapted for ment of the angle of the seat with respect to the t base.
Unlike the s of EP 0042465 and DE 8705770, the device of the present in vention includes
a seat for a person that is adjustable with respect to the support. This allows the device be used
on roofs of different pitches while maintaining the seat in a generally ntal orientation. .
While the device of the invention has been described as being suitable for engagement with roof
s, it will be appreciated that it is equally suitable for engagement with other types of rails
that are disposed laterally on a roof, and in this regard the invention is not restricted to devices
that are only suitable for use with roof battens.
Typically, the support base comprises a first part having the first batten engagement means and
the seat, and a second part having the second batten engagement means, and wherein the first and
second parts are connected for movement together and apart. Preferably, the first and second
parts of the roof are telescopically connected, and typically include a locking means to lock the
first and second parts together in a desired position. Ideally, the first batten ment means is
adapted for engagement of a lower batten (Le. a batten that is located on the roof at a lower
position to the other batten) and the second batten engagement means is adapted for engagement
of an upper batten.
Preferably, the first batten ment means comprises a pair of rollers including a first roller
disposed to engage to a top of a batten and a second roller adapted to engage an upper side of the
batten. The term “upper side” should be understood to mean that side of the batten that is
uppermost ~ in the case of a lower batten, the upper side is the side facing the upper batten. In a
preferred embodiment of the invention, the first batten engagement means comprises two pair of
rollers, typically spaced apart on opposite sides of the device.
Suitably, the second batten engagement means ses a roller disposed to engage a top of a
batten. Ideally, the second batten engagement means comprises two, ideally spaced apart, rollers,
each disposed to engage a top of the batten. The rollers may be elongated along an axis of
rotation.
In a preferred ment of the invention, the seat is hingedly mounted to the support base for
adjustable tilting movement of the seat into a plurality of different positions. This allows the
angle of the seat to be adjusted independently of the adjustment of the batten engagement means.
Various means are envisaged for providing a seat which is ably mounted to the support. In
the example provided below, the seat is hingedly connected at one end to the support base, and
an te end has a support strut adapted to support the seat at a plurality of different angles to
the support base.
Suitably, the device of the invention comprises a stabiliser arm which extends laterally of the
device (i.e. down the roof) and is adapted to bear against the roof when the device tilts away
from the roof. Thus, when a user of the device shifts their weight towards a rear of the seat, this
can cause the device to tilt and lift-off the roof. The stabiliser arm helps prevent this occurrence,
and stabilises the device by g against the roof and preventing tilting of the device away
from the roof. The stabiliser arm ly comprises a roller mounted on an end of the arm for
rolling movement along the roof. In this regard, the arm may be disposed with respect to the roof
such that it is in constant engagement with the roof, such that as soon as the device begins to tilt
away from the roof, the arm (or more particularly the roller at the end of the arm) will bear
against the roof preventing further tilting.
In one embodiment of the invention, the first or second batten engagement means ses a
safety brake means which is disposed with respect to the rollers such that when a roller passes
beyond an end of a batten the brake engages the batten to stop further movement of the device
with respect to the batten. This has the effect of preventing the device rolling off a roof.
Typically, the brake is disposed on the first batten ment means, between the pairs of
rollers and adjacent to one of the pairs. Ideally, the first batten engagement means comprises two
, one disposed adjacent to each pair of rollers. Due to its position adjacent a roller pair, as
soon as the roller pair run off the batten, the device will fall a little bringing the brake into
contact with the batten. The brake itself may take many forms, the details of which will be
nt to a person skilled in the field. In the embodiment bed below, the brake ses
a serrated edge which is disposed on the first batten engagement means such that it is spaced
from the batten when the roller pairs engage the batten, but is brought into contact with the
batten when the rollers roll of an end of the batten.
The device may also include a locking anchor d for locking the roofing seat device in
on, the locking anchor comprising an arm which is adjustable into and out of engagement
with the roof to securely anchor the device to the roof. The purpose of this anchor is to prevent
unwanted movement of the device along the roof when it has been manoeuvred into a desired
position, and also prevent the device sliding or falling off the roof when in use. The anchor may
take many forms; in the embodiment described below, the anchor comprises a leg which can be
articulated into engagement with the roof, thereby preventing further movement of the device
along the roof. The user may also weak a harness of the like which can be ed to the device
during use such that when the device is securely anchored, the user is securely anchored to the
roof via the .
In a second , there is provided a carriage adapted for carrying slates along a roof and
suitable for engagement with, and rolling movement along, battens of a roof or roof-mounted
rails and comprising a support base having first batten engagement means, second batten
engagement means, and a surface suitable for supporting a person, a plurality of slates or the
like, wherein the first and second batten engagement means comprise rollers adapted to roll
along a batten, wherein the first batten engagement means comprises two spaced apart pairs of
rollers, each pair comprising a first roller which is adapted to engage a top of a first batten and a
second roller which is adapted to engage an upper side of the first batten, and the second batten
engagement means comprises two spaced apart rollers each roller adapted to engage a top of a
second batten/rail; characterized in that the first batten ment means is adapted for
engagement with a lower batten, and the second batten engagement means is adapted for
engagement with an upper batten. This ensures that the majority of the weight of the device and
its load is directed to the batten ment means having two batten-engaging rollers.
Typically, the support surface is ed adjacent to the first batten engagement means.
Suitably, the rollers (57) of the second /rail engagement means se rollers that are
elongated along an axis of rotation. ably, the first or second batten/rail engagement means
comprises a safety brake means which is disposed with respect to the s such that when a
roller passes beyond an end of a batten/rail the brake engages the batten/rail to stop further
movement of the device with respect to the batten/rail. In this specification, the term “batten”
refers to the elongated structural wooden beams employed in the uction of a roof.
However, the carriage of the invention may likewise be suitable for engagement with other types
of rails mounted laterally across a roof. In this regard, the term “batten engagement means”
should be understood to include within its meaning batten or rail engaging means.
Typically, the brake is disposed on the first batten ment means, in which the first batten
engagement means comprises a pair of first and second s, and wherein the brake is disposed
on the device between the pairs of rollers and nt to one of the pairs. Ideally, the first batten
engagement means ses two brakes, one disposed adjacent to each pair of rollers.
In one ment of the invention, where the carriage is adapted for carrying tiles along a roof,
the support base may take the form of a hod.
In a third aspect, the invention es a lateral support track suitable for mounting to a roof
between two roof ladders and supporting a roofing seat device and a carriage adapted for
carrying slates along a roof for lateral rolling movement along the support track, the support
track comprising a pair of ted, spaced apart, rails, and means for adjustably mounting
each end of the support track to a roof ladder.
Suitably, the spaced apart rails are connected by means of a lattice truss, although other means of
supporting the two rails in a spaced—apart, parallel, disposition are envisaged and will be known
to those skilled in the art.
Typically, the means for adjustably mounting each end of the t track to a roof ladder
comprises a hook means, which hook means is ideally capable of lateral movement along the
support track.
The carriage of the invention may also include a separate clamp comprising one or more rollers
and which is adapted for sliding movement along a rail of the lateral support track and for
reversible engagement with the second batten ment means such that when the clamp and
batten engagement means are engaged the adapter provides anchorage of the ge to the
track. The clamp is suitably adapted for engagement with the second batten engagement means
such that the at least one roller bears against an outside of the rail (i.e. the side of the rail facing
the invention provides a clamp comprising one or
away from the track). Thus, in a further ,

Detailed Description of the Drawings
Referring to the drawing, and initially to Figs 1A to 1D in particular, there is illustrated a roofing
seat device of the invention, indicated generally by the reference numeral 1, and comprising a
support base 2, first batten ment means 3 fixed to the t base 2, second batten
engagement means 4 adapted for movement with respect to the support base 3, and a seat 5
disposed at an angle with t to the support base 2 for supporting a person during use, the
seat 5 being adjustable to vary the angle between the seat and the support base.
In more detail, the support base 2 comprises a first part 7 having the first batten engagement
means 3 and the adjustable seat 5, and a second part 8 having the second batten engagement
means 4. The first 7 and second 8 parts of the device 1 are telescopically connected, and include
a locking means 9 which can be actuated to lock the two parts together in a plurality of different
positions (corresponding to different batten spacings).
In this embodiment, the first batten engagement means 3 is adapted for engagement of a lower
batten (not shown) and the second batten engagement means 4 is adapted for ment of an
upper batten (not shown).
In more , the first batten engagement means 3 comprises two pairs of s, each pair
including a first roller 12 disposed to engage to a top of a batten and a second roller 13 adapted
to engage an upper side of the batten. As is evident from the Fig. 1D, the first and second rollers
are ed in a perpendicular arrangement. The rollers 12, 13 are supported on a supporting
bracket 15 having a generally L-shaped cross section, which in turn is connected to two cylinders
, 21 forming part ofthe support base 2.
The second batten engagement means 4 comprises two spaced-apart rollers 17, each disposed to
engage a top of the upper batten. The s 17 are supported on an L-shaped supporting t
18, which is connected to two cylinders 23, 24 which in turn are telescopically mounted to the
two cylinders 20, 21 forming part of the support base 2.
The seat 5 is hingedly connected at one end to the support base 2, and an opposite end has a
support strut 25 adapted to support the seat 5 at a plurality of different angles to the support base
2 by engagement of one of a plurality of different seating positions 26. The seat includes a layer
of elastomeric material 30 which in use provide grip for the user and helps prevent a user g
off the seat unintentionally.
The device also es a table 31 having a plurality of separate tments 32 suitable for
holding tools such as a , nails and the like. The table 31 may be mounted to the two
cylinders 20, 21 or the L-shaped supporting bracket 18 on the second part 8 of the device. In the
instance where the table 31 is mounted to the L-shaped supporting bracket 18, the table 31
moves in conjunction with the second part 8 of the device when the second part 8 is being
extended or retracted telescopically to engage with a batten.
A stabiliser arm 35 is provided on the device to help prevent the device tilting backwards off a
roof. The arm 35 extends lly of the device (i.e. down the root) and is adapted to bear
t the roof when the device 1 tilts away from the roof. The stabiliser arm 35 comprises a
roller 36 mounted on an end of the arm for rolling movement along the roof. In this regard, the
arm may be ed with respect to the roof such that it is constant engagement with the roof,
such that as soon as the device begins to tilt away from the roof, the arm (or more particularly the
roller at the end of the arm) will bear against the roof preventing further tilting.
The first batten engagement means 3 includes two safety brakes mounted to the L-shaped bracket
between the roller pairs. Each brake comprises a serrated bracket 37 which is positioned on
the bracket such that when the roller pairs engage the batten the serrated bracket is spaced from
the batten, and when the roller pairs roll off an end of the batten the device drops a little bringing
the ed bracket 37 into contact with the batten, whereupon the serrations engage the batten
and anchor the device in position preventing any further lateral movement until the bracket is
aged from the batten and the rollers replaced on the batten.
The device 1 also include a locking anchor 40 d for locking the device 1 in position. The
locking anchor 40 ses a leg 41 which is adjustable into and out of engagement with the
roof. The purpose of this anchor is to prevent unwanted movement of the device along the roof
when it has been manoeuvred into a desired position, and also to securely anchor the device to
the roof and prevent it sliding or falling off the roof when it is in use. In this regard, the user may
secure lves to the device such that when it is anchored in position, the user is effectively
anchored to the roof.
In use, the device of the invention may be employed by a roofer to help move about a roof when
slating the roof. The device is first adjusted to suit the pitch of the roof and the spacing between
the battens. First, the first batten engagement means is placed into engagement with a lower
batten, and then the second batten engagement means is ed until the rollers are disposed
over the top of the second batten. The seat is then adjusted until is it generally horizontal. The
device is then positioned in a place where the user wishes to start the slating process, it is locked
in place using the brake 40, and the user may then start slating. The device may then be moved
ys along the battens to allow the user apply slates across the roof.
Referring to Figs 2A and 28, there is illustrated a carriage according to a second aspect of the
invention, in which parts previously described with reference to the first aspect of the ion
are assigned the same reference numerals. The carriage, which like the roofing seat device of the
first aspect of the invention, is suitable for engagement with, and rolling movement along, roof
battens, is indicated generally by the reference l 50 and comprises a support base 52
having first batten engagement means 3, second batten ment means 4, and a surface 55
suitable for supporting a plurality of tiles or the like and a t rail 56 for supporting tiles that
are stacked on the surface 55. . In this embodiment, the second batten engagement means 4
comprises a pair of elongated rollers 57 adapted to engage a top of the upper batten. The use of
elongated rollers facilitates use of the carriage with roof battens of different spacing as the use of
elongated rollers es the requirement to adjust the batten engagement means.
Referring to Figs 3 to 7, there is illustrated a lateral t track according to a third aspect of
the invention, and indicated generally by the reference numeral 60, in which parts previously
described with reference to the first aspect of the invention are assigned the same reference
numerals. The lateral support tract 60 comprises a pair of spaced—apart rails 61 that are connected
and supported by means of truss e 62. A pair of ladder-engaging hooks 63 are mounted on
the track 60 for lateral movement along the track. In use, the track 60 is mounted by means of the
two hooks 63 to a pair of spaced apart roof ladders 65 which will generally be mounted at
opposite ends of a roof. The vertical positioning of the track 60 can be changed by simply
unhooking the track and moving to a higher rung of the two roof s 65. The rails 61 act as a
track for mounting a roofing seat device, for example a roofing seat device of the invention 1.
The roofing seat device 1 is the same as that described with reference to Figure l with the
exception that it includes a clamp 66 which is adapted for reversible ment with the first
batten engagement means 3 to help clamp the device 1 to the rail 61. The clamp 66 comprises an
ed support 68 having two rollers 69 (shown in Fig. 7). In Fig. 3 the track 60 is shown with
a roof seating device of the invention 1 mounted thereon for lateral movement along the track. In
Figs. 4 and 5, the track 60 is shown with a roofing seat device of the invention 1, and a slate-
carrying carriage of the invention 50, mounted thereon for lateral movement along the track. Fig.
6 shows a rear perspective of the roofing seat device 1 and ge 50 of Figs 4 and 5, showing
the clamps 66 attached to the second batten engagement means 3 by means of fixing means, for
example locking nuts 67. Fig. 7 shows the clamps 66 separated from the roofing seat device 1
and carriage 50. In use the clamps 66 are moved in the direction of the arrows A to engage with
the device 1 and carriage 50, whereupon ning of the g nuts results in the clamp
bearing against the top rail 61 to clamp the device 1, or carriage 50, to the track. Generally, the
clamp or clamps 66 will remain attached to the support track.
The invention is not limited to the embodiment hereinbefore described which may be varied in
construction and detail without departing from the spirit of the invention.
