ABSTRACT:
FIELD OF INVENTION
This invention relates to components for roof assemblies. More particularly, but not exclusively, the invention relates to components for roof assemblies for conservatories and greenhouses.
BACKGROUND OF INVENTION
The construction of conservatories requires the beams and rafters to be of sufficient strength but also to be sufficiently lightweight. Many designs of profiles for conservatories require considerable amounts of material to provide the required strength and rigidity. This creates cost and weight disadvantages.
In addition, many known conservatories require a large number of components in order to be able to construct the configurations and sizes of conservatories that may be desired.
SUMMARY OF INVENTION
According to one aspect of this invention there is provided a glazing bar comprising a main support member and a cap engaging member on an edge region of the main support member, the cap engaging member comprising a detent portion extending from said edge region towards an opposite edge region of the main support member to engage a selected one of a plurality of corresponding detents on a cap to be engaged by the cap engaging member.
Preferably, the cap engaging member includes two of said detent portions, each extending on opposite sides of the main support member toward said opposite edge thereof.
The main support member may be formed from two elements secured together wherein the cap engaging member is in the form of folded back portions at the edge region of each element.
A second cap engaging member may extend outwardly from said opposite edge region of the main support member and may comprise an upstanding member extending toward the first cap engaging member. In one embodiment the second cap engaging member may further include a curved portion extending inwardly from the upstanding member. The curved portion may be adapted to engage a part of a second cap, whereby the curved portion is so curved such that said part of the second cap extends in use substantially tangentially to the curved portion.
The glazing bar is preferably formed of a steel material, or other suitable material, for example aluminium.
Preferably, the second cap engaging member extends from the support member in substantially opposite directions, and the cap engaging member comprises two of said upstanding members and a curved portion on each upstanding member.
The second cap engaging member may include at least one outwardly extending strip, preferably first and second outwardly extending strips, the or each strip extending from the main support member, and desirably, in the case of first and second outwardly extending strips, in opposite directions to each other. The or each of said outwardly extending strips preferably includes a raised portion so shaped that a fastening member, for example a bolt, may extend through said raised portion such that a part of the fastening member, for example a head of the bolt, engages the raised portion, generally or approximately tangentially therewith.
Preferably, the, or each, detent portion on the first cap engaging member is adapted to co-operate with a selected detent formation on said first cap, whereby the position of the first cap on the glazing bar may be adjusted. Each of said detent formations may be provided with a plurality of inwardly extending triangular detents arranged one after the other on said first cap. Preferably, the respective triangular detents closest to the further cap have a width which is less than the width of succeeding triangular formations further away from said further cap. Preferably, each detent formation include three of said triangular detents.
According to another aspect of this invention there is provided a beam member for a roof arrangement, the beam member comprising a main support member and a rafter support member extending outwardly from the main support member, wherein securing means is provided on the rafter support member at an edge region of the rafter support member, the securing means comprising upstanding means extending from the rafter support member and adapted to cooperate with a part of a securing member of a rafter assembly.
In a first embodiment, the upstanding means may comprise a first upstanding member extending from the rafter support member and a second member extending from the first member back toward the rafter support member.
In this embodiment the second member extends inwardly of the rafter support member. The upstanding means may define a recess to receive a cooperating part of a securing member of a rafter assembly, the recess allowing said cooperating part to move to accommodate a desired position of the rafter assembly.
The beam member is preferably formed of a steel material or other suitable material for example aluminium.
The securing means preferably includes pivot receiving means which may comprise a curved member, for receiving a pivot on the securing member, whereby the securing means allows the rafter to pivot to said desired position about the pivot receiving means.
Preferably, the securing means includes a stop member to prevent movement of the co-operating part therebeyond. The securing means may include a holding region, whereby the co-operating part of the rafter is held between the recess and the holding portion.
Preferably, the rafter support member extends outwardly in opposite directions from the main support member. Each of said rafter support members may comprise securing means as described above.
The, or each, rafter support member as described above may be provided along one edge region of the main support member. A further rafter support member may be provided along the opposite edge region of the main support member. The further rafter support member may comprise a securing means having the features as described above. In the preferred embodiment, the second rafter support member may extend on opposite sides of said main support member, and each may comprise a securing means at the free edge region on each side. Each securing means may be as described above. Preferably, the, or each securing means is adapted to engage on an outward surface thereof of the holding member for a cap to be secured to the beam member.
In a second embodiment, the upstanding means comprises a step extending outwardly of the rafter support member and adapted to cooperate with a detent on a securing member of a rafter assembly. Preferably the upstanding means comprises a first upstanding member extending from the rafter support member and a second member extending from the first member back toward the rafter support member outwardly of the rafter support member to provide said step.
The rafter support member may comprise means for holding a cap engaging member. Preferably the rafter support member is shaped to provide a re-entrant aperture to hold a cap engaging member. Preferably two of said rafter support members are provided on opposite sides of the main support member and, together, the rafter support members may be so shaped to define the aperture.
According to another aspect of this invention there is provided a roof assembly comprising a beam member as described above and a rafter assembly, wherein the rafter assembly comprises a rafter and a securing member on the rafter to secure the rafter assembly to the beam member, the securing member including a co-operating part which can cooperate with the securing means on the beam member to secure the rafter assembly to the beam member.
In one embodiment, the co-operating part on the securing member of the rafter assembly can be received in the recess in the securing means of the first embodiment to secure the rafter assembly to the beam member. The cooperating part may be in the form of a limb member having one end region receivable in the pivot receiving means, and may also include another end region which can engage the stop member, thereby being prevented from moving beyond it.
The rafter assembly may further include a glazing bar, which may be as described above, the glazing bar having capping means on one end th
