[0001] The invention related to a fall guard for a roof, provided with a number of clamping constructions which are to be clamped on the roof gutter and consists of an upper clamping member and a lower clamping member, at least one of which clamping members is adjusted in the vertical direction, and an upright connected to each clamping construction for attaching restraining means, both clamping members of each clamping construction being fitted to a bracket which is intended to engage around the roof gutter in such a way that the clamping members grip on the bottom of the gutter.
[0002] A fall guard of this type is disclosed in EP-A-0338142 (figure 4) designated for DE, FR, GB, IT and NL and published after the filing date of the present EP-A-0417355.
[0003] In every day practice of laying and repairing roofs there is a need for a fall guard which is easy and quick to fit and dismantle and which restrains the people working on the roof should they be in danger of falling from the roof.
[0004] From BE-A-885504 a fall guard for a roof is known provided with a number of clamping constructions which are to be clamped on the roof gutter and consist of an upper clamping member and a lower clamping member, at least one of which clamping members is adjustable in the vertical direction, and an upright connected to each clamping construction for attaching restraining means. It is true that this known construction can be fitted and dismantled rapidly, but it leaves something to be desired with regard to the required ruggedness. The upper clamping member of each clamping construction consists of a hook which engages over a raised edge of the roof gutter and the lower clamping member is constructed in the form of a clamping arm which is adjustable along the upright and can be clamped by means of a bolt with a butterfly nut. Under heavy load, for example because a person falls against the restraining means at fairly high speed, there is a risk that the raised gutter edge will tear away. Moreover, this construction is suitable only for a specific shape of roof gutter (with a vertical raised edge).
[0006] The object of the present invention is to improve the stability of the fall guard and therefore a supporting leg is connected at its top end to the bracket in a hinged manner and its lower end can be made to grip on the wall beneath the roof gutter, while an intermediate leg is connected in a hinged manner both to the supporting leg and to a spacer attached to the bracket.
[0007] The invention will now be explained with the aid of the figures, in which an illustrative embodiment is drawn.
[0010] The balustrade shown comprises girders 1 which are attached or coupled to two uprights 2. Each upright is attached at 3 to a bracket 4. This bracket 4 connects two clamping members 5 and 6 and extends around a roof gutter 7 of a sloping roof 8. This roof rests via a wall plate 9 on a wall 10. The upper clamping member 5 is not adjustable but, on the other hand, the lower clamping member is provided with a screwed spindle 6a which is screwed into a screwed bush 6b firmly connected to the bracket 4.
[0011] At 11, the bracket 4 has a hinged connection to a supporting leg 12, the lower end of which is supported against the wall 10 via a hinged foot 13. The screwed bush 6a is also connected to a horizontal spacer 14, which is supported against the wall 10. This spacer 14 is connected via two hinged couplings 15, 16 and an intermediate leg 17 to the supporting leg 12. In certain cases the spacer 14 can be omitted.
[0012] It will be clear that the clamping constructions described can be brought into the desired position quickly and easily by moving the clamping construction over the outer edge of the roof gutter 7, starting from the position of the screwed spindle 6b, there being sufficient gap between this spindle and the clamping member 5. The screwed spindle can then be screwed into its bush in such a way that the clamping position shown is produced. After positioning of the clamping constructions, uprights 2 and girders 1 are fitted. Various modifications are possible within the framework of the invention.
