Ridge tile hook

Abstract: A ridge tile hook by means of which ridge tiles are positioned relative to each other and can be fixed on a ridge board comprises a strip (1) for placing on a ridge tile, which strip has an elongated slit (5) to allow through a screw or nail (8), a first stop (2) disposed at one side of the strip (1), for an end edge of the abovementioned ridge tile, and a second stop (3) disposed at the opposite side of the strip (1), for an end edge of the next ridge tile. According to the invention, a sliding piece (6) is clamped in the abovementioned slit (5), through which sliding piece the screw or nail (8), which is an integral part and constitutes the only fixing element of the ridge tile hook, projects. The sliding piece (6) with fixing means (8) is slid so far in the slit (5) that the fixing means (8) can be pushed through a hole in the ridge tile concerned and screwed into the ridge board.

Description: The invention relates to a ridge tile hook, comprising: a strip for placing on a ridge tile, which strip has an elongated slit in which a screw or nail is mounted, a first stop disposed at one side of the strip, for an end edge of the abovementioned ridge tile, and a second stop disposed at the opposite side of the strip, for an end edge of the next ridge tile. Known ridge tile hooks of this type are fixed by means of three nails. One of the nails is hammered through the slit into a hole in the ridge tile concerned and into the ridge board on which the ridge tiles are resting; the other two nails are hammered into the ridge board through holes in a second strip of the ridge tile hook which connects to the abovementioned first stop and lies on the ridge board. These ridge tile hooks are therefore fixed by three fixing means. The hooks themselves are consequently relatively expensive and take too long to fit. The object of the invention is to overcome these disadvantages, and to this end the ridge tile hook mentioned in the preamble is characterized in that a sliding piece is clamped in the abovementioned slit, through which sliding piece the screw or nail, which is an integral part and constitutes the only fixing element of the ridge tile hook, projects. The hook is fixed by only one fixing means. Said means is preferably a screw which is inserted by means of an electric screwdriver. A nail, which may be a twisted nail, is also possible. The hook is cheaper and lighter. In order to prevent the sliding piece from being pressed out of the slit, it is preferable for the sliding piece to be provided at the top side with a ring which engages on the abovementioned strip. It is usual to make the second stop run through a bend of 90°. In order also to be able to place the fixing means of the hook under the end of the bent second stop, said stop is provided with a notch. It is pointed out that US-A-2279943 discloses a wavy clip for a cladding element for the wall of a building. The clip consists of a strip and a hook-shaped part into which the bottom edge of a wall cladding element fits. The strip is provided with an elongated slit through which a screw or nail can be fitted. A washer is placed in such a way between the head of the screw or nail and the cladding element that when the screw is screwed or the nail is hammered into the cladding element the head of the screw or nail brings the edges of the washer into engagement with the boundary edges of the slit. There is no question of a sliding piece which is clamped in the slit when the screw is not screwed in or the nail not hammered in. When the clip is not fitted the screw or nail can fall out of the slit, and it does not form an integral part of the clip. Nor is there a stop at the edge of the clip opposite the hook-shaped part. The clip cannot be used as a ridge tile hook. US-A-4314433 discloses a roof tile hook for fixing roof tiles, comprising: a strip with a hook-shaped end and an elongated slit for passing through a screw or nail. The slit does not have clamped therein a sliding piece through which the screw or nail projects in such a way that it forms an integral part of the roof tile. Nor does the strip have a stop at the end lying opposite the hook-shaped end. The invention also relates to a ridge tile. In order to make overlapping ridge tiles connect to each other without gaps, and thus to achieve a better seal, it is preferable for said ridge tile to be provided with a recess near an end edge at the bottom side and top side, for the accommodation of the strip of a ridge tile hook for fixing an overlapping ridge tile. The invention will now be explained in greater detail with reference to the figures. Figure 1 shows a perspective view of a ridge tile hook according to the invention. Figure 2 shows a perspective view of a part of a roof ridge. Figure 3 shows a section through the top part of a sloping roof. The ridge tile hook shown comprises a strip 1, having at one end a downward running stop edge 2 and at the other end an upward running stop 3 in the form of a flange bent through 90°, which flange has a notch 4 in the end edge. The strip 1 has cut out of it an elongated slit 5, in which a plastic sliding piece 6 with passage openings is clamped in such a way that it can be slid in the slit 5. The ring 7 is integral with the sliding piece and lies on the top surface of the strip 1, so that the sliding piece 6 cannot be pushed or driven out of the slit. A screw 8 projects with its end through the openings of the sliding piece 6 and the ring 7. The ridge tile hook is laid at one end of a ridge tile 10a resting on a ridge board 9 until the stop edge 2 goes into engagement with the end edge of said ridge tile. A hole is left open in the end part of said ridge tile. The screw is positioned in line with the hole in the ridge tile. The screw is then pressed or hammered through said hole and screwed into the wooden ridge board. The sliding piece 6 can be pushed up so far that the screw 8 projects through the notch 4 of the second stop 3. It is possible to slide the ridge tile hook to the right before the screw has been fully tightened, with the result that the overlap can be made smaller. If lines and figures are placed on the ridge tile, this overlap can be read on the ridge tile, which makes the device easier to use. When it engages on the end edge of the ridge tile, the stop edge 2 prevents the ridge tile hook from turning when the screw 8 is being tightened. A subsequent ridge tile 10b is laid on the fixed ridge tile 10a in such a way that an end edge thereof engages on the stop 3. The strip 1, the screw 8 and the stop edge 2 are then sealed off. The ridge tile is provided with a recess at the bottom side and top side, for the accommodation of a strip 1 on the top surface of a ridge tile lying beneath in the overlapping region, and a recess is provided in one side edge of each ridge tile, for the accommodation of a part of the stop 3 of a ridge tile hook which is fitted on a tile beneath in the overlapping region. The section shown in Figure 3 shows roof boards 11a, 11b, the top tile battens 12a, 12b, the top tiles 13a, 13b and the screens 14a, 14b. The latter screens serve to prevent birds and vermin from being able to enter the space below the ridge tiles. The ridge board bracket, in which the ridge board 9 is positioned, is indicated by 15. The main advantage of the invention is that a ridge tile can be fixed extremely easily using only one fixing means. The ridge tile hook is also lighter and cheaper than known ridge tile hooks.
