Definitions
- the invention relates to a manhole cover which comprises a frame anchored in the floor with a lower-lying support shoulder which at least partially surrounds the frame opening, and a grate or cover resting thereon and sealingly closing the frame opening.
- the object of the invention is to provide a generic manhole cover with a fuse, which allows the easiest possible assembly and disassembly of the grate or cover.
- the invention creates a manhole cover in which the grate or cover is automatically secured when it is put on, without an additional operation being necessary. Disassembly is similarly simple, and the manhole cover can easily be designed in such a way that the grate or lid can only be removed quickly and easily using a special tool.
- La is a plan view of a first manhole cover according to the invention.
- Fig. Lb cut a perspective view of the manhole cover according to Fig. La,
- FIG. 3 is a perspective view of a second manhole cover according to the invention.
- the shaft cover shown in FIGS. 1 a, 1 b has a frame 1 with a two-part lower-lying support shoulder 2, on which a grate 3 rests.
- two diametrically opposed securing parts 4a, b are attached to the frame. They are preferably made in one piece from spring steel and attached to the frame 1.
- the securing part 4a grips on both sides via shoulders 5a, b, so that a snap connection is created which secures it to the frame 1.
- the securing part 4a comprises a holding part 6, which is designed as an elastic tab extending obliquely from bottom to top and to which a locking part 7 adjoins.
- the grate 3 has a recess 8 on its surface, the bottom of which is formed by a locking surface 9. The locking part 7 and the locking surface 9 are in engagement with one another and thus secure the grate 3.
- the second securing part 4b is preferably of the same design as the first locking part 4a, but it can also be replaced by another device, e.g. B. by a nose on the frame, which engages in a recess on the surface of the grate (further options see below).
- Metallic materials in particular spring steel and other types of steel or cast iron with spheroidal graphite, as well as corrosion-resistant plastics are particularly suitable as materials for securing parts.
- the manhole cover is unlocked in that the locking part 7 is withdrawn from the locking surface 9 with elastic deformation of the holding part 6.
- the grate 3 can then be easily lifted off.
- the placement of the grate is made easier by the fact that it is slightly beveled at the bottom. As soon as it has reached the locking position, the lock snaps into place by itself.
- FIG. 3 shows a manhole cover according to the invention, in which a cover 3 'can be positively fitted into the frame 1 - with projections 10 on the frame 1 engaging in recesses 11 on the cover 3' - that a single securing part 4 is sufficient.
- the latter is flanked by projections 10 and is therefore particularly protected.
- cover 4 shows a manhole cover according to the invention, likewise with only one securing part 4, which is designed in the same way as the manhole covers already described.
- the edge of the cover 3 ' is beveled diametrically opposite the securing part 4 and projects under a correspondingly beveled overhanging edge portion of the frame 1, so that the cover 3' is also locked there.
- 5a-f show various possibilities for designing securing parts 4 and their anchoring on the frame 1.
- the securing part 4 is particularly easy to attach and remove, since the shoulders of the above-described embodiments are missing. Due to the projecting edge 12, over which the securing part 4 extends, the same is nevertheless sufficiently secured.
- the unlocking is facilitated compared to the above-described embodiments because of the greater length of the holding part 6 with the same cross section. 5d, e have the advantage that the securing part 4 can be attached to the frame 1 from above, i. H. it can be easily retrofitted and replaced more easily.
- the securing part 4 is cast into the frame 1.
- the locking part 7 presses - as indicated by an arrow - with a residual tension against the locking surface 9, which is inclined towards the edge of the recess 8 for easier unlocking.
- the lid 3 * is pressed against the frame 1.
- FIG. 7 shows a variant of the embodiment according to FIG. 6 a, b with the securing part 4, which is pushed over a shoulder 5.
- FIG. 8 shows a manhole cover according to the invention, in which the recess 8 on the side of the cover 3 ' attached and is capped.
- access to the security part 4 without special tools is difficult and particularly effective protection against theft is provided.
- Fig. 9 shows an embodiment in which the securing part 4 is cast into the grate 3 and its holding part 6 is designed as an elastic tab running obliquely from top to bottom.
- the locking part 7 is in engagement with a locking surface 9 in a recess 8 on the underside of the frame 1.
- FIG. 10 shows a variant of the embodiment according to FIG. 9, in which the securing part 4 is plugged onto the grate 3 and locked by means of a snap lock.
- the securing part 4 can be removed very easily after dismantling the grate 3.
