Definitions

  • the invention relates to a device for locking a grating on a frame, in particular on a drainage channel, with at least first and second locking means, of which one locking means is provided on the grating and the other locking means on the frame, and with at least one locking element for locking of the grating on the frame with the first and second Locking means cooperates and can be moved between an unlocking position in which the cover grate is unlocked from the frame and a locking position in which the cover grate is locked to the frame.
  • Such locking devices are known in various forms and in use.
  • the known locking devices have various disadvantages. Some of them have a very complex construction, which leads to high manufacturing costs.
  • those known locking devices such as US-A-1,898,871, which are distinguished by a comparatively simple construction
  • US-A-1,898,871 which are distinguished by a comparatively simple construction
  • a secure locking of the grating on the frame cannot be guaranteed over a longer period of time due to different signs of wear.
  • this is particularly important for a drainage channel that is covered by a cover grate.
  • the cover grids must sit securely and firmly on the drainage channel and be fastened so that pedestrians and traffic are not endangered. Particularly when the drainage channel is installed in a street, the grating is exposed to very high loads when vehicles are run over.
  • the locking device ensures a permanent and secure attachment of the cover grate to the drainage channel despite these loads.
  • some known locking devices for locking and unlocking the grating on the frame are difficult and cumbersome to handle, which then leads to problems in operation on site.
  • the present invention is based on the object of developing a device of the type mentioned at the outset in such a way that that it has a simple construction, is easy to handle and ensures a secure locking of the grating on the frame for a longer period of time.
  • the locking device according to the invention is characterized by a simple construction, whereby the manufacturing costs can be kept low.
  • the device according to the invention can be handled easily.
  • the locking element loosely seated in the recess of the first locking means only needs to be pushed into the locking position. This can expediently be carried out with the aid of a suitable tool, such as eg a screwdriver.
  • a suitable tool such as eg a screwdriver.
  • Another advantage of this arrangement is that the locking element in its unlocked position cannot be lost even after the cover grille has been removed from the frame, since it is held in the recess of the first locking means. This further simplifies the handling of the locking device according to the invention.
  • the arrangement of at least one locking means according to the invention maintains the proper functioning of the locking device even over a long period of time without restrictions, since the locking means ensures that the locking element remains in its locking position, in particular even when the cover grating is subjected to greater loads (e.g. from vehicles driving over it) .
  • the first locking means can optionally be provided on the cover grille or frame and accordingly the second locking means on the frame or cover grate.
  • the cutout of the first locking means preferably has first and second opposite inner surfaces, which in the area of the locking position of the locking element run essentially parallel and at a distance from one another.
  • the distance between the first and second inner surfaces can correspond to the thickness of the section of the locking element inserted into the recess, as a result of which the locking element in its locking position comes into loose contact with both inner surfaces.
  • the distance can also be such that the locking element in its locking position in comes into firm contact with both inner surfaces, the locking element possibly having spring properties such that it can be compressed between the two inner surfaces, as a result of which the locking element is braced in the recess in its locking position.
  • both inner surfaces should expediently run essentially horizontally in the area of the locking position.
  • the distance between the two inner surfaces of the recess can increase in the area of the unlocking position of the locking element, so that there is greater freedom of movement there, which enables the locking element to be easily moved from the unlocking position into the locking position.
  • at least one inner surface in the area of the unlocking position of the locking element can have a section inclined with respect to the horizontal.
  • the recess in the first locking means can expediently have an opening in the region of the unlocking position of the locking element.
  • the second locking means should have a contact surface against which the locking element can be brought into contact in its locking position.
  • This contact surface can be essentially parallel to the first The inner surface of the recess of the first locking means and in particular essentially runs horizontally, as a result of which the locking element in its locking position comes into a safe intermediate position between the two locking means.
  • the contact surface runs slightly inclined with respect to the first inner surface of the recess, as a result of which the locking element can be clamped between the first inner surface of the recess of the first locking means and the contact surface of the second locking means during its movement into the locking position, which contributes in particular to a rattle-free locking of the grating on the frame.
  • the second locking means has a stop surface which is arranged essentially transversely to the direction of displacement of the locking element and which forms a stop for the locking element and prevents further movement of the locking element beyond its locking position.
  • the locking element is thus essentially locked in its locking position between the locking means on the one hand and the stop surface on the other hand.
  • the second locking means can also have a means which moves the locking element already inserted into the recess of the first locking means into the unlocking position while the covering grate is placed on the frame.
  • This means is preferably formed from a guide surface that is inclined with respect to the direction of movement of the locking element and that with the locking element in FIG touching system. In this embodiment, it is always ensured that the locking element is in the unlocked position after the grating has been placed on the frame and before locking, provided that it has already been inserted into the recess of the first locking means. Malfunctions are thus avoided and the handling of the locking device is facilitated.
  • the locking means is designed as a projection protruding into the movement path of the locking element.
  • the projection can be designed so that the locking element rests in its locking position on the projection, which then serves as a stop for the locking element located in the locking position.
  • a particularly firm locking of the locking element in its locking position can be achieved in that it can be braced by the locking means against the first and / or second locking means, which also contributes to an essentially rattle-free attachment of the cover grate to the frame.
  • the locking element consists of an essentially straight rod.
  • the rod can have spring properties, as a result of which the rod-shaped locking element can be moved more easily past the locking means into its locking position by being bent a little, and which is advantageous if the locking element is to be tensioned in its locking position.
  • a currently particularly preferred embodiment is characterized in that the first locking means is formed by an inwardly projecting part of the side wall of a drainage channel and the second locking means is provided on the underside of the associated cover grate.
  • the first inner surface of the recess can be arranged above the second inner surface and the second inner surface can run horizontally, the second locking means can be designed as a downwardly projecting hook-shaped projection and its contact surface when the cover grate is placed on the drainage channel essentially in the plane of the second inner surface of the recess lie and thus reach under the locking element in its locking position.
  • the contact surface preferably slopes upwards in the direction of the locking position of the locking element if the locking element is to come into a clamping contact between this contact surface and the first inner surface of the recess.
  • the guide surface which moves the locking element already inserted into the recess of the first locking means into the unlocking position while the covering grate is placed on the drainage channel, can expediently be formed on the underside of the hook-shaped projection and inclined upwards in the direction of the unlocking position of the locking element run.
  • the locking means should also be formed on the underside of the grating.
  • the second locking means is on a transverse web extending over the entire width of the cover grate educated.
  • the distance of the locking means designed as a projection to the transverse web should correspond to the thickness of the locking element, as a result of which a relatively motion-free seat of the locking element is ensured in its locking position.
  • the locking means can preferably be provided on a longitudinal bar of the grating.
  • a first locking means is present on each of the two longitudinal side walls of the drainage channel, in the recess of which one end of the locking element is inserted. The locking element is thus held at both ends by a first locking means.
  • the locking device described below is used to lock a cover grate on a drainage channel. Nevertheless, other possible uses are also conceivable in which a cover grate is to be locked to a frame.
  • a drainage channel 2 which has two parallel, spaced-apart, vertical side walls 3, 4 and a base 5 and is open at the top, is covered by a removable cover grating 6.
  • the drainage channel 2 is installed in the ground, in a street or other traffic area so that the upper edge of its side walls 3, 4 and the grating 6 are substantially flush with the surface of the floor, the street or other traffic area.
  • the cover grate 6 has two outer longitudinal webs 8, which are arranged adjacent to the upper edge of the side walls 3, 4 when the cover grate 6 is placed on the drainage channel 2, and further inner longitudinal webs 10, 11, 12 and 13.
  • the longitudinal webs 8 to 13 run in the longitudinal direction of the drainage channel 2 and parallel to each other at a distance from each other.
  • the cover grate 6 rests on grate support surfaces 14 formed on the inner sides of the side walls 3, 4 of the drainage channel 2, as can be seen in FIGS. 3 to 5.
  • the cover grate 6 is provided with cross bars, of which the cross bars 15 to 18 are shown in the figures.
  • the crossbars are attached to the underside of the longitudinal webs 8 to 13 and extend at right angles to the longitudinal webs 8 to 13 over the entire width of the covering grate, that is to say from one outer longitudinal web 8 to the other outer longitudinal web 9, the transverse webs running parallel to one another at intervals.
  • the locking section 20 contains a cutout 22 which has a lower horizontal surface 24 and an upper surface spaced apart therefrom, which divides into a horizontal surface section 26 and an adjoining obliquely upwardly inclined surface section 28 is.
  • the two surface sections 26, 28 are each approximately half as long as the lower surface 24.
  • the recess 22 is delimited at the top by a bracket 30, on the underside of which the surface sections 26 and 28 are formed.
  • the outer longitudinal webs 8, 9 of the grating 6 are interrupted in the region of the bracket 30 of the locking sections 20, and these interrupted sections are each filled by a bracket 30 when the grating is placed on the drainage channel 2.
  • the bracket 30 itself is part of the upper edge section of the associated side wall 3 or 4 of the drainage channel 2, as can be seen in particular from FIGS. 1 and 2.
  • a locking rod 32 is provided, which is inserted with its two ends into the cutouts 22 of the locking sections 20 lying in pairs, as shown in FIGS. 1 and 2.
  • the locking rod 32 is inserted through the opening 29 into the recess 22.
  • the upwardly inclined surface section 28 of the recess 22 thereby facilitates the insertion of the locking rod 32 into the recess 22.
  • the locking rod 32 has a square or rectangular cross section and lies with one surface of its end on the lower horizontal surface 24 of the recess 22 loosely and can be pushed back and forth along this surface 24 between an unlocked position and a locked position.
  • the locking rod 32 lies below the upwardly inclined surface section 28, as indicated by dashed lines in FIG. 3 (that is, according to FIGS. 3 and 4 in the right half of the recess 22).
  • the locking rod 32 according to FIGS. 3 and 4 is shifted to the left and is now below the upper horizontal surface section 26.
  • the locking rod is 32 always shown in its locked position.
  • the distance of the upper horizontal surface section 26 to the lower horizontal surface 24 depends on the height of the locking bar 32 and is dimensioned such that the locking bar 32 lying on the lower horizontal surface 24 just comes into loose contact with the upper horizontal surface section 26.
  • this distance can also be dimensioned such that the locking rod can come to a fixed intermediate position between the lower horizontal surface 24 and the upper horizontal surface section 26, in which case the locking rod should preferably have spring properties such that it at least accordingly is compressed a little, whereby it is clamped in its locking position in the recess 22.
  • the length of the lower horizontal surface 24 of the recess 22 corresponds to at least twice the thickness of the locking bar 32 in the horizontal direction.
  • the lower horizontal surface 24 is arranged lower relative to the grate support surface 14 and thus forms a depression.
  • the locking device further comprises a hook-shaped locking projection 34, which is provided on the lower portion of the crossbar 16 of the grating 6.
  • a locking projection 34 is arranged at the two ends of the crossbar 16, in such a way that each locking projection 34 lies with the cover grating 6 placed on the drainage channel 2 adjacent to the locking section 20 in the associated side wall 3 or 4 of the drainage channel 2 (see Figure 2).
  • the recess 22 of the locking section 20 is essentially delimited on both sides by the two transverse webs 16 and 17 when the cover grate 6 rests on the drainage channel 2.
  • the transverse web 16 with the locking projection 34 delimits that section of the cutout 22 in which the locking rod 32 is in its locked position (according to FIG. 4 on the left side of the cutout 22).
  • the hook-shaped locking projection 34 is provided with an upper bearing surface 36 which engages under the locking rod 32 in its locking position.
  • the depth of the support surface 36 which forms an "abutment" in the locking position of the locking rod 32 and thus prevents removal of the cover grate 6, corresponds at most to the width of the locking rod 32 in the horizontal direction.
  • the support surface 36 is essentially in alignment with the lower horizontal surface 24 of the recess 22 when the cover grate rests on the drainage channel 2. However, the support surface 36 is slightly inclined with respect to the plane formed by the lower horizontal surface 24 of the recess 22, in such a way that the support surface 36 rises slightly towards the crosspiece 16.
  • the distance between the support surface 36 and the plane spanned by the upper horizontal surface section 26 of the recess 22 decreases in the direction from the free end 37 of the locking projection 34 to the crossbar 16.

  • a further movement of the locking rod 32 is then no longer possible. In any case, however, a further movement of the locking rod 32 is prevented by the facing vertical surface 38 of the crossbar 16, which may serve as a stop surface for the locking rod 32.
  • the underside of the locking projection 34 has an inclined guide surface 40 which rises towards the free end 37. If the locking bar 32 is already inserted into the recess 22 before the grating 6 is placed on the drainage channel 2, this guide surface 40 has the effect that the locking bar 32 is always in its unlocked position after the covering grating has been placed on the drainage channel 2. If the locking rod 32 is in its locking position (ie according to FIGS.
  • a locking projection 42 is provided on the underside of the two central longitudinal webs 11, 12 (cf. Figures 1 and 5).

  • the distance between the first surface 43 and the crossbar 16 corresponds at least approximately to the thickness of the locking bar 32 in the horizontal direction.
  • the locking rod 32 When the cover grate 6 is placed on the drainage channel 2, the locking rod 32, which is already in its unlocking position at this point in time, comes into contact with the locking projections 42 and is bent downwards by them (see the dashed illustration in FIG. 5).

If the locking rod 32 has reached its locking position, its vertical deflection is also canceled again.
  • the locking projections 42 now prevent the locking rod 32 from moving out of its locking position as a result of movements of the cover grating 6, as can occur, for example, when vehicles drive over them.
