Definitions
- the invention relates to a cover arrangement for a channel arrangement, according to the preamble of claim 1.
- Channels in particular drainage channels with covers, are known in which the cover is placed on a support surface of the frame and held there by screws, bolts or the like. To clean the channels or similar work in the channels, the cover must first be lifted up and set down at another location. This is extremely energy-intensive and also time-consuming.
- a major disadvantage of this known arrangement is on the one hand in the cost-intensive manufacture and assembly and on the other hand in the time-consuming loosening and fastening of the screws.
- hinges are provided, the wings of which are connected to the frame and the cover, and via which the cover can be folded on one side.
- a major disadvantage of this known channel device is that the cover is permanently connected to the frame. The cover cannot be removed.
- Another disadvantage of using hinges is that hinges are very maintenance-dependent. In particular when using a duct to drain surfaces, contamination and corrosion inevitably occur, which lead to malfunctions and violent breaks in the hinge area.
- the hinges should be arranged in such a way that the cover can be tilted in the direction of the gradient.
- the tilt angle of the cover is reduced by the angle of the slope. This results in an angle of the cover with respect to the horizontal, which favors an uncontrolled closing of the cover, for example due to gusts of wind or vibrations.
- an uncontrolled closing of the cover poses a great risk of injury.
- the invention is therefore based on the object of developing a cover arrangement such that the safety of the arrangement is increased in a simple manner when used.
- a basic idea of the invention is that the cover can be pivoted to two sides without tools by means of two hinge units arranged opposite one another, consisting of two rotating and fastening devices.
- the cover of a permanently installed channel arrangement can thus be pivoted to the side desired by the user.
- the hinge units are preferably designed such that the cover can be lifted vertically upward from the frame without tilting movement relative to the frame, the fastening devices or hinge units disengaging. In addition to tilting or swiveling, you also have the option of completely lifting off the cover.
- the turning and fastening device - in analogy to a conventional hinge - comprises a swivel element and a swivel pin.
- the swivel element is firmly connected to the cover and bent downward, hook-shaped.
- the pivot pin is fixed to the frame and shaped corresponding to the pivot element, so that
- Swivel element is rotatable about the pivot pin.
- the pivot pin is arranged in relation to the axis of rotation in such a way that the pivot element can be lifted off the pivot pin when the cover is in the fully fitted state.
- the hook-shaped swivel element of all hinge units simultaneously come out of engagement with the swivel pin.
- the rotating and fastening device preferably each comprise a guide bar which is firmly connected to the frame.
- the pivot pin is arranged such that the hook-shaped pivot element is positively guided between the pivot pin and the guide bar during the pivoting movement of the cover.
- the rotating and fastening device is preferably designed in such a way that, at a predetermined swivel angle, a support surface of a cover foot is lifted off a support surface of the frame.
- the guide bar and the pin are designed and arranged such that a downwardly bent end of the swivel element comes into contact with the surface of the guide bar during the swivel movement carried out by lifting the cover on the side opposite the element at a first swivel angle of preferably 10-20 occurs.
- a limiting device for limiting the swivel angle is provided within the cover arrangement.
- the limiting device comprises the hook-shaped pivot element and the pivot pin.
- the swivel element is designed such that the downwardly bent end of the element abuts the underside of the swivel pin at a predetermined limiting angle of the swiveled cover, thus interrupting a further swiveling movement.
- the limiting device comprises the hook-shaped pivot element and the frame edge.
- the swivel element is designed such that the surface of the swivel element abuts against the inner surface of the frame edge when the limit angle is reached, thus interrupting a further swiveling movement.
- the surface of the hook-shaped swivel element is flush with the surface of the cover, so that when the limit angle is reached, the surfaces of the swivel element and the cover abut the inner surface of the frame edge.
- the pivot element is designed such that to limit the pivot angle at a limit angle, the downwardly bent end of the pivot element abuts the underside of the pivot pin and at the same time the surface of the pivot element abuts the inner surface of the frame edge or the surfaces of the pivot element and the cover against the Butt the inner surface of the frame edge.
- the delimitation angle is determined in such a way that the cover always assumes the original rest position without the application of force.
- the cover can only be tilted to the extent that maintenance or cleaning work on the duct arrangement or cable laying can be carried out.
- An advantage of this embodiment is that the channel arrangement does not accidentally remain open in the tilt position.
- a cover arrangement of this embodiment is particularly preferably installed in areas with high public traffic, but in particular also in schools or kindergartens. This minimizes the risk of injury, especially for children playing on an unsupervised channel arrangement.
- the delimitation angle is chosen to be less than 90 °.
- the limiting angle is determined in such a way that the tilted cover maintains its position without the use of force.
- An advantage of this embodiment lies in the fact that the cover is tilted to the limit angle for carrying out work within the channel arrangement and then remains open without being held fast. This allows sewer works to be done quickly and be carried out inexpensively.
- the delimitation angle should be greater than 90 °. In order to avoid that the cover is closed in an uncontrolled manner, for example by gusts of wind or vibrations, the angle should preferably be 95-110 °.
- the region of the hook-shaped swivel element which is bent downward is designed essentially in the form of a circular arc, the center of a full circle completing the circular arc being identical to the axis of rotation when the cover is in the fully fitted state. This minimizes the effort required to tilt the cover and at the same time ensures a uniform rotary movement in the area of the hinge units.
- the downwardly bent end of the swivel element is preferably rounded off in such a way that the swiveling movement of the cover takes place completely continuously, without sinking and without a horizontal displacement of the cover.
- the pivot pin is preferably designed in such a way that an outwardly pointing end is essentially semicircular and the center of a full circle completing the semicircle is identical to the axis of rotation.
- the pivoting element and the pivot pin take up the largest possible common area during the pivoting movement, as a result of which a continuous pivoting of the cover is maximized without sinking and without a horizontal displacement of the cover.
- a horizontally running section of the pivot pin preferably runs parallel to a horizontally running region of the hook-shaped swivel element.
- the hook-shaped swivel element and the swivel pin are spaced apart from one another when the cover is in the fully fitted state, preferably in the range of 1-5 mm. So rest in the completely put on Condition of the cover only the cover feet on the support surface of the frame.
- the forces acting on the bearing surface are thus absorbed directly by the frame.
- the rotating and fastening devices are thus arranged in such a way that they only have to absorb the forces acting on the weight of the tilted cover when the cover is tilted, thereby achieving high material savings. Due to this design, the cover arrangement can be produced very inexpensively.
- the frame and the cover can be of rectangular design, the pivot pins being arranged on the end face to the axis of rotation, being attached directly to the frame and / or being spaced apart from the frame edge by supporting elements which are fastened to the frame.
- the frame and cover are circular in shape, the pivot pins being mounted at a distance from the frame edge by means of support elements which are fastened to the frame.
- the surface of the hook-shaped swivel element is guided on an inner surface of an outer edge of the frame when the swivel movement is carried out. Due to the rounded surface of the swivel element, this is “rolled off” on the inner surface when the cover is pivoted.
- a major advantage of this embodiment is that the cover is prevented from moving horizontally when the cover is tilted.
- the bearing surface is preferably provided with a groove for introducing a damping element, as a result of which the passability of the cover is significantly improved.
- the damping element prevents the cover from rattling, which can be caused by unevenness in the contact surface or by dirt particles that have penetrated.
- the frame, the guide bolts and the pivot pins are formed in one piece, preferably from cast iron (eg cast iron).
- the cover and the pivoting element are also in one piece and are preferably formed from cast iron.
- Engagement openings for inserting a tool are provided in the cover. This tool is used to lift and tilt the cover at the desired location.
