DESCRIPTION

Registration Provision

The invention relates to a provision for registering a garden irrigation system.

In garden irrigation systems it is customary to lay firmly installed ducts on the ground, usually plastic pipes, and house functional units, such as connection points in log housings, which are buried in the ground. Such functional units may contain, for example, valves or water intakes.

To access the connection points arranged in the registration housing, normally a registration opening pointing upwards can be closed by a cover, which can be pivoted with respect to a rotating joint, to free the registration opening. The registration cover is in contact along an edge curve with the registration housing and is normally also supported through this edge curve vertically in the registration housing. The registration cover is made with stability, which allows a person to step on the registration cover without destroying the registration cover. Normally, stiffening ribs may be provided here on the side of the registration cover pointing down.

The usual registration arrangements show different vulnerabilities to damage, for example by sucking a closed cap not locked when passing over with a lawnmower or damaging an open registration cap that protrudes upwards during connection of a hose to a water outlet arranged in the register.

A registration provision is known from the publication for German patent application information DE 25 17 999 A1, in which the registration cover is lifted from the register through a plunger acting on the inner side of the cover at the same time with a sprinkler operation. In this regard, the lid is rotated with respect to a rotation axis arranged outside the space that can be closed by the lid from a closed position to an open position. When the sprinkler is turned off, the lid automatically rotates back to the closed position. Although a suction of the lid is difficult to pass over with a lawnmower through the plunger mechanism, it is not prevented safely.

The present invention is based on the objective of indicating a registration provision, particularly improved in terms of the danger of damage to the cover arrangement, of a garden irrigation system.

The invention is described in claim 1. The dependent claims contain advantageous configurations and improvements of the invention.

By at least partially displacing the cover surface of the registration cover in its opening position to the registration interior, the extent to which the registration cover protrudes above the registration housing in the position is at least considerably reduced opening, in a preferred embodiment is essentially completely eliminated.

The axis of rotation is disposed below the edge curve and in the vertical projection is located within the projection surface of the registration opening. This leads, with respect to the known registration cover arrangements with a swivel joint arranged at the edge of the registration and a registration cover which in the opening position is completely above the edge curve, to another assembly and movement Rotating the registration cover. In particular, the danger of an involuntary opening of the registration cover is suppressed by a negative pressure generated by a lawn mower, because a negative pressure of this type is counteracted in different surface fragments of the cover surface in terms of a pivot and thereby It almost neutralizes.

The terms horizontal and vertical refer to the orientation of the registration arrangement in its regular installation position on the ground.

The cover surface is bent upwards, advantageously against the edge curve, by which the approximately linear contact surface is understood in the closing position of the cover, on the upper registration side, between the mobile cover and the part fixed housing, which gives the lid an increased stability against the load by footfalls. The cover surface is extended through articulation supports towards the rotating joint arranged more deeply. The swivel joint advantageously has a large sliding joint surface around the axis of rotation with respect to the known arrangements, the radius of which advantageously amounts to at least 10% of the maximum diameter of the visible cover surface in the closed or opening state. registration in the case of an open lid.

The mounting of the lid on the rotating joint can be advantageously designed such that the lid during the opening movement quickly achieves a distance from the fixed edge that was previously in contact with the lid, a distance of one or few being sufficient. millimeters, to prevent the lid

rub with the edge along it with the danger of being plowed due to hard dirt particles. For such a movement, which can advantageously differ from a merely rotational movement around a rotating joint and cause a quicker slight descent of the cover by the edge, a guide curve, a lever joint, an offset can be advantageously used of the axis of rotation, etc.

Advantageously, the lid surface in the closed state of the lid or the opening released in the open state of the lid is separated from the outer edge of the registration arrangement by an annular surface by at least 10% of the diameter of the upper side of the provision of registration In this way, the danger of entering dirt particles or of getting caught in the surrounding environment can be reduced in particular. The annular surface advantageously forms part of an insertion body, which is removably inserted in a registration housing that remains permanently in the ground, the rotating joint being advantageously formed, around which the lid can rotate, between the insertion body and a cover body containing the cover surface. A retention device, which in the closing position of the lid applies a retention force that can be overcome manually and can be performed as a tightening or preferably as an interlocking, is advantageously arranged in the articulation arrangement and thereby in a protected position in mostly against the action of UV radiation.

The invention is illustrated in more detail below with reference to the figures. In that regard it shows:

Fig. 1, a registration arrangement with the lid closed in an oblique view,

Fig. 2, the arrangement according to Fig. 1 in a representation that allows to see the interior,

Fig. 3, a side view of Fig. 2,

Fig. 4, an oblique view in section with the lid open,

Fig. 5, an annular body that can be removed with a lid.

Fig. 1 shows in an oblique view from above a registration arrangement according to the invention, whose registration housing SG is divided into an upper fragment SO with an essentially circular cylinder-shaped wall and a lower SU fragment. From the representation in section according to Fig. 2 in a longitudinal vertical half plane as a cutting plane it is evident that in the upper carcass fragment SO the carcass wall essentially forms an enveloping surface in the form of a circular cylinder and in the fragment In the lower housing SU the registration base SB, which delimits the internal space of the registration arrangement downwards, descends from the external wall downwards towards the center. The registration base SB can advantageously present, as shown, a curved domed shape, but it can also take other forms and in particular also run flat.

The registration arrangement is closed on the upper side by means of an RF annular surface and a DF cover surface. The annular surface RF forms part of an insertion body, which is, with a wall RW extending vertically downwards, within the wall of the upper fragment SO of the registration housing and is advantageously supported with a surface projection annular that points radially outwardly beyond the wall RW on the upper edge of the fragment of record housing SO. The radial width of the annular surface RF in the radial direction with respect to the middle axis MA advantageously amounts to at least 10% of the external diameter of the annular body, which in the case drawn is essentially equal to the external diameter of the registration housing. A radial distance from the cover surface or from the opening covered by it with respect to the plant area and the surrounding soil reduces the danger of dirt particles falling into the log interior or that when closing the lid parts of plants are caught and do not close the lid properly.

The cover surface DF forms in the closed state of the cover shown in Fig. 1 and Fig. 2, the surface of the cover pointing upwards, visible to the user, which along an approximately linear surface , referred to below as the edge curve, is in contact with the RF annular surface and covers the registration opening surrounded by the RF annular surface. The RF cover surface may extend in that respect slightly below or above the annular surface in the area of the registration opening.

An appendix in the form of an HL grip flange is attached with the lid surface, which serves as a support point for a user's finger to open the lid, the lid being rotated by the grip flange Hl upwards. During the rotary movement, the cover is lowered at the same time in its fragment that is opposite the grip flange HL with respect to the middle axis MA down to the inside of the registration housing. In Fig. 4 a view corresponding to Fig. 2 is shown with the cover fully pivoted to the opening position, in which the cover surface DF is essentially completely lowered into the interior of the registration housing and already only The HL grip flange protrudes beyond the annular surface and serves as a grip support to close the lid.

The cover then contains the cover surface GS articulation supports that are located at opposite ends of the cover surface with respect to the axis of rotation SA, which carry the parts of the cover side of a rotating articulation arrangement and in particular They can be made with these and the cover surface DF as a one-piece plastic injection molding body. The articulation brackets GS advantageously serve at the same time to transmit a force acting on the cover surface, in particular when a person steps on the cover surface DF, through the swivel joint arrangement to the registration housing.

In the preferred example drawn, the rotating articulation arrangement is configured between the cover surface in said embodiment with articulation supports that continue from the cover surface DF on one side and an insertion body, which also contains the wall RW and the RF annular surface as a single-piece plastic injection molding body. Fig. 5 shows an insertion body of this type in relation to a cover arrangement in an elevated position with respect to the upper fragment SO of the registration housing. The rotating articulation arrangement contains in two rotating joints arranged oppositely in the direction of the axis of rotation SA in each case a GB joint bushing on the sides of the insertion body, in which an articulation joint is rotatably inserted GA configured in the associated Gs joint support of the cover arrangement. The contact surface between the joint joint GA and the joint sleeve GB advantageously has a radius, which amounts to at least 10% of the largest diameter of the registration opening surrounded by the annular surface RF. Due to a radius of such size, a large bearing surface of the joint joint GA against the joint sleeve GB is obtained in the event of a tread load of the cover surface and a distribution of the force to a surface of support of such size with a correspondingly smaller load of the surface in the rotating joint. Advantageously, the lower edge of the articulation bushing is supported by an SS step protruding inwards inside the registration housing.

The cover surface is advantageously bulged upwards in its fragment surrounded by the annular surface RF with respect to said edge curve RK, thereby resulting in a favorable distribution of forces in the case of a tread load of the cover surface.

The cover surface DF is with most of its surface portion closer to the axis of rotation SA than what corresponds to the radial distance of the edge curve RK from the axis of rotation SA in the respective associated axial position for the registration opening on the side of the lid that goes under the edge curve. Therefore, the cover surface is flattened. In this way, in the case of pivoting the cover and the entrance of the cover surface DF into the registration interior during the turning operation, an gap between the cover surface DF and the registration opening RK and the hard particles is generated that they are eventually in the area of the registration opening RK do not lead to the surface of the lid being plowed and may fall, if necessary, to the interior of the register and then do not block the closing operation. An additional softer material may also be provided along the edge curve, which can be applied in particular in a 2K injection molding process at the inner edge of the annular surface. A soft material can reduce the danger that the lid surface will be plowed and that water will enter.

An angle that is in a medium longitudinal plane corresponding to the cutting planes according to Fig. 2 to Fig. 4 between spokes of the axis of rotation at opposite points of the registration opening, is designated in Fig. 3 with WR. The angle WR advantageously amounts to at least 60 ° and / or at most 120 °. Preferably, the angle WR amounts to approximately 90 °. The angle of rotation, by which the lid can be pivoted between the closing position shown in Fig. 2 and the opening position shown in Fig. 4 around the axis of rotation, advantageously also amounts to at least 60 ° and / or at most 120 °. The pivot angle between the closing position and the opening position preferably amounts to approximately 90 °.

The cover can be held in the closed position advantageously by means of an additional retention device with a retention force that can be overcome manually, the retention device being able to form, for example, a clamping device or preferably an interlocking. An interlocking of this type is advantageously made of plastic and is disposed at a point protected mostly against UV radiation and is configured in the preferred example shown in Fig. 5 in the area of the rotating articulation arrangement. An interlocking may be given, for example, by an elastic rib FR on the insertion body, which forms a complementary structure to an interlocking structure connected to the lid side part of the rotating joint. In the embodiment, a protuberance configured in the axial joint GA is retained by interlocking in an additional protuberance configured in the spring rib FR, oriented opposite the axis of rotation SA. By applying a manual opening force on the grip flange HL, the spring rib FR is pressed radially away from the rotation axis SA and the protrusions in the joint joint GA and in the spring rib FR jump one above the other exceeding the retention force essentially determined by the spring force of the FR spring rib and allows an additional rotation of the cover around the axis of rotation to the opening position. A limitation of the rotational movement may be given in particular by a stop of the grip flange Hl at the inner edge of the RF annular surface. A retention device may also contain an arrangement of magnets in an advantageous embodiment.

The cover arrangement advantageously presents from the cover surface DF, an arc BO, which stabilizes the shape of the cover body, reaches beyond the GS articulation supports. The arc BO is in the closing position of the lid pointing downwards inside the registration and in the opening position shown in Fig. 4 of the lid surrounds the registration opening enclosed by the annular surface RF on the side opposite to the cover surface DF.

A functional unit, which can be arranged in the registration housing, is advantageously located in the center of the registration in the middle axis MA and thus can be easily reached through the registration opening released in the lid opening position. . A functional unit of this type, which can be, for example, a coupling piece which, if necessary, can be locked from an insert coupling system, can be advantageously retained in the register through a connection unit inside registry. A connection unit of this type may in particular be a connection joint ST connected in such a way that it conducts water with a water inlet WE that is underground. However, the functional unit may also be formed by other different elements, such as for example an electromagnetic valve or one that can be operated manually, a rolled hose, etc.

The registration base SB can be advantageously made so that it descends towards the center from the external wall of the registration housing, in particular also curvedly bent. Advantageously, in the closing position of the lid according to Fig. 2 and Fig. 3, the arc BO and / or in the opening position of the lid according to Fig. 4, the cover surface DF enters the vertical area of the registration base that runs tilted. By tilting the registration base, the impurities that eventually reach the interior of the register accumulate in the center of the register and thus can be easily removed in the opening position of the lid. The registration base can advantageously contain outlet and ventilation openings, in the example drawn in the form of radially running slots AS. The width of the grooves or in general the diameter of the base openings of this type is advantageously less than 1 mm, in particular less than 0.5 mm, to prevent as far as possible the entry of insects into the interior of registry.

A cleaning of the registration interior can be facilitated in particular by combining the insertion body and the cover that can be removed as a unit, as shown in Fig. 5, since then access to the registration interior is given through the opening enlarged with the diameter of the cylindrical wall of the upper registration housing fragment SO. The registration base may be formed or covered by a removable insert.
