Description

introduction

The present application relates to a sprinkler for sprinkling a base plate of a device for compaction of a substrate or for sprinkling of the substrate to be compacted, comprising a liquid container for holding a liquid having an enclosed space bounding elements interior, and at least one elongated distribution device for distributing the liquid via a sprinkling path, the liquid container having at least one filling opening for filling liquid into its interior, wherein the liquid container and the distribution device are at least indirectly fluidically connected to one another such that the liquid discharged from the interior of the liquid container can be conducted to the distribution device, wherein the Fluidic connection between the liquid container and the distribution device either openable un d is closable, wherein the distribution device advantageously comprises a plurality of openings through which the distribution device supplied liquid can emerge from the former out.

Furthermore, the present application relates to a method for sprinkling a base plate of a device for compacting a substrate or for sprinkling a substrate to be compacted, comprising the following method steps:

1. a) A liquid container of a sprinkler is filled with a liquid to be used for irrigation.
2. b) A fluidic connection, which fluidly connects the liquid container with a distribution device at least indirectly, is opened, so that the liquid held in the liquid container flows to the distribution device.
3. c) Starting from the distribution device, the liquid is passed to a surface to be sprinkled.

For the purposes of the present application, "room delimitation elements" are understood as meaning elements which are suitable for spatially enclosing the interior of the liquid container. It is not mandatory that the room boundary elements surround the interior in a completely sealed manner. For example, it is harmless if on one upper side of the liquid container one or more openings remain, through which the liquid could escape. The interior of the liquid container should be so tightly enclosed in each case by means of the space delimiting elements that in the presence of the liquid container in a rest position and in its intended orientation, a liquid therein can not flow uncontrollably from the interior. In typical liquid containers for known irrigation devices, the space-limiting elements, preferably the entire liquid container, are formed by plastic.

A "distribution device" in the context of the present application describes such a device by means of which the liquid emerging from the liquid container can be distributed via the sprinkling path. Typically, the distribution device is supplied from the liquid container originating liquid (usually water) only at a dedicated supply point of the distribution device, for example via a connecting piece, which is fluidically, for example by means of a hose member, connected to the liquid container. Starting from this dedicated location of the distribution device, the liquid can be distributed over a length of the distribution device (for example, in an inner cavity of the distribution device) and thus distributed over a certain width of the base plate or the substrate to be compacted. The distribution device is usually arranged relative to the ground horizontally or transversely to the direction of movement of the respective device for compaction of the substrate.

Typical distribution devices are in the form of elongated tubes, which are distributed over the length thereof provided with a plurality of small openings. The liquid to be distributed is typically supplied to such a tubular distribution device at a supply point and then distributed laterally within the distribution device. The diameters of the openings are chosen so small that they fulfill the function of a throttle. This means that the entire liquid volume flow, which flows to the distribution device, can not be removed from the distribution device directly by means of the first openings, which are arranged adjacent to the supply point. Instead, these openings are overflowed, with the liquid ultimately flowing to all of the openings in the distribution means and exiting the individual openings at a generally identical pressure. As a result, this leads to the liquid intended for irrigation exits all distributed over the length of the distribution device openings and thus distributed to the desired area total.

As a rule, the liquid container and the distribution device are fluidically connected to one another by means of a connecting element. Such a connection element may, for example, be a flexible hose which is connected both to the liquid container and to the distribution device. Such a connection of distribution device and liquid container constitutes an "indirect fluidic connection" within the meaning of the present application. In contrast, an immediate fluidic connection would not require an intermediate connection element in order to supply the liquid from the liquid container to the distribution device.

The process step of filling the liquid container set forth in connection with the method described above is typically carried out on a stationary liquid source, in particular a water source. In particular, the sprinkler used may be made portable so that it can be transported to the liquid source. The filling then takes place through a filling opening, which is arranged on the liquid container.

State of the art

A sprinkler and a method for sprinkling a surface are already known in the art. Sprinkling can basically be beneficial for a variety of reasons. Often it is used when a compression of a substrate is to accomplish, which has a greatly elevated temperature, for example when processing a freshly applied asphalt layer. The sprinkling of such an asphalt layer with a liquid, in particular with water, should prevent sticking of the base plate of the compacting device to the substrate. Likewise, irrigation in connection with the avoidance of excessive dust formation in the course of a compression process is conceivable. It is understood that in addition to those mentioned all other applications are conceivable in which a sprinkling appears to be advantageous with a liquid.

As an example, let's look for a generic sprinkler on the European patent application EP 2 138 636 A1 directed. This describes a sprinkling device comprising a liquid container and a distribution device. The distribution device is designed in the form of an elongated tube, by means of which the liquid originating from the liquid container via a Sprinkler track is distributable. The sprinkler device according to the cited document is characterized in that an actuating device is located within the fluid container, by means of which a fluidic connection between the fluid container and the distributor device can be activated and deactivated from an upper side of the fluid container. For this purpose, a pressure rod is used, which can lift a seal of a liquid outlet of the liquid container from its sealing seat and in this way can release the fluidic connection. This pressure rod is operable by means of a corresponding lever from the top of the liquid container forth.

An approximately comparable device is the German Offenlegungsschrift DE 10 2007 026 419 A1 removable. This has as a distribution device via an upwardly open channel whose flow cross section is so small that it "overflows" in the course of supplying the liquid to be used for irrigation, wherein the liquid over the length of the distribution device is distributed over the overflow edge of the channel. In this way, a distribution of the liquid over a sprinkling distance is achieved.

The known sprinklers have the particular disadvantage that they must be equipped in each case with a valve device which is required for switching the fluidic connection between the liquid container and distribution device.

task

The present application has for its object to provide a sprinkler, which is constructed simpler compared to the prior art.

solution

The underlying object is achieved on the basis of the sprinkler of the type described above according to the invention that the distribution device penetrates at least one room boundary element, preferably a plurality of space boundary elements of the liquid container, wherein the distribution device extends over part of its length within the interior of the liquid container. In this way it is ensured that the distribution device and an inner volume of the liquid container are in contact with each other in such a way that an immediate fluidic connection between the two components can be produced.

In order to seal the liquid container and the distribution device against each other, the liquid container comprises at least one sealing element, which is in sealing contact both with at least one space delimiting element of the liquid container and with the distribution device and in this way seals the two components against each other.

The "penetration" of a space limiting element of the liquid container describes that the distribution device pierces the respective space delimiting element such that the distribution device on one side of the space delimiting element at least with a part of its cross section, preferably with its entire cross section, outside of the liquid container and on the other side of the Room boundary element located at least with a part of its cross section, preferably with its entire cross section, within the liquid container. The respectively penetrated space delimiting element has for this purpose a corresponding opening, through which the distribution device is guided.

The sealing element is designed so that a passage of liquid present in the liquid container through a joint, which results at a penetration point of the space delimiting element, at which the distribution device penetrates the respective space delimiting element, between the distribution device and the space delimiting element, at least substantially, preferably completely, is prevented.

The sprinkler according to the invention has many advantages. In particular, it makes it possible for the liquid stored in the liquid container to flow directly from the interior of the liquid container to or into the distribution device. For this purpose, the liquid must not first be led out of the liquid container by means of an additional component, wherein a fluidic connection with a dedicated valve must be switched. By means of the implementation of the distribution device through the interior of the liquid container, it is instead possible to produce a fluidic connection between the distribution device and the interior by means of a relative movement between the distribution device and the liquid container. In particular, it is conceivable to rotate the distribution device relative to the liquid container. This is particularly useful when the distribution device is tubular, with a rotation of the distribution device about its longitudinal axis, which simultaneously forms the axis of rotation, is preferable.

In order to facilitate a movement of the distribution device relative to the liquid container, in particular in the case of a relative rotation of the components to one another, it may be advantageous to design the distribution device rotationally symmetrical. This is particularly advantageous with regard to the design of the at least one sealing element.

Another advantage that results from the arrangement of the distribution device according to the invention partially within the liquid container, is the fact that in this way both components are executed so to speak "integral". That is, after assembling the showering device, the distribution device and the liquid container are usually a structural unit which can be mounted as a whole on or dismounted from a respective compacting device. Thus, it is not necessary, for example for the filling of the liquid container with liquid, the liquid container first by the distribution device, which is typically arranged in the prior art fixed to the respective compression device to solve and then reconnect; instead, both the liquid container and the distribution device can be moved together in each case, so that an additional effort in the course of filling the liquid container deleted.

In an advantageous embodiment of the sprinkler device according to the invention, the distribution device penetrates at least two, preferably at least four, space-limiting elements of the liquid container. In this case, the length of the distribution device preferably exceeds the width of the liquid container. In this way, the distribution device is able to distribute the liquid supplied to it over a larger sprinkling distance than would be possible solely by means of the liquid container. Particularly simple to imagine is a construction in which the distribution device on one side of the liquid container penetrates through a space delimiting element of the same into the interior of the liquid container and exits on an opposite side through another space delimiting element again from the liquid container. Such a distribution device has a penetration area extending between the space boundary elements of the liquid container. This penetration area has a length that is less than the total length of the distribution device in each case.

In a particularly advantageous embodiment of the sprinkler, the distribution device and the liquid container are movable relative to each other, in particular rotatable relative to each other. The relative movability allows one Fluidic connection between the interior of the liquid container and the distribution device to open or close directly by operating the distribution device. In particular, it is possible to move the distribution device between an open position and a closed position, wherein in the presence of the distribution device in its open position, the fluidic connection between the liquid container and the distribution device is opened and said fluid communication is closed in the closed position in the presence of the distribution device.

For example, it is conceivable that the distribution device have an opening which corresponds to an opening of the liquid container. If one imagines the distribution device by way of example as an elongated tube, such an opening could penetrate radially, for example, a lateral surface of the tube. The corresponding opening of the liquid container could be introduced, for example, in the sealing element, so that the distribution device is sealingly sealed at least over a certain sealing distance inside the interior of the liquid container. By means of a movement of the distribution device relative to the liquid container and thus, for example, relative to a sealing element of the liquid container, the mutually corresponding openings of the distribution device and the liquid container can be brought into coincidence (fluidic connection opened) or vice versa be performed so that they no longer overlap (fluidic connection closed).

In this embodiment, the distribution device itself effectively acts as a valve by means of which the supply of the liquid to the distribution device can be controlled. The possibility of twisting the distribution device as a special embodiment of a relative movement between the distribution device and the liquid container is in this respect additionally advantageous, as a translational movement of the distribution device relative to the liquid container does not occur.

A freedom of movement of the distribution device relative to the liquid container may be limited, for example, by means of stop elements, so that accidental movement of the distribution device is blocked beyond a reasonable extent. Such stop elements could for example be designed in the form of radially projecting lugs, which can collide with a corresponding stop surface of the liquid container.

A fluidic connection produced by means of a relative movement between the distribution device and the liquid container is advantageously direct, that is to say without the interposition of a further, liquid-conducting component, for example a hose. In such an embodiment, the otherwise commonly required in the prior art additional components omitted, so that the construction of the sprinkler as a whole compared to the prior art decreases in complexity.

As already indicated above, it may be particularly advantageous if the liquid container and the distribution device have corresponding openings which can be brought into coincidence by means of a movement of the distribution device relative to the liquid container, so that the liquid held in the liquid container can flow to the distribution device. In such an embodiment, it may be particularly advantageous if the same sealing element, which accomplishes a sealing of the liquid container against the distribution device in the region of at least one Durchdringungsstelle, additionally causes a seal of the respective flow connection opening of the distribution device against the interior of the liquid container.

A corresponding sealing element that performs both the sealing of the penetration point as well as the interior of the liquid container against the distribution device and thus effectively fulfills a dual function may extend, for example, starting from the penetration point at the respective space delimiting element of the liquid container into the liquid container, wherein the sealing element Distribution device at least partially surrounds, so that the fluidic connection between the interior of the liquid container and the distribution device is sealable.

As already indicated above, it is particularly conceivable that the distribution device has a radial bore which can cooperate with an associated opening in the sealing element. The thus corresponding openings of the sealing element and the distribution device can then be brought into coincidence with each other by means of a relative movement of the distribution device and the liquid container or out of their coverage out.

It is understood that a sealing element, which causes the interior of the liquid container against the distribution device, regardless of the above-described dual function of the sealing member so fixed relative to the liquid container must be designed so that the relative movement of the distribution device to the liquid container equally corresponds to a relative movement of the distribution device to the sealing element.

In the event that a relative mobility between the distribution device and the liquid container in the form of a relative rotatability of the two components is carried out to each other and also in the distribution device is a rotationally symmetrical body, in particular a tubular element, it may be advantageous, the sealing element , which seals the liquid container in the region of the penetration point of the respective space delimiting element against the distribution device, to arrange inclined relative to the axis of symmetry of the distribution device such that the axes of symmetry of the sealing element and the distribution device are not arranged parallel to one another. Such an embodiment is conceivable, for example, in that the opening through which the distribution device penetrates the space delimiting element of the liquid container is designed "obliquely", so that as it were a central axis of this opening extends inclined relative to the longitudinal axis of the distribution device. In this case, an inclination of a few degrees, in particular less than 10 °, is sufficient.

The effect of this arrangement is that the axis of rotation of the distribution device and the corresponding sealing element do not run parallel to each other and therefore do not coincide. This embodiment thus provides a mechanical protection against the fact that the sealing element is accidentally rotated in the course of rotation of the distribution device relative to the liquid container. If the latter were the case, in particular in those sealing elements which perform a dual function described above, possibly a rotation of the distribution device relative to the liquid container could not be used to switch the fluidic connection between the interior of the liquid container and the distribution device.

The sprinkling device according to the invention further ausgestaltend, the liquid container on at least one cheek area, preferably at least two opposing cheek areas, which extend in a direction away from the filling opening direction of the remaining liquid container. This embodiment is based on the consideration that the liquid containers are arranged in the mounted state of the sprinkler typically in an upper region on the upper carriage of the respective device for compacting a substrate. At the same time an associated distribution device is typically close to the base plate of Compaction device arranged so that the liquid provided for irrigation can be performed as close to their destination from the distribution device out. In order to bridge the distance between the liquid container and the distribution device, both components in the prior art are typically interconnected by means of a hose member.

In the sprinkler according to the invention, however, it is imperative that the distribution device penetrates at least one space-limiting element of the liquid container and thereby penetrates into the interior of the liquid container. An arrangement in which the liquid container and the distribution device are located away from each other is therefore not possible here. The described cheek areas are therefore advantageous in order, as it were, to guide the liquid container down from a mounting point on the respective compacting device into a region near the bottom of the compacting device in which the distribution device can then be arranged. In this way it is possible to position the distribution device - as in the prior art - in the vicinity of the substrate to be compacted or the base plate of the compacting device and nevertheless to penetrate the liquid container or at least one space-limiting element thereof.

The distribution device advantageously penetrates the liquid container in a lower end section of the liquid container so that the liquid held in the liquid container can be at least substantially completely removed from the liquid container by means of the distribution device. This is based on the consideration that all liquid that is located within the liquid container to a certain extent below the distribution device, can not automatically enter upon opening of a corresponding fluidic connection in the distribution device and therefore for sprinkling by means of the sprinkler is not available. If the liquid container is equipped with the at least one, in particular two, cheek areas, the distribution device advantageously penetrates the liquid container in the cheek area (s).

The at least one sealing element, by means of which the respectively penetrated space delimiting element is sealed against the distribution device, is advantageously designed such that it extends on both sides of the penetration point at which the distribution device penetrates the space delimiting element. In particular, the sealing element can be designed such that it sealingly encloses the distribution device on both sides of the penetration point. Such Embodiment is advantageous for the reliability of the seal between the distribution device and the liquid container, since a flow path, which must cover a liquid particle between the sealing element and the distribution device, is particularly long.

Furthermore, it can be of particular advantage if at least one sealing element, over the entire penetration region, over which the distributor device extends through the interior of the liquid container, surrounds the distributor device, preferably completely. Furthermore, this sealing element, which encloses the distributor device in the penetration area, is advantageously the same sealing element which also seals the penetrated space-limiting element (s) against the distributor device. Such a sealing element thus has an elongated shape which extends from a penetration point of the liquid container along the distribution means. The sealing of the distribution device over the length of the penetration area helps to virtually completely keep the liquid present in the liquid container from the distribution device, so that undesired entry of the liquid into a joint between the sealing element and the distribution device is not possible. In such an embodiment, a direct contact between the liquid and an outer surface of the distribution device could take place only in a region in which corresponding openings of the liquid container and the distribution device (fluidic connection) are arranged.

For the embodiment of the sealing element, it can also be advantageous if the same has a mounting portion, which - viewed in an installed state of the sealing element - extends outside of the liquid container. Such a mounting portion may be used, for example, to grasp the sealing element so as to pass it through the aperture (s) in the space-limiting element (s) forming the penetration points for the distribution device, and in this way install the sealing element , For this purpose, said mounting portion of the sealing element is advantageously provided with at least one opening, which can be gripped, for example by means of a tool or a finger, to exert a tensile force on the entire sealing element. By means of such a mounting portion, a pulling of the sealing element through the corresponding openings of the liquid container is particularly easy.

Starting from a method of the type described above, the underlying object is achieved in that the distribution device is moved relative to the liquid container, being released by the action of this movement, preferably immediate, fluidic connection between the liquid container and the distribution device. As already described above, a rotational movement is particularly advantageous for this purpose.

The inventive method makes it possible to dispense with a separate valve element for switching the fluidic connection between the liquid container and the distribution device and in this way to reduce the complexity of the sprinkler. In addition, the method step according to the invention is particularly simple executable, in particular on a construction site no additional tool is necessary to accomplish the activation or deactivation of the sprinkler as a whole. Instead, it is only necessary to grasp and move the distribution device, which penetrates at least one space-limiting element of the liquid container and extends over part of its length within the interior of the liquid container and sealed by a sealing element of the liquid container against the space-limiting element and to move relative to the liquid container , especially to twist. The workflow interrupting measures such as the finding of connecting means or associated tools, as it is often complained of in the art in practice, thus no longer occurs.

The present embodiment, in the FIGS. 1 to 7 is shown, comprises a sprinkler 1, which is mounted on a device 2 for compressing a substrate, not shown. The sprinkler device 1 in turn comprises a liquid container 3, which has an interior 5 enclosed by room delimiting elements 4 . At an upper side of the liquid container 3 is a filling opening 7, through which the liquid container 3 can be filled with a liquid. The liquid container 3 is formed here by plastic.

In a lower end region 21 of the liquid container 3 , the irrigation device 1 has a distribution device 6 . The lower end portion 21 of the liquid container 3 is disposed near a bottom 19 of the liquid container 3 . The arrangement of the distribution device 6 in the lower end region 21 is advantageous insofar as the liquid stored in the liquid container 3 can flow into the distribution device 6 almost entirely solely on account of the acting force of gravity. The distribution device 6 is provided with a plurality of openings, which are not shown in the figures. By means of these openings, it is possible for the distribution device 6 to distribute the liquid supplied to it over a sprinkling path.

The distribution device 6 is here in the form of an elongated, rotationally symmetrical steel tube, which is closed at its ends in each case with a closure cap 20 . In this way, the distribution device 6 in turn includes an interior, within which one of the distribution device 6 supplied liquid can distribute horizontally. This interior of the distribution device 6 is particularly good in FIG. 3 recognizable.

The distribution device 6 is arranged so that it penetrates the liquid container 3 at a total of four penetration points 22 . At these penetration points 22, the liquid container 3 has corresponding openings, through which the distribution device 6 can extend. The distribution device 6 penetrates the liquid container 3 in cheek areas 13, 14 of the liquid container 3, which extend in a direction away from the filling opening 7 on the liquid container 3 and n a lower end of the liquid container 3 . These cheek areas 13, 14 serve, as it were, to move the liquid container 3 into an area near the substrate pull, so that the liquid container 3 penetrating distribution device 6 is arranged in the smallest possible distance from the respective substrate to be compacted or a respective base plate 18 of the device 2 for compacting the substrate. Both cheek areas 13, 14 of the liquid container 3 are enclosed in each case with space-limiting elements 4 , so that the penetration of the liquid container 3 in the cheek areas 13, 14 requires a total of four space-limiting elements 4 . This results in the above-mentioned four total penetration points 22, in which space boundary elements 4 of the liquid container 3 are penetrated by the distribution device 6 .

The distribution device 6 has a length 9 which exceeds a width 10 of the liquid container 3 . In this way it is possible for the distribution device 6 to distribute the liquid supplied to it over a longer sprinkling distance than would be possible solely by means of the liquid container 3 .

The penetration of the liquid container 3 by means of the distribution device 6 is particularly good in FIG. 3 recognizable. In order to seal the liquid container 3 or its interior 5 against the distribution device 6 , the liquid container 3 comprises a total of two sealing elements 8 formed by an elastomeric plastic. These sealing elements 8 are made elongated. They are particularly good based on the details according to FIG. 4a and FIG. 5a recognizable. The sealing elements 8 serve primarily to prevent inadvertent leakage of liquid from the interior 5 of the liquid container 3 out. For this purpose, the sealing elements 8 seal the space-limiting elements 4 in the region of the penetration points 22 against the distribution device 6 .

Furthermore, the sealing elements 8 are designed here so that they almost completely surround the distribution device 6 in a respective assigned penetration region 15 of the distribution device 6 , that is, seal against the inner space 5 of the liquid container 3 . This is especially good on the details according to the FIGS. 4a and 5a recognizable. By means of this seal, an outer circumferential surface of the distribution device 6 is almost completely isolated from the liquid present in the liquid container 3 . An exception to this is only two openings 11, which penetrate a respective sealing element 8 radially. These openings 11 serve to be able to produce a fluidic connection between the interior 5 of the liquid container 3 and the distribution device 6 or its interior.

To activate this fluidic connection, it is only necessary, with the openings 11 of the sealing elements 8 corresponding openings 12 which penetrate the walls of the distribution device 6 radially, to bring with the openings 11 of the sealing elements 8 in registration. If this is the case, the distribution device 6 is in its open position. This open position of the distribution device 6 is in FIG. 4 recognizable. It follows that the openings 11 of the sealing elements 8 and the openings 12 of the distribution device 6 overlap or overlap and thus a flow of liquid held in the liquid container 3 into the distribution device 6 is possible.

Starting from its open position, the distribution device 6 can be transferred by means of a rotation about its longitudinal axis relative to the liquid container 3 and the sealing member 8 in its closed position in which the openings 11 of the sealing elements 8 and the openings 12 of the distribution device 6 do not overlap. This closed position of the distribution device 6 is FIG. 5 removable. It follows that, in this closed position of the distribution device 6, a flow of the liquid stored in the liquid container 3 into the distribution device 6 is not possible. Consequently, the sprinkler 1 is deactivated in the presence of the distribution device 6 in its closed position as a whole.

The distribution device 6 is provided in the example shown here laterally outside the liquid container 3 with a peripheral stop ring 23 which blocks movement of the distribution device 6 relative to the liquid container 3 in a direction parallel to a longitudinal axis of the distribution device 6 . In this way it is ensured that in the course of the rotation of the distribution device 6 whose translational position remains unchanged relative to the liquid container 3 . Since the distribution device 6 is provided on both sides with a stop ring 23 , a movement of the distribution device 6 is prevented along its longitudinal axis in both directions.

The sealing elements 8 are provided outside of the liquid container 3 each with a mounting portion 16 . In this mounting portion 16 , the sealing elements each have openings 17, by means of which it is possible to interlock positively with the sealing element 8 . In particular, it is possible to grip the sealing elements 8 in the mounting section 16, for example by means of a finger or a corresponding mounting tool, and thus starting from one side of the space-limiting elements 4 through the openings at the penetration points 22 to pull through. In this way, the sealing elements 8 are particularly easy to install.

To ensure that the sealing elements 8 are as firmly as possible connected to the space limiting elements 4 of the liquid container 3 and, for example, not unintentionally move relative to the liquid container 3 , the sealing elements 8 to a certain extent "too small" designed so that they in the course of their Mounting on the liquid container 3 must be at least slightly expanded elastically. As a result, a restoring force is formed in the sealing elements 8 , which causes the respective sealing element 8 to press against the respectively corresponding space-limiting element 4 . By this pressing a friction between the sealing elements 8 and the corresponding space-limiting elements 4 is increased, which in turn a relative movement of the two components is difficult to each other.

The sealing elements 8 are made elongated in the embodiment shown and rotationally symmetrical. The axes of rotation of the sealing elements 8 are oriented so that they do not run parallel to a rotational axis of the distribution device 6 . The deviation of the orientations of the axes of rotation of the sealing elements 8 and the distribution device 6 are so small that they are not visible in the figures. The purpose of this different orientation of the axes of rotation is that an accidental "entrainment" of the sealing elements 8 in the course of rotation of the distribution device 6 is difficult.

The features disclosed above in connection with the present exemplary embodiment can also be implemented independently of each other on a sprinkler device 1 according to the invention, if this appears technically possible to the person skilled in the art. In that regard, the individual characteristics combined here are necessarily dependent on each other.
