    PUSH COUPLING
    Technical area
    The present invention relates to a push coupling and a method for ensuring that rudders have been connected correctly to a push coupling. Push couplings are used, for example, to connect pipes that conduct water.
    State of the art
    Push couplings are used, for example, to connect pipes in spring drainage systems and tap water systems, often in concealed installations, behind walls or under floors. Rows that are connected years often row plastic. In a push coupling, a rudder is connected to the coupling by pushing the rudder into the push coupling. A shrinkage of the coupling to the rudder is not done.
    One of the many problems with today's push couplings is how far the rudder should be pushed in. The rudder must be pushed in long enough so that the push coupling tightens properly. Improper handling or coupling normally leads to leakage. Rudders that are pushed in a good distance but still not sufficiently do not start to leak until after the coupling has been tested after assembly, or later when the rudders have been taken into use, e.g. two months later. It is difficult to solve one or more of these problems.
    Push couplings cannot be used, or only poorly, with rudders that are chrome-plated. This is due to the chrome-plated surface of the chrome-plated rudder. Leakage is a problem as a result of chrome-plated pipes being used. It is difficult to solve one or more of these problems.
    It is difficult for a coupling to indicate when a rudder has been connected correctly so that no leakage occurs. It is difficult for such an indication to be clear and distinct and easily accessible. The indication should preferably take place when the installation is carried out. The indication should preferably be reliable. It is difficult to solve one or more of these problems.
    It is sought to provide a push coupling that is easy to manufacture. It is sought that the push coupling is economical to manufacture. A connection that is complicated and complicated to avoid. These properties are also difficult for a method to ensure that the rudders have been connected correctly to a push coupling.
    Summary
    The object of the present invention is to provide a push coupling for rudders and a method for ensuring that rudders have been connected correctly to a push coupling. This information is obtained by the wounds specified in the subsequent independent claims. More wounds are characterized by the dependent claims.
    According to an embodiment of a push coupling for rudders, the push coupling comprises a housing (10) with at least one opening (12) for a rudder; at least one sealing element (30) for sealing between a rudder and the housing (10); and at least one locking element (44) for fixing a rudder in the housing (10). Furthermore, the push coupling comprises at least one displacement element (22) inside the housing (10), the displacement element (22) being axially displaceably arranged to allow a tube to move the displacement element (22) and the displacement element (22) indicating by a displacement that the sealing element ( 30) fulfills its function, ie. toe takes. The housing has only openings for the rudder, and in some cases for a valve, but not other openings such as windows. This results in a coupling that does not lock. Furthermore, a coupling is obtained which indicates that the rudders have been connected correctly to the push coupling and fulfill their function. A good water flow is obtained when the sealing element is arranged on the inside of the housing (10) and arranged to peel towards the outside of a rudder.
    According to an embodiment of push coupling for rudders, the push coupling comprises an element (26) which together with the displacing element (22) produces a sound when the displacing element (22) is moved. According to one embodiment, the displacement element (22) comprises a resilient part (24) which snaps over the element (26) when the displacement element (22) is displaced and thereby produces the sound.
    According to an embodiment of push coupling for rudder, the push coupling comprises that a movement of the displacement element (22) gives an audible confirmation that the sealing element (30) has direct contact with a rudder in the push coupling and that the rudder is then fixed by the locking element (44).
    An embodiment is a method for ensuring that the rudders have been connected correctly to a push coupling. The method includes the step of the push clutch producing a sound when the rudders have been properly connected to a push clutch. Through hair, no visual confirmation is needed that the rudder has been connected correctly to a push coupling. Furthermore, you can thus ignore the fact that the rudder has been connected correctly to a push coupling. According to an embodiment of the method for ensuring that the rudders have been connected correctly to a push coupling, the method comprises a push coupling as described herein. At least one embodiment solves one or more of the problems with the prior art. For example, chrome-plated raw copper rudders can be connected to the push coupling. Several technical advantages of the present description will become apparent to one skilled in the art from the following description and claims. No technical advantage is critical for the example of the embodiments. Each embodiment and claim can be technically combined with the previous embodiment and claim.

    Detailed description
    Various examples of embodiments of the invention are described. A push coupling normally has an axial direction which is normally the direction in which a rudder is coupled to the push coupling. This means that the axial direction is normally the direction in which the fluid in the coupling can flow. Is the push coupling e.g. L or T formed so the axial direction corresponding to L or T is directed. A push coupling also has a radial direction that is angular towards the axial direction. In other words, a push coupling normally has the same mathematical layout as a cylinder. In this description, reference is made to these axial and radial directions.
    By a push coupling for rudders is meant a coupling where one or more rudders can be pushed into the coupling without the use of tools. One or more tubes can be connected via such a push coupling and a wave for a fluid is quickly and safely provided.
    The English term "push-coupling" corresponds to the Swedish term "push-coupling". A clutch that shrinks on the rudder is not a push clutch.
    Figure 1 shows an example of an embodiment of a push coupling. Figure 2 shows an example of an embodiment of the push coupling with two rudders. This push coupling is straight. In other words, this push coupling is I-shaped. Push coupling is intended for rudders, to couple rudders, e.g. to connect one rudder to another rudder so that a liquid or gas can flow from one rudder to the other. Figure 3 shows an example of an embodiment of the push coupling for connection to a surface (78), e.g. a cradle. According to these three embodiments, the push coupling comprises a housing (10) with at least one opening (12) for a rudder. In Figure 1, two openings (12, 14) have been illustrated. A rudder can be connected to each opening (12, 14). The rudder connected to the coupling is not included in the embodiment of the push coupling. This has been expressed in the claims in that the coupling is only suitable for rudders. The figures illustrate exemplary embodiments of the push coupling when the push coupling is shown in section and these exemplary embodiments are intended for round tubes. Other forms of rudder are conceivable, e.g. square. The outer shape of the push coupling can itself be round or of another shape, e.g. triangular or square.
    The housing (10) has in one design example, which can be combined with all design examples, only openings for pipes and in some cases a valve. The housing (10) thus has no window or opening for viewing internal parts of the housing (10) (for indication of the function of the coupling). In other words, the housing (10) has only openings for pipes to be connected.
    The push coupling further comprises at least one sealing element (30) for gripping between a rudder and the housing (10). This sealing element (30) can be an o-ring. The sealing element (30) can connect directly to the housing (10). When a rudder has been inserted into the push coupling and the rudder has been coupled, then the rudder can connect directly to the sealing element (30). The sealing element (30) can, e.g. only connect to the outside of the rudder, and then only directly between the outside of the rudder and the inside of the housing. An extra sealing element, e.g. on the inside of the rudder, year then not necessary. A problem that the embodiments described here solve is that the push coupling can indicate that the sealing element (30) corrodes the coupling, i.e. that a rudder inserted in the push coupling connects to the sealing element (30). The sealing element (30) is arranged on the inside of the housing (10), i.e. a side facing the center of the housing. Through this, sealing element (30) can connect, tighten, only to the outside of a rudder and a good flow through the push coupling is obtained as a result.
    The push coupling further comprises at least one locking element (44) for fixing a rudder in the housing (10). The locking element (44) can be designed as a washer with inwardly directed teeth. The teeth can bite into a rudder and allow a rudder to be pushed into the push coupling but not pulled out. The rudder cannot be pulled out because the teeth bite obliquely in the opposite direction. The rudder can be pulled out with another mechanism described below. The locking element (44) can be strongly designed and / or securely fastened in the push coupling, as described below, so that even chromed tubes can be fixed. Through it, chrome-plated rudders, e.g. chrome-plated copper rudder, coupled with the push coupling.
    The push coupling further comprises at least one displacement element (22) inside the housing (10). The displacement element (22) is axially displaceably arranged to allow a rudder to move the displacement element (22) and the displacement element (22) indicates by a displacement that the sealing element (30) fulfills its function. The displacement element (22) can be a circular element designed as a flange or a cylinder. The displacement element (22) can be of such a thickness that a rudder which does not fit the push coupling does not move the displacement element (22). When a displacement, a displacement, of the displacement element (22) takes place, the push coupling indicates that the sealing element (30) fulfills its function, namely toes. The function is fulfilled by the sealing element (30) sealing directly (or indirectly) between a rudder and the housing (10). The transfer element (22) can thus be moved by a rudder which, through the movement, takes the place of the transfer element at the sealing element (30). As a result, the transfer element (22) can allow a rudder to come into direct contact with the sealing element (30). The push coupling is thus designed so that the sealing element (30) only peels when the displacing element (22) has been removed from the sealing element (30). In one embodiment, the displacement member (22) may be arranged in a understood position in contact with, together with, the sealing member (30), and axially displaceable, movable, arranged to allow a tube to displace, move, the displacement member (22) to a second position. This second position is only reached when the rudder has moved the displacement element (22) away from the sealing element (30). The first position is illustrated in Figure 1 and the second position of the moving element (22) is the position that the moving element (22) has when the moving element (22) has been moved away from the understood position. In one embodiment, the sealing element (30) in the push coupling only tilts when the displacing element (22) has been moved from the understood position to the other position of a rudder. The correct function of the push coupling can thus be indicated by the movement element (22) having been moved from the understood position.
    As a clarification, the displacement element (22) can be in contact with the sealing element (30) before the push coupling is used and the displacement element (22) can be moved by a rudder which is coupled to the push coupling. The sealing element (30) can then connect only on the outside of the rudder. For example, the sealing element (30) may be in direct contact with the rudder and the housing (10) when the rudder has been connected to the push coupling. In an exemplary embodiment, the push coupling comprises an element (26) which, together with the displacement element (22), produces a sound when the displacement element (22) is moved. It is this sound that indicates that the push coupling connects the rudder correctly and that no leakage occurs. It may be advantageous for a sound to indicate that the sealing element (30) in the push coupling fulfills its function, as the push coupling can be placed in such a position that the fitters cannot see the push coupling. A sound is produced by moving the moving element (22) which thereby indicates that the sealing element (30) fulfills its function. In one exemplary embodiment, the displacement element (22) comprises a resilient part (24) which snaps over the element (26) when the displacement element (22) is displaced and thereby produces the sound. When the resilient part (24) is pressed over and past the element (26), the resilient part (24) snaps on and / or the element (26) snaps on and makes a sound. The element (26) together with the displacement element (22) produces a sound when the displacement element (22) is moved from the understood position to the other position. In one example, the displacement element (22) abuts the sealing element (30) and then the resilient part (24) clamps the displacement element (22) with the element (26) and / or the sealing element (30). When a rudder releases the displacement element (22), a sound is generated which indicates that the push coupling is tightening against the rudder which has been inserted into the housing (10). In an exemplary embodiment, the push coupling provides an audible confirmation that a movement of the displacement element (22) has taken place and that the sealing element (30) then has direct contact with a rudder in the push coupling and that the rudder is then fixed by the locking element (44). . It is then not possible for the rudder to be removed from the push coupling unless the locking element (44) is released. This year described further down. The push coupling ensures in this way that the rudder is correctly connected to the push coupling and that the correctly connected rudder remains correctly connected. In one embodiment, the push coupling comprises a displacement element housing (20). The displacement element (22) is axially displaceably arranged in the displacement element housing (20). The moving element housing (20) can prevent axial movement of the sealing element (30). The displacement element housing (20) is arranged in the housing (10) and may comprise a plurality of displacement elements (22). The transfer element housing (20) can be attached to the housing (10) by a positive fit. In an exemplary embodiment, the push coupling does not comprise a window, or similar opening, in the housing (10), e.g. when the window is arranged so that the moving element (22) is only visible through the window, the opening, when the moving element (22) is not in the understood position, illustrated in figure 1. The described embodiments have the advantage that the housing (10) does not need a window to indicate and secure the function of the push coupling. Windows lead to extra costs and an extra opportunity for leakage. Especially in cases where the sealing element (30) is only between, and has contact with, the outside of a pipe and the inside of the housing, as described above. In one embodiment, the push coupling includes a release member (42) arranged to release the locking member (44) by bending the locking member (44) radially outward. Through this, a rudder can be taken out of the push coupling. In an exemplary embodiment, the push coupling comprises a release element (42), a stand element (46), and a holder (48). The locking element (44) can be arranged between the standing element (46) and the holder (48). The locking element (44) can be held directly by the standing element (46) and the holder (48). The holder (48) can hold the release element (42) in the housing (10). The holder (48) and the release element (42) may be hooked together. When the rudder is to be removed from the push coupling, the release element (42) can be pushed in so that the locking element (44), its teeth, are released from the rudder. In an exemplary embodiment, the push coupling comprises two openings (12, 14) for each rudder, and the housing (10) may be I or L shaped. In one embodiment, the push coupling comprises three openings for each one rudder, and the housing (10) may be T-shaped. The housing of the push coupling (10) can be shaped to fit the rudders to be coupled. For example, a push coupling may be straight, I shaped, and such an embodiment is illustrated in Figures 1 and 2. This push coupling has two openings (12, 14) for each one rudder (60, 62). A similar push coupling can be angled, e.g. angular raw, L shaped. Such a push coupling has two openings for one rudder each. A push coupling can have e.g. three openings for each one rudder. Such a push coupling may be T-shaped and may comprise three parts of the housing (10) which are at a right angle to each other. As described above, all these lining examples have no window, that is to say the house has only openings for pipes to be connected. In an embodiment, push coupling can connect a rudder that can be guided along a surface (78) to a rudder that comes out from a surface (78), e.g. a cradle. These two rudders can be at a right angle to each other. Such an embodiment is illustrated in Figure 3. The push coupling may comprise a fastening device (76) for securing the push coupling to a surface (78). Such a surface can be e.g. a cradle. The fastening device (76) can e.g. be a plate that can be attached, e.g. screwed on a wall over a rudder that protrudes from the wall. The push coupling may comprise an opening (50) for a rudder from the surface (78). The opening (50) may be further away from the surface (78) than the center of the opening (12) away from the surface (78). This is illustrated in Figure 3. The opening (50) is at a distance D1 from the surface (78). The center of the opening (12) is at a distance D2 from the surface (78). The distance D1 is longer than the distance D2. The push coupling guides the flow (F) in the housing (10) through the push coupling, first out through the opening (50), and then back, towards the surface (78), out through the opening (12). The technical effect here is that the push coupling can connect a rudder to the opening (12) in the housing (10) so that the rudder is close to the surface (78) without the rudder having to bend, bend, down to a raw distance, 20 mm, from surface (78). The distance between a rudder that runs along a wall and the wall is usually predetermined, such as, for example, mainly 20 mm. Execution examples of the push coupling can ensure that the rudders have a raw distance to a surface, e.g. a cradle. In one embodiment, the push coupling includes a seal (52) for the housing (10) and a coupling (54) for the tube from the surface (78). The function of the seal (52) and the coupling (54) is to ensure that the push coupling connects to the rudder from the wall, from the surface (78). In one embodiment, the push coupling may include a valve (70, 72). As a result, the flow of a fluid through the push coupling can be shut off. The valve may be a ball valve (72) which may be opened or closed by means of a knob (70). A valve can be included in all described embodiments.
    A design example is a method for ensuring that the rudders have been connected correctly to a push coupling. The method includes the step of the push clutch producing a sound when the rudders have been properly connected to a push clutch. This allows the push coupling to confirm that a leak-free connection has been made. This means that the sealing element (30) has contact with, connects to, the rudder which is mounted with the push coupling. This is done audibly and no visual or mechanical control must be done. This is an advantage when, for example, the push coupling cannot be clearly observed, such as for concealed mounting in spring conduction systems and tap water systems, e.g. behind the wall or under the floor.
    An exemplary embodiment of the method is to use a push coupling as described above. All of the embodiments described herein can be used by this method to ensure that the rudders have been properly coupled to a push coupling.
