Description

[0001] The present invention relates to a synthetic material component which, for example, can be connected to a media supply line and by fastening elements can be connected to an object, on which the fastening elements can be secured in a hollow space. Furthermore, the invention relates to a synthetic material dispenser and a dispensing system.

[0002] At the technical level, distributors for line systems are known, which are used in particular in the case of pneumatic or hydraulic lines to supply a plurality of consumers from a source of media. These distributors are regularly used in motor vehicles. Generally speaking, distributors comprise a number of individual connector pieces which can be connected to each other and which can be reversibly fixed to a plate-shaped distributor bottom and correspondingly can be connected to a line of means. . DE 36 16 162 A1 describes a distributor of this kind for a line system, in particular the line system of a compressed air system for motor vehicles, with several outlets for lines, in particular flexible lines. The distributor comprises two distributing elements, each of which has at least one output and which can be plug-connected, with the outputs of the distributing elements communicating with each other through the plug-in connection.

[0003] WO 2006/077264 A1 describes a coupling device for hoses and/or piping, with two plate-shaped coupling parts that can be connected to each other and each has receiving openings for inserting and fixing parts of plug-in coupling, i.e. plug-in parts on the one hand, and socket parts on the other. Each coupling part has a receiving opening for a connector part and at least one receiving opening for a socket part, the receiving openings being arranged in pairs symmetrically about an axis of symmetry.

[0004] WO 01/65165 A1 discloses a device for removably connecting a pressure medium line to a pressure medium connection, with a connecting element that can be connected to the pressure medium line and with a device retaining device that can be secured to a housing by means of at least one fastening element.

[0005] To ensure that the synthetic material components are permanently screwed, it is necessary to ensure that there is no unacceptable reduction in the preload introduced by the application of the tightening torque due to accommodation phenomena. If the thread is part of the synthetic material component, the synthetic material thread may fail even at low tightening torques. This is especially true with smaller thread sizes. Furthermore, the applied torque can be almost completely dissipated over time due to the failure of the synthetic material.

[0006] Another additional problem at the level of the prior art is that the elements for attaching the synthetic material parts, for example, to a distributor plate, must stop at the synthetic material part and due to the available handling space, the bottoms can fall and possibly get lost.

[0007] The objective of the invention is to prepare a synthetic material component that allows simple attachment to an object and provides the option of not losing any attachment element.

[0008] The objective is achieved through the characteristics of claim 1. The preferred configurations are described in the dependent claims.

[0009] According to the invention, the objective is achieved by the fact that a synthetic material component is being prepared in which at least one fitting element is provided for connecting the synthetic material component to a line at least a coupling element for connecting the synthetic material component to another synthetic material component or to another line and a connecting element for detachably fastening the synthetic material component to an object, the connecting element having a hollow space in the end having a receptacle disposed in a hole for a fastening element, into which the fastening element can be inserted through an opening of the hollow space designed to be elastic, at least in some areas, in which the height of the opening is less to the fastening elements that can be inserted. The design of the synthetic material component according to the invention allows the fastening elements necessary for fastening to be introduced into the hollow space before the actual fastening. Due to the hollow space design, these will not fall out of the hollow space and are available for fixing. Hereby, the synthetic material components can also be attached to an object in different orientations, as it also does not fall even when the synthetic material component is rotated.

[0010] To simplify the introduction of the fastening means, the opening may have an insertion chamfer. The insertion chamfer can be formed by chamfering the areas of the connecting piece that form the opening.

[0011] In one configuration, the bottom of the connecting element that the receptacle presents can be designed to be spring elastic. This simplifies the compression of the base when screwed to a plate and a corresponding screw, so that a screwed connection between metal parts can be achieved. This allows the application of a sufficiently high preload and promotes the formation of a durable bolted connection.

[0012] In one configuration, the hollow space may be formed from a polygonal area that accommodates the receptacle and a dome-like area that extends axially in the direction of the fitting element. This design allows a form-fitting connection to be established between the cavity and a multi-edge fastener. Furthermore, insertion and removal of the fastener can be simplified by the dome-shaped cavity. Said dome-shaped cavity can also be used to receive a screw or its screw head when the screw is screwed into the cavity of the synthetic material component through the receptacle and the fastening elements.

[0013] Depending on the configuration of the fastening elements, it may be provided that the receptacle has a circumferential step on which the fastening means sits with its front face. In this regard, it is advantageous if the step has a polygonal inner surface that rests against a preferably polygonal outer surface of the fastening elements. This creates a positive connection and the torque can be transferred to the synthetic material component. Furthermore, due to the freedom of design of the receptacle, a large number of fasteners of different design can be introduced. The synthetic material component can thus be used universally for a variety of applications.

[0014] In order to present another connection possibility in addition to the first coupling element, it may be advantageous if the synthetic material component comprises a second coupling element that can be connected to another synthetic material component.

[0015] Furthermore, the invention relates to a synthetic material distributor with a synthetic material component as explained above and a fixing element, which is accommodated in the cavity of the connecting element. Due to the advantageous shape of the synthetic material component, a synthetic material distributor can be provided, which is supplied directly with fastening elements. This means that the fastening element is inserted into the synthetic material component through the cavity after its production and the distributor can then be packaged and delivered. Due to the shape of the cavity, the fastening element cannot fall out of the cavity. The preferred synthetic material component configurations explained above can also be applied to the synthetic material distributor.

[0016] Preferably, the fastening elements are designed as a polygonal metal nut with an internal thread. A screw made of polygonal synthetic material can also be used. However, it has been found that for a number of applications, the use of a metal polygonal nut can achieve a high quality threaded connection. When using the polygonal nut, it can tilt into a multi-edged cavity or a multi-edged receptacle so that a form-fitting connection can be achieved.

[0017] It may be provided that the polygonal nut has a cylindrical collar that is disposed at the end and has an external diameter smaller than that of the polygonal nut, which collar can be introduced into the orifice receptacle. Due to the collar, the nut has two different outer diameter ranges. The diameter of the receptacle can be designed so that only the smaller diameter can be introduced into the receptacle, so that the area with the larger diameter rests with its front face on the bottom of the cavity. This ensures that the polygonal nut and the synthetic material component can be connected to each other without play and in a tight manner.

[0018] In one configuration, the height of the fastener or the length of the collar may be less than or equal to the thickness of the bottom wall of the connecting element, so that the bottom side of the fastener is essentially flush with the bottom. . If the synthetic material distributor is attached to an object, such as a plate, for example, this can ensure, on the one hand, that the synthetic material component can be attached to the object without play. On the other hand, impermissible deformation of the synthetic material body can be avoided and the metal components can be screwed together. Due to the shape, the lower part of the synthetic material component can be easily compressed by screwing a screw into the fastening element until the end face of the fastening element, for example, comes to rest on a plate.

[0019] Depending on the shape of the fastening element, the synthetic material component can be designed so that the receptacle has a step to receive the fastening element. For example, the step may be designed as a partially or fully circumferential step, i.e. in the form of a ring, within the receptacle in which a fastening element sits with its front face. In this regard, it may be advantageous if the receptacle has a polygonal configuration, at least in some areas, that is, that the step has polygonal inner surfaces that are designed to rest on polygonal outer surfaces of the fastening elements.

[0020] The invention also relates to a distributing system comprising a plurality of synthetic material components or synthetic material distributors and an object with holes for fixing the synthetic material components, the synthetic material components being able to be fixed to the object by means of fastening elements and being fluidly connected to one another through coupling elements with at least one fitting element of a synthetic material component with a media supply line and several elements fitting of other synthetic material components that are connected to consumers. The shape of the synthetic material component allows the formation of a distribution system in which the individual synthetic material components are simply connected to each other. Furthermore, each synthetic material component can be secured to the board simply and securely with the fastening elements. The previously explained preferred configurations of the synthetic material component and the synthetic material distributor can also be applied to the distributor system.

[0021] Next, the invention is explained in more detail using an example configuration of the invention, which is illustrated in the drawing. The figures present:

[0029] Figure 7: several elements coupled and fixed to a board of synthetic material components and

[0030] Figure 8: an enlarged sectional view of a synthetic material component according to figure 7.

[0031] Figure 1 shows a sectional representation of a synthetic material component and Figure 2 a side view of the synthetic material component. The synthetic material component 1 comprises at least one fitting element 2 for connecting the synthetic material component 1 to a line (not shown), a coupling element 3 for connecting the synthetic material component 1 to another synthetic material component 1 and a connecting element 4 for detachably fastening the synthetic material component 1 to an object 5 (see Figure 7). The synthetic material component 1 can be produced in a single piece by an injection molding process. In the represented form of configuration, the fitting element 2 and the connecting element 4 are essentially opposite each other in the longitudinal axis 6 of the synthetic material component 1, in which the coupling element 3 is arranged centrally between both elements 2, 4 and transversely to the longitudinal axis 6.

[0032] The fitting element 2 has an axial axis along the longitudinal axis 6 that extends through the orifice 7 and can be connected to lines, such as, for example, pressure lines for gaseous or liquid media. To this end, the connecting end 8 may have, for example, rib-shaped or wedge-shaped elevations 9, which are at least partially arranged on the surface of the connecting end 8, so that a connection is achieved. non-positive between the connector on part 2 and the line. The elevations 9 may be present circumferentially on the surface and may be arranged parallel or non-parallel to each other. The end of the connecting element 8 can be designed in a conical shape to simplify insertion of the connecting element 2 into a pipe, for example into a pipe made of synthetic material. Additional means may be provided for reversibly attaching or securing the line to the fitting element 2. The same applies to seals, which may be present in grooves in the connecting end 8, which are not shown, if necessary.

[0033] The first coupling element 3 arranged transversely to the longitudinal axis 6 has a through hole 10 and is fluidly connected to the fitting element 2. The coupling element 3 is designed as a fitting element 11 or sleeve 12, as necessary, and is used to connect the synthetic material component 1 to an adjacent synthetic material component 1, which has the appropriate coupling part 3 to establish a fluid connection. In the illustrated form of configuration, the coupling element 3 is configured as a fitting element 11 with a circumferential step 13 into which, for example, the retaining elements of a suitable socket can reversibly engage or which serves to accommodate an O-ring. . Alternatively, the coupling element 3 can also function as a kind of plug-in element and can be used to connect to another line.

[0034] Furthermore, the represented configuration also presents a second coupling element 3 which is arranged, for example, diametrically in relation to the first coupling element 3 and is designed as a sleeve 12. The arrangement of the second element of coupling 3 with respect to the first coupling element 3 is obviously based on the intended use of the synthetic material component 1. Depending on the application, the coupling elements 3 can also be positioned at a different angle to each other. The second coupling element 3 also has a through hole 10, so that both coupling elements 3 are fluidly connected to each other and to the through hole 7 of the fitting element 2. Furthermore, the invention expressly also includes solutions in which the synthetic material component 1 has only a coupling element 3 and this coupling element 3 is designed as a plug-in element 2 for connection to a fluid line.

[0035] The connecting element 4 is arranged opposite the fitting element 1, through which the synthetic material component 1 can be detachably attached, for example, to an object 5, such as a distributor or a support plate. . The connecting element 4 has a cavity 14 that is molded on three sides of the connecting element 4 or its walls and is accessible from one side. This means that a wall of the connecting element 4 is designed as an opening 15 or an access to the hollow space 14. The hollow space 14 can be polygonal in shape, for example it can be rectangular. A dome-shaped area 17 may be provided above the polygonal area 16 as an extension of the polygonal hollow space 16. A step may be provided between the polygonal area 16 and the dome-shaped area 17, which extends from the rear wall of the hollow space 14 in the direction of the opening 15, that is, almost transversely axially to the longitudinal axis 6 of the synthetic material component 1 and in the front third close to the opening 15 in the direction of the fitting element 2 it presents an inclination in the direction of the fitting element 2. The opening 15 is widened by the inclination, in particular in the direction of the polygonal hollow space 16. The inclination functions as a kind of insertion chamfer 18.

[0036] At least one area forming the opening 15 is designed to be elastic. For example, this may be a rib 19 at the bottom of the hollow space 14, i.e. the end of the connecting element 4 which is opposite the fitting element 2 along the longitudinal axis 6. Thereby the opening 15 may be reversibly stretched by force and increased in width.

[0037] At the bottom 20 of the hollow space 14 there is a hole designed as a receptacle 21 and, in particular, of cylindrical shape. The receptacle 21 may have a circumferential step (not shown) as a narrowing of its diameter. In this form of configuration, the receptacle 21 may also be polygonal, so that its internal surfaces are polygonal. Alternatively, the receptacle 21 may also be designed in a continuous manner. The receptacle 21 may be arranged coaxially to the longitudinal axis 6.

[0038] Figures 3A, B show a bottom view and a sectional view of a configuration of a fastening element. The fastening element 22 may be a polygonal metal nut, for example, be designed as a square metal nut and have an internal thread. The fastening element 22 is provided with a cylindrical collar 23 or collar fixed on one side. The collar 23 means that the fastening element 22 has a step and therefore has two different external diameters. In one form of configuration, the fastening elements 22 can also be used with or without collar 23, in particular, for the form of configuration of the receptacle 21 with a step on which the fastening elements 22 can rest with their front face.

[0039] Figure 4 shows a sectional representation of the synthetic material component when introducing the fixing element into the hollow space of the connection element, figure 5 shows an enlarged view of the connection element according to figure 4 and figure 6 shows an enlarged view of the connecting element with a fastening element in the receptacle. An internally threaded fastener 22 may be introduced into the hollow space 14 through the opening 15 and placed in the receptacle 21 such that the internal thread is oriented essentially coaxially with the receptacle 21 and the longitudinal axis 6 of the material component. synthetic 1. Thereby, the thread points in the direction of the hole forming the receptacle 21 and can be connected, for example, to a screw screwed into this hole. The nominal width of the fasteners 22 is basically specified by the nominal width of the receptacle 21. Preferably, the fastener 22 is designed so that its height is greater than the width of the hollow space 14 opposite the receptacle 21. Furthermore , the height of the fixing element 22 may be greater than the dimension of the opening, that is, than the opening height of the opening 15 itself. Due to the elastic property of the opening 15, which is formed, at least in areas, the opening 15 may be slightly larger, but sufficient when the fixing element 22 is inserted, and the insertion chamfer 18 may facilitate insertion. As soon as the collar 23 or the lower edge of the fastening element 22 passes the edge of the receptacle 21, the fastening element 22 engages the receptacle 21 and the opening area 15 is designed to spring back into its initial position. In this position, the fastening elements 22 and their internal thread are coaxial with the receptacle 21 and coaxial with the longitudinal axis 6 of the synthetic material component 1.

[0040] It may be advantageous if the fastening element 22 has a collar 23 so that the fastening element 22 is in the area with the smallest external diameter in the receptacle 21 and the area with the collar 23, i.e. the largest diameter, rest in the receptacle 21. The fixing element 22 is fixed radially in its current position in the hollow space 14, but can be moved slightly axially. However, the axial mobility of the fastening elements 22 does not have a negative influence on the screwdriving behavior, since the fastening elements 22 cannot move radially. Radial fastening can be advantageously achieved by the fact that the fastening elements 22 have several edges, for example, are designed as a square nut, and the external surfaces of the fastening element 22 to create the internal surfaces of the polygonal portion 16 of the space. hollow 14.

[0041] In another configuration, which is not shown, the fastening element 22 does not have a collar 23, but instead rests on a step of the receptacle 21 after being inserted through the opening 15 as described above. Here too, the fixing element 22 is fixed radially, but can move slightly axially in the receptacle 21. In this regard, it is advantageous that the receptacle 21, in particular the step on which the fastening element fixture 22 rests, is designed with multiple edges, so that the fixture 22 which is particularly polygonal in shape, rests with its outer surfaces on the inner surfaces of the receptacle step 21.

[0042] In a particularly preferred form of configuration, the introduced fastening element 22 is essentially flush with the bottom 20 of the connecting element 4. It is particularly advantageous if the fastening element 22 does not project beyond the edge of the base. 20. This means that the height of the fastening elements 22 and the length of the collar 23 are preferably dimensioned so that they are below the height of the bottom 20 of the connecting element 4.

[0043] The dome-shaped hollow space 17 above the polygonal hollow space 16 can be used to insert a tool to thereby move the fastening elements 22 into the hollow space 14 or to remove them from the hollow space 14 of the synthetic material component 1.

[0044] Figure 7 shows several synthetic material components coupled together and fixed to a plate, and figure 8 shows an enlarged sectional representation of a synthetic material component according to figure 7. Various synthetic material components Thetic device 1 can be fixed to an object 5, for example, a plate provided with holes, and thus form a distribution system. Each of the individual synthetic material components 1 is fluidly connected to each other via coupling elements 3. This is advantageous, for example, when one of the synthetic material components 1 with its fitting part 2 is fluidly connected fluid to a feeding line of media and other synthetic material components 1 with their fitting parts 2 to different consumers, so that the consumers can be fed with the media in a simplified manner. The arrangement and number of synthetic material components 1 may vary depending on the configuration of the object 5 and as necessary.

[0045] The synthetic material component 1 can be fixed with its connecting element 4 on the object 5, for example, the plate. After the fastening element 22 is placed in the receptacle 21, the synthetic material component 1 can be positioned with the receptacle 21 above a hole present in the object 5. It may also be advantageous if the synthetic material component 1 is already supplied with the fixing element 22 in the hollow space 14, that is, the fixing elements 22 can already be inserted during production. Due to the fact that the fastening elements 22 cannot fall out of the hollow space 14, the risk of losing the fastening elements 22 during transport or during assembly is low or non-existent.

[0046] When screwing the synthetic material component 1 to the object 5, that is, by fixing a screw 24 from below through the hole in the object 5 on the internal thread of the fastening element 22, the end face of the fastening element 22, in particular , the collar 23 is first placed in contact with the bottom 20 in the hollow space 14, in particular, the receptacle 21 or the one used in the present step. This is then especially the case when the fastening element 22 is axially displaced. When fixing the fixing element 22 it is precisely aligned. The applied tightening torque is transmitted to the synthetic material component 1 through a positive connection between the outer surfaces of the fastening elements, in particular, multi-edge fasteners 22 and the multi-edged hollow space 16.

[0047] Further tightening of the screwed connection can cause the lower bottom 20 of the connecting element 4 to be pressed, in particular, until the front face of the collar 23 is thus in contact with the threaded face of the object 5. In this case, the screw head 24 here moves upward into the dome-shaped area 17 of the hollow space 14.

[0048] The permitted deformation of the bottom 20 of the connecting element 4 does not result in any damage to the function of the synthetic material component 1. On the contrary: this deformation can be planned by sizing the bottom 20 accordingly, for example by sizing the thickness of the bottom 20 so as not to be exceeded by the length of the fixing elements 22 or the collar 23. Furthermore, a malleable synthetic material may be provided for the bottom 20 or for the connecting element 4 as a whole.

[0049] The advantage of this configuration is that impermissible deformation of the synthetic material component 1 is avoided and the metal components can be screwed together, i.e. between the fastening elements 22 and the object 5. In this way, it can be achieved a sufficiently high prestress of the connection, which is not reduced by the creep of the synthetic material. Furthermore, the permissible adjustment of the synthetic material component 1 ensures that the fastening elements 22 and the synthetic material component 1 are positively connected to each other without any gaps. Another advantage lies in the fact that the screwed connection is reversible and the components are not damaged, i.e. they can be reused. Especially since no loss of the fastening element 22 is possible, even when loosening the screw connection.
