Description

[0001] This application is a divisional application of the application filed on September 12, 2017, with application number 201780056360.5 (international application number PCT / DE2017 / 000295) and entitled "Detachable faucet with spring element for fixing and preloading". Technical Field

[0002] This invention relates to a tap for forming a fluid connection between at least two connector components and for disconnecting the fluid connection. Therefore, the tap is preferably designed to be detachable or disassembleable. Background Technology

[0003] Faucets for forming fluid connections are known from the prior art. For example, publication EP0863340A2 discloses a faucet having a housing and a rotatable stopcock within the housing, the stopcock being supported by a sealing surface against a sealing surface of the housing in its operating position, and being movable from the operating position to an intermediate position (b) when the detachable connection between the stopcock and the housing is released, in which the sealing surfaces are not in contact and the housing and the stopcock remain connected. Thus, the stopcock is locked to the housing in a form-fitting and reliably locking manner, and can be moved to the intermediate position when this locking is overcome.

[0004] Especially in the biological and medical fields, it is essential to ensure that faucets that can be used in multiple ways can be easily disassembled for cleaning by rinsing and for disinfection, where assembly and disassembly of the faucet should be possible and easy. Furthermore, such faucets should preferably be able to be manufactured at low cost. Summary of the Invention

[0005] Therefore, the object of the present invention is to create a preferably detachable faucet that can be easily assembled and disassembled and is therefore inexpensive.

[0006] According to the invention, the previously mentioned task is achieved by means of a faucet as described in the main technical solution of the invention. The faucet according to the main technical solution of the invention preferably comprises at least: a connecting and disconnecting element for forming a fluid connection and for disconnecting the fluid connection; a manual actuating element for rotating the connecting and disconnecting element; and a body. Thus, the connecting and disconnecting element is at least partially tapered and includes at least one channel opening for forming the fluid connection, wherein the manual actuating element and the connecting and disconnecting element are mechanically connected. Preferably, the manual actuating element and the connecting and disconnecting element are elements of a single device, thus always connected to each other.

[0007] The body includes at least one connector component, and preferably multiple or all connector components, and an internal space for receiving connecting and disconnecting elements, wherein the internal space includes contact surfaces for contacting the connecting and disconnecting elements, wherein the contact surfaces have at least a partial female configuration relative to the tapered surface component of the connecting and disconnecting elements. According to the invention, at least one spring element is provided for form-fittingly fixing the position of the connecting and disconnecting elements relative to the body, and preferably for generating surface pressure and / or for fixing the contact surface between the contact surface and the tapered surface component of the connecting and disconnecting elements. Therefore, the spring element is preferably arranged in or on the body. Furthermore, the connecting and disconnecting elements for disassembly or assembly are movable relative to the spring element along the axial extension direction of the connecting and disconnecting elements.

[0008] This solution is advantageous because it provides a simple and therefore inexpensive arrangement in which the spring element provides the positioning and fastening of the connecting and disconnecting elements relative to the body. This results in good assembly and disassembly capabilities.

[0009] Other embodiments are dependent technical solutions in this invention and are the purpose of the following description.

[0010] According to a preferred embodiment of the invention, the connecting and disconnecting element includes an extension that is supported against a tapered portion having a minimum diameter in the axial extension direction of the connecting and disconnecting element. The extension includes a wall, which may be circumferential and preferably inclined in the axial extension direction. At least one spring element or at least one fixing tool acted upon by the spring element contacts the wall to generate tension within the connecting and disconnecting element, preferably to generate surface pressure between the contact surface and the tapered surface component of the connecting and disconnecting element. This embodiment is advantageous because, specifically, a sealing effect is created between the connecting and disconnecting element and the body due to the interaction between the inclined wall and the spring element or the fixing tool. Here, the sealing effect can be influenced by various levels of spring force. The preferably circumferential wall inclined in the extension direction is preferably inclined such that the tapered surface and the inclined wall are oriented towards each other at an angle less than 180°, particularly less than 178°, less than 175°, less than 170°, or less than 165°. However, additionally or as an alternative, sealing devices, such as O-rings, may be provided to seal the connecting and disconnecting elements against the body. Preferably, multiple sealing devices are provided, and more precisely, two sealing devices are provided, for sealing the connecting and disconnecting elements relative to the body.

[0011] According to another preferred embodiment of the invention, the spring element comprises at least two elongated components, wherein the two elongated components are connected to each other by means of a bent component, wherein the two elongated components are designed as two preferably straight elongated positioning components, and the two elongated components contact a preferably inclined circumferential wall to generate tension within the connecting and disconnecting elements, preferably to generate surface pressure between the contact surface and the tapered surface component of the connecting and disconnecting elements. This embodiment is advantageous because the spring element can be easily manufactured and the positioning components can be pressed apart from each other for assembly or disassembly. Furthermore, the spring or spring element also secures the position of the connecting and disconnecting elements by initially having to overcome the spring force during disassembly.

[0012] According to another preferred embodiment of the invention, the spring element additionally includes at least two elongated, preferably straight, retaining members, wherein the elongated retaining members form the ends of the spring element and are coupled to the body in a form-fit or friction-lock manner, and wherein each positioning member is connected to the retaining member via a bending member. Thus, the spring element preferably forms an M-shape, wherein the wrap angle of the radius of the bending member connecting the two positioning members is smaller than the wrap angle of the radius of the bending member connecting the retaining member to the positioning member. Preferably, the radius of the bending member connecting the two positioning members is at least 1 mm, at least 2 mm, or at least 3 mm larger than the radius of the bending member connecting the retaining member to the positioning member. This embodiment is advantageous because the positioning members can reliably contact the connecting and disconnecting elements, and the retaining member and / or the other bending member results in the generation of spring force and / or fixation of the spring element to the body. Furthermore, this embodiment is advantageous because the retaining member forms a significant area for support on the body, and the force transmitted to the spring via the connecting and disconnecting elements when the connecting and disconnecting elements are rotated is reliably transmitted to the body.

[0013] According to another preferred embodiment of the invention, the bending member includes portions with different radii, wherein the main portion has a radius greater than the radii of the two auxiliary portions, and wherein the positioning member is connected to the main portion via the auxiliary portions. This embodiment is advantageous because the spring element can be manufactured in an inexpensive manner, and due to the considerable number of bending portions (auxiliary portions and main portion), the required spring force is reliably provided to form the necessary pressure between the connecting and disconnecting element and the body. Preferably, if any spring element is mentioned herein, it always relates to a spring element made of metal, plastic, or composite material.

[0014] According to another preferred embodiment of the invention, the spring element additionally includes at least three elongated retaining members, wherein positioning members form the ends of the spring element, wherein each positioning member is connected to a retaining member via a bending element, wherein the central elongated retaining member is connected to one of the other retaining members on each side via two bending elements, wherein the retaining elements are coupled to the body in a form-fit or friction-lock manner. Preferably, the retaining members connected to each other via bending elements are oriented toward each other at an angle between 70° and 110°, preferably at an angle of 90°. This embodiment is advantageous because, due to the three elongated, preferably straight, retaining members, even more contact possibilities for force transmission can be obtained. Therefore, even during the rotation of the handle by the user pulling the handle, the tapered contact area seals between the connecting and disconnecting elements and the body.

[0015] According to another preferred embodiment of the invention, two spring elements are provided, preferably at least two, or precisely two or at most two spring elements. Additionally, it is conceivable that each spring element includes an elongated, more preferably straight, retaining member and an elongated, more preferably straight, positioning member, wherein the retaining member and the positioning member are each connected to each other by means of a curved member. Thus, the positioning member preferably partially contacts a wall, which is preferably at least partially inclined and preferably wholly or partially circumferential, to generate tension in the connecting and disconnecting elements, and preferably to generate surface pressure between the contact surface and the tapered surface member of the connecting and disconnecting elements. Thus, the elongated retaining member is coupled to the body in a form-fit or friction-locking manner, wherein the positioning member, each having an end spaced apart from the curved member, interacts with the body in a form-fit manner, and wherein pin members are respectively abutted against the retaining member, extending orthogonally toward the horizontal plane spanned by the positioning member and the retaining member, wherein each pin member is respectively inserted into a drilled hole or recess in the body. This embodiment is advantageous because the spring element and the retaining element designed to hold the spring element can be constructed to be very thin and small relative to other structural forms, thereby resulting in savings in material and weight.

[0016] According to another preferred embodiment of the invention, the body includes a spring guide for receiving a spring element, wherein the spring element includes a curved portion, the spring element being connected to the spring guide by means of the curved portion, wherein the curved portion is part of a curved member that at least substantially encloses the body in the circumferential direction, and preferably encloses the body at an angle greater than 270°, wherein, on one hand, the curved portion forms a fastening member connected to the body or a fixing tool, and on the other hand, another curved member is adjacent to the curved member, wherein the other curved member and the curved member are spaced apart from each other by an elongated, preferably straight member, and wherein the other curved member and the straight member are at least substantially surrounded by the curved member. This embodiment is advantageous because, by means of the spring element, pressure acting on the connecting and disconnecting elements can be generated very precisely. Furthermore, the spring element can be arranged very easily on the body.

[0017] According to another preferred embodiment of the invention, the spring element forms a fastening member that extends elongatedly, more preferably in a straight line, and is designed to be inserted into a recess designated for the fastening member or a receiving area of ​​the body designated for the fastening member, wherein a power transmission member abuts the fastening member, and wherein, by means of the power transmission member, the fixing element is subjected to a clamping force in the direction of connecting and disconnecting the element. This embodiment is advantageous because the fixing element can be added and designed in a very precise manner, and more preferably, the fixing element can preferably have a geometry adapted to a preferably inclined wall and / or be made of a defined material or can be coated.

[0018] According to another preferred embodiment of the invention, a plurality of fixing tools are provided, each of which is radially movable via a guide portion designed into the main body, and the fixing tools can be pressed toward each other by means of spring elements. This embodiment is advantageous because the fixing elements can be introduced in a very precise manner, for example, from two opposite sides. Furthermore, the fixing elements can preferably be formed, specifically having a geometry adapted to an inclined wall and / or made of a defined material or can be coated.

[0019] According to another preferred embodiment of the invention, the faucet can be disassembled non-destructively into at least the following components: connecting and disconnecting elements, spring elements, and a body. This solution is advantageous because worn parts can be easily replaced and / or cleaning and / or disinfection of individual or all parts can be initiated.

[0020] The connecting and disconnecting elements can be specifically designed as plugs or pistons.

[0021] According to another preferred embodiment, the spring element is made of a bent wire.

[0022] According to another preferred embodiment of the invention, a plurality of spring elements with the same structure, more preferably, two or three spring elements with the same structure.

[0023] According to another preferred embodiment of the invention, at least three identical spring elements are provided, wherein each spring element is rotatably mounted in a recess about a rotation axis at one end and is held in a form-fitting manner by a retaining element at the other end in the extension direction of the rotation axis.

Therefore, the spring element 34 comprises two parts 50, 52, which preferably extend in an elongated manner, more preferably in a straight line, and according to the invention, the two parts 50, 52 are intended to be supported on the connecting and disconnecting element 6 (e.g., see...). Figure 2 II.), to generate tension within the connecting and disconnecting element 6. Therefore, the component preferably extending in a straight line may also be referred to as the first positioning component 56 and the second positioning component 58. The two positioning components 56, 58 are connected to each other via a bending component 54. The ends of the bending component 54 and the spring element 34 can preferably be joined to the body 12 in a form-fit manner (e.g., see...).

[0040] With diagrams I.-V. Figure 2 Different views and components of exemplary embodiments of the present invention are shown.

[0041] exist Figure 2 In Figure I, the detachable faucet 1 is shown in an assembled or installed state. Clearly, the faucet 1 includes a body 12, which includes at least one first connector component 2 and a second connector component 4. Here, connector components 2 and 4 can be designed to be the same or different. A manual actuation element 10 is inserted into the body 12. The manual actuation element 10 is used to rotate the connecting and disconnecting element 6, wherein the manual actuation element 10 and the connecting and disconnecting element 6 are mechanically connected, and more preferably, the manual actuation element 10 and the connecting and disconnecting element 6 are made as a single piece. Therefore, preferably, the connecting and disconnecting element 6 is considered as an integral part of the manual actuation element 10. The manual actuation element 10 preferably also forms a handle component 26, which preferably extends orthogonally in a lever-like manner toward the longitudinal extension direction of the connecting and disconnecting element 6. Furthermore, reference numeral 24 indicates an extension that preferably extends from the body 12 and, therefore, is preferably at least partially not surrounded by the body 12 in the circumferential direction.

[0042] Figure 2 II. A faucet 1 in a disassembled state according to the invention is shown. It is evident that the connecting and disconnecting element 6 includes a channel hole 8. Therefore, in the illustrated orientation, Figure 2The channel hole 8 in section I connects the first connector component 2 and the second connector component 4, thereby allowing fluid, particularly liquid or gas, to be guided from one connector component to the other. An extension 24 is arranged on one side of the connecting and disconnecting element 6, on which the tapered portion formed by the connecting and disconnecting element has a minimum radius 22, thus meaning it is arranged on the side opposite to the handle component 26. Reference numeral 11 indicates the base of the manually actuated element 10, wherein the handle 26 is mechanically connected to the connecting and disconnecting element 6 via the base 11, more specifically, the connection is a single piece. Furthermore, reference numeral 14 indicates the internal space formed by the body 12, which is designed to receive the connecting and disconnecting element 6.

[0043] Figure 2 III. A plan view of the lower side of the faucet 1 in its assembled state according to the invention is shown. It is thus apparent that the spring element 34 also includes at least two elongated components 50, 52. The two elongated components 50, 52 are preferably designed as two elongated positioning components 56, 58, and specifically, the two elongated components 50, 52 are preferably connected to the wall 40 (see...). Figure 2 IV.) Contact to generate tension in the connecting and disconnecting element 6, thereby preferably generating surface pressure between the contact surface 16 and the tapered surface component 28 of the connecting and disconnecting element 6. Furthermore, the spring element 34 additionally includes two elongated retaining members 60, 62, wherein the elongated retaining members 60, 62 form the ends of the spring element 34 and are coupled to the body 12 in a form-fit or friction-locking manner.

[0044] Here, each positioning member 56, 58, preferably extending in a straight line, is connected via a bending member 64, 66 to a retaining member 60, 62, preferably extending in a straight line.

[0045] Figure 2IV. A cross-sectional view is shown through the assembled faucet 1 according to the invention. Thus, the spring element 34 is supported against the wall 40, which is preferably inclined toward the extending direction A of the connecting and disconnecting element 6 and particularly preferably circumferential, and the spring element 34 introduces force into the connecting and disconnecting element 6 via the wall 40. The introduced force generates tension in the connecting and disconnecting element 6. Due to the tension, the tapered surface part 28 of the connecting and disconnecting element 6 is pressed against the contact surface 16 of the body 12, which has a preferred female configuration relative to the tapered surface part 28. In the preferred embodiment described herein, the inclination of the tapered surface of the connecting and disconnecting element 6 toward the longitudinal extending direction A of the connecting and disconnecting element 6 is between 1° and 10°, preferably between 2° and 8°. The upper end of the body 12 is indicated by reference numeral 32, and the lower end of the body 12 is indicated by reference numeral 30. Therefore, the connecting and disconnecting element 6 is inserted into the body 12 in the region of the upper end 32, and then, preferably, partially emerges from the body 12 in the region of the lower end 30. The outer surface of the body 12 is indicated by reference numeral 19. The body 12 is preferably made of metal, particularly steel or plastic, or comprises metal or plastic.

[0046] Figure 2 V. shows an example of an alternative manual actuation element 10 that can be used as an alternative. Here, the opening 8 must not be designed as a straight channel opening, but can extend in the longitudinal direction A from the tapered circumferential wall of the connecting and disconnecting element 6, and thus fluid can be supplied or discharged via the connector part 5 arranged or formed on the manual actuation element 10.

[0047] Figure 3 Figure 1 shows a schematic diagram of the lower side of the faucet 1 in an assembled state according to the invention. According to this figure, a spring element 34 is used, which includes two positioning parts 56, 58 oriented at an angle toward each other.

[0048] Spring element 34 additionally includes at least three elongated, more preferably straight, retaining members 60, 62, 74 (see [link to relevant documentation]). Figure 3II.) Positioning members 56, 58 form the ends 76, 78 of the spring element 34 and preferably extend in a straight line. Thus, each positioning member 56, 58 is connected to the retaining members 60, 62 via bending members 64, 66, wherein the central elongated retaining member 74 is connected on either side to one of the other retaining members 60, 62 by means of two bending members 54, 55. The retaining members 60, 62, 74 are coupled to the body 12 in a form-fit or friction-locking manner. The body 12 additionally includes retaining elements 92, 94, 96. Thus, each retaining element 92, 94, 96 forms at least one recess to provide at least one contact surface, on which the bending portions 54, 55, 64, 66 and / or the retaining members 60, 62, 74 are supported in the extending direction A of the connecting and disconnecting elements 6.

Thus, spring element 34 is formed in an M-shape, wherein the radius of the bending member 54 connecting the two locating members 56, 58 is larger than the radius of the bending members 64, 66 connecting the retaining members 60, 62 to the locating members 56, 58.

The retaining members 60, 62 are preferably coupled to the body 12 in a form-fit or friction-locking manner, more preferably via a method preferably similar to... Figure 3 The retaining elements 92, 94, and 96 formed in the embodiment are connected to the body 12.

Therefore, the third retaining element 96 forms a covering protrusion or the first retaining tab 104 and the second retaining tab 106, which interact with the ends 76, 78 of the spring element 34, specifically in a form-fitting manner.

[0064] Alternatively, the third retaining element 96 may include one or more recesses 102, more preferably two or at least two, or precisely two or three, or at least three or precisely three. The at least one recess 102 preferably extends from the outer surface of the body 12 into the internal space 14 of the body 12. The recess 102 is preferably designed such that the spring element 34 can enter via the recess 102.

[0065] Therefore, it is particularly preferred that the third retaining element 96 includes two retaining tabs 102, 104 and two recesses 102.

[0066] Figure 10 It shows Figure 5A variation of the embodiment shown is described. According to this embodiment, two identical spring elements 34 can be used. Preferably, each spring element 34, 35 is held to the body 12 by means of drill holes or recesses 84, 88 and two retaining elements 92, 94 and 96, 97, respectively. Therefore, the relative positions of the first drill hole 34, the first retaining element 92, and the second retaining element 94 preferably correspond to the relative positions of the second drill hole 88, the third retaining element 96, and the fourth retaining element 97. Preferably, the first spring element 34 is arranged in a position rotated 180° relative to the second spring element 35.

[0067] Figure 11 Another preferred embodiment of the invention is shown, wherein three spring elements 34, 35, and 36 are provided. The structures of each spring element 34, 35, and 36 are preferably identical. Furthermore, the spring elements 34, 35, and 36 are preferably arranged in a recess or bore 84 via a first end 76, and interact with retaining members 92, 94, and 96 via a second end 78, specifically in a form-fit manner. Preferably, two spring elements 34, 35, and 36 are each retained in a form-fit manner by each retaining element 92, 94, and 96. Furthermore, the relative position of the first recess or bore 84 with respect to the first retaining element 92 and the third retaining element 96 corresponds to the relative position of the second recess or bore 88 with respect to the second retaining element 94 and the first retaining element 92, and / or the relative position of the third recess or bore 89 with respect to the third retaining element 96 and the second retaining element 94.

[0068] Figure 11 II. Shown Figure 11 The arrangement shown in I. is without retaining elements 92, 94, and 96. Figure 12 I.and Figure 12 The implementation shown in II is essentially the same as Figure 11 I.and Figure 11 Corresponding to the embodiment shown in II, spring elements 34, 35, and 36 are designed for line contact with the connecting and disconnecting element 6. Therefore, spring elements 34, 35, and 36 include a bent positioning member 59 located between the second end 78 of the spring elements 34, 35, and 36 and the bending member 54. This embodiment is advantageous because a larger contact area is formed between the spring elements 34, 35, and 36 and the connecting and disconnecting element 6, thereby allowing a greater force to be transmitted between the spring elements 34, 35, and 36 and the connecting and disconnecting element 6.

[0069] Therefore, the present invention relates to a faucet 1 for forming and disconnecting a fluid connection between at least two connector components 2, 4. The faucet according to the invention comprises: a connecting and disconnecting element 6; a manual actuating element 10 for rotating the connecting and disconnecting element 6, wherein the manual actuating element 10 and the connecting and disconnecting element 6 are mechanically connected; a body 12 having connector components 2, 4 and an internal space 14 for receiving the connecting and disconnecting element 6, wherein the internal space 14 has a contact surface 16 for contacting the connecting and disconnecting element 6, wherein the contact surface 16 has at least a partial female configuration relative to the tapered surface component 28 of the connecting and disconnecting element 6; wherein at least one spring element 34 is provided for form-fittingly fixing the position of the connecting and disconnecting element 6 relative to the body and for generating surface pressure between the contact surface 16 and the tapered surface component of the connecting and disconnecting element 6, wherein the spring element 34 is arranged in or on the body 12, and the connecting and disconnecting element 6 is movable relative to the spring element 34 in an axial direction for disassembly or assembly.
