Definitions

  • the present invention relates to a variably adjustable branched pipe-joint fitting of the kind set forth in the preamble of claim 1.
  • V7hen connecting drain pipes it is known to use pipe joints of the type muff couplings, in which two pipe ends, of which one is straight and smooth and the other is provided with a muff with an inserted sealing ring embracing its pipe part, are pushed together.
  • pipe joints in which two pipe ends, one having a thread and the other a union nut, are screwed together.
  • both these types of pipe joints require that the pipes are separate or can be held separate from each other with a certain spacing and partly that they are held with their central axes generally parallel and in im- mediate continuation of each other, partly that their end surfaces are held substantially parallel to ⁇ •each other.
  • the threaded joint does not allow any possibility of variable adjust- ment, whether it be before, during or after the instal ⁇ lation work.
  • Branched pipe-joint fittings consisting of a main pipe component and at least one branch pipe component are
  • the object of the present invention to provide a variably adjustable branched pipe-joint fitting of the kind referred to initially, in which the continuously variable adjustable angle ⁇ between the main pipe and at least one branched pipe can lie between 0° and 180°, but preferably lies between 45° and 90°, at the same time maintaining a substantially uniform and constant internal flow cross-section for the liquid being transported.
  • the invention should provide facilities for translation and rotation of the main pipe in and about its longitudinal direction with simultaneous rotation of at least one branch pipe, this in connection with the assembly of the branch fitting with its associated drain pipe pieces provides a far greater number of possibilities for adaptability during the installation work, also fa ⁇ cilitating the latter, and also reducing the need for a greater number of different branched fittings with fixed angles between the main pipe and the branch pipe, as well as for different pipe bends, further preserving the possibilities of maintaining a pleasing appearance through an appropriate external design.
  • this object is a- chieved by constructing the branched fitting with a main pipe component and at least one branch pipe component in the manner set forth in the characterizing clause of claim 1, in this manner providing a variably adjustable branched pipe-joint fitting, with which it is possible before, during and after the installation work to change continuously the angle ⁇ between the main pipe and a branch pipe, the branch pipe concerned being secured to the main pipe sealingly and rotatably about a rotational axis determined on the background of the angles ⁇ and e between each branch and the end-part plane of the as ⁇ sociated branch pipe, respectively, relative to their respective central axes.
  • the branched pipe-joint fitting according to the present invention may be twisted, turned and/or "wriggled” into position, this again contributing to achieving the desired adaptability during the installation work.
  • a branched fitting according to the invention is achieved that in a simple manner - partly depending on the requirement for the installation - may be adjusted continuously in angles between 0° and 180°, and preferably in the interval be- tween 45° and 90°.
  • the adjustment may e.g. be carried out by holding the main pipe stationary and turning the branch pipe, and may be carried out to both sides relative to the main pipe by turning the branch pipe all the way round, i.e. in a 360° rotation. Otherwise, the main pipe may be turned upside down, which in connection with the preferred interval means that the assembling angles can lie between 45° and 135°, thus covering the most commonly used commercially available angle bends.
  • the angle can, depending on the installation situation. be set and/or finely adjusted in position by simultaneous translation and/or rotation of the main pipe in and/or about its longitudinal direction, as well as by rotation of the branch pipe.
  • a securing connection as set forth in claim 3, i.e. a rib-and-groove connection, it is ensured that the branch pipe is held sealingly and rotatably connected to the main pipe without risk that unintended leaks could arise at some later time, e.g. caused by stresses introduced during the installation work.
  • a flow passage for the flowing liquid is provided, in which there is no risk of the formation of pockets or bulges likely to retain solid particles en ⁇ trained in the flowing liquid, because the placing of the engagement connection outside of the flow cross-section but still inside of the outer periphery of the branched fitting prevents them from constituting a hindrance for effective cleaning.
  • Figure 1 is a diagrammatic exploded side view, partly in section, of the branched pipe-joint fitting with the branch pipe placed at an angle a of 90° between the main pipe and the branch pipe.
  • Figures 2a-2d diagrammatically show a series of illustra ⁇ tive side views of the branched pipe-joint fitting
  • Figures 3a-3d diagrammatically show a series of illustra ⁇ tive views of the branched pipe-joint fitting as shown in Figures 2a-2d, but as viewed from the front.
  • the exemplary embodiment of a branched pipe-joint fitting 1 according to the invention shown in the drawing com ⁇ prises two pipe components, but it could, as mentioned before, just as well comprise more than two pipe co - ponents.
  • one component is constituted by a main pipe 10
  • the other pipe component is constituted by a branch pipe 30 being rotatably connected to the main pipe 10 through a branch spigot 20 placed on the main pipe 10.
  • the main pipe 10 may as shown be provided with pipe ends 11, 12 with mutually parallel end planes, normally sub ⁇ stantially at right angles to the central axis 5 of the main pipe 10.
  • the connecting end 23 of the branch spigot 20 lies in a plane advantageously forming an angle of 22.5° with a plane at right angles to the central axis 5. It is, of course, possible to choose other angles than those mentioned above, depending on the intended use of the branched pipe-joint fitting, but as a point of departure, the angles having been chosen have proved to provide the greatest possible flexibility in connection with the mutual rotation of the pipes and possibilities of connections to the drain pipes.
  • the branch pipe 30 is provided with a pipe end 31, the end plane of which nor ⁇ mally extends substantially at right angles to the central axis 35 of the branch pipe 30, and another pipe end 33 for connection to the branch spigot 20, the end plane of which advantageously forms an angle of 22.5° relative to a plane at right angles to the central axis 35.
  • both pipe components have engagement parts for their angularly set connecting ends 23 and 33, as shown in Figure 1 constituted by rib-and-groove engagement means 22 and 32.
  • the pipe components are shown separated from each other for better illustration of their rib ⁇ and-groove engagement means 22 and 32.
  • the pipe components may be assembled e.g. by means of a shrink joint, i.e. by e.g. the branch pipe 30 constituting a female part that may advantageously be heated, and the branch spigot 20 on the main pipe 10 constituting a male part that may advantageously be cool- ed, all in order to facilitate the assembly work.
  • the components may be assembled or connected with a snap connection.
  • the ribs and grooves as a whole designated 22 and 32, respectively, are preferably all formed as real bodies of rotation, meaning that they constitute bodies of ro ⁇ tation rotated about the rotational axes 15 and 45 of the branch pipe 30 and the branch spigot 20, respective ⁇ ly, enabling the pipe components to be rotated continu- ously relative to each other and form angles ⁇ in the interval 0°-180°.
  • the ribs and grooves as a whole designated 22 and 32 lie within the outermost periphery of the branch pipe 30 and the branch spigot 20, respectively, but still outside of their flow cross-sectional area, incidentally being substantially the same for the main pipe 10, the branch spigot 20 and the branch pipe 30, so that the branched pipe-joint fit ⁇ ting provides a flow passage for the liquid flow without obstructions or impediments.
  • this arrangement can also in itself be fluid- tight over the full circumference of the engagement con ⁇ nection.
  • a sealing ring may, however, be placed in the engagement connection in order to achieve an even more reliable seal.
  • the pipe ends 11, 12 and 31 are made with traditional or conventional inter ⁇ connection means, these means on the end 11 on the main pipe 10 and on the free end 31 of the branch pipe 30 being constituted by female parts for coupling with male parts on other pipe components or drain pipes, and the interconnection means on the other end 12 of the main pipe 10 being constituted by a male part for coupling with the female part of another pipe component.
  • the inside diameter of the female part is somewhat greater than the inside diameter of the remainder of the pipe, preferably corresponding to the wall thickness of the pipe, while the outside diameter of the male part either corresponds to or is somewhat less than the inside diameter of the female part, thus providing the male part with a spigot fitting within the female part, all without causing a variation of the flow cross-sectional area in the joint.
  • These commonly used muffs comprise i.a. a sealing ring for providing a seal between the interconnected pipe components.
  • connection to the drain pipes may be established in a simple manner without using e.g. special tools for screwing pipe parts and the like together.
  • the branched pipe-joint fitting 1 is shown with the end connecting part of the branch spigot 20 lying in a plane forming an angle ⁇ of 22.5° with a plane at right angles with the central axis 20 of the branch spigot 20, and with the end connecting part 33 of the branch pipe 30 lying in a plane forming an angle e of 22.5° with a plane at right angles with the central axis 35 of the branch pipe 30.
  • the central axis 5 of the main pipe 10 and the central axis 35 of the branch pipe 20 may form an angle ⁇ with each other that is con- tinously variable from 45° to 90°.
  • the angle ⁇ may, how- ever, be varied in the interval between 0° and 180°, depending on the construction of each branch spigot 20 and the associated branch pipe 30 having been chosen.
  • the central axis 5 of the main pipe 10 will likewise move and describe a surface of a cone.
