Definitions

  • the present invention relates to an assembly in accordance with the preamble of claim 1 for mounting an angled faucet union.
  • the invention also concerns a method for mounting the angled faucet union.
  • water piping in buildings should be easily replaceable. Moreover, a possible leak should be readily and immediately identifiable from within the premises. Therefore, water piping which is mounted behind the inner wall panel according to current construction practices is placed into a protective tube, and the tube itself is terminated to a recess box of an angled faucet union.
  • the recess box guides any leakage water into the room space.
  • the recess box is typically fixed with screws to the inner structures of the wall.
  • the recess box also has fixed to it an angled faucet union with a massive metal body, typically of brass.
  • the purpose of the angled faucet union is to deflect piping which runs parallel to the walls to a perpendicular direction with respect to the walls.
  • the purpose of the entire conventional angled faucet union assembly is to perform as a support structure for fixing the water piping, which by itself is relatively weakly attached to the internal structures of the wall, to the inner wall structures thereby providing an easier mounting of faucets in the premises.
  • the present invention is characterized by a light weight of the recess box and advantageous mounting method of the box by means of lightweight pegs.
  • the mounting method according to the invention is based on fixing the angled union directly onto the rear wall, instead of bracing it onto the recess box of the angled union. More specifically, the assembly according to the invention is characterized by what is stated in the characterizing part of claim 1.
  • the invention provides outstanding benefits.
  • the implementation according to the invention permits the use of an extremely lightweight construction of the recess box of an angled union.
  • manufacturing costs per box are reduced to a fraction from current costs, in particular when manufacturing large-volume series.
  • the installation becomes easier, because the recess box of the angled union can be premounted to the inner wall panel in a very early stage of building construction, thus avoiding the mounting of the box with complicated tools; in optimum cases the lightweight fixing pegs can serve as final fixing means.
  • Figure 1 shows in a side view a recess box according to the invention for an angled union, said box being fixed onto a thin sheet-metal wall panel.
  • Figure 2 shows in a front view the recess box of an angled union illustrated in Fig. 1.
  • Figure 3 shows in a front view the recess box of an angled union.
  • Figure 4 shows section B-B of the recess box of an angled union illustrated in Fig. 3.
  • Figure 5 shows section A-A of the recess box of an angled union illustrated in Fig.
  • Figure 6 shows in an enlarged side view a mounting member for the recess box of an angled union illustrated in Figs. 3...5.
  • Figure 7 shows in a front view an angled union assembly according to the invention.
  • Figure 8 shows in a rear view the angled union assembly illustrated in Fig. 7.
  • Figure 9 shows in a side view the angled union assembly illustrated in Fig. 7.
  • Figure 10 shows in a side view an alternative embodiment of the angled union assembly illustrated in Fig. 7.
  • Figure 11 shows in a side view an alternative mounting method according to the invention.
  • the recess box 1 of an angled union is fixed to the outside of a thin sheet-metal wall panel 2 in a manner which is essentially splash-proof.
  • Current plumbing codes dictate that in the case of a possible leak it must be detectable from the room side of the wall 2.
  • the angled union 10 is fixed to the sheet-metal wall panel 2 with the help of a threaded tightening ring 12. Additionally, a cover washer 47 is placed between the tightening ring 12 and the wall. The tightening ring 12 is tightened by rotating it on threads 13 fabricated on the threaded section 28 of the angled union 10.
  • a metal strengthening plate 11 is employed, particularly in conjunc ⁇ tion with heavy shower room faucets, between the angled union 10 and the wall panel 2.
  • the strengthening plate 11 is also provided with an opening, however, with such a shape that when the strengthening plate 11 is properly mounted, the plate glides down guided by its flange 42, to finally rest against the upper side of the recess box of the angled union, whereby the upper edge of the opening in the strengthening plate 11 remains resting against the upper side of the angled union 10.
  • a circular installation opening is formed for the angled union 10.
  • the strengthening plate 11 is not fixed permanently to the wall structure 2: but rather, during the mounting of the angled union 10. it becomes clamped between the flange 17 of the angled union and the wall panel 2.
  • the mounting flange 17 is advantageously formed by fixing tabs, which are directed to above and below the angled union 10. Due to factors related to the mounting method, the fixing tabs are omitted from the sides of the angled union 10.
  • a vertical support face 45 is formed on both sides of the angled union 10, said face butting against the bracing ridges 37 of the recess box 1 of the angled union.
  • the bracing ridges 37 clamp the angled union 10 sideways in place.
  • a cover cone 14 is placed to the room side of the wall panel 2, whereby said cover cone encloses underneath it the installation opening 19, the tightening ring 12 and a part of the threaded section 28 of the angled union.
  • the lightweight recess box 1 of the angled union encloses the angled section 25 of the angled union 10 remaining outside the wall panel, as well as its coupling 15, to which a water pipe is connected with the help of a clamp 6.
  • the cavity of the recess box 1 surrounding the angled section 25 is herein called an inner cavity 20.
  • a drain hole 40 from which water entering the inner cavity 20 of the recess box 1 of the angled union due to a possible leak is routed to the room space of the building.
  • a protective tube 5 of the water pipe 4 is fixed to a coupling 3 on the recess box of the angled union, said coupling having clamping teeth for the protective tube 5.
  • the recess box 1 of the angled union comprises flange-like tabs 16 on both sides of the cavity 20.
  • the recess box 1 is fixed to installation holes 18 of the wall panel 2 by means of pegs 35 formed on the fixing tabs 16.
  • the pegs 35 of circular cross section are provided with crosswise running annular locking grooves that achieve locking of the pegs in the wall panel 2.
  • the maximum outer diameter of the pegs 35 is approx. 2 % larger than the diameter of the installation holes 18.
  • the contour of the locking grooves resembles an equilateral triangle. To improve locking, it is also possible to employ locking grooves which have the locking slopes parallel to the plane of the wall panel 2.
  • the installation slots 49 which are fabricated on the strengthening plate 11 to accept the pegs 35, are aligned vertically and have oblong shape to allow the sliding motion of the strengthening plate 11.
  • the installation opening 19 fabricated on the wall panel 2 for the angled union 10 is made sufficiently large to allow vertical adjustment of the angled union 10 during the installation stage.
  • the tightening ring 12 of the angled union 10 is unscrewed, the free upward motion of the strengthening plate 11 also becomes possible, whereby the angled union 10 can be lifted up and then withdrawn to the room side of the wall panel 2. Due to the bracing ridges 37, the width of the inner cavity 20 of the recess box 1 of the angled union is reduced at the place of the angled union 10 so as to be approximately equal to the width of the installation opening 19 in the wall 2.
  • the recess box 1 of the angled union is fabricated from plastic by injection moulding. Suitable material is, e.g., polypropene which provides sufficient elasticity and rigidity. Alternatively to peg mounting, the recess box 1 can be fixed by screws or glue at its fixing tabs 16 to the core-side surface of the wall panel 2.
  • Figs. 3...5 illustrate typical dimensioning alternatives for the recess box of an angled union in accordance with the present invention.
  • the radius r x of the circular flange 16 of the recess box is approx. 35 mm
  • the inner cavity 20 has a maximum width of approx. 40 mm
  • the radius r 2 of curvature of the lower and upper parts of the inner cavity 20 is approx. 20 mm.
  • the width of the inner cavity 20 at the bracing ridges 37 is approx. 27 mm.
  • the total number of the fixing pegs 35 is four; the pegs are located in pairs on both sides of the inner cavity 20.
  • the spacing of the pegs 35 is approx. 20 mm in the vertical direction and approx, 50 mm in the horizontal direction.
  • inner cavity has a depth of approx. 40 mm and a height of approx. 70 mm.
  • the coupling 3 has a diameter of approx. 20 mm and a height of approx. 25 mm.
  • the wall thickness of the recess box 1 is approx. 2 mm.
  • the fixing tab 16 extends maximally by approx. 15 mm outward from the rims of the inner cavity 20.
  • the fixing pegs 35 have a height of approx. 5 mm and a width of approx. 5.1 mm maximum.
  • the tip of the peg 35 has a shape of a concatenated cone, whose tip angle is approx. 60° .
  • the locking grooves 30 have a width of approx. 1 mm and a depth of approx. 0.5 mm. The number of the locking grooves 30 is two.
  • the width of the angled union 10 is approx. 26.6 mm.
  • the total length of the flange section 17 is approx. 37 mm.
  • the angled union 10 illustrated in the diagrams is provided with a coupling 15 designed for a 15 mm dia. plastic pipe of supply water.
  • the long threaded section 28 is particularly adapted to the mounting of shower mixer faucet and a valve for a washing machine.
  • FIG. 10 The embodiment of an angled union illustrated in Fig. 10 having a smaller-diameter (12 mm dia.) coupling 15 for supply water and a short threaded section 28' is particularly adapted for connections to a toilet seat and copper piping of kitchen faucets.
  • FIG. 11 An installation method similar to that employed in the diagram of Fig. 1 is illustrated in Fig. 11 for connecting the angled union 10 to the piping of a sink and toilet seat as well as to the copper pipes of kitchen faucets. With the smaller mechanical load, the strengthening plate illustrated in Fig. 1 is unnecessary.
  • the material of the angled union 10 is a dezincification-resitant brass alloy.
