Definitions

  • the present invention relates to a device for securing a side plate on a radiator, at least one connection pipe to the radiator extending through an aperture in the side plate and being connected to a connection member on the radiator inside the side plate, and the connection member having a radially projecting bead or one or more projections.
  • Radiators for waterborne heat are often designed as duplex radiators and have a front and a rear radiator between which convector plates are disposed so that the heat-emitting surface of the radiators is considerably improved. Alternatives with single radiators and triple radiators also occur.
  • the space above the radiator or radiators is closed by means of a grid so that air flowing in from beneath in the heated state may depart upwardly.
  • the radiator has cover plates, principally for aesthetic reasons, but also in order to realise a chimney effect through the radiator.
  • the radiator has connections for the supply and removal of water. As a rule, these inlets and outlets are placed over one another one on each end side. Connection to them is put into effect by means of pipes horizontally connecting to the radiator which, as a result, must be passed through at least one side plate, but possibly through both.
  • the C-C distance between the connections according to valid standards may vary as much as ⁇ 2 mm.
  • the distance between the centre of the upper most connection and the upper side of the radiator may vary by ⁇ 1 mm.
  • the side plates have, on the insides, upper and lower pairs of ⁇ shaped snap catches which grasp about the transverse connection pipes which extend between the front and rear radiator plate, i.e. the component radiators of which the radiator is constructed. Since these plastic clips localise the side plate in dependence upon the position of the transverse connecting pipes, and these in turn constitute an integral part of the connection member which, on the one hand, interconnects the component radiators with each other and, on the other hand, connects the external conduits, the side plates must have such large passage apertures for the external conduits that this solution will be aesthetically unacceptable. In addition, there will be poor precision in the connection of the side plates to the grid running along the upper side of the radiator.
  • the side plates have, at their upper end, downwardly directed projections which are passed through corresponding apertures in the grid on the upper side of the radiator.
  • the side plate has catches produced from flexible steel wire which are caused to grasp in under the transverse pipe placed under the connection and extending between the front and rear component radiators.
  • the side plate is positioned in a vertical direction by the positioning of the upper grid.
  • rotary washers which are placed in the side plates and which have somewhat oval apertures for the external connection conduits and which, along approximately a semicircular arc, have gripping members which are intended to grasp behind a bead on the connection of the radiator.
  • Such a side plate is slid on the connections from above, whereafter the plastic washers are rotated a quarter of a turn or more.
  • a side plate of this type can not be lifted off the radiator because of the rotation of the plastic washers but positions the side plate in dependence on the position of the connections of the radiator. This implies that the side plate, above all in the vertical direction, may be positioned so high that a gap occurs towards the upper grid of the radiator.
  • the present invention has for its object to design the device intimated by way of introduction such that, regardless of the tolerances of the positions of the connections of the radiator, it is always capable of positioning the side plates in correct positions in relation to the radiator proper, in particular its upper grid.
  • the present invention further has for its object to realise a device which is simple to mount and dismount and which does not run the risk of being released from the radiator if the radiator were to be lifted by gripping the side plates.
  • the present invention has for its object to realise a device which is aesthetically appealing and which may be manufactured at low cost.
  • the device intimated by way of introduction is characterised in that a snap device is disposed on the inside of the side plate and at the aperture therein, the snap device being movably connected to the side plate for limited movements approximately parallel with the plane of the side plate, the snap device having an aperture through which the connection pipe extends, and the snap device having at least one snap member which is catchable inside the bead/projection/projections.
  • the snap device may adjust itself in response to the tolerances which the connection member or connection members may have.
  • the present invention is further characterised in that the snap device or its snap member is spring pretensioned in order to exercise a downwardly directed force against the side plate.
  • the major advantage will be afforded that the side plates are always kept in close abutment against the grid on the upper side of the radiator.
  • Figs. 1-4 show a separate side plate according to the present invention.
  • the side plate 1 is rectangular in configuration and has an upper edge portion 2 which is intended to rest on the upper side of a grid which covers the upper side of the radiator and which may substantially make a right angle with the side surface 3 of the side plate.
  • the side plate 1 has a front edge portion 4 and a rear edge portion 5 which are formed to straddle the front and rear side of the radiator and possibly abut against them.
  • the edge portions may be approximately parallel with each other and transversely directed, possibly at right angles to the plane of extent of the side plate.
  • the term front relates to the side of the radiator facing towards the observer, while the rear relates to the opposite side, preferably the side facing towards a wall.
  • the side plate 1 has apertures 6 and 7 for passage of external connection pipes and the apertures have collars 8 and 9, respectively, which extend inwards in a direction in towards the radiator.
  • the two apertures 6 and 7 are of such over dimensioning in relation to the external connection conduits of the radiator that the tolerances disclosed by way of introduction for the C-C dimension of the connections and also the dimension from the upper connection conduit to the upper side of the grid of the radiator can reliably be encompassed.
  • Fig. 5 shows, in the cut-away state, an upper corner region of a radiator.
  • reference numeral 10 relates to a rear or inner component radiator
  • reference numeral 11 relates to a transverse connecting pipe which connects the rear component radiator 10 with a front component radiator (not shown).
  • the connection pipe 11 has a connection member 12 to which an external connection pipe is intended to be connected.
  • the connection member is, in the illustrated embodiment, tubular and has, at its outer, free end, a number of radially projecting projections or a circumferential, annular bead 13.
  • a snap device 14 is fixed on the inside of the planar side surface 3 of the side plate in such a manner that it is positionally fixed to and from the side plate but so that it is restrictedly movable approximately parallel with the plane of the side plate.
  • the snap device has at least one snap member 15 which, on mounting of the side plate 1, is intended to snap in behind the bead 13 and partly surround the tubular connection member 3.
  • the snap device 14 has, around the snap member or snap members, one or more entry surfaces 16 which, when they are pressed against the axial outer edge of the bead 13, are intended to displace the snap device so that a snapping-in of the snap members 15 behind the bead is facilitated.
  • the entry surfaces form a space which is radially inwardly converging in a direction towards the planar side surface 3 and which, in a circumferential direction of the connection member 12, accommodates approximately a half turn.
  • the snap device 14 further includes a spring member 17 which abuts against an abutment portion 18 on the inside of the planar side surface 3 of the side plate and is preferably formed as a part of the collar 8 or 9 or an extension thereof inwards towards the radiator.
  • the spring member is designed so as to urge the snap members from beneath against the under side of the connection member 3, whereby, as a reaction hereto, a downward force may be imparted to the whole of the side plate 1 so that the upper edge portion 2 of the side plate always abuts against the upper surface of the radiator.
  • the snap device 14 is, with its snap members, entry surfaces and spring member, of one piece manufacture from a suitable plastic material.
  • Fig. 6 shows the snap device 6 seen from the inside, i.e. from the radiator and outwards towards the inside of the side plate 1.
  • the entry surfaces 16 and the spring member 17 are clearly apparent.
  • the snap device has a circumferential wall 20 which defines an aperture 19 through which the connection member 12 and the external connection pipe may be passed.
  • the snap device has, in its lower end, a recess 21 which is laterally defined by two projecting heels 22.
  • the collars 8 and 9 have, in their lower region, a T-shaped projection 23 with a head 24 and a neck 25.
  • the neck 25 is intended to be located in the recess 21 in the snap device 14 but is of lesser width than the recess 21, for which reason a certain freedom of movement occurs in the width direction of the recess 21 and also in its vertical direction.
  • the head 24 is intended to be located over or inside the two heels 22 so that the snap device 14 is thereby prevented from moving transversely of the plane of extent of the side plate 1.
  • the collars 8 and 9 have, in their upper region, on the one hand the above-mentioned abutment details 18 and, on the other hand, upwardly bent projections 26 which are intended to rest against the edge of the spring member 17 facing towards the radiator in a recess 27 therein.
  • the projection 26 abuts against the side of the spring member 17 facing away from the side plate1
  • the snap device is prevented from moving transversely of the plane of extent of the side plate.
  • the recess 27 is of greater width than the projection 26, the snap device can, on the other hand, move parallel with the plane of extent of the side plate.
  • Figs. 10 and 11 show the side plate with mounted snap devices 14, and, in Fig. 10, the bead 13 is further intimated on the connection portion.
