Definitions

  • the present invention relates to grillesformed by a series of horizontal bars interconnected by substantially vertical links and which are used as metallic shuttersfor the closure of bays and are 5 supported by a shaft mounted transversely in the top portion of the bay.
  • the rolling up of l the grille upon the shaft is abandoned by arranging the grille and its support in such a manner that the grille can pass over the shaft to be folded behind the latter, in a small volume. It is no longer necessary to provide around the shaft a considerable space for lodging the rolled up grille, and furthermore, the strain upon the shaft is considerably reduced as the total weight of the lifted grille is no longer supported by the shaft.
  • the shaft is provided with toothed wheels spaced apart and in the mesh-like structure of the grille are arrangedportions capable of meshing with the teeth of the said pinions.
  • the invention provides for folding the grille upon horizontal and upright supporting means beyond the shaft.
  • Adrawback in known linked grilles is that they are insufficiently rigid when lowered in front of the bay, this constituting a considerable defect when they must protect a show-window for instance, in this case there is a risk of the window being broken when the grille oscillates under a thrust or a shock.
  • the lowered grille is steadied by stretching it 55' transversely by traction upon the lateral edges.
  • the invention has also for its object a bearing for chain wheels which is constructed so as to allow the chain to pass through the bearing, for instance to allow a chain of considerable width, similar to the linked grille, to pass over a shaft coaxial with the wheel.
  • the chain wheel is supported not by its axis, as in ordinary bearings, but at its periphery by means of an arched support, in which a space is reserved between the support and the bottom portion of the interspace of the teeth of the wheel which is sufiicient for the passage of the link pins of the chain through the bearing when the wheel rotates with respect to its support.
  • connection of the wheel with the support is secured by the ends of the teeth of the wheel, which are provided with lateral projections in engagement with arch-shaped guide-ways.
  • the lateral projections of the wheel or the guide-ways of the bearing are provided with rollers or like elements.
  • the bearing may be constructed so that the guide-ways of the support are outside or inside the wheel.
  • a considerable advantage of the bearing for chain wheels according to the invention resides in the fact that, due to the possibility of making the chain pass through the bearing, the latter may be used as an intermediary support for a shaft coaxial with the wheel.
  • Fig. 1 illustrates diagrammatically a closed grille in front view
  • Fig. 2 is a section, on connection of the grille
  • Fig. 3 illustrates also on a larger scale an intermediary bearing for the supporting shaft of the grille and two folding devices
  • Fig. 4 is a horizontal section of a stretching device for the grille by means of a movable slide
  • Fig. 5 is a similar view of a removable stretching device and Fig. 6 illustrates the removable stretching device in elevation but on smaller scale;
  • Figs. '7 and 8 illustrate in detail a bearing for chain wheel with outer support, respectively in side elevation and in section on line VIII-VIII Q of Fig. I;
  • Figs. 9 and 10 are similar views of a bearing with outer support, the section in Fig. 10 being made on line XX of Fig. 9;
  • Figs. 11 and 12 illustrate a modification or 5 larger scale, of one link the bearing with inner support, in side elevation and in section on line XII-XII of Fig. 11 respectively;
  • Fig. 13 is a view in section of a modification of the bearing with outer support.
  • the horizontally linked grille shown in Figs. 1 and 2 is formed with horizontal bars I connected by links 2, which, in this example, are alternately straight and curved. These links 2, provided with eyes at their ends, are pivoted upon studs 4 connecting end to end two portions of a tubular bar I, as illustrated in Fig. 2.
  • lines 5 are provided where the bars I are spaced over a convenient width to mesh in the manner of the pins of a roller chain with driving pinions.
  • the grille comprises lines of interruptions 6, in which every other one of the bars I is interrupted between'two adjacent links, for the purpose of folding the grille.
  • the grille is supported in the top of the bay by a, horizontal shaft I, mounted in bearings 8 and which is provided with toothed pinions 9 arranged apart in alinement with the meshing lines 5 of the grille.
  • the shaft 1 is itself supported in intermediary bearings I 0, so that it may not warp under the weight of the grille.
  • a driving chain II At one end of the shaft or at both ends are provided a driving chain II with compensating counterweight I 2.
  • the shaft 1 acts only as an element for supporting and lifting and not as a rolling up device for the grille, which, when the shaft is caused to rotate, meshes with the pinions like a chain, passes over the shaft and is folded up beyond as illustrated in Fig. 3.
  • the bearing Ill comprises a rotary portion I3 in the shape of a toothed wheel, engaged upon the shaft 1 and supported at its periphery by arch-shaped guideways I4, in which run the rollers I5 mounted at the ends of the teeth of the wheel.
  • a passage I6 left between the fixed portion and the rotary portion of the bearing allows the passage of the bars I of the grille lodged in the interspaces of the teeth of the wheel I3, through the bearing for passing over the shaft I.
  • the wheel I3 has the same diameter and the same number of teeth as the pinions 9.
  • the continuous bars I slide over the curved end of the arm I8, the outer edge of said end 20 being at a level with the bottom portion of the interspaces of. the teeth of the wheels I3.
  • the arm I8 makes an upward bend and presents a slope 2
  • the grille is folded up along the arm I 8, the links 2 being placed vertically and progressing with the supporting bars I, which slide over the horizontal portion of the arm after having passed beyond a projection 22, which is intended to prevent them from again going down the slope 2I when a less supple link would interfere with the folding.
  • the grille leaving the wheel I3 after having passed over the shaft 1 is folded in a vertical receptacle 23, where its links 2 lie flat in superposition.
  • the regularity of the folding is secured by a curved guide 24, which collects the continuous bars I of the grille at their exit from the passage I6 and directs them towards one side of the receptacle 23, whereas the interrupted wbars Ia, which are not retained by the guide, are automatically directed towards the other side of the receptacle.
  • the bars Ia be interrupted, if only guides 24 are provided for the end portions of the bars; in this case one bar upon two is provided with an extension I b (Fig. l).
  • Fig. 4 On either side of the bay, the edges of the grille are guided in fixed or movable elements.
  • a fixed U-shaped guide 25 containing a movable bar 25a which may be pulled sidewards by means of a nut 26 screwing upon a threaded bolt 21 fixed to the movable bar 25a and passing through a hole of the fixed guide channel.
  • remov-' able stretchers may be used, such as those illustrated in Figs. 5 and 6 and which comprise a comb 28, the teeth 29 of which are engaged over the projections 30 of the bars I of the grille when the stretcher is applied to the fixed guide 25.
  • a screw 3I screwing in the rear end of a flange 21 from the comb and abutting the outer side of the guide 25 allows the pulling sidewards of the comb and the grille hooked thereto.
  • Pins 32 fixed to the guide 25 and which engage the transverse button hole slots 33 of the stretcher secure the support of the latter upon the guide.
  • a handle 34 allows the stretcher to be put in place and removed easily.
  • Fig. 6 is of a different type than that illustrated in Figs. 1 and 2.
  • rollers 43 for instance four in number for each tooth and mounted by pairs upon spindles 44, rollers which actually constitute the lateral projections by which the wheel 42 is supported at its periphery.
  • the rollers 43 run on both sides of the wheel 42 in curved guide ways 45, formed by two grooves provided coaxially to the: axis ofthe: wheehzlnside as'upport or seat 46 which.embracestheawheelzover about one half of its circumference.
  • the wheel 42 is thus-suspended in the bearing, 46, by the engagement of the rollers in theagrooves;.ithe relative'dimensions of the different parts being such that the wheel is supportedand-guided so as to be capable of rotating about itsaxis.
  • An ordinary bearing would require oneor two flanges embracing the wheel for supporting its-shaft, the present construct-ion leaves entirely :the'sides of the wheel free, except at the ends of the teeth engaging in the support 46 atntheupper portion of the wheel.
  • is not engaged in the support 46, so-that there remains between the bottom of the interspace of the teeth of the wheel and thearched end of the support, a free space 41 constituting a passage through the bearing for the pins 46 of :the chain 49 which meshes with the wheel.
  • the sides of the latter being free, the chain may have-a width much larger thanthat of the wheel, without its passage around the wheel being interfered with.
  • a tubular shaft 50 which is suspended from the support 46 by means of the wheel, to which it is connected for instance by means of flanged collars 5
  • the shaft 50 may drive the wheel 42 and thus cause the movement of the chain- 49, or otherwise the chain may actuate the wheel which then drivestheshaft.
  • the chain passes over the shaft by passing through the bearing supporting the latter.
  • the chain wheel 42 is constituted by two discs 42a, pressed against a core 42b by bolts 53a, which at the same time connect to the wheel the flanges 5
  • the discs 42a of the wheel are provided at the inner side, at the end of the teeth 4
  • the running rollers may also be arranged within the bearing 46, as illustrated at 43b in Figs. 11 and 12, so as to constitute a run Way for the segmentary lateral projections 44a. provided at the ends of the teeth 4
  • the segmentary projections 44a are formed by the edges of the discs 42a folded inwardly, and the bearing 46 has a T-section.
  • the wheel may rest upon the latter, the concavity of the support being then turned upwards and the guide or run ways being arranged accordingly.
