Definitions

  • the present invention relates to apparatus for raising and lowering a load and is concerned in particular, but not exclusively, with apparatus for raising and lowering a refuse container arranged to be kept below ground level.
  • the raising and lowering apparatus provided in accordance with the invention also has application independently in uses other than for raising and lowering a refuse container, and in such aspects it is an object of the invention to provide apparatus for raising and lowering a general load, where only a small operating force is available to effect the raising or lowering, and where the load to be raised or lowered is variable.
  • apparatus for raising and lowering a refuse container arranged to be kept below ground level comprising a movable support for the refuse container, counterbalance means for applying an upward force to the container support to counterbalance the refuse container in operation, actuating means operable by normal effort of a single operator to impart a raising or lowering movement as required to the container support, and weight compensating means for varying the effective upward force applied to the container support by the counterbalance means to compensate for differing weights of refuse in the refuse container.
  • the counterbalance means may comprise any means for applying a counterbalancing force to the container support in operation, for example hydraulic or electrical, and in some arrangements the counterbalance means may comprise one or more springs which when compressed apply a counterbalancing upward force to the container support.
  • the counterbalance means comprise a counterbalance weight for applying the upward force to the container support, the arrangement being such that as the refuse container is raised to ground level, the counterbalance weight is lowered, and vice versa.
  • apparatus for raising and lowering a refuse container arranged to be kept low ground level comprising a movable support for the refuse container, a counterbalance weight for applying an upward force to the container support to counterbalance the refuse container in operation, means coupling the support to the counterbalance weight in such a manner that raising of one results in lowering of the other, actuating means operable by normal effort of a single operator to impart a raising or lowering movement as required to the container support, and weight compensating means for varying the effective upward force applied to the container support by the counterbalance weight to compensate for differing weights of refuse in the refuse container.
  • the counterbalance weight and the container support are coupled to each other by a system of lines and pulleys, the container support and the counterweight both hanging freely by lines whereby they are raised and lowered.
  • the line is formed by a cable, but the line may be constituted by any suitable form of elongate flexible coupling means such as rope, cable, tape, strap, or even chain.
  • the said movable support for the refuse container conveniently comprises a flat horizontal load platform on which the refuse container stands, but in other rangements the movable support may comprise a hook or other form of coupling for coupling a line to the load, or may even be constituted by the end of a rope or the like adapted to be tied to a load.
  • the said actuating means may comprise any suitable form of lever wheel or like device to be operated by a human operator, by hand or foot, but preferably the actuating means comprises a pair of foot-pedals arranged in such a manner that as one foot-pedal is depressed the other rises, and vice versa, the arrangement being such that operation of one foot-pedal causes raising of the refuse container, and operation of the other pedal causes lowering of the refuse container.
  • the said weight compensating means may be under the direct control of the operator, so that for example the operator selects a reduced upward force on the container support when the container is less full, and selects an increased upward force applied to the container support when the container is more full.
  • the weight compensating means may be automatic, and there may be provided means for sensing an imbalance between the weight of the load on the container support, and the effective upward force provided by the counterbalance means, and means for varying the effective upward force in response to this imbalance, in such a manner as to correct the imbalance.
  • the said weight compensating means may comprise any form of adjustment, for example means for increasing or decreasing the spring pressure available in a sprung form of counterbalance means, for example by varying the compressed length of a spring, or means for varying the area over which a hydraulic pressure is applied to counterbalance the weight of the load.
  • the weight compensating means may be a simple mechanical device for varying the effective upward force applied to the container without the application of any force to the apparatus other than the operating force of the operator.
  • the said weight compensating means comprises a conical or frustoconical rotor rotation of which raises and lowers the said container support, and a line coupled to the container support or to the counterbalance means and wound about the conical or frusto-conical rotor, the said weight compensating means comprising means for varying the position along the axis of the rotor at which the line is wound.
  • the said position varying means comprises a movable position element (such as a pulley on a rod positioned parallel to a hypotenuse of the conical rotor) which is movable to different positions along the general direction of the axis of the rotor and acts to guide the line onto the conical surface of the rotor at the axial position of the position element, the position element being urged, at least at one stage of operation, in one direction along the general direction of the rotor axis by a biasing force the magnitude of which is dependent upon the axial position of the element, and in the opposite direction along the general direction of the rotor axis by a force which is dependent upon the weight of the load on the said container support.
  • a movable position element such as a pulley on a rod positioned parallel to a hypotenuse of the conical rotor
  • the conical or frusto-conical rotor is mounted on a main frame of the apparatus, and the position varying means comprises a control means for moving the conical or frusto-conical rotor in a direction along its axis relative to the main frame, the axial position of the line being constant relative to the main frame and the conical rotor being moved relative to the line position to achieve the required variation of winding position.
  • biasing means for urging, at least at one stage of operation, the conical or frusto-conical rotor in one direction along the general direction of the rotor axis by a biasing force the magnitude of which is dependent upon the axial position of the rotor, and a control means for urging, at least at one stage of operation, the rotor in the opposite direction along the general direction of the rotor axis by a force which is dependent upon the weight of the load on the said container support.
  • the conical or frusto-conical rotor has an axial channel therein in which when the channel is facing vertically downwards the line lies in a vertical plane including the axis of the rotor, to allow the required axial movement between the line and the conical or frusto-conical rotor, there being provided a further line connected to the other of the said container support or counterbalance means, the said further line being wound about a further, constant diameter, rotor which is coupled for rotation with the conical or frusto-conical rotor, the said constant diameter rotor including a slot corresponding to the channel in the conical or frusto-conical rotor, the said second line being adapted to lie in its said slot when the first line lies in its said channel.
  • the said conical or frusto-conical rotor may have a substantially even conical surface about which the line is wound, but it is to be appreciated that in some arrangements the rotor may have a stepped, grooved, or otherwise shaped surface (for example, defining paths for the line to be wound along), so long as the overall effect is that the diameter of the rotor varies along the direction of the axis of the rotor so that the effective force applied to rotate the rotor by the line wound around it varies with the axial position at which the line is wound around the rotor.
  • weight compensating means which has been set out above also has application in other fields where it is required to raise and lower a variable load.
  • apparatus for raising and lowering a load comprising a movable support for the load, counterbalance means for applying an upward force to the load support to counterbalance the load in operation, actuating means operable by normal effort of a single operator to impart a raising or lowering movement as required to the load support, and weight compensating means for varying the effective upward force applied to the load support by the counterbalance means to compensate for differing loads, the weight compensating means comprising a conical or frusto-conical rotor rotation of which raises and lowers the load support, and a line coupled to the load support or to the counterbalance means and wound about the conical or frusto-conical rotor, and means for varying the position along the axis of the rotor at which the line is wound.

  • FIG. 1(a), (b), and (c) there is shown partly diagrammatically a raising and lowering apparatus embodying the invention indicated generally at 21, for raising and lower a load platform 9 by means of a cable 17 passing over a pulley 22 secured to a fixed point 23.
  • the cable 17 leads to a further pulley 24 of the main apparatus.
  • a counterbalance weight 8 is suspended from a second cable 18 which also passes into the main body of the apparatus.
  • the counterweight 8 is such as to approximately balance the weight of the platform 9 when carrying its load, and the arrangement is such that as the load platform 9 rises the counterweight 8 falls, and vice versa.
  • the apparatus has a main frame 1 in which is mounted a main shaft 2 which carries a conical drum 16 and a fixed diameter drum 20 which are fixed relative to each other but rotate relative to the frame 1.
  • the cable 17 from the load platform 9 is led around the pulley 24 to a further pulley 25 rotatably mounted on a balance rod 3 (to be described more fully hereinafter) and thence to a pulley 26 which guides the cable 17 onto the fixed diameter drum 20.
  • the cable 18 supporting the counterweight 8 is wound a small number of turns, for example once, around a feed pulley 13 which is mounted on the balance rod 3 in such a manner as to allow rotation about the rod 3, but to be fixed against movement along the rod 3.
  • the counterbalance cable 18 then passes to the conical drum 16, where it is fixedly attached to a position element constituted by a bush 14 which is slidable along a runner 15 positioned approximately along the surface of the cone 16, along a hypotenuse of a section through the cone 16 containing the central axis of the cone.
  • the balance rod 3 is mounted in apertures in the frame 1 such that it can slide along its length from left to right in Figure 1(a), and the rod 3 is biassed to the left in Figure 1(a) by tension spring 27 acting between an edge 28 of the frame 1, and a screw threaded end piece 19 which may be screwed into or out of the main rod 3 to provide an adjustment of the tension in the spring 27.
  • Movement of the rod 3 along its length to the left and right is normally prevented by a brake 7 consisting of a pair of rigid flat bars 29 and 30 which have elongate holes 31 and 32 through which the rod 3 passes.
  • the bars 29 and 30 are inclined to each other and are urged together by a tension spring 33 at their upper end.
  • the feet are maintained apart by grooves or ridges (not shown) in the frame 1.
  • a cam 34 which may be raised or lowered by a brake lever 10.
  • the cam 34 is not between the upper ends of the bars 29 and 30, the upper ends of the bars are urged together by the spring 33, and the oval holes 31 and 32 jam the rod 3 preventing longitudinal motion thereof.
  • the cam 34 is forced between the upper ends of the bars 29 and 30, the bars are forced apart and the rod 3 is free to move along its length.
  • the brake lever 10 is capable of pivoting movement about a pivot 35, and in such movement operates two brakes 7 and 6.
  • the brake 7 has been described, and the brake 6 consists of a sprung metal strip positioned around an extension of the fixed diameter drum 20, and supported by a bracket 36. In its relaxed position, the brake 6 clamps onto the fixed diameter drum 20 and holds the drum against rotation.
  • the upper ends of the sprung strip 6 are bent outwardly in two flanges 37 and 38 ( Figure 2(b) and Figure 3) and between these flanges is a wedge cam 39, fixedly secured to the brake lever 10.
  • the brake lever 10 is biassed upwardly by a tension spring 40, so that in its rest position, the cam 39 is held clear of the flanges 37 and 38, and the brake 6 is clamped to the drum 20.
  • the brake lever 10 is forced downwardly, the brake 6 opens and frees the drum 20.
  • Operation of the apparatus is by two foot-pedals 4 and 5 arranged so that when one pedal is raised the other is lowered, and vice versa.
  • lines which in the present example are formed by narrow straps 11 and 12.
  • Each strap 11 and 12 passes along a path leading initially up and over a freely rotating pulley 41 on the brake lever 10, and then downwardly to wrap around a narrow diameter drum 42 which is fixedly mounted relative to the drums 20 and 16, and rotates on the main shaft 2.
  • the paths of the straps 11 and 12 are shown in Figure 1(c) to be off-set along the axis of the shaft 2, and the windings are arranged so that when the foot-pedal 4 is in the raised position, its strap 11 is fully wound on the narrow diameter drum 42, and at the same time the foot-pedal 5 is lowered and its strap 12 is fully unwound from the narrow diameter drum 42, and vice versa. Depression of the foot-pedal 4 causes the strap 11 to unwind from the drum 42 and to produce rotation of the drum 42, in a manner to be described more fully hereinafter.
  • the raising and lowering apparatus may conveniently be installed and mounted beneath a canopy 44 set into the ground, with the load platform 9 movable down into a shaft set in the ground (not shown). Similarly the counterbalance weight 8 is sunk into the same, or a different, shaft and can rise and fall on the cable 18.
  • the cable 17 for the load platform (which is shown diagrammatically in Figure 1(a) as a single cable) is in practice conveniently provided by three cables 17' shown in plan view in Figure 4(a), and led around a number of pulleys 22', which in Figure 1(a) are shown diagrammatically as a single pulley 22.
  • the load platform 9 is supported by three cables 17' for stability.
  • the canopy 44 has a cover 45 which opens in two hemispherical halves. Operation of the foot-pedals 4 and 5 is arranged to automatically open the cover 45 as appropriate, by means not shown, but which will be apparent to one skilled in the art.
  • a conical drum 16' is mounted on a main hexagonal cross section shaft 2' so as to be slidable along the shaft 2', but to be secured against rotation relative to the shaft 2'.
  • a cable 18' enters through a main frame 1' of the apparatus 21' (figure 6) the cable 18' being secured to a counterbalance weight in the same manner as in the embodiment of figure 1 (a).
  • the chief difference between the two embodiments shown is that in the embodiment of figure 1 (a) the conical drum 16 is fixed, and the position of the cable 18 is varied along the axis of the conical drum 16.
  • the position of the cable 18' is fixed relative to the frame 1', and the conical drum 16' is moved axially along the shaft 2'.
  • the conical drum 16' is supported on the shaft 2' by an end plate 115 and by an end piece 101, both of which have hexagonal apertures which are a sliding fit on the shaft 2'.
  • the shaft 2' is rotatable in bearings 114 and 117 in the main frame 1'.
  • a drill hole 120 in the drum 16' allows the cable 18' to be secured therein with a nipple (not shown) on the end of the cable 18'.
  • the drum 16' is stepped at 121 throughout its length, each step being sufficient to allow three wraps of the cable 18'.
  • the drum 16' has a channel 116 cut to the centre of the drum so as to allow the drum 16' to be moved axially along the shaft 2' when the channel 116 is at the vertical bottom position. During such movement, the cable 18' passes sideways along the channel 116.
  • the axial movement of the drum 16' is controlled by a U-shaped control lever 100 which is pivotable about a pivot rod 106 mounted on lugs 105 which are stamped out of the top of the frame 1'.
  • the extremes of movement of the lever 100 are shown in dotted lines at 122 and 123 in figure 6.
  • the lever 100 is urged to the left in figure 6 by a bias spring 27', and the movement to the right of the drum 16' is effected by the effect of a pulley 25' mounted at the upper part of the lever 100, and operated by the effect of three cables 17' secured to the load platform of the apparatus, as will be described hereinafter.
  • the lower end of the lever 100 carries a steel support 102 (figure 7) which pivots in pivots 103, and is clamped around the end piece 101 of the drum 16' in such a manner as to provide a bearing allowing rotation of the drum 16' in the steel support 102.
  • the fixed diameter drum 20' is fixedly secured to the hexagonal cross section part of the shaft 2' by an end plate 120, the remainder of the shaft 2' at the right hand end in figure 6 having a circular cross section, to be mounted eventually in the bearing 117.
  • the drum 20' has a particular feature absent from the drum 20 in figures 1 to 5 of the specification, namely that a slot 104 is cut in the drum 20' at a particularly chosen angle relative to the channel 116 in the drum 16'.
  • the slot 104 is shown particularly in figures 10 and 11, and occurs at the right hand end of the drum 20'. In the particular example shown, the slot 104 is at an angle of 19° to the channel 116 in the drum 16'.
  • the purpose of the slot 104 is to allow the load platform cables 17' to pass into the slot 104 at a particular timed phase of the rotation of the conical drum 16'. It will be appreciated that when the counterbalance cable 18' is aligned directly from the centre of the shaft 2' vertically through the channel 116 (when that channel is vertical) the counterbalance cable 18' exerts no rotational force on the drum 16' about its axis. Only when the cable 18' is in its normal position (part wound around one of the steps 121) does it exert a moment giving a rotational force about the axis of the shaft 2'.
  • the path of the load cable 17' around the drum 20' has to be planned to take account of this period when the counterbalance cable 18' is aligned along the channel 18' of the drum 16'. This is achieved by the slot 104 in the drum 20'.
  • the load platform cables 17' are lying completely in the slot 104, there is again virtually no rotational force exerted on the drum 20' by the cables 17', and this is arranged to occur at the same time that the cable 18' lies in the channel 116 of the drum 16'.
  • a corresponding increase takes place at the same time of the rotational effect of the cables 17' on the drum 20', as a corresponding increase in horizontal displacement of the cable 17' from the axis of the shaft 2' takes place.
  • the increasing horizontal displacement of the cable from the axis of the shaft is produced by the turning of the channel 116 and of the slot 104.
  • the increasing effect of the counterbalance weight matches the increasing effect of the load platform.
  • a drill hole 112 for the three cables 17' there are shown a drill hole 112 for the three cables 17', and a hole 113 to receive a screw (not shown) for securing the cables 17'.
  • a hole 118 is provided to secure cables 11' and 12' operated by pedals 4' and 5'.
  • Foot pedals 4' and 5' are linked by cables 11' and 12' to a small diameter drum 42' to achieve required rotation of the shaft 2' by the operator for raising and lowering the load.
  • the pedal cables 11' and 12' pass to the drum 42' via a pulley 41' mounted on a brake lever 10' which is pivotted at 35' and biased upwardly by spring 40'.
  • the brake lever 10' has a wedge cam 39' (circular in section) which opens and closes a brake 6' operating on part of the drum 20'. All these components operate in the same manner as in the previous embodiment.
  • the first step will be the release of the brake 6'.
  • the channel 116 of the drum 16' will be vertical and as soon as the brake 6' is released, the increased tension in the cables 17' passing around the pulley 25', will pull the lever 100 to the right in figure 6. This will move the drum 16 to the right so that the counterbalance cable 18' will be presented with a wider diameter step 121 to be wound around.
  • the lever 100 stops moving to the right when the increased tension in the cables 17' balances thebias spring 27'.
  • the present invention provides a number of advantages over previously known arrangements.
  • a mechanism for use where a varying load is to be raised and lowered on a platform attached by a cable and pulley to a counterweight, and where the manual effort required to operate the apparatus remains minimal and constant notwithstanding different loadings on the platform.
  • a refuse arrangement which has the neat appearance of a below ground container for rubbish, and which is convenient and easy to fill and empty. Advantages include minimal foot pressure and relatively short length of travel needed for the operating pedals. The operator does not need to lean over or bend down.
  • the cover can be arranged to be raised and lowered automatically. Access to the load platform is available only when the shaft is occupied by the platform and the container, to reduce danger of falling into the shaft.
  • the design allows for cleaning of the inner container if rubbish is inadvertently spilled over the sides of the dustbin, and a simple lock can be provided to make the container child and vandal proof.

Abstract

Un appareil permettant de monter et descendre un conteneur à ordures que l'on garde à un niveau inférieur au rez-de-chaussée comprend une plateforme de chargement (9) suspendue à un câble (17), un contre-poids (8) suspendu par un câble (18), un tambour conique (16) autour duquel le câble (18) du contre-poids est enroulé, et un tambour (20) de diamètre fixe autour duquel le câble (17) de la charge est enroulé. En cours d'utilisation normale, le poids de la charge sur la plate-forme de chargement (9) varie en fonction du degré de remplissage du conteneur à ordures. Pour prendre ceci en considération, le câble (18) du contre-poids est enroulé autour du tambour conique (16) en différentes positions sur sa longueur axiale. Ceci s'effectue en montant une poulie d'alimentation (13) sur une tige d'équilibrage (3) laquelle est déplacée automatiquement sur sa longueur par l'effet de l'augmentation ou de la diminution de la tension du câble de charge (17) en conséquence de l'augmentation ou de la diminution de la charge. Dans un appareil modifié (non illustré), la position axiale du câble (18) est maintenue constante et le tambour conique est déplacé le long de son axe par rapport au câble (18).
