Definitions

  • the subject invention concerns a wheel which is intended primarily for food trolleys, grill carts and the like and the outer portion of which comprises an outer annular member having at least one outer race which is open towards the centre and into which rolling elements are filled when the wheel is mounted in position, said elements also cooperating with corresponding inner races which are open outwards and which are formed in the periphery of an inner annnular member.
  • the wheels may be mounted to the trolley in various ways.
  • a common solution is to use a fixed shaft which is positioned below the trolley bottom face and to mount the wheels on the shaft.
  • two shafts are used.
  • the wheels may be removably attached.
  • One example of application of this construction is for pram wheels.
  • Another solution is to mount each wheel on i ⁇ s individual stub axel which in turn is secured in a fitting element mounted on the trolley.
  • this solution provides the designer with more freedom in positioning the wheels on the trolley since it is no longer necessary to use a transverse shaft extending below the bottom face of the trolley, a considerable number of different mounting members are required to suit different types of trolleys.
  • the disadvantage is that the wheels cover a large area of the lateral faces of the trolley. This disadvantage becomes particularly obvious when the wheels are large and the trolley is equipped with a large number of compartments to which one wishes to have easy access from various directions.
  • the purpose of the subject invention is to remedy the drawbacks outlined in the aforegoing by providing a novel wheel construction which is easy to manufacture and may be mounted in a stable manner to the trolley while at the same time the lateral faces of the trolley are easily accessible.
  • the wheel construction in accordance with the invention thus is essentially characterized in that the wheel has no hub in the ordinary sense of this term. Instead, it has an open centre through which the trolley is accessible. This is achieved as a result of the particular construction of the wheel wherein the outer annular member of the wheel cooperates with an inner annular member with the aid of rolling elements.
  • the inner annular member is not closed but consists of a segment, i.e. an open ring, and it is provided with a profiled engagement member.
  • a lateral moulding may be slid over the engagement member and the lateral moulding is designed to secure the wheel to the trolley.
  • the inner annular member and the lateral moulding both may be manufactured from helically wound extruded bars or sections of appropriate cross-sectional con ⁇ figuration, for instance of aluminium.
  • bars or sections of identical cross-sectional configuration may be used for a large range of wheel dimensions and only the outer annular member is individual to each size.
  • the lateral moulding and the inner annular member as a rule have an identical inner diameter, making it possible to use a mandrel common to both. Particularly in the case of small-series manufacture, the manufacturing costs will decrease accordingly.
  • a conventional wheel of this kind covers a large area of the lateral faces of the trolley while at the same time it exposes the associated shaft stub axle to considerable load.
  • a further advantage is that the wheel in accordancae with the invention may be attached in various points along its periphery and not merely, as is the case with conventional wheels, at its hub or centre. This gives the designer considerable freedom in the design of the trolley. Furthermore, it is no longer necessary to provide different stub axles for each type of trolley, which as a rule is the case when conventional wheels are used. 2017 l - im . i o ⁇ -
  • the wheel may double as a handle to lift or roll the trolley. There are no spokes or hubs that prevent or interfer with the grip as is the case with conventional wheels. Another very important advantage is that stationary parts and not rotating ones are gripped for this purpose, viz. the inner annular member and the lateral moulding. Examples of applications where this is a particularly vital feature is in wheel-chairs and unloading trolleys for station wagons and small freight trucks.
  • the wheel may also be formed with a profiled engage ⁇ ment rib also on its outer face, i.e. the face remote from the vertical side of the trolley.
  • This outer engagement rib may either be formed integrally with the section from the start, for instance by configuring the die casting tool accordingly, or else, the outer engagement rib may be screwed in position later.
  • An outer lateral moulding may then be slid over the outer engagement rib.
  • Accessories in the form of e.g. stands, holders, fittings and/or handles may then be mounted on this outer lateral moulding as the need arises.
  • the lateral moulding may also be formed with recesses for reception therein of an engagement rib on its two axial faces, allowing it be be surrounded by an inner annular member on either side and thus by a wheel on either side. Owing to this arrangement it becomes possible to mount several wheels side by side, i.e. positioned axially next to one another. These wheels may have different outer diameters because of the differences in thickness of the outer annular members. Likewise, it is possible to provide the inner annular members with screw holes, whereby two inner annular members may be screwed together in direct juxtaposed relationship. In this manner, also the outer annular members will be juxtaposed close together.
  • the wheel may be of different external diameter size, the larger wheel being used for instance for displacement of the trolley on the floor while the smaller wheel may cooperate with rails or tracks joined to the floor, allowing the trolley to be rolled in a simple manner along a ramp on rails above the floor level.
  • the wheel has been conceived primarily for use together with mobile interior fittings and similar equipment, mainly for indoor applications and essentially for application in appliances having low-rotational speed and exposed to moderate load.
  • the wheel construction lends itself to the realiza ⁇ tion of extremely stable wheels and extremely stable wheel mountings. This is particularly important in the case of mobile interior-fitting units in the form of mobile chopping blocks or work benches that have to respond favourably to working operations involving impacts or the like.
  • any amateur handyman possessing average skills may easily loosen the locking screws of the lateral moulding and, by pushing the moulding aside, make the rolling elements accessible for replacement.
  • the lateral mouldings are easily replaced or supplemented afterwards in a comparatively simple manner.
  • Fig. 1 is a perspective view of a grill trolley.
  • Fig. 2 is a vertical sectional view through one of the wheels of the trolley and the parts associated with the trolley,
  • Fig. 3 is a perspective view of the outer annular member of the wheel and a tubular blank used to manufacture the outer annular member, 3a, and likewise shows a cross-sectional view through the annular member, 3b.
  • Fig. 4 is a perspective view of a helically wound starting blank intended for the inner annular member, 4a. and a cross-section through said inner annular member 4b.
  • Fig. 5 is a perspective view of a helically wound starting blank intended for the lateral moulding, 5a, and a cross section through said moulding, 5b.
  • Fig. 6 illustrates a method of inserting the rolling elements between the outer and inner annular members, and other features of wheel mounting.
  • Fig. 7 illustrates another method of inserting the rolling elements between the outer and inner annular members, 7a, and a method of mounting the wheel, 7b.
  • Figs. 8a and 8b illustrate an assembled wheel, additionally provided with a bracket of particular design for mounting the wheel to the bottom of the trolley.
  • reference numeral 2 designates a grill trolley fitted on its top with an upright catalytic LP-gas operated grill.
  • the trolley is fitted with drawers and foldable flaps and could also be fitted with racks for storage of wine bottles.
  • Related types of trolleys are food trolleys, mobile pieces of furniture and mobile workbench carts.
  • the trolley is provided with "hubless” wheels of a particular configuration, designated by reference 1, which wheels are designed so as to make the trolley sides accessible through the wheel as well as creating an interesting visual effect.
  • Fig. 2 illustrates the construction of the wheel and the means of mounting thereof to the trolley.
  • the wheel essentially consists of an outer annular member 3, an inner annular member 10 and a number of lateral mouldings 15.
  • Rolling elements 6 are provided by means of which the outer annular member is rotatably mounted for relative movement with respect to the inner annular member, thus allowing absorption also of laterally directed forces.
  • the rolling elements could be in the shape of balls, rollers or needle-shaped elements and they are contained in one or several races, two in number in the drawing figures.
  • Figs. 3 and 4 also show that the outer annular member is formed on its radially inner face with two races 4 and 5 and that the inner annular member is formed with two races 7, 8 on the radially outer peripheral face 9.
  • the outer annular member may be manufactured from a tubular blank from which a number of annular members are cut.
  • the material may be aluminium, steel or some other metal, or plastics.
  • the outer annular member may be cast from metal or plastics or be manufactured by some other well-known manufacturing process, such as pressing.
  • non-lubricated bearings may, as a rule, be used including rolling elements made from Delrin plastics, cf. ball bearing pulleys used in sailing-boats.
  • Important characteristics of the invention are that the inner annular member 10 is adapted to cooperate with a lateral moulding 15 and that these two elements are not proper hoops but may be fitted axially one into the other. Figs.
  • the manufacture of the helically wound blank preferably is effected by winding a lengths of plastics or metal sections onto a calibrating mandrel.
  • heat suitable for the material used preferably is supplied.
  • the heat treatment may be effected after cold winding or the section may be subjected to this treatment after the winding-on operation. Examples of suitable materials are aluminium or steel, which are extruded to form the sections, or plastics produced by any suitable method.
  • the helically wound blank is then cut into circular rings, each forming a complete circle.
  • One such ring including an inner annular member 10 may then be mated together with another ring fitted with a lateral moulding 15 in that the two rings are twisted together by intro ⁇ ducing an engagement rib 14 projecting from one side 13 of the inner annular member into a corresponding groove 16 formed in the lateral moulding 15.
  • the engagement rib 14 is dovetail-shaped in such a manner that in a direction radially inwards and outwards it presents two oppositely directed conical faces flaring outwards from the lateral face 13.
  • the groove 16 has a mating configuration so as to securely engage the dovetail-shaped rib 14 and in the two mating components the conical faces extend radially outwards and inwards in a mutually parallel relationship. In order to facilitate the fitting-together of the two components, groove 16 is slightly bigger than the dovetail rib 14.
  • the lateral moulding 15 is provided with threaded holes 17 into which fastening screws may be threaded so as to exert pressure on the inner annular member 10, forcing the inner annular member and the lateral moulding apart and thus their conical faces into contact with one another.
  • This arrangement is clearly shown in Fig. 2.
  • Fig. 2 likewise appears the manner in which the wheel 1 is mounted on the trolley 2. Since the engagement rib 14 extends along the entire peripheral perimeter of the inner anular member 10, one or several sections of the lateral moulding 15 may be applied in such a manner that they cover a smaller portion of the circumference or the entire circumference, various different intermediate positions obviously also being possible.
  • the wheel is attached to the trolley by means of screws 20 which are screwed into threaded holes 19 in the lateral moulding from the side face of the trolley.
  • screws 20 which are screwed into threaded holes 19 in the lateral moulding from the side face of the trolley.
  • the left wheel according to Fig. 1 is screwed onto the vertical trolley face 23 in this manner. Since the wheel itself obscures its means of attachment from view entirely, a visual effect is created when the wheel, seen from the side, appears to be suspended in the air.
  • the right-hand wheel is attached to the trolley vertically below the latter with the aid of an fastener bracket 21.
  • the latter is in turn screwed onto the trolley bottom 24 by means of screws 22, in this case shown in dash-and-dot lines.
  • the lateral moulding 15 is tightened by means of screws 20, shown in dash-and-dot lines, also in the case of the upper attachment.
  • Fig. 6 illustrates the case when the helically wound blank for the inner annular member 10 has not been 2017 P r V C m T m / t SoE E .9-,1/00801
  • assembly aids of a kind containing a number of rolling elements and arranged to feed the latter correctly into the gap between the end edges.
  • the upper moulding section is displaced towards the left so as to cover the joint, whereupon it is locked in position with the aid of fastening screws 19 which are tightened in the threaded holes 17, cf. Fig. 8.
  • the lower moulding section is placed in the desired position and fastened by means of screws.
  • Fig. 7 illustrates a somewhat different method of inserting the rolling elements.
  • the helically shaped inner annular member blank has been cut in such a manner that when the outer annular member is in position, one part is missing. The gap thus left between the two end edges of the inner annular member is used to insert the rolling elements.
  • a supplement part 27 of a particular design is put in position in the place of the missing part.
  • the upper moulding sec- tion 25 is pushed on top of the joint to keep the two ends of the inner annular member and the supplement part 27 in place.
  • the moulding section 25 is fastened by means of fastening screws 18 which are screwed into the threaded holes 17.
  • Fig. 8 wherein is also shown the manner in which the lower moulding section 26 is associated with the fastening bracket 21 with the aid of fastening screws 20 screwed into the threaded holes 19.
  • the rolling elements could also be inserted via the recesses of particular design formed in the lateral faces of the inner annular member 10. These recesses should be sufficiently shallow not to interfere with the regular function of the rolling elements. Likewise it is possible, after insertion of the rolling elements, to close the recesses by external means.
  • the construction means that, in the area of one or two joints in the inner member 10, the movement of the rolling elements will be interfered with to some extent. For this reason, these joints should normally be directed upwards, when the rolling elements are not exposed to load.
  • many of the com ⁇ ponents may be configured differently than shown in the drawing figures. For instance, a great many alternative shapes are possible for the engagement rib 14 and the recesses 16. Additionally, they may be reversed, the recess being formed on the inner member 10 and the projecting part being positioned in the lateral mould ⁇ ing 15.
  • the outer annular member 3 may be formed with different sectional heights, as indicated in phantom lines in Fig. 3.
  • the wheel may be provided with various kinds of dirt-guard seals as also with seals preventing lubricants from escaping.
  • the lateral moulding 15 may be provided with a seal or else a separate seal be secured with the aid of the engagement rib 14.
  • a separate engagement rib may be formed next to rib 14 as well as separate ribs on the opposite side of the wheel.
