Definitions

  • the present invention relates to an assembly device of a wheel in the field of application of the roller skate in line.
  • a roller skate in line 1 consists of part of shoe 2 referred to front and heel on an inverted U-shaped chassis 3 comprising side plates 4, 5 substantially parallel between which are assembled a series of wheels 6 arranged in an aligned configuration.
  • the wheel mounting must be designed so that allow its free rotation around two elements of ball bearings 60, 61, generally mounted flush with each side of the wheel in two concentric cages.
  • the rolling elements are generally kept spaced apart by a central bracing element 62 in the form of a ring.
  • a fastening system 7 formed of a female element 71 provided with a cylindrical rod constituting the main axis of rotation 8 of the wheel and a male element 70 provided with a portion of rod external threaded diameter smaller than the external diameter of the rod of female element 71, cooperating with a portion internal threaded complementary to the female element like the shows in detail Figure 3.
  • Each part 70, 71 has a head supported respectively on each edge of the flanges lateral.
  • the head of the female element may have lateral notches resting on the flange for locking in rotation during tightening; while the head of the male element includes tightening engagement means allowing use a suitable key 9 such as an awl key, for example.
  • a suitable key 9 such as an awl key, for example.
  • Such fastening system is not completely satisfactory because it does not allow easy and rapid assembly of wheel. Indeed, due to its diameter, the rod element female is delicate to introduce in the axis of the wheel where it meets the bracing element that is often found slightly offset due to its floating mounting in the central part of the hub. To successfully introduce the rod, the bracing element must be positioned so centered by shaking the wheel, for example.
  • US patent 5,513,861 proposes a system of this type with a special mounting tool which facilitates the introduction of the female part by pulling it in the hub axis using a suitable tool.
  • the assembly remains complex and delicate to manage industrially.
  • a another disadvantage of such a system is that it includes two moving parts in translation which then require a maintenance of each of them during assembly and makes it difficult a series mounting of several wheels simultaneously.
  • a more recent assembly method illustrated in FIGS. 4 and 5, applied to machined / extruded frames, consists of screwing a part of male rod resting on the edge of a first flange directly in the second opposite flange.
  • the part of rod includes a threaded end portion which provides connection with a portion of thread in the hole of the second flaccid.
  • This system facilitates the passage of the rod part in the axis due to the smaller section of its end threaded which ensures the centering of the bracing element center of the hub.
  • this system is exclusively reserved for machined metal frames with sufficient flank thicknesses.
  • shape constraints and constraints do not allow to obtain a length of sufficient thread in the flange that meets the requirements minimum mechanical strength characteristics of the fixation.
  • Patent application DE 197 10 297 A1 from Textron Inc. relates to a device which includes a first main element comprising a rod serving as an axis of wheel and a smaller diameter threaded end which cooperates with a threaded dowel provided with a slot longitudinal which expands during the screwing of the first element.
  • a threaded dowel provided with a slot longitudinal which expands during the screwing of the first element.
  • the present invention proposes to remedy the disadvantages and provide a system that facilitates mounting of a wheel on an inline skate chassis not comprising only one moving part when mounting the central rod forming the wheel axle, easy to insert without risk of blocking and requiring the use of only one tool Tightening.
  • Another object is to propose a device which adapts to any type of chassis, and preferably to chassis obtained by the stamping technique.
  • the insert does not constitute a movable part of the fixing device because it can be pre-assembled so independent on its flange before the element is introduced male fastening including the axis of rotation axis of the wheel. This therefore facilitates the mounting of the wheel in general, and the introduction of the wheel axle rod, in particular.
  • the insert also remains independent of the flange; what has the advantage that it can then be adapted to any type of chassis whatever their dimensional constraints and shape, including those obtained by stamping sheet metal metallic. So, being a separate part of the chassis, it can be designed to be able to offer a thread length sufficient to reduce the risk of breakage or loosening.
  • the own locking means in the position of the insert comprises means for forcibly mounting the insert fixing in the first hole of said flange. So the insert can be pre-assembled without the need for special tools.
  • the mounting can be done with the press for example.
  • Many inserts can be mounted on the same flange at the same time during an operation preceding that of mounting the wheel.
  • the present invention is relates to a generally designated assembly device by the reference 10.
  • the device according to the invention can adapt to an inline skate of the type shown in the Figure 1, for example. So the same references are repeats to reduce the number of references and facilitate reading.
  • the assembly device 10 therefore comprises a elongated, light and relatively rigid chassis 3 provided with side plates 4, 5.
  • the chassis must have stiffness and mechanical strength characteristics important to withstand bending and twisting forces applied while remaining light enough to reduce the fatigue of the skater.
  • the chassis flanges are generally arranged substantially parallel to each other. They are provided with holes 40, 50 aligned coaxially along the axis transverse I.
  • the wheel 6 which comprises a central main part 63, identical side rolling elements 60, 61 and one element central bracing 62.
  • the bearing elements are formed of external rings 600, 610 and internal rings 601, 611 between which is arranged a concentric series of balls 602, 612.
  • the central part is composed, so known, from a hub 64, generally made of rigid plastic surrounded circumferentially from a tread 65 in polyurethane or rubber intended to come into contact with floor.
  • the hub 64 includes a cavity 66 extending transversely right through 1st axis I.
  • the cavity includes two opposite concentric cages (not referenced) of sufficient diameter for tight engagement of bearings 60, 61 and a central annular shoulder 662 serving as a stop for the outer rings 600, 610 of the bearings 60, 61. Between the bearings is positioned the tubular bracing element 62 whose external diameter in contact is approximately same diameter as that of the internal rings 601, 611 of bearings to allow their proper functioning. We understand therefore that in FIG. 7 that the bracing element 62 is floating and offset by gravity in the cavity 66 before the fixing device is installed.
  • the fixing device 7 consists a male fastening element 70 and a fastening insert female 71.
  • the male fixing element comprises a head 700 extended by a main portion or cylindrical rod 701 smooth serving as a wheel axle.
  • the cylindrical rod extends by a short end portion 702 comprising a thread.
  • the short portion 702 has a section substantially less than the portion of rod to facilitate element engagement male in the central cavity; which causes the self-centering of bracing element 62 and reduces the risk of blockage during assembly.
  • the female part of the fixing element is an insert 71, independent of the flange, in the form of a circumference ring closed and not expandable unlike the known system DE 197 10 297 A1. It includes an external support portion 710 which carries its own means of locking in rotation and in translation when the insert is in abutment on the edges 41 of the hole 40 in the flange.
  • the insert can thus be mounted separately from the male fastener forming the rod wheel axle; which has many advantages, between other that of facilitating the introduction of the axis rod of wheel without risk of jamming or blocking, or that of reduce the number of moving parts when mounting the axle wheel.
  • the locking means comprise mounting means in force of the fixing insert in the hole in the flange.
  • these means include mechanical means of knurling or spline type 711.
  • the force fitting of the insert can be made to the press, for example, or any other appropriate means.
  • the means may include a separate layer of material compressible and high coefficient of friction engaged with the edges of the flange hole.
  • the insert is provided with an internal part 720 comprising a complementary thread of the threaded portion 702 of the element male fastening.
  • the use of an independent insert also has the advantage of allowing you to choose a length appropriate thread regardless of constraints geometric and dimensional linked to the chassis. Indeed, in the case shown in Figures 7 and 8, the chassis comprises flanges obtained by stamping a sheet metal plate metallic. Such a process is described in detail in the application. European patent EP 0774 283 A1 the entire content of which is included in this application by reference. The process according to the aforementioned application makes it possible to reconcile the characteristics of mechanical strength, adaptability, flexibility realization, lightness and low manufacturing cost by compared to traditional processes.
  • the process consists of cut a corresponding shape from a metal side substantially in the developed form of at least part of the chassis and, to produce at least one stiffening rib by stamping in the chassis part.
  • the rib gives, due to its shape and the work hardening of the material due to the deformation, a substantial increase in mechanical characteristics.
  • the coaxial holes of the flanges are made by deformation and displacement of the metal to form a chimney during the stamping operation.
  • the coaxial holes 40, 50 are delimited by a chimney 42, 52 extending towards the inside of the chassis in the direction of the wheel.
  • the chimney forms a rim bearing on the ring internal 601, 611 of each bearing so as to maintain appropriate distance to the internal surface 43, 53 of each flaccid.
  • the chimney includes a first flared portion 410 and, optionally, a second portion cylindrical 411 extending the first portion towards the interior towards the wheel.
  • the flared portion results essentially the process of manufacturing the flange which does not admit the formation of sharp angles but imposes the formation bending or shaping radii of the material.
  • the external portion support 710 of the insert also includes a shoulder part substantially flared 712 complementary in shape to a first flared portion 410 of the edge of the hole.
  • the internal part of thread 720 is preferably of a length greater than the length of the first flared portion 410 of the hole, so as to extend it inwards towards wheel.
  • Another advantage is related to the complementary nesting flared shapes of the insert and the edge of the participating hole quick and correct positioning by self-centering the insert in the hole and facilitates force pressing in the hole.
  • the female fixing insert 71 comprises a surface transverse external 73 substantially flush with the external surface 44 of the lateral flange 4 or slightly in inward withdrawal of hole 40 relative to said external surface 44 after tightening of the fixing device (figure 8).
  • the male fastening element 70 also comprises a shoulder part of flared shape 703 which rests on a substantially flared part 510 of the edge 51 of the hole 50.
  • the shoulder portion 703 ends with a surface transverse external 704 substantially flush with the surface external 54 of the second flange 5 or slightly recessed towards the interior of the hole with respect to said external surface of the second flange after tightening of the fixing device.
  • FIG. 10 illustrates a variant of the invention.
  • the side flanges 4, 5 of the chassis can be made without ledge or internal chimney.
  • the insert includes a flared portion 712 and a cylindrical portion 713 therein connecting; the cylindrical portion 713 extending in protrusion beyond the internal surface 43 of the first flange of to serve as a means of bridging by keeping distance the wheel from the internal surface of the flange.
  • the bracing can be carried out on the other side by insertion of a 530 washer of thickness and diameter appropriate.
  • Such a chassis can be obtained by any type of technical and any suitable rigid material.
  • the chassis can be of the extruded metal type and machined in the mass. It can also be obtained by cutting / stamping flanges and drilling coaxial holes in the flanges. It can also be obtained in reinforced plastic or not by the injection technique.
  • FIGS 11 to 13 show another variant of the invention for an application intended for chassis in plastic materials.
  • the female fixing insert 71 is formed of a tubular portion 714 extending transversely along of axis I and comprising an internal surface provided with a thread.
  • the tubular portion is connected externally to a head portion 715 comprising a flat external surface and a support portion or internal surface provided with a plurality of teeth 716, 716a, 716b, 716c, four in number for example.
  • the teeth form the own locking means in the position of the insert.
  • the insert is mounted on the edges of the flange by pressing so that the teeth fit into the material of the frame. A press fitting of the inserts is thus easily conceivable.
  • tubular portion 714 extends projecting beyond the internal surface 43 of the first flange so as to serve as means of bracing by keeping the wheel of the internal surface of the flange.
  • a washer 530 serves as a bracing means.
