Definitions

the present invention relates to a frame for an in-line roller skate according to the preamble of claim 1, and also to a method for manufacturing such frame according to the preamble of claim 8.
a frame and such a method are known from US-A-5 388 846.
This prior art document discloses the manufacture of a frame for an in-line roller skate starting from an extruded aluminium section including two parallel solid side walls and three transverse members interconnecting the side walls.
the top transverse member is intended to form the support for the heel of the shoe
the middle transverse member is meant to form the support for the toe of the shoe
the bottom transverse member forms bridges connecting the side walls at locations between holes formed in the side walls for accomodating the wheels.
the present invention aims to solve the abovementioned problem.
a further object of the present invention is to provide an in-line roller skate that is light and rigid, in particular that has a considerable torsional and/or bending stiffness.
the invention aims to provide a suitable production method.
the present invention provides a frame for an in-line roller skate according to the preamble of claim 1, which is characterized in that each side rail of the frame has one or more internal chambers, formed during the extrusion of the section and extending substantially along the length of the side rail.
the invention therefore proposes not making the side rails with a solid cross section, as in the case of the prior art frame disclosed in US-A-5 388 846, but with internal chambers, so that a double walled or multiple-walled construction of each side rail is obtained.
the section preferably from light metal, by means of a suitable extrusion die, one or more of such axial chambers can be formed in a relatively simple manner into a side rail.
each side rail preferably forms a closed peripheral wall around the chamber along the entire length of that chamber.
each side wall may form a closed peripheral wall along the entire length of the chamber around at least one of the internal chambers.
the side rail then comprises, as it were, a tube extending along the length thereof and free from openings in the periphery. Such a tube has a great stiffness and is light.
each side rail is provided with one or more holes in a bottom edge strip thereof, for wheel shafts belonging to the wheels, the side rail being of a solid construction in the region of the bottom edge strip.
the side rails are connected only by transverse elements obtained by working a top and a bottom transverse member formed between the side rails during the extrusion.
the top transverse member is then preferably subjected to a finishing operation, in order to form the heel support for the shoe
the bottom transverse member is subjected to a finishing operation, in order to form the support for the toe of the shoe.
the presence of one or more chambers extending in the longitudinal direction in each side rail means that the stiffness thereof increases to such an extent that, compared with the known in-line roller skate mentioned earlier, it is possible to omit a third transverse member during the extrusion. This produces a considerable saving in the finishing operation of the extruded section.
the present invention also provides an in-line roller skate including a frame of the type defined above, and a method for manufacturing such a frame.
Figures 1-4 show a frame 1 of an in-line roller skate, which is not shown in any further detail.
the frame 1 is equipped for fixing wheels - in this example five - in a line one after the other.
the roller skate further comprises a shoe (not shown), the frame 1 being mounted in the longitudinal direction under the shoe, possibly by means of a hinged connection.
the frame 1 is manufactured by first extruding an elongated section, for example made of aluminium, an aluminium alloy or another suitable material.
the basic shape of the extruded section can be seen in Figure 2.
the section has two substantially parallel side rails 3, 4 situated at a distance from each other, and also a top transverse member 5 and a bottom transverse member 6.
the side rails 3, 4 project under the bottom transverse member 6.
the extruded section is subjected to one or more material-removing finishing operations, in order to obtain the frame 1 shown in Figures 1-4.
a support 7 for the heel of the shoe is made from the top transverse member 5, the part of the bottom transverse member 6 situated below it forming an additional transverse member 8 in said heel support 7.
a support 9 for the toe of the shoe is formed from the bottom transverse member 6.
the side rails 3, 4 are not made with a solid cross section, but are each provided with an internal chamber 10, 11 extending substantially along the entire length of the side rail 3, 4.
the chambers 10, 11 form a cavity in the side rail with a greater height than the width of the cavity.
the chambers 10, 11 provide, as it were, a double-walled construction of the side rails 3, 4.
each side rail 3, 4 it is very advantageous for each side rail 3, 4 to form a closed peripheral wall in that chamber 10, 11 along the entire length thereof.
a tubular part with closed peripheral wall that has great stiffness and is low in weight can thus be seen in each side rail 3, 4.
transverse openings 13, 14 are also formed in the side rails 3, 4, at the position of the heel support and the toe support. Said transverse openings 13, 14 are not in communication with the chambers 10, 11, in order to ensure in this way that the peripheral wall around said chambers 10, 11 is left intact.
Each side rail 3, 4 is further provided with one or more holes 17, 18 in a bottom edge strip 15, 16 thereof, for wheel shafts belonging to the wheels.
the side rails 3, 4 are made of a solid construction in the region of the appropriate bottom edge strip 15, 16, so that a stable base is provided for fixing the wheel shafts thereon.
one or both axial ends of the chambers 10, 11 are sealed off.
the seals can be loose stops that prevent dirt and the like from entering the chambers.
ends of the chambers can also be sealed off by a stop immovably connected to the side rail 3, 4, for example, a welded stop, so that the shut-off stop contributes to the stability of the side rail 3, 4.
