Lightweight reinforced modular tubes of extruded plastic material are provided for the first stage of a trolley-type carry case, in combination with a locking mechanism, which facilitates effective extension and collapse of a multi-telescopic handle system. The tubes are made of extruded plastic material and include a pair of opposed metal strips having appropriately spaced and dimensioned apertures for reception of spring loaded locking pins of the telescopic system. The metal strips are respectively retained in position by a pair of radially extending elongated flange members which overlap marginal positions of the strips. The tubes and the metal strips can easily and quickly be cut to size to fit any size carry case. While the metal insert strips are preferably made of aluminum, any material stronger than the extruded plastic of the first stage tube can be used, i.e., steel, nylon, PVC, polyethylene, polycarbonate, or the like.

1. A trolley-type carry case having a three stage telescopic handle system, which comprises: a) a container for reception and retention of selected articles; andb) a telescopic handle system attached to said container, which comprises: at least a first stage extruded plastic tubular member, said extruded plastic tubular member defining a generally central tubular opening having an inner tubular surface, said extruded plastic tubular member having a pair of generally opposed reinforcement strips made of a material of strength greater than the material of said tubular member positioned on said inner tubular surface of said central tubular opening, each said reinforcement strip having a generally radially extending retention member positioned along each side and offset to form a generally hat-like cross-sectional shape, said retention member configured to retain said reinforcement strip in position adjacent the inner surface of said tubular member, each said reinforcement strip having a plurality of apertures of predetermined size and relative locations for reception of spring biased pins associated with a respective second and third stage members of said telescoping handle system. 2. A tube for a first stage of a telescopic handle system for a trolley-type carry case, which comprises: a) an elongated tubular member;b) at least a pair of opposed radially inwardly extending members extending from the inner surface of said tubular member, each said radially inwardly extending member being comprised of a generally circumferential flange member extending from the free end thereof and each said flange member facing the other so as to form a pair of opposed flange members which define a space therebetween for reception of an elongated reinforcement strip; andc) at least one elongated reinforcement strip positioned between said flange members and retained in position against the inner surface of said elongated tubular member, said elongated reinforcement strip being of a material which adds strength to the said elongated tubular member, said elongated reinforcement strip having a plurality of apertures dimensionally and relatively spaced for reception of spring biased locking pins associated with a locking device for retaining respective associated stages of a telescopic handle in either the withdrawn or the extended position when said pins enter predetermined respective apertures in said reinforcement strip. 3. A telescopic handle assembly for a trolley-type carry case, comprising: a first stage tubular member, said generally tubular member being made of an extruded plastic material and defining a generally central elongated tubular opening;a pair of opposed reinforcement strips held within said generally tubular opening of said first stage tubular member, said reinforcement strips dimensioned to extend generally along a length of said first stage tubular member thereof, said reinforcement strips being of a material of strength generally greater than the strength of the material of said first stage tubular member, each said reinforcement strip having a plurality of apertures of predetermined size and relative positions for respective reception of spring biased pins associated with respective second and third stage sections of the telescopic handle assembly for respective retention of the handle assembly in the respective collapsed and extended positions; andretaining members positioned within said generally tubular opening and along the length of said first stage tubular member, said retaining members formed of at least a pair of opposed radially inwardly extending members extending from an inner surface of said first stage tubular member, each said radially inwardly extending member having a generally circumferential flange member extending from the free end thereof and each said flange member facing the other so as to form a pair of opposed flange members which define a space therebetween for reception and retention of each said reinforcement strip. 4. The telescopic handle assembly according to claim 3, wherein said extruded plastic tubular member comprises a plurality of radial plastic ribs extending inwardly of said inner surface to provide structural support to said tubular member. 5. The telescopic handle assembly according to claim 4, wherein said handle system comprises a pair of said first stage tubular members. 6. The telescopic handle assembly according to claim 5, wherein a locking system is provided to extend and lock second and third stage sections in selected portions. 7. The telescopic handle assembly according to claim 6, wherein the third stage tubes are connected by a gripping handle and said locking system includes a release button in said gripping handle, said release button connected to respective cables and spring biased pins adapted to selectively lock and release the second and third stage tubes in selected positions. 8. The telescopic handle assembly according to claim 7, wherein said second and third stage tubes are aluminum. 9. The telescopic handle assembly according to claim 8, wherein each said tubular member is polyvinyl chloride and said reinforcement strips are aluminum. 10. A telescopic handle system for a trolley-type carry-case, comprising: at least a first stage extruded plastic tubular member, said extruded plastic tubular member defining a generally central tubular opening having an inner tubular surface;a pair of generally opposed reinforcement strips made of a material of strength greater than the material of said tubular member, said pair of generally opposed reinforcement strips being positioned on said inner tubular surface of said central tubular opening, each said reinforcement strip having a generally radially extending retention member positioned along each side and offset to form a generally hat-like cross-sectional shape, said retention member configured to retain said reinforcement strip in position on the inner surface of said tubular member,each said reinforcement strip having a plurality of apertures of predetermined size and relative locations for selective reception of spring biased pins associated with a respective second and third stage members of said telescoping handle system. 11. A tubular member for the first stage of a telescopic handle system for a trolley-type carry case, which comprises: a) a generally elongated tubular member made of an extruded plastic material and having a generally central elongated opening; andb) a plurality of radially inwardly extending members which are coextruded with said generally tubular member, at least certain of said radially inwardly extended members providing reinforcement to said extruded tubular member against forces applied thereto during use, at least certain of said radially inwardly extending members having generally opposed circumferential members at the radially inwardmost free end thereof and facing each other to form a pair of flanges which respectively overlay at least a marginal portion of a respective reinforcement member to retain said respective reinforcement member in position within said generally central opening, said respective reinforcement member having a plurality of apertures of predetermined size and relatively spaced positions for reception of spring-biased pins associated with a release and locking mechanism for a multi-stage telescopic handle system. 12. The trolley-type carry case according to claim 1, wherein said container is an article of luggage.
