Abstract
A conversible bicycle rear article carrier attachment that will fit on most conventional rear article carriers, particularly designed for folding/20" wheeled bicycles, is disclosed. Foremost, this attachment exploits the hereto untapped vertical space immediately behind the seat post on folding bikes, enabling the carrying of a single, large duffel type bag or suitcase, with particular aim at the touring market. Alternatively, the unit improves cargo carrying capacity for urban commuting, permitting the secure carrying of large box-like containers. The expansible features function in vertical, lateral and longitudinal directions. In collapsed mode the unit maintains a streamlined position relative to the existing main carrier.
Description
Background of the Invention 1. Field of the Invention:
1-001] This invention relates to bicycle cargo racks, bicycle article carriers, bicycle trailers, hitches and related cargo carrying methods.
1-001] This invention relates to bicycle cargo racks, bicycle article carriers, bicycle trailers, hitches and related cargo carrying methods.
2. Prior Art [002] Since the inception of the rear article carrier, a variety of cargo expansion adaptations have been developed ranging from collapsible baskets, platform enlargements, platform outriggers and carrier frame modifications to enhance pannier attachment.
(003] A number of existing art examples that expand the capacity of the rear article carrier can be referenced. US Patent 8,910,842 B2 employs an outrigger system, while US Patent 3934770A comprises collapsible baskets.
(further references to follow) Summary of the Invention [0/0] The impetus for this invention is based on the premise that a single piece of lugge/container is a superior method for travel with respect to ergonomic simplicity, organizational efficiency, security and elegance.
[011] The placement of a single luggage type container on conventional bicycles is problematic in two respects: top heaviness/
wobbliness if placed on carrier platform, lopsidedness/imbalance if placed on the side. Both methods are limited in volume capacity.
[012] Whereas the industry has recognized the need for the single-load cargo method in the form of trailers, the two pannier/sack method employed on both on rear and front carriers continues to dominate the touring market.
[013] While the trailer solves an ergonomic/organizational problem, it creates another in terms of weight, space occupation and manueverability.
[014] In the context of the folding bicycle which this invention addresses, it is interesting to note that both pannier style and trailer method of cargo carrying are the accepted norms.
As will become evident upon further examination, this invention eliminates the need for both trailer and panniers on folding/20"
wheeled bicycles, comfortably permitting a single load cargo volume upwards of 75 liters.
Brief Description of the Drawings FIG. 1 shows a top view of unit in collapsed mode FIG. 2 shows an isometric left view in collapsed mode FIG. 3 is top view with side fences raised FIG. 4 is a left isometric view with side fences raised FIG. 5 is a top view with fences and telescoping tail piece fully expanded FIG. 6 is an isometric bottom view of fastening details FIG. 7 shows spring pin stop/lock mechanism for telescoping tail piece Detailed Description of the Invention [015] FIGS. 1 through 7 show the primary elements and components of this invention:
outer platform sides-- tubular metal 3 hinged side fences tubular metal 13 connected to outer platform 3 via flat metal channel bar 22 hinged side fences 13, revolving around tube 15, locked at 180 degree positions via pin, hole and spring, 19, 17, 14 hinged side fences 13 attached to slotted flatbars 21, 23, that slide across channeled flatbar 22, tightened with broad flat head knob/bolts 25 crossbars 7 connecting main frame 3 with crossbar bottom pieces 8 that attach to bicycle carrier platform 2 with bolts 11 telescoping tubular tail piece 9 via slotted tube 5 on outer platform tube 3, tail piece cross bar 10, tail piece fence 12 tail piece spring lock mechanism 26, 27 (further details to follow)
