摘要:
A bag mounted with casters has a bag body (3) attached to a base frame (1) mounted with the casters (6) at four corners of bottom surface thereof. The base frame includes a loading table (2), and vertically extensible rods (5) with a grip (4) mounted at upper ends thereof. The extensible rods are fixed on one side of the loading table so as to stand on their own. Further, when the grip (4) is raised, the extensible rods (5) are curved or tilted so that the grip moves from the one side toward the middle of the loading table. The extensible rods are secured at a position in a retracted state by stoppers so that the grip is positioned at upper portion of the bag body or above the bag body, and are secured at a position by the stoppers in an extended state so that a height of the grip from bottoms of the caster is in a range of 60 to 100 cm.

A bag with caster wheels includes a base frame 1 having caster wheels 6 and a main bag 3. The base frame 1 includes a stand 2 mounting the main bag 3 thereon and telescopic rods 5 joined on one side of this stand 2 or between both sides. The stand 2 includes supporting cylinders 7 into which the telescopic rods 5 are inserted to be joined. The supporting cylinders 7 are arranged between the caster wheels 6 provided at four corners of the stand 2, and are projected in a lower surface of the stand 2, so that a projection height (d) thereof is made lower than a height (h) of the caster wheels 6. In lower surface projected parts 7A of the supporting cylinders 7, reinforcement walls 8 joined to the lower surface of the stand 2 are provided. The reinforcement walls 8 are arranged between the caster wheels 6 and in a posture oriented in a lateral direction of the stand 2. In this bag, the supporting cylinders 7 are joined to the stand 2 while being reinforced by the reinforcement walls 8, and lower ends of the telescopic rods 5 are joined to these supporting cylinders 7.

A bag is wheeled in an upright orientation on casters (1) on its bottom of by using a grip. A shaft (9) is coupled to a wheel (6) by one bearing (8). The ends of the shaft (9) are secured to the yoke (7) coupled to the bag portion (3). An outer ring (8B) of the bearing (8) is fitted in a fit-in groove (15) arranged at the center of the wheel (6). The outer diameter (A) of the shaft (9) is smaller than the inner diameter (B) of an inner ring (8A), and spacer pipes (17) are inserted into the inner ring (8A). Insertion portions (17B) of the spacer pipes (17) with a smaller outer diameter are attached to the inner ring (8A). Stopper portions (17A) with a greater outer diameter are arranged between the inner ring (8A) and the yoke (7) to hold the bearing (8).
摘要:
In a stick mounted with casters of the invention, a lower end of a stick main body (1) in which extensible vertical rods (5) are connected to both ends of a grip (4) extending in a horizontal direction is connected to a rectangular horizontal loading table (2) which makes the vertical rods (5) to be self-standing through casters (6) fixed at four corners of a lower face of the horizontal loading table (2), and a bag (3) is detachably attached on the horizontal loading table (2). The outer diameter of a wheel (10) of the caster (6) is 30 to 60 mm, and the caster (6) is attached to the horizontal loading table (2) such that a rotational shaft (13) can rotate in the horizontal plane. The grip (4) of the stick main body (1) extends along a longitudinal direction of the horizontal loading table (2). The vertical rods (5) are curved or tilted in a direction of placing the grip (4) at a central section of the horizontal loading table (2).

A base-and-frame assembly (1) for the wheeled luggage includes: a platform (102) having a carriage surface (2) for detachably carrying a separable bag (3) thereon; and an extendable rod (5) connected to the support tube (7) in a self-standing manner and having a grip (4) connected at an upper end, and being stopped by a stopper (15) at an extended position. The platform (102) is provided with a latitudinal reinforcement rib (112A) integrally formed below a planar carriage plate (9) with its top face serving as the carriage surface. In a horizontal plane including such surface, the latitudinal reinforcement rib (112A,112B) extends in a lateral direction orthogonal to the grip, protruding on a bottom face of the carriage plate (9). A reinforcement protrusion (108) is integrally formed with the latitudinal reinforcement rib (112A), protruding downwardly at an area below the support tube (7).

摘要:
The main bag stands independently and moves via free swiveling caster wheels (1) at four corners. A free swiveling caster wheel (1) is provided with a wheel (6), a yoke (7) connected to the wheel (6) in a manner allowing the wheel (6) to rotate, a radial bearing (8) with its outer ring (8B) connected to the yoke (7), a swivel shaft (9) connected to the inner ring (8A) of the radial bearing (8), and a mount (10) which holds the upper end of the swivel shaft (9) fixed. The rotation axis (11) of the wheel (6) is disposed with eccentricity with respect to the swivel axis m, which is the center of rotation of the swivel shaft (9), allowing the yoke (7) to swivel. The yoke (7) and mount (10) have a bend prevention gap established between mutually opposing surfaces in close proximity. When a bending impact load acts on the swivel shaft (9), the yoke (7) and mount (10) press against each other at the bend prevention gap (15) to support the bending impact force.
