Abstract

A platform extension mechanism includes at least a bumper, a rolling bearing, an adjuster, and an axle. The axle has a first end surface and a second end surface. The axle is elongated along a first axis. The axle includes interior wall portions that define a slot from the first end surface to the second end surface. The axle is structured to receive the bumper and the adjuster via the slot. The axle is structured to support the bumper and the adjuster in relation to a platform and a structural channel. The axle includes a mounting portion and a shaft portion. The mounting portion has a flange with a first side and a second side. The first side of the flange is mountable to a sidewall portion of the platform. The shaft portion protrudes outward from the second side of the flange. The shaft portion has a peripheral portion that is structured to support the rolling bearing at a designated location along the first axis and enable the rolling bearing to move along the structural channel. The shaft portion is structured to support the bumper and the rolling bearing in a coaxial arrangement. The adjuster is aligned with the bumper and configured to adjust a position of the bumper along the first axis of the axle.

First claim

What is claimed is:

1. A platform extension mechanism for a platform with a structural channel, the platform extension mechanism comprising:
a bumper configured to confront a surface of the structural channel;
a rolling bearing configured to move along the structural channel; and
an axle having a first end surface and a second end surface, the axle being elongated along a first axis, the axle including interior wall portions that define a slot from the first end surface to the second end surface, the axle being structured to receive the bumper in the slot and support the bumper in relation to the platform and the structural channel, the axle including:
a mounting portion having a flange with a first side and a second side, the first side of the flange being mountable to an inner side of a sidewall portion of the platform; and
a shaft portion protruding outward from the second side of the flange, the shaft portion having a peripheral portion that is structured to support the rolling bearing at a designated location along the first axis and enable the rolling bearing to move along the structural channel,

wherein,
the shaft portion is structured to support the bumper and the rolling bearing in a coaxial arrangement.

2. The platform extension mechanism of claim 1 , wherein:
a dimension of the axle along the first axis is greater than a dimension of the bumper along the first axis; and
the axle is structured to support the bumper such that the bumper protrudes outward from the second end surface of the axle.

3. The platform extension mechanism of claim 1 , wherein:
the axle comprises metal; and
the bumper is an elongated member that comprises plastic.

4. The platform extension mechanism of claim 1 , further comprising:
an adjuster configured to adjust a position of the bumper along the first axis of the axle,
wherein,
the axle is configured to receive the adjuster via the slot and support the adjuster via the interior wall portions such that the adjuster is aligned with the bumper.

5. The platform extension mechanism of claim 4 , wherein:
the axle includes a boss that protrudes outward from the first side of the flange and along the first axis;
the boss includes the first end surface with an opening to the slot; and
the adjuster is accessible via the boss from an outer side of the sidewall portion of the platform when the flange is mounted to the inner side of the sidewall portion of the platform.

6. The platform extension mechanism of claim 1 , wherein:
the shaft portion includes a first shaft section and a second shaft section;
the first shaft section protrudes outward from the second side of the flange;
the second shaft section protrudes outward from the first shaft section such that the first shaft section extends between the flange and the second shaft section;
the designated location is located along an outer surface of the second shaft section; and
a dimension of the first shaft section along a second axis is greater than a dimension of the second shaft section along the second axis, the second axis being perpendicular to the first axis.

7. The platform extension mechanism of claim 6 , wherein:
the first shaft section is structured to establish a predetermined distance between the flange and the designated location for the rolling bearing;
the shaft portion includes a first shoulder that is provided at a transition between the first shaft section and the second shaft section, the first shoulder being configured to retain the rolling bearing at the designated location along the axle; and
the second shaft section includes a groove configured to receive a fastener that provides a second shoulder to retain the rolling bearing at the designated location along the axle.

8. A platform assembly comprising:
a platform including at least a work surface portion and a sidewall portion;
a frame configured to support the work surface portion and the sidewall portion;
a structural channel mounted on the frame;
a platform extension mechanism including
a bumper configured to confront a surface of the structural channel;
a rolling bearing configured to move along the structural channel; and
an axle having a first end surface and a second end surface, the axle being elongated along a first axis, the axle including interior wall portions that define a slot from the first end surface to the second end surface, the axle being structured to receive the bumper in the slot and support the bumper in relation to the platform and the structural channel, the axle including:
a mounting portion having a flange with a first side and a second side, the first side of the flange being mountable to the sidewall portion of the platform; and
a shaft portion protruding outward from the second side of the flange, the shaft portion having a peripheral portion that is structured to support the rolling bearing at a designated location along the first axis and enable the rolling bearing to move along the structural channel,

wherein the shaft portion is structured to support the bumper and the rolling bearing in a coaxial arrangement.

9. The platform assembly of claim 8 , wherein:
a dimension of the axle along the first axis is greater than a dimension of the bumper along the first axis; and
the axle is structured to support the bumper such that the bumper protrudes outward from the second end surface of the axle.

10. The platform assembly of claim 8 , wherein:
the axle comprises metal; and
the bumper is an elongated member that comprises plastic.

11. The platform assembly of claim 8 , further comprising:
an adjuster configured to adjust a position of the bumper along the first axis of the axle,
wherein,
the axle is configured to receive the adjuster via the slot and support the adjuster via the interior wall portions such that the adjuster is aligned with the bumper.

12. The platform assembly of claim 11 , wherein:
the axle includes a boss that protrudes outward from the first side of the flange and along the first axis;
the boss includes the first end surface with an opening to the slot;
the boss is structured to mate with a through-hole of the sidewall portion of the platform; and
the adjuster is accessible via the boss from an outer side of the sidewall portion of the platform when the flange is mounted to an inner side of the sidewall portion of the platform.

13. The platform assembly of claim 8 , wherein:
the shaft portion includes a first shaft section and a second shaft section;
the first shaft section protrudes outward from the second side of the flange;
the second shaft section protrudes outward from the first shaft section such that the first shaft section extends between the flange and the second shaft section;
the designated location is located along an outer surface of the second shaft section; and
a dimension of the first shaft section along a second axis is greater than a dimension of the second shaft section along the second axis, the second axis being perpendicular to the first axis.

14. The platform assembly of claim 13 , wherein:
the first shaft section is structured to establish a predetermined distance between the flange and the designated location for the rolling bearing;
the shaft portion includes a first shoulder that is provided at a transition between the first shaft section and the second shaft section, the first shoulder being configured to retain the rolling bearing at the designated location along the axle; and
the second shaft section includes a groove configured to receive a fastener that provides a second shoulder to retain the rolling bearing at the de
