Abstract
A lifting assembly for a chassis having structural members wherein the lifting assembly comprises a first lift handle sub-assembly and a second lift handle sub-assembly. Each lift handle sub-assembly includes a first lifting bracket slidably mounted to a first chassis structural member and a second lifting bracket slidably mounted to a second chassis structural member positioned from the first lifting bracket. A lift handle is attached at each end thereof to one end of the first and second lifting brackets. Attached to a second end of the first and second lifting brackets is a lower stop bar sliding within the chassis structural-members. Attached to the chassis structural members in the path of movement of the lower stop bar is a slide stop bar that establishes the limit of movement of the lift handle to a gripping position.
Claims13
A lift assembly retractably mounted within a chassis, comprising:
- a chassis having first and second structural members;
- a first lifting bracket slidably mounted to the first structural member;
- a second lifting bracket slidably mounted to the second structural member;
- a lift handle attached to the first and second lifting brackets;
- a lower stop bar attached to the first and second lifting brackets, the lower stop bar slidable within the chassis along with the first lifting bracket and the second lifting bracket, and
- a slide stop bar attached to the first and second structural members in a path of movement of the lower stop bar to limit movement thereof and thereby limit movement of the lift handle to a gripping position outside the chassis.
A lifting assembly comprising first and second lift handle sub-assemblies, each retractably mounted on opposite sides of and within a chassis, each lift handle sub-assembly comprising:
- first and second chassis structural members;
- a first lifting bracket slidably mounted to the first structural member;
- a second lifting bracket slidably mounted to the second structural member;
- a lift handle attached to the first and second lifting brackets;
- a lower stop bar attached to the first and second lifting brackets, the lower stop bar slidable within the chassis along with the first lifting bracket and the second lifting bracket;
- and
- a slide stop bar attached to the first and second structural members in a path of movement of the lower stop bar to limit movement thereof and thereby limit movement of the lift handle to a gripping position outside the chassis.
A lift assembly retractably mounted within a chassis, comprising:
- a chassis having a first structural member, a second structural member, a third structural member, and a fourth structural member;
- a first lifting bracket slidably mounted to the first structural member;
- a second lifting bracket slidably mounted to the second structural member;
- a first lift handle attached to the first and second lifting brackets;
- a first lower stop bar attached to the first and second lifting brackets, the first lower stop bar slidable within the chassis along with the first lifting bracket and the second lifting bracket;
- a first slide stop bar attached to the first and second structural members in the path of movement of the first lower stop bar to limit movement thereof and thereby limit movement of the first lift handle to a gripping position outside the chassis;
- a third lifting bracket slidably mounted to the third structural member;
- a fourth lifting bracket slidably mounted to the fourth structural member;
- a second lift handle attached to the third and fourth lifting brackets;
- a second lower stop bar attached to the third and fourth lifting brackets, the second lower stop bar slidable within the chassis along with the third lifting bracket and the fourth lifting bracket;
- and
- a second slide stop bar attached to the third and fourth structural members in a path of movement of the second lower stop bar to limit movement thereof and thereby limit movement of the second lift handle to a gripping position outside the chassis.
A lifting assembly comprising first and second lift handle sub-assemblies, each retractably mounted on opposite sides of and within a chassis, each lift handle sub-assembly comprising:
- first and second chassis structural members;
- a first lifting bracket slidably mounted to the first chassis structural member within the chassis;
- a second lifting bracket slidably mounted to the second chassis structural member within the chassis;
- a lift handle attached to the first and second lifting brackets;
- a lower stop bar attached to the first and second lifting brackets, the lower stop bar slidable within the chassis along with the first lifting bracket and the second lifting bracket;
- and
- a slide stop bar attached to the first and second chassis structural members along one side of the chassis and in a path of movement of the lower stop bar to engage the lower stop bar to distribute the weight of the chassis along the slide stop bar and to limit movement of the lower stop bar and thereby limit movement of the lift handle to a gripping position outside of the chassis.
A lift assembly retractably mounted in a chassis to chassis structural members, comprising:
- a first lifting bracket slidably mounted within the chassis to a first chassis structural member;
- a second lifting bracket slidably mounted within the chassis to a second chassis structural member;
- a lift handle attached to the first and second lifting brackets;
- a lower stop bar attached to the first and second lifting brackets, the lower stop bar slidable within the chassis along with the first lifting bracket and the second lifting bracket;
- a slide stop bar mounted within the chassis and attached to the chassis structural members in a path of movement of the lower stop bar to engage the lower stop bar and limit movement thereof and thereby limit movement of the lift handle to a gripping position outside the chassis structural members;
- and
- a side panel attached to the first chassis structural member and the second chassis structural member to enclose the first lifting bracket, the second lifting bracket, the lower stop bar and the slide stop bar within the chassis.
