摘要:
An engine stand including a cradle assembly configured to support an engine assembly and a dolly configured to support the cradle assembly. The cradle assembly includes an upper frame assembly including a first frame member and a second frame member each fixedly coupled to a third frame member, a protrusion coupled to and extending substantially vertically upward from the first frame member, and a rest coupled to the second frame member, the rest having an engagement surface shaped to correspond to a shape of an exterior surface of the engine assembly. At least one of the first frame member, the second frame member, and the third frame member define an aperture configured to receive a fork from a lift device.

An exoskeleton includes a first link that pivots in a transverse plane about a first vertical axis and a second link that pivots in a transverse plane about a second vertical axis. The second link is coupled to the first link. An arm support assembly is coupled to the second link and pivots about a horizontal axis. The arm support assembly includes a spring that generates an assistive torque that counteracts gravity. The arm support assembly provides the assistive torque to an arm of a wearer to support the arm of the wearer. The arm support assembly further includes a cam profile and a cam follower. Contact between the spring, cam follower and cam profile determines an amount of the assistive force provided by the arm support assembly. A cuff is coupled to the arm support assembly and the arm of the wearer.

The versatile modular home and garden kit includes multiple platform pieces and a variety of support posts for use in connecting the platform pieces together to form the construction of an unlimited number of structural, storage, garden, or entertainment uses for the home and garden. The versatile modular home and garden kit pieces assemble without the use of tools or screws by easily sliding an end of a platform piece into one side of the support posts which makes use of a plurality of unique trapezoidal grooves.

A jack stand apparatus has a frame having a first portion and an outwardly extending second portion, a barrel affixed to the outwardly extending portion so as to have a generally vertical longitudinal axis, a jack screw threadedly received by the barrel, and a plurality of caster wheels removably affixed to the frame. The barrel has an outer end extending outwardly for a first distance from the first portion of the frame. The plurality of caster wheels support the frame for a second distance from a level of the bottom of the caster wheels. The first distance is no more than the second distance. A support head is affixed to an end of the jack screw opposite the barrel. The frame is invertible relative to the caster wheels such that in one position the barrel extends upwardly from the frame and a second position in which the barrel extends downwardly from the frame.
摘要:
A pallet for conveying pieces or components in assembly lines. The pallet includes a base structure, a rotatable platform above the base structure, a pair of vertical uprights, a pair of vertical columns respectively supported within said vertical uprights and an arch-shaped cross-member selectively engagable with the vertical columns. The arch cross-member selectively connected to an assembly component whereby the component may selectively be positioned at different heights and angular orientations to the platform and base for case of access to the component by a user.

Embodiments generally relate to hinge mechanisms. Many of the hinge mechanism embodiments may be used in foldable furniture. The foldable furniture may be a foldable seat or table. The hinge mechanism may include a central cylinder with a body defining a hinge axis. The central cylinder may have rotate channel(s) transverse to the hinge axis and locking channels extending axially from the rotate channel(s). Collar(s) may couple with the central cylinder and may include pin(s) that protrude inwardly into the rotate channel(s) and locking channel(s) of the central cylinder. In some embodiments, an intermediate cylinder may be disposed between the central cylinder and the collar(s). The intermediate cylinder may have slots corresponding to the rotate channel(s) of the central cylinder. When pin(s) and locking channel(s) are aligned, the central lock cylinder may move axially to lock the collars in a desired angular position (e.g., a deployed or folded configuration).

An extendable sawhorse includes a main body having a platform and a plurality of receiving members depending therefrom. The sawhorse is adjustable between an extended arrangement and a condensed arrangement. A plurality of extension members are interchangeably coupled to each of the receiving members in the extended arrangement. The extendable sawhorse further includes a plurality of feet having a first end and a second end. The first end of the feet is coupled to the extension members in the extended arrangement and the second end of the feet is coupled to legs in the condensed arrangement.
摘要:
An apparatus for use in detecting at least one object hidden behind a wall or surface such as a metal fastener finder or a metal stud finder including a handle and a flexible member. The handle has a proximal end and a distal end and has a size and shape for being grasped by a hand of a user. The flexible member extends from the distal end of the handle, is movable or bendable independently of the handle, and includes multiple magnetic elements that are spaced apart from each other such that when a magnetic element is attracted to at least one hidden object, the flexible member bends to accommodate magnetic attraction between the at least one magnetic element and the at least one hidden object.

A portable and foldable lift can be attached to a surface such as a tailgate of a truck. The lift can be slid off the gate and used to lift heavy objects from the ground to the bed of the truck. The portable and foldable lift is returned in a folded position to the tailgate for easy storage. The portable and foldable lift can also be attached to a work bench, either on top or underneath, and can be folded up and stored out of the way.
