Provided are a wheel-frame locking assembly of a foldable vehicle, and a foldable vehicle using said wheel-frame locking assembly. The wheel-frame locking assembly comprises a fork (1), said fork being provided with a first pin hole; a wheel frame; the end of the connection between the wheel frame (1) and the fork is provided with a sleeve (2); By means of the sleeve (2), the wheel frame is rotatably sleeved on the fork (1); the sleeve (2) is provided with a second pin hole fitting the first pin hole, and when the wheel frame is opened to a use state, the second pin hole aligns with the first pin hole, a positioning member arranged on the fork (1) and preventing the wheel frame from falling off the fork (1); a lock pin (6) fitted with the first pin hole and the second pin hole and used for locking and unlocking the wheel frame to and from the fork (1). The wheel frame locking assembly enables a foldable vehicle to be further folded, and the wheel frame rotates around the fork (1), then the folding of the wheel frame itself is accomplished, thus the space occupied by the foldable vehicle after folding is further reduced effectively improving the portability of the foldable vehicle.

A system for securing a first container to a second container comprises an upper locking portion and a lower locking portion. A first protrusion of the upper locking portion abuts the second container and restricts movement of the second container in the locked position. A surface of a second body of the lower locking portion is configured to receive a force and to cause the lower locking portion to rotate about a second pivot to an unlocked position. The rotation of the lower locking portion to the unlocked position causes a second protrusion of the upper locking portion to abut a first body of the upper locking portion and cause the upper locking portion to rotate to an unlocked position. The rotation of the upper locking portion to the unlocked position causes the first protrusion to disengage from the second container.

The present invention involves a device for holding and transporting a gas cylinder. The device, a hand truck, has an arm portion having a lip portion mounted thereon. The device also has at least one stabilizing peg mounted to the lip portion with two wheels mounted to the lip portion. The at least one stabilizing peg is sized and configured to engage the stabilizing ring of the gas cylinder placed on the lip portion. Optionally, a hook may be attached to the arm portion such that the hook may engage the gas cylinder. The arm portion may further comprise a handle portion pivotable between a raised position and a collapsed position. The handle portion is lockable in the raised position and the lowered position. The arm portion further comprises a cradle portion sized and configured to engage and stabilize the gas cylinder. The gas cylinder, having a stabilizing ring, may be tilted forward, and the hand truck may then be positioned to engage the cylinder. The gas cylinder may then be tilted back so that the stabilizing ring rests on the lip portion of the hand truck and is engaged by the at least one stabilizing peg. This allows for the tilting of the hand truck and cylinder backward so that the hand truck and cylinder may be wheeled freely.

The present invention relates to a manually operable carriage and working attachments that may be employed with the carriage. The attachments may include a plow, a logging clamp, or other implements.

An improved apparatus for hauling supplies, including, but not limited to, supplies held in buckets or other containers. The disclosed apparatus also provides improvements for supply storage. An embodiment provides removably attached racks, the racks being adapted for storing removable containers when attached, and is configured for storing the racks thereupon when detached. In an optional aspect, a removably attached suspension member provides for additional supply storage, and the suspension member may also be stored upon the apparatus when detached. Supplies may be stored upon the apparatus while it is stationary, and may also be hauled from place to place using the apparatus.

An example cart inventory system and associated methods are described. The example cart inventory system includes a cart and a detection system. The cart includes a frame, and a shelf movably mounted to the frame and configured to be positioned between an extended position and a folded position. A top surface and a rear surface of the shelf include first and second identifiers, respectively. The detection system is configured to detect the first identifier when the shelf is in the extended position and detect the second identifier when the shelf is positioned in the folded position. In the extended position, the top surface is oriented upwards relative to horizontal and the rear surface is disposed against the frame. In the folded position, the rear surface is oriented upwards relative to horizontal.

A collapsing blade comprising an upper and lower handle section joined at the rear by pivotal means; a set of arms pivoted upon the lower handle section, a rear blade pivoted on the upper handle section by means of an embracing body; a front blade comprising a hollow portion and an edged portion pivotally attached to said arms and rear blade; wherein by angular rotation of handle sections the blade assembly is arranged from collapsed to extended configurations.

A tile laying device has a main frame supported on wheels for rolling movement along a ground surface. A pendulum frame is supported on the main frame to be freely suspended from the main frame while being adjustable in height relative to the ground surface by tilting the main frame about the axis of the wheels. Suction cups on the pendulum frame allow a tile to be coupled to the tiles using vacuum pressure from a vacuum pump on the main frame. The suction cups can be shifted laterally in a direction of the pendulum axis relative to the main frame to assist in aligning a tile on the pendulum frame with a desired placement location for the tile.
