A gate holding device for holding an agricultural gate (1) during installation is disclosed. The device (7, 57, 207) takes the form of an elongate attachment member defining a first axis and having a first hinge member (20, 70, 270) connected thereto adjacent a lower end of said attachment member, an elongate foot piece (8, 58, 208) defining a second axis substantially perpendicular to the first axis and having a second hinge member (21, 71, 121) connected to the foot piece intermediate the ends thereof and perpendicular to the second axis, the first and second hinge members being connected together to permit rotation of the foot piece relative to said attachment member between an initial position where the foot piece is substantially parallel to the gate and a final position in which the foot piece is substantially perpendicular to the gate. Preferably a pair of such devices is used. A method is also disclosed.

A stand for a laser projection device is provided. The stand includes a mounting structure that couples to the laser projection device. In one embodiment the stand includes three legs that are coupled together at a junction, and a central column extends downward from the junction and the mounting structure is coupled to the mounting structure, thereby permitting the laser projection device to emit light towards a ground.

A supporting apparatus and a display device are disclosed. The supporting apparatus is configured for supporting an external apparatus, and includes: a bracket supported on a supporting surface and having a waist-shaped hole; and a rotating member with one end passing through the waist-shaped hole and the other end connected to the external apparatus. Under action of an external force, the rotating member is slidable and rotatable relative to the bracket in the waist-shaped hole. When the external force disappears, the rotating member remains stationary relative to the bracket.

A display mounting device includes a supporting pillar and a supporting pillar fixture. A display is mounted on the supporting pillar. The supporting pillar fixture is installed on a floor surface and coupled with the supporting pillar. In an extending direction of the supporting pillar, the display is detachably attached to a first end of the supporting pillar, and the supporting pillar fixture is coupled with a second end of the supporting pillar opposite to the first end in a rotatable manner. The supporting pillar fixture includes a rotation support that supports the supporting pillar in a rotatable manner. The rotation support allows for rotation of the supporting pillar within a range of angles between a first state where the extending direction of the supporting pillar is parallel to the floor surface and a second state where the extending direction of the supporting pillar is perpendicular to the floor surface.

A self-standing tablet device case covering the top, bottom, left, and right edges of a device comprising of a collapsible leg base centrally affixed on the back side of the tablet device case, whereby the collapsible base comprises of a folding base and adjustable legs that are hingedly connected to the folding base and fixedly connected at equal distances from the left and right sides of the self-standing tablet case and the non-exposed section of each adjustable leg resides within a housing that is fixedly connected to the back of the self-standing tablet case.

A collapsible support structure for a removable electronic device. The electronic device having a touch screen configured for a user to access at least one predetermined construction document and/or application is removably connected to the support structure. The electronic device may be retained in a housing configured to be water resistant and/or impact resistant. The support structure may have a locking mechanism configured for an authorized user to gain access to remove the electronic device from the support structure, thereby, preventing an unauthorized user from gaining access for removal of the electronic device from the support structure. The support structure is configured to be foldable in a closed orientation during storage. The support stand may have a plurality of casters connected to a base. The base has a removable battery connected to a charging system with an integrated uninterruptable power supply.

A wall mount for a display apparatus comprises: a mount holder including a first fixing portion coupleable to a wall surface and a second fixing portion coupleable to the first fixing part; and a body including a coupling bracket coupleable to the display apparatus and a mounting hole insertable into and coupleable to a gap between the first fixing portion and the second fixing portion of the mount holder while the second fixing portion is coupled to the first fixing portion, where the second fixing portion is rotatable in a first direction and a second direction opposite the first direction so that a width of the gap is adjusted according to the second fixing portion being rotated in the first direction and the second direction.

A bracket includes a fixing seat, an adapter seat, a first clamping block, a second clamping block, a first clamping piece, a second clamping piece, a main screw and a position-limiting element. The fixing seat includes a first protrusion post. The adapter seat includes a second protrusion post. The first clamping block includes a first through-hole and a first pivot hole. The second clamping block including a first tapped hole and a second pivot hole. The first clamping piece includes a first clamping part and a first pivotal shaft. The first pivotal shaft is inserted into the first pivot hole. The second clamping piece includes a second clamping part and a second pivotal shaft. The second pivotal shaft is inserted into the second pivot hole. The main screw is penetrated through the first through-hole and then tightened into the second tapped hole.

The disclosed invertible structures rely on combinations of translational movements to effect inversion. An exemplary invertible structure includes a track operable to be slidably coupled to a connector element of a longitudinal structure. In an embodiment, the connector element may include at least two connectors at least partially disposed in a slot defined in the track, which may have a plurality of translational axes for translational movements of the connectors of the longitudinal structure that would effect the inversion of the longitudinal structure.
