A folding table and chair device has a chair assembly and a table assembly. The chair assembly has a supporting bracket, a seat mounted securely on a top of the supporting bracket, a backrest mounted pivotally on a rear end of the seat, and a footrest mounted pivotally on a front end of the seat and being capable of pivoting forward to a horizontal position. The table assembly is mounted in front of the chair assembly and has a wall board mounted in front of the chair assembly, and a folding table mounted pivotally on the rear of the wall board and being capable of pivoting downward to a horizontal position. The folding table and chair device allows a user to lie completely down thereon.

Folding table and chair device

A rotatable vehicle seat frame assembly has a main frame, at least one first seat frame, at least one second seat frame, and at least one elevatable desk. Each seat frame has a bottom sliding mechanism, a top sliding mechanism, and an angle-adjusting mechanism. The second seat frame further has a leg rest assembly. The bottom sliding mechanisms, the top sliding mechanisms, the angle-adjusting mechanisms, and the leg rest assembly enable the seat frame to be rotated into a flattened status in a limited inner space of a vehicle, enable the seat frame to be transformed between a passenger-mode and a cargo-mode, and enable the seat frame to be used as a bed during a long trip. When in the passenger-mode, the position of the seat bracket and the angle of the back support bracket may be adjusted to facilitate convenience, and to provide more use modes in a limited inner space with the elevatable desk.

Rotatable vehicle seat frame assembly

A foldable leg rest has a seat, a folding frame and a drive mechanism. The folding frame is pivotally connected to the seat. The drive mechanism includes a first actuator and a second actuator. The first actuator has a front end and a rear end. The front end of the first actuator is pivotally connected to the folding frame. The second actuator has a front end and a rear end. The rear end of the second actuator is pivotally connected to the seat. The front end of the second actuator is secured to the rear end of the first actuator. The first actuator and the second actuator are actuated to pivot the folding frame to a horizontal plane in which the seat lies.

Foldable leg rest

A foldable leg rest has a seat, a first folding frame and a first stage drive mechanism. The first folding frame is pivotally connected to the seat. The first stage drive mechanism includes two angle adjusters, two first stage DC motors and a drive rod. Each of the angle adjusters is disposed between one of opposite sides of the seat and one of opposite sides of the first folding frame. The first stage DC motors are respectively disposed on the sides of the seat. The drive rod is connected between the angle adjusters. In use, the first stage DC motors are actuated to drive the drive rod and the angle adjusters such that the first folding frame is pivoted relative to the seat.

A multi-functional table and chair device has a base, two opposite chair sets mounted on the base, and an adjustable table. Each chair set has at least one chair, and each chair has a supporting bracket, a seat, a backrest and a footrest. The adjustable table is mounted on the base between the chair sets and has a bottom bracket, an elevation mechanism and a table board. When the backrest of one chair is pivoted backward and the footrest is unfolded, the chair is changed into a deck chair. When the footrests of two opposite chairs of the chair sets are pivoted upward and unfolded to be horizontal and the adjustable table is raised to hold the footrests, the two opposite chairs and the adjustable table form a bed.

Multi-functional table and chair device

A foldable leg rest has a slide base, a first folding assembly, a second folding assembly, a first stage drive mechanism and a second stage drive mechanism. The slide base has a slide frame. The first folding assembly has a first frame pivotally connected to the slide frame. The second folding assembly has a second frame pivotally connected to the first frame. In use, the first stage drive mechanism is operated to drive the first frame to pivot relative to the slide frame and the second stage drive mechanism is operated to drive the second frame to pivot relative to the first frame. Therefore, the legs of a sitter can be stretched and placed on the folding assemblies so as to enhance comfort and minimize fatigue.

A lock structure. The lock structure includes a first element, a second element, a guiding element and a fixing pin. The first element has a guide hole and a first through hole located under the guide hole. The second element is deposed under the first element and has a second through hole that is co-axially aligned with the first through hole. The guiding element rotates and is movably disposed in the guide hole. The guiding element has a third through hole aligned with the first through hole. The fixing pin is inserted through the third through hole, guide hole, first through hole and second through hole and has a first retaining portion. The first retaining portion is formed on the lower portion of the fixing pin and located under the second element.

Lock structure and method for using thereof

A valve safety lockout device and a method for using such device to tamper-proof a control valve are disclosed. In the device, a hollow toroidal-shaped body that is divided into two equal halves circumferentially forms the body for the lockout device. A plastic molded-in hinge connects the two equal halves at one end, and a male latch member and a female latch member are each formed at an opposite end of the two halves such that once they are engaged together, the two halves cannot be detached without destroying the latch members and thus making it visible to an operator. The plastic hollow body of the lockout device can be suitably molded of a plastic material of high rigidity including a molded-in plastic hinge connecting the two halves together. The rigidity of the plastic material should be such that the lockout device cannot be compressed or squeezed in order to turn the control valve handle.

Valve safety lockout and method for using

The present disclosure is related to a combination lock with code thereof randomly variable, which is equipped with a pair of parallel rods disposed within an oblong casing; the upper actuation rod is provided with a number of spaced actuation claws with a corresponding number of dial wheels secured to the lower slide rod. Part of the dial wheels is exposed externally of the casing for easy dialing operation thereof. On each dial wheel there are disposed ten axial holes in accordance with consecutive digits 0-9, and a matching restraint wheel in securing engagement with each actuation claw is equipped with a pair of protrusion rods on the side facing each dial wheel which is in selective engagement with two holes of the dial wheel so to enable an operator to set new code by first making each restraint wheel disengaged from the dial wheel by way of the movement of the actuation claws secured on the actuation rod, and rotating the dial wheel to a new position and then making the restraint wheel engaged with the same again.
