A safety switch includes an activation key housed in a casing, a pair of contact-holding elements, and a triad of electric terminals. The contact-holding elements oscillate between a passive position and an active position, the positions being imposed by a corresponding position of the activation key. The contact-holding elements are mutually electrically connected through conductive elements that, when operation of the switch takes place in a condition of failure, can move with respect to one a...

A safety support comprising a plate with ribs and a U-shaped upper part with two lateral branches and an upper base zone. The two lateral branches each comprise an articulation zone including pivoting axles extending parallel to the plane defined by the upper part and two superposed connecting zones, which are mutually linked by an assembly part, each having a bore for its respective pivoting axle. Moreover, each articulation zone comprises at least three pivoting axles, the connecting zones hav...

A lighting device for a safety helmet or the like used for recreational and industrial purposes wherein a plurality of blinking LEDs are disposed on the outer surface of the helmet. The only circuitry needed is a 3 volt battery, an On-Off Switch and wiring for interconnecting the LEDs

A pull down storage shelf assembly for a standard wall cabinet to access items on the upper storage shelf is described. The shelf assembly has two arms on each side attached to an upper support member on one end and a lower support member on the other end. The position of the two side arms with respect to the upper and lower support member allows the shelf to hold in place when in the up position. A handle is secured to the front and bottom of the pull down shelf. When the handle is pulled forwa...

A safety goggles comprises a frame including an attachment member projected above the top center and a slanted coupling surface on the top of the attachment member; a lens fitted in the frame; a protector guide; a shade including a frame, an opening defined by the frame, a flange extended inward from the frame, studs on the frame of the shade, projections on either inner side of the flange of the shade, an engagement member projected above the top center of the flange of the shade, and an inclin...

A safety syringe includes a barrel, a needle-carrier and a plunger. The plunger and the needle-carrier each have a coupling system which connects them by a simple axial push of the plunger. The distal part of the barrel has an internal annular stop. The central part of the needle-carrier has an external diameter corresponding to the internal diameter of the annular stop while the proximal extremity of this part of the needle-carrier has a diameter corresponding to the internal diameter of the di...

A safety harness having a chest strap received over a user's shoulders, a crotch strap received between a user's legs and selectively attachable to the chest strap, and a back panel received against a user's back, the back panel being interposed between the crotch strap and chest strap. The back panel is substantially the width of the user's shoulders and the height of the user's torso to evenly disperse and dissipate forces from sudden movements acted upon a user when the harness is secured to ...

A safety valve has a valve body, a piston contained in the valve body, a soluble alloy filled between said piston and said valve body, and a spring inserted between the piston and the valve body. The piston includes a path connecting both ends thereof, and has a first gas pressure receiving surface and a second gas pressure receiving surface at both ends. The first and second gas pressure receiving surfaces have the same area; the piston works as a balanced piston where the gas pressure in the f...

A safety syringe ensuring stable and airtight connection of a hub to a barrel of the syringe is provided. A rear portion of the hub is tightly fitted in a neck portion at a front end of the barrel, such that the hub is prevented from moving out of the barrel via the neck portion. A first airtight contact line is formed at joint of two shoulder portions separately formed on the hub and the neck portion, and a second airtight contact line is formed at a position within a contact surface between th...

A safety fishhook which substantially prevents skin punctures is formed from a wire and includes a first end adapted for attachment to a line, a shank adjacent to the first end, and a curved bend extending from the shank to a free end, the curved bend defining partially enclosing a planar area, and the free end terminating within the area and being oriented at a safe angle with respect to a line bounding the curved bend and the first end.
