A safety handlebar is described in which telescopic handgrips are provided at the two opposing outer ends of the tubular frame of the handlebar. In each embodiment described, a shaft and an outer cover are locked together for telescopic movement on each tubular outer end of the handlebar frame. A bias member in the form of a coil spring biases the grip portion outward away from the tubular ends of the frame. A dampening mechanism is provided to retard the return of the grips to their original po...

A hypodermic syringe provides a simple mechanism for manually retracting its needle into the syringe after injection has been completed. The syringe preferably has an elastomeric barrel to exert a radial bias to seal on a retractable needle carrier and the plunger. Attachment components on the plunger and needle carrier engage such that withdrawal of the plunger releases the needle carrier for withdrawal into the syringe barrel.

A safety needle assembly has a hub and a needle cannula that projects distally from the hub. A shield is mounted on the needle cannula and can move from a proximal position adjacent the hub and a distal position for shielding the tip of the needle cannula. A fin projects from the hub to facilitate digital manipulation of the needle assembly. A proximal arm is hinged to the hub and a distal arm is hinged to both the proximal arm and the shield. The proximal arm is releasably engaged with the fin ...

A safety system that is configured to enhance the ability of individuals to identify points of egress in the case of actual fires or emergency situations. The safety system may include a power source, memory, a central processing unit (CPU), sensor(s), audible indicator(s), light source(s), switch(es), camera(s), a transceiver, a microphone, impact tool(s), and aromatic element(s). The power source may be any suitable AC or DC power source. The memory, CPU, audible indicator(s), light source(s),...

The present specification protective headgear including a unitary shell (1) having a bell shape with a non-uniform thickness, the shell being of sufficient size to enclose at least an upper part of the wearer's skull, the shell having an upper crown portion (6) with a central crown area (2) and a surrounding outer crown area (3), the shell further including a depending circumferential wall which has an upper wall area (4) adjacent to the outer crown area (2) and a lower wall area (5), the lower ...

An elastic visor for detachable mounting on headwear is of sheet neoprene having a reinforcing layer of nylon, with a crown aperture that is stretched around, and grips the surface of a headwear to which it is mounted. The neoprene, of about five millimeter thickness, serves to grip the surface of the headwear. The flexible material of the visor permits the peak to deflect under the application of undue force. Ear-protective side flaps and an extended protective neck-flap portion can be incorpor...

A safety device (23) for a fluid hose (14) having at one end one part (19) of a separable connector (18) by means of which the hose (14) may be connected to another pipe (21) carrying the other part (20) of the connector, the connector parts separating when the connector (18) is subjected to a tensile load. The device (23) includes an elongate tether (24) having one end attached to the hose (14) at or adjacent the one connector part (19) and its other end attached to the pipe (21) at or adjacent...

In a method for a safety valve plus such a safety valve, the safety valve has the form of a valve body axially displaceable in a cavity with an inlet on either side of which are arranged outlets, whereby liquid and/or gas flow takes place from the inlet and past the valve body via a flow path to the outlets. On the valve body side, the flow path is provided with a structure that raises the friction in relation to the liquid and/or gas flow between the inlet and outlets.

A safety fencing system is provided which includes a plurality of two-part poles. These poles have a flat edge and a curved edge providing a substantially "D" shape. In the preferred embodiment each flat edge includes a substantially concave portion and a substantially convex portion. These contours nest together when two flat edges are placed adjacent to one another, leaving a curved or round external shape. The nested contours and the flat edges receive a pliable material. These contours assis...

The present invention is a safety jack having a propping mechanism comprised of a prop attached parallel to and jointly movable with the lifting arm, a storage well for receiving the prop in a retracted position, and a pin engagable with the prop to bias the prop and the body of the jack to prevent untimely lifting arm retraction.
