A safety switch includes a switch member and a push rod is pivotably connected to an inside of the switch member. A biasing member pushes the push rod toward a stop rod extending from the inside of the switch member. A bi-metallic contact plate has a first end fixed to one of two terminals and a contact portion splits from the contact plate. A first contact point is connected to an underside of the contact portion and a second contact point is connected to the other terminal. A free end of the c...

A safety light is mounted retractably in a handlebar of a bicycle and has a housing, a retaining clamp, a sleeve, a lamp assembly and a spring. The retaining clamp is mounted in the housing. The sleeve is mounted around the housing. The lamp assembly is mounted slidably in and selectively protrudes from the housing and comprises a lamp housing, a retaining post and a light assembly. The lamp housing is mounted slidably in the housing and has an inner end, an outer end and at least one lamp hole....

A safety grater having a parallelepipedal base body, an attachment that slides back and forth along guide rails by slide bars and that has a cylinder, into which items to be grated and sliced and a plunger are introduced and having at least one grating insert that can be fitted into the base body. The base body has elements that prevent the use of the grating and slicing insert without the attachment.

A safety device for a needle is provided. The device includes a spring biased sheath which acts to cover the needle before and after use. The safety device also includes a spring biased lock which is operable to lock the sheath in a safe position unless the biasing force of the lock is countered by a user.

A switch includes a push rod which extends from an underside of a switch member and the push rod selectively pivots an action member in "ON" and "OFF" positions. A bi-metallic contact plate has a first end fixed to one of two terminals and a contact portion splits from the contact plate. A first contact point is connected to an underside of the contact portion so as to contact a second contact point on the other terminal when in "ON" position. A free end of the contact portion is connected with ...

A safety visor is produced by etching of metal and a grid that defines a large number of light-permeating holes. The safety visor has at least two zones where the holes are of different areas and/or configuration. An upper central zone has greater light transmission than the remaining zones of the safety visor. The C--C spacing for the hole is constant in both the vertical and lateral directions regardless of in which region of the safety visor the holes are located. In one preferred embodiment,...

A buoyant boom having: an elongate band extending across a water surface; floats rotatably mounted to the band with rotary bearings between each float and the band; and anchors securing the band at its ends or middle portion to a support, such as a river bed or a river bank structure for example.

A safety syringe is disclosed. A plurality of axial slits are formed in the outer wall of the unidirectional buckling chamber of the seat. An inner wall of the unidirectional buckling chamber has a second unidirectional buckling lip. A buckling head at a front end of the rod head of the push rod is installed with a unidirectional buckling lip; the third unidirectional buckling lip is installed with a plurality of slits so that the third unidirectional buckling lip is elastic. Thereby, by the axi...

Safety battery (10) includes cathode (21) and attached cover (15) that enclose anode (41). Cover (15) includes via (16) for providing access to anode (41). Anode (41) is protected by penetrable insulation medium (48). Battery (10) is used to power illuminated jewelry (60) for lip, tongue, or ear without danger of shock or burn to user, even if accidentally swallowed

As from a conventional semi-hinge fixed to the frame, a complementary door fixing semi-hinge having, emerging perpendicularly from its base plate (1), a slide (3) destined to be housed in a blind hole on the door edge, a slide which is closed by its free end by means of a lid (12) and having a pair of opposite longitudinal guides (4), in which respective sets of balls have been fitted for the sliding of a runner (8), provided with complementary guides (4') for the mentioned set of balls and whic...
