Embodiment Construction

[0023] First will be based on figure 1 Both the embodiments of the electrostatic discharge chair cover with the grounding plate, figure 1 Shown is an antistatic chair cover (12), an elastic conductive grounding ring (14) and a grounding piece (16). The antistatic chair cover (12) is preferably a detachable electrostatic discharge chair cover. Suitable for use with accessories on a conventional swivel chair (17) that swivels around a swivel rod (34).

[0024] The detachable chair cover (12) is made of antistatic material. It is used to cover the back (18) and seat (20) of the chair. A conductive or anti-static strap (22) is used to maintain contact between the backrest and seat to discharge static electricity from the backrest to the seat of the chair.

[0025] The elastic conductive grounding ring (14) includes a connector (24) and a pair of helical springs (26), such as Figure 2A shown. Preferably a buckle is used as connection ( 24 ). A helical spring is attached to ...

Abstract

Electrostatic discharge chair with a grounding disc suitable to be used on a swivel chair are described. The accessories comprise a static dissipative chair cover (12), flexible conductive ground loop (14) and grounding means (16). The flexible conductive ground loop (14) have an attaching means (24) attached with two flexible coiled springs, the first spring having an open end (26a) and the second spring having an open tapered (26b) end. The flexible conductive ground loop (14) is attached to chair cover (12) and wrapped around swivel post (34) by screwing one end of the spring into the other to provide a ground path from chair cover to swivel post. The grounding means (16) is attached to swivel post and in contact with ground to provide a ground path from swivel post to ground.

Description

technical field [0001] The present invention relates generally to static control devices and, more particularly, to a grounding device for discharging static charge that builds up on a chair. Background technique [0002] Static electricity is a type of electrical charge that is produced primarily by frictional motion that causes electrons to become unbalanced at rest. The magnitude of static electricity is related to factors such as material type, separation speed, contact pressure, and relative humidity of the environment. The instantaneous discharge of static electricity is called electrostatic discharge. Some electronic devices cannot withstand a spark discharge that will permanently damage the device. The more transistors that are packed into an electronic device, the more vulnerable that device is to damage from static sparks. [0003] Protective measures are required in the production and operation of electrostatic discharge sensitive components to reduce or hopefu...
