Description

Title Hinge Device Field of the invention This invention relates generally to hinge devices and in particular to a hinge device which is also able to provide a reliable electrical connection between a fixed metal part and a rova tl e metal part hingedly coanectes by means sais ninge device.

Background to the invention It is sometimes @ requirement, for exemple in meta cabinets housing electrical equipment, for a fixed metal part such as the cabinet housing and a movable ,metal part such as the door hinges to the cabinet to be electrically interconnected. Typically, this electrical interconnection is currently achieved externally to the hinge, usually by means of a length of flexible electrical cable or braid welded or soldered between the two parts.

It is an object of the present invention to provide a hinge device capable not only of serving as a mechanical hinge between fixed and moving parts but at the same time also serving as a means of establishing a reliable electrical interconnnection between the two parts.

The invention According to the invention, there is provided a hinge device comprising a cup-shaped female member and a male member having a step formed between portions of lesser and greater diameter, at least the lesser diameter portion being of electrically conductive material, a bush seating into the open end of the female member to define both a thrust bearing for the greater diameter portion of the male member and a rotational bearing for the lesser diameter portion of the male member, said iesser diameter portion being received into the cup with both all round clearance and clearance at the bottom of the cup when the two parts of the hinge device are fitted together, and a spring contact secured within and electrically connecte te the cup and for bearing against the wall of the lesse diameter portion of the male member to maintain a reliable electrical connection therewith during relative rotation of the male and female parts.

A preferred spring contact is a U-shaped contac; eler.ent having its cross piece seoured to the base u f the cup p afl d its upstanding limbs spring set to lean towards one another, thereby to be sprung away from one another wnen the lesser diameter portion of the male member is received into the cup.

The lesser diameter portion of the male member, which constitutes its contact portion, is preferably formed as a separate element removable from the greater diameter portion, and it may thus be made of a different material.

In an embodiment, the main or major diameter portion of the male member, and likewise the cup-shaped female member, are made of steel, the lesser diameter contact portion of the male member is made of brass, and the spring contact is made of sprung steel with plated contact regions.

The said plated regions of the spring contact are preferably constituted by inward projections formed at the free ends of the 1 libs of the U-shaped contact element and which, when the two parts of the hinge are fitted together, engage into a peripheral groove formed in the wall of the contact portion of the male member.

The hinge device in accordance with the invention is also able to provide an electrical interconnection between an additional pair of contacts, being contacts respectively internally wired within the two parts of the hie device for connection with external cables. For thie punpos the lesser diameter portion of the ai meander is formed with two contact portions longitudinally separated by dn electrically insulating spacer, and the cup is provided with a second U-shaped spring contact element eiectrical insulated from. the first and having, longer limns, whereby one spring contact engages one contact portion of the male member and the second spring contact engages the other contact portion of the male member when the to parts of the hinge are fitted together.

It will thus be appreciated that, in a mcAification, the hinge device may be used electrically solely for the purpose of providing a reliable interconnection between external cables, the above-described additional contacts of the male and female members being the only contacts incorporated.

Thus, while generally the main portion of the male member and the cup-shaped female member will be made of steel or equivalent electrically conductive material for the purpose of establishing an electrical connection, usually an earth connection, between fixed and moving metal parts such as the housing and the door of a metal cabinet, the said main portion of the male member and the cup-shaped female member could possibly be made of plastics or other non-electrically conductive material when the hinge device is to be used electrically only for the purpose of interconnecting external cables. Nevertheless, the hinge device will continue, of course, to provide a mechanical hinge connection between fixed and moving parts, even though it is not these parts which are being electrically interconnected.

The two members of the hinge may slither be welded respective fixed and moving parts to be hinged together, or apertured to receive securing screws for this purpose.

Especially in the case of a door, for example, the female newber wI be secured to tht? fixed support such as cabinet housing, with the cup upright, and the male m.e;.-er fixed to the door, so that the male member seats downwardly into the cup. Normally, it will be possible for the door readily to be lifted out from or dropped oack into its hinged condition.

Description of embodiments Two embodiments of hinge device in accordance with tne invention are now described by way of example with reference to the accompanying drawings, in which: Figure 1A shows one embodiment with the two hinge members in separated condition; Figure 1B shows the hinge members in engaged condition; Figure 1C shows the two hinge members, when separated, in perspective; Figure 2 shows a second embodiment in like manner to Figure 1A.

Referring to Figure 1, the illustrated hinge device comprises a cup-shaped female member 10 of stainless steel, welded 4o a housing or enclosure 12, and a male member 14 of stepped cylindrical form having a major orion 1f, of stainless steel, welded t a dcc 18.

indicated in Figure 1C, the two parts c t ninge v;cr could alternatively be fixed to the enclosure and door by securing screws 21.

The male member 14 also inclodes a lesser diameter contac portion 20 in the form of a detachable stud of tírass.

A lipped bush 22 of nylon or equivalent material seats into the open top of the cylindrical cup 10 to define both a thrust bearing for the bottom annular end face of the major portion 16 of the male member 14 and a rotational bearing for the contact portion 20 of lesser diameter, which is received into the cup with all round clearance, as shown in Figure 1B.

Mechanically and electrically fixed to the base of the cup 10 by means of an eyelet fixing 24 is a U-shaped spring contact element 26 of stainless steel having plated contact portions 28. The contact portions 28 are defined by inward projections formed at the upper ends of the limbs of the U-shaped contact element 26. These limbs are spring set to lean towards one another and be slightly sprung apart when the contact portion 20 of the male member 14 is received into the cup 10 between said limbs, whereby the contact portions 28 are received into a peripheral groove 30 in the wall of the contact portion of the male member, to establish a reliable electrical interconnection therewith, which is maintained when, during hinging, the male and female members of the hinge device are relatively rotated.

Thus, when the hinge device is provided between the enclosure and door of a metal cabinet, a reliable interconnection, such as an earth connection, is est3blished between the enclosure and the door within the hinge itself, arid any requirment for flexible interconnecting braid or tE lie is is pens end wi tr..

Figure 2 shows a second embodiment which has all the features of the embodiment of figure 1, but also provides for a second electrical interconnection through the hinge between external cables 4û. In general, the same reference numerals are employed in Figure 2 as in Figure 1.

The additional electrical interconnection is effected by means of a split contact portion on the male member defining peripherally grooved contacts 42, 44 separated by insulating spacers 46, and a second U-shaped contact element 48 with contact portions 50 fixed within the cup, electrically insulated from the first U-shaped contact element 26 and disposed in a plane at right angles to the plane of the first contact element. The lengths of the limbs of the two contact elements 26 and 48 are different, so that when the hinge device is assembled, one contact element 26 engages one contact 42 of the male member and the second contact element 48 engages the other contact 44 of the male member.

The additional contacts, say 44 and 48, are internally wired within the hinge to electrically interconnect with the external cables 40.

Various modifications of the above-described and illustrated embodiments are possible within the scope of the invention hereinbefore defined.
