Abstract

A hinging device for a casing of a portable computer has an axle (30) fitted into an inner tube (10) which is further fitted into an outer tube (20). A first engaging end (31) of the axle (30) protrudes from the inner tube (10) and is connected to a cover portion (34) of a casing, while the outer tube (20) has a second engaging end (21) connected to a body portion (22) of the casing, such that when the axle (30) is operably pivoted in the outer tube (20), friction therebetween is able to anchor the cover portion (34) in a desired position relative to the body portion (22). <IMAGE>

Description

TITLE: HINGING DEVICE FOR CASING This invention relates to a hinging device for a casing, especially a casing of the type employed in a portable computer or the like.
A conventional hinging device as shown in Fig. 5 of the drawings is comprised of an axle 41 pivotally received by a holding frame 43, and an elastomeric gasket 42 disposed therebetween for providing a compressive friction in the engagement of the axle 41 and the holding frame 43. However, after long term use, the elastomeric gasket 42 will lose its elasticity and cause a malfunction of the hinging device.
Accordingly, the present invention is that of a hinging device for a casing comprising an axle fit into an inner tube which is further fit into an outer tube.
The axle includes a rod portion, a flange portion, and a first engaging portion. The outer tube includes an open end and a second engaging portion. The inner tube and the axle are received in the outer tube via the open end thereof, with the first engaging portion protruding from the outer tube and the rod portion frictionally and pivotally received in the inner tube, and with the flange portion against an outer end of the inner tube. The first engaging end of the axle which protrudes from the outer tube is connected to a cover portion of the casing, while the outer tube has a second engaging end connected to a body portion of the casing, such that when the axle is operably pivoted in the outer tube, friction therebetween is able to anchor the cover portion in a desired position relative to the body portion.
It is an object of the present invention to provide a hinging device for a casing which provides long life effect.
Fig. 1 is an exploded view of a hinging device in accordance with the present invention; Fig. 2 is a perspective view of the hinging device of the present invention connected to a portion of a casing; Fig. 3 is a fragmentary cross-sectional view taken along line 3-3 of Fig. 2; Fig. 4 is a schematic view showing the hinging device arranged in a casing; and Fig. 5 shows a conventional hinging device.
Referring to Figs. 1 to 4, a hinging device for anchoring a pivotal cover 34 in a position relative to a body portion 22 has a pair of hinging means each of which comprises an axle 30, an inner tube 10, and an outer tube 20. The axle 30 comprises a rod portion 37, a flange portion 33, and a first engaging portion 31 securely attached to the pivotal cover 34. The outer tube 20 comprises an open end 25 and a second engaging portion 21 securely attached to the body portion 22.
The inner tube 10 and the axle 30 together are received in the outer tube 20 via the open end 25 with the rod portion 37 frictionally yet pivotally received in the inner tube 10 and with the flange portion 33 against an outer end of the inner tube 10. Friction between an inner periphery of the inner tube 10 and an outer pe riphery of the rod portion 37 and between an inner periphery of the outer tube 20 and the flange portion 33 enables the pivotal cover 34 to be anchored in a desired position relative to the body portion 22.
As shown in Fig. 4, a pair of hinging means is disposed on two sides of the casing. Nevertheless, the number of the hinging means can be varied. The hinging means can be used in different types of casings, and the number thereof depends on the type of casing.
The inner tube 10 is made of polymide material to provide long life effect, because the inner periphery and the outer periphery thereof experiences relatively high friction when manually anchored the axle 30 with respect to the outer tube 20.
The first engaging portion 31 of the axle 30 is fit to a lug 35 of the cover portion 34 and the second engaging portion 21 of the outer tube 20 is fit to a second lug portion 23 of the body portion 22. The first engaging portion 31 of the axle 30 is formed with a first groove 32 for receiving a first C-ring 36 to further secure the axle 30 to the cover portion 34.
Also, the second engaging portion 21 of the outer tube 20 is formed with a second groove 27 for receiving a second C-ring 24 to further secure the outer tube 20 to the body portion 22. However, the engaging portions 31 and 21 are not limited to those shown in Fig. 1. The engaging portions 31 and 21 are easily changed to compliment different casings.

Claims (3)

I claim:
1. A hinging device for anchoring a pivotal cover in a position relative to a body portion including at least a hinging means comprising: an axle, an inner tube, and an outer tube; said axle comprising a rod portion, a flange portion, and a first engaging portion securely attached to said pivotal cover; said outer tube comprising an open end and a second engaging portion securely attached to said body portion; said inner tube and said axle being received in said outer tube via said open end with said rod portion frictionally and pivotally received in said inner tube and with said flange portion against an outer end of said inner tube; whereby friction between an inner periphery of said inner tube and an outer periphery of said rod portion and between an inner periphery of said outer tube and said flange portion enables said pivotal cover to be anchored in a desired position relative to said body portion.
2. A hinging device for casing as claimed in claim 1, wherein said inner tube is made of polymide material.
3. A hinging device for casing substantially as hereinbefore described with reference to and as shown in the accompanying drawing.
