Description
FIELD OF THE INVENTION
[0001] The present invention relates to a computer host casing and
particularly to a casing structure for portable computers that
provides fast assembly and disassembly.
BACKGROUND OF THE INVENTION
[0002] Conventional computer host generally has a rectangular
casing for resting on the desktop or on the floor. For moving the
computer, users have to hold the casing with two hands. As the
computer host is quite heavy, users have to squat to hold the
computer standing on the floor with two hands. Since the
conventional computer host casing does not have handle for
grasping, it is not convenient to move for transportation or
carrying.
[0003] Moreover, some users often have the computer host directly
standing on floor. The metal casing is easily rusted due to the
damp condition of the floor. The electronic elements in the
computer host also tend to adsorb moisture and may result in
malfunction. Some users try to pad the computer host with a wooden
board or the like. However the computer host and the padding wooden
board have to be removed when the floor is cleaned. And the
computer host has to be moved back to its original position after
the cleaning is finished. It is troublesome.
SUMMARY OF THE INVENTION
[0004] The primary object of the invention is to provide a computer
host casing that includes a first side board and a second side
board located respectively on a left side and a right side and four
connection members connecting four corners of the first and second
side boards. The two side boards are wedged with coupling elements
which are movable by fingers. The coupling elements may be latched
on the side walls of the computer host. The casing thus formed has
fewer elements and may be assembled quickly. It also may be carried
easily by hands for moving. The computer host also may be placed on
the floor without damping.
[0005] The foregoing, as well as additional objects, features and
advantages of the invention will be more readily apparent from the
following detailed description, which proceeds with reference to
the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] FIG. 1 is a perspective view of the present invention.
[0007] FIG. 2 is an exploded view of the present invention.
[0008] FIG. 3A is a fragmentary plane view of an embodiment of the
present invention.
[0009] FIG. 3B is a cross section taken on line 3B-3B in FIG.
3A.
[0010] FIG. 3C is a schematic view of the invention in an operating
condition according to FIG. 3B.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] Please refer to FIGS. 1 and 2, the computer host casing
according to the invention includes:
[0012] a first side board 10 located on a left side wall of a
computer host 1. The first side board 10 is substantially a square
plate with four sides each having a first arched edge 11 indented
inwards. Two neighboring first arched edges 11 form a first
extension plate 12 therebetween at an angle of 45.degree.. There is
a first elliptic and indented port 13 formed on the first extension
plate 12. The first indented port 13 has a first slot 131 inclined
at 45.degree.;
[0013] a second side board 20 located on a right side wall of the
computer host 1 that has the same shape and structure as the first
side board 10 to correspond to the first side board 10. It also has
four sides each having a second arched edge 21 indented inwards.
Two neighboring second arched edges 21 form a second extension
plate 22 therebwteen at an angle of 45.degree.. There is a second
elliptic and indented port 23 formed on the second extension plate
22. The second indented port 23 has a second slot 231 inclined at
45.degree.;
[0014] four. connection members 30 for connecting four corners of
the first and second side boards 10 and 20. Each connection member
has two sides bent to form respectively a wing plate 31 to become a
U-shaped plate. The wing plate 31 may be fastened to a side wall 2
of the computer host 1 through two fastening elements 32 (such as
rivets). The inner side of the connection member 30 is bent to
match the arched edges 11 and 21 of the first and second side
boards 10 and 20 to form a handle 33 between the two wing plates 31
for hand grasping (or pedestal for resting on the floor); and
[0015] eight coupling elements 40 (referring to FIG. 3A). Four of
them are movably mounted on the first indented ports 13 of the
first side board 10, and other four are movably mounted on the
second indented ports 23 of the second side board 20. Each coupling
element 40 includes a latch member 41 which has four struts 42 on
the rear wall thereof. Two of the struts 42 have respectively a
screw hole 421. The four struts 42 run though the first slot 131 of
the first indented port 13 (or the second slot 231 of the second
indented port 23). An elongated sliding member 43 is mounted on an
inner wall of the first side board 10 corresponding to the first
indented port 13 (or on the inner wall of the second side board 20
corresponding to the second indented port 23). It has one end
forming a coupling end with four apertures 431 formed thereon
corresponding to the four struts 42 of the latch member 41. Two of
the apertures 431 may be engaged respectively with a screw 432 to
couple with the screw hole 421 of the struts 42 to fasten the
sliding member 43 to the latch member 41 so that the latch member
41 can move the sliding member 43 concurrently upwards (or
downwards). The sliding member 43 has other end forming a carved
and arched groove 45 to become a movable end to provide an elastic
compression. The movable end has a bulged latch spot 44 on an inner
side to engage with a latch trough 3 formed on the side wall 2 of
the computer host 1.
[0016] Referring to FIGS. 3B and 3C, when in use for assembly, the
latch members 41 on the first and second side boards 10 and 20 may
be moved inwards by hands to wedge the latch spots 44 in the latch
troughs 3 on two side walls of the computer host 1 so that the
first and second side boards 10 and 20 may be coupled with the
computer host 1. For disassembly, move the latch members 41 inverse
outwards to separate from the latch troughs 3, then the first and
second side boards 10 and 20 may removed. For carrying the
computer, the connection members 30 on the upper side at the front
and rear ends may serve as handles to be grasped by user's hands
for lifting and moving. The other two connection members 30 on the
bottom at the front end and rear end may serve as pedestals resting
on the floor to prevent the computer host 1 from damping and
damaged.
