Stabilizer mechanism for computer related equipment
Abstract
A stabilizer mechanism pivotally attached to a computer casing
wall includes retractable spring loaded extension arms which, in a
stabilizing position, extend to increase the effective casing
footprint while the retractable extension arms are in a storage
position. The stabilizer is pivotable into a retraction position
within the casing. The stabilizer includes a flat panel attached so
its freedom of rotation is limited to support the casing in an
elevated position. The retractable extension arms include a
mechanism for securing them within the stabilizer. Alternatively, a
removable stabilizer is stored in a recess within the casing. In
the stabilizing position, the stabilizer is released from the
storage recess and oriented in the stabilizing position by rotating
the stabilizer until it is at right angles to its storage position.
Pressing the stabilizer into the recess locks it in position to
elevate the computer casing.

Description
TECHNICAL FIELD
[0001] The present invention relates to mechanisms for mounting
and/or stabilizing computers and computer related hardware.
BACKGROUND ART
[0002] Traditional designs for computer related equipment, e.g.,
personal computers, have evolved from the "standard" personal
computer, exemplified by the IBM-AT, to small form-factor personal
computers (PCs) such as the e-PC manufactured by Hewlett Packard
Company. This design development has resulted in many innovative
and creative designs reflecting the acceptance of such hardware in
the business and home environments. This evolution in design has
also been influenced by aesthetic considerations which were
previously considered secondary to the basic task of housing the
internal computer hardware in a functional casing unit.
[0003] Early types of personal computers were generally
characterized by horizontally mounted motherboards resulting in a
low case profile with a relatively large footprint. This was
necessitated by the PC case needing to be sufficiently large to
accommodate a motherboard, disk drives, power supplies etc. Early
expansion board topologies reinforced the popularity of this type
of case construction. However such designs consumed a significant
amount of desk or floor space and a number of design solutions were
proposed to reduce the PC footprint.
[0004] Early adaptations of known PC designs aimed at reducing the
PC footprint included mounting the PC case on its side. Such
solutions often involved simply tilting a standard PC on its edge,
or constructing the case and chassis in a vertical orientation.
Designs of the latter type are referred to as "tower"
configurations and sometimes involve the redesign of the internal
hardware topology of the computer to accommodate this
orientation.
[0005] A common problem with such configurations is that upright or
slim line computer cases can be unstable and prone to tipping. This
is particularly so if the computer is located on the floor or
perhaps if additional hardware components, for example external
disk drives etc, are located on top of the computer case.
[0006] Early simple solutions included providing a separate
resilient plastic "foot" device in the form of a cradle into which
an edge-mounted PC case was slid. Such designs are not ideal
because PC cases come in a variety of dimensions and not all feet
can accommodate every PC model. Other solutions include integrally
molding an outwardly oriented flange or rim into the base of the
tower case. Others include incorporating molded or extruded rails
mounted along the edge of the computer casing to extend the
footprint slightly. Such arrangements can increase the footprint
and improve stability. However, they may not be ideal because they
often do not provide sufficient stability and flexibility in terms
of operating functions (cooling etc). These modifications can also
interfere with aesthetic aspects of the casing as well as hamper
the ability to quickly and easily reorient the computer in a
horizontal or vertical position.
[0007] It is an object of the present invention to provide a new
and improved structure for stabilizing a PC or computer equipment,
which structure is aesthetically pleasing, non-intrusive, compact,
solid, easy to retract/extend and allows through-wall cooling
through the underside of a vertically mounted computer or hardware
component casing.
DISCLOSURE OF THE INVENTION
[0008] One aspect of the invention relates to the combination of a
casing for computer related equipment and a structure for enabling
a bottom face of the casing to be at least partially elevated
relative to a support surface for the bottom face while the
computer related equipment is in use. The structure enables the
casing to be stably mounted on the support surface while the casing
is elevated. The structure has a shape and position causing the
structure to extend beyond side walls of the casing while the
structure elevates the casing to be stably mounted so the footprint
of the casing while the computer related equipment is in use and
the casing is elevated by the structure is greater than the
footprint of the bottom face. The structure and casing are arranged
so the casing receives the structure in a position between the
sidewalls while the computer related equipment is not in use and
the casing is not elevated by the structure so that the footprint
of the casing is the same as the footprint of the bottom face.
[0009] In a first embodiment, the casing includes a recess for
receiving and holding the structure while the casing is not
elevated and while the casing is elevated. The structure is
removable from the recess and is able to be positioned (1) in a
first angular orientation while the casing is not elevated and (2)
in a second angular orientation while the casing is elevated. The
structure and recess are arranged so that (1) the structure, when
received and held at the first orientation in the recess while the
casing is not elevated has no effect on the casing bottom face
footprint and (2) the structure, when received and held at the
second orientation in the recess while the casing is elevated,
includes (a) a bottom surface that is displaced away from the
recess and casing bottom face and (b) portions on the structure
bottom surface that extend beyond the side walls. The bottom
surface of the structure is arranged to be supported by the support
surface.
[0010] In a second embodiment, the casing carries the structure.
The casing and structure are arranged so the structure is pivoted
away from the casing bottom face while the casing is elevated. The
structure is pivoted on the bottom face while the casing is not
elevated. The structure includes a portion that is arranged to be
remote from the bottom face while the casing is elevated. The
portion of the structure carries a pair of feet that can extend
beyond opposite walls of the casing at right angles to the casing
bottom face while the casing is elevated. The feet are arranged to
provide support for the casing while the casing is elevated.
[0011] In the second embodiment, an end of the structure remote
from the casing bottom face and a portion of each of the feet
preferably have co-planar surfaces for providing support for the
casing while the casing is elevated on the support surface.
[0012] Another aspect of the invention relates to a stabilizing
mechanism for a casing of computer related equipment. The mechanism
includes a stabilizer arrangement adapted to be pivotally attached
to a casing of the computer equipment. The stabilizer includes
retractable extension arms which, in a stabilizing position of the
casing, are extendable so that the effective footprint of the
casing is increased. The retractable extension arms are retractable
in a storage position. The stabilizer arrangement and the extension
arms are arranged so that the arms are pivotable into a retraction
position within the casing while the arms are retracted in the
storage position.
[0013] The stabilizer arrangement, in the stabilized position, is
preferably arranged to be pivoted into a position whereby the
substantially downward weight of the casing prevents the stabilizer
arrangement from pivoting back into the retraction position.
[0014] Preferably, the stabilizer arrangement is arranged to pivot
in a plane which is substantially perpendicular to a pivot plane
defined by the casing wall to which it is attached. The retractable
extension arms are arranged to extend in a direction substantially
perpendicular to the pivot plane.
[0015] The stabilizer mechanism preferably includes a panel having
a proximal end attached to the casing by a hinge arrangement. The
retractable extension arms are at a distal end of the panel. The
retractable extension arms are usually spring biased for achieving
the stabilizing position.
[0016] Preferably, the retractable extension arms include elongated
pins adapted to be (1) biased out of apertures in the stabilizer
arrangement in the stabilizing position, and (2) inserted into
apertures in the stabilizer arrangement so that the stabilizer
arrangement can be moved into the retraction position.
[0017] A further aspect of the invention concerns a stabilizing
mechanism for a casing of computer related equipment. The mechanism
includes a removable stabilizer arrangement adapted to be stored in
a storage recess within the casing while the stabilizer arrangement
is in a storage position. The stabilizer arrangement is arranged to
be released form the recess and activated to a stabilizing
position.
[0018] The stabilizer arrangement preferably includes an engagement
structure adapted to be releasably engaged in the storage recess
while the stabilizer arrangement is oriented in the storage
position. The stabilizer arrangement is adapted to be released from
the storage recess while in the stabilizing position.
[0019] Preferably, the engagement structure includes a pair of
resilient members joined at proximal ends to an inside face of the
stabilizing structure and includes a detent arrangement at distal
ends shaped and oriented to engage with corresponding detent
recesses located in the engagement recess when the stabilizing
structure is in the storage position and in the stabilizing
position. The stabilizing structure is typically rotatable through
substantially 90 degrees between the storage position and the
stabilizing position.
[0020] The stabilizing structure is preferably generally planar
with dimensions such that when the stabilizing structure is in the
stabilizing position, the effective footprint of the computer
casing is increased and when the stabilizing structure is in the
storage position, the stabilizing structure can be pushed into the
storage recess and retained therein by an engagement mechanism
which extends at substantially right angles therefrom and engages
corresponding parts of the engagement surface. The storage recess
is preferably shaped to receive the stabilizing structure when the
stabilizing structure is in the storage position.

DETAILED DESCRIPTION OF THE DRAWING
[0027] FIGS. 1 and 2 are views of a first embodiment of a position
stabilizer arrangement for a computer casing 10, wherein stabilizer
11 is in a retracted storage position within the computer casing.
The stabilizer 11 includes a unitary structure comprising plate 14
and tubes 8 and 9 that are at opposite ends of the plate and have
parallel axes. A shaft (not shown) extends longitudinally through
tube 8 along axis 13 and is captured in casing 10 to form a hinge
mechanism that pivotally attaches plate 14 to computer-casing wall
12. In a preferred embodiment, tube 9 of the stabilizer 11 carries
extension arms 16a and 16b, more clearly seen in FIG. 2. Arms 16a
and 16b respectively include rods 17a and 17b and circular, disc
shaped feet that are at the ends of the rods so the centers of the
rods and feet are coincident. When stabilizer 11 is stowed in
casing wall 12, arms 16a and 16b are retracted in tube 9 and the
bottom exposed face of plate 14 is co-planar with the bottom face
of wall 12. When stabilizer 11 is pivoted about axis 13 to extend
approximately 90.degree. relative to wall 12, compression spring 18
biases arms 16a and 16b beyond the side edges of plate 14, along
the axis of tube 9. Thus, the bottom face of casing 10 is pivoted
upward in response to plate 14 being pivoted and the casing
position is stabilized by arms 16a and 16b extending beyond the
edges of plate 14 and the walls of casing 10 which are
perpendicular to wall 12. In the stabilized position shown in FIG.
2, the "effective footprint" of casing 10 is increased depending on
the length of the arms 16a and 16b.
[0028] The effective footprint of the computer casing is defined as
the effective "area" which is encompassed by the base of the
computer where that area contributes to the stability of the
computer. In the simplest case where no stabilizing mechanism is
employed, the effective footprint is the area of the base of the
computer casing, or side wall (e.g., wall 12) as the case may be,
which rests on a support surface. In the prior art cases previously
discussed, the effective area can be increased by, for example, the
planar rotation of a support foot so that the foot extends
outwardly from either side of the casing. This extension is
referred to as extending the effective footprint in a direction
substantially perpendicular to the front-back axis of the computer
casing.
[0029] FIG. 1 is a cut away view of the stabilizing mechanism in a
stowed position in casing 11. In the stowed position, the
retractable extension rods 17a and 17b are pushed into the
cylindrical apertures in the distal end 15 of stabilizer 11 and the
stabilizer is pivoted about hinge axis 13 into the casing 10. The
stabilizer 11 is retained within casing 10 by a releasable catch or
similar structure (not shown). Similarly, retractable extension
arms 16a and 16b are retained within the apertures in the distal
end 15 of stabilizer 11 by a securing mechanism (not shown). The
securing mechanism for arms 16a and 16b can be a resilient catch
molded into the arm storage apertures which engage the opposite
ends of arms 16a and 16b, where circular, disc shaped feet 19a and
19b are located. Preferably, the relative geometry of stabilizer 11
and casing 10 is such that stabilizer 11 is flush with the outer
surface 12 of the casing 10 when the stabilizer is in the storage
position shown in FIG. 1.
[0030] To stabilize the computer casing 10 while the bottom face of
casing 10 is turned upwardly about an edge opposite from the edge
close to axis 13, the stabilizer 11 is pivoted into a stabilizing
position with respect to the computer casing. In this orientation,
the stabilizer 11 is positioned so that the generally vertically
directed weight of the computer casing 12 prevents the stabilizer
11 from pivoting back into the retracted position shown in FIG. 1.
This can be effected by arranging the hinge or pivot mechanism
located at the proximal end 14 of the stabilizer 11 to limit the
degree of movement of the stabilizer 11 with respect to the casing
outer wall 12. Suitable structures such as hinge limiting
mechanisms are known in the molding and construction arts to
accomplish this purpose, and are not discussed in detail.
[0031] Stabilizer 11 pivots in a plane which is substantially
perpendicular to a plane defined by the computer casing wall 12 to
which it is attached. The retractable extension rods 17a and 17b
extend in a direction substantially perpendicular to the plane
defined by the computer casing wall 12. This orientation for the
retractable extension arms provides the largest effective footprint
for a given length of retractable extension rods 17a and 17b, and
thus enhances the stability of the computer casing 10 when the arms
16a and 16b are in the stabilizing position. Other relative
orientations are feasible within the scope of the invention.
[0032] In the embodiment illustrated in FIGS. 1 and 2, the
stabilizer is in the form of a panel or plate 14 which is attached
to the computer casing at a proximal end of the plate 14 by a hinge
arrangement and has a distal end 15, where retractable extension
arms 16a and 16b are located. The retractable extension arms 16a
and 16b are biased into the stabilizing (extended) position by
springs 18. According to this construction, as soon as stabilizer
11 is pulled out of its storage recess in casing 10, the stabilizer
pivots around the axis 13. Once the distal, or outer, end 15 is
free from the storage recess, springs 18 pop the retractable
extension arms 16a and 16b out of the apertures in stabilizer 11
into the extended stabilizing position.
[0033] In the embodiment shown, the retractable extension arms 16a
and 16b are in the form of elongated rods or pins 17a and 17b
having feet 19a and 19b. The presence of feet 19a and 19b causes a
segment of the periphery of the retractable extension arms to be
co-planar with the lower surface of the distal end 15 of the
stabilizer 11 which rests on the support surface. This aids the
sideways stability of the computer casing 10. Other designs are
possible within the scope of the invention, such as incorporating
rubber feet etc. The ends of arms 16a and 16b can also incorporate
features which engage the inner wall of the storage recess in tube
9 so that the stabilizer is securely fastened in place for
shipping. Similarly, the shape of the stabilizer 11 need not be a
flat plate or panel. For example, stabilizer 11 can be generally Y
or T-shaped with the retractable extension arms located at ends of
the arms of the Y or T and the hinge being formed at the bottom of
the base. Also, depending on the desired elevation of the computer
casing, the distance between the distal and proximal ends of plate
14 of the stabilizer 11 can be increased or decreased.
[0034] A second embodiment of a stabilizing mechanism for computer
casing 10 is shown in FIGS. 3 to 5. This embodiment includes a
releasable and removable stabilizer 50 which is constructed to be
contained in a storage recess 60 in a retracted position within the
computer casing 10. In the preferred configuration shown, the
stabilizer 50 includes a plate or panel member 55 which forms part
of the outer casing wall when the stabilizer is retracted into the
casing. In the stabilizing position (shown in FIG. 4), the
stabilizer 50 releasably engages the inside of the storage recess
60 so that the elongated directions of wall 12 and panel 55 are the
same. In the illustrated embodiment, this corresponds to a relative
orientation of 90 degrees between the storage position and
stabilizing orientation of stabilizer 50.
[0035] The stabilizer 50 includes an engagement structure adapted
to releasably engage with storage recess 60 in wall 12 when the
stabilizing means 50 is in the storage position of FIG. 3 and the
stabilizing position of FIG. 4.
[0036] In the embodiment shown, the engagement structure includes a
pair of resilient panel members 51a and 51b having proximal edges
(not visible in the Figures) connected to the inner face of panel
55. Members 51a and 51b have distal edges where detents 52a and 52b
are located. Detents 52a and 52b are shaped and oriented to engage
with corresponding detent recesses or slots 53 (see FIG. 4) located
in the engagement recess 60. In the present embodiment, the
engagement structure includes two opposing flat panels joined at
their edges to the inside surface of plate 55. Alternative
embodiments include two or more thinner flat members replacing the
single panel member 55 shown in FIGS. 3 to 5. The viability of this
construction depends on the required strength of the components of
the engagement structure, the resilience of the components and the
anticipated weight that the components need to support.
[0037] To position and secure stabilizer 50 in the support
position, the stabilizer 50 is pulled out of the storage recess 60
in the direction shown by the letter A. Stabilizer 50 is then
rotated through 90 degrees as shown by the letter B and re-inserted
into the storage recess 60. The detents 52a and 52b have the same
spacing as opposite detent recesses located inside or adjacent the
inner lip of the storage recess 60 as shown in FIG. 4 so stabilizer
50 is firmly held in situ in recess 60 such that panel members 51a
and 51b depend from wall 12 and a bottom face of panel 55 is
positioned in a plane parallel to wall 12.
[0038] In the embodiment illustrated, the resilient members 51a and
51b forming the engagement structure are molded from plastic. Thus,
members 51a and 51b "spring" into engagement when the stabilizer
structure 50 is pushed into the storage recess 60 in the
orientation shown in FIG. 4 and the detents 52a and 52b are in
registration with the detent recesses 53.
[0039] As shown in FIGS. 3-5, the preferred construction includes a
stabilizer structure 50 which is generally planar and has
dimensions such that when structure 50 is in the stabilizing
position illustrated in FIG. 4, the effective footprint of the
computer casing 10 is increased. When stabilizer structure 50 is
stored in casing 10, it is pushed into the storage recess 60 and
retained therein by detents 52a and 52b of engagement structures
51a and 51b engaging similarly located detent recesses 61a and 61b
in the inside of the recess 60.
[0040] The storage recess 60 is shaped to receive the stabilizer
structure 50 in both the storage and stabilizing position. As noted
above, recess 60 includes a further pair of detent recesses 61a and
61b which are located in the storage recess 60 toward the roof of
the recess, i.e., in the part of recess 60 that is relatively
remote from wall 12. Detent recesses 61a and 61b are oriented and
arranged to capture the detents 51a and 51b when the stabilizer
structure 50 is pushed fully into the storage recess 60. This
engagement (i.e., capturing) action retains stabilizer 50 in the
recess 60 for transport, shipping or when the computer casing 10 is
stored in an orientation where stabilizing is not necessary.
[0041] Variants of recesses 61a and 61b include providing recess 60
with finger slots or cuts (not shown). This modification assists
the user in extracting the stabilizer structure 50 from the casing
10. To this end, stabilizer structure 50 is constructed such that
the detents and recess are relatively easily engaged and disengaged
by simply pulling or pushing the stabilizer structure 50 into or
out of the storage recess.
[0042] To increase the supporting strength of the stabilizing
mechanism, the interior of storage recess 60 can include a lip or
step adjacent the detent recesses 53 so that the weight of casing
10 and the computer contents thereof is not supported entirely by
the engagement of the detents 52a and 52b and recesses 53a and 53b.
For example, the distal ends of the engagement members 51a and 51b
can bear against a solid piece of molding or part of the casing
wall 12 when the stabilizer structure 50 is oriented at 90 degrees
to the front-back axis of the casing. Other modifications to effect
this variation are possible. Other possible modifications include
forming the stabilizer structure with a different shape, e.g., with
tapering distal ends or some other shape. Similarly, the engagement
panels can be angled to the base of the stabilizer structure
instead of being at right-angles.
[0043] Thus it can be seen that the present invention provides for
aesthetically appealing and compact designs for a position
stabilizing mechanism for a casing of computer related equipment.
The mechanism is readily adaptable to modification to satisfy
different designs and appearances. Multiple stabilizing mounts can
be used in a single casing and the mechanism can also be applied to
differently shaped and oriented computer related casings. The
mechanism also prevents accidental loss of the stabilizer
structure, for example in transit or shipping. The construction is
particularly simple and effective.
[0044] Although the invention has been described by way of example
and with reference to particular embodiments it is to be understood
that modification and/or improvements may be made without departing
from the scope of the appended claims.
[0045] Where in the foregoing description reference has been made
to integers or elements having known equivalents, then such
equivalents are herein incorporated as if individually set
forth.
