Abstract
An elastomeric mounting pad is adhered to a curved surface of a portable device. Embedded in the mounting pad is a flat piece of metal having a boss extending outside the mounting pad. One end of a fastener is connected to the boss with the other end of the fastener adapted to be connected to an non-portable object to prevent theft of the portable device.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to security devices attached to portable devices, especially portable electronic devices such as personal computers and associated hardware.
2. Description of the Related Art
Personal computers and associated peripheral equipment such as scanners, printers, document readers, etc., are sufficiently portable so that a person can carry them. Because these portable items are also valuable, as well as portable, they may be easily stolen. A number of security devices have thus been created to inhibit theft of not only the computers, but variety of portable devices which are valuable yet may be carried off by a single person. One common way of inhibiting this theft is to physically connect the portable device to a non-portable object which is too difficult for one or two persons to easily remove, thus frustrating the theft by making it too difficult to remove the connected portable and non-portable objects, or by making it too difficult to sever the physical connection between the portable device and the non-portable object.
Some of these security devices include flat, metal plates that have an adhesive on one side to adhere the plate to the side of a computer so that the plate cannot be removed without breaking the housing of the computer or other device. A threaded recess in the plate is used to attach a locking device, such as a cable, that is in turn connected to a large, non-portable structure. To remove the device requires severing the cable, or moving the large structure to which the locking device is connected, or breaking the locking device off the portable device. Each of these impedes theft.
While these security devices work well when properly installed, the rigid plates limit their use. The rigid plates make it difficult to attach the plates to a non-flat surface. An improper attachment of these rigid plates to a non-flat surface makes it easier to remove the plate so that the security device can be uncoupled from the portable device and the device stolen. There is thus a need for a security device suitable for use with not only devices having flat surfaces, but for use with devices where there is no flat surface located.
SUMMARY OF THE INVENTION
A flexible mounting pad is provided with a flat surface. Embedded in the mounting pad, preferably near the flat surface, is an enlarged head, preferably comprising a flat metal plate. A connector can extend from this embedded head to an exterior surface of the mounting pad, with the connector being adapted for connection to a security cable or other security device, which limits the movement of the mounting pad and thus limits movement of the device to which the mounting pad is attached. Preferably, the connector has a head forming a thin disk, about 1 -inch in diameter. A threaded recess can be formed in the head so that a fastener can be removably connected to the head. A weld nut works well.
A conformal security device is thus provided for a portable object. The security device preferably has a flexible, elastomeric mounting pad with a bottom surface, an opposing top surface, and sides defining a periphery of the mounting pad. A base is embedded in the mounting pad and an opening formed in the mounting pad extending from the base to one of the top or sides. Advantageously there is an adhesive on the bottom surface of the mounting pad. Preferably, the base comprises a flat piece of metal with a thicker boss containing a recess, and a fastener is inserted into and engages the recess. A connector is connected to the base and extends through the opening, so the connector can be connected to an object that is not portable.
In one embodiment, the connector comprises a tube having a first opening in a wall of the tube, the opening being large enough to pass a head of a fastener, and a second, smaller opening extending through the wall of the tube opposite the first opening. The fastener extends through the opening to engage the recess, the fastener head not passing through the second opening and instead abutting the wall opposite the first opening. A security cable passes through the tube and blocks access to the fastener head.
One important advantage of this invention is that the portable device can have a non-flat exterior surface on which the bottom of the mounting pad is placed, with the mounting pad being flexible enough to conform to the exterior surface of the electronic device, and with the adhesive interposed between the bottom of the mounting pad and the surface to fasten the mounting pad to the exterior surface.
In a further embodiment, the mounting pad comprises a plurality of strands embedded in the mounting pad. The strands can be fastened to a connector configured to be connected to an object that is not portable, or alternatively, the strands can be connected to a security cable of sufficient length to be connected to an object that is not portable.
There is thus advantageously provided a flexible mounting pad having base means inside the mounting pad for preventing removal of said base means from the mounting pad and connector means adapted for connecting the mounting pad to an object outside the mounting pad. The connector means preferably comprises a connector having an enlarged head embedded in the mounting pad and having a connecting portion extending from the mounting pad. Adhesive means on the bottom surface connect the mounting pad to another surface which can be non-flat. Preferably the security device further comprises security restraining means connected to said means inside the mounting pad, the security restraining means being connected to an object that is not portable.
There is further provided means for fastening a first surface of a flexible mounting pad to a surface of the portable device that may be combined with means for securing a connector to a base that is located inside the flexible mounting pad in a way that inhibits removal of the base from the mounting pad. For securement, means are provided for fastening the connector to an non-portable object to limit motion between the portable device and the non-portable object. The securing means preferably comprises a threaded fastener threadingly engaging the base. The base can comprise a solid part, or can comprise a plurality of strands embedded in the mounting pad.
The invention further comprises a method for securing a portable device, and includes the steps of fastening a first surface of a flexible mounting pad to a surface of the portable device by an adhesive, securing a connector to the mounting pad by fastening the connector to a base that is located inside the flexible mounting pad in a way that inhibits removal of the base from the mounting pad, and limiting motion between the portable device and a non-portable object by fastening the connector to the non-portable object. The limiting step can comprise the step of fastening a security cable to a distal end of the connector, and preferably comprises the step of fastening a threaded fastener to the base. Advantageously, the limiting step comprises the step of fastening a security cable to the non-portable object and the mounting pad. If the base comprises a sheet embedded in the mounting pad, then preferably the limiting step comprises the step of extending a connector from the sheet to an exterior of the mounting pad and adapting a distal end of the connector to be connected to the non-portable object.
In an alternative embodiment of the method, the base comprises a plurality of strands embedded in the mounting pad that converge to form a single connection, preferably within the mounting pad, and the motion limiting step comprises the step of extending the strands outside of the mounting pad and securing them to an non-portable object. Alternatively, the base can comprise a sheet embedded in the mounting pad and the securing step comprises the step of forming an engagement with the sheet.
The result of the method and apparatus is a resilient member conforming to the surface of the portable device, and adhered to the portable device by an adhered area sufficient to prevent a thief from pulling the resilient member off the portable device. A base is embedded in the resilient member sufficiently so it resists pulling out of the resilient member if a thief attempts to pull the base out of the resilient member. A connector is fastened to the base, with the connector having a distal end extending outside of the base for securement to a non-portable object. The resilient member is preferably sized to conform to a non-flat contour of the portable device, such a portable electronic equipment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 1 and 2
, a flexible mounting pad
10
has a bottom surface
12
to which an adhesive
14
is applied to adhere the mounting pad
10
to a surface
16
of a portable device
18
. A base
20
is placed inside the mounting pad
10
, preferably by embedding the base
20
in the mounting pad
10
. A post or boss
36
extends from the base
20
, and preferably extends to outside the mounting pad
10
. The mounting pad
10
advantageously has sides
24
defining a periphery of the mounting pad
10
, and a top surface
26
opposite the bottom
12
. The boss
36
can extend through any of the sides
24
or top
26
, but preferably extends through the top surface
26
. Advantageously, the base
20
and boss
36
comprise a weld nut, with the enlarged flange being formed by the base
20
and the boss
36
comprising an internally threaded boss
36
mounted to the flange or base
20
.
The base
20
is fastened to a restraining device in a variety of ways. One illustrative connection is by a conventional attachment tube which comprises a short length of tube
30
having a hole
32
in one surface through which a connector
22
passes, with the connector
22
comprising a threaded fastener in this instance. The connector
22
has a threaded end
34
that passes through the tube
30
opposite the hole
32
to engage mating threads in a boss
36
on base
20
. The connector
22
also has an enlarged head
38
that passes through the hole
32
, but not through the wall of the tube
30
opposite the hole
32
. Thus, the head
38
screws the tube
30
to the top surface
26
of mounting pad
10
. A security cable
40
passes through the tube
30
so that access to the head
38
is prevented, which in turn prevents unscrewing and removing connector
22
. The cable
40
is fastened to an object that is not readily movable, such as a desk, wall, floor or post.
In one embodiment the boss
36
terminates inside the mounting pad
10
with an opening to the exterior surface through which a connector
22
can connect to the boss
36
and base
20
. But advantageously the boss
36
extends slightly above the adjacent exterior surface of the mounting pad
10
a distance sufficient so the connection with another security device is achieved in a way that makes it more difficult to remove the security device.
For example, if the mounting tube
30
is used and the boss
36
of a weld nut terminates inside the flexible mounting pad
10
, then the tube
30
will abut the exterior surface of the mounting pad and that makes it easier to apply a removal force to the weld nut so as to cause the base
20
to be torn from the mounting pad
10
, or to bend and break the tube
30
or the connector
22
. If the boss
36
extends slightly away from the exterior surface
26
, say about 0.060 inches, then the boss
36
holds the tube
30
and security cable slightly off the surface of the mounting pad
10
and a lateral force applied to the tube
30
causes the boss
36
and base
20
to pivot in the elastomeric base
10
, allowing the base
10
to absorb and diffuse the applied removal force so as to greatly inhibit forced separation of the connection between the mounting pad
10
and the tube
30
. If the boss
36
extends too far above the exterior surface of mounting pad
10
, then a lateral force applied to the tube
30
can be applied so as to bend and break the boss
36
or the connector
22
, and makes it easier to move the base
20
relative to the mounting pad
10
so as to rip the base
20
from the mounting pad
10
.
It is believed advantageous to have the boss
36
end a distance of about 0.060 inches from the adjacent exterior surface of mounting pad
10
when a 0.75 inch diameter, 8-32 weld nut is used in a mounting pad
10
about 0.25 inches thick. Terminating the boss
36
between about 0.010 and 0.030 inches above the surface is possible in a less preferred embodiment, but less desirable as it is not believed to work as well. The exact distance can vary depending on the materials used and the manner of connecting to the base
20
in the mounting pad
10
.
The mounting pad
10
is flexible. Preferably it is made of an elastomer, such as rubber or neoprene, with a durometer of 60 shore, but could be made of other flexible materials, or of inflexible materials that are joined to provide flexibility along at least one dimension of the mounting pad
10
. Depending on the flexibility and strength of the elastomer, the dimensions will vary. The thickness must be such that the bottom surface
12
can conform to the surface
16
to which the mounting pad
10
is to be attached, and depending on the stiffness of the material, different thicknesses may be needed to achieve the desired flexibility. But the location of base
20
in the mounting pad
10
must also be such that the base
20
does not pull out of the mounting pad
10
. The edges of the pad
10
are preferably rounded or inclined sufficiently to make it difficult to grip and attempt to tear the pad
10
off the surface to which it is adhered. A radius corresponding to the thickness is believed advantageous. Thus, for a mounting pad
10
that is about 0.25 inches thick, edges with a radius of about 0.25 inches are believed suitable.
To increase flexibility while reducing pull-out, the base
20
is preferably placed adjacent the bottom surface
12
when the boss
36
extends from the top surface
26
. Preferably the base
20
is parallel to the bottom surface
12
. Basically, the distance between the base
20
and the surface that the boss
36
exits from, is the portion of the mounting pad
10
that resists the boss
36
from being pulled out of the mounting pad
10
. In order to reduce the thickness of the mounting pad
10
and increase flexibility, while also providing the greatest resistance to pull-out of the connector
22
, the connector mounting pad should be thin. Thus, thin connector mounting pads
20
are preferred, but they have to be thick enough to resist pulling the base
20
out of the mounting pad. For a 0.25 inch thick elastomeric mounting pad
10
, a distance of about 0.19 inches from the base
20
to the exterior surface
26
is believed suitable.
It is possible to form a recess in mounting pad
10
adjacent the bottom surface
12
and insert the base
20
into the recess. But preferably the base
20
is molded into the mounting pad
10
so that it is embedded in the mounting pad and has some of the elastomer between the base
20
and the exterior surface opposing the boss
36
. Thus, preferably the elastomer surrounds all sides of the base
29
, as well as surrounding all sides of the boss
36
(except for the part that extends above the elastomer surface to connect to the security cables etc.
The layer of elastomer between the base
20
and the adhered surface
12
helps absorb and disperse the removal force exerted by someone trying to break the connection of the connector
22
and base
20
with the mounting pad
10
. If the layer of elastomer is not interposed between the surface
16
and the base
20
, then the base
20
can be twisted to make removal more easy than compared to having a layer of elastomer to absorb and disperse the removal force. The layer does not have to be very thick to be effective, with a layer of about 0.030 inches thick being suitable. The A mounting pad
10
using the 3-82 steel weld nut embedded in a 2×3 inch rectangular pad, about ¼ inches thick, made of neoprene, with the base
20
separated from the back surface
12
by a thin layer of elastomer about 0.030 inches thick, is believed suitable. A layer of about 0.015 to 0.050 inches thick between the base
20
and the adhered surface
12
is workable, but less desirable for the above described embodiment. The thicknesses can vary with the specific needs.
Advantageously, the mounting pad
10
has a bottom surface
12
of at least about 3 square inches in area, because for the housings currently used on computers and related equipment, the housing will break before the mounting pad
10
is pulled off the portable device
18
. Thus, it is preferable to select the area of the bottom surface
12
, and to size the mounting pad
10
, such that the device
18
breaks before mounting pad
10
or the adhesive layer
14
breaks.
The adhesive material
14
is thus also preferably selected so that the adhesive
14
does not separate under an applied load. Rather, the strength of the adhesive material
14
is preferably selected such that the device
18
breaks or a portion of the surface
16
pulls away with the adhesive
14
.
As used herein, the reference to an adhesive
14
includes glues, epoxies, adhesives, adhesive tape, and other chemical fastening compounds. A “super glue” type of adhesive is preferred, generically known as cyanoacrylate. This is a form of super glue that sets quickly. A two-sided adhesive tape could also be used for adhesive
14
.
To ensure good adhesion between the mounting pad
10
and the surface
16
to which the mounting pad is fastened, the surface
16
is advantageously clean and slightly roughened. Cleaning with a cleaner or solvent after slightly roughening the surface with sandpaper is preferred. Alcohol can be used as a suitable cleaner for many applications, especially as it evaporates fast. A 200 grit sandpaper can be used to roughen the surface
16
.
After applying a coating of this adhesive, the mounting pad
10
must be applied in about 6 seconds or else the “super glue” adhesive cures and reduces the bonding strength. But because this super glue sets quickly it makes installation easier. Other adhesives can be used, with the surface area of the bottom
12
, and the installation time, varying accordingly.
The base
20
may be of various sizes and thicknesses, depending in part on the curvature of the surface
16
that must be accommodated by the mounting pad
10
. The smaller the base
20
the larger the variation in the contour of the surface
16
that may be accommodated. Conversely, the larger the base
20
, the smaller the variation in surface contour that may be accommodated. But as the base
20
is made smaller, it also pulls out of the mounting pad
10
easier. Thus, there is a trade-off among the size of the base
20
, the amount of surface variation that may be accommodated, and the thickness of the base
20
resisting pullout of the base
20
.
Further, the shape of the mounting pad can affect the accommodated surface variation. A long, rectangular base
20
can accommodate more surface variation along the short dimension compared to the longer dimension. A circular shaped base
20
works equally well no matter what the orientation. Further, a circular base
20
has rounded corners which avoids stress concentrations that could initiate tearing of the elastomeric base
20
. If non-circular shapes are used for base
20
, the corners are preferably rounded in order to avoid cutting and tearing the elastomeric mounting pad
10
. The bases
20
may be embedded in mounting pads
10
of corresponding shape, or of various shapes, including square, rectangular and circular pads
10
.
For the above-described mounting pad
10
, a base
20
about 0.030 inch thick, and having a circular shape about 0.75 inch in diameter is believed suitable. The thin base
20
allows the base
20
to flex slightly with the elastomeric base, while providing enough strength to diffuse large forces from the boss
36
through the base
20
into the mounting base
10
. If the base
20
is too thick or rigid, then it more readily tears out of the mounting base
10
. A thickness about {fraction (1/25)} the diameter of the metal base
20
is believed suitable for use with a 0.23 inch diameter boss
36
. Thickness to diameter ratios of as low as {fraction (1/50)} to as high as {fraction (1/15)} being believed desirable for steel weld nuts, but less preferable. Other variations are possible as a trade off among flexibility and pull-out strength can be determined given the present disclosure.
The connector
22
is also selected so that it is strong enough not to break if a thief attempts to pull the mounting pad
10
off the device
18
. Because the connector
22
is connected to a thinner connector mounting pad
12
, it may be advantageous to provide a thickened area such as boss
36
to connect to the connector
22
. This is especially so if the connector
22
is a removable connector, such as a threaded fastener. A boss
36
about ¼ inch diameter and 1 inch high, used with a steel screw about {fraction (3/16)} inch in diameter and ½ inch long, is believed suitable for the above-described preferred embodiment. As shown in
FIG. 3
, a single piece of metal can be used to form the connector and base
20
resulting in an integral boss
36
a
and base
20
.
Referring to
FIGS. 1-2
and
4
, the use of the security device is described. An adhesive
14
is applied to the bottom
12
of the mounting pad
10
. The mounting pad
10
is fastened to the device
18
, shown as a personal computer, so that a desired bond strength is achieved between the adhesive
14
and device
18
. If super glue is applied, the mounting pad
10
should be pressed against the surface
16
of device
18
within about six seconds after applying the super glue
14
. The mounting pad
10
is flexible and will conform to the surface
16
, including curves. After the adhesive is cured sufficiently to prevent removal of the mounting pad
10
, the mounting pad
10
may be secured to a non-portable object. As used herein, a non-portable object includes stationary objects like walls, posts and floors, as well as objects that are difficult for one or two persons to readily move, such as desks, large tables, large pieces of furniture, file cabinets, etc. The illustrated embodiment has a security cable
40
connected to the mounting pad
10
either through the tube
30
(FIG.
1
), through an eye of a connector
22
(FIG.
3
). A second flexible mounting pad
10
is fastened to the side of a desk
50
and connected to the cable
40
to tie the computer
18
to the desk
50
.
Other connectors
22
can be used, and other ways of fastening the non-portable objects to the base
20
can be used. For example,
FIGS. 9-10
show a further embodiment of the connector
22
in which the connector
22
comprises a cylindrical post extending from the base
20
. The distal end of the connector
22
has a hole
52
formed therein, with the hole being used to connect the connector
22
to a non-portable object. The base
20
is embedded in the mounting pad
10
(
FIG. 1
) as in prior embodiments.
In addition to providing the ability to connect to devices in areas that are not flat, the present device offers an additional advantage. When rigid connectors are used and someone attempts to remove them by force, the rigid mounting pad directly transmits the force to the housing to which the rigid connector is fastened. This rigid connector also provides a stress concentration at the edge of the rigid connector. The result is applying a force to the rigid connector typically breaks the housing at the edge of the rigid connector. With the flexible mounting pad
10
, the elastomeic mounting pad
10
acts as an energy absorber, akin to a large spring. The removal energy stretches or compresses the elastomeric mounting pad
10
and absorbs a large amount of removal energy without damaging the device
18
. Further, the elastomer is flexible and does not transmit the removal forces to a concentrated location, but instead distributes them over the flexible mounting pad
10
. The result is that when forced removal is attempted, the mounting pad
10
will flex and not break, and the surface
16
to which the mounting pad
10
is attached is at least partially shielded from damage. It takes much more force to break the housing of the device
18
if a flexible mounting pad
10
is used compared to a rigid, conventional connector of the same size.
The mounting pad
10
is connected to a security cable or other security device by a connection embedded inside the mounting pad. This contrasts to the prior art in which the connections were to a rigid plate, even if the rigid plate was in turn connected to an elastomeric layer.
A further embodiment of this invention is shown in
FIGS. 5-6
. The mounting pad
120
comprises a plurality of strands
120
a
which are embedded in the elastomeric mounting pad
10
, along a length of the mounting pad, generally parallel to the flat bottom surface
12
. An adhesive
14
fastens the mounting pad
10
to the surface
16
of device
18
. The plurality of strands
120
a
are dispersed over the width of the mounting pad
10
, with the strands converging toward one side
24
of the mounting pad
10
and being wound into a connector
120
which can comprise any of the connectors
20
discussed above, or other connectors known to those skilled in the art. But preferably, the connector
120
comprises the distal end of a security cable
140
. This resembles a frayed cord in which the frayed strands
120
a
are embedded in the elastomer mounting pad
10
, with the cords joining the cord so that the cord forms connector
120
and exits out of a side
24
of the mounting pad
10
. A similar construction could be used with the cord or connector exiting out of the top surface
26
as shown in
FIGS. 7-8
, in which the strands are dispersed in a radial pattern for embedding in the elastomeric base
10
, and exiting out the top surface. In both of these alternative embodiments, the strands
120
a
are preferably metal, such as steel and form a woven security cable
120
. The prior art is believed to have used metal cables connected to rigid plates that were in turn fastened to the portable devices, but the cables were not embedded in flexible elastomers as described herein.
The base
20
,
120
, and connectors
22
,
122
, thus advantageously provid a means for securing a flexible mounting pad
10
to a non-portable device, whether the securement is directly achieved, or by intermediate devices such as security cable
40
. Additional securement mechanisms and methods are described below.
Referring to
FIGS. 11-15
, more than one mounting pad
10
may be used to secure portable device
18
. A plurality of mounting pads
10
may be cut to a suitable size or shape, as for example, by scissors
150
, in order to fit the areas to which the mounting pad
10
is to be connected. The areas are slightly roughened and cleaned. The adhesive
12
is applied from a tube
12
a
to the bottom
12
