BACKGROUND OF THE INVENTION
There are generally over a million earthquake events every year with over a thousand of
them being over magnitude 5.0, The National Earthquake Information Center (NEIC) reports
about 50 earthquakes per day. We have made great progress in building our structures to be
able to withstand most earthquakes which has helped to lower the cost in human life during
these events, however, earthquakes still cause a tremendous amount of economic damage.
Grocery and other retail stores, laboratories, lumber yards, and warehouses and almost
anyone who stores things on shelves can lose a lot of money when even a minor earthquake hits.
Many items can be damaged or destroyed when falling from the shelves on which they are
stored on. To help with this problem, it is known to add straps, bars and other barriers across the
front of the shelves; however, these fixes make the items stored on the shelves harder to access
and detract from the esthetic look of the shelves. Since earthquake events are random events,
having to put up with these disadvantages are difficult since most of the time, the protections
are not needed. Some systems require user activation on the first warning of the quake and this
is an obvious disadvantage since most earthquakes are not predictable.
There is a need for an easy to use, non-obtrusive earthquake-activated shelf security
system that is reliable, cost efficient and not esthetically distractive. There is also a need for an
earthquake-activated shelf security system that can be used with existing shelf systems.

DETAILED DESCRIPTION OF THE INVENTION
In the following detailed description of the invention, reference is made to the drawings
in which reference numerals refer to like elements, and which are intended to show by way of
illustration specific embodiments in which the invention may be practiced. It is understood that
other embodiments may be utilized and that structural changes may be made without departing
from the scope and spirit of the invention.
Referring to figures 1, 2 and 1 9A and 19B an earthquake-activated shelf security system
100 is shown having a pair of guide rails 105 that are located on either side of a shelf 120. A
retainer 11 5 has a looped end 110 that is rotably held in place on each of its ends. As looped
end 110 engages with guide rail 105, it is free to rotate as well as moving in and out as shown in
position A and then to position B, Of course an infinite number of positions are available and the
two positions shown are not meant to limit this disclosure, In the embodiment shown, looped
end 110 fits within a hollow portion of retainer 11 5 which allows this movement, Of course
other means of allowing movement are useable as long as the desired movement is achieved,
Other means include, but not limited to, bushings, bearings, pistons, etc. as is known in the art,
(n the embodiment shown, the shank portion of looping end 110 is long enough so that even if
one side of retainer 11 5 were at a different height than the other; looped ends 100 would not
fall out. This length may be different depending on the height of the shelf protected by the
instant invention,
Now referring to figures 1, 2 and 7A and 7B, a back stop 3.95 is provided to allow the user
to adjust the sensitivity by sliding back and forth along a retainer rest portion 198. The further
from the front back stop 195 is placed (position A), the more shaking required to activate it.
Likewise, as back stop 195 is moved forward (position B), the less shaking is required to activate.
Additionally, back stop 195 provides the user with a convenient way to reset after activation,
Again with reference to figures 1 and 2, a retainer stop 125 is provided to limit the travel
of retainer 11 5 as it moves along guide rail 105. Retainer stop 125 is user moveable by sliding up
and down along guide rail 105. Retainer stop 125 is made of a compressible material like rubber
or other material which frictional makes contact with guide rail 105 yet still allowing the user to
move it to a selected position depending on what is being stored on shelf 120. Of course other
194759NZ Replacement Spec 29 July 2015
retainer stops could be used such as using a set screw, pin or even permanently attached
without departing from the instant invention,
Retainer rest portion is selected to be in the range of 1 degree to 10 degrees with a
selected angle of 3 degrees from the horizontal working well in many environments. The steeper
the angle, the more sensitive to shaking; however, if the angle is too great, the system may be
accidentally activated. In the embodiment shown, fasteners 130 are used to secure guide rails
105 to shelf 120 as is known in the art. If desired, a top faster may be used to secure the upper
portion of guide rail 105 to the lower portion of another guide rail 105. Additionally, a tab slot
may be used to hold the upper portion without actually using a fastener. The tab slot is a channel
that is shaped to hold the top portion of the guide rail.
As is shown in figure 2, retainer 115 is shown activated after an earthquake. Retainer 11
is now in place to prevent any items (not shown) stored on shelf 120 from falling.
Now referring to figures 3 and 4, earthquake-activated shelf security system 100 is
shown having multiple retainers. An upper retainer 135 has an upper looped end 155 that
rotates as discussed above, A lower retainer 140 has a lower looped end 160. Upper looped end
155 has a smaller diameter opening than lower looped end 160. Lower looped end 160 fits over
and upper retainer stop 145 and continues down guide rail 105 until it is stopped by a larger
lower retainer stop 150. In this embodiment, two retainers are implemented to provide
additional protection to items stored on shelf 120 such as bottles which could tip over or roll
under a single retainer, After activation, the user simply pushes retainers 135 and 140 back up to
retainer rest 198 against back stop 195 and it is ready for the next event,
Referring now to figures 5 and 6, a mesh net 165 is connected to upper retainer 135 and
a lower retainer 140. Mesh net 165 is rolled around lower retainer 140 and then placed on
retainer rest portion 198. During an event, mesh net 165 unrolls as upper retainer 135 is stopped
by upper retainer stop 145 and lower retainer 140 continues down to lower retainer stop 150
and mesh net 165 is then in place to protect objects that would fall through if only the retainers
were used. After activation, the user rolls mesh net 165 back up and placed back in retainer rest
portion 198, Mesh net 165 is made of a netting material such as nylon or other suitable material.
Of course mesh netting 165 could also be a solid plastic or cloth sheet as long as it is flexible
enough to roll up.
Now referring to figure 8, earthquake-activated shelf security system 100 is shown
having a small retainer stop 128 that is used to increase the esthetic appeal, Retainer 115 uses a
194759N2 Replacement Spec 29 July 2015 g
small looped end 112 to interact with retainer stop 128 which allows a user to work With the
items stored on shelf 120 while minimizing any distraction caused by the system. In other ways,
this embodiment is like the ones discussed above,
Referring now to figures 9 and 10, earthquake-activated shelf security system 100 is
shown having an extra retainer stop 128 disposed close to a larger retainer stop 185. Retainer
stop 185 stops retainer 115 from falling any further when activated and retainer stop 128 is used
to further stabilize retainer 115 when activated thus preventing retainer 115 from being pushed
upward when items from shelf slide into lower retainer 140 or mesh net 165. Again, except as
discussed above, this embodiment performs like the embodiments shown in figures 1-6.
Now referring to figures 11 and 12, earthquake-activated shelf security system 100 is
shown mounted on an inside portion of shelf 122 to minimize the intrusiveness of the system by
only having a small portion of a guide rail 108 showing and retainer rest portion 198 being placed
out of the way. An intermediate portion of guide rail 108 is used to allow this configuration with
retainer rest portion 198 using the ideal angle that allows retainers 135 and 140 to continue
falling into place once activated by an earthquake.
In figures 13 and 14, earthquake-activated shelf security system 100 is shown attached
to a shelf unit 205, Although for simplicity; the system is only shown attached to one shelf, it is
understood that the system can be placed on each and every shelf, In figure 13, the system is
prepped by placing retainers 135 and 140 in retainer rest portion 198. In an earthquake, shelf
unit 205 may shake in any direction which will immediately cause retainers 135 and 140
respectively to fall along guide rails 105, Lower retainer 140 falls past upper retainer stop 145
and is stopped by lower retainer stop 185 while upper retainer 135 is stopped by upper retainer
stop 145.
Referring to figures 15 and 16, earthquake-activated shelf security system 100 is shown
using net mesh 165 which is attached between upper retainer 135 and lower retainer 140, As
discussed above/ mesh net 165 is used when additional protection is needed.
Referring now to figures 17 and 18, guide rails 105 are attached to another guide rail 105
using a bolt 132 (figure 17) or a channel bracket 134 (figure 18} attached to shelf 120, Of course
other fastening methods may be used as long as guide rails 105 are securely held in place.
The distance between guide rails 105 and shelves 120 may be adjusted by providing slots
in the portion of guide rails 105 that attach to shelves 120. Other methods of adjusting the
194759NZ Replacement Spec 29 July 2015
distance may be used including mounting adjusting brackets (not shown) or other acceptable
adjusting means as is known in the art.
The guide rails used in this invention are generally round metal bars but could be made
of other suitable materials including, but not limited to, plastic, composites, wood, etc. Again,
although round stock are used , other shapes would be usable such as hexagonal, oval or even
square stock as long as the looped ends can travel down the guide rails smoothly and reliably.
Although the instant invention has been described in relation to particular embodiments
thereof, many other variations and modifications and other uses will become apparent to those
skilled in the art.
