[0001] The present invention concerns security apparatus which is particularly, but not
exclusively, for use in securing expensive portable items of electronic equipment,
such as lap top computers, electronic organisers, mobile telephones and similar devices.
[0002] The applicants earlier specification GB 2 336 392 discloses security apparatus comprising
a frame having a transverse portion adapted to extend across an outer surface of a
hinged lid of a lap-top computer or similar hinged lid device and also having retaining
means in the form of at least one channel arranged to receive an edge of the lid of
the computer in an open position of the lid, means also being provided on the frame
whereby it is securable to a fixed structure.
[0003] Thus, the frame may have a channel at one end of the transverse portion to fit around
one edge of the lap top lid, and a lockable moveable arm to engage around an opposing
edge, and means such as a base and/or a cable and cable securing bracket, for securing
the frame to a fixed structure.
[0004] Alternatively the frame may have a respective channel at each end ofthe transverse
portion, so that a lap top lid can be inserted between the channels, and further means
for securing the transverse portion to a fixed structure.
[0005] In both these case, the transverse portion must, of course, be closely adapted in
size to the width of the lap top computer lid. Therefore a range of different sizes
has to be provided to cater for different makes of laptop, or for other devices to
which the concept is equally applicable, such as portable electronic organisers or
game devices or mobile telephones.
[0006] An object of the present invention is to provide a modified security apparatus which
can be adapted for use with different sizes and types of equipment to be secured.
[0007] The present invention proposes security apparatus comprising a frame having a fixed
channel adapted for retaining one edge of a device to be secured, a retaining element
for engaging an opposing edge of the device, and means for securing the frame to a
fixed structure, characterised in that the retaining element provides a further channel
for reception of the opposing edge of the device and is mounted on the frame so as
to be slidably adjustable relative thereto and securable thereto in a selected position.
[0008] Preferably a portion of the frame is hollow and the retaining element is slidably
locatable therein. However, this arrangement could be reversed with the retaining
element being hollow and fitting around a portion of the frame in the manner of a
slidable sleeve.

[0010] In the drawings, parts which are concealed behind others are shown in broken lines.
[0011] Referring to Figs. 1 to 5, 10, 11 and 14 of the drawings, a first practical embodiment
of the security device of the invention comprises a frame (10), a fixed channel element
(12), a slidably adjustable retaining element (14) and a support plate (16), all ofwhich
are fabricated of steel sheet. The apparatus also comprises first and second locking
devices (17, 19).
[0012] The frame (10) comprises a large flat base (20) having a respective upstanding flange
(22), (24) at each side . Between the flanges (22, 24) there extends a slotted hollow
section (26), the profile ofwhich is quadrangular and is apparent in Fig. 3. An elongate
slot (28) extends transversely along the rear of the hollow portion (26) and inside
the hollow section (26), there is an upstanding flange (30) provided with a row of
apertures (32), as shown in Figs. 1 and 2.
[0013] The fixed channel element (12) is secured to the front of the hollow section (26),
at one end thereof, by a pair of bolts (34) which are accessible only to the front
of the apparatus. The flange (22) is disposed to the rear of the section (26) at the
same end. The channel element (12) can be detached and removed/replaced only when
there is no device mounted in the frame for securement.
[0014] The retaining element (14) is shown separately in Figs. 4 and 5. It comprises a hollow
portion (36) and an end wall (38), which is bent near the front to define a channel
(39) and extends to the rear to form a flange (40). The hollow portion (36) is in
the form of a slotted section of quadrangular profile, which is slightly smaller than
the profile of the hollow portion (26) of the frame (10) so as to be a sliding fit
therein, as is apparent in Fig. 3.
[0015] The slot (42) in the retaining element hollow section (36) is in its bottom wall,
i.e it does not coincide with the slot (28) in the hollow portion (26) of the frame
(10). The first locking device (17) in the form of a key actuated projecting style
of lock is mounted in the rear wall of the hollow section (36).
[0016] The support plate (16), shown in Figs. 10 and 11, is circular and has a substantial
pin (44) welded to the centre of one surface, which is the upper surface in use of
the apparatus. The pin (44) is formed with a groove (46). Four equally spaced holes
(48), for receiving heads of fixing bolts, are provided in the plate (16), as shown
in the drawings. Stud (45) which serves as a stop member is provided adjacent the
periphery of the plate (16) on the same surface as the pin (44).
[0017] The second locking device (19) which is shown in Figs. 1 to 3, is mounted on top
of the base (20) of the frame at a location between the flanges (22), (24). It comprises
a steel block having a cylindrical blind bore (50). A large and a small aperture (52),
(54) are formed in one wall of the block, whereby the bore (50) communicates to the
exterior. A lock barrel (56), having a tongue (58) projecting from its inner end and
also having a key actuated lateral catch, can be fitted into the bore (50). An aperture
(72) of a size corresponding to the aperture (52) in the block (19) is provided in
the base (20) of the frame (10).
[0018] Also used with the aforesaid apparatus is a circular fixing plate (60), also of sheet
steel, which is shown in Figs. 3, 12 and 13. This is formed with four apertures (62)
and corresponding threaded bushes (64) encircling these apertures on one surface,
which in use is its undersurface.
[0019] In use, the fixing plate (60) is firstly secured to the underside of a fixed surface,
such as a desk top or shelf by any conventional means (not shown). Such fixing should
take place below where the apparatus is to overlie the plate (60). The support plate
(16) is then secured through holes in the fixed surface to the fixing plate (60) by
bolts (not shown) through the apertures (48), (62) threadedly engaging the bushes
(64).
[0020] The frame (10) is then secured to the plate (16) by way of the locking device (19),
by the pin (44) locating into the aperture (52) in the block of the locking device
(19). The barrel (56) is then inserted into the bore (50). Its tongue (58) projects
into the groove (46) in the pin (44) and it is locked in this position by key actuation
at its free end causing the catch (not shown) to project laterally into the second
smaller aperture (54) in the block. Because of the location of the tongue (52) in
the groove (46) which encircles the pin (44), the frame (10) is able to rotate relative
to the plate (16) while being secured thereto. As shown in Fig. 14, the base (20)
of the frame (10) has a peripheral margin cut away, so as to expose a peripheral margin
(16A) of the support plate (16) through an angular extent of about 120°. The stud
(45) projects from the peripheral margin (16A) and serves as a stop member to limit
the rotation of the frame (10) relative to the plate. (16). However, such rotation
is sufficient to allow the frame to rotate through at least 90°, as indicated by arrows
A in Fig. 14, from an initial, normal orientation facing forward.
[0021] The hollow portion (36) of the retaining element (14) is slidably (telescopically)
located in the hollow portion (26) of the frame (10), as shown in Figs. 1 and 2 in
particular. This particular illustrated embodiment is adapted in the shape and size
of the channel element (12) and of the cooperating channel (39) on the retaining element
(14) to secure a hinged lid style of electronic organiser, such as that marketed under
the name PSION (registered trade mark). When it is to be secured, the organiser device
is placed on the forwardly extending portion of the base (20), and its lid is opened
and inserted at one side into the channel of the fixed element (12). The retaining
element (14) is then pushed inwards of the hollow portion (26) until its channel (39)
snugly fits around the opposing edge of the organiser lid. At this point the locking
device (17) is actuated so that its lock bolt projects out and engages into the closest
aperture (32) in the flange (30) inside the hollow portion (26) so as to lock the
retaining element (14) in position.
[0022] The organiser device will thus be secured and can safely be left unattended with
any risk of theft very greatly reduced. Such security apparatus may therefore be extremely
advantageous for purposes of display of this sort of organiser device at point of
sale.
[0023] Referring now to Figs. 6 to 9 of the drawings, a second practical embodiment of the
security device of the invention comprises the same frame (10) with base (20), flanges
(22), (24) and hollow portion (26) as in the first embodiment, in combination with
a differently shaped fixed channel element (82), and a different retaining element
(84) compared to the first embodiment. The parts which are the same will not be described
again. The same reference numerals are used for the parts as in Figs. 1 to 3, 10,
11 and 14.
[0024] The fixed channel element (82), is larger than the element (12). It consists of a
generally rectangular web of sheet steel, which is fixed to the front of the frame
(10) by bolts (34), which are accessible only to the front of the apparatus when it
is not locked in use securing a device which would cover said bolts. When thus fixed,
the element (82) extends above the hollow portion (26) of the frame. The element (82)
has an upstanding rim (86) along its top edge and along its side edge adjacent the
channel it provides.
[0025] The retaining element (84), which is shown separately in Fig. 9, comprises a hollow
portion (88) of exactly the same profile as the position (36) in the first embodiment,
also mounting a locking device (17). However an end wall (90) is bent to a shape of
a lazy S (92) to provide two widths of channel (92) at the front in addition to a
flange (94) to the rear of the hollow portion (88). The hollow portion (88), of course,
is a sliding fit in the hollow portion (26) of the frame (10), as in the first embodiment.
[0026] This second embodiment is used in the same way as the first, but the fixed channel
element (82) and the end wall (90) of the retaining element (84) are adapted to co-operate
and fit around the edges of a lidless electronic organiser device, such as that marketed
under the name PALM (registered trade mark), or of a mobile telephone.
[0027] Referring now to Figures 15 and 16 of the drawings, a third practical embodiment
of the security device of the invention comprises a frame (100), a channel element
(112), a slidably adjustable retaining element (114) and a support plate (116), all
made of sheet steel, for example, just as the previous embodiments.
[0028] The frame (100) is somewhat different to that in the previous embodiments in that
it comprises a flat base (120) having only a single upstanding flange (122) at one
side, and a slotted hollow section (126) extending from that flange (122), above the
base. However, the hollow section (126) is additionally supported above the base (120)
by way of a hollow post (124), the interior of which is in communication with the
interior of the hollow section (126).
[0029] Inside the hollow section (126) there is still an upstanding flange (130) provided
with a row of apertures (132). At the rear of the hollow section (126) there is a
transverse slot (128).
[0030] The retaining element (114) is similar to element (14) in Figures 1 to 5, only shorter,
because this embodiment is specifically intended to secure a mobile telephone, which
is narrower than the organiser device for which the first embodiment is designed.
[0031] Both the hollow section (126) and the retaining element (114) are of very similar
quadrangular profile to the corresponding parts in Figures 1 to 5.
[0032] The support plate (116) is substantially the same as in the previous embodiments
and has a substantial pin (144) welded to the centre of its top surface, as well as
holes (148) spaced therefrom for receiving the head of fixing bolts (not shown).
[0033] A fixing plate (160) is identical to that in Figures 3 and 8 above.
[0034] A locking device (117) identical to that in the preceding embodiments is mounted
onto the rear wall of the retaining element (114).
[0035] A unique feature of this embodiment is that the locking device (117) alone serves
to secure the frame (100) to the support plate (116). Thus a second locking device
on the base (120) of the frame (100) is not required. The position and dimensions
of the hollow post (124) are such that in use it is seated directly over the pin (144)
on the support plate, as clearly shown in Figures 15 and 16. As the retaining element
(114) is slid into an engagement position, a lip (115) thereof engages into a groove
(146) in the pin (144), thereby preventing removal ofthe frame (100) from the pin
(144) in a direction axially of the pin (144). However, as in the previous embodiments,
the frame (100) is still able to rotate on the pin, relative to the support plate
(116). Once the locking device (117) is secured through one ofthe apertures (132),
of course, the retaining element (114) cannot be slid back, so the entire frame is
secured to the plate (116).
[0036] The channel element (112) is similar to that in the second embodiment (Figures 6
and 7) as it is of enlarged rectangular form, and has a rim (186) along one side and
along the top. However, it differs in one respect in that, as well as being detachable,
it is adjustably mounted on the front wall of the hollow section (126) by means of
a pair of elongate guide slots (138). To co-operate with each guide slot (138) there
is a respective guide post (136) projecting from the front of the hollow section (126)
and a respective bolt (134) engaging into an aperture in the wall of the hollow section
and a threaded bush mounted therebehind. The retaining element (114) is in fact recessed
at (119) to allow clearance for those bushes.
[0037] Adjustment of the channel element (112) enables a particularly snug fit to be obtained
when a narrow item such as a mobile phone is to be retained between the channels of
the element (112) and (114).
[0038] The foregoing are illustrative and not limitative of the scope of the invention.
Many variations are possible. In particular, in other embodiments the hollow portion
of the retaining element may fit as a sleeve over and outside the hollow portion of
the frame, instead of inside as in the illustrated embodiments. Also, the locking
device may be mounted on the hollow portion of the frame instead of on the slidable
retaining element. Also the "fixed" channel element of whatever configuration may
be formed integral with the frame or permanently secured thereto rather than being
detachable, as in the illustrated embodiments.
