[0001] The present invention relates to enclosure for a display system and in particular
to a hingeless assembly for a protective enclosure as part of a modular display system.
[0002] It is often necessary to provide protective enclosures for display systems such as
office directories or commercial signages. However, the requirements in terms of geometric
configurations for such enclosures are so varied such that mass production of enclosures
are hitherto not economical. As the contents of the display systems require frequent
updating, the ideal enclosure should be light and versatile to permit easy access
to the display system. Yet exposure of the display systems to the elements generally
require the protective enclosures to be sturdy, durable and weather-proof.
[0003] Prior art hingeless assembly for a display system addresses partially the requirements
of a modular display system that is economical, durable and versatile. U.S. Patent
No. 4,968,171 teaches a hingeless extrusion which combines with other hingeless extrusion
to form a multiple positionable, self-standing modular display system.
[0004] The present invention discloses a hingeless assembly for a protective enclosure incorporated
as part of a modular display system. The protective enclosure features a main frame
and an open face panel frame. While the main frame and the open face panel frame are
assembled from standardized extrusions and joints, an elongated cylindrical bead along
one of the external edges of the main frame and a semi-cylindrical elongated groove
along a corresponding edge of the open face panel frame are slidably fitted over one
another to form a modular enclosure. A gasket is disposed along the hingeless assembly
to weather-proof the enclosure. The hingeless assembly of the enclosure not only allows
the open face panel to be opened for easy access, but also seals the interior of the
display system from the elements when the open face panel is closed. As various components
of the present invention are standardized and interchangeable, economy of scale in
manufacturing the enclosure is achieved notwithstanding the myriad geometric configurations
of display systems.
[0005] For a better understanding of the present invention and as to how the same may be
carried into effect, reference will now be made by way of example to the accompanying
drawings.
FIG 1 is an exploded, perspective view of an enclosure incorporating the present invention.
FIG 1A is a front, right side, cross-sectional view of a hingeless assembly for a
display system in accordance to the preferred embodiment of the present invention.
[0006] Fig. 1 is an exploded, perspective view of a display system incorporating a protective
enclosure according to the preferred embodiment of the present invention. The enclosure
10 comprises a main frame 11 and an open face panel frame 22. The main frame 11 further
comprises a top main frame 12, a bottom main frame 14, and side main frames 16 and
18. In the preferred embodiment of the invention, all the frames are made of aluminium
extrusions or any suitable light weight material. It should be understood by one skilled
in the art that the main frames 14, 16 and 18 are preferably standardized and interchangeable.
The frames of the main frame 11 are coupled with a plurality of main frame joints
20 to form a substantially rectangular configuration. Even though the main frames
12, 14,16 and 18 are shown be single sided (having one elongated cylindrical bead
on only one side edge of the frame), it should be understood by one skilled in the
art that the present invention is equally applicable to a double sided main frame
(having one elongated cylindrical beads on each side edge of the frame). The main
frame joints 20 are standardized and interchangeable. Preferably the main frame joints
are made of either aluminum, or other suitable weather-proofing materials. Although
the main frame joints 20 are illustrated as rounded, it should not be taken as a limitation
upon the present invention. For example, a right angle joint may be substituted for
the round joint 20.
[0007] Referring again to Fig. 1, the open face panel 22 further comprises a top panel frame
24, a bottom panel frame 26, and side panel frames 28 and 30. Just as the main frame,
the panel frames are made of aluminum extrusions or any suitable light weight material.
It should be understood by one skilled in the art that the panel frames 24, 26 and
28 are preferably standardized and interchangeable. The frames of the open face panel
frame 22 are coupled with a plurality of panel frame joints 32 to form a substantially
rectangular configuration. Like the main frame joints, the panel frame joints 32 are
also standardized and interchangeable. In the preferred embodiment of the present
invention, the panel frame joints are made of suitable weather-proofing materials.
Although the main frame joints 32 are illustrated as rounded, it should not be taken
as a limitation upon the present invention. For instance, a right angle joint is interchangeable
with the round joint 32. It is also understood that the open face panel frame 22 encloses
a transparent panel which is not shown in order not to obscure the presentation of
the present invention.
[0008] It follows from the prevalent use of standardized and interchangeable extrusions
and joints in the display system that a modular enclosure fitting a large variety
of display system may be manufactured economically. It should be understood by one
skilled in the art that the present invention is versatile as the enclosures are easily
assembled and disassembled. One further advantage of the present invention will be
described below in connection with the description of the hingeless assembly.
[0009] The main frame 11 and the open face panel frame 22 are coupled in the manner illustrated
in Fig. 1A where a front, right side, cross-sectional view of a hingeless assembly
in accordance with the preferred embodiment of the present invention is illustrated.
The top main frame 12 is shown having an L-shaped cross-section having a horizontal
edge 17 and a vertical side edge 19. An elongated cylindrical bead 13 and an elongated
extending portion 15 extend outwards from the side edge 19 for slidably engaging an
elongated semi-cylindrical groove 25 of the top panel frame 24. The side edge 19 terminates
in a elongated recess channel 33 for receiving the base of a gasket (not shown). The
gasket is used for sealing the interior of the enclosure from the elements. The gasket
is preferably made from silicon, rubber or other suitable weather-proofing materials.
[0010] In Fig. 1A the top panel frame 24 has a substantially rectangular cross section.
It should be understood by one skilled in the art that a large variety of cross-sectional
configurations is possible for the top frame panel to have as long as it incorporates
an elongated semi-cylindrical groove. For an example, see the U.K. design registration
application No.
2032782 filed by the same applicant. As described briefly in the preceding paragraph, the
top panel frame has a semi-cylindrical groove 25 disposed between the top edge and
the edge facing the side edge 19 of the top main frame. The groove 25 terminates in
edges 27 and 29 respectively. While the groove 25 receives the elongated cylindrical
bead 13 in an interlocking manner, the edges 27 and 29 permit the open face panel
frame 22 to rotate around an axis which is parallel to the longitudinal axis of the
elongated cylindrical bead 13. The angle of rotation depends on (1) the depth of the
groove edges 27 and 29, and (2) the thickness of the elongated extended portion 15.
On the same edge facing the side edge 19 is disposed an elongated semi-circular channel
35 which cooperates with the elongated recess channel 33 to accommodate the gasket
(not shown) along the hingeless assembly. When the hingeless assembly in Fig. 1A is
closed, the gasket performs the weather-proofing function of the enclosure. The top
panel frame 24 also has a flange 21 and interior edge 23 for receiving one section
of a display panel (not shown). It follows from the above that the hingeless assembly
permits easy access to the interior of the enclosure. At the same time, the gasket
disposed along the hingeless assembly prevents dust, dirt and water from entering
the enclosure.
[0011] Referring again to Fig. 1, reinforce bracket assemblies 34 and 36 are optionally
employed to provide additional stability to the structure of the main frame 11 and
the open face panel frame 22 respectively. Furthermore, an assembly consisting of
a stiffener 38 and stiffener holder 40 may be used to provide rigidity to the enclosure
10. Finally a lock 42 may optionally be added to the bottom main frame 14 in order
to secure the open face panel frame 22 to the main frame 11 and to prevent unauthorized
access to the display system.
[0012] While the present invention has been described particularly with reference to Figs.
1 to 1A with emphasis on a hingeless assembly for a protective enclosure for a display
system, it should be understood that the figures are for illustration only and should
not be taken as a limitation on the invention. For example, the hingeless assembly
of the enclosure can be located along the side main frames or even the bottom main
frame. Thus, the open face panel frame may be opened from the side or from the bottom
as opposed to from the top frame as illustrated in Figs 1 to 1A. In addition, it is
clear that the apparatus of the present invention has utility in many applications
where versatile, modular and durable enclosure is required. It is contemplated that
many changes and modifications may be made by one of ordinary skill in the art without
departing from the scope of the invention as described.
