[0001] This invention relates to a device for displaying a sheet of artwork such as a print,
poster, advertising material, photograph, or any other material which may be inserted
in a picture frame.
[0002] In our UK patent application GB-A-2 160 347 we have described such a device, comprising
a backing board surrounded by a frame, at least one side of the frame being removable
to allow a sheet of artwork to be inserted in a direction parallel to the backing
board.
[0003] The removable side of the frame is held in place solely by fingers which are provided
adjacent its ends and which are a sliding fit in channels provided in the adjacent
sides of the frame. This requires the sides of the frame to be of complicated cross-sectional
shape. Also, problems of fitting or removing the removable side may arise through
misalignment of the fingers and grooves. It is also difficult to reconcile the need
for accurate location of the removable side with the need for easy fitting and removal.
[0004] The present invention provides a device in which the removable side of the frame
is fixed to the corresponding edge portion of the backing board by releasable means
independent of the remainder of the frame.
[0005] Preferably the releasable means comprises one or more snap fitting connectors on
the removable frame side and the corresponding edge portion of the backing board.
Such connectors may, for example, be of the ball-catch type or ball-and-socket type.
[0006] The invention will be described further, by way of example, with reference to the
accompanying drawings, in which:
Figure 1 is a front view of a device for displaying a sheet of artwork;
Figure 2 is a vertical section through the device, with the sheet of artwork in place;
Figure 3 is an enlarged fragmentary view of one corner of the device; and
Figure 4 shows an alternative frame cross-section.
[0007] The device illustrated comprises a rigid backing board 1 (with a thickness of about
9mm) surrounded by a frame 2 which is fixed to the backing board and supported by
it in use, when the backing board 1 is secured to a wall or other site location by
means of screws passing through countersunk holes 3. The shorter sides 4 and the lower
side 6 of the frame 2 are permanently or semi-permanently fixed to the backing board
1 (and to each other), e.g. by glueing and/or pinning. The upper side 7 of the frame
is removable and its mitred ends 8 simply bear against corresponding mitred ends 9
of the side 4.
[0008] Two (or more) snap fitting connections in the form of ball catch connectors are spaced
along the side 7 and the corresponding upper edge of the backing board 1. A single
snap fitting connection may be sufficient instead. Each connector comprises a downwardly
widening element 11 fixed on the side 7 and a double ball catch 12 fixed in a recess
13 in the upper edge of the backing board 1. The action of the balls 14 on the element
11 urges the side 7 downwards, thereby pressing its ends 8 against the corresponding
ends 9 of the sides 4, these ends co-operating to locate the side 7 accurately in
conjunction with the connectors 11/12. At the same time the side 7 may abut against
the upper edge of the backing board 1, but there will normally be a slight gap between
them.
[0009] The frame section has a front flange 16 from which the backing board 1 is spaced
rearwardly to define a peripheral internal frame channel 17 for receiving and locating
a transparent sheet 18 (e.g. glass or plastic) and a sheet 19 of artwork. To facilitate
removal and insertion of the artwork, the transparent sheet 18 is removable vertically
when the upper frame side 7 is removed. (Alternatively, the sheet 18 may be fixed
in the frame.) For the same reason, the upper edge of th backing board 1 has a recess
21 which is overlapped by the artwork sheet 19. pads 22 on the rear of the frame 2
space the frame from the site location, in order to prevent mutual damage to the frame
side 7 and the site location during removal and fitting of the side 7.
[0010] Various modifications may be made within the scope of the invention. For example,
Figure 4 shows a modified frame section having a rear flange 23 which abuts the rear
of the backing board 1, thereby providing a more robust construction and improved
location of the removable upper frame side 7.
[0011] If required the ends of the side 7 may be provided with downwardly projecting elements
received in corresponding guides in the sides 4.
[0012] The elements 11 may be fixed on the backing board and the ball catches 12 on the
side 7.
[0013] The side 7 may be releasably connected to the backing board by other means than those
described above. For instance a sliding connection such as a dovetail joint or tongue
and groove joint may be provided so that the frame side is removable by sliding it
along the edge of the backing board; in this case at least one end of the removable
side would be so arranged as to be unimpeded by the adjacent frame side.
[0014] If desired, more than one of the sides of the frame may be made removable, since
the basis of the support for the artwork is the rigid backing board, which is fixed
to the site location. One or more of the non-removable frame sides (if any) may themselves
be fixed on the site location.
[0015] Instead of screws passing through countersunk holes, the device may be fixed to the
site location by other convenient means. e.g. eyelets screwed into the backing board
and suspended from the site location.
[0016] The backing board may be fixed in the frame so as to be removable. The upper edge
of the backing board may have a single elongate recess replacing the recesses 13 and
21, or it may be cut down to the level of the recesses l3 along the whole of its length,
so that the sheet of artwork extends beyond the entire upper edge of the backing board.
1. A device for displaying artwork, comprising a backing board (1) surrounded by a
frame (2), at least one side (7) of the frame (2) being removable to allow a sheet
of artwork to be inserted in a direction parallel to the backing board (1), characterised
in that the removable side (7) is fixed to the corresponding edge portion of the backing
board (1) by releasable means independent of the remainder of the frame (2).
2. A device as claimed in claim 1, in which the removable side (7) has mitred ends
(8) which bear against corresponding mitred ends (9 of the adjacent sides (4) of the
frame (2).
3. A device as claimed in claim 1 or 2, in which the releasable means urges the removable
side (7) towards the opposite side (6) of the frame (7).
4. A device as claimed in any of claims 1 to 3, in which the releasable means comprises

connection.
6. A device as claimed in any preceding claim, in which the edge of the backing board
