Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a display shelf device, and
more particularly to a rotatable and adjustable display shelf
device for allowing shelf members to be rotated or adjusted
relative to the support posts to different angular positions.
[0003] 2. Description of the Prior Art
[0004] Typical display shelf devices comprise one or more shelf
members to be supported between two or more posts to at different
heights or positions, for supporting various objects or goods on
the shelf members.
[0005] For example, U.S. Pat. No. 6,021,908 to Mathews discloses
one of the typical display shelf devices which comprise one or more
extensible shelf members to be supported between two or more posts
to at different heights or positions.
[0006] However, the shelf members may not be adjusted relative to
the posts to different angular positions, such that the various
objects or goods may not be adjustably supported on the shelf
members at different angular positions relative to the support
posts.
[0007] U.S. Pat. No. 6,158,600 to Ferrucci et al. discloses another
typical display shelf device, which comprises one or more shelf
members that may be supported between two mounting bars at
different angular positions relative to the support posts by a
number of pivoting mechanisms. The mounting bars are required to be
secured to the support posts by a number of corner assemblies.
[0008] However, it is inconvenient to adjust the shelf members
relative to the mounting bars and the support posts to different
angular positions.
[0009] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages of the conventional display shelf
devices.
SUMMARY OF THE INVENTION
[0010] The primary objective of the present invention is to provide
a rotatable and adjustable display shelf device for allowing the
shelf members to be easily rotated or adjusted relative to the
support posts to different angular positions.
[0011] In accordance with one aspect of the invention, there is,
provided a display shelf device comprising a support post, a shelf
member, and a coupler including a ring member attached to the
support post, a bracket attached to the shelf member, a fastener
securing the bracket and the ring member together, and means for
adjustably retaining the bracket to the ring member at selected
angular position. The bracket and thus the shelf member may be
easily and quickly rotated or adjusted relative to the ring member
and thus the support post at any selected or suitable angular
positions.
[0012] The adjustably retaining means includes a plurality of
depressions formed in the ring member, and at least one projection
extended from the bracket to selectively engage into either of the
depressions of the ring member, and to adjustably retain the
bracket to the ring member at selected angular position.
[0013] The ring member includes a seat provided thereon and having
the depressions formed in the seat, to receive the projection. The
seat includes a screw hole formed therein to thread with the
fastener, the depressions are formed around the screw hole of the
seat.
[0014] The ring member preferably includes two segments secured
onto the support post with second fasteners. Each of the segments
includes two end flaps secured together by the second
fasteners.
[0015] The bracket preferably further includes a second projection
extended therefrom and arranged opposite to the projection, to
selectively engage into either of the depressions of the ring
member, and to adjustably retain the bracket to the ring member at
selected angular position.
[0016] Further objectives and advantages of the present invention
will become apparent from a careful reading of the detailed
description provided hereinbelow, with appropriate reference to the
accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0022] Referring to the drawings, and initially to FIG. a rotatable
and adjustable display shelf device in accordance with the present
invention comprises one or more shelf members 30 to be rotatably or
adjustably secured to one or more support posts 20 with one or more
couplers 1.
[0023] Each of the couplers 1 includes a ring member 10 to be
secured or attached onto the support post 20. For example, each of
the ring members 10 includes two half members or segments 11, 12
each having two end flaps 18 secured together by fasteners 13. One
or both of the end flaps 18 may include a screw hole 19 formed
therein to thread with the fasteners 13, which may detachably
secure the half members or segments 11, 12 together, in order to
detachably secure the ring members 10 onto the support posts
20.
[0024] One of the half members or segments 11, 12 includes a seat
14 provided thereon and having a screw hole 16 formed therein, such
as formed in the center portion thereof, and having a number of
depressions 15 formed therein, such as formed around the center
screw hole 16 thereof.
[0025] Each of the couplers 1 further includes a bracket 31 secured
to one end of the respective shelf member 30 with such as adhesive
materials, fasteners or latches (not shown), or by welding
processes, etc., and to be secured to the ring member 10 with one
or more fasteners 17 or latches (not shown) or the like, and thus
for allowing the shelf members 30 to be secured or attached onto
the support posts 20 with the ring members 10 and the brackets 31
of the couplers 1 respectively.
[0026] Each of the brackets 31 includes an orifice 32 formed
therein to receive the fastener 17, and one or more, such as two
opposite projections 33, 34 extended therefrom, to selectively
engage into the depressions 15 of the seat 14 of the half members
or segments 11, 12 (FIG. 3), and thus to adjustably secure the
brackets 31 and thus the shelf members 30 to the support posts 20
at any selected or suitable or different angular positions (FIG.
4).
[0027] In operation, as shown in FIG. 3, when the bracket 31 and
thus the shelf member 30 are secured to the seat 14 of the segment
11 of the ring member 10 with the fastener 17, the seat 14 may be
forced toward or against the bracket 31, in order to force the
projections 33, 34 of the bracket 31 into the depressions 15 of the
seat 14 of the segment 11, and so as to secure the brackets 31 to
the support posts 20 at selected or suitable angular position (FIG.
4).
[0028] When it is required to adjust the shelf member 30 relative
to the support posts 20 to the other selected or suitable angular
positions, the fastener 17 is unthreaded relative to the bracket
31, in order to disengage the projections 33, 34 of the bracket 31
from the depressions 15 of the seat 14 of the segment 11, and thus
for allowing the brackets 31 to be rotated or adjusted relative to
the segment 11 of the ring member 10 to any selected or suitable
angular positions (FIG. 4).
[0029] When the projections 33, 34 of the bracket 31 are forced
into the depressions 15 of the seat 14 of the segment 11 again by
threading the fastener 17 relative to the bracket 31 again, the
brackets 31 may then be secured to the segment 11 of the ring
member 10 at the selected or suitable angular positions again, such
that the shelf member 30 may be easily and quickly rotated and
adjusted relative to the support posts 20 to any selected or
suitable angular positions by the fastener 17.
[0030] It is to be preferable that, as shown in FIGS. 2-4, each of
the brackets 31 includes two or more projections 33, 34 extended
therefrom, to selectively engage into the depressions 15 of the
seat 14, and thus to adjustably and solidly secure the brackets 31
and thus the shelf members 30 to the ring members 10 and thus the
support posts 20 at any selected or suitable or different angular
positions.
[0031] However, each of the brackets 31 may also include a single
projection 33 or 34 extended therefrom, which is also good enough
to selectively engage into either of the depressions 15 of the seat
14, and to adjustably secure the brackets 31 to the ring members 10
at any selected or suitable angular positions.
[0032] As shown in FIG. 5, a shelf member 30 may also be easily and
quickly rotated and adjusted relative to one of the support posts
20 to any selected or suitable angular positions by the fastener 17
of the ring member 10.
[0033] Alternatively, as shown in FIG. 6, a number of shelf members
30 may be easily and quickly rotated and adjusted relative to a
number of support posts 20 to any selected or suitable angular
positions by the fasteners 17 of the ring members 10.
[0034] Accordingly, the rotatable and adjustable display shelf
device in accordance with the present invention may be provided for
allowing shelf members to be rotated or adjusted relative to the
support posts to different angular positions.
[0035] Although this invention has been described with a certain
degree of particularity, it is to be understood that the present
disclosure has been made by way of example only and that numerous
changes in the detailed construction and the combination and
arrangement of parts may be resorted to without departing from the
spirit and scope of the invention as hereinafter claimed.
