Foldable hammock stand
Abstract
A foldable hammock stand comprises a curved longitudinal base
channel attached at each end to a support leg. A pair of curved
longitudinal support arms pivotally attach inward from opposing
ends of the base section to form a support construction for holding
a two-point swing style hammock. A latching mechanism in each
support arm engages with the base section to hold the support arm
in the open or operative position. A latch release in each support
arm disengages the latch from the base section to allow each
support arm to pivot in an upward arc to the upright or stored
position. A latching mechanism on each support arm engages a base
section cross member to hold the support arm in the stored position
until released back into the operative the position.

BACKGROUND OF THE INVENTION
[0004] The present invention relates to hammock stands or supports
and more particularly, to hammock stands which are readily
foldable.
[0005] Various types of foldable or collapsible hammock stands or
supports have previously been suggested in numerous patents
including 2,347,656 and 2,581,623 to Benjamin, 4,797,961 to
Pasquariello, 4,925,138 to Rawlins, 5,003,652 to Baylass, and
5,659,907 to Huang. The aforesaid patents suggest different ways of
providing a foldable or collapsible hammock stand with various
degrees of compactness, portability and ease of operation.
[0006] The foldable hammock stand of the present invention
overcomes the limitations of the aforesaid patents by providing a
quick and simple means of reducing the amount of floor space
consumed by the hammock stand in the operative position by folding
the support arms upward and inward relative to the base section,
which continues to provide a platform for the hammock stand in the
folded position. The hammock remains attached to the support arms
and is folded vertically to protect the hammock surface from the
elements.
SUMMARY OF THE INVENTION
[0007] The present invention relates to a foldable hammock stand or
support for providing means for suspending a swing style hammock
having one attachment point on each end. The object of this
invention is to provide an improved hammock stand or support.
[0008] Another object of this invention is to provide a means for
readily folding the support arms upward and inward, so that when
not in use, the hammock stand takes up less floor space and the
hammock is folded and thus less exposed to the elements.
[0009] Other objects of this invention will be readily perceived
from the following description, claims and drawings.
[0010] The present invention relates to a foldable hammock stand or
support consisting of a curved, base section channel suspended
between first and second curved ground support legs attached
perpendicularly to opposite ends of the base channel. The base
channel provides a means for pivotally attaching first and second
longitudinal support arms. The support arms include latching
mechanisms that pivot to engage the base channel. The support arms
also include a latch release mechanism for disengaging the latching
mechanism from the base channel. The support arms have latching
mechanisms for holding the support arms in the upright or "stored"
position. Attachment hooks at the outer ends of the support arms
provide means for attaching the hammock to the support arms. Thus
the present invention provides a means for supporting a hammock in
the folded out or operative position and the folded up or "stored"
position with quick conversion between the two positions.

DETAILED DESCRIPTION OF THE INVENTION
[0018] Referring now in detail to the drawings wherein like parts
are designated by like reference numerals throughout, there is
shown in FIG. 1 a foldable hammock stand including a base section
composed of a curved base channel 10 suspended between first and
second ground support members 11 attached perpendicularly to
opposite ends of the base channel 10. First and second curved
support arms 12 are pivotally attached by means of pivot pins 13 to
opposite ends of the base channel 10. The support arms 12 include
latching mechanisms 14 that pivotally engage the base channel 10 to
hold the support arms 12 in the folded out operative position shown
in FIG. 1.
[0019] The support arms 12 include a latch release member 15
remotely attached by cable or cord 16 for disengaging the latch
mechanism 14 from the base channel 10, allowing the support arms 12
to be pivoted upward and inward to the stored position shown in
FIG. 2. The support arms 12 have latching mechanisms 17 for holding
the support arms 12 in the upright stored position. Attachment
hooks 18 at the outer ends of the support arms 12 provide means for
attaching the hammock 19 to the support arms 12 in both the folded
out operative position shown in FIG. 1 and the folded up stored
position shown in FIG. 2.
[0020] The sectional view in FIG. 3 shows the preferred embodiment
of the base channel 10 consisting of a lower horizontal wall 20 and
parallel vertical side walls. 21 Extensions of the horizontal wall
20 form flanges 22 for attaching the ground support members. 11
[0021] Pivot pins 13 spaced inward from the ends of the base
channel 10 pass horizontally through apertures 23 in the vertical
side walls 21 of the base channel 10 and apertures 26 or 27 in the
vertical side walls 24 of the support arms 12 forming a pivot axis
between the base channel 10 and each of the first and second
support arms. 12
[0022] Lateral stability of the support arms 12 relative to the
base channel 10 is provided by means of spacers 25 between the
overlapping portions of the base channel 10 sidewalls 21 and the
support arm 12 sidewalls. 24
[0023] The preferred embodiment of the support arms 12 is a square
or rectangular tube of metallic material. The tubes forming the
support arms 12 are curved to match the curvature of the base
channel. 10
[0024] One end of each support arm 12 has a means of engaging with
the pivot pins 13 in the base section channel. 10 This means of
engagement can be a slot 26 in each of the support arm 12 side
walls 24 as shown in FIG. 4a or a hole 27 in each support arm 12
side walls 24 as shown in FIG. 4b.
[0025] Each support arm 12 is held in the operative position by a
first and second latching members 26 pivotally attached to first
and second cylindrical projections 27 on the outside of the upper
horizontal wall 28 of the support arm. 12 First and second
pivotally attached latch members 26 engage first and second flanges
29 on the upper outside surfaces of the side walls 21 of the base
channel 10 as shown in FIG. 5.
[0026] A flexible tensioning member 30 attached between upper
flanges 31 of the latch members 26 hold the latch members 26 in a
positive engagement position relative to base channel flanges. 29
Downward deflection of the center portion 32 of the flexible
tensioning member 30 by the latch release cord 16 activates the
latch members 26 to pivot to the disengagement position.
[0027] As each support arm 12 pivots from the operative position to
the upright stored position a latch member 33 pivotally attached to
the upper horizontal wall 28 of the support arm 12 engages a cross
member 34 between the tops of the base channel 10 side walls. 21
(FIG. 6) The latch member 33 holds the support arm 12 in the
upright stored position until the latch member 33 is pivoted upward
to the disengagement position.
