Description
BACKGROUND OF THE INVENTION
This invention relates to a portable workstool and more particularly to a portable workstool which provides for ergonomic storage and use of tools with optimum space-efficiency.
Workstools have played a very important role in many practical endeavors. Electricians, fishermen and gardeners are only three obvious examples of the nearly infinite uses of the workstool. The conventional workstool, or campstool, suffers from several deficiencies. First, it is not conveniently portable because after folding, it must be separately carried, e.g. by the frame, and so tools or other articles must be separately carried by the user. Further, any tools used must be placed on the ground or stored on some other adaptive surface. This can be inconvenient for three major reasons. First, if there is no suitable storage area for the tools nearby, it may be necessary to place them more than arm's length away, for example in an uneven or tight working space. Secondly, if the tools are placed on the ground, the user must bend over to store or retrieve the tool and such action is often ergonomically undesirable or even impractical. Third, even if the tools may be stored close by, the storage or retrieval of such tools may require visual inspection. In other words, the user may have to glance away from his work site to the general location of the tool storage area in order to retrieve or replace the tool. This is also often undesirable or even impractical with detailed work. What is needed is a workstool which is not only easily portable but one which is functionally superior to a conventional workstool by virtue of being ergonomically advantageous and space-efficient in the utilization of tools.
SUMMARY OF THE INVENTION
In accordance with the present invention, a portable workstool provides convenient portability, ergonomic storage and space-efficiency when in use. The portable workstool is suitable for carrying or use by a human subject, the stoolmember utilizing both a frame and a pad. The frame includes a firs rectangular leg and a second rectangular leg pivotally interconnected. The pad presents a die-cut pattern to form two sleeves slidably connected to the first leg and two sleeves slidably connected to the second leg. The workstool also features a detachable pouch having a substrate with a left side, a right side and a ground side, as well as first and second handles. The pouch also includes fastening structure configured to attach to the four sleeves. The left side and the right side of the pouch each contain a pocket. In preferred embodiments each pocket has a plurality of cells, e.g. three cells on each side.
In functional mode, the two legs are pivoted so that the pad is taut. The two legs are, in effect, placed on a planar surface such as the ground. The taut pad may be securely sat upon with the pouch providing ergonomic and convenient access to the pockets. The workstool is space efficient because the pockets are disposed beneath the human subject.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings in general and
FIG. 1
in particular, a portable workstool
10
is shown in accordance with the present invention. Workstool
10
includes a stoolmember
12
and a detachable pouch
14
. Workstool
10
can be carried in a portable mode or a human subject or user (not shown for ease of illustration) can sit on workstool
10
and utilize pouch
14
in accordance with the invention.
Referring to
FIG. 2
, stoolmember
12
is shown without pouch
14
(see
FIG. 1
) for clarity of illustration. Stoolmember
12
includes a frame
16
and a pad
18
. Frame
16
has a first leg
20
and a second leg
22
. First leg
20
and second leg
22
are pivotally interconnected by pins
24
. Legs
20
,
22
and pins
24
are preferably made of metal or any other suitably rigid and durable material.
First leg
20
includes a pad spar
26
, a ground spar
28
and two support members
30
. It will readily be seen that first leg
20
and second leg
22
are both rectangular in shape.
Second leg
20
includes a pad spar
32
, a ground spar
34
and two support members
36
.
An axial projection
38
of pad spar
32
of second leg
22
is shown at the right side of FIG.
2
. Likewise, an axial projection
40
of ground spar
28
of first leg
20
is also shown to the right of FIG.
2
. It will readily be seen that axial projection
38
and axial projection
40
define and present a plane
42
which is illustrated as a plane segment for ease of illustration.
An axial projection
44
of pad spar
26
of first leg
20
is shown at the left side of FIG.
2
. Likewise, an axial projection
46
of ground spar
34
of second leg
22
is also shown to the left of FIG.
2
. It will readily be seen that axial projection
44
and axial projection
46
define and present a plane
48
which is illustrated as a plane segment for ease of illustration.
Pad
18
has two first-leg sleeves
50
which are axially slidably attached to first leg
20
at pad spar
26
as shown. Pad
18
has two second-leg sleeves
52
which are axially slidably attached to the second leg
22
at pad spar
32
as shown. Pad
18
is preferably formed of a synthetic resin material, but can be made from any suitable material with or without an integrated cushion.
Referring to
FIG. 4
, second-leg sleeves
52
each include a flap
53
and respectively a male pad snap
54
a
and a female pad snap
54
b
. (Note that the first sleeves
50
have associated flaps
53
and respectively a male pad snap
54
a
and a female pad snap
54
b
; such flaps
53
, male pad snap
54
a
and female pad snap
54
b
associated with first sleeves
50
not being shown for economy of illustration; note also that directly across from male pad snap
54
a
as shown in
FIGS. 1 and 4
is female pad snap
54
b
on first sleeve
50
and that directly across from female pad snap
54
b
as shown in
FIGS. 1 and 4
is male pad snap
54
a
on first sleeve
50
.)
Although pad
18
includes structure presenting a die-cut pattern to form two first-leg sleeves
50
and two second-leg sleeves
52
, the two first-leg sleeves
50
permanently, slidably attaching first leg
20
to the remaining portions of the pad
18
, and the two second-leg sleeves
52
permanently, slidably attaching second leg
22
to remaining portions of pad
18
, all in the preferred embodiment, those skilled in the art will readily appreciate that alternative designs without a die-cut pattern could be utilized. For example, in an alternative embodiment (not shown), the first leg sleeves
50
can be formed as a single, continuous sleeve, and the second leg sleeves
52
can be similarly formed as another single, continuous sleeve. Alternatively, pad
18
can be permanently or removably attached to pad spars
20
and
22
or to itself with other suitable fastening means such as snaps, buttons, hooks or Velcro-type fasteners. Also, snaps
54
a
and
54
b
can be attached directly to pad spars
20
and
22
directly or through sleeves
50
and
52
, rather than attached to flaps
53
as shown.
Referring to
FIG. 3
, pouch
14
is shown detached from the rest of workstool
10
. Pouch
14
has a substrate
55
presenting a left side
56
, a right side
58
(see
FIG. 1
) and a ground side
60
(see also FIG.
1
).
Still referring to
FIG. 3
, pouch
14
has fastening structure in the form of two male pouch snaps
62
a
and two female pouch snaps
62
b
(note that only one male pouch snap
62
a
and one female pouch snap
62
b
, both located on left side
56
of pouch
14
are visible in
FIG. 3
due to the angle of viewing but the other male pouch snap
62
a
and female pouch snap
62
b
associated with right side
58
of pouch
14
are visible in
FIG. 1
from a different perspective). It will be readily appreciated that on both sides of pouch
14
male pouch snaps
62
a
and female pouch snaps
62
b
are disposed in complementary fashion to male pad snaps
54
a
and female pad snaps
54
b
. This arrangement of snaps allows pouch
14
to be attached to the stool facing in either direction, while permitting the same snaps
62
to be used to close pouch
14
when it is detached from the stool.
As will be readily appreciated by those skilled in the art, other numbered sets or configurations of snaps may be used and indeed other fastening structure such as velcro or buttons could be used for reversible attachment of pouch
14
to stoolmember
12
.
Left side
56
of pouch
14
includes a left handle
64
and right side
58
of pouch
14
includes a right handle
66
(see
FIG. 1
for right handle
66
). Left side
56
includes a left-side pocket
68
having three cells
70
suitable for storage. Right side
58
includes a right-side pocket
72
having three cells
74
suitable for storage. Different numbers or arrangements of cells (not shown) can alternately be provided. However, it is preferable to have individual cells rather than a large, unitary pocket to organize tools in easily accessible positions, as will be further described below.
Still referring to
FIG. 3
, when carrying workstool
10
in its fully assembled configuration, a human subject will grasp left handle
64
and right handle
66
(it will be noted that right handle
66
is not visible in FIG.
3
and furthermore that pouch
14
is not shown in conjunction with stoolmember
12
). It will be readily appreciated that when the human subject is carrying the workstool
10
, pouch
14
will be in an upright position, as substantially shown in FIG.
3
. The portable mode is beneficial because not only can workstool
10
be easily carried by handles
64
and
66
, but also tools and other objects can be carried inside pouch
14
as at reference numeral
76
illustrated in FIG.
1
. Also, items may be carried in cells
70
and
74
(see
FIG. 1
for cells
74
). In this fashion, workstool
10
can be used as a carrying case in its portable mode.
Referring to
FIG. 1
, workstool
10
is seen in its functional mode as noted above. Workstool
10
is placed in functional mode as any other conventional workstool, notably by pivotally adjusting first leg
20
and second leg
22
to form an oblique angle therebetween and ground spar
28
of first leg
20
and ground spar
34
of second leg
22
are placed on a substantially planar supportive surface such as the ground, then forces exerted by the planar surface on workstool
10
serve to maintain pad
18
in a substantially taut condition and therefore a human subject may securely sit on workstool
10
at pad
18
. In accordance with the invention, when a human user is sitting on workstool
10
he has convenient storage areas in cells
70
and
74
(see
FIG. 3
for cells
70
) as well as inside pouch
14
as shown at reference numeral
76
. Cells
70
and
74
are particularly ergonomically effective because they are at a higher elevation than the ground or other supporting planar surface so the user must not bend or reach as far to retrieve or replace tools. Furthermore, in accordance with the invention, the user can mentally designate a given cell by its position on left side
56
or right side
58
(and even its serial position with respect to the other cells on a given side) so that he may know precisely the location of a particular tool whenever he is ready to retrieve it. Hence, the user is not required to break visual contact with his work site if this is undesirable but may instead readily locate the tool by touch.
Finally and in accordance with the invention, the user need not utilize any further volume than already required by workstool
10
in its functional mode for storage of tools. As seen in
FIG. 2
, substantially parallel planes
42
and
48
describe the outer perimeter of the volume of workstool
10
in functional mode and it will be readily noted that in the preferred embodiment cells
70
and
74
are disposed between planes
42
and
48
and below the human subject when he is sitting on workstool
10
. Hence, the volume already required for workstool
10
in functional mode may also be utilized for tool storage.
While this invention has been described with reference to the specific embodiments disclosed herein, it is not confined to the details set forth and the patent is intended to include modifications and changes which may come within and extend from the following claims.
