Description
CROSS REFERENCE TO THE RELATED PATENT APPLICATION
[0001] This application claims the priority of the Chinese patent
application No. 200620105271.4, filing date of Jun. 30, 2006.
FIELD OF THE INVENTION
[0002] This invention involves a kind of campstool, whose armrest
position is adjustable, and such campstools can be used for leisure
life for camping, in a courtyard, a garden and so like.
BACKGROUND OF THE INVENTION
[0003] In current technique, a folding chair or a deck chair of all
kinds used for outdoor life in tour, at courtyards, gardens, etc.
mainly consists of a chair back, a chair seat, front feet, rear
feet, and armrests. The structure of such a chair normally has
following features: The bottom end of the chair back is connected
to the rear part of the chair seat with a joining piece; there is a
movable connection between the rear end of the armrest and middle
rear of the seat with a pin; the upper ends of the front foot and
the rear foot are movably joined with a pin; the front foot and the
seat are joined via pins; the upper ends of the front foot and the
rear foot are joined with movable pins; between the upper ends of
the front and rear feet there is a fastener for adjustable armrest
positioning; when in use, the fastener can secure with the armrest
reliably. As the fastener is located between the front foot and the
rear foot, there will be severe wearing between the three, and
cause structure loosing and impact the chairs' stability and use
performance. Besides, the fastener of armrest positioning set
between the front and rear feet increases the chair width and
difficulty in chair assembly, which is unfavorable for product
packing and transportation, and the chair storage will occupy more
space. These draw out attentions to improvement of the product
stability and use comfortability.
SUMMARY OF THE INVENTION
[0004] This invention aims at designing an armrest
positioning-adjustable campstool, which is simple, compact in
structure, and easy, flexible in use.
[0005] To realize the purpose, the campstool is designed to have a
chair back, a chair seat, a front foot, a rear foot, and armrests;
the bottom part of the chair back joints the seat with a joining
piece; there is a movable connection between the rear end of the
armrest and the chair back; the front foot connects the chair back
with bolts, there is a stop piece, its one end is turnable in
connection with the chair seat at the middle back by a bolt, its
other end is connected with a positioning pin. It has such features
that the upper part of the said front and rear feet is connected
with the fastener for adjustable armrest positioning, and the
fastener fits with the armrest.
[0006] Compared with the current technique, such a structure of the
upper end of the front and rear feet connecting with the fastener
for adjustable armrest positioning permits the front and rear feet
to be at the same plane, and therefore the campstool is more
compact in structure, easier in installation, more convenient for
folding and developing, and favorable for packing and
transport.

[0012] Bellow is the detailed description as per the figure:
[0013] Refer to FIG. 1 and FIG. 2: This invention involves chair
back 1, chair seat 6, front foot 7, rear foot 9 and armrest 3. The
bottom end of said back 1 is connected with the rear of the seat 6
with the joining piece 10; there is a movable bolting connection
(bolt 2) between the rear end of the armrest 3 and the back 1; the
front foot 7 connects seat 6 via bolt 5; the stop piece 11, its one
end is turnable in connection with the seat 6 at the middle rear of
the seat 6 by a bolt 8, its other end is turnable in connection
with the rear foot 9 by a positioning pin; the upper end of the
front foot 7 and rear foot 9 is connected with fastener for
adjustable armrest positioning 4, the fastener 4 can fit with
armrest 3; the said fastener 4 is an integral member with
functional parts of positioning embedded joint 14, front foot
connecting hole 16, and rear feet connecting slot 17; the said
positioning embedded joint 14 can fit with armrest 3; the said
connecting hole 16 can fit with the upper end of the front feet 7,
and the two are connected with a bolt; the upper end of said rear
foot 9 can fit with rear foot connecting slot 17, the two have a
movable connection via bolt 13; the fit method between armrest 3
and positioning embedded joint 14 is public-known and unnecessary
to give details.
[0014] The cross section of the said armrest 3 is of "U" shape; the
underside of the armrest 3 has an open 34, and inside the open
there is an adjusting slot 31, and inside the adjusting slot 31
there are two limit stops 32 which are parallel to each other to
form a travel limit groove 33.
[0015] When the positioning embedded joint 14 of the fastener 4 is
locked into the corresponding travel limit groove 33 the chair back
1 is fixed a position. The inclination of the chair back 1 can be
adjusted in the following way: First pull the front end of the
armrest 3 upwards to separate the positioning embedded joint 14
from the travel limit groove 33, then hold the right and left
armrest 2 to move the chair back 1 to the required inclination;
after that press the armrest 3 onto the positioning embedded joint
14, and permit the positioning embedded 14 to interlock with the
adjusted limit groove 33.
[0016] In FIG. 3, the front side of said seat 6 can join with
extension seat 20 with a joining piece 19; there is a front brace
21 on the said extension seat 20, the two have movable connection
by a public-known method.
[0017] It is due to such a reasonably designed structure of the
upper end of the front foot 7 and rear foot 9 connecting with the
fastener for the armrest adjustable-positioning 4 that allows the
campstool to be more compact, easier in installation and thus
lowers the cost of installation, packing and transportation, and
improves its stability and prolong its service life. Besides, this
invention has an extension seat 20, which is optional for users so
as the campstool can also be used as a deck chair.
