DETAILED DESCRIPTION
[0023] As will be demonstrated herein and below, a chair is provided that provides substantial clearance on the sides and at the back of the seat for an individual to comfortably sit in the chair with attached weaponry or tools.
[0024] The following diagrams are presented for illustration and it is to be noted that any dimensions and measurements illustrated represent embodiments of the chair and as such other embodiments may alter those dimensions and measurements without departing from the beneficial teachings presented herein and below.
[0025]
[0026] The chair 100 includes a back (or back member) 110, a seat 120, two retractable arm brackets 130, a base 140, and seat height and seat tilt adjustment levers 150 (just one lever illustrated in the side view of
[0027] In an embodiment, the back 110 is constructed of multiple materials, with the tapered end that is adjacent to the back of the seat 120 being constructed as an inner alcove back panel upholstered with ballistic nylon material.
[0028] In an embodiment, three-quarters of the seat 120 is upholstered in ballistic nylon from the rear and forward. The top surface of the seat is upholstered in ballistic nylon material. The front surface of the (representing ¼ of the overall seat surface area) is upholstered with standard upholstery material.
[0029]
[0030] In an embodiment, a back surface of the back 110 is upholstered with ballistic nylon material.
[0031] The base 140 includes 6 legs 141, each leg 141 having a caster 142. The base also includes a cylinder 143.
[0032] In an embodiment, each wheel 142 is a heavy duty caster.
[0033] In an embodiment, the cylinder 143 is a gas lift 500 pound capacity pneumatic cylinder.
[0034]
[0035] The back 110 includes three sections. The first section 111 extends from the top towards the seat 120 for approximately 22 inches. The second section 112 comes down 3.5 inches and then tapers from an end of the first section 111 at an angle of approximately 22 degrees and extends through the third section 113.
[0036] In an embodiment, a largest width of the seat 120 is approximately 22.5 inches.
[0037] In an embodiment, the distance between the arm brackets 130 is approximately 29.75 inches.
[0038] In an embodiment, a height of the front surface 121 of the seat 120 is approximately 3.5 inches thick.
[0039]
[0040] The back 110 is attached to the seat 120 under the seat 120 and at the back of the seat 120. There is a gap 115 that exists between a back surface of the seat 120 and a front surface of the third portion 113 of the back 110.
[0041] Each arm bracket 130 is adjustable up and down and side to side. A height adjustment mechanism 132 when activated allows the arm brackets 130 is adjust up and down through slot 133.
[0042] In an embodiment, the height adjustment mechanism 132 is a button that, when depressed, allows the arm bracket 130 to slide up and down to adjust its height through the slot 133; when the button is released it locks into the slot 133 fixing the height of the arm bracket 130 at a user-adjusted position.
[0043] In an embodiment, the height adjustment from a base of the slot 133 ranges between approximately 12 to 15 inches.
[0044] The height adjustment mechanism 132 allows the brackets 130 to adjust while in a perpendicular position to the top surface of the seat 120.
[0045] Each arm bracket 130 also includes a retractable adjustment mechanism 131 that permits the arm bracket 130 to move forward and rearward relative to a side surface of the seat 120. The range of motion is approximately 90 degrees to the rearward position from its original upright position (shown in the
[0046]
[0047] In an embodiment, the back 110 is attached under the seat 120 at the back of the seat through a ratchet mechanism 114. The mechanism 114 allows the height of the back 110 to be adjusted up or down within a range of approximately 5 inches. The
[0048]
[0049] In an embodiment, the first portion 111 of the back 110 is approximately 4.5 inches thick with an additional 0.5 inch in thickness along the back of the back 110.
[0050] In an embodiment, a distance between back edges of the brackets 130 to a front surface of the first portion 111 of the back 110 is approximately 7 inches.
[0051] The
[0052]
[0053]
[0054]
[0055]
[0056] It is noted that when the arm brackets 130 are adjustably moved forward and rearward, the seat clearance area is substantially increased for someone with attached weaponry or tools because the brackets 130 no longer exist to restrict the seat (side to side) clearance area when sitting in the chair 100.
[0057]
[0058] In an embodiment, the width of the second portion 112 is approximately 2⅜.sup.th of an inch.
[0059] In an embodiment, the seat tilt and forward to rearward adjustment lever 150 allows the seat 120 to move in a parallel manner to a surface upon which the chair 100 is placed from a range of 20.5 inches to 22.5 inches; and allows the seat 120 to tilt at an angle.
[0060] The tapering of the back 110 from the first portion 111 to the second portion 112 and the second portion 112 to the third portion 113 as well as the tapering of the seat 120 from front to back provides additional clearance area for individuals with attached weaponry or tool utility belts. The width distance between the first portion 111 vis-à-vis the second 112 and third portions 113 also provides additional clearance area. Furthermore, the adjustment of the brackets 130 still provides forward to rearward clearance area.
[0061] Also, the additional thickness of the first portion 111 provides adequate upper back support for the individual sitting in the chair 100 while having attached weaponry or utility belt with tools.
[0062]
[0063] The third portion 113 is tapered at an angle from the second portion 112 of 22 degrees that extends to the mechanism 114.
[0064] The seat 120 is tapered beginning at approximately an area on the seat 120 adjacent to the brackets 130 at an angle of approximately 35 degrees that extends to the back of the seat 120.
[0065] This illustrates the additional amount of clearance area towards the back of the seat 120 and at the back 110 for an individual with attached weaponry or a utility belt.
[0066]
[0067] In an embodiment, the third portion 113 and second portion 112 have a height extending from behind the back of the seat 120 to the first portion 111 of approximately 7 to 12 inches.
[0068] In an embodiment, the back fully tapered end of the seat 120 has a width of approximately 10.5 inches.
[0069] In an embodiment, the widest portion of the seat 120 at the front surface 121 is approximately 22.5 inches and the length of the seat 120 extending from the front to the back is approximately 20 to 25 inches.
[0070] Again, the tapered nature of the seat 120 and the back provide additional back clearance area when an individual with attached appendages (weaponry and/or tool belt) is sitting in the chair 100.
[0071]
[0072] In an embodiment, the length of the back 110 or height of the back 110 is approximately 30.5 inches. The width of the first portion 111 is approximately 22 inches, the second portion 112 is approximately 17.5 inches, and the third portion 113 is approximately 8 inches.
[0073] The third portion 113 converges adjacent to the back of the seat (which is tapered and has a reduced width as illustrated in the
[0074]
[0075] The adjustment mechanisms 150 are attached to the cylinder 143 of the base 140 and a bottom surface of the seat 120.
[0076] The adjustment mechanism 150 includes two levers 151 and 152 that extend side to side on each side under the seat 120, such that an individual sitting in the chair 100 can access with either hand one of the levers. A center portion 153 of the mechanism 150 provides stability, balance, and separates the two levers 151 and 152.
[0077] In an embodiment, the lever 152 includes a tilt tension adjustment and a seat height adjustment handle.
[0078] In an embodiment, the lever 151 includes a 4 position anti kick lock and an integrated seat slider handle, such that the seat can be adjusted front to back and tilted.
[0079] One now appreciates how substantial side to side sitting clearance area is increased through the retractable brackets 130 and how back sitting clearance is increased through the tapering of the back 110, the seat 120, the width of the third portion 113, the width of the back of the seat 120, and the gap 115 between the back of the seat 120 and front surface of the third portion 113 of the back 110. This provides substantial clearance area for an individual sitting in the chair 100 with attached appendages on his/her person (such as weaponry and utility belts with tools).
[0080] The above description is illustrative, and not restrictive. Many other embodiments will be apparent to those skilled in the art upon reviewing the above description. The scope of embodiments should therefore be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.
