The present application relates to an adjustable support frame that fits various gas cylinder pallets. The adjustable support frame may include a manifold.
Gas cylinders such as pressurized gas cylinders are often purchased as individual cylinders or in packs of four or more cylinders. The packs may include as many as 6, 8, 12, 16, or even 20 cylinders. To handle and ship these cylinders as a single unit they are typically packaged together on a cylinder pallet, also sometimes referred to a cylinder pack, bundle, or cradle.
Some pallets include a permanently attached manifold system connected to the cylinders, creating a “manifolded cylinder pallet.” A single gas cylinder is usually qualified for a ten-year period, but once installed in a manifolded cylinder cradle, pack, or pallet, from which they are not typically removed, the cylinders are required to be requalified every five years. Currently, the cradle, pack, or pallet must be disassembled every five years to requalify all the cylinders contained therein. If the pack of cylinders contains carbon dioxide or nitrous oxide, or a liquid fuel gas such as propylene, propane, or acetylene the cylinder must be removed from the pack to be re-filled, which will require disassembling the cradle, pack, or pallet to fill all of the cylinders.
Disclosed herein are a plurality of embodiments of a universal support frame for a manifold such as a gas distribution manifold that may be moved from pallet to pallet regardless of the pallet's construction. Accordingly, the universal support frame is demountably attachable to the pallet. The manifold may be demountably and/or rotatably coupled to the support frame, which eliminates the need for periodic system requalification and makes cylinder replacement and/or refill easier.
One aspect of the invention is a support frame that is attachable to an article, for example, a pallet that can hold gas cylinders such as pressurized gas cylinders. The support frame includes a first support member that has a first brace and a second brace and is adjustable to move the first and second brace into engagement with the article. The support frame also includes a second support member extending from the first support member. The second support member has a third brace thereon that is slidable along the second support member to move the third brace into engagement with the article. Accordingly, the support frame provide three points of contact with the article via the braces to stabilize the support frame so that it may support another member such as an arm having a manifold connected thereto. At least one of the first, second, and third braces is preferably generally V-shaped, X-shaped, I-shaped, ]-shaped, U-shaped, or C-shaped.
The second support member may be substantially perpendicular to the first support member and be lockable thereto by a first locking mechanism that hold the first and second braces in a selected position. The third brace, which is on the second support member, may include a second locking mechanism to hold the third brace in a selected position, for example, in engagement with a piece of the article the support frame is connected to.
In one embodiment, the second support member is removable from the first support member and the first support member includes a supporting bracket extending therefrom that removeably receives one end of the second support member. The first support member may include a sleeve and slidable member, wherein the slidable member is slidable within the sleeve to adjust the length of the first support member.
In another aspect of the invention is a support frame attachable to a cylinder pallet that includes a manifold coupled thereto. The support frame includes an adjustable first support member having a first brace and a second brace and a second support member extending from the first support member. The first support member can be adjusted to move the first and second brace into engagement with the cylinder pallet and the second support member has a slidable third brace that may be slid along its length to move the third brace into engagement with the cylinder pallet. The manifold may be coupled to the second support member at an end opposite from where the second support member extends from the first support member. The support frame may also include one or more of the various features described above for the support frame attachable to an article.
In one embodiment, the support frame includes a vertical post securely, removeably connectable to an adjustable horizontal cross member that has two braces for engaging the pallet. The cross member is engageable with the pallet by spanning a gap between two parallel sides of the pallet, such as two posts or rails. The vertical post extends upwardly beyond the upper ends of any gas cylinders present on the pallet and may incorporate a slidable clamp capable of engaging and clamping to a horizontal side, post, rail, or the like of the pallet. Once adjusted to the pallet, the support frame provides three points of contact with the pallet through the two braces on the horizontal member and the third brace on the vertical post, which may be locked into place to provide a rigid platform for a cantilever arm to be mounted to the vertical post. A gas distribution manifold may be mounted to the cantilever arm.
In one embodiment, the vertical post is fixedly connected to the adjustable horizontal cross member. In another embodiment, the cantilever arm is rotatable about the vertical post of the support frame to facilitate easier removal of empty or leaking cylinders.
Another aspect of the invention is a support frame with manifold kit. The kit may include various components including: (1) an expandable first support member having a first brace, a second brace, and a support bracket for coupling the first support member to another member of the kit; (2) at least one second support member connectable to the support bracket of the first support member, but if it includes a plurality of second support members they may have differing lengths; (3) a third brace positionable on the second support member, the third brace being slidable along the second support member; (4) an arm rotatably mountable on the second support member for rotation about a longitudinal axis defined by the second support member; (5) a manifold connectable to the arm; and optionally (6) one or more hoses connectable to the manifold. In one embodiment, the kit includes up to sixteen pigtail-type hoses.
The following detailed description will illustrate the general principles of the invention, examples of which are additionally illustrated in the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements.

The third braces 136, 136′ are slidably mounted on the second support member 108 and may be positioned inside or outside the frame of the pallet. To place the third braces 136, 136′ inside the frame of the pallet, the third brace may need to be removed from the second support member 108, flipped upside down, and put back on the second support member 108. Alternately, as shown in
In one embodiment, the second support member 108 is oriented generally perpendicular to the first support member 106. Accordingly, if the first support member 106 is oriented horizontally with respect to the pallet such that its length is adjusted horizontally, the third brace 136 is adjustable vertically relative to the pallet. Alternately, if the first support member 106 is oriented vertically with respect to the pallet such that its length is adjusted vertically, the third brace 136 is adjustable horizontally with relative to the pallet.
The manifold section 102 may be removable from and/or rotatable about the support frame 104, more specifically about the second support member 108. The removability and/or rotatability of the manifold section 102 is an advantage over fixed manifold cylinder packs in that the manifold section 102 can be moved out of the way of the cylinders to make replacement and refilling of the cylinders easier. In particular, a single cylinder may be replaced or refilled without requiring the entire pack to be broken down, in particular if the cylinder is positioned on the open end of the pallet. This support frame with manifold will also eliminate the need for cylinder qualification every 5 years.

As shown in
The first support member 106 has a first end 117 and a second end 118 and includes a first brace 115 proximal the first end 117 and a second brace 116 proximal the second end 118. The first and second braces 115, 116 may be integral with the first support member 106 or may be attached thereto. In one embodiment, the first and second braces 115, 116 are welded to the first support member 106. In another embodiment, the braces 115, 116 may be attached to the first support member by a fastener, adhesive, or any other fastening mechanism known to one of skill in the art.
The first support member 106 is a two-piece telescoping support that is adjustable. The first support member may include a sleeve 110 and a slidable member 111 received in the sleeve 110. The sleeve 110 has a first end 117′ which is the first end 117 of the first support member 106 and a second end 119 that receives a first end 120 of the slide member 111. The slide member 111 also has a second end 118′ which is the second end 118 of the first support member 106. The slide member 111 is slidable within the sleeve to adjust the length of the first support member 106, which enables the first support member 106 to be adjustable to the width of the inside or outside dimensions of two adjacent posts or rails of a gas cylinder pallet. Accordingly, the slide member 111 must have dimensions that are slightly smaller than the interior dimensions of the sleeve 110. The sleeve 110 and slidable member 111 may be cylindrical, rectangular, hexagonal, or other shaped tubes, piping, channels, or posts. In another embodiment, the sleeve 110 of the first support member 106 and the second support member 108 may be a monolithic body.
The first support member 106 also includes a first locking mechanism 114 that locks the slidable member 111 to the sleeve 110. The first locking mechanism 114 may be a screw clamp that accesses the slidable member 111 through a hole 113 in the sleeve 110. In the embodiment of
The second support member 108 may be connected to the first support member 106 anywhere along its length, but is preferably connected to the sleeve 110 so that the second support member 108 does not interfere with the slidability of the slidable member 111. In one embodiment, the second support member 108 is connected to the first support member 106 proximal to the second end 119. The second support member 108 may be cylindrical, rectangular, hexagonal, or other shaped rod, tube, or pipe.
The second support member 108 has a first end 130 and second end 132. The first end 130 as discussed above is coupled to the first support member 106 and the second end 132 may be coupled to the manifold section 102. The second end 132 may include one or more bores or holes 133, best seen in
The second support member 108 may also include a slidable clamp 139 that includes the third brace 136. As seen in
The first and second braces 115, 116 and the third braces 136, 236, 136′ may be the same or different and at least on brace is generally V-shaped, X-shaped, I-shaped, ]-shaped, U-shaped, C-shaped, or the like that is open to engage the pallet. As shown in

Now referring again to
In one embodiment, the manifold 152 is adjustably connected to the arm 150 by one or more clamps, such as first clamp 169 and second clamp 170. The clamps 169, 170 may allow the manifold 152 to be held in various positions along the length of arm 150. While clamps 169, 170 are shown as the attachment members, it is not limited thereto. One of skill in the art will appreciate that various attachment members may be used to attach the manifold 152 to the arm 150, for example bolts, cables, hooks, latches, pins, screws, or any other suitable adjustable or permanent attachment member. In another embodiment, the manifold 152 may be fixedly attached to the arm.
The manifold 152 includes a plurality of ports 166, preferably along its length, that each connects to a separate hose 168 that may be connectable to a gas cylinder. The manifold 152 may also include one or more valves 164. In one embodiment, the valve 164 is positioned in one end of the manifold 152. In another embodiment, the manifold 152 may include a first valve in one end thereof and a second valve in the opposite end thereof. In another embodiment the ends of the manifold 152 may be sealed or plugged and the valve 164 may be position somewhere along the manifold's length. Positioning the valve 164 along the manifold's length may be more appropriate if the manifold 152 is not a generally cylindrical tube, but is instead a generally rectangular tube.
The arm 150 coupling the manifold 152 to the support frame 104 has a first end 154 and a second end 156. In the embodiments of
The cantilevered end 154 of the arm 150 is coupled to the second support member 108, for example, by a mount 158. In one embodiment, mount 158 is a sleeve that is slightly larger dimensionally than the second end 132 of the second support member 108 such that the mount 158 fits over the second end 132. In one embodiment, the arm 150 is demountably attached to the second support member 108. The arm 150 may also be repositionable on the second support member 108 such that in a first position 172 the arm 150 extends out over the gas cylinders and in a second position 174 the arm 150 is not over the gas cylinders. In another embodiment, the arm 150 is rotatable about the second end 132 of the second support member 108 and hence may be rotatable about the second support member's longitudinal axis A.
The mount 158 may include one hole 159 or a plurality of holes, for example holes 159, 160, that are part of a third locking mechanism 161 to lock the arm 150 in one or more positions relative to the second support member 108. In the embodiments of
Referring now to
The spring 186 and the shaft 189 of the fastener 184 are housed within a housing 182 that is attached, preferably fixedly attached, to the exterior of the mount 158. The housing 182 is positioned on the mount 158 with the fastener 184, in particular, the shaft 189 of the fastener 184 aligned with hole 159 in the mount 158 such that the shaft 189 can pass through the hole 159 for engagement with the second support member 108, for example, engagement with a bore 133. The spring 186 may be attached to a platform 190 that is movable within the housing to compress the spring 186 in response to extraction of the fastener 184 from the bore 133. The platform 190 includes a hole 191 therethrough, preferably a generally centrally located hole, that the end 192 of the shaft 189 has passed through. With the shaft 189 extending through the hole 191 in the platform 190, a nut 187 may be received on the shaft 189 and positioned against the platform 190 opposite the spring 186. In one embodiment, the platform 190 may be a channel nut.

Now that the support frame 104 is secured to the pallet 310, the manifold section 102 can be attached to the second support member 108 with the arm in a first position 172 over the cylinders. Next, the hoses 168 of the manifold 152 can be connected to the manifold 152 and to the individual gas cylinders 320. The flow of the gas from the manifold 152 to its point of use may be controlled by valve 164. The second support member 108 should be of an appropriate length to position the manifold section 102, in particular, the manifold 152, above the tops of the gas cylinders 320. In one embodiment, the second support member 108 may include a telescoping configuration that allows the length of the second support member 108 to be adjustable to a necessary height to place the manifold section 102 above the tops of the gas cylinders 320.
An outside fit of the first support member 106 is shown in
In another embodiment, the first support member 106 may be connected to the pallet 310 with the first brace 115 having an inside fit to the vertical post 114 and the second brace 116 having an outside fit to the vertical post 116, or vice versa. This configuration should be generally as stable as the other configurations described above.
