Description
STORING RACK FOR CORE SAMPLE BOXES
This invention relates to a rack for the storing of core sample boxes.
BACKGROUND OF THE INVENTION
In geological exploration, large numbers of core samples are drilled from the earth to provide information concerning the earth's structure in the geological area concerned. Such a core sample may be of the order of 3000 feet in length and as it is withdrawn from the earth, it is collected in boxes so as to provide a permanent record of the earth's structure at that location.
In order to avoid transport of large number of core boxes, often in areas where there is no organized transportation, the boxes need to be stored on site for future record. It will be appreciated that after incurring the considerable expense of a core sample bore, it is highly desirable to ensure that the core sample is maintained for future study when future exploration is being carried out possibly for different reasons. The core samples are typically collected in 5 feet lengths in elongated boxes, often formed of wood or cardboard, each containing three such samples.
Racks for such boxes were traditionally been manufactured on site and are prone to twisting or warping thus, effectively locking the boxes in position in the racks. This of course renders the whole storage system totally useless since it prevents recovery of the boxes for future study without considerable effort to remove the warping. Furthermore, the manufacture of the racks on site has been a long and time consuming business with difficulty in assembling the racks initially in untwisted form and often in harsh climatic conditions.
In US patent no: 4,624,373 (Caron) issued November 24, 1986 is disclosed a rack for storing elongate core sample boxes which is formed from three separate frames each having three uprights formed of timber, cross members of timber and a plurality of aluminum tubes extending across between the uprights and passing through bores in the uprights. Each junction between a tube and an upright is locked in position by a nail passing transversely to the tube through the upright.
The frames can be transported in assembled form and then the rack completed by the application of end and top panel sheets of plywood.or the like.

DETAILED DESCRIPTION
The rack 10 for storing elongate core sample boxes B is shown in Figure 2. The boxes are arranged in rows and columns as shown in Figure 1. The rack comprises two rectangular support frames 11 and 12 each including three spaced parallel uprights or posts 13, 14 and 15 and a plurality of parallel support rails 16 welded to the uprights at spaced positions therealong and extending at right angles thereto such that the uprights and the rails lie in a common plane of the frame. The posts are formed by steel tubes and the rails 16 are tubes of a smaller transverse dimension welded to one side face of the post. The post 14 is arranged in the middle with rails on each side. This forms therefore two sections for receiving the rows of boxes.
The only connection between the posts of the frames is provided by the rails so that there is no top or bottom connection piece of a different construction or dimension to the rails. There are only two frames 11 and 12 for supporting the core boxes along their length so that they are spaced by a distance less than the length of the boxes so as to balance the boxes across the rails. Each frame is formed as a separate transportable unit defined only by the posts and the rails.
As shown in Figure 3, the frames are connected by top bridging members 16 and bottom bridging members 17. As shown in Figure 5, each bridging member comprises a tubular cross rail 18 and a pair of insert pieces 19. Thus the top bridging members 16 extend between a top of the upright 13 of one frame and a top of the upright 13 of a next adjacent frame and symmetrically the bottom bridging members 17 extend between a bottom of the upright 13 of one frame and a bottom of the upright 13 of the next adjacent frame.
The top and bottom bridging members are formed from metal tube of the same dimension as the posts. The pair of insert members 19 welded at right angles to the rail are arranged for sliding insertion into an end of the tube forming the upright. The insert members are C-shaped in cross section so that they can be pressed into the interior of the tube. The C-shape can allow the insert piece to be squeezed so as to compress to form a press fit. The insert piece can also be tapered.
The rack is completed by a pair of diagonal braces 20 across the posts of each frame extending between the top of an upright of said one frame and the bottom of an upright of said next adjacent frame. As best shown in Figure 4, the braces are formed as flat metal straps and engage the top and bottom bridging members at the rails 18 so as to hold the bridging members in engagement with the uprights thus preventing the bridging members from moving apart.
Figure 6 is a partly exploded and enlarged view of a connection between the roof truss and top bridge member of the rack of Figure 2.
In the drawings like characters of reference indicate corresponding parts in the different figures.
DETAILED DESCRIPTION
The rack 10 for storing elongate core sample boxes B is shown in Figure 2. The boxes are arranged in rows and columns as shown in Figure 1. The rack comprises two rectangular support frames 11 and 12 each including three spaced parallel uprights or posts 13, 14 and 15 and a plurality of parallel support rails 16 welded to the uprights at spaced positions therealong and extending at right angles thereto such that the uprights and the rails lie in a common plane of the frame. The posts are formed by steel tubes and the rails 16 are tubes of a smaller transverse dimension welded to one side face of the post. The post 14 is arranged in the middle with rails on each side. This forms therefore two sections for receiving the rows of boxes.
The only connection between the posts of the frames is provided by the rails so that there is no top or bottom connection piece of a different construction or dimension to the rails. There are only two frames 11 and 12 for supporting the core boxes along their length so that they are spaced by a distance less than the length of the boxes so as to balance the boxes across the rails. Each frame is formed as a separate transportable unit defined only by the posts and the rails.
As shown in Figure 3, the frames are connected by top bridging members 16 and bottom bridging members 17. As shown in Figure 5, each bridging member comprises a tubular cross rail 18 and a pair of insert pieces 19. Thus the top bridging members 16 extend between a top of the upright 13 of one frame and a top of the upright 13 of a next adjacent frame and symmetrically the bottom bridging members 17 extend between a bottom of the upright 13 of one frame and a bottom of the upright 13 of the next adjacent frame.
The top and bottom bridging members are formed from metal tube of the same dimension as the posts. The pair of insert members 19 welded at right angles to the rail are arranged for sliding insertion into an end of the tube forming the upright. The insert members are C-shaped in cross section so that they can be pressed into the interior of the tube. The C-shape can allow the insert piece to be squeezed so as to compress to form a press fit. The insert piece can also be tapered.
The rack is completed by a pair of diagonal braces 20 across the posts of each frame extending between the top of an upright of said one frame and the bottom of an upright of said next adjacent frame. As best shown in Figure 4, the braces are formed as flat metal straps and engage the top and bottom bridging members at the rails 18 so as to hold the bridging members in engagement with the uprights thus preventing the bridging members from moving apart.
Each of the braces includes at each end a slot 21 for engagement over a tab 22 such that the tab 22 extends into the slot with a portion 22A of the tab exposed beyond the brace 20 and wherein there is provided a slot shaped opening 22B in the exposed portion 22A of the tab for receiving a wedge member 23 driven into the opening to hold the exposed portion 22A tight in the slot 21 of the brace 20.
The wedge member 23 has tapered sides 23A and 23B so as to provide a wedging action between an end 22C of the slot 22B and a surface 20A
of the brace 20. The wedge member is preferably a flat metal plate so as to fit in the slot 22B.
The slot 21 extends longitudinally of the brace and the tab 22 lies at an angle to the upright 13 so as to pass through the slot.
As shown in Figure 5, the bottom bridging members 17 include foot pads 25 on an underside of the rail 18 for attachment to a supporting surface by bolt holes 25A.
As shown in Figures 1 and 2, the top bridging members 16 are attached to respective roof trusses 30 for supporting a roof panel 31 to cover the rack. The trusses 30 are tapered so as to support the roof at an inclined angle for water shedding.
Each truss 30 is attached to the rail 18 of the respective top bridging member 16 by a depending flange 35 which includes a slot 36 for engagement over a tab 37 attached to the rail 18 of the top bridging member 16. The tab 31 extends into the slot 36 with a portion 37A of the tab exposed beyond the flange 35.
There is provided an opening 38 in the exposed portion of the tab for receiving a wedge member 40 driven into the opening 38 to hold the exposed portion 37A tight in the slot 36 of the flange 35.
The structure thus includes simple pieces which can be easily and separately transported to the necessary remote location. The structure is assembled without any nuts and bolts simply by locating the tabs in the lots and by hammering the wedge into place. This simple fastening serves to square up and brace the structure and to hold the top and bottom together. The structure so formed can be carried on wooden footing rails or on piles with a simple attachment while supporting a very high load of core boxes.
The wedge member 23 has tapered sides 23A and 23B so as to provide a wedging action between an end 22C of the slot 22B and a surface 20A
of the brace 20. The wedge member is preferably a flat metal plate so as to fit in the slot 22B.
The slot 21 extends longitudinally of the brace and the tab 22 lies at an angle to the upright 13 so as to pass through the slot.
As shown in Figure 5, the bottom bridging members 17 include foot pads 25 on an underside of the rail 18 for attachment to a supporting surface by bolt holes 25A.
As shown in Figures 1 and 2, the top bridging members 16 are attached to respective roof trusses 30 for supporting a roof panel 31 to cover the rack. The trusses 30 are tapered so as to support the roof at an inclined angle for water shedding.
Each truss 30 is attached to the rail 18 of the respective top bridging member 16 by a depending flange 35 which includes a slot 36 for engagement over a tab 37 attached to the rail 18 of the top bridging member 16. The tab 31 extends into the slot 36 with a portion 37A of the tab exposed beyond the flange 35.
There is provided an opening 38 in the exposed portion of the tab for receiving a wedge member 40 driven into the opening 38 to hold the exposed portion 37A tight in the slot 36 of the flange 35.
The structure thus includes simple pieces which can be easily and separately transported to the necessary remote location. The structure is assembled without any nuts and bolts simply by locating the tabs in the lots and by hammering the wedge into place. This simple fastening serves to square up and brace the structure and to hold the top and bottom together. The structure so formed can be carried on wooden footing rails or on piles with a simple attachment while supporting a very high load of core boxes.
