Definitions

• the present application relates to a shoring post, in particular to a telescoping shoring post used in systems used for construction.
• a shoring post is used to help support objects, usually a ceiling or roof.
• objects usually a ceiling or roof.
• ceilings With varying heights of ceilings, it is obviously beneficial to have a shoring post that capable of being quickly adjusted from one height to another, while at the same time ensuring a safe work environment for all workers.
• Truss systems such as those outlined in US Patent No. 6,116,567 exist, and involve screw jacks that rotate around the post to adjust the height of the post. While this is fine for small adjustments, if one wishes to extend or retract the post several feet, this could be very time consuming.
• FIG. 1 Another type of shoring post, described in Canadian Patent No. 2,249,921 , is adjustable and can be used in a system or on their own. These types of shoring posts use a screw, while others of a similar type use a pin-type assembly. While both of these allow for the post to be extended quicker than a screw-jack type, they require the use of small screws and pins, which may not only be difficult to use, but are also easily lost.
• a further prior art post is disclosed in US Patent No. 5,653,415 to Peri GmBH.
• the '415 post can be adjusted using pins for quick adjustment to the approximate height, and then a fine adjustment means.
• the problem with pins is that they can easily be lost and are an extra component that is required when erecting/disassembling the post.
• a shoring post comprising a hollow outer leg, a plurality of slots along the length of the outer leg, an inner leg dimensioned to fit within the outer leg, a tongue plate welded to one end of the inner leg, the tongue plate including a plurality of tongue members, wherein the inner leg may be rotated within the outer leg from a first position where the tongue members are fully within the outer leg, and a second position where the tongue members extend through the slot, locking the inner leg in position relative to the outer leg.
• the preferred embodiment of the shoring post includes an adjusting screw assembly, an adjusting handle, and a plurality of support pins, where the screw assembly is used for fine adjustments to the length of the post.
• Another addition to the preferred embodiment includes a plurality of grooves along the length of the inner leg and the outer leg.
• the present application therefore provides a telescoping post shore comprising: an outer tube; a plurality of slots disposed longitudinally along said outer tube; an inner tube; at least one tongue member affixed to said inner tube and projecting from said inner tube, said at least one tongue member configured to be received by said plurality of slots; wherein said inner tube and at least one tongue member are dimensioned to slide within said outer tube and said inner tube and at least one tongue member can be rotated within said outer tube to engage said at least one tongue member with at least one of said plurality of slots.

• each post 10 has an inner tube 12 and an outer tube 14.
• the inner tube 12 is adapted to extend telescopically from within the outer tube 14, as depicted in Figure 1.
• Inner tube 12 can be seen best in Figures 4, 5a, and 5b.
• inner tube 12 has a tongue plate 19 integrally connected to one end.
• Tongue plate 19 includes a plurality of tongue members 20 located along inner tube 12.
• inner tube 12 can have as few as one tongue member or could have numerous tongue members 20 vertically displaced from one another when inner tube 12 is in an supporting position.
• tongue members 20 are preferably grouped on the same horizontal plain and across from each other in one embodiment. Alternative embodiments could however include tongue members one each side of inner tube 12 at different levels.
• tongue members 20 are located at a lower end of inner tube 12. However, this is not a requirement and tongue members 20 could be at various points along the length of inner tube 12.
• Tongue members 20 extend orthogonally from inner tube 12 and are dimensioned to extend through slots 22 in outer tube 14. The tongue members 20 and slots 22 are used to make large adjustments to the post 10 very quickly.
• post 10 includes an upper outer tube 14 and a lower tube 16.
• Outer tube 14 includes a screw bore in its lower portion
• lower tube 16 includes a screw bore in its upper end.
• a adjusting screw assembly 24 is used to make fine adjustments to the length of the post 10 and includes an adjusting handle 26 and a plurality of support pins 28.
• the fine adjustment screw assembly 24 has a double thread so a single rotation will allow twice the distance, compared to a single thread.
• support pins 28 support the screw assembly 24, and the mechanism thereby can be used to finely adjust post 10.
• screw assembly 24 is located at approximately the waist height of a worker to facilitate the fine adjustment of post 10 and to ease the removal of post 10.
• the preferred embodiment also includes a post head 18 at the end of the post 10, telescoping from the inner tube 12, used for support.
• the length that the post head 18 extends from the inner tube 12 may be adjusted by any of several types of configurations, such as using a screw, or a pin-type configuration.
• a spring pin 38 is used.
• the preferred embodiment of the outer tube 14 is shown in Figures 6 to 8. As can be seen in Figure 7, the.cross section is approximately rectangular, with an opposite set of outwardly rounded corners 30, and an opposite set of inwardly rounded corners 32.
• the cross-section of the outer leg 14 is dimensioned so that the entire inner leg 12 and tongue members 20 will fit entirely within the outer leg 14, when the tongue members are located within the outwardly rounded corners 30 ( Figure 3a).
• This configuration of the outer tube 14 is not essential to the device, however it allows for recesses for the thumb and fingers.
• an outer hole 44 dimensioned to receive a support pin 28.
• FIG. 10 a square cross section can be used where tongue 20 can interact with a groove 22 (not shown in Figure 10).
• Other cross sections include a round cross section as seen in Figures 11 or 12.
• Various internal configurations for inner tube 12 are shown in Figures 11 and 12.
• Figure 13 shows the outer tube 14 having similar dimensions to the outer tube of Figure 10.
• no channels 42 need to be present.
• the embodiment of figure 2 shows two channels 42, but these are not engaged by tongue 20.
• no channels 42 need to be present at all.
• tongue 20 can still engage slots 22 when no channel 42 is present.
• slots 22 in channel 42 adds the further benefit of having a larger support area for tongue 20.
• slot 22 includes the wall of channel 42, thereby providing additional support.
• Figure 10 further illustrates the use of a tongue 20 that is comprised of a slat. This could be advantageous in circumstances such as when the tongue 20 is not at the bottom of inner post 12. However, the tongue plate 19 of Figure 5b is preferable in most circumstances, since the tongue plate 19 lies under the outer diameter of inner tube 12, thereby providing support to the complete inner post 12.
• the slots 22 in the outer tube 14 are spaced so that when the inner tube 12 may be rotated from having the tongue members 20 entirely within the outer tube 14, to having the tongue members 20 extend through the slots 22 in the outer tube, locking the inner tube 12 in place within the outer tube 14.
• the tongue members 20 travel along a non-resistant surface, to allow for easier rotation of the inner tube 12 within the outer leg 14.
• the indention also locks the tongue precisely into the support position. This prevents the accidental rotation when raised into position or when under load.
• the indentation in a preferred embodiment is located both above and below the groove in order to allow the post to be used downside-up or downside-down. Further, safety holes 41 accommodate a pin to further prevent the dislodging of tongue 20 and hence inner post 12.
• slots 22 are space every 6 inches or 15 cm to allow for the quick rough adjustment of inner tube 12 within outer tube 14. Other dimensions are also possible.
• Post 10 is therefore configured to the proper length by adjusting inner tube 12 within outer tube 14 using tongue members 20 and slots 22. Inner tube 12 and outer tube 14 are adjusted to the approximate length required for post 10. Fine adjustment can then be accomplished using a fine adjustment mechanism such as screw assembly 24 or adjustment mechanism 34.
• tongue members 20 are slid into slots 22 by rotating inner tube 12 through an angle of 45 degrees. Other rotation angles are however possible.
• the leg is of a general cylindrical shape, which allows for it to be easily rotated within the outer leg 14.
• the tongue plate 19 is welded to the bottom of the inner tube 12.
• the preferred embodiment of the tongue plate includes two tongue members 20, however a different number of tongue members may be used.
• a connector hole 40 is shown in the embodiment of Figure 4, near the opposite end of the tongue plate 19 of inner tube 12.
• a pair of safety holes 41 accommodate pins to further lock the tongue members 20 in place.
• These safety pins, along with the indentation in the slot 22 are not essential to the device, but are features added to greatly increase the overall safety of the shoring post.
• shoring post 10 there are a plurality of channels 42 located along the length of both the inner leg 12 and the outer leg 14.
• a further type of support device in a construction system may be used to engage the channels 42 to add additional support in different directions, or to attach any type of accessories or external bracing using a connector.
• channels 42 of inner post 12 align with channels 42 of outer post 14, thereby allowing accessories or bracing to be added in the same plain to both the inner post 12 and outer post 14. This is advantageous since the channels 42 can now be used along the entire length of post 10. Prior art solutions do not have this capability, and in general do not have channels 42 on inner post 12.
• the present post system therefore provides a means for faster removal or replacement for a post by providing a tongue and groove system for gross adjustment of the inner tube within the outer tube. Tongue members are affixed to inner tube 12 thereby allowing the quick removal and replacement of the post without having to find pins or align holes.
• the preferred shape of the outer tube 14 is configured for easy handling, allowing the worker's thumbs and fingers to grip the post.
• post 10 is comprised of aluminium. Other materials could be used however.
