This application claims priority to U.S. Provisional Application Ser. No. 62/879,793, filed Jul. 29, 2019, the entire contents of which are hereby incorporated in their entirety.
FIELD OF THE INVENTIONThe present invention is directed to an adjustable shoring beam having a fixing clamp that prevents the movement of freight. This invention is intended to be used with E-track mating features such as those found on the vertical posts and decks of a movable platform described in U.S. Pat. No. 10,279,955, issued May 7, 2019, the entire contents of which are hereby incorporated in their entirety. The adjustable shoring beam may engage surfaces containing E-track mating features which are parallel and/or perpendicular to the length of the beam.
BACKGROUNDAdjustable shoring beams are used in securing freight in trailers or on loading platforms. Current adjustable shoring beams typically rely on a rudimentary locking system, if any, to maintain the adjustable shoring beam at a fixed length. These shoring beams can be difficult to adjust. Further, the use of the adjustable shoring beams is limited to horizontal use between mating features due to their design. Therefore, there exists a need for an adjustable shoring beam that can easily be adjusted and secured in a variety of configurations.
SUMMARYDisclosed herein is an adjustable shoring beam configured to mate with E-track mating features. The adjustable shoring beam can be adjusted over a predetermined length range by adjusting the tube assembly and the rod assembly. In some embodiments, the extension length is fixed using a fixing clamp coupled to the tube assembly and the rod assembly. A connecting clamp and bracket may be used to couple a first adjustable shoring beam to a second adjustable shoring beam.
Referring to
Rod assembly 102 and tube assembly 104 are depicted as having circular cross-section. However, it should be apparent that any cross-section can be utilized as long as rod assembly 102 can slide within tube assembly. Other possible compatible cross-section shapes include square, rectangular, oval, quadrilateral, round in square, oval in rectangle, etc.
Rod assembly 102 is coupled to a first hook assembly 106 and tube assembly 104 is coupled to a second hook assembly 108. First hook assembly 106 and second hook assembly 108 are used to secure adjustable shoring beam 100 to a movable platform. Rod assembly 102, first hook assembly 106, tube assembly 104, and second hook assembly 108 are all preferably formed from steel, such as ASTM A36 steel. However, it should be obvious that any industrial grade metal (or even strong plastic) can be used in their construction.
First hook assembly 106 is preferably coupled to rod assembly 102 through welding. Similarly, second hook assembly 108 is preferably coupled to tube assembly 104 through welding. However, any connection method may be used in place of welding.
In a preferred embodiment, tube assembly 104 has a total length of ˜81″, an inner circumference of ˜0.8″, and an outer circumference of ˜1.09″. Slot 202 preferably has a length of 14″ and a width of ˜0.25″, with a first end of slot 202 starting ˜3.25″ from an end of tube assembly 104.
Compression spring 402, which is internal to tube assembly 102, is compressed by rod assembly 104 and provides force which maintains adjustable showing beam 100 in a fully expanded configuration unless a compression force is applied. In a preferred embodiment, one end of the spring is coupled to a stopper within tube assembly 102, preventing that end of the spring from moving and allowing a compression or stretching force to be applied to the spring.
Securement plate 702 further comprises cutout 802 which is used when joining securement hook 704. Cutout 802 is preferably arranged along a top of securement plate 702 at the center. Cutout 802 is preferably ˜0.55″ in width and ˜0.75″ in height.
Shoring beams of a similar nature are commonly available within the industry to span trailer walls to secure freight. However, these existing beams only allow for securement between mating E-track features in two parallel planes which are perpendicular to the length of the beam. However, the shape of securement hook 704 allows adjustable shoring beam 100 to be used between mating E-Track features which are (a) perpendicular to a length of adjustable shoring beam 100 or (b) parallel to the length of the adjustable shoring beam 100, such as the floor of a movable platform.
This embodiment does not include slot 202, screw hole 302, or screw 404. Further, first hook assembly 106 is detachably coupled to sliding rod assembly 102 and second hook assembly 108 is detachable coupled to tube assembly 104 as will be described later.
In the embodiment described in
As should be obvious, the diameter of rod assembly 102 is less than that of tube assembly 104 so that rod assembly 102 can slide within tube assembly 104. In order to accommodate the differing diameters, fixing clamp 1102 has a construction in which a first side has an inner diameter that is smaller than that of a second side.
First arcuate member 1804 is rotatable with respect to clamp body 1802 about first hinge 1820. First hinge 1820 is formed by a pin placed through first hinge section 1822 of first arcuate member 1804 and into body hinge section 1824 of clamp body 1802.
Second arcuate member 1808 is rotatable with respect to clamp body 1802 about second hinge 1826. Second hinge 1826 is formed by a pin placed through second hinge section 1828 and into body hinge section 1824. In some embodiments, a single pin may be used and inserted through first hinge section 1822, body hinge section 1824, and second hinge section 1828 simultaneously.
First latch member 1812 comprises first latch body 1834 and first latch extension 1836. A pin is placed through clamp body 1802, through first latch body 1834, and into second body hinge section 1832 so that first latch member 1812 is rotatable with respect to clamp body 1802 about first latch hinge 1832.
Second latch member 1814 comprises second latch body 1838 and second clamp extension 1840. A pin is placed through clamp body 1802, through second latch body 1838, and into second body hinge section 1832 so that second latch member 1812 is rotatable with respect to clamp body 1802 about second latch hinge 1842.
Similarly, a pin is placed through opening 2004 in first latch arm 1844 and first arcuate projection 1848. A first end of the pin terminates at first latch extension 1836 and a second end of the pin terminates before second arcuate member 1850.
First latch extension 1836 has a channel 2008 which aligns with channel 2006 in first latch arm 1842 and channel 2010 in second latch arm 1842. A pin is placed through channel 2006, channel 2008, and channel 2010. A first end of the pin terminates at an end of channel 2006 and a second end of the pin terminates at an end of channel 2010. The pin rotatably couples first handle 1806 to first latch member 1812.
Similarly, a pin is placed through opening 2204 in second latch arm 1856 and second arcuate projection 1852. A first end of the pin terminates at second latch extension 1840.
Second latch extension 1840 has a channel 2208 which aligns with channel 2206 in second latch arm 1854 and channel 2210 in second latch arm 1856. A pin is placed through channel 2206, channel 2208, and channel 2210. A first end of the pin terminates at an end of channel 2206 and a second end of the pin terminates at an end of channel 2210. The pin rotatably couples second handle 1810 to second latch member 1814.
As shown in
Lifting second handle 1810 allows clamp body 1802 and second arcuate member 1808 to rotate relative to each other about second hinge 1826. The rotation is limited through the coupling of second latch member 1814 to clamp body 1802 and second handle 1810 to second arcuate member 1808. By opening and closing second handle 1810, the tube assembly 104 can be moved and then locked in position.
The first curvature is preferably the same or slightly smaller than that of rod assembly 102 so that rod assembly 102 can be gripped by fixing clamp 1102 when first handle 1806 is in the closed position. Arcuate ribs 2402 may be covered with a friction surface such as a rough plastic or metal. The covering of arcuate ribs 2402 may also comprise a compressible material to accommodate a range of sizes of rod assembly 102.
The second curvature is preferably the same or slightly smaller than that of tube assembly 104, but still greater than the first curvature. This allows arcuate ribs 2408 to grip tube assembly 104 when second handle 1810 is in the closed position and depicted in
The area between arcuate ribs 2404 and arcuate ribs 2408 is preferably recessed, smoothed, and curved. This allows clamp body 1802 to have reduced weight.
Clamp arm 2410, clamp arm 2412, and second body hinge section 1830 all have channels for the aforementioned described pins. In some embodiments, a single pin is inserted into clamp arm 2410, first latch body 1834, second body hinge section 1830, second latch body 1838, and clamp arm 2412. Similarly, a single long pin can be inserted through second hinge section 1828, body hinge section 1824, and first hinge section 1822 to simultaneously form first hinge 1820 and second hinge 1826 as already described.
First arcuate member 1804 comprises at least two arcuate ribs 2602 having the first curvature. Arcuate ribs 2602 in combination with arcuate ribs 2408 form opening 1816 of fixing clamp 1102.
Second arcuate member 1810 comprises at least two arcuate ribs 2604 having the second curvature. Arcuate ribs 2604 in combination with arcuate ribs 2404 form opening 1818. It should be apparent to one of ordinary skill in the art that the number of ribs for arcuate ribs 2404, 2408, 2602, and 2604 may be increased if required or needed.
Turning next to
Connection clamp 2804 is depicted in
Further, in the depicted embodiment, there is a receiving structure 3404 only on a first side of bracket 2802. However, receiving structure 3404 can be added to any location around the exterior of bracket body 3402. In other embodiments, two or more receiving structures 3404 may be present on bracket 2802, such as on opposing sides (e.g., top and bottom, left and right). In another embodiment, four receiving structures 3404 are present around bracket 2802 which are positioned at a top, bottom, left side, and right side of bracket 2802. Different types of receiving structures 3404 may be coupled to different sides of the same bracket 2802.
Openings 3408 preferably have a diameter the same as or greater than a diameter of tube assembly 104 and/or rod assembly 102 so that bracket 2802 can be positioned along an adjustable shoring beam 100 when tube assembly 104 or rod assembly 102 is placed through openings 3408. In a preferred embodiment, openings 3408 have a same diameter as openings 2912 of connection clamp 2804 as depicted in
Bracket body 3402 generally comprises end members 3406 having openings 3408, with end members 3406 being parallel to each other. Two or more rectangular connecting beams 3410 connect the first end member 3406 to the second end member 3406 to form bracket body 3402. In the depicted embodiment, three connecting beams 3410 are present at a top side, a left side, and a right side of bracket 2802. Receiving structure 3404 is coupled to an exterior surface of one or more of the connecting beams 3410. A spacing between at least to connecting beams 3410 around the periphery of end members 3406 must be large enough so that handle 2910 can be opened and closed as needed.
Preferably, connecting beams 3410 have a same length as that of receiving structure 3404. However, it should be apparent that connecting beams 3410 may be longer and/or shorter than receiving structure 3404.
Bracket body 3402 is sized so that connection clamp 2804 can be nested within bracket body 3402 with openings 2912 and 3408 in alignment as depicted in
The design of the adjustable shoring beams 100 discussed herein are designed so that gravity causes the perpendicular connection side of bracket 2802 to naturally fall and rotate downward, maintaining a low profile. The coupling between connection assembly 2800 and adjustable shoring beam 100 is able to maintain a positive connection during transit and exceeds trucking securement standards. Further, because the length of adjustable shoring beam 100 can be quickly adjusted and added to vertical posts or used to bride other adjustable shoring beams 100, there is time saving compared to using straps 4502. The handle 2910 of connection bracket 2804 can also easily be manipulated by a user's thumb, even with gloves on.
