[0045] A front wall tongue pathway 32052 can be defined in the front wall 32002 and can be in communication with the wedge void 32040. A portion of the bottom 32042 can define a bottom extent of the front wall tongue pathway 32052. The front wall tongue pathway 32052 can also be defined by a top 32054 (shown in
[0046] A pair of spring seating voids 32070 can be seen with specific reference to
[0047] An access void 32082 can be defined in the top 32006. In various aspects, the access void 32082 can be of various shapes and sizes. In the current aspect, the access void 32082 can be defined as circular in cross-section and being defined of a cylinder.
[0048] In various aspects, the wedge housing 320 can be of various materials, including various metals, plastics, polymers, and composites, includingbut not limited toductile iron, carbon steel, stainless steel, titanium, polyethylene, polycarbonate (PC), acrylonitrile butadiene styrene (ABS), PC/ABS, fiberglass, and various combinations thereof. One of skill in the art would understand that various materials not listed herein can be utilized as well.
[0049] The wedge 310 can be see with reference to
[0050] The wedge 310 can define a friction-inducing surface 31028 on the bottom 31008. The friction-inducing surface 31028 can be a variety of physical applications in various aspects of the current disclosure, including etching, diamond patterns, roughened surfaces, and various other methods known to those of skill in the art. In the current aspect, the friction-inducing surface 31028 can be a plurality of teeth 31032. In the current aspect, teeth 31032 defined in the bottom 31008 can be formed as extruded sections extending from one side wall 31012 to the other side wall 31014. In various aspects, the teeth 31032 can be intermittent; in various aspects, the teeth 31032 can contain gaps; in various aspects, the teeth 31032 can be angled such that individual teeth do not extend from one side wall 31012 to the other side wall 31014; in various aspects, the teeth 31032 can be spikes; in various aspects, the teeth 31032 can be tacks or nails; in various aspects, the teeth 31032 can be sharpened. One of skill in the art would understand that the friction-inducing surface 31028 can define a variety of shapes, methods, or applications known to those of skill in the art to achieve the desired frictional arrangement.
[0051] Another aspect of a wedge 310 can be seen with reference to
[0052] The spring 330 can be seen with reference to
[0053] Engagement of the clamp 5000 can be seen with reference to
[0054] As each tongue 250 slips in the tightening direction 900, other parts of the housing 100 as connected to the tongue attachment 200 can be pulled in the tightening direction 900 as well. Each stop end 185 can be pulled into contact with its respective stop wall 32028 by this action, thereby pulling the corresponding wedge housing 320 in the tightening direction 900 as well. Compressive forces on the gasket 600 can increase as a result of this action, thereby promoting sealing action of the gasket 600 against any piping element within the clamp 5000. As each wedge housing 320 gets pulled in the tightening direction 900, the corresponding wedge 310 can be biased or pushed in the opposite direction 910 by one or more of spring 330. The top 31006 of such wedge 310 can come into contact with top 32044 of the wedge void 32040 thereby forcing the wedge 310 in a radially inward direction 920. Such force can allow the teeth 31032 to be forced into the outer surface 255 of the tongue 250, causing the clamping assembly 300 to engage the tongue 250. The teeth 31032 can be biased against radial pullout in the opposite direction 910 such that the tongue 250 can be prevented from moving in the opposite direction 910 while simultaneously being allowed to move in the tightening direction 900. A radially outward direction 930 is also shown for reference.
[0055] As noted previously a tightening tool (not shown) can be used to achieve these results. It is noted that the clamp 5000 can omit traditional fasteners such as bolts, washers, nuts, and lugs. In doing so, the clamp 5000 can address a wide range of diameters of piping elements while also being of relatively low cost due to the omission of costly components. A single tightening tool can be used for multiple applications and multiple sizes of clamps 5000 such that the tool can be an element of the installation equipment. With removal of the costly fastening elements, the clamp 5000 can reduce costs by 15% over wide range clamps containing traditional fastening elements.
[0056] A modified housing 100 can be seen with reference to
[0057] A release tool 1100 can be seen in use with the clamp 5000 in
[0058] Another aspect of a clamp 6000 can be seen with reference to
[0059] In the current aspect, each tongue 6250 can comprise a tongue end 6265. Each tongue end 6265 can comprise an anchor 6270. The anchor 6270 can be an expanded feature of the tongue 6265 that can provide a location to connect a clamping tool 7000. The cam housing 6314 can also define an anchor location 6399. In the current aspect, the anchor location 6399 can be a protrusion or arm extending from the cam housing 6314. In various aspects, the anchor location 6399 can be a feature of the cam housing 6314 such as a dimple or concavity that can allow interaction with the clamping tool 7000.
[0060] The clamping tool 7000 of the current aspect can comprise electric or hydraulic actuation, among other potential methods of actuation. The clamping tool 7000 can comprise a main body 7100 and an anchor body 7200. The main body 7100 can comprise an anchor 7150 that can be designed to interact with the anchor location 6399. Similarly, the anchor body 7200 can comprise an anchor 7250 that can be designed to interact with the anchor 6270. The main body 7100 can be connected to the anchor body 7200 by an actuation shaft 7300. In various aspects, the actuation shaft 7300 can be made of metal or various other sufficiently rigid compositions to provide force between the main body 7100 and the anchor body 7200. In one aspect of the clamping tool 7000, the actuation shaft 7300 can be of magnetic material; the main body 7100 can comprise an electromagnetic actuator to force the actuation shaft 7300 away from the main body 7100. In such an arrangement, the anchor body 7200 can force the anchor 6265 in the tightening direction 6900, and the anchor 7150 can force the clamping assembly 6300 in the opposite direction 6910 such that a tightening force is applied to the clamp 6000.
[0061] In various aspects, the actuation shaft 7300 can be hydraulically actuated. In such aspects, the main body 7100 can comprise a hydraulic cylinder and additional apparatus known to one of skill in the art to be necessary for hydraulic force. In various aspects, the actuation shaft 7300 can be threaded. In such aspects, the main body 7100 can comprise an electric motor that can be turned to provide actuation force to the shaft 7300 to separate the anchor 6265 from the clamping assembly 6300 to provide clamping force in the manner described above. In various aspects, the electric motor can be a direct current (DC) motor; in various aspects, the electric motor can be an alternating current (AC) motor. In various aspects, the electric motor can be omitted in favor of a hand crank mechanism, operating similarly to an automotive jack.
[0062] Another aspect of a clamp 8000 can be seen with reference to
