Description

TITLE: Clamping device and method for hanging an air duct FIELD AND BACKGROUND OF THE INVENTION
The invention relates to a clamping device and a method for hanging an air duct.
Air ducts are conventionally hung from a structure of a building using threaded rods connected to brackets and supports. Hanging air ducts in this manner is time consuming, because many parts have to be fixed and adjustment is cumbersome.
It is also known to suspend air ducts using wire hangers. Wire hangers consist of a wire rope sling with an anchoring member, such as a loop, a threaded stud, a hook or an eyelet at one end. The size and position of the loop are adjustable and, once adjusted, the loop can be secured using a self-locking clamping device. Such a clamping device is disclosed in GB 2 415 012 (A) and comprises a first clamp for engaging the wire at one end of the loop for adjusting and fixing the position of the loop along the wire and a second clamp for engaging the wire at the other end of the loop for adjusting and securing the size of the loop.
However disadvantages of such wire hangers are that an inventory of wire length sizes and terminal types is needed of which a suitable terminal type and size has to be selected for the task at hand and/or that an excess length of wire is left after the wire has been installed, which excess length constitutes waste and has to be cut off if a neat appearance is desired and/or to reduce the risk of disturbing schaving and clattering noises.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a solution that allows hanging air ducts from a building structure in a quick and simple manner and which avoids the need of providing an inventory of length sizes and waste in the form of excess lengths of hanging material.
According to the invention, this object is achieved by providing a clamping device according to claim 1.
Because the clamping device is arranged to be mounted to a surface of a building structure and the clamping device has two clamps, each clamping one end portion of a flexible hanging member, an air duct can be hung from the building structure in a simple manner by mounting the clamping device to the building structure, providing a required length from a stock of hanging member material (for instance wire, rope or belt material), inserting the hanging member in one of the clamps, forming a loop of the hanging member by passing the other end of the hanging member from one side of the air duct underneath the air duct to the other side of the air duct and up to the other clamp where it is inserted and secured. Because both ends of the loop formed by the hanging member are secured in clamps, the material of the hanging member does not have to be provided with a terminal such as a loop or a fastener at one of its ends. Thus the required length of material of the hanging member may be cut off from a stock of material on site and installed without any further transformation. Accordingly, the need of keeping an inventory of hanging members of different lengths and with different terminals and/or waste of material by having to use hanging members of a larger length than necessary is avoided.
Because both end portions of the flexible hanging member are individually connected to the clamping device, the load of the air duct is transferred via the flexible hanging member via two end portions. Accordingly, the load is distributed over the two end portions, so the end portions are each loaded with about half of the total load. This, the flexible hanging member is loaded with only about half of the load with which a hanging member of which only one end is coupled to the building structure. Accordingly, when using a clamping device according to the invention, the hanging member can be of a relatively light and low cost type.
The length of the loop of the hanging member between the clamps may be adjusted at one of the clamps or at both clamps, for instance by pulling through a free end of the hanging member until the hanging member is taut. The required length of the hanging member material may be cut from the stock prior to insertion into the first one of the clamps, after insertion in the first one of the clamps but prior to insertion into the second one of the clamps or after insertion in both clamps, for instance depending on ease of reaching the clamps and the number of hanging members of identical lengths that have to be installed.
The invention can also be embodied in a method according to claim 9.
Particular elaborations and embodiments of the invention are set forth in the dependent claims.
Further features, effects and details of the invention appear from the detailed description and the drawings.

DETAILED DESCRIPTION
In the drawings, an example of a clamping device 1 according to the invention is shown. The clamping device 1 is for hanging an air duct 2 from a building structure 3 (see Fig. 5). The clamping device 1 has a housing 4 equipped with a first clamp 5 for clamping a first end portion 8 of a flexible hanging member 7 and with a second clamp 6 for clamping a second end portion 9 of the flexible hanging member 7.
The housing 4 has a mounting face 10 for mounting the clamping device 1 to a surface 11, including a passage 12 through the mounting face 10 for a shank 14 of a fastener 13 and an engagement surface 15 diametrically facing away from the mounting face 10 for engaging a head 16 of the fastener 13.
Hanging of an air duct using the clamping device 1 according to the present example can for instance be accomplished in the following manner. Apart from the clamping device 1, a flexible hanging member 7 (in the present example a belt) and a fastener 13 with a head 16 and a shank 14 are provided. The clamping device 1 is attached to the surface 11 of a building structure 3 by anchoring the fastener 13 in the building structure 3 with its shank 14 extending through the passage 12 in the housing 4 of the clamping device 1 and its head 16 engaging the engagement surface 15. The clamping device 1 is now secured to the building structure 3 in a fixed position so that it does not have to be held to allow operation of the clamps and/or insertion or adjustment of the hanging member 7. Accordingly, a worker installing the air duct has both hands free to handle the belt 7 and the air duct 2.
Next, an end portion 8 of the belt 7 is inserted into one of the clamps 5 of the clamping device 7 in the direction of arrow 17 as shown in Fig. 3, while the clamp 5 is held in an open condition. In the present example, this is accomplished by pressing a lever 18 connected to a clamping jaw 20 towards the surface 11 of the building structure 3 to which the clamping device 1 has been mounted against a biasing force exerted by a spring 22. In the open condition, the clamping jaw 20 is moved away from a counter surface 24 so that the end portion 8 of the belt 7 can easily be inserted in the space between the clamping jaw 20 and the counter surface 24. Because the worker installing the air duct 2 has both hands free, holding the clamp 5 in the open condition and simultaneously inserting the end portion 8 of the belt 7 can be carried out quickly and easily.
When, subsequently, the lever 18 is released, the clamping jaw 20 is urged back by the spring 22 to the clamping position shown in Fig. 4 in which the end portion 8 of the belt 7 is clamped between toothed surfaces of the clamping jaw 20 and the counter surface 24. The clamping jaw 20 is suspended so as to be pivotable about a shaft 26 such that pulling the end portion 8 of the belt 7 back in the direction of the arrow 28 in Figs. 4 and 5 causes the clamping jaw 20 to be entrained with a directional component towards the counter surface 24, so that the clamping force clamping the end portion 8 of the belt 7 between the toothed surfaces of the clamping jaw 20 and the counter surface 24 is increased. Accordingly, the end portion 8 of the belt 7 is reliably secured to the clamping device 1, by inserting it in the clamp 5 while holding the lever 18 in the open position and subsequently releasing the lever 18.
Next, the other one of the end portions 9 is passed underneath the air duct 2 (which is temporarily held in position, for instance by a temporary support or by a co-worker) from a side of the air duct 2 corresponding to the side of the clamping device 1 at which the clamp 5 to which the end 8 of the belt has been secured to the opposite side of the air duct 2 and, at the opposite side, upward to the other one of the clamps 6. Then, the other end portion 9 is inserted into the other clamp 6 in a manner corresponding to the insertion of the first end portion 8 into the claim 5. The lever 19 connected to the clamping jaw 21 is pushed toward the surface 11 so that an opening between the clamping jaw 21 and the counter surface 25 is formed, the other end portion 9 of the belt 7 is inserted into that opening and the lever 19 is released., so that the other end portion 9 of the belt 7 is clamped between the clamping jaw 21 and the counter surface 25. Thus, a situation as shown in Fig. 5 is reached in which both end portion 8 and 9 of the belt 7 project laterally outwardly from the clamping device 1.
The length of the belt 7 between the clamps 5, 6 can now easily be adjusted by adjusting the position at the belt 7 where it is clamped in at least one of the clamps 5,6. This can for instance be achieved by pulling one of the end portions 7, 8 or both through the corresponding clamp 5, 6 until the belt 7 is pulled taut and carries the air duct 2 in the desired position.
Both ends of the loop formed by the belt 7 are secured in the clamps 5,6. Accordingly, belts do not have to be provided with terminals such as a loop or a fastener at one of its ends and the required length of belt material can simply be cut off from a stock of material on site and installed without requiring any further transformation. Accordingly, the need of keeping an inventory of belts of different lengths and with different terminals and/or waste of material by having to use belts of a larger length than necessary is avoided.
Because the clamping jaws 20, 21 and the levers 18, 19 are arranged for moving the clamping jaws 20, 21 to the open position in response to movement of the respective levers 18, 19 towards a mounting plane 29 defined by the mounting face 10, operating the levers 18, 19 to bring the clamping jaws 20, 21 into the open position can be achieved in a simple manner by pushing the respective lever 18, 19 towards the surface 11 to which the clamping device 1 is mounted. This surface 11 will usually be a ceiling or other surface above the head of the worker, so it is advantageous that the levers 18, 19 can be operated by pushing from below, by hand or using a tool such as a stick or screw driver.
Furthermore, the levers 18, 19 project laterally out of the housing 4 in a direction away from the other clamp 6, 5. Projecting at the outside of the clamping device 1, the levers 18, 19 can be reached easily along the sides of an air duct 2 held approximately in a position where it is to be installed.
The clamping jaws 20, 21 and the levers 18, 19 are arranged between the counter surfaces 24, 25 and the mounting plane 29 and the levers 18, 19 are fixedly connected to the clamping jaws 20, 21. Thus, a simple construction allowing the clamping jaws 20, 21 to be brought into the open position by pushing the levers 18, 19 towards the mounting plane 29 is achieved.. In particular, the need of inverting movement of the levers and associated friction is avoided. The combination of clamping jaws 20, 21 and levers 18, 19 can be manufactured particularly efficiently, because the levers 18, 19 and the associated clamping jaws 20, 21 each form an integral part.
In the present example, the clamping device 1 has two clamps 5, 6 that each have a clamping jaw 20, 21 movable between a clamping position and an open position and a lever 18, 19 for urging the clamping jaw 20, 21 to the open position by pressing the lever to the mounting plane 29. Thus, both ends of the belt 7 can be secured and adjusted equally easily and during installation, insertion of the belt 7 into the clamps 5, 6 can be carried out in an order that is most convenient, taking into account the ease with which the levers 18, 19 can be reached in the mounting situation at hand. Also the adjustment can be carried out at the side of the clamping device 1, where the end portion 8, 9 of the belt 7 projecting from the housing 4 can be reached most easily. It is however also conceivable to provide that for instance only one of the clamps has a lever, while the other clamp may for instance be provided in a pretensioned open position and with a trigger for causing the clamp to close by operating the trigger after an end portion of the belt has been inserted into the clamp.
Because the clamps 5, 6 are each arranged for retaining the belt 7 against displacement in an inward direction towards the other clamp, not only the levers 18, 19, but also the free ends of the end portions 8, 9 of the belt 7 project laterally outwardly of the clamping device in directions away from a mid plane of the clamping device 1 (see Fig. 5). This allows tensioning the portion of the belt 7 between the clamps 5, 6 by pulling one of the free ends or both free ends outwardly from a position or positions of the free ends where these can be reached easily past a side of the air duct 2. Instead of installing a belt 7 that has previously been cut to size, it is also possible to install the belt 7 by pulling belt material from a roll or other stock of belt material, installing it in a position passing underneath the air duct with one end or both ends in the clamps 5, 6 and subsequently cutting off the required length of belt material. Thus, the need of measuring belt material can be skipped.
The belt material may be provided in association with clamping devices for clamping that (type of) belt material, for instance as a kit, so that all material needed for hanging air ducts from a building structure are provided in combination. The belt material, clamping devices and fasteners may also be provided separately, for instance for replenishing when stock of any of these has gone low.
Within the framework of the present invention, many other examples than the example shown in the drawings are conceivable. For instance, the hanging member may for instance be formed of wire, rope, rod or strip material, instead of being made of belt material. The clamps may be of a different design, for instance in the form of V-clamps in which material is clamped by sliding into a gradually narrowing slit between opposite ridges. As observed, both clamps do not have to be of the same type. One of the clamps may for instance be arranged for clamping the hanging member prior to mounting of the clamping device to the building structure, the material being clamped as the fastener for fixing the clamping device to the building structure is tightened. Instead of forming a surface of the housing, for instance as in the example shown, the mounting surface, the opening therethrough and the engagement surface, may also be formed on another part of the clamping device, for instance on a mounting bracket or other mounting structure for holding the housing in position relative to the building structure to which the clamping device is mounted
It is also noted that the combination of features according to which at least one of the clamps has a clamping jaw movable away from an opposite counter surface, from a clamping position for clamping the first or second end portion of the flexible hanging member between the clamping jaw and the counter surface, to an open position for allowing movement of the first or second end portion of the flexible hanging member through an opening between the clamping jaw and the counter surface, in longitudinal direction of said end portion, the clamping jaw being biased to the clamping position and the clamp having a lever for urging the clamping jaw to the open position, the clamping jaw and the lever being arranged for moving the clamping jaw to the open position in response to movement of the lever towards a mounting plane defined by said mounting face, is also advantageous if the clamping device has only one clamp and the hanging member has one end connected to the clamping device in another manner, for instance via a loop or a hook.
Several features have been described as part of the same or separate embodiments. However, it will be appreciated that the scope of the invention also includes embodiments having combinations of all or some of these features other than the specific combinations of features embodied in the examples.
