Abstract: A support arm arrangement for a local gas extractor arrangement and a local gas extractor arrangement including such a support arm arrangement. The support arm arrangement includes a first support arm and at least one second support arm being pivotally coupled to each other by friction joint arrangements. The support arm arrangement receives a tube device coupled to an extractor hood, an exterior pump device and the support arms. The extractor hood is arranged at an outermost second support arm by a linkage arm arrangement including a first link arm pivotally coupled to the outermost second support arm by a first friction joint pivotable about a first pivoting axis, and a second link arm fixedly attached to the extractor hood and pivotally coupled to the first link arm by a second friction joint pivotable about a second pivoting axis extending in a direction perpendicular to the first pivoting axis.

Abstract: A fastening device configured to be mounted to an elongated profile element of a support arm arrangement, and a method of mounting said fastening device to a support arm arrangement. The support arm arrangement exhibits a cross-sectional profile shape, and the fastening device is configured to hold a tubing member by means of a holding element, configured to be coupled to the fastening device and to the tubing member. The fastening device includes a contour surface at least partly corresponding with said cross-sectional profile shape, wherein the contour surface is configured for engaging and retaining the fastening device to the elongated profile element when the fastening device is mounted to the elongated profile element.

Abstract: This invention concerns an arrangement 1 intended to be used in a ventilation arrangement in order to hold and control an air channel 2. The arrangement 1 comprises a single arm construction 1.1 that is arranged along the outer surface 2A of the air channel. The arm construction 1.1 comprises two arm sections 3 and 4 arranged one after the other, a first joint 5 that unites a first arm part 3 with a fixture arrangement 6 that holds and maintains the basic position of the arm construction 1.1 and that makes possible different positioning, bending and stretching, of the arm construction 1.1 and the air channel 2, a second joint 7 that unites the first arm section 3 with the second arm section 4 and that makes possible different positioning, bending and stretching, of the arm construction 1.1 and the air channel 2. Each arm section 3 and 4 comprises an extended aluminum profile 8 and 9. The invention concerns also a ventilation arrangement comprising such an arrangement 1.

Abstract: This invention concerns an arrangement (3) that is comprised as a component (4.2) of an airtransport channel where the air-transport channel component (4.2) comprises two tubular sub-elements, a first sub-element (7) and a second sub-element (8), where the second element (8) has a diameter that is somewhat larger than that of the first element (7), which allows the first element (7) to be inserted into the second element (8) such that the two elements (7, 8) can be displaced relative to each other in a telescopic manner.

Abstract: This invention concerns a joint construction 1 intended to be used between two extended tubes 2 and 3 in order to connect these tubes 2 and 3 with each other and where the joint construction 1 offers an open internal compartment 4 that, during use of the joint construction 1, is connected to the open inner compartments 5 and 6 of the relevant tube element. The joint construction 1 comprises a first joint half 7 and a second joint half 8 that are essentially identical, an arrangement 9 that holds the joint halves 7 and 8 and thus the joint construction 1 together and where the joint halves 7 and 8 each comprise a first part 12 and 13 and a second part 14 and 15. The first parts 12 and 13 make possible a connection of the relevant joint half 7 and 8 to one of the tubes 2 and 3.

Abstract: A lockable friction joint, in particular one intended to be set to a desired relative swing position between two sections of tube, whereby the friction joint comprises a first joint part with a first arm part or section of tube and a second joint part with a second arm part or section of tube. The first joint part and the second joint part each support a ring provided with a pusher dog. The friction joint comprises two friction disks provided with holes, each disk having means for transferring motion to the rings. A friction plate, provided with a hole, is arranged between the friction disks. The friction disks are coupled to transfer motion with the ring that is located on the opposite side of the friction plate, and the friction joint is compressed by adjustable tightening means.

Abstract: A rubber spring (7) for a vehicle axle leaf spring suspension comprises a rubber pillar (8) which at an upper end is attached to a tunnel shaped mounting member (20) having a tunnel (13) with interior upper and lower surfaces (21,22) and adapted to house an end portion of a spring leaf (6) of a leaf spring suspension. The upper and lower surfaces are convex so as to allow tilting of the rubber pillow relative to the spring leaf.

Abstract: The invention concerns a lockable friction joint, in particular one intended to be set to a desired relative swing position between two sections of tube, in, for example, a gas extraction arrangement, a point suction arrangement, or similar, whereby the friction joint (20;70) comprises a first joint part (21;21?) with a first arm part (22) or section of tube (22?) and a second joint part (23;23?) with a second arm part (24) or section of tube (24?). The first joint part (21;21?) and the second joint part (23;23?) each support a ring (25;25? and 26;26? respectively), which rings are provided with pusher dogs (27;27?). The friction joint (20;70) comprises two friction disks (30,31;30?,31?) provided with holes, each disk having means (32;32?) to interact in a manner that transfers motion to the rings (25,26;25?,26?) that are provided with pusher dogs. A friction plate (35;35?), provided with a hole, is arranged between the said friction disks (30,31;30?,31?).
