    BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a screw device for screwing boards to underlying crossbars in such a way that the screws are screwed inwards from the edges of the boards.
    Boards on underlying crossbeams are used e.g. to terraces. Between the boards there will usually be a gap.
    The screws can be screwed in using an ordinary hand operated screwdriver. But it is a slow and cumbersome process, especially when it comes to a larger number of boards. Over time, therefore, screwdrivers have been developed which are motor-driven and arranged to incrementally convey a disposable belt with detachable screws. This results in considerable relief from the previous work of manually rotating an ordinary screwdriver and holding a screw in position during the ice-crunching process, as well as the work being done much faster.
    A screwdriver of this kind is known from US Pat. 5,699,704 Bl. This known screwdriver is held manually in position during operation. This means that the particular angle that the screws need to form with the edges of the boards in order to achieve the required strength of, for example, a terrace, is not practicable. In addition, the work can only be performed from one edge of a board at a time.
    The deficiencies of the prior art thus are remedied according to the invention by providing, in a first aspect of the invention, a screw device of the type mentioned in the preamble with which the operator will effortlessly be able to screw boards onto underlying beams with screws which each forms precisely the particular angle with an edge of a board necessary to obtain the required strength of e.g. a terrace, in another aspect according to the invention, to provide a screw device of the kind mentioned above, with which the operator will be able to screw boards onto underlying beams without extra effort and time, in a third aspect according to the invention providing a screw device of the type mentioned initially, by which the operator can fasten boards much more quickly than previously known on underlying beams, in a fourth aspect of the invention to provide a screw device of the type mentioned initially, with which boards can be screwed onto underlying beams without leaving visible screw heads, in a fifth aspect of the invention, there is provided a screw device of the type mentioned earlier, which is more ergonomic to work with than known screw devices.
    These and further aspects are achieved according to the invention in that the screw device according to the invention comprises a base formed with an elongated foot in use on the upper side of the boards, two arms projecting obliquely from each end of the foot, and two opposite screwdrivers , which are mounted on each arm, each of which is arranged with means for advancing a disposable belt with detachable screws and for gradually tightening screws from the belt.
    This combination of features means that, for example, the components of a terrace can be screwed together faster than before, and that the terrace achieves optimal strength.
    According to the invention, the foot may consist of a left and a right foot section separated by a gap, as well as by an element such as a bolt extending across the gap and connecting the two foot sections. In addition, the member may have a left portion which is adjustable axially with the left portion slidably disposed in the left foot portion and a right portion slidably disposed in the right foot portion so that the foot can be adjusted longitudinally and thereby adapted to different designs with different width widths and thus varying distances between the spaces and the boards. An example of such a construction is a terrace, but the invention is applicable to any construction where a plurality of side-by-side elongated workpieces are to be screwed into an underlying second workpiece arranged at right angles to the longitudinal article, or several spaced apart from each other. underlying topics.
    The above adaptation can advantageously be achieved in a preferred embodiment according to the invention by forming in the right foot section a chamber such as that of the element, e.g. the right-hand portion of the bolt extends into a head which abuts against the right end wall of the chamber, while a compression spring extends between the head of the bolt and the left end wall of the chamber, while at the left foot section there is provided a longitudinal bore which extends the left-hand side of the bolt. fit in, allowing the foot to adjust easily, quickly and securely to fit varying widths of width and spacing between boards. The left foot section is thus arranged to clamp the left part of the bolt firmly in a selected position in the bore. In addition, on the underside of each of the two foot sections of the foot, a transverse rib may be arranged to effectively fix the position of the screw device in use.
    Advantageously, the undersides of the foot sections may thus be formed with separate transverse ribs having a height equal to or lower than the thickness of a board and a width equal to or narrower than the width of the gap between two boards, and the distance between the insides of the two foot section ribs corresponds to the width of a board when the foot sections are pulled sufficiently far apart to overcome the compressive force of the compression spring in the right foot section and the left part of the bolt is clamped in the preselected position in the left foot section bore.
    According to the invention, a rod may be attached to the side of the left part of the foot a little above the underside, with e.g. a foot, to be loaded in such a way that the distance between the ribs is increased sufficiently to be able to completely or partially eliminate the pressure exerted by the ribs against the edges of the board and which the pressure spring generates. The screw device is then easily and effortlessly pulled out of the spaces between the boards so that it is ready to use for the next operation. In any case, the upper portion of each of the base arms may conveniently be divided into two pieces of a slot of equal or greater width than the diameter of a screw, and a bore of the same or greater diameter than the head of the screw may extend through the slot and at least partially through the ribs to guide the screw in place.
    The screws of the screw device, which are relatively long, are normally designed with a right-hand thread to screw the screws in. In accordance with the invention, the screws can also be provided with an upper left-hand thread for successively removing the chips that form when a screw is screwed in. essential advantage is that the chips do not pack around the screw, making it more or less difficult to screw in the screw.
    The invention will be explained in more detail below with further advantageous features and technical effects, and advantageous embodiments are described with reference to the accompanying drawings, in which
    FIG. 1 is a side elevational view of the base according to the invention;
    FIG. 2 is a bottom view of the inventive base;
    FIG. 3 is a side view of the base of the invention fitted with two opposite screwdrivers; and
    FIG. 4 shows a screw according to the invention on a larger scale.
    In the following, it is believed that the screw device 30 according to the invention is used to screw it in FIG. 3 together with terrace 1. The terrace consists of a number of boards 2, which are screwed onto a number of underlying cross beams 3. However, the screw device can be used to assemble other types of similar structures, such as plank floors, rice floors, garden tables, etc., and use in connection with a terrace is given by example alone. Collecting smaller items of juxtaposed boards across sideways is another option. Terraces are regularly found outdoors in places where they are exposed to rain and changing temperatures. The boards 2 are therefore e.g. spaced at intervals 4.
    The screw device 30 according to the invention serves to quickly and easily screw the boards 2 onto the cross beams 3 with e.g. FIG. 4, which are screwed in at an angle from the edges 5 of the boards 2 with respect to a certain angle V, which each screw must form with the respective edge 5 to ensure the required strength of the finished terrace 1.
    These advantages are obtained by the base 7, which in FIG. 1 is a side view in longitudinal section and FIG. 2 from below. Specifically, the base 7 consists of an elongated foot 8 and two arms 9 which project obliquely from each end of the foot 8 at the same angle V with the foot which the legs are to form with the edges 5 of the boards.
    FIG. 3 shows that the foot 8 in use is on the upper side of the boards 2 and that two opposing screwdrivers 10 are mounted on each arm 9. The function and interaction of the screwdrivers 10 with the base 7 will be explained later.
    The foot 8 is composed of a left and right foot section 11,12 separated by a gap 13, as well as a bolt 14 extending across the gap and connecting the two foot sections 11,12. The bolt 14 may have a round or polygonal cross-section. In this case, the cross section is square.
    The bolt 14 has a left portion 15 slidably disposed in the left foot portion 11 and a right portion 16 slidably disposed in the right foot portion 12. The left portion may be locked in a selected position in the left foot portion, while the position of the right portion in the right foot portion is determined. compression spring 17 spring force. In the right foot section 12, a chamber 18 is formed which the right part 16 of the bolt 14 extends with a head 19 which abuts against the right end wall 20 of the chamber 18, while the compression spring 17 extends between the head of the bolt 19 and the left end wall 21 of the chamber 18. In addition, in the left foot section 11 is provided a longitudinal bore 22 into which the left part 15 of the bolt extends. On the underside of each of the two foot sections 11,12 of the foot 8, a transverse rib 23 which is narrower than a space 4 is arranged. between two boards. The distance between the opposite sides of the two ribs is substantially equal to, or at first, slightly smaller than the width of a board 2.
    In addition, a protruding rod 24 is secured to one side of the left foot section 11 at a distance above the underside of the foot 8. The purpose of this rod 24 will be explained later.
    As shown in FIG. 2, each of the arms 9 of the base 7 is divided into two halves 25 by a slot 26 of equal or slightly greater width than the diameter of a screw 6. The slot 26 also appears in FIG. 1 as the portion of arm 9 which is not shaded.
    A bore 27 having the same or slightly larger diameter than a screw head extends, as shown in FIG. 1, through the arm 9, the slot 26 and at least partly through the rib 23.
    The bore 27, like the arm 9, is divided into two halves of the slot 26 and forms the same angle V with the foot 8 as the arms 9 form with the foot. Due to the presence of the slot 26, a screw 6 can be pivoted laterally into the bore 27, which then controls the screw 6 while screwing into the edge 5 of a board 2 below the angle V.
    Since the screw has a smaller diameter than its head and thus of the bore, it will tend to rotate towards the underside of the bore around its head, so that it becomes more or less cumbersome to screw a screw into the edge of a board and the required angle V with the edge cannot be safely adhered to.
    Therefore, at the bottom of the bore, a support 28 is provided for holding a screw in place during the screw-in operation. In FIG. 3, the screw device 30 stands on the terrace 1 with the ribs 23 down in the spaces 4 on the sides of a board 2. The inside of the ribs, under the influence of the compression spring 17, abuts against the edges of the board 5 with one substantially corresponding to the spring force of the compression spring. The screw device is ready for use.
    The operation takes place by activating two prior art screwdrivers 10, facing each other on each arm 9.
    Each of these screwdrivers 10 comprises a drill 29 disposed on an upper housing 31 slidably disposed between an upper and lower position on a lower housing 32 which is again secured to one of the arms 9 of the foot 8.
    The upper housing 31 is mounted with a guide 33 for a disposable belt 34 with removable screws 6. The lower housing 32 also has a device (not shown) for progressively advancing the disposable belt. The belt 34 is then inserted in an arc into the lower housing 32 via a slot (not shown) which constitutes a continuation of the embodiment shown in FIG. 1 and 2, slot 26 shown in the arm 9. Said slots allow an upper part of the screw 6 to be pivoted into the lower housing 32 simultaneously with the passage of the belt, and a lower part is simultaneously pivoted into the bore 27 of the arm 9 in this way. previously described with reference to FIG. 1. The blank disposable tape 34 is extended on the opposite side. When the disposable belt has put a screw in the screw-in position, the feed is stopped, after which the operator (not shown) can screw the screw 6 into the edge 5 of a board 2 by means of the drill 29 and its spindle (not shown). In the housings 31 and 32 there is a compression spring (not shown) for pushing the upper housing 31 into its upper position when the screw device 30 is not used. When a screw is to be screwed in, the operator, while overcoming the spring force from the compression springs of the housings, manually pushes the upper housing down towards its lower position, while the drill screws the screw into the bottom.
    Finally, the operator allows the compression spring to push the upper housing back into its upper position so that the screw device 30 is ready for a new screw-in operation.
    As can be seen, the screw device according to the invention screws in two screws at once, and is twice as many as the known screwdrivers are capable of. The work of assembling a terrace with screws can therefore be carried out twice as fast as is known in the prior art when the screw device according to the invention is used.
    Another important advantage is that the screw device according to the invention automatically ensures that the screws always form the angle V with the edges of the boards which are necessary to obtain the required strength of the finished terrace. A further advantage is that two screws are always placed opposite each other.
    Above, it is assumed that the inside of the ribs abut the edges of the board. However, each board does not have exactly the same width in the longitudinal direction, and the different boards also do not all have the exact same width. In addition, the boards can easily lie more or less skewed when laid. Therefore, the screw device according to the invention can unscrew screws in a terrace where the width of the spaces between the boards varies.
    This is achieved according to the invention by locking the left part 15 of the bolt 14 into the longitudinal bore 22 in the left foot section 11 in a position where the distance between the inside of the ribs 23 is slightly smaller - e.g. some mm - than the width of a board 2, and then subtract the two foot sections 11,12 from each other while overcoming the spring force of the spring 17 until the ribs 23 drop into the two spaces 5 found at each board 2.
    Now the ribs are tightened in their spaces under the influence of the spring force 17 which effectively ensures that they do not jump out of the spaces during work, so that the screws would be screwed in incorrectly. In return, it will be difficult to pull the ribs out of the spaces, each time to change to new operation.
    However, this problem is solved by means of the one shown in FIG. 2, which is attached a distance above the underside of the foot 8 on one side of the left foot section 11. When stepped on this rod in a particular way, it acts as a pedal pulling the ribs in the opposite direction of the spring force, so that the ribs are no longer held in tension in the spaces.
    The screw device can then be lifted easily and effortlessly by the spaces so that it can be used for the next operation.
    The screws used are relatively long because they must first be able to reach through the board and then sufficiently far into the underlying cross beam to ensure that the terrace achieves the required strength. However, during the ice curvature of the wood of the terrace, chips are gradually formed, which eventually pack so much around the long screw that it is only difficult or not possible to screw further into the spindle of the drill.
    The screws 6 are therefore advantageously formed with a right-hand thread 35 at the bottom and a left-hand thread 36 at the top. The right-hand thread 35 serves to unscrew the screw and the left-hand thread 36 to successively remove the chips thus formed so that they do not wrap around the screw.
