Definitions

  • This invention relates to a releasable grip-and-hold device formed for gripping large boards individually, and holding the individual board during subsequent swinging/lifting, comprising a board supporting frame which is connected, rotational about an essentially horizontal axis, to the end of a pivoted boomwork of a preferably drivable board-handling apparatus, there being arranged along a transversal side edge of the supporting frame, hooks, hook-like means or similar, parallel to one another, helping to hold the board securely during the swinging/lifting thereof and placing in its mounting position, where the board is released from the grip-and-hold device of the supporting frame.
  • the grip-and-hold device can be used for the mounting of for example plaster boards.
  • the invention similarly relates to a method of releasing a grip-and-hold device of the kind in question from a large board, which has been brought into a mounting position, the supporting frame carrying small, pivoted supporting means on which the underside of the board is resting, when the supporting frame has been pivoted about said essentially horizontal axis from a position corresponding to the stacking position of the large board into a position at least approximately corresponding to the mounting position of the large board, all hooks being pivotal and spring-loaded.
  • the grip-and-hold device comprises a supporting and holding frame with holding means positioned peripherally, securing the rectangular board in position on the frame during the pivoting and the lifting, moving and handling, from the stack of boards (the boards can be stacked standing at a steep inclination, or lying on top of each other) into the mounting position of the board, in which the board is to be released from the frame as soon as it has been brought into an accurately adjusted mounting position and secured - at least temporarily - for subsequent completing mounting.
  • a releasable grip-and-hold device with the features of the preamble ob claim 1 is known.
  • An embodiment of the grip-and-hold device described in this document comprises four hooks in the form of over-center clamps which can be secured manually by the movement of a handle to their locked position, in which they grip about the adjacent board edge.
  • the device has a supporting structure for supporting the panel and telescoping sleeves for raising and lowering the panels.
  • the panel supporting structure has a pair of cylindrical tubes which are fixed in parallel to a top panel.
  • a pair of identical upright support panels are fixed to the outer ends of the tubular rods and a pair of elongated beams are fixed across the top of the upright support panels.
  • a pair of wire rods are pivotally mounted to the outer end of the elongated beams, respectively.
  • the wire rods have each spaced rod portions and a lateral rod portion connecting the spaced rod portions together at one end and a lateral rod portion is connecting the spaced rod portions together at the other end.
  • the lateral rod portions are held in place of the beams by plates having a channel portion which surrounds the lateral rod portion and provides a pivotal support for it.
  • Bolts pass through the plates into the beams and each one has coil springs compressed between the heads of the bolts and the plates and urge the channel portion against the lateral rod portions, to normally prevent the movement of the wire rods about their lateral rod portions.
  • the aim is to provide a grip-and-hold device for boards, whereby there is achieved, on the one hand, a secure holding of such boards individually during lifting, swinging movements and handling in general, and, on the other hand, a reliable release of the grip-and-hold device is ensured, once a board has been brought into its accurately adjusted mounting position.
  • Such a grip-and-hold device comprises, in a known manner, a supporting frame for the board.
  • a hook-shaped gripping/holding means At two or more straight, mutually parallel frame parts of the supporting frame, there is arranged at both free ends a hook-shaped gripping/holding means, said hooks pointing towards one another by their points in the position of use, the end portions of the parallel frame parts with a respective hook each - at least on one transversal side of the supporting frame, being pivotally arranged about an axis parallel with the pivot axis of the supporting frame, and being held in a swung up active gripping and holding position by spring means, which allow a down-pivoting for the release of a board from the grip-and-hold device at least at one of two opposite securely held board side edges, the board then actually being released from the grip-and-hold device, which only needs to be moved in a direction away from the rear hooks in order to bring their gripping of the adjacent transversal board edge to an end.
  • the end portions of the hook-carrying frame parts of the supporting frame are all pivoted and can be returned resiliently into their active position, which facilitates the gripping of a board from a stack, and also release of the board in its fixed mounting position, but this pivotability at both transversal sides of the supporting frame is not critical for the implementation of the principal function of the invention.
  • the pivoted, hook-carrying end portions which are influenced by springs, and which are located at one transversal side of the supporting frame, can with advantage be provided with a controlling and deflecting means for the respective pivoted end portion.
  • This means may in an advantageous embodiment have the form of a curved element resembling a blade spring, secured to the hook-carrying, pivoted end portion of the frame part and curving downwards (convexly in the upward direction) when the respective hook is in a position directed upwards (for example in the mounting position of the board).
  • the supporting frame can be provided with small supporting means, which are also upright when the grip-and-hold hooks are in a position oriented upwards, and which may have an upward convex supporting surface, on which the surface of the board underside is resting during the different board-handling operations.
  • These small supporting means may pivot/tilt in a limited manner, when the board is about to be brought into the accurately adjusted mounting position, and their curved supporting surfaces are gentle to the board and facilitates the release of the board from the gripping device in the board mounting position.
  • each hook By a board thickness of about 13 millimetres the dimension of each hook, parallel to the edge surface of the board, may be about 15 millimetres, and the point portion of the hook may have a freely ending finger-like extension of about 1.5 millimetres, forming an (obtuse) angle with the surface of the primary hook.
  • the primary hook surface extends approximately perpendicular from a linear end portion of a frame part incorporated in the supporting frame, the hook being formed on the outer free end of the frame part, which has an upper edge surface and a lower one parallel thereto.
  • the outer end of said lower edge surface and the upper end of the hook surface are connected to each other by a curved transition edge surface, curved convexly in a direction away from the pivot point of said hook-carrying end portion of said frame part.
  • the small finger-like extension hook may extend in all events approximately tangential to said convexly curved transitional edge surface.
  • the so-called secondary extension hook must be of a very insignificant extent relative to the effective extent of the primary hook, which depends on the thickness of the relevant board dimension.
  • each pivoted hook-carrying end portion of the supporting frame has a spring arranged thereto, which works among other things as a return spring, which allows the hook-carrying end portion to pivot down when a ceiling board is released form the grip-and-hold device according to the invention, when the board has been brought into its mounting position.
  • the respective spring pulls the respective pivoted end portion somewhat upwards into a slightly inclined position, in which the hook is somewhat higher up than the pivot point of the end portion.
  • Such a position favours the grip-and-hold capacity of the combined hook (the primary hook with the secondary hook) straight opposite the adjacent board edge portion.
  • a board-lifting and handling device comprising a carriage 10 with driving wheels 12, a boomwork post 14 mounted upright on the carriage 10, carrying at the top a telescopically extendable/retractable boom 18 pivotable about a horizontal pivot axis 16.
  • a piston-and-cylinder 24 which initiates the pivoting motion of the boom 18 about the pivot axis 16.
  • a joint 30 with a horizontal axis, placed centrally relative to the supporting frame 26, ensures the pivotability of the supporting frame 26 relative to the boom 18.
  • the supporting frame 26 is provided with a grip-and-hold device according to the invention, in which there are incorporated grip-and-hold hooks 32 pointing towards one another.
  • Two or more parallel hooks 32 can be arranged on each of the transversal side edges of the supporting frame 26, the side edge of the supporting frame 32 appearing from most figures, being considered as one of the two longitudinal sides of the supporting frame 26, because they extend parallel to the boom 18.
  • each hook 32 is formed at the end of an end portion 34 or an end section of a longitudinal frame part, the supporting frame conceivably being configured in a known manner with mutually connected longitudinal and transversal frame parts, located essentially in the same plane.
  • each end portion 34 of at least one transversal edge is pivotally connected about a horizontal axis 36 to the associated frame part of the supporting frame.
  • the hooks 32 located to the right may be rigidly connected to the associated frame part, but a more flexible supporting frame is provided, in particular for the gripping and securely holding of a board, when all grip-and-hold hooks 32 are pivotally arranged in the manner shown.
  • a return spring 38 is arranged for each end section 34 with a hook 32. This return spring in the form of a tension spring allows the end section 34 with the hook 32 to be swung down with the hook 32 leading, when the board is to be released from the grip-and-hold device.
  • Each hook point can be extended by a short finger 40, which can have an orientation, see Fig. 7, whereby its longitudinal direction extends approximately tangential to a curved end surface 32a of the hook-carrying end section 34 of the supporting frame 26, which is pivotally supported at the end of the boom 18 about said horizontal axis 30.
  • the hook-carrying end sections 34 by one (the left-hand) transversal side edge of the supporting frame 26, are each provided with a controlling and motion-deflecting element 42 for the pivoted hook-carrying end section 34, in order to initiate the pivoting motion of the end section 34, when the free farthest projecting end/end portion of the motion-deflecting, controlling element contacts for example a vertical wall surface 44, Figs. 5 - 7, and cooperate therewith during the continued linear advancing of the supporting frame 26 with the board 28.
  • a controlling and motion-deflecting element 42 for the pivoted hook-carrying end section 34, in order to initiate the pivoting motion of the end section 34, when the free farthest projecting end/end portion of the motion-deflecting, controlling element contacts for example a vertical wall surface 44, Figs. 5 - 7, and cooperate therewith during the continued linear advancing of the supporting frame 26 with the board 28.
  • the supporting frame 26 also carries four or more (two are visible in the side views according to the figures in the drawings) small pivoted supporting means 44, whose individual pivot points 46 are parallel with the pivot point 30 of the supporting frame 26.
  • each of the small pivoted/tiltable supporting means 44 has a supporting surface 44a curved convexly upwards for a board 28.
  • a ceiling and a vertical wall immediately adjacent thereto are identified by 48 and 50, respectively, whereas the floor in the same room is identified by 52, Fig. 3.
  • the controlling and motion-deflecting element 42 may with advantage have a rounded, for example hook-shaped, end 42a, which helps to enhance the deflecting power of the element 42.
  • the rounding at the end of the controlling and motion-deflecting element thereby ensures that on abutment against a wall 50 or another vertical surface/edge, the element is brought into end-section-controlling, downward pivoting, displacing motion along said surface/edge.
  • the element 42 is resilient and flexible.
  • the hook-point-extending finger 40 may have the same properties, especially by the pivoting down of the hook-carrying end section 34 by the mounting of the carried/handled board 28 into abutment against the free transversal side edge surface 28b of a board 28a already mounted, Fig. 8, wherein the curved hook end surface 32a, ending in the hook point, in combination with the resilient, flexible hook-point-extending finger 40, in a controlling cooperation with the board edge surface 28b, initiates a sufficient down-pivoting of the hook-carrying end section 34 about the pivot axis 36, in order to release the leading edge 28c of the board 28 handled from the hook 32 with the securing finger 40.
  • the grip-and-hold device of the carriage frame 26 picks up a board 28 from a stack of horizontal boards lying on top of each other, Figs. 1 and 2. In this position the carriage frame 26 is rotated 180° about the axis 30 relative to the board-supporting position according to Figs. 3 - 9.
  • a very elongate, flexible rope-like element for example in the form of a wire.
  • This rope-like wire element and its effect in combination with the pivoting motion of the boomwork 18, will be explained in further detail later.
  • the length and points of attachment of the wire are adjusted so relative to the pivoting motion of the boomwork 18, that the supporting frame 26 with one large board 28 is rotated approximately 180°.
  • the board thickness may for example be 13 millimetres, and it then comes natural to choose a hook height of about 15 millimetres and a hook-point-extending finger length of 1.5 millimetres. By these hook dimensions relative to an estimated board thickness, a secure grip about a board 28 is ensured.
  • Fig. 4 shows the board 28 in a position, in which it is essentially in its mounting position, i.e. in the position where the board 28 should desirably be released from the grip-and-hold device, i.e. from the hooks 34, which are pivoted and spring-loaded at both transversal edges of the supporting frame 26 in Fig. 4.
  • the position sloping slightly downwards in the longitudinal direction (from left to right), in the direction towards the board-handling apparatus 10,14, is established after the supporting frame with the board was first positioned in a horizontal position, in which the board 28 was resting on the small pivoted supporting means 44, which then had positions directed perpendicularly to the plane of the supporting frame/board.
  • Said motion component effective in the plane of the large board 28 initiates an extraction of the left-hand edge portion of the large board 28 from the hook portions 32,40, said beginning extracting movement at the left-hand transversal edge of the supporting frame 26 providing at the same time a pressure effect in the plane of the board 28, directed towards the hooks 34 at the right-hand transversal edge of the supporting frame.
  • the pivoted resilient hooks 34 at the right-hand transversal edge will thereby swing down by their outer free hook portions 32, 40.
  • This down-swinging of the right-hand hooks allows the downward sloping displacement of the board 28 towards the right, so that the left-hand edge portion of the board 28 is pulled completely out of the adjacent hooks 34, whereby the board 28 is actually completely released from the grip-and-hold device according to the invention.
  • Figs. 4 - 7 is illustrated how the controlling and motion-deflecting element 42,42a causes a down-pivoting of the respective hook-carrying, spring-loaded end section 34 by utilization of the abutment and possibility of gliding displacement of the controlling and motion-deflecting element 42,42a down along the side wall 50, Figs. 6 and 7, the curved hook end surface 32a also participating in the gliding displacement.
  • the board 28 When a board 28 together with the supporting frame 26 has been rotated 180°, the board 28 has reached a supported position, in which it rests on at least four restrictedly pivoted/tiltable small supporting means 44 with supporting surfaces 44a curved convexly upwards and individual pivot axes 46 on the supporting frame 26.
  • Such supporting means 44 each having a horizontal pivot axis, represent supporting elements, from which the boards 28 can easily be released in its mounting position after the board has been released from the pivoted hook-carrying end sections.
  • the hooks 32 at one transversal edge of the supporting frame can be pivoted downwards.
  • the hook-carrying end sections 34 at the left-hand transversal side edge of the supporting frame 26 individually be downwards pivotable about a horizontal axis 36, and have returning, up-swinging tension springs 38 arranged thereto, and by preferably providing each of them with a controlling and motion-deflecting resilient element 42 with a rounded outer edge and preferably with a hook-point-extending flexible finger 40.
  • the right-hand hook-carrying end sections 34 of the supporting frame 26 may be rigidly connected to the rest of the frame 26 because a supported board 28 carried, which is released from the left-hand hook devices 32,34,36,38 of the grip-and-hold device, is practically released already from the gripping device.
  • a supported board 28 carried which is released from the left-hand hook devices 32,34,36,38 of the grip-and-hold device, is practically released already from the gripping device.
  • Each of the ends of the individual tension springs 38 is secured to an attachment lug 56 on the supporting frame 26, and to an attachment lug 58 on the pivoted hook-carrying end section 34 thereof.
  • wire 62 which has a first fixed attachment point 60 on the supporting frame 26 and a second fixed attachment point 66 on the post-like constructional element 14 of the board-handling apparatus 10,14, at the top of which, the boomwork 18 is pivotally arranged.
  • the horizontal pivot axis 30 of the supporting frame 26 is established through a pin secured to the end of the boomwork and rotationally supported between two bearing lugs 68 which may have the form of a segment of a cord/groove wheel, by which the wire 62 is guided until it has entered the cavity of the square tube forming the boomwork 18.
  • the wire 62 guide disks, not shown, can be arranged, and in the area of said second fixed attachment point 66 for the wire 62, the wire 62 has a tension spring or gas spring 64 arranged thereto, which is to resist tearing of the wire 62 by an incorrect pivot angle of the frame 26.
  • the length of the wire 62 and the choice of attachment points, are based on construction and/or experience.
  • the supporting frame 26 with the board 28 (from the stack of boards in Fig. 1) will be forcedly rotated, first into the horizontal intermediate position below the ceiling 48, and then into a position of release, sloping slightly downwards, Fig. 4.
  • the releasing of the board 28 from the grip-and-hold device of the supporting frame 26 has been described above.
