Definitions

  • the present invention relates generally to a carriage and, more particularly, to a wheeled carriage for transporting, fitting and installing a construction panel.
  • Construction panels such as the types of panels which are mounted as doors or plate glass windows, generally are quite heavy and awkward to handle, particularly during the fitting and installation stages of a construction process.
  • a variety of devices have been proposed for facilitating panel handling operations. Such devices typically provide some type of rolling base upon which the weight of a substantially planar, relatively heavy panel is supported and rolled to the desired point of installation. The panel then is manually removed from the base and mounted in the desired orientation.
  • Hansen has a door- carrying frame mounted on a wheeled base. A door panel rests on the frame and is supported alternately in either a reclined travel position or an upright installation position forward of the base.
  • the shortcomings of Hansen are illustrative of the prior art and should be understood.
  • Hansen suspends the center of mass of a panel carried on the frame forwardly of the base when the frame is upright, the Hansen device has limited stability when used in an installation mode of operation whereby the entire apparatus has a tendency to tip.
  • the instability is particularly evident when attempting to move the device such as when moving a door panel toward a door jamb. This is because the weight of the panel and frame is cantilevered ahead of the wheels and the device consequently requires operator effort to prevent overturning of the base.
  • Hansen fails to provide means for mechanically adjusting and maintaining the position of a panel carried on the frame when the frame is in position for installation of the panel. That is, the Hansen device is incapable of variably elevating or rotating a door panel when the frame is upright.
  • the present invention overcomes the above disadvantages by providing a wheeled base and an articulated frame on the base for supporting a construction panel in a multitude of operator- defined orientations during transportation, fitting and installation of the panel.
  • the frame and a construction panel secured to the frame are movable relative to the base between (a) a reclined transport position in which the center of mass of the construction panel overlies the area bounded by the wheels of the base to enhance stability of the carriage during transportation of the panel, and (b) an upright installation position in which the center of mass of the construction panel is located forwardly of the wheels of the base.
  • roller bearings or transfer balls below the frame transfer a portion of the weight of a construction panel secured to the frame to the surface on which the carriage operates.
  • the weight of the panel is supported forwardly of the base to enhance stability and facilitate omnidirectional rolling movement of the carriage.
  • the transfer balls are arranged in a row and can be spaced less than about five centimeters from the line of action of the weight force of a construction panel secured to the frame when the frame is in an upright position.
  • Independently operable elevators are provided on the frame for uniformly elevating the base and the frame and a construction panel secured to the frame while maintaining contact between the transfer balls and the operating surface.
  • the elevators are operable differentially for adjusting the roll angular orientation of the base and the frame and a construction panel secured to the frame.
  • a telescoping arm on the base is provided for adjusting the pitch angular orientation of the frame relative to the base when a construction panel secured to the frame is in an upright position.
  • the carriage has an overturned working position in which a construction panel secured to the frame rests on the floor along a side edge thereof.
  • a laterally extendable strut on the base supports a portion of the weight of the carriage when the carriage is overturned.
  • a plurality of manually operated position control mechanisms retain the fitted position of a construction panel relative to the base so that the panel can be quickly and precisely returned to the fitted position after being worked in the overturned condition of the carriage.
  • welded steel structure of the carriage and frame as described taken separately or collectively, may be constructed of cast joints and tubing, metal or plastic (thereby requiring little or no welding) , or stamped metal parts.
  • the described stability is substantially independent of human leverage and so facilitates hands-free operation by a craftsman.
  • a further object of the invention is to provide a carriage capable of moving omnidirectionally during transportation, fitting, and installation of a construction panel.
  • the present invention is uniquely adapted to provide such a benefit, even when a construction panel secured to the carriage is held in a substantially vertical orientation.
  • a further object of the invention is to provide a carriage having the capability of positioning a construction panel secured to the carriage about three translational degrees of freedom and three rotational degrees of freedom.
  • a further object of the invention is to provide a carriage usable for installing a construction panel and the like whereby once the panel is initially placed on the carriage and secured by the craftsman, the panel need not be removed from the carriage until it is installed in final position.
  • a feature of the invention is the ability of the carriage to function alternatively as a transport means and as a work bench for operating on a panel secured to the carriage, such as for marking or trimming a door panel secured to the carriage, without removing the panel from the carriage.
  • Yet another objective of the invention is to ensure repeatability of positioning of a panel secured to the carriage. After a construction panel is appropriately fitted to a mounting location, the carriage and construction panel are moved away from the mounting location and the panel is prepared for installation, such as by attaching hinges to a door panel. Once prepared for installation, the carriage and panel subsequently are returned to the substantially exact same position as when the panel was fitted.

  • the carriage 10 is configured for fitting and installing the construction panel in a doorway.
  • the carriage 10 is uniquely adapted to support a construction panel in a multitude of operator-defined orientations to facilitate transportation, fitting and installation of the panel during a construction process.
  • the carriage 10 further is suited to carry a variety of construction materials, such as generally planar panels made of window glass or wall board, and no interpretation of the following is intended to suggest or imply that use of carriage 10 is limited to applications involving doors.
  • the carriage 10 has a base 16 and an articulated frame 18 mounted on the base 16 for carrying a construction panel 12.

  • the upper end of the intermediate shaft 134 is further supported within side rail 66 by a rail bushing 150.
  • the lower end of the intermediate shaft 134 is coupled to a reduced-diameter upper end 135 of the drive shaft 130 with a cylindrical pin connector 152.
  • Upper end 135 of the drive shaft is further supported within side rail 66 by a shaft bushing 154 seated in a spacer 156 and by a shaft thrust bearing 158.
  • the elevator located within side rail 68 has a manual elevator control knob 160 for actuating a drive mechanism that is in all 12 respects substantially identical to the elevator described above with regard to the side rail 66.
  • the transfer ball or roller bearing means 118 and the elevators interconnected between the articulated frame 18 and the transfer bar 124 provide a number of important advantages as follows:
  • the fact that the load bearing function achieved by the bearings 122 accommodates rolling contact further enhances operation of the carriage 10. That is, in addition to providing improved static support and stability of the carriage, the roller bearings 122 provide supplemental stabilizing support while permitting the loaded carriage to be easily rolled forward, rearward, and laterally in an upright position. This feature is particularly useful when controlling fine adjustment of a relatively heavy, upright object into an installation position.
  • the control knobs 138 and 160 are independently operable.
  • This feature permits synchronous or, in the alternative, differential extension of the associated elevators contained on the frame 18 for elevating the base 16, the frame 18, and a panel 12 secured to the frame. 13
  • the control knobs 138 and 160 are manually operated so that the input shaft 136, the intermediate shaft 134, and the drive shaft 130 uniformly rotate within each corresponding one of the side rails 66 and 68.
  • the drive shaft 130 is fixed axially within each rail so that rotation of the input shaft 136 causes the corresponding elevator nut 132 and the output member 128 to travel axially relative to the lower end of the drive shaft 130.
  • Uniform extension and retraction of the output members 128 thereby results in lifting, and alternatively lowering, of the articulated frame and base.
  • the roller bearings 122 remain in contact with the operating floor surface while the construction panel is lifted. They also maintain a stable, rolling support for the carriage 10 when the frame and base are elevated in a uniform mode of operation of the elevators.
  • the control knobs 138 and 160 and associated drive mechanisms also have a differential mode of operation in which the elevator contained in the side rail 66 is extended to a different length than the elevator contained in the side rail 68. As shown in Figure 11, this may occur while a simultaneous unitary roll displacement of the base and frame is achieved relative to the operating floor surface. Differential operation of the elevators thus results in rotation of a construction panel 12 within the substantially vertical plane defined by the panel when the frame and panel are in the upright, installation position. Similar to the uniform lifting mode of operation described above, the roller bearings 122 remain in contact with the operating floor surface 120 even while the carriage is moved during fitting and installation of a construction panel 12.
  • the carriage 10 is also adapted for use as a work bench and has an overturned working position (Figure 15) in which a construction panel 12 , secured to the frame 18 , rests in a substantially horizontal orientation on a side edge 170. This orientation is helpful in relation to routing and attachment of hinges to a door panel edge. In Figure 15, this is shown as upper edge 172. 14
  • the carriage is overturned toward one side with the A-frame 38 spaced above the operating floor surface 120 and beneath A-frame 36.
  • a telescoping strut 174 is located within cross rail 24 of the base and is extended prior to overturning the carriage. In this way, the strut 174 will provide an offset support means for holding the panel in a side edge working position.
  • a similar opposing strut 176 is located within the opposite end of cross rail 24. It is extended axially from the opposite end of the rail when it is desired to overturn the carriage opposite to the direction shown in Figure 15.
  • a set screw 178 (one shown in Figure 1) is provided at each end of the cross rail 24 and extends through respective corresponding portions of support member 20, 23.
  • the set screws retain the struts 174 and 176 within rail 24 during upright use of the carriage.
  • the set screws also lock the struts at a desired extension when the carriage 10 is used in the work bench mode of operation.
  • the present invention provides a superior level of stability when moving an upright construction panel in any combination of three translational and three rotational independent degrees of freedom.
  • the roller bearings 122 uniquely support the weight of a construction panel on the ground or a floor surface forward of base 16. This feature overcomes the tipping tendency of previous cantilevered frame designs.
  • Use of the twin-elevator lifting mechanism results in lifting of the entire carriage from the ground (rather than merely lifting the frame from the carriage) and maintains contact between the roller bearings and the ground, thereby enhancing steadiness of the carriage when a construction panel is elevated.
  • the degree to which a construction panel can be controllably positioned ensures a proper fit and installation. Elevation, tipping, and rolling of the panel are precisely controlled by independent drive mechanisms located within the holdback arm 62 and the frame side rails 66 and 68. 15
  • Controlled positioning of the frame relative to the base permits the carriage and a construction panel to be moved away from a mounting location for additional working of the panel. And, the panel can be subsequently returned to the exact mounting location since fine adjustment of the panel is retained by the various described drive mechanisms. Repeatability of fitting is thereby facilitated and the construction process is expedited.
  • the base of the carriage could have a generally Z-shaped side view in which the skewed rails 42 of the A-frames are omitted and the dimensions and material of the remaining structural members are selected to provide acceptable strength in the overall carriage.
