Definitions

  • This invention relates to a door dressing tool.
  • Doors are often found to jam, or at least become difficult to move, due to contact between the bottom of the door and a floor or floor covering over which the door swings.
  • a carpenter is called in to remove material from the bottom of the door. This may involve removing the door at its hinges, finding or providing a suitable surface on which to support the door, sawing a strip from the bottom of the door, planing it flat, sanding and then re-hanging the door.
  • the door and its hinges will also require repainting to make good any resulting damage to the painted surfaces. All this is very time consuming, inconvenient and costly.
  • the present invention seeks to provide a new and inventive tool which can be used to remove material from and dress doors whilst they are still hung on their hinges.
  • the present invention proposes a door dressing tool which is characterised by an elongate flat blade having an abrasive surface, and a support member at one end of the blade for supporting said end in use such that when the tool is placed on a horizontal floor the support member holds one end of the blade above the floor, the tool incorporating resilient means such that when a door is swung on its hinges to move over the blade the blade exerts a continuous upward pressure on the bottom of the door.
  • the resilient means is preferably provided by forming the blade of a springy material, such that the portion of the blade in contact with the door tends to adopt a generally horizontal attitude whilst still maintaining an upward pressure.
  • Different grades of abrasive may be provided on carrier strips secured to the blade by a pressure-sensitive adhesive or similar releasable means.
  • a coarse abrasive may be used for removing material from the door while a fine abrasive can be used to achieve a smooth finish once the required amount of material has been removed.
  • FIG. 1 is a general view of a door dressing tool in accordance with the invention.
  • Figure 2 is a plan view of the tool
  • Figure 3 is a side view of the tool, showing the tool in use
  • FIG. 4 is a detailed section through the blade portion of the tool.
  • Figure 5 is a general view illustrating the main use of the tool.
  • the tool includes a blade 1 and a support member 2.
  • the blade 1 is generally about 500 mm long by 50 mm wide and is formed of a flat elongate strip of springy metal, similar to a paint spatula.
  • An upper surface of the blade carries a strip of abrasive material 3.
  • the blade has a rounded end 10 while the opposite end, shown in outline in Fig.s 2 and 3, is formed with a flattened tang 11 having an enlarged tip 12.
  • the support member 2 is preferably formed of a solid polyethylene, polypropylene or similar strong low-cost thermoplastic which is moulded about the tang 11.
  • the support member is of elongate shape, having shallow longitudinally arcuate top and bottom surfaces 20 and 21 each terminating in straight edges 22 and 23 which lie on a plane extending substantially parallel to the blade 1.
  • the sides of the support member, 26 and 27, are also of shallow longitudinally arcuate shape.
  • the abrasive layer 3 is formed of hard particles 30 bonded to the upper surface of a flexible carrier strip 31 of strong paper, cloth, plastics sheet or similar material.
  • the lower surface of the carrier layer 31 has a layer of pressure-sensitive adhesive 32 which, prior to attachment to the blade 1 , is protected by a peelable backing layer 33.
  • the user is provided with a choice of strips, some having relatively small abrasive particles (preferably between 80 and 200 grit) while other strips have relatively a relatively coarse abrasive (preferably less than 60 grit). After removing the backing layer 33 the adhesive is used to bond the required strip to the blade 1.
  • the adhesive layer 32 has a high shear strength such that the carrier layer remains firmly secured to the blade when an abraded surface moves across the abrasive layer. However, the adhesive has a low tensile strength enabling the carrier layer 31 to be peeled from the blade to replace the abrasive layer.
  • the tool is inserted into any gap which can be found along the bottom of the door, as shown in Fig. 5. Normally there is such a gap, but if not, it is possible to start working at the outer edge of the door.
  • the tool is supported on the floor F, either directly on a floor surface or on top of a carpet or other floor covering.
  • the user places his/her foot S on the tool as shown. Since the blade is thin, a door D to be dressed can be moved over the abrasive surface of the blade.
  • the support member 2 raises one end of the blade 1 above the floor surface but the door causes distortion of the blade as shown in Fig. 3.
  • the abrasive removes material from the bottom of the door.
  • the inherent springiness of the blade causes the blade to curve downwardly so that it maintains an upward pressure on the bottom of the door and, in addition, the portion of the blade in contact with the door is depressed towards a position in which it is approximately parallel with the floor.
  • the tool When the required amount of material has been removed from the door the tool can be moved along the door to remove further material which might be causing the door to bind.
  • the fine-grade abrasive any rough surfaces can be smoothed in the same manner.
  • a fine-grade abrasive can be applied to one surface of the blade and a coarse abrasive may be applied to the opposite surface so that the tool can be used for coarse or fine dressing simply by turning it over.
  • the shape of the support member 2 also allows the tool to be used as a powerful hand sander with the support member held as a handle.
  • the tool is not limited to removing material from doors, although it is particularly adapted for this purpose. It will be appreciated that the features disclosed herein may be present in any feasible combination. Whilst the above description lays emphasis on those areas which, in combination, are believed to be new, protection is claimed for any inventive combination of the features disclosed herein.

Abstract

L'invention concerne un outil de dressage pour portes comportant une lame plate allongée (1) pourvue de particules abrasives (3), fixée sur une bande support (31) qui est collée à la lame au moyen d'un adhésif sensible à la pression (32). Un élément support moulé (2) se trouve à une extrémité de la lame de manière à soutenir ladite extrémité lors de l'utilisation, de telle manière que lorsque l'outil est placé sur un sol, l'élément support tient une extrémité de la lame au-dessus du sol. La lame est constituée d'une matière élastique, ainsi lorsqu'on fait pivoter une porte sur ses charnières pour la déplacer sur ladite lame, la lame exerce une pression continue vers le haut sur la partie inférieure de la porte afin d'abraser la matière de la porte. La bande support peut être enlevée par pelage de la lame, et des bandes présentant différents niveaux d'abrasion peuvent être fournies.
