Definitions

  • Outdoor furniture such as is used in barbecue and pool areas is sometimes made of foldable construction so as to be stowable for seasonal reasons. Work benches are sometimes made to fold flat in order to be hung on a wall when not required. True knock down furniture, where the components form a stack of separate parts is rare.
  • Picnic tables tend to be of solid construction with a table top stapled to a pair of A-frames. A pair of narrow elongated seats are fixed to the A-frames alongside the table. Such tables are seldom moved, never taken to a picnic in a vehicle and generally weather to a silver colour where they stand.
  • This invention provides a knock down item of furniture comprising a tie member which in the assembled item, constitutes the main useable surface, a pair of ground- engaging supports, a tie abutment for each support which defines the working positions of the supports, a removable key capable upon insertion between the tie member and each support, of forcing the supports against the abutments, rendering the structure rigid, and upon key removal allowing disassembly of the components.
  • the item may be a table, work bench or the like.
  • the supports may be of sheet material with parallel or tapered upright sides but more usually the supports will be of inverted U-shape or A-frames made of 75x50, 100x50 or 100x25 timber stock.
  • the supports may bear one or more additional tie members at a lower level than the main useable surface, such as seats, each with an abutment against which the supports are clampable by one or more removable keys.
  • the effectiveness of the keys can be improved if a spine is fixed to the underside of the main tie member, creating in effect an extension of the reaction surface provided by the main tie member.
  • the slope of the extension may be 1-3 degrees more than the taper of the key so that the key tightens on insertion and remains tightest at the edge of the spine furthest from the main tie member.
  • the slope of the extension may be 105-110 degrees to the plane of the tie member.
  • Another aspect of the invention provides an outdoor table with twin attached seats wherein the conventional diagonal bracing between the A-frames and the underside of the table is replaced by a a pair of keys which lock the supports against abutments on the table and secondly the abutments on the seats.
  • This same principle is applicable to space frames, e.g scaffolding, furniture, small buildings made of stiles and rails, poles, sheet material such as fibreboard, laminates and composites; metal components such as tube, extrusions, sheet metal sections and angle iron; plastic components such as tube and expanded bead sheets.

  • Fig 1 is a section through a picnic table showing the reaction surfaces; a fragment of seat is shown in broken lines to indicate the housing and Fig 2 is an end view of the picnic table of Fig 1 with the table and seats removed in order to show the abutments and grooved horizontal parts;
  • Fig 3 is a plan of the underside of a seat showing the position of the stored wedges.
  • Fig 4 is a diagramatic fragmentary section of another version wherein the wage is inserted parallel to the support frame
  • Fig 5 is a perspective of a timber connector used in the construction of the support frames.
  • the table top 2 is made from 100x25 pine boards surrounded by 50x25 lipping 4. A pair of
  • rectangular slots 6 (only one shown) are situated on the longitudinal central axis of the table top .
  • a spine batten 8 with inclined end 10 is fixed to the underside of the table and extends between the two slots 6 as shown.
  • the end 10 is inclined at 100 degrees to the plane of the table.
  • the boards are stabilised by a pair of battens 12 which are rebated to provide a tongue 14 the purpose of which will be described later.
  • the table top 2 is borne by a pair of A- frames made of inclined 100x40 legs 16, a stretcher 18 and a header 20.
  • the header 20 has a groove 22 which receives tongue 14.
  • the stretcher 18 has a 5 groove 24 at each end to assist the location of the seats 26 .
  • Each seat is made of 100x25 pine boards surrounded by lipping 4 and linked by pairs of battens 12.
  • Each batten and stretcher have a tongue and grooved formation as seen in the header.
  • the battens 12 have a tongue 14 which is accessible through notches 28.
  • Stretcher 18 has end grooves 24 which are engaged by tongues 14. The seats slide in and out on assembly and disassembly. Wedges 30 are retained by a cleat.
  • the structure is stiffened by a pair of long wooden wedges 30 whose slope is about as shown, is inserted through slot 6 in the table. Driving the wedge downwards traps the A- frame between the reaction surfaces.
  • the table is dismantled by tapping the wedges upwardly using a shoe heel
  • the tongues are able to tilt sideways out of the grooves and all the parts disengage.
  • Pads of hook and pile fasteners permit the seats to adhere to the table so they can be carried as a unit by means of a rope carrying handle while the A-frames stack easily. This facility
  • a sheet steel timber connector 34 has a pair of upturned teeth 36 and a pair of down turned teeth 38.
  • a single bolt 40 suffices to fix the angular dispositions of the connected parts. I have found the advantages of the above embodiment to be:
  • the components will fit in a car boot, caravan, trailer or on a roof rack.

Abstract

Table pour pique-niques démontable dotée d'une paire de sièges et d'un dessus de table porté par une paire de cadres. Les cadres sont serrés contre une paire de butées par une paire de clavettes. Tout gauchissement oblique est empêché par une barrette fixée à la face inférieure du dessus de table. Une paire de sièges sont également portés par les cadres, et les clavettes s'étendent de la face supérieure du dessus de table jusqu'aux sièges de manière à bloquer les cadres contre les butées prévues sur les sièges. On peut démonter la table et les sièges et obtenir un ensemble peu encombrant que l'on peut transporter dans le coffre d'une voiture de tourisme. Les clavettes assurent une rigidité élevée même lorsque les sièges sont fortement chargés.
