Definitions

• This invention relates to portable, adjustable frames and in particular to frames for use in forming door and window openings during construction of a building.
• window and door openings are usually formed from lengths of timber, which are braced in the corners or across the centre in order to keep square.
• a large plank is then spiked and placed on top at an angle to the floor to form a strut for the frame. This enables the bricklayer to build around the frame, thereby forming the openings.
• a hammer or saw is used to free the timber, taking care not to disturb the recently laid brickwork.
• This present invention aims to ameliorate this problem.
• the present invention provides a frame comprising a pair of elongate primary members adapted to be maintained in variable, spaced- apart, substantially parallel relationship by means of a pair of elongate secondary members, in which each end of each said secondary member is in sliding engagement with a primary member so that, in use the two secondary members extend substantially diagonally relative to the two primary members, said secondary members crossing each other at a crossing-point intermediate said primary members, and said secondary members being pivolally secured to each other at said crossing point, whereby the resulting scissor-like movement of said secondary members brings about a variation of the distance apart of said primary members.
• the frame may include at least one foot member provided at at least one end of one or both primary members.
• the frame may include a foot member provided at each end of one or both primary members.
• Each said foot member may be adapted for pivotal movement.
• each foot member may be adapted to pivot through substantially 360°.
• each foot member may be adapted to pivot through substantially 270°.
• the frame may also comprise a brace member to engage the foot members on opposite primary members, to give additional rigidity to the frame.
• the frame may be manufactured from mild steel, stainless steel, aluminium, wood or from a plastics material.
• the frame may also comprise pegholes or notches on one or both primary members .
• the pegholes or notches fixedly locate a secondary member such that a desired width apart of the primary members can be maintained.
• the pegholes or notches may correspond to a distance in millimetres, centimetres or inches apart, these distances being indicated on one or both primary members .
• the ends of one or both secondary members may further include an indicator to show clearly the distance apart of the primary members.
• One or both primary members may also comprise one or more telescoping portions.
• the or, each telescoping portion may have locating means to fixedly locate the or each telescoping portion.
• the locating means may be a clip, a peghole or a notch.
• One or both secondary members may also comprise one or more telescoping portions.
• the or each telescoping portion may have locating means to fixedly locate the or each telescoping portion in position.
• the locating means may be a clip, a peghole or notch.
• FIGURE 1 is a perspective view of the frame in a closed condition
• FIGURE 2 is the frame of Figure 1 in an open condition, with a pivoting foot member
• FIGURE 3 is a front elevation of the frame of Figure 1;
• FIGURE 4 is a back elevation of the frame of Figure 1; and;
• FIGURE 5 shows the frame of Figure 1 in use.
• the frame 1 comprises a pair of elongate primary members 2, adapted to be maintained in variable spaced-apart parallel relationship by means of a pair of elongate secondary members 3.
• Each end of each secondary member 3 is located in sliding engagement with a primary member 2.
• the secondary members 3 cross each other at a crossing point 4, at which crossing point 4 the secondary members 3 are pivotally secured to each other.
• Foot members 5 are provided at the ends of the primary member 2.
• the foot members 5 are pivotally secured to the primary members 2.
• the foot member 5 is adapted to pivot through 360°.
• the foot members serve to locate the frame onto a surface e.g. the ground or existing brickwork (see Figure 5) .
• the primary members 2 have pegholes or notches 6 so as to locate the secondary members 3 in a fixed position and set a desired width of the primary members 2 and therefore the frame 1.
