Description

A Portable Dispensing System For Roll Stored Materials.

This invention relates to improving the ease and effectiveness of unrolling or dispensing a range of roll stored materials in various working environments. There can be difficulty experienced in practical building situations due to access, available personnel, working area, working height and the like in unrolling sheet material to desired lengths and keeping them flat, smooth, tensioned and accurately positioned for final fixing. This invention can be adapted to a variety of situations and in a number of different ways .to address these difficulties This invention comprises a portable dispensing system for roll stored materials such as reflective foil laminates, plastic, shade cloth, fencing mesh, building paper and general purpose membranes, useable on site in various situations, comprising two opposing adjustable roller heads and a series of interchangeable purpose built mounting systems that enable the choice of positioning for the dispenser onto a stud wall, a post, a substantially horizontal flat surface, a roof frame a floor flame, and the like, or free standing, all in a "manner to enable the dispensing of the roll stored material at or adjacent to the finished point of installation of the product.

The roll stored material will have a hollow core formed by a void of the 20 material or a cardboard or plastic tube onto which the material has been wrapped. The roller heads of the invention are designed to fit into this hollow core, adjustable by sliding towards each other to engage the roll from both ends. The roller head consists off a flat disk with a central protrusion, such 0 •protrusion tapering symmetrically away from the plane of the flat disk and presenting a series of fins, ridges or bumps parallel to the line of taper for the purposes of accommodating various core diameters of material being dispensed ~and to adequately grip the material onto the dispensing system.

This invention can be fitted with a system which can facilitate tensioning of the roll stored material during the drawing out process of the material from the roll by operating a drag system which reduces the ease of turning of the roller. This feature will also prevent over dispensing from the roll by retarding any rotational momentum once the operator has ceased the drawing out action.

Typically this tensioning ability of the invention enables one person to unroll and fix into position the roll stored material as this material can be held both taut and immediately adjacent to the point of fixing by virtue of the invention securing one end of the roll stored material whilst the operator secures the opposite end.

The invention can also be fitted with a full braking system which will prevent any unrolling of the roll stored material.

Typically this invention would be used to position a roll of reflective foil laminate to a building stud frame. This invention is equally useful in unrolling roll stored material in other than a perpendicular plane. Other applications could include: plastic underlay of concrete slabs, roof sarking or reflective foil laminate for installation on roofs and over floor frames, shade cloth installation on horizontal or vertical planes, fencing mesh in a vertical plane, building paper and a range of waterproofing and or general purpose membranes and the like.

One application of this invention, the positioning of reflective foil laminates or the like to enable unrolling and fixing of such material to a building stud frame will now be looked at in detail.

O *a 20 FIG 9 shows one example of a portable dispensing system for roll stored material operating from a substantially flat surface.

FIG 10 shows one example of a measuring system for dispensed material.

FIG 11 and 12 show an example of a portable dispensing system for situating on a roof or floor frame.

Referring to Figure 1 it can be seen that the dispensing system consists of a length of material, in this case square section metal tube which constitutes the body of the system 1. Attached to the body by means of fitted sleeves 2&3 are two opposing and adjustable roller heads. Also attached by fitted sleeves are two adjustable interchangeable purpose built mounting systems. Details of the mounting system and the roller heads of this application will be described later by reference to FIG 2,3 and 4 respectively.

Referring to FIG 1 it can be seen that by engaging the stud 6 by the mounting systems the dispensing system will be accurately positioned immediately adjacent to the stud. A roll of roll stored material,7, typically in this case reflective foil laminate can then be positioned by placing the core of the roll onto the roller head protrusion 8, sliding down this protrusion until the core diameter of the reflective foil laminate roll engages the fins typical of 9. With S6 the reflective foil laminate held vertically, the second roller head can now slide down the body, 1, whereby the protrusion 10 can enter the core similar to the first roller head. The sliding action of fitted sleeves 2,3,4,&5 is allowed by virtue of the outer cross section dimension of body 1 being marginally smaller than the inner cross section dimension of the fitted sleeves. The sliding action can be halted at any determined position by means of the cranked 20 bolt 10,11,12 13 being screwed through the body of the fitted sleeve and engaging the surface of body 1 with a thrust pressure sufficient to firmly locate the fitted sleeve at that point. A similar fitted sleeve can be used on other optional components of the dispenser.

The reflective foil laminate can now be drawn out from the dispensing system 25 parallel to the stud wall to the desired length. By reference to figures 5,6,7 8 it can be seen that there is a choice of alignment of the dispensing system and •of the material being dispensed to the stud work. All choices are available by reportioning the fitted sleeve to the appropriate alignment.

The height of the dispensing system on stud 6 can be adjusted to ensure the reflective foil laminate unrolls at an appropriate height, typically with the lower edge of the reflective foil laminate aligning with the lower edge of the stud wall structure. Where the reflective foil laminate width requires two or more widths to cover the height of the stud wall then the entire dispensing system with reflective foil laminate attached can be lifted up to the next appropriated height and reattached to the stud. The drawing out procedure can then be repeated.

Where there are impediments to the appropriate positioning of the dispensing system against a stud, for example a wall brace or noggin, the mounting system can be repositioned along the body of the dispensing system by means of releasing the cranked bolt as appropriate and moving the fitted sleeve as appropriate.

A tensioned riding bar 15 can be positioned whereby sufficient pressure is applied to the surface of the roll stored material to prevent the material unfurling. This riding bar can be appropriately sized spring steel capable of maintaining position at right angles to the body 1 when in use or of lying parallel to the body 1 when not required. The riding bar may also be spring loaded to induce pressure against the material.

The purpose built mounting system as depicted in FIG. 1 is shown in greater detail in FIG 2 This mounting system allows the dispensing system to be attached to a timber stud. Essentially it consists of a pivoting action at 1 where the opposing protrusion 2 in the shape of a spike is placed behind stud 3 with the pivoting point 1 against the opposite face of the stud. Protrusion 2 will 00WVengage the surface of the stud when the dispensing system is drawn in the direction of 4. The dispensing system is moved down in the direction of consequently the engagement of 2 to the adjacent surface of the stud 3 is increased, enabling the weight of the dispensing system and roll stored material to be supported on the stud. The shape of protrusion 2 can also be modified to 0 0include a multiple series of spikes ,teeth or ridges.

00 The shape of protrusion 2 may also be modified to allow a surface of sufficient area, which can be roughened, patterned or otherwise worked to establish a frictional contact between its surface and the surface of the stud 3.Whilst these modified forms of protrusion 2 can be used to attached to a timber stud they can also be employed to attach to a metal stud. The frictional contact between "the engaging surfaces when applied to a metal stud can be increased by the •addition of a magnetic component to the mounting system.

o* 0 By reference to figure 4 the breaking assembly can be seen consisting of a pad 1 which is forced against the underside of the flat disk 2 by the upward action of boss 3 This upward action of 3 is derived in two ways. Firstly the lever 4 o.o operates a cam assembly on the surfaces 5 against 6. The lower section 5 can rotate being a sliding fit to the circular section of shaft 7. Shaft 7 cannot rotate as the shaft is a square sliding fit where it passes through a square hole 8 in arm 9 Boss 3 with cam surface 6 is a sliding fit to shaft 7 however is restrained from rotating by a sliding fit to the housing where arm 9 enters the body of boss 3.Thus operating the lever 4 in either direction will induce an opening action between 5 and 6. pressing pad 1 against disk 2. The reaction of disk 2 away from pad 1 is prevented by the nut assembly of 10 holding down the protrusion 11 being part of disk 2. Thus the rotary action of roller head can be prevented.

The second breaking action can provide a retarding of the rolling action to any determined extent by inducing a constant breaking action of selected force between pad 1 and disk 2 This is achieved by tightening the nut assembly 11 which compresses the components along the shaft 7 together, bring pad 1 and disk 2 together to an extent determined by the amount of thread taken up by nut assembly 11.At any point of this second breaking operation the operation of lever 4 will override the constant breaking action and fully break the rolling action of the roller head.

M

In Figure 9 on application of the invention can be seen where it is desired to draw off roll stored material in a generally horizontal plane. The invention can incorporate two interchangeable purpose built flat stands 1 2 that allow the invention to sit stably on a substantially flat surface.

By reference to Figure 10 it can be seen that a measuring system can be positioned whereby the material being dispensed is measured as it rolls off the dispensing system by means of a wheel, 1, which is spring loaded to hold it firmly against the material roll and mounted with its rotational axis parallel to the rotational axis of the dispensing system and which is connected mechanically or electronically to a counting system, 2. The wheel can be moved back away from the roll when so desired In Figure 11 and 12 an application of the invention can be seen where it is desired to install roll stored material typically reflective foil laminate onto a roof frame. Two interchangeable purpose built mounting systems shown in 15 Figure 12 can be used. The yoke 1 is adjustable by screwing threaded section 2 Sto tohe desired position. The lever operated cam 3 provides a quick action grip o and release mechanism. A slide fit of sleeve 4 over section 5 means there is a degree choice of alignment of yoke 1 to sliding fit 6 designed to accept the body of the dispensing system. The invention can then be positioned to dispense either parallel to or at right angles to the roof frame component the dispensing system is attached to.

0 The invention can, on a predominantly flat surface, be free standing vertically 0 •.using a single stand that utilises a vertically orientated slide fit of claim 15 over 00 the body of the dispenser. The stand can be a metal frame comprising three or 25 four legs of sufficient size and span to hold the invention stable during the dispensing operation.

"In one form the invention can be positioned vertically and adjacent to a round pole or post by utilising two interchangeable purpose built mounting systems similar to claim 6 but varying in as much as the opposing surfaces are concave to each other. They could also be magnetised to facilitate additional grip onto metal poles or post.

In one form the invention can incorporate an inbuilt cut off system that will cut the material being dispensed to the desired length. This cut off system could take the form of a captive blade passing along a guide over which the material being dispensed must pass.

In one form, an aspect of the invention, the interchangeable purpose built mounting systems, can be attached to purpose shaped metal bodies of similar material to the dispensing body. This can be utilised to support a material storage platform or lightweight mobile platform that can be attached to a stud wall.

In one form of the invention a purpose shaped metal body could employ the interchangeable purpose built mounting system to suspend from a stud wall and allow uprights which would be an extension of the metal body, to extend above the eave lines to form a perimeter roof safety railing system.
