Description
This invention relates to instruments or devices for placing graphic designs, ornamentation or decoration on walls or ceilings, and particularly to such instruments and devices including means for drawing or painting vertical and horizontal lines or arcs either pencil width or in the form of wider stripes or segments.
Background of the Invention
Reference may be made to the following U.S. Pat. Nos. of interest: 824,299; 3,081,545; 3,263,334; 3,817,178; and 2,555,741.
There is at present a persistent demand for providing the decoration or ornamentation of both walls or ceilings in new and existing structures using graphical designs consisting of painted arcs or vertical and horizontal and transverse line segments. Currently, such ornamentation is normally accomplished by either freehand painting the desired graphic design or by utilizing standard straight edges and a number of circular edges each of a different diameter.
Freehand drawing or decorating requires a considerable amount of artistic skill and steadiness in the decorator. In addition, in large wall or ceiling surfaces, it is very difficult and near impossible to maintain consistency in drawing line segments or arcs. On the other hand, while there exists or can be devised a number of drafting-type instruments for pencil or ink drawing of line segments and arcs, such as illustrated in the aforementioned U.S. Pat. Nos. 824,299; 3,081,545; and 3,263,334, they do not disclose or teach any means for painting, nor are they readily adapted for decorating large surfaces such as walls or ceilings with graphical designs. U.S. Pat. No. 3,817,178 is helpful in applying a specific repetitive pattern onto a wall or ceiling, however there are no means shown or suggested for placing vertical or horizontal line segments or arcs of the desired width onto such surfaces.
Summary of the Invention
Therefore, in accordance with the principles of the present invention, there is provided an instrument having a plurality of elongated sections each joined by a flexible unitary portion so that either a single section or an elongated member formed of the composite sections can be positioned to lay adjacent the wall or ceiling surfaces. Each section includes a series of spaced apertures extending substantially along the longitudinal center line of said sections and adapted to provide a pivot point at one end and means for receiving a marking device at the other end for drawing arcs of any desired radius on the wall or ceiling surface. Each elongated instrument section further includes a series of spaced apertures extending along the opposite longitudinal edges of each section. One aperture on each longitudinal edge forms paired edge apertures, the centers of each of which are aligned with one of the center-line apertures spaced along the section center line.
A paint pad with a bottom foam pad portion for painting arcs or vertical and horizontal segments includes a pair of pegs on the upper portion of the paint pad. The pegs can be inserted into one of the respective paired apertures on the instrument section to place the bottom foam pad portion adjacent the wall or ceiling surface. The paint pad can be detachably mounted at different paired edge apertures on the sections to provide concentric painted arcs in the graphical design. In addition, the paint pad diameter is dimensioned with respect to center distance between the center-line apertures so that the painted arcs will cover the outlined markings previously placed on the surface using the center-line apertures.
A roller guide is adapted to detachably mount at one end of the elongated instrument section and includes a pair of rollers for engaging the wall of ceiling surfaces and thereby maintaining equal distant spacing of the center-line and edge apertures with respect thereto. This permits vertical or horizontal lines or painted segments using the detachable paint pad to be graphically imprinted on the surfaces. A connecting or link member is also provided for joining together two elongated members where ornamentation is to be provided on very large surfaces. On rather small surfaces or in corners, the single elongated member can be bent at its flexible portion in order to draw small arcs or short line segments.

Detailed Description
Referring now to FIG. 1 there is illustrated an instrument 10 for placing graphic designs, ornamentation or decoration on walls or ceilings of a room. The instrument 10 includes a plurality of elongated sections such as 12, 14 and 16 interconnected by integral flexible portions 18 and 20.
As illustrated in the left-hand portion of FIG. 1, a pair of concentric outlined arc segments 22 have been placed on wall 24 by inserting a pin or other rigid device through center-line pivot aperture 26 at one end of the instrument and a pencil or other marking device through respective center-line apertures in instrument section 14. A painted arc segment 28 upon wall 24 is provided by attaching a paint pad to instrument section 16 as will be described hereinafter. In accordance with another aspect of the present invention, the right-hand portion of FIG. 1 illustrates two graphical design instruments 10 interconnected by means of a linking member 30 for providing the illustrated arcs on wall 32.
FIG. 2 illustrates another aspect of the present invention wherein the instrument 10 has been folded along flexible sections 18 and 20. This permits a paint pad attachable to the instrument section 12 as will be described hereinafter to place a circular painted section 34 about pivot point 26 on the respective wall 36 at a position closely adjacent the wall corner 38.
As shown in FIG. 3, one end of the graphic design instrument 10 includes the elongated, substantially rectangular sections 12 and 14 joined by a flexible portion 18. The instrument can be formed of a rigid plastic material so as to comprise the several substantially rectangular sections 12, 14 and 16 as shown in FIG. 1 formed integrally with portions 18 and 20 having material removed therefrom to form groove 40 on one side and smaller grooves 42, 44 on the other side, thereby enabling the portion 18 to be flexible. The techniques for forming the several hard plastic sections with the integral, flexible portions therebetween are well-known in the plastic art.
Each of the elongated instrument sections 12, 14 and 16 is provided with a series of center-line apertures 46 spaced equidistant along the longitudinal axis or center line 48. FIG. 3 illustrates the center to center distance as one inch, although more or less spacing can be provided as desired. A series of respectively paired edge apertures 50, 52 are also included on the longitudinal opposite edges of the instrument sections as shown in FIG. 3. Furthermore, as can clearly be seen from FIG. 3, the center of each respectively paired edge apertures 50 and 52 is aligned with one of the section center-line apertures 46. Also, it may be noted that the instrument sections 12, 14 and 16 further include dimensional indicia along one edge thereof aligned with the respective center-line apertures 46 and paired edge apertures 50 and 52. Thus, the outline markings 22 shown in FIG. 1 can be made by inserting a pin or other hold-down means through pivot point 26 located at the first center-line aperture 46, placing a pencil or other marking device through one or more of the other center-line apertures 46, and rotating the instrument 10 about the pivot point 26.
Referring now to FIGS. 5-7, there is illustrated the attachment of a paint pad 54 to instrument section 16 for providing a painted arc segment 28 onto wall 24 as illustrated in FIG. 1. Paint pad 54 includes a bottom foam pad 56 mounted to a rigid top plate 58.
Foam pad 56 is formed of a suitable soft, resilient material adapted for receiving paint and transferring the paint to a surface when placed in contact therewith. Various types of material are readily available for such use. A pair of cylindrical pegs 60 extend upwardly from plate 58 and are sized with respect to the paired edge apertures 50 and 52 so that the pegs can be inserted into a respective aperture for releasably mounting the paint pad to one of the instrument sections. Thus, as shown in FIG. 5, paint pad 54 is mounted to instrument section 16 at the paired edge apertures 50 and 52 aligned with the 36 inch indicia on section 16. As illustrated in the cross-sectional view of FIG. 6, foam pad 56 is adhesively bonded or otherwise secured to a thin disc 62, with the disc 62 in turn being bonded to the top plate 58. The diameter of top disc plate 58 is slightly larger than the width of instrument section 16. This can be seen from FIGS. 5 and 6. This is provided in order to enable the pad 54 to be readily attached and detached from the instrument sections by gripping the edge of plate 58 or disc 62 when attaching or detaching the paint pad.
It is understood, of course, that the pad 54 can be mounted with the upstanding lugs 60 engaging any of the paired edge apertures 50, 52 along the instrument. As an example, in FIG. 5, at the 34 inch marker, there is indicated in dashed lines a paint pad 54 after having been removed, for instance, from the 36 inch location. It may be noted that the diameter of the paint pad is slightly greater than two inches so as to provide a slight overlap at the 35 inch location thereby covering with paint any pencil or other marker lines that may have been previously placed at this location. In conjunction with the paint pad 54, there is also provided handle adapter 64 including a disc portion 66 having apertures 68 for engaging lugs 60. A handle 70 extends upwardly from the disc 66 for attaching the handle adapter to the paint pad and for use of the paint pad during graphical designing on the walls or ceilings.
FIGS. 8 and 9 illustrate apparatus in accordance with the principles of the present invention adapted for readily providing vertical and horizontal graphic segments on walls or ceilings. Guide member 72 includes a central, generally rectangular member 74 and two wing sections 76, 78 extending respectively from the central portion 74. Central section 74 includes four projecting lug members 80 each of which is dimensioned to fit within the guide member mounting apertures 82 located at the end of instrument section 12 as shown in FIG. 3. Each of the wing-like projecting sections 76, 78 has mounted on the end thereof an associated roller 84, 86 rotatably mounted to the wing sections by suitable support means such as axle 88, 90.
In using the roller guide member 72, the unit is placed as shown in FIG. 8 with the four lugs 80 inserted into the mounting apertures 82. It is understood, of course, that the lugs and apertures are dimensioned so that the guide member can be readily detachably engaged from the instrument section 12.
In FIG. 9, instrument 10 is shown with roller guide member 72 and with paint pad 54 mounted in position for providing horizontal painted segment 92 on wall 94. In particular, it may be noted that the rollers 84 and 86 rollingly engage ceiling 96 as instrument 10 is moved in the indicated arrow direction to place a horizontal stripe or painted segment 92 onto the surface 94. FIG. 9 also includes in the dashed line portion thereof placement of the instrument so that rollers 84 and 86 engage wall 98. Thus, in the dashed line portion, movement of the instrument 10 upwardly in the indicated arrow direction will provide a vertical stripe 100 onto wall 94. It is understood, of course, that painted stripes parallel to either the horizontal stripe 92 or the vertical stripe 100 are readily provided by detaching paint pad 54 from the indicated location and mounting the pad at one of the other locations on sections 12, 14 or 16 defined by the paired edge apertures 50, 52.
As indicated in the right-hand portion of FIG. 1, in some instances large diameter arcs or stripes are to be provided, for which there has been included a link member 30 joining together two of the instruments. Such a link member is illustrated in FIGS. 10-12 and includes a rigid channel 102 having opposite upstanding edges 104, 106. Edges 104 and 106 define a cavity portion therebetween dimensioned so as to accommodate, for instance, section 16 of two individual instruments 10. Channel 102 includes two sets of three each, upstanding lugs 108 for engaging respective paired edge apertures 50, 52 and an associated center-line aperture 46 on each of the section 16 members. As can be seen from FIG. 11, the separate section 16 members when placed end-to-end butt together at junction 110. Also, lugs 108 are dimensioned with respect to the apertures 50, 52 and 46 so as to resiliently, yet singly fit therein. The butted junction 110 and the snug fit engagement of lugs 108 in apertures 50, 52 and 46 enables the link member 30 to maintain the individual instruments 10 in position during use as illustrated in the right-hand portion of FIG. 1.
While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that various changes and modifications may be made without departing from the invention in its broader aspects. Accordingly, the aim of the appended claims is to cover all such changes and modifications as may fall within the true spirit and scope of the invention.
