SHEEI 5 BF 5 56 I 1 3' ivl l l l OBSERVATION SIGNAL DEVICE AND COMPONENTS THEREOF The present invention relates ,to panel signals used in geodetic work, general land surveys, safety work and the like and, more particularly, a new and improved panel signal that can be very lightweight, made a selfcontained unit, and have incorporated therein panel mounts adapted to spill oncoming gusts of wind from the outer edges or margins of the panel because of the type of panel and panel mounting construction.

For geodetic work and general land surveys, helicopters are often employed to transport bulky lumber, carpenters and other workmen to mountaineous or hilly sites for the erection of panel signals. Such panel signals are now constructed of wood, are very rigid and bulky, difficultto tie down and blow over easily during windstorms. Additional disadvantages are that such panel signals as are conventionally used require extensive materials and workmen to erect. These panel signals, so-called, are used for telescopic sighting purposes in order that a given terrain can be mapped or surveyed.

The present invention overcomes prior difficulties in that, first of all, the unit can be made principally of light-weight aluminum tubing, at least so far as the outer casing and certain other structure is concerned. Disposed within the tubing enclosure are primary, collapsed structure which is tied centrally so as to keep the panels proximate the central tubular structure. Release of the tie means automatically releases the panels such that the same spring out naturally to reveal plural panels or flags individually held in vertical condition. The rods or shafts mounting the flags to the central structure are resiliently mounted such that wind spillage is possible. This is to say, certain ones of the flags, when disposed essentially transversely to the direction of oncoming wind, will tend to deflect rearwardly slightly and also assume temporary forwardly concave configurements such that oncoming winds will be spilled off of the outer edge of the respective flags or signals.

Self-contained structure includes extension and tiedown structure such as to keep the plural-panel signal erect when mounted. The signal itself can be erected upon solid rock or simply conventional turf, sand, or soft earth.- Container structure is provided for housing cable or rope ties and also isconstructed to receive location information. The structure is adapted for incorporation of any number of flags or panels. The panels themselves can be numbered, uniquely colored, or contain other indicia. The subject panel signals are usable not only for general land and geodetic survey work but also by arms and defense forces, by emergency crews, and for all types of highway work.

Accordingly, a principal object of the present invention is to provide a new and improved panel signal structure.

An additional object is to provide a multiple panel signal for use in geodetic and general land survey work and for other uses.

An additional object is to provide a self-contained panel signal.

A further objectis to provide a panel signal having plural panels or flags which are constructed and mounted to adapt oncoming wind pressures to spill out over the ends or outer margins of such panels.

The features of the present invention may best be understood by reference to the following description taken in connection with the accompanying drawings in which:

FIG. 1 is a front perspective view of the selfcontained structure when packaged and sealed preparatory to use.

FIG. 2 is similar to FIG. 1 but illustratesthe structure and manner by which cap removal of the case or container of the signal device is removed.

FIG. 3 is an exploded view of the structure of FIGS. 1 and 2, illustrating a principal portion of that which is contained within the case and lid of FIGS. 1 and 2.

FIGS. 4 and 5 are front elevation and section views of a principal portion of the structure, illustrating stored tie-down structure as well as vertical lengthening structure, and also illustrating the flags or panels as being in retracted position.

FIG. 6 is a serially exploded view illustrating the stored contents of the principal flag and mounting structure of the invention.

FIG. 7 is a front elevation of the panel signal of the present invention wherein the same is erected for use.

FIG. 8 is an enlarged fragmentary top plan illustrating a representative collar structure of the panel signal wherein a four-panel-system is utilized, thereby insuring that the mounting means are disposed in guadature.

FIG. 9 is a view taken along the line 99 in FIG. 8 and illustrates, in an extension thereof, a representative mounting at the lower margin of a represented panel to the structure.

FIG. 10 is similar to FIG. 8 but illustrates that in a three-flag or three-panel system the resilient mounting means incorporated may be'disposed apart.

FIG. 11 is a fragmentary view taken along line 11-11 in FIG. 10.

FIG. 12 is a side elevation of a representative spring mount used in resiliently mounting the rods or shafts supporting the individual flags.

FIG. 13 is a fragmentary section taken along the line 1313 in FIG. 9, illustrating a particular clamping structure used to clamp the panel or flag to a respective rod mounting the same.

FIG. '14 is an enlarged fragmentary view of the bottom of the panel signal structure wherein a pointer is used to position the structure over a centering cone shaped recess.

FIG. 15 is similar to FIG. 14 but illustrates an inversion of the pointer structure such that an upstanding point may be centered underneath the panel signal to be mounted thereover.

In FIG. 1 the case 10 of the device is fitted into the interior of lid 11, and these two maybe temporarily seabout the juncture 14 as to case 10 and lid 11. Thus,

the tape 12 will be wrapped over the string in the manner illustrated in FIG. I.

As an alternative approach, there may be an enlarged label 15 disposed essentially completely over the case and lid 11. Solely the upper or right end of the label at is illustrated in FIG. 2. In any event, such a label can identify the product and also give instructions as to erection and use. Prior to the inclusion of a gummed or self-sealing label on the case, there may be preliminarily wrapped about the juncture 14 the severing string 13, this in a manner such that the outer end of string 13 protrudes outwardly. In such event it will be easy for the user to pull in the direction of the arrow shown in FIG. 2 such that the lid 11 may be separated from case 10.

In any event, upon opening the case 10, as by removal of lid 11, see FIG. 3, it is seen that there may be withdrawn a structural assembly SA, which will now be explained. Preliminarily, it is noted that a self-locking or other 'type of strap 17, made from plastic by way of example, may be used to secure inwardly, relative to tube body 18, the four outwardly extending arms 26, at the top of the structure, and also four arms 26, at the lower portion of the structure. FIG. 3 illustrates a fourpanel construction as will hereinafter be pointed out. It will be apparent that plural panels such as two, three or any desired number may be utilized in the construction by the general teaching of .the present invention.

In any event, FIGS. 4 and 5 illustrate a collar disposed at opposite ends of tube body 18. The collar 20 includes four bosses 21 disposed in quadrature and which individually receive the spring ends 22, at aperture 23, of a respective tapered flexure spring 24. There will be provided four bosses 21, each receiving a respective flexure spring 24, in the manner shown in FIG. 5. The springs are shown detailed in elevation view in FIG. 4, and merely the base portions thereof at B in FIG. 5 are illustrated. In FIG. 5 it is seen that an intermediate turn at T is angulated outwardly such that the positionment of the spring end at X, at each spring emplacement, will serve to apply a tension force to the spring member and hence aid the same in being firmly, retentively, and springingly secured within the respective boss aperture shown.

The outer end of each spring 24 is secured, as by a press fit or by solder, to the enlarged receiving end 25 of a respective arm 26. Accordingly, since each of the springs accommodates a respective 'arm 26, there will thus be provided four arms to the top of the structure, as seen in FIG. 4, and likewise four arms to the bottom of the structure. If desired, a rounded-end or tip element 27', having an internal bore as at 28, may be provided to give a rounded tip to each of the arms 26. In any event, as the strap 17 is removed, the springs 24 will co-act together to spring outwardly and hence cause the four panels 26, arranged in quadrature, and two of which are shown in FIG. 7, to become vertically erect. The panels 27 may be secured to their respective arms 26, two per panel, by means of sewn margin looptype seams, as at 28' in FIG. 7.

As to the panels themselves, they may be made of screen material, cloth, or other type of materials such as a wire mesh, or even plastic In returning to FIG. 5, it will be seen that a container 28 is provided, the same including a cap or lid 29. The container contains a series of individually wrapped cord lengths 49-52. In usual constructions there would be provided four such cord lengths. The cord lengths are seen to be attached to a lower tie-down ring 32; the

cords are retained in place by knotted ends 33. The lower tie-down ring 32 is likewise illustrated in FIG. 6. Container 28 is likewise shown on the righthand side of FIG. 6. Thus, the sole equipment contained by the separate container 28 will be simply the lower tie-down ring 32, having the four separate wrapped cord lengths 4952. To complete the upper portion of the structure, as in FIG. 5, there will be provided a flange 34 which is riveted in place, and also to the spring-retaining boss, by respective rivets 35.

FIG. 5 illustrates that there are a number of items of stored equipment disposed for packing purposes within the structure 18. Thus, there will be a series of petons or stakes 36 having their individual eyelets 37 as serving as rope tie-downs. The steel stakes or petons 36 will be used in the case where the device is to be secured to rock formations. Where ground use is contemplated, that is, where wooden stakes will suffice, then the same are supplied as at 38, with each including a cord mounting groove 39. Centering point element 40 is likewise provided and includes a central flange-like protuberance 41 as well as point 42' and recess 43. Member 40 can be either positioned as shown in FIG. 5, or inverted, relative to lower extension tube 42, such that when the equipment is to be installed and centered either over a point or over a dot, the equipment and especially member 40 can be used, see FIG. 7, to properly orient the structure. Thus, either the lower tip at 40 may be employed over a dot or simply a metal marking pin or, if a point is upstanding, then the member 40 may be inverted such that the point recess 43 may be fitted over the upstanding point. Additional tubes 44 and 45 are likewise provided, with tubes 42, 44 and 45 serving as respective telescoping extensions of one an other, see FIG. 7. Thus, each of the tubular members may be constructed so that one end, i.e., the lower end of tubular member 45, will fit into the upper end fitting extremity 46 of tubular member 44. FIG. 7 illustrates that the lower tie-down ring 32 is preliminarily slipped over tubular member 42 and abuts against shoulder S of lower tubular member 42 so as to be retained thereat and thus prevented from being drawn upwardly. The lower tie-down ring 32 is retained in place, however, by the outwardly extending ties 49-52, which are connected to main ties or cord lengths 31. FIG. 7 illustrates that the wood stakes 38, of FIG. 5, may be utilized to secure the lower ends of the tie-down cords 31.

Thus, FIG. 5 illustrates that the interior of tubular structure includes tie-down stakes, center point, and extension tubes 42, 44 and 45. These are removed after container 28 is removed, as above described. Tail cone 50 is shown to include an arcuate portion 51 which mounts over flange portion 52 of lower flange 53. The latter is riveted in place by rivets 54 to the lower collar 20 which also includes the four plastic bosses in a manner similar to that in connection with the upper collar 20. The tail cone flange, see 56 in FIG. 6, is provided with a series of apertures 57 for accommodating attachment thereto by the upper extremities of cords 31. It is seen in FIG. 3 that the cord lengths 31 are preliminarily secured to the flange 56 of tail cone 50'.

FIGS. 14 and 15 illustrate various ways in which the equipment may be centered, as by the use of the centering means 40 shown therein. Point P1 is a ground reference point in FIG. 15. Indentation I, in FIG. 14, is a reference point for receiving the apex of point member 40.

FIG. 8 is a fragmentary plan view, partially in section, illustrating the flexure springs as being in quadrature for supporting the sails. The several flexure springs at 24 are illustrated in FIG. 12. For securement of the sails, themselves, a pair of U-configured clamps as at 53 and 54 may be employed. These serve as crimping clamps which are simply crimped by pliers to secure the outer extremity of the particular sail, flag, or panel in question to desired points along respective arms 26.

FIGS. 10 and 11 illustrate an optional embodiment of the invention wherein three instead of four sails are used. In such event, the supporting springs will be disposed l apart so that three sails are utilized.

FIG. 13 illustrates that if desired the clamps 53 and 54 may be of round configuration so as to clampingly engage a particular sail or panel to its rod.

It should finally be added that the upper container or container 28 with cap 29 may be utilized for repositioning and to contain a message as to the survey being conducted, by way of example.

The subject equipment is highly advantageous for use for forest service, engineering surveys, geodetic surveys, general land, industrial or pipe line surveying, and also as emergency equipment for highway use, by way of example. The equipment is also ideally suited for army engineering work, hospital zoning and a variety of other uses.

The panels or sails, themselves, may include any type of emergency indicia, lettering numbers, and so on.

In operation, the lid 11 is removed from case 10, as is shown in FIG. 2, so that the central structure seen in FIG. 3 may be withdrawn. Upon such withdrawal the tape or strap 17 is removed such as to permit the sails, flags or panels 27 to become erect and disposed outwardly, as seen in FIG. 7. Actually, either before or after the removal 'of the tape 17, there may be withdrawn from the interior of the structure, as seen in FIG. 5, the various extension tubes, stakes, and center point 40, to effect structure erection. The base tie-down ropes or cords as at 31 in FIG. 3, are unwound and staked and, with the lower ring 32 being in place, its cords 49-52 will be tied at medial points to the various cords 31. Printed or written survey information may then be installed in container 28 and the same replaced with its lid 29.

For identification purposes, four-sail units may be used as primary markers for geodetic surveys, with three-sail units, as illustrated in FIGS. 10 and 11, used for secondary markers. This is purely optional. 7

For added stability the extension tubes at 42, 44 and 46 may be filled with sand, this to lower the center of gravity of the unit. While it is preferred that the sails, flags or panels be perforate, such as wire, cloth, mesh or screening, yet the same can be of a solid, nonperforate material such as plastic; in any event, under wind loads the supporting arms for each panel will distort inwardly by virtue of an inherent flexure or because of flexure mountings, such that the panels will become distorted such that wind loads may spill over at outer vertical extremities.

While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art the various changes and modifications which may be made without departing from the essential features of the present invention and, therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
