7 Claims. (Cl. 281 44) The present invention generally relates to clip boards, and is more particularlydirected to a clip board incorporating novel means for fixedly retaining paper on the upper or writing surface thereof.

A primary object of the instant invention is to provide a means for enclosing and resiliently clamping the bottom portion of one or more sheets of paper to the upper surface of a clip board, this being done in conjunction with an independently releasable means for engaging and clamping the top portion of the paper. I

Another significant objectof the instant-invention.

is to provide that the means for clamping the bottom of the paper be alternately useable as a means for aligning one or more sheets of paper, and further, as a hand rest instant invention.

FIGURE 11 is a partial perspective view, with portions broken away, of the bottom end of a modified clip board panel having a modified flap mounting means thereon; and 7 FIGURE 12 is a partial cross-sectional view taken substantially on a plane passing along line 1212 in FIG- the upper surface 28 of the panel 22 adjacent the top end to provide means for'resiliently retaining the bottom clamp means in each of its adjusted positions.

Also, it is an object of the instant invention to provide a novel means for clamping the top portion of paper to the clip board utilizing a pair of pressure members capable of being simultaneously or independently released.

In addition, it is an object of the instant invention to provide means mounted on the writing surface itself which cooperate with the pressure members so as to prevent movement of the clamped paper.

Further, it is an object of the instant invention to provide paper retaining pressure members which are formed so as to allow for adjustment to minor surface irregularities.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 end thereof orientated for use thereof, this upper surface 28 being flat so as to provide a writing surface upon which one or more papers 30 are to be received and retained in position by both the clamp means 24 and the flap means 26. The clamp means 24 includes a generally U-shaped mounting base 32 including front and rear parallel walls 34 and 36 interconnected in' spaced relation :by a flat bight portion 38 integral with the lower edges of each of the walls 34and 36. The rear wall 36, which is of a greater heightt-han the front wall 34, includes a coplanar centrally located upwardly projecting rigid tab or grip 40 for use as a fixed point toward which the handle loops 42 of the pressure arms 44 are drawn when raising or releasing these pressure arms 44;

Each of the two pressure arms 44 includes anelongated portion 46rotatably mounted on the forward face of the rear wall 36 by a pair of bearing straps 48 having the opposite ends thereof extending through apertures 50 in the rear wall 36 and subsequently being bent in op The elongated portions 46 of each tions 46 being angularly bent so as to prevent longitudinal movement of the pressure arm 44 withinthe bearing straps 48. Each of the pressure arms 44 further includes, integral with the inner ends of the elongated portions 46, upwardly and inwardly angled portions 54 terminating in the aforementioned loop handles 42. The angularly bent outer end of portion 52 of each 'of the pressure arm portions 46 .has integrally formed therewith a portion 56 angled upwardly at an angle similar to that of the portion 54 and subsequently forwardly to a point.

so as to bring the press feet 60 into clamping engagement,

with one or more papers 30 located upon the upper sur-' face 28 of the panel 22 by spring means 62 located adjacent therear face of the front wall 34 by a pair of spaced retraining tabs 64 struck upwardly from the bight portion 38 of the mounting base. 32. This spring means 62 consists of a. central coil 66 mounted on a cross pin 68 O secured to the walls 34 and 36, and a pair of oppositely 5 in downwardly opening hook portions 72. These hook" directed spring arms 70 terminating, at their outer ends,

Incidentally, it will be noted that the portions 72 are engaged with the forwardly directed portions 56 of the pressure arms 44 through loops or straps 74 which are retained in position on the portions 56 by means of a slight kink or depression 76 in the portion 56. In this manner, through the action of the coiled central portion 66, the spring means 62 acts so as to bias both pressure feet 60 downwardly into engagement with the material, generally paper 30, to be clamped. When it becomes desirable to release either or both of the pressure feet 60, this is accomplished by moving the loop handles 42 rearwardly toward the gripping tab 40.

The instant invention also contemplates the provision of a pressure pad 78 associated with each pressure foot 60 and secured to the panel 22 directly beneath the corresponding pressure foot 60 for use in conjunction therewith for retaining the paper 30. These pressure pads 78 are preferably as long as or slightly longer than thefect 60 and are of a friction creating material so as to prevent any tendency for the paper 30 to slide on the surface 28. Further, while these pads 78 have been illustrated as raised slightly above the writing surface 28, it will be appreciated that they can be formed either flush with or even slightly below the writing surface 28 if so desired.

A removable cover 80 is provided for the mounting base 32 and includes a fiat upper panel 82 having portions 84 thereof removed so as to allow passage of the tongue 40 and loop handles 42 therethrough. Depending peripheral flanges 86 are also provided for resiliently engaging the walls 34 and 36 for retaining the cover 80 thereon. In addition, if so desired, an elongated pencil retaining clip 88, having parallel resilient walls can be provided,

the construction of this clip 88 being obvious drawings.

The instant invention also contemplates the provision of means for mounting or suspending the entire clip board 20,,this means being in a form of a suspension hook 90 consisting of an elongated shank 92 having an enlarged circular head 94 at one end thereof and a hook portion 96 at the other end thereof. The suspension hook 90projects from the top end of the clip board 20 and has the shank portion 92 thereof rotatably received within a passage formed by arcuately deforming that portion of the bight portion 38 between the struck up retaining tabs 64. arcurately formed central portion is in effect three portions, a first portion 98 located forward of the struck up tabs 64, a second portion 100 defined by the struck up tabs 64 and having a free rear edge, and a third or rear portion 102 located rearward of the openings left by the struck up portions 64. The head 94 on the shank 92 is from the As will be appreciated from the drawings, this silient position retaining spring 112. The right angular hinge strap-108 is secured to the bottom end of the-panel 22 by suitable fasteners 113 with one leg thereof engaged flush against the lower surface of the panel 22 and with the other leg engaged flush against the bottom end of the panel 22, this leg having the upper edge thereof located substantially in the plane of the upper or writing surface 28 and formed so as to provide a series of hinge knuckles 114. The flap 110 includes a relatively narrow portion 116 having the free edge thereof formed so as to provide a plurality of hinge knuckles 118 interrelated or intermeshed with the knuckles 114 for the reception of a hinge pin 120 therethrough, and a relatively wide flap portion 122 having a centrally located finger thereof secured to the flap 110 in the vicinity of the joint between the portions 116 and 122 by means of a headed pin 128 having the shank thereof clamped within a bore provided by cut out and deformed portions 130 of the flap 110. The end of the spring 112 fixed to the panel 22 is orientated in a plane which will be below the plane of the opposite 'end of the spring 112 when the flap is orientated in a first position overlying the bottom ends of the paper 30, 'as illustrated in FIGURE 1, and above the plane of the other end of the spring 112 when the flap is orientated so a'sto project outwardly from the bottom end of the panel 22, as seen in FIGURE 2. In this manner, aresilie'nt elongation of the spring 112 is necessary when moving the flap from one position to the other, thereby resulting in a resilient retention of the flap in these positions. In the first mentioned position, it will of course be appreciated that a clamping of the bottom end of the paper 30 is effected, while in the second position an extension is provided for use as a hand or arm rest when Writing on the paper, this being particularly desirable as the bottom end of the paper 30 is approached. The instant invention. also contemplates a third or intermediate position for the flap 110, this position being illustrated in full lines in FIGURE 3 and consists of the flap portion 122 projecting perpendicularly from the plane I of the writing surface 28 so as to provide a ledge or surlocated just forward of the arcuately formed portion 98 in a slot 104 which allows the head 94, and consequently the entire suspension hook 92, to rotate freely while preventing longitudinal movement of the suspension hook 90. In order to resist rotational movement of the suspension hook 90 so as to prevent accidental dislocation or disorientation of the hook 90, it will be noted that the arcuately formed portion 100, this best being seen in FIGURES 3 and 4, is downwardly bent or angled so as to resiliently engage its free rear end with the shank 92, thereby providing a slight clamping of the shank 92 so as to, while allowing a rotation of the suspension hook 90, tending to resist this-movement to a degree contemplated to prevent accidental movement. It will of course be appreciated that a suitable aperture 106 is provided in the rear wall 36 for the passage of the suspension hook therethrough. I p

Turning now to the flap means 26 mounted on the bottom end of the panel 22, it will be noted that this flap means 26 has been illustrated as extending across the full width of the bottom of the panel 22,' this being preferred, however, if so desired, the flap means 26 can beof length less than the width of the panel 22. The flap means 26 consists basically of an elongated right angular hinge strap 108, a generally right angular flap 110, and a re face against which the paper 30 can be abutted so as to align asta'ck of papers, or support the papers freely while the clamp means 24 is being adjusted. The flap 110 is resiliently and releasably retained in this position through cpadle or saddle shaped heads 132 provided on the opposite ends of the hinge pin 120, these cradles 132 being of a size so as to releasably-receive the springs 112 as the flap 110 is moved into the full line position of FIG- URE 3, the spring 112 along each edge of the panel 22 flexing outwardly over the high point of the corresponding cradle 132 and subsequently into the cradle recess as the flap portion 122 assumes the perpendicular position. Further movement of the flap in either direction is prevented until a suflicient force is applied so as to cause the spring 112 to move over the cradle defining raised portions of the cradle 132. With reference to FIGURE 7, it will be noted that the flap knuckles 118 fixedly receive the hinge pin While the hinge strip knuckles 114 loosely receive the hinge pin 120, thereby providing for a rotation of the hinge pin 120 and saddles 132 with a movement of the flap 110, this rotation of the cradles 132 tending to facilitate the introduction of the springs 112. As Will be appreciated from a comparison of FIGURES 1, 2 and 5, the cradles 132 are, in the two extreme posiposition the recesses are orientated parallel to the panel 22 for reception of the springs 112 therein. Incidentally, as will be appreciated from FIGURE 3, when the flap 110 is in its rest forming position, the narrow flap portion 116 is engaged against the upwardly extending leg of the hinge strap 108 which forms in effect an abutment for properly orientating the flap 110 so as to extend outwardly in a plane generally parallel to the panel 22.

Referring now to FIGURES 11 and 12, it will be noted that a slightly modified form of flap means 134 has been illustrated therein. This particular flap means 134 is specifically formed for mounting on extremely thin panels 136, such as for example aluminum panels, as compared to the more conventional wood panels as illustrated in FIGURE 3. One of the differences in the flap means 134 as compared to the flap means 26 is the provision of a cleat 138 fixed to the lower surface of the panel 136 so as to project laterally therebeyond, the cleat 138 including an upwardly angled tab 140 to which the end of the tensioning spring 112 is secured. Another difference resides in the modified hinge strap 142 which is riveted to the lower surface of the panel adjacent the bottom edge thereof and includes an angularly directed portion 144 so as to provide a relatively wide portion 146 engaged against the bottom end of the panel 136 and capable of providing a substantial abutment surface so as to maintain the flap in a position corresponding to the position of the flap in FIGURE 2 so as to act as a hand or arm rest. In other words, inasmuch as the panel 136 is in itself too narrow to provide a proper abutment surface, the hinge strap 142, rather than conforming. directly to the panel 136 includes an additional angularly related portion 144 therein between that portion which engages flush against the under surface of the panel 136 and that portion which engages flush against the bottom end of the panel 136 so as to in effect increase the width of the bottom edge engaging portion 146.

From the foregoing, it will be appreciated that a highly novel clip board has been defined, this clip board incorporating unique means for clamping both the top and bottom ends of paper so as to'provide a stability to the paper which has heretofore not been available in clip boards and which can be highly desirable under adverse conditions. In addition, the instant invention has provided a means for clamping the bottom end of the paper which can alternately be used as a means for aligning the paper or retaining the paper while the upper clamp is being adjusted and as a hard or arm rest while writing on the paper positioned on the clip board panel. Incidentally, while the piano hinge construction in FIGURE 3 has been shown slightly above the writing surface, it will be appreciated that this joint can be orientated flush with or even slightly below the writing surface. Further, while only a single hinge pin 120 has been described, it will be appreciated that two separate hinge pins, each having one of the cradles thereon, can alternately be used.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and de scribed, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
