Description
The instant invention generally relates to clip boards, and is more
particularly concerned with a clip board which both incorporates
unique internal storage facilities and has novel clamp means
associated therewith for fixedly retaining paper on the upper or
writing surface of the board.
It is a primary object of the instant invention to provide a clip
board wherein the clamping unit associated therewith is provided in
two individually operated laterally spaced sections capable of, in
addition to an individual clamping manipulation thereof, being
manipulated as a single unit, with the manipulation being effected
in a simple trouble-free manner.
Another significant object of the instant invention resides in the
provision of a clamping unit for clip board which is of a
relatively simple construction combining maximum paper clamping
ability with a highly desirable ease of operation.
In addition, an important object of the instant invention is to
provide a unique manner for storing as well as temporarily holding
a ruler or the like which can be used in conjunction with work
being performed on the clip board.
Basically, the above objects are achieved through the provision of
an enlarged board having a clip unit mounted on one end thereof and
including a pair of internal ruler receiving chambers, one being of
a depth capable of receiving the entire ruler which is subsequently
locked therein, and the other chamber being of a depth so as to
receive only a portion of the ruler with a portion of the ruler
projecting therefrom for easy access thereto during the use
thereof. The clamping unit itself includes a pair of laterally
spaced pressure members each biased downwardly into clamping
engagement with the writing surface of the board and each having a
separate lift member or arm associated therewith for effecting a
selected release thereof. The lift arms are activated by an upward
movement of the operating handles thereon and capable of being
locked in an elevated position.
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:
FIG. 1 is a perspective view of the clip board comprising the
instant invention with a portion thereof broken away for purposes
of illustration;
FIG. 2 is a partial top plan view of the clip board of the instant
invention with portions broken away;
FIG. 3 is an enlarged plan detail of a portion of the clamping
unit;
FIG. 4 is a transverse cross-sectional view taken substantially on
a plane passing along line 4--4 in FIG. 3;
FIG. 5 is a transverse cross-sectional view taken substantially on
a plane passing along line 5--5 in FIG. 2;
FIG. 6 is a transverse cross-sectional view taken substantially on
a plane passing along line 6--6 in FIG. 2;
FIG. 7 is a transverse view taken substantially on a plane passing
along line 7--7 in FIG. 5; and
FIG. 8 is a detail view illustrating the manner in which the
closure for the ruler storage chamber operates.
Referring now more specifically to the drawings, reference numeral
10 is used to generally designate the clip board comprising the
instant invention. This clip board 10 consists basically of an
enlarged generally rectangular flat board or panel 12 and a
clamping unit 14 mounted on the flat upper or writing surface 16 of
the board 12 adjacent the upper end thereof.
The board 12 has a pair of laterally spaced elongated internal
pockets or chambers 18 and 20 defined therein and opening through
the upper edge 22 thereof. These chambers 18 and 20 are
particularly adapted to receive a ruler or the like 24, the chamber
18 being of a depth so as to completely receive the ruler 24 below
an enlarged mouth end 26 within which a closure member 28 is
mounted, thus forming in effect a storage chamber for the ruler 24.
With particular reference to FIG. 8, it will be appreciated that
the closure member 28 is pivotally mounted to the board 12 at an
intermediate point along its length so as to move to a first full
line position paralleling the edge and overlying a sufficient
portion of the mouth end 26 of the chamber or pocket 18 so as to
preclude the movement of the ruler 24 therefrom. In this position,
it will be noted that one end portion of the closure 28 seats
within a recess 30 in the upper edge 22 so as to present a flush
appearance therewith and retain its orientation in overlying
relation to the chamber 18. When the ruler 24 is to be released,
the closure member 28 is pivoted to the phantom line position of
FIG. 8 so as to project partially into the enlarged mouth portion
26 of the chamber 18 and allow the movement of the ruler 24
thereby. The shorter chamber 20, noting FIG. 2, will receive the
ruler 24 with a portion of the ruler 24 projecting laterally from
the upper end 22 of the board 12. This chamber 20 will thus provide
a highly desirable pocket into which the ruler 24 can be
temporarily placed during use so as to retain the ruler 24 for easy
access thereto, rather than requiring the reinsertion of the ruler
24 into the storage chamber 18 which in turn would require an
inverting of the entire clip board 10 so as to withdraw the ruler
24 when its use is desired. In other words, the chamber 18
completely receives and stores the ruler 24, while the chamber 20
acts as a temporary receiver for the ruler 24 which will project
therefrom for easy access thereto.
Referring now specifically to the clamping unit 14, it will be
noted that this unit 14 includes an elongated U-shaped mounting
base 32 including front and rear parallel upstanding walls 34 and
36 interconnected by a flat bight portion 38 integral with the
lower edges of each of the walls 34 and 36. This bight portion 38
is positioned on the board writing surface 16 across the upper end
portion thereof and is rigidly affixed thereto in any suitable
manner, such as through the utilization of rivets 40.
The rear wall 36 has a mounting rail 42 integrally defined along
the upper edge thereof, this rail including lower and upper
horizontal wall portions projecting rearwardly from the rear wall
36 and interconnected by a rear vertical wall portion 48. The inner
edge of the upper horizontal wall portion 46 has a downwardly and
rearwardly angled forward wall portion 50 integral therewith and
terminating in spaced relation above the bottom wall portion
44.
The rail 42, through the opposite open ends thereof, slidably
receives the integrally formed mounting portions 52 defined
longitudinally along the rear edges of a pair of pressure members
54 which function, as shall be explained presently, so as to
releasably clamp paper or the like to the board 12. Each pressure
member 54, defined from a single rigid metal or plastic sheet,
includes a flat horizontal portion 56 which overlies the base 32
and terminates in a downwardly and forwardly angled portion 58
which in turn terminates in a vertical portion 60 directly
engageable against the upper surface 16 of the board 12 forward of
the front wall 34. The horizontal portion 56 is of course at an
elevation so as to be spaced vertically above the upper edge of the
front wall 34. With reference to FIGS. 1, 2 and 3, it will be noted
that each pressure member 54 is of a gradually increasing width
from the rear edge of the top plate portion 56. The mounting
portion 52 is integrally formed within the top portion 56 and
depends therefrom as will be readily apparent from FIGS. 4 and 5.
This mounting portion 52 includes a downwardly and forwardly
inclined wall portion 62 terminating in a horizontal rearwardly
directed wall portion 64 which overlies the lower horizontal
portion 44 of the mounting rail beneath the inclined portion 50 of
the mounting rail, with the horizontal portion 64 in turn
terminating in an upwardly and forwardly inclined portion 66 which
engages within the rail 42 between the generally vertical portions
48 and 50 so as to in effect pivotally retain the corresponding
pressure member 54 for movement between a first position engaged
with the writing surface 16 and a second position pivoted upwardly
approximately 45.degree. therefrom. It will be appreciated that the
hingedly related portions are so orientated relative to each other
as to preclude a disengagement of the pressure members 54 from the
mounting rail 42, while at the same time allowing for a free
pivotal movement of the pressure members 54 throughout the desired
range. As noted previously, the pressure members 54 will be mounted
on the rail 42 by a lateral sliding of the mounting portions 52
into the rail 42 between the opposite ends thereof. Once the
pressure members 54 have been located adjacent the opposite ends of
the base 32, suitable portions of the mounting rail 42 to each side
of each of the pressure members 54 can be slightly deformed, as at
68, so as to retain the pressure members 54 against sliding
movement.
Each of the pressure members 54 is to be resiliently biased into
its lowered paper clamping position by appropriate spring means 70.
The spring means 70 includes a central coil or coiled portion 72
mounted on a pin 74 affixed between the front wall 34 and a
vertical wall portion 76 immediately rearward thereof and
projecting integrally upward from the base bight portion 38, the
wall portion 76 actually being defined by a tab cut from the bight
portion 38 and bent vertically upward parallel to the front wall
34. The spring coil 72 is enclosed by a U-shaped housing 77 mounted
thereover and secured to the front wall 34 and wall portion 76 by
the pin 74, the opposed ends of which are provided with enlarged
retaining heads. With reference to FIGS. 2, 3 and 6, it will be
noted that the front wall 34, is actually recessed in alignment
with the spring 72 in order that the overlying front leg 80 of the
housing 77 and the head provided on the forward end of the pine 74
might provide a coplanar continuation of the front wall 34 to the
opposite sides thereof thus eliminating any undesirable projection
which might affect a proper alignment of received papers against
the vertical front wall 34.
The spring means 70 includes a pair of oppositely directed spring
arms 82 projecting laterally from the central coil 72, these spring
arms arcing upwardly and having the end portions thereof received
through holes 84 defined through the shanks 86 of a pair of headed
retainers or pins 88, each of which projects vertically through one
of the pressure members 54 and is retained thereon by an enlarged
positioning head 90. The spring means 70 is so tensioned as to,
through the spring arms 82, effect a constant downward biasing of
the pressure members 54 so as to effectively clamp papers or the
like to the board writing surface 16. Noting FIG. 7, it will be
appreciated that the spring arms 82, immediately beyond the pin
shanks 86, are downwardly inclined, thus facilitating a smooth
sliding through the shank passages 84 as the pressure members 54
are pivoted upwardly.
The raising or release of each of the pressure members 54 is
effected through a rod-like lift member 92 which consists of an
elongated body portion 94 rotatably mounted along the lower edge of
the rear wall 36 by a housing 96 affixed by rivets 98 or the like
extending through an integral horizontal projecting base portion
100 on the housing 96. The inner end of the rotatably received body
portion 94 has a forwardly projecting integral lift arm 102
thereon, this lift arm extending forwardly beyond the front wall 34
laterally to one side of the spring housing 77, and in turn
terminating in a laterally directed handle 104 positioned
immediately forward of the spring housing 77 and in parallel
slightly spaced alignment with the corresponding handle 104 on the
lift member 92 associated with the second pressure member 54. The
second end of the rotatably mounted body portion 96 of each lift
member 92 also includes a forwardly projecting integral arm 106
which is angled upwardly so as to engage the undersurface of the
corresponding pressure member 54 whereby a raising of the handle
104 of the corresponding lift member 92 will, through the rotatably
mounted body 96, effect an upward swinging of the arm 106 which in
turn will through the sliding engagement of the forward end of the
arm 106 with the undersurface of the pressure member 54, effect an
upward swinging of the pressure member 54. With the handles 104 of
the two pressure members 92 being located in spaced adjacent
orientation relative to each other, it will be appreciated that
both handles can easily be either individually or simultaneously
manipulated so as to effect a release of one or both pressure
members 54.
Each of the flat bases 100 associated with the pressure member
retaining housings 96 includes, at the inner end thereof, a
vertical wall 108 projecting perpendicularly forward from the rear
wall 36 and terminating in a lateral front wall 110. With reference
to FIGS. 1 and 2, it will be appreciated that the front wall 110
normally terminates laterally outward of the adjoining lift member
arm 102. However, inasmuch as each body portion receiving housing
96 is open at both ends, and inasmuch as each lift member body
portion 94 is longer than the associated housing 96, a lateral
sliding movement of each lift member 92 can be effected. The
purpose of this is to enable a selective locking of each of the
pressure members 54 in an elevated position. This is effected by
sliding the particular lift member 92 laterally outward so as to
position the elevated lift arm 102 over the upper edge of the front
wall 110, as indicated in FIGS. 3 and 4, whereby the front wall 110
will act so as to retain the lift member 92 elevated against the
biasing force of the spring means 70. It will be noted that in
laterally sliding one of the lift members 92, the free end of the
pressure member engaging arm 106 will merely slide thereunder and
still retain its lifting engagement with the pressure member 54.
Noting FIG. 1 in particular, it will be seen that a transverse
plate 112 is provided integrally with and transversely between the
vertical walls 108, this transverse portion 112 limiting the upward
swinging movement of the lift member arms 102 and also functioning
as a convenient means for suspending the clip board 10 from a hook
or the like.
Rearward of the rear base wall 36, and extending parallel thereto
for a major portion of the base 32, is a vertically projecting wall
114 which is affixed to the board 12 by an appropriate horizontal
base portion 116. The opposite ends of this vertical wall 114
include integral inwardly curled portions or flanges 118 which are
received about and retain the opposite ends of a bowed flexible
spring 120 which bows toward the adjacent rear wall 36 in general
underlying relation to the mounting rail 42. A suitable retaining
flange 122 is integrally formed along the upper edge of the
vertical wall 114 and projects inwardly therefrom in overlying
relation to the spring 120. The purpose of the spring 120 is to
releasably clamp a pencil, pointer or the like slidably inserted
between the walls 36 and 114 from either end thereof, FIG. 3
including a phantom line showing of a pencil 124 being
inserted.
From the foregoing, it will be appreciated that a unique clip board
has been defined, this clip board, in addition to incorporating
means for accommodating various implements to be utilized
therewith, including a ruler and pencil, also incorporates a unique
clamping unit. The clamping unit includes a pair of laterally
spaced pressure members which can be individually or simultaneously
manipulated through a pair of lift members which incorporate
operating handles located centrally on the board for easy access
thereto. The lift handles are moved upwardly in a simple manner,
normally utilizing a single thumb in engaging either one or both of
the handles with the movement of the handles being easily effected
through a substantially natural movement of the handle-engaging
thumb. Either or both of the lift members, subsequent to a raising
thereof, can be shifted slightly laterally outward so as to lock
the lift member or lift members in an elevated position, and
thereby retain the pressure members released from the clamped
material without requiring a continued engagement of the user's
hand therewith. Further, in view of the use of a common spring
means for both pressure members, and the specific orientation of
the spring means, it will be appreciated that a raising of one
pressure member will automatically increase the pressure on the
other pressure member to strengthen the holding force thereof.
Additionally, it should be noted that the vertical walls of the
base are also of significance in providing an effective means to
prevent a warping of the board.
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 described, and accordingly all suitable modifications and
equivalents may be resorted to, falling within the scope of the
invention as claimed.
