[0022] Reference is made to the accompanying drawings throughout the following detailed description. In the drawings, similar symbols typically identify corresponding or similar items throughout the several views. The use or disclosure of any incorporated literature in this detailed description is not an admission that the literature is prior art. The detailed description implements various embodiments of the present application by referring to the illustrative drawings. The drawings used are for illustrative purposes only and are not exhaustive or limiting. The scope of the present application is represented by the claims and their equivalents, rather than by the detailed description or the illustrative drawings.

[0023] Turning now to the drawings Figures 1-4A wallboard gauge, generally indicated at 10, includes a housing 12; a support arm 14 movable relative to the housing 12 to accommodate different heights of wallboard and vertical spacing; a lever 16 pivotable relative to the housing 12 to engage / disengage the wallboard gauge; and a fixed clamp 18 movable relative to the housing 12 to accommodate different thicknesses of wallboard. The housing 12, support arm 14 and lever 16 can be made of a suitable material, such as plastic, to avoid damage to the wallboard, and the fixed clamp 18 can be made of a suitable material, such as plated steel, to avoid damage to the wallboard.

[0024] In addition, turning to Figure 5 and 6 the housing 12 includes a through passage 30 extending along the length of the housing 12 for accommodating the support arm 14; a first opening 32 and a second opening 34 extending through a front portion of the housing 12 to the passage 30; a third opening 36 and a fourth opening 38 extending through a rear portion of the housing 12 to the passage 30, aligned with the first and second openings 32, 34, respectively; and a guide 40 within the passage 30 to guide and maintain the orientation of the support arm 14. The first and third openings 32, 36 are configured to accommodate a first fastener 42 perpendicular or substantially perpendicular to the axis of the passage 30. The second and fourth openings 34, 38 are configured to accommodate a second fastener 44 perpendicular or substantially perpendicular to the axis of the passage 30, and the fourth opening 38 is also configured to accommodate a fastener retainer 46 connected to the fastener 44.

[0025] The front portion of the housing 12 includes indicia, such as a notch 50 at the top of the front portion, for use as a measurement guide aligned with the indicia, such as a notch 52 on the support arm 14 for use as a display measurement guide. The back of the housing 12 defines a cavity 54 for accommodating a pad 56, a cavity 58 for accommodating an arm 60 of the fixed clamp 18, and includes one or more non-marring contact surfaces, such as a surface 62 for contact with the wallboard. The pad 56 can be a rubber pad that deforms against the front of the wallboard during use to prevent damage and increase clamping friction, and is configured to deform upon movement of the lever to one of the closed positions.

[0026] In addition, turning to Figures 7-12 and in particular the support arm 14, the support arm 14 is continuously movable relative to the housing 12 from a first position, shown at Figure 1 through the passage 30 to a plurality of other positions for use with different heights of wallboard or wallboard siding reveals, such as a second position, shown at Figure 10 and 11 and a third position, shown at Figure 12 wherein Figure 10 and 11The second position shown indicates a six-inch portion of the siding exposed. Figure 12 The third position shown indicates the eight-inch portion of the wall panel exposed.

[0027] The support arm 14 includes a body 70, which is configured to... Figure 1 The first position shown is adjacent to the top of the housing 12; and a pair of legs 72 and 74 extending from the body 70 and movable within the channel 30 of the housing 12. The rear side of the body 70 acts as a tip-protection lip, including a projection 76 extending from the bottom of the body to act as a support for a panel, such that when the panel gauge 10 is mounted on one panel, the bottom of the next panel being mounted rests against the projection, and the front of the next panel rests against the tip-protection lip. The sides of the projection may define a gripping area 78 for the user to hold when adjusting the display height of the gauge.

[0028] Legs 72 and 74 are laterally spaced to define a groove 80 that receives a guide 40 in the channel 30 of the housing 12. The front of each leg 72, 74 includes multiple markings or notations, such as multiple recesses 52 that are gradually spaced apart from each other. For example, leg 72 may include multiple recesses 52 spaced apart from each other in centimeter increments, the units of measurement indicated by reference numeral 82 and markings or notations, such as recess 84 indicating the number of centimeters of exposed wall panel. Similarly, leg 74 may include multiple recesses 52 spaced apart from each other in inch increments, the units of measurement indicated by reference numeral 86 and markings or notations, such as recess 88 indicating the number of inches of exposed wall panel, and recess 90 serving as a quarter-inch increment indicator.

[0029] like Figure 3 , 8 As shown in Figure 9, the inner surface of each leg 72, 74 facing the other leg 72, 74 to define the groove 80 is angled from back to front, such that the top portion of each leg 72, 74 is thicker than the bottom portion. The back surfaces of the legs 72 and 74 are configured to abut against an angled surface of a pressure plate 92, which is angled to correspond to the angle of the legs 72 and 74 (shown by reference numeral 94). The pressure plate includes an opening for receiving the fastener and defines a container on the back side of the pressure plate for receiving a locking nut that engages with the fastener. The pressure plate 92 includes an opening 96 through which a first fastener 42 extends and defines a receptacle 98 on its rear side to receive a locking nut 100 that engages with the first fastener 42, for example, by a threaded connection.

[0030] When the first fastener 42 is twisted, it applies an axial force to the locking nut 100, which presses against the support arm 14 between the pressure plate 92 and the housing 12. The torque applied to the first fastener 42 is proportional to the clamping force. The interaction between the inclined surfaces of the legs 72 and 74 and the inclined surface of the pressure plate 92 increases the retention force of the first fastener 42 in the main load direction (as indicated by reference numeral 102), thereby eliminating or reducing slippage of the support arm 14 under load. The increased retention force allows for the use of non-metallic components (e.g., plastic components) and allows for the use of fasteners that apply lower torque (e.g., Phillips head screws).

[0031] Now turning Figure 13 and 14 The following will describe lever 16 in detail. Lever 16 is in the first upward closed position ( Figure 1 and Figure 10 (As shown by reference numeral 110 in the attached figure), open location ( Figure 1 and Figure 11 (As shown by reference numeral 112 in the attached figure) and the second downward closing position ( Figure 1 The lever 16 (shown as reference numeral 114 in the attached figure) is movable between the two parts. The lever 16 includes a body 116 for the user to grip and a pair of legs 118 and 120 extending from the body 116 and spaced laterally from each other. The body 116 includes a front region 122 for receiving a label 124 containing product information, etc.; and a rear region 126 that defines a gripping area, which may be textured to prevent slippage when the user grips it.

[0032] Each leg 118, 120 has an inner portion 130, 132 and an outer portion 134, 136 and a channel 138, 140 extending through each inner portion 130, 132 and outer portion 134, 136 in the transverse direction for receiving a pin 142. The pin 142 includes an opening 144 for receiving the second fastener 44 to connect the bar 16 to the housing 12 and to allow the bar 16 to pivot relative to the housing 12. The inner portions 130, 132 are connected to each other by a joint 146 and, together with the joint 146 and the body 116, define an opening 148 that allows access to the second fastener 44 when the bar 16 is in the open position 112. The back of each inner portion 130, 132, together with the adjacent outer portion 134, 136, defines a channel 150, 152 for receiving the corresponding protrusion 64 on the front of the housing 12 when the bar 16 is in the first closed position 110. The back of each inner portion 130, 132 also has a cam surface 154, 156 that, when in the first closed position 110, presses against the housing 12 to pull the clamp 18 toward the housing 12 to clamp the gauge 10. Likewise, the front of each inner portion 130, 132 includes a cam surface 158, 160 that, when in the second closed position 114, presses against the housing 12 to pull the clamp 18 toward the housing 12 to clamp the gauge 10. When the bar 16 is in the open position 112, the head of the second fastener 44 will be moved toward the housing 12 to provide loose space on the wallboard for placement of the wallboard gauge 10. Once positioned, the bar 16 can be moved to the first or second closed position to clamp against the wallboard.

[0033] Turning again to Figure 4 To assemble the wallboard gauge 10, the first fastener 42 can be inserted through the first opening 32 of the housing 12 into the channel 30, as well as the press plate 92 and locking nut 100 located in the channel 30. The first fastener 42 is then inserted into the opening 96 in the press plate 92 and rotated clockwise to threadedly engage the locking nut 100. The first fastener 42 can be further rotated until the end of the first fastener 42 extends through the third opening 36 in the housing 12. The pad 56 can be placed in the cavity 54 on the back of the housing 12 and secured in place in a suitable manner, such as by adhesive.

[0034] Pin 142 can be placed in passage 138 and 140 of stem 16 with opening 144 between inner portions 130 and 132. Stem 16 can then be placed adjacent housing 12 with second fastener 44 inserted into opening 144 of pin 142 and opening 34 of housing 12. Fastener retainer 46 can be secured to or formed integrally with securing clip 18. For example, protrusion 170 on fastener retainer 46 can be received in opening 172 on securing clip 18 and secured in an appropriate manner (e.g., by adhesive, welding, etc.). Resilient element 174 (e.g., a compression spring) can be placed on fastener retainer 46, which is then inserted into opening 38 of housing 12. Second fastener 44 can then be connected with fastener retainer 46, for example, by rotating second fastener 44 clockwise to threadably engage second fastener 44 and fastener retainer 46. It should be appreciated that although described above in a certain order, wall gauge 10 can be assembled in any suitable order.

[0035] Turning again to Figure 1 , 10 and 11, the operation of wall gauge 10 will be described in detail. To adjust the display height, the user will loosen first fastener 42 and move the support arm to the desired display height (if known), for example, a display height of six inches; or the user can hold wall gauge 10 against a piece of wallboard and then move the display arm to set the display height. Support arm 14 is moved continuously in passage 30 rather than in preset increments. After the display height is set, the user tightens first fastener 42, which exerts an axial force on lock nut 100 that compresses support arm 14 between pressure plate 92 and housing 12 to hold support arm 14 at the desired height and prevent slippage in the event of a drop or high weight slide.

[0036] The user can then adjust the thickness of the wall gauge, or the thickness of the wall gauge can be adjusted prior to setting the display height. To adjust the thickness, the user can loosen the second fastener 42 to increase the distance between the fixed clip 18 and the housing 12, and then position the wall gauge 10 on a piece of wallboard using the lever 16 in the first upwardly closed position or the second downwardly closed position. The user can then tighten the second fastener 42 as desired to clamp the wall gauge 10 to the piece of wallboard. The user can then move the lever 16 to the open position to create a loose space to remove the wall gauge from the piece of wallboard. Alternatively, the user can loosen the second fastener 42 to increase the distance between the fixed clip 18 and the housing 12, and then position the wall gauge 10 on a piece of wallboard using the lever 16 in the open position. The user can then tighten the second fastener 42 as desired through the opening 148 to retain the wallboard between the fixed clip 18 and the housing 12, for example by hand tightening. Movement of the lever to the first upwardly closed position or the second downwardly closed position will provide additional pressure to clamp the wall gauge to the piece of wallboard when the user positions the wall gauge 10 on the piece of wallboard.

[0037] Once the display height and thickness have been set, the wall gauge can be positioned on a piece of wallboard using the lever 16 in the open position, and then the lever 16 can be moved to the first upwardly closed position or the second downwardly closed position to clamp the wall gauge 10 to the piece of wallboard and allow another piece of wallboard to be installed.
