Expanding Pedalboard

Abstract

The invention describes a pedalboard for holding instrument effect pedals (guitar, bass, etc) which stores two layers of instrument effect pedals upon vertically stacked platforms for more compact storage but which can also be opened/expanded using a four-bar linkage mechanism to allow for access to the lower effect pedals during musical performance or practice. The upper platform may be disconnected from the front links and can pivot upward to allow for further access to the lower platform.

Claims

1. A pedalboard which comprises at least two platforms upon which effect pedals are to be affixed, where said platforms are able to vary in orientation towards one another by means of a four-bar linkage mechanism. The lower platform acts as the ground link of the mechanism and is attached to the upper platform(s) by a front rocker link and a rear rocker link. The platforms are able to alternate between a more compact orientation wherein the upper platform(s) is positioned above and obscures the lower platform, and a more open orientation wherein the proportion of the lower platform that is obscured by the upper platform(s) is less than in the compact position. The pedalboard is able to transition between these two positions by means of applying a force (either human or mechanical) to one or more of the components of the four-bar linkage.

2. The pedalboard described in claim 1 with additional four-bar linkage assemblies acting in parallel to provide greater stability to the pedalboard in both static positions as well as during transitions between positions.

3. The pedalboard described in claim 2 wherein parallel four-bar linkages are conjoined by shared links in order to stabilize the structure and synchronize the movement of linkages during transitions between positions.

4. The pedalboard described in claim 1 with a frictional surface on the upper and lower platforms suitable for fastening effect pedals.

5. The pedalboard described in claim 1 with a fastening mechanism between the upper platform and the front rocker arms such that the upper platform may become temporarily detached from the front rocker arms.

6. The pedalboard described in claim 1 with holes or channels in the upper platform allowing for the passage of signal cables or power cables down to the lower platform and vice versa.

7. The pedalboard described in claim 1 with a locking mechanism to prevent the pedalboard from unintentionally transitioning between positions.

GENERAL DESCRIPTION OF THE INVENTION

[0029] The invention describes a pedalboard which allows for the compact storage and transportation of guitar effect pedals while being easily repositionable to an alternate orientation which is less compact but more suited to the ergonomic use of said pedals. The pedals rest on two or more platforms which are positioned above one another while being stored, and then positioned offset from one another during use. Transitions between these positions are accomplished by joining the platforms to each other with pivotable rocker arms, forming a four-bar linkage. Advantageously, the separate pedalboard orientations for storage and use can each be optimized for their respective roles by using appropriate rocker arm lengths, joint locations, and stopping positions.

DETAILED DESCRIPTION OF THE INVENTION

[0030] FIG. 1 shows an embodiment of a pedalboard 100 which comprises an upper platform 106 and a lower platform 108 upon which instrument effect pedals or other audio processing units may be affixed. The platforms 106, 108 are able to be repositioned into distinct orientations which are better suited to various purposes. The pedalboard may be composed of any suitably strong and durable materials such as wood, plastic, metal, or any combination thereof.

[0031] In FIG. 1 the platforms are stacked vertically above one another for a compact box-like shape which is optimized for storage and travel. In FIG. 2 the platforms 106, 108 have been offset into a less compact but more open position which provides greater access to the effect pedals during a performance or practice. FIG. 3 shows an additional variation of the open position where the upper platform 106 has been tilted back to fully reveal the lower platform 108, allowing for complete access to the lower platform 108 and the underside of the upper platform 106. This is a favorable position for maintenance or adjustments to effect pedals or effect pedal accessories (power supply units, signal junction units, etc) which may not require frequent access.

[0032] Referring to FIG. 4 and FIG. 5, the upper platform 106 is connected to the lower platform 108 by a pivoting front rocker 112 and a pivoting rear rocker, forming a four-bar linkage. In the embodiment shown, the rear rocker is an assembly of a back wall 110 and an extension 114 of the back wall which allows for a connection with the upper platform 106 at a pivot point 122 which is suitable for the desired motion of the four-bar linkage. The upper platform 106 has a similar extension 116. The pivot joint 124 between the rear rocker assembly 110, 114 and the lower platform 108 may consist of a hinge which is limited in its range of motion and may determine the stopping positions of the four-bar linkage. In other embodiments, any joint between a rocker and a platform may consist of a similar mechanical component with a limited range of motion. The shape of the rockers or platforms and their extensions may also determine the stopping positions of the linkage as they engage with other components of the linkage during certain ranges of motion. For example, in FIG. 4 the front rocker 112 has a bent shape which encounters the lower platform 108 at the extent of its determined forward range. A protrusion 130 from the side wall 104 may also be used to establish a limit to the range of one or more of the rockers.

[0033] Although FIG. 4 shows the linkage assembly on one side of the pedalboard, the embodiment shown is understood to also have a mirrored linkage on the opposite side. The back wall 110 may be a shared component between the mirrored linkages which adds stability to the structure while in each position and while transitioning between positions.

[0034] The front rocker 112 may be removably attached to the upper platform 106 by a joint 120 allowing the upper platform 106 to become temporarily detached from the front rocker 112 in order to tilt upwards and reveal the lower platform 108 or the underside of the upper platform 106. This connection may be made by a spring latch, a magnetic latch, or any other suitable latch. The connection point 120 may be extended below the upper platform 106 in a fashion similar to the rear deck extension 116 as necessary to produce the desired mechanics of the four-bar linkage.

[0035] In the embodiment shown, the lower platform 108 has fixed side walls 104 which act as extensions of the lower platform 108 and provides a suitable pivoting joint location 118 with the front rocker 112. There is also a front wall 102 which provides structural stability and, along with the side walls 104 and back wall 110, acts as a protective case which encloses the effect pedals mounted on the lower platform 108. Some or all of these walls may be omitted from other embodiments of the pedalboard.

[0036] The back wall 110 and the underside of the upper platform 106 may be treated as additional mounting surfaces for suitably sized effect pedals or accessories. In the embodiment shown, the back wall 110 is a component of the four-bar linkage and as such, any pedals or accessories mounted to the back wall 110 will change in orientation as the pedalboard transitions between positions. In the case of power supply units this is particularly advantageous, as the increased physical distance between the power supply unit and other pedals or accessories can reduce unwanted electromagnetic interference from the power supply unit. In the case where the power supply unit is mounted to the underside of the upper platform 106, a similar advantage is achieved due to the increase in physical distance between the power supply unit and the pedals mounted to the lower platform 108 while the pedalboard is in an open position.

[0037] The open orientation of the back wall 110 also provides access for power cables and signal cables to pass into the pedalboard when in an open position (as seen in FIG. 5). Advantageously, when the pedalboard is positioned for storage or transportation (as seen in FIG. 4), this access is automatically closed as the back wall moves to a vertical position and aligns with the side walls 104. This contributes to the protection of the pedals and accessories inside the pedalboard, especially when paired with a suitable mated removable lid. The pedalboard may also contain separate passages 132 in the side or front walls allowing for the loose passage of power or signal cables. Connection jacks for such cables may also be permanently mounted into the walls.

[0038] In order to prevent unintended transitions between pedalboard positions a locking mechanism may be employed which temporarily attaches components of the linkage together in a fashion which inhibits motion. For example, a latch might be employed which joins the back wall 110 to the side wall 104.

[0039] In regards to FIG. 6 and FIG. 7, the shape of the upper platform 106 may be modified to accommodate the use of large pedals 128. The upper platform 106 may contain holes or passages 126 for the passage of power or signal cables to the lower platform 108 and vice versa.
