The invention generally relates to a ride-on machine having internal workings, and more particularly to a ride-on power trowel having internal workings.
Power trowels involve a great number of moving parts. Parts such as belts, conduits, engines, batteries, and the like are often supported by the frame of the trowel, but with such parts located in an internal area of the trowel. Positioning such parts in an internal area of the trowel reduces the risk that an operator will come into unintended contact with these moving, hot, or otherwise dangerous parts. It further allows the external parts of the trowel to shield the unsightly internal parts from observers. However, locating these internal workings inside the trowel makes it more difficult to provide needed maintenance to the trowel. Often significant sections of the exterior of the trowel must be physically disconnected from the rest of the trowel so as to allow a mechanic access to the internal workings. Such disassembly often requires a significant amount of time, skill, tooling, and effort to accomplish. Further, requiring workers to move heavy parts of a trowel presents opportunities for accidents. Also, every part that must be disconnected from the trowel to allow for routine maintenance presents a risk for a lost part that will need to be replaced. Still further, repeated manipulation of hardware, such as nuts, screws, and the like, can lead to stripping or other wear of the hardware, leading to increased need to replace such hardware.
The present unfolding ride-on power trowel allows ready access to the internal workings of a power trowel without substantial disassembly of the trowel. The unfolding ride-on power trowel includes a frame that supports a front cover and a back cover. The internal workings of the trowel, such as the engine, are also supported by the frame of the trowel. A right side cover is pivotally connected to the frame and can be pivoted between a right open configuration and a right closed configuration. A left side cover is also pivotally connected to the frame and can be pivoted between a left open configuration and a left closed configuration. Additionally, as the unfolding ride-on power trowel is to be operated by an operator, the trowel further includes a seat supported by a seat platform. In some embodiments, the seat platform is pivotally connected to the front cover. In other embodiments, the seat platform is pivotally connected to the back cover. In either regard, the seat platform can be pivoted between a seat open configuration and a seat closed configuration. When the right side cover is in the right closed configuration, the left side cover is in the left closed configuration, and the seat platform is in the seat closed configuration, the internal workings of the unfolding ride-on power trowel are not readily accessible. Accessibility is made possible by pivoting any of the right side cover, the left side cover, the seat platform, or any combination thereof to its respective open position. In some embodiments, the accessibility of the internal workings is made possible without any disassembly of the unfolding-power trowel.
In other embodiments, side gratings are removably connected with the right side cover and the left side cover. In these embodiments, preferably, the respective side grating is removed before the right side cover is transitioned to the right open configuration or the left side cover is transitioned to the left open configuration. Preferably, the removal of a side grating is accomplished by disconnecting only one connection of hardware. Thus, even in this embodiment, no substantial disassembly of the unfolding ride-on power trowel is necessary to gain ready access to the internal workings of the trowel.
The purpose of the Summary is to enable the public, and especially the scientists, engineers, and practitioners in the art who are not familiar with patent or legal terms or phraseology to determine quickly, from a cursory inspection, the nature and essence of the technical disclosure of the application. The Summary is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
Still other features and advantages of the claimed trowel will become readily apparent to those skilled in the art from the following detailed description describing preferred embodiments of the trowel, simply by way of illustration of the best mode contemplated by carrying out the trowel. As will be realized, the trowel is capable of modification in various obvious respects all without departing from the invention. Accordingly, the drawings and description of the preferred embodiments are to be regarded as illustrative, and not restrictive.
While the unfolding ride-on power trowel is susceptible of various modifications and alternative constructions, certain illustrated embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined herein.
In the following description and in the figures, like elements are identified with like reference numerals. The use of “e.g.,” “etc,” and “or” indicates non-exclusive alternatives without limitation unless otherwise noted. The use of “including” means “including, but not limited to,” unless otherwise noted.
As shown in the figures, for purposes of illustration, the unfolding ride-on power trowel comprises a ride-on power trowel, the internal workings of which are made readily accessible simply by selectively pivoting a right side cover to a right open configuration, a left side cover to a left open configuration, and/or a seat platform to a seat open configuration.

The left side cover 24 also includes pivot connections 28 (shown in
According to the preferred embodiment, a left side grating 20 (shown in
Further, the left side grating 20 is likewise configured to be removably attachable to the left side cover 24 via hardware such as a clip 52, washer 54, and screw 56. It should be noted that while
The seat platform 40 of the unfolding ride-on power trowel 10 is additionally pivotally connected. More specifically, in the depicted embodiment, it is pivotally connected to the front cover 32 via a pivot bar 34. That is, as shown in
While, according to the first embodiment, the seat platform 40 is pivotally connected to the front cover 32, in other embodiments, the seat platform 40 is pivotally connected to the back cover 36. The back cover 36, as shown in
Also, in some embodiments, such as that shown in
Likewise, in embodiments such as that shown in
Notably, when the right side cover 14 is in the right closed configuration, the left side cover 24 is in the left closed configuration, and the seat platform 40 is in the seat closed configuration (
While, according to the first preferred embodiment, the open configuration of the unfolding ride-on power trowel 10 includes the right side cover 14 being in the right open configuration, the left side cover 24 being in the left open configuration, and the seat platform 40 being in the seat open configuration, in other embodiments, the unfolding ride-on power trowel 10 is configured to accommodate transitioning the right side cover 14 to the right open configuration while the left side cover 24 remains in the left closed configuration and the seat platform 40 remains in the seat closed configuration. This allows ready access to the right-most of the internal workings 50.
Similarly, in some embodiments, the unfolding ride-on power trowel 10 is configured to accommodate transitioning the left side cover 24 to the left open configuration while the right side cover 14 remains in the right closed configuration and the seat platform 40 remains in the seat closed configuration. This allows ready access to the left-most of the internal workings 50.
Still further, in some embodiments, the unfolding ride-on power trowel 10 is configured to accommodate transitioning the seat platform 40 to the seat open configuration while the right side cover 14 remains in the right closed configuration and the left side cover 24 remains in the left closed configuration. This allows ready access to the upper-most of the internal workings 50.
While there is shown and described the present preferred embodiment of the unfolding ride-on power trowel, it is to be distinctly understood that this ride-on trowel is not limited thereto but may be variously embodied to practice within the scope of this disclosure. From the foregoing description, it will be apparent that various changes may be made without departing from the spirit and scope of the invention as defined by this disclosure.
Still other features and advantages of the present invention will become readily apparent to those skilled in this art from the forgoing detailed description describing preferred embodiments of the invention, simply by way of illustration of the best mode contemplated by carrying out the invention. As will be realized, the unfolding ride-on power trowel is capable of modification in various obvious respects all without departing from the invention. For example, in some embodiments, each of the side gratings 20 are pivotally connected to the corresponding right side cover 14 or left side cover 24, such that before transitioning the right side cover 14 between the right closed configuration and the right open configuration, the right-most side grating 20 is pivotally extended away from the frame 12 so that the right side cover 14 and the right-most side grating 20 lay in an almost 180-degree relation to one another when said right side cover 14 is in the right open configuration. Similarly, in such an embodiment, the left-most side grating 20 is pivotally connected to the left side cover 24, such that, before transitioning the left side cover 24 between the left closed configuration and the left open configuration, the left-most side grating 20 is pivotally extended away from the frame 12 so that the left side cover 24 and the left-most side grating 20 lay in an almost 180-degree relation to one another when said left side cover 24 is in the left open configuration. In such an embodiment, no part of the unfolding ride-on power trowel 10 need be disconnected completely from the power trowel 10 in order to gain ready access to the internal workings 50 of the machine 10.
Because the unfolding ride-on power trowel may be modified in various obvious ways while still being within the scope of the invention, the drawings and description of the preferred embodiments are to be regarded as illustrative in nature, and not as restrictive in nature.
