ORBITAL SANDER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240009795 titled 'ORBITAL SANDER

Simplified Explanation

The abstract describes an orbital sander that consists of a housing and a drive unit. The drive unit includes an electric motor and a drive shaft. The motor has a motor output shaft that defines a rotational axis. The drive shaft is coupled to the motor output shaft for co-rotation around the rotational axis. The drive shaft has an eccentric portion that orbits around the rotational axis. A sanding pad is coupled to the eccentric portion. A handle extends from the housing at an oblique angle relative to the rotational axis. A battery pack is coupled to the handle to provide power to the electric motor. The design of the orbital sander allows for easy grasping by users.

• The orbital sander comprises a housing and a drive unit.
• The drive unit includes an electric motor and a drive shaft.
• The motor output shaft defines a rotational axis.
• The drive shaft is coupled to the motor output shaft for co-rotation.
• The drive shaft has an eccentric portion that orbits around the rotational axis.
• A sanding pad is attached to the eccentric portion.
• The handle extends from the housing at an oblique angle.
• A battery pack is connected to the handle to power the electric motor.
• The design of the orbital sander allows for convenient grasping by users.

Potential Applications

• Woodworking: The orbital sander can be used for sanding wooden surfaces, such as furniture, cabinets, and flooring.
• Metalworking: It can be used for smoothing and finishing metal surfaces, such as automotive parts or metal furniture.
• DIY Projects: The orbital sander is suitable for various DIY projects that involve sanding, such as refinishing old furniture or preparing surfaces for painting.

Problems Solved

• Improved Ergonomics: The oblique angle of the handle allows for a more comfortable grip and reduces strain on the user's wrist and arm.
• Efficient Sanding: The eccentric motion of the sanding pad ensures even and consistent sanding across the surface, reducing the need for manual adjustments.
• Portable Power: The battery pack provides cordless operation, allowing for greater mobility and convenience during sanding tasks.

Benefits

• User-Friendly Design: The orbital sander is easy to grasp and maneuver, making it suitable for both professionals and DIY enthusiasts.
• Time and Effort Saving: The efficient sanding action and ergonomic design contribute to faster and more efficient sanding, reducing overall project time.
• Versatility: The orbital sander can be used on various materials and surfaces, making it a versatile tool for different applications.

Original Abstract Submitted

an orbital sander () comprises a housing () and a drive unit () in the housing (). the drive unit () includes an electric motor () and a drive shaft (). the electric motor () has a motor output shaft defining a rotational axis (). the drive shaft () is coupled for co-rotation with the motor output shaft about the rotational axis (). the drive shaft () has an eccentric portion () configured to orbit about the rotational axis (). a sanding pad () is coupled to the eccentric portion (). a handle () extends from the housing () at an oblique angle greater than degrees relative to the rotational axis (). a battery pack () is coupled to the handle () for providing power to the electric motor (). the orbital sander () is convenient for users to grasp.
