Abstract
An assist apparatus utilized within a door system to aid in opening the door. The assist apparatus may include one or more door activation devices (e.g., a first door activation device and a second door activation device, such as pulls on opposite sides of a sliding door) that can rotate around a pivot location. Moreover, the assist apparatus may further include one or more assist components operatively coupled to the one or more door activation devices. The door activation device(s) are configured to be operatively coupled to a sliding door and allow for rotation of at least a portion of the door activation device. The assist component(s) of the door activation device(s) aid in opening or closing the sliding door by engaging a door frame, wall, or the like as the door activation device is rotated.

An assist apparatus, the apparatus comprising:
- one or more door activation devices;
- and
- an assist component operatively coupled to a door activation device of the one or more door activation devices;
- wherein at least one door activation device of the one or more door activation devices is configured to be operatively coupled to a door to allow for rotation of at least a portion of the door activation device;
- and
- wherein the assist component of the door activation device aids in opening or closing the door.
A door system, the door system comprising:
- a track assembly;
- a sliding door operatively coupled to the track assembly;
- an assist apparatus comprising:
- one or more door activation devices;
- and
- an assist component operatively coupled to a door activation device of the one or more door activation devices;
- wherein at least the door activation device of the one or more door activation devices is operatively coupled to the sliding door allowing for rotation of at least a portion of the door activation device;
- and
- wherein the assist component of the door activation device aids in opening or closing the sliding door by engaging an adjacent surface located apart from the sliding door.
A method of using a sliding door system, the method comprising:
- activating one or more door activation devices from a resting position to one or more engaging positions, wherein the one or more door activation devices are operatively coupled to a sliding door;
- engaging, in response to the activating the one or more door activation devices, an assist component operatively coupled to the one or more door activation devices with an adjacent surface located apart from the sliding door;
- and
- moving the sliding door as the assist component pushes against the surface adjacent the sliding door when a door activation force overcomes an open force of the sliding door.
