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.
Claims20
An assist apparatus, the apparatus comprising:
- a first door activation device;
- a second door activation device operatively coupled to the first door activation device;
- and
- an assist component operatively coupled to the first door activation device;
- wherein the first door activation device and the second door activation device are configured to be operatively coupled to a door to allow for rotation of at least a portion of the first door activation device and the second door activation device;
- wherein the assist component aids in opening or closing the door;
- wherein when the first door activation device is activated the first door activation device rotates independently from the second door activation device;
- and
- wherein when the second door activation device is activated the first door activation device rotates together with the second door activation device.
A door system, the door system comprising:
- a track assembly;
- a sliding door operatively coupled to the track assembly;
- an assist apparatus comprising:
- a first door activation device;
- a second door activation device operatively coupled to the first door activation device;
- and
- an assist component operatively coupled to the first door activation device;
- wherein the first door activation device and the second door activation device are operatively coupled to the sliding door allowing for rotation of at least a portion of the first door activation device and the second door activation device;
- and
- wherein the assist component aids in opening or closing the sliding door by engaging an adjacent surface located apart from the sliding door;
- wherein when the first door activation device is activated the first door activation device rotates independently from the second door activation device;
- and
- wherein when the second door activation device is activated the first door activation device rotates together with the second door activation device.
A method of using a sliding door system, the method comprising:
- activating a first door activation device or a second door activation device operatively coupled to the first door activation device from a resting position to one or more engaging positions, wherein the first door activation device and the second door activation device are operatively coupled to a sliding door, wherein when the first door activation device is activated the first door activation device rotates independently from the second door activation device, and wherein when the second door activation device is activated the first door activation device rotates together with the second door activation device;
- engaging, in response to the activating of the first door activation device or the second door activation device, an assist component operatively coupled to the first door activation device 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.
