    Abstract: A door closer includes: a cylinder secured on a door frame and having a cylinder head formed on a proximal end of the cylinder; a main value and a check valve respectively formed on the cylinder head to control the air in-and-out volume through the valves for lightly opening the door; a piston secured to a rod member slidably reciprocating within the cylinder with the rod member secured to a door; a restoring spring secured between the cylinder head and the rod member for normally resiliently restoring the rod member and the piston towards the cylinder head in order to close the door to the door frame normally as restored by the restoring spring; and at least a buffer member secured between the cylinder head and the piston so as to dampen the inertia force of the closing door to eliminate the noise or damage thus possibly caused.

    Abstract: A bracket is provided for use in installing door hardware on a support surface. The bracket comprises a rigid member having a longitudinal axis, a front surface, a substantially planar rear surface for engaging the support surface, and a peripheral edge extending between and joining the front and rear surfaces. A spirit bubble level is disposed on the rigid member such that the rigid member can be oriented relative to a horizontal line or a vertical line, the level having the bubble centered only when the level is horizontal or vertical. At least a portion of the peripheral edge of the rigid member provides a mounting surface for the door hardware when the rigid member is secured to the support surface.

    Abstract translation: 提供了一种用于将门硬件安装在支撑表面上的支架。 支架包括具有纵向轴线的刚性构件，前表面，用于接合支撑表面的基本平坦的后表面，以及在前表面和后表面之间延伸并在其之间连接的周边边缘。 精神气泡水平设置在刚性构件上，使得刚性构件可以相对于水平线或垂直线定向，所述水平仅当水平面为水平或垂直时才具有气泡中心。 当刚性构件固定到支撑表面时，刚性构件的周缘的至少一部分提供用于门硬件的安装表面。
