Cheyenne Hutchinson. Door Handles. September 16th , 2018.
Lever operated door handles are very popular in European homes, as they are easier to use. This makes them suitable for elderly people, as this design of these handles does not require a tight grip; unlike the door knob, which may slip from the user's hand. The door knob is more commonly used in the United States because of its practicality and dual functions: it functions as a door latching mechanism and a lock at the same time. However, U.S. commercial and business establishments have woken up to the practicality of using the lever style of door handles. Aside from easy operation, they are less likely to jam. Further, the lever operated handles are more robust, and can withstand constant use.
The handle, as it exists today, is a relatively new invention dating to the mid-19th century, with the first American patent dated in the 1850s. Handles and knobs experienced a massive period of growth and development throughout the Victorian Era (1830-1900). Thousands of variations on the theme of the door handle, in combination with modern production methods, made door handles accessible to virtually everyone. Latches faded in popularity and use, relegated to service in barns and similar outbuildings where their simplicity and design function trumps external appearance. These handles today serve multiple functions. Among these functions, may include lock and key mechanisms, electronic locks, push button access that is either mechanical or electronic, high-security features and many other applications other than a simple push-pull device to open or close a door.
While different types of door handles are designed with unique components, the average handle has basic components. For instance, in addition to the knob top, which is the large knob that you would actually grab hold of to turn, handles are made with a spindle, shank, and knob rose. The knob rose is a round washer or plate used to form a socket. This piece is adapted so it can be attached to the actual door. Then, there is that spindle, which is the thin piece to which the handle attaches. The shank is the stem that projects from the door handle. Within the shank is a hole in which the spindle would be placed. For functionality, the door handle would be attached so the metal shaft can turn the latch to open the door.
