ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates generally to a device that attaches to a telephone for the purpose of lifting up the receiver end of a telephone handset (hook-switching).
2. Description of the Prior Art
Many of the newest telephone systems that are coming out on the market have what is called electronic hook-switching. This is basically a button, that when pressed, will give a dial tone for a telephone headset. This is a very convenient option for people who use telephone headsets, but the problem still remains that there are literally millions of telephones on the market that do not have this option.
Until now, the only option that people have had to alleviate this problem is to physically pick up the handset every time the telephone rings, and place the headset off to the side of the telephone base. This procedure is time and space consuming.
Another method that is commonly used when getting a dial tone, is to balance the telephone handset just up and to the side of the telephone's hook-switch. The major problem with this solution is that if accidently bumped or moved, the handset will fall back into place and one will hang up the line.
The present invention overcomes the prior art practices by providing a mechanical handset lift for lifting the receiver end of a telephone handset off the hook-switch and pivoting the handset about the microphone end, but leaving the handset centrally positioned over and about the telephone body.
SUMMARY OF THE INVENTION
The general purpose of the present invention is to provide a mechanical device for lifting the receiver end of a telephone handset off the telephone hook-switch to allow electrical operation of a remote handset receiver/mouthpiece while still leaving the handset placed over and about the telephone base unit.
According to one object of the present invention, there is provided a vertically oriented base for mounting to the side of a telephone base. A moveable pivot shaft extends through an upper region of the vertically oriented base end, which includes a lift rod secured to one end of the pivot shaft and a lift rod lever handle secured to the opposite end of the pivot shaft. A stop shaft limits the over center travel of the lift rod lever handle and the lift rod to allow on hook or off hook positioning of a telephone handset receiver.
According to an alternate embodiment of the present invention, there is provided a vertical base member with a lift rod and lift lever secured about the base member in positive locked alignment and also having rotational stops aligned on a surface of the vertical base member.
One significant aspect and feature of the present invention is mechanical handset lift that will mechanically lift up the receiver end of a telephone handset off the hook-switch so that a dial tone may be obtained for the telephone headset in use.
Another significant aspect and feature of the present invention is a mechanical handset lift which will lift the receiver end of a telephone handset off the hook-switch so as to allow a user to use either the telephone handset or a telephone headset.
A further significant aspect and feature of the present invention is a mechanical handset lift which will lift the receiver end of a telephone handset off the hook-switch and which will result in the environment on a person's desk being less cluttered due to the absence of a telephone handset lying off to the side of the telephone base while the telephone handset is in use.
Yet another significant aspect and feature of the present invention is a mechanical handset lift that will mechanically lift up the receiver end of a telephone handset in such a manner that will greatly increase the chances of not accidentally hanging up the telephone while a telephone headset is in use.
Another significant aspect and feature of the present invention is a lift rod and lift rod handle in positive angular engagement with each other about a base unit.
Another significant aspect and feature of the present invention is stops which define rotational movement of the lift rod and lift rod handle with respect to the base of a telephone.
Having thus described the embodiments of the present invention, it is the principal object hereof to provide a mechanical handset lift.
The present invention relates to a mechanical handset lift device that will enable the telephone user to enable and disable the telephone's hook-switch capabilities without the inconvenience of picking up the telephone and placing it on the desk. Currently, the only means to do this is by placing the telephone handset on and off the hook-switch. The problems that arrive from this method are 1) one has to physically pick up the handset every time the telephone rings, 2) one has to lay the handset on the desk (for many people this takes up just too much room), 3) if the telephone allows one to balance the handset off to the right side of the hook switch, one may bump the telephone, and accidentally hang up.
The invention uses the handset's own mold to accomplish the goal of hook-switching, and allows the handset to be used as well. The present invention also creates an environment where it is virtually impossible to accidently hand up the telephone. This is a very common problem when the telephone is balanced to the side of the hook-switch.
It is an object of the present invention to provide a device that will enable a telephone handset operator to use both the telephone handset or headset conveniently, without the problems that are currently plaguing the telephone headset industry.
