Description

I. RECLINER CHAIR WITH OBJECT SENSOR AND ALERT

11. BACKGROUND OF THE INVENTION

1. Field of the Invention.

[001] The present invention relates to recliner chairs and, more particularly, to a recliner chair with object sensor and alert.

2. Description of the Related Art.

[002] Several designs for recliner chairs have been designed in the past. None of them, however, include an object sensor located on the bottom of the foot rest to detect a pet, a person or an object under the rest.

[003] Applicant believes that a related reference corresponds to U.S. patent No. 4,660,883 issued for a safety platform placed under the foot rest of a reclining chair to prevent a person or animal from being injured if they are under the foot rest when it closes. Applicant believes that another related reference corresponds to U.S. patent No. 3,083,996 issued for a reclining chair with elevating foot rest. None of these references, however, teach of a recliner chair with object sensor and alert that can detect a pet, a person or an object under the foot rest when opened and will emit an alert to prevent the foot rest from closing on the object.

[004] Other documents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of

these patents suggest the novel features of the present invention.

Ill SUMMARY OF THE INVENTION

[005] It is one of the objects of the present invention to provide a recliner chair with object sensor and alert that includes a sensor to detect toddlers, pets or objects under the foot rest.

[006] It is another object of this invention to provide a recliner chair with object sensor and alert that emits an alarm to alert that a pet, a person or an object is under the foot rest when the foot rest is elevated.

[007] It is still another object of the present invention to provide a recliner chair with object sensor and alert that prevents a user sat on the chair from closing the foot rest.

[008] It is yet another object of this invention to provide such a device that is inexpensive to implement and maintain while retaining its effectiveness.

[009] Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.
