ABSTRACT:

FIELD OF THE INVENTION
This invention relates generally to indicators and, more particularly, to electronic position indicators for the gate of a crib.
BACKGROUND OF THE INVENTION
Most baby cribs comprise a mattress located within a bed frame having four sides, with each side comprising vertical bars positioned between a top molding and a bottom molding. Two opposing sides are vertically displaceable, known as a crib gate, in either a raised (closed) condition or in a lowered (open) position. Lowering the gate is accomplished by displacing a footbar (located at the bottom and just under the bottom molding) which disengages a bottom molding catch from the footbar and then allows the gate to drop downward. Raising the gate is accomplished by simply lifting the gate is upwards until the bottom molding catch re-engages the footbar, thereby locking the gate in a raised position.
In most instances, the parent or infant-caretaker will be holding or rocking the baby to sleep. When the parent or infant-caretaker is ready to place the baby on the mattress, the gate is lowered as discussed previously. Usually, the parent or infant caretaker is so focused on positioning the infant on the mattress without waking the infant that frequently the parent or infant-caretaker forgets to raise the gate after the infant is placed on the mattress. The result is that the infant is left in a crib with the gate down. If the infant is old enough to roll and raise himself/herself, the infant could fall out of the crib at a later time because the crib gate remains in an open condition.
Moreover, a recent study conducted by a Temple University researcher has recommended increasing the side heights of cribs to reduce the number of falls from cribs. If this recommendation is followed, the opening and closing of the crib gate by the parent/caregiver should occur more often since raising the height of the crib sides makes it more difficult to place or lift a toddler from the crib without opening the gate. As a result, this increases the chances that a parent/caregiver may walk away from a crib with the toddler inside and with the crib gate left open.
The following U.S. patents disclose some form of indication or warning in association with a baby crib or bed.
U.S. Pat. No. 2,734,104 (Gollhofer) discloses an alarm for alerting an attendant that the crib gate is in a down position.
U.S. Pat. No. 4,231,030 (Weiss) discloses a safety device for a crib that provides an indicating light or an alarm at the crib to alert a person to the fact that the crib gate is in a down position.
U.S. Pat. No. 4,951,032 (Langsam) discloses a crib rail safety monitor that utilizes a weight sensor for detecting the presence of a child in the crib and an ultrasonic motion detector or infrared temperature sensor for detecting the presence of an attendant at the crib in order to provide an indication or alarm at the crib that the crib gate is down when the child is in the crib and is unattended.
U.S. Pat. No. 5,057,819 (Valenti) discloses a safety cushion device that is positioned on the floor adjacent the baby crib for cushioning the fall of a child and an alarm for alerting an adult of such a fall.
U.S. Pat. No. 5,291,181 (DePonte) discloses a wet bed alarm and temperature monitoring system for detecting urine on the bed and the temperature of a person lying on the bed and for supplying a remote annunciator panel with such information.
U.S. Pat. No. 5,629,683 (Slomowitz et al.), whose entire disclosure is incorporated by reference herein, discloses an automatic crib gate indicator that utilizes a remote-enabling means to enable a crib gate sensor that detects the open condition of the crib gate and then transmits a signal to a remotely located indicator.
U.S. Pat. No. 5,757,274 (Slomowitz et al.), whose entire disclosure is incorporated by reference herein, discloses an automatic crib gate indicator that utilizes a crib gate sensor, for detecting the open condition of the crib gate, that is integrated with a baby monitoring system.
U.S. Pat. No. 6,225,913 (Slomowitz et al.) discloses an automatic crib gate indicator that utilizes a crib gate sensor for detecting the open condition of the crib gate.
However, there remains a need to provide a more durable crib gate sensor for a crib gate position indicator that provides the parent or infant-caretaker with an automatic remotely-located indication or warning of the crib gate being left in an open condition.
SUMMARY OF THE INVENTION
A gate sensor for use with a baby crib having a displaceable gate (e.g., a vertically-displaceable gate, a rotatably-displaceable gate, etc.) that can be moved into an open or a closed position. The gate sensor detects the open condition of the displaceable gate and transmits a wireless signal to a remotely-located indicator (e.g., a dedicated remote indicator, a parent unit of a baby monitoring system which includes a “crib gate open indicator”). The gate sensor comprises: a first portion containing a transmitter coupled to a crib; and a second portion coupled to the displaceable gate wherein the second portion interacts (e.g., by contact, or non-contact interaction) with the first portion when the displaceable gate is moved into the open position to cause the first portion to transmit the wireless signal.
A gate sensor for use with a baby crib having a displaceable gate that can be moved into an open or a closed position. The gate sensor detects the open condition of the displaceable gate and transmits a wireless signal to a remotely-located indicator (e.g., a dedicated remote indicator, a parent unit of a baby monitoring system which includes a “crib gate open indicator”). The gate sensor comprises: a first portion containing a transmitter coupled to the displaceable gate; and a second portion coupled to the crib wherein the second portion interacts (e.g., by contact, or non-contact interaction) with the first portion when the displaceable gate is moved into the open position to cause the first portion to transmit the wireless signal.

The gate sensor detects the open condition of the displaceable gate and transmits a wireless signal to a remotely-located indicator (e.g., a dedicated remote indicator, a parent unit of a baby monitoring system which includes a “crib gate open indicator”). The gate sensor comprises: a housing including a pair of downwardly-directed members extending from each end of a central portion, and wherein the central portion is disposed on a horizontal support surface located at a lower part of the crib. The housing includes: a microphone and transmitter, for detecting the sounds of the infant or toddler placed in the crib and for generating a wireless signal representative of the sounds; a switch interfaced with the displaceable gate and electrically coupled to a signal generator to a power source whenever the displaceable gate is in an open condition to form a crib gate open condition signal; and wherein the signal generator has an output coupled to the transmitter for incorporating the crib gate open condition signal into the wireless signal.
A method for detecting the open condition of a displaceable gate (e.g., a vertically-displaceable gate, a rotatably-displaceable gate, etc.) of a crib. The method comprises the steps of: coupling a first member comprising a transmitter to the crib; coupling a second member to the displaceable gate; and wherein the first member and the second member interact (e.g., by contact, or non-contact interaction) with each other to cause the transmitter to transmit a wireless signal to a remote indicator (e.g., a dedicated remote indicator, a parent unit of a baby monitoring system which includes a “crib gate open indicator”) whenever the displaceable gate is opened.
A method for detecting the open condition of a displaceable gate (e.g., a vertically-displaceable gate, a rotatably-displaceable gate, etc.) of a crib. The method comprises the steps of
