Definitions
- the present invention relates, in general, door latches and, in particular, to an infant incubator port assembly.
- Latches on infant incubator ports should possess the following features:
- infant incubators in use at the present time have the first three above features but lack the fourth.
- the canopy of an infant incubator typically is fabricated from acrylic sheet or similar material which has a hard, reflective surface. Sound which is produced on the surface of the canopy is not attenuated but rather reflected within the canopy. Peak sound levels of 90 dbA and higher have been measured within certain incubators when a door is closed. Such noise can startle and cause discomfort to an infant in the incubator.
- a door assembly constructed in accordance with the present invention, includes a support structure having an opening and a door mounted on the support structure for movement of the door between open and closed positions of the door. Means are provided for urging the door to move to its open position. Also included are latching means between the door and the support structure for closing the door and locking the door in its closed position.
- the latching means include an impact absorbing member and a latch member engaged by the impacting absorbing member as the two are urged into engagement.
- the latch member has (i) a contact surface engaged by contact of the impact absorbing member as the door moves to the closed position and (ii) a detent at an end of the contact surface which, when reached by the impact absorbing member as the door moves to the closed position, receives the impact absorbing member to lock the impact absorbing member in the detent and lock the door in its closed position.
- the latching means also include means for disengaging the impact absorbing member and the latch member to release the impact absorbing member from the detent and permit the door to move to its open position.
- FIG. 1 shows an infant incubator canopy 10 having a pair of door assemblies 12 and 14 constructed in accordance with the present invention installed in a front door panel 16 which serves as a support structure for the door assemblies.
- Door assemblies 12 and 14 each have a door 18 and 20, respectively, which cover openings in panel 16 when the doors are closed. Doors 18 and 20 are mounted on panel 16 for pivotal movement about axes defined by a pair of hinges 22 and 24, respectively.
- a torsion spring 26 is positioned between hinge 24 and door 20. Spring 26 urges door 20 to pivot in a first direction to the open position of the door. A similar torsion spring is provided between hinge 22 and door 18.
- a door assembly constructed in accordance with the present invention, also includes a latching mechanism between door 18 and support structure 16 for closing the door and locking the door in its closed position.
- the latching mechanism includes an impact absorbing member in the form of an elastomeric roller 28 mounted on the edge of door 18 opposite from hinge 22. Roller 28 is arranged for rotational movement about an axis parallel to the axis of hinge 22.
- the latching mechanism also includes a latch member 30 mounted on panel 16 at the side of the opening in panel 16 opposite from hinge 22.
- Latch member 30 is mounted for pivotal movement about an axis parallel to the pivot axis of hinge 22 and the rotation axis of roller 28.
- latch member 30 has a contact surface 30a and a detent 30b at the end of contact surface 30a.
- Contact surface 30a is an inclined surface which is engaged by rolling contact of roller 28 to pivot the latch member in a first direction, indicated by an arrow 32 in Figure 3A, to a position such as shown in Figure 3B, as door 18 pivots against torsion spring 26 toward the closed position of the door.
- a spring 34 urges latch member 30 and roller 28 into engagement by pivoting the latch member in a second direction opposite to the direction indicated by arrow 32.
- Spring 34 extends between the closed end of a bore 36 in latch member 30 and a pin 38 fitted within bore 36 for sliding movement within the bore and bearing against panel 16.
- spring 34 is compressed.
- roller 28 reaches detent 30b, so that latch member 30 is free to pivot in the opposite direction, spring 34 is permitted to expand and causes the latch member to pass over roller 28 and lock the roller in detent 30b. This in turn locks door 18 in its closed position.
- the latching mechanism also includes means for disengaging roller 28 and latch member 30 to release the roller from detent 30b and permit door 18 to pivot to its open position.
- Such means can include a handle 30C formed as a part of latch member 30. As handle 30C is pushed toward panel 16, latch member 30 pivots in the direction of arrow 32 shown in Figure 3A. Such movement of the latch member permits release of roller 28 from detent 30b as torsion spring 26 urges door 18 to move to its open position.
- Elastomeric roller 28 is provided to address the first two events. This roller absorbs energy which would otherwise be converted into sound and it shifts the sound that is produced to a lower frequency to which the human ear is less sensitive.
- roller 28 forces latch member 30 to pivot further and further from its initial position.
- the increasing engagement of latch member 30 and roller 28, namely event (2), is a rolling contact rather than a sliding contact which produces very low noise with a soft roller.
- latch member 30 moves in an opposite direction to its final, locking position, its motion toward panel 16 is stopped by another elastomeric piece, namely a ring 40, rather than the hard surface of the latch member itself. This reduces the sound produced by event (3).
- a door assembly constructed in accordance with the present invention, is latched such that the door cannot be pushed open from inside the incubator because the pivot point of latch member is directly below the contact point between door 18 and the latch member when the door is in the closed position. Also, because of the rolling contact between roller 28 and latch member 30, latching is never partial. The spring loaded latch member will either close over roller 28, latching door 18, or torsion spring 26 will pivot the door to its open position. Lastly, handle 30C is large enough to be pushed by the user's elbow to open the door.
- the present invention can be applied to doors mounted for sliding, linear movement as they are opened and closed.
