One hand automatic closing mailbox door

Abstract

The present invention is an improved door for rural mailboxes, comprising of a frame and door rotating inward and vertically downward, or just vertically downward, allowing access to the mailbox for depositing or removal of mail in one motion. The frame and door made of wood, metal, plastic, rubber or other materials can be made as part of a new mailbox or made as a complete assembly to be added to an existing mailbox. The frame comprises channels with springs to hold door closed. The door having pins or one rod horizontally mounted on the door or held on each side of the door by collars and springs also used to hold the door closed or move the door vertically and inward as it moves toward the bottom of the mailbox. The pins extend into the channels on the frame.

DETAILED DESCRIPTION

(10) Referring to FIGS. 1A-4C and 5: a self-closing door 100 for a mailbox 200 has a horizontal hinge pin/pivot 104 near the top of a vertically hanging door 102, and side tracks 106 holding both ends of the pin 104. The tracks restrict the pin and the attached door to pivoting on axis, as shown in FIG. 2B and to vertical movement along the track, as shown in FIG. 2C. A spring 108 biases the pin 104 up against the top of the track 106 where the door 102 is positioned to cover the mailbox opening. Gravity and optionally a spring, e.g., 112 bias the door to a closed position that covers the opening of box 200. The door 102 has a top part 102a above the pivot pin 104 and a bottom part 102b there below.

(11) To operate the self closing door 100 for depositing mail into the box 200, the inventive method steps are: 1a holding mail in hand, push in on top part 102a of the door i.e., above the hinge pin 104, enough to be able to . . . 1b push downward and/or further inward to create a large enough opening above the door 102 to . . . 2a push the mail into the box 200 beyond the inward most end of the door top 102a (as in FIG. 4) where it will drop to be deposited in the box, then . . . 2b withdraw hand, such that the hand and arm maintain downward force on the door 102 by sliding on top of it, until . . . 3 hand is fully removed, which n::moves downward force and allows spring 108 to push the pivot 104 back to the closed position at top of the tracks 106. Simultaneously the door will pivot back to close the opening wherein the bottom part 102b is vertical and/or resting against the bottom edge of the box 200.

(12) The dosing pivot action is caused by gravity pulling down on the door bottom 102b which is larger and heavier than the top part 102a. An optional spring 112 may be added in any fashion that will aid the closing pivot action. For example, FIGS. 2A-3 show a leaf spring with a cantilever attachment to the door 102 and a sliding contact against the track 106.

(13) Referring also to FIG. 5, the door top 102a may be angled, curved, or otherwise offset inward to make it easier to push in above the pivot pin 104 enough to begin pushing downward without needing to push inward very far. The slanted profile shown in most drawings is only an example of any shape that will accomplish this objective. For example, another shape that accomplishes this is an outward projecting handle, also shown in FIG. 5.

(14) Also shown in FIG. 5, the door top 102a profile may be curved/curled inward, optionally in addition to a different offset profile, and preferably with the most curled or rounded portion at the top edge in order to enable sliding the hand/arm without catching or scraping on the top edge, especially as the hand is withdrawn.

(15) The door top 102a height HDa is less than the door bottom 102b height HDb, preferably much less. It should be minimized to maximize the length of the mail/package that will fit in the box, see FIG. 4.

(16) As shown in FIG. 3, the self-closing door 100 may be a separate device that could be an add on for attaching to the front of any mailbox 200, e.g., replacing an original door 202. It is shown as an attachment in FIGS. 1A, 1B, 2A and 2B. This attachable version may have a band 110 surrounding the mailbox opening and holding everything together with the tracks 106 suitably positioned. Otherwise, as shown in FIGS. 1C and 2C, the tracks 106 may be built into/on/at the front edge of the mailbox opening.

(17) Many variations of the basic design are contemplated, some being exemplified in the drawings e.g., FIG. 5 door examples, and all being within the scope of the invention provided they accomplish the inventive method of use described herein that incorporates a door panel on a sliding pivot. Certain embodiments of the present invention could include, but are not limited to: an inverted version where the “top” door part 102a, i.e., the shorter part that is pushed inward is below the pivot 104 and the track 106 extends upward without a spring 108. Gravity will provide the bias force for self-closing by sliding downward. Gravity could also provide the self-closing pivoting force if the shorter door part 102a is weighted to be heavier than the longer part 102b. the sliding pivot 104 could be braced by a vertical extension that would prevent left-right tilting of the pivot and door, note that this is accomplished by item 112. embodiments if the sliding bottom part 102b is constrained by the tracks 106. the springs 108 and/or tracks 106 could be moved, shaped differently, and/or replaced by a single e.g., central spring with or without a track. different types of springs 108 and 112 tracks 106 could extend down below the mailbox 200 bottom so that the pivot 104 could be pushed all the way down to the bottom, thereby allowing a largest package height. other embodiment variations will probably become evident to a designer utilizing the teachings of this disclosure.

(18) The present application, both written and drawn represent potentially different embodiments at different stages of the invention's development to date, all of which should be considered within the scope of this disclosure and any inventions described herein. The drawings may contain annotations including, for example notes, text labels, and the like. Annotations on the drawing pages should be treated as part of the written description, and have equal weight thereto. Another embodiment allows the door to pivot outward as it nears the bottom of the frame, increasing the internal space of the mailbox. Embodiments of the inventions may be made of wood, plastic, metal or other materials.
