Areas that are prone to heavy snowfall can experience difficulties in receiving mail due to inaccessibility to the mailbox created by the snow. Since it is typically the homeowner's responsibility, failure to make a clear path to the mailbox for the mail carrier can result in non-delivery of mail. Making matters worse, snow plows hired to clear the streets can crash into and destroy an owner's mailbox. Areas which are prone to heavy snowfall can deal with these issues on a semi-regular basis during the winter season.
An extendable and resilient mailbox is implemented in which the mailbox can revertibly extend outward on a telescoping rod to improve accessibility to the mailbox during heavy snowfall. The extendable mailbox is also configured with break-away action which enables the mailbox to laterally move and resiliently revert (or “break away”) to a base position. For example, when a snow plow inadvertently crashes into the extended mailbox, the mailbox will laterally move in the direction of the encounter to reduce the chances of or prevent the mailbox's destruction. Once the snow plow has passed or at least is no longer clashing with the mailbox, the extendable mailbox reverts back to its base position.
In typical implementations, the extendable mailbox may include a set of telescoping rods to which a mail receptacle is secured to enable the receptacle to move outward and inward relative a post. The post may be a wooden 4×4 which is secured to a base, such as the ground. The post includes a bracket to which an enclosure element is secured, and the telescoping rods may be connected to the enclosure element. Inside the enclosure element is spring which enables break-away action when the receptacle is extended. That is, the receptacle and telescoping rods can laterally pivot when some outside force inadvertently crashes into them, and then revert back to their original position once the outside force disappears.
The end telescoping rod which is furthest from the post includes a handle to enable a person to pull and thereby extend the telescoping rods and receptacle. Furthermore, a retractable rod can also be implemented which enables a user to retract the telescoping rods and receptacle back to their un-extended base position. The retractable rod may be a rigid rod which can also be used to extend the mailbox when the user cannot access the handle in front.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure. These and various other features will be apparent from a reading of the following Detailed Description and a review of the associated drawings.
Like reference numerals indicate like elements in the drawings. Elements are not drawn to scale unless otherwise indicated.
The inner telescoping rod 215 is positioned inside of and extends from the middle telescoping rod 210. The middle telescoping rod 210 is positioned inside of and extends from the outer telescoping rod 205. Rear ends of the middle and inner telescoping rods may have flanges which engage with corresponding flanges on front ends of the outer and middle telescoping rods, respectively. Other telescoping designs to connect telescoping rods together are also possible, such as system in which corresponding threads are utilized to screw ends of telescoping rods together.
The extendable mailbox 105 includes a retractable rod 220 which is used to retract the extended mailbox and provide upper support for the mailbox. Additionally, the retractable rod can be used to push out the mailbox from the post-side in scenarios in which the front of the mailbox is obstructed with snow. In this regard, the retractable rod may be more rigid than flexible (e.g., string) so that it can adequately push out the mailbox. In some implementations, the retractable rod may be telescoping with a clutch or other rotational lock mechanism to lock the mailbox in place when pushed outward. The locking mechanism may be provide a clockwise twist to lock and counter-clockwise twist to unlock the retractable rod.
The top of the bracket 130 includes a slit 310 inside which the retractable rod 220 rests. The slit enables the rod to pivot when the mailbox is impacted by some outside force (e.g., a plow). In this implementation, the retractable rod is positioned at an upper portion of the mailbox, but in other implementations, the retractable rod may be positioned on a lower portion of the mailbox.
The broken lines show the various components underneath the receptacle 110 which would typically be blocked from the vantage point in
The extendable mailbox 105 includes a sealed enclosure 320 which, as discussed in greater detail below, encases the pivot point for the mailbox to laterally pivot when impacted by some outside force, like a plow, car, etc. The sealed encasing is fully encased on all sides to prevent rain, snow, etc., from entering and causing rust on its components.
The bolts 520 which connect the telescoping- and post-side U-shaped boxes 505 and 510 together create the pivot point 515 about which the extendable mailbox 105 laterally pivots left and right responsive to some impact from a plow, car, bicyclist, etc. A spring 405 is attached to opposing sides of the telescoping- and post-side U-shaped boxes which creates a sprung hinge that causes the break-away action. Specifically, the extended mailbox springs back to a position of alignment with the post 125 after some impact causes it to pivot. The spring may be attached to the opposing U-shaped boxes using some bolt or, in some implementations, the spring can be welded to the enclosure's sides (not shown).
Various exemplary embodiments are now disclosed. In one embodiment, an extendable mailbox is disclosed which comprises: a post which is secured to a base; a mounting bracket secured to the post; a enclosure attached to the bracket, wherein the enclosure includes a spring; a set of telescoping rods connected to the enclosure, and which extends outward from the enclosure; a receptacle bracket attached to one or more telescoping rods of the set of telescoping rods; and a receptacle secured to the receptacle bracket, wherein extension of the set of telescoping rods moves the receptacle outward from the post.
In an example, the post is vertically oriented from the base. In another example, the mounting bracket is secured to an upper portion of the post. In another example, the extendable mailbox further comprises a handle positioned on an end of the set of telescoping rods to enable a user to pull the receptacle outward. Another example further comprises a reflective material positioned on one or more of the receptacle rods in the set to provide greater visibility of the extendable mailbox. In another example, the enclosure is sealed to make its components waterproof. Another example further comprises a retractable rod to enable retraction of the receptacle and the set of telescoping rods. As another example, the retractable rod is connected to the mounting bracket, and wherein the mounting bracket includes a slit through which the retractable rod is positioned. As another example, the retractable rod is connected to a top portion of the receptacle, in which removable cover attaches to the top portion of the receptacle to cover the retractable rod and screw holes from outside elements. In another example, the enclosure includes two opposing U-shaped boxes connected together at a pivot point, wherein a post-side U-shaped box is attached to the post and a telescoping-side U-shaped box is attached to the set of telescoping rods. In another example, one end of the spring is attached to the post-side U-shaped box and an opposite end of the spring is attached to the telescoping-side U-shaped box. As another example, a bolt connects the two U-shaped boxes together, in which the pivot point is about the bolt. In another example, the telescoping-side U-shaped box has curved portions to enable swiveling inside the enclosure.
