## Title
Articulated frame that supports mosquito netting over a bed

## Abstract

This invention provides protection from mosquitoes for an individual lying on a bed. An articulated frame supports mosquito netting over the exposed flesh of the individual. The articulated frame is easily deployed and retracted by the individual while lying on the bed. In the retracted position the bed is fully accessible for making-up or changing the bedding.

## Background
BACKGROUND OF THE INVENTION
Mosquitoes wait at the door to enter a home and then pass through the doorway when the door is opened or they enter through an open window. The mosquitoes then find their way to the bedroom and prey on an individual lying on a bed. This invention provides an easy and inexpensive means of deploying and retracting mosquito netting over the exposed flesh of the sleeping individual lying on the bed. It is assumed that the remaining flesh of the individual not within the protected space is protected by a sheet or blanket. The mosquito netting is held above the individual so that he/she may move in the bed without disturbing the netting or the articulated frame. The mosquito netting can be deployed or retracted by the individual while lying on the bed, and in the process of deployment, transient mosquitoes in the area have a minimal chance of being entrapped in the protected space. In the retracted position, the bed is fully accessible for making-up or changing the bedding.
SUMMARY OF INVENTION
The purpose of this invention is to protect an individual lying on a bed from mosquitoes. An articulated frame is composed of a single horizontal rod supported by two parallel legs attached to the ends of the horizontal rod. The articulated frame straddles the bed, and the bottom of the legs are pivoted below the level of the bed and offset from the head of the bed toward the foot of the bed. The mosquito netting is attached to the horizontal rod and either the headboard of the bed or the wall behind the head of the bed, preferably by clamps. The netting is easily deployed by pulling the mosquito netting toward the foot of the bed and retracted by moving the horizontal rod toward the head of the bed. When deployed, the mosquito netting covers the exposed flesh of the individual sleeping in the bed thereby protecting him/her from mosquitoes. The lower flesh of the individual which is not within the protected space of the mosquito netting is presumed to be protected by a sheet or blanket. When it is necessary to get up in the middle of the night it is very easy to exit and enter the protected space without retracting the horizontal rod, thereby not disturbing a sleeping partner. In the retracted position, the bed is fully accessible for making-up or changing the bedding.
One important and unique feature of this invention is the placement of the pivot point of the articulated frame below the bed and offset from the head of the bed toward the foot of the bed. With this pivot position, the articulated frame is in a stable position when in the retracted position as well as in the deployed position. In the retraced position the articulated frame rests against the headboard or wall behind the head of the bed and will not self-deploy. In the deployed position the articulated frame is restrained by the mosquito netting thereby keeping the mosquito netting taught and preventing it from sagging. Another advantage of this invention is that the mosquito netting can be deployed while lying on the bed and in a manner that minimizes the chance of entrapping a transient mosquito in the protected space. The mosquito netting can also be easily retracted while lying on the bed by reaching up to the horizontal rod and moving it to the retracted position.

DESCRIPTION OF INVENTION
This invention pertains to an articulated frame supporting mosquito netting (hereinafter referred to as netting) over a bed.
FIG. 1 shows a perspective view of the articulated frame and netting (1) deployed over a bed (4). FIG. 2 shows the articulated frame and netting (1) in the retracted position. Referring to FIG. 1, the articulated frame is composed of a single horizontal rod (2) with supported by two parallel legs (3) that are attached to the ends of the horizontal rod (2). The horizontal rod (2) spans the width of the bed (4). The legs (3) rotate in a vertical plane about a pivot mechanism on each side of the bed. The preferred pivot mechanism is illustrated in FIG. 1. It is composed of a board (5), which spans the width of the bed (4), and lag bolts (6) which attach the legs (3) to each end of the board (5). The detail of this pivoting mechanism is illustrated in FIG. 3. The lag bolts (6) serve as axles about which the legs (3) can pivot. An alternative pivoting mechanism is illustrated in FIG. 4. It consists of a bolt (7) passing through the bed frame (8), an anchor nut (9) and a cap nut (10). The pivots (6) are located below the bed (4) and offset (18) toward the foot (19) of the bed from the head of the bed. As shown in FIG. 1 and FIG. 5, the netting (1) is attached to the horizontal rod (2) and the headboard (11) of the bed (4).
Referring to FIG. 1, the netting (1) is attached to the horizontal rod (2) and the headboard (11) of the bed (4). FIG. 5 shows how the netting (1) is attached to the back of the headboard (11) by an anchor rod (12) that passes through a loop in the netting (1). The anchor rod (12) is secured by clamps (13) attached to the headboard (11). FIG. 6 shows Section B-B in FIG. 5 and one of the clamps (13) It also shows the loop in the netting (1) through which the anchor rod (12) passes.
FIG. 7 shows the netting (1) ready to be draped on the articulated frame and the headboard (11). The width of the netting (11) must be greater than the width of the bed (4) so as to ensure that the protected space under the netting is closed at the sides of the bed (4) when the netting (1) is deployed. The netting (1) must be long enough to ensure that, when the articulated frame is deployed, the netting (1) drapes onto the top of the bed (4), thereby completing the closure of the protected space as shown in FIG. 1. FIG. 8 shows Section C-C in FIG. 7 and the loop in the netting (1) through which the anchor rod (12) passes.
FIG. 9 shows Section A-A in FIG. 1 and one of the clamps (14) that secures the netting (1) to the horizontal rod (2). Two or more clamps (14) are adequate for that purpose. FIG. 10 shows Section A-A in FIG. 1 and an alternative to using clamps (14). It shows a loop in the netting through which the horizontal rod (2) passes. In this alternative the loop must provide openings (not shown) to permit the connection of the legs (3) to the horizontal rod (2). Other obvious means of attaching the netting to the horizontal rod (2) and anchor rod (12) may be used, such as decorative ribbon ties, string, or Velcro. Such alternative means are considered to be within the scope of this invention.
FIG. 11 shows the attachment of the netting (1) to a wall (15) behind the head of the bed (4) as an alternative to attachment of the netting (1) to the headboard (11). It is necessary to close the gap between the wall (15) and the bed (4) to prevent mosquitoes from entering the protected space from behind the head of the bed (4). For that reason, a back flap (16) must be included. The back flap (16) can be made of the netting material or any other cloth material. FIG. 12 shows a schematic of the netting (1) laid out flat and shows the back flap (16). Points “a” must be pinned or sewn together as well as Points “b”. While this appears somewhat complex, it is quite easy to accomplish after the netting (1) and back flap (16) are in place and temporarily held together by safety pins or the like. Cutting the back flap (16) to the shape indicated in FIG. 12 can be accomplished after the netting (1) and back flap (16) are in place.
FIG. 13 shows a decorative sleeve (17) covering the horizontal rod (2) and legs (3) of the articulated frame. The material used can have a color and pattern that coordinates with the bedding material or room decor.
The clamps (13 and 14) secure the netting to the horizontal rod (2) and the anchor rod (12) by pinching the netting (1) against the rods (2 and 12). The clamps (13 and 14) shown are usually used to hang brooms and tools on a wall and are readily available in any hardware store. Their design is not part of this invention. Other clamps of different design may be used. One advantage of using clamps (14) to attach the netting to the horizontal rod (2) (see FIG. 9) rather than a loop in the netting (1) (see FIG. 10) is that the deployed position of the horizontal rod (2) can be easily adjusted.
The legs (3), horizontal rod (2), and anchor rod (12) are ideally fabricated with PolyVinyl Chloride (PVC) tubing, although other materials may be used. The legs (3) and the horizontal rod (2) can then be connected using two PVC elbows.
To deploy the netting (1), the individual lying on the bed pulls on the netting (1) at point P (See FIG. 2) toward the foot (19) of the bed thereby pulling the horizontal rod (2) and legs (3) into their deployed position as depicted in FIG. 1. This process limits the chance that a transient mosquito in the area will be entrapped in the protected space To retract the articulated frame, the horizontal rod (2) is simply pushed back to its retracted position as depicted in FIG. 2. Both the deployment and retraction can be done by the individual lying on the bed, e.g., if you hear a mosquito, deploy the netting.
For those who must get up in the middle of the night, it is easy to exit and enter the protected space without retracting the articulated frame. It is easy to duck one's head under the horizontal rod (2) and leg (3) while getting out of bed. Certainly retracting the articulated frame is an alternative, but that may disturb a sleeping partner.
