DETAILED DESCRIPTION
The inventive Christmas tree stand with a float system, a low water indicator, and an independent spring compression system 23, and a method of using the same, will now be discussed with reference to FIGS. 1 through 8B. Although the scope of the present invention is much broader than any particular embodiment, a detailed description of the preferred embodiment follows together with drawings. These drawings are for illustration purposes only and are not drawn to scale. Like numbers represent like features and components in the drawings. For the ease of understanding not all features of the invention are shown in each drawing.
With the inventive design through self-adjusting spring system placement of the tree is quick and easy. The tree is pushed into the tree stand and the tree will stay where placed, and with this invention there is no more need of getting on the floor to screw the tree into the stand. Any adjustments that are needed are simply accomplished by positioning the tree straight and letting go, and not by adjusting the screws. For most applications the inventive tree stand spring compression stabilization system will hold between about a 21⁄2 inch to about a 5 inch diameter tree trunk (average size) and up to about 8 feet tall tree. The low water indicator system activates a buzzer to inform the user or owner that water is needed for the tree in the stand, and which will assist in a longer life for the tree. This inventive design improves on the existing products by informing the user or owner exactly when the tree needs to be watered, and again there is no longer a need for any screw adjustment system. With this invention there is no more guessing on how much water to add, no overfill, and the tree placed within the inventive tree stand will never go dry.
The invention further comprises of a Christmas tree stand with a float system, and a low water indicator means. The inventive stand, depending on the size, can hold up to, for example, about 3 quarts of water, or with about 2 quarts of water with the tree or plant inside the inventive stand or planter. At least one low water indicator, or a buzzer, or an alarm, or a light, will automatically get activated when the water is low, such as, for example, when about 1 quart of water is needed, or when for example, the water reservoir is down to say 1 quart of water. With this invention the Christmas or plant tree stand will not run dry. This invention greatly improve the functionality of a Christmas tree stand by having a low water indicator, thus preventing the dryness of a Christmas tree, which can also be a cause or source of fire, especially, when a Christmas tree is adorned with Christmas lights.
In operation typically a Christmas tree is preferably placed in the center of the planter or stand, and is then pushed down into the planter or the tree stand. The tree should be stabilized using the automatic adjustment means of the spring compression stabilization system. To adjust the lean (if needed) one would move or rotate the tree or the plant to where it is preferably straight or erect, and the tree or the plant will be secured to stay where placed. This inventive Christmas tree stand can hold trees or plants up to about 8 feet high, and from about 21⁄2 inch to about 5 inches in diameter (average size). It should be understood that for a larger diameter tree one would need an enlarged or bigger version of this inventive apparatus, and similarly for a smaller diameter tree one would need a smaller version of this inventive apparatus.
Now referring to FIG. 1, through FIG. 8B, which illustrate various views of the inventive Christmas tree stand with a float system, a low water indicator, and an independent spring compression system 23, where a Christmas tree 1, is held upright inside a stand 2, which further comprises a water reservoir 6, having a water level 26. The Christmas tree 1, is supported by an inventive spring compression stabilization system 18, which serves to position the Christmas tree 1, securely and upright into the water reservoir 6, inside of the stand 2, which also contains an inventive low water indication float device system 3, which is preferably encased in a cylinder or a tube 12. The spring compression stabilization system 18, is designed to substantially match a typical Christmas tree trunk 31, so as to cause it to be aligned with the axis of the tree trunk 31. The spring compression expansion system 18, allows for an opening 38, that can expand to accommodate various diameter Christmas tree trunks 31, while maintaining grip and stability through multiple points of contacts 21, 22, with the Christmas tree trunk 31. This expansion of the grip can be accomplished in a number of ways, such as, for example, providing a plurality of spring steel pieces 21, 22, that can expand to accommodate the diameter and a trunk portion 31, of the Christmas tree 1. The formed spring steel pieces 21, 22, are preferably securely attached to a metallic ring 19. The metallic ring 19, is mounted to the inside of the stand 2, via at least one securing means 30, such as, using screws 30, through the mounting screw holes 20. The low water float indicator system 3, which is encased in the tube 12, is attached to the stand 2, which contains a plunger 8, that rises and falls with the water level 26, through a float 7, that is attached to the plunger 8. The low water float indicator system 3, is activated when the water level 26, is low, for example, when the water level 26, is down to say one quart of water 50, remaining in the water reservoir 6. The plunger 8, having the float 7, will automatically get lowered when the water level 26, is low, thus pushing an activation wire 10, onto an electrical connection 9, such as, for example, a metal washer 9, which would then trigger a power source wire 11, which is connected to a power source 16, such as, a battery pack 16, thus completing the circuit, and setting off the buzzer or alarm 17, which is mounted to the stand 2.
FIG. 1, illustrates a side perspective view of an inventive Christmas Tree with stand apparatus 23, according to one embodiment of this invention. As shown in FIG. 1, the Christmas tree 1, having a trunk 31, and branches 32, is held upright in a tank assembly stand 2, and where the Christmas tree 1, is supported by the inventive spring compression stabilization system 18, and where the inventive floatation device system 3, provides the water 50, monitoring for the Christmas tree 1. The tank assembly stand 2, has a stand base 42, and a stand neck or mouth 46, having an opening 45. The water reservoir 6, has a water level 26, and where the water level 26, is continuously, and automatically monitored by the inventive floatation device system 3, for the replenishment of the water 50. Preferably, the stand 2, has an overfill or catch channel 5.
FIG. 2, illustrates a side perspective view of an inventive stand 2, with an inventive floatation device system 3, according to an embodiment of this invention. FIG. 2, is also a close up view of the floatation device system 3, mounted into the stand 2, showing holes or openings for wiring access 4, along with the overfill or catch channel 5, and the plunger system 8. The plunger system 8, comprises of a plunger rod or shaft 27, with an activation disc or tab 28, at the upper end, and a float 7, at the opposite or lower end. The float 7, is preferably allowed to freely move along the plunger shaft 27, between the upper float stop 14A, and the lower float stop 14B, as more clearly seen in FIG. 4. Within the stand 2, one could have a battery pack 16, an alarm or buzzer 17, and an ON/OFF switch 24. It should be appreciated that the over fill channel 5, is to catch any water 50, that may overflow when the water 50, is poured inside the stand 2, via the water reservoir mouth or opening 36, into the water reservoir 6, and the tube 12.
FIG. 3, illustrates a detailed enlarged view of an inventive stand 2, with an inventive floatation device system 3, according to another embodiment of this invention. FIG. 3, shows the inside view of the water reservoir 6, which is located inside the stand 2. The float 7, raises and lowers the plunger 8, due to the fluctuation of the water level 26, inside the water reservoir 6. The electrically conductive component 9, such as, an electrically conductive metal washer 9, is used to activate the alarm or buzzer 17, as more clearly seen in FIG. 6. This is done due to the fact that as the water 50, in the water reservoir 6, either evaporates or is consumed by the Christmas tree 1, the water level 26, gets lower, and this also lowers the float 7, to go low, which then drags the plunger system 8, to go low, and then at a predictable or set point the activation disc or tab 28, pushes the activation wire 10, to come in contact with the electrically conductive component 9, which has a connection with a power source wire 11, thus completing the circuit between the activation wire 10, and the power source wire 11, and which then activates the buzzer or alarm 17, to be activated. However, once the water 50, is poured or replenished into the water reservoir 6, the float 7, rises along with the water level 26, and the activation disc or tab 28, is then also separated from the activation wire 10, and the electrically conductive component 9, as the activation disc or tab 28, also rises with the water level 26, thus deactivating the circuit, and also the alarm or buzzer 17. Optionally, one could also have an ON/OFF switch 24, to either activate or deactivate the alarm or buzzer 17.
FIG. 4, illustrates an enlarged view of the inventive floatation device system 3, according to one embodiment of this invention. FIG. 4, shows an enlarged view of the floatation device system 3, with the float 7, at the bottom of the floatation device system 3, held on the plunger rod or shaft 27, of the plunger system 8, by two float stops 14A, 14B, such as, an upper float stop 14A, and a lower float stop 14B. For some applications the float stops 14A, and 14B, could be rubber washers 14A, 14B. The electrically conductive metal washer 9, and the power source wire 11, would complete the electrical connection with the activation wire 10, as discussed elsewhere. Preferably, the cylinder or tube 12, encases the floatation device system 3. The side of the tube 12, is cut along 13B, to allow water 50, access into the tube 12, to raise or lower the float 7, which is mounted to the inside of the stand 2. The electrical activation component 9, has an opening 29, for the passage of the plunger rod or shaft 27. For some applications one could also have at least one plunger stabilizing component 15, having an opening 25, for the passage of the plunger rod or shaft 27. For some applications the plunger stabilizing component 15, could be at least one hard rubber washer 15, that could be used to stabilize the plunger 8, as it move vertically along the tube 12. It should be appreciated that the plunger stabilizing component 15, could be along at any location of the tube 12, as long as it did not interfere with the functioning of any of the components of the plunger system 8, such as, for example, the shaft 27, the float 7, etc.
FIG. 5A, illustrates a side perspective view of an inventive tube 12, containing an inventive floatation device system 3, prior to being secured to an inventive water reservoir 6, of the Christmas Tree 1, with stand 2, apparatus, according to one embodiment of this invention. Figure SA, also shows the tube 12, having a slit or cut out 13B, which also contains the floatation device system 3, as being unattached or separate from the water reservoir 6. Similarly, the water reservoir 6, has a cut out or slit 13A, as will be more clear in FIG. 5B.
FIG. 5B, illustrates a side perspective view of an inventive tube 12, containing an inventive floatation device system 3, after being secured to an inventive water reservoir 6, of the Christmas Tree 1, with stand 2, apparatus, according to one embodiment of this invention. As shown in FIG. 5B, the edges of the slit or cutout 13A, of the water reservoir 6, is joined or mated with the edges of the slit or cutout 13B, of the tube 12, and secured thereto, using at least one securing means 33, such as, a water proof epoxy 33, a plastic epoxy 33, to form a water 50, access opening 13, between the tube 12, and the water reservoir 6. The tube 12, containing the floatation device system 3, is now securely mounted and mated with the water reservoir 6, and allows for water 50, access between the water reservoir 6, and the tube 12, via slit or opening 13.
FIG. 6A, illustrates a side perspective view showing an inside view of the inventive stand 2, showing an opening 36, 45, for water 50, access to the inventive floatation device 3, for the Christmas Tree 1, with inventive stand 2, apparatus 23, according to one embodiment of this invention. FIG. 6A, shows a float device plunger 8, that has been elevated by water through cut-out 13, within the stand 2. In this embodiment the wiring 10, 11, is on the upper or top surface of the stand 2, around the stand mouth 46, such that the activation wire or tab 10, and the power source wire or tab 11, are electrically activated when the electrically conductive metallic activation disc or tab 28, moves down and makes an electrical connection between the activation wire or tab 10, and the power source wire or tab 11, to activate the alarm or buzzer 17. For some applications, the electrical activation disc or tab 28, could also be the electrical contact 9, as more clearly shown in FIG. 6A, that creates the electrical circuit or connection between the activation wire or tab 10, and the power source wire or tab 11, to activate the alarm 17.
FIG. 6B, illustrates a side perspective close up view of the wiring 10, 11, and the inventive floatation device system 3, that is set into the stand 2, for the Christmas Tree 1, with inventive stand 2, apparatus 23, according to one embodiment of this invention. FIG. 6B, is a close-up view of plunger 8, mounted into the stand 2, with access hole or opening 4, for the wiring 10, 11, where one of the activation wire 10, or the power source wire 11, is attached to the electrically conductive metallic washer 9. Thus, when the plunger 8, moves down due to the evaporation or consumption of water 50, by the Christmas tree 1, the activation disc or tab 28, pushes the non-connected wire 10, 11, to come in contact with the electrically conductive disc or washer 9, and thus complete the electrical circuit to activate the alarm or buzzer 17.
FIG. 7, illustrates a side perspective view of the inventive floatation device system 3, along with a wiring diagram for the activation of a low water 51, condition for the Christmas Tree 1, with inventive stand 2, apparatus 23, according to one embodiment of this invention. FIG. 7, further shows the tube 12, which contains the floatation device system 3, mounted inside the stand 2, and connected to the water reservoir 6. Also, shown is the battery pack 16, which could contain a power source 16, such as, for example, double A batteries 16, triple A batteries 16, 9 volt batteries 16, an AC/DC power source 16, to name a few, which is triggered when the activation disc 28, of the plunger system 8, makes contact with the activation wire 10, which in turn contacts the electrically conductive metallic washer 9, to the power source wire 11, which completes the circuit and activates the alarm or buzzer 17.
FIG. 8A, illustrates a perspective view of an inventive tree stand spring compression stabilization system 18, according to one embodiment of this invention. FIG. 8A, shows the tree stand spring compression stabilization system 18, which comprises of a metal band 19, having an opening 38, and having a plurality of spring steel components 21, 22, secured to the inside peripheral wall of the metal band 19, such as, via one securing means 41, such as, a weld 41. For some applications the metal band 19, could be attached or secured to the stand 2, via securing means 30, such as, screws 30, using, for example, mounting holes 20. For some application the Christmas tree trunk 31, is secured and held in place via spring steel 21, 22, such as, for example, four 5′′long, 3⁄4′′ wide spring steel 22, and four 4′′ long, 3⁄4′′ wide spring steel 21.
FIG. 8B, illustrates a perspective view of an inventive tree stand spring compression stabilization system 18, showing a tree trunk 31, that is pushed through the spring steel components 21, 22, through the opening 38, and is placed in an erect and stabilized mode, according to one embodiment of this invention. It should be understood that the securing means 30, are used to secure the metal band 19, to the inner peripheral wall of the stand 2. The securing means 30, can be used to secure the outside wall of the stand 2, to the inside wall of the metal band 19, or the inside wall of the metal band 19, can be secured to the inside wall of the stand 2. However, for some applications the metal band 19, could be a part of the neck of the stand 2, as the integration of the metal band 19, into the stand 2, would be caused by the integrated securing means 30, such as, a weld 30, a channel 30, etc., as shown in FIG. 1.
It should be appreciated that water 50, when replenished reaches a water level 26, which could be the first water level threshold 51, and then as the water 50, is consumed by the tree 1, or evaporates, the water level 26, then reaches a second water level threshold 52. Thus, the first water level threshold 51, is when the alarm 17, automatically deactivates, as the float 7, rises with the water level 26, and moves the electrical activation disc or tab 28, away from the electrical contacts 9, 10, and 11. Similarly, when the second water level threshold 52, is reached, the alarm 17, automatically gets activated to indicate that the water 50, needs to be replenished for the inventive apparatus 23, as the electrical activation disc or tab 28, creates the electrical connection between the electrical contact 9, activation wire or tab 10, and the power source wire or tab 11, due to the lowering of the float 7, within the water 50.
The low water 51, indicator can be a buzzer 17, an alarm 17, a light 17, an LED type of light 17, or any other indicating means 17, that will visually 17, or by sound 17, provide an indication to a user that water level 26, is either low or is needed in the tree/plant stand 2.
It should be appreciated that liquid level floats 7, also known as float balls 7, are typically spherical, cylindrical, oblong or similarly shaped objects, made from either rigid or flexible material, that are buoyant in water 50, and other liquids 50. These are non-electrical hardware 7, and frequently used as visual level measurement. Here the float 7, has been incorporated into a switch mechanisms in a fluid tube 12, as a component in monitoring liquid level. It is well known that liquid level floats, or float switches, use the principle of material buoyancy (differential densities) to follow fluid levels, thus the float 7, would move up or down with the up or down movement of the liquid level 26. Solid floats 7, are often made of plastics with a density less than water 50, or other application liquid 50, and so they float. Hollow floats 7, filled with air are much less dense than water 50, or other liquids 50, and are appropriate for some applications.
