TECHNICAL FIELD
The present invention relates generally to a door urging apparatus. More particularly, it relates to an apparatus for urging a hatch door to a substantially fully open positional state and suspending the hatch door in the open position and further to help urge the hatch door into closed positional state.
FIELD AND BACKGROUND
Vehicles of all types typically have storage compartments or areas that are accessible either from the interior of the vehicle or the exterior of the vehicle, normally the access to these storage compartment areas is from the exterior of the vehicle which is accommodated through a door or alternatively termed a hatch, wherein this hatch on a land-based vehicle is typically mounted in a vertical wall and on a marine vehicle a horizontal wall, typically termed a deck. In either case the hatch typically has a locking latch to lock it in the closed operational state and also has some form of retainer to secure the hatch door in the open operational state as with the vehicle having movement it is preferred that the hatch be secured in either the closed operational state or the open operational state. For securing the hatch door and the open operational state a clasp is typically used to secure the door on an adjacent area on the vertical or horizontal surface adjacent to the hatch as in the case of the land or marine vehicle respectively.
Specifically in the case of a land-based vehicle, wherein as previously stated the hatch doors mounted on a vertical wall the clasp that holds the hatch door in the open operational state is holding the hatch door open as against the forces of gravity such that a failure of the clasp could result in injury to a person who is utilizing the access of hatch into and out of the storage compartment, such that a failure of the clasp would result in the hatch door falling and coming in contact with the person possibly causing injury, this as opposed to the marine vehicle application wherein on a horizontal surface the hatch door would typically stay open in place against a horizontal surface even if the clasp failed. So for the land vehicle vertical mounting configuration for the door hatch, the clasp for securing the door into the open operational state becomes even more important for the previously mentioned safety issues and further for the process of opening the door hatch, i.e. in going from the closed operational state to the open operational state wherein the process of manually moving the door hatch could also result in harm the person opening door hatch if it were to slip out of their hand while lifting as it could cause physical harm as the force of gravity is always acting upon the door hatch causing it to fall during the opening process, this as opposed to for example to a conventional building entrance door that opens laterally being hinged vertically that is not affected by gravity. Wherein, if the conventional building entrance door were let go of during the process of going from the closed to the opened state or from the open state to the closed state, the door would not fall from the force of gravity on to the person using it. Thus the vertically mounted door hatch that typically hinges upon the upper surface is more critical in the area of the particular apparatus that urges the door from the closed state to the open state and then returning to the closed state, while at the same time suspending the hatch door securely in the open state.
The prior art in this area in so far as hatch doors is primarily associated with the marine arts, in other words the hatch doors are typically mounted horizontally wherein the effects of gravity in going from the closed state the open state are not as much of a consideration outside of some need for retaining the door in the open state due to the inherent movement of the marine vehicle or vessel. Further, a lot of the priority in the marine area on the hatch door apparatus is to accommodate moving the hatch door from the closed state to the open state and back to the closed state, are concerned with the ability of opening the door for a full 180° to maximize hatch opening access, which can require special hinges on the hatch door and also on the urging apparatus for helping the door open under its own power need to have extra hinged joints where expansions and decoupling are needed to allow the hatch door to open the 180°.
Looking specifically at the typical prior art in the above mentioned areas and in particular starting with the marine hatch door arts, in U.S. Pat. No. 4,811,680 to Genth, disclosed is a deck hatch assembly for marine craft that is formed in the upper deck surface of the marine craft on the port and starboard sides. In Genth, a submerged surface is integrally formed in the upper deck surface, being provided with a hatch opening surrounded by a raised peripheral ridge. The raised ridge in Genth, together with the submerged surface and the upper deck surface, forms a drain channel for directing water away from the stern of the marine craft. A pivotably mounted hatch cover in Genth is provided for normally sealing and closing off the hatch opening. The hatch cover in Genth may be raised upwardly from the bulkhead of the marine craft toward the stern for the purpose of providing ventilation to below deck compartments and for allowing access to the upper deck surface from below deck areas. A pair of gas spring assemblies in Genth is provided for positively and automatically retaining the hatch cover in the closed, or any one of a number of open positions. The hatch cover in Genth, in the closed position, is completely flush with the upper deck surface and is adapted to conform to the configuration of any deck, including styling lines thereof. Note that in particular in Genth in FIG. 2, that the gas spring assemblies 54 have simple pivotal attachments to the frame side walls 20 and the door 42, thereby restricting the door movement in the fully open position to about what is shown in FIG. 1, being less than ninety degrees, thus restricting the utility of Genth. Note that Genth does not urge the hatch door also into a closed operational state.
Continuing, in the marine hatch door arts in looking at U.S. Pat. No. 3,976,024 to Fillery disclosed is a hatch assembly for a boat that has a hatch cover and a hatch mounting frame to which the cover is hinged by releasable hinges, there being two espagnolette bolts serving the dual functions of hinging and latching the hatch cover to the mounting frame. Retraction of either espagnolette bolt at will from an associated hinge receiver on the mounting frame enables the hatch cover to be swung open left or right handedly, and retraction of both bolts from their receivers enabling the hatch cover to be lifted clear of the mounting frame. Thus, Fillery recognizes the problem identified in Genth or the restricted hatch door opening movement, being limited to about ninety degrees at the most, as Fillery has the espagnolette bolts that essentially allow the hatch door to be removed from its frame, while the stay members 18 are detachable all therefore allowing the hatch door to lay flat on the horizontal surface, see FIG. 4.
Continuing, in a much similar invention, in U.S. Pat. No. 6,105,529 to Kyle disclosed is a hatch assembly that has a function very much like Fillery, in that in Kyle being also for a marine vessel includes an outer frame and a hatch cover hingedly attached to the outer frame on one side thereof. The Kyle assembly also includes an elongated hatch adjuster comprising a telescoping rod assembly which includes an outer tube, a tubular extension and a flexible coupling which connects the tubular extension and outer tube in axial alignment when in a first position, see FIG. 3A in particular. The rod in Kyle is slidably received within the outer tube and tubular extension and maintains the assembly in axial alignment as the hatch cover is rotated from a closed position to an angle of at least about 135 degrees, being far more that Genth's opening limitation of being less that ninety degrees. As the hatch cover in Kyle approaches 180 degrees, the rod is withdrawn out of the outer tube which permits the flexible coupling to bend so that the hatch cover can be rotated a full 180 degrees, thus the has a moveable joint at 18, see FIG. 3B, that allows the telescoping rod assembly (being designed for securing the door at any position between fully open and fully closed) bend an additional amount via spring 18 as shown in FIG. 3A, plus an additional telescoping of rod 16 to completely facilitate the full 180 degree door opening, as shown in FIGS. 3A and 3B. The hatch assembly in Kyle also includes a clamp for fixing the rod 20 and outer tube 14 in a fixed position to thereby maintain the cover in a preselected position with respect to the frame. Although Kyle does accomplish the function of allowing the door to fully open to the 180 degrees, it has a high degree of mechanical complexity in requiring a higher number of parts in the assembly.
Moving away from the marine hatch door arts and into the general hatch door arts for a vehicle roof for an escape hatch in U.S. Pat. No. 6,572,182 to Lamparter, et al. disclosed is a motorized vent and escape hatch assembly has a mounting ring fastened to a vehicle roof around a hatch hole, and a hatch cover that is attached to the mounting ring by a first over center hinge linkage mechanism pivotally connecting one side of the hatch cover to the mounting ring and a second over center mechanism pivotally connecting an opposite side of the hatch cover to the mounting ring. Each over center hinge linkage mechanism in Lamparter, et al., has first and second lever members pivotally connected to the mounting ring at one end, first and second plungers that are connected to the respective first and second plungers at the opposite end and that extend into opposite ends of a tube that is connected to the hatch cover. A compression spring in Lamparter, et al., located in the tube, biases the first and second plungers away from each other. Each over center hinge linkage mechanism in Lamparter, et al. is associated with a drive mechanism that pivots the first and second lever members toward or away from each other to raise or lower its side of the hatch cover with respect to the mounting ring. Each drive mechanism in Lamparter, et al. includes first and second gear housings attached to the mounting ring, first and second gear sets disposed inside the respective gear housings, first and second electric motors attached to the respective gear housings for driving the first and second gear sets, and first and second output shafts that are driven by the first and second gear sets and that extend out of the first and second gear housings respectively with the first and second lever members being keyed to the first and second output shafts respectively. The gear sets in Lamparter, et al. are compound gear trains that reduce speed and increase torque.
Next, moving to the land based vehicle arts for a hatch door that opens primarily at an upward angle looking in at U.S. Pat. No. 5,667,268 to Bump disclosed is a protective door system and its complementary box-type structurally-secure service compartment mounted on a firm base, which comprises a slanted roof as a modification of the service compartment on a door side wherein the angle of slant is between about 30 and 60 degrees below horizontal and represents no more than one-third of the total roof area. Further, in Bump a structurally-secure door opening as a modification of the service compartment on a door side, wherein the opening extends from within two feet of the horizontal roof to a location along the vertical wall of the service compartment, and a structurally-secure protective door fitting into the door opening is matched with a weather-type seal, fastened with hinges overhead at its junction with the roof, and secured with a latch at its junction with the vertical wall, wherein the door was made with the same dimensions and slant angle as the slanted roof and vertical side openings. Finally, Bump has a pivoting brace attached in a structurally-secure manner between the protective door and said service compartment to allow multiple open door positions, and the brace pivots at its service compartment attachment. Here in Bump the maximum raised position of the upper slanted portion of said protective door allowance is no more than about 60 degrees above the horizontal, see column 2, lines 43-65 and FIG. 4, or for a total door opening angle of about ninety degrees that the member 33 allows for, being much the same as Genth for not having any special member 33 mountings other than is assumed as a conventional pivotal mounting attachment for the lifter member 33, as there is no teaching evident in Bump relating to unique pivotal attachments of lifter member 33 pivotal mounting.
The prior art has simply not solved the problems encountered while moving the hatch door in a vertically mounted position from the closed to the open operating states to facilitate an assisted door opening function with a door urging apparatus that provides for nearly 180 degrees of opening while suspending the door safely in the open positional operating state, being suspended vertically upward. Furthermore, when the door is closed from the open positional state to the closed positional state, the closing movement should be dampened to counter balance the weight of the door, thus resulting in the door being pushed downward to close until the door is nearly closed, wherein the door urging apparatus then reverses itself to pull the door shut, making the door security latching an easy process, as opposed to the door urging apparatus fighting the ability of the user to close and latch the door securely shut, which would require the user to continuously apply force to hold the door in the fully closed position to effectuate the latching to secure or lock the door in the closed operating position state.

In looking at FIGS. 1 through 10, the door urging apparatus 50, in the form of a kit 50, see FIG. 10 especially, is for use with an existing door 85 hingedly 70 mounted 80 in a frame 60, the door 85 moving 95 via the hinged 70 mount 90 about a hinge axis 75 relative to the frame 60, as previously supplied or mounted in the recreational vehicle 310 vertical wall 315, see FIGS. 8 and 9, with the door 85 moving from the closed operational state 105, to the crossover operational state 115, and an open operational state 120, looking at particular to FIGS. 5, 6, and 7. The door urging apparatus 50 includes the offset bracket 130 that has a base 130 forming a plane 140, with the base 135 having a centrally positioned base axis 145 that is perpendicular 165 to the plane 140, see FIGS. 5, 6, and 7, also with an arcuate planar element 185 having a proximal end portion 190 and a distal end portion 195. Wherein the proximal end portion 190 extends substantially perpendicularly 165 therefrom the base 135 and the distal end portion 195 terminating in a first pivotal attachment 200, see FIGS. 1, 4, 5, 6, 7, and 10. The first pivotal attachment 200 having a first pivotal axis 205, wherein the first pivotal axis 205 is parallel to the plane 140 and perpendicular to the base 135 axis 145, forming a first distance 220 from the plane 140 to the first pivotal axis 205 and a second distance 225 from the base 135 axis 145 to the first pivotal axis 205, see again FIGS. 5, 6, and 7. Wherein, relationally the first distance 220 is in the range of about zero point five (0.5) to one point five (1.5) times the second distance 225, wherein the base 135 is affixed 150 to the door 85 such that the first pivotal axis 205 and the hinge 70 axis 75 are parallel and adjacent to one another, see again FIGS. 5, 6, and 7.
Further included in the door urging apparatus 50, in the form of a kit 50 is the plate 230 including the second pivotal attachment 210 projecting therefrom, the second pivotal attachment 210 has a second pivotal axis 215 that is positioned parallel to the first pivotal axis 205, see FIG. 4. Wherein the plate 230 is affixed to a frame 60 portion opposite of the hinged 70 mount 80, wherein the connective axis 240 is formed from the first pivotal axis 205 to the second pivotal axis 215, wherein the connective axis 240 is parallel to each of the first 205 and second 215 pivotal axes, see FIGS. 5, 6, and 7. Further, a relational axis 245 is formed from the second pivotal axis 215 to the hinge 70 axis 75, wherein the relational axis 245 is perpendicular to each of the second pivotal axis 215 and the hinge 70 axis 75, see FIGS. 4 through 7. Note that the plate 230 could also be attached to other that the frame 60, i.e. being attached to another part of the structure of the recreational vehicle 310.
Additionally included in the door urging apparatus 50, is the gas spring assembly 275 having a lengthwise cylinder 280 with a rod 285 telescoping therefrom, wherein the gas spring assembly 275 provides a dampened force 290 extending said rod outward, see FIGS. 4 through 7. The gas spring assembly 275 is pivotally attached 295 and 300 respectively as between the first pivotal attachment 200 and the second pivotal attachment 210, again see FIGS. 4 through 7. Wherein, operationally the door 85 is in the cross over operational state 115 when the connective axis 240 and the relational axis 245 are in alignment 250 to one another, see FIG. 6, wherein the door 85 is urged 110 into the closed operational state 105 in going from the cross over operational state 115 to the closed operational state 105 and further the door 85 is urged 125 into the open operational state 120 in going from the cross over operational state 115 to the open operational state 120. The first 220 and second 225 distance are also sized to have the connective axis 240 intersect the base 135 and the base axis 145 intersection when the door 85 is in the open state 120 resulting in no moment 270 loading translating from the base 135 to the door 85 when the door 85 is secured in the open operational state 120, see FIG. 7, resulting in a lower loading placed upon the door 85, wherein the door 85 is typically constructed from a rigid foam core sandwiched by plastic/fiberglass laminates, thus the loading ultimately from the gas spring assembly 275 to hold the door 85 open 120 is diffused to the point of not rupturing the door 85 materials, wherein the actual door 85 loading is in shear over a wide area 175 of the reinforcement element 170 acting through the adhesive 180 to help preclude door 85 rupture, cracking, or piercing, from the from the gas spring assembly 275 force 290 to hold the door 85 open 120.
Alternatively, the door apparatus 50 can further include the reinforcing element 170 affixed between the base 135 and the door 85, wherein the reinforcing element 170 is at least three (3) times the area 155 of the base 135, wherein operationally the reinforcing element 170 reduces a per unit loading of the base 135 to the door 85 by a factor of at least three (3) stemming from the dampened force 290, see in particular FIGS. 1, 4, through 7, and 10, so as described above for the reduction of door 85 loading from the gas spring assembly 275 force 290 to hold the door 85 open 120.
