Definitions

  • Overhead garage doors are sometimes equipped with a seal or weatherstrip which is attached to the bottom surface of the door and is designed to contact the driveway or garage floor to prevent or minimize water intrusion and wind infiltration.
  • seals are normally designed to rest directly on the concrete, asphalt, or other driveway surface and, in general, present either an inverted U-shape or a rounded or oblong cross-sectional configuration. Both typical shapes are normally compressed by the weight of the door to effect sealing with the underlying pavement.
  • Weatherstripping of this type must endure wide temperature swings of the underlying pavement as well as shock loads imposed by the garage doors upon their closing. Temperatures may vary greatly in a single day as well as from season to season. In northern climates, problems are often experienced with the weatherstripping freezing to the concrete slab and then tearing as the door is opened. Shock loads may also vary greatly depending on factors such as overall door weight and the method of closing the door, i.e. automatic closing or manual closing.
  • weatherstripping such as that described above normally has a limited life span.
  • infiltration from moisture, wind, insects and even rodents becomes a problem which normally can only be remedied successfully by replacement as repair is generally not a viable option.
  • replacement is generally difficult or awkward due to the position of the weatherstripping, i.e. on the bottom of the door, as well as from frozen or rusted fasteners which hinder removal of the damaged product.
  • deterioration of the seal is significant, replacement may be further hindered by deterioration or rotting of the door itself, which may require repair or partial replacement of the lower edge of the door before a new seal can be installed.
  • Another object of the present invention is to provide a threshold assembly which resists deterioration from temperature extremes, ultraviolet rays, and ozone gas, and which maintains flexibility despite harsh conditions.
  • a further object of the present invention is to provide a threshold for the weatherstripping which is highly resistant to shock loads from driving over the threshold and which, in combination with the weatherstripping provides a cooperative sealing assembly, the threshold assembly being durable for providing a long service life.
  • a threshold assembly for garage doors having a threshold plate means with a bottom surface designed for sealing to the underlying pavement and an upper surface designed for cooperatively accepting the conventional weatherstripping applied to the bottom of the garage door, thereby sealing the bottom of the door.
  • the upper surface of the threshold is also designed to minimize shock loads from vehicles driven thereover in either direction, having surface portions sloping away from the approximate center in both directions.
  • the weatherstripping attached to the bottom of the garage door may have, in general, a tubular or inverted U-shape which the present invention receives on the outer sloping surface.
  • the present invention may be composed of a number of suitable materials, such as, for example, a thermoplastic elastomer, a preferred material being a PVC vinyl product which is flexible and resistant to UV and ozone degradation and chemical substances such as oil and gasoline which might come into contact with the threshold.
  • suitable materials such as, for example, a thermoplastic elastomer, a preferred material being a PVC vinyl product which is flexible and resistant to UV and ozone degradation and chemical substances such as oil and gasoline which might come into contact with the threshold.
  • the invention is also relatively inexpensive to produce and install, with no specialized tools or experience required.
  • numeral 10 designates generally a typical garage door, shown in closed position in garage 12.
  • the door shown is of the sectional type, with individual panels 14 pivotally mounted so as to follow a curved track when raising or lowering the door.
  • This is not meant to limit the invention in any way, as the present assembly may also be used with unitary garage doors which swing outwardly from their base mounting when the door is raised and in residential or commercial use.
  • the invention involves the cooperative functioning of a base plate means or threshold 16 and a conventional weatherstrip means 18.
  • the weatherstrip may have, in general, an inverted U-shaped or tubular configuration and is secured to the lowermost or bottom edge 20 of the garage door with a suitable securing means, such as rivets 22 or screws.
  • the rivets or the like are inserted through the weatherstrip and into the door at suitable selected intervals usually along the approximate center of the main body portion 24 of the weatherstrip.
  • the threshold itself is normally approximately 3 1/4" wide from front to back to minimize the profile presented to the sun and other degradative forces as most of the width located outside the plane of the garage door is covered by the weatherstrip.
  • the leg portions of the weatherstrip include a front leg 26 and a rear leg 28, the front leg being disposed on the side of the weatherstrip which extends outwardly from the interior of the garage.
  • the front leg illustrated here is longer than the rear leg, as shown in Figure 2, however, the present threshold also accepts weatherstripping having legs of equal lengths or tubular forms as discussed hereinbelow.
  • Threshold member 16 has in general, an inverted V-shaped configuration with a generally flat bottom side or base 30.
  • the base is provided with a plurality of inverted V-shaped grooves 32, which are designed to receive and hold a suitable securing means such as adhesive material 34 for securing the threshold to the slab 36.
  • the grooves are concentrated in the central portion of the threshold, thereby helping to maintain needed flexibility in the front and rear portions adjacent the central portion.
  • the combination of adhesive in the normally porous concrete or asphalt slab and in the centralized grooves provides a very effective holding assembly without sacrificing the flexibility of the sloping portions which bear the brunt of the load from the vehicles driving thereover.
  • the front portion or side of the base which extends radially outwardly from the interior of the garage, has a sloping upper surface 38 with a relatively low pitch.
  • This upper surface 38 graduates to a steeply pitched wall portion 40, which serves as a dam for rain water and the like and also as a guide for the weatherstrip as it descends.
  • the rear leg 28 is guided into the approximate 45° angle where wall 40 and sloped surface 38 intersect and the front leg 26 is caused to flex into a slightly concave configuration to aid in water runoff.
  • Continuous with wall portion 40 is generally flattened suface 42 at the apex of the inverted V-shaped threshold 16.
  • Extending radially from surface 42 toward the interior of the garage is the rear portion or ramp 44 which serves as a transition from the garage floor to the sloping upper surface 38.
  • the pitch is increased from that of surface portion 38 to provide the requisite height for the damming effect of wall 40 and also to act as a wedge to drive the threshold against the slab downwardly as opposed to laterally or radially, under the pressure of vehicle tires passing thereover.
  • the threshold 16 may be produced from a number of suitable materials, a preferred composition being a thermoplastic elastomer.
  • the elastomer which is more specifically a flexible PVC vinyl, may be, for example, a product sold under the trademark GEON 8804 by B.F. Goodrich Co., or products manufactured by Tenneco and sold under the numerical designations #2025 or #1280.
  • These products and other similar vinyl products, polyurethanes, or copolyesters and even some natural or synthetic rubbers are chosen for resistance to ultraviolet and ozone degradation and resistance to attack from oil, gasoline, and other common chemicals which might be picked up by tires on the road or in a garage.
  • Other qualities include flexibility and stability at both low temperatures of -30°F to -40°F and high temperatures ranging from 140°F to 250°F.
  • Ultraviolet degradation is minimized normally by the addition of carbon black in quantities of approximately 2% to 2.5% by weight. Further stability against UV degradation and brittleness at cold temperatures is provided by the addition of a clay filler to the basic compounds.
  • the PVC material has a shore durometer rating ranging from approximately 70A to 90A and an ASTM D 746 Brittle point of approximately -30°F. Tensile strength may range from approximately 1700 to 3000 psi.
  • the adhesive used to secure the threshold to the base slab may be any of a number of suitable types compatible with the material used for the threshold, for example, a structural adhesive. The adhesive is chosen for properties of stability at temperature extremes, volatility, allowing its application in temperature extremes, and the ability to fill and grip the normally porous concrete or asphalt surface while bonding the threshold to the slab.
  • a further advantage is the support provided for the garage door by the present threshold which helps to prevent or minimize sagging or bowing of the garage door, especially where the door has significant weight and/or length. Such conditions lead to early failure of the door from the stress imparted thereto.
  • support is provided by the threshold along the entire length of the door in both lateral and radial directions.
  • the threshold has a low profile to minimize the friction of vehicle tires passing thereover, thereby minimizing the possibility of the threshold moving after installation, and also to facilitate flushing out or sweeping out the garage floor.
  • the profile is sufficiently raised, however, to provide a significant damming effect against moisture, rain or snow, dust and other forces.
  • Further protection against UV degradation is provided by the shielding effect of the weatherstrip 18 which covers most of the exposed surface 38 of the threshold when the garage door is closed.
  • the weatherstrip is protected from temperature extremes due to the insulative qualities of the threshold and adhesive which prevent contact between the weatherstrip and the slab.
  • a significant advance is weatherproofing is provided by the present invention, with an inherently stable product that is easy to apply and which provides a long service life.
