DETAILED DESCRIPTION

(10) The explanations and illustrations presented herein are intended to acquaint others skilled in the art with the teachings its principles, and its practical application. Those skilled in the art may adapt and apply the teachings in its numerous forms, as may be best suited to the requirements of a particular use. Accordingly, the specific embodiments of the present teachings as set forth are not intended as being exhaustive or limiting of the teachings. The scope of the teachings should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference into this written description.

(11) This disclosure claims priority to U.S. Provisional Patent Application No. 62/059,312 filed on Oct. 3, 2014, the contents of which is hereby incorporated by reference herein in its entirety for all purposes.

(12) The present invention provides an improved storm door that overcomes the disadvantages present in prior art swinging storm doors. The improved storm door of this invention can be used without requiring a swing space. The improved storm door can be easily opened even by a person carrying groceries or who is physically handicapped. Furthermore, the improved storm door remains parallel to a wall of the dwelling, such that wind is less likely to catch and thrust open the storm door. The present invention can be installed as a retrofit item in an existing door opening with minimum modification.

(13) Referring to FIG. 1, an easy glide storm door assembly according to one exemplary embodiment of the invention is generally shown at 20 installed in front of a standard exterior entry door 22. The door assembly 20 comprises a door 24. One exemplary of the door 24 is shown having glass panels which are replaceable with screen panels. The shape and arrangement of the door 24 could, however, be of any suitable type and may or not may not correspond to the shape of the exterior door 22. The door 22 is suspending from above by a roller track system, generally indicated at 26. The door 24 is thus configured to slide to one side following in the roller track system 26 so that the user does not need to step back in order to open the door 24. The door 24 can therefore slide easily to one side, and stay in the open condition without further restraint, thus permitting easy and total access to the exterior door 22.

(14) FIG. 2 is a cross-sectional view taken from lines 2-2 in FIG. 1 which shows how the door 24 is installed in front of (i.e., on the exterior side of) the exterior door 22. The track system 26 is firmly attached to a door head 28 or exterior wall structure via a wall bracket 30. The wall bracket 30 could be any appropriate shape to attach the track system 26 to the door head 28. For example, an L-shaped bracket can be used to attach the track system 26 to a vertical wall, or a Z-shaped bracket to a horizontal ceiling. The door 24 is hung from a thrust bolt 32 in the track system 26 via a door bracket 34. FIG. 3 illustrates an exploded view of attachment of the door 24 and the roller track system 26 via the door bracket 34. Typically at least two door brackets 34 are firmly disposed on a top surface of the door 24. The door bracket 34 takes the form of a generally Z-shaped plate having a higher portion and a lower portion. The lower portion of bracket 34 is firmly fixed through holes on the top surface of the door 24 by screwing, welding or other suitable means. The upper portion of bracket 34 includes a notch 36. The notch 36 is configured to hook over the head of the thrust bolt 32, and a nut 40 is generally designed to fasten the door bracket 34 and the thrust holt 32 as shown in FIGS. 2 and 3.

(15) Returning to again FIG. 2, a fixed bolt 42 is permanently attached to the track system 26. The height of the door 24 can be adjusted by turning the thrust bolt 32 so that the door 24 can keep appropriate gap between the bottom surface of the door 24 and a sill 44. A counter bolt 46 is located over the fixed bolt 42. When the counter bolt 46 is tightened to the fixed bolt 42, the counter bolt 46 can prevent the thrust bolt 32 from loosening and firmly maintain the height of the door 24.

(16) FIGS. 2-7 illustrate how the track system 26 is composed to permit sliding movement of the door 24. The track system 26 generally comprises a pair of rollers 38 and a track 48. The roller 38 generally includes two pair of wheels 50, which can freely rotate on the both sides of the roller 38. The track 48 takes the form of a generally a U-shaped strut channel as shown in FIGS. 6 and 7. The rollers 38 are configured to slide inside the track 48. In both ends of channel of the track 48, a stopper 52 is disposed to prevent the roller 38 from escaping the track 48. One example of the stopper 52 could be a screw across the track 48. However, any means of preventing the roller 38 from escaping could be the stopper 52. (E.g. an end block or cap.)

(17) Returning to FIGS. 1 and 2, a flexible top guard 54 is firmly attached to the exterior face of the door 24 adjacent its top edge. The top guard 54 extends above the door 24 and partially overlays the tack 48 to keep bugs out of the gap between the track system 26 and the door 24. Also, the top guard 54 prevents rain and dust from entering and can protect the track system 26 and the exterior door 22. The top guard is designed to closely ride against the track 48. FIGS. 1 and 2 depict a right side guard 56, which is firmly disposed along the right side edge of the door 24 to seal the gap between the door 24 and a wall. A left side guard (not illustrated) can be attached to the door 24 to accomplish a similar purpose.

(18) The door assembly 20 may further include a lower guide 62 to help maintain the door 24 in a vertical orientation at all times, even when being slid open and dosed. FIGS. 1, 2 and 9 show the guide 62, which is firmly fixed in the sill 44. In particular, the guide 62 includes a generally U-shape slot that confines a bottom portion of the door 24. Furthermore, the guide 62 can prevent the door 24 from shaking by gusts of wind.

(19) The present invention also can conveniently replace with an existing prior art storm door because the door 24 can be configured to slide right or left corresponding to a pre-installed exterior door. In FIG. 1, the door 24 is configured to slide right, but, the door 24 can be configured to slide toward the left. Thus, the present invention can be easily adapted to both left and right knob door applications

(20) Many modifications and variations of the present invention are possible in light of the above teachings and may be practiced otherwise than as specifically described while within the scope of the contemplated invention.

(21) Any numerical values recited herein include all values from the lower value to the upper value in increments of one unit provided that there is a separation of at least 2 units between any lower value and any higher value. As an example, if it is stated that the amount of a component or a value of a process variable such as, for example, temperature, pressure, time and the like is, for example, from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, it is intended that values such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 etc. are expressly enumerated in this specification. Far values which are less than one, one unit is considered to be 0.0001, 0.001, 0,01 or 0.1 as appropriate. These are only examples of what is specifically intended and all possible combinations of numerical values between the lowest value and the highest value enumerated are to be considered to be expressly stated in this application in a similar manner. As can be seen, the teaching of amounts expressed as parts by weight herein also contemplates the same ranges expressed in terms of percent by weight. Thus, an expression in the Detailed Description of the Teachings of a range in terms of at x parts by weight of the resulting polymeric blend composition also contemplates a teaching of ranges of same recited amount of x in percent by weight of the resulting polymeric blend composition.

(22) Unless otherwise stated, all ranges include both endpoints and all numbers between the endpoints. The use of about or approximately in connection with a range applies to both ends of the range. Thus, about 20 to 30 is intended to cover about 20 to about 30, inclusive of at least the specified endpoints.

(23) The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. The term consisting essentially of to describe a combination shall include the elements, ingredients, components or steps identified, and such other elements ingredients, components or steps that do not materially affect the basic and novel characteristics of the combination. The use of the terms comprising or including to describe combinations of elements, ingredients, components or steps herein also contemplates embodiments that consist essentially of the elements, ingredients, components or steps.

(24) Plural elements, ingredients, components or steps can be provided by a single integrated element, ingredient, component or step. Alternatively, a single integrated element, ingredient, component or step might be divided into separate plural elements, ingredients, components or steps. The disclosure of a or one to describe an element, ingredient, component or step is not intended to foreclose additional elements, ingredients, components or steps.

(25) It is understood that the above description is intended to be illustrative and not restrictive. Many embodiments as well as many applications besides the examples provided will be apparent to those of skill in the art upon reading the above description. The scope of the teachings should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes The omission in the following claims of any aspect of subject matter that is disclosed herein is not a disclaimer of such subject matter, nor should it be regarded that the inventors did not consider such subject matter to be part of the disclosed inventive subject matter.
