DETAILED DESCRIPTION OF THE INVENTION

With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new restraint device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 6, the door restraint assembly 10 generally comprises a hinge unit 12 that is hingedly coupled between a door 14 and a door frame 16. Each of the door 14 and the door frame 16 may be components of an entry into a building, an entry into a room in a building or other type of man door 14. The hinge unit 12 comprises a first panel 18 that has a first surface 20, a second surface 22 and perimeter edge 24 extending therebetween. The perimeter edge 24 has a first side 26, and the first panel 18 has a plurality of first apertures 28 each extending through the first 20 and second 22 surfaces. The first surface 20 of the first panel 18 is coupled to the door frame 16.

The hinge unit 12 includes a tube 31 that has a first end 32, a second end 33 and an outer wall 34 extending therebetween. The outer wall 34 is coupled to the first side 26 of the perimeter edge 24 of the first panel 18 having the tube 31 being oriented collinear with the first side 26. The outer wall 34 has a slot 36 extending into an interior of the tube 31. The slot 36 has a bounding edge 38 and the bounding edge 38 has a primary end 40 a secondary end 42. Moreover, the slot 36 angles upwardly on the outer wall 34 between the primary end 40 and the secondary end 42.

The hinge unit 12 includes a second panel 44 that has a primary surface 46, a secondary surface 48 and an outer edge 50 extending therebetween. The outer edge 50 has a top side 52, a bottom side 54 and a lateral side 56 extending therebetween. The second panel 44 has a plurality of second apertures 58 each extending through the primary 46 and secondary 48 surfaces, and the primary surface 46 of the second panel 44 is coupled to the door 14. Fasteners, such as screws or the like, are extended through the first and second apertures 58 to fasten the hinge unit 12 to the door 14 and the door frame 16.

The hinge unit 12 includes a cup 60 that has an upper wall 62 and an outer wall 64 extending downwardly therefrom. The outer wall 34 of the cup 60 is coupled to the lateral side 56 of the outer edge 50 of the second panel 44 having the upper wall 62 being aligned with the top side 52 of the outer edge 50 of the second panel 44. Additionally, the upper wall 62 has an air hole 66 extending therethrough. The hinge unit 12 additionally includes a cylinder 68 that has an upper surface 70, a lower surface 72 and an exterior surface 74 extending therebetween. The exterior surface 74 is coupled to the lateral side 56 of the outer edge 50 of the second panel 44 having the lower surface 72 being aligned with the bottom side 54 of the outer edge 50 of the second panel 44. Additionally, the cylinder 68 is positioned between and is aligned with each of the cup 60 and the cylinder 68.

A pin 76 is coupled to and extends upwardly from the upper surface 70 of the cylinder 68. The second end 33 of the tube 31 insertably receives the pin 76 such that the cylinder 68 is rotatably coupled to the tube 31. A first retainer 78, such as a removable pin or the like, extends through the cylinder 68 and engages the pin 76 to inhibit the pin 76 from being removed from the cylinder 68. The pin 76 may have a groove therein or the like that the first retainer 78 engages thereby allowing the first retainer 78 to travel along the pin 76 while inhibiting the pin 76 from being removed from the cylinder 68.

A limiting unit 80 is rotatably positioned in the hinge unit 12. The limiting unit limits rotation of the hinge unit 12 when the door 14 is opened. Moreover, the limiting unit 80 inhibits the door 14 from striking an adjacent wall when the door 14 is opened. In this way the limiting unit 80 protects the wall from being damaged by the door 14 when the door 14 is opened. The limiting unit 80 comprises a spindle 82 that has a first end 84 and a second end 86. The spindle 82 is movably positioned within the tube 31 having the spindle 82 extending out of the first end 32 of the tube 31 and extending into the cup 60. Moreover, the spindle 82 is urgeable upwardly toward the air hole 66 in the cup 60 and downwardly away from the air hole 66 in the cup 60.

A biasing member 87 is positioned within the cup 60 and the biasing member 87 is positioned between the first end 32 of the spindle 82 and the upper wall 62 of the cup 60. The biasing member 87 biases the spindle 82 downwardly from the air hole 66 in the cup 60. A tab 88 is coupled to and extends downwardly from the second end 33 of the spindle 82. The tab 88 has an outwardly facing surface 89, and the outwardly facing surface 89 has a well 90 extending inwardly toward a center of the tab 88. The well 90 has a bounding surface 92 and the bounding surface 92 of the well 90 is threaded.

The limiting unit 80 includes a sleeve 94 that has a first end 96 and a second end 98. The well 90 insertably receives the second end 98 of the sleeve 94 and the sleeve 94 extends outwardly through the slot 36 in the tube 31. Additionally, the first end 96 of the sleeve 94 is exposed with respect to the tube 31. A screw 100 extends into the first end 96 of the sleeve 94 and threadably engages the bounding surface 92 of the well 90 such that the sleeve 94 is removably coupled to the tab 88.

The limiting unit 80 additionally includes a stop 101 that is coupled to the secondary surface 48 of the second panel 44. The stop 101 is aligned with and is oriented collinear with the lateral side 56 of the outer edge 50 of the second panel 44. The stop 101 has a foot 102 extending outwardly therefrom, and the stop 101 frictionally engages the sleeve 94 when the door 14 is opened. The stop 101 urges the sleeve 94 to travel along the slot 36 when the door 14 is opened such that the sleeve 94 travels upwardly in the slot 36 when the door 14 is opened. Additionally, the sleeve 94 urges the spindle 82 upwardly in the cup 60 when the sleeve 94 travels upwardly in the slot 36. Air in the cup 60 passes through the air hole 66 when the spindle 82 is urged upwardly in the cup 60 to depressurize the interior of the cup 60 when the spindle 82 is urged upwardly. The sleeve 94 abuts the secondary end 42 of the bounding edge 38 of the slot 36 when the door 14 is fully opened.

The sleeve 94 slides upwardly along the stop 101 when the door 14 is opened. Moreover, the sleeve 94 abuts the foot 102 on the stop 101 at the same time that the sleeve 94 abuts the secondary end 42 of the bounding edge 38 of the slot 36. In this way motion of the second panel 44 is stopped when the door 14 is fully opened thereby inhibiting the door 14 from striking the wall when the door 14 is opened. The biasing member 87 biases the spindle 82 downwardly in the cylinder 68 when the door 14 is released. Thus, the sleeve 94 travels downwardly in the slot 36 toward the primary end 40 of the bounding edge 38 of the slot 36.

In use, the hinge unit 12 is coupled between the door 14 and the door frame 16 as a replacement of a conventional door 14 hinge. The stop 101 engages the sleeve 94 when the door 14 is opened thereby urging the sleeve 94 to travel upwardly along the slot 36. The sleeve 94 travels along the slot 36 until the sleeve 94 abuts the secondary end 42 of the bounding edge 38 of the slot 36. At the same time, the sleeve 94 abuts the foot 102 on the stop 101 thereby restricting the second panel 44 from travelling any further when the door 14 is opened. In this way the door 14 is restricted from striking the wall, and potentially damaging the wall, when the door 14 is opened. The biasing member 87 biases the spindle 82 downwardly, which in turn urges the sleeve 94 to travel toward the primary end 40 of the bounding edge 38 of the slot 36, when the door 14 is released.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
