DETAILED DESCRIPTION OF THE EMBODIMENTS

[0053] In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular embodiments, procedures, techniques, etc. in order to provide a thorough understanding of the present technology. However, it will be apparent to one skilled in the art that the present technology may be practiced in other embodiments that depart from these specific details.

[0054] Referring now to the drawings, and particularly to FIGS. 1-14, an embodiment of the doorjamb safety system and method of the present technology is shown and generally designated by the reference numeral 10.

[0055] In FIG. 1, a new and novel doorjamb safety system 10 of the present technology for holding open an automatically closing door is illustrated and will be described. More particularly, the doorjamb safety system 10 has a handle unit 12, a wedge unit 40 and a spring loaded triangled chock unit 90. In operation, these units can provide a compact device that can easily be inserted into a doorjamb between a doorframe and a door to secure the door in an open configuration and preventing the door from closing. It particularly, the doorjamb safety system 10 can be utilized to prevent an automatically closing door from closing, where the door includes an automatic closing mechanism such as, but not limited to, spring hinges or a above spring arm attached to the door.

[0056] As best illustrated in FIGS. 1-2, the handle unit 12 is shown slidably engaged over a body portion 42 of the wedge unit 40 which houses a spring (illustrated in FIGS. 11-12), and an elongate shaft 92 of the triangled chock unit 90 attached between a proximal end of handle unit 12 and a chock 104. It should be noted that chock 104 terminates the shaft 92, which is attached to the handle unit 12. The shaft 92 can include a plurality of openings or holes 94 that are for locking purposes when a locking button 68 is depressed into one of them once the unit 10 is engaged in a doorjamb.

[0057] Referring to FIGS. 1-5, the handle unit 12 can include a handle housing 14 featuring a hollow interior 16, where the handle housing 14 can be any configuration graspable by a user. An outer surface of the handle housing 14 can include padding, grips, texturing, etc. to assist in gripping the handle housing 14 by a user’s hand. In some or all embodiments, an interior surface of the handle housing 14 that defines the hollow interior 16 can be tapered in a converging manner towards an end wall 17 that provides a closed end of the hollow interior 16.

[0058] A shaft-receiving member 18 can be concentrically located inside the hollow interior 16 featuring an open end in communication with a shaft-receiving cavity 20 and one or more bores 22 in communication with the shaft-receiving cavity 20. The open end can extend exterior of an open end of the handle housing 14. The cavity 20 can be along a longitudinal axis of the handle unit 12, and the bores 22 can be lateral to the longitudinal axis, with the bores 22 being located exterior of the handle housing 14.

[0059] A second member 24 can be concentrically located in the hollow interior 16 and can include a second cavity 28. The shaft-receiving member 18 can extend from an end of the second member 24. The second member 24 can have a width or diameter larger than the shaft-receiving member 18, thereby creating an angle, chamfered or curved transition section 26. Accordingly, an area of the hollow interior 16 adjacent the second member 24 can be less than an area adjacent the shaft-receiving member 18.

[0060] An end cap 30 can be attached to the handle housing 14 by threading or by fasteners 32 to close off an end of the handle housing 14 and/or the second cavity 28. An electronic device 36 can be included with the end cap 30 to provide additional safety or alerting functions. A battery can be associated with the electronic device 36 or can be received in the second cavity 28. The electronic device 36 can be any one or any combination of, but not limited to, a light, an audible device, a siren, a strobe light, a tethering line, a speaker, a microphone, a radio receiver, a two-way communication device, a transmitter, a transceiver, a location tracking device or any other similar device(s). It can be appreciated that the electronic device 36 can be a modular unit 34 attachable and interchangeable with the end cap 30. A flanges or stop edge of the end cap 30 can abut against a flange or lip of the modular unit 34, and where tightening of the end cap 30 against the end of the handle housing 14 could secure the electronic device 36 in place and/or in electrical contact with contacts utilized with a battery received in the second cavity 28.

[0061] It can be appreciated that the handle unit 12 can be accomplished without a separate end cap 30 and/or the electronic device 36. Further, the second cavity 28 can be utilized to store peripheral items such as, but not limited to, a tether line, a flashlight, medical supplies, a water container, etc.

[0062] It can further be appreciated that the handle unit 12 can include an infrared (IR) alarm motion detecting system (not shown). The IR alarm motion detecting system can be part of or utilized with the electronic device 36, and can activate an alarm, alert and/or indication when movement is detected. Further, a signal can be transmitted from the handle unit 12 to a remote device or system when movement is detected. This signal can further include location information for that particular handle unit 12 detecting movement. Further, the IR motion detecting system can activate an explosive device located in or associated with the handle unit 12. Further and/or in combination with any of the above, the handle unit 12 can include a laser activated explosive device (not shown), which could activate an explosive device located in or associated with the handle unit 12 when a body or object breaks the beam. These explosive device embodiments can be utilized for military or tactical purposes.

[0063] Referring to FIGS. 1, 2 and 6-8, the wedge unit 40 can include a body portion 42 slidably receivable in the hollow interior 16 of the handle housing 14. The body portion 42 can have a shape corresponding to the handle housing 14 and a width or diameter less than the handle housing 14. A hollow interior 44 is defined in the body portion 42 that is in communication with a first open end of the body portion 42. A shaft-receiving section 46 extends from a wedge end 70 into the hollow interior 44, with a shaft-receiving bore 48 being defined through the shaft-receiving section 46 along a longitudinal axis of the wedge unit 40.

[0064] The shaft-receiving bore 48 is configured to slidably received therethrough the shaft 92 of the triangled chock unit 90. A first longitudinal channel 50 and a second longitudinal channel 52 are defined in the shaft-receiving section 46, and which are both in communication with the shaft-receiving bore 48. A longitudinal ridge 54 extends into the shaft-receiving bore 48 to separate and define the first and second longitudinal channels 50, 52. The ridge 54 terminates prior to an end of the shaft-receiving bore 48 to define a transition opening 56 communicating between ends of the first and second longitudinal channels 50, 52. It can be appreciated that the first and second longitudinal channels 50, 52 and the transition opening 56 can act and/or be configured as a keyway.

[0065] A button housing 60 can extend out from a side of the body portion 42 for utilization with the button 68. A first bore 62 can be defined through the button housing 60 configured to slidably receive a first portion of the button 68, and a second bore 66 can be defined through the shaft-receiving section 46 configured to slidably receive a second portion of the button 68. Consequently, reciprocal movement of the button 68 while assembled in the button housing 60 provides a distal end of the second portion of the button 68 to be moved in the shaft-receiving bore 48 a predetermined distance. It can be appreciated that the button housing 60 can defined a button cavity 64 that can house a spring 69 configured to pull the button 68 toward the button housing 60 toward a default locked position or push the button 68 to a default unlocked position. The user could pull the button 68 away from the button housing 60 to retract it. Alternatively, the button 68 can have an extended cam under it that is held in the up position by way of a small pressure spring and locking pin. The first bore 62 can have a width or diameter larger than the second bore 66, accordingly the first portion of the button 68 can have a width or diameter larger than the second portion. The first bore 62 can be aligned with the second bore 66, and can be lateral to the longitudinal axis of the body portion 42.

[0066] The wedge end 70 can be provided at a second open end of the body portion 42 opposite to that of the first open end defining the hollow interior 44. The wedge end 70 can include a flat and/or planar end wall 72, and a pair of wedge sides 74 located on sides of the planar end wall opposite each other. The end wall 72 can extend lateral across an end of the body portion 42 opposite to that of the open end. The shaft-receiving bore 48 is defined through the planar end wall 72 to slidably receive at least a portion of the shaft 92.

[0067] Each of the wedge sides 74 can include a flat surface 76 provided at an angle/inclination in a direction toward each other. The wedge sides 74 can accordingly extend above or beyond a lateral width of the end wall 72 and/or above or beyond a longitudinal distance away from the end wall 72. The configuration of the wedge sides 74 can consequently create a notch defined by the end wall 72 and sidewalls of the wedge sides 74 that are perpendicular to the end wall 72.

[0068] A pad 80 can be attached to the flat surface 76 of each of the wedge sides 74. The pad 80 can be configured in a shape corresponding with the flat surface 76, and include edges that transition with edges or sides of the flat surface 76 and/or wedge sides 74 to create a smooth transition therebetween. The pad 80 can be made of a material softer than the wedge sides 74 to enhance a grip or friction force against a surface of the doorframe and/or door when in use. The material of the pad 80 can be, but not limited to, plastic, rubber, silicon, foam and the like, and can further include texturing or patterns to increase grip. Attachment of the pad 80 to the flat surface 76 can be accomplished by, but not limited to, adhesives, mechanical fasteners, mechanical interlocking components, magnets, hook and loop fasteners, tongue and groove, ratchets, tabs and the like.

[0069] Referring to FIGS. 1, 2, 9 and 10, the triangled chock unit 90 can include the shaft 92 and the chock 104. The shaft 92 can include a first end section 96 and a second end section 102. The first and second end sections 96, 102 can have a width or diameter less than the shaft 92, and can each include one or more bores 100 defined therethrough and lateral to a longitudinal axis of the shaft 92. It can be appreciated that the first and second end sections 96, 102 can be of the same width, diameter and/or shape, or can be different.

[0070] The shaft 92 can include a plurality of openings 94 defined therein or therethrough that are lateral to the longitudinal axis of the shaft 92. The openings 94 are each configured to receive the second portion of the button 68.

[0071] A detent 98 laterally extends from a side of the shaft 92 opposite to that of the openings 94, as best illustrated in FIG. 10. The detent 98 is configured to be slidably received in and travel along the first and second longitudinal channels 50, 52 and/or the transition opening 56.

[0072] The first end section 96 or the second end section 102 can be configured to be received in the cavity 20.

[0073] The chock 104 can include a flat end side 106, a pair of tapering sides 108, and a connection end 110. The tapering sides 108 are angled in a converging manner from the end side 106 to the connection end 110, and can each include textures, patterns, grips, configurations to enhance contact with a variety of different doors, doorframes and/or building structures.

[0074] An extension 112 can extend from the connection end 110 and a cavity 114 can be defined through the extension 112 and into at least portion of the chock 104. The cavity 114 can be configured to receive the first end section 96 or the second end section 102 so that one or more bores 116 defined through chock 104 are alignable with the bores 100 of the first end section 96 or the second end section 102 assembled therewith. The bores 116 can be defined laterally to and in communication with the cavity 114. Mechanical fasteners 122 can be inserted in the bores 116, 100 and utilized to secure the chock 104 with the shaft 92. The fasteners 122 can be, but not limited to, rivets, screws, bolts, pins and the like. It can be appreciated that the chock 104 can be threadably attached to the first end section 96 or the second end section 102 by way of threading associated with the cavity 114 and the first end section 96 or the second end section 102, respectively.

[0075] Recesses, notches and/or through holes can be defined in the chock 104 to reduce its weight.

[0076] FIGS. 11 and 12 best illustrates the handle unit 12, the wedge unit 40 and the triangled chock unit 90 assembled to form the doorjamb safety system 10. The first end section 96 or the second end section 102 of the shaft 92 can be inserted into the cavity 20 so that the bores 22 of the shaft-receiving member 18 and the bores 100 of the first or second end section 96, 102, respectively, are aligned. Fasteners, rivets or pins can then be utilizing with the bores 22, 100 to secure the shaft 92 to the handle housing 14 together.

[0077] A biasing element or spring 120 can be inserted into the hollow interior 16 of the handle housing 14 so that an end thereof contacts the end wall 17.

[0078] After which, the open end of the body portion 42 of the wedge unit 40 can be inserted into the hollow interior 16 of the handle housing 14 so that the shaft 92 is received through the shaft-receiving bore 48 and the spring 120 is located in the hollow interior 44 of the body portion 42 between the body portion and the shaft-receiving section 46. It can be appreciated that the button 68 should be in a retracted position so that the second portion of the button 68 does not contact or prevent travel of the shaft 92 through the shaft-receiving bore 48. It can be further appreciated that the shaft 92 should be orientated so that the detent 98 is received in either of the first or second channels 50, 52.

[0079] In this assembled configuration, movement of the handle unit 12 and the wedge unit 40 toward each other would compress the spring 120 and provide a biasing force thereagainst. Additionally, this movement would further bring the open end of the body portion 42 toward the end wall 17 and consequently contacting the converging interior side of the handle housing 14. It can be appreciated that further movement of the wedge unit 40 toward the handle unit 12 increases the frictional holding force of the tapered interior side of the handle housing 14 against the exterior side of the body portion 42. This friction force can be utilized to hold the handle unit 12 and the wedge unit 40 in a compressed configuration.

[0080] With the wedge unit 40 assembled with the handle unit 12, then the chock 104 can be assembled with the free end section 96, 102 of the shaft 92. This can be accomplished by placing the cavity 114 of the chock 104 to receive either the free end section 96, 102 of the shaft 92 so that the bores 116 of the chock 104 and the bores 100 of the free end section 96, 102 of the shaft 92 are aligned. Then fasteners or rivets 122 can be utilized to secure the two parts together.

[0081] In this assembled configuration, the tapered sides 108 of the chock 104 and the pad 80 or angle flat surfaces 76 face each other in a spaced apart relationship. The assembled doorjamb safety system 10 can then be inserted into an open doorjamb so that one of these spaced apart relationships is configured to receive a corner of a doorframe 2 and the other spaced apart relationship is configured to receive a corner of a door 4, as best illustrated in FIG. 12.

[0082] The handle unit 12 can then be pushed towards the wedge unit 40 so that the pads 80 contact their respective door frame 2 and door 4 surfaces, thereby squeezing two adjacent surfaces forming the corner of the door frame 2 between one of the tapered sides 108 and one of the pads 80, and squeezing two adjacent surfaces forming the corner of the door 4 between the other of the tapered sides 108 and the other of the pads 8.

[0083] When a suitable squeezing force is applied, the button 68 can be pressed so that the second end of the button 68 is received in one of the holes 94 of the shaft 92, thereby locking the doorjamb safety system 10 in an operation configuration that prevents the door 4 from pivoting to a closed position.

[0084] The first and second channels 50, 52 can be configured to provide the triangled chock unit 90 in two or more different rotational orientations. For example, a first rotational orientation can provide the chock 104 rotated 90 degrees with respect to the wedge sides 74 for insertion of the chock 104 through the doorjamb. In the exemplary, this first rotational orientation can include the detent 98 of the shaft 92 received in the first channel 50. The doorjamb safety system 10 can then be rotated so the tapered sides 108 are flush and in contact with their respective doorframe 2 and door 4 surfaces. After which, the wedge unit 40 can moved so that the detent 98 travels along the first channel 50 until it is capable of entering the transition opening 56. Then the wedge unit 40 can be rotated so that the detent 98 travels across the transition opening 56 where the detent 98 can then enter the second channel 52. This rotation of the wedge unit 40 places the doorjamb safety system 10 in a second rotational orientation with the pads 80 flush and in contact with their respective doorframe 2 and door 4 surfaces.

[0085] In response to pushing the handle unit 12 in the direction of the chock 104, spring 120 is compressed, which causes the shaft 92 terminating in the chock 104 to extend out from wedge end 70. As the handle unit 12 is rotated, the chock 104 rotates to a transverse position in relation to wedge end 70.

[0086] In the retracted position, the chock 104 driven by the handle unit 12 cannot rotate in relation to wedge end 70. The detent 98 on the shaft 92 is aligned with the first or second channel 50, 52, which allows full travel of the handle unit 12 over the body portion 42 of the wedge unit 40 compressing the spring 120. Upon extension, the detent 98 slides in the first channel 50, while the transition opening 86allows rotation of the handle unit 12 and its attached shaft 92 with chock 104. Rotation of the handle unit 12, and thus the shaft 92, moves the detent 98 out of the way. Upon release of the handle unit 12, the detent 98 engages to set the wedge unit 40 in a locked position, which prevents re-extension of the chock 104 and locks out rotation. In this way, the wedge unit 40 is made secure so that any tension applied to the wedge unit 40 from a pulling force on the handle unit 12 does not compress the spring 120, nor allow rotation of the chock 104, maintaining a secure connection.

[0087] The handle unit 12, the wedge unit 40 and/or the triangled chock unit 90 can be made of any fire resistant material or thermally insulating material.

[0088] In an exemplary use and as best illustrated in FIGS. 13-14, it can now be understood that the doorjamb safety system 10 can be utilized to hold a door 4 open, even if the door 4 includes an automatic self-closing mechanism. Further, the angle of the flat surfaces 76 and the tapered sides 108 would result in an angle at which the door 4 is held open. With the door 4 opened to a 90 degree position, from waist height the user can push the doorjamb safety system 10 as far as it will go forward into the doorjamb area gap were the hinges are attached, the wedge end 70 of the wedge unit 40 will fill the gap making contact on both the door frame 2 and the edge of the door 4 on each side of the wedge end 70.

[0089] The triangled chock unit 90 in its normal position can slide through the gap to the backside of the doorframe 2 and door 4 by pushing the spring-loaded handle unit 12 forward into the doorframe gap. This pushing motion will extend the chock 104 out past the backside of the doorframe 2 and door 5. Then the user can turn the handle unit 12 90 degrees to the right, which will rotate the chock 104 90 degrees behind the door frame 2 and door 4 so the chock 104 is now in its locking position with the tapered sides 108 being perpendicular to the floor and the edges of the triangled wedge between the door frame 2 and the door 4 locking the unit 10 in place.

[0090] The door 4 may tend to close a minor amount due to the spring in the handle unit 12 giving to the pressure of the closing mechanism of the door 4 against the doorjamb safety system 10. One way to stop this from happening, the user could hold the door 4 in its full 90 degree or more open position, then press the lock button 68, and then wiggle the door 4 open a bit until the button 68 depresses into one of the holes 94 in the shaft 92. Then the user can hold the button 68 down and release the door 4, the door tension from trying to close will put tension on the button 68 and keep it from popping up and releasing the door 4.

[0091] With the doorjamb safety system 10 locked in the doorjamb, the door 4 is held in the open position until the user releases the button 68, rotates the chock 104 for removal out of the doorjamb. While in place, the user can activate the light 36 on the rear of the handle unit 12. This can be accomplished by rotating the end cap 30 until contacts are made between the end cap 30 and the handle housing 14 or by pressing/tapping a button on the end cap 30. For example, the user can tap once to illuminate a red light, twice for yellow or three times for a green blinking light. The different colored lights can be used to signal a danger threat for that room prior to entering, which can be utilized with first responders, firefighters or law enforcement officers. Pressing the button a fourth time could turn the light 36 off. In the alternative, if the light 36 stays a solid color without blinking, then this could signal that the battery has energy for a remaining predestined time, for example, 2 hours of charge/energy remaining.

[0092] It can be appreciated that the battery can be rechargeable utilizing a recharging port associated with the handle housing 14, the end cap 30 or the light 36. The light 36 can include printed circuit board or a controller unit configured or configurable to control operations of the light 36.

[0093] To remove the doorjamb safety system 10 from the doorjamb, the user can slightly push the door 4 open, thereby removing the pressure the button 68 wherein and it will release itself from the shaft hole 94 by the button spring that will pop it up out of the hole 94. After which, the user can reverse the above installation steps of it from the doorjamb. This can be accomplished by rotating the doorjamb safety system 10 so that the chock 104 is in line with the opened doorjamb. Then the user can simply pull the doorjamb safety system 10 away from the doorjamb, thereby retracting the rotated chock 104 out through the opened doorjamb.

[0094] While embodiments of the doorjamb safety system and method have been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the present technology. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the present technology, 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 the present technology. For example, any suitable sturdy material may be used instead of the above-described. And although holding open an automatically closing door have been described, it should be appreciated that the doorjamb safety system and method herein described can also be suitable for clamping or anchoring a handled unit to a building structure, board, paneling or wall.

[0095] Therefore, the foregoing is considered as illustrative only of the principles of the present technology. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the present technology 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 present technology.
