Definitions

  • the slamming of a door can cause many problems. For instance, there is the risk that the door could be slammed on a person’s fingers - often the fingers of a child. Additionally, slamming a door may result in a person or a pet being locked in a room. Moreover, nobody enjoys the loud sound of a slammed door. Therefore, there is a need for a device that can solve these problems.
  • Certain embodiments of the present technology include a device that discretely controls a door slam and the closure speed of a door as well as provide a lock out so that the door will not close.
  • the device is designed to intelligently react (e.g ., with the ability to respond to varying situations and/or inputs by adjusting its’ state or action) to a slam and/or aggressive door closure, yet does not hinder door closure when the door is closed slowly and more normally.
  • the device is small, easily installed and, through the use of engineered materials (e.g., a smart, shear thickening fluid that reacts to forces applied to it, such as engineered polymeric compositions), reacts accordingly to the speed and pressure of a door closure.
  • the reaction from the engineered material effectively responds to the user input intelligently. Accordingly, higher pressure and/or speed of the door swing results in more resistance by the device to closure, while lighter pressure and/or slower speed results in a more normal door closing experience. Also, adjustability of the device allows for more resistance more quickly as well as full lock out capability, such that the door will not be able to close.

  • Figure 8 is a cross-sectional top view of the install guide of Figure 6 in a doorjamb according to an embodiment of the present invention.
  • a head unit 100 is defined as a generally cylindrical device as shown in Figure 1, with adjustable valving filled to a specific volume within a channel 15 with a shear thickening fluid (or dilatant fluid), the device assembled to resist leakage or disassembly.
  • the system has at least two parts - the head unit 100 (shown in Figure 1) and a strike 14 (shown in Figure 2).
  • the head unit 100 is installed in, by way of example, a hole with a diameter of
  • the head unit 100 can be installed with an install kit including an install tool or guide 20, disclosed with respect to Figures 6 through 8. As shown in Figure 1, the strike 14 is installed into, by way of example, a hole with a diameter of 15/16” and 1 ⁇ 2” deep, which is drilled into the door edge ( e.g ., the jamb side) to provide a contact point for a plunger cap 3 of the head unit 100, as shown in Figure 2.
  • shear thickening fluid provides the“brains” that allow a slotted piston head 9 with an adjustable shim stack style valve to close onto the piston head 9 resulting in a controlled close.
  • Shear thickening fluid (or dilatant material) is a Non-Newtonian fluid that stiffens when acted upon by pressure and/or speed. For example, the greater the speed and/or pressure, the stiffer the fluid becomes. When the speed and/or pressure is light, the fluid is flowable. When the speed and/or pressure is higher, it begins to act more like a solid.
  • Example components of an embodiment of the present technology are as follows:
  • the Head Unit or Adjustable Assembly 100 (shown in Figure 1)
  • the components of the Head Unit 100 are as follows:
  • the system also includes a Strike (14) (shown in Figure 2) and Shear Thickening Fluid (15) (shown in Figure 1). Relationship between the Components:
  • a plunger 5 is inserted, (non-flange end) through, by way of example, a 0.25” hole in a plunger bushing one piece 4.
  • a spring 8 is inserted into a larger diameter cavity in the plunger bushing one piece 4.
  • the plunger cap 3 is inserted onto the non- flange end of the plunger 5 with the spring 8 settling into a cavity of the plunger cap 3.
  • the piston head 9 is placed on the flange side of the plunger 5, and the rebound guide plug 7 is inserted into the drilled hole in the flange end of the plunger 5.
  • the hydraulic chamber 1 is filled with shear thickening fluid 15.
  • shear thickening fluid 15 approximately 7.5 grams may be used.
  • the volume that contains the shear thickening fluid 15 is hereinafter referred to as the Hydro Chamber.
  • the Subassembly can then be inserted into the Hydro Chamber vertically.
  • the retaining ring 13 is squeezed to allow it to enter the Hydro Chamber, and then the Subassembly is pressed in until retaining ring 13 snaps into place into a groove in the interior of the hydraulic chamber.
  • the jamb collar 2 is then placed on the plunger bushing one piece 4 aligning the tabs on jamb collar 2 with the recesses on the hydraulic chamber 1 and pressed in place. [0022] The resulting device is the head unit 100 and it is a permanent assembly.
  • the Head Unit 100 can be lightly hammered into a drilled hole in the jamb side of the door, such as by employing an install guide 20, which is discussed further with respect to Figures 6 through 8.
  • the strike 14 (shown in Figure 2) can be lightly hammered into a drilled hole on the door edge side. Drilling of this hole is also done by use of the install guide 20.
  • the plunger cap 3 can contact the door directly without the use of a strike while retaining the benefits of the systems and devices disclosed herein.
  • a strike can be configured with a recessed cavity rather than a flat surface, such that the plunger cap 3 is inserted into the cavity before making contact with the strike.
  • a strike may be a plate on the surface of the door edge opposite the plunger cap 3.
  • the head unit 100 is inserted into a hole drilled into the jamb side by tapping (lightly hammering) the head unit 100 into the cavity with the install kit.
  • the strike 14 is inserted into the door edge by tapping (lightly hammering) the strike 14 into place in the drilled hole.
  • the plunger cap 3 of the head unit 100 contacts the edge of the door, such as at the strike 14, which depresses the plunger cap 3 such that the plunger cap 3 pushes against the plunger 5 and spring 8 and such that plunger 5 is pushed through plunger bushing 4. That action leads to piston head 9 and shim 6 on guide plug 7 moving with respect to fluid 15. Fluid 15 reacts to the force and speed of that impact and stiffens up accordingly or remains flowable depending on the force applied.
  • shim 6 has one or more slots 18 that generally match one or more slots 19 through piston head 9 in one or both of size and/or shape.
  • the ability of the fluid 15 to resist the force of the depressed plunger cap 3 (and thus control the speed and/or force of the door closure) depends on the alignment of the slots 18 of the shim 6 and the slots 19 of the piston head 9.
  • Piston head 9 has a stop built into it such that guide plug 7 contacts in both the left and right rotations to adjust the amount of fluid 15 compression.
  • the slots 18 on shim 6 have been rotated to the left ( e.g ., by the user via a simple turn of plunger cap 3), then the slots 18 on shim 6 will not align with the slots 19 in piston head 9 and, thus, the fluid 15 will resist the movement of the piston 5 and the plunger cap 3, and the plunger cap 3 will not depress and the door will not close ( i.e . partially, completely, and/or more slowly, depending on the resulting alignment).
  • Fluid 15 also serves to control, in combination with the selection of the spring rate of spring 8, the return force from cap 3 so that it does not push the door open or allow the door to aggressively bounce back at the user.
  • the force on the door from cap 3 can be adjusted to a desired level to provide for a controlled opening by gently pushing the door open, such as by unlatching the door (either remotely, electronically, manually or otherwise).
  • the shim 6 is rotatable such as by a user (and thus the position of the slots 18 in the shim 6 with respect to the slots 19 in the piston head 9) by rotating the plunger cap 3.
  • the plunger cap 3 is tightly fitted to the plunger 5, which is tightly fitted to the guide plug 7, which is tightly fitted to the shim 6. Therefore, rotation of the plunger cap 3 causes the plunger 5 to rotate, which in turn causes the guide plug 7 to rotate, which in turn causes the shim 6 to rotate, allowing adjustment of the amount of compression ( i.e . resistance) experienced during closure.
  • the slots 19 of piston head 9 are pitched with the wider part of the opening facing the fluid 15 and the narrower part on the backside of the piston head 9 such that the slots 19 are substantially“V” shaped.
  • the shear thickening fluid 15 stack up (stiffen) as the piston 5 pushes through the fluid 15 upon the closing/slamming of a door closure.
  • the shear thickening fluid 15 as engineered, has nanoparticles of a specific dimension that are mixed in a non-toxic carrier fluid or solvent. Force applied to the shear thickening fluid 15 results in these nanoparticles stacking up, thus stiffening and acting more like a solid than a flowable liquid. Examples of shear thickening fluid are disclosed in U.S. Pat. No. 7,825,045, which is incorporated herein in its entirety by reference.
  • the particles of shear thickening fluid 15 may be, by way of example, oxides, calcium carbonate, synthetically occurring minerals, naturally occurring minerals, polymers, or a mixture thereof.
  • the particles may also be, by way of example, Si0 2 , polystyrene, or polymethylmethacrylate.
  • the solvent may be, by way of example, water, which may contain salts, surfactants, and/or polymers.
  • the solvent may also be, for example, ethylene glycol, polyethylene glycol, ethanol, silicon oils, phenyltrimethicone or a mixture thereof.
  • the particles may have an average diameter size that is less than 1 millimeter, and may have an average diameter size of less than 100 microns.
  • the shear thickening fluid 15 may be made of silica particles suspended in polyethylene glycol.
  • silica particles may suspended in the polyethylene glycol at a volume fraction of approximately 0.57.
  • the silica particles may have an average particle diameter of approximately 446 nm.
  • the fluid may have a shear thickening transition at a shear rate of approximately 102-103S-1.
  • a simple rotation of the plunger cap 3 allows the user to control the valve sensitivity based on the feel they want when closing the door. Turning left to the stop locks out the device so that that door cannot be closed at all - even gently - because the shim 6 attached to the piston head 9 completely blocks the slots 19 of the piston head 9 from allowing any shear thickening fluid to pass through. Turning the plunger cap 3 to the right allows the device to let the door be closed normally ( i.e ., gently closed and not slammed) because the slots 18 on the shim 6 are generally aligned with the slots 19 on the piston head 9, allowing the fluid to pass through. However, the fluid still reacts to speed and pressure. Therefore, the system still controls the door closing to resist a slam.
  • the shim 6 is held in place by a cylindrical stainless steel rebound plug 7, with a flat section (shown in Figures 4A-4C) that fits into a“D” shape in the shim 6 (shown in Figure 3), keeping it in position for the user adjustment and alignment of its slots 18 with the piston head 9 slots 19.
  • the shim 6 floats on the rebound plug 7, such that the shim 6 is not in a fixed position in the direction of the plunger 5.
  • the shim 6 presses against the piston head 9 when the shear thickening fluid 15 is being compressed, and pulls away from the piston head 9 on rebound of the door, allowing the piston head 9 slots 19 to be fully open.
  • the piston head 9 is attached to the plunger 5 that is attached to the plunger cap 3 (the plunger cap 3 is the component that contacts the strike 14 on the door edge).
  • the spring 8 returns the plunger 5 to its fully extended position with the combination of the selected spring rate and the engineered shear thickening fluid 15 controlling the rate of return, thus not allowing a spring- back effect.
  • the plunger bushing one piece 4 serves as a guide for the plunger 5 and the plunger cap 3, and as a stop for the spring 8.
  • the plunger bushing one piece 4 has one or more grooves for at least O-rings 10 and 11 used to seal the hydraulic chamber 1 as well as the plunger rod/bushing interface.
  • jamb collar 2 is slip fitted onto the outermost section of the one-piece plunger bushing 4 that protrudes from the hydraulic chamber 1.
  • the exterior or“face” of jamb collar 2 becomes flush with the jamb edge when the head unit 100 is inserted and tapped (lightly hammered) into the drilled hole in the doorjamb that receives the head unit 100.
  • This jamb collar 2 component function is three-fold. First, the jamb collar 2 holds the device securely in the doorjamb. Second, being slip fit on the bushing 4 gives the remainder of the device that is inside the doorjamb framing the ability to be disconnected from the doorjamb itself (because it is free to move slightly fore-aft inside the jamb collar), thus not pulling on the jamb millwork and stressing/flexing the jamb and hinges. And third, the jamb collar 2 is a finished face to the drilled hole where the head unit 100 is inserted.
  • the strike 14 may be manufactured from one or more engineered materials, such as polymers and/or thermoplastics with high stiffness and stability and low friction.
  • polyoxymethylene such as Delrin or Acetyl
  • the composition allows the plunger cap 3 to contact and slide against the strike 14, yet without catching or sticking to the surface during door closure.
  • the disclosed technology provides a way to control door slamming and closure.
  • it can protect fingers from door slams (toddlers, young children), prevent unwanted aggressive door closures such as those done by teenagers or adults hastily closing doors, and prevent wind driven door slams. It can prevent a door from closing on pets, toddlers, or the elderly, who may have a tendency to accidentally close a door, locking themselves in a room.
  • the disclosed technology also includes an installation kit, shown in Figures 6 through 8, which can be used to install the head unit 100 and/or strike 14 into a jamb and door edge, respectively.
  • the install tool assists in exactly locating the position of both the head unit 100 on the jamb and the strike 14 on the jamb side door edge, as well as controlling the depth of the drilled cavities into which the head unit 100 and strike 14 are installed.
  • the install kit includes an install guide 20 (shown in Figures 6 through 8 and which can be molded from materials such as Delrin/ Acetyl), a drill bit 30 (shown in Figures 7 and 8) (alternative bits can also be employed), and the drill bit 30 bushing can be revised to fit alternative bits), a drill bit bushing 40 (which can be molded or CNC machined from materials such as Delrin (Acetyl)), a drill sleeve 50 (which can be CNC machined from PVC Rod or Delrin Rod), and/or a locking collar 60 (shown in Figure 8).
  • an install guide 20 shown in Figures 6 through 8 and which can be molded from materials such as Delrin/ Acetyl
  • a drill bit 30 shown in Figures 7 and 8 (alternative bits can also be employed), and the drill bit 30 bushing can be revised to fit alternative bits
  • a drill bit bushing 40 which can be molded or CNC machined from materials such as Delrin (Acetyl)
  • the head unit 100 and the strike 14 and then insert the head unit 100 into the jamb and insert the strike 14 into the jamb side of the door.
  • a user can then adjust the head unit 100 as desired by turning plunger cap 3 left or right or in between as desired to control door closure and react to speed and pressure of closure.
  • the closing door meets less resistance from the head unit 100 and the door closes easily, whereas at higher speed and pressure the head unit 100 stiffens up and controls the slam.
  • the install kit is used as follows. To drill a hole for the head unit 100 in the doorjamb, a screw is removed from a hinge and placed into a screw slot in the guide 20 and tightened back up in the hinge screw hole with the tool/guide 20 held tightly to the edge of the doorjamb stop to stabilize the guide 20 on the jamb and locate the hole to be drilled for the head unit 100.
  • the bushing 40 is placed on the bit 30 and held in place by the collar 60, which is tightened with a set screw on the collar 60.
  • the install kit can come with bushing 40 and collar 60 already installed on bit 30. This is called the Drill Bit Assembly.
  • the user can drill into the jamb edge through, by way of example, an approximately 0.950 inch hole in the guide 20.
  • the assembly of the drill bit 30, guide 20, collar 60, and bushing 40 is shown in Figure 8.
  • the Drill Bit Assembly’s drilling is stopped by the flange on the bushing 40 contacting the top of the guide 20, the Head Unit hole drilling is complete.
  • the drilling process for the doorjamb using the guide 20 is illustrated in Figure 8. The guide 20 is then removed from the jamb by removing the screw holding it in place.
  • the screw from the matching location on the other half of the hinge on the door edge side is removed and the guide 20 is centered on the door edge and the screw is used to secure the guide 20 to the door edge.
  • Drill sleeve 50 can then be put onto the drill (from the cutting side) and slid up until it contacts the flange on the bushing 40.
  • the process of drilling into the door edge is then similar to that described in drilling the jamb side for the head unit 100, however the drill sleeve 50 will now contact the guide 20 when the drilling is complete, creating a, for example, 1 ⁇ 2” cavity in the door edge for the strike to be installed.
  • the head unit 100 is now pushed into the hole in the jamb and the blind hole in the bottom of the guide 20 is placed over the plunger cap 3 of the head unit 100.
  • the head unit 100 is then lightly hammered into the jamb by tapping on the most raised portion of the guide 20.
  • the head unit jamb collar 2 is flush with the jamb and the head unit 100 is securely installed in the doorjamb.
  • the strike is then lightly hammered into the cavity on the door edge side, securing it in place.
  • This install guide 20 assists in aligning the drilled holes on the door edge and on the jamb with each other when the door is closed, such that the head unit 100 and the strike 14 line up with each other when installed.
  • the install guide 20 also helps in making sure that the depth of the drilled holes is correct so that the head unit 100 is level and at the corrected depth when installed and that the strike 14 is level and at the correct depth when installed.
