Handle for door closing

Abstract

Improvements handle for door closing is disclosed. The handle is rotatable from an outer housing that both protects the handle and provides a structural frame for mounting the handle to a pre-existing door. A typical installation is to place the handle closer to the hinge side of the door. This allows a user to require a shorter reach and pull to the door. Because opening a door for a wheelchair requires the door to almost be completely opened. The handle also has a rotation stop that prevents the handle from being rotated out of the housing more than 90 degrees. A retention and extending mechanism both holds the handle within the housing and slightly opens the handle for a user to grasp. The housing can be surface mount or flush mount. The handle can allow for weight bearing support of a user.

(11) FIG. 1 shows a handle for door closing 20 in an environment of use. This figure shows a typical use where the person 18 in the wheelchair has passed through the doorway and is essentially clear of the door 19 swing. The knob 17 for the door 19 is clearly out-of-reach for the person 18 in the wheelchair. The handle 20 is placed closer to the hinge of the door 19 and can be easily reached to grasp and pull the door closed. The handle 20 on the door 19 is restricted from rotating beyond about 90 degrees to prevent pinching the fingers or hand and to provide support. With the handle 20 essentially perpendicular to the door 19 the person 18 can essentially pull the handle 20/door 19 straight towards them at an optimal force. After the door 19 has been closed the handle 20 can be rotated into the housing and essentially parallel to the outer surface of the door 19.

(12) FIG. 2 shows a handle for door closing 20 in a first preferred embodiment. This figure shows the handle 60 extended from the body of the handle for closing a door 20. The handle 60 fits within the pocket 42 which allows the handle 60 fit flush with the face surface 40 The handle for a door 20 is secured and retained in a door with screws or other hardware by being placed through screw hole 44. The handle 60 pivots from the body through rotational axle 62 and the rotational arc 90 is shown. In this embodiment the handle for a door 20 is configured for flush mounting into a door.

(13) To mount the handle for a door 20 into a pre-existing door a pocket must be cut into the door to accommodate the outer recess 45. An additional pocket can be milled into a door to accommodate the lip 41. Once the handle for a door 20 is placed into a door the entire top surface of the handle for a door 20 is flush, to allow a user to grasp the handle 60 it must be at least slightly extended from the face surface 40. A magnetic clasp retains the handle 60 within the pocket 42. To obtain an edge of the handle 60 to lower the handle 60, a user pushes the handle 60 down into the housing. The magnetic pusher 51 extends the portion of the handle 60 from the surrounding face surface 40. The bottom of the magnetic pusher 51 extends behind the housing with a pusher stud 51 that further extends into the door. This provides an edge of the handle 60 to fully deploy the handle 60 by following the rotational arc 90.

(14) Within the pocket 42 there is a rotational stop surface 43 that prevents over-rotation of the handle 60. The rotation 90 of the handle from the housing is essentially 90 degrees, but other angles are contemplated to nearly 150 or more degrees. The handle 60 is secured to the body with a pin, a roll pin, or other member that provides equivalent function. The roll pin provides sufficient strength to use the handle as a support to assist in lifting or supporting body weight and from side loads 102 on the handle 60 to move the door 19. After use the handle 60 is rotated 90 degrees back into the housing where the magnet portion of the magnetic pusher 51 nests within the pocket 61 with the metal plate inside and secured with a press-fit or with an adhesive such as epoxy.

(15) FIG. 3 shows a handle for door closing 21 in a second preferred embodiment and FIG. 4 shows a side sectional view of the second embodiment. This second embodiment is similar to the previous version shown and described. In this second preferred embodiment the handle for a door 21 is configured for mounting on an exterior surface of a door. There is no exterior lip to limit how far the body of the handle for a door 21 is placed into a door, but the handle for a door 21 can be placed into a milled or routed recess or pocket. The handle for a door 21 is mounted on the door with fasteners or screws placed through the screw holes 44. The roll pin 63 is shown passing through the side of the outer housing 70 and the handle 60. This allows for rotation of the handle 60 as the handle follows the rotation arc 90 and pivots on rotation axle 62. At the end of the travel of the handle 60 the bottom of the handle 60 is shown contacting the rotation stop surface 43 that limits further rotation of the handle 60.

(16) Within the housing is a pocket with a spring 71 that pushes the handle 60 out of the housing. The handle 60 is retained flush with the housing with a latch tab 73 that engages in a lock recess 64 on the end of the handle 60. The latch tab 73 is on a pivoting latch 72. The pivoting latch 72 is maintained in position with a biasing spring 75. The pivoting latch 72 pivots on roll pin 74. A user presses on the bottom of the pivoting latch 72 to rotate 91 the latch. The rotation 91 of the latch 72 will pull the latch tab 73 from the lock recess 64. The spring 71 will then push one end of the handle 60 out of the outer housing. A user can then lift the end of the handle 60 and pull on the handle 60 to pull a door closed. After user, the user can push on the handle 60 to rotate the handle 60 into the housing. The end of the handle 60 is sloped to push open the pivoting latch and the lock recess 64 will fall into the latch tab 73 to retain the handle 60 in the closed condition where the outer surface of the handle 60 is flush with the face surface of the housing.

(17) FIG. 5 shows a handle for door 22 closing in a third preferred embodiment, FIG. 6 shows a detail of the latch 81 and FIG. 7 shows a detail of the slide tab 85 mechanism. The handle 86 rotates from the outer housing 80 with a roll pin 63 or similar mechanism on rotational axle or axis 62. This allows the handle 86 to sing in the rotation arc 90. This third preferred embodiment is similar to the second preferred embodiment with the differences being the mechanism that retains the handle 86 within the outer housing 80.

(18) This embodiment of the handle for door 22 allows the handle for door 22 to be recessed into a door and does not require access to the from of the housing to release the handle 86. A user can press on the top of the handle 86 to eject the front edge of the handle 86 and can push the handle 86 back into the housing to secure and store the handle 86. In the first embodiment 20 the magnetic retention mechanism extended beyond the bottom of the housing, whereas in this embodiment of the handle for door 22 the portion of the retention and rejecting mechanism is integrated with the handle 86 and in the front of the outer housing 80.

(19) FIG. 7 shows a detail of the slide tab 85. The slide tab 85 is restrained in a housing with two springs 79 that center the slide tab 85 within the slide housing 84. The slide tab 85 can be pushed side-to-side 92 within the slide housing 84 and the springs 79 will center the slide tab 85 in the slide housing 84 as shown in FIG. 5. The mechanism is configured to be inserted into a slot in the handle 86 where it is retained with pins 78 or other securing hardware. FIG. 8 shows a detail of the latch 81 where the slide tab 85 engages and interacts.

(20) The latch is integrated or formed on the front hosing 82. The latch 81 has two integrated moon shapes where the slide tab 85 slides around the latch 81 to retain and eject the slide tab 85 to hole the handle 86 within the outer housing 80. While the latch 81 is shown proud from the front housing 82 it is also contemplated that the latch 81 can be recessed to provide the path for the slide tab to follow. The operation of the latching mechanism is shown and described in other figures herein.

(21) FIG. 8A-8C shows the operation of the latch. As previously described the slide tab 85 can move side-to-side 92 within the slide housing 84. In FIG. 8A the slide tab 85 on the handle 86 (not shown) is being brought down 93 into the latch 81. The slide tab 85 is centered in the slide housing 84 with springs 79. As the slide tab 85 is brought down 93 into the latch 81, the slide tab 85 will slide down the right side of the top edge 87. This will push the slide tab 85 across 94, within the slot 88. The slide tab 85 will be pushed across 94 until the slide tab 85 reaches the bottom edge 89 of the latch 81. At this point, the spring 79 will push the slide tab 85 to slide under the latch 81. When the downward force 93 is no longer applied the underside of the latch 81 will retain the slide tab 85 in a closed position where the handle is flush with the top surface of the outer housing.

(22) Referring back to FIG. 5, there is a recess pocket 83 that allows the leading edge of the handle 86 to be pressed into the outer housing. In FIG. 8B this motion is shown and described with the down 97 force. This force will cause the slide tab 85 to slide down 98 the face of the latch 81 where the slide tab 85 will move across 99 the latch and under the bottom edge of the latch 81. The spring will then re-center the slide tab 85 and will push the slide tab 85 around 100 the latch 81 as shown in FIG. 8C and will push the slide tab 85 (and the handle 86) up 101 to expose the front edge of the handle (not shown). The entire sequence can then be repeated to use and store the handle within the outer housing.

(23) Thus, specific embodiments of a handle for door closing have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
