  • Figure 1 is a side view of a "D" type door handle 11 which has been modified to form a modified door handle assembly 12 according to the present invention by installation of a discrete unit wrist door pull 13.
  • the door handle is designed to be preferably gripped at a center portion 15 to open a door 17.
  • the wrist pull 13 also permits a user to open the door 17, but does not require the user to engage the handle 11 with the user's hand.
  • Door pull 13 includes a substantially horizontal portion 21, a flared portion 23, a base portion 25 and an end portion 27.
  • the horizontal portion 21 extends outwardly from door 17 and extends from a base portion 25.
  • the flare portion 23 extends from the horizontal portion 21, and terminates in end portion 27.
  • Horizontal portion 21 and the flare portion 23 form a resting surface for the user's arm or wrist, so that the user is able to pull outward on door 17. This permits opening of the door without gripping "D" handle 11.
  • the invention permits a user to open a rest room door 17 without touching the "D" handle 11.
  • a wrist door pull 13 provides a convenient mechanism for doing so the wrist door pull 13 is contoured to fit to the wrist or lower arm so that the opening and use of the door is comfortable and people would use it without potential harm to themselves.
  • the handle avoids harm from unintended forces between the door and user. As an example, if someone were to push on the door at the wrong time on the opposite side of the door, the wrist would not be caught or pulled away. The user's wrist slides off and no harm is done.
  • door pull 13 is described in terms of "opening” the door 17, it will be understood that door pull 13 can also be used to pull a door closed. Anybody who still wants to open with their hand would tend to use the "D" handle 11 as to pull open the door, as the wrist operated extension to the door handle is not comfortable to be used as a knob in view of the extended diameter of end portion 27.
  • Door pull 13 is designed so that if a user wants to use their hand it is still much more convenient to use the "D" handle 11 than it is to grab wrist door pull 13 at the end 27 so thereby reducing the number of germs that get transmitted. People would naturally not use the wrist door pull 13 as a pull but use only their wrists or forearm. This minimizes the amount of their germs on top end 27.
  • door pull 13 is designed to accommodate the wrist or lower arm of a child up to a fairly sizeable man without being uncomfortable for any of them.
  • Horizontal and flared portions 21, 23 have outer surfaces 41, 43, respectively joined by upwardly rounded surface 18.
  • the radius of surface 18 of door pull 13 is such that a man's wrist would not go as deep as the radius size of a woman's wrist. By the same token, the user can turn his wrist slightly so that handle 13 itself feels comfortable.
  • the typical pulling motion is not only pulling straight towards the user, but the user usually pushes down at the same time to the extent of obtaining gripping force. If the user were to just pull towards the user, the user's wrist or arm ordinarily would tend to slip off smooth surfaces 41, 43. By pushing down and towards the user, the arm is kept in position on handle 13 and the user is able to open the door more easily.
  • the wrist 20 or forearm position is depicted in Figure 1 and in detail in Figure 1A.
  • the operation of the door pull 13 allows a person to exert downward force (F y ) 200, as well as horizontal force (Fx) 202.
  • the horizontal force exerted on the door must be equal to, or greater than, the force necessary (FDOO ⁇ ) to open the door. Any horizontal force greater than FDOO ⁇ will cause the door to accelerate. No acceleration will be used in the calculations below, but this may not appreciably effect the results obtained.
  • ⁇ s may be approximately 1-1.7 and horizontal force would only be necessary for an angle of 45°-30°, respectively, for example.
  • a downward force must be applied in addition to the horizontal force to prevent the wrist with sleeve 20 from slipping along the top surface 43 and, therefore, the total force necessary to open the door is greater than for angles greater than, or equal to, ⁇ max.
  • Safety considerations though, suggest that a smaller angle is desirable. Preferred angles are later described. It is also noted that the minimum ⁇ s , and therefore ⁇ max, is not readily determined.
  • Equation (2) shows the minimum downward force needed to avoid slippage for top surface angles ( ⁇ ) less than ⁇ max.
  • FApphed FDoorCSC( ⁇ ) (3)
  • the applied force would be applied directly into the top surface of the door puller.
  • this situation represents the maximum force that would be required to open the for a given angle of top surface 43.
  • the angle (theta) is selected so that the minimum vertical force F y (minimum) to keep the arm on the flange is within reasonable limits, but yet is significant to cause the arm to be deflected if the door pull 13 is accidentally engaged or the horizontal force Fx becomes excessive. If the door handle 13 is accidentally engaged, the user is not likely to exert significant vertical force F y . This results in the arm sliding up the flanged portion and releasing the arm. This could happen in two cases:
  • the user would simply be deflected by the flanged portion as a result of not exerting a deliberate amount of downward force F y .
  • the user would either intentionally release force on the door or the force in the horizontal direction would result in the user's downward force becoming insufficient to retain the user's arm in position on the flanged portion 23. In either instance, the person's arm would simply slide off the door handle 23.
  • the door is opened by another person or by an automatic mechanism.
  • the force would urge the door toward the user, and the inventive door pull would not be pulling against the user.
  • the door pull 13 in which the portion 21 is of generally cylindrical shape forming an open cylinder at the bottom as best shown in Figure 2D.
  • This door pull 13 is non-symmetrical compared with a conventional rotating door pull.
  • Door pull 13 preferably is also non- rotatable. Outside surface 41 forms the outer surface of the cylindrical shape. This continues from portion 21 at a distance 12 from a door abutting surface 26 of end boss 25.
  • the door pull 13 slopes upwardly through rounded surface 18 forming flange 23 (generally open conical shape), by a sloping outer surface 43 ending at a rounded outer surface 45.
  • the open cylinder and open conical shape as best shown in Fig.
  • FIG. 2D are adapted to receive the upper portion of "D" handle 15.
  • This upwardly sloping surface 43 is, in its most preferred value, 36° ⁇ 10% with respect to longitudinal axis 29, as shown in Figure 2A.
  • portion 21 is closed by an end portion 27 having a most preferred radius of 1.3 inches from the axis 29.
  • surface 43 on both sides 53a, 53b of the door pull is approximately 25° + 10% (most preferred value) with respect to axis 29.
  • Portion 21 is preferably long enough that the wrist or forearm of a large person is able to rest on surface 43 while partially resting on surface 41.
  • the hand automatically rotates around the outer surface of the door pull 13 and the angle of the sloping surface with the user decreases from 36° to 25°. This makes it easier for the wrist to disengage.
  • End 27 angles from rounded edge 45 by approximately 6° from the horizontal for the purpose of molding of the wrist door pull 13.
  • End 27 may have a 1.3" radius as illustrated. It will be understood that end 27 may carry a logo of a franchise for example or other wording, such as "Exit”.
  • Pull 13 may be made of any suitable material, such as ABS plastic or metals, such as aluminum, nickel or brass.
  • the length 12 of surface 41 from surface 26 is approximately 1.7 inches (most preferred).
  • the total length of the wrist door pull 13 may be 3.3 inches (most preferred). Distance 1.7 inches is for the purpose of being universal to existing "D" handles 11 or 31 to which the wrist door pull 13 is attached in Figures 1 and 3.
  • FIG. 2E there is shown the end boss 25 of the door pull 13 that is adapted to engage door 17 and or a plate on the door 17 such as metal door plate 53.
  • the end surface 26 has an opening 54 for receiving a screw 55, which in the preferred embodiment is a l A inch machine screw or bolt.
  • surface 41 is cylindrical up until a longitudinal section 49 where surface 41 becomes a tangent at 53a and 53b for approximately .56" (14mm) thereby forming flats on either side of surface 41.
  • Side surfaces 53a and 53b may have a ratio of 1:3 width to length.
  • spacer 65 Details of the spacer 65 are shown in Figures 4A and 4B. Essentially the spacer 65 is a thick washer which is shaped so as to provide an appearance which is aesthetically compatible with the wrist pull 13 and which has a fit suitable for most "D" handles. Referring to Figures 1 and 3, spacer 65 is positioned with respect to the lower end of "D" handle 11 or 31 and respective screws 55, 55A,B are then installed.
  • end boss 25 with a taper at an angle which would result in the lower part of the "D" handle 11 or 31 aligning with the surface of the door 17 or plate 53. This would skew the "D" handle 11 or 31 sufficiently to avoid the need for a spacer 65.
  • Top and bottom screws 55 A, 55B are depicted in Figure 3. Bottom screw 55B extends through door 17 while upper screw 55A is only secured to the metal door plate 53. It is clear that the particular configuration of the screw attachments are able to match that of an unmodified "D" handle 11 or 31.
  • surface 43 may have a most preferred angle ⁇ with axis 29 of 36° +3.6° (a range of + 10%) sufficient to permit proper force outward and downward to open door 17. It is possible to vary this angle to +7.2° (+20% range) in a preferred embodiment of the invention, and + 10.8° ( + 30%) in a less preferred embodiment of the invention.
  • the side surfaces 61A, 61B may be 25° ⁇ 2.5° ( + 10%) (most preferred range) to permit the left or right wrist to slip off. It is possible to vary this angle to 5° (+20% range) in a preferred embodiment of the invention, and 7.5° ( ⁇ 30% range) in a less preferred embodiment of the invention.
  • the inner radius of portion 21 may be about % inch most preferred and of increased radius in its preferred value. Lesser radius are less preferred with V 2 inch radius being the least preferred.
  • the most preferred value is about 1.7 inches. As this value is decreased, it becomes more difficult to accommodate all wrists and particularly forearms. Thus, 1.7 inches minus 30% range remains in a preferred range. As this value is increased, however, door pull 13 may become an obstruction. Thus, a less preferred value of length 12 may be about 2V 2 inches.
  • FIGs. 1 & 3 door pull 13 may be fixed directly to door 17 without use of D handle 11 or 31.
  • Figures 5-7 show variations on the discrete unit door pull 13 of Figures 1-3 without use of D handle 11 or 31 in Figs. 1-3.
  • Figure 5 is a top view of door pull 71 in which a cross-hatch design 73 is formed on a top surface 75.
  • the top surface 75 is produced from a separable mold insert (not shown) so that variations on the top surface 75 are easy to manufacture.
  • a door pull 81 is shown with a plurality of ribs 83 on a top surface 85.
  • the plurality of ribs 83 are formed normal to a direction of pull by the user.
  • the ribs 83 present (1) an aesthetically pleasing gripping surface, (2) provide more friction with respect to the wrist or forearm, and (3) make it comfortable on the user to exert outward force to open the door with the wrist or forearm.
  • the ribbed pull 81 shows a preferred form of the invention, particularly in view of the increased friction. Friction may also be increased in other embodiments by providing a rough texture on surfaces 41, 43, Fig. 1, as by sand blasting the surface.
  • FIGS 7 A and 7B are top and side views of a discrete unit door pull 91 having a different configuration from that of discrete unit door pull 13.
  • Flanged portion 83 slopes upward from portion 85 at a preferred angle of 36°, but the sides 87 extend at angles which are less than that of sides 61 A, 6 IB, Figures 1-3.
  • end surface 89 is substantially flat.
  • Figure 8 is a side view of a unitary handle 101 which combines the functions of a "D" type door handle and wrist door pull.
  • the handle includes a door pull section 103 and a "D" type door handle section 104.
  • the door pull section 103 and a "D" type door handle section 104 are formed as a single assembly.
  • the assembly 101 is mounted at upper and lower mounting locations 105, 106.
  • This assembly 101 replaces or is installed in lieu of a conventional "D" type door handle and presents a more aesthetic appearance than that obtained by using a discrete unit wrist door pull.
  • the dimensions of the door pull section 103 are substantially similar to those of the discrete unit wrist door pull 13 of Figures 1-3, except that the end boss (25, Figures 1-3) is combined with the upper mounting location 105 for the "D" type door handle section 104.
  • Figure 9 is a side view of a unitary one-piece handle 111 which combines a "D" door handle and door pull. This embodiment presents a "D" door handle integrating a wrist door pull. An outwardly projecting fairing 113 extends from a handle grip 114 to a wrist pull 115.
  • Figures 10 and 11 are elevation views of stylized door pulls 121 and 123.
  • the door pull 121 of Figure 10 depicts a simple curved appearance, which reduces a "cluttered” appearance by integrating the curves of the hand grip section 125 and wrist pull section 126. It is noted that it is not necessary to have a sharp break between the substantially cylindrical portion 128 and the flanged section 129.
  • the door pull 123 of Figure 11 has a lower protrusion 133 extending from a hand grip section 134. This permits intentionally catching the door pull 123 from beneath the grip section 134.

In many cases, these portions of the body are clothed. In addition, regardless of the contamination level, if contamination is limited to a person's arms, it is less likely that that person could then contaminate food or other items which are handled by that person. Therefore, if the person engaged in hand washing prior to using the door, recontamination would be less likely to occur.
