DETAILED DESCRIPTION OF THE INVENTION
(22) Referring to the accompanying drawings wherein like reference numbers refer to the same or similar elements,
(23) The first and second arms 12, 14 are movable between the first and second states, but in use are preferably locked in the second state to prevent movement of the first and second arms 12, 14 from the second state to the first state and thus, when the first and second arms 12, 14 are around the door lever 6, maintain the first and second arms 12, 14 around the door lever 6 (
(24) When the lockbox 4 is secured to the apparatus 10 as shown in
(25) Aperture 16 can be formed by the first and second arms 12, 14 in a variety of different ways, whether by a recess in only one of the arms 12 or 14 or by recesses in each arm 12, 14. As also disclosed below, the aperture 16 may be formed or defined by additional structure that enables its size to be adjustable. In the embodiment illustrated in
(26) Each recess 20, 26 has a generally semi-circular cross-section in the depth direction of the respective member but its shape can vary and is not limited to being semi-circular or even uniform in the depth direction of the first and second arms 12, 14. Recesses 20, 26 have a shape relative to one another to form the aperture 16 with a cylindrical form, but this is not a required feature and may vary for different embodiments. Head portions 18, 24 are therefore provided with a curved form.
(27) The bottom portion 22 of the first arm 12 has an upper end region integral with the head portion 18, but may alternatively be connected thereto if formed from separate members. The bottom portion 28 of the second arm 14 has an upper end region integral with the head portion 24, but may alternatively be connected thereto if formed from separate members.
(28) The structure that maintains the first and second arms 12, 14 in the second, closed state and prevents their movement from the second, closed state (
(29) The engagement means may be formed on only the first arm 12, only the second arm, or partly on both of the first and second arms 12, 14. The engagement means may be intrusive in that they require contact with only the first arm 12, only the second arm 14 or with both the first and second arms 12, 14. The specific engagement means illustrated in this application do not limit the scope of the claims.
(30) In one embodiment, the engagement means comprise a generally U-shaped staple 30 in the bottom portion 28 of the second arm 14, and a slot 32 in the bottom portion 22 of the first arm 12 that is dimensioned to allow the staple 30 to pass therethrough. In this embodiment, the first arm 12 is in front of the second arm 14 when the first and second arms 12, 14 are in the closed state since it is better to have an exposed part of the staple 30 in front of the apparatus 10 to enable easy insertion of a shackle of a lock or lockbox through the opening of the staple 30 (the front being the side intended to be facing away from the door). Nevertheless, the staple 30, the slot 32 and the first and second arms 12, 14 could be configured such that the opening of the staple 30 is on a different side of the apparatus 10. The same variation may be made to the other embodiments of the apparatus 10 disclosed herein.
(31) The staple 30 generally may also be considered a support for a lockbox and more specifically a support for a shackle of a lockbox.
(32) The staple 30 has elongate, parallel legs connected to the bottom portion 28 and a curved portion connecting the legs extends in a direction toward the first arm 12 (
(33) To enable the staple 30 to pass through the slot 32, the bottom portion 22 of the first arm 12 is provided with a slotted part 34 connected to a base part 36 by a hinge 38 (
(34) The staple 30 is passed through the slot 32 by, from when the first and second arms 12, 14 in the first, open state around the door lever 6 (
(35) When the first arm 12 is raised and the slotted part 34 is positioned and lowered over the staple 30, the first and second arms 12, 14 align one behind another and cannot spread out. In this position, the apparatus 10 is unable to open and slide off of or be removed from the door lever, or door knob. Locking the first and second arms 12, 14 in this position is also possible and preferred through use of a lock or lockbox whose shackle 2 is inserted through the exposed portion of the staple 30 (transition from
(36) The hinge 38 may be any type of hinge or other structure that provides for a rotational or pivotal connection of the slotted part 34 to the base part 36. As an example, the hinge 38 may be a non-removable hinge with two hinge parts (leaves), one of which is attached to the slotted part 34 and the other attached to the base part 36. The leaves may be permanently attachment, e.g., using screws that pass through apertures in each leaf, or may be incorporated or integrated into the design of the slotted part 34 and base part 36. The type and construction of the hinge 38 is not important the invention, only that the slotted part 34 is pivotable relative to the base part 36 via the hinge 38 (at least in this embodiment).
(37) With respect to the material of the first and second arms 12, 14 of the apparatus 10, they may be made of a variety of materials, such as metal, and covered by a material that prevents damage to the door. For example, a protective covering or coating made of rubber or plastic would prevent scratching of the door and door handle when the apparatus 10 is installed.
(38) Staple 30 may be secured to the bottom portion 28 in a variety of different ways, but regardless of which way, it is preferably secured thereto in a manner to prevent it from separating from the bottom portion 28, e.g., preferably permanently fixed to the bottom portion 28 of the second arm 14. It is possible to design the second arm 14 with an integral or incorporated staple 30.
(39) Instead of fixing the staple 30 to the bottom portion 28, it is possible to use a staple unit 30A that is movable relative to the second arm 14. For example, as shown in
(40) In

(44) Skirts 52 may be composed of a thin plate attached to the lateral and bottom sides of the slotted part 34 or a thin rim projecting rearward from the lateral and bottom edges of the rear-facing surface of the slotted part 34, or other comparable or functionally equivalent structure. One purpose of the skirts 52 is to form a U-shaped channel on the side of the slotted part 34 of the first arm 12 that faces the second arm 14 so that the second arm 14 is more easily retained in a pre-determined position against the first arm 12 when the first and second arms 12, 14 are in the closed state. Thus, skirts 52 generally represent means to aid in positioning of the slotted part 34 over the bottom portion 28.
(45) Skirts 52 do not have to extend over the entire lateral and bottom sides of the slotted part 34 but may extend over only a portion thereof. The skirts 52 may also be fragmented into different parts and are not required to be situated on both of the lateral sides and bottom sides, but rather may be positioned on whichever sides are desired.
(46) The first and second arms 12, 14 may be connected together to keep them together with in the first, open state. For example, the first and second arms 12, 14 may be connected together at an upper edge region to enable the arms 12, 14 to pivot about this upper edge region between the first and second states while in continual connection to one another. To this end, connecting means are provided on the apparatus 10 to connect the first and second arms 12, 14 together to enable them to be manually moved between the first and second states. The connecting means encompass structure that connects the first and second arms 12, 14, together to enable them to have two positions, one in which it is possible to place the apparatus 10 over the part of the door handle to be received in the aperture 16 formed by the connection of the first and second arms 12, 14 (which position is referred to as the open position), and another position in which the apparatus 10 is configured to enable the first and second arms 12, 14 to be engaged with and preferably locked to one another (which position is referred to as the closed position). These connecting means may be any known connecting mechanism that functions to selectively connect two parts together. The parts do not have to be connected when in the open position, e.g., via a hinge, but could be completely separate when in the open position (see
(47) As an exemplifying, non-limiting embodiment of the connecting means, a hinge 46 may be provided at an upper edge regions of the first and second arms 12, 14. When pivoted into the open state about hinge 46, it is possible to bring the apparatus 10 over the part of the door lever 6 to be received in the aperture 16 through the space between the first and second arms 12, 14 (
(48) Hinge 46 may be a non-removable hinge with two planar hinge parts, called leaves, each attached to an upper surface of a respective one of the first and second arms 12, 14. The leaves each have knuckles through which a pin passes and enables pivotal movement of the leaves relative to one another, and thus pivotal movement of the first and second arms 12, 14 relative to one another. Attachment of the leaves to the first and second arms 12, 14 may be a permanent attachment, e.g., using screws that pass through apertures in each leaf into and through the upper surfaces of the head portion 18, 24, or may be incorporated or integrated into the design of the head portions 18, 24 of the respective first and second arms 12, 14. A cross-sectional view of the head portions 18, 24 including the hinge 46 is shown in

(51)
(52) To enable the apparatus 10 be used with variable-sized door levers 6 or other types of door handles, various mechanisms are provided to adjust the size of the aperture 16, referred to herein as adjusting means for adjusting a size of the aperture 16 to improve the retention of the apparatus 10 on the door lever 6. These mechanisms are generally configured to reduce the size of the aperture 16 from a largest possible size determined by the construction of the apparatus 10.
(53)
(54) Adjustment of the position of the semi-circular plates 54 relative to the inner surfaces of the respective head portion 18, 24 is effected by tightening or loosening set screws 56 which results in the aperture 16 being larger or smaller depending on the direction of rotation of the set screws 56. Other known mechanisms to effect movement of a plate, to result in a change in the size of the aperture 16 in the invention, are also considered part of the invention.
(55) In another embodiment, a functionally comparable or equivalent mechanism is integrated into the apparatus 10 which when rotated, moves the semi-circular plates 54 in and out, which the end result also being a variation in the size of the aperture 16. Adjustment of the size of the aperture 16 may be effected before the apparatus 10 placed over the door lever 6 or while the apparatus 10 is around the door lever 6.
(56)
(57) In another embodiment, a functionally comparable or equivalent mechanism is integrated into the apparatus 10 or set screws 58 which when rotated, moves the set screws 58 in and out, which the end result also being a variation in the size of the aperture 16. Adjustment of the size of the aperture 16 via rotation of the set screws 58 may be effected before the apparatus 10 placed over the door lever 6 or while the apparatus 10 is around the door lever 6.
(58) In this embodiment, adjustment of the set screws 58 can reduce the overall size of aperture 16, i.e., the size of the head hole, and provide a more secure attachment of the apparatus 10 to the door lever 6.
(59)
(60) The inserts 60A, 60B, 60C can be easily inserted into the recesses 20, 26, and removed therefrom when desired. In contrast to the use of semi-circular plates and an adjustment mechanism as in the embodiment in
(61)
(62) The inventor contemplates combining any of the head portions 18, 24 of the first and second arms 12, 14 shown in
(63) It is possible to construct the apparatus 10 in various sizes, for example with various size apertures 16, various depths of the head portions 18, 24 (depth being the front to back distance), and various thickness of the head portions 18, 24 (thickness being the distance between the inner facing surface of the head portions 18, 24 that define the respective recess 20, 26 and the outer facing surfaces).
(64) Apparatus 10 can thus be constructed to fit most door hardware styles including but not limited to door handles that are in the form of a lever, ball, biscuit, and tulip door knob styles.
(65) There are numerous advantages of the invention. For example, in some embodiments, there are no loose components (aside from the embodiments of
(66) Moreover, a characteristic of the invention believed to be unique when used to secure a lockbox to a door handle, and in the lockbox assembly of the invention, is that the lockbox can be secured to the door handle without having any part of the lockbox surround or encompass the door handle. That is, the shackle of a conventional lockbox typically is around the door handle when the lockbox is secured to a door handle. However, using apparatus 10, since there is a head portion 18, 24 on each arm 12, 14 which cooperate to surround the door handle (or least a part thereof), and then the bottom portions 22, 28 of the arms 12, 14 are situated below the respective head portion 18, 24, the shackle of the lockbox is engaged with the bottom portions 22, 28 below the head portions 18, 24 and therefore below the door handle. For example, the shackle of the lockbox can be attached to the staple 30 that projects through the slot 32 in the first arm 12, i.e., the shackle is inserted through an opening defined by the staple 30 in front of the front surface of the bottom portion 22 of the first arm 12. The lockbox is therefore entirely below the door handle (as clearly seen in
(67) Modifications of the apparatus 10 described above are contemplated. In one modification, the apparatus 10 is integrated into a shackle of, for example, a lockbox. In this case, instead of needing two components, i.e., a lockbox and the apparatus 10, a single component or lockbox assembly is provided and can be manufactured and sold as an integrated unit.
(68) Another modification of the apparatus 10 involves the use of inserts that can be placed into the aperture 16 to change the shape and/or diameter of the aperture 16 and accommodate different shapes and diameters of door handles.
(69)
(70) In apparatus 100, there is a first elongate arm 112 and a second elongate arm 114 which are similar to first and second arms 12, 14, respectively, except that the first and second arms 112, 114 are configured to define two different-sized apertures 16A, 16B between them when in the closed state (see
(71) With multiple different-sized apertures, apparatus 100 can be installed around different-sized door levers, door handles, etc., with the specific sized aperture 16A, 16B being selected for use dependent on the size of the door lever 6, door handle, etc. A user can try to position the apparatus 100 by moving the first and second arms 112, 114 from the open state to the closed state such that aperture 16A is placed around the door lever 6 and if it is too small and the door lever 6 does not fit in aperture 16A, the user can position the apparatus by moving the first and second arms 112, 114 from the open state to the closed state such that aperture 16B is placed around the door lever 6. It is preferable to use the smallest size aperture possible to avoid the apparatus 100 being only loosely fit around the door lever 6 and thus possibly removable when the first and second arms 112, 114 are in the closed state
(72) The same manner in which aperture 16 can be formed by the first and second arms 12, 14 in different ways as discussed above is also applicable to the formation of apertures 16A and 16B. For example, the first arm 112 includes a head portion 118 at an upper region of the member that defines two recesses 120, 122 and an elongate bottom portion 124 below the head portion 118. The second arm 114 includes a head portion 126 at an upper region of the member that defines two recesses 128, 130 and an elongate bottom portion 132 below the head portion 126. The head portions 118, 126 constitute an upper portion of the apparatus 100 while the bottom portions 124, 132 constitute a lower portion of the apparatus 100. Bottom portion 132 supports the U-shaped staple 30.
(73) Each recess 120, 128 has the same generally semi-circular cross-section in the depth direction of the respective member but its shape can vary and is not limited to being semi-circular or even uniform in the depth direction of the first and second arms 112, 114. Recesses 120, 128 have a shape relative to one another to form the aperture 16A with a cylindrical form, but this cylindrical form is not a required feature and may vary for different embodiments.
(74) Each recess 122, 130 has the same generally semi-circular cross-section in the depth direction of the respective member but its shape can vary and is not limited to being semi-circular or even uniform in the depth direction of the first and second arms 112, 114. Recesses 122, 130 have a shape relative to one another to form the aperture 16B with a cylindrical form larger than the cylindrical form of aperture 16A, but this cylindrical form is not a required feature and may vary for different embodiments. Head portions 118, 126 are therefore provided with curved forms are shown.
(75) The bottom portion 124 of the first arm 112 has an upper end region integral with the head portion 118, but may alternatively be connected thereto if formed from separate members. This upper end region is formed primarily by a hinge part 168 described below. The bottom portion 124 also includes slotted part 34 with the slot 32 as described above. The bottom portion 132 of the second arm 114 has an upper end region integral with the head portion 126, but may alternatively be connected thereto if formed from separate members. The slot staple 30 extends forward of a front surface of the bottom portion 132.
(76) For this embodiment, structure to adjust the size of the aperture is not required, although not precluded, since the apparatus 100 provides two different-sized apertures 16A, 16B and the sizes of these apertures 16A, 16B can be selected in view of the size of common door levers, door handles etc., to enable apparatus 100 to be capable of use with most if not all such door levers, door handles and the like. Use of mechanisms disclosed above, see, e.g.,
(77) The first arm 112 has an intermediate region 134 between the recesses 120, 122 while the second arm 114 has an intermediate region 136 between the recesses 128, 130 which contacts intermediate region 134 when the first and second arms 112, 114 are in the closed state (see
(78) The structure that maintains the first and second arms 112, 114 in the second, closed state and prevents their movement from the second, closed state to the first, open state has various forms, and may be the same as for apparatus 10, e.g., the engagement means including the staple 30 on the second arm 114 and cooperating slotted part 34 on the first arm 112.
(79) Another difference between apparatus 100 and other embodiments of the apparatus 10 relates to hinge 138 in apparatus 100 above the apertures 16A, 16B. Hinge 138 has an E-shaped first hinge part 140 on, e.g., formed integral with, the first arm 112 and a C-shaped second hinge part 142 on, e.g., formed integral with, the second arm 114 intermeshed with hinge part 140. A hinge pin 144 extends parallel to the axes of the apertures 16A, 16B, and has its ends secured on hinge part 140 and passes through apertures in hinge part 142 and the central leg of hinge part 140 (see
(80) Yet another difference is the construction of a hinge 38A to connect the slotted part 34 to the base part 36. In this embodiment, the base part 36 of the bottom portion 124 comprises an E-shaped part 168 adjacent the head portion 118, while the slotted part 34 comprises two extensions 170 formed thereon, e.g., integral therewith or as part thereof. A hinge pin 172 passes through the E-shaped part 168 and extensions 170 to enable pivotal movement of the slotted part 34 relative to the base part 36 and thus to the head portion 118 (see
(81) Optional rubber covers 112A and 114A may be provided for the first and second arms 112, 114. These rubber covers 112A, 114A are a surface covering for the typically metal material of the first and second arms 112, 114 and do not affect the formation of the apertures 16A, 16B or recesses or any other structure of the first and second arms 112, 114 that is to be covered by the rubber covers 112A, 114A, respectively, As such, the rubber covers 112A, 114A may be considered part of the first and second arms, 112, 114 respectively.
(82) As described above, the apparatus 10, 100 generally are used to secure a lock or lockbox to a door handle and especially a door lever used as a door handle. However, this described use of the apparatus 10, 100 is not intended to limit the invention and other uses are possible and should be considered within the scope and spirit of the invention.

(84) To engage with key box 146, apparatus 148 includes a first arm 150 and a second arm 152 which are similar to first and second arms 112, 114, respectively, except that bottom portions 154, 156 of the first and second arms 150, 152 each include an elongate shackle prong 158, 160 extending downward in a direction away from the head portions 118, 126. The shackle prongs 158, 160 are spaced apart the same distance as complementary receptacles 162, 164 in the key box 146 to enable them to easily insert into the receptacles 162, 164 and lock into the key box 146. Shackle prongs 158, 160 are generally parallel to one another and may have the same axial length. A notch is provided in each shackle prong 158, 160 in a manner known to those skilled in the art to which this invention pertains.
(85) The shackle prongs 158, 160 are releasable from the key box 146 when a shackle code is received by electronic circuitry in the key box 146 (or alternatively depending on the construction of the key box 146, a shackle code is manually entered into a code-receiving component in the key box 146). The manner in which the shackle code is entered, received and processed by the key box 146 is not critical to the invention and all that is required is that upon entry of a correct shackle code, both shackle prongs 158, 160 are removable from engagement with the key box 146. The shackle prongs 158, 160 are engaged with the key box 146 by lining up the shackle prongs 158, 160 with the receptacles 162, 164 in the key box 146 and pushing the shackle prongs 158, 160 down into the key box 146 until they click.
(86) A different code is used to access the key compartment in the key box 146, and manner in which the key access code is entered, received and processed by the key box 146 is not critical to the invention. The mechanism to receive the shackle code and key code either manually or electronically is represented schematically as 174.
(87) Elongate shackle prongs may be included on the first and second arms 12, 14 of apparatus 10 instead of the engagement means disclosed above. As such, the bottom portions 22, 28 of the first and second arms 12, 14 may each be provided with an elongate shackle prong extending downward in a direction away from the head portions 18, 24 and used with the key box 146. Such shackle prongs would be similar to shackle prongs 158, 160 and an apparatus in accordance with the invention would therefore include first and second arms having head portions like the head portions 18, 24 of any of the first and second arms 12, 14 disclosed herein, shackle prongs on or as the bottom portions, and a key box. Among other things, a separate lock engaged with a staple is not required for such an apparatus.
(88) Shackle prongs 158, 160 are part of an engagement structure that enables engagement of the key box 146 to the arm sub-assembly 166. This engagement structure may be any structure that enables two prongs, one from each of the arms, to engage with and be lockable to structure in or on the key box 146. As shown, this structure is the formation of elongate members as prongs with notches that engage with complementary structure inside the key box 146. Other structure is also possible including structure of the elongate members that engages outside of the key box, structure of the elongate members that engage with each other and then with structure in or on the key box 146, and structure of the elongate members that engage with a common structure in or on the key box. All such structure is encompassed with the term engagement structure or engagement means, the basic functionality of this structure or means being to provide a connection between both of the arms and a common key box while preventing separation of the arms while the engagement structure is engaged with and locked into the key box.
(89) Accordingly, an embodiment of the invention is possible wherein the first and second arms each include an engagement structure that cooperates with mating engagement structure on a lock, lock box or key box so that when the first and second arms are in a closed state, it is possible to engage the lock, lock box or key box with the engagement structure and lock the first and second arms in a closed position around a door knob, door lever, door handle and the like. Only unlocking of the lock, lock box or key box enables disengagement of the engagement structure on the first and second arms from the lock, lock box or key box and then opening of the first and second arms to enable release of the first and second arms from the door knob, door lever, door handle and the like (for repositioning of the apparatus). When installed on a door knob, door lever, door handle or the like with a lock box or key box, a realtor can manually or electronically enter a code to access a key or other access device in a compartment in the lock box or key box and enter a premises for a showing.
(90) While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and, therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
