DETAILED DESCRIPTION OF THE INVENTION

(11) Referring to the accompanying drawings wherein like reference numbers refer to the same or similar elements, FIGS. 1-5 show an apparatus 10 in accordance with the invention which generally, and in a preferred use, secures a lockbox 4 to a door lever 6 of a door 8. The apparatus 10 includes two members, which will be referred to as a first arm 12 and a second arm 14, that have a cooperating first, open state in which the first and second arms 12, 14 are at least partly separated from one another (FIGS. 1 and 2) and a cooperating second, closed state in which an aperture 16 is defined between them (FIGS. 3-5). In the open state, the first and second arms 12, 14 are positionable around the door lever 6 or removable from such a position (FIG. 2). (Identification of a preferred use of the apparatus 10 with a lock box 4 and door lever 6 is not intended to limit the invention in any manner whatsoever.) The arms 12, 14 may be considered to be structure that has a body and is generally elongate.

(12) 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 (FIGS. 3-5). The mechanism that effects the locking of the first and second arms 12, 14 in the second state may be any type of conventional lock or lockbox and is not a required part of the invention. However, a lockbox assembly in accordance with the invention includes apparatus 10 and any type of lockbox 4.

(13) When the lockbox 4 is secured to the apparatus 10 as shown in FIG. 5 (in a manner described below), the shackle 2 of the lockbox 4 is secured to the apparatus 10 which in turn is secured to the door lever 6, which is being used herein as an example of a door handle. The apparatus 10 would therefore maintain the lockbox 4 in a secured position on the door lever 6. The lockbox 4 would not be able to be removed while the apparatus 10 is in place and the shackle 2 of the lockbox 4 is secured to the apparatus 10. Realtors could thus insert a key to one of their listings into the lockbox 4 and using the apparatus 10, place the lockbox 4 onto the door lever 6 of the door 8 of this listing. Thereafter, to enable other realtors to show the listed property, they would be able to provide only the code to the lockbox 4 to enable the other realtors to access the key inside and use the key to access the listed property. Apparatus 10 prevents disengagement of the lockbox 4 for the door lever 6, and addresses the drawbacks of the prior art devices discussed above. Use of the apparatus 10 with electronic lockboxes is also possible.

(14) 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 FIGS. 1-5, the first arm 12 includes a head portion 18 at an upper region of the member that defines a recess 20 and an elongate bottom portion 22 below the head portion 18. The second arm 14 includes a head portion 24 at an upper region of the member that defines a recess 26 and an elongate bottom portion 28 below the head portion 24. The head portions 18, 24 constitute an upper portion of the apparatus 10 while the bottom portions 22, 28 constitute a lower portion of the apparatus 10.

(15) 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.

(16) 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.

(17) 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 (FIGS. 3 and 4) to the first, open state (FIGS. 1 and 2) has various forms. The purpose of such structure is, when the first and second arms 12, 14 are around a door handle, to maintain the first and second arms 12, 14 around the door handle, whether a door lever or otherwise. This structure will generally be referred to as engagement means for engaging with the first and second arms 12, 14 and maintaining the first and second arms 12, 14 in the second, closed state and preventing movement of the first and second arms 12, 14 from the second, closed state to the first, open state. Thus, when the first and second arms 12, 14 are around a door handle, the engagement means maintain the first and second arms 12, 14 around the door handle. The engagement means do not necessarily include a locking structure, or other structure, that locks the first and second arms 12, 14 in the closed state.

(18) 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.

(19) 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.

(20) The staple 30 generally may also be considered a support for a lockbox and more specifically a support for a shackle of a lockbox.

(21) 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 (FIG. 1). Staple 30 extends in a direction from the bottom portion 28 of the second arm 14 to enable it to pass through and extend beyond the slot 32 of the first arm 12, when the first and second arms 12, 14 are in their closed state. The extent to which the staple 30 extends beyond the slot 32 forward of the front surface of the bottom portion 22 is determined to allow a lock or more likely the shackle of a lockbox, to pass through the staple 30 and be secured around the staple 30 (FIG. 5).

(22) 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 (FIG. 1). Slotted part 34 is slotted in the sense that it includes the slot 32. The slotted part 34 may be considered similar to a hasp, but is not required to be made from metal.

(23) 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 (FIG. 2), lifting the slotted part 34 upward to allow the first and second arms 12, 14 to be able to be positioned alongside one another (FIG. 3). Such a position is prevented in the open state when the slotted part 34 abuts against the staple 30 (FIG. 2). By lifting the slotted part 34 upward, the base part 36 can be moved alongside the bottom portion 28 of the second arm 14 and then the slotted part 34 can be lowered when the slot 32 aligns with the staple 30 (transition from FIG. 3 to FIG. 4). The bottom portions 22, 28 are thus alongside one another when the first and second arms 12, 14 are in the closed state.

(24) 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 FIG. 4 to FIG. 5).

(25) 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).

(26) 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.

(27) 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.

(28) 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 FIG. 6, instead of fixing the staple 30 to the bottom portion 28 as in FIG. 1, the staple unit 30A is pivotally attached to the bottom portion 28, e.g., at its lower edge region. As pivotal attachment means, a hinge 40 may be used to pivotally attach an optional backplate 42 connected to the staple 30 (thereby forming the staple unit 30A) to the bottom portion 28. Hinge 40 is configured and positioned relative to a slot 44 in the bottom portion 28 to enable the staple 30 to pivot into the slot 44 and also into the slot 32 in the slotted part 34 of the first arm 12 when the slot 32 aligns with the slot 44 such that the staple 30 extends sufficiently beyond the slot 32 to allow, for example, the shackle of a lockbox to pass through the staple 30 and be secured around the staple 30.

(29) In FIG. 7, the staple unit 30A, including its optional backplate 42, is not attached at all to the bottom portion 28, but rather is a free, loose component. Staple unit 30A is dimensioned such that, when inserted through the slots 32, 44, the staple 30 thereof extends sufficiently beyond the slot 32 to allow the shackle of a lockbox to pass through the staple 30 and be secured around the staple 30.

(30) Although the embodiments in FIGS. 1-5 include a hinged first arm 12, it is also possible to construct the apparatus 10 without a hinged first arm, which first arm lacking a hinge is designated 12A in FIG. 8. First arm 12A is an elongate piece of material, e.g., metal with a protective coating or covering as mentioned above, and includes the slot 32, but not the hinge 38. Similar to FIG. 6, staple unit 30A is pivotally attached to the bottom portion 28, e.g., at its lower edge region, and as pivotal attachment means, hinge 40 is used to pivotally attach the optional backplate 42 to the bottom portion 28. The staple unit 30A is pivoted in the direction of arrow A into the slot 44 and aligning slot 32.

(31) In FIG. 9, the staple unit 30A is not required to be attached to any part of the second arm 14, but rather can be a free, loose component (like in FIG. 7). A loose component is one which is not always connected to remaining parts of the apparatus 10. Staple unit 30A is dimensioned such that, when inserted through the slots 32, 44, the staple 30 thereof extends sufficiently beyond the slot 32 to allow the shackle of a lockbox to pass through the staple 30 and be secured around the staple 30. In this embodiment, both arms 12A, 14 lack a hinge component. As such, they may be rigid elongate members.

(32) FIGS. 10 and 11 show use of skirts 52 situated on the lateral and bottom sides of the slotted part 34 that are configured to extend over the lateral and bottom sides of the bottom portion 28 when the first and second arms 12, 14 are in the closed state (see FIG. 11). These skirts 52 may be formed from the same material as the material of the slotted part 34, e.g., integral therewith, or from a separate and/or different material that is attached to the lateral and rear sides of the slotted part 34. Skirts 52 aid in positioning of the slotted part 34 over the bottom portion 28 because they define a three-sided receptacle into which the bottom portion 28 can be easily inserted as the slotted part 34 is pivoted over the staple 30.

(33) 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.

(34) 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.

(35) 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 FIG. 12).

(36) 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 (FIG. 2). The first and second arms 12, 14 are then pivoted into the closed state about hinge 46 to cause the part of the door lever 6 to be received in aperture 16 which is formed upon moving the first and second arms 12, 14 to their closed state. In the closed state, the first arm 12 is situated on the left side of the door lever 6 with the recess 20 alongside the part of the door lever 6 received in aperture 16 and the second arm 14 is situated on the right side of the door lever 6 with the recess 26 alongside the part of the door lever 6 received in aperture 16.

(37) 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 FIG. 12.

(38) FIG. 13 shows an alternative hinge 46A wherein the leaves are embedded into the head portions 18, 24 and not alongside the upper surface.

(39) FIG. 14 shows connecting means that do not comprise a hinge, namely, wherein the connecting means comprise pins 48 on each head portion 18, 24 and which pins 48 cooperate with one another to provide a closed and secure state of the first and second arms 12, 14 (only the head portions 18, 24 of which are shown, with the bottom portions 22, 28 being any of the bottom portions disclosed herein). The pins 48 are removably attached to one another and can be forcibly separated from one another when installing and removing the apparatus 10. By suitable design of the dimensions of the apparatus 10, the pins 48 cannot be separated from one another to enable removal of the apparatus from the door lever 6 to which the apparatus 10 is attached when a lock or lockbox shackle is present in the staple 30.

(40) FIG. 15 is a top view of another connecting means wherein the first and second arms 12, 14 are provided with an integrated hinge 50 formed by structure of the head portions 18, 24 themselves. The integrated hinge 50 can be replaced by any other structure that forms an integrated pivot structure, which structures are known to or readily ascertainable by those skilled in the art, and are considered to be encompassed by the invention.

(41) 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.

(42) FIG. 16 shows the presence of a generally semi-circular plate 54 inward of each inner surface of the head portions 18, 24. The semi-circular plates 54 occupy a small portion of each recess 20, 26 defined by the head portions 18, 24, i.e., are situated on opposite sides of the aperture 16. The semi-circular plates 54 are configured and dimensioned to avoid interfering with one another when the apparatus 10 is in the closed state.

(43) 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.

(44) 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.

(45) FIG. 17 shows another adjusting mechanism or means for adjusting the size of the aperture 16. In this embodiment, a respective rotatable set screw 58 is installed in each head portion 18, 24 and has an edge 60 projecting into the recess 20, 26 a distance that varies as a function of the rotation of the set screw 58. The set screws 58 are thus on opposite sides of the aperture 16, but not necessarily opposite one another. The user, when seeking to reduce the size of the aperture 16 from a larger, possibly initial setting, can place a screwdriver or other tool or instrument in a slot of the set screw 58 and rotate it until the edge 60 is positioned close to or against the door lever 6. The apparatus 10 would then be secured to the door lever 6.

(46) 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.

(47) 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.

(48) FIG. 18 shows yet another adjusting mechanism or means to adjust the size of the aperture 16 in order to provide a more secure attachment of the apparatus 10 to, for example, the door lever 6. Specifically, it is possible to provide variable-sized head hole inserts 60A, 60B, 60C that are inserted into the aperture 16, one into each recess 20, 26, and change the diameter of the aperture 16 when present therein. Inserts 60A, 60B, 60C may have a semi-circular cross-section, i.e., are semi-cylindrical, and the inserts of each pair are substantially identical. The specific one of the pairs of inserts 60A, 60B, 60C to use for each door handle is user-selectable and positionable around the door lever 6 depending on the diameter of the portion of the door lever 6 around which the apparatus 10 is to be positioned.

(49) 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 FIG. 16, in this embodiment the inserts 60A, 60B, 60C may be loosely inserted into the recesses 20, 26 and secured in place around the door lever 6 when the first and second arms 12, 14 are moved into the closed state.

(50) FIG. 19 illustrates a mechanism to improve the attachment of the head portions 18, 24 together. The surfaces of the head portions 18, 24 facing one another are provided with complementary mating structures, for example, a pin 62 and a pin hole 64. By inserting the pin 62 in the pin hole 64 upon closure of the first and second arms 12, 14, the head portions 18, 24 becomes less susceptible to being forced or pried open. The pin 62 and pin hole 64 represent means for releasably securing the head portions 18, 24 together when the apparatus 10 is in the closed state. Other known structures that provide this functionality are considered to be part of the invention, and one skilled in the art would understand how to incorporate them into the invention based on the disclosure herein.

(51) The inventor contemplates combining any of the head portions 18, 24 of the first and second arms 12, 14 shown in FIGS. 12-19 with any of the bottom portions 22, 28 shown in FIGS. 6-11. As such, a large number of variations of the apparatus 10 are possible and considered within the scope of the invention. Moreover, the complementary mating structure shown in FIG. 19 may be used with and integrated into any of the other head portions disclosed herein.

(52) 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).

(53) 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.

(54) There are numerous advantages of the invention. For example, in some embodiments, there are no loose components (aside from the embodiments of FIGS. 7 and 9). The staple 30 is attached to the second arm 14 and the first and second arms 12, 14 are attached to one another. A single, unitary assembly is thus formed which prevents loss of any particular piece and aids in maintaining the functionality of the apparatus 10.

(55) 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 FIG. 5). This is very advantageous since the lockbox, when secured to the apparatus 10 in turn secured to the door handle, should not interfere with the movement of the door handle to open or close the door.

(56) 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.

(57) 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.

(58) As described above, the apparatus 10 generally is used to secure a lockbox to a door handle and especially a door lever used as a door handle. However, this described use of the apparatus 10 is not intended to limit the invention and other uses are possible and should be considered within the scope and spirit of the invention.

(59) 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.
