BACKGROUND
Outdoor activities typically require the use of a device such as a walking stick, umbrella or other mechanism. However, in certain circumstances, the user also needs to carry a backpack or other means of carrying other equipment during such outdoor activity. In some cases, the extra equipment required to participate in some outdoor activities is minimal but yet still requires the user to carry a backpack or other large carrying device to carry the extra equipment. Unfortunately, the backpack adds bulk and weight to the user. Moreover, extra equipment may also be strapped to the user with straps, brackets and other attachment mechanism but these non-backpack solutions also add bulk to the user when participating in certain outdoor activities.
Accordingly, there is a need in the art for an improved method and device for carrying extra equipment while participating in an outdoor activity.
BRIEF SUMMARY
The various embodiments described herein is related to a quick disconnect storage compartments that can be incorporated into handheld devices such as umbrellas, walking sticks, bicycle handlebars, etc.
The quick disconnect storage compartment utilizes an interior cavity of the handle of the handheld device to store an object including but not limited to a tool, knife, pepper spray and other objects that are described herein. The interior cavity is accessible through an opening at a distal end of the handle. Moreover, the interior cavity may be covered with an end cap or cover that is removably attachable to the distal end of the handle to prohibit access to the interior cavity. The object may be attached or secured to the endcap or cover so that removal of the end cap or cover also removes the object from the handle. The latching mechanism used to secure the endcap or cover to the handle may be operated by depressing two buttons on opposite sides so that opposed forces must be applied to the two buttons to release the endcap or cover from the handle. In this matter if and when the handle contacts an object or ground, the end cap cover does not inadvertently become dislodged from the handle. The buttons may be incorporated into the endcap or the handle. In operation, the user grips the endcap or cover, and thus the buttons with one hand and the handle with the other hand. By utilizing the interior cavity of the handle to store an object, the object is concealed from others. If the object is a weapon such as a knife, then carrying the knife is not threatening to others yet the user is able to quickly deploy the weapon for self-defense.
More particularly, a method for deploying an object hidden within a handle of a handheld device is disclosed. The method may comprise the steps of gripping a handle with a first hand of a user; gripping an end cap with a second hand of the user; applying oppositely directed forces on first and second buttons formed on either the handle or the cap; disengaging first and second latches formed on the first and second buttons from first and second catches formed on the handle or cap; and pulling the cap with the second hand of the user to remove the object from the handle.
In the method, the applying step may include the step of applying oppositely directed forces 180 degrees apart from each other.

DETAILED DESCRIPTION
Referring now to the drawings, an object 10 which is concealed carried within a handle 12 is shown. The tool 10 may be a pepper spray 14, a tool 16, a tube 18 for carrying things, a knife 20, a battery 22 for powering a battery-operated device 24 (e.g. light 24a or speaker 24b). The object 10 may be disposed within the cavity 26 defined by the handle 12 and removably secured therein. To remove the object 10 from the cavity 26, the user may grip the handle 12 with a first hand and pull an end cap 28 off of the handle 12 with a second hand. A latching mechanism may be incorporated into the handle or the end cap 28. The latching mechanism may be operated by either the first or second hand. The latching mechanism may require opposing clamping forces in order to remove the end cap 28 from the handle 12. This feature mitigates inadvertent dislodging of the object 10 from the cavity 26 in the event that the handle contacts a table, ground or other hard object. Symmetrical or asymmetrical opposed forces are required to disengage the latching mechanism. Dropping the device would produce a uni-directional force that might actuate one of two buttons of the latching mechanism but not both.
Referring now to FIG. 1, a portion of a bicycle handlebar 30 is shown. The bicycle handlebar 30 is hollow, defining the cavity 26 that may extend end to end throughout the tube of the handlebar 30. A grip 32 is disposable over an end portion of the handlebar 30 and securable to the end portion of the handlebar 30 by way of collars 34, 36. The grip 32 has a gripping portion 38. On opposed sides of the gripping portion 38, flanges 40 extend past the gripping portion 38. An inner diameter 42 of the flanges 40 is equal to or few thousands of an inch larger than an outer diameter 44 of the handlebar 30. The flanges 40 may preferably be fabricated from a plastic material that is rigid but yet slightly deformable so that the collars 34, 36 can squeeze the flanges 40 into frictional engagement with the exterior surface of the tube of the handlebar 30. The proximal collar 34 may have a circular outer circumference and a grooved inner circumference that receives the flanges 40. In particular, the inner circumference of the collars 34, 36 may have two grooves 46. The two grooves 46 receive the flanges 40 and the interior surfaces of the grooves 46 contact the exterior surfaces of the flanges 40. Moreover, an inner radius 48 of the collars 34, 36 may be equal to or slightly greater than an outer radius 15 of the handlebar 30 so that the interior surface defined by the inner radius 48 can contact the exterior surfaces of the handlebar 30. The collars 34, 36 may be made narrower or compressed by way of bolt 52. To secure the grip 12 onto the end portion of the handlebar 30, the grip 12 is placed over the handlebar, as shown in FIG. 2. The collar 34 is loosened and placed over the flanges 40 at the proximal side of the grip 12. Once the flanges 40 are disposed over the handlebar 30, the collar 34 is tightened by engaging the bolt 52. By tightening the bolt 52, the collar 34 compresses the flanges 40 onto the handlebar 30. The collar 36 is also placed over the flanges 40 in the handlebar 30 and its bolt 52 is tightened to further secure the collar 34 and the flanges 40 to the handlebar 30. The collar 36 has the same configuration as that of collar 34 except that collar 36 has a distal lip 54.
The distal lip 54 is part of the latching mechanism that allows the end cap 28 to be removably attachable to the handlebar 30. In particular, the end cap 28 has tabs 56, 58 that are traversable between an engaged position and a disengaged position. In the engaged position, the tabs 56, 58 are biased outward and catches the lip 54. In the disengaged position, the tabs 56, 58 are pushed inward by a person's fingers and releases the lip 54.
Referring now to FIG. 5, the pepper spray 14 is shown exploded off of the end cap assembly 28. The end cap assembly 28 includes the tabs 56, 58. The tabs 56, 58 are attached to buttons 60, 62. The tabs 56, 58 are preferably integrally formed with the buttons 60, 62 in that they 56, 60 and 58, 62 may be injection molded as a single piece. The end cap 28 additionally has a disc shaped body 64. The body 64 may have slots 66, 68 on opposed sides that receive the buttons 60, 62. In particular, the buttons 60, 62 have tongues 70, 72 that are slidably received into the slots 66, 68. The buttons 60, 62 can slide within the slots 66, 68 between the two positions, namely, the disengaged position and the engaged position. The end cap assembly 28 also has springs 74 which bias the buttons 60, 62 to the engaged position. The springs 74 are retained and positioned on post 76 formed integrally with the body 64. The post 76 extends away from each other as shown in FIG. 5. An outer diameter of the post 76 is smaller than an inner diameter of the spring 74 so that the spring 74 can freely be compressed onto the post 76. The buttons 60, 62 may each have a receiving hole 78 that receives the spring 78. The springs 74 are trapped between the post 76 and the hole 78.
When the buttons 60, 62 are depressed to the disengaged position and released, the springs 74 push the buttons 60, 62 back out to the engaged position. To hold the position of the buttons 60, 62 in the engaged position as shown in FIG. 6, the body has inwardly directed pairs of feet 80 which hold each of the buttons 60, 62 in place when the person releases the buttons 60, 62. The buttons have outwardly directed fingers 82 that catch the inwardly directed feet 80. In this way, the buttons 60, 62 do not pop out of the slots 66, 68. The exterior surfaces of the buttons 60, 62 may have a curved configuration together with the exterior circumference of the body 64 that forms a circular configuration when the buttons 60, 62 are in the engaged position.
As discussed above, the buttons 60, 62 and likewise the tabs 56, 58 may be traversed between engaged and disengaged positions. In the engaged position, the tabs 56, 58 interfere or contact the lip 54 in the distal collar 36 (see FIG. 4). In the disengaged position, the tabs 56, 58 do not interfere or contact the lip 54 in the distal collar 36 because the tabs 56, 58 are displaced closer to each other in the disengaged position compared to the engaged position.
Referring now to FIGS. 6 and 7, the tabs are shown in the engaged position and the disengaged position respectively. In the engaged position, the tabs 56, 58 define a distance 84. The distance 84 is measured from the widest part of the tab 56, 58 when the buttons 60, 62 are in the engaged position. In the disengaged position, the tabs 56, 58, as shown in FIG. 7, define a distance 86. The distance 86 is less than or equal to the inner diameter 88 of the lip 54, whereas, the distance 84 is greater than or equal to the inner diameter 88 of the lip 54. In this way, the end cap 28 is removably attached to the collar 36 by depressing the buttons 60, 62 or releasing them. A radius of the outer periphery of the tabs 56, 58 may be smaller than a radius of an inner periphery of the lip 54 so that the tabs 56, 58 may clear the lip 54 when the tabs are traversed to the disengaged position.
The body 64 also has prongs 90, 92 which can deflect inward but resiliently deflect back outward to its normal position shown in FIGS. 6 and 7. The object 10 may be secured to the body 64 with the prongs 90, 92. By way of example and not limitation, the object 14 may be held within a tubular member 94. The tubular member 94 may have apertures 96 that receive ridged extensions 98. The outer diameter 100 of the ridged extensions 98 is greater than an inner diameter 102 while an outer diameter of the prongs 90, 92 at its base is slightly smaller than the inner diameter 102 of the tubular member 94. A leading edge of the prongs 90, 92 may be significantly smaller than the inner diameter 102 of the tubular member 94 to help the user insert the prongs 90, 92 into the tubular member 94. The leading edge portion of the prongs 90, 92 above the ridged extensions 98 is preferably beveled to help deflect the prongs 90, 92 inward.
Referring now to FIGS. 8-13, the object 10 may be any one of a plurality of different types of objects. For example, as shown in FIGS. 8 and 9 and discussed above, the object 10 may be a pepper spray 14 which is embedded within a tubular member 94. The object 10 may also be a tool 16. The object 14 may also be a storage container 18 as shown in FIG. 10. The object may also be a knife 20, as shown in FIG. 11. As shown in FIGS. 12 and 13, the object 10 may be a battery 22 which may be contained within a tubular member 94 for powering a light 24a or speaker system 24b. Regardless of the object 10 being hidden within the handle 12, the object 10 may be quickly detached and removed from the handle by depressing the buttons 60, 62. Moreover, the buttons 60, 62 which are on opposite sides of the end cap 28 prevent the object 10 from inadvertently being dislodged from the handle 12 if the handle 12 was to fall down and accidently hit the ground or table or some other hard object that might depress one of the buttons 60, 62 but would not depress both 60, 62 simultaneously to detach the end cap assembly 28 from the handle 12.
Referring now to FIG. 14, it is also contemplated that the buttons 60, 62 may be placed in various angular orientations. In FIGS. 6 and 7, the buttons 60, 62 are 180° opposite of each other. However, other angular orientations are also contemplated. By way of example and not limitation, the angular orientation of the buttons 60, 62 may be 135°, 90° or 45°. Simply put, the buttons 60, 62 may be placed in any angular orientation with respect to each other between 45° and 180°.
Additionally, the tool 10 being inserted into the handle 12 for storage may extend past a length of the handle into the tube 30. Additionally, if the object 10 is flexible, then the object 10 can be inserted into the handle 12 and into the tube 34 as required.
Referring now to FIGS. 15-18, the handle 120 may be attached a device 122 (e.g. umbrella) in a different manner compared to that shown and described in FIGS. 1-7. In particular, the handle 120 may be an injection molded piece wherein its proximal end portion 124 is screwed on to a tubular member 126 with a screw 128 and/or glued/adhered.
The handle 120 may be an injection molded plastic piece that has an exterior surface contoured to provide grip for a user. The handle 120 is fabricated to have an interior cavity 130 in which the object 10 may be stored when concealed. A distal end portion 132 may have opposed lips 134 formed therein which catch the tabs 56, 58 of the end cap assembly 28 to retain the tool or object 10 within the handle 120 when the tabs 56, 58 are in the engaged position. The tabs 56, 58 operate in the same manner as discussed above in relation to FIGS. 1-8 in that the distance 84 between the tabs 56, 58 is greater than an inner diameter 136 of the distal end portion 132 of the handle 120, whereas, the distance 86 of the tabs 56, 58 is less than the inner diameter 136 of the distal end portion 132 of the handle 120.
The lips 134 may be covered by a ring 138 which can be adhered, press fitted, or somehow attached to the distal end portion 132 of the handle 120 to cover/hide 56, 58, 134.
Referring now to FIG. 19, a variant of the first and second embodiments of the quick disconnect storage compartment is disclosed. In the first and second embodiments of the quick disconnect storage compartment, the buttons 60 were incorporated into the endcap 28. However, it is also contemplated that the buttons 60a may be incorporated into the handle 12a or the distal collar 36a. The buttons 60a have tabs that engage the lips 54a, 134a. The buttons 60a and tabs 56a, 58a are biased to the engaged position with springs 74a. The springs 74a are disposed on opposed sides of a shaft that connects the buttons 60a to the tabs 56a, 58a to balance the buttons 60a while it is being traversed between engaged and disengaged positions. The buttons 60a are retained within a cavity 150 formed in the handle 12a or distal collar 36a. The engaged position shown in FIG. 19, the lips 54a, 134a are trapped under the tabs 56a, 58a. To remove the object from the handle, the buttons 60a are depressed to traverse the tabs 56a, 58a from the engaged position to the disengaged position. In the disengaged position, the lips 54a, 134a are not trapped under the tabs 56a, 58a. Rather, the lips 54a, 134a may be lifted up in order to remove the object from the handle. In this manner, when the user removes the object from the handle, the user grips the buttons with one hand while securely removing the object with the other hand. This allows for greater retention of the object since the same hand is not both operating the button and gripping the object.
The above description is given by way of example, and not limitation. Given the above disclosure, one skilled in the art could devise variations that are within the scope and spirit of the invention disclosed herein, including various ways of securing the handle to a tube. Further, the various features of the embodiments disclosed herein can be used alone, or in varying combinations with each other and are not intended to be limited to the specific combination described herein. Thus, the scope of the claims is not to be limited by the illustrated embodiments.
