Description: SMOKING ASSEMBLY Cross Reference This patent application claims the benefit of priority of, and is a continuation-in-part of, co-pending U.S. patent application Serial No. 08/876,911 filed on June 17, 1997. Technical Field The present invention relates to a smoking assembly adapted to store smoking material. Background Art Smoking assemblies adapted to hold a smoking pipe and smoking material are heretofore known. U.S. Patent No. 4,214,658 to Crow, for example, discloses a smoking system comprising a smoking pipe and housing that defines two cavities, one of which is shaped to receive the smoking pipe and the other of which is shaped to store smoking material. The Crow system also includes a top cover slidably mounted on the receptable and adapted to cover the first and second cavities. The smoking pipe can be stored and also can be removed and packed with smoking material quickly and easily for smoking. The Crow assembly does not, however, provide a complete smoking assembly because it does not include a lighter for igniting the smoking material for smoking. Accordingly, it is an object of the present invention to provide a complete smoking assembly that includes a lighter for igniting smoking material stored by the assembly. It is a further object of the present invention to provide such a complete smoking assembly that is neat and compact, easy to use, and easy to store and transport. Disclosure Of Invention In accordance with these and other objects, a smoking assembly is provided that includes a housing defining a chamber for storing smoking material and an aperture, a first or top cover associated with the housing, and a lighter contained substantially within the housing for emitting a flame through the aperture to ignite outside the housing a portion of the smoking material removed from the housing. The first chamber defined by the housing has an open end and the top cover is adapted to open and close the open end of the first chamber. Desirably, the lighter is received substantially within a second chamber defined by the housing and the aperture is defined on a side of the housing. The lighter is positioned such that it can be activated adjacent one end of the housing, and includes a valve stem positioned adjacent the aperture defined by the housing so that flame emitted by the lighter can pass from the valve stem through the aperture. The lighter also includes an igniter that desirably extends substantially perpendicular to the valve stem. The smoking assembly also includes a smoking pipe for removing and receiving the portion of the smoking material from the first chamber, and the housing further defines an elongated channel that removably receives the smoking pipe. The channel defined by the housing also has an open end, which also may be opened and closed by the top cover. After removing the portion of the smoking material from the housing, the smoking pipe is used to hold the portion of the smoking material so that it can be ignited by the lighter for smoking. The lighter may have any suitable construction and is joined to the housing in any suitable manner. In accordance with a preferred embodiment, however, the lighter is configured and joined to the housing in a manner such that the housing can be manually held and the lighter manually activated at one time by the same hand. Desirably, the housing includes an inner wall that defines a continuous passage extending through the housing that includes the first and second chambers. The first and second chambers may be separated by one of the ends of the lighter or by a spacer or the like. The housing desirably is constructed of any suitable material, such as, for example, aluminum or other metal. The present invention in accordance with a preferred embodiment provides a complete and compact smoking assembly for storing and smoking material. The housing stores the smoking material and contains the lighter and smoking pipe in a neat and compact manner such that the smoking assembly is easy to store and transport. Additionally, the lighter has a compact configuration and is contained substantially within the housing in a manner such that it is easy and convenient to use to ignite smoking material received by the smoking pipe and such that the smoking assembly has an aesthetically-pleasing appearance.

Modes For Carrying Out The Invention FIGURES 1-3 disclose a smoking assembly 10 in accordance with a preferred embodiment of the invention. The illustrated smoking assembly 10 includes a housing 12 that defines a first chamber 14 having an open end 16, a second chamber 20 having an open end 22, an elongated channel 24 having an open end 26, and an aperture 28; a first or top cover 30 slidably mounted to one longitudinal end 32 of the housing for opening and closing the open end of the first chamber and for opening and closing the open end of the elongated channel; a second or bottom cover 40 rigidly mounted to the other longitudinal end 42 of the housing for partially enclosing the second chamber; a removable smoking pipe 44 receivable within the elongated channel; and a refillable lighter 46 fixedly contained substantially within the second chamber of the housing. In accordance with a preferred embodiment, the first chamber 14 is adapted to store smoking material 50, and the smoking pipe 44 can be removed from the channel 24 and used to remove a portion of the smoking material 50 from the first chamber 14. The smoking pipe 44 holds the portion of the smoking material for smoking while the portion is being ignited outside the housing 12 by the lighter 46, which emits flame through the aperture 28. Desirably, the aperture 28 is located on a side of the housing 12. The open end 16 of the first chamber 14 and the open end 26 of the channel 24 desirably are disposed at or adjacent the one end 32 of the housing 12, and the open end 22 of the second chamber 20 desirably is disposed at or adjacent the other end 42 of the housing 12. In the illustrated embodiment, the housing 12 includes an inner wall 58 that defines a passage 60 that extends through the housing substantially along the length of the housing. The passage 60 includes the first chamber 14 and the second chamber 20 which are substantially aligned with each other and which may be separated from each other in any suitable manner such as, for example, by a thin spacer 62 which defines the base of the first chamber 14 and which can be used for tamping of the smoking pipe 44. The illustrated spacer 62 is generally rectangular and includes rounded corners to complement the periphery of the inner wall 58. Desirably, the edge of the spacer 62 is curved around its periphery toward the open end 16 of the first chamber 14 to provide a bowl effect to facilitate removal of the smoking material. The elongated channel 24 is defined by an inner channel wall 64 preferably extending substantially the entire length of the housing 12. The elongated channel 24 is substantially parallel to the first and second chambers 14 and 20. The housing may include a plurality of vents 66. The housing 12 may be constructed of any suitable material, such as, for example, aluminum or other metal. The top cover 30 desirably is slidably mounted to the housing 12 in any suitable manner. In the illustrated embodiment, for example, the housing 12 includes a pair of inclined walls 70 and the sides 72 of the top cover 30 are inclined in a complementary manner to engage and permit sliding of the top cover. Preferably, the top cover 30 is adapted to be slid in one direction to open the open end 26 of the channel 24 to allow access to the smoking pipe 44, and in the other direction to open the open end 16 of the first chamber 14 to allow access to the smoking material 50. The illustrated top cover 30 includes a finger grip in the form of an indentation 73. In a preferred embodiment, the top cover 30 includes a limit in the form of a stud 74 extending from the bottom 76 of the top cover, and the housing 12 defines a pair of opposed contact surfaces 80, 82 for contacting the stud to limit the movement of the top cover 30 in either direction. In the illustrated embodiment, the contact surface 80 is defined by the inner wall 58 at one side of the housing 12, and the contact surface 82 is defined by the inner channel wall 64 at the other side of the housing 12. The housing 12 desirably defines a recess 84 through the inner wall 58 and the inner channel wall 64 for allowing passage of the stud 74 completely therethrough so that the open end 16 of the first chamber 14 is completely open when the stud is slid completely in one direction (e.g., to the right in FIGURE 3). The stud 74 desirably is disposed at a location on the bottom 76 of the top cover 30 such that, when the top cover is slid completely in one direction (e.g., to the left in FIGURE 3) and the stud is in contact with the contact surface 80, the open end 26 of the channel 24 is completely open to allow access to the smoking pipe 44 and the open end 16 of the first chamber 14 remains closed by the top cover; and, when the top cover is slid in the other direction (e.g., to the right in FIGURE 3) and the stud is in contact with the contact surface 82, the open end of the channel is closed by the top cover and the first chamber 14 is completely open to allow access to the smoking material 50. As a result, in accordance with this embodiment, the smoking pipe 44 can be removed from the channel 24 after the top cover 30 is slid completely in one direction (e.g., to the left in FIGURE 3), and can then be used to remove smoking material 50 from the first chamber 14 after the top cover is slid completely in the other direction (e.g., to the right in FIGURE 3). The smoking pipe 44 desirably is hollow and elongated and includes a bowl 90 disposed at one end of the smoking pipe for repeatedly receiving and engaging smoking material 50 for smoking. The smoking assembly 10 desirably further includes a biasing element 92, such as a spring, disposed within the channel 24. The biasing element 92 is compressed by the smoking pipe 44 when the smoking pipe is within the channel 24 and the open end 26 of the channel is closed by the top cover 30 (see, e.g., FIGURE 3). When the open end 26 of the channel 24 is open, the biasing element 92 biases or pushes the smoking pipe 44 so that a portion of smoking pipe extends outside the housing 12 and can be grasped for use. The lighter 46 desirably is constructed to be contained substantially within the second chamber 20 of the housing 12 in a neat and compact manner. In the illustrated embodiment, the lighter 46 is generally rectangular and relatively thin and compact. The lighter 46 includes a lighter housing 100 defining a lighter fluid chamber 102 for storing lighter fluid; an igniter 104 for creating a spark; a valve stem 106 in fluid flow communication with the lighter fluid chamber having a valve 108 adapted to move from a closed position to an open position to release lighter fluid; a lighter switch 110; and a lever arm 112 engaged with the lighter switch and the valve and adapted to move the valve to the open position and to activate the igniter in response to the application of manual pressure to the lighter switch. The longitudinal axis of igniter 104 desirably extends generally perpendicular to the longitudinal axis of the valve stem 106 (see FIGURE 3). This configuration enables the lighter 46 to be positioned within the housing 12 such that a rear portion of the lighter switch 110 is disposed at or adjacent the other end 42 of the housing 12 so that the lighter switch is activatable adjacent the other end of the housing 12. The valve stem 106 is disposed adjacent the aperture 28 of the housing 12 so that the flame emitted from the valve stem passes through the aperture. The igniter 104 desirably includes an elongated igniter housing 114 and a conduit 116 extending from the igniter housing through a conduit support 118 and terminating adjacent the valve stem 106. The illustrated lighter switch 110 is generally L-shaped and includes a base 120 and an arm 122. A boss 124, having a generally square or rectangular cross section, may be included adjacent the base 120. A camming surface 126 is defined at the bottom of the juncture of the base 120 and the arm 122 to activate the igniter 104 as pressure is applied to the lighter switch 110. The lighter housing 100 defines a slot 130 that slidingly receives and engages the arm 122 so that the lighter switch 110 can be moved to activate the igniter 104 and apply pressure to the lever arm 112 to open the valve 108. The lighter 46 also defines a bore 132 and includes a spring 134 received within the bore to apply pressure to the boss 124 during activation of the lighter switch 110 to bias the switch to the unactivated position. The illustrated lever arm 112 desirably is bent, and includes a pair of forked members 140, 142 for receiving the valve stem 106 on one end and the conduit support 118 on the other end. The lever arm 112 also includes a flange 144 on the one end in contact with the bottom of the arm 122. When the lighter switch 110 is activated, a downward force is applied to the flange 144 which causes the one end of the lever arm 112 to move the valve 108 to the open position. A recess 150 may be defined on the bottom of the arm 122 for receiving the flange 144 and the conduit support 118. The housing 12 defines a generally rectangular void 152 contiguous with the second chamber 20 to facilitate manual activation of the lighter switch 110. In the illustrated embodiment, a shell 154, which defines a cavity 156 for receiving a rear portion of the lighter 46 extending outside of the housing 12, is secured to the lighter 46 to enhance the aesthetics of the smoking assembly 10. The shell 154 desirably is constructed of the same material as the housing 12 and substantially fills the generally rectangular void 152. The lighter 46 is activated by applying pressure to the shell 154 such as, for example, by squeezing together the shell and the housing adjacent the other end 42 of the housing. The outer opposed side walls 160 of the housing 12 may include a generally recessed area 162 adjacent the void 152 to receive and slidingly engage the shell 154 and to permit sliding movement of the shell relative to the housing 12 when the lighter switch 110 is being activated. In the illustrated embodiment, the shell 154 is secured to the lighter 46 by a fastener 164, such as a screw. The bottom cover 40 is also secured to the lighter 46 by a fastener 166, such as a screw, and has inclined walls 168 that slidingly engage inclined walls 169 of the housing. The bottom cover 40 may include a lip 170 extending underneath a portion of the shell 154 to facilitate sliding action of the shell relative to the bottom cover. The bottom cover 40 desirably defines an aperture 172 positioned adjacent a lighter fluid port 174 included with the lighter 46 so that lighter fluid can be readily added to the lighter fluid chamber 102. A smoking assembly 210 in accordance with a further embodiment of the invention is illustrated in FIGURES 4 and 5. The embodiment of FIGURES 4 and 5 is similar in several respects to the embodiment of FIGURES 1-3, and, for purposes of brevity, related reference numbers will be used to illustrate the embodiment of FIGURES 4 and 5 (e.g., the reference numbers 210, 212, 214, etc. are used to identify the components of the embodiment of FIGURES 4 and 5 parts which correspond to the components of the embodiment of FIGURES 1-3 identified by reference numbers 10, 12, 14, etc.). The lighter 246 of the smoking assembly 210 of FIGURES 4 and 5 includes the lighter housing 300 defining the lighter fluid chamber 302 for storing lighter fluid; the igniter 304 for creating a spark; the air-fuel chamber 305 including a valve stem 306; the valve 308 in fluid flow communication with the valve stem adapted to move from a closed position to an open position to release lighter fluid from the fluid chamber to the valve stem; a generally J-shaped lighter switch 310; the lever arm 312 engaged with the lighter switch and the valve and adapted to move the valve to the open position and to activate the igniter in response to the application of manual pressure to the lighter switch; and a generally J-shaped frame member 400 on which the air-fuel chamber 305 is mounted. A conduit 401 connects the valve 308 to the air-fuel chamber 305. The lighter housing 300 includes a first mounting arm 402 secured to the frame 400 by a pin 404, and a second mounting arm 406 secured to the lighter switch 310 and to the frame by pins 408 and 409, respectively. The illustrated lighter switch 310 is generally J-shaped and includes a switching arm 410, an activating arm 412, and a side arm 414. The switching arm 410 includes a pair of opposed arcuate surfaces 420 at one end of the lighter 246. The activating arm 412 defines a central slot 422 receiving the first mounting arm 402. Additionally, a roller 424 is mounted to the activating arm 412 within the slot 422 for activating the igniter 304 in response to activation of the switching arm 410, causing the lighter switch 310 to pivot about pin 408. The side arm 414 of the lighter switch 310 also defines a slot 430 substantially along its length for receiving the second mounting arm 406 of the lighter housing 300. The frame 400 defines a bore 432 disposed about the flame emitting end of the valve stem 306, and includes a coil 434 adapted to be heated by the flame and to reignite the flame during windy conditions. Additionally, a shutter 440, secured to the switching arm 410 in any suitable manner, may be included which is adapted to open the bore 432 during activation of the switching arm 410 and close the bore when the switching arm is in the inactivated position. A spacer 442 is engaged with the housing within the elongated channel 224 to define a base of the elongated channel. The bottom cover 240 is secured to the lighter 246 by a pair of fasteners 264, one of which engages the lighter 246 and the other of which engages the spacer 442. The bottom cover 240 may also include opposed camming surfaces 450 to facilitate sliding of the opposed arcuate surfaces 420 of the lighter switch relative to the bottom cover. Accordingly, manual activation of the switching arm 410 creates a flame by simultaneously causing the roller 424 to activate the igniter 304 to create a spark, the lever arm 312 to open the valve 308 and allow lighter fluid to pass through the valve, and the shutter 440 to open the bore 432. The coil 434 reignites the flame during windy conditions. As in the case of the embodiment of FIGURES 1-3, the longitudinal axis of igniter 304 desirably extends generally perpendicular to the longitudinal axis of the valve stem 306. However, in the embodiment of FIGURES 4 and 5, the activating end 460 of the igniter 304 is positioned opposite the end 462 of the lighter 246 (i.e., rotated 180° from the position of the igniter 104 of the embodiment of FIGURES 1-3). The housing 212 includes opposed rounded corners 462 for engaging the opposed arcuate surfaces 420 of the lighter switch 310 to facilitate manual activation of the lighter switch. A pair of windows 470 may be defined on the opposed side walls 260 of the housing 212 to enable the lighter fluid level to be visually determined. In the embodiment illustrated in FIGURES 4 and 5, the housing 212 includes an inner wall 258 that defines the first and second chambers 214 and 220, which extends through the housing substantially along the length of the housing. The spacer 362 may be used to separate the first and second chambers 214 and 220. Alternatively, the flat outer surface 480 of the frame 400 of the lighter 246 may define the bottom of the first chamber 214 and separate the first and second chambers 214 and 220. In the illustrated embodiment, the inner wall 258 defines a lip 482 for engaging the spacer 162. Accordingly, the present invention provides a complete and compact smoking assembly that is easy to use and transport. The housing can store the smoking material, receive the smoking pipe and house the lighter in a neat and compact manner. The lighter desirably is contained within the housing such that it is easy and convenient to use and enables the smoking assembly to have a generally rectangular appearance and aesthetically pleasing appearance.
