5 Claims. (01. 70-273) Our invention relates to a cigarette case having a time-controlled locking means, and more particularly to such a case which is adapted for being carried on the person of the smoker such as in a coat pocket, etc.
It is well-known that the smoking of cigarettes tends to become a fixed habit, and that for many smokers there is a tendency to progressively increase the number of cigarettes smoked during a given period of time until such smoking becomes excessive and therefore detrimental to the health of the smoker. An extreme form of this type of smoking habit is sometimes referred to as chain smoking. As will readily be understood, there are widely varying degrees of chain smoking, but the general condition is that the smoker tends to light one cigarette after another in rather rapid succession. As with any ingrained habit, the act of reaching for and lighting the next cigarette tends to become automatic and to be carried out without conscious attention. Thus, it is very difficult for a person who has reached the chain smoking stage to decrease his consumption of cigarettes so long as there is a supply of cigarettes readily available to him. Studies have indicated as with other types of drug habits that the best method of overcoming chain smoking is to present a hindrance to smoking which causes the lighting of a cigarette to be a matter of conscious choice, and then to gradually space out the smoking of cigarettes over intervals of. time of increasing length.
It is therefore an object of our invention to provide a cigarette case which will normally remain locked, but which will become unlocked at spaced intervals of time in order that a smoker who desires to decrease the number of cigarettes smoked will be hindered from automatically lighting a cigarette without conscious attention. It is a further object of our invention to provide a cigarette case having a timing mechanism therein which will cause the lid to be opened at periodic intervals while allowing the whole case to be sufliciently compact to be carried in the pocket. It is another object of our invention to provide a latch structure for a cigarette case which is normally locked but which can be periodically opened by a clock-mechanism actuating a camming member. It is also an object of our invention to provide an adjustment for the camming member in our cigarette case which will allow the opening mechanism to be set to open the case over varying selected time intervals, and particularly over evenly spaced time intervals. Further objects and advantages of our invention will appear as the specification proceeds.
Our invention is shown in an illustrative embodiment in the accompanying drawings, in Which- Figure 1 is a perspective View of the exterior of a cigarette case or container embodying the mechanism of our invention; Fig. 2, a perspective view similar to Fig. 1 showing the cigarette ease partially open; Fig. 3, a perspective view of the closure or lid which houses the clock mechanism showing the latch pin in its closed position; Fig. 4, a fragmentary perspective view of the top portion of the cigarette case to which the closure member shown in Fig. 3 attaches; Fig. 5, a front cross-sectional view taken in elevation on line 5-5 of Fig. 1 showing the clock-operated unlocking mechanism. Fig. 6, a developed view of the camming projections affixed to the rotating plate shown in Fig. 5; Fig. '1, a cross-sectional bottom view taken on line !I of Fig. 5 showing the relationship of the parts of the latch operating mechanism; Fig. 8, a bottom cross-sectional view taken on line 8-8 of Fig. 5 showing the relationship of the parts of the clock mechanism; Fig. 9, a side crosssectional view taken in elevation on line 9-9 of Fig. 7 showing the means for adjusting the distance between the projection-bearing plate and the camming member; Fig. 10, a side cross-sectional view taken in elevation on line Ill-I0 of Fig. '7 showing further details of the clock mechanism; and Fig. 11, a side cross-sectional view taken on line I l-l of Fig. '7 showing the top closure covering the opening in the case and locked thereto.
In the illustration given, It generally desighates a container or case providing a compartment ll therein for storing cigarettes l2. It will be understood that case H) can be made in various shapes, but preferably compartment H is made of sufficient size to receive a package of cigarettes.
Container I0 is provided with an opening 13 to allow cigarettes to be inserted into or removed from compartment l I. It will be understood that opening It can be provided on the sides of container H), as well as at the top asshown. Opening 13 is provided with a cover or lid designated generally as H. In the illustration given, cover l4 includes a housing [5 which provides a compartment IS in which the unlocking mechanism is contained. In the illustration given, housing l5 extends downwardly to provide flanges H with inwardly turned end portions i8 which are received within slots l9 when cover 14 is slid onto 3 the top of case it. If desired, cover [4 can be secured to case ill so as to cover and uncover opening 13 as desired by means of hinges, etc. It is preferred, however, to provide means for securing cover M to case so that these members can be locked together by a single latch.
As shown more clearly in Fig. 11 a latch 2% is provided for locking lid 14 to case it when it is positioned so as to fully close opening it. In the embodiment shown, latch 28 comprises a latch member or pin 22 depending from the bottom of lid 55 and extending upwardly into compartment i%. Fig. ii positions latch in closed or locked position wherein latch pin 22 is in the position shown in Fig. 3. It will be apparent that when latch pin 22 is moved to the right, as shown in Fig. 11, that it will be brought into alignment with a recess 2i in the top of the side of case it and thereby allow cover I l to be partially or completely removed from case It. Thus, it can be seen that this arrangement allows means to be provided within housing 55 to shift latch pin 22 from locked to unlocked position as desired. This means will now be described.
As shown more clearly in Fig. 5, latch pin 22 extends upwardly into compartment i6 and is connected to a lever arm 23. Lever arm 23 is pivotally mounted at 2 3 as shown more clearly in Figs. 5 and '7. In the illustration given, a spring 25 is connected to the free end of lever arm 23 so as to normally hold it in latching position. Lever arm 23 is also provided with a laterally extending camming flange 25.
A rotatably mounted member on plate 2? is mounted so as to rotate below lever arm 23. In the illustration given, plate 2'! is circular in shape has radially spaced camming projections 28 extending downwardly from the outer portions thereof. The shape of projections or lugs 28 is shown best in Fig. 6 where the camming member to the extreme right is the one approaching the bottom and coming into engagement as shown in Fig. 7. camming projections will subsequently be de scribed in detail. It will be noted here, however,
that several of the camming projections 28 are provided with recess 29.
Any suitable camming means can then be provided for causing the spaced projections 22% to periodically shift lever arm 23 suniciently to move latch pin 22 to unlatched position. traticn given, there is provided an angular camming member 36, as shown best in Fig. 7. Camming member 3b is rockably mounted on pin 3i. As shown, camming member 38 is shaped to provide oppositely-disposed camming ends 32 and End 33 is positioned so that its inner surface just engages the under surface of flange 26 when lever arm 23 is in latching position. End 32 has its inner surface inclined at 3'2 and relatively fiat at 35. Thus, when a projection 28 engages inclined surface 34, lever arm 23 will be cammed to unlatching position by the rocking of member 2 6, and held in open position while projection 23 rides over surface 35.
Rotatably mounted plate 2"! can be driven by any suitable clock mechanism such as the mechanism shown which is designated generally as 3%.
Clock mechanism 38 is of a conventional type,
and therefore it is believed that it will not be necessary to describe it herein in 1 detail. As
' shown best in Fig. 5 clock mechanism 36 contains a main spring 3? which is wound by shaft 3% having key 358 attached to the end thereof. Central shaft id is driven through gears by spring 3? In the i1lus- The function of these variously shaped 4 and is maintained at a uniform angular velocity by means of an operable regulating structure, such as the one shown in Fig. 8. In the illustration given, plate 2? is naintained directly on shaft es and thereby rotates in synchronism with shaft 53, and thus is maintained at a uniform angular velocity. For most clock mechanisms and preferably, shaft ll) will make one complete revolution per hour. It will be understood, however, that if as desired the angular velocity of shaft all can be varied, or plate 2? can be driven through gears by timed shaft such as shaft 10.
If desired, shaft 4B can be made to extend upwardly to the top of housing i5 and hands attached thereto to provide a conventional clock 4!. Also, if desired shaft Ml can be extended below lid i4 so that clock 4! can be set.
By the positioning of camming projections 28 at spaced points around the periphery of plate 21, clock mechanism 36 can be made to open latch 20 at predetermined time intervals, while allowing the latch to be maintained in closed position between these intervals. However, it is desired to provide a means for varying the length of the intervals of time during which the cigarette case remains locked, and. particularly to provide means for gradually increasing the length of these intervals. Therefore, in the illustration shown we provide a means for adjusting the distance between angular caniming member 38 and plate 2'5. The particular adjusting means provided is'shown more clearly in Figs. 5 and 9. Pin 3| is equipped with a collar i2 having a spiral ridge or thread 43 extending about its outer surface. A rider 44 having an aperture therein and being interiorly threaded to correspond with threads 43 is secured about collar 42. Pin 3i is then extended below cover i l and equipped with a slotted head or other turning adaptation 45. Thus, when pin 3! is rotated while camming member 30 remains V stationary, camming member 30 will be moved upwardly or downwardly as shown in Figs. 5 and 9 and thereby increasing or decreasing the distance between camming member 36 and plate 27. In order to hold camming member 30 stationary while pin 3| is rotated, there is provided a stop pin 46 as shown best in Fig. 7.
As previously described, camming projections 28 are made of varying lengths. It can now be seen that the variation in-the position of camming member 30 will cause camming member 39 to contact different camming projections. In the illustration given, as shown best in Fig. 6 I provide six camming projections which allow headed pin 3! to be'adjusted so that the cigarette case will be unlocked 1, 2, 3, or a times per hour as desired. These settings are indicated numerically in Fig. 3, and diagrammatically in Fig. 6. The dotted lines in Fig. 6 designated as a, b, c. and d indicate the four positions of 'camming member 35. In one position the camming member 30 will be contacted only by extreme righthand projection 28 which is the longest of the projections, and is shown approaching end portion 32 in Fig. 7. When camming member 39 is adjusted to lie in the plain of-line b, it can be seen that the camming member will be contacted not only by the camming projection to the extreme right but also by the central camming projection. Similarly, when camming member 39 lies in the plain of line 0, it will be engaged by all of the camming members extending downwardly that far except the central camming member, as shown'in Fig. 6 which is provided with a recess 29, so that the case will be opened only at uniformly spaced intervals. Finally, when camming member 30 lies in the plain of line 6! it will contact four of the projections as indicated, but will not engage the two L-shaped cam members which are also provided with recess 29.
If desired lever arm 23 can be provided with an outward extension 41 extending through a suitable slot in a wall of housing [5 by which latch 28 can be opened if it is desired to do so without waiting for the operation of the clock mechanism.
Operation In operating a cigarette dispenser of the type shown, cigarettes are first placed within compartment II as shown in Fig. 2, then the spring of the clock mechanism can be wound by key 39, and pin 3| can be rotated by means of slotted head 45 to position camming member 30 at the desired distance from plate 21. As discussed above, in the illustration shown, this positioning can be made so that latch pin 22 will be moved to open position at intervals of 15, 20, 30, or 60 minutes as desired.
Cover It is then slid onto the top of case Ill so as to completely close opening [3. Lever arm extension 41 can then be used to temporarily move latch pin 22 to the open position so that it can pass through recess 2 I, and when released will move to its locked position because of the tension exerted by spring 25. After having been thus closed and locked latch 20 will remain locked for a predetermined time interval which may be from to 60 minutes in the structure shown.
The particular advantage of the structure shown is that a smoker using such a cigarette case will be aided to overcome a chain smoking habit. This is true because the clock mechanism can be set to unlatch the case at spaced intervals, which can be increased in duration as de sired. It is of particular importance in this connection that the structure allows the spaced intervals to be uniform at a given setting.
While in the foregoing specification, we have set forth structures in great detail for the purpose of illustrating embodiments of our invention, it will be understood that such details of structure may be varied widely by those skilled in the art without departing from our invention.
