US. Cl. 40-117 20 Claims ABSTRACT OF THE DISCLOSURE A device bearing stored calendar indicia and adapted to form a link of an item such as a watch bracelet, identification bracelet or watch strap. The device is positioned relative to the item so that a portion of the stored information is controllably accessible and easily readable. In the case of a watch bracelet, the device is located so that its stored calendar indicia can be read with facility, as by forming a link between a timepiece and the remainder of the bracelet.
Illustratively, the calendar indicia consist of a series of months which appear on a stripof plastic tape carried by a removable transport mechanism within the device, with the base of the device forming an end link of the bracelet. The tape is'controllably advanced in respective directions of movement by arbors positioned at the extremities of the transport mechanism and connected to the ends of the tape. To maintain the tautness of the tape against a support surface of the transport mechanism, the arbors are rotatably mounted in resilient or springloaded bearings. To prevent rotation of the arbors in the wrong directions the arbors are mounted in bearings which permit at least one end of each arbor to move longitudinally relative to the transport mechanism in one direction and means are provided for preventing further rotation of'each arbor in that direction upon sliding movement of its end in its bearing.
The transport mechanism is held in place with respect to the base by a cover which is attached by a single, centrally positioned spring bar. The cover has a window which provides viewing access to the calendar indicia of the tape. It also has diagonally opposite slots for user access to crowns that are used for rotating the respective arbors and in one embodiment they are also used to prevent rotation of the arbors in the wrong directions.
This application is a continuation-in-part of application, Ser. No. 699,167 filed J an. 19, 1968, which has been abandoned.
BACKGROUND OF THE INVENTION This invention relates to a device which bears calendar indicia and is adapted to form a part of a watch or identification bracelet or watch strap.
The desirability or need of providing a bracelet or strap with calendar indicia has been widely recognized but prior to this invention was not satisfied.
One attempted solution has been to employ a metallic plate that is imprinted with the calendar data of a specified month. The plate is then attached or clipped to the bracelet or strap. Not only is such a plate limited in the amount of calendar information that it can carry, but there is also considerable inconvenience in changing plates at the end of each month. In addition the plate detracts from the overall appearance of the bracelet or strap.
Another approach has been to use an imprinted roller, or similar component, that is included within a linkage of a bracelet, or as an accessory to a strap. Again, the amount of calendar information is limited if the roller Patented Sept. 8, 1970 is to be of manageable size, particularly in the case of watch bracelets and straps which are relatively thin. Alternatively, when the roller information takes the form of a perpetual calendar there are other disadvantages. A perpetual calendar has to be set from a standard calendar, and if there is an accidental change in the setting, the error is not readily detected.
Still another approach has been to include an imprinted strip of tape that is propelled by gearing associated with a rotatable stem. Although the amount of calendar information is increased by the use of such a tape, the gearing makes for mechanical complexity and bulk. This detracts from the appearance of the device and the associated bracelet or strap. Moreover, so far as I am aware, there has been no safeguard against inadvertent or accidental movement of the tape in the wrong direction.
Accordingly, it is an object of the invention to provide a device which bears calendar indicia in convenient and readily accessible form for incorporation into a watch bracelet or strap or an identification bracelet.
Another object of the invention is to enhance the facility with which calendar indicia can be replaceably stored in such a device. A related object is to provide a replaceable calendar unit for a watch bracelet or strap or an identification bracelet. A further related object is to provide an easily replaceable calendar unit in the form of a cartridge.
A further object of the invention is to provide the calendar information of at least one year in a bracelet or strap of limited size, while at the same time maintaining a desired aesthetic appearance for the visible constitutents of the bracelet or strap. An associated object is to avoid the need for gearing, and its attendant cost, bulk and complexity. Another associated object is to maintain the tautness of a tape medium that is used to bear calendar indicia. Still another associated object is to provide a compact calendar unit using a calendar cartridge of small size.
A yet further object of the invention is to limit the possibility of an accidental change in the setting of the device and also the'extent of any improper operation of the device.
SUMMARY OF THE INVENTION In accomplishing the foregoing and related objects the invention provides a device which bears calendar indicia and is adapted to be included in an item such as a watch bracelet.
The device contains a replaceable cartridge mechanism for controllably transporting a strip of tape with respect to the viewing window of a cover. The tape is illustratively imprinted with calendar information, such as the months of a year, and is attached to rotatable arbors that are positioned at opposite extremities of the transport mechanism. The arbors are attached to respective, and diagonally opposite, winding and rewinding crowns which are serrated and accessible through corresponding slits of the cover.
In accordance with one aspect of the invention the arbors are in spring loaded and open-ended bearings. The spring loading of the bearings desirably is provided by flanges that extend outwardly from beneath opposite sides of a tape support surface of the transport mechanism and also serve to centralize the tape on the surface. Because of the spring tension against each arbor, the tape is held taughtly against the support surface beneath the viewing window of the cover. In addition, the axis of rotation of each arbor is below the level of the support surface, with an end of the tape attached so that the tautness. Further enhancement of the desired tautness is achieved by the use of a flexible plastic material, such as polyester film.
According to another aspect of the invention, a base of the device is adapted to serve as the end element of a watch bracelet or watch strap. Taken together, the base and transport mechanism form a support structure for the tape. The tape is positioned on the transport mechanism so that dates of each calendar month are in successive rows that are perpendicular to the edge of the bracelet. Consequently, when the bracelet is attached to a timepiece and positioned on the wrist of a wearer, the calcudar indicia are easily read at a glance.
In accordance with another aspect of the invention, the cover of the device is maintained in position with respect to the base by a single, centrally located spring bar. The central location permits the use of a single spring bar and prevents any interference with the arbors at the extremities of the tape transport mechanism.
Because the bearings of the arbors are open-ended, they guard against the inadvertent rotation of the assoclated winding or rewinding crowns in an improper direction. In one embodiment when such an attempt is made with one of the crowns, the associated arbor backs away from the closed end of the bearing and slides longitudinally towards the open end of the bearing in the direction of rotation of the arbor and the serrated teeth of the crown engage an edge of the corresponding slot in the cover to prevent further rotation. In other embodiments flanges or tabs are provided on either the base or the tape transport cartridge so they are spaced from the serrated teeth of the crowns when the arbors are seated in the closed ends of the bearings but which are engaged by the teeth of the crowns when the arbors slide longitudinally of the bearings as they are rotated in the wrong directions.
Other aspects of the invention will become apparent after considering three illustrative embodiments thereof, taken in conjunction with the drawings.

DETAILED DESCRIPTION OF THE FIRST EMBODIMENT Turning to the drawings, FIG. 1 shows a calendar device 100 included as an end link of a watch bracelet 200, which is joined to a timepiece 300 in conventional fashion.
The calendar device 100 is advantageously located in the bracelet 200 for ease of readability and has the same width as the remainder of the bracelet. In addition, a cover 110 of the calendar device 100 is contoured for continuity of the overall lines of the bracelet when it is positioned on the wrist of a wearer.
As discussed at length subsequently, the calendar device contains a removable tape transport cartridge 140 (FIG. 3) which serves as a transport mechanism for a strip of tape 141 with imprinted calendar indicia, for example, the dates of the twelve months of a calendar year. Only the dates of one month at a time are visible through a viewing window 111 of the cover 110.
One end of the calendar tape is coupled to an internal arbor 142 that has a serrated winding crown (144 protruding slightly through a slot 115 in the cover 110. The tape is wound, and thus advanced, by rotating the crown 144. If the wearer wishes to consult the device 100 for an elapsed date, the calendar tape is rewound, to the extent desired, by the counter rotation of a serrated rewinding crown 145. The latter has an internal arbor 143 that is coupled to the other end of the calendar tape. The two crowns 144 and 145 are diagonally positioned near opposite edges of the cover 110. The spacing between the crowns 144 and 145 lessens the likelihood of accidental advance or rewind of the calendar tape.
Since the cover 110 is removable, there is ready access to the tape transport cartridge and, hence, to the calendar tape, both of which are replaceable. Moreover, the device is structured to maintain the tautness of the calendar tape, and its arbors are mounted to limit the extent of any incorrect rotation of the corresponding crowns 144 and 145.
As demonstrated in the exploded view of FIG. 2, the calendar device 100, has in addition to the cover 110, a base and a separable cartridge 140, which together form an overall support structure for a calendar strip 141. When the device is assembled, the cover 110 is held in place on the support structure by a single spring bar 101 that is centrally located in the base 120.
Considering first the structure of the base 120, it is to be noted that watch bracelets are conventionally attached to timepieces by so-called end hooks. Hence the base 120 of the calendar device acts as an elognated endhook base or liner for the bracelet 200.
For joinder of the base 120 to the remainder of the bracelet 200, one end bears a loop 121. The opposite end of the base 120 has a loop 122 for joinder to the timepiece 300 (FIG. 1).
Attachment of the end loop 121 to the bracelet is made by connecting members 201, of which only one is shown in FIG. 2. Each connecting member 201 includes a leg having a detent 201-a that is gripped by the interior of the loop 121. The other leg 201-b of the connecting member is inserted into the end link 202 of the expansible portion of the bracelet between the end of a fiat spring 202-a and an inner surface of the top wall of the link 202 as shown in US. Pat. No. 3,307,348 which issued Mar. 7, 1967 on an application of Wallace F. Vanover.
Illustratively, the entire portion of the bracelet beyond the calendar device including the links 203 may be made in accordance with the linkages shown in the aforesaid Vanover patent or in US. Pat. No 2,689,450 which issued Sept. 21, 1954 on an application of Karl E. Stiegele. It will be apparent to persons skilled in the art, however, that other types of expansible linkages, or non-expansible linkages with releasable center clasps, may be used.
At the other end of the base 120 the hook 205 is rolled about loop 122. The former is proportioned to bridge the space between a pair of arms (not shown) which extend outwardly from the timepiece 300 (FIG. 1). Attachment of the base assembly 120 to the timepiece is by a standard spring bar 301 which passes through the loop 122. The ends of the spring bar are received in recesses (not shown) in the arms of the timepiece.
Between the end loops 121 and 122, the bottom of the base 120 has a raised central section 123 and oppositely positioned side walls 124 and 125. The walls 124 and 125 bear centrally located apertures 126 for the ends of the spring bar 101. When the calendar device 100 is assembled the cartridge is placed between the side walls 124 and 125 straddling the raised central section 123.
From FIG. 2 it is seen that the cartridge 140 carries a strip of tape 141 which is partially wound on two oppositely located arbors 142 and 143. The first arbor 142 carries a serrated crown 144 for winding and advancing the tape to expose the calendar data of succeeding months in linear sequence. The other arbor 143 has a serrated crown 145 for rewinding the tape in order to expose elapsed calendar data when desired. The arbors 142 and 143 are held in position by spring flanges 146 and 147 in the manner discussed in detail below in conjunction with the description of FIG. 3.
The final constituent of the calendar device 100 is the cover 110. It has a central window 111 for a snap-in crystal 112. The latter is convexly contoured to provide magnification of the calendar data and is held in place within the cover 110 by oppositely located side detents 113. Diagonally positioned slots 114 and 115 provide the wearer of the assembled calendar device 100 with access to the crown stems 144 and 145. In assembly, the spring bar 101 is centrally positioned in the base with its spring loaded tips extending through the apertures 126 of the base into associated cover apertures 116.
The central location of the spring bar 101 permits the cover 110 to be held in place using a single retainer, avoids interference with the advance and rewind arbors 142 and 143 and promotes compactness of the resulting calendar device 100.
After assembly of the calendar device 100, flanges 112-a of the viewing window 112 of the cover 110 straddle the calendar tape 141 and rest on the exposed upper side surface of the cartridge 140. This limits any up-and-down motion of the cartridge.
Referring to the details of the calendar cartridge 140 illustrated in FIG. 3, the tape strip 141 is advantageously a thin film of material such as polyester. Polyester material is flexible and able to adapt to the contour of the support portion 148-a of platform 148 in the cartridge 140. A suitable polyester tape is marketed and sold by the E. I. du Pont de Nemours & Co. under the trademark Mylar. The tape is tailored to form the strip 141 and imparted with the desired calendar indicia, either by a regular printing process or by the well known silk screening technique.
For clarity, the arbors 142 and 143 in FIG. 2 have been withdrawn from extensions 148-b of the support platform 148. The arbors 142 and 143 receive respective ends (not visible in FIG. 3) of the tape strip 141 in standard fashion. Thus, the ends of the tape strip can be tapered and inserted into slits in the arbors or, alternatively, the ends may be attached to the arbors by a pressure sensitive adhesive, either directly or by having an intermediate section of pressure sensitive tape between each arbor and the associated tape end.
In readying the cartridge 140 of FIG. 3 for operation, the arbors 142 and 143 are snapped into place between the lower ends of the spring flanges 146 and 147 and the upper ends of the extensions 148-b of the platform 148. The extensions 148-b are located below the level of the support surface 148-a of the platform 148 and are joined to the support surface by shoulders 148c. Each of the extensions 148-a forms a receptacle of suflicient depth to hold an arbor after being maximally wound with the tape 141. One of the spring flanges in FIG. 3, namely the flange 147, has been exploded from the platform 148 in order to show its structural details.
In use, both spring flanges 146 and 147 are centrally attached on the underside of the platform 148, near respective edges, in standard fashion. Consequently the ends of the flanges are freely movable relative to the extension 148-b of the platform 148. For example, the ends 147-a and 147-b of the flange 147 are transversely movable through associated lever arms 147-0 and 147-d with respect to their attachment portion 147-e.
The bearing surface of each spring flange 146 or 147 for the crown end of each anbor 142 or 143 has a twosided notch 146 or 147-;f; however the bearing surface for the other end of the arbor 142 or 143 includes a positioning detent 146-g or 147-g. Because of the 1ocation of each extension 148-b relative to the cartridge 148, the axis of rotation of each arbor is below the level of the support surface 148a. The attachment of the strip 141 to the arbors is such that the strip bears against shoulders 148-c regardless of the extent to which it has been wound on either arbor. Instead of being wound under the arbors as shown in FIG. 3, the strip 141 may be wound over the arbors.
In addition, the ends of the spring flanges 146 and 147 serve as peripheral guides for the calendar tape 141, keeping it centralized on the platform 148.
It is by virtue of the location of the arbors 142 and 143 and the use of the spring flanges 146 and 147 that the tape strip 141 is held tautly in place during and after each advance. The spring tension of the flanges 146 and 147 and the contact of the tape with the shoulders 148-c of the platform 148 tend to prevent any release of the tautness of the strip 141 once the rotational force applied to either crown 144 or 145 is removed. When such force is applied, the direction of advance of the tape strip 141 is in an opposite sense to the direction of rotation. Where the strip 141 is wound over the arbors, the direction of advance of the strip is in the same sense as the direction of rotation. The extent of the spring tension applied by the flanges 146 and 147 is controlled in accordance with the dimensions of the associated lever arms, e.g. the arms 147-0 and 147-d of the flange 147. Further, the location of the flanges 146 and 147 relative to the extensions 148-b gives rise to open-ended or three-sided bearings for the arbors 142 and 143, which, because of the disposition of the serrated crowns 144 and 145 in the slots 114 and 115 of the cover (FIG. 2), prevent the user of the calendar device from rotating the crowns in the wrong direction. When such rotation is attempted, the crown end of the arbor backs away from the front of the bearing and towards the open side, causing the serrated crown 144 or 145 of the arbor to engage the back edge of the associated slot 114 or 115 in the cover 110. This prevents further rotation of the arbor.
DESCRIPTION OF THE SECOND EMBODIMENT In FIG. 4, the base and the tape transport cartridge 140 are of the same constructions as in FIGS. 1 to 3 except that an inwardly extending flange or tab 124-11 is provided on the side wall 124 of the base 120. This flange is spaced from the teeth of the crown 144 when its arbor 142 is against the front of its bearings but when the crown is rotated in the wrong direction, the arbor slides longitudinally of the bearing between 147-b and 148b, the teeth of the crown engage the tab 124-a and further rotation of the arbor in that direction is prevented.
A similar tab or flange (not shown) is provided on the side wall extending inwardly adjacent to the crown 145.
In this embodiment, the slots 114 and 115 in the cover are made slightly longer than in the embodiment of FIGS. 1-3 because they are not relied upon to prevent rotation of the arbors in the wrong directions.
DESCRIPTION OF THE THIRD EMBODIMENT In FIG. 5 an upwardly and outwardly extending flange or tab 148-d is provided on the bottom wall of the cartridge v120. This flange is spaced from the teeth of the crown 144 when its arbor 142 is against the front of its bearings but when the crown is rotated in the wrong direction, the arbor slides longitudinally of the bearing between 147-b and 148-b, the teeth of the crown engage the tab 148-d and further rotation of the arbor in th direction is prevented.
The slot 148e in the bottom wall of the cartridge 140 is substantially parallel to the upwardly extending portion of the flange 148-d. In FIG. the extremity of this slot which is adjacent to the end of the element 148-b is hidden by the upwardly extending portion of the flange 148-d but the slot extends to the far side of the bottom wall between the end of the element 148-17 and the upwardly extending portion of the flange 148-11 and consequently the strip of the bottom wall which is between the slot and the flange 148d can be deflected downwardly manually to permit insertion of the arbor into the open end of the bearing formed between 147-b and 148-12 without interference between the teeth of the crown 144 and the outwardly extending portion of the flange 148-d. After the arbor has been inserted in the bearing and the downward pressure on the flange is released it is moved upwardly by the resilience of the strip of the bottom wall which is between the slot and the flange 148-11 and consequently the outwardly extending end of flange 148-d is then in a position to be engaged by the teeth of the crown 144 when the arbor slides outwardly towards the open end of its bearings.
A tab or flange (not shown) similar to 148-d is provided on the bottom wall at the opposite end of the cartridge adjacent to the crown 145.
In this embodiment as in the second embodiment, the slots in the cover are made slightly longer than in the embodiment of FIGS. 1 to 3.
It will be understood that the specific embodiments of this invention which are disclosed herein are of a descriptive rather than a limiting nature and that various changes, combinations, substitutions, additions and modifications may be made in accordance with the foregoing teachings without departing in spirit or scope from the broader aspects of the invention.
