Abstract
Description
- The present invention is directed generally to coupling assemblies for coupling a wristworn device to a strap, and in particular, to an improved spring bar assembly for facilitating the removal and attachment of the strap to the wristworn device. In a preferred embodiment, the wristworn device is a wristwatch but as will be understood from the disclosure herein, the invention is not so limiting.
- Constructions for watchband couplings are well-known. For example, one known construction is described in U.S. Pat. No. 2,901,806. However, this construction is less than desirable for at least three (3) reasons. One perceived drawback is that this prior art construction includes a less than optimally shaped actuator element, which makes it remarkably more difficult and less reliable to use as a spring bar assembly for a wide range of conventional type strap and band combinations. Secondly, it is believed that the construction of this prior art coupling device would fall apart once it is removed from between the lugs of the wristworn device. In addition, this prior art construction is not meant to be inserted into the strap as with a conventional spring bar.
- Another known prior art spring bar construction is described in U.S. Pat. No. 5,483,505. However, this construction too has perceived deficiencies. For example, it requires a much more precise construction than is desirable, in that it requires that the operating rod, which is perpendicularly assembled to the inner rod, protrudes through an opening (slot) of the outer shaft. Requiring such precise alignment of the operating rod with the slot of the outer shaft during assembly and usage is less than desirable.
- It is thus believed that further advances to the state of the art are both desirable and achievable. In particular, it is desirable to provide users with an ability to more easily couple and decouple a strap to and from a wearable device, such as a wristwatch by way of example. Accordingly, such constructions and methodologies for spring bar assemblies in accordance with the present invention are set forth herein.
- It is thus an objective of the present invention to overcome the perceived deficiencies in the prior art.
- For example, it is an objective of the present invention to provide a spring bar assembly that facilitates the changing of a strap for a wristworn device as well as the coupling and decoupling between the device and the strap.
- Another objective of the present invention is to provide a spring bar assembly that permits a user to more easily change a strap for the wristworn device without using tools or having special knowledge of the spring bar construction.
- Still another objective of the present invention is to provide a spring bar assembly that provides for easy and user friendly usage with a wide range of conventional type straps and bands without the use of the unnecessary and/or extra coupling elements.
- Yet another objective of the present invention is to provide a spring bar assembly that does not fall apart when disassembled from between the lugs of the wristworn device, thus securing and maintaining the integrity of the spring bar assembly even after decoupling from the wristworn device.
- Further objects and advantages of this invention will become more apparent from a consideration of the drawings and ensuing description.
- The invention accordingly comprises the features of construction, combination of elements, arrangement of parts and sequence of steps which will be exemplified in the construction, illustration and description hereinafter set forth, and the scope of the invention will be indicated in the claims.

For example, in a preferred specific, the edges ofsecond end 30 oftubular member 20 may be bent inwardly (creating an annular flange) about “A,” andsecond end member 40 may include an annular shoulder 41 which is “caught” by the lip created at thesecond end 30 so as to prevent thesecond end member 40 from uncoupling from thetubular member 20 when thespring bar assembly 10 is removed from between lugs of a wristworn device. - In accordance with a specific embodiment of the present invention and depicted in
FIG. 1 , thefirst end member 35 is integrally formed with thefirst end 25 of thetubular member 20. This manufacturing feature of a onepiece tubular member 20 and integrally formedfirst end member 35 facilitates the manufacturing process of the spring bar assembly. Alternatively however, and as illustrated inFIG. 2 , thefirst end member 35 need not be integrally formed with thefirst end 25 of thetubular member 20. For example, in this latter embodiment ofFIGS. 2A , 2B and 2C, thefirst end member 35′ may be a press-fit insert and press-fit into (i.e. at) thefirst end 25′ of thetubular member 20. In addition to such press-fitting or instead thereof (i.e. in the case of a non-integrally formed first end), thefirst end member 35′ may be glued, soldered and/or welded at thefirst end 25′ of thetubular member 20. - Reference is now made to
FIG. 3 for a discussion of yet another spring bar assembly, generally indicated at 10A, constructed in accordance with another preferred embodiment of the present invention. Here, and similar to the aforementioned embodiments,spring bar assembly 10A includes a tubular member generally indicated at 20A having a first end generally indicated at 25A and a second end generally indicated at 30A.Assembly 10A also includes a first end member generally indicated at 35A at thefirst end 25A of the tubular member 20A, wherein thefirst end member 35A comprises a firstaxial pin 36A extending from thefirst end 25A of the tubular member 20A; and a second end member generally indicated at 40A at thesecond end 30 of thetubular member 20, thesecond end member 40 comprising a first end generally indicated at 42A and a second end generally indicated at 44A, with a second axial pin 45A extending from the first end 42A of thesecond end member 40A.Assembly 10A also includes a biasingmember 50, again preferably in the form of a spring, positioned within the tubular member 20A. Biasingmember 50 likewise biases the second axial pin 45A towards (i.e. relative to) the firstaxial pin 36A. However, thisFIG. 3 embodiment differs from the embodiments ofFIGS. 1 & 2 in that the retractor, i.e. indicated by 60A, is connected to thesecond end member 40A.Retractor 60A likewise facilitates the urging of the second axial pin 45A towards the firstaxial pin 36A. Importantly, it can be seen thatretractor 60A does not extend through thetubular member 20, as in the case of the prior art construction of U.S. Pat. No. 5,483,505. Therefore, the construction as disclosed herein significantly simplifies the manufacturing process by not requiring such precision manufacturing and assembly of thespring bar assembly 10A of this embodiment. in this embodiment ofspring bar assembly 10A, thesecond end 30A of the tubular member 20A and thesecond end member 40A are likewise cooperatively shaped (as in the aforementioned embodiments) to prevent thesecond end member 40A from uncoupling from the tubular member 20A when thespring bar assembly 10A is decoupled from between first and second lugs of a wristworn device. - In addition, and similar to the aforementioned embodiments, the
first end member 35A may likewise be integrally formed with thefirst end 25A of the tubular member 20A, thus providing the advantages set forth above. Alternatively, as discussed above, thefirst end member 35A need not be integrally formed with thefirst end 25A of the tubular member 20A, and thus may be constructed as set forth above with respect to the description ofFIGS. 2A , 2B and 2C, the features and construction of which are also intended to apply to this embodiment ofFIGS. 3A , 3B and 3C as well. - Reference is thus now made to the embodiment of
FIG. 4 (e.g.FIGS. 4A , 4B, 4C) of a spring assembly, generally indicated at 10B, in accordance with yet a further preferred embodiment of the present invention. Here, spring assembly 10B is similar to that of the embodiment ofFIG. 3 , yet in this embodiment, the first end member and firstaxial pin 35B is formed from a deep-drawing process. That is,tubular member 20B undergoes a deep-drawing process as would be known in the art, in order to form thefirst end member 35B. In all other material respects, spring assembly 10B functions and is constructed functionally identical to the embodiment ofFIG. 3 . - Reference is now made to
FIGS. 5A , 5B and 5C (collectively “FIG. 5”) in connection with a spring bar assembly, generally indicated as 10C, in accordance with yet a further embodiment of the present invention. Here, spring bar assembly 10C is functionally similar to that of spring bar 10B, although the retractor, generally indicated at 60C, is connected to the outer side of the tubular member 20C, similar to that ofspring bar assembly 10 as illustrated inFIGS. 1 & 2 . - In all of the embodiments, the biasing
member 50 may be wedged between the first and second end members (e.g.FIG. 2B ) or may be wedged at one or both ends against an internal flange of the tubular member (e.g. seeend 35B ofFIG. 4B ). - Reference is thus next made collectively to
FIGS. 6-9 , which illustrate constructed assemblies in accordance with preferred embodiments of the present invention, most specifically, coupling a conventional wristworn device with a strap using the respective embodiments of the spring bar assemblies disclosed herein. - Generally, and applicable to all the assemblies,
FIGS. 6-9 each depict a conventional wristworn device in the nature of a wristwatch, generally indicated at 1, which is coupled to a conventional strap, generally indicated at 2. Applicable to each of the embodiments and all the figures generally, it can be seen that each respective first axial pin of each of the spring bar assemblies is dimensioned to be received in a recess in an inner face of afirst lug 3 and each respective second axial pin of each of the spring bar assemblies is dimensioned to be received in a recess in an inner face of asecond lug 4. The shapes and sizes of the respective axial pins is one of design choice, as illustrated herein. The respective biasing members (e.g. spring 50) of each of the spring bar assemblies along with the respective retractors of the preferred embodiments, permit the first (or second) axial pin to be biased towards and away from the second (or first) axial pin (as the case may be). The use of first and second axial pins is by illustration only, as such terms are interchangeable as would be understood from a reading hereof. In this way, no special tool is needed to remove the spring bar assemblies of the present invention from the strap and/or from between the lugs. - The strap used in connection with the present invention may be comprised of multiple sections, for example, if a buckle is being utilized or may be of one piece as would be understood in the art. In accordance with a preferred embodiment, each side of the wristworn device (e.g. at the 6:00 and/or the 12:00 positions) preferably includes a spring bar assembly as disclosed herein to couple a first strap end of
strap 2 to the device 1.FIGS. 6-9 by example and not limitation, show the present invention only at the 6:00 position, It can also be seen thatstrap 2 includes the first strap end, generally indicated at 2A. Strap end 2A includes a slot 2C through which the spring bar assembly of each respective embodiment of the present invention is inserted and positioned, which is a very different construction and arrangement from that described in U.S. Pat. No. 2,901,806. - To fully take advantage of the benefits of the present invention,
strap 2 will include a cut-out section (i.e. slot) 6 so that the respective retractors as disclosed herein may extend therethrough and be easily accessible by the fingers of a user's hand. The precise position and location of the retractors and slots is somewhat of design choice. As can be seen by comparing theslots 6 in the respectiveFIGS. 6-9 , the position of the particular slot will most likely depend on the particular embodiment of the spring bar assembly being used therewith. - As can be seen from the foregoing as well as the figures, the present invention provides an improvement over prior art constructions in that the user can more easily change the straps for the wristworn device without using tools or having special knowledge of the spring bar construction.
- While other attempts have been made to achieve the objectives herein, such attempts have been seen to be, among other things, more expensive and more complicated.
- Thus, the present embodiment provides for a more user friendly construction and methodology to allow for the exchangeability of the spring bar, a feature and advantage not achievable with the present state of the art as well as the other advantages and benefits explicitly and inherently noted above.
- Although the wristworn devices discussed and disclosed herein are preferably a wristwatch, this is by example and not limitation. That is, the wristworn device for use with the present invention may be in the form of and/or have functionality related to blood pressure, heartrate, altitude, temperature or compass measurements, barometric pressure, (and/or combinations of any of the foregoing), just to name a few.
- It can thus be seen that the present invention provides for improved spring bar constructions for coupling of a wristworn device to a strap. It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efficiently attained and, since certain changes may be made in the above constructions without departing from the spirit and scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
- It should also be understood that the following claims are intended to cover all of the generic and specific features of the invention described herein and all statements of the scope of the invention that as a matter of language might fall therebetween.
