The present invention relates to the reinforcement of bands. Various aspects of the invention are particularly related to the reinforcement of watch bands.
The watch industry is continuously seeking to improve the durability of watch bands.
Originally, watch bands were formed from leather or fabric. While these materials were relatively flexible and comfortable, bands made from these materials were not very durable. Exposure to water and continuous wear, for example, will quickly degrade leather and fabric watch bands. To address these deficiencies, some watch makers have created watch bands out of metal links. While metal link watch bands are more resilient than leather and fabric watch bands, they are relatively heavy and expensive.
Recently, more rugged sport watches have become popular, particularly for various activities such as running, boating, diving, and climbing. In order to keep the cost of these watches low while still providing an environment-resistant band, some watch makers have begun using watch bands formed from plastic or rubber. As shown in
To attach the band to a watch, a springbar is inserted into the springbar passage 105, and the pins are pressed into the hollow cylinder. With the pins thus compressed, the attachment portion 103 is inserted between two lugs of a watch casing. Each lug contains a recess for receiving a pin. Accordingly, when the attachment portion 103 is positioned so that the springbar is aligned with the lug recesses, the spring in the springbar forces the pins into the lug recesses to secure the attachment portion 103 between the lugs.
This conventional arrangement securely attaches the watch band to the lugs of the watch casing. With this arrangement, however, the springbar passage 105 is typically formed very close to the end 107 of the attachment portion, as shown in
Aspects of the invention relate to a band with a reinforced construction. With various examples of the invention, a band will have an attachment portion that defines a connector bar passage, a reinforcement pin passage and a reinforcement plate recess intersecting both the connector bar passage and the reinforcement pin passage. The band also will have a reinforcement plate and a reinforcement pin. The reinforcement plate defines a connector bar aperture and a reinforcement pin aperture, and is positioned within the reinforcement plate recess such that the connector bar aperture intersects the connector bar passage and the reinforcement pin aperture intersects the reinforcement pin passage. Typically, the reinforcement plate is formed from a resilient material, such as metal or hard plastic. The reinforcement pin is positioned within the reinforcement pin passage such that the reinforcement pin extends through the reinforcement pin aperture of the reinforcement plate.
With these implementations of the invention, the reinforcement plate reinforces the wall of material between the connector bar passage and the end of the attachment portion. That is, when the band is pulled away from the lugs, the resilient material forming the reinforcement plate will prevent the connector bar from tearing the material between the connector bar passage and the end of the attachment portion. The reinforcement plate in turn is securely held within its recess in the attachment portion by the reinforcement pin extending through both the reinforcement plate and the reinforcement passage formed in the attachment portion.
As also seen in these figures, the watch band attachment includes two reinforcement plates 211A and 211B. Each reinforcement plate 211 defines a connector bar aperture 213 and a reinforcement pin aperture 215. With various examples of the invention, the reinforcement plates 211A and 211B may be formed from a material that resists tearing, such as a metal, metal alloy, or a relatively hard plastic. The reinforcement plate 211A is inserted into the reinforcement plate recess 209A so that its connector bar aperture 213 intersects the connector bar passage 205 and its reinforcement pin aperture 215 intersects the reinforcement pin passage 207. Similarly, the reinforcement plate 211B is inserted into the reinforcement plate recess 209B so that its connector bar aperture 213 intersects the connector bar passage 205 and its reinforcement pin aperture 215 intersects the reinforcement pin passage 207. As shown in
As a result of this configuration, when the reinforcement pin 217 is inserted into the reinforcement pin passage 207, it passes through the reinforcement pin apertures 215 of both the reinforcement plate 211A and the reinforcement plate 211B, thereby securely holding the reinforcement plates 211A and 211B in their respective reinforcement plate recesses 209A and 209B. As seen in
Turning now to
While a springbar is specifically shown in
As previously noted, the connector bar passage 205 is relatively close to the side 219 of the attachment portion 203 closest to the watch 221, and thus allows the attachment portion 203 the freedom of movement to rotate around the springbar 227 (or the bolt and cap nut combination) without being obstructed by the watch 221. On the other hand, the tear-resistant material of the reinforcement plates 211A and 211B reinforces the wall of material between the connector bar passage 205 and the side 219 of the attachment portion 203 closest to the watch 221. Still further, the reinforcement pin passage 207 is positioned away from the side 219 of the attachment portion 203 closest to the watch 221. As a result, when the attachment portion 203 is pulled away from the watch 221, the tear resistant material forming the reinforcement plates 211A and 211B will prevent the springbar 227 (or the bolt and cap nut combination) from tearing the softer material of the attachment portion 203 between the connector bar passage 205 and the side 219 of the attachment portion 203 facing the watch 221.
The reinforcement plates 211A and 211B in turn are securely held within the reinforcement plate recesses 209A and 209B by the reinforcement pin 217 extending through both the reinforcement plate aperture 215 and the reinforcement passage 207 formed in the attachment portion 203. Because the reinforcement pin passage 207 is relatively distant from the side 219 of the attachment portion 203 facing the watch 221, the additional material between the reinforcement pin passage 207 and the side 219 of the attachment portion 203 facing the watch 221 will be more resistant to tearing (and the resultant failure) than a conventional watch band arrangement.
While particular examples of a reinforced watch band have been described in detail above, it will be appreciated that there are a variety of alternate constructions that can be used to implement various embodiments of the invention. For example, instead of two reinforcement plates 211, some implementations of the invention may employ three or more reinforcement plates 211 as shown in
While the invention has been described with respect to specific examples including presently preferred modes of carrying out the invention, those skilled in the art will appreciate that there are numerous variations and permutations of the above described systems and techniques that fall within the spirit and scope of the invention as set forth in the appended claims.
