The present invention relates generally to water safety devices, and more particularly to a location indicator assembly and to a flotation device, such as a life jacket, equipped with the location indicator assembly.
Water safety devices include flotation devices, such as life vests, life jackets, flotation rings, etc. Such water safety devices are required for individuals on boats, ships and even aircraft in case of an emergency resulting in an individual being thrown into the water. Life vests are integral life saving devices to prevent drowning. The mandated bright orange color of the life vest provides an aid for search and rescue responders to visually identify individuals floating in open water. However, since a significant portion of a life vest would be submerged when worn, very little of the orange color may be visible from a distance, especially in rough water conditions.
Moreover, while flotation devices may reduce drowning risks, many waterborne activities carry other risks as well. Collisions between watercraft, such as boats, personal watercraft, etc., poses a serious danger. Activities such as the use of personal watercraft, water skiing, etc., may often involve repeated entries into the water by participants. For example, while the water skier is making a run, most of the water skier's body is above the water, and the skier can be easily seen by watercraft operators. However, if the water skier falls, only their head and a portion of their torso may be above the water, making it difficult for watercraft operators to identify and avoid the water skier. Such poor visibility may lead to collisions between the watercraft and individuals in the water.
In a first aspect, the present invention provides a location indicator assembly providing high visibility for an individual floating in open water.
In an embodiment, the location indicator assembly includes a support mechanism for undergoing movement between a retracted position and a deployed position, an indicator device mounted to the support mechanism, and means for deploying and retracting the support mechanism to place the indicator device between deployed and retracted states, respectively.
In exemplary embodiments, the support mechanism comprises a scissor link mechanism, and the indicator device comprises a pendant or flag.
The location indicator assembly further includes a housing structure on which the support mechanism is mounted for undergoing movement between the retracted and deployed positions. The housing structure has guide slot, an anchor pin, a base pin, and a pivot pin. The support mechanism comprises a plurality of links including a pair of upper links to which the indicator device is connected and a pair of lower links. One of the lower links is connected to the base pin of the housing structure for undergoing pivotal movement relative thereto, and the other of the lower links has a sliding pin for undergoing sliding movement within the guide slot of the housing structure.
According to an embodiment of the present invention, the means for deploying and retracting the support mechanism includes a latch member, first and second biasing members, and a second biasing member, and deployment and retraction cable assemblies. The latch member is mounted to the pivot pin of the housing structure for undergoing movement between an unpivoted position and a pivoted position to latch and unlatch the sliding pin. The first biasing member biases the latch member to the unpivoted position. The deployment cable assembly is connected to the latch member for applying a pulling force to pivot the latch member to the pivoted position against a biasing force of the first biasing member. The second biasing member interconnects the sliding pin to the anchor pin of the housing structure. The retraction cable assembly is connected to the sliding pin for applying a pulling force to slide the sliding pin along the guide slot of the housing structure against a biasing force of the second biasing member.
According to a feature of the present invention, in the retracted position of the support mechanism in which the indicator device is in a retracted state, the sliding pin is retained by the latch member against the bias of the second biasing member. Upon application of a pulling force by the deployment cable assembly, the latch member is pivoted about the pivot pin and against the biasing force of the first biasing member to unlatch the sliding pin so that sliding pin is permitted to undergo sliding movement along the guide slot to cause the support mechanism to undergo movement to the achieve the deployed position in which the indicator device is in the deployed state.
According to another feature of the present invention, in the deployed state of the indicator device, upon application of a pulling force by the retraction cable assembly, the sliding pin is caused to slide towards the latch member against the biasing force of the second biasing member until the sliding pin is latched by the latch member to place the support mechanism in the retracted position in which the indicator device is in the retracted state.
In a second aspect, the present invention is directed to a flotation device equipped with the location indicator assembly of the present invention. In one embodiment, the flotation device is a life jacket.
In an embodiment of the present invention according to the second aspect, the life jacket comprises a vest and the cable assemblies and corresponding pull handles of the location indicator assembly are mounted relative to the vest such that the pull handles are positioned in a waist region of the vest so as to be readily accessible by the user's hands for deploying and retracting the support mechanism to place the indicator device between deployed and retracted states. In an alternative embodiment, the cable assemblies and corresponding pull handles of the location indicator assembly are mounted relative to the vest such that the pull handles are positioned in a neck and/or chest region of the vest so as to be readily accessible by the user's hands for deploying and retracting the support mechanism to place the indicator device between deployed and retracted states.
These and other aspects, features and advantages of the present invention will become apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings.
The disclosure will provide details in the following description of preferred embodiments of the invention with reference to the following figures wherein:
Embodiments of the present invention provide high visibility for an individual floating in open water by providing a wearable flotation device, such as a life jacket, equipped with a location indicator assembly having an indicator device that can be readily deployed by the individual wearing the flotation device. Moreover, when not in use the indicator device can be readily retracted by the individual so that it does not interfere with activities of the individual while wearing the flotation device.
Turning to
The structural configuration of location indicator assembly 104 according to an embodiment of the present invention is described below with reference to the embodiment show in
Location indicator assembly 104 includes a housing structure 4 with first and second opposite sides 4a, 4b, a support mechanism 112 mounted at a first end thereof to first side 4a of housing structure 4 for undergoing movement between a retracted position (
In this embodiment, housing structure 4 is in the form a generally rectangular-shaped plate provided with a guide slot 7 extending from first side 4a to second side 4b and along the length of the rectangle (as shown in
Support mechanism 112 includes links 113 arranged in the form of a scissor link mechanism (
The mechanism for deploying and retracting support mechanism 112 includes a latch member 15, a retraction cable assembly 110, and a deployment cable assembly 122. Latch member 15 is mounted to pivot pin 20 on the second side 4b of housing structure 4 for undergoing pivotal movement relative thereto. A first biasing member (e.g., leaf spring) 21 is mounted to second side 4b of housing structure 4 at support points 21a, 21b for biasing latch member 15 to the position shown in
Deployment cable assembly 122 is connected at a terminal end thereof to an anchor point 19 of latch member 15. Retraction cable assembly 110 is connected at a terminal end thereof to sliding pin 9 associated with link 113d of support mechanism 112 as described above. A second biasing member (e.g., coil spring) 11 is connected at opposite ends thereof to sliding pin 9 and anchor pin 10 of housing structure 4 for biasing sliding pin 9 towards a right side of guide slot 7 as shown in
In this embodiment, each of the retraction cable assembly 110 and deployment cable assembly 122 may be in the form of a Bowden cable arrangement including an inner cable arranged to move relative to a hollow outer cable housing. For example, retraction cable assembly 110 includes an inner retraction cable 12 configured to move relative to a hollow outer cable housing 13 and having the terminal end connected to sliding pin 9 as described above. Deployment cable assembly 122 includes an inner deployment cable 16 configured to move relative to a hollow outer cable housing 17 and having the terminal end connected to anchor point 19 of latch member 15 as described above. At an end opposite its terminal end, cable 16 is attached to a deployment or release pull handle 120 accessible to and configured to be handled by individual 100 to pull cable 16 outwardly from the individual's body to deploy support mechanism 112 and place indicator device 106 in the deployed or released state (
Location indicator assembly 104 may be removably coupled to flotation device 102 or may be an integral component of flotation device 102. In the present embodiment, flotation device 102 is in the form of a life jacket in the form of a vest worn by individual 100 as shown in
In the embodiment shown in
An embodiment of the operation of location indicator assembly 104 to deploy and retract indicator device 106 during use by individual 100 wearing flotation device 102 equipped with location indicator assembly 104 is described below with reference to the drawings.
Prior to deployment of indicator device 106, flotation device 102 worn by individual 100 and equipped with location indicator assembly 104 is in the configuration shown in
To initiate the deployment procedure, using the right or left hand the individual 100 pulls handle 120, and thus cable 16, away from the individual's body. Pulling of cable 16, which is attached to anchor point 19 of latch member 15, causes latch member 15 to pivot in a clockwise direction about pivot pin 20 until sliding pin 9 is caused to be released from retaining portion 15a of latch member 15 under the biasing action of second biasing member 11. Specifically, sliding pin 9 slides along guide slot 7 due to the action of second biasing member 11 until sliding pin 9 reaches the right side of guide slot 7 as shown in
Retraction of indicator device 106 is initiated from the configuration of location indicator assembly 104 shown in
In the embodiment shown in
In the embodiment shown in
It will be appreciated from the foregoing description of the present invention according to the foregoing embodiments that in the deployed state, indicator device 106 provides high visibility for an individual floating in open water. Deployment of indicator device 106 can be readily achieved by a simple pulling action of pull handle 120, 208 by either the individual wearing flotation device 102 equipped with location indicator assembly 104 or by another individual in the proximity of the individual wearing flotation device 102. Likewise, retraction of indicator device 106 can be readily achieved by a simple pulling action of pull handle 108, 204 by either the individual wearing flotation device 102 or another individual in the proximity of the individual wearing flotation device 102. This permits retraction of indicator device 106 (and thus support mechanism 112) when location indicator assembly 104 is not in use so that support mechanism 112 and indicator device 106 do not interfere with activities of the individual while wearing flotation device 102. This ability to be able to readily deploy and retract indicator device 106 as needed (i.e., on demand) is a feature of the present invention.
The embodiments described herein disclose location indicator assembly 104 used in conjunction with flotation device 102 in the form of a life jacket. However, it is understood that location indicator assembly 104 can be used in conjunction with other types of flotation devices, either wearable or non-wearable, without departing from the objectives and scope of the present invention.
Moreover, location indicator assembly 104 can be used in conjunction with other than flotation devices used in water environments. For example, location indicator assembly 104 is also adapted for use in conjunction with clothing garments, such as vests and jackets, for use in environments other than water environment, such as amusement parks, to provide high visibility for users wearing such garments. For example, such garments equipped with location indicator assembly 104 are suitable for use by children of small age, elderly individuals suffering from dementia, and individuals with special needs who are at high risk of getting lost in crowded environments, such as amusement parks. The deployment of indicator 106 provides high visibility, allowing such individuals to be readily identified and located in case they are lost in a crowd. It also allows such individuals to be easily identified, followed and tracked while walking in crowded environments, even if they are not lost.
