[0018] Embodiments of the presently disclosed subject matter provide for an improved telescoping stick for testing emergency safety systems.

[0019] FIG. 1 depicts the improved telescoping stick for testing emergency safety systems in use.

[0020] Referring to FIG. 1, a telescoping stick 100 is used for pressing a button on an emergency device such as an exit sign, an emergency light, smoke detector, fire alarm, or the like. The emergency device may be mounted at a height such that it is generally out of reach of the general public, at least without the use of a ladder or other propping device. The emergency device may be mounted, for example, on the ceiling, on a wall near the ceiling, or on pieces that are connected to the ceiling, such as rafters, beams, pipes, or the like. In most instances, the emergency device is mounted at a height of anywhere from 7 feet to 12 feet, although it will be understood that they may be mounted at different heights in different contexts.

[0021] The button being pressed may be a “test” or a “reset” button, or it may be any other type of button that needs to be quickly and efficiently accessed but is just out of reach without a ladder or other similar device.

[0022] FIG. 2 depicts a perspective view of the improved telescoping stick for testing emergency safety systems in an extended position.

[0023] Referring to FIG. 2, the telescoping stick 100 for pressing a button on an emergency device that is mounted at a height comprises three portions. The three portions of the telescoping stick 100 include a handle 202, and extendable portion 203, and a head assembly 204. The handle 202 is located proximate a first end of the telescoping stick 100. The first end of the telescoping stick 100 is the end that is held by the user. The head assembly 204 is located proximate a second end of the stick opposite the first end. The second end of the telescoping stick 100 is the end that presses the button on the emergency device. In other words, the handle 202 and the head assembly 204 are located at or near (collectively “proximate”) opposite ends of the telescoping stick 100. The handle 202 may be any type of handle. The head assembly 204 is described in more detail in the context of FIG. 4.

[0024] The extendable portion 203 connects handle 202 to head assembly 204. One end of extendable portion 203 is mechanically coupled to handle 202. The opposite end of extendable portion 203 is mechanically coupled to head assembly 204. The extendable portion 203 comprises multiple tubular sections 205a, 205b, and 205c arranged in a nesting configuration such that the multiple tubular sections extend in a telescoping manner along a longitudinal axis between the first end of the telescoping stick 100 (i.e., where the head assembly is located) and the second end of the telescoping stick 100 (i.e., where the handle is located).

[0025] The number of tubular sections may vary depending on the particular use case of the telescoping stick 100. In one embodiment, the telescoping stick 100 includes four tubular sections. In other embodiments, the telescoping stick 100 may include more or fewer tubular sections. The tubular sections may all be the same length, or they may vary in length from one another, with the outer, lower-most tubular section being the longest at each tubular section nested inside that one being incrementally shorter than the previous tubular section. It will be understood that overall length of the telescoping stick 100 when in the retracted position is influenced by the length of the longest tubular section, so a shorter retracted stick will have more sections that are each shorter in length, whereas a longer retracted stick will have fewer sections that are each longer in length.

[0026] In one embodiment, the telescoping stick 100 may be approximately seven feet long when fully extended. Having a stick that is seven feet long when fully extended is beneficial because most people's fully extended (unassisted) reach is approximately six to seven feet, so the seven-foot-long stick allows a user to comfortably reach a button as high as 13 or 14 feet, which is higher than the ceilings in most commercial buildings. A telescoping stick 100 that is approximately seven feet long when fully extended may comprise, for example approximately eight inches of handle, approximately four inches of head assembly, and approximately six feet of tubular sections. As mentioned, in one embodiment, there are four tubular sections, with each tubular section being approximately one-and-a-half feet long.

[0027] The extendable portion 203 allows for the telescoping stick 100 to include an extended configuration (as shown in FIG. 2) and a retracted configuration (as shown in FIG. 3). In various embodiments, the multiple tubular sections are non-circular in cross-section, which prevents them from spinning or rotating in the user's hand while the user is trying to apply force to the button. For example, the multiple tubular sections may be square in cross-section. This is particularly beneficial in situations where the button is in a tight or hard-to-reach space, or when it is at an awkward angle.

[0028] Each tubular section slidably engages at least one adjacent tubular section. For example, the tubular sections at each end (e.g., 205a and 205c shown in FIG. 2) each only engage one adjacent tubular section (e.g., 205b shown in FIG. 2). Similarly, the tubular sections in the middle (e.g., 205b shown in FIG. 2) each engage two adjacent tubular sections (e.g., 205a and 205c shown in FIG. 2). The adjacent tubular section slidably engage one another in that they are sized and shaped so that one tubular section fits inside the adjacent tubular section, providing the telescoping action of the tubular sections.

[0029] Each tubular section is releasably locked into place with at least one adjacent tubular section when the telescoping stick 100 is in the extended configuration using cooperating locking means 206a, 206b, and 206c between adjacent tubular sections for restraining movement of the tubular sections relative to one another when engaged. The cooperating locking means may be a spring-loaded button on the inner tubular section and a corresponding aperture on the outer tubular section, as shown, for example, in FIG. 2. In other embodiments, the cooperating locking means may be a force-fit nub and depression, or other well-known engagement means.

[0030] FIG. 3 depicts a perspective view of the improved telescoping stick for testing emergency safety systems in a retracted position.

[0031] Referring to FIG. 3, the tubular sections 205a-205d are shown nested and retracted into one another in a telescoping manner. As shown in FIG. 3, the cooperating locking means are not engaged when the stick 100 is in the retracted position, which allows for easy extension. The cooperating locking means 206a-206c only engage when the stick 100 is in the fully extended position.

[0032] FIG. 4 depicts a perspective view of the rotating head of the improved telescoping stick for testing emergency safety systems.

[0033] The head assembly 204 comprises a ball-and-socket swivel and a button-engagement tip for pressing a button on an emergency device. The ball-and-socket swivel comprises a socket 402 with a ball 403 rotatably engaged in the socket. The ball 403 is able to move or rotate within the socket 402 along any axis. The ball-and-socket swivel has a tightening means for releasably fixing the ball-and-socket swivel at a specified position. As shown in FIG. 4, the tightening means is a threaded rod 407 with a knob 406 at a distal end that allows the threaded rod 407 to be tightened into the socket 402 such that the proximate end of the threaded rod 407 bears against ball 403 and prevents ball 403 from moving, thereby fixing it in a specific position. In other embodiments, the tightening means may be any known way of tightening, such as a screw or a lever that provides a clamping force to the socket 402, which fixes the ball 403 in a specified position.

[0034] Ball 403 of the ball-and-socket swivel may include a connection 404 extending from the ball 403 to provide for a mechanical coupling of the ball-and-socket swivel to the button-engagement tip 407. The connection 404 may be any type of connection as will be understood by a person having ordinary skill in the art. Such connection 404 may allow for the button-engagement tip 407 to be swapped out with other types of tips.

[0035] In some embodiments, as shown in FIG. 4, the walls of the socket 402 may be tall enough such that they surround a majority of the ball 403. In such a situation, the connection 404 may prevent the ball-and-socket swivel from being arranged in a configuration that is perpendicular to the longitudinal axis of the telescoping stick 100. In other words, the connection 404 contacting the walls of socket 402 may prevent the tip from reaching the latitudinal axis of ball 403. For this reason, socket 402 may include a notch 405 that engages with connection 404 to allow the attachment at the end of the ball-and-socket swivel to be oriented perpendicular to the longitudinal axis of the telescoping stick 100, along the latitudinal axis of ball 403.

[0036] Because the entire telescoping stick 100 can be rotated in the user's hand, that means that the user is able to set the button-engagement tip 407 at any angle or orientation relative to the telescoping stick 100.

[0037] The button-engagement tip 407 may be shaped to approximate the size and shape of a human finger, which allows it to easily press buttons that are meant to be pressed by human fingers. In one embodiment, the button-engagement tip 407 may be made of rubber, silicone, or another tacky material that provides for better engagement of the button. In the embodiment shown in FIG. 4, the button-engagement tip 407 includes multiple nubs 408 for further providing grip on the button being pressed.

[0038] The button-engagement tip 407 may be interchangeable for other tips of varying shapes and sizes, as required by the particular application.
