Four types of telescoping modules are disclosed wherein the first type has a pair of opposed female ends, the second type has a pair of opposed female ends, and the third type has a female end and an opposed male end. The fourth type has two opposed male ends between which a positionable threaded rod and retaining components stably extend the length between the male ends of the telescoping module. Alternatively, the fourth type of telescoping module may have a female end and a male end. Each of the male ends of the second, third, and fourth types of telescoping modular components comprises a cylindrical body with one or more linear set(s) of two or more spaced-apart prongs on the circumferential surface of the cylindrical body. Each of the female ends has a cylindrical receptacle with one or more linear channels and/or prong-retaining slots for receiving therein the cylindrical body.

A telescopic bracket has a retracted state and an extended state. The telescopic bracket comprises a fixed assembly, a moving member, and a spring. The moving member is movably coupled to the fixed assembly to move along an axial direction of the fixed assembly, causing the telescopic bracket to switch between the retracted state and the extended state. The spring is disposed between the fixed assembly and the moving member to provide an elastic restoring force to the moving member, and the cross section of the spring could be a trapezoidal shape, a rectangular shape, a square shape, a parallelogram shape, or an unequal quadrilateral shape. An open-up device using the telescopic bracket is also provided.

The compression-mounted shower grab bar incorporates a grab bar, a plurality of mounting plates, a plurality of mounting caps, and a shower. The shower further comprises a first wall and a second wall. The compression-mounted shower grab bar is adapted for use by a client. The compression-mounted shower grab bar forms a structure the client can grasp for improved stability. The compression-mounted shower grab bar mounts between the first wall and the second wall of the shower. The plurality of mounting caps secures the grab bar to the plurality of mounting plates. The grab bar applies a compressive force that presses the plurality of mounting plates against the first wall and the second wall such that the grab bar is: a) secured to a fixed position in the shower; and, b) transfers the load of the client to the first wall and the second wall.

The present invention discloses a telescopic rod connector, which includes an outer sleeve, an inner sleeve and a screw rod. The screw rod has opposite a first end and a second end, and a rod body between them. The inner sleeve sleeves on the rod body and can rotate and slide along it, and the inner sleeve is provided with positioning convex strips. The outer sleeve includes a notch ring and a plurality of outer arc members extending from the notch ring. U-shaped notches are arranged between adjacent two the outer arc members; the outer sleeve is arranged on the outside of the inner sleeve and the notch ring is close to the first end, and the positioning convex strips are inserted into the U-shaped notches. The outer sleeve is rotated to drive the inner sleeve to slide along the rod body.

A button assembly for a telescopic hot stick is provided. The button assembly comprises a button housing, a button, and a fastener. The button housing defines a cavity and at least one groove, and the cavity has a bottom cavity surface. The button is disposed in the cavity and the button has a first end and a second end. The second end is configured to face the bottom cavity surface. The fastener is disposed within the at least one groove, and the fastener is positioned adjacent the second end of the button. The fastener is spaced apart from the second end to collectively define a gap between the second end and the fastener.

Systems and methods for capturing unmanned aircraft and controlling post-recovery motion of the aircraft are disclosed herein. An aircraft system in accordance with one embodiment of the technology, for example, includes a base assembly and an aircraft capture member attached to and extending from the base assembly. The aircraft capture member has a distal region positioned to intercept an unmanned aircraft in flight. The aircraft capture member comprises an elongated telescoping rod including a plurality of discrete segments having a telescoping arrangement relative to each other. The aircraft capture member is configured to elongate or pay out from a first initial length to a second extended length greater than the first length after an unmanned aircraft intercepts and engages the distal region of the aircraft capture member.

An improved telescoping stick for testing emergency safety systems is disclosed. The telescoping stick retracts so that the user can easily carry the stick throughout a commercial building without inconveniencing the people in the building, and it extends so that the user can easily reach test or reset buttons on emergency devices, such as emergency lights and exit signs. The end of the improved telescoping stick includes a rotatable tip on a ball-and-socket swivel that allows the tip to be orientated in any direction to reach a button of any configuration.

Provided is a leg retention clip for a leg of a tripod and a tripod assembly that includes the leg retention clip. The leg retention clip can be inserted inside a hollow-out inside of a first leg section with slots/holes which output protruding edges of the leg retention clip. When a second leg section is fitted over the first leg section, the protruding edges of the leg retention clip can stop movement of the second leg section and help lock the second leg section in place with respect to the first leg section. If the leg of the tripod includes more than two leg sections, the leg can be provided with multiple leg retention clips.
