An elongated tubular body having a first tubular extension at one end and a second tubular extension at the opposite end. The first tubular extension has a high-intensity light source mounted therein and an opening with the light source being mounted to project a narrow, high intensity light beam through the opening. A cap has light transmitting material covering the opening. The elongated tubular body includes a power supply mounted therein, a switch mounted thereon, and circuitry connecting the switch to the power supply and the power supply to the light source. The switch can be actuated to activate the power supply to supply power to the light source.

A scabbard for carrying a collapsed baton is described. The scabbard comprises a rotatable protective hood.

A heating device, in particular a gas-heating system, including a housing structure and an external housing, the external housing having at least one sidewall and at least one cover, which are able to be fixed in place on the housing structure. The at least one cover is developed to position the at least one sidewall in at least one direction in space relative to the housing structure. A method for mounting a heating device is also described.

A self-defense apparatus includes a sleeve portion and an adapter connected to the sleeve portion. The sleeve portion includes a proximal end surface, an outer side surface, and a distal end surface. The sleeve portion defines an implement-receiving cavity that extends axially into the proximal end surface. The sleeve portion defines an adapter-receiving passage that extends axially into the distal end surface. A proximal portion of the outer side surface defines a handle portion that includes one or more finger grooves. A distal portion of the outer side surface defines an adapter-interfacing body. A first portion of the adapter body is disposed within the adapter-receiving passage. A second portion of the adapter body extends beyond the distal end surface. A distal portion of the second portion of the adapter body defines a conical body.

An interchangeable self-defense device has two self-defense devices and two modular housings, the two self-defense devices are respectively mounted in the two modular housings, and each one of the two modular housings has a mounting structure formed on a side surface of the housing. The two mounting structures of the two modular housings can detachably interlock with each other. With the interchangeable self-defense device, the user may conveniently hold the two self-defense devices together as one piece, and also can quickly switch functions from one self-defense device to another: therefore the user may optimize the defensive strategy to cope with different situations.

An extendable, telescoping multi-purpose baton that holds one or more tools in such a way that a user can use the baton and another tool at the same time while at least one hand remains free. The baton is extended by a propulsion mechanism permitting controlled speed and force of extension. The telescoping mechanism may be electrically or pneumatically operated and can be extended with sufficient speed and force to deliver a blow or jab when impacting the target, at a distant significantly longer than the user's arm length, permitting use from a safe distance.

A self-defense apparatus includes a sleeve portion, an adapter portion connected to the sleeve portion, and a weapon. The sleeve portion includes one of a fastener or a fastener-receiving passage. The sleeve portion includes a proximal sleeve portion, a distal sleeve portion, a proximal end surface, an outer side surface, and a distal end surface. The sleeve portion defines an implement-receiving cavity that extends axially into the proximal end surface. The proximal end surface and a proximal portion of the outer side surface define a handle portion of the sleeve portion. The distal end surface and a distal portion of the outer side surface define a distal sleeve portion having an adapter-interfacing body of the sleeve portion. The adapter portion includes the other of the fastener and the fastener-receiving passage. The adapter portion defines an adapter body. The weapon is defined by the adapter body and the adapter-interfacing body.
