An adapter for a cylindrical end cap of a multi-section locking baton. The adapter has a non-cylindrical outer side surface thereby providing the end of the baton with a non-cylindrical outer side configuration, such as a wedge shape or a domed shape.

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.

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.

An expandable baton including a handle tube having a proximal end, a distal end, and a channel extending between the proximal end and the distal end. The expandable baton further includes a striking rod dimensioned to slide within the channel and having a retention end. In addition, the expandable baton further includes an end cap attached to the proximal end of the handle tube. The end cap includes a well chamber with a retention magnet that is configured to attract the striking rod. The retention magnet retains the collapsed position by attracting the striking rod. The well chamber also has a collar that is separated from the retention magnet by a determined distance, such that there is a separation between the collar and the retention magnet. The collar is configured to abut the retention end of the striking rod while the expandable baton is in a collapsed position.

A glass smasher with a rapidly removable protective cover is mounted at one end of a portable object. When a user holds the portable object and presses the front end (i.e., the smashing cone) of the smashing rod of the glass smasher forcibly against a to-be-smashed glass obstacle, the rear section of the smashing rod will be struck such that the smashing cone is instantly driven to smash the glass obstacle. The protective cover can be mounted around the front end of the glass smasher to store the entire smashing cone in the protective cover. When the protective cover is not pulled, the sliding sleeve of the protective cover is pushed by a packing spring and hence pushes a plurality of engaging elements into engagement in the engaging groove of the glass smasher, thereby preventing the protective cover from inadvertent detachment from the front end of the glass smasher.

The present invention is to provide a positioning control mechanism applied to an expandable baton including a first pipe provided with a clamping groove portion on two opposite inner walls thereof and a second pipe inserted into the first pipe and provided with shifting holes on two opposite wall surfaces thereof. The positioning control mechanism includes an activating mechanism and a releasing rod. The activating mechanism is formed by two activating blocks movably positioned in the shifting holes and hooked with each other to form a releasing hole therebetween. The releasing rod is mounted inside the first pipe and, when one end of the releasing rod is inserted into the releasing hole, the outer edges of the activating block can be retracted inwardly and is not inserted in the clamping groove portion, so the second pipe can be retracted into the first pipe and positioned to form a short-rod shape.
