Abstract
Abstract A toy figure includes a hollow body having coupling openings formed in its upper side walls and bottom wall, the openings having inwardly tapered conical faces with peripherally spaced longitudinal channels. A magnet slab housed in the body is sandwiched by yoke plates which closely confront each opening. A coupling member having a circular base section with a ribbed conical face engages each opening and includes an inner portion of magnetic material engaged by the yoke plates to releasably retain the coupling members in the openings. An arm is attached to each coupling member for angular movement about an axis perpendicular to the axis of the coupling member base section.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
179 words
An adjustable arm-structure comprising a body member with a wall having formed therein a coupling socket having front and rear openings and being coaxial with a first axis, a magnetic member housed in said body member proximate said socket front opening, a coupling plug coaxially slidably engagable with said socket and movable between an advanced forward position in said socket and a retracted position, said coupling plug and socket having confronting faces separably engagable in said coupling plug advanced position to releasably lock said plug and socket against mutual angular movement about said first axis said confronting faces comprising cooperating ridge means and a plurality of channel means, wherein said ridge means selectively engages at least one channel means, said coupling plug including a front ferromagnetic section attracted by said magnet member to urge and releasably maintain said coupling plug in said advanced position, an arm member and means connecting said arm member to said coupling plug for swinging only about a second axis transverse to said first axis and angularly adjustable with said plug about said first axis.
Claim 2
Dependent Claim
179 words
An adjustable arm-structure comprising a body member with a wall having formed therein a coupling socket having front and rear openings and being coaxial with a first axis, a magnetic member housed in said body member proximate said socket front opening, a coupling plug coaxially slidably engagable with said socket and movable between an advanced forward position in said socket and a retracted position, said coupling plug and socket having confronting faces separably engagable in said coupling plug advanced position to releasably lock said plug and socket against mutual angular movement about said first axis said confronting faces comprising cooperating ridge means and a plurality of channel means, wherein said ridge means selectively engages at least one channel means, said coupling plug including a front ferromagnetic section attracted by said magnet member to urge and releasably maintain said coupling plug in said advanced position, an arm member and means connecting said arm member to said coupling plug for swinging only about a second axis transverse to said first axis and angularly adjustable with said plug about said first axis.
Claim 3
Dependent Claim
38 words
The structure of claim 1 wherein said coupling socket and plug are circular and the respective confronting faces thereof respectively have regularly spaced ridges and channels which are separably engaged when said plug is in said advanced position.
Claim 4
Dependent Claim
38 words
The structure of claim 1 where said magnet member includes a pair of spaced ferromagnetic plates and a permanent magnet sandwiched between said plates, said plates terminating in end faces defining magnetic poles proximate said socket front opening.
Claim 5
Dependent Claim
30 words
The structure of claim 1 wherein said plug has an inwardly directed face with a well formed therein and said ferromagnetic section includes a ferromagnetic member nesting in said well.
Claim 6
Dependent Claim
25 words
The structure of claim 2 wherein said plug and socket confronting faces are conical and said ridges and channels are mutually engaged and relatively slidable.
Claim 7
Dependent Claim
75 words
The structure of claim 1 wherein said rocket includes a stepped longitudinal bore including an inner section and an outer section of greater diameter than said inner section and delineated therefrom by an outwardly facing first annular shoulder, said coupling plug including a stepped pin having inner and outer sections delineated by a second annular shoulder confronting said first shoulder, said first and second shoulders respectively having mutually separably engaging ridges and groves formed therein.
Claim 8
Dependent Claim
45 words
The structure of claim 1 wherein said coupling plug includes a rearwardly projecting axial post terminating in a transversely extending axle, and comprising a pair of opposing coaxial socket members located at an end of said arm and rotatably engaging respective ends of said axle.
