Abstract
Abstract In a toy assembly kit two elements are to be connected with one another. They are superimposed and have juxtaposed first surfaces and second surfaces which face away from one another. Registering apertures are provided in both elements. An elongated connecting member extends through both of the apertures and is turnable therein. It has a head portion which engages the second surface of one of elements and a free end portion provided with projections which are receivable in response to turning of the connecting member in corresponding recesses provided in the inner circumferential surface of the aperture in the other element or in the second surface of the other element. Thereby, the elements are connected against separation but can be turned with reference to one another.

Claim 1
Independent Claim
333 words
A connecting arrangement for use in a toy assembly kit, comprising a first element having first and second surfaces and a first aperture extending between said surfaces; a pair of additional elements separably connectable interchangeably with said first element and having first surfaces adapted to be placed adjacent to the first surface of said first element, second surfaces, and apertures extending between the respective first and second surfaces of said additional elements and movable interchangeably into register with said first aperture, the configuration of said second surface of one of said additional elements being different from the configuration of the corresponding surface on the other additional element; and a connecting member for separably connecting said first element with a selected one of said additional elements, said connecting member having a first end portion movable into abutment with the second surface of said first element, a median portion insertable into said first aperture, and a second end portion having at least one first projection extending transversely of the longitudinal axis of said connecting member, said first projection having a first engaging surface arranged to engage the second surface of one of said additional elements when the first surface of said one additional element is adjacent to the first surface of said first element and said second end portion extends through the aperture of said one additional element; said second end portion further having at least one second projection also extending transversely of the longitudinal axis of said connecting member and angularly offset with reference to said first projection, said second projection having a second engaging surface at a different level than said first engaging surface relative to the longitudinal axis of said connecting member, and said second engaging surface being arranged to engage the second surface of the other additional element when the first surface of said other additional element is adjacent to the first surface of said first element and said second end portion extends through the aperture of said other additional element.
Claim 2
Dependent Claim
333 words
A connecting arrangement for use in a toy assembly kit, comprising a first element having first and second surfaces and a first aperture extending between said surfaces; a pair of additional elements separably connectable interchangeably with said first element and having first surfaces adapted to be placed adjacent to the first surface of said first element, second surfaces, and apertures extending between the respective first and second surfaces of said additional elements and movable interchangeably into register with said first aperture, the configuration of said second surface of one of said additional elements being different from the configuration of the corresponding surface on the other additional element; and a connecting member for separably connecting said first element with a selected one of said additional elements, said connecting member having a first end portion movable into abutment with the second surface of said first element, a median portion insertable into said first aperture, and a second end portion having at least one first projection extending transversely of the longitudinal axis of said connecting member, said first projection having a first engaging surface arranged to engage the second surface of one of said additional elements when the first surface of said one additional element is adjacent to the first surface of said first element and said second end portion extends through the aperture of said one additional element; said second end portion further having at least one second projection also extending transversely of the longitudinal axis of said connecting member and angularly offset with reference to said first projection, said second projection having a second engaging surface at a different level than said first engaging surface relative to the longitudinal axis of said connecting member, and said second engaging surface being arranged to engage the second surface of the other additional element when the first surface of said other additional element is adjacent to the first surface of said first element and said second end portion extends through the aperture of said other additional element.
Claim 3
Dependent Claim
80 words
A connecting arrangement as defined in claim 1, wherein said second projection of said connecting member is freely insertable into and withdrawable from the aperture of said one additional element and said one additional element has a recess through which said first projection is free to pass in a predetermined angular position of said one additional element with reference to said connecting member during introduction or withdrawal of said second end portion from the aperture of said one additional element.
Claim 4
Dependent Claim
78 words
A connecting arrangement as defined in claim 1, wherein the aperture of one of said additional elements is an elongated slot and forms part of an undercut groove in said other additional element, said groove having at least one open end, and said second end portion of said connecting member being insertable into said groove by way of said open end while said first projection is in at least substantial alignment with the longitudinal direction of said groove.
Claim 5
Dependent Claim
41 words
A connecting arrangement as defined in claim 1, wherein said second end portion is provided with a pair of first and second transversely extending projections, located substantially diametrally opposite each other with reference to the longitudinal axis of said connecting member.
Claim 6
Dependent Claim
18 words
A connecting arrangement As defined in claim 1, wherein at least one of said elements is a plate.
Claim 7
Dependent Claim
25 words
A connecting arrangement as defined in claim 1, wherein the apertures of said first element and said one additional element have a substantially circular outline.
Claim 8
Dependent Claim
29 words
A connecting arrangement as defined in claim 1, wherein said first end portion of said connecting member is provided with means for facilitating angular adjustment of said connecting member.
Claim 9
Dependent Claim
27 words
A connecting arrangement as defined in claim 7, wherein said means for facilitating angular adjustment of said connecting member is provided with a recess of polygonal outline.
Claim 10
Dependent Claim
29 words
A connecting arrangement as defined in claim 1, wherein the axial length of said median portion exceeds the distance between the first and second surfaces of said first element.
Claim 11
Dependent Claim
75 words
A connecting arrangement as defined in claim 1, wherein said first element is of substantially L-shaped profile and has a first arm provided with said first and second surfaces of said first element, and a second arm projecting beyond said second surface of said first arm by a predetermined distance in direction away from said first surface, the axial length of said first end portion of said connecting member at least approximating said predetermined distance.
Claim 12
Dependent Claim
21 words
A connecting arrangement as defined in claim 10, wherein said first end portion has an opening dimensioned to receive a shaft.
Claim 13
Dependent Claim
54 words
A connecting arrangement as defined in claim 1, wherein the configuration of said first projection is different from the configuration of said second projection, said first projection arranged to engage only the second surface of said additional element and said second projection arranged to engage only the second surface of said other additional element.
