## Abstract

A toy connector in accordance with the present invention joins first and second structural elements which are aligned adjacent one another and engaged to form a flush, secure connection having a female connector assembly joined to the first structural element having at least two recess elements and at least one female snap element disposed between the recess elements, and a male connector assembly joined to the second structural element having at least one tongue adapted to engage each of the recess elements, and at least one male snap element adapted to engage the female snap element.

## Claims

### Claim 1

A male and female connector for joining first and second structural elements which are aligned adjacent one another and engaged to form a flush, secure connection, comprising:
(a) a female connector assembly joined to said first structural element having,
(i) at least two recess elements, and
(ii) at least one female snap element disposed between said recess elements; and
(b) a male connector assembly joined to said second structural element having,
(i) at least one tongue adapted to engage each of said recess elements, and
(ii) at least one male snap element adapted to engage said female snap element; and
said recess elements and said female snap element comprise,
a continuous web joined to and extending from said first structural element;
a plurality of flange elements joined to and extending from said structural element and substantially parallel to and spaced apart from said web to form said recesses; and
a lug joined to a distal portion of said web between said recess element to define said female snap element, said lug adapted to engage said male snap elements.

### Claim 2 (depends on 1)

The connector of claim 1 in which each of said male snap elements comprises:
(a) a resilient tab joined to and extending from said second structural element; and
(b) a lug joined to the distal end of said tab, said lug being adapted to engage said female snap element.

### Claim 3 (depends on 1)

The connector of claim 1 further comprising at least one stop means for restraining movement of said tongues.

### Claim 4 (depends on 1)

The connector of claim 1 further comprising a stop means joining said web and said flange of each recess element for restraining movement of said tongues.

### Claim 5

A male and female connector for joining first and second structural elements which are aligned adjacent one another and engaged to form a flush, secure connection, comprising:
(a) a female connector assembly joined to said first structural element having,
(i) two recesses elements, and
(ii) a female snap element disposed between said recess elements; and
(b) a male connector assembly joined to said second structural element having,
(i) at least one tongue adapted to engage each of said recess elements, and
(ii) a male snap element adapted to engage said female snap element; and said recess elements and said female snap elements comprise:
a continuous web joined to and extending from said first structural element;
a first flange joined to and extending from said first structural element, substantially parallel to and spaced apart from said web to define a first recess;
a second flange joined to and extending from said first structural element, substantially parallel to and spaced apart from said web to define a second recess which is spaced apart from said first recess; and
a lug joined to a distal portion of said continuous web between said first and second recesses to define said female snap element, said lug being adapted to engage said male snap elements.

### Claim 6 (depends on 5)

The connector of claim 5 in which said male snap element comprises:
(a) a resilient tab joined to and extending from said second structural element; and
(b) a lug joined to a distal portion of said tab, adapted to engage said female snap element.

### Claim 7 (depends on 5)

The connector of claim 5 further comprising at least one stop means for restraining movement of said tongues.

### Claim 8 (depends on 5)

The connector of claim 5 further comprising a stop means joining said web and said flange of each recess element for restraining movement of said tongues.

### Claim 9

A toy construction set having a connector for joining a coupling member and a second structural element which are aligned adjacent one another and engaged to form a flush, secure connection comprising:
(a) a female connector assembly joined to said coupling member having,
(i) at least two recess elements, and
(ii) at least one female snap element disposed between said recess elements; and
(b) a male connector assembly joined to said second structural element having,
(i) at least one tongue adapted to engage each of said recess elements, and
(ii) at least one male snap element adapted to engage said female snap element; and
each of said recess elements and said female snap elements comprise:
a continuous web;
a first partition member depending from said continuous web;
a first flange joined to said first partition member so as to be substantially parallel with and spaced apart from said web to define a first recess with said web;
a second partition member depending from said continuous web and spaced apart from said first partition member;
a second flange joined to said second partition member so as to be substantially parallel with and spaced apart from said web to define a second recess with said web; and
a first lug joined to said web between said first and second recesses, said lug adapted to engage said male snap element.

### Claim 10 (depends on 9)

The toy construction set of claim 9 in which each of said male snap elements comprises:
(a) a resilient tab joined to and extending from said second structural element; and
(b) a lug joined to a distal portion of said tab, adapted to engage said female snap element.

### Claim 11 (depends on 9)

The toy construction set of claim 9 further comprising at least one stop means for restraining movement of said tongues.

### Claim 12 (depends on 9)

The toy construction set of claim 9 further comprising a stop means joining said web and said flange of each recess element for restraining movement of said tongues.
