## Abstract

A Brunnian link is a link formed from a closed loop doubled over itself to capture another closed loop to form a chain. Elastic bands can be utilized to form such links in a desired manner. The example device provides a means of creating items using Brunnian links of complex configurations. Moreover, the example kit provides a device that allows for the successful creation of unique linked items.

## Claims

### Claim 1

A loom for creating an item consisting of a series of links, the device comprising:
a base having a length and width; and
a plurality of pins standing up from the base, each of the plurality of pins respectively include a flange near a top surface for holding an elastic link in a desired orientation, and an access groove extending through the top surface, wherein the access groove in each of the plurality of pins faces in a common direction and are arranged in at least three rows spaced a common distance apart in a direction transverse to the length.

### Claim 2 (depends on 1)

The loom as recited in claim 1, wherein the base includes a slot open to the access groove that extends below a first surface of the base to provide access for a tool below the first surface.

### Claim 3 (depends on 1)

The loom as recited in claim 1, wherein the common direction is in a direction transverse to the width of the base.

### Claim 4 (depends on 2)

The loom as recited in claim 2, wherein the access grooves are orientated in a direction common with the corresponding slot.

### Claim 5 (depends on 1)

The loom as recited in claim 1, wherein the access grooves are orientated in a direction parallel with the length.

### Claim 6 (depends on 1)

The loom as recited in claim 1, wherein pins in at least one of the at least three rows include pins that are not aligned in a direction parallel with a width of the base with pins in adjacent ones of the at least three rows.

### Claim 7 (depends on 6)

The loom as recited in claim 6, wherein that at least three rows includes at least one intermediate row disposed between outer rows.

### Claim 8 (depends on 7)

The loom as recited in claim 7, wherein the intermediate row includes pins not aligned with pins in the outer rows.

### Claim 9 (depends on 8)

The loom as recited in claim 8, wherein the outer rows are spaced a common distance from the at least one intermediate row.

### Claim 10 (depends on 1)

The loom as recited in claim 1, wherein the loom includes a first end spaced apart from a second end and the access groove for each of the plurality of pins opens toward the first end.

### Claim 11 (depends on 1)

The loom as recited in claim 1, wherein the flange extends about the pin from a first side of the access groove to a second side of the access groove.

### Claim 12 (depends on 11)

The loom as recited in claim 11, wherein the access groove extends through the flange and the top surface.

### Claim 13 (depends on 1)

The loom as recited in claim 1, wherein the base includes at least one mating feature for connecting a first base of a first loom to a second base of a second loom.

### Claim 14 (depends on 13)

The loom as recited in claim 13, wherein the at least one mating feature is disposed on at least one of a first end and a second end of the first base and the second base.
