LACE ADJUSTER

Abstract

An adjustable lace assembly includes a lace, a tubular member, two stop members, and two spaced apart inserting pins. The lace is composed of two separate lace segments each having a tagged end and an opposite bent end portion. The tubular member has a passage for receiving the bent end portions. The stop members are mounted pivotally inside the tubular member at two axially spaced apart positions and span the passage. Each of the stop members has an engaging part engageable with one of the bent end portions. The inserting pins are insertable removably into the tubular member, are capable of disengaging the bent end portions, respectively, from the engaging parts of the stop members, and permit movement of the bent end portions so that a length between the tagged end of each of the lace segments and a corresponding one of the stop members can be adjusted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 3 and 4, the preferred embodiment of an adjustable lace assembly 100 according to this invention is shown to be applied to a shoe body 200 that has a plurality of eyelets 210. The adjustable lace assembly 100 includes a tubular member 10, two stop members 30, a lace 4, two inserting pins 21, and a cover member 50.

The tubular member 10 is formed as a tube having a substantially oval cross-section, and includes a surrounding wall 12 defining a passage 11 extending in an axial direction (L), two pairs of diametrically opposite pin-inserting holes 125, and two pairs of diametrically opposite pivot holes 126. The surrounding wall 12 has opposite first and second open ends 121, 122, an inner surface 123 extending between the first and second open ends 121, 122, and an outer surface 124 opposite to the inner surface 123. The two pairs of the pin-inserting holes 125 are spaced apart from each other in the axial direction (L) between the first and second open ends 121, 122. Each pair of the pin-inserting holes 125 extends through the inner and outer surfaces 123, 124. Each pair of the pivot holes 126 is positioned between one of the first and second open ends 121, 122 and a corresponding pair of the pin-inserting holes 125.

The stop members 30 are inserted into the passage 11, and each of the stop members 30 is jointed pivotally into one pair of the pivot holes 126. Each of the stop members 30 includes a plate 33 having two pivoting ends 31 protruding oppositely and inserted into the pivot holes 126, respectively, and an engaging part 32 extending between the pivoting ends 31. The engaging part 32 of each of the stop members 30 has two teeth 321 spaced apart from each other and protruding away from one of the first and second open ends 121, 122 of the surrounding wall 12. In the preferred embodiment, the stop members 30 are made of a metal plate.

The lace 4 is composed of two separate lace segments 40. Each of the lace segments 40 includes a tagged end portion 42 having a tagged end 421, and an opposite bent end portion 41 having an adjusting end portion 411 opposite to the tagged end portion 42. The bent end portions 41 of the lace segments 40 are inserted into the passage 11 of the tubular member 10. Each of the bent end portions turns around one of the stop members 30 and is adapted to engage the engaging part 32 of said one of the stop members 30.

Each of the inserting pins 21 is insertable removably into one pair of the pin-inserting holes 125 to disengage the bent end portion 41 of one of the lace segments 40 from the engaging part 32 of a corresponding one of the stop members 30 so that the bent end portion 41 is permitted to move for adjustment of a length between the tagged end 421 of each of the lace segments 40 and a corresponding one of the stop members 30. In this embodiment, the inserting pins 21 are formed as one piece and have a U-shaped connection 22 therebetween.

The cover member 50 covers the tubular member 10, and includes two open ends 51 extending beyond the first and second open ends 121, 122 of the surrounding wall 12 of the tubular member 10, respectively. The cover member 50 has two pairs of diametrically opposite through holes 52. Each pair of the through holes 52 is aligned radially with one of the pairs of the pin-inserting holes 125. In the preferred embodiment, the cover member 50 is made of a plastic material.

Referring to FIGS. 5 and 6, in assembly, the bent end portions 41 of the lace segments 40 are inserted into the passage 11 of the tubular member 10 via the first and second open ends 121, 122, respectively until the bent end portions 41 of the lace segments 40 are disposed between the pin-inserting holes 125. The inserting pins 21 are inserted into the pin-inserting holes 125 correspondingly, and the stop members 30 are inserted into the passage 11 of the tubular member 10 and are jointed pivotally into the pivot holes 126 correspondingly so as to finish the assembly of the adjustable lace assembly 100.

The adjustable lace assembly 100 is installed on the shoe body 100 by stringing the lace segments 40 through the eyelets 210. If the overall length of the lace 4 is too long, the bent end portion 41 of each of the lace segments 40 can be guided around the corresponding one of the inserting pins 31 by pulling the adjusting end portion 411 of each of the bent end portions 41 out the tubular member 10. In this manner, the length between the tagged end 421 of each of the lace segments 40 and a corresponding one of the stop members 30 can be adjusted to a desirable length.

Referring to FIGS. 6 and 7, after adjusting the lengths of the lace segments 40, the inserting pins 31 are removed from the pin-inserting holes 125 so that the bent end portion 41 of each of the lace segments 40 abuts against the engaging part 32 of a corresponding one of the stop members 30. When the adjusting end portion 411 of each of the lace segments 40 is further pulled, each of the stop members 30 can rotate so as to stop the bent end portion 41 of a corresponding one of the lace segments 40. Finally, the adjusting end portions 411 of the lace segments 40 that extend out of the tubular member 10 can be cut for aesthetic purposes.

While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
