.6 Claims. (01. 24-198) Thisinvention relates to adjustable straps for garments and more particularly to slide and loop- 15 of threading operations'is particularly difllcult because each opening is already occupied by one stretch of the strap and also because the leading end of the strap is apt to become bunched or frayed as it is passed through one opening after '20 another. It is necessary, moreover, to stitch the strap to prevent dislodgment of the first formed loop because the second loop has extensive rubbifig engagement with the first loop, and will pull the first loop out when the slide is adjusted unless 25 the first loop is positively retained in place by stitching.

It is an object of the present invention to avoid the necessity for stitching the first loop in place. To this end, provision is made of a slide 30 having four successive, distinct slots, the two inner slots being separated by a central tongue orcrossbar about which the inner strap loop is passed, and the two outer slots being separated from the inner slots and adapted to receive the as strap when it is looped through the second time.

' Theinner slots are narrow and are adapted to bend the strap sharply and to bind it quite snugly so that no stitching is necessary. A further factor tending to obviate the stitching vis the fact 40 that the first and second strap loops do not pass throughv the same slots and do not, therefore, have substantial frictional engagement with one another.

A further object of the invention is to provide a novel slide construction which obviates. the

- necessity'for threading the strapends through the slots or openings in the slide and which, in-

stead, enables the strap to be slid into each slot 50 edgewise through a narrow passage extending into the slot through the periphery of the slide. As applied to the inner slots of the slide embody-'- ing this invention, this feature has the further. advantage that the inner slots may be made nar- 55 rowel l' Since the Strap 1 be observed that the inner ribbon loop which 55 inserted edgewise into a slot through which it could not be threaded.

In accordance with a further feature of the invention the provision of slots for facilitating the insertion of the ribbon is applied also to the loop which forms part of the shoulder strap.

Other objects and advantages will hereinafter appear.

In the drawingforming part of this specification, and illustratingcertain preferred embodiments thereof,

Figure 1 is a fragmentary front elevation illustrating a portion of an undergarment having a shoulder strap embodying features of the invention applied thereto;

Figure 2 is a fragmentary view in elevation and on a larger scale than Figure 1 illustrating more in detail the slide and loop construction of Figure 1;

Figure 3 is a longitudinal, sectional view of the structure of Figure 2, the section being taken on the line 3-3 of Fig. 2 looking in the direction of the arrows; I

Figure 4 is a perspective view of the slide disclosed in the preceding figures;

Figure 5 is a perspective view of another form of slide embodying features of the invention;

Figure 6 is a perspective view of the loop disclosed in Figures 1 to 3; and

Figure! is a perspective view of another form of loop embodying features of the invention.

In'the embodiments of Figures 1 to 4 and 6 disclosure is made of an undergarment I having a strap length or ribbon 2 secured thereto. The ribbon is passed through the lower opening 3 of a loop 4 and doubled back on itself, both ends of the ribbon being stitched to the undergarment. A second strap length or ribbon 5 is passed through an upper opening 6 of the loop 4. One end of this ribbon is passed successively through slots I and 8 of a slide 9, the ribbon end passing.

stitched to the back of the garment.

When it is desired to shorten' or lengthen th shoulder strap the slide 9 is seized and slid up or down theouter stretch of the ribbon 5. It will embraces the cross-bar llihas very slight conbe impossible. The narrower the slots- I and 8- tact with the outer ribbon loop I4, and hence there is little tendency for the inner loop to be dislodged when the length of the shoulder strap is adjusted.

The. chief item of expense which has been involved in prior adjustable shoulder straps has been the cost of assembling the slide and loop with the ribbon. One reason why this operation has been expensive has been that the ribbon had to be threaded repeatedly through the same openings of the slide. with both the slidev and loop, moreover, the ribbon had to be threaded through endwise just as a needle is threaded and this operation could not be performed rapidly, particu-.

larly if the ribbon ends were at all frayed or bunched.

In accordance with the present invention, each of the slots l2 and I3 can be entered from the periphery of the slide through an obliquely extending narrow passage l5 having a flared mouth.

The passage l5 inclines inward from the end of the slot to facilitate the smooth and continuous passage of the ribbonin through the passageii and across to the end of the slot remote from the passage. The obliqueness of the slot further causes the end of the passage which communicates with the slot to be disposed between the ends of the slot so that an overhanging shoulder I 8 is formed behind which the trailing edge of the inserted ribbon may be located and by which it may be retained.

Each of the slots 1 and 8 communicates at one end thereof with the periphery of the slide through a passage I I. The passage i1 is located out of alignment with the slot and an oblique portion I8 is provided for guiding the ribbon into the slot. A shoulder I9 on the slide extends across the end of the slot to retain the inserted ribbon. With this construction, the assembly of the ribbon and the slide can be expeditiously and economically affected. The ribbon end is first passed edgewise into the slot 8, then edgewise into the slot 1, or vice versa. Another portion of the ribbon is then passed edgewise into the slot l2 and then into the slot l3. This completes the assembly of the ribbon with the slide. 1

The sides of the slide which extend across the closed ends of the slots I and 8 are desirably provided with pressed reinforcing ribs 1a to stiii'en the slide in its weakest and most flexible portions.

The intermediate portion of the ribbon may be assembled with the loop 4 in. a similar manner. Each of the slots 3 and 6 of the loop is provided with an obliquely extending passage 20 enabling the ribbon to be slid edgewise into the slot from the periphery of the. loop; The ribbon may.

if desired, be fully assembled with the slide and thereafter assembled with the loop since it is not i necessary to have a free end of the ribbon for threading through the loop. The other length of ribbon 2 is inserted edgewise into the unoccupied slot oi. the loop I. This operation may also be effected after the ends of the ribbon 2 have been:

but a single length of ribbon but also becausea ribbon can be passed edgewise into a slot so narrow that threading through of the ribbon would slot and an oblique passage portion 23 is provided for guiding the ribbon into the slot.

It is desirable inthis form of construction to safeguard the ribbon against possible escape from the slots Ho and l3a through the passages 2| when adjustment is being made. To .this end each of said'slots is made a little wider at the end remote from the entrance passage than at the end adjacent such passage, the inner wall of each slot diverging slightly from the outer wall thereof as it recedes from the entrance passage.

Thus each inner slot wall is inclined slightly and has a slight tendency to shift the ribbon away from the entrance passage when the ribbon is drawn through the slot in either direction.

The loop of Figure! diii'ers from the loop of Figure 6 in the same manner that the slide of Figure 5 differs from the slide of Figure 4. Each slot 3a and 6a is entered from its end through a passage 24. A shoulder extends-completely across the normal width of the slot and an oblique passage portion 26 serves to permit the ribbon 5 to enter the slot.

While the forms of slides ,and loops illustrated herein have been described and shown as incorporated in shoulder straps for garments, it will be appreciated that their utility is not confined to such use. These elements may find utility in belts, garters, suspenders, and other articles of wearing apparel. The loops illustrated have utility as slides and reference in the appended claims to slides is intended broadly to apply to any of the 7 structures of Figures 4 to '7 unless inconsistent with the context.

While we have illustrated and described in detail certain preferred forms of our invention, it

is to be understood that changes may be made,

therein and the invention embodied in other structures. We do not, therefore, desire to limit ourselves to the specific constructions illustrated,

but intend to cover our invention broadly in whatever form its principle may be utilized.
