a blaims. (24-430) The inventionrelates to "clasps and especially to clasps for holding flexible connectors.
Objects of the invention areto provide'for effectively gripping andholding a cord, rope, cable or other flexible connectorin adjusted positions; to provide for so holding the cord by a wedging action along a slot while facilitating the quickrelease of the cord; and to provide a simple, inexpensive clasp which may be made by a molding operation and which is also practical and efiective for the intended purposes.
In the accompanying drawings, which form a part of this specification and in which like numerals-are employed to" designate like parts throughoutthe same,
Fig. l is a front view ofa claspadjustably holdmg the bight of a cord and constructed accordmg to andembodying the invention,
Fig. 2 is a sectional view taken along line 22 of Fig. 1,
Fig. 3 is a side view of the clasp shown in Fi 1,
Fig. 4 is a sectional view taken along line 4-4 of Fig. 3, parts being broken away, and
Fig. 5 is a sectional View taken along line 5--5 of Fig. 4, parts being broken away.
In the illustrative embodiment of the invention shown in the drawings, a clasp Ill includes a I body H having a longitudinal uniform passage or bore I2 through which reaches of cord in side-by-side relation or a bight I3 of a cord l4 extend in close and sliding relation therewith continuously along such bore. The body ll may be of plastic, hard rubber, metal such as aluminum alloy or other suitable relatively hard material as compared to the cord 14 and which material is desirably moldable for economical manufacturing purposes. The body ll of disk-like form having substantially parallel flat front and rear faces is and I6, includes a rounded portion I1 and a tapered end portion l 8 extending therefrom to the other end at H) of such body as viewed from the front; although other suitable body forms may be provided, if desired, such for example, as cylindrical, spherical, tear-drop, and oblate.
The bore l2 at the rounded portion I1 is intersected by a wedge or V-shape slot 2|] intermediate the front and rear faces !5 and I6 and extending substantially across the width of the body between the rounded sides Ila and [1b thereof. The retaining walls of the slot converge inwardly from the outer surface of the body to the bottom a of the slot while its center lies along a median plane which coincides 2 l with the center-line of the bore 1-2, as shown especially in Fig. 3. Such retaining walls at the bottom of the slot desirably slope from the sides of the body toward one another in the direction of the other end at H! of. the body ll and converge at a central position in'the body, as shown especially in Figs. 1 and 4, for. avoiding right angle bends in the cord M for the en.- gaged condition to relieve strain on the bent cord, also for facilitating engagement of such walls. with the cord by wedgingaction .s-ubstane 'ti'al'ly alongthe extent of: the. bottom of the slot to, assure firmly holding the. cord at'its end portions 2;! and 22. The retaining walls at the bottom of the slot 20. may be ridged or serrated-,. as shown especially in Figs. 4 and5, or knurled or otherwise. roughened. ,for fat-.i litating an engage ing action with-the. material of the cord to fur- .ther assure positively gripping the cord in the slot 12 for adjusted positions of the clasp.
The front and rear faces l5 and I6 of the body have, desirably, knurled or roughened depressions 23 and 24 therein at the region of the rounded portion I! for facilitating firmly grasping the clasp l0 between the fingers during manipulation of the clasp. If desired, the sidesof the ta pered end portion l8 may be transversely rounded toward the end I9 of the body I l.
After the cord M has been inserted through the bore 12 of the clasp ID in a manner to provide the bight I3 and the end portions 2| and 22 of the cord extending axially of the bore beyond the respective ends of such clasp, the latter may be grasped conveniently between the fingers of one hand of the operator at the knurled depressions 23 and 24 and moved slidingly along the cord to the desired position of adjustment.
With the bight in a tautened condition, the respective end portions 2| and 22 of the cord are bent and disposed in the slot 20 at opposite sides of the bore 12 providing a binding action at the juncture of the bore with the slot, and such end portions are positioned along the bottom of the converging retaining walls of such slot. The end portions are held securely between such walls at the serrated regions of the latter by substantial continuity of wedging and engaging actions at such regions. The separated end portions of the cord are released from the engaged condition by pulling on such end portions in the direction away from the bottom of the slot 20 and toward the center of the bore I2 thereby moving the end portions of the cord to the outer end of the slot axially of the bore thus facilitating sliding movetially across the width of said body between the sides thereof, said body having a uniform bore therethrough in communication with the bottom of said slot at a central position in said body, said bore being dimensioned for receiving a bight of the cord with cord reaches thereof disposed through said bore in side-by-side close relation therein and into said slot, the bottom of said slot diverging from said bore to said sides of the body and the front and rear walls of said slot diverging from said bottomto the outer surface of said body, said slot being dimensioned for receiving said cord continuously from said bore into said slot and for detachably holding portions of the cord by wedging" action in said slot against said front and rear .Walls and substantially continuously along the bottom thereof, the walls of said slot having spaced-apart ridges transversely of said slot for engaging the material of said cord.
' 2. A cord clasp comprising a body having a cord passage extending into the same to the central region thereof for receiving the cord in close relation continuously along said passage and said passage terminating in a slot in said body, said slot comprising a bottom wall extending from said passage to aside of said body, a second bottom wall extending from said passage to a second side of the body, and walls extending fromone said side to the other said side and converging inwardly 4 from the outer surface of said body to said bottom walls, said walls having engaging surfaces at the bottom of the slot for detachably holding said cord by wedging action against said engaging sur-- faces continuously along said bottom from said passage to said sides of the body.
3. A cord clasp comprising a generally fiat body having front and rear faces and a uniform bore centrally therethrough intermediate said faces and the sides of said body for receiving a bight of the cord with cord reaches thereof disposed through said bore in side-by-side close relation therein, and said body including a wedge slot extending laterally of said bore to both sides thereof and having front and rear walls between said faces extending substantially across the width of the body from side to side thereof and intersecting said bore at a central position in said body, said front and rear walls converging inwardly from the sides of said body to said bore providing a bottom of the slot having engaging surfaces at said bottom of roughened form for detachably holding portions of the cord by wedging action in said slot against'said surfaces continuously along said bottom from said bore to said sides of the body.
