FASTENER Filed July 19, '1947 INENTOR. Geowg F. Dixon ATTORNEYS A particularly useful feature of the present fastener is the facility with which it may be attached without rope or straps to an upright post of an infants crib. Such a post is indicated at 4 and may be closed or inaccessible at both ends as by the top and bottom rails of the crib. Thus it becomes necessary to assemble the fastener on the post without passing the fastener over the end of the post. To place the frame I about the post 4 the slide clamp 2 is first disassembled or removed from the frame t' so that elongated cen-- tral opening l5 of the frame is clear. The frame l which is normally substantially fiat with its several parts disposed in a common plane is then sprung or twisted to the shape shown in Fig. 3'; in which the sides 8 and 9 are distorted from. their normal positions indicated by the broken lines to the curved positions indicated by the solid lines.

The sides 8 and 9, when so distorted, are disposed in divergent curved planes and the ends thereof carrying the lateral extensions Il and i2 are sufficiently far -apart to pass the' post li into the central aperture l5 of the clamp frame. After passing the post l past thel lateral extensions ll and l2 ofthe frame the latter, byl reason of its inherent resiliency, snaps itself or moves back to its normal flat position. Thereafter the slide or clamp 2 is assembled on the frame I in the manner previously described andthe fastener is ready for use.

To secure in the fastener apiece of fabric m-aterial such as the blanket 3 an end corner I6 of the blanket is first passed upwardly through the central opening l5 of the fastener behind the cross bar or clamp 2. The blanket corner is then drawn forwardly over the top of the cross bar 2 and passed downwardly between the cross. bar and the lateral extensions I'I and I2` of the frame, The portion of the blanket that is engaged between the bar 2 and the lateral extensions l l and i2 of the frame is tightly clamped in place, any force orv tug on the blanket' proper tends to draw the cross memberv 2 tightly against the lateral extensions Il and l2` more securely to pinch and retain the blanket portion there'- between.

As shown in Fig. 2 the plane of thel crossl bar or clasp 2 is at a right angle or substantial-ly normal to the plane of theA rectilinear frame I. parts of the fastener maintain themselves in this right angled or perpendicular relationship` by reason of the relatively close flt of the sides 8 and 9 in the elongated openings 6 of the slides As shown in Fig. 5 onlysliding clearance is provided between the frame and the sides of the openings or apertures 6 so. that'y twisting of the cross bar or clamp Y2 is minimized'.

Although the clearance between the slide bar or clamp and the side members of the frame is suiiiciently close to restrict the twisting of the clamp bar on the frame the clearances in the ends of the elongated aperturesb are sufficient. to pass the extensions Il and l2 bodily there.- through when the sides 8 and 9 are sprung apart permitting the extensions to clear the cross, meinber or bridge of the clamping bar.

The-principles of the present invention may be utilized in various ways, numerous modifications and alterations being contemplated, substitution of parts and changesv in construction being resorted to as desired, it being understood that the embodiment shown in the. drawings. and described above is given merely` for purposes of. explanation and illustration: without intending,

4. to limit the scope of the claims to the specific details disclosed.

What I claim is:

1. In a fastener of the frame and sliding clamp bar type in which the frame has spaced side members and cross members and the sliding bar assembled on the frame is apertured to receive the side members of the frame and is movable toward and away from one of the cross members of: the frame to clamp material' to:y be fastened therebetween, the improvement which comprises the combination of a cross element on the sliding clamp bar and a transverse slit severing said one cross member of the frame, the slit being so disposed as to pass the cross element of the clamp bar therethrough upon distortion of the frame, the undistorted frame normally holding the slit closed to retain the clamp bar assembled on the frame;

2. A fastener comprising a generally U-shaped frameV member having spaced leg portions and lateral extensions on the leg portions directed to.- vvard one another, theV lateral extensions` being I aligned and having confronting ends substantially in abutment, and a slide clamp having, spaced openings separated by a cross element.. the slide being receivable on the frame member upon. springing apart of the leg portions of the latter to pass the cross element between the confronting ends of the lateral extensions, the no1=- mal space between said confronting ends bein-gI less than the width of the cross element whereby engagement of the cross element and one or both-` of the lateral extensions retains the slide in assembled relationY on the U-shaped member.

3. A fastener comprising a resilient U-shaped frame member having spaced leg portions and lateral extensions on the ends of each leg portion, the. lateral extensions being directed toward, one another to substantially abut one another and normally substantially closing the end of the frame, and a slide clamp substantially of figurey 8 shape receivable on the U-shaped frame member, said slide clampv having elongated openings f for receiving the leg portions of the frame memi members each having a lateral extension at the split end, and a clamp slidably mounted onsaid frame side members, the frame being deformableto spread the side membersl and lateral extensions for removal of the clamp from and assembly of 'the cla-mp on the frame, said' clamp having twoy elongated apertures substantially in. end to end relation and a bridge intermediate said apertures, said elongated apertures of the clamp being shaped to pass the spread lateral extensions and frame side members, and said bridge being disposed to pass through the end split during such removal' and assembly.

5. A holding device comprising a resilient frame including spaced side members having lateral extensions directed toward one another andl a clamp slidable on the side members; the cla-mp having a pair of spaced apertures to receiver the side members and a stop element between. the apertures, said` stop element being disposed normally to engage at least one. of the. lateral einl tensions to retain the slide clamp assembled on the frame, the apertures being suii'iciently large to simultaneously pass the lateral extensions therethrough upon distorting the frame to move the lateral extensions relative to one another to permit passage of the element between the eX- tensions for disassembly and reassembly of the slide clamp and the frame, the frame in use be ing retained in normal shape by its inherent resiliency and being returned to normal by inherent resiliency upon release after said distortion.

6. A holding device comprising a resilient frame member having spaced side portions and inturned ends on the side portions directed toward one another and separated by a slit, and a, clamp member apertured to receive the side portions of the frame member and slidable along the latter when assembled with the frame member, the inturned ends of the frame member being disposed normally to engage the clamp member to retain it assembled on the frame member, the apertures in the clamp member being large enough to pass the inturned ends of the frame member and having a different spacing from that of the slit between the inturned ends to require slight deformation of the frame to pass the inturned ends through the apertures in assembly and disassembly of the members, the frame member being adapted, upon release, to return to normal by inherent resiliency.

7. A holding device comprising a resilient frame member having spaced side portions and inturned ends on the side portions directed toward one another, the side portions and ends of the frame member all being normally disposed in a common plane, and a clamp member apertured to receive the side portions of the frame member and slidable along the latter when assembled with the frame member, the inturned ends of the frame member being disposed normally to engage the clamp member to retain it assembled on the frame member, the apertures in the clamp member being large enough to pass the inturned ends of the frame member and being slightly displaced from the normal positions of the inturned ends to require slight deformation of the frame to pass the inturned ends through the apertures in assembly and disassembly of the members, the frame member being adapted, upon release, to return to normal by inherent resiliency.

8. A holding device comprising a frame member of resilient plastic composition having spaced integral side portions and integral inturned ends on the side portions directed toward one another, and a clamp member also of plastic composition apertured to receive the side portions of the frame member and slidable along the latter when assembled with the frame member, the inturned ends of the frame member being disposed normally to engage the clamp member to retain it assembled on the frame member, the apertures in the clamp member being large enough to pass the inturned ends of the frame member and being slightly displaced from the normal positions of the inturned ends to require slight deformation of the frame to pass the inturned ends through the apertures in assembly and disassembly of the members, the frame member being adapted, upon release, to return to normal by inherent resiliency 9. A fastener comprising a resilient frame having spaced side members formed at one end of the frame with lateral extensions directed toward one another, a clamp member formed with spaced apertures to receive the side members or the frame, said clamp member apertures being substantially of the same general shape as and large enough simultaneously to pass the lateral extensions of the side members and being at a diierent spacing from the normal spacing of the lateral extensions of the frame to require slight deformation of the frame from normal to pass the lateral extensions thereof through said apertures in assembly, the frame returning to normal by inherent resiliency from said slight deformation whereby the different spacing of the apertures with respect to the normal lateral extensions retans the clamp member assembled on the frame.
