26 Claims.

This invention relates to a flexible beading strip, and, more particularly, to a strip having a resilient flexible cover intimately formed thereon.

Beading stripshave long been used- 'for applying finishing edges to upholstered articles, as sealing strips for closing the joint between two.v

' coverings disposed about the bead and secured in place thereon. If it was desired in these` prior constructions to fit the beading about a curve` having a short radius of curvature, `it was practically impossible to get a smooth finished appearance, due to the fact that the material on the inside of the curve would'bunch and the material on the outside'of the curve would approach its limit of stretching and prevent the bead from being properly curved.

Further, when the bead is to be used as a weather stripping, or a, seal, and subject to adverse conditions, the cover must, of course, be of such material as will protect the bead from deterioration.

An object of the present invention is to provide a beading strip which has an attractive appearance and is satisfactory for the purpose of sealing or ornamenting upholstered articles, and at the same time thebeading strip, with its desired covering thereon, may be readily bent to the desired curvature. Afurther object of the present invention is the use of av cover of such material as to .protect and :prevent deterioration of the bead when used in locations Awhere the bead is subjected to adverse conditions.

These objects are accomplished, according to the present invention, by providing the core or bead portion of the beading strip of flexible material and securing thereto an anchoring strip of flexible material and.` then covering the bead and anchoring-strip with a'exible resilient coating intimately secured thereto so as to become integral therewith to bend and flex with the bead, which covering material not only protects the bead but also provides it with a suitable outward appearance that blends with the material with which it is to be used.

When the beads and attaching strips have been secured. together, they are covered with the elastic coating which nrrnly adheres to the surface of the bead and attaching strip so as to com- 1 pletely cover the same. .This covering material will enable the bead and attaching strip to be ntted to a curve having a relatively short radius of' curvature as it will yield, when the bead is applied to the curve, by stretching onthe outside of the curve and compressing on the inside of the curve, thus presenting a smooth outward appearance. In the preferred form of the invention,A the iiexible resilient material forming the cover can be deposited from a latex dispersion, synthetic latex, synthetic rubber, or any material'of this nature and can be self-curing, air-cured, or heatcured. l

Further, the covering material can be provided with any suitable pigment, coloring matel rial or filler so as to produce a surface which will blend with the upholstery orlike material with which it is to be used. Also, the covering material can be provided with suitable materials which will resist deterioration of the seal in case the .bead is to be used under adverse conditions, since it completely encloses the bead and attaching strip. and seals it against contact with injurious elements. l l

The covering material may be applied to the assembled bead or attaching strips in many ways, as, for example, by dipping, spraying or otherwise applying the coating so as to completely cover the surface. Y

With a covering of this nature, various materials can be used forv the bead and attaching strirp. Rubber, sponge rubber, cotton bats, paper or fibrous cord, or the like material can be used for the' bead, and stiff fabric such as crinoline or buckram, a laminated strip of wire loops positioned between cheesecloth, paper or fabric, and wire screen or the like material can be used for the attaching strip,L since they will be adequately protected by the cover and will not present an objectionable appearance in use.v

The bead, according to the present invention. can be of various sizes and shapes and can be located in various positions with respect to the attaching strip. In some cases, the bead can be omitted entirely and the stii resilient attaching strip covered with a layer of latex deposited from a dispersion of latex or the like covering material and used in such a manner as to form a sealing or reinforcing member.

Other features and advantages will'be apparent from the specification and claims when cousidered in connection with the drawings, in which:

. Fig. l5 shows another form of the invention in at 20c in Fig. 10; or it can be elliptical in crosssection, as shown at 29d in Fig. 1l.

The bead can be formed of various 'materials which are flexible and capable of bending and also are resilient enough to form aseal if used for that purpose.

Preferably, the bead 20a is made of solid rubber, sponge rubber, or the like, as illustrated in-Figs; 1 to 11, 13, 14 and 19, and can be molded directly on the attaching strip, can be formed in two halves andcemented together, or can be formed in a solid piece with a slit therein for receiving the attaching strip.

If desired, the bead can be formed as a hollow rubber member 20e which can be two separate hollow members secured together or can be extruded as a single member and folded into circular formation as shown in Figs. 15 and 16. In extrudingthe bead, it can be formed with its surface, which is shown engaging the attaching strip, in a straight line, or itmay be extruded in such a manner that there is a tendency for these sur- -in Fig. 18.

The beads are mounted and held in proper position by attaching strips. These strips are of which the bead is formed by a hollow rubber member. Fig. 16 is a side elevational view, partly in section, of the form of the invention shown in Fig. 15. Fig. 17 is a perspective view of another form of the invention in which the bead comprises cotton bats.

Fig. 18 is a perspective view of another form of the -invention in which the bead comprises paper or iibrous cord.

Fig. 19 is a perspective view of a form of the stiff bendable material having suiiicient resili- The attaching strip may take many forms, as

shown in the drawings. It may comprise a reinforced laminated strip including a plurality of loops of wire 25 disposed vbetween layers of cheese-cloth 26, as shown in Figs. 1, 2, 7 to 11, 15

' and 16, or disposed between layers of paper 28a invention wherein the bead portion alone is covattaching strip covered and completelyenclosed by a relatively thin coating or film 22 of flexible material.

As shown in the drawings, the bead 20 can be of any desired shape, for example,"it can be circular in cross-section, as shown. at 20a, 20e, 2M and 20g in Figs. 1 through 8 and 13 through 19; it can be oi an irregular shape, as shown at 2Gb in Fig. 9, wherein the sides of the bead are symmetrically disposed about the vertical axis; it can or other fabric, as shown in Figs. 5 and 6, with the ends of the wires formingloops 21 projecting beyond one edge of the cheesecloth or other material which is to be secured inthe bead.

The laminated strip is secured in the bead by having the edge thereof disposed within the bead with the material of the bead extending through the loops to interlock therewith, and the fabric firmly adhered to the material of the bead by cementor other adhesive material. The laminated strip is positioned with respect to the bead so as to extend. radially therefrom, or it can project at an angle to the axis of the bead, as shown in Figs. 10 andll.

The cheesecloth or other material of the laminated strip, which is used with the wire loops, can be suitably treated with a binder or rubber cement which will cause the rubber to,

adhere thereto so that the rubber of the bead or the cement used in securing the strip in place in the bead will firmly hold the laminated strip in the bead. y

'I'he attaching strip may also comprise .a strip of wire screening 28, as shown in Figs. 3, 4, 17 and 18. In this form of the' invention, the screening ispositioned so as to extend into the bead.

be semicircular so as to have a'ilat side, as shown 75 and the rubber or material on the bead is caused to adhere to the wire and through the apertures in the screen to securely anchor the strip to the bead. 'I'he wire screening may have the strands thereof of the same thickness, or the strands. which are perpendicular to the axis of the bead, may be heavier as the strip may require.

The attaching strip may also take the form of a. plurality of loops of wire 25 interwoven with fabric 29 as shown in Fig. 12, or it may comprise a stiff fabric 33 such as crinoline or buckram suitably treated and interlocked with the material of the bead. If the fabric is suciently roughened to obtain this interlock, no further operations are necessary on the fabric. However, if it is desiredvto obtain a more secure hold between the attaching strip and thebead, a plurality of openings 3| can be provided alongthe edge of the attaching strip which is positioned in the bead so that the material of the bead can be interlocked therewith.

In cases where the bead is not desired, it may be omitted as shown in Fig. 12 and the attaching strip utilized as a sealing or reinforcing member.

The beads, especially when made of rubber or articial rubber, according to the present invention, are preferably treated `or impregnated with a bonding material or other composition before they are covered with a thin coating or layer of resilient iiexible material which becomes intimately secured thereto so as to bend with the bead. If desired, the beads and attaching strips can also be impregnated with the bonding material prior to the application of the cover so that it more readily adheres thereto.

In the preferred form of the invention,`the covering materialy comprises a deposit from a dispersion of latex, and the thin coating or layer thereof can-be formed by dipping, spraying or otherwise applying the latex -to the treated bead and attaching strip so as to completely enclose and encase the same. The cover when so made will completely seal the bead and attaching strip against engagement by foreign materials and will enable the various types of bead and attaching strips'as noted above, to be used with satisfactory results. Other materials may be used for the 1 cover, such as synthetic latex, rubber, synthetic rubber, or the like resilient flexible materials, and the cover materials can be self-curing, air-cured, or heat-cured.

Suitable pigments, coloring material or fillers fabric 29. In this form of the invention, the coating of resilient material is placed only over the bead 20a, and the fabric of the attaching strip is dyed so as to have the same color as the surface of the bead. This form of the invention may be desirable where the attaching stripis to be covered by upholstery, and, therefore, will not be required to have'the covering or coating of elasticv material disposed thereover.

The beading strip can be attached in position by having its attaching strip provided with a dry adhesive or thermoplastic adhesive, which can be caused to adhere upon being rendered tacky or by heat and pressure or can be cemented in place. Also the beading strip can be attached by stitching, tacking'or otherwise fastening it to the frame or element to which it is to be secured, and the resiliency of the attaching strip will hold the bead in proper position.

It is to be understood that in the broader aspects of the inventionv the various types of beads can be used with the various types of attaching strips and be covered with. any one of the above covering materials suitable for the use to which the strips are to be applied.

Variations and lmodifications may be made Within the scope of this invention and portions of the improvements may be used without others.

I claim:
