A. SCHMID PIPE HANGER March 12, 1968 Filed Oct. 21, 1965 INVENTOR ARTHUR 5CHM/D BY Xwgq ATTORNEY 5 United States Patent 3,372,439 PIPE HANGER Arthur Schmid, Kreuzlingerstrasse/Grundweg 2, Romanshorn, Switzerland Filed Oct. 21, 1965, Ser. No. 499,339 4 Claims. (Cl. 24-21 ABSTRACT OF THE DISCLOSURE A pipe hanger including an embossed suspender band having recesses formed on one side thereof and corresponding projections on the other side thereof, the projections being shaped to engage in the recesses when the recessed side of the band is placed adjacent to the side thereof containing the projections, and a two-part connecting sleeve for securing two widths of the band together with the projections of one width of the band engaged in the recesses of the other width of the band, the two parts of the connecting sleeve forming a disengageable and detachable slider which in the disengaged state can be individually mounted on opposite sides of the two widths of the band and which can then be interlocked to hold the two widths of the band together.

Subject matter of the present invention is a pipe hanger.

The improvement is characterized in that the connecting sleeve comprises a plurality of composite parts defining a detachable slider and being so interconnected that in the detached state they may be individually applied to opposite sides of the carrier strap and then be interconnected.

One form of the invention is shown, by way of example, in the drawing, in which- FIG. 1 is a perspective view,

FIG. 2 shows a section through the connecting sleeve or slider respectively,

FIGS. 3 and 4 each show a side view of the slider parts detached from each other, partly in section,

FIG. 5 is a view of the springy slider part shown in FIG. 3,

FIG. 6 depicts the latter in direction of the arrow VI,

FIG. 7 shows the slider part of FIG. 5 in direction of the arrow VII in FIG. 5,

FIG. 8 illustrates the rigid slider part of FIG. 4 in elevation,

FIG. 9 shows the latter in direction of the arrow IX in FIG. 8, and

FIG. 10 shows the rigid slider part in direction of the arrow X in FIG. 8.

Referring to FIG. 1, the pipe hanger of this invention includes a suspender or carrier strap 1 having recesses formed in one side thereof and corresponding projections 2 on the other side thereof. The upper part 3 of the projections 2 are trimmed so as to engage within and interlock into the recesses on the other side of strap 1. To secure a pipe to a hanger bracket, the strap 1 is Wound around the pipe and the hanger bracket as shown in FIG. 1, with the projections of the strap portion 1' being engaged in the recesses of the strap portion 10, with the two strap portions being held together by a two-part connecting sleeve.

The connecting sleeve shown is a slider comprising two parts 11, 18 which form U-shaped clips or clamps and are interengaged with parallel legs. Slider part 11 forms a clip having springy flat legs 12 which on their external part toward the midpoint each form a tapered and shouldered locking leg 13. The two legs 13 have on their exterior flat side closure hooks 15 formed by recesses 14. The ends of the legs 13 comprise guiding faces 16 formed by the bevel of the exterior front edge. 17 denotes a part-leading space between two springy legs 12 for holding together the parts 1', 1" and 10 of strap 1. The slider part 18 is U-shaped in the form of a clip and comprises two rigid legs 19 which laterally engage the springy legs 12 of slider part 11. The rigid slider part 18 comprises two perforations or slots 20 extending along its legs 19 for the passage of the legs 13. These slots 20 on the two exterior fiat sides and within the range of the clip web are opened by recesses 21 so as to form connecting bridges 22 on the ends of the legs 19.

The locking legs 13 pass loosely through the slots 20 towards the guide space 17 and lie free in the recesses 21 with their stepped free ends 13. The leg end portions 13" project beyond the bases 21 of the recesses 21 and by their step at the point of transition to the recess, form closure hooks 15 which engage the bridges 22 from the rear. The ends of the legs 19 of the rigid slider part are provided inside of the center portion with beveled faces 23 for cocking the springy locking legs 13 on introducing same into the slots 20. The beveled counterfaces 16 of the locking legs 13 facilitate the introduction thereof into the slots 20. The guide space 17 situated between the two legs 19, together with the guide space 17 of slider part 11 forms the guiding space for holding together the parts 1', 1" and 10 of carrier strap 1.

When inserting the locking legs 13 of slider part 11 into the slots 20 of slider part 18, said legs are pressed towards each other according to the dot-and-dash lines shown in FIG. 2, against their spring action. Having reached the position of connection shown in FIG. 2, the legs 13 with their recesses 14 snap back away from each other and against the connecting bridges 22 and engage same from the rear through their locking hooks 15. In such interlocking position, the enlarged stepped leg end portions 13' project beyond the bases 21 of slider part 18. When it is desired to break the interlocking engagement of the two slider parts 11 and 18, part 18 in the range of its recesses 21 may be seized by a pair of pliers (not shown) to thereby urge inwardly the springy connecting legs 13 by the protruding cheeks 13' thereof, in the sense of the arrows a, down to the base 21. At this moment, the interlocking engagement has been lifted, and the two slider parts 11, 18 may be separated from each other.

Thanks to the two-part slider of which the parts 11, 18 are mountable on the strap portions from opposite sides over the edges of the carrier strap, as is shown in FIG. 1, relatively very short suspensions are possible.

In the present form of invention, the slider is mountable on the carrier strap also at points accessible with difficulty only. Vice versa, the release of the slider for quick removal from the carrier strap does not offer any difficulties.

While the invention has been described in detail with respect to a now preferred example and embodiment of the invention it will be understood by those skilled in the art after understanding the invention, that various changes and modifications may be made without departing from the spirit and scope of the invention and it is intended, therefore, to cover all such changes and modifications in the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A pipe hanger comprising in combination a suspender band having embossed engaging elements, and a disengageable and detachable connecting sleeve including a springy clip and a rigid clip, each said clip being U-shaped in cross-section thereby being positively laterally interengageable with each other and individually mountable on opposite sides of said band, said springy clip comprising spring legs having an engaging portion comprising recesses and closure hooks on two outwardly facing fiat sides of said spring legs and a locking leg portion, said rigid clip comprising rigid legs having openings to receive said locking leg portion and connecting bridges which fit into and rearwardly of said recesses and closure hooks, respectively.

2. A pipe hanger as claimed in claim 1 wherein said rigid clip includes slots on two outwardly facing fiat sides of said rigid legs extending in a direction parallel to said legs to receive said locking leg portion of said springy clip.

3. A pipe hanger as claimed in claim 1 wherein said rigid clip includes a guide means for guiding said locking leg portion into said openings as said clips are being positively laterally engaged.

4. A pipe hanger as claimed in claim 3 wherein said guide means includes inclined ramps on inside of said rigid legs along which said locking leg portion may be guided into said openings.
