1 Qlaim. 1

This invention relates to an improved form of mounting device for mounting cards, photographs, pictures and the like on a mounting sur-. face.

Heretofore mounting devices of this general character have been formed for. the most part with a gummed or other type of adhesive surface on one side only thereof, and that is on the underside of the pocket which receives the corner of the card. The purpose of the adhesive on this underside of the pocket is to enable the mounting device to be secured to a mounting surface. It has also been customary in the past to omit any adhesive or gummed surface on the inside of the pocket thereby resulting in easy removal of the card from the mounting devices which hold it.

This latter type of mounting device has dis-. advantages in that the card may easily fall out of the mounting device and there is no way in which to mount the card permanently without the application of an adhesive directly to the corner of the card. There have been attempts to produce a, mounting'device which may be folded from a blank in such a way that, although the blank is gummed on one side only, gummed surfaces may be presented both on the under and top sides of the pocket. This form of mounting device has the advantage of being able to be secured to. a mounting surface and at the same time securing the corner of a card in a pocket by merely moistening the gummed inner surface of the pocket. The blank from which such a mounting device must be formed, however, necessitates a complicated stamping action in the manufacture thereof, and thus was found to be expensive to produce.

The principal object of the present invention, therefore, is to provide a mounting device for cards and the like which may be easily and eco, nomically manufactured.

Another object of the invention is to provide a mounting device which may be producedin elongated continuous strip of material and there;- after cut into predetermined lengths to form a body portion capable, of being folded to form a pocket.

A further object of the invention is to provide a mounting device formed of a single strip of material having an adhesive applied to both sides I thereof.

Still another object of the invention is to provide a mounting device which includes a body portion formed of a single strip of material and ayi -gamma or other type of adhesive surface on both sides thereof, and wherein a substantially triangular member is applied intermediate the ends of the body on one side there; of thereby to provide a pocket between the, mem ber and the body. 7

A still further object of the invention is to provide a mounting device which includes a body portion formed of a single strip of material hav; ing an adhesive or gummed surface on both sides thereof wherein a substantially triangular shaped member is applied to one of the gummed surfaces intermediate the ends thereof to provide a pocket, and whereby the final device may be formed by folding the ends of the body along the sides) of the triangular member, whereupon the ends li e in overlapping relation and may be secured together by means of the gummed or adhesive, sur faces thereon. f

Other objects and advantages of the invention will become apparentfrom reading the following description taken in conjunction with the accompanying drawing in which:

Fig. 1 is a plan view of a strip of material from which the present mounting device may be formed; v

Fig. 2 is an enlarged longitudinal sectional view through the strip of material taken along the plane ofline 22 of Fig. 1;

Fig. 3 is a plan view of a length of material cut from the stripshown in Figs. 1 and 2 and from which the mounting device is formed by iolding there being an ornamental triangular member shown attached to the body of Fig. 3;

Fig. 4 shows the body of Fig. 3 partly folded Fig. 5 is an enlarged plan view showing the strip in its final folded position to provide the finished mounting device of the invention;

Fig. 6 is a fragmentary perspective view showing one of-the mounting devices applied to a mounting surface; and t Fig. '7 is a section on the line 7-4 of Fig. 6 showing the device mounted on a sheet and securing a photo print in position. p

In accordance with the present invention the. manufacturing cost thereof may be sharply reducedbcause the individual body portion from which each mounting device is formed is cut from a continuous length of strip material such as shown in Figs. 1, 2 and 3. This strip. of ma terial is indicated generally by the numeral I and is provided along one edge. thereof with a plurality ofspaced inwardly extending. and sub-. stantially triangularly shaped notches 2.. The. opposite side of the strip is provided with a like. number of triangular notches 3 extending in-.. wardly. from the opposite edge of the. strip and. positioned so that the apices. of the notches .2 and 3 will be in substantially the same. transverse plane. The notches 3 are preferably.- slightlysmaller than the notches 2. The upper and lower surfaces of the strip are provided with an adhesive which is preferably a gummed surface as indicated at 4 and 5. The gummed surface has been found to be more satisfactory because it presents a dry surface which can be easily handled and requires only moistening to bring out the adhesive qualities thereof.

A triangularly shaped member 6 may then be placed on the upper surface of the strip material as shown in Fig. 3. A plurality of such members 6 are located in actual practice in spaced apart relation along the length of the continuous strip and are so located that the base of the triangular member 8 is parallel with and coincident to one edge of the strip. The apex of the member 6 is adapted to coincide with the apex of the corresponding notch 2 at the opposite edge of the strip. After the triangular members have been applied, the strip is severed transversely at a point intermediate adjacent members 6, whereupon a body gen erally indicated at l is provided. If desired, the base of the triangular member 9 may have a small triangular notch 8 in the base thereof to coincide with the triangular notch 3 over which the member 6 is placed. This notch is used primarily for decorative purposes.

The body I then has end portions 9 and it at opposite sides of the member 5. In forming the mounting device from the body or blank '1', one end If] is folded under the member 6 along one edge I I thereof, as illustrated in Fig. l. The next step is to then fold the end portion 9 under the member 6 along the edge l2 of said member. The notch 2 permits the ends ii and If! to lie in overlapping relation after they have been folded as shown in Fig. 5. The fact that both sides of the body or blank '5 are provided with gummed surfaces enables the two end portions 9 and H) to be secured together in overlapping relation.

It is immaterial which of the end portions 9 or H) is folded under first, but in the illustration of Fig. 4, the upper gummed surface of the end it will be facing downwardly after it has been folded and the under gumrned surface of the end 9 will be facing upwardly after that end has been folded. Moistem'ng the overlapping gurnniecl portions of these ends will then enable the ends to be fastened together as shown in Fig. 5 to complete the mounting device.

The pocket which is adapted to receive the corner of a card or other similar item is formed between the triangular member 6 and the over lapping folded ends 9 and iii. The ends 9 and H] are longer than the width of the body or blank 7 so that in their folded condition they provide a bottom wall of the pocket which is greater in length than the upper wall of the pocket formed by the member 6.

In actual use, the mounting device may be applied to a mounting surface such as shown at l3 by moistening the under side of the bottom wall of the pocket. The pocket may then receive the corner of a card or the like as indicated by the dot-dash lines 14 in Fig. 6. If it is desired to mount the card permanently, then the upper surface of the bottom wall of the pocket may be moistened, whereby to adhesively secure the corner of the card in place within the pocket. Customarily four such mounting devices will be utilized for the mounting of a card or other such item, one for the reception of each corner thereof.

The advantages of such a construction as disclosed and described herein are numerous. A principal advantage is the permanent security of mounting afforded by the device, due to the twosided gumrning of the blank from which the device is made. Once a photographic print or card has been properly mounted on a mounting sur-- face by means of the present device, it is practically impossible to remove such print or card therefrom, since the adhesive or gummed surfaces of the device adhere rigidly to both sides of the print or card and to the mounting surface. An additional advantage is that the device obviates the necessity of applying a paste or glue to the under side of the print or card to mount the same permanently on a mounting surface. Another advantage is that of economy of manufacture. This economical manufacture is the result of cutting the individual blanks from which the device is formed from a continuous strip of material. The device also has the additional advantage of being decorative and pleasing to the eye because the triangular member 6 may be embossed with any suitable design. Furthermore, this member 6 may be formed of paper, plastic, or any other suitable material and may also be formed of various colors.

Changes may be made in the form, construction and arrangement of parts from that disclosed herein without in any way departing from the spirit of the invention or sacrificing any of the attendant advantages thereof, provided, however, that such changes fall within the scope of the claim appended hereto.

The invention is hereby claimed as follows:

A mounting device of the character described, comprising a body formed of a single elongated strip of material having parallel edges, both sides of said strip being gummed, said strip having a triangular notch in one side thereof, the base of said notch being in alignment with said edge, a second triangular notch in the opposite edge of said strip having the base thereof in alignment with the second edge, the apices of said notches being in spaced aligned relation, a triangular member applied to one of the gummed surfaces of said body intermediate the ends thereof, the base of said triangular member being coincident with the second-mentioned edge of said strip, the apices of said first-mentioned notch and said triangular member coinciding and the converging sides of said triangular member being in alignment with the sides of said first-mentioned notch, the ends of said material being folded under said triangular member along the sides thereof and secured together in overlapping relation by the gummed surfaces thereof, thereby forming a pocket, the gummed undersurface of which is adapted to be secured to a mounting surface and the gummed inner surface of which is adapted to secure the corner of a card or pic ture received in said pocket.
