Definitions

  • the invention pertains to a snap fastener for articles of clothing, for example, or for bags, tents, etc., of the type indicated in the introductory clause of claim 1.
  • This fastener comprises the snap fastener parts required for the desired snap-together effect, which have complementary male and female locking surfaces and which are therefore to be called “male part” and “female part” here.
  • the special aspect of this snap fastener is that the parts of the snap fastener are attached by means of a connecting part either to one and the same support layer or to two different support layers.
  • a snap fastener part which is connected indirectly by way of the connecting part to its support layer can be shifted in position with respect to its support layer. When the male part and the female part are snapped together, the associated support layers are connected to each other, but their positions can still be adjusted.
  • An adjustable snap fastener is known from U.S. Pat. No. 1,537,810.
  • the male part is connected to its support layer by a connecting part.
  • This connecting part consists of a base plate, which has been bent into a complicated shape, in which holes are provided to accept the pin-like end of the male part.
  • the male part itself consists of a bent piece of sheet metal, which has an opening, into which a pressure piece projects. This pressure piece is supported in the male part in such a way that its lower, thinner end can protrude through a lower opening in the male part and be received in one of the holes in the base plate.
  • this adjustable snap fastener Before this adjustable snap fastener is closed, that is, before the male and female parts are snapped together, the male part slides freely in the guide of the connecting part. Arresting the male part in the connecting part can be achieved only by snapping the parts of the snap fastener together, which involves the formation of a positive, form-locking connection between the pressure piece of the male part and one of the holes in the connecting part. The only way to change the position of the snap fastener is to release the fastener first. Each time the fastener is opened, however, the male part moves inside the connecting part, which means that its original position is lost and that the hew, desired fastener position can be found only by trial and error. Another disadvantage of this adjustable snap fastener is that it consists of a large number of parts, which are expensive to produce. In addition, the functionality of this known fastener is easily impaired in daily use by dirt or laundering, etc.
  • Another snap fastener is known from German Patent No. 650 156.
  • the female part has several receptacles for a male part. These receptacles in the female part consist of holes arranged lengthwise in a row, which cooperate with the male part.
  • the snap fastener is adjusted by selecting the appropriate hole in the female part.
  • the connecting part is eliminated, because the elongated shape of the female part takes over this function.
  • the disadvantage of this snap fastener is that only a special male part can work together with the female part and that the female part must be bent and stamped, which entails a complicated fabrication process.
  • the invention is based on the task of developing a simple and reliable snap fastener of the type indicated in the introductory clause of claim 1, which can be produced easily and cheaply, and the position of which can be adjusted relative to the support layer. This is accomplished according to the invention by the measures cited in the characterizing clause of claim 1, to which the following special meaning attaches:
  • the connecting element which serves to attach a male or female part to a support layer can adapt itself to the deformation of this support layer.
  • the connecting part consists of a flexible material.
  • the snap fastener according to the invention can also be used for jackets, pants, etc. This is important precisely in the area of the sleeve or leg seam, because here the support layer must bend around curves with small radii.
  • complementary latching means are provided in the connecting part and in an associated snap fastener part to allow the snap fastener to be positioned permanently and securely on the connecting part. When the snap fastener is opened, therefore, this snap fastener part is prevented from shifting position with respect to the connecting part.
  • FIG. 1 a shows a perspective view of the female part of a snap fastener attached to a support layer
  • FIG. 1 b shows a perspective view similar to that of FIG. 1 a of the male part of a snap fastener, which has been attached indirectly by a connecting part to a support layer;
  • FIG. 2 shows a top view of the connecting part with the male part of FIG. 1 b;
  • FIG. 3 a shows a cross section along line IIIa-IIIa of FIG. 2, crosswise to the connecting part, with the snapped-on male part;
  • FIG. 3 b shows a cross section along line IIIb-IIIb of FIG. 2, lengthwise through the connecting part, with the snapped-on female part as shown in FIG. 3 a;
  • FIG. 4 shows a side view of the male part of the previous figures
  • FIG. 5 a shows a top view of a pre-bent connecting part according to another exemplary embodiment of the snap fastener
  • FIG. 5 b shows a cross section along line Vb-Vb of FIG. 5 a, crosswise to the longitudinal axis of the connecting part;
  • FIG. 5 c shows a cross section along line Vc-Vc of FIG. 5 a through the longitudinal axis of the connecting part.
  • the adjustable snap fastener 10 has at least two complementary snap fastener parts, namely, a male part 11 and a female part 12 .
  • the two complementary snap fastener parts 11 , 12 are snapped together to produce a connection.
  • the support layer 19 to which the male part 11 is attached can be laid on top of a different support layer or another area of the same support layer 20 , to which the female part 12 is attached. So that the position of the snap fastener 10 can be adjusted, at least one of the fastener parts 11 , 12 is connected indirectly to its support layer 19 , 20 by a connecting part 21 .
  • FIG. 1 b shows an indirectly attached male part 11 .
  • the male part 11 is supported on the connecting part 21 by a closed guide, in which the male part is free to move. As a result, its position relative to the support layer 19 can be adjusted.
  • the connection of the male part 11 to the female part 12 also means that the support layers 19 , 20 are joined in such a way that their positions can be adjusted relative to each other. This is illustrated in FIGS. 3 a and 3 b, where the state in which the two snap fastener parts 11 , 12 are snapped together is also to be referred to below as the closed snap fastener 10 .
  • the connecting part 21 consists of a flexible material, so that it can easily adapt to a deformation of the support layer 19 , 20 .
  • complementary latching means are provided in the connecting part 21 and in an indirectly attached snap fastener part 11 , 12 to allow the corresponding snap fastener part 11 , 12 to be secured permanently in position on the connecting part 21 .
  • This permanently secure positioning guarantees at all times that the indirectly attached snap fastener part 11 , 12 is held in its position on the connecting part 21 both in the open and in the closed state of the snap fastener 10 .
  • the position of the snap fastener 10 can therefore be shifted only by using force (intentionally) to disconnect the latching means or by otherwise releasing them.
  • the adjustability of the snap fastener 10 depends essentially on the design of the complementary latching means, which will be described in greater detail in the following.
  • the connecting part 21 is assembled with the snap fastener part 11 to form a closed, straight guide device.
  • the closed guide device can have any other guide configuration, possibly even a circular one.
  • one component of the closed guide device consists of a continuous, elongated slot 22 in the connecting part 21 .
  • the other component of the closed guide device is formed by a taper 16 between a lower and an upper flange 14 , 15 of the snap fastener part 11 , 12 , as illustrated in FIG.
  • the snap fastener part 11 , 12 can have only one flange in the middle, and the connecting part 21 can have upper and lower convexities, which project into the slot 22 and which positively retain the flange of the snap fastener part 11 , 12 .
  • the snap fastener part 11 , 12 could also enclose the connecting part 21 in a U-shaped or ring-shaped manner and have the ability to slide along it.
  • the connecting part 21 would have to be designed in the form of a rail.
  • a connecting part 21 designed in this way would be joined to the support layer 19 , 20 by connecting seams, for example, extending down its long sides.
  • Recesses 23 are provided in the connecting part 21 to accommodate the lower flange 14 shown in FIG. 4, so that the lower flange 14 does not project out from the connecting part 21 toward-the support layer 19 .
  • the cooperation between the recess 23 in the connecting part 21 and the lower flange 14 of a snap part 11 can be seen in FIGS. 3 a and 3 b.
  • Recesses 23 can also be provided on the visible side of the connecting part 21 for the upper flange 15 of the snap fastener part 11 .
  • the previously mentioned complementary latching means have the task of permanently securing the position of the attached snap fastener part 11 , 12 to the connecting part 21 . This prevents any independent, unwanted sliding or shifting of the attached snap fastener part 11 , 12 .
  • the two parts of the latching means can work with each other in either a positive or nonpositive manner.
  • the positive positioning of the snap fastener part 11 , 12 on the connecting part 21 which is present when positively interacting latching means are used has the advantage that the snap fastener part 11 , 12 can never shift independently on the connecting part 21 .
  • the snap fastener 10 can be shifted only by intentionally forcing or releasing the positive connection between the latching means.
  • the snap fastener 10 can be adjusted by pulling forcefully on the indirectly attached snap fastener part 11 , 12 .
  • the positive connection between the complementary latching means can be overcome only by a strong tensile force, which causes a reversible deformation of the latching means of the flexible connecting part 21 .
  • the position of the snap fastener part 11 , 12 can be easily changed simply by the direct application of force.
  • the complementary parts of the latching means are designed to work together in such a way that the snap fastener part 11 , 12 is unable to move independently. This can be achieved, for example, by making sure that the positioning force (clamping force) in effect as a result of the nonpositive latching means is significantly greater than any tensile force which could act unintentionally on the latching means.
  • the latching means of the connecting part 21 consist of a series of recesses 24 in the slot 22 , which work together with the taper 16 between the upper and lower flanges 14 , 15 in the male part 11 ; this is shown in FIGS. 1 b, 3 a, and 3 b.
  • the female part 12 could also be connected indirectly by way of a connecting part 21 with freedom of adjustment to a support layer 20 .
  • an additional taper can be provided between the upper part 17 and the lower part 18 of the female part 12 to cooperate with the recesses 24 in the slot 22 of the connecting part 21 .
  • the latching means could consist of projections in the slot 22 of the connecting part 21 , which cooperate with concavities in the taper 16 in the male or female part 11 , 12 . This feature is not shown in the figures, but it certainly represents a usable alternative to the exemplary embodiments shown.
  • the latching means mentioned can also consist of a disconnectable arresting device, so that the male or female part 11 , 12 can be held in place on and released from the connecting part 21 .
  • the position of the attached snap fastener part 11 , 12 on the connecting part 21 could then be adjusted only after first releasing this arresting device. This therefore ensures that the snap fastener part 11 , 12 is held with absolute reliability on its connecting part 21 and thus on the support layer 19 , 20 , although it is still possible for the snap fastener part 11 , 12 to be moved to other positions on the support layer 19 , 20 , if desired.
  • the upper flange 15 of the male part 11 to be supported elastically with respect to its lower flange 14 , so that the distance between them could change.
  • the complementary part of the latching means it would be necessary to deepen the recesses in the visible side of the connecting part 21 provided for the upper flange 15 at the places where a stationary, positive positioning of the snap fastener part 11 is desired.
  • By simply pulling on the head 13 of the snap fastener part 11 therefore, it would be possible to release the positive connection and to adjust the snap fastener part 11 by sliding it to a different fixed position.
  • the connecting element 21 can be attached to a support layer 19 , 20 (e.g., by sewing), areas 25 of thinner material are provided, for example, along the outer edges. These thinner areas 25 make it easier to attach the connecting part 21 . It is also conceivable that the flexibility of the connecting part 21 could also be improved by providing thinner areas 25 .
  • the thinner areas 25 could be provided in the form of, for example, ribs, arranged transversely to the desired bending direction of the connecting part 21 .
  • connection part 21 it is advantageous for the connecting part 21 to be attached to the support layer 19 , 20 by sewing, by the use of an adhesive, by welding, or by some other suitable joining method. Of course, combination of individual joining methods are also possible. The joining method to be selected will depend on the purpose of the snap fastener 10 . For example, in the case of raincoats or tents, which must be water-tight, it would be especially suitable for the connecting part 21 to be welded tightly to its support layer 19 . In contrast, it would be conceivable in the case of luggage for the connecting part 21 to be sewed down tight or riveted to the support layer 19 , 20 in question for the sake of visual appearance.
  • the connecting part 21 consist of a bent shape.
  • a connecting part 21 of this type is shown in FIGS. 5 a - 5 c.
  • This pre-bent shape is especially suitable for sleeve and leg seams.
  • the curvature shown in FIG. 5 c can, of course, also assume a steeper angle.
  • the curvature does not have to be in the form of an arc; instead, it can also be S-shaped or take some other form.
  • the connecting part 21 there is no need for the connecting part 21 to be highly flexible.
  • the snap fastener 10 for the invention, furthermore, it is also possible to use a conventional female or male part 12 , 11 for the complementary snap fastener part 11 , 12 , which is attached indirectly by way of the connecting part 21 to its support layer 20 , 19 .
  • the conventional female or male part 12 , 11 could be mass-produced, as a result of which production costs could be reduced even more. Only in the case that both the male and the female parts 11 , 12 are supported adjustably in indirect fashion by way of connecting parts 21 on their support layers 19 , 20 would it be necessary to use corresponding complementary snap fastener parts 12 , 11 in accordance with the invention.
  • both complementary snap fastener parts 11 , 12 can be attached indirectly by way of connecting parts 21 to their support layers 19 , 20 .
  • the connecting part 21 can be located either on the upper, visible side, or on the lower, invisible side of the support layer. The decision depends, of course, on the concrete application of the snap fastener 10 .
  • the connecting part 21 As flexible material for the connecting part 21 , it is proposed that plastic be used. Through the appropriate choice of the plastic, the properties and the flexibility of the connecting part 21 can be essentially determined. It is also conceivable that the connecting part 21 could consist of a composite material, which combines various positive properties of the individual materials. In addition, it would certainly also be possible to use various metal alloys as the flexible material.
