Our present invention relates to a maternity brassiere closure or buckle of the type provided between a flap of a maternity brassiere to cover the breast when it is not in use for nursing, but releaseable to expose the breasts for nursing.
Nursery brassiere closures are known and widely used (see Design U.S. Pat. No. 369,327 issued 30 Apr. 1996 and Design U.S. Pat. No. 412,462 issued 3 Aug. 1999).
Basically, the hook portion of such a closure is connected on the one hand to a shoulder strap of the brassiere and on the other hand to the body of the brassiere which has an opening at the brassiere cup through which the breast can be exposed for nursing, the eyelet portion is engaged with the hook.
While such maternity brassiere closures are currently in use highly successively, it has been found that improvement in them is possible.
It is, therefore, a principal object of the invention to provide an improved maternity closure which is more reliable and more easily used than earlier closures and which can securely maintain a closed portion even if the fabric of the brassiere is brought into disarray.
It is another object of the invention to provide a maternity closure which is particularly smooth and safe, is less likely to cause injury to the nursing infant and is capable of generating a clear signal when the fastener is opened and closed.
These objects and others which will become apparent hereinafter are attained in accordance with the invention in a maternity brassiere closure comprising:
an injection-molded generally bilobate plastic hook element formed in one piece with an upper, downwardly concave slot adapted to receive a loop of a brassiere shoulder strap, a lower, upwardly concave slot connectable to a body of the brassiere and coplanar with the upper slot, a generally oval central member between the slots, a hook projecting perpendicularly to a plane of the slots and the central member and having an upwardly extending finger parallel to the plane and spaced from the central member, and an opening having generally the shape of the finger formed in the central member in alignment with the finger; and
an injection-molded plastic one-piece eyelet element of generally trapezoidal shape having a relatively short upper limb, a relatively long lower limb and a pair of lateral limbs inclined to the upper and lower limbs, an arcuate slot formed in the eyelet element along the lower limb and connectable to a breast-covering flap of the brassiere, a substantially rectangular window formed in the eyelet element below the upper limb whereby upon the upper limb engaging the hook, the hook is receivable in the window, and a generally rectangular tongue extending upwardly from a bottom of the window and resiliently deflectable by a base of the hook upon passage of the hook into the window.
According to a feature of the invention, the finger is rounded along all sides and the base of the hook is rounded as well to avoid any injury to the infant. The outer parameter of the hook element is likewise rounded throughout as is the trapezoidal perimeter of the eyelet element.
In another feature of this invention, the upper limb is of circular cross section and the lower limb is tapered away from the upper limb and is rounded both in cross section and along its lower perimeter.
The tongue of the eyelet element is advantageously formed as a thin portion of the eyelet located along a median plane thereof, the eyelet element being symmetrical to opposite sides of this plane.
In a further feature of the invention, the generally oval central member of the hook element can be offset slightly to the side of the median plane of that element to which the hook projects. The base of the hook is relatively thick, i.e. can have a thickness greater than that of the finger and of the central member.
The upper and lower limbs of the hook element, in turn, can be tapered away from one another and rounded in cross section. The result is a maternity brassiere closure which, because of the rounded base and tongue provides a point click indication of engagement/disengagement as well as a pedestal around the hook which is also rounded so as to minimize any danger to the infant. The rounded configuration of the oval central member and the perimeters of both the hook and the eyelet portion likewise insure safety of the infant. The two elements are advantageously injection molded of polyoxymethylene.
The above and other objects, features, and advantages will become more readily apparent from the following description, reference being made to the accompanying drawing in which:
In
The finger 19 lies parallel to the plane P and the oval portion 15 is offset slightly with respect to the plane P in the direction to which the hook projects, i.e. to the length in
The eyelet portion 30 is generally of trapezoidal configuration and has an upper limb 31 of circular cross section (
In addition, the corners 35 of the trapezoidal element 30 are rounded. A thin web 36 above the slot 33 is formed with a generally rectangular window 37 into which, from the bottom, extends a resiliently deflectable tongue 38. When the upper limb 31 is engaged over the hook 16 as shown in
