WAISTBELT BUCKLE

Abstract

 Problem
In sufferers of overweight or pelvic tilt, the waist is slanted forward, its front portion thus pointing slightly downward. When an individual affected by either of these conditions wears a belt, the top of the belt thus pushes forward with the tilt and the front of the belt and buckle tend to face down, impairing its esthetic appeal to onlookers.
Solution
Waistbelt buckle, preferably of metal or silicone,
characterized in that,
in cross section, the buckle forms a wedge (10).

Description

Technical Field

[0001] The invention pertains to the products as per the first portion of the independent claims.

Background Art

[0002] A clasp or buckle is any device used for fastening two loose ends, with one end attached to it and the other held by a catch in a secure but adjustable manner.

[0003] PTL1 discloses a belt buckle having a wing-shaped front.

Summary of invention

[0004] The invention as claimed is hereinafter disclosed in such a way that the technical problem with which it deals can be appreciated and the solution can be understood.

Technical Problem

[0005] In sufferers of overweight or pelvic tilt, the waist is slanted forward, its front portion thus pointing slightly downward. When an individual affected by either of these conditions wears a belt, the top of the belt thus pushes forward with the tilt and the front of the belt and buckle tend to face down, impairing its esthetic appeal to onlookers.

[0006] While this outcome may in some cases be counteracted by tightening the belt, such practice adversely affects the wearer's health (cf. NPL1).

Solution to Problem

[0007] The problem is solved as per the second portion of Claim 1.

Advantageous effect of invention

[0008] A buckle as per the invention is adapted to rotund wearers, its wedge shape preventing the buckle's front from tilting forward. With his or her buckle standing upright and clearly visible, the wearer appears slimmer to the casual observer.

[0009] For mechanical support of the strap, different options bear specific advantages. In an embodiment as per Claim 3 - hereinafter referred to as "closed guidance" - the frame remains fully visible, lending the buckle an atypical yet harmonic appearance while eliminating the requirement for an additional loop. The alternative as per Claim 8 - hereinafter referred to as "open guidance" - accommodates belt straps of arbitrary thickness in a comparatively flat buckle.

Brief description of drawings

[0010] 

Figure 1 illustrates the wedge shape of the buckle.

Figure 2 and Figure 3 show embodiments with open guidance.

Figure 4, Figure 5, and Figure 6 show embodiments with closed guidance.

Figure 7 illustrates the fixing of the belt with a tongue.

Figure 8 illustrates the fixing of the belt with a prong.

Description of embodiments

[0011] Figure 1 depicts a wedge (10) whose base (11), when in use, would face the wearer's lower abdomen. Correspondingly, the vertical strap guide (12), which would face away from the wearer's body, slopes away from the base (11) such as to maximize inclination while minimizing depth between the base (11) and front face. The latter's corners may be equipped with pins engaging with mating bores of the wedge (10) to allow for easy swapping of the front face (14) at the wearer's convenience. Preferably, the wedge (10) and resulting buckle may be of arbitrary depth but should be dimensioned such as to accommodate off-the-shelf waistbelts between 3 and 4 cm in width.

[0012] Figure 2 shows an embodiment with open guidance provided by a bilateral elevation (23) opposite the wedge base (11). As may be gathered from Figure 3, the buckle may be of the center-bar or center-post variety, its center bar (17a) showing a recess (16) for supporting the buckle's tongue. In the case of an interchangeable buckle, such tongue, forming an integral part of the product, should be attached to the wedge base (11) and kept from slipping sideways.

[0013] In the variants as per Figure 4 and Figure 5, a vertical (12) or wedged strap guide (12b) and front face (14) instead delimit a guiding slot (13). As best seen in Figure 5, the wedged strap guide (12b) augments the wedge (10) and guides the belt strap close to the wearer's abdomen. As depicted in Figure 6, such "closed guidance" may be achieved by a simple frame (18), with a parallel guiding slot (13) being formed betwixt the guide (12) and front face (14). An alternative embodiment may take the form of a shield (19) exhibiting a prong (20) protruding opposite the front face (14).

[0014] The skilled person will appreciate that while the drawings place emphasis upon the edges of the wedge (10), the latter may be wholly or partially filled, such as with silicone, or fabric-covered, for example, at its base (11). Similarly, while displayed as straight, some edges may bend without departing from the scope of the invention. For instance, the wedge base (11) may be chamfered or otherwise adapted to the shape of the lower abdomen.

[0015] All variants share the physical commonality that the leather strap passes at a controlled distance from the wearer's body. While the frame (18) and shield (19) of Figure 6 provide a dedicated strap guide, the bilateral bars of the center-bar (17a, 17b) embodiments as per Figure 3 essentially serve the same purpose. As outlined above with reference to Figure 2, fixation in these embodiments may be achieved by means of a tongue (24 - Figure 7 ) or prong (20 - Figure 8).

[0016] A buckle especially suitable for air travel may be manufactured from hard plastic or any material that will pass airport security screening. An exchangeable buckle consisting of such material can be assembled using non-metallic screws and proves most comfortable both during inspection and while sitting for extended periods of time.

Industrial applicability

[0017] The invention is applicable, inter alia, throughout the apparel industry.
