Disclosed are belt adjustment systems, particularly for wearing around a user's waist, that permit a continuum of belt loop sizes or a larger selection of belt loop sizes. The belt adjustment system includes an elongate belt member having a first end, a second end and a series of teeth positioned on an inner surface near the second end and a fixation member having first and second adjustment elements.

The invention relates to a universal double-sided belt buckle, which comprises a buckle body, a mounting member and a buckle pin, the left end of an upper sheet body and the left end of a lower sheet body are both integrally formed with extension sheets extending downwards, a clamping interval is arranged between the free ends of the two extension sheets, the left side of the mounting member, at the position corresponding to the first end of the buckle pin, is concavely provided with an accommodating recess which is communicated with the through concave cavity and used to accommodate the part of the buckle pin positioned at the mounting member and make it be able to rotate. Compared with the prior art, the buckle body is detachably connected with the mounting member, so that the utilization rate of the buckle body is improved.

An undergarment including a front panel having a top edge, an elastic band arranged on the front panel along the top edge and extending beyond the front panel parallel to the top edge. The undergarment further includes a back panel having a top edge, the elastic band arranged on the back panel along the top edge and extending beyond the back panel parallel to the top edge, and a pair of connectors secured to the elastic band and configured to attach to a side seam of a blouse or shirt.

A belt having a strap and a reversible belt buckle is provided where the strap has a top surface and a rear surface. The buckle includes an inner frame member having a first end having a slot to receive the first end of the strap and a second end having a first hinge section. The buckle further includes a top member having a rear surface having second hinge section disposed at a central axis. The top member has a pin disposed on the second hinge section. The top member is rotatable about a hinge point from a first position wherein the rear surface of the top member at the first edge faces the front side of the inner frame member, to a second position wherein the rear surface of the top member at the second edge faces the rear side of the inner frame member. The top member substantially covers the entire inner frame member when in use.

The present invention comprises a closed loop elastic strap having at least a primary thickness, a width and an adjustable length. The length is adjustable by feeding the elastic strap through a buckle with one end of the elastic strap attached to a loop with another portion of the elastic strap fed through the same loop and the other end of the elastic strap attached to a portion of the same buckle. The closed loop elastic strap can be stretched around (but not limited to) the end of a picnic table to hold a tablecloth in place or around the top of (but not limited to) a beach chair or lounge chair to hold a towel in place during windy or adverse conditions.

A method and system for personal protective equipment, such as a respirator mask, having a nosecup that is removably coupled to the item of personal protective equipment by at least one of an electronics housing and at least one voicemitter. A respirator mask includes a frame including a voicemitter aperture, a voicemitter, and a nosecup removably coupled to the frame by a rotation of the voicemitter by a predetermined amount to removably lock the nosecup to the frame voicemitter aperture. The mask further includes electronics components, which are housed in an annular electronics housing located within the front portion of the mask body 14 and in contact with a front portion of the nosecup. The nosecup may further be removably coupled to the mask frame by coupling between the annular electronics housing and the mask frame.

A power supply for an item of personal protective equipment and a method and system for removably coupling the power supply to the item of personal protective equipment, such as a respirator mask. The removable battery cartridge is attached to the mask body in the user's chin area, below the location at which a respirator would be or is attached. Thus, the power supply (battery cartridge) is out of the user's way and is at a location that allow the user to couple or uncouple the cartridge from the mask quickly and easily, even when the user is wearing gloves. In one embodiment, a mask body includes a lower surface and power supply that is removably couplable to the mask body lower surface.

A buckle having an adjustable loop end forming a primary plane with opposing side walls. The adjustable loop end has a central bar positioned between a first strap opening and a second strap opening. A pair of slots operable to receive the terminal ends of the central bar are recessed into the interior surface of the opposing side walls with the bottom edges of the slots being longer than the top edges. A pair of tabs on opposite ends of the central bar extend outward from the central bar along a longitudinal axis of the primary plane and towards the second strap or belt opening. Optionally, a protrusion extends from a lower surface of the fixed loop end wherein the protrusion is positioned at a right angle with respect to a vertical axis of the primary plane.

A locking slide clip includes a C-shaped body and a door. The C-shaped body defines an opening in communication with a slot. The door is pivotably engaged with the C-shaped body opposite the slot and includes a protrusion.

A belt buckle with long usage rate, which includes a buckle body and a mounting member, wherein the left side surface and the right side surface of a mounting rod body are both cutting planes, the left side surface of the mounting member is provided with a through concave cavity, the left end of an upper sheet body and the left end of a lower sheet body are both integrally formed with extension sheets extending downwards, a clamping interval is arranged between the free ends of the two extension sheets, the mounting rod body is clamped into the through concave cavity through the clamping interval and is rotatably arranged in the through concave cavity. The buckle body is detachably connected with the mounting member, so that the free combination of different buckle bodies and different mounting members is realized.
