A hunting blind, components thereof, and associated methods. The blind includes a window or door comprising a closure that when open defines an opening for seeing out of the blind and/or providing ingress and egress for an interior of the blind. The closure comprises first and second closure strips and a slider movable along the closure strips to open and close the opening. The first closure strip includes a first rib having a longitudinal axis extending along a length of the first closure strip. The second closure strip includes a first channel having a longitudinal axis extending lengthwise of the second closure strip.

A child resistant zipper closure for a bag includes a slider having a flexible tab with a torpedo. To open a zipper closure, the tab must be held in a downward position to engage the torpedo between male and female tracks and result in separation of interlocked complementary profiles, while the slider is moved along the zipper closure.

An adjustable-width cover for removable installation on a safety gate, the safety gate having a width defined by opposed end posts and a height defined by top and bottom support rods, the cover includes a flexible, frameless, planar, and generally-rectangular cover member, the vertical height of the cover member is less than the safety gate, the width of the cover member is greater than the width of the safety gate and covers the front side of the safety gate and at least a portion of the back side of the safety gate when installed. The cover is maintained in tension using a plurality of adjustable length straps extending from each side edge of the cover on the back side of the safety gate. A motion sensor, with an adjustable sensitivity level, is used to detect motion and provide notification when the cover is moved, climbed on, or otherwise disturbed.

A protective slider zipper, comprising a zipper and a slider for opening and closing the zipper, wherein an upper part of the slider is in a protection structure; the root part of the protection structure is in a bending structure capable of being repeatedly bent; a first work support surface at one side of the protection structure is fixedly connected with a first slider hand; the zipper comprises a female strip and a male strip; and the female strip is connected with and separated from the male strip through the slider.

A hook and loop fastener includes a first strip having one of loops or hooks and a second strip having another of the loops or the hooks. The first strip has a first longitudinal track orthogonal to the first strip. The second strip has a second longitudinal track, orthogonal to the first longitudinal track. A slider is provided that has an interface disrupting member extends outwardly. A gripping element is provided for manually moving the slider along the first longitudinal track and the second longitudinal track in a first direction and a second direction. Movement of the slider in the first direction brings the first strip into engagement with the second strip. Movement of the slider in the second direction draws the interface disrupting member through the interface between the first strip and the second strip, thereby separating the first strip and the second strip.
