A suction mounted door hook has two suctions cups and a hook connected to the two suction cups. Each suction cup has a cup portion and a loop portion attached to the cup portion such that the loop portion and a surface of the cup portion define an opening. There is a recess on that surface of the cup portion and a pair of spaced apart loop projections on the top surface and preferably on the bottom surface of the loop portion that have a recess between them which is opposite the recess in the cup portion. The hook has an S-shaped body and two legs, one leg being within the opening of each suction cup. The hook can be in either an extended position or a folded position. Surfaces and projections on the hook mate with the recesses in the suction cups to hold the hook in either position.

A tube hanger for a very early smoke detection system is provided. The tube hanger includes a tube hook configured to receive a tube, a suspension arm having a first end extending from the tube hook and a second end, and a support coupling mechanism extending from the second end of the suspension arm. The support coupling mechanism includes a first attachment mechanism configured to be coupled to a first frame type, and a second attachment mechanism configured to be coupled to a second frame type. The tube hanger further includes a third attachment mechanism extending from the support coupling mechanism and configured to be coupled to a third frame type.

A screed hook apparatus includes a tubular collar having an opening through a sidewall thereof. A tubular retainer member is aligned with the opening on the collar and extends away from an outer surface of the collar. The retainer member has a threaded internal wall surface. The apparatus also includes an arm forming a hook shape. The arm has a first portion extending away from the collar and a second portion extending transverse to a direction of extension of the first portion such that a surface of the second portion of the arm faces the sidewall of the collar. A set screw has a threaded portion to engage the threaded internal wall surface of the retainer member, and a handle is attached to the set screw.

An improved tool belt hook is selectively deployable on a portable tool or device. The hook structure is deployable in selected directions or positions on the tool. A stowed position is also preferably included wherein the hook structure is substantially contained within confines of the tool body to be out of a user's way. A closely integrated pushbutton release may allow the hook to rotate between selected operative positions and automatically engage to such position. The button is easily operated while effectively remaining within confines of the tool body. The tool hook assembly is compact and low cost.

A hook includes a hook seat, a rivet, and a fixing bolt. A rivet cap and a rivet post are provided on the rivet. The rivet post includes a rivet rod and a rivet seat. A diameter of the rivet seat is greater than a diameter of the rivet rod. A first step is formed between the rivet rod and the rivet seat. A first cut surface and a second cut surface are provided on both sides of the rivet rod, respectively. The rivet and fixing bolt are matched with each other and fixed to the hook seat. The first step abuts against one side of the hook seat. An end face of the fixing bolt abuts against the other side of the hook seat to lock the hook seat between the fixing bolt and the first step.

In one preferred form of the present invention, there is provided hook system 10 for hanging school bags 18. The hook system 10 comprises: a body 10 providing a series of protective recesses 14 each having a projection 16. Each projection 16 allows a school bag to be hung therefrom using a top hanging strap 20 of the school bag 18. Each protective recess 14 shields the corresponding projection 16 to assist with preventing personal injury or eye damage associated with a person accidently moving towards the projection.

An system for drying a wet area of a building includes an elongated flexible duct and a plurality of hanger structures engaged with the duct at locations spaced therealong. Each hanger structure includes a connector tab adapted for engagement with a suspension member and a pair of diverging adhesive panels for adhesive engagement with the duct. The suspension members engage ceiling members to support the duct from an air source to the wet area.

A clasp hanger includes a hanger hook including an elongated part. The hanger hook has a hanger hook section and a neck section opposite the hook section. The neck section is expandable to allow the clasp hanger to be quickly hung on a support object such as a branch. The clasp hanger further includes an object attachment device attached to the neck section of the hanger hook. This object attachment device is configured for attaching an object such as one configured to dispense a chemical or formulation useful in pest management. The hanger hook, and object attachment device are disposed such that, after the support object is pushed through the neck, the hanger hook automatically rotates such that the support object is disposed at an interior part of the hanger hook that is away from the neck section. This prevents the support object from passing back through the neck section.

A fastening device for installing a fitting or a holding clamp in a hole in a thin wall. The fastening device includes a head area with fitting parts attached thereto for clamping or enclosing a portion of the fitting or holding clamp between the head and the thin wall. The fastening device also includes a body area that proceeds from the head area and penetrates the hole in an installed condition. Proceeding from the end of the body area are two spring legs which are directed rearward toward the thin wall, and which are supported by sloping foot-like ends on two diametrically opposite, parallel edges of the hole. The fastening device forms guide strips which protrude laterally from the body area, and which are guided into suitable notches (between the opposite edges of the hole in the thin wall.

Disclosed herein is a clasp hanger for hanging. The clasp hanger includes a hanger hook comprised of an elongated part. The hanger hook has a hanger hook section and a neck section opposite the hook section. The neck section is expandable to allow the clasp hanger to be quickly hung on a support object such as a branch. The clasp hanger further includes an object attachment device attached to the neck section of the hanger hook. This object attachment device is configured for attaching an object to be hung. The object may be, for example, configured to dispense a chemical or formulation useful in agricultural pest management. The hanger hook, and object attachment device are disposed such that, after the support object is pushed through the neck, the hanger hook will automatically rotate such that the support object is disposed at an interior part of the hanger hook that is away from the neck section. This prevents the support object from passing back through the neck section.
