A structure formed by temperature difference includes an enveloped part, an enveloping part, and a low heat transfer layer. The enveloped part has a free section and an engagement section. The enveloping part defines at least one holding space corresponding to the engagement section. The holding space is dimensioned to be slightly less than the engagement section and can be thermally expanded to be larger than the engagement section by heating the enveloping part to reach a predetermined temperature difference over the enveloped part, so that the engagement section can be put into the holding space. When the enveloping part is cooled, the holding space can shrink, causing the enveloping part to tightly hold the engagement section. The low heat transfer layer, which has a thermal conductivity less than each of the two parts, is disposed in the holding space, between the engagement section and the enveloping part.

A mounting system capable of mounting objects to support structures. The mounting system includes a wall mount including a display bracket configured to hold the object, a fixed support bracket coupleable to a vertical support structure, and a linkage assembly. The linkage assembly has a low-profile stowed configuration in which the object is held in a raised position close to the support structure. Tilt adjustment mechanisms are used to adjust the tilt of the display bracket.

A mounting bracket (320) for trapezoidal rib profiles is disclosed. This mounting bracket (320) includes an upper section (330) and a lower section (350). A first leg (352a) in a second leg (352b) extend from a lower portion of the upper section (330) in diverging relation to one another. Each of these legs (352a, 352b) is deflectable through a certain range of motion to accommodate installation of the mounting bracket (320) on a variety of different trapezoidal rib profiles.

A grease gun mounting assembly for mounting a grease gun to a piece of equipment requiring routine greasing includes a connector, which has engaged thereto a first tube and a second tube with the first tube and the second tube being substantially parallel. The first tube is sized for insertion of a grease gun into an upper end thereof. The second tube is sized for insertion of a hose extending from the grease gun. The connector is engageable to an object, such as a piece of equipment requiring routine greasing, so that the first tube and the second tube are selectively engageable to the object. The grease gun and the hose can be inserted into the first tube and the second tube, respectively, for mounting the grease gun and the hose to the object.

A disengageable connection includes a back portion, a front portion, a handle portion, and a clutch plate portion, the back portion and the front portion are configured to removably secure a tube using the clutch plate portion and the handle portion.

The present invention relates to a trench cross-section reference line setting device, comprising: a trench reference line setting body unit (100) for setting a trench cross-section reference line, wherein the trench reference line setting body unit (100) has a sensor unit (10) at the center thereof, two horizontal units (20) orthogonal to each other on the upper surface thereof, and three laser light source units (30) and a grid photographing unit (110′), respectively, on the side surfaces thereof; a reference line setting tripod unit (200) rotatably coupled to the trench reference line setting body unit (100) and having a posture adjusting unit (230) and a height adjusting unit (250); and a trench stratum analysis server (300) for receiving a fault image photographed by the grid photographing unit (110′) of the trench reference line setting body unit (100) and creating a stratum map of a trench cross-section structure.

A latching assembly includes a linear component and a base component. The linear component is configured to be coupled to a first element and includes at least one retention projection. The base component is configured to be coupled to a second element and includes a channel and at least one retention feature. The linear component is configured to be slidably received within the channel of the base component and the at least one retention feature of the base component is configured to engage the at least one retention projection of the linear component to retain the linear component within the channel of the base component.

The present invention relates to a ‘prop up’ or support device for supporting counters or sinks during renovation, restoration, mitigation, or other similar situations. More specifically, the prop up device is a rectilinear shaped telescoping device having telescoping arms that can extend to different heights to support kitchen counters, bars, or sinks of different heights, and ensures the kitchen remains functional during repairs, renovations, or the like. The prop up device enables the telescoping arms to easily collapse, fold, and store when the support device is in the storage orientation (i.e. not in use).

The present application relates to a shop chair with a seat cushion supported by a strong, light-weight base assembly with an elevated central hub that threadably receives a central column to adjust the height of the seat cushion. The base includes several vertically oriented thin plate legs that extend radially outward and downward from a central hub. The outer ends of the legs are joined by a stabilizing ring with a diameter larger than the seat cushion. Oversized caster wheels and the large footprint of the base provide a stable work platform. The seat cushion can be selectively lowered until the bottom of the central post is proximal to or contacts the ground. The chair and its base are particularly suited for work done closer to the ground.
