Abstract:
A fixing device which can be fixed to a surface such as a ceiling and receive a perforated section comprises a plate for fixing it to the surface and a support for receiving the perforated section. The support has a wall substantially perpendicular to the plate and at least two claws with the same orientation which cooperate with corresponding perforations of the perforated section. The wall includes a precut locking lug which can be bent into another perforation and cooperate with an edge of that perforation to immobilize the perforated section against movement in translation.
Abstract:
The present invention provides a microphone support which includes a restriction groove 520 between a universal ball 50 and a mounting member 70 in order to restrict the rotating angle range of the universal ball 50 rotating with the axis line of a pipe through-hole 510 centered, so that the direction axis L of a microphone is restricted to have a designated swinging angle range with the talker side of the microphone centered. Therefore, no breaking wire by wire-twists is generated, and since the microphone is prevented from facing to loudspeakers owing to careless handling, no howling is also generated.
Abstract:
A fastening unit for securing brackets on a frame of a computer housing includes a seat having at least two parallel mounting walls that define a mounting space therebetween, and at least one pressing member that has a pressing part, that is disposed in the mounting space, and that is pivoted to the mounting walls so as to be rotatable relative to the seat between a pressing position, in which the pressing part thereof presses a portion of the respective bracket against the frame, and a releasing position, in which the pressing part thereof is moved away from the portion of the respective bracket.
Abstract:
An assembly 10 and a method 200 which utilizes the assembly 10 to selectively and structurally strengthen and rigidize and/or stiffen a member 150 which is operatively disposed within an article of manufacture, such as an without limitation, a vehicle. Particularly, the assembly 10 includes a selectively expandable portion 18 which is stretched along an inflation wand 12 and is then inserted into the member 150 via a relatively small aperture 155 formed within the member 150. Selectively expandable portion 18 is then inflated with a material 52 to support the member 150.
Abstract:
The Pyramid Easel is a display holder for primarily flat objects, which rests on a surface support area on eight nullfeetnull in a rectangular configuration, and on the contact areas of two easel base options. The easel is composed of ten main contiguous, triangular and polygonal (modified triangular) planes with additional contiguous triangular and trapezoid planes as part of optional base(s). On each of two display sides, objects are supported by a modified triangular center face, a triangular wing on each side of the center face, with two base options which brace the bottom of display objects, and aid in expansion control through friction with the surface support area. Front and mirrored back, and mirrored side wings, are connected by modified triangular swing arms, which are essentially the dynamic planar backsides of the front and back center pyramids, meeting at the crown of the embedded pyramids and nullswingingnull inside the center of the easel structure. The easel self-adjusts simultaneously its expandability, the angle of display, and the wings' horizontal extensibility to optimize holding the weight and shape of the display object; when an expansion control device is incorporated, either a maximum useful expandability or any intermediate useful display angle can be fixed and/or adjusted. The easel can be assembled from one planar square of material. The easel can be constructed in a frame embodiment from the edges of the intersecting planes and the sides of a material square, or inclusive with decorative plane surfaces. In one embodiment, arcs replace selected plane angle vertices for rounding edges, points, and corners of an easel.
Abstract:
A leg assembly (12) for a tripod (10) comprises a first leg unit (13), a second leg unit (14) and a third leg unit (15). First leg unit (13) includes legs (13A and 13B). Second leg unit (14) includes legs (14A and 14B). Legs (14A and 14B) are laterally spaced from each other and held in fixed position by an upper cross member (17) and a lower cross member (18). Legs (13A and 13B) can slide through openings in upper cross member (17). Leg (15A) can slide through an opening in lower cross member (18). Upper cross member (17) includes a first fixing means for selectively locking and unlocking the first leg unit in position. The lower cross member (18) includes a second fixing means for selectively locking and unlocking the third leg unit in position. A first lever (23) is used to selectively actuate the first fixing means. A second lever (24) is position adjacent to first lever (23). Second lever (24) is connected via a connecting means such as torsion bar (25) to the second fixing means. First lever (23) and second lever (24) can be actuated independently to enable either of the first or second fixing means to be actuated. Alternatively, due to the close proximity of first lever (23) and second lever (24), both levers can be actuated simultaneously to effect actuation of the first fixing means and the second fixing means.
Abstract:
A shock absorbing apparatus in a positioning apparatus including a stage apparatus is disclosed. The positioning apparatus includes a main body apparatus for mounting the stage apparatus thereto, and a chamber for maintaining a region, in which the stage apparatus is disposed, under a condition of vacuum or purged ambience. The shock absorbing apparatus includes a shock absorber provided at a stroke end of the stage apparatus, and a support member provided separately from the stage apparatus, to which the shock absorber is fixed. In the shock absorbing apparatus of the present invention, the shock absorbing apparatus is fixed to the support member provided separately from the stage apparatus including a driving system, and accordingly an increase in size of the stage apparatus can be prevented, and high-speed and highly-precise positioning of an object to be positioned can be performed in a non-atmospheric ambience.
Abstract:
A structure for hanging objects is disclosed to include a base level, a first strap body, and a second strap body. The first strap body is bonded to the base level such that a plurality of first slots each having a predetermined breadth are formed between the first strap body and the base level. The second strap body is stackably bonded to the first strap body such that a plurality of second slots each having a predetermined breadth are formed between the first strap body and the second strap body. Each of the first slots corresponds to at least two of the second slots.
Abstract:
Holding devices are disclosed that are configured to hold an optical component of an optical system without actually contacting the optical component. An embodiment of such a holding device is operable in a vacuum environment, such as used in an Extreme UV (EUV) optical system, and effectively holds the optical component without imposing stress on the optical component. The embodiment includes a receptacle configured to receive a mounting portion of the optical component. The receptacle includes at least one gas bearing. At least one exhaust groove (or analogous feature) is situated and configured to scavenge gas discharged by the gas bearing and to exhaust the scavenged gas so as to avoid burdening the vacuum chamber with the discharged gas. Desirably, the receptacle defines multiple gas bearings each including a respective air pad, each desirably including at least one respective exhaust groove. As a result of the non-contacting gas bearings, stress and strain imposed on the holding device are not transmitted to the optical component being held by the device.
Abstract:
A plane display with foldable support. The plane display comprises a base and a back plate mounted on a plane display panel. The back plate pivots onto the base through a bolt. The back plate has a fixing piece and a first arm. An operating rod movably connected to the fixing piece and the first arm slides between a first position and a second position. When the operating rod is in the first position, the back plate is fixed to the base at a first angle. When the operating rod is located in the second position, the operating rod releases the back plate from the base, such that the back plate rotates with respect to the base to a second angle.
