Abstract: A panic barrier for containing pedestrians on the occasion of big events. Said barrier is such as not to overturn whenever the crowd presses against the parapet, thanks to the presence of a fulcrum element integral with the lower portion of the parapet on the side opposite to that of the footboard on which pedestrians walk. Advantageously numerous variants of modular fences can be created by combining a plurality of panic barriers with each other.

Abstract: The present invention teaches an apparatus, system, and method for hanging or supporting lumber or similar materials using standard metal t-post which can be used to construct fences or outdoor structures. A first iteration, incorporating fence bracket disclosed herein, eliminates the need for the use of wooden posts to erect a wooden board fence. A second iteration, incorporating a lumber bracket, is used to attach construction lumber to a plurality of t-posts in order to form a basic support structure, in whole or in part, for a variety of outbuildings. The two variations of the bracket may be used independently, or in conjunction with one another, depending on the particular application. The system may be used to erect a new board fence, transition from an existing wire t-post fence to a board fence, and to construct, or assist in the construction of, sheds, coops, barns, and other similar outbuildings.

Abstract: In as first aspect of the invention, this is achieved by a joining system for furniture parts comprising female coupling recess formed in a first furniture part, a male coupling tongue projecting from an adjoining second furniture part, said female coupling recess being adapted to receive the male coupling tongue, said male coupling tongue comprising a first locking element configured for a snap joint interlocking engagement with a matching second locking element in said female coupling recess, the male coupling tongue being configured to be more flexible than the female coupling recess. The joining system comprises an upper guiding surface arranged on a first side of the female coupling recess on the first furniture part, forming an essentially non-resilient guide for the male coupling tongue upon insertion thereof, limiting movement of said male coupling tongue in a direction towards said first side of the female coupling recess.

Abstract: Modular autonomous mobile fence, delimiter of grazing areas. It consists of two structures (10, 20) arranged opposite and distant from each other. Each structure (10, 20) is composed of at least two movable towers, arranged at the ends of the very same row and structurally linked to each other to form a movable row. An electric wire conductor (14, 15) is arranged between these two rows (10, 20) and forms a closed quadrilateral that delimits a closed grazing area (16). Said rows with towers and the area delimited by the electric fence can be selectively moved from one lot to the next, together with the animals kept therein. Said electric fence must have means of separation (31, 32) of the electric conductor from the ground (14, 15) and at least one of the mentioned towers must have means of tensioning (34) the electric conductor.

Abstract: A foldable clamp-on desk lamp with a multi-angle adjustment function includes: a lamp base part, a clamping base, several supporting rods, and detachable rotating shaft assemblies through which the several supporting rods are movably connected and the lamp base part is connected to the uppermost supporting rod. The lowermost supporting rod is detachably connected to the clamping base. The detachable rotating shaft assemblies can achieve folding and telescopic functions, complete disassembly, repeated disassembly, assembly and change, and long service life. By the design combining a Fresnel lens and convolutional lines, light is continuously scattered and recombined when passing through the convolutional lines, so that the outgoing light is more uniformly, soft, and not dazzling. A plurality of inserting holes are formed at the upper side and top end of the clamping base, thereby facilitating multi-directional assembling of the supporting rods and achieving wide application of the clamping position.

Abstract: Disclosed is an apparatus for use with an instrument handle, the apparatus including a housing, a knob receivable in the housing, the knob having a key hole structure to receive an instrument bulb and neck, a slot in the housing to receive the knob, wherein the knob is pressed into the slot to facilitate installation and removal of the instrument bulb and neck.

Abstract: A plug-in connector has two pushbuttons arranged laterally thereon. An annular, asymmetric spiral spring is inserted in such a manner that the spiral spring, in its locking orientation, permits the respective pushbutton pin to move into the plug-in connector housing and prevents the pushbutton pin from moving out of the plug-in connector housing. The spiral spring can tilt from its locking orientation into its release orientation when arranged with its inner region in a release groove of the pushbutton pin. In its release orientation, the spiral spring permits the pushbutton pin to move out of the plug-in connector housing. This permits actuation similar to a ballpoint pen with only a few components and with high operating comfort.

Abstract: An adjustable fence post coupler is shown and described. The adjustable fence post coupler includes a fence connection plate. The fence connection plate has a plurality of apertures located through the plate. The apertures are configured to allow for fasteners to be placed though and into the fence securing the fence connection plate to the fence. The fence connection plate is connected to at least two connection bolts. The connection bolts are connected to a fence post coupler strap. The connection strap has at least two tubes attached to the connection strap. The connection bolts go through the tubes securing them to the fence post coupler strap. The fence post coupler strap is connected to a fence post. The adjustable fence post coupler is used to adjust the distance from the fence post that the fence is installed at. This allows for a perfectly linear fence.
