1. Field of Invention
The invention relates to holding devices and more particularly to an LED panel holder with improved characteristics.
2. Description of Related Art
An LED panel is a small video display which uses light-emitting diodes (LEDs). LED panels are sometimes used as form of lighting, for the purpose of general illumination, task lighting, or even stage lighting rather than display.
LED panels are fragile. Hence, how to safely package an LED panel in a shipping container (e.g., box) is important. Typically, a holder is mounted to an LED panel prior to putting into a box. Moreover, package cushioning is added to stably hold the LED panel in the box.
However, the LED panel supported by two arms of the conventional holder is not stable since box back and bottom may be uneven. Moreover, its packaging is somewhat difficult as complained by many employees. Thus, the need for improvement still exists.
It is therefore one object of the invention to provide an LED panel holder comprising a rectangular case having an open front and comprising a longitudinal groove on a central portion of back, a plurality of slots on one side, a plurality of hooks on the other side, the hooks being adapted to lockingly engage with the slots, a plurality of projecting members on top, and a plurality of recessed members on bottom, the recessed members being complementary to the projecting members; and a support assembly comprising a support releasably secured to the groove, a base having one end pivotably secured to bottom of the groove, and an arm having one end adjustably secured to the support and the other end pivotably secured to the other end of the base, wherein the support assembly is adapted to retract into the groove to render the back of the case to be substantially flat.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
Referring to
The support assembly 2 comprises a support 2a, an arm 2b, and a base 2c rested upon a flat surface. The support 2a is elongated and has a section of U. The support 2a has a plurality of fasteners (e.g., screws) 2ac for securing the support 2a to the case 1, and a top cross bar 2aa. The support 2a is complimentarily fastened in a longitudinal groove 1a on a central portion of the back of the case 1. The groove 1a has a cross-section of rectangle. The support 2a comprises a plurality of equally spaced apart holes 2ab along either side.
The arm 2b comprises two opposite spring depressible sliding pins 2ba at one end and has the other end pivotably secured to one end of the base 2c. The sliding pin 2ba has a handle 2bb so that aligning the sliding pins 2ba with the holes 2ab by holding the handles 2bb and releasing the handles 2bb can insert portions of the sliding pins 2ba into the holes 2ab to secure the arm 2 to the support 2a. To the contrary, pulling the handles 2bb to cause the sliding pins 2ba to clear the holes 2ab can detach the arm 2b from the support 2a. That is, a coupling point of the support 2a and the arm 2b is adjustable.
The other end of the base 2c is pivotably secured to two pivotal mounts 1j at both sides of an inverted U member 1i which is provided at the bottom end of the groove 1a respectively (see
The protective cap 3 is releasably fitted on top of the case 1. One side of the case 1 is provided with a plurality of (two) spaced slots 1d and the other side thereof is provided with a plurality of (two) hooks 1e. The hooks 1e of one case 1 can be inserted into the slots 1d of another case 1 so that the two cases 1 can be coupled together transversely.
A rear half portion 1k of the bottom of the case 1 has a higher elevation that a front half portion 1m thereof. That is, the rear half portion 1k is recessed vertically as shown in
