Description

  The present invention relates to prevention of falling of articles stored in a shelf due to vibration such as an earthquake.

  There are many technologies for the fall prevention device for articles stored in the shelf, but all simple technologies have complicated mechanisms for the vibration sensing unit that detects vibration and the operation unit that prevents dropping, Mechanical and electrical transmission caused operational delays and was not practical enough.

  In addition, the technology of the device that is expected to prevent all articles stored in the shelf from being dropped mechanically and functionally has a drawback that it has not been used industrially.

  In general, an apparatus that is expected to prevent all articles stored in a shelf from falling is expensive, and it is not originally intended to be installed on an open shelf used for display and sale of goods.

As an improvement measure, this is a device that provides a method for preventing an article stored in a shelf at a low cost with a simple structure and little delay in mechanical operation.

  The problem to be solved is that the conventional simple mechanism device senses the vibration of the earthquake and the operation after the reaction is slow, and the articles stored on the shelf cannot be sufficiently prevented from falling.

  According to the present invention, the fall prevention unit comprising the fall prevention unit, the arm part and the weight part provided in the general apparatus senses vibration such as an earthquake, and the biasing means is provided by the inertia of the fall prevention unit. It operates even if it is not used, and the fall prevention part moves to the storage article loading / unloading surface, which is the front of the shelf, so that the article stored in the shelf can be prevented from falling. The most important feature is the position of the rotation center axis serving as a fulcrum.

  The shelf stored item fall prevention apparatus of the present invention can be manufactured at low cost, can be added to existing shelves relatively easily, and has the advantage that it operates simultaneously with the response to earthquake vibration.

  The fall prevention means part consisting of the fall prevention part, arm part, weight part and fulcrum part senses the vibration of the earthquake by its own weight, and the parts that detect and operate to prevent the fall of the articles stored in the shelf are the same structure This is a simple mechanism that does not use power as an independent sensing unit and biasing means.

  FIG. 1 is a perspective view of the apparatus of the present invention, showing a stationary state before vibration is sensed. The upper shelf 1 is separated for the purpose of illustrating details.

  A supporting portion 5 is provided at an intermediate position between the upper shelf 1 and the lower shelf 2 in the shelf back column portion 3 that supports the shelf.

  FIG. 2 is a side view of the apparatus according to the present invention, in which the shelf back column 3 is provided with a support 5, and the fall prevention means 4-1 is installed so that the center of gravity of the fall prevention means 4-1 is on the back side. It is the figure which showed that the part 4-1 was in contact with the shelf back support | pillar part 3 at the upper fulcrum part 7, and was stabilized.

  FIG. 3 shows the structure of the side view of FIG. 2 as a line, and is an explanatory diagram of the operation of the general apparatus, shows a weight part 4-3, and the gravity center position of the fall prevention means part 4-1 is on the front side. It is the figure which showed that it exists in the back direction of a shelf from the fulcrum center line C-1.

  FIG. 4 shows that the position of the center of gravity of the fall prevention means 4-1 when the vibration in the front-rear direction is shaken from the front side of the shelf to the rear side of the shelf with respect to the shelf device. FIG. 4 is a diagram showing that the front side fulcrum center line C-1 moves to the front side of the shelf due to the inertia due to vibration, and the fall prevention unit 4-2 moves to the front side of the shelf.

  FIG. 5 is an explanatory diagram of the operation of the general device according to claim 2 of the present invention device, and is a diagram showing the structure by lines, with respect to the shelf device, the vibration in the front-rear direction is changed from the shelf back direction to the shelf. In the case of shaking in the front direction, the inertia of moving the fall prevention means part 4-1 toward the shelf rear side acts, but the fall prevention means part 4 with the upper fulcrum part 7 in contact with the shelf back column part 3 as a fulcrum. -1 front side fulcrum 6-1 is guided by the fulcrum moving guide section 5-1, front side fulcrum center line C-1 moves to back side fulcrum center line C-2, and back side fulcrum center 6-2 FIG.

  6, after the operation of the general apparatus described in FIG. 5, the fall-preventing means 4-1 operates so that it falls to the front side of the shelf by its own weight with the back side fulcrum 6-2 as a fulcrum and falls to the front of the shelf. It is the figure which showed that the prevention part 4-2 moved and the storage goods of a shelf did not fall.

Although not shown, the fall prevention unit 4-2 is moved to the position illustrated in FIG. 4 by the subsequent vibration.

  FIG. 7 is an explanatory diagram of the operation of the general apparatus according to claim 3 of the present invention device, and is a diagram showing the structure with lines, and the operation of the fall prevention means section 4-1 is shown in FIGS. 6, but the end of the fall prevention curtain 8 is respectively engaged with the fall prevention curtain latching section 9 and the upper shelf fall prevention curtain latching section 10 of the fall prevention section 4-1. It is the figure which showed the state which accommodated the fall prevention curtain 8 between the fall prevention part 4-2 and the upper shelf 1 with the folding means.

  FIG. 8 is an explanatory view of FIG. 7, and the operation of the drop prevention means 4-1 is a view after the operation similar to the description of FIG. 4, FIG. 5 and FIG. 2 and the fall prevention curtain 8 are provided to show that the stored articles on the shelf do not fall.

  There is an effect of preventing the articles stored in the shelf from falling by moving the fall prevention means 4-1 by vibration.

  By obtaining the maximum effect while simplifying the operating principle, it can be applied to applications that are indispensable for reducing equipment costs and for earthquake countermeasures in an open front shelf.

FIG. 4 is a perspective view of the embodiment, showing the upper shelf in a separated view and details. These are side views of an Example. These are the explanatory drawings which showed the structure of an example with a line, and show the resting state before an outline device operation. These are the explanatory drawings which showed the structure of an example with the line, and show the state after an outline device operation. These are the explanatory drawings which showed the structure of the example with the line, and show the state of the operation start of the general device according to claim 2. These are explanatory drawings which showed the structure of the Example with the line | wire, and show the state after the general apparatus operation | movement of Claim 2.
