Description

  The present invention is an uncertain fall prevention function due to bending of the net in a net for preventing a fall of the object such as a file or a product placed on the shelf in the event of an earthquake. It is related with the holding | suppressing tool for mounted article fall prevention nets which complements nature.

  Conventionally, articles such as files and products are placed on wooden shelves or steel shelves in various places including offices and factories.

  As a method for preventing items such as files and products placed on the shelf from falling from the shelf in the event of an earthquake, the shelf column or top plate of the shelf is to be prevented from falling over. Was fixed to the floor or wall with wires or metal fittings.

  However, in the above method, in the case of a large earthquake, particularly an earthquake with severe rolls, there is a risk that articles such as files and products placed on the shelf will fall even if the shelf itself is fixed to the floor or wall and does not fall down. is there. In order to prevent such a risk, the name “placement prevention device” of the idea of utility model registration No. 3170539 by the applicant of the present application has a height approximately in the middle of the placement space formed by the upper and lower shelf boards. , The belt with the male one-touch buckle and the belt with the female one-touch buckle are fixed to the left and right side plates (posts), respectively, and when the respective one-touch buckles are fitted, the right and left side plates ( A mounted object fall prevention tool characterized in that a belt is stretched between the front surfaces of the support columns to prevent the mounted object from falling.

Utility model registration No. 3170539

  In the above publication, there was no particular problem when a file or book was targeted as an object to be placed, but there was a problem that it did not function at all when an article lower than the height between the shelf and the belt was placed. there were. In order to solve this problem, it is conceivable to lower the fixing position of the belt or stretch a plurality of belts, but this is not practical in terms of certainty and cost. For this reason, if it is the method of extending | stretching a net and covering the whole front surface of the mounting space formed with a some upper and lower shelf board, it is not necessary to consider the height and cost of a mounting object, and is realistic. However, since the net itself is made of nylon, it tends to bend, and is particularly noticeable at the center of the net. For this reason, when a relatively small and heavy article is placed, it is expected that the article will fall out of the gap that is bent by pushing out the net.

  The present invention has been made to solve the above-mentioned problems, and a dropped object for preventing an article such as a file or a product placed on a shelf from falling from the shelf when an earthquake occurs. An object of the present invention is to provide a holding object fall prevention net stopper that complements the uncertainty of the fall prevention function caused by the bending of the net.

  In order to solve the above-described problems, a holding device for preventing a dropped article from being dropped according to the present invention includes a holding plate in which at least one stud having a substantially spherical head at a distal end is fixed, and the substantially spherical head. A holding plate having a plurality of upper and lower shelf plates, and a retaining plate having a hole that is formed in a crank shape with a width that does not allow the substantially spherical head to come off. A plurality of shelf plates in the center of the mounting space formed in the front side are fixed in the lateral direction, and a net is stretched over the entire front surface of the mounting space to cover the holding plate. By attaching the net and holding the net, it is possible to suppress the net from being bent and prevent the article placed on the shelf from falling.

  With the stopper for the object fall prevention net of the present invention, a plurality of upper and lower shelf boards can be used to prevent items such as files and products placed on the shelf from falling from the shelf when an earthquake occurs. When a net is stretched and covered over the entire front surface of the mounting space to be formed, the uncertainty of the fall prevention function due to the bending of the net is complemented, and the net is bent and placed on the shelf. There is an effect that it is possible to reliably prevent the dropped article.

  The best mode for carrying out the present invention will be described with reference to the drawings.

  2A and 2B are external views of a holding plate constituting the holding device for preventing a dropped object from being dropped according to the present invention, wherein FIG. 2A is a front view and FIG. 2B is a plan view. As shown in the figure, the holding plate 1 is configured by fixing at least one stud 2b having a substantially spherical head 2a at the tip. Since the holding plate 1 is fixed in the lateral direction of the front surface of the shelf plate as will be described later, it is preferable to apply the double-sided tape 3 to the back surface in advance to improve workability. In addition to the fixing method using the double-sided tape 3, a method using screws or the like may be used. 3A and 3B are external views of the retaining plate constituting the retaining member for the object fall prevention net of the present invention, wherein FIG. 3A is a front view and FIG. 3B is a plan view. As shown in the figure, the retaining plate 4 has a hole 5a into which the substantially spherical head 2a can be inserted, and a flange formed in a crank shape with a width that prevents the substantially spherical head 2a from coming out following the hole 5a. And a hole 5b. As will be described later, the hole 5b has a structure for preventing the retaining plate 4 sandwiching the net from falling off, and the shape and the like are not limited to those illustrated.

  FIG. 4 is a front view of a shelf in which the hold-down device for the object fall prevention net according to the present invention is not mounted. Items such as files and products placed on the shelf are dropped from the shelf when an earthquake occurs. The net 8 is stretched over the entire front surface of the placement space formed by the plurality of upper and lower shelf boards 6 as a placement object fall prevention net for preventing the situation. The bottom side and the top side of the net 8 are reinforced by a tarpaulin belt 10, and the bottom side is fixed with bolts 9 at several locations in the front lateral direction of the shelf 6 at the bottom. Further, the upper side portion is stretched with three one-touch buckles 11 in the front lateral direction of the shelf board 6 further above the upper side portion. The tensioning method using the one-touch buckle 11 is for easily putting the article 12 into and out of the shelf board 6, but other methods may be used without being limited to the method.

  In this state, when an earthquake (particularly an earthquake with severe roll) or the like occurs, the article 12 placed at the center of the net 8 (the chain line indicated by reference A) pushes the net 8 forward and bends. The article 12 falls from the gap.

  FIG. 5 is a front view of a shelf in which the mounting object fall prevention net retainer of the present invention is mounted. When an earthquake occurs, articles such as files and products placed on the shelf fall from the shelf. The net 8 is stretched over the entire front surface of the mounting space formed by the plurality of upper and lower shelf boards 6 to cover the front surface of the shelf as a placement object fall prevention net for preventing A state is shown in which a retaining plate 4 is attached to a plurality of holding plates 1 fixed in the lateral direction of the front surface of the shelf 6 at the center stage of the mounting space and the net 8 is sandwiched.

  FIG. 1 is a diagram showing the procedure for using the mounting object fall prevention net stopper according to the present invention. In (a), when the net 8 is stretched over the entire front surface of the mounting space formed by the plurality of upper and lower shelf boards 6 to cover the front surface of the shelf, the nets of the net 8 are naturally applied to the front face of the holding plate 1. Indicates the state. (B) inserts the hole 5a of the retaining plate 4 into the head 2a at the tip of the stud 2b fixed to the holding plate 1 and attaches the retaining plate 4 along the flange 5b formed in a crank shape. Indicates the state. With this procedure, the net 8 can be sandwiched between the retaining plates 4.

  In the above state, when an earthquake (especially severe earthquake) occurs, the article 12 placed in the central part of the net 8 tries to push the net 8 forward, but there are a plurality of articles in the central part of the net 8. Since the holding plate 4 is attached to the shelf plate 6, the article 12 is prevented from being bent or minimized, and therefore the article 12 can be prevented from falling without generating a gap.

  In addition, the content of the right regarding the shape and structure of the holding plate 1 and the holding plate 4 constituting the holding fixture for the object fall prevention net described above is not limited to the embodiment, and all the functions having the same functions are included.
