Description

  The present invention relates to a vertical heavy object, for example, a vertical heavy object such as an indoor-installed vending machine having a plurality of legs on the outer surface of the bottom, an electronic device, etc. The present invention relates to a structure for preventing overturning of mold heavy objects.

  In Patent Document 1, “a fall prevention plate of a plate-like vending machine that is detachably fixed by a screw member 7 to a leg fixing bracket 6 attached to the front and rear legs 2 of the vending machine 1, In the central portion of the prevention plate main body 3, elongated holes 15 and 16 are formed which extend in the longitudinal direction of the main body and guide the screw member 7 of the leg fixing bracket 6 in a slidable manner. A detent mechanism (a downward recess communicating with the bolt through hole) is provided to prevent the member 7 from spinning freely, and the chamfered portion 19 gradually becomes thinner toward the edge around the prevention plate. Is formed (the reference numeral is that of Patent Document 1) ".

  The horizontal guide slot (long hole portion) for the fastener (screw member) 7 described in Patent Document 1 is positioned on the front (one) horizontal guide slot 15 and the line of the horizontal guide slot 15. The horizontal guide slots 16 on the rear side (the other side) are both formed in a straight line with a predetermined interval in the longitudinal direction of one side of the prevention plate body 3. ing.

  By the way, the front and rear leg portions 2 of the vending machine 1 are provided with a pair of left and right long plate-like fall prevention plates, a plurality of leg fixing brackets 6 and a plurality of fixing tools 7, for example, on the basement of the building or the first floor. In the case of fixing (installing) on the floor surface, as types of these leg fixing brackets 6, for example, “E-type leg fixing brackets (described in Patent Document 1)” and “S-type leg fixing brackets” exist. However, in the fall prevention plate described in Patent Document 1, the front and rear horizontal guide slots 15 and 16 are formed linearly along the longitudinal direction of one side of the prevention plate body 3 as described above. It was difficult to use the “S-shaped leg fixing bracket” at a desired angle. Further, when the “S-shaped leg fixing bracket” is positioned in any one of the linear horizontal guide elongated holes 15 and 16, there is a problem that it protrudes from the edge of the long plate-shaped fall prevention plate. Therefore, the fall prevention structure described in Patent Document 1 corresponds only to a predetermined width dimension of the left and right leg portions of the vending machine.

  In addition, the one in Patent Document 1 cannot be fixed at any position regardless of the width dimension of the left and right legs of the vending machine, and the protruding portion of the S-type leg fixing bracket becomes an obstacle. There were drawbacks. Further, in Patent Document 1, the long hole 6c for the screw member 7 of the leg fixing bracket 6 and the straight notch 6a for inserting the leg 2 of the vending machine are arranged in a straight horizontal guide long hole 15 of the prevention plate body 3, 16, it is necessary to fix the E-shaped leg fixing brackets on the front and rear sides of the prevention plate main body 3 respectively. For example, the front E-shaped leg fixing brackets are fixed along the linear horizontal guide slots 15, On the other hand, it was difficult in practice to fix the rear E-shaped leg fixing bracket so as to be orthogonal to the linear horizontal guide slot 16.

  That is, in Patent Document 1, the arrangement of the front and rear E-shaped leg fixing brackets 6 with respect to the prevention plate body 3 is limited to, for example, the direction along the longitudinal direction of the prevention plate body 3 (the same direction). The front and rear E-type leg fixing brackets 6 are attached to the prevention plate body so as to correspond to both the X-axis direction (width direction of the prevention plate body 3) and the Y-axis direction (longitudinal direction of the prevention plate body 3) generated in the event of an earthquake. There was a disadvantage that it could not be disposed on 3.

  Further, in Patent Document 2, “a plurality of screw holes for fixing tools (screw members) are provided at equal intervals in the longitudinal direction at both end portions (including portions near the center portion) of the center portion of the prevention plate main body. "Matters to be drilled" are disclosed.

In this Patent Document 2, as in the present invention, the front and rear E-shaped leg fixing brackets 6 are combined with each other so that the directions of the front and rear E-shaped leg fixing brackets 6 are in the X-axis direction and the Y-axis direction. 6 is arranged in the X-axis direction, with an S-shaped leg fixing bracket on the rear side, and a straight notch for inserting the leg of the vending machine in the Y-axis direction, and a prevention plate There is no description of the idea of disposing so as not to protrude from the periphery of the screw, and the screw hole for the fixing tool (screw member) is also disclosed in Patent Document 1, as in the case of Patent Document 1. 1 has a problem similar to that of Patent Document 1, since it is dotted in a straight line along the longitudinal direction of one side of the prevention plate main body.

  The problem to be solved by the invention is first to solve the problems of Patent Document 1 and Patent Document 2, particularly the problem that the width dimensions of the left and right legs of the vending machine are limited, for example. It is to propose a structure for preventing the fall of a vertical heavy article that can be stably fixed regardless of the width dimension of the left and right legs of the vending machine.

Next, when E-shaped leg fixing brackets (fixing brackets of the same form) are arranged at the front and rear, an E-shaped leg is provided for one horizontal guide slot having an intersecting line portion communicating with the linear portion. The fixing metal fitting can be disposed in the X-axis direction (the width direction of the fall prevention plate) of the long plate-like fall prevention plate. In other words, it is possible to arrange the fixtures of the same form in combination in two directions.
Further, for one horizontal guide slot having an intersecting line portion communicating with the straight portion, the so-called S-type leg fixing bracket is selectively attached to the leg of the vending machine without being bound to the E-type leg fixing bracket. It is also possible to dispose the linear notch for inserting part in the Y-axis direction so as not to protrude from the edge of the fall prevention plate.

  The vertical heavy load fall prevention structure of the present invention is a long plate-shaped fall prevention structure with the front and rear legs of the vertical heavy load on the same line with the front horizontal guide slot and the rear horizontal guide slot. A plate, a leg fixing bracket that is positioned on the fall prevention plate with respect to the horizontal guide slot, and a fall of a vertical heavy object that is fixed indoors via a fixing tool that fixes the leg fixing bracket on the fall prevention plate In the prevention structure, at least one horizontal guide slot of the horizontal guide slot includes a straight line portion having a start end a and a terminal end b, and a cross line portion communicating with the straight line portion starting from the end point b. When the vertical heavy object is installed, the fixing bolt of the fixing tool is located between the end b corresponding to the start end of the cross line portion and the end c of the cross line portion with respect to the one horizontal guide slot. It is located in.

  In the above configuration, one horizontal guide slot 5 is formed in the vicinity of the corner of the rear end portion of the long plate-shaped fall prevention plate, and the end c of the cross line portion 5b is the start end a or the end end of the straight portion 5a. It is located inside b (the other side of the long plate-like fall prevention plate). Also, an E-type leg fixing bracket in which a straight notch for inserting a leg portion of a vertical heavy article is oriented in the width direction (X-axis direction) of the fall prevention plate with respect to one horizontal guide elongated hole, or the leg S-shaped leg fixing brackets in which the straight cutouts for inserting the parts are oriented in the front-rear direction (Y-axis direction) of the fall prevention plate are selectively provided. It is characterized by not protruding from. As an arrangement mode of the fixing bracket, an E-type leg fixing bracket is arranged in the X-axis direction perpendicular to the front-rear direction of the long plate-shaped anti-tip plate in the horizontal guide slot on the front side. In one horizontal guide slot having an intersecting line portion communicating with the straight portion, the S-shaped leg fixing bracket has a long plate shape so that the straight notch for inserting the leg portion is oriented in the Y-axis direction. It is arrange | positioned so that it may not protrude from the edge of a fall prevention board.

(A) When E-shaped leg fixing brackets of the same form are arranged before and after, the X-axis direction (width direction of the fall prevention plate) and the Y-axis direction (longitudinal direction of the fall prevention plate) generated in the event of an earthquake In order to correspond to these two directions, an E-type leg fixing bracket can be arranged in the X-axis direction of the fall prevention plate for one horizontal guide slot having an intersecting line portion communicating with the straight portion.
(B) When the front and rear E-shaped leg fixing brackets and S-shaped leg fixing brackets are used in combination, the horizontal guide elongated hole having an intersecting line portion communicating with the straight portion is used. Therefore, without sticking to the E-type leg fixing bracket, the so-called S-type leg fixing bracket is selectively directed so that the straight notch for inserting the leg portion of the vending machine is oriented in the Y-axis direction and to prevent overturning. It can also arrange | position so that it may not protrude from the edge of a board.
(C) Accordingly, in the present invention, not only the form is the same, but also different forms of leg fixing brackets (for example, E-type leg fixing brackets and S-type leg fixing brackets) are freely taken into consideration while considering the installation location of the vending machine. The combination can improve the earthquake resistance.
(D) When an S-type leg fixing bracket is selected for one horizontal guide slot on the rear side of the fall-preventing plate, the S-type leg fixing bracket is fixed to the fall-preventing plate in advance and then the leg portion of the vending machine. Can be slid into the straight notch for inserting the leg of the S-shaped leg fixing bracket, so that the vending machine can be installed so as to face the wall surface in the room. Therefore, the installation work efficiency can be improved.
(E) In the case of the embodiment in which the S-shaped leg fixing bracket is arranged so as not to protrude from the edge of the long plate-like fall prevention plate, the S-type leg fixing metal fitting is in close contact with one side 1a of the long plate-like fall prevention plate 1. Thus, since other long plate-like fall prevention plates can be arranged, indoor installation space can be effectively utilized.

  In particular, as shown in FIG. 9, one horizontal guide slot 5 is formed in the vicinity of the corner of the rear end portion 3 of the long plate-shaped fall prevention plate 1, and the end c of the intersection line portion 5b is a straight portion 5a. Is located on the inner side (the other side of the long plate-like overturn prevention plate) of the start end a or the end b thereof, and the fingertip-like hook portion 16 of the S-type leg fixing bracket is eaten by one side 1a of the overturn prevention plate 1. In the case of the embodiment in which the fixing bolt 7a of the fixing tool 7 is located between the terminal end b corresponding to the start end of the crossing line portion and the terminal end c of the crossing line portion in such a state that it does not come out. The pair of long plate-like fall prevention plates 1 and 1 can be laid in accordance with the width of the vending machine, for example, and the long plate-like fall prevention plate 1 can be in contact with one side 1a. It is possible to install a long plate-shaped fall prevention plate (not shown) of It can be utilized to.

  With reference to FIGS. 1 to 10, the structure for preventing the falling of a vertical heavy article of the present invention will be described. FIG. 1 is a schematic explanatory view from a plan view, and a vertical heavy object (for example, a vending machine) 21 is indicated by a virtual line. The fall prevention structure is a symmetrical plate-like fall prevention plate and a leg fixing bracket because they have the same technical idea about the article, so here we will explain on the basis of the left fall prevention structure, and the same components on the right side are the same Reference numerals are assigned and explanations thereof are omitted.

  In the background art, as described with reference to Patent Document 1, for example, the fall prevention structure of the vending machine 21 includes the front and rear leg portions 22 of the vending machine and the left and right long plate-like fall prevention plates 1. The front and rear leg fixing brackets (6, 6A) and a plurality of fixing tools 7 are used for fixing.

  Therefore, the structure for preventing the fall of the vertical heavy object 21 according to the present invention is as follows: “The front and rear leg portions 22 of the vertical heavy object 21 are placed on the same line with the front horizontal guide slot and the rear horizontal guide slot. A long plate-like anti-tip plate, a leg fixing bracket positioned on the long plate-like anti-tip plate with reference to the horizontal guide slot, and a fixing tool for fixing the leg fixing metal plate on the anti-tip plate To be fixed indoors (configuration) ”.

  Now, in FIG. 1, the E-shaped leg fixing brackets 6 and 6 having the same configuration are placed in different directions (dual directions) in the front horizontal guide slot 4 and the rear horizontal guide slot 5 of the long plate-shaped fall prevention plate 1. An example of the arrangement is shown in FIG.

  That is, when the E-shaped leg fixing brackets 6 and 6 having the same form are disposed in the horizontal guide slots 4 and 5 on the front and rear of the upper surface of the long plate-shaped fall prevention plate 1, the X-axis direction generated in the event of an earthquake One horizontal guide length on the rear side having an intersecting line portion 5b communicating with the straight portion 5a so as to correspond to both directions (the width direction of the fall prevention plate) and the Y-axis direction (front and rear and longitudinal directions of the fall prevention plate). For the hole 5, one E-shaped leg fixing bracket 6 is arranged in the X-axis direction of the anti-tip plate with the leg insertion straight cutout 11 facing the one side 1 a side of the anti-tip plate 1. Set up.

  First, the configuration of the long plate-like overturn prevention plate 1 will be described. The long plate-like overturn prevention plate 1 is formed in a long shape by a steel plate material or the like, and the tip portion 2 thereof is chamfered so as to gradually become thin in a U shape in a plan view toward the end edge. The chamfered front end portion 2 to the rear end portion 3 have the same width, and a portion near the front end portion 2 has one side 1a in the longitudinal direction of the fall prevention plate 1 as in Patent Document 1 (prior art). A straight horizontal guide slot (herein referred to as “first guide slot”) 4 is formed so as to extend along the line. Only one “first guide slot 4” is shown in the drawing for convenience of explanation, but “one more (two in total)” may be provided on the same line. The rear end portion 3 is formed with one horizontal guide slot (herein referred to as “second guide slot”) 5, and the second guide slot 5 is the first guide slot. 4 has a straight line part 5a located on the same line as the line 4 and an intersecting line part 5b communicating with the straight line part 5a.

  Here, with reference to the plan view of FIG. 3, the configuration of one horizontal guide slot 5 will be described. The second guide slot 5 includes a straight portion 5 a having a start end a and an end b, and the end b. And the end c of the cross-line portion 5b is defined as the inner end (long plate-like fall prevention plate) with reference to the start end a of the straight-line portion 5a or the end b thereof. The other side 1b side).

  In the present embodiment, one horizontal guide slot 5 has a “boomerang shape” or “ku” shape in appearance. When the vertical heavy object 21 is installed, at least “E-shaped leg fixing bracket 6 having an engagement hole for the fixing bolt 7 a of the fixing tool 7” or “fixing tool 7” with respect to the second guide long hole 5. Any of the S-shaped leg fixing brackets 6A having hook portions for the fixing bolts 7a "is selectively positioned, and the selected leg fixing brackets (6, 6A) are formed into a long plate shape via the fixing tool 7. Fixed on the fall prevention plate. These leg fixing brackets (6, 6A) can be used in “two directions”.

  Thus, the first guide slot 4 and the second guide slot 5 are shown in FIG. 5 (rear surface), FIG. 6 (section of the first guide slot 4) and FIG. 7 (section of the second guide slot 5). As shown in FIG. 5, the corner portion of the relatively small rectangular bolt head is formed in a stepped shape.

  In addition, the first guide elongated hole 4 and the second guide elongated hole 5 are communicated with an unnumbered lower opening groove having a large width and the lower opening groove so that the fixing bolt 7a constituting the fixing tool 7 does not rotate. And an unnumbered upper opening groove having a width narrower than the width of the lower opening groove.

  Next, with reference to FIG. 8, the structure of the E-type leg fixing bracket 6 which is an example of the options of the leg fixing bracket will be briefly described. The E-type leg fixing bracket 6 is substantially the same as Patent Document 1 (prior art). The E-shaped leg fixing bracket 6 is used to connect the leg portion 22 of the vending machine 21 placed on the upper surface of the long plate-shaped fall prevention plate 1 to the fall prevention plate 1 in a locked state. It is a rectangular member made of steel or the like in appearance.

  In other words, the E-shaped leg fixing bracket 6 has a long plate-like upper wall portion 6a and a lower end plate portion 6b on the lower surface side continuous with the periphery of the upper wall portion. An adjustment long hole 10 through which the fixing bolt 7a of the fixing tool 7 passes is formed in the length direction. Further, a predetermined amount of a straight notch portion 11 for inserting a leg portion is formed from the central portion on the other end side with a predetermined interval with respect to the adjustment long hole 10.

  Therefore, the “E-shaped leg fixing bracket 6” here is for inserting a leg part for inserting the through hole (for example, the adjustment long hole 10) for the fixing bolt 7a of the fixing tool 7 and the leg part 22 of the vending machine 21. It has a straight notch 11 and is fixed to the upper surface of the long plate-shaped tipping prevention plate 1 with fixing members 7 (fixing bolts 7a and nuts 7b), and its external appearance is associated with an associative and functional impression. It means the member. In addition, since the detailed matter of the E-type leg fixing bracket 6 is obvious to those skilled in the art, the detailed description thereof is omitted.

  Finally, as shown in FIGS. 2 and 5, the plurality of fixing tools 7 include a fixing bolt 7 a and a nut 7 b that is screwed to the fixing bolt 7 a. In this embodiment, the first guide described above is used. With respect to the long hole 4 and the second guide long hole 5, the fixing bolt 7a is passed through each guide long hole with its head positioned downward and engaged with the lower opening groove. The nut 7b is screwed into the screw portion.

  By the way, when installing the vending machine 21 indoors, of course, first, the installation location of the vending machine 21, the distance between the left and right long plate-like fall prevention plates 1, 1 at the installation location, and the length The position of the leg portion 21 with respect to the plate-like fall prevention plate is determined, and the fixing bolt 7a is passed through the guide long holes 4 and 5 of the fall prevention plates 1 and 1 from below in advance.

  Next, as shown in FIG. 1, if the left and right long plate-shaped fall prevention plates 1 are installed on the floor surface with a predetermined interval, the measured positions on the upper surfaces of the left and right long plate-like fall prevention plates 1 ( The vending machine 21 is appropriately placed so that the leg portion 22 is positioned at the point). At this time, the front and rear legs 22 are positioned in the vicinity of the first guide slot 4 and in the vicinity of the second guide slot 5.

  If the front and rear leg portions 22 are positioned at the measured positions, as shown in FIG. 1, the front horizontal guide slot 4 has one E-shaped leg fixing bracket 6 with a straight notch for inserting the leg portions. The portion 11 is adjusted and disposed so as to be oriented in the longitudinal direction (Y-axis direction) of the long plate-shaped anti-tip plate. On the other hand, one horizontal guide slot 5 on the rear side has other E-shaped legs. The fixing bracket 6 protrudes from the edge of the long plate-shaped fall prevention plate so that the straight cutout portion 11 for inserting the leg portion is oriented in the width direction (X-axis direction) of the long plate-shaped fall prevention plate. It is arranged so that there is no.

  A total of four E-shaped leg fixing brackets 6 in which the front and rear legs Z are connected to each other by screwing nuts 7b to the fixing bolts 7a passing through the guide long holes 4 and 5, respectively. It is fixed to the upper surface of the plate-shaped fall prevention plate 1. At this time, since the straight E-shaped leg fixing bracket 6 on the rear side has the straight notch portion 11 for inserting the leg portion directed to one side 1a in the longitudinal direction, the fixing bolt 7a of the fixing tool 7 is provided with the second guide. It is located at the intersection 5 b of the long hole 5.

  In addition, the leg 22 on the rear side of the vending machine 21 is located on the line of the first guide slot 4, whereas the fixing bolt 7a is located on the inner side. .

  In each explanatory drawing of the present invention, one horizontal guide slot 5 on the rear side has a "boomerang shape" or a "<" shape in appearance. Of course, the shape is limited to this shape. Instead, the intersecting line portion 5b can be set at an arbitrary angle within a range not departing from the purpose of the invention. One horizontal guide slot 5 is preferably formed in the vicinity of the corner of the rear end portion of the long plate-shaped fall prevention plate, and the end c of the intersecting line portion 5b is from the start end a or the end b of the straight portion 5a. Is also located on the inner side (the other side of the long plate-like fall prevention plate), but is not necessarily formed near the corner of the rear end.

  Next, FIG. 9 is an explanatory view similar to FIG. In FIG. 9, the E-type leg fixing bracket 6 and the S-type leg fixing bracket 6A are used in combination. This S-type leg fixing bracket 6A is generally stronger than the E-type leg fixing bracket 6 and considers the installation location of the vending machine (workability when installing the vending machine so as to be close to the wall surface). In this case, instead of the E-type leg fixing bracket 6 instead of the E-type leg fixing bracket 6, an S-type leg fixing bracket 6 </ b> A can be selectively employed on the rear side of the long plate-shaped fall prevention plate 1 for reasons such as ease of installation work.

  FIG. 10 shows an example of an S-shaped leg fixing bracket 6 </ b> A having a hook portion for the fixing bolt 7 a of the fixing tool 7. The main differences from the E-type leg fixing bracket 6 will be described. The S-type leg fixing bracket 6A includes a wide base portion 15 having an adjustment slot 10A for the fixing bolt 7a and one end of the wide base portion 15. A hook portion 16 that extends as if a finger is bent inward from an edge portion, and an S-shaped leg fixing bracket 6A is inserted into the intersecting line portion 5b of the second guide slot 5 with the fixing bolt 7a inserted therein. The finger-like hook portion 16 does not protrude from the edge of the long plate-shaped fall prevention plate 1 when fixed on the plate-like fall prevention plate 1.

  Therefore, the “S-shaped leg fixing bracket” here is a wide base portion 15 having an adjustment long hole 10A for the fixing bolt 7a, and a finger bent inward from one edge of the wide base portion 15. It refers to a member having an extending hook portion 16.

  Referring to FIG. 9, the usage of the fixing bracket will be described. In the front horizontal guide slot (first guide slot) 4, the E-shaped leg fixing bracket 6 is orthogonal to the long plate-shaped fall prevention plate 1. On the other hand, one horizontal guide slot (second guide slot) 5 having an intersecting line portion 5b communicating with the straight line portion 5a on the rear side has an S-shaped leg fixing bracket 6A. Are arranged so that the straight cutout 11A for inserting the leg portion is oriented in the Y-axis direction and does not protrude from the edge of the long plate-shaped fall prevention plate 1.

  By the way, when the S-type leg fixing bracket 6A is adopted, the S-type leg fixing bracket 6A is placed on the tipping prevention plate 1 via the fixing tool 7 before the vending machine 21 is placed on the tipping prevention plate 1. After that, the leg portion 22 of the vending machine 21 is connected so as to be slid into the straight notch portion 11A for inserting the leg portion of the S-type leg fixing bracket 6A.

  Accordingly, the present invention considers the installation environment of the vending machine 21 such as the necessity to install it close to the wall surface, and not only the form is the same, but also different forms of leg fixing brackets (for example, E-type leg fixing brackets). And S-type leg fixing brackets) can be freely combined to improve earthquake resistance.

  The present invention is used for installation companies such as vending machines.
