Description

  The present invention relates to an overturn prevention device for a vending machine that prevents the vending machine from overturning.

  It is desirable to install vending machines so that they do not fall over in the event of a disaster such as an earthquake. As an installation standard to prevent the vending machine from falling, the “Vending Machine Installation Standard” established by the Japanese Industrial Standards and the “Vending Machine” which is the industry independent standard established by the Japanese Vending Machine Industry Industry to complement it The installation surface, installation method, etc. are stipulated by the “Indoor Installation Standards for Machines”. According to these standards, when installing a vending machine outdoors, as a rule, the method of fixing the vending machine's legs with fixing brackets and post-installed anchors is shown. As a case where it is installed indoors, a method of fixing an iron plate for preventing overturning to a leg part of a vending machine is shown.

  The method of fixing the iron plate for preventing overturning to the legs of the vending machine can be used effectively in places where anchor bolts cannot be installed or in vending machines installed indoors, and can effectively prevent the vending machine from overturning. FIG. 1 shows a conventional fall prevention device using a fall prevention iron plate. The fall prevention device shown in this figure is the upper surface of the installation surface 23 on which the vending machine 21 is installed, and the fall prevention iron plate 24 laid below the front and rear legs 22 of the vending machine 21 and the fall prevention. A fixing bracket 25 is provided for fixing the front and rear legs 22 placed on the upper surface of the iron plate 24 to the toppling prevention iron plate 24. As shown in FIG. 1, in this overturn prevention device, the front and rear legs 22 of the vending machine 21 are fixed to the upper surface of the overturn prevention iron plate 24 with a fixing bracket 25. The toppling prevention iron plate 24 has a total length protruding forward from the front surface of the vending machine 21, and the protruding portion 24A prevents the vending machine 21 from falling forward.

  The fall prevention device of this structure is fixed to all vending machines depending on the installation conditions of the vending machine, because the front and rear legs of the vending machine are fixed to the top surface of the fall prevention iron plate using fixing brackets. Can not. In particular, there is a drawback that the rear legs cannot be connected to the fall-preventing iron plate. For example, when a plurality of vending machines are installed side by side, or when the side surfaces are set close to a wall, the fixing bracket for fixing the rear leg cannot be fixed to the fall-preventing iron plate. This is because it is extremely difficult to insert a tool or the like between vending machines installed without gaps and fix the fixing bracket to the iron plate for preventing overturning. Therefore, in such a case, after fixing the fall prevention iron plate to the four corner legs of the vending machine in a place where it is easy to work in advance, the vending machine is lifted with a hand pallet truck or crane and moved to a predetermined position It is necessary to let For this reason, this overturn prevention device has the disadvantage that it takes much time for these operations and cannot be easily installed.

  In particular, the fall prevention device is installed not only in a newly installed vending machine but also in an existing vending machine, but it cannot be easily installed in such a case. With the existing vending machine lifted, lay an iron plate for tipping under the front and rear legs, and after placing the front and rear legs on it, the front and rear legs are secured with a mounting bracket. It is because it is necessary to fix to an iron plate. In particular, when multiple vending machines are installed side by side, or when the side is set close to the wall, the vending machine is lifted and pulled out by dedicated equipment such as a hand pallet truck and then falls. It is necessary to fix the front and rear legs to the prevention iron plate with fixing brackets, and then return to the original position. For this reason, it takes a lot of work to install this fall prevention device in an existing vending machine.

In order to eliminate such an adverse effect, a fall prevention plate that can be easily attached to the front and rear legs of a vending machine has been developed (see Patent Document 1).
Japanese Patent Laid-Open No. 06-187554

  As shown in FIG. 2, the fall prevention plate described in this gazette has front and rear sides of a landing member 32 in which a hexagonal portion and a landing portion are provided at the lower end of a screw shaft portion 32A screwed into the bottom four corners of the vending machine. The prevention plate body 34 is engaged with the two. The fall prevention plate has two long holes 35 that guide the screw shaft portions 32A of the front and rear landing members 32 in the front-rear direction on both front and rear ends of the prevention plate main body 34. A through hole 36 into which the landing portion of the landing member 32 can be inserted is provided. Further, the fall prevention plate is provided with a concave portion 37 for accommodating the landing portion of the landing member 32 on the lower surface of both the long holes 35. The fall prevention plate of this structure lifts the vending machine, inserts the landing portions of both landing members 32 into the front and rear through holes 36 with the front and rear landing members 32 separated from the installation surface, and then The prevention plate body 34 can be shifted rearward so that the front and rear landing portions can be accommodated in the recesses 37 and connected to the front and rear landing members 32 of the vending machine. Therefore, even if it is an existing vending machine, the fall prevention plate can be connected to the front and rear landing members without being pulled out from the installation location.

  However, the fall prevention plate having this structure is provided with a recess for accommodating the landing portion of the landing member inside the prevention plate main body, so that the structure of the prevention plate main body is complicated and the manufacturing cost is increased. Furthermore, the main body of the prevention plate provided with a recess inside has a drawback that the entire thickness is increased. The overturn prevention plate prevents the vending machine from falling forward by disposing the front end portion so as to protrude forward from the front surface of the vending machine. Therefore, the structure in which the main body of the prevention plate is thick has a problem that the height of the portion protruding forward of the vending machine is high, and it is easy to trip over this portion.

  Furthermore, the biggest drawback of the fall prevention plate of this structure is that the entire vending machine needs to be lifted when installed below the vending machine. In this state, both the front and rear landing members are separated from the installation surface, and the landing portions of the front and rear landing members are inserted and connected to the through-holes opened to the front and rear of the prevention plate main body. Therefore, when connecting the prevention plate main bodies, it is necessary to lift the whole of the vending machine, and this work requires a dedicated tool such as a hand pallet truck, which takes time to install. Furthermore, it takes time and effort to insert both the front and rear landing members from the through holes opened in the front and rear of the prevention plate main body. This is because it is necessary to move the heavy prevention plate main body to an accurate position and insert the landing portion of the landing member from the through hole. In addition, since the fall prevention plate has a long hole provided in the prevention plate main body in the front-rear direction of the vending machine, the landing member is aligned along the opening direction of the long hole when a shake such as an earthquake occurs. The vending machine may move in the front-rear direction due to movement.

  Furthermore, the gazette of Patent Document 1 describes a structure (see FIG. 5) in which a rear elongated hole is extended to the rear end of the prevention plate main body and opened (see FIG. 5). A structure (see FIG. 6) is also described in which a seat plate to be provided is omitted and the landing portion of the landing member is directly seated on the installation surface. By combining these structures, the fall prevention plate can insert the rear landing member into the rear long hole without lifting the rear landing member. The fall prevention plate of this structure can fix the front landing member to the long hole by tightening the nut member screwed into the screw shaft portion of the landing member. However, since the tipping prevention plate having this structure is also inserted into the front landing member through the through hole opened in front of the prevention plate body, this work is troublesome. Also, if the nut material that fixes the front leg to the prevention plate body is loosened, there will be nothing to position and fix the prevention plate body with respect to the leg, so along the long hole that opens in the front-rear direction There is also a drawback that the landing member can move relatively and the prevention plate main body moves back and forth. If this happens, it will be impossible to prevent the vending machine from overturning in the event of an earthquake, which is extremely dangerous.

The present invention has been developed for the purpose of eliminating the above drawbacks. An important object of the present invention is to provide a vending machine overturn prevention device that can reliably prevent a vending machine from overturning in the event of an earthquake while mass-produced at a low cost with an extremely simple structure. is there.

  For example, in the fall prevention device according to claim 1 of the present invention, the base plate can be laid on the installation surface in a state in which only the front is lifted without lifting the back of the vending machine, that is, the posture in which the vending machine is inclined backward. . In general, vending machines are provided with heat-dissipating parts on the back without exception, so that heat is efficiently dissipated in this part, with a gap provided on the back. Therefore, the installed vending machine can be inclined backward by this gap. With the fall prevention device of the present invention, the vending machine can be tilted rearward to float the front leg, and the base plate can be laid very easily below the front leg.

  Furthermore, in the fall prevention device according to claim 1 of the present invention, since the front leg of the vending machine is placed on the upper surface of the front part of the base plate, the leg is fixed to the base plate with the fixing bracket. The front legs can be connected to the base plate very easily without accurately positioning the connection position with the base plate. In addition, since the fall prevention device places the front leg on the upper surface of the base plate, when the vending machine tries to fall forward, this force acts on the base plate via the front leg, and the front leg In other words, the base plate is pushed in the direction of the installation surface. In other words, the fall of the vending machine is prevented by the weight of the vending machine. Therefore, the fall-preventing device having this structure can realize the feature that can easily and easily prevent the vending machine from being overturned while installing the base plate below the vending machine.

  Further, in the fall prevention device according to claim 2 of the present invention, a notch opening is provided on the side edge of the front portion of the base plate, and the front leg is inserted and connected to the notch opening, so that the base plate is laid.

  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment shown below exemplifies the fall prevention device for embodying the technical idea of the present invention, and the present invention does not specify the fall prevention device as the following.

  Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the examples are indicated in the “claims” and “means for solving problems” sections. It is added to the members. However, the members shown in the claims are not limited to the members in the embodiments.

  The fall prevention device for a vending machine according to the present invention connects the front and rear legs of a vending machine, in which bolt-shaped legs are connected to the four corners of the bottom, to a base plate laid on the installation surface on which the vending machine is installed. Prevent vending machines from overturning. Generally, the legs provided at the four corners of the vending machine are level adjusting screws, and the height is adjusted by the amount screwed into the bottom surface of the vending machine. As shown in FIG. 3, the leg that is a level adjusting screw includes a screw portion 2 </ b> A that is screwed into the bottom surface of the vending machine 1, and a support plate that is provided at the lower end of the screw portion 2 </ b> A and supports the load applied to the leg 2. Part 2B. The support plate portion 2B at the lower end has a plate shape perpendicular to the screw portion 2A, and the area of the lower surface is increased to reduce the ground pressure. Further, the leg 2 that is a level adjusting screw includes a prism portion 2C at a boundary portion between the screw portion 2A and the support plate portion 2B in order to rotate the screw portion 2A. The leg 2 having this structure adjusts the height of the four corners on the bottom surface of the vending machine 1 by adjusting the screwing amount of the screw part 2A by turning the prism 2C with a tool such as a spanner. In the illustrated leg 2, the outer shape of the prism 2C is larger than the outer diameter of the screw portion 2A, and the outer shape of the support plate 2B is larger than the outer shape of the prism 2C. Further, in the leg 2 shown in the figure, the outer shape of the prismatic part 2C is a hexagon, and the outer shape of the support plate part 2B is a circle. However, the prism portion can be a polygonal shape other than a hexagon, and the support plate portion can also be a shape other than a circle.

  The toppling prevention device shown in FIGS. 3 to 7 is a first embodiment of the present invention, and includes a base plate 4 laid on the installation surface 3 of the vending machine 1 and a vending machine connected to the base plate 4. 1 and a fixing metal fitting 5 for fixing the front leg 2.

  The base plate 4 is obtained by cutting an iron plate into a predetermined width and length. The base plate 4 is arranged extending in the front-rear direction of the vending machine 1. The length of the base plate 4 is longer than the length from the back surface to the front surface of the vending machine 1 so that the vending machine 1 can be prevented from falling forward. One end of the base plate 4 is located on the back side of the vending machine 1, the rear leg 2 is connected to the end, and the other end is laid on the installation surface 3 so as to protrude forward of the vending machine 1. Is done. The base plate 4 prevents the vending machine 1 from tipping forward by the protruding portion 4A protruding forward. In the base plate 4, the length of the protruding portion 4A can be 0.1 to 1 times, preferably 0.2 to 0.5 times the distance between the legs positioned before and after the vending machine 1. . For example, the vending machine 1 in which the distance between the front and rear legs 2 is 730 mm can effectively prevent the vending machine 1 from tipping forward by setting the protrusion 4A of the base plate 4 to 70 to 500 mm, preferably 150 to 350 mm.

  Further, as will be described later, the base plate 4 can be protruded rearward of the vending machine 1 by adjusting the depth and position of the notch opening 6 provided at the rear end. As shown in FIG. 8, the base plate 4 has a length of the rear protruding portion 4B protruding from the back surface of the vending machine 1 such that the tip of the base plate 4 hits an obstacle such as a wall located on the back side of the vending machine 1. It is possible to make it not touch. The length of the rear protrusion 4B can be, for example, 200 mm or less, preferably 100 mm or less. Thus, the base plate 4 that protrudes rearward has a feature that can support the vending machine 1 more stably.

  The width of the base plate 4 should be sufficient to support the legs 2 of the vending machine 1 and not to bend or break when the force is applied in the direction in which the vending machine 1 falls. Can do. For example, the width of the base plate 4 can be 5 to 40 cm, preferably 10 to 30 cm. However, although mentioned later, the base plate used for the application which supports two vending machines can also be made into the width | variety of 20-60 cm.

  Furthermore, the thickness of the base plate 4 can be 5 to 20 mm, preferably 7 to 15 mm. A thick base plate can effectively prevent bending and breaking when a force is applied in the direction in which the vending machine falls. In addition, since the weight of the entire base plate can be increased, the center of gravity can be lowered to prevent the vending machine from falling over in a state where it is connected to the vending machine. On the contrary, a thin base plate can make it difficult to trip by reducing the step of the front protrusion. Therefore, the thickness of the base plate is set to the above-mentioned range in consideration of these matters.

  The base plate 4 is provided with a notch opening 6 for inserting and connecting the legs 2 of the vending machine 1 at the rear end portion disposed behind the vending machine 1. The notch opening 6 is an opening provided by notching from the outer peripheral edge of the base plate 4 toward the center portion. The base plate 4 shown in the figure has a notch opening 6 having an opening at the rear edge.

  The notch opening 6 in FIG. 6 includes a slit portion 6A provided linearly from the opening edge, and a circular fitting portion 6B provided at the tip of the slit portion 6A. The width (W) of the slit portion 6A is smaller than the diameter (D) of the fitting portion 6B. The cutout opening 6 having this shape has a width (W) of the slit portion 6A slightly larger than the outer diameter of the screw portion 2A and smaller than the minimum outer diameter of the prismatic portion 2C, and is inserted through the screw portion 2A. Although it can, it is set as the width | variety which cannot pass 2 C of prisms. Furthermore, the diameter (D) of the fitting portion 6B is made slightly larger than the maximum outer diameter of the prismatic portion 2C and smaller than the minimum outer diameter of the support plate portion 2B, and the prismatic portion 2C can be inserted. The size cannot pass 2B. The notch opening 6 having this shape is inserted in a state in which the leg 2 is inserted into the notch opening 6 while the screw part 2A is passed through the slit 6A, and the prism 2C is inserted into the fitting part 6B. Are connected to a predetermined position of the base plate 4.

  The depth (L) of the notch opening 6 can be set to a length that allows the leg 2 to be guided to the notch opening 6 of the base plate 4 and reliably connected. However, depending on the installation state of the vending machine 1, there may be a sufficient gap on the back side of the vending machine 1. In such a case, as shown in FIG. 8, the depth of the notch opening 6 is made deeper and the rear leg 2 is positioned and connected to the center side of the base plate 4, thereby making the vending machine 1 more stable. Can be supported. For example, as shown in FIG. 9, the notch opening 6 may have a structure in which a plurality of insertion portions 6B are provided and these are connected by a linear slit portion 6A. The notch opening 6 having this structure allows the screw 2A to pass through the slit 6A until the prism 2C of the leg 2 reaches the insertion portion 6B at a desired position, so that the connecting position of the legs 2 can be easily changed. . The notch opening 6 shown in FIG. 9 is provided with two insertion portions 6B, and these insertion portions 6B are connected by a slit portion 6A. However, as shown by the chain line in FIG. 9, the notch opening 6 may include three insertion portions 6 </ b> B or four or more not illustrated.

  Further, as shown in FIGS. 10 and 11, the base plate 4 can be provided with a recess 7 that is located on the lower surface of the fitting portion 6B and that accommodates the support plate portion 2B of the leg 2. The concave portion 7 can have an outer shape and a depth into which the support plate portion 2B can be inserted. As described above, the base plate 4 having the recess 7 for accommodating the support plate portion 2B on the lower surface can make the lower surface of the support plate portion 2B and the lower surface of the base plate 4 flush with each other in a state where the prismatic portion 2C is inserted into the fitting portion 6B. Therefore, the base plate 4 can be laid in a state where the lower surface of the base plate 4 is in close contact with the installation surface 3. The recessed part 7 shown in the figure is located on the lower surface of the fitting part 6B and is provided in a circular shape concentric with the fitting part 6B. Therefore, the prism 2C can be positioned by the fitting portion 6B, and the support plate 2B can be positioned by the recess 7 so that the leg 2 can be reliably connected to an accurate position. However, although not shown, the concave portion can be provided over the entire lower surface of the notch opening, that is, on the lower surface of the slit portion.

  Furthermore, the base plate 4 shown in FIGS. 10 and 11 has an inclined surface 8 on the lower surface side of the opening edge of the notch opening 6. The notch opening 6 having this structure has an advantage that the screw portion 2A can be smoothly guided to the slit portion 6A by moving the upper surface of the prismatic portion 2C, which is the lower portion of the leg 2, along the inclined surface 8.

  The base plate 4 shown in the above figures has a notch opening 6 at the rear edge. However, the notch opening 6 can also be provided at the side edge of the base plate 4 as shown in FIG. The notch opening 6 opened to the side edge can be provided with a plurality of notch openings 6 separated in the front-rear direction, as indicated by a chain line in the figure. Furthermore, although the notch opening part opened to a side edge is not shown in figure, it can also be set as the structure which provides a some insertion part in the front and back, and connects these with a slit part. The base plate 4 having these structures can also easily change the connecting position of the rear legs 2.

  Furthermore, the base plate 4 shown in FIG. 5 has an elastic plate 9 disposed on the lower surface. The elastic plate 9 is a mat or sheet having elasticity such as a rubber mat or a plastic sheet. The elastic plate 9 brings the base plate 4 into close contact with the installation surface 3 and increases the frictional resistance between the base plate 4 and the installation surface 3 to prevent the base plate 4 from shifting. Further, by disposing the elastic plate 9 on the lower surface of the base plate 4, minute unevenness and steps on the installation surface 3 are absorbed to prevent the base plate 4 from rattling. In the base plate 4 shown in the figure, the elastic plate 9 is fixed to a plurality of locations on the lower surface, but the elastic plate can also be provided on the front surface of the lower surface of the base plate.

  The fixture 5 includes a clamping plate 10 and a connecting screw 11 that couples and fixes the clamping plate 10 to the base plate 4. The fixing metal 5 sandwiches the support plate portion 2B between the sandwiching plate 10 and the base plate 4, and holds the front leg 2 in a predetermined position.

  The sandwiching plate 10 has an opening 12 at one end edge. The opening portion 12 includes a slit portion 12A that allows the screw portion 2A of the leg 2 to pass therethrough, and a fitting portion 12B that fits the rectangular column portion 2C of the leg 2. The sandwiching plate 10 is connected to a predetermined position so that the prism 2 </ b> C is inserted into the insertion portion 6 </ b> B and the leg 2 is not removed from the opening 12. Further, the sandwiching plate 10 is provided with a concave portion 13 in which the support plate portion 2B of the leg 2 is disposed below.
