Description

  The present invention relates to an improvement in a housing structure constituting an automatic vending machine such as an automatic ticket vending machine, an information terminal device, and the like.

Various devices such as a vending machine such as a vending machine, a cash dispenser, and an information terminal device have a configuration in which mechanical parts, electrical parts, electronic parts, and the like are housed in a metal casing.
In these devices, open parts are provided on the front, back, and other parts of the housing for maintenance of each component inside the housing and for entering and leaving tickets, goods, money, etc. And the opening is opened and closed by a door. In general, a front door provided with an operation unit, a display unit, and the like is supported on the front surface of the housing so as to be freely opened and closed.
In addition, when manufacturing a model that performs maintenance by opening the rear open part of the housing, the rear door is pivotally supported on the rear open part so that it can be opened or closed, or the rear panel is screwed to the housing. It is common to attach it detachably.

  FIG. 3 is an exploded perspective view showing an example of a conventional case structure. This case structure 101 is used for, for example, a ticket vending machine, and this case structure 101 has open portions on at least a front surface and a back surface. A housing main body 102 having 103 and 104, a front door 110 pivotally supported to open and close the front opening 103 of the housing main body 102, and a rear opening 104 of the housing main body 102 are detachably fixed. And a rear panel 120. Further, an angle member 105 having an L-shaped cross section is fixed to each of two opposing edges 104 a and 104 a and the upper side 104 b of the back surface opening portion 104 of the housing body 102, and the rear panel 120 is fixed to the angle member 105. Was fixed with screws.

However, the housing main body 102 having the opening portions on the front and back surfaces as described above is a mere cylindrical metal box with the front door 110 and the rear door 120 removed, and the mechanical strength is extremely low. There has been a problem that the case body is distorted and deformed when a heavy unit or the like is incorporated into the case body.
Further, in Patent Document 1, in a lift-use card vending machine installed at a ski resort or the like, in addition to an outer door provided with a sales operation unit that opens and closes the front surface of the housing, an inner side that opens and closes the rear opening portion of the housing. There is disclosed a configuration in which maintenance or the like can be performed from the indoor side by arranging a maintenance door on the (indoor side).
However, even in this conventional example, the strength of the casing is not sufficient, and there is a problem that deformation is caused by the load when a heavy object is supported.

In order to increase the strength of the housing, measures are taken to add welding reinforcement members at appropriate locations in the housing, or to add a reinforcing structure to the front door, rear door, or rear panel. The effect cannot be obtained. In addition, measures to increase the thickness of the housing structural material or to change the basic structural shape itself can be considered, but this increases the design change factor and increases the loss in design work. It tends to be avoided.
JP-A-8-315235

  As described above, in the case structure of conventional mechanical devices, electrical devices, electronic devices, etc., the front door is pivotably supported on the front side of the case where the operator is located, and the rear door is opened and closed at the rear opening. When pivoting freely or fixing the rear panel to the rear open part, the mechanical strength of the chassis itself is not sufficient. There was a problem of deformation.

  The present invention has been made in view of the above, and a housing having an opening portion on the front surface and the back surface, which has a structure that is inherently fragile without significantly modifying the existing housing structure. An object of the present invention is to provide a housing structure capable of sufficiently reinforcing the above.

In order to achieve the above object, an invention according to claim 1 is a housing main body having an opening at least on a front surface and a back surface, a front door that opens and closes the front opening portion of the housing main body, and a rear surface of the housing main body. And a rear panel that is detachably fixed to the open portion, and is a reinforcement having both ends fixed by being passed to two opposing edges of the back open portion of the case main body. The rear panel is fixed to the rear open portion by detachably fixing the rear panel to the reinforcing member.
The reinforcing member exhibits a reinforcing performance that enhances the mechanical strength of the housing body by being fixed across two opposing edges of the back surface opening portion, while utilizing a gap formed between the reinforcing members. It is possible to perform maintenance on the units and parts inside the housing body.

Moreover, not only the reinforcement of the housing is realized by a reinforcing member that can be attached by a simple work equivalent to the mounting work of the angle member used for fixing the rear panel in the conventional housing structure, but also this reinforcement. It also has the function of fixing the rear panel to the member.
The direction in which the reinforcing member is passed can be arbitrarily selected from a horizontal direction, a vertical direction, an oblique direction, and the like. Since the rear panel is configured to be attached to and detached from the reinforcing member, the rear panel may be removed during maintenance. Since the rear panel can be attached and removed by screwing or the like, it is easy to install and remove.

According to a second aspect of the present invention, in the first aspect of the present invention, in the state where the rear panel is detached from the reinforcing member, a gap communicating with the inside of the housing body is formed in a range where the reinforcing member is not located in the rear open portion. It is characterized by being.
Maintenance can be carried out by accessing the internal unit, components, etc. from the gap formed between the reinforcing members or between the reinforcing member and the edge of the rear opening.
A third aspect of the present invention is characterized in that, in the first or second aspect, the reinforcing member comprises a member main body made of a plate material, and a fixing piece in which both longitudinal ends of the member main body are bent.
The structure of the reinforcing member itself is very simple, and the cost that is increased by adding the reinforcing member is small.

According to a fourth aspect of the present invention, in the first, second, or third aspect, the member main body is provided with an opening or a notch.
While maintaining the reinforcing performance of the casing body by the reinforcing member, it is possible to easily perform maintenance of the internal unit and parts using the openings and notches provided in the reinforcing member.

  According to the present invention, the rear panel is detachably fixed to the reinforcing member that is passed between the two opposite edges of the rear open portion of the housing body and fixed at both ends, thereby forming the rear open portion. On the other hand, since the reinforcing structure for fixing the rear panel is adopted, the casing having an opening portion on the front and back surfaces has a structure that is inherently fragile without significantly modifying the existing casing structure. The body can be sufficiently reinforced. Furthermore, maintenance work can be easily performed on the units and components inside the casing body by using a gap formed between the reinforcing members or between the reinforcing member and the edge of the rear opening. In addition, the maintenance function of the reinforcing member can be sufficiently maintained while the maintenance of the unit or the like can be performed using the opening or the notch provided in the reinforcing member.

  In the present invention, the case is reinforced by a reinforcing member that can be attached by a simple operation equivalent to the number of attachments of the angle member that is attached to the edge of the rear open portion in order to fix the rear panel in the conventional case structure. In addition to realizing the above, it is possible to have a function of fixing the rear panel to the reinforcing member. Therefore, the reinforcing function of the casing and the mounting function of the rear panel are realized at the same time by the same number of mounting steps as in the conventional rear panel mounting process.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1 is an exploded perspective view showing a configuration of a casing structure (rear panel closing and fixing structure) according to an embodiment of the present invention. The casing structure 1 has open portions 3 and 4 on the front and back, respectively. The housing main body 2 provided, the front door 10 pivotally supported by the shaft support portion 10a with respect to the front opening portion 3 of the housing main body 2, and the rear opening portion 4 of the housing main body are detachable. And a rear panel 20 to be fixed.

The housing structure 1 is used for, for example, a ticket vending machine, and an operation switch, a display unit, a money slot, a money outlet, and the like (not shown) are provided on the front surface of the front door 10. Illustration of various components and units arranged inside the housing body 2 is omitted.
The characteristic structure of the housing structure 1 includes a housing body 2 having open portions 3 and 4 on at least a front surface and a back surface, and a front shaft that is pivotally supported so as to open and close the front surface opening portion 3 of the housing body 2. In a housing structure that includes a door 10 and a rear panel 20 that is detachably fixed to the back surface opening portion 4 of the housing body 2 with screws or the like, the back surface opening portion 4 of the housing body 2 faces the back panel 20. The reinforcing member 30 is provided between the two end edges 4a and 4a and fixed at both ends 31 by screws, welding or the like. The rear panel 20 is fixed to the back surface opening portion 4 by detachably fixing the rear panel 20 to the reinforcing member 30 using fixing means such as screws.

In a state where the rear panel 20 is detached from the reinforcing member 30, a gap S that communicates with the inside of the housing body is formed in a range where the reinforcing member of the back surface opening portion 4 is not located. In this way, the positional relationship and size of the gap so that maintenance can be performed by accessing the internal unit, components, etc. from the gap S formed between the reinforcing members or between the reinforcing member and the edge of the rear opening. Set.
The reinforcing member 30 is made of sheet metal, and includes a member main body 32 made of a strip-shaped plate material, and a fixing piece 33 formed by bending both longitudinal ends of the member main body 32. A screw hole 32a is provided at an appropriate position of the member main body 32 of the reinforcing member 30, and a screw 25 is detachably fastened to the corresponding screw hole 20a provided on the rear panel 20 side.

  In this example, two reinforcing members 30 having different widths are arranged in parallel at a predetermined interval. However, the width dimension, the number, the arrangement interval, the arrangement position, and the like of the reinforcing members 30 to be used are the same as those of the housing body 2. Various selections can be made according to various conditions such as size, usage, arrangement of internal units, necessity of maintenance, maintenance frequency, and the like. When considering an increase in the strength of the housing body 2, it is preferable to arrange the reinforcing member 30 so that a gap is not formed as much as possible in the rear open portion 4. On the other hand, for units and parts that require frequent maintenance, by placing them inside the gap S between the reinforcing members, an operator can attach or detach a unit or the like from the gap while the rear panel 20 is removed. Make sure that maintenance can be performed easily by inserting jigs and hands. In order to satisfy these two different requirements at the same time, an optimum number of reinforcing members having an optimum width are fixed with an optimum gap S therebetween, taking into consideration various conditions such as the size of the casing.

  Compared to the angle member used in the conventional example shown in FIG. 3, the reinforcing member of the present invention is remarkably effective in reinforcing the casing body in that the reinforcing member of the present invention is extended over the entire width of the rear opening 4. Get higher. In addition, it is possible to fix the reinforcing member 30 in a stretched state between the peripheral portions of the rear open portion by the same amount of work as fixing the conventional angle member to the peripheral portion of the rear open portion of the housing with screws. Become. Furthermore, the reinforcing member of the present invention is characterized in that it has not only a reinforcing function of the housing body but also a function as a fixture for the rear panel.

Note that the direction in which the reinforcing member 30 is passed between the opposing edges of the housing body does not necessarily have to be the horizontal direction as shown in FIG. There is no limitation on the passing direction as long as a sufficient reinforcing function can be exhibited even in any direction other than the horizontal direction, such as a vertical direction or an oblique direction. Further, another reinforcing member may be passed vertically or diagonally so as to intersect with the horizontally extending reinforcing member. When a plurality of reinforcing members are crossed, for example, the reinforcing members may be configured to cross along a diagonal line such as a brace.
In this way, the strength of the housing body is markedly improved by removably fixing the rear panel 20 with screws or the like to the plate-like member body 32 of the reinforcing member 30 that is inserted between the peripheral edges of the rear open portion. On the other hand, the maintenance operation can be performed by removing the rear panel 20 during maintenance using the gap between the reinforcing members.

Next, FIGS. 2A, 2B, and 2C are views showing modifications of the reinforcing member.
The reinforcing member 30 shown in FIG. 2A is the same as the reinforcing member shown in FIG. 1 in that the fixing pieces 33 are bent at both ends 31 of the plate-like member main body 32. A configuration in which reinforcing pieces 34 bent forward are also provided at both upper and lower end edges. By adding the reinforcing piece 34 in this manner, a part of the unit (not shown) can be supported by the reinforcing piece 34. Further, the strength of the casing body can be increased by attaching or fixing the reinforcing piece 34 to the top plate 5 or the bottom plate 6 of the casing body 2.

  Next, the reinforcing member 30 shown in FIG. 2B is formed by forming an opening 35 at an appropriate position of the plate-like member main body 32, and the reinforcing member 30 is provided in the back surface opening portion 4 in order to increase the strength of the housing main body. This is an improved structure for preventing deterioration of the maintenance workability of the internal units and parts due to the reinforcing member becoming an obstacle when the is fixedly arranged. The reinforcing member 30 is provided with an opening 35 at an appropriate position of the member main body 32, thereby facilitating the attaching / detaching operation and other operations of the unit and parts to be maintained while maintaining the reinforcing performance by the reinforcing member 30. It is configured as follows.

  The reinforcing member 30 shown in FIG. 2C is different from the reinforcing member shown in FIG. 2B in that the notch 36 is formed at a position along the lower edge of the member main body 32. The purpose of forming the notched portion 36 is not to lower the maintenance workability for the internal units while maintaining the reinforcing performance by the reinforcing member 30 as in the purpose of providing the opening 35 in the reinforcing member of FIG. It is in. The position where the notch is formed may be a position along the upper edge of the member body.

It is a disassembled perspective view which shows the structure (closing fixing structure of a rear panel) of the housing | casing structure which concerns on one Embodiment of this invention. (A) (b) And (c) is a figure which shows the modification of the reinforcement member which concerns on embodiment of this invention. It is explanatory drawing of a prior art example.
