Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a prefabricated storage that opens and closes an opening provided in a front surface of a heat insulating housing constituting a prefabricated refrigerator, a freezer, etc. by a sliding door, and in particular, the sliding door swings toward the front panel side of the heat insulating housing when sliding. The present invention relates to a prefabricated storage that can be prevented.
[0002]
[Prior art]
Conventionally, various prefabricated storages have been proposed in which a sliding door is disposed in front of an opening formed in a storage such as a prefabricated large refrigerator or freezer, and the opening is opened and closed through the sliding door. .
[0003]
For example, in the storage described in Japanese Utility Model Publication No. 63-1169, Japanese Utility Model Application Laid-Open No. 2-55079, and Japanese Patent Application Laid-Open No. 11-50730, a roller is rotatably supported at the upper end portion of the slide door and the front surface of the lower end. An inclined member having an inclined surface is provided, and the roller is movably suspended on a rail disposed above the opening provided in the storage body, and the inclined member is provided on the installation floor when the sliding door is closed. It is comprised so that it may contact | abut to the laid roller.
[0004]
In these storages, when the sliding door is closed, the inclined member provided on the lower front surface of the sliding door and the roller on the installation floor come into contact with each other and the sliding door is pressed to the front side of the opening. The packing provided on the back surface side of the opening and the front side periphery of the opening are brought into close contact with each other, and the airtightness in the storage is maintained. When the sliding door is opened, the roller at the upper end is guided and moved along the rail to open the opening.
[0005]
[Problems to be solved by the invention]
By the way, in the conventional storage, when the sliding door is opened, the roller at the upper end of the sliding door moves while being guided through the rail at the upper part of the opening of the storage body, but the sliding door moves in this way. During this time, there is no configuration that prevents the sliding door from swinging in the front-rear direction (perpendicular to the sliding direction).
[0006]
At this time, the upper part of the slide door is restricted from swinging in the front-rear direction based on the loose fitting relationship between the roller and the rail, but the lower part of the slide door is restricted in the front-rear direction. Since the configuration does not exist, there is a possibility that the lower part of the slide door may swing in the front-rear direction during the opening / closing operation. In particular, a large sliding door is used in the prefabricated storage in accordance with its large size, and the swinging width at the lower part is considerably large.
[0007]
If the lower part of the sliding door swings in this way, it will be difficult to smoothly open and close it, and the lower part of the sliding door may collide with the front wall of the storage. The front wall and the sliding door will be damaged or broken.
[0008]
The present invention has been made in order to solve the above-mentioned conventional problems, and can prevent the sliding door from swinging to the front panel side of the heat-insulating housing during the sliding, so that the front panel and the sliding door are damaged. An object of the present invention is to provide a prefabricated storage that can smoothly slide the sliding door without being damaged.
[0009]
[Means for Solving the Problems]
In order to achieve the object, a prefabricated storage according to claim 1 is slidably arranged in front of an opening provided in a front panel constituting a heat-insulating housing, and has a sliding door that opens and closes the opening. In the storage, a rubber member provided in the vicinity of the lower end on the back surface side of the slide door, closing the space between the lower end of the slide door and the floor surface of the floor panel constituting the heat insulating housing, and the rubber member on the back surface of the slide door to face disposed mounting and the mounting plate, the plate surface of the mounting plate to the front surface of the front panel, and abuts against the rear surface of the sliding door while the slide door is slid, rotated according to the sliding of the sliding door And a roller member that is pivotally supported and formed of an elastic material .
[0010]
In the prefabricated storehouse according to claim 1 having the above-described configuration, a roller member that can come into contact with the back surface of the sliding door while the sliding door is sliding is disposed on the front surface of the front panel that constitutes the heat insulating casing. Therefore, even when the slide door swings toward the front panel when the slide door is opened and closed, the back surface of the slide door is in contact with the roller member . As a result, the sliding door and the front panel do not collide, and therefore the sliding operation of the sliding door can be performed smoothly without the front panel and the sliding door being damaged or broken.
[0011]
Further, in the prefabricated storehouse according to claim 1, the roller member is pivotally supported so as to rotate according to the slide of the slide door, and is formed of an elastic material . That is, since the roller member is rotated in response to the opening / closing slide operation of the slide door, the opening / closing operation of the slide door can be performed extremely smoothly.
Further, the prefabricated storage of claim 1 is provided in the vicinity of the lower end on the back surface side of the slide door, and the rubber member that closes between the lower end of the slide door and the floor surface of the floor panel constituting the heat insulating housing, An attachment plate for attaching a rubber member to the back surface of the sliding door is provided, and the roller member is disposed to face the plate surface of the attachment plate . Here, the roller member is disposed so as to face the plate surface of the mounting plate that attaches a rubber member that closes between the lower end of the slide door and the floor surface of the floor panel constituting the heat insulating housing to the back surface of the slide door. Therefore, the roller member rotates while contacting the plate surface of the mounting plate when the sliding door is opened and closed. Therefore, the roller member does not directly contact the back surface of the slide door, and even when the outer body of the slide door is formed of a thin plate, the outer body can be prevented from being damaged or deformed.
[0012]
Furthermore, the prefabricated storehouse according to claim 2 is provided with an opening frame member that is disposed at an edge of the opening portion and has a protection portion that is opposed to the back surface of the slide door in the prefabricated storehouse according to claim 1 , The roller member is characterized in that it protrudes more toward the slide door than the protective part of the opening frame member. In the prefabricated storehouse according to claim 2 , there is a protective portion facing the rear surface of the sliding door at the edge of the opening for the purpose of protecting the opening edge and maintaining airtightness between the sliding door and the front panel when closed. Even when the formed opening frame member is disposed, the roller member protrudes closer to the slide door than the protective part of the opening frame member, so that when the sliding door is opened and closed, the back surface of the sliding door and the opening frame member Collision with the protection part is reliably prevented. As a result, it is possible to prevent the slide door and the opening frame member from being damaged or broken.

[0020]
A metal protection plate 11 is fixed to the front surface of the lower end of each slide door 5 through screws 12 over the entire width direction of the slide door 5. As shown in FIG. 4, the protection plate 11 includes an inclined portion 11 </ b> A that is gradually inclined from a substantially central position in the width direction of each slide door 5 toward the front side (lower side in FIG. 4), and an inclined portion. A bent portion 11B which is continuous with 11A and slightly bent in a direction opposite to the inclined portion 11A is integrally formed. Furthermore, the end portion (right end portion in FIG. 4) of the sliding door 5 is made of hard rubber having a shape that is in close contact with the corner portion and supports the connecting portion between the inclined portion 11A and the bent portion 11B from the back side. The block member 19 is attached via a screw (not shown). As will be described later, when the bent portion 11B and the roller 15 come into contact with each other when the slide door 5 is closed, the block member 19 causes plastic deformation and destruction of the bent portion 11B and the inclined portion 11A by its elastic force. In addition, based on the fact that the bent portion 11 </ b> B is pressed through the roller 15, the effect of sealing the opening 4 by the slide door 5 is exhibited.
[0021]
Further, as shown in FIGS. 1 and 2, two roller support members 13 are fixed on the installation floor of the prefab storage 1, and the support shaft 14 provided on the roller support member 13 has A roller 15 that can contact the protective plate 11 of each slide door 5 is rotatably supported.
[0022]
Two bottom courses 17 are formed on the bottom plate 16 of the roller support member 13, and the roller support member 13 is fixed to the installation floor via bolts 18 that are fastened to the respective long courses 17. The position (contact state) of the roller 15 with respect to the protection plate 11 of each slide door 5 can be adjusted by appropriately changing and adjusting the relative position of the bolt 18 in each length course 17.
[0023]
Further, as shown in FIG. 1, each roller support member 13 is installed at the lower left position of the left slide door 5 and the lower right position of the right slide door 5.
[0024]
As shown in FIG. 4, a soft rubber packing member 20 is attached to the entire back surface of the slide door 5 in the height direction on the back side at the end portion (right end portion in FIG. 4). The packing member 20 is in contact with an opening frame member 21 (described later) that is attached over the entire inside of the opening 4 when the opening 4 is closed by each slide door 5, and maintains the airtightness in the storage 1. It is.
[0025]
As shown in FIG. 3, a rubber mounting member 22 is arranged in the vicinity of the lower end on the back side of each sliding door 5 inside the prefabricated storage 1. The rubber mounting member 22 has the rubber plate 23 arranged around the wooden spacer plate W so that the rubber plate 23 hangs down by a predetermined length from both sides of the wooden spacer plate W (see FIG. 5). The rubber plate 23 is fitted together with the wooden spacer plate W in a mounting plate 24 formed into a box shape by sheet metal processing. The rubber mounting member 22 configured in this manner is fastened and fixed to the lower end portion of the slide door 5 via a countersunk screw 25 whose head does not protrude.
[0026]
Here, the rubber plate 23 suspended downward by a predetermined length performs an action of closing the space between the lower end of the slide door 5 and the floor surface 26, so that cold air leaks out from the inside of the prefabricated storage 1. To prevent. Further, since the wooden spacer plate W and the rubber plate 23 are covered by the mounting plate 24, they are not exposed to the outside, the appearance is good, and the corrosion resistance of the wooden spacer plate W is also improved.
[0027]
As shown in FIG. 4 and FIG. 3, an opening frame member 21 is disposed over the entire circumference of the inner edge of the front panel 3 that defines the opening 4 of the heat insulating housing 2. In 21, a protection part 27 is formed integrally with the rear surface of the slide door 5. Here, the opening frame member 21 is disposed to protect the edge portion of the opening 4, and the protection portion 27 is in close contact with the packing member 20 when the slide door 5 is closed. The airtightness between the slide door 5 and the front panel 3 is maintained.
[0028]
A so-called caster 28 is disposed on the front side of the front panel 3 (the lower side in FIG. 4). The caster 28 is rotatably supported by a metal support member 29 and is made of a rubber elastic material. It has a roller 30 formed. As shown in FIG. 4, the roller 30 of the caster 28 is disposed so as to protrude toward the back side of the sliding door 5 with respect to the protection portion 27 of the opening frame member 21, and the plate surface of the mounting plate 24 described above. It is arranged so as to face and contact 24A.
[0029]
Here, since the roller 30 of the caster 28 is disposed so as to protrude to the back surface side of the slide door 5 with respect to the protection portion 27 of the opening frame member 21, the slide 30 slides when the slide door 5 is opened and closed. Even when the door 5 swings toward the front panel 3 side (upper side in FIG. 4), the roller 30 comes into contact with the plate surface 24 </ b> A of the mounting plate 24. Thus, the sliding door 5 and the front panel 3 do not collide, and therefore the sliding operation of the sliding door 5 can be performed smoothly without the front panel 3 and the sliding door 5 being damaged or broken.
[0030]
Further, when the slide door 5 is opened and closed, the roller 30 moves while rotating along the plate surface 24A of the mounting plate 24, so that the slide door 5 can be opened and closed very smoothly. .
[0031]
Furthermore, the opening which has the protection part 27 in the inner edge of the opening part 4 for the purpose of protection of the edge of the opening part 4 and protection of the airtightness between the sliding door 5 and the front panel 3 when the opening part 4 is closed. Even when the frame member 21 is provided, the roller 30 is arranged so as to protrude to the back side of the sliding door 5 with respect to the protection portion 27 of the opening frame member 21, so that it slides when the sliding door 5 is opened and closed. Collision between the rear surface of the door 5 and the protective portion 27 of the opening frame member 21 can be reliably prevented. Therefore, it is possible to prevent the slide door 5 and the opening frame member 21 from being damaged or broken.
[0032]
Further, when the sliding door 5 is opened and closed, the roller 30 rotates while being in contact with the plate surface 24 </ b> A of the mounting plate 24, so that the roller 30 does not directly contact the back surface of the sliding door 5 and the outside of the sliding door 5. Even when the main body is formed of a thin plate, the outer main body can be prevented from being damaged or deformed. Further, since the rubber mounting member 22 is fastened and fixed to the lower end portion of the slide door 5 via a countersunk screw 25 whose head does not protrude, the countersunk screw is obstructed when the roller 30 contacts the plate surface 24A. In addition, since the roller 30 smoothly rotates on the plate surface 24A, the sliding operation of the sliding door 5 can be performed silently.
[0033]
In the above configuration, as shown in FIG. 1, in the state where each sliding door 5 closes the opening 4, the roller 15 of the roller support member 13 fixed on the installation floor of the prefab storage 1 is a protective plate. 11, the sliding door 5 is pressed toward the front side of the front panel 3, and the packing member 20 is in close contact with the protective portion 27 of the opening frame member 21. Therefore, in such a closed state, good airtightness is maintained between the interior of the prefabricated storage 1 and the slide door 5.
[0034]
When the sliding door 5 is slid in the direction of arrow B (see FIGS. 1 and 4) and the opening operation is started, the roller 15 comes off the bent portion 11B and comes into contact with the inclined portion 11A. Separate. Correspondingly, the packing member 20 is separated from the protective portion 27. At this time, the roller 30 of the caster 28 in the front panel 3 rotates while contacting the plate surface 24 </ b> A of the mounting plate 24.
[0035]
Further, when the sliding door 5 is opened, the packing member 20 gets over the roller 30. At this time, the packing member 20 is made of soft rubber, and the roller 30 rotates. There is no obstacle to getting over 30. Then, the slide door 5 is slid to its open position, and the opening 4 is completely opened. Note that, when the sliding door 5 is closed, the reverse operation is performed.
[0036]
Note that the gist of the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the gist of the present invention.
[0037]
For example, in the above-described embodiment, the roller that always contacts the plate surface 24A of the mounting plate 24 of the rubber mounting member 22 provided on the slide door 5 on the front side of the front panel 3 and rotates according to the sliding operation of the slide door 5. Although the caster 28 having 30 is attached, the caster 28 is not limited thereto. For example, an elastic member made of an elastic material such as rubber is attached so as to protrude from the protective portion 27 of the opening frame member 21 toward the slide door 5 and to come into contact with the plate surface 24A of the attachment plate 24. May be. At this time, it is desirable to process or attach a film material to the portion where the elastic member comes into contact with the plate surface 24A so that the sliding resistance between the elastic member and the plate surface 24A becomes small. In addition, the number of elastic members is not limited to one and can be increased as needed.
[0038]
Further, the protective plate 11 attached to the front surface side of the sliding door 5 is not integrally formed over the whole, but as shown in FIG. 6, the flat plate 11C having a small thickness and the bent plate 11C having a larger thickness than the flat plate 11C are used. The structure which divides | segments into 2 with the board 11D may be sufficient. In this case, a flat plate 11C is formed from the left end of the sliding door 5 to a substantially central portion in the width direction, and a horizontal plate 11E, an inclined portion 11A, and a bent portion 11B are provided on a bent plate 11D disposed adjacent to the flat plate 11C. Are integrally formed.
[0039]
As described above, when the protective plate 11 is divided into the flat plate 11C and the bent plate 11, a plate having a small thickness can be used as the flat plate 11C. Therefore, the material cost of the protective plate 11 is reduced and the cost is reduced. Can be achieved.
[0040]
