Description

  The present invention relates to an adjuster device used when a storage for storing articles such as foods is installed at an installation site.

  2. Description of the Related Art Conventionally, a low temperature storage as a storage for storing articles such as foods while being cooled is composed of a heat insulating box (box), and a storage chamber is formed in the heat insulating box. The storage room is cooled to a predetermined refrigeration or freezing temperature with a cooling device, but the floor surface of the installation site is usually not completely flat, or it is stable by floating from the moving wheel. Therefore, an adjuster device comprising an adjuster bolt for height adjustment is used.

  The adjuster bolts of the adjuster device are provided in through holes formed in the bottom wall of the heat insulation box corresponding to the four corners of the floor of the storage chamber, and project downward from the heat insulation box. And conventionally, the amount of protrusion was adjusted from the heat insulation box by rotating this adjuster bolt from the storage chamber side, and the unevenness of the floor surface of the installation site was absorbed.

Further, since the adjuster bolt can be rotated from the inside of the storage chamber in this way, for example, when the back surface and the left and right surfaces of the cryogenic chamber are installed close to the wall surface of the installation site, the adjuster on the back side is particularly suitable. The bolt can be easily rotated (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 11-82880

  However, in such a conventional adjuster device, since there is a relatively large through-hole for rotating the adjuster bolt in the bottom wall of the heat insulation box, foreign matter falls from the storage chamber side, or the appearance There is a problem that gets worse. For this reason, it is necessary to attach a cap or the like to the through hole storage chamber side after the height adjustment is completed. Further, since the through hole communicates with the inside and outside of the storage chamber, a problem of airtightness arises if this cap is forgotten. In addition, there is a risk that the cap may come off when the article is delivered into the storage chamber, and if the cap is moved many times, the airtightness of the cap will deteriorate.

  Furthermore, in the case of a low-temperature warehouse that cools the storage chamber, heat insulation is also deteriorated due to the presence of a through-hole that communicates with the outside of the storage chamber. It is necessary to cover with a heat insulating cover from the storage chamber side or with a heat insulating material from the outside of the warehouse. However, when filling with heat insulating material or covering with heat insulating material from the outside of the warehouse, when re-installing or moving, it is necessary to remove the heat insulating material to redo height adjustment, and the work becomes troublesome and storage In the case where the heat insulating cover is attached from the room side, there is a disadvantage in that it protrudes greatly on the floor surface and becomes an obstacle. Furthermore, when filling with a heat insulating material or attaching a heat insulating material to the outside of the warehouse, there is a problem that these heat insulating materials are damaged when the adjuster bolt is turned from the outside (below the bottom wall).

  The present invention has been made to solve the conventional technical problem, and provides an adjuster device that does not make a through-hole communicating with the outside of the storage chamber in the bottom wall of the box of the storage.

  The adjuster device of the present invention is configured such that a storage chamber is formed in the box body, and is rotated into the bottom wall of the box body that constitutes the floor surface of the storage chamber in a storage room provided with an adjuster bolt protruding downward from the box body. A swivel member provided freely, and engaging the swivel member with an adjuster bolt, exposing the upper surface of the swivel member to the floor surface of the storage chamber, and rotating the swivel member from the storage chamber, The adjuster bolt is rotatable.

  The adjuster device of the storage of the invention of claim 2 is characterized in that, in the above, the box is a heat insulating box, the storage chamber is cooled to a predetermined temperature, and the swivel member is made of a heat insulating material. And

  According to a third aspect of the present invention, there is provided the adjuster device for a storage, in which the upper surface of the swivel member is substantially flush with the floor surface of the storage chamber, and the upper surface is an engaging portion for engaging a tool. Is characterized in that it is recessed.

  According to a fourth aspect of the present invention, there is provided a storage adjuster device according to the first or second aspect, wherein a handle portion located in the storage chamber is integrally formed on the upper surface of the turning member.

  According to the adjuster device of the present invention, a storage chamber is configured in the box body, and in a storehouse provided with an adjuster bolt projecting downward from the box body, in the bottom wall of the box body constituting the floor surface of the storage chamber. A swivel member provided rotatably is engaged, and the swivel member is engaged with an adjuster bolt, and the upper surface of the swivel member is exposed to the floor surface of the storage chamber, and the swivel member is rotated from the storage chamber. Thus, the adjuster bolt can be turned. Therefore, the adjuster bolt can be turned simply by turning the turning member from the storage chamber side, and the height of the storage can be adjusted very easily.

  In this case, there is no through-hole communicating between the inside and outside of the storage chamber in the bottom wall of the box, so that airtightness is good and there is no need to close it with a cap or the like as in the prior art, and re-installation and relocation work is troublesome. And inconveniences such as the cap being removed and airtightness being deteriorated do not occur. Further, even if it is used repeatedly, there is no problem of performance degradation. In particular, swiveling members, adjuster bolts, etc. can be attached at the time of assembling the storage, so there is no need to attach parts at the installation site as in the past, and there is no need to attach / remove caps etc. when moving. The airtightness can be reliably maintained.

  Further, when the box is a heat insulating box as in the invention of claim 2 and the storage chamber is cooled to a predetermined temperature, the revolving member is made of a heat insulating material, so that the heat insulating material can be specially insulated. Without attaching a cover or the like, the adjuster device can prevent inconveniences that adversely affect the cooling performance in the storage chamber to ensure heat insulation, and the parts are not damaged when the adjuster bolt is rotated from the outside. Moreover, since a special heat insulating material becomes unnecessary, this also improves the relocation work.

  Furthermore, if the upper surface of the swivel member is substantially flush with the floor surface of the storage chamber as in the third aspect of the invention, and the engaging portion for engaging the tool is formed in the upper surface, the access to the storage chamber is achieved. The swiveling member hardly protrudes into the storage chamber when the article is delivered, and does not get in the way. In this case, the tool can be engaged with the engaging portion to rotate the swivel member, so that the height can be adjusted without any trouble.

  Conversely, if the handle portion located in the storage chamber is integrally formed on the upper surface of the swivel member as in the invention of claim 4, the swivel member can be rotated by holding this handle portion without using a special tool. You will be able to adjust the height.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  Further, as described above, the turning member 13 is rotatably inserted into the sleeve 26 embedded in the bottom wall 2A. The swivel member 13 is also made of a hard synthetic resin (such as a Teflon (registered trademark) material having a smooth surface) having a low thermal conductivity and a heat insulation property, and has a cylindrical shape. A circular protrusion 27 having a height substantially equal to the thickness of the inner surface material 21 is formed on the upper surface of the swivel member 13, and the protrusion 27 has a dimension capable of entering the window hole 22 of the inner surface material 21. is doing. In addition, a cross-shaped engagement portion 28 is formed in the projection 27 so as to be recessed.

  An insertion portion 29 that opens at the lower surface is formed in the turning member 13. The insertion portion 29 has a shape and dimensions that allow the adjuster bolt 8 shown in FIG. 5 to enter, and is formed up and down to the lower side of the protrusion 27 on the upper surface. It matches the axis. Further, vertical grooves 29A, 29A are formed vertically at positions symmetrical with respect to the axis, and the lower ends of the vertical grooves 29A, 29A are also opened at the lower surface of the turning member 13. Further, the outer diameter dimension of the swivel member 13 is set to a dimension in which a small clearance can be inserted into the sleeve 26 so as to be freely rotatable.

  On the other hand, a circular through-hole 16B into which the turning member 13 can enter is formed in the upper wall 16A of the angle 16 positioned vertically below the sleeve 26. The upper part of the swivel member 13 is rotatably inserted into the sleeve 26, and the lower part is rotatably inserted into the through hole 16B of the angle 16. At this time, the protrusion 27 on the upper surface of the turning member 13 enters the window hole 22 of the inner surface material 21 and is exposed to the floor surface of the storage chamber 3 so that the upper surface is substantially flush with the upper surface of the inner surface material 21.
