Description

  The present invention relates to a fixture for a device with a caster, and in particular, when an earthquake occurs, an OA device, a medical device, a precision machine, a fireproof safe, a refrigerator, a temporary heavy object, and other caster-equipped devices run away or fall over. In order to prevent this, the present invention relates to a fixture that fixes the caster-equipped device to the floor surface.

  In order to prevent the furniture from falling over when an earthquake occurs, a fixture that fixes the furniture to the wall surface (hereinafter referred to as “conventional fixture”) is disclosed in Japanese Patent Laid-Open No. 11-75975. .

A conventional fixture is formed by fixing a mounting piece to the upper surface or side surface of furniture by screwing, fixing a fixing portion to a wall surface by screwing, and connecting the mounting piece and the fixing portion by a spring.
JP-A-11-75975

  However, the above-described conventional fixing tool is difficult to use as a fixing means for a device with casters for the following reason.

(B) Many caster-equipped devices are made of metal, but it is difficult to screw and fix the mounting piece on the upper surface or side surface of the caster with metal casters.

(B) Since the device with casters is not necessarily used in the state of being close to the wall surface, it is not appropriate to fix the device with casters to the wall surface.

(C) Since the equipment with casters is provided with casters, even if the equipment with casters is fixed to the wall surface by the fixing tool, the equipment with casters may fall down when an earthquake occurs.

  A caster-equipped device may run away on the floor in the event of an earthquake, or may fall over after running away. In particular, when an earthquake occurs during use of a medical device, an extremely dangerous state is caused in which the medical device runs away and falls. This danger cannot be avoided by simply locking the caster so that it cannot rotate.

  In view of such a situation, the present invention is intended to provide a fixture for a caster-equipped device in which the caster-equipped device is releasably secured to a floor surface.

  In order to solve the above-described problems, the present invention provides the following fixture for a device with casters.

(1) Male threaded rods having lead angles opposite to each other are provided on the opposing surfaces of the pair of flat plates, and the other surface is provided with adhesive means for the bottom surface and floor surface of the caster-equipped device, On the other hand, each end of the cylindrical body is provided with a female screw corresponding to the male thread of each male threaded rod, and each male threaded rod is screwed to each end of the cylindrical body, thereby rotating the cylindrical body. Make sure that each plate moves in the direction of contact with each other,
The pair of flat plates are fixed to the bottom surface and the floor surface of the caster-equipped device by adhesive means by rotating the cylindrical body with the fixture placed at an appropriate position on the floor surface below the caster-equipped device. A fixing device for a caster-equipped device, wherein the caster-equipped device is fixed to the floor in a state in which the load of the caster-equipped device is not applied to the caster (Claim 1).

(2) A nut having a female screw corresponding to the male screw of each male screw rod is attached to each end of the cylindrical body in order to provide each end of the cylindrical member with a female screw corresponding to the male screw of each male screw rod. Item 2).

[Invention of Claim 1]
When a plurality of fixtures are attached at predetermined positions and the caster-equipped device is fixed to the floor in a state where the load of the caster-equipped device is not applied to the caster, the caster loses its function. Therefore, when an earthquake occurs, there is no possibility that the caster-equipped device runs out of control on the floor or falls down after running out of control.

  By simply rotating the tubular body with the fixture placed at an appropriate position on the floor below the equipment with casters, the equipment with casters can be fixed on the floor very easily.

  By rotating the cylindrical body, the flat plates move in a direction that makes contact with and away from each other, so that the fixture can be used without any problems even if the height of the bottom surface of the equipment with casters is different from the floor surface. .

  If it is necessary to run the caster-equipped device again on the caster after attaching the fixture, the plates are moved in the direction approaching each other by rotating the cylindrical body in a predetermined direction. Can be removed.

  In the case of a device with casters that must maintain a horizontal state, the casters are adjusted by adjusting the distance between a pair of flat plates in a plurality of fixtures attached at predetermined positions by rotating the cylindrical body. The horizontal state of the attached device can be secured.

[Invention of claim 2]
In order to equip each end of the cylindrical body with a female screw corresponding to the male screw of each male threaded rod, a nut having a female thread corresponding to the male thread of each male threaded rod is attached to each end of the cylindrical body. The manufacturing cost of the body is reduced.

  Reference numeral 1 indicates a fixture, reference numeral 3 indicates a floor surface, reference numeral 5 indicates a device with casters, and reference numeral 7 indicates a caster attached to the bottom surface 9 of the caster-equipped device 5.

  What is indicated by reference numerals 11a and 11b is a pair of opposing flat plates. Male threaded rods 15a and 15b having lead angles opposite to each other are provided on the opposing surfaces 13a and 13b of the flat plates 11a and 11b, respectively. For example, a right male screw 16a is formed on one male screw rod 15a, and a left male screw 16b is formed on the other male screw rod 15b.

  The other surfaces 17a and 17b of the flat plates 11a and 11b are provided with adhesive means 19a and 19b for the bottom surface 9 and the floor surface 3 of the apparatus 5 with casters, respectively.

  As the adhesive means 19a and 19b, for example, a plate-like body made of gel-like ultrasoft urethane having adhesiveness is used.

  What is shown by the code | symbol 21 is a cylindrical body. Each end of the cylindrical body 21 is provided with female threads 23a, 23b corresponding to the male threads 16a, 16b of the male threaded rods 15a, 15b, and each male threaded rod 15a, 15b is provided with an internal thread 23a, at each end of the cylindrical body 21, 23b.

  That is, by rotating the cylindrical body 21 with respect to the male threaded rods 15a and 15b, the respective flat plates 11a and 11b are moved in a direction in which they contact and separate from each other. Incidentally, the direction in which they contact and separate from each other refers to the direction in which the interval between the flat plates 11a and 11b is changed.

  By rotating the cylindrical body 21 in a state where the fixture 1 is placed at an appropriate position on the floor surface 3 below the caster-equipped device 5, the pair of flat plates 11a and 11b are respectively connected to the bottom surface 9 of the caster-equipped device 5. The caster-equipped device 5 is fixed to the floor 3 while being fixed to the floor surface 3 by adhesive means 19a, 19b so that the load of the caster-equipped device 5 is not applied to the caster 7.

Female screws 23a and 23b corresponding to the male screws 16a and 16b of the male screw rods 15a and 15b may be directly formed at each end of the cylindrical body 21 (see FIG. 4), but at each end of the cylindrical body 21 You may attach nut 25a, 25b which has the internal thread 23a, 23b corresponding to the external thread 16a, 16b of each external thread rod 15a, 16b.

It is a front view which shows an example of the use condition of the fixing tool by this invention. It is a perspective view which shows a fixing tool same as the above. It is sectional drawing which shows a fixing tool same as the above. It is sectional drawing which shows another example of a fixing tool.
