Description

  The present invention relates to a base structure that is installed in a lower part of an apparatus and includes moving means such as casters.

  Conventionally, the base located at the lower part of the apparatus has a function of moving the entire apparatus relative to the floor surface as well as a function of originally holding the apparatus in an upright state. Therefore, the base is provided with moving means such as a plurality of casters and rollers. Hereinafter, the moving means will be described as a caster.

  The base is composed of an upper surface portion and a side surface portion, and has an inverted container shape with an opening at the bottom. However, the caster is not completely hidden by the base but protrudes downward by a predetermined dimension (for example, 3 cm) from the lower end of the base. Therefore, a gap corresponding to the predetermined dimension is opened between the lower end of the base and the floor surface.

  This gap corresponds to the protrusions and slopes on the floor, so that the bottom end of the base does not interfere with the slight protrusions or inclinations on the floor when moving the base. (For example, refer to Patent Document 1).

US Pat. No. 6,105,909

  However, in such a conventional technique, since there is a gap between the lower end of the base and the floor surface, interference between the lower end of the base and the protrusions on the floor surface during the movement of the base can be avoided. However, there is a possibility that the wiring existing on the floor (the wiring of the device itself or the wiring of the peripheral device) enters the base from the gap, and the caster steps on the wiring. When the wiring is stepped on by a caster, the wiring is damaged. Therefore, when moving the base, it is necessary to always move the base while removing the wiring with hands and feet, and the moving operation is troublesome.

  The present invention has been made paying attention to such a conventional technique, and provides a base structure of an apparatus capable of moving while automatically removing wiring on a floor surface.

The invention according to claim 1 is composed of an upper surface portion and a side surface portion, and has a tip portion protruding in all directions in a plan view, and an inverted container-shaped base having an open bottom is installed at the lower portion of the apparatus, and A plurality of moving means for moving on the floor surface in a state of projecting downward by a predetermined dimension from the lower end of the base is provided inside each tip end portion of the base, and between the lower end of the base and the floor surface, In the base structure of the apparatus in which a gap corresponding to the dimension is formed, the length or floor reaching the floor surface only at a position close to each moving means surrounding each moving means on the side surface portion of each tip of the base A wiring removing body formed of a material that has a length almost reaching the surface and is elastically deformable is attached by fixing an upper portion thereof.

  In the invention according to claim 2, the wiring removal body is made of rubber.

  The invention described in claim 3 is characterized in that the wiring removal body is in the shape of a strip plate, and a plurality of wiring removal bodies are attached along the side surface portion of the base so as to surround each moving means.

  The invention described in claim 4 is characterized in that the wiring removal body is in the shape of a round bar, and a plurality of wiring removal bodies are attached along the side surface of the base so as to surround each moving means.

  The invention according to claim 5 is characterized in that the wiring removal body is a wide plate shape and is attached in a curved state along the side surface of the base so that one wiring removal body surrounds each moving means. And

  According to the sixth aspect of the present invention, a concave portion having a shape corresponding to the upper portion of the wiring removing body is formed on the lower end surface of the side surface portion of the base, and the upper portion of the wiring removing body is inserted into the concave portion. It is characterized by that.

  According to the first aspect of the present invention, since the wiring removing body is attached at a position close to each moving means on the side surface of the base, when the base is moved to the position of the wiring on the floor surface when the base is moved, The removal body comes into contact with the wiring, the wiring removal body pushes the wiring as it is, and the wiring moves together with the base. Therefore, the wiring does not enter the inside of the base through the gap and is not stepped on by the caster. In addition, when moving the base, even if the wiring removal body hits a protrusion on the floor surface, the wiring removal body is elastically deformed when the other party is a fixed object. The original function due to the formation is maintained.

  According to the invention described in claim 2, since the wiring removal body is made of rubber, it is easy to mold and inexpensive.

  According to the third aspect of the present invention, since the plurality of strip-shaped wire removal bodies are attached along the side surface of the base so as to surround the moving means, in which direction the base is moved. In both cases, the wiring coming in the direction of being stepped on the caster can be reliably brought into contact with the wiring removing body.

  According to the fourth aspect of the present invention, since the wiring removal body has a round bar shape, it can be easily molded and can be easily attached to the side surface of the base.

  According to the fifth aspect of the present invention, since one wiring removing body having a wide plate shape is attached so as to surround each moving means, the wiring removing body is attached to each moving means. It only needs to be done once, and it is easy to install the wiring removal body. Moreover, since one wiring removal body curves along the side surface portion of the base, the rigidity of the wiring removal body is increased, and the force of pushing the wiring by the wiring removal body is improved.

  According to the sixth aspect of the present invention, since the wiring removal body is attached in a state of being inserted into the recess formed in the lower end surface of the side surface portion of the base, the wiring removal body protrudes in a skirt shape from the lower end of the base. A sense of unity with the base comes out and the appearance improves.

  Hereinafter, preferred embodiments of the present invention will be described. 1-5 is a figure which shows 1st Embodiment of this invention. FIG. 1 shows a medical stand device 2 that supports a surgical microscope 1. A base 3 is provided below the stand device 2. The stand device 2 is standing on the floor surface 4 by the base 3. On the floor surface 4 around the base 3, peripheral device wiring 5 exists. In addition, wiring 6 from the stand device 2 itself also exists around the base 3.

  The base 3 has a substantially cross shape protruding in four directions in a plan view, and has a reverse container shape opened downward. Specifically, it is an aluminum alloy casting composed of an upper surface portion 7 and a side surface portion 8 extending downward from the peripheral edge thereof, and has a certain weight as a whole. The main body of the stand device 2 is fixed to the central portion of the base 3.

  A caster 9 as a “moving means” is attached to the back surface of the upper surface portion 7 at each front end portion protruding in the four directions of the base 3. The caster 9 is formed of a roller portion 10 and a holding portion 11 that holds the roller portion 10 rotatably.

  The roller portion 10 projects downward by a predetermined dimension (about 3 mm) from the lower end of the side surface portion 8 of the base 3. Accordingly, a gap S having a vertical dimension corresponding to the predetermined dimension is formed between the lower end of the side surface portion 8 and the floor surface 4.

  Therefore, when the base 3 is moved on the floor surface 4, even if there are some protrusions 14 and inclinations on the floor surface 4, if the vertical dimension is smaller than the gap S, strong interference with them is avoided. Can do.

  And the wiring removal body 12 is attached to the front-end | tip part of the base 3 to which the caster 9 was each attached downward from the lower end surface of the side part 8. As shown in FIG. The wiring removal bodies 12 are in the shape of strips, and are attached to the casters 9 at intervals so as to surround the casters 9 at positions close to the casters 9.

  The wiring removal body 12 is made of elastic rubber having a certain degree of hardness and always maintains a certain shape, but is bent by elastic deformation when a strong force is applied. Since the wiring removal body 12 is made of rubber, it is easy to mold and inexpensive.

  A concave portion 13 having a shape corresponding to the upper portion of the wiring removal body 12 is formed in advance on the lower end surface of the side surface portion 8. The upper part of the wiring removal body 12 is inserted into the recess 13 via an adhesive. The upper part of the wiring removal body 12 is fixed in the recess 13 by an adhesive and protrudes downward from the lower end of the side surface part 8. The wiring removing body 12 protrudes in a skirt shape from the lower end of the base 3, and a sense of unity with the base 3 comes out and the appearance is good.

  The wiring removal body 12 protruding downward from the lower end of the side surface portion 8 has a length where the lower end is just in contact with the floor surface 4.

  Next, the operation will be described. For example, when the stand device 2 is to be moved in the direction of arrow A in FIG. 1, the wiring 5 exists on the floor surface 4 in that direction. It was necessary to keep it.

  However, in this embodiment, since the wiring removal body 12 is attached to the lower end of the base 3, it is safe to forget to eliminate the wiring 5. That is, even if the base 3 is moved in the direction A in which the wiring 5 exists, when the base 3 comes to the position of the wiring 5 on the floor surface 4, as shown in FIG. In contact with each other, the wiring removal body 12 pushes the wiring 5 as it is, so that the wiring 5 moves together with the base 3. Accordingly, the wiring 5 does not enter the base 3 through the gap S and is not stepped on by the casters 9.

  In particular, since the wiring removal body 12 is attached so as to surround the caster 9, the wiring 5 coming in the direction to be stepped on the caster 9 is surely attached to the wiring removal body 12 regardless of the direction in which the base 3 is moved. You can guess.

  The caster 9 may step on the wiring 6 of the stand device 2 itself as well as the wiring 5 of the peripheral device. However, the caster 9 is also the same in the case of the own wiring 6. There is no risk of being stepped on.

  Further, when the base 3 is moved, if the wiring removing body 12 hits the protrusion 14 of the floor surface 4 instead of the wiring 5, the opponent is a fixed object and the reaction force is large. As shown, the wiring removal body 12 is elastically deformed and passes through the gap S. In this way, strong interference between the base 3 and the protrusions 14 is avoided, and the original function due to the formation of the gap S is maintained as it is.

  6 and 7 are views showing a second embodiment of the present invention. Note that, in the following embodiments, the same reference numerals are given to portions common to the previous embodiments, and redundant description will be omitted.

  In this embodiment, the base 15 has a substantially rectangular shape and is formed of an upper surface portion 16 and a side surface portion 17. The four corner portions 15a of the base 15 are curved in a chamfered state, and casters 9 are attached to the back surface of the upper surface portion 17 corresponding to the corner portions 15a.

  A round bar-shaped wiring removal body 18 is attached to the lower end surface of the side surface portion 17 in the corner portion 15a. The wiring removal body 18 is made of elastic vinyl having a certain degree of hardness. The wiring removal body 18 has a length where the lower end is just in contact with the floor surface. The wiring removal body 18 is attached in the same manner as in the previous embodiment. However, since the shape is a round bar, the attachment work is easier than in the previous embodiment. In addition, it is easy to mold due to the round bar shape.

  Also in this embodiment, no matter which direction the base 15 is moved, the wiring can be applied to the wiring removal body 18 and the wiring can be pushed together with the wiring removal body 18 and moved together.

  8 and 9 are diagrams showing a third embodiment of the present invention. In this embodiment, the base 19 is circular and is formed of an upper surface portion 20 and a side surface portion 21. Casters 9 are respectively attached to the back surface of the upper surface portion 20 at four orthogonal positions of the base 19.

  A wide plate-shaped wiring removal body 22 is attached to each of the side surfaces 21 of the base 19 one by one with respect to the casters 9 at positions corresponding to the casters 9. The wiring removal body 22 is made of a rubber plate, and surrounds the caster 9 while being curved along the side surface portion 21. The wiring removal body 22 has a length that the lower end just touches the floor surface.

  The wiring removal body 22 is attached in the same manner as in the previous embodiment. However, since one sheet is attached to each caster 9, the wiring removal body 22 is attached to each caster 9 only once. The wiring remover can be easily attached.

  In addition, since one wiring removal body 22 is curved along the side surface portion 21 of the base 19, the rigidity of the wiring removal body 22 is increased, and the force of pushing the wiring by the wiring removal body 22 is improved. Therefore, the wiring can be reliably pushed by the wiring removal body 22 and moved together. However, since the wiring removal body 22 remains elastically deformable, when the wiring removal body 22 hits a protrusion on the floor surface, the wiring removal body 22 is elastically deformed to allow passage of the protrusion or the like.

  In the above embodiment, the length of the wiring removing bodies 12, 18, and 22 is set to be just in contact with the floor surface 4, but may be a little longer than that and can be pushed by the wirings 5 and 6. If there is, it may be slightly shorter.

  As a modification, the wiring removal bodies 12, 18, and 22 may have a shape that extends toward the outside of the base 3 as it approaches the floor surface 4. When such a wiring removal body abuts against the wiring 5 when the base 3 is moved, a force for further scooping is applied to the wiring 5. Therefore, friction between the wiring 5 and the floor surface 4 is reduced, and the movement of the wiring 5 is facilitated.

  In addition, as an elastically deformable material for forming the wiring removal bodies 12, 18, and 22, rubber and vinyl are taken as an example, but a metal plate, a resin plate, a coil spring, and the like may be used. Further, the moving means is not limited to a caster.
