The support structure 10 is a structure that supports the supported body 11 based on the installation location. The support 11 is a structure such as a vending machine, a bookshelf, or a material shelf.
For example, a pair of left and right support structures are arranged below the supported body and support the supported body.
The support structure 10 includes an intermediate member 20, a lower structure 100, an upper structure 200, an intermediate guide lower member 30, a first lower movable body 40, a second lower movable body 50, a first end guide upper member 60, and a second. The end guide upper member 70, the first upper moving body 80, and the second upper moving body 90 are configured.

  The structure of the support structure according to the second embodiment of the present invention is the structure of the support structure according to the first embodiment of the present invention except for the intermediate guide upper member 140 and the intermediate guide lower structure 30 of the lower structure 100. Because it is the same, only the differences will be explained.

The intermediate guide upper member 140 is a member that contacts the intermediate guide lower member 30 (described later) from above and guides it in the front-rear direction.
For example, when the intermediate guide lower member 30 has a roller that rotates about a rotation axis extending in the left-right direction, the intermediate guide upper member 140 has a guide surface 141 ′ (hereinafter referred to as “intermediate guide upper guide surface 141” facing downward).

In the structure shown in FIG. 13, when the upper structure 200 moves in the front-rear direction by a distance Y, the roller 31 ′ of the intermediate guide lower member 30 hits the intermediate guide upper member 140 and the upper structure 200 moves in the front-rear direction. Stop.

The intermediate guide lower member 30 is a member that is supported by the intermediate member 20 and that can contact the intermediate guide upper member 30 from above and be guided so as to be movable in a predetermined direction.
When the intermediate guide upper member 140 has a guide surface 141 ′ directed downward, the intermediate guide lower member 30 is rotatably supported by a rotating shaft 31 ′ extending along the left-right direction via a sliding bearing 32 ′. Roller 33 '.

The profile of the location where the first lower guide surface 121 contacts the first lower moving body 40 and the profile of the location where the second lower guide surface 131 contacts the second lower moving body 50 have the same size and shape. Have
The locus of the portion of the intermediate guide upper guide surface 141 ′ that contacts the intermediate guide lower member 30 may have the same size and shape as the profile.
Further, the profile may have a shape recessed downward along the front-rear direction.
Further, when the first lower moving body 40 is guided by the first lower guiding member 120 and is positioned at the lowest position, the first lower moving body 40 contacts the first lower guiding surface 121 at at least two points. May be. Alternatively, when the second lower movable body 50 is guided by the second lower guide member 131 and is positioned at the lowest position, the second lower movable body 50 may contact the second lower guide surface 131 at least at two points.
For example, when the first lower moving body 40 is a wheel, the profile is composed of a central part, a rear part, and a front part that are connected without a step, the central part has a curvature having the same dimensions as the radius of the wheel, and the rear part is It has a shape that rises as it goes backwards and rises as the front part moves forward.

The operation of the support structure according to the first or second embodiment of the present invention will be described below.
A case where a pair of left and right support structures support a supported object and an earthquake occurs will be described as an example. In addition, the first lower guide surface 121 and the second lower guide surface 131 have a concave profile, and the first upper guide surface 221 and the second upper guide surface 231 have a concave profile. Explained as an example. The case where the first lower moving body 40, the second lower moving body 50, the first upper moving body 80, and the second upper moving body 90 have wheels that rotate via a sliding bearing will be described as an example. The case where the intermediate guide upper member 140 or the intermediate guide lower member 30 has a roller supported via a sliding bearing will be described as an example.

  The first lower moving body 40 is guided by the first lower guide member 120 and is located at the lowest position. The second lower movable body 50 is guided to the second lower guide member 130 and is located at the lowest position. The first upper guide member 220 is guided by the first upper moving body 80 and is located at the lowest position. The second upper guide member 230 is guided by the second upper moving body 90 and is located at the lowest position.

When an earthquake occurs, acceleration acts on the supported body 11.
When the acceleration is small, the support structure does not move due to the frictional force acting on the sliding bearings of the first lower moving body 40, the second lower moving body 50, the first upper moving body 80, and the second upper moving body 90.
When the acceleration increases, the inertial force due to the acceleration is caused by the frictional force between the first lower moving body 40, the second lower moving body 50, the first upper moving body 80, and the second upper moving body 90 and the profile of the guide surface. Exceeds the resulting resilience. When the supported body reciprocates back and forth, left and right, the wheels of the first lower moving body 40, the second lower moving body 50, the first upper moving body 80, and the second upper moving body 90 roll, and a sliding bearing The frictional force generated in the motor absorbs acceleration energy.
When the center of gravity of the supported body is high, a rotational force that tries to overturn the supported body acts.
For example, when a large force to tilt the supported body forward acts and the contact between the second upper guide surface 231 and the second upper movable body 90 is lost, the second end guide lower member 250 and the second end The part guide upper member 70 comes into contact. The friction between the second end upper guide member 250 and the second end guide upper member 70 absorbs acceleration energy.
When the contact between the second lower guide surface 131 and the second lower moving body 50 is lost, the intermediate guide upper member 140 and the intermediate guide lower member 30 come into contact with each other. The rollers of the intermediate guide upper member 140 or the intermediate guide lower member 30 roll, and the frictional force generated in the roller slide bearing absorbs the acceleration energy.
Therefore, even when a large earthquake occurs and a large acceleration acts on the supported body, the supported body does not fall down. Further, even when acceleration that causes the supported body to fall occurs without the support structure, the support structure attenuates acceleration energy while moving the supported body in the front-rear and left-right directions.

Further, as described above, the support structure according to the present invention has the following effects depending on the configuration.
The supported member 11 is supported by the intermediate member 20, and the first lower moving body 40, the intermediate guide lower member 30, and the second lower moving body 50 are arranged in the front-rear direction and supported by the intermediate member 20, and the first lower movement The body 40 and the second lower moving body 50 are brought into contact with the guide surface installed at the installation location from below and guided in a predetermined direction, and the intermediate guide lower member 30 supported by the intermediate member 20 is installed at the installation location. Since the intermediate guide upper member 140 can be guided from above and guided in the front-rear direction, when the supported body 11 is shaken in the front-rear direction, the first lower mobile body 40 and the second lower mobile body 50 is guided in a predetermined direction by a guide surface in the lower structure, and the intermediate member 20 reciprocates in the front-rear direction. When the supported body 11 falls down in the front-rear direction, one of the first lower moving body 40 or the second lower moving body 50 floats from the guide surface in the lower structure 100, and the intermediate guide lower member 30 is moved to the intermediate guide upper member. The intermediate member 20 is reciprocated in the front-rear direction by being guided by 140 so as to be movable in the front-rear direction. Therefore, the supported body does not fall, and the acceleration acting on the supported body can be reduced.
When the first lower moving body 40 is guided to the first lower guiding member 120 and is positioned at the lowest position, the first lower moving body 40 is viewed from the orthogonal direction to the first lower guiding surface 121. The second lower moving body 50 is orthogonal to the second lower guiding surface 131 when the second lower moving body 50 is positioned at the lowest position by being guided by the second lower guiding member 130. Since the contact is made at least at two points when viewed from the direction, a certain force is required for the first lower moving body 40 to move in the predetermined direction from the lowest position, and the second lower moving body 50 is the lowest position. When a certain force is required to start moving in a predetermined direction from the first position, and the force for shaking the supported body 11 is small, the first lower moving body 40 and the second lower moving body 50 stop at the lowest position, and The support is stable.

Further, the intermediate member 20 supports the supported body 11 via the upper structure 200, the first upper moving body 80 and the second upper moving body 90 are arranged in the front-rear direction and supported by the intermediate member 20, and the first end portion The guide upper member 60 and the second end guide upper member 70 are arranged in a predetermined direction and supported by the intermediate member 20, and the first upper guide surface 221 and the second upper guide surface 231 fixed to the supported body are connected to the first upper portion. The first end guide lower member 240 and the second end guide lower member 250 fixed to the supported body 11 are brought into contact with the moving body 80 and the second upper moving body 90 from below and guided in the left-right direction. Are brought into contact with the first end guide upper member 60 and the second end guide upper member 70 from above and can be guided in the left-right direction, so that the supported body 11 is shaken in the left-right direction. , First upper moving body 80 and second upper moving body 90 and guides the upper structure 200 in the lateral direction, the upper structure 200 is reciprocated in the lateral direction. When the supported body 11 falls over in the front-rear direction, one of the first upper moving body 80 or the second upper moving body 90 moves away from the guide surface in the upper structure 200 and the first end guide lower member 240 or the second The end guide lower member 250 is guided by the first end guide upper member 60 or the second end guide upper member 70 so as to be movable in the left-right direction, and the supported body reciprocates in the front-rear and left-right directions. Therefore, the supported body 11 does not fall, and the acceleration acting on the supported body 11 can be reduced.
Also, a guide surface is provided on the first end guide lower member 240 or the second end guide lower member 250, and the guide surface extends in the left-right direction on the first end guide upper member 60 or the second end guide upper member 70. The guide trajectory of the first upper guide surface 221 and the guide trajectory of the first end guide lower guide surface 241 have the same size and shape, and the second upper guide surface 231 is guided. Since the trajectory for use and the guide trajectory for the second end guide lower guide surface 251 have the same size and shape, the first upper guide surface 221 is The second upper guide surface 231 is guided in the left-right direction by the first upper moving body 80, and the first end guide upper member 60 and the first end guide lower member 240 or Second end guide upper member 70 and first The vertical gap dimension of the end guide the lower member 250 can be held at zero or substantially constant value.

In the support structure according to the first embodiment, the intermediate guide lower member 30 is provided with a guide surface 31 facing upward, and the guide surface 31 is guided in the front-rear direction by the intermediate guide upper member 140. The guide trajectory of the first lower guide surface 121 and the guide trajectory of the second lower guide surface 131 have the same profile, and the guide trajectory of the intermediate guide lower member 30 is a line object in the vertical direction with the profile. Therefore, when the intermediate member 20 reciprocates in the front-rear direction, the first lower moving body 40 is brought into contact with the first lower guide surface 121 and guided in a predetermined direction, and the second lower moving body 50 is moved to the second lower portion. The guide surface 131 is brought into contact with the guide surface 131 and guided in a predetermined direction, so that the vertical gap between the intermediate guide upper member 140 and the intermediate guide lower member 30 can be maintained at zero or a substantially constant value.
Further, the wheels of the first lower moving body 40 and the second lower moving body 50 roll while being guided by the guide surface via the sliding bearing 52, and the roller of the intermediate guide upper member 140 passes through the sliding bearing. Therefore, when the supported body 11 is shaken horizontally, the first lower moving body 40 and the second lower moving body 50 are brought into contact with each other. Moving on the guide surface of the lower structure 100, the acceleration acting on the supported body 11 is attenuated by the friction of the sliding bearing. When the supported body 11 falls over, the intermediate guide upper member 140 rolls on the guide surface of the intermediate guide lower member 30, and the acceleration acting on the supported body is attenuated by the friction of the sliding bearing. Therefore, acceleration acting on the supported body can be reduced.

In the support structure according to the second embodiment, the intermediate guide upper member 140 is provided with a guide surface 141 ′ directed downward, and the guide surface 141 ′ guides the intermediate guide lower member 30 in the front-rear direction. The guide locus of the first lower guide surface 121 and the guide locus of the second lower guide surface 131 have the same profile, and the guide locus of the intermediate guide upper member 140 is the same as that profile. When the intermediate member 20 reciprocates in the front-rear direction, the first lower moving body 40 is brought into contact with the first lower guiding surface 121 and guided in a predetermined direction, and the second lower moving body 50 is moved to the second lower guiding surface 131. The vertical gap between the intermediate guide upper member 140 and the intermediate guide lower member 30 can be maintained at zero or a substantially constant value.
Further, the wheels of the first lower moving body 40 and the second lower moving body 50 are guided by the guide surface through the sliding bearing 52 and roll, and the roller of the intermediate guide lower member 30 is moved through the sliding bearing. Since the rolling is guided by the guide surface provided on the intermediate guide upper member 140, the first lower moving body 40 and the second lower moving body 50 are moved to the lower side when the supported body 11 is shaken horizontally. Moving on the guide surface of the structure 100, the acceleration acting on the supported body 11 is attenuated by the friction of the sliding bearing. When the supported body 11 falls, the intermediate guide lower member 30 rolls on the guide surface of the intermediate guide upper member 140, and the acceleration acting on the supported body is attenuated by the friction of the sliding bearing. Therefore, acceleration acting on the supported body can be reduced.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.
