Description

  The present invention relates to a housing support apparatus.

  There is a technique in which a caster is attached to the bottom surface of a housing such as a device or furniture (hereinafter referred to as “device housing”) to improve convenience when the device or the like is moved. In many cases, a member called an adjuster is provided. The adjuster is a member that secures a necessary distance between the bottom surface and the floor of the housing by a bolt fixed to the housing and a rotating member in which an internal thread is cut (see, for example, Patent Document 1). . Generally, an anti-slip member such as rubber is disposed on the grounding surface of the adjuster.

JP 2001-204567 A

  However, when installing equipment on a soft floor, if rubber or the like is used for the grounding surface of the adjuster, the rubber will move on the soft floor surface, so that it cannot be fixed sufficiently, and the stability of the equipment will be impaired. There is a risk that. For soft floors, it is effective to fix the protrusions deeply. However, the method of biting and fixing the protrusions is not suitable for a hard floor. That is, the protrusion slides on the floor, and the device cannot be fixed.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a housing that can stably install a device or the like regardless of whether the floor on which the device or the like is installed is a hard floor or a soft floor. The object is to provide a body support device.

  An image forming apparatus according to the present invention is a housing support device that supports an apparatus housing, and includes a first support and a second support provided around the first support. The first support moves between a position in a first state protruding from the bottom surface of the two supports and a position in a second state not protruding from the bottom surface of the second support. The second support moves in conjunction with the movement of the first support and moves a distance shorter than the distance of the movement of the first support.

  According to the housing support apparatus of the present invention, the apparatus or the like can be stably installed regardless of whether the floor on which the apparatus or the like is installed is a hard floor or a soft floor.

  Hereinafter, with reference to the drawings, embodiments of a housing support device according to the present invention will be described. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof is not repeated.

  First, with reference to FIG. 1, the outline | summary of the housing | casing support apparatus which concerns on this invention is demonstrated. FIG. 1 is a perspective view showing an external appearance of an image forming apparatus 1 to which a housing support device according to the present invention is applied. In the present embodiment, the image forming apparatus 1 is, for example, a digital multifunction machine having a copying function, a printing function, a facsimile function, and the like. Further, the weight of the image forming apparatus 1 is about 100 kg.

  The image forming apparatus 1 includes an apparatus body 2 and housing support apparatuses 10a to 10d. As shown in FIG. 1, the case supporting devices 10 a to 10 d are disposed between the four corners of the bottom of the device main body 2 and the floor. Each of the housing support devices 10 a to 10 d supports stable installation of the apparatus main body 2 by adjusting the height from the floor to the bottom of the image forming apparatus 1. The housing support device 10 is a general term for the housing support devices 10a to 10d.

  Here, the floor on which the image forming apparatus 1 is installed is roughly classified into two types. The first floor is a soft floor such as carpet. When the housing support device 10 has a protruding member at a portion in contact with the floor, the protruding member bites into a carpet or the like, so that the image forming apparatus 1 can be fixed. On the other hand, it is necessary to prevent the carpet or the like from being damaged by the protruding member of the housing support device 10.

  The second floor on which the image forming apparatus 1 is installed is a hard floor such as concrete. In the case of a hard floor, even if the housing support device 10 has a protruding member, it slides on the floor. For this reason, it is difficult to fix the image forming apparatus 1 on a hard floor only by having the projecting member in the housing support device 10.

  Next, with reference to FIG. 2, the structure of the housing support apparatus 10 according to the present invention will be described. FIG. 2A is a perspective view showing the appearance of the housing support apparatus 10. FIG. 2B is a cross-sectional view of the housing support apparatus 10 shown in FIG.

  The housing support device 10 includes a first support 11, a second support 12, a fixed plate 13, and an adjuster plate 14. The first support 11 includes a shaft bolt 111, a base member 112, and a protruding member 113.

  The shaft bolt 111 is a cylindrical bolt and is the central axis of the first support 11. A base member 112 is connected to the lower side of the shaft bolt 111. The shaft bolt 111 rotates in conjunction with the rotation of the rotation member 123 of the second support 12. Further, the shaft bolt 111 has a first male screw having a first pitch engraved on a part of the outer peripheral surface thereof, and is screwed with a first female screw engraved on the fixing plate 13. Therefore, when the user rotates the rotation member 123 of the second support 12 in the right direction (that is, the direction of the right screw), the shaft bolt 111 also rotates in the right direction in conjunction with the rotation member 123. When the shaft bolt 111 rotates in the right direction, the first support 11 moves upward. Conversely, when the user rotates the rotating member 123 of the second support 12 in the left direction, the shaft bolt 111 rotates in the left direction in conjunction with the rotating member 123. When the shaft bolt 111 rotates in the left direction, the first support 11 moves downward. The shaft bolt 111 is an example of a first bolt.

  The base member 112 is a member connected to the lower side of the shaft bolt 111. A plurality of projecting members 113 are disposed below the base member 112.

  The protruding member 113 is a convex member made of a material capable of biting a soft floor such as a carpet. A plurality of protruding members 113 are disposed on the base member 112. The protruding member 113 is, for example, a convex member having a hard plastic material and an inverted triangular pyramid shape.

  The second support 12 is a support provided around the first support 11, and includes a hollow bolt 121, a torque limiter 122, and a rotating member 123.

  The hollow bolt 121 is a cylindrical bolt and is a central member of the second support 12. A torque limiter 122 is connected to the upper part of the hollow bolt 121. The hollow bolt 121 rotates in conjunction with the rotation of the rotation member 123. Further, the hollow bolt 121 has a second male screw with a second pitch engraved on a part of the outer peripheral surface thereof, and is screwed with a second female screw engraved on the adjuster plate 14. Therefore, when the rotation member 123 is rotated in the right direction (that is, the direction of the right screw) by the user, the hollow bolt 121 is also rotated in the right direction in conjunction with the rotation member 123. When the hollow bolt 121 rotates in the right direction, the second support 12 moves upward. Conversely, when the user rotates the rotation member 123 in the left direction, the hollow bolt 121 rotates in the left direction in conjunction with the rotation member 123. When the hollow bolt 121 rotates in the left direction, the second support 12 moves downward.

  Further, the second pitch of the second male screw of the hollow bolt 121 is smaller than the first pitch of the first male screw of the shaft bolt 111. For example, the second pitch of the second male screw of the hollow bolt 121 is “1/3” of the first pitch of the shaft bolt 111. Accordingly, when the shaft bolt 111 moves 3 [cm] by the rotation of the rotating member 123, the hollow bolt 121 moves 1 [cm]. The hollow bolt 121 is an example of a second bolt.

  The torque limiter 122 releases the connection with the shaft bolt 111 which is an inner member when the torque applied by the user's turning operation via the turning member 123 exceeds a predetermined torque. Thus, when torque is applied to the rotating member 123 in a state where the connection with the shaft bolt 111 is released, the rotation of the shaft bolt 111 stops and only the hollow bolt 121 rotates.

  The rotating member 123 is a member having a thick and hollow cylindrical shape. The rotating member 123 transmits torque accompanying the rotation operation by the user to the first support body 11 and the second support body 12. In the second support 12, when the torque limiter 122 is activated, the torque accompanying the turning operation by the user is not transmitted to the first support 11, but is transmitted only to the second support 12. The rotating member 123 can be formed of a material having a large friction coefficient. The material of the rotating member 123 is rubber, for example.

  The fixing plate 13 is a member for fixing the casing support device 10 to the image forming apparatus 1. A first female screw is engraved on the fixing plate 13 and is screwed with a first male screw engraved on the shaft bolt 111. The material of the fixed plate 13 is stainless steel, for example. The fixing plate 13 is an example of a first fixing member.

  The adjuster plate 14 fixes the second support 12 to the fixed plate 13. A second female screw is engraved on the fixing plate 13 and is screwed with a second male screw engraved on the hollow bolt 121. The material of the adjuster plate 14 is, for example, stainless steel. The adjuster plate 14 is an example of a second fixing member.

  Next, the housing support apparatus 10 according to the present embodiment will be specifically described with reference to FIGS. 3 to 8. First, with reference to FIGS. 3 and 4, the operation of the housing support apparatus 10 when the image forming apparatus 1 is installed on the soft floor 3a will be described.

  FIG. 3A is a plan view of the housing support apparatus 10. FIG. 3B is a front view of the housing support device 10. FIG.3 (c) is sectional drawing at the time of cut | disconnecting the housing | casing support apparatus 10 by the cutting line IIIC-IIIC of Fig.3 (a). Here, each sectional view in FIG. 4 to FIG. 8 to be described later is a sectional view when each case supporting device 10 is cut at the position of the cutting line IIIC-IIIC shown in FIG. In addition, in FIGS. 4-8, a top view is abbreviate | omitted.

  As shown in FIG. 3A, the fixing plate 13 is a rectangular plate, and three holes for bolts are provided. The three bolt holes are the hole 13a for the shaft bolt 111, and the two holes 13b and 13c for fastening the bottom of the image forming apparatus 1 to the fixing plate 13 and the adjuster plate 14. . A first female screw having a first pitch is engraved in the hole 13a for the shaft bolt 111, and is screwed into a first male screw engraved in the shaft bolt 111.

  FIG. 3B is a diagram schematically illustrating the state of the housing support device 10 that is separated from the floor 3a. As indicated by the arrow in FIG. 3B, when the user turns the rotating member 123 counterclockwise, both the first support body 11 and the second support body 12 of the housing support apparatus 10 move downward. In that case, the 1st support body 11 moves below the 2nd support body 12 largely according to the ratio of a 1st pitch and a 2nd pitch. FIG. 3C shows how the first support 11 and the second support 12 move downward. In FIG. 3C, the moving distance of the second support 12 including the hollow bolt 121, the torque limiter 122 and the rotating member 123 is almost equal to “0”. On the other hand, the first support body 11 including the shaft bolt 111, the base member 112, and the projection member 113 has the second support body 12 so that a part of the projection member 113 protrudes below the bottom surface of the rotating member 123. It moves more downward.

  FIG. 4A is a diagram illustrating a state in which the casing support device 10 is grounded to the soft floor 3a by further rotating the rotating member 123 leftward. FIG. 4B is a cross-sectional view of the housing support device 10 corresponding to FIG.

  As shown in FIG. 4A, the movement distance of the second support 12 is “h2” with respect to the movement distance “h1” of the first support 11. The ratio between the movement distance h1 and the movement distance h2 is equal to the ratio between the first pitch and the second pitch. As shown in FIG. 4B, a part of the protruding member 113 bites into the soft floor 3a.

  As described above, in the case support device 10, the first support 11 is moved more than the second support 12 by the rotation of the rotation member 123, and a plurality of projecting members are provided below the first support 11. 113 was disposed. As a result, the image forming apparatus 1 can be stably bitten by the housing support device 10 even on a soft floor 3a such as a carpet.

  Next, with reference to FIGS. 5 to 8, the operation of the housing support apparatus 10 when the image forming apparatus 1 is installed on the hard floor 3b will be described. FIG. 5A is a diagram illustrating a state in which the casing support device 10 is grounded to the hard floor 3b by rotating the rotating member 123 of the casing support device 10 leftward. FIG.5 (b) is sectional drawing of the housing | casing support apparatus 10 corresponding to Fig.5 (a).

  As shown in FIGS. 5A and 5B, when the floor on which the image forming apparatus 1 is installed is a hard floor 3b, unlike the soft floor 3a in FIG. The protruding member 113 cannot stably bite the image forming apparatus 1. That is, when the protruding member 113 is made of hard plastic or the like, it slides on the concrete.

  As shown in FIGS. 5A and 5B, when the first support 11 is grounded to the hard floor 3b, the rotating member 123 is rotated more than before the first support 11 is grounded to the hard floor 3b. The rotational load increases. Therefore, the limit value of the torque limiter 122 is set in advance so that the first support 11 detects an increase in the rotational load after the grounding on the hard floor 3b. As a result of setting the limit value of the torque limiter 122 as described above, the torque limiter 122 operates when the rotating member 123 is further rotated leftward after the first support 11 is grounded to the hard floor 3b. By the operation of the torque limiter 122, the torque accompanying the rotation of the rotation member 123 is not transmitted to the first support body 11, and only the second support body 12 rotates. When the rotating member 123 is rotated to rotate the second support 12, only the second support 12 moves downward.

  6 (a) and 6 (b) show that the rotation member 123 is rotated leftward after the first support 11 is grounded on the hard floor 3b, and as a result, the rotation member of the second support 12 is shown. 123 shows a state where 123 is grounded to the hard floor 3b. Since the rotating member 123 of the second support 12 is in contact with the hard floor 3b, the image forming apparatus 1 can be stably fixed by the rotating member 123 having a large friction coefficient.

  As described above, when the first support 11 is first grounded to the hard floor 3b by the rotation of the rotation member 123, the increase in the rotation load after the grounding of the first support 11 is detected and the torque is detected. The limiter 122 is activated. Further, since the second limiter 12 is grounded to the hard floor 3b by the operation of the torque limiter 122, the image forming apparatus 1 can be stabilized by the housing support device 10 even on the hard floor 3b such as concrete. It can be fixed.

  Next, with reference to FIG. 7A, FIG. 7B, FIG. 8A, and FIG. 8B, the operation of releasing the fixation of the image forming apparatus 1 by the housing support device 10 will be described. To do. FIG. 7A is a diagram illustrating a state immediately after the housing support device 10 is separated from the hard floor 3b. FIG.7 (b) is sectional drawing of the housing | casing support apparatus 10 shown to Fig.7 (a). As shown in FIG. 7A, when the rotating member 123 is rotated clockwise, both the first support body 11 and the second support body 12 move upward. In that case, the 1st support body 11 moves upwards rather than the 2nd support body 12 based on ratio of a 1st pitch and a 2nd pitch.

  FIG. 8A is a diagram illustrating a state in which the housing support device is largely separated from the hard floor 3b. FIG.8 (b) is sectional drawing of the housing | casing support apparatus 10 shown to Fig.8 (a). As shown in FIGS. 8A and 8B, the first support body 11 and the second support body 12 move upward in conjunction with each other by rotating the rotating member 123 in the right direction. To do. Furthermore, the 1st support body 11 and the 2nd support body 12 will stop, if it moves to each initial setting position.
