Thus, when the cover 50 is rotated, the attachment screw 45 is exposed to be operable.SELECTED DRAWING: Figure 6

Description

  The present invention relates to a supporting device, and more particularly, to a supporting device including a clamp portion attached to a desk top plate.

  As a supporting device that supports devices such as a monitor on a desk, a supporting device that includes a clamp portion that is attached to a desk top plate is known. The clamp part has a screw mechanism and is fixed to the desk top plate by utilizing the screw mechanism. The screws (mounting screws) of the screw mechanism are provided so that they can be operated from the upper surface side or the lower surface side of the desk top plate. An example of a clamp portion in which a mounting screw is provided on the upper surface side of a desk top plate is disclosed in Patent Document 1, for example.

  When the mounting screw of the clamp portion is provided on the upper surface side of the desk top plate, there is an advantage that the operation is easy. On the other hand, since the mounting screws project on the desk, not only is the appearance unsightly, but problems such as catching occur. Therefore, the mounting screw is covered with a cover. An example of the clamp part in which the mounting screw is covered with a cover is disclosed in Patent Document 2 (FIGS. 6 to 9), for example. A hole for inserting the polygonal handle is formed in the cover of the clamp portion disclosed in Patent Document 2 (FIGS. 6 to 9), and the screw operation can be performed at any time.

Japanese Utility Model Publication No. 47-24206 JP 2000-0555017 A

  Referring to FIG. 1, a supporting device 10 according to an exemplary embodiment of the present invention includes an arm portion 20 and a clamp portion 30. The arm portion 20 has a base portion 202 and a support arm 204 extending obliquely from the base portion 202. A support object (not shown) such as a monitor is attached to a tip portion (not shown) of the support arm 204. The clamp part 30 is fixed to a fixed object (not shown) such as a desk top plate and supports the arm part 20. As a result, the support target is supported above or near the fixed target. As an example, when the clamp part 30 is fixed to the rear edge of the desk top plate, the arm part 20 supports the monitor in front of and above the rear edge of the desk top plate. The arm portion 20 may be fixed to the clamp portion 30, but it is preferable that the arm portion 20 is attached to the clamp portion 30 so as to be rotatable about an axis along the vertical direction. In addition, in the present embodiment, the front-rear direction is the X direction. The + X direction is the front and the -X direction is the rear. Further, the vertical direction is the Z direction. The + Z direction is the upper side and the -Z direction is the lower side.

  As shown in FIG. 1, the clamp portion 30 has a clamp body 40 and a cover 50. Each component forming the clamp body 40 is not particularly limited, but may be made of metal. The cover 50 may be made of resin, although not particularly limited thereto.

  As shown in FIG. 1, the clamp body 40 includes an upper plate 41, a lower plate 42, an intermediate plate 43, a support portion 44, and a mounting screw 45. In addition, the clamp body 40 includes a first connecting plate 46 continuous with the upper plate 41, a second connecting plate 47 continuous with the lower plate 42, and a connection connecting the first connecting plate 46 and the second connecting plate 47 to each other. And a screw 48. In the present embodiment, the number of mounting screws 45 and the number of connecting screws 48 are both two.

  As understood from FIG. 1, the upper plate 41 is a substantially rectangular flat plate that is slightly longer in the lateral direction. In the present embodiment, the lateral direction is the Y direction. The lower plate 42 is also a substantially rectangular flat plate that is long in the lateral direction. However, the dimension of the lower plate 42 in the front-rear direction is shorter than the dimension of the upper plate 41 in the front-rear direction. The upper plate 41 and the lower plate 42 are arranged so as to face each other with a space therebetween in the vertical direction. Further, the upper plate 41 and the lower plate 42 are fixed to each other using a first connecting plate 46, a second connecting plate 47 and a connecting screw 48. However, the present invention is not limited to this. The upper plate 41 and the lower plate 42 only need to be fixed to each other, and their fixing means are not limited. For example, the first connecting plate 46 and the second connecting plate 47 may be welded to each other. Alternatively, a single connecting plate may be fixed to the upper plate 41 and the lower plate 42 by welding or the like. Alternatively, a single metal plate may be bent into a U-shape, and a part thereof may be used as the upper plate 41 and another part may be used as the lower plate 42. However, it is preferable to form the upper plate 41 and the lower plate 42 by separate members as in the present embodiment because the vertical distance between them can be easily changed. For example, a plurality of pairs of connecting screw holes (not shown) arranged in the vertical direction are formed in the first connecting plate 46, and when connecting the second connecting plate 47, a pair of connecting screw holes are selected from the connecting screw holes. By doing so, the distance between the upper plate 41 and the lower plate 42 can be easily changed. Thereby, it is possible to cope with a wider range of thickness of the fixed object.

  As shown in FIG. 1, the support portion 44 is provided on the upper surface 412 of the upper plate 41 so as to project upward from the upper surface 412 of the upper plate 41. The support portion 44 is located at the center in the lateral direction. Further, the support portion 44 is located closer to the front in the front-rear direction. The vertical dimension (height) of the support portion 44 is larger than the vertical dimension (height) of the cover 50. In the present embodiment, the outer shape of the support portion 44 is a tapered columnar shape. However, the present invention is not limited to this. The outer shape of the support portion 44 may be columnar, and may not be tapered or may be polygonal columnar. However, in the present embodiment, in order to facilitate the rotation of the cover 50 around the support portion 44 as described later, it is preferable that the cover 50 has a cylindrical shape or a tapered cylindrical shape.

  The support part 44 also has a mounting part (not shown) for mounting the arm part 20 therein. The arm portion 20 is attached to the support portion 44 using this attachment portion. The mounting portion may be, for example, a nut portion. When the attachment portion is a nut portion, the arm portion 20 is attached to the support portion 44 using a bolt (not shown) that vertically penetrates the support arm 204 and the base portion 202.

  As understood from FIGS. 1 and 2, the upper plate 41 has two screw holes 416 corresponding to the mounting screws 45. The screw hole 416 is formed so as to reach the lower surface 414 (see FIG. 2) from the upper surface 412 of the upper plate 41, that is, to penetrate the upper plate 41 in the vertical direction. These screw holes 416 are provided at symmetrical positions with respect to a plane including the central axis of the support portion 44 and orthogonal to the lateral direction. Further, as shown in FIG. 1, the upper plate 41 is formed with guide grooves 418 that are recessed inward in the horizontal direction at the edges on both sides in the horizontal direction.

  As understood from FIGS. 1 and 2, the middle plate 43 is arranged between the upper plate 41 and the lower plate 42 in the vertical direction. The middle plate 43 has a shape similar to that of the upper plate 41. The size of the middle plate 43 in the front-rear direction and the size of the horizontal direction are smaller than the size of the upper plate 41, respectively. Guide plates 432 are provided on both edges of the middle plate 43 in the lateral direction. The guide plate 432 extends slightly outward in the lateral direction and then extends upward. The guide plate 432 is partially received in the guide groove 418 of the upper plate 41 and guides the vertical movement of the middle plate 43. In other words, the guide plate 432 and the guide groove 418 regulate the movement of the middle plate 43 in the front-rear direction and the lateral movement. In the present embodiment, the middle plate 43 is movable in the vertical direction between the upper plate 41 and the lower plate 42. However, the present invention is not limited to this. The intermediate plate 43 may be movable in the vertical direction within a predetermined range. For example, a hook portion (not shown) may be provided on the upper end of the guide plate 432 to prevent the middle plate 43 from falling off the upper plate 41. In this case, the moving range of the middle plate 43 is limited to a predetermined range by the hook portion.

  As understood from FIG. 2, the vertical dimension (length) of the shaft portion 452 of the mounting screw 45 is considerably larger than the vertical dimension (thickness) of the upper plate 41. Therefore, the mounting screw 45 can be fitted into the screw hole 416 from the upper surface 412 side of the upper plate 41 so as to project downward from the lower surface 414 of the upper plate 41. The mounting screw 45 can be moved in the vertical direction by a screw action, whereby the amount of protrusion of the mounting screw 45 from the lower surface 414 of the upper plate 41 can be changed. The attachment screw 45 restricts the upward movement of the intermediate plate 43 by the tip 454 of which abuts against the intermediate plate 43. Accordingly, when a fixing target (not shown) is present between the middle plate 43 and the lower plate 42, the fixing target can be sandwiched between the middle plate 43 and the lower plate 42.

  As shown in FIGS. 1 and 2, the cover 50 has a flat plate portion 502 and a skirt portion 504 provided around the flat plate portion 502. The flat plate portion 502 and the skirt portion 504 define a housing portion 506 that houses the upper plate 41. In other words, the cover 50 has a housing portion 506 that houses the upper plate 41. The flat plate portion 502 is a substantially rectangular flat plate like the upper plate 41. However, the flat plate portion 502 has a larger dimension than the upper plate 41 in both the front-rear direction and the lateral direction. Further, on the lower surface side of the flat plate portion 502 (the inner surface of the cover 50 facing the upper surface 412 of the upper plate 41), a recess 510 for accommodating the head portion 456 of the mounting screw 45 is formed. Due to the presence of the concave portion 510, the height of the cover 50 can be reduced.

  As shown in FIGS. 1 and 2, the skirt portion 504 is formed so as to surround the periphery of the flat plate portion 502. In the present embodiment, the skirt portion 504 hides not only the upper plate 41 but also the middle plate 43 at least from the front and the lateral directions in a state where the clamp part 30 is attached to a fixing target (not shown). It is configured. Specifically, the skirt portion 504 has a front portion 512 that is provided continuously to the front edge and both side edges of the flat plate portion 502, and a rear portion 514 that is provided at the rear edge. The front portion 512 extends downward or obliquely downward from the flat plate portion 502 and projects upward from the flat plate portion 502. The position of the lower end of the front portion 512 is located below the lower surface of the middle plate 43 in the up-down direction with the middle plate 43 in contact with the mounting screw 45. The rear portion 514 extends downward from the flat plate portion 502 and does not project upward from the flat plate portion 502. The lower end of the rear portion 514 is located below the lower surface 414 of the upper plate 41 in the vertical direction. However, the present invention is not limited to this. The skirt portion 504 may be any one that defines the housing portion 506 that houses the upper plate 41 below the flat plate portion 502. For example, the front portion 512 does not have to project upward from the flat plate portion 502. Further, the lower end of the front part 512 and the lower end of the rear part 514 may be aligned in the vertical direction.

  As can be understood from the drawings of FIGS. 1 to 3, the flat plate portion 502 is formed with a hole 508 corresponding to the support portion 44. When the cover 50 is put on the clamp body 40, the support portion 44 is inserted into the hole 508. By inserting the support portion 44 into the hole 508, the cover 50 can store the upper plate 41 in the storage portion 506. Thus, the cover 50 has the hole 508 into which the support portion 44 is inserted when the upper plate 41 is accommodated in the accommodation portion 506. In the present embodiment, the shape of hole 508 is circular when viewed from above and below. However, the present invention is not limited to this. For example, when the supporting portion 44 is a polygonal prism, the shape of the hole 508 may be polygonal in accordance with the polygonal prism. However, the hole 508 preferably has a circular shape because it facilitates rotation of the cover 50 described later.

  Referring to FIGS. 4 and 5, when the cover 50 is positioned above the upper surface 412 of the upper plate 41, the support portion 44 can maintain the state of being inserted into the hole 508. In this state, the cover 50 can rotate around the support portion 44 as an axis. In other words, the cover 50 is rotatable about the support portion 44 as an axis in a state where the support portion 44 is inserted into the hole 508 and is located above the upper surface 412 of the upper plate 41. In the present embodiment, since the support portion 44 has a tapered shape, the cover 50 can be easily rotated. Even if the outer shape of the support portion 44 is a polygonal column and the shape of the hole 508 is a polygon corresponding thereto, such rotation is possible by making the shape of the support portion 44 a tapered shape.

  As shown in FIG. 6, the shortest distance between the hole 508 formed in the cover 50 and the edge of the cover 50 in the in-plane direction orthogonal to the vertical direction is Ds1. Further, the shortest distance between the support portion 44 provided on the upper surface 412 of the upper plate 41 and the mounting screw 45 fitted in the screw hole 416 of the upper plate 41 is Ds2. In the present embodiment, the position of the hole 508 with respect to the flat plate portion 502 is such that the shortest distance Ds1 between the hole 508 and the edge of the cover 50 is shorter than the shortest distance Ds2 between the support portion 44 and the mounting screw 45 (Ds1. <Ds2) It is set. As a result, as shown in FIGS. 4 and 5, the cover 50 is positioned above the upper surface 412 of the upper plate 41, and the cover 50 is rotated about the support portion 44 as an axis. The head 456 can be exposed to the outside.

  As can be seen from FIG. 1, when the support device 10 is in use, the support part 44 has the arm part 20 attached thereto. The cover 50 cannot be removed from the clamp body 40 when the arm portion 20 is attached to the support portion 44. Further, as understood from FIG. 3, the flat plate portion 502 of the cover 50 covers the upper surface 412 of the upper plate 41 and hides the mounting screw 45 when the upper plate 41 is accommodated in the accommodating portion 506. In this state, it is impossible to operate the mounting screw 45. However, in the support device 10 according to the present embodiment, as described above, the support portion 44 can be rotated with the support portion 44 as an axis in a state where the cover 50 is positioned above the upper surface 412 of the upper plate 41. This rotation is not hindered by the arm portion 20. Further, in the support device 10 according to the present embodiment, the shortest distance Ds1 between the hole 508 and the edge of the cover 50 is set shorter than the shortest distance Ds2 between the support portion 44 and the mounting screw 45. As the cover 50 is rotated, the head 456 of the one mounting screw 45 can be exposed to the outside. In the present embodiment, as shown in FIG. 7, when the cover 50 is rotated 90 °, the head 456 of the mounting screw 45 is exposed. That is, not only when the portion of the cover 50 corresponding to the shortest distance Ds1 and the portion of the clamp body 40 corresponding to the shortest distance Ds2 are overlapped with each other, but also when there is some deviation between them, one mounting screw 45 The head 456 can be exposed to the outside. Thereby, even after the support device 10 is installed, screw operation such as retightening of the mounting screw 45 can be performed.

  As described above, in the supporting device 10 according to the present embodiment, the mounting screw 45 is fitted into the screw hole 416 from the side of the upper surface 412 of the upper plate 41, so that the fixing object such as a desk top plate is mounted from the upper surface side. Work can be performed and the operability of the mounting screw 45 is excellent. Further, since the support portion 44 of the clamp body 40 is inserted into the hole 508 of the cover 50, the support portion 44 is prevented from falling off. Further, the cover 50 is attractive because it accommodates the upper plate 41 and the middle plate 43 in the accommodating portion 506 and hides the mounting screws 45. In addition, since the simple structure of inserting the support portion 44 into the hole 508 is adopted, the cost is also reduced.

  Although the present invention has been described above with reference to some embodiments, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made without departing from the gist of the present invention. For example, although the single middle plate 43 is used in the above embodiment, two middle plates corresponding to the mounting screws 45 may be used. In this case, the two middle plates may be rotatably attached to the tip of the attachment screw 45.
