Abstract

PROBLEM TO BE SOLVED: To provide a means capable of moving a body toward a base smoothly and continuously, and capable of locking and unlocking with little effort.SOLUTION: The support member 1 includes a fixation part 14 for locking the position of the body B to the base S, a rotating support part for movably supporting the body B when the body B is unlocked by the fixation part 14, and a lever rotatably fixed around the axis. When a user applies force to change the vertical direction of the body B, the rotating support part is pressed down with the body B by the downward component of the force, and the fixation part 14 is also pressed down by the press-down force through the lever. On this occasion, the fixation part 14 is displaced with displacement amount greater than the rotating support part by utilizing the principle of lever. As a result, the fixation part 14 is removed and unlocked from the body B, so that the body B can be smoothly moved on a roller 154 of the rotating support part.

Description

  The present invention relates to a mechanism that enables movement of a supported object while supporting the supported object from below.

  Some home appliances such as a display device require a mechanism for adjusting the angle of the main body in the vertical direction and the horizontal direction with respect to the user. The mechanism for adjusting the angle in the vertical direction is called a tilt mechanism, and the mechanism for adjusting the angle in the left-right direction is called a swivel mechanism. Many proposals relating to the tilt mechanism or the swivel mechanism already exist.

  For example, in Patent Document 1, an engagement hole is provided in a mounting table that can freely perform tilt adjustment and swivel adjustment with respect to a base, and tilt adjustment and swivel adjustment are performed by inserting and removing a lock member with respect to the engagement hole. A mechanism for switching between locking and unlocking is described.

  Further, in Patent Document 2, an engagement hole is provided in a slider that moves along a guide groove hole provided in a stand base, and when a user presses down a stopper portion formed integrally with the stand base, the slider is engaged. The stopper convex part of the stopper part fitted in the hole is released and the slider can move with respect to the stand base.When the user releases the stopper part, the stopper convex part fits into the fitting hole and the slider moves. The mechanism of being locked is described.

(Example)
Hereinafter, circulator C using support member 1 concerning one example of the present invention is explained using a drawing.

  FIG. 1 is a perspective view of the circulator C, and FIG. 2 is a front view (FIG. 2 (a)) and a right side view (FIG. 2 (b)) of the circulator C. FIG. 3 is a cross-sectional view of the circulator C. More specifically, FIG. 3A is an EE arrow view of FIG. 2B, and FIG. 3B is a DD arrow view of FIG. 2A.

  As shown in FIG. 2, the circulator C is disposed between the main body B that blows air, the base S that is a support base that supports the main body B from below, and the base S and the base S. And a support member 1 that is a member that provides a tilt adjustment function of the main body B.

  The support member 1 is movably connected to the support member 1 while being placed on the base S. The main body B is placed on the support member 1, and the main body B is connected to the support member 1 so as to be movable along a rail provided on the main body B. Below, the support member 1 concerning a present Example is mainly demonstrated.

  4 is an enlarged view of a portion indicated by a dotted frame G in FIG. 3B, and FIG. 5 is an enlarged view of a portion indicated by a dotted frame F in FIG. 6 is a perspective view of the support member 1 in a state where it is removed from the circulator C. FIG. 7 shows a slider 13 which is a component member fitted into a rail provided in the main body B among the component members of the support member 1. It is a perspective view of the support member 1 of the state removed.

  First, the support member 1 includes a casing 11 that is a box-like body having an upper surface opened. On each of the front side wall portion and the back side wall portion of the casing 11, pillars 12 that are columnar bodies extending upward are attached. The pillar 12 mainly plays a role of securing an interval within a predetermined range between the fixed portion 14 and the rotation support portion 15 (described later) disposed in the casing 11 and the bottom surface of the main body portion B.

  A slider 13 is attached so as to bridge these two pillars 12. The slider 13 is disposed in a shaft hole provided in each of the two pillars 12 and has a shaft bar 131 whose longitudinal direction is the left-right direction, and a roller 132 that is rotatably attached to both ends of the shaft bar 131. , And a bridge 133 that is a substantially plate-like body attached so as to bridge the shaft rod 131 on the near side and the shaft rod 131 on the back side.

  The slider 13 is fitted in a rail having a T-shaped cross section provided on the bottom surface of the main body B, and the movement of the main body B is slid by sliding in the rail when the main body B moves in accordance with the tilt adjustment. It serves to constrain within a predetermined range along the line. The slider 13 has a curved shape viewed from the side so as to fit the curve of the rail provided in the main body B.

  In the casing 11 (see FIG. 7), a fixing portion 14 that is a member for fixing the position of the main body B with respect to the base S is disposed. The fixed portion 14 is biased upward from below by a spring (not shown). Therefore, a part of the fixing part 14 is pressed against the bottom surface of the main body part B in a state where no external force is applied to the main body part B. As a result, it plays a role of fixing the position of the main body B by the frictional force generated between the main body B and the main body B.

  In order to increase the frictional force, rubber sheets 141 are attached to portions where the fixed portion 14 is in contact with the bottom surface of the main body portion B (two places on the left and right in total). The rubber sheet 141 is, for example, a rubber sheet-like body that increases the frictional force and also serves as a cushioning material when the main body part B and the fixed part 14 are in contact with each other.

  Further, in the casing 11 (see FIG. 4), a rotation support portion 15 that supports the main body portion B from below on the bottom surface (outside of the rail) is disposed. First, the rotation support portion 15 includes one shaft rod 151 disposed in the vicinity of the center in the casing 11 so that the left-right direction is the longitudinal direction. At the left end portion and the right end portion of the shaft rod 151, approximately “L” -shaped support rods 152 (four in total) extending respectively toward the front side and the back side are attached to be rotatable around the shaft.

  Each of the four support rods 152 is provided with a shaft hole at each end (the end opposite to the side connected to the shaft 151). A shaft rod 153 is arranged so as to bridge between the shaft holes of the two support rods 152 extending to the front side and between the shaft holes of the two support rods 152 extending to the back side. Has been. A roller 154 is attached to both ends of each of the two shaft rods 153 so as to be rotatable around the shaft. Each of the support bars 152 is urged upward from below by a spring (not shown).

  Here, the strength of these springs is such that the resultant force of the upward force received from below by the front and back rotation support portions 15 is greater than the force by which the main body portion B is pulled downward by gravity. Is selected. As a result, in a state where no external force is applied to the main body part B, the main body part B has the roller 154 (and the rubber of the fixing part 14) of the rotation support part 15 from the lower side to the front side and the rear side. The sheet 141) is supported while being urged from below.

  Further, when the lower surface of the rail of the main body B collides with the roller 132 of the slider 13 as shown in FIG. The roller 132 prevents the upward movement. As a result, the position of the main body B with respect to the base S is sandwiched between the fixed portion 14 and the rotation support portion 15 that push up the bottom surface from below and the slider 13 that works to press down the lower surface of the rail from above. Fixed.

  In the casing 11, as a mechanism for releasing the fixing of the main body part B with respect to the base S and enabling the tilt adjustment, a lever 16 that works to push down the fixing part 14 as the rotation support part 15 is pushed down is provided. Is arranged.

  The levers 16 are respectively disposed in shaft holes provided in the wall portion on the front side and the wall portion on the back side of the casing 11, and the shaft rod 161 whose longitudinal direction is the left-right direction, the shaft rod 161 on the front side, and the back side Each of the shaft rods 161 is provided with a lever rod 162 having one end attached to be rotatable around the shaft.

  The end portion of the front lever rod 162 opposite to the side connected to the shaft rod 161 is disposed on the horizontal rod 142 disposed so as to cross the hollow portion provided inside the fixed portion 14. Has been. Similarly, the end of the back side lever bar 162 opposite to the side connected to the shaft bar 161 is also disposed on the same horizontal bar 142.

  Further, an elliptical hole 163 is provided in the middle position of the shaft rod 161 of the lever bar 162 on the near side, and “L” of the left and right support bars 152 on the near side of the rotation support part 15 is provided in the elliptical hole 163. A horizontal bar 155 arranged so as to bridge around the corner of the character penetrates. Similarly, an elliptical hole 163 is also provided in the middle position of the shaft rod 161 of the lever rod 162 on the back side, and the elliptical hole 163 has the left and right support rods 152 on the back side of the rotation support portion 15. A horizontal bar 155 arranged so as to bridge around the corner portion of the “L” shape passes therethrough.

  As described above, the lever rod 162 arranged so as to be bridged by the fixed portion 14 and the rotation support portion 15 on each of the near side and the rear side is a rotation support portion with the connection position with the shaft rod 161 as a fulcrum. 15 is the connection position with the horizontal bar 155 (position of the elliptical hole 163), and the contact position with the horizontal bar 142 of the fixing portion 14 (the position of the end opposite to the side connected to the shaft bar 161). Brings the action of the insulator as the action point.

  When the user applies a force including a lower component to the main body B by the action of the lever 16, the fixing (locking) of the position of the main body B with respect to the base S by the fixing portion 14 is released. As a result, the user can smoothly and steplessly adjust the vertical angle of the main body B with respect to the base S, that is, the tilt adjustment, within the range along the rail.

  8 to 11 show the support member 1 in a state where a force including a lower component having a predetermined size or more is applied to the main body B by the user (that is, a state where the main body B is pushed down). It is. 8 to 11 correspond to FIGS. 4 to 7, respectively.

  When the user pushes down the main part B (see FIG. 8), first, the rotation support part 15 is pushed down. Accordingly, the horizontal bar 155 of the rotation support unit 15 pushes down the lever bar 162. As a result, the lever bar 162 rotates downward around the axis of the shaft bar 161, and the end opposite to the side connected to the shaft bar 161 pushes down the horizontal bar 142 of the fixed portion 14.

  In addition, since the front lever rod 162 and the rear lever rod 162 rotate independently of each other, when one of the front roller 154 and the rear roller 154 is pushed down by the user's force, The fixing portion 14 is pushed down by the pushed-down lever bar 162.

  When the roller 132 of the slider 13 collides with the upper surface of the rail of the main body B which is pushed down against the upward bias from the rotation support portion 15 and the fixed portion 14 by the user's force, the further The roller 132 prevents the downward movement. As a result, the main body B is in a state of being supported from below by the roller 132 of the slider 13 in contact with the upper surface of the rail while pushing down the rotation support portion 15 by the bottom surface.

  It should be noted that, as shown in FIGS. 8 to 11, when the main body B is pushed down, the fixing portion 14 is automatically separated from the main body B, and the lock is released. Is a point. That is, in the state where the main body part B is pushed down, only the roller 132 of the slider 13 and the roller 154 of the rotation support part 15 are in contact with the main body part B, and these rollers according to the direction of the force applied by the user. The main body B freely moves with respect to the base S within a range along the rail.

  As described above, the reason why the fixing portion 14 is automatically separated from the main body portion B only by the user pushing down the main body portion B is that the distance between the fulcrum and the force point in the lever when the lever rod 162 pushes down the fixing portion 14. This is because the positions are set so that the distance between the fulcrum and the action point becomes longer. When the fulcrum, the force point, and the action point are set as described above, when the rotation support portion 15 is pushed down as the main body portion B is pushed down, the displacement amount of the main body portion B and the rotation support portion 15 is caused by the action of the lever 16. The fixing portion 14 is pushed down with a larger displacement amount. As a result, the fixing portion 14 is separated from the main body portion B.

  After the user finishes moving the main body B, when the user releases his / her hand from the main body B and stops applying the force to the main body B, the main body B moves upward in response to the upward bias of the rotation support portion 15. Then, the state returns to the state shown in FIGS. At that time, since the rubber sheet 141 of the fixing portion 14 comes into contact with the bottom surface of the main body portion B again, the position of the main body portion B with respect to the base portion S is automatically fixed at a position where the user releases the hand from the main body portion B. .

  As described above, according to the support member 1 according to the present embodiment, when the user wants to adjust the vertical angle of the main body B of the circulator C, the user applies a force in the direction in which he wants to move with respect to the main body B. When the angle of the part B reaches a desired angle, it is only necessary to release the hand that has been applying force from the main body part B. At that time, the lock is automatically released with the applied force, and the lock is automatically performed when the applied force is stopped. Further, in the unlocked state, the main body B is supported by the roller, so that the main body B can be moved smoothly.

(Modification)
The embodiment described above can be variously modified within the scope of the technical idea of the present invention. Examples of these modifications are shown below.

  For example, in the support member 1 described above, the rotation support portion 15 (1) supports the main body portion B from below when locked, and (2) when the main body portion B is pushed down, via the lever rod 162. And (3) the role of supporting the main body B from below while permitting the movement of the main body B when the lock by the fixing portion 14 is released. .

  The present invention is not limited to the configuration in which the same constituent members perform all the roles (1) to (3) above, but the configuration in which the roles (1) to (3) are shared by two or more constituent members is adopted. May be.

  FIG. 12 is a diagram schematically showing the mechanism of the support member having such a configuration. Note that the upward arrow in FIG. 12 indicates the direction of urging.

  In the support member according to the modified example, a force applied portion 17 that is in contact with the bottom surface of the main body portion B and is pressed down as the main body portion B is pressed down is provided separately from the rotation support portion 15. In this case, the rotation support portion 15 does not move as the main body portion B is pushed down, and is fixed at a predetermined position.

  In a state in which no force is applied to the main body B (FIG. 12A), the main body B is mainly biased upward by the fixing portion 14 and is locked and supported.

  When the main body B is pushed down by the user (FIG. 12B), the applied force portion 17 is pushed down accordingly, and the lever bar 162 is pushed down. As a result, the fixing portion 14 is pulled away from the main body portion B, and the lock is released. The main body part B that has lost support by the main body part B is supported by the rotation support part 15 and can move on the roller 154 by rolling.

  When the user releases his / her hand from the main part B, the fixing part 14 pushes the main part B upward again, and locking is performed.

  Note that, in the support member according to the present modification, the applied force portion 17 is always in contact with the bottom surface of the main body portion B, so that when the main body portion B moves in accordance with the tilt adjustment, It is necessary to select the materials and shapes of the surfaces so that the frictional force with the force portion 17 does not increase.

  As another modification, a configuration in which the above-described support member 1 is turned upside down may be employed. In other words, the support member 1 described above is disposed between the base S and the main body B so that the fixed portion 14 and the rotation support portion 15 are in contact with the main body B. Instead of this, the support member 1 may be disposed between the base S and the main body B so that the fixed portion 14 and the rotation support portion 15 are in a direction in contact with the base S. In that case, the support member 1 is connected to the main body B so as not to move, and is connected or contacted to the base S so as to be movable.

  FIG. 13 is a diagram schematically showing the structure of a spherical object G1 with a stand that employs the support member 1 according to such a modification. First, the spherical object G1 with a stand includes a base S and a support member 1A disposed on the base S so as to be immovable, as in the above-described embodiment. On the support member 1A, a main body B1 and a hollow hemispherical container B2 which are supported objects for the support member 1A are placed. A rail is provided on the bottom surface of the container B2, and the container B2 can move in the vertical direction (the direction of the arrow X) along the rail as in the above-described embodiment.

  The main body B1 is attached to the container B2 so as to be rotatable around the axis of the appropriately bent shaft bar H (in the direction of arrow Y) provided in the diameter direction. A support member 1B is attached on the surface of the main body B1 facing the container B2. The support member 1B has a structure in which the pillar 12 and the slider 13 are removed from the support member 1 in the above-described embodiment. Further, the support member 1B is disposed in such a direction that the fixed portion 14 and the rotation support portion 15 are in contact with the container B2, and is fixed to the main body B1 so as not to move.

  According to the spherical object G1 with a stand configured as described above, the support member 1A is unlocked according to the vertical force applied to the user's main body B1, and the tilt adjustment is possible, and the user's horizontal force applied to the main body B1. Accordingly, the lock of the support member 1B is released and the swivel adjustment is possible.

  As still another modification, a spherical object G2 with a stand having a structure schematically shown in FIG. 14 is also conceivable. In the spherical object G2 with a stand, a plurality of support members 1C are attached to a hollow hemispherical container included in the base S, and a spherical main body B2 is placed on the support members 1C.

  The support member 1C has a structure in which the pillar 12 and the slider 13 are removed from the support member 1 in the above-described embodiment. Further, in the support member 1 </ b> C, a ball bearing is employed instead of the roller 154 of the rotation support portion 15. That is, the rotation support portion of the support member 1C supports the main body B2 so as to be movable in any direction of 360 degrees in the unlocked state.

  According to the spherical object G2 with a stand having such a configuration, the user rotates the main body B2 in an arbitrary direction by applying a force to the main body B2 in an arbitrary direction, and the main body at an arbitrary position. By releasing the hand from B2, the main body B2 can be fixed at that position.

  As yet another modification, a configuration is adopted in which the fixed portion 14 is moved by a displacement amount larger than the displacement amount of the rotation support portion 15 (or the force-receiving portion 17 independent of the rotation support portion 15) by another mechanism that does not depend on the lever. May be. FIG. 15 is a diagram schematically showing a configuration of a modified example in which a gear mechanism is employed instead of the lever 16.

  The support member 1 according to this modification includes a gear mechanism 18 instead of the lever 16. The gear mechanism 18 includes a rack 181 provided on a side surface of the rotation support portion 15, a spur gear 182 that meshes with the rack 181, a spur gear 183 that meshes with the spur gear 182, and a spur gear 183 that meshes with each other and a fixed portion. 14 is provided with a rack 184 provided on the side surface.

  When the rotation support portion 15 is pushed down as the main body portion B is pushed down, the rack 181 moves downward, the movement is transmitted to the rack 184 via the spur gear 182 and the spur gear 183, and the fixing portion 14 is pushed down. .

  Here, for example, the pitch (interval between teeth) of the rack 181 and the rack 184 is the same, but the number of teeth of the spur gear 182 is larger than the number of teeth of the spur gear 183. Therefore, the rotation angle of the spur gear 183 is larger than the rotation angle of the spur gear 182, and the displacement amount of the rack 184 is larger than the displacement amount of the rack 181.

  Alternatively, for example, the same result can be obtained even if the spur gear 182 and the spur gear 183 have the same number of teeth and the pitch of the rack 184 is wider than the pitch of the rack 181.

  In addition, the quantity, shape, position, etc. that specify each component of the support member 1 in the above-described embodiment and its modifications are merely examples, and other quantities, shapes, positions, etc. are adopted depending on the application. Also good.

  For example, in the above-described embodiment, a configuration in which the fixing portion 14 is disposed between the near-side roller 154 and the back-side roller 154 is employed, but the fixing portion 14 is positioned outside the rollers 154. The arrangement can be variously changed.

  Moreover, when the part which the main-body part B touches the fixing | fixed part 14 is a magnetic body, the structure which uses a magnet for the fixing | fixed part 14 may be employ | adopted for the purpose of improving the fixing capability by the fixing | fixed part 14. FIG. In that case, the main body B can be more firmly fixed by the magnetic force in addition to the frictional force.

  Furthermore, when using a magnet for the fixing | fixed part 14, the structure which makes the magnet an electromagnet and supplies electric power with respect to the said electromagnet only at the time of a lock | rock may be employ | adopted. In that case, since the magnetic force does not work at the time of unlocking, the main body B can be moved more smoothly as compared to the case where the magnetic force works at the time of unlocking.

  Moreover, in the Example mentioned above, although the example which the main-body part B moves along a curved surface with respect to the base S was demonstrated, the support member 1 is the structure in which the main-body part B moves along a plane with respect to the base S. May be used.

  According to the support member of the present invention, the position and angle of the main body relative to the base can be adjusted smoothly and easily. Therefore, since it can be employed in various products such as home appliances and toys, it is manufactured and sold in large quantities and can be used in service industries such as so-called manufacturing and retailing.
