Description

  The present invention is provided on the back side of a partition member that is an image display device such as a liquid crystal display or a plasma display, and a partition member that includes a photo frame (including a device that leans a painting or the like on the installation surface) or a figure (mirror stand). The present invention relates to a stand structure for a partition member in which a tilting stand is arranged and the partition member has a predetermined inclination angle.

  Conventionally, an image display device such as a liquid crystal display or a plasma display is provided with an inclination stand on the back side thereof, and an inclination angle of the image display device with respect to the installation surface is adjusted to a predetermined angle by adjusting an opening angle with respect to the image display device. There is something to do. As an image display device, a plasma display such as a display for a computer and a liquid crystal display are widely used. However, in recent years, a small and thin liquid crystal television which is easy to carry and sometimes used as a wall hanging is also rapidly used. It is becoming popular. On the other hand, the screen stands (including those that stand a picture on the installation surface) and screens (mirror stands) are also provided with an inclination stand on the back side, so that the inclination angle with respect to the installation surface is increased. Some have a predetermined angle.

  As the stand structure of the partition member, there is provided a partition member standing at a predetermined angle with respect to the installation surface, and a tilting stand disposed on the back side of the partition member, and the opening of the tilting stand with respect to the partition member The inclination angle of the partition member with respect to the installation surface is set to a predetermined angle by adjusting the angle. As a stand structure in the case of the liquid crystal display, as shown in FIGS. 10 and 11, a hinge part (rotating shaft) 20 h for adjusting the tilt angle (tilt angle) of the liquid crystal display L is provided horizontally on the back surface of the liquid crystal display L. In addition, the first and second springs b1 and b2 are wound around the hinge portion 20h and connected to the tilting stand 11 in many cases. The first and second springs b1 and b2 obtain a biasing force in the tilt direction in which the tilt angle of the liquid crystal display L increases with respect to the hinge portion 20h (repels the weighting force of the liquid crystal display L). A pair of b1 is attached, and a pair of second springs b2 for obtaining an urging force with respect to the vertical direction in which the inclination angle of the liquid crystal display L is reduced (repels a load force in a direction in which the inclination stand 11 is folded) are attached. Yes. In the hinge portion 20h, a friction spring is also attached to the rotating shaft. As a support structure for a stand in which the first and second springs b1 and b2 are wound around the hinge portion 20h, there is Patent Document 1 or the like.

  Further, the apparatus includes a main body foot 2 attached to the liquid crystal display side and a support foot attached to the liquid crystal display so as to be rotatable, and biasing force to a (rubber) roller rotatably attached to the main body foot 2 Is provided with a spring that makes the roller non-rotatable and a brake release member that makes the roller rotatable by applying a force against the urging force of the spring (Patent Document 2). In Patent Document 2, the roller is rotatable by applying a force against the biasing force of the spring by the brake release member, and the main body foot is moved with respect to the installation surface.

On the other hand, a partition member such as a photo stand or a figure stand (mirror stand) generally employs a simpler structure than the stand structure in the image display device. That is, as shown in the conventional examples of Patent Document 1 and Patent Document 2 (Patent Document 1 shows the conventional example shown in FIGS. 7 and 8, and Patent Document 2 shows the conventional example shown in FIGS. 11 and 4). The structure is such that a U-shaped tilting stand to which a rubber roller or the like is attached is rotatably attached to the back side of the partition member at its U-shaped tip.

  However, in the conventional example as shown in FIGS. 10 and 11, when the tilting stand 11 is separated from the installation surface, the tilting stand is at a position where the urging forces of the first spring b1 and the second spring b2 are balanced. 11 remains open (when the screen of the liquid crystal display L is directed toward the installation surface, the tilting stand S remains obliquely open), which may interfere with the transportation (open) In other words, it is necessary to prevent the tilting stand from hitting the peripheral device or the like), and there is a problem in the case of packing. Further, in the case of the conventional spring structure, when the display screen of the display L becomes larger or the weight becomes heavier, the larger one must be used in order to maintain a large biasing force of the spring. Therefore, it is necessary to set the spring (first spring b1) in consideration of the load force accompanying the load, and accordingly, it is difficult to adjust the urging force balance between the first spring b1 and the second spring b2, and the liquid crystal There are problems such as having to adjust for each type and size of the display L and increasing the sound of the springs. That is, in the above-described conventional example, in the inclination direction in which the inclination angle of the partition member such as the liquid crystal display L is increased with respect to the installation surface (hereinafter also referred to as “laying posture direction”), the screen is returned to the vertical direction in which the inclination angle is reduced. This is performed against the first spring b1. However, since a friction spring is also attached to the hinge portion 20h, when the angle in the laying posture direction increases, the hinge spring 201 resists the first spring b1 trying to return to the vertical direction. The force to be applied gradually increases, and the maximum force is required in a complete sleeping position (screen parallel to the desk surface). When the weight and size of the liquid crystal display L are increased, it is difficult to adjust the liquid crystal display L, and it is also very difficult to adjust the force when operating by hand.

  Next, in Patent Document 2, in the vertical direction in which the tilt angle of the display is small (hereinafter also referred to as “vertical posture direction”), the main body foot is moved with respect to the installation surface by operating as described above. Since the inclination angle with respect to the display installation surface is adjusted by changing the relative position of the main body foot with respect to the foot, the closer to the vertical posture, the greater the pressing force by the hand. In other words, it is necessary to press the strut foot toward the body foot with the brake release member held with your finger, and the closer the strut foot is to the body foot, the greater the pressing force by the hand. It is difficult to adjust the power. In addition, in the laying posture direction, as in the conventional example, the force applied against the spring that returns to the vertical direction gradually increases, and in the full laying posture (screen parallel to the desk surface), the maximum force is obtained. Is required. When the weight and size of the liquid crystal display L are increased, it is difficult to adjust the liquid crystal display L, and it is also very difficult to adjust the force when operating by hand.

  On the other hand, in recent years, small-sized liquid crystal televisions that are easy to carry are becoming widespread. However, in the conventional stand structure, the tilting stand 11 remains open as described above, so that it can be used as a wall-mounted television. It is not possible to hang the wall by pressing the entire back side of the wall to the wall (it is impossible to hang the screen parallel to the wall), and when using the liquid crystal display as a touch panel There is a problem that the laying posture becomes thick or tilted.

  Accordingly, an object of the present invention is to provide a force greater than a predetermined pressing force when the partition member such as an image display device is operated by pressing the partition member with a hand in an inclination direction in which the inclination angle is large with respect to the installation surface. It is possible to obtain an inclination angle for the first time when the pressure is applied, and after the initial operation of the spreading operation, a gradually increasing pressing force or the like as in the conventional example is not required, while the inclination angle of the partition member is In the vertical direction, where the tilting stand becomes smaller, the tilting stand's own weight can be used to reduce the closing operation of the tilting stand by hand as much as possible, and the tilting stand remains open even when it is separated from the installation surface. An object of the present invention is to provide a stand structure for a partition member that does not become a problem.

  The stand structure for a partition member according to claim 1 of the present invention includes a partition member standing at a predetermined angle with respect to the installation surface, and a tilting stand disposed on the back side of the partition member, and the tilting stand. In the stand structure of the partition member in which the inclination angle of the partition member with respect to the installation surface is set to a predetermined angle by adjusting the opening angle with respect to the partition member, a bracket for obtaining a connection state with the tilt stand, and a one-way fixed to the bracket The clutch is connected to the one-way clutch and has a hinge part attached to the back of the partition member to serve as a fulcrum for the rotation of the tilt stand. The one-way clutch has a large tilt angle of the partition member for adjusting the angle of the tilt stand. In a tilting direction, when the stopping torque works and the angle is maintained, a force greater than the stopping torque is applied. Parts rotate, while in the vertical angle of inclination becomes small shielding member idles the hinge portion acts its own weight of the tilt stand, characterized in that it is angle adjustment.

  The stand structure of the partition member according to claim 2 of the present invention includes a partition member standing at a predetermined angle with respect to the installation surface, and a tilting stand disposed on the back side of the partition member. In the stand structure of the partition member that adjusts the opening angle of the stand with respect to the partition member so that the inclination angle of the partition member with respect to the installation surface is a predetermined angle, the bracket is secured to the bracket and the bracket to obtain a connection state with the tilt stand. A one-way clutch, a hinge portion that is connected to the rear surface of the partitioning member and is connected to the one-way clutch, and a friction spring attached to the hinge portion. In the one-way clutch, the stopping torque works in the tilt direction where the tilt angle of the partition member increases, and the angle is maintained. When a force exceeding the stopping torque is applied, the hinge is rotated against the friction spring. It is characterized by being adjusted.

  According to these inventions, when the partition member is changed from the nearly vertical state to the inclination direction in which the inclination angle increases, the stopping torque is applied to the one-way clutch, and therefore the stopping torque of the one-way clutch is applied to the stand for inclination. Since the inclination angle of the partition member cannot be changed unless it is expanded with a force equal to or greater than the stopping torque, the inclination stand does not easily expand. In this aspect, the friction spring is attached to the hinge portion, and the hinge portion is rotated against the friction spring when a force greater than the stopping torque is applied. The friction spring does not obtain an urging force with respect to the inclination angle of the partition member as in the conventional example, but plays a role of preventing the hinge portion from idling. On the other hand, when the partition member is set to a vertical posture with the lower end side of the partition member as a fulcrum, the tilting stand is self-weighted and is automatically closed to the partition member side. This is because the one-way clutch is free, that is, idles with the hinge portion when the inclination angle of the partition member is vertical. When the partition member is lifted, the lower end of the tilting stand is separated from the installation surface, and its own weight acts in the closing direction of the partition member.

  The stand structure of the partition member according to claim 3 of the present invention is based on the invention according to claim 1 or claim 2, and is engaged with a locking projection that locks the back surface of the partition member and the inclined stand. A locking recess is provided relatively, and the tilting stand stops opening and closing at a predetermined angle with respect to the partition member. When this stop position is exceeded, the locking projection and the locking recess are unlocked. It is characterized by being.

  According to the present invention, when the partition member is moved from the nearly vertical state to the inclination direction in which the inclination angle is increased, the engagement protrusion and the engagement recess are engaged, and the inclination stand is temporarily stopped during the opening / closing operation. When the stop position is exceeded, the locking projection and the locking recess are unlocked, and then again expand. On the other hand, when the partition member is placed in a vertical posture with the lower end side of the partition member as a fulcrum, the weight of the tilting stand is applied and it automatically closes to the partition member side. The recess is locked, and the tilting stand is temporarily stopped in the middle of its closing operation. When this stop position is exceeded, the locking projection and the locking recess are unlocked, and the tilting stand is closed again. Therefore, it does not close at a stretch. Even if the partition member is lifted, the tilting stand automatically closes due to its own weight, but in this case also, the locking projection and the locking recess are locked during the closing operation, and the tilting stand Since it stops once in the middle of the closing operation, it does not close suddenly.

  In the stand structure of the partition member according to claim 4 of the present invention, on the premise of the invention according to claim 1 or 2, a roller that rotates by sliding contact with the installation surface is attached to the lower end side of the tilt stand. It is characterized by.

  According to the present invention, when the partition member is changed from the nearly vertical state to the tilt direction in which the tilt angle is increased, in the initial operation, the lower end of the partition member is not moved with one hand (the lower end of the partition member is When the tilting stand is opened with the other hand), a roller that rotates by sliding contact with the installation surface is attached to the lower end of the tilting stand when pushed by hand from the front side of the partition member. As a result, it assists the expansion operation. In this case, the pressing on the front side is performed with a force equal to or greater than the stopping torque at which the stopping torque of the one-way clutch is applied. On the other hand, when the partition member is set to a vertical posture with the lower end side of the partition member as a fulcrum, the weight of the tilting stand is applied and the partition member automatically closes to the partition member side. In this case, the roller assists the closing operation. The roller can be attached to the lower end of the partition member or both the lower end of the partition member and the lower end of the tilting stand.

  The stand structure of the partition member according to claim 5 of the present invention is an image display device such as a liquid crystal display or a plasma display on the premise of the invention according to claim 1 or 2, and is arranged on the back side of the image display device. When the tilt stand is closed, the flat flat surface on the back side of the image display device and the flat flat surface of the tilt stand are flush with each other, and the tilt stand is on the back side of the image display device. It is characterized by being paid.

  According to this invention, when the tilting stand is closed, the flat surface of the back frame and the flat surface of the tilting stand are flush with each other. In this case, the tilting stand does not protrude as in the conventional case, and it is possible to hang the display screen in contact with the wall, and it can be used in a flat state in which the display screen is in contact with the desk surface. Etc. are also possible. Further, since there is no portion where the tilting stand protrudes from the partition member, there is no situation where it collides with a peripheral device when carrying it.

  According to the stand structure of the partition member of the present invention, when the one-way clutch is used and the force greater than the stop torque is applied from the state in which the stop torque is applied in the tilt direction in which the tilt angle of the partition member becomes large, the hinge portion Therefore, the tilting angle of the tilting stand is expanded only when a force exceeding a predetermined level is applied when pressing it from the front side of the partition member by hand, and after the initial operation of the expanding operation, The operation becomes possible with a substantially constant force without requiring a gradually increasing pressing force or the like as in the conventional spring. On the other hand, in the vertical direction where the inclination angle of the partition member becomes small, the weight of the tilting stand acts in the closing direction, so that it is possible to reduce manual operation in the vertical posture direction. In addition, by adopting a structure in which a locking projection and a locking recess that are locked to each other are provided relatively, particularly in the closing operation, the tilting stand stops temporarily in the middle of the closing operation. It wo n’t close at once. In addition, the tilting stand will never remain open when carrying or packing.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, FIG. 2 and FIG. 3, in this embodiment, a liquid crystal display L1 having a 17-inch liquid crystal screen L1a constituted by a flat plane is applied as a partition member. An inclination stand S for obtaining a predetermined inclination when placed on a desk surface or a table is attached to the back surface of the apparatus via a hinge portion H.

  The main body of the liquid crystal display L1 is incorporated in a synthetic resin frame F in which the front side frame F1 and the back side frame F2 are combined. The front side frame F1 is formed with a front-side opening through which the liquid crystal screen L1a of the liquid crystal display L1 is exposed, and the back side frame F2 is a thick part F2a having a large width so that the upper side covers the rear side of the liquid crystal display L1. The lower side has a narrow portion F2b whose width is reduced via a stepped portion F2c with the thick portion F2a. A hinge cover Hc is formed between the upper thick part F2a and the lower narrow part F2b, that is, in the center of the step part F2c in the width direction, and the hinge part H is attached in the hinge cover Hc. . The thick part F2a and the narrow part F2b of the back frame F2 are formed as a flat surface F2p having a flat surface. When the liquid crystal display L1 is hung on the wall, the liquid crystal screen L1a is mounted on the wall in parallel. Is possible. That is, as will be described later, the back side of the tilting stand S is also a flat surface Sra. When the tilting stand S is closed, the tilting stand S is stored below the thick portion F2a on the back side of the image display device. The flat surface F2p on the back side of the flat plate and the flat flat surface Sra of the tilting stand S are flush with each other so that the liquid crystal screen L1a can be mounted on the wall surface in parallel. Below the frame F, a leg portion Fk in contact with the installation surface is formed in a convex shape, and the tip of the leg portion Fk is formed in a semicircular arc shape. A rubber (not shown) is attached to the back side of the leg Fk from the center position of the semicircular arc toward the rear, and when the leg Fk is tilted backward by a predetermined angle, The rubber is in contact with the installation surface so that the installation surface is not damaged and is devised so as not to be displaced with respect to the installation surface.

  A pair of left and right locking holes 8a are formed in the leg portion Fk (FIG. 2). The locking hole 8a is configured such that the locking piece 8b of the tilting stand S is locked and the tilting stand S is locked to the back side of the leg portion Fk of the liquid crystal display L1. Therefore, the situation which opens when carrying up and carrying out packing is prevented.

  A locking projection 9a is provided on the narrow portion F2b of the back frame F2 (FIG. 7). The locking projection 9a comes into contact with the locking recess 9b on the tip side Sa of the tilting stand S when the tilting stand S expands to a predetermined angle. As will be described later, the tilting stand 9a. When the opening angle of S with respect to the partition member is expanded by a predetermined angle (about 40 degrees), the abutment operation is stopped once, and the expansion operation is stopped. It has become so. When the tilting stand S is expanded, the predetermined position is set so that the predetermined tilt angle is known at the stop position (as an indication of the expansion angle), and when the tilting stand S is closed, it is not closed suddenly. It is for doing so. Here, in order to obtain the temporarily stopping operation as described above, as shown in FIG. 8, while providing the locking projection 10r on the stepped portion F2c of the back frame F2, the leaf spring 10 is attached to the tilting stand S, The locking recess 10b at the tip of the leaf spring 10 may be locked with the locking projection 10r. In the example shown in FIG. 8, when the locking recess 10b comes into contact with the locking projection 10r, the elastic force acts to make a clicking sound, and this sound also has a predetermined angle during the opening / closing operation. Can be understood.

  The tilting stand S is a box type in which the front cover Sf and the back cover Sr are overlapped, and the upper side (front end Sa) and the lower side (rear end Sb) in which the front side cover Sf and the rear side cover Sr are overlapped. Each exhibits a semicircular arc shape. Further, the upper side in the box shape is formed in a U shape, and the hinge cover Hc is surrounded by the U-shaped tip portion. The one-way clutch 1 is attached together with the bracket 2 at the U-shaped tip. The outer sides of the box-shaped front cover Sf and the back cover Sr are flat surfaces, and the flat surface Sra of the back cover Sr is an inclination stand S in which the front cover Sf and the back cover Sr are overlapped. Is closed with respect to the narrow width portion F2b of the back frame F2 (when the tilting stand S is brought closer to the leg portion Fk), it becomes flush with the flat surface F2p of the back frame F2. The width when viewed from the back side of the box-shaped tilting stand S is narrower than the width of the leg portion Fk, but the width when combined with the rubber rollers that protrude from the left and right is the convex shape. The width is the same as the width of the leg portion Fk. For this reason, in terms of appearance, when the tilting stand S is brought closer to the leg portion Fk, the tilting stand S is integrally recognized with the leg portion Fk.

  The hinge portion H adjusts the tilt angle (also referred to as “tilt angle” or “elevation angle”) of the liquid crystal display L1, which is a partition member, and is attached to the frame F (back side frame F2) so as to be hidden by the hinge cover Hc. (FIG. 3). That is, the hinge portion H is arranged in a pair of left and right, and includes a pair of rotating shafts 6, a pair of L-shaped fixing plates 7 that fix the rotating shaft 6, and a pair of friction springs 5. . The pair of fixed plates 7 are integrally attached to the frame F (the back frame F2), and the pair of rotating shafts 6 are rotatably attached to the pair of fixed plates 7. However, it is arranged via the friction spring 5 in order to restrict the rotation shaft 6 from idling. The friction spring 5 plays a role of regulating the friction spring 5 so that it does not rotate unless it is a force with a force equal to or greater than the stopping torque of the one-way clutch 1 described later. A washer is attached to the outside of the friction spring 5.

  The one-way clutch 1 and the bracket 2 are integrally attached to the pair of rotating shafts 6 of the hinge portion H as shown in FIGS. The bracket 2 has a fitting hole 2a into which the one-way clutch 1 is fitted, and contact portions 2b that come into contact with the inner side of the front cover Sf and the inner side of the rear cover Fr. The front cover Sf and the rear cover Fr are connected to each other. When overlapped, the contact portion 2b of the bracket 2 is clamped inside each. Note that the abutting portion 2b is only fixed to the inside of the front cover Sf with a screw N (FIGS. 4 and 7). As shown in FIGS. 5 and 6, the one-way clutch 1 is fitted into a fitting hole 2 a formed in the bracket 2, and the bracket 2 obtains an integral connection state with the tilting stand S. Note that the one-way clutch 1 may be fastened to the bracket 2 as long as an integrally connected state can be obtained. In the present embodiment, the bracket 2 rotates in a predetermined direction, that is, the restraining torque works in an inclination direction in which the inclination of the partition member (liquid crystal display L1) increases, but the inclination stand S is inclined in a direction in which the force exceeds the stopping torque. The rotating shaft 6 of the hinge portion H rotates against the friction spring 5 only when it is expanded. The tip of the rotating shaft 6 of each hinge portion H protrudes from the hinge cover Hc and is attached via the one-way clutch 1 to the fitting holes 2a of the pair of brackets 2 attached to the left and right sides of the U-shape. Although the one-way clutch 1 is a commercially available one called a bearing type, a coil spring type one-way clutch is also commercially available, and both of them can be applied. For example, as shown in FIG. 6, the so-called bearing system includes a roller holder W1 that holds a rotating roller (bearing) Wr, and an outer frame body W2 to which the roller holder W1 is fitted. The rotating shaft 6 of the hinge part H is placed in these cylinders. The roller Wr is attached to the roller holder W1 at a predetermined interval on the circumference, and is moved toward one side of the roller housing hole Ws of the outer frame body W2 by a spring (not shown) to restrict the rotation of the roller Wr. A gap is formed on the side, and the rotation of the roller Wr is allowed. That is, the roller Wr rotates in one direction but does not rotate in the other opposite direction. In the present embodiment, when the bracket 2 that operates together with the tilting stand S rotates about the rotation shaft 6 of the hinge portion H (when the tilting stand S expands), the roller (bearing) Wr is For this reason, the rotating shaft 6 rotates against the friction spring 5 and the tilting stand S is expanded. On the other hand, when the tilting stand S is closed, the roller (bearing) Wr rotates, that is, idles with the rotating shaft 6 of the hinge portion H (free), so that the tilting stand S rotates in the closing direction by its own weight. To do. The rotating shaft 6 is normally restricted by the friction spring 5 and rotates with a force equal to or greater than the stopping torque of the one-way clutch 1 as described above. It only rotates. Further, in the coil spring type one-way clutch, there is a possibility that the hinge portion H becomes large, and there is a fear that the connecting portion with the hinge portion H of the tilting stand S is large, and the operation is not easy. Such a bearing system is preferable.

  Below the tilting stand S, a rubber roller (rubber roller) g is attached to the idle shaft J (FIG. 4). The rubber roller g is rotated by contact with the desk surface when adjusting the opening / closing angle of the tilting stand S with respect to the partition member L1, and assists the opening and closing operation and does not damage the desk surface. It is provided to ensure that The rubber roller g and the idle shaft J also serve as a kind of weight for exerting its own weight on the lower end of the tilting stand S. Note that the roller (rubber roller) g that rotates by sliding contact with the installation surface can be attached to the lower end side of the leg portion Fk.

  The lower end of the tilting stand S comes into contact with the installation surface together with the lower end of the leg portion Fk below the frame F when the frame F is in a vertical posture. That is, even if the liquid crystal display L is placed in a vertical posture with the leg portion Fk as a fulcrum or in a flat posture (laying posture) having the largest inclination angle, the tip of the leg portion Fk and the tip Sa of the tilting stand S are aligned. Either will not protrude.

  Next, a case will be described in which the liquid crystal display L1, which is a partition member, is taken out of the packaged state and placed on a desk or table using this embodiment.

  First, in the state packed in the cardboard box, the tilting stand S can be stored in a small size if it is superimposed on the back side of the liquid crystal display L1. In this case, the locking hole 8a and the lock piece 8b are locked and locked. The flat flat surface F2p on the back side of the liquid crystal display L1 and the flat flat surface Sra of the tilting stand S are flush with each other, and the tip of the leg and the tip Sa of the tilting stand S have the same length. This is because they are aligned.

  When the liquid crystal display L1 is taken out of the cardboard box and placed on the desk surface, the tilted stand S in the closed state is unlocked and supported in a vertical posture with the leg portion Fk of the liquid crystal display L1 as a fulcrum. Then, the tilting stand S is expanded to the back side such as a desk surface. Such expansion work may be performed only in the initial state, and thereafter, the frame F is pressed from the front side of the liquid crystal display L1 to the back side such as a desk surface. When pressed from the front side, the rubber roller g rotates to expand the tilt stand S in the tilt direction in which the tilt angle of the liquid crystal display L1 increases. In such an expansion operation, since the restraining torque is acting on the one-way clutch 1 in relation to the hinge portion H, the one-way clutch 1 needs to be spread with a force greater than the restraining torque. The rotation of the rotary shaft 6 of the rotary hinge portion H is regulated by the friction spring 5, but when the front shaft is pressed so that a force greater than the stop torque acts, the rotary shaft 6 rotates against the friction spring 5. Thus, the tilt angle of the liquid crystal display L1 is changed. That is, since the friction spring 5 is attached to the rotating shaft 6, the rotating shaft 6 is rotated by applying a force against the friction spring 5. Accordingly, it is possible to recognize whether the initial rotational force is increased or not, and there is no risk that the operator will unintentionally cause the expansion beyond the allowable range.

  Here, in the middle of the expansion operation, it is temporarily stopped at the expansion position of about 40 degrees (FIGS. 7 and 8). This is because the locking recess 9b on the front end side Sa of the tilting stand S comes into contact with the locking projection 9a of the leg Fk. This is because in the example shown in FIGS. 8A and 8B, the locking recess 10b at the tip of the leaf spring 10 is elastically deformed so as to get over the locking projection 10r, and then locked with the locking projection 10r. If it further extends beyond such a temporary locking position, the tilting stand S comes into contact with the step portion F2c of the back frame F2 and stops the expansion operation. This position is the position where the tilting stand S is most expanded, and in this embodiment, the liquid crystal screen L1a of the liquid crystal display L1 rotates about 90 degrees with respect to the back frame F2, and the liquid crystal screen L1a is about about the installation surface. Take a 45 degree inclination.

  On the other hand, contrary to the above operation, when returning the liquid crystal display L1 to the vertical direction in which the tilt angle is small, the liquid crystal display L1 is placed in a vertical posture with the leg Fk as a fulcrum by placing a hand on the frame F, etc. In this closed state, the rubber roller g rotates and automatically closes to the leg portion Fk side of the liquid crystal display L by the weight of the tilting stand S, and can be returned to the vertical direction. In other words, the one-way clutch 1 rotates idly (free) with respect to the rotating shaft 6 of the hinge portion H due to its own weight or its own weight due to the load from the shaft J or the rubber roller g. Accordingly, the tilting stand S is drawn toward the leg Fk. However, during the closing operation, the wing is temporarily stopped at a closing position of about 40 degrees. In such a temporary stop position, the liquid crystal screen L1a of the liquid crystal display L1 has an inclination posture of about 50 degrees with respect to the installation surface, so that this position can be set as a viewing angle, but it is more nearly vertical. For example, when the tilting stand S is lightly pressed from the back side Sr, the locking projection 9a and the locking recess 9b are unlocked, and the tilting stand S comes into contact with the back side of the leg Fk. The stand S is closed. This position is the position where the tilting stand S is most closed, and these movements are assisted by the rubber roller g. When completely closed in this way, the flat surface F2p of the back frame F2a and the flat surface Sra of the tilting stand S are flush with each other.

  Next, in the case of carrying, if the above-mentioned closing operation is performed, or the liquid crystal display L1 is lifted from the installation surface and the liquid crystal display L1 which is a partition member is tilted in the direction of closing the tilting stand S, The stand S is automatically closed by its own weight. However, also in this case, in the middle of the closing operation, the suspension is temporarily stopped at the closing position of about 40 degrees, and suddenly restricts the tilting stand S from closing to the leg Fk side. There is no danger such as pinching a finger between Fk, and if the lock piece 8b is finally locked in the locking hole 8a for safety when carrying it, the tilt stand S is inadvertently locked. There is no need to worry about opening, it can be easily packed in a small cardboard box, etc., and it has an excellent packing posture.

  In the above embodiment, the rubber roller g is attached to the tilting stand S. However, the rubber roller g can be attached to the leg portion Fk of the liquid crystal display L1 via a shaft. The rubber roller g rolls on the desk surface or the like in the above-described expansion operation or closing operation so as not to damage the desk surface or the like when assisting the opening / closing operation. However, the rubber roller g does not damage the leg portion Fk of the liquid crystal display L1. Even if the rubber roller g is attached, there is no particular problem in the opening / closing operation of the tilting stand S. However, since it is more difficult to move or lift the leg portion Fk of the liquid crystal display L1 than the tilting stand S side such as the opening / closing operation, the rubber roller g is preferably located at the lower end of the tilting stand S. .

  In some cases, the screen has a large screen like a plasma display. However, in the present embodiment, when the one-way clutch 1 is applied to the opening / closing operation of the tilting stand S, the stopping torque works in the tilting direction in which the tilting angle of the partition member increases, and a force greater than the stopping torque is applied. Since the tilting stand is expanded by rotating the hinge part, there is no risk that the operator will unintentionally expand it beyond its allowable range. On the other hand, in the vertical direction in which the inclination angle of the partition member becomes small, the hinge member idles and the inclination stand closes by its own weight, so that the closing operation is easy. The rubber roller g assists this operation. If a roller g such as the tilting stand S is also attached to the leg Fk, the plasma display can be placed in a vertical posture and then transported while being pushed in a predetermined direction.
