BEST MODE FOR CARRYING OUT THE INVENTION
The best mode for carrying out the present invention will be described hereinafter with reference to the drawings.
FIGS. 1 and 2 show a first embodiment of the present invention. A display device A according to the first embodiment comprises a panel (base material) 1 and an engagement member 2.
The panel 1 is formed in a flat plate by an aluminum die material. Of course, the panel 1 may be formed of other plate material such as, for example, a plate material or a hollow plate material made of synthetic resin such as polyethylene, or a cosmetic plate made of wood. The panel 1 is vertically arranged and its rear surface (right surface in FIG. 1) 1a is fixed to a vertical wall surface (not shown). A plurality of engagement parts 1c extending horizontally in a left and right direction are formed on a vertical front surface 1b of the panel 1. The respective engagement parts 1c are arranged at constant intervals in a vertical direction. A tip part of each engagement part 1c is bent downwardly in a generally semi-circular configuration. Thus, an engagement recess 1d is defined by the front surface 1b of the panel 1 and the engagement part 1c. A lower end of this engagement recess 1d on the panel 1 side is externally downwardly opened.
The engagement member 2 includes a main body part 3, a first engagement part (engagement part) 4 and a second engagement part 5. The main body part 3 is formed in a flat plate-like configuration from aluminum, synthetic resin, wood or the like. The left and right length and the vertical length of the main body part 3 are properly determined depending on for what purpose the engagement member 2 is to be used. The main body part 3 is provided at a front surface 3a thereof with a support member 6. This support member 6 is formed in a suitable configuration depending on for what purpose it is to be used. For example, in case a hunger (not shown) is hang on the support member 6 or the support member 6 supports one end of a horizontal rack board, the support part 6 is formed in a rod-like configuration. In case the support member 6 itself is a rack board, it is formed as a flat plate extending in the left and right direction. Although the support member 6 is formed in the front surface 3a of the main body part 3 in the embodiments to be described hereinafter, it is not shown in any drawing for those embodiments excepting the present embodiment.
The first engagement part 4 is formed on an upper end of a rear surface 3b of the main body part 3 in such a manner as to protrude toward the panel 1. The left and right length of the first engagement member 4 is set equal to the left and right length of the main body 3. But the former may be set shorter than the latter. In case the left and right length of the first engagement member 4 is set shorter than that of the main body 3, it is also accepted that a plurality of first engagement parts 4 are formed and they are mutually spacedly arranged in the left and right direction. As shown in FIG. 1, the height (protruding amount from the main body part 3 toward the panel 1) of the first engagement member 4 is determined such that when the engagement member 2 is attached to the panel 1 with the main body part 3 kept generally parallel to the panel 1 (the position occupied by the engagement member 2 at that time shall be hereinafter referred to as the attaching position), a tip surface of the first engagement part 4 is almost contacted with the front surface 1b of the panel 1.
An engagement claw part 4a, which protrudes upwardly from the first engagement part 4 and whose tip end is bent at an approximately right angle in a direction away from the panel 1, is formed on the panel 1 side end of the upper surface of the first engagement part 4. This engagement claw 4a can be inserted into the engagement recess Id through its open part in the following manner. First, the main body part 3 is inclined upwardly to the right in FIG. 1 at a proper angle so that a lower end of the main body part 3 is more separated from the panel 1 than the upper end. Then, while maintaining the inclined state, the entire engagement member 4 is translated upwardly along the panel 1. By doing so, the engagement claw part 4a can be inserted into the engagement recess 1d through its open part at its end (the position occupied by the engagement member 2 at that time shall be hereinafter referred to as the removing position). In the removing position, the main body part 3 is turnable about the open part of the engagement recess 1d so that the lower end of the main body part 3 is brought toward the panel 1. When the main body part 3 is turned until the tip surface of the first engagement part 4 is brought nearly into contact with the front surface 1b of the panel 1, the engagement member 1 reaches the attaching position. When the engagement member 1 reaches the attaching position, the tip part of the engagement claw part 4a is brought into engagement with the tip part of the engagement part 1c facing the engagement recess 1d. By engagement between the engagement claw part 4a and the engagement part 1c, the upper end of the engagement member 2 is prohibited from moving forwardly and downwardly. Backward movement of the engagement member 2 is prohibited by abutment of the first engagement part 4 with the front surface 1b of the panel 1. By turning the engagement member 2 from the attaching position to the removing position, engagement of the engagement claw part 4a with the engagement part 1c can be released. Thereafter, the engagement claw part 4a can be removed from the engagement recess 1d by translating the engagement member 2 downwardly from the removing position.
The second engagement part 5 is formed on a lower end of the rear surface 3b of the main body part 3 in such a manner as to protrude toward the panel 1. The left and right length of the second engagement part 5 may be equal to or shorter than the left and right length of the main body part 3 as in the case with the first engagement part 4. Of course, in case the left and right length of the second engagement part 5 is shorter than the left and right length of the main body part 3, a plurality of second engagement parts 5 may be mutually spacedly arranged in the left and right directions. The height of the second engagement part 5 is set equal to the height of the first engagement part 4.
An engagement recess 5a is formed in a tip surface (surface opposing the panel 1) of the second engagement part 5. The configuration of the engagement recess 5a is determined such that when the engagement member 2 is located at the attaching position, the entire engagement part 1c (this engagement part 1c is adjacent to the lower side of the engagement part 1c with which the engagement claw part 4a of the first engagement part 4 is engaged) is fitted into the engagement recess 5a. The end part of the engagement recess 5a on the open side (panel 1 side) is opened downwardly.
A lower side end of the second engagement part 5 is thin because the engagement recess 5a is arranged below the center of the second engagement part 5 in the vertical direction, and the lower end is provided as an elastic element part (connection means) 5b. This elastic element part 5b is formed in an arcuate configuration generally along the outer surface of a tip part (lower end) of the engagement part 1c. A groove part 5c is formed in the surface of a basal end of the elastic element part 5b opposing the engagement part 1c. Formation of the groove part 5c makes it possible for the elastic element part 5b to be elastically deformed so that its distal end is turned and displaced in the direction (vertical direction in this embodiment) toward and away from the engagement part 1c. A protrusion part 5d protruding upwardly toward the inside of the engagement recess 1d is formed on the distal end of the elastic element part 5b. This protrusion part 5d, when the engagement member 2 is located at the attaching position, is engaged with the engagement part 1c by elastic force of the elastic element part 5b. That is, the side part of the protrusion part 5d on the reverse side of the panel 1 is pressure-contacted with the tip surface 1e of the engagement part 1c opposing the panel 1 by elastic force of the elastic element part 5b. 
When the engagement member 2 is located at the attaching position, forward movement (movement in the direction away from the panel 1) of the upper end of the engagement member 2 is prohibited by engagement between the engagement part 1c and the first engagement part 4 and forward movement of the lower end of the engagement member 2 is prohibited by engagement between the engagement part 1c and the second engagement part 5 (engagement between the engagement part 1c and the protrusion part 5d of the elastic element part 5b), thereby forward movement of the engagement member 2 is prohibited. Vertical movement of the engagement member 2 is prohibited by holding the engagement part 1c between the protrusion part 5d and the side surface on the upper side of the engagement recess 5a and/or holding the two engagement parts 1c, 1c between the protrusion part 5d and the engagement claw part 4a of the first engagement part 4. Furthermore, movement of the engagement member 2 in the left and right direction is prohibited by frictional resistance between the engagement part 1c and the protrusion part 5d and between the engagement part 1c and the side surface of the engagement recess 5a, and/or between the engagement part 1c and the protrusion part 5d and between the engagement part 1c and the engagement claw part 4a. The engagement member 2 is attached to the panel 1 at the attaching position as in the manner mentioned above.
Although the protrusion part 5d is engaged with the tip part of the engagement part 1c by elasticity of the elastic element part 5b, engagement of the protrusion part 5d with the engagement part 1c can be released by applying force having a magnitude larger than a predetermined magnitude to the lower end of the engagement member 2 forwardly. That is, since the tip surface 1e of the engagement part 1c is inclined toward the panel 1 as it goes upwardly, the protrusion part 5d is pushed downwardly by the tip surface 1e when force having a magnetude larger than a predetermined magnitude is applied to the lower end of the engagement member 2 forwardly. In case this pushing force is larger than the elastic force of the elastic element part 5b, the protrusion part 5d is slid on the tip surface 1e downwardly. When the protrusion part 5d is escaped downwardly from the tip surface 1e, engagement between the protrusion part 5d and the tip surface 1e is released. That is, engagement between the second engagement part 5 and the engagement part 1c is released. As a result, the lower end of the engagement member 2 becomes movable forwardly.
A control part 3c projecting downwardly from a lower end surface of the main body part 3 is formed on the main body part 3. This control part 3c is used at the time of moving the lower end of the main body part 3 forwardly and the length of the control part 3c is set such that the control part 3c can be pulled forwardly by hooking a finger thereon. Particularly, in this embodiment, the length of the control part 3c is set such that a tip part (lower end) of the control part 3c is located below a position where the protrusion part 5d and the engagement part 1c is engaged, i.e., a position where the protrusion part 5d and the tip surface 1e are contacted with each other.
In order to attach the engagement member 2 to the panel 1 in the display device A thus constructed, the engagement member 2 is brought to a posture which the engagement member 2 takes in the removing position and the engagement claw part 4a is brought into an opposing relation to the open part of the engagement recess 1d. Then, the engagement member 2 is translated upwardly to the removing position and tip part of the engagement claw part 4a is inserted into the engagement recess 1d. Thereafter, the engagement member 2 is moved from the removing position to the attaching position. By doing so, the first engagement part 4 is engaged with the engagement part 1c. During the process for turning the engagement member 2 from the removing position to the attaching position, the protrusion part 5d is abutted with an outer surface on the lower side of the engagement part 1c as shown in FIG. 2. When the engagement member 2 is further turned toward the attaching position in that state, the protrusion part 5d is moved downwardly against elasticity of the elastic element part 5b by the outer surface of the engagement part 1c. The protrusion part 5d passes over the outer surface of the engagement part 1c immediately before the engagement member 2 reaches the attaching position. Then, the protrusion part 5d is moved upwardly by elasticity of the elastic element part 5b and abutted with the tip surface 1e of the engagement part 1c. By doing so, the second engagement part 5 is engaged with the engagement part 1c. When the first and second engagement parts 4, 5 are engaged with the engagement parts 1c, 1c respectively, the engagement member 2 is attached to the panel 1.
In order to remove the engagement member 2 from the panel 1, first, the lower end of the engagement member 2 is moved forwardly. At that time, by hooking a finger on the control part 3c, the lower end of the engagement member 2 can easily be moved forwardly. Moreover, in this embodiment, since the tip part of the control part 3c is located forward of the contacting position between the protrusion 5d and the tip surface 1e of the engagement part 1c in the direction toward the second engagement part 5 from the first engagement part 4, the lower end of the engagement member 2 can more easily be moved forwardly. That is, to move the lower end of the engagement member 2 forwardly means that the second engagement part 5 is turned clockwise, in FIG. 1, generally about the first engagement part 4, serving the first engagement part 4 as a fulcrum, the contacting position between the protrusion part 5d and the tip surface 1e as an acting point and the control part 3c as a force point. Therefore, presuming that the control part 3c is formed between the first engagement part 4 and the second engagement part 5, it is necessary to act a large force on the control part 3c in order to separate the protrusion part 5d from the tip surface 1e. Thus, it becomes difficult to move the lower end of the engagement member 2 forwardly. In this respect, since the length of the control part 3c is set such that the tip part of the control part 3c is located below the contacting position between the protrusion part 5d and the tip surface 1e of the engagement part 1c in this embodiment, the protrusion part 5d can be separated from the tip surface 1e by acting only a small force on the control part 3c. Accordingly, the lower end of the engagement member 2 can easily be moved forwardly against elasticity of the elastic element part 5b. 
After the lower end of the engagement member 2 is moved forwardly until the engagement member 2 reaches the removing position, the engagement member 2 is translated downwardly and the engagement claw part 4a is removed from the engagement recess 1d. By doing so, the engagement member 2 can be removed from the panel 1. Since the second engagement part 5 is separated forwardly from the engagement part 1c when the engagement member 2 is located at the removing position, the second engagement part 2 is not brought into abutment with the engagement part 1c when the engagement member 2 is moved downwardly.
Other embodiments of the present invention will be described next. In the embodiments to be described hereinafter, only those components different from those of the first embodiment are described, and those components identical with those of the first embodiment are denoted by identical reference numerals and description thereof is omitted.
FIG. 3 shows a second embodiment of the present invention. In a display device B of the second embodiment, the vertical space of the engagement part 1c is smaller than that of the first embodiment, and the space between the two engagement parts 1c, 1c is set such that the two engagement parts 1c, 1c are inserted between the first engagement part 4 and the second engagement part 5. A lock member 7 is removably attached to at least one of the left and right sides of the engagement member 2. The lock member 7, when attached to the engagement member 2, is movable in a removing direction with respect to the engagement member 2 but it is non-movable in any other direction with respect to the engagement member 2. The lock member 7, as shown in FIG. 4, is in the shape of a flat plate and provided at its surface opposing the engagement member 2 with a plurality of projections 7a. The respective projections 7a are arranged in such a manner as to be abutted with the tip surface of the engagement part 1c when the lock member 7 is attached to the engagement member 2. Accordingly, in this display device B, the engagement member 2 is non-removable from the panel 1 unless the lock member 7 is removed from the engagement member 2.
FIG. 5 shows a third embodiment of the present invention. In a display device C of the third embodiment, a lower end of the main body part 3 facing nearly a half of the lower side of the engagement recess 5a is in the shape of a thin plate. This plate-shaped part serves as the elastic element part 5b. Accordingly, the elastic element part 5b of the third embodiment is longer than the elastic element part 5b of the first embodiment shown in FIGS. 1 and 2. As a result, the elastic element part 5b has elasticity although it has no groove part 5c. A nearly semi-circular bent part 5e, instead of the protrusion part 5d, is formed on the distal end of the elastic element part 5b. This bent-part 5e is abutted with the tip surface 1e by elasticity of the elastic element part 5b. The vertical width of the engagement recess 5a is larger than the vertical width of the engagement part 1c, so that an inner surface of an upper half part of the engagement recess 5a is separated from the engagement part 1c when the engagement member 2 is located at the attaching position. Accordingly, in the display device C of the third embodiment, the engagement claw part 4a and the elastic element part 5b sandwichingly hold the two engagement parts 1c, 1c. The control part 3c is branched from the basal end of the elastic element part 5b and allowed to extend downwardly. That is, the control part 3c and the elastic element part 5b commonly include a basal end.
FIG. 6 shows a fourth embodiment of the present invention. In a display device D of the fourth embodiment is a modification of the display device C shown in FIG. 5. In this display device D, the control part 3c is integrally formed with an intermediate part of the elastic element part 5b and allowed to extend downwardly from the intermediate part of the elastic element part 5b. 
FIG. 7 shows a fifth embodiment of the present invention. In a display device E of the fifth embodiment is a modification of the display device C shown in FIG. 5. In this display device E, the control part 3c is integrally formed with a tip part of the bent-part 5e and allowed to extend downwardly from the tip part of the bent-part 5e. 
FIG. 8 shows a sixth embodiment of the present invention. A display device F of the sixth embodiment is a modification of the display device B shown in FIG. 3. This display device F is different from the display device B in the respects that it includes no engagement member 7 and that a connection mechanism 8 is provided instead of the second engagement part 5.
The connection mechanism 8 includes a turning member (displacing member) 81. An intermediate part of this turning member 81 is turnably connected to the lower end of the main body part 3 through a shaft 82 extending horizontally in the left and right direction. The turning member 81 is turnable between an engaging position shown in FIG. 8(A) and a releasing position shown in FIG. 8(B). The turning member 81 is turn biased in a direction toward the engaging position from the releasing position by a spring (biasing means) 83. When the turning member 81 is located in the engaging position, an abutment surface 81a formed on a lower end of the turning member 81 is pressure-contacted with the tip surface 1e of the engagement part 1c by biasing force of the spring 83. That is, the turning member 81 is engaged with the engagement part 1c by the spring 83. When the turning member 81 is in engagement with the engagement part 1c, the engagement claw part 4a of the first engagement part 4 and the turning member 81 sandwichingly hold the two engagement parts 1c, 1c. 
A control part 81b extending upwardly is disposed at an upper end of the turning member 81. When this control part 81b is pushed toward the panel 1, the turning member 81 is turned toward the releasing position from the engaging position against biasing force of the spring 83. When the turning member 81 is located at the releasing position, the abutment surface 81a is separated from the tip surface 1e of the engagement part 1c and engagement between the turning member 81 and the engagement part 1c is released.
In order to attach the engagement member 2 including the main body part 3, the first engagement part 4 and the connection mechanism 8 to the panel 1 in the display device F thus constructed, first, the engagement member 2 is brought to the removing position in the same manner as in the above embodiments. At this time, the turning member 81 is turn biased toward the engaging position from the releasing position by the spring 83 and the upper end of the turning member 81 comes into abutment with the lower end of the main body part 3 thereby the turning member 81 is stopped at the same position as the engaging position or at a position slightly beyond the engaging position. When the main body part 3 is turned toward the attaching position from the removing position, the lower end of the turning member 81 is brought into abutment with the outer surface of the engagement part 1c during the turning of the main body part 3. Thereafter, when the engagement member 2 is further turned toward the attaching position, the turning member 81 is turned toward the releasing position from the engaging position by the outer surface of the engagement part 1c against biasing force of the spring 83. When the engagement member 2 reaches the attaching position, the turning member 81 is turned to the engaging position by the spring 81 and the abutment surface 81a is pressure-contacted with the tip surface 1e. As a result, the engagement member 2 is attached to the panel 1.
With the engagement member 2 attached to the panel 1, when the control part 81b is pushed toward the panel 1, the turning member 81 is turned toward the releasing position from the engaging position against biasing force of the spring 83 and engagement between the turning member 81 and the engagement part 1c is released. As a result, the engagement member 2 becomes turnable from the attaching position to the removing position. Thereafter, the engagement member 2 can be removed from the panel 1 in the same manner as in the above embodiments.
FIG. 9 shows a seventh embodiment of the present invention. A display device F′ of the seventh embodiment is a modification of the display device F, and it employs a turning member 81′ instead of the turning member 81 of the connection mechanism 8. In this turning member 81′, a control part 81c extending downwardly is formed on its lower end. The vertical length of the control part 81′ is longer than the distance from a contacting position between the abutment surface 81a and the tip surface 1e to the center of the shaft 82. Owing to this arrangement, the turning member 81′ can easily be turned and the engagement member 2 can easily be removed from the panel 1. Other construction is same as that of the display device F.
FIG. 10 shows an eighth embodiment of the present invention. A display device G of the eighth embodiment is a modification of the display device F, and it employs a connection mechanism 9 instead of the connection mechanism 8 of the display device F. The connection mechanism 9 includes a movable member (displacing member) 91. This movable member 91 is disposed at the lower end of the main body part 3 in such a manner as to be movable between an engaging position shown in FIG. 10(A) and a releasing position shown in FIG. 10(B). The movable member 91 is biased toward the engaging position from the releasing position by a spring (biasing means) 92. When the movable member 91 is located at the engaging position, an abutment surface 91a formed on the movable member 91 is pressure-contacted with the tip surface 1e of the engagement part 1c by biasing force of the spring 92. That is, the movable member 91 is in engagement with the engagement part 1c. When the movable member 91 is engaged with the engagement part 1c, the movable member 91 and the engagement claw part 4a of the first engagement part 4 sandwichingly hold the two engagement parts 1c, 1c. When the movable member 91 located at the engaging position is moved toward the releasing position (downwardly) against biasing force of the spring 92, the abutment surface 91a is separated from the tip surface 1e downwardly. As a result, the engagement member 2 becomes turnable from the attaching position to the removing position. A protrusion part 91b protruding forwardly is formed on a lower end of the movable member 91. By pushing this control part 91b downwardly by finger, the movable member 91 can be moved from the engaging position to the releasing position against biasing force of the spring 92.
In order to attach the engagement member 2 including the main body part 3, the first engagement part 4 and the connection mechanism 9 to the panel 1 in the display device G thus constructed, the engagement member 2 is brought into the removing position in the same manner as in the above embodiments. At that time, the movable member 91 is biased toward the engaging position from the releasing position by the spring 92 and it is located in the engaging position or in a position slightly beyond the engaging position due to its abutment with the lower end of the main body part 3. When the engagement member 2 is turned from the removing position to the attaching position, the movable member 91 is abutted with the outer surface of the engagement part 1c in mid-course of turning. By this, the movable member 91 is moved toward the releasing position from the engaging position in accordance with turning of the engagement member 2. When the engagement member 2 reaches the attaching position, the movable member 91 is moved to the engaging position by the spring 92 and the abutment surface 91a is pressure-contacted with the tip surface 1e. By doing so, the engagement member 2 is attached to the panel 1. When the abutment surface 91a is separated from the tip surface 1e downwardly by moving the movable member 91 from the engaging position to the releasing position, the engagement member 2 becomes turnable toward the removing position from the attaching position. Thus, the engagement member 2 can be removed from the panel 1.
FIG. 11 shows a ninth embodiment of the present invention. In a display device H of the ninth embodiment, the engagement member 2 includes a connection mechanism 10 instead of the connection mechanisms 8, 9. The connection mechanism 10 chiefly comprises a first connection member 101, a second connection member 102 and a spring (turn biasing means) 103.
The first connection member 101 is in a shape obtained by extending the lower end of the engagement claw part 4a downwardly by a predetermined length. Accordingly, an upper end of the first connection member 101 can be brought into engagement with the engagement part 1c in the same manner as with the engagement claw part 4a. With the first connection member 101 engaged with the engagement part 1c, the lower end of the first connection member 101 is connected to the panel 1 in such a manner as almost non-movable at least in the back and forth direction and downwardly.
The second connection member 102 is turnably connected at one end thereof to the lower end of the first connection member 101 through a shaft 104 horizontally extending in the left and right direction. The second connection member 102 is turnable between an engaging position shown in FIG. 11(A) and a releasing position shown in FIG. 11(B). The second connection member 102 is turn biased toward the engaging position from the releasing position by the spring 103. A control part 102a protruding downwardly is formed on the lower end of the second connection member 102. When this control part 102a is pushed toward the panel 1, the second connection member 102 is turned toward the releasing position from the engaging position against biasing force of the spring 103.
When the second connection member 102 is brought to the engaging position, an abutment surface 102b formed on an intermediate part of the second connection member 102 comes into abutment with the abutment surface 3d formed on the lower end of the main body part 3 and the lower end of the main body part 3 is pushed against the first connection member 101 by biasing force of the spring 103. As a result, the lower end of the main body part 3 is brought into engagement with the engagement part 1c through the first connection member 101 and connected to the panel 1 in such a manner as almost non-movable at least in the back and forth direction and downwardly. When the second connection member 102 is turned from the engaging position to the releasing position by pushing the control part 102a toward the panel 1, the abutment surface 102b is separated from the abutment surface 3d of the main body part 3, so that the lower end of the main body part 3 becomes movable forwardly and the main body part 3 becomes turnable from the attaching position to the removing position. The attaching position and the removing position of the main body part 3 are same as the corresponding positions of the main body part 3 of the engagement member 2 when the engagement member 2 is brought into the attaching positions and the removing positions in the above embodiments.
In order to attach the engagement member 2 to the panel 1 in the display device H thus constructed, the main body part 3 is brought into the removing position and the first connection member 101 is brought into engagement with the engagement part 1c. At that time, the second connection member 102 is biased toward the engaging position from the releasing position by the spring 103 and it is located at the engaging position or a position slightly beyond the engaging position by a stopper mechanism (not shown) disposed between the first connection member 101 and the second connection member 102. When the main body part 3 is turned toward the attaching position from the removing position, an inclination surface 3e formed on the lower end surface of the main body part 3 is abutted with the second connection member 102 during the turning of the main body part 3 and the second connection member 102 is turned toward the releasing position. When the main body part 3 is turned to the attaching position, the lower end of the main body part 3 is brought into abutment with the first connection member 101 and the second connection member 102 is turned from the releasing position to the engaging position by the spring so that its abutment surface 102b is abutted with the abutment surface 3d of the main body part 3 to push the lower end of the main body part 3 against the first connection member 101. By doing so, the engagement member 2 is attached to the panel 1.
In order to remove the engagement member 2 from the panel 1, the control part 102a is pushed toward the panel 1 and the second connection member 102 is turned from the engaging position to the releasing position. Thereafter, the main body part 3 is turned from the attaching position to the removing position. Then, the main body part 3 is moved downwardly to remove the panel 1. By doing so, the entire engagement member 2 is removed from the panel 1.
The present invention should not be limited to the above embodiments but many changes and modifications, if necessary, can be made without departing from the gist of the invention.
For example, in the above embodiments, the tip part of the engagement part 1c is formed in such a manner as to be bent downwardly in the shape of a semi-circle. However, it is also accepted that the tip part of the engagement part 1c is bent upwardly in the shape of a semi-circle. In that case, by using the engagement member 2 in an upside down posture, the engagement member 2 can be removably attached to the panel 1.
INDUSTRIAL APPLICABILITY
The engagement member according to the present invention can be used in a display device for displaying clothes and the like.
