Description

  The present invention relates to a door stop device that locks or holds a door in an open state.

  There is a problem that when the door of a door such as a room is greatly opened, the door tip portion and the lever handle lock collide with the wall surface and are damaged. In order to prevent this problem, a door stopper has been conventionally used. These door stoppers are usually configured such that a base material having a cushioning member such as rubber disposed at the tip is taken out and attached from the floor or wall surface, and the door surface hits the buffer member to stop the door from opening. Also, if the door is left open, it is necessary to prevent it from closing with a large impact by a strong wind. Also, when the vehicle is passed many times by a cart, etc., it is held in the open position. Therefore, there is also a locking means that can hold the door in its position by providing hook-type metal fittings and engaging tools for the door and the base material, and engaging each other with the door open. Many are provided.

  However, the door stoppers as described above are inevitably placed in a state where the base material protrudes greatly from the floor or wall surface, which interferes with cleaning and is not good in design. It has been judged that it is non-conforming in recent years when emphasizing barrier-free.

  Also, when trying to lock the door in the open state, hold the hook with a small hook-shaped metal fitting that moves randomly while bending over the upper body, and insert or remove the tip of the hook into the engagement tool. And the release operation must be performed, which is considered extremely difficult for the elderly and disabled.

  As a result, a structure in which a stopper device formed thinly on the floor surface is provided and a main body device composed of a case member having a locking portion and a magnet is attached to the lower part of the door side of the door is disclosed in JP-A-10-115139 and Japanese Patent No. 2983530. And Japanese Patent No. 2990601. The stopper device with the above structure consists of a metal-made flap that is attracted to the magnet and a base seat, and the flap is mounted on the base seat so that it can rotate in the vertical direction, and normally it does not protrude as much as possible from the floor surface. Has been made. In other words, the basic operation of this configuration is that when the door is opened and the main body device approaches the stopper device, the flap is attracted and lifted by the magnet, and the front end of the flap comes into contact with the locking portion of the case member to open the door. It is configured to lock.

  However, in the above configuration, the door opening position is held only by the attractive force of the magnet and the flap, and the configuration in which the door is closed does not include any restriction, so it is easily closed by wind or the like. The problem remains that it cannot be held securely with the door open.

  In view of this, the present inventor reported in Japanese Patent Laid-Open No. 2002-47851 a configuration that can be reliably held in a state in which the door is opened and that has excellent operability for holding and releasing. In this configuration, first, a lock member having an operation portion is incorporated in the main body device in an interlocked manner, and an engagement portion is provided on the flap of the stopper device. Then, with the flap lifted by magnetic force and brought into contact with the locking portion of the main unit, that is, with the door locked in the opening direction, the lock member is engaged with the engaging portion of the flap by the operating means, and the door is closed. The movement in the direction is also restricted.

  Also, in the above configuration, the main body device approaches the stopper device as the door is opened, the flap is attracted to the magnet and lifted and locked together, the strength of the magnetic force of the a magnet, the distance between the b flap and the magnet, c The weight of the flap and d the opening speed of the door are the main factors. The larger the magnet's attractive force, the better the distance between the flap and the magnet, the shorter the flap itself, and the lighter the flap itself, the better the door. The slower the opening speed, the better the conditions for locking.

  In other words, in the door stopper device in which the base material provided with the buffer member at the tip is taken out and attached from the floor or wall surface, it is absolutely necessary for any condition as long as the base material protrudes in the rotation range of the door surface. In contrast, the opening of the door can be restricted at a predetermined position, whereas in the configuration using the above magnetic force, the opening of the door can be restricted only under a condition within a certain range. Therefore, when the above condition is extremely deviated, a swinging phenomenon occurs in which the main body device mounted on the door passes through the stopper device position without being locked, and the function as the door stopper device cannot be performed. Accordingly, the present condition range is set to be finite and is used so that a reliable closing operation can be obtained only within the range.

However, in recent years, there are many doors that have a considerably large gap in the distance between the lower end surface of the door and the floor surface due to ventilation problems and the like. Also, the magnetic force is relatively proportional to the volume of the magnet, but when the main unit is attached to the door surface, design is important to completely expose it, and it is necessary to make the overall size compact, Both are contradictory factors.
JP-A-10-115139 Patent 2983530 Patent No. 2990601 JP 2002-47851 A

  The present invention has been made to solve the above-mentioned problems, can cope with a wide range of gaps between the lower end surface of the door and the floor, can be manufactured in a relatively compact size, and is excellent in design. Furthermore, it aims at providing the door stopper which can be hold | maintained and cancellation | release in an open state, and was excellent also in the operativity.

  First, a main body case, a magnet, a moving body, and an elevating member are provided, and the magnet and the elevating member are arranged so as to be movable in the vertical direction within the main body case. Then, the moving body is similarly disposed in the main body case in the state of being close to the elevating member to constitute the main body device. At this time, the elevating member and the magnet are arranged so as to be movable in the vertical direction with respect to the door. And an inclined surface and a latching | locking part are formed in the raising / lowering member, a moving body is arrange | positioned so that an inclined surface may be touched, and a main body apparatus is comprised. The moving body is set so that it can move in the left-right direction parallel to the door surface in the main body case, and the inclined surface of the elevating member is pushed in conjunction with the operation of the moving body, so that the elevating member moves up and down. Try to move in the direction.

  The stopper device is made of a metal flap and a base seat which are attracted by a magnet, and the flap is mounted on the base seat so as to be rotatable in the vertical direction. Normally, the entire surface is thinned while the flap surface and the base seat surface are in close contact with each other due to the weight of the flap. Then, the stopper device is fixed to the floor, and the main body device is fixed to the lower part of the door. As a basic operation of both, when the door is opened and the main body device approaches the stopper device, the flap is attracted and lifted by the magnet, and the opening of the door is regulated by the front end of the flap coming into contact with the engaging portion of the elevating member. be able to.

  Here, in order to obtain an operation in which the moving body moves in the left-right direction, it is preferable to use a centrifugal force generated by an opening / closing operation of the door. That is, the moving body moves in the main body case in the direction of the door end by centrifugal force due to the sudden opening operation of the door, and the lifting member and the magnet position can be moved downward in conjunction with the operation. Accordingly, the moving body itself is set as a spherical body or a cylindrical rolling element having a predetermined weight, the rolling body is inserted in a state of riding on a horizontal surface in the main body case, and a plurality of inclined surfaces are provided on the elevating member. It is good to arrange | position adjacent to a rolling element in the state which protruded above the horizontal surface. Then, the rolling element moves in the main body case while pushing down the inclined surface of the elevating member by the centrifugal force generated by the opening operation of the door, and the magnet and the engaging portion can be moved downward together with the elevating member.

  Therefore, the moving body is preferably set with a material having a large specific gravity so as to obtain a stronger centrifugal force per volume. Moreover, it is good to comprise so that a raising / lowering member containing a magnet may be hold | maintained in the predetermined position in the state which floated substantially with respect to the main body case so that a raising / lowering member can be operated even with smaller centrifugal force. As a means for this, it is preferable to insert a spring member between the main body case and the lifting member so as to suspend the weight of the lifting member and the magnet or to have a strength that the lifting member and the magnet barely move downward.

  As another configuration for moving the moving body in the left-right direction in the main body case by centrifugal force, similarly, the moving body is set with a material having a high specific gravity, and a sphere or cylinder is separately provided between the moving body and the horizontal plane in the case. A configuration is also suitable in which a rolling element such as a roller having a shape is arranged and inserted with the moving body on the rolling element to obtain a stronger centrifugal force at a constant door closing speed. This configuration differs from the above configuration in that the rolling element does not play the role of the moving body itself, and is characterized in that the shape and weight of the moving body can be set relatively arbitrarily.

  When the main body device and the stopper device configured as described above are mounted separately on the door and the floor, and the door is closed at a predetermined speed or more, the moving body moves in the direction of the door due to the centrifugal force and is locked together with the lifting member. The position of the magnet and the position of the magnet move downward, and the distance between the magnet and the flap becomes shorter, so that the flap can be attracted with a stronger magnetic force. A more reliable locking operation of the door can be obtained by contact.

  Further, as an element for lifting another flap by a magnetic force, it is mentioned that the lighter weight of the flap is better. However, if the angle at which the flap is lifted when the door is locked is too large, the flap rises when the flap tip comes into contact with the locking portion. Therefore, it is necessary to set the flap lifting angle to a predetermined angle or less. is there. Then, when the clearance between the floor surface and the lower end of the door is large, it is necessary to make the flap itself into a long shape, and the strength of the flap itself is also required, which tends to be relatively heavy.

  Therefore, a spring member is installed between the base seat of the stopper device and the flap, and it is suspended with the weight of the flap itself or urged in the direction of lifting so that the flap is barely lifted, and the magnet of the main unit approaches. In such a case, a configuration in which the flap is sucked and lifted easily is effective.

  In addition, a lock mechanism that can be securely held with the door opened and that can be released with a simple operation is also required. As its configuration, a lock member having an engagement portion and an operation portion is further incorporated in the main body device, and an engagement hole is provided in the flap of the stopper device. Then, when the flap is lifted by the magnetic force and comes into contact with the locking portion of the main unit, that is, the door is restricted in the opening direction, the engagement portion is engaged with the engagement hole of the flap by the operating means. Movement in the direction can be restricted. In addition, the door can be closed as it is by releasing the engaged state between them by a simple operation.

  The elevating member having the magnet and the locking portion can be lowered downward in conjunction with the movement of the moving body utilizing centrifugal force, and the distance between the magnet and the flap is shortened to attract the flap with a stronger magnetic force. As a result, a more reliable locking operation of the door can be obtained by contact between the locking portion provided on the elevating member and the flap tip.

  In the door stopper device using the magnet and the flap of the conventional configuration, the locking condition in which the locking portion and the flap tip come into contact with each other in a substantially inverse proportion to the increase in the moving opening / closing speed of the door is deteriorated. The centrifugal force is very effective because it increases substantially in proportion to the moving speed of the door.

  Because the elevating member and the moving body move only a certain distance within the main body case, the main body device itself can be set in a relatively compact shape, and can be used for both door imposition and digging. It can be easily implemented with a configuration that also serves as a hand. Moreover, it can be configured with a relatively small number of parts, and can be easily produced at low cost.

  Install a spring member between the base seat and the flap of the stopper device and suspend it with the weight of the flap itself or urge it in the direction of lifting so that the flap does not lift up. In this case, it is possible to obtain a configuration in which the flap is sucked and lifted easily.

  A lock member consisting of an engagement part and an operation part is further incorporated in the main unit, and the flap of the stopper device is provided with an engagement hole, so that the flap is lifted by a magnetic force and comes into contact with the locking part of the main unit. With the door regulated in the opening direction, the locking means engages the engaging part of the flap with the engagement hole of the flap to restrict the movement of the door in the closing direction, and the release means closes the door as it is. Can do.

  Embodiments of a door stopper according to the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of the main body device a of the present invention, and the mounting holes 7 and details on the door surface are omitted for easy understanding. FIG. 2 is a perspective view of the stopper device b according to the present invention. The stopper device b is composed of a flap 12 having an engagement hole 14 and a base seat 13, and the flap 12 rotates in the vertical direction with respect to the base seat 13. It is installed as possible. FIG. 2 shows a state in which the flap 12 is lifted up. In the normal state, the flap 12 is lowered by its own weight, and the entire stopper device b that is in close contact with the base seat 13 is thin.

  As shown in FIG. 1, the main body device a includes a main body case 1, a moving body 2, an elevating member 3, a back cover 4, and a magnet 5, and the magnet 5 is incorporated in the elevating member 3. FIG. 3 is a plan view of the main body case 1, and FIG. 4 is a top view of the main body case 1. As shown in FIGS. 3 and 4, the main body case 1 is substantially box-shaped and has a space inside. A cross-shaped horizontal surface 6 is provided at an intermediate position in the vertical direction, and a mounting hole 7 and a bottom surface 8 are provided.

  FIG. 5 is a front view of the elevating member 3, FIG. 6 is a top view of the elevating member 3, and FIG. 7 is a side view of the elevating member 3. As shown in FIG. 5, the elevating member 3 has an inverted C-shaped inclined surface 9 at the top, and a slit is provided in the thickness direction of the inclined surface 9 as shown in FIG. 7. And the magnet 5 is built in the lower position, and the latching | locking part 10 is provided in the lowest position.

  FIG. 8 shows a state in which the elevating member 3 incorporating the magnet 5 and the moving body 2 are arranged in the main body case 1. The elevating member 3 is inserted from below the horizontal surface 6 of the main body case 1, and the elevating member 3 is inclined. Both are arranged so that the surface 9 protrudes above the horizontal surface 6. And the raising / lowering member 3 is comprised so that a fixed distance can be moved only to the up-down direction within the main body case 1. FIG. Therefore, the bottom surface 8 of the main body case 1 is formed in a partially open shape, and is set so that the locking portion 10 protrudes downward from the opening when the elevating member 3 is lowered. Further, the moving body 2 is preferably a sphere as shown in FIG. 8 or a cylindrical shape, and is arranged in the main body case 1 in a state where it is placed at the center position of the horizontal plane 6. The reason why the both sides of the central portion of the elevating member 3 in FIG. 5 are largely stolen is to avoid the attachment hole 7 portion of the main body case 1 shown in FIG.

  Next, as shown in FIG. 8, the spring member 11 is inserted between the bottom surface 8 of the main body case 1 and the elevating member 3, and the inclined surface 9 of the elevating member 3 is held in a state of protruding upward from the horizontal surface 6 of the main body case 1. To do. The relationship between the strength of the spring member 11 at this time and the weight of the elevating member 3 including the magnet 5 is important, and the inclined surface 9 is set to barely protrude on the horizontal plane 6. That is, the elevating member 3 including the magnet 5 is urged by the spring member 11 in a state of being substantially lifted so as to support the dead weight. Therefore, the moving body 2 is normally disposed on the horizontal plane 6 at the center position between the two inclined surfaces 9 of the elevating member 3 shown in FIG. Then, in the state of FIG. 8, the main body device a is mounted at the lower position of the door surface on the door-end side.

  FIG. 9 is a front view showing the internal operation of the main body device a attached to the lower part of the door. When the door 23 is stopped, the moving body 2 is in the center of the horizontal plane 6 as shown in FIG. It arrange | positions between the both inclined surfaces 9 of the position, and the raising / lowering member 3 is maintaining the state which barely floated. When the door 23 is suddenly opened from the above state, a centrifugal force is applied to the moving body 2, and the moving body 2 tries to roll on the horizontal surface 6 in the direction of the door. As shown in FIG. The operation of pushing down the three inclined surfaces 9 is obtained. As a result, the magnet 5 and the locking portion 10 are lowered downward with respect to the main body case 1.

  FIG. 10 is a side view showing the operation when the main body device a and the stopper device b are actually arranged on the door 23 and the floor surface 24 and the door 23 is suddenly opened. FIG. 10A shows a state in which the main body device a has not yet approached the stopper device b, but has already been pushed by the moving body 2 by the opening operation of the door 23 and the elevating member 3 is lowered. FIG. 10B shows a state in which the stopper device b approaches the main body device a, the flap 12 is attracted to the magnet 5, and the tip of the flap 12 abuts on the locking portion 10 to lock the opening operation of the door 23. Is shown. When the door 23 stops, it naturally returns to a state where no centrifugal force is applied. Therefore, although it is a very weak force, the elevating member 3 including the magnet 5 is substantially lifted by the urging force of the spring member 11 as shown in FIG. Return and hold in that state.

  Here, in the distance characteristic between the magnet 5 and the flap 12, it is known that the attractive force is inversely proportional to the square of the distance between the two. It is known that the speed of the door 23 is approximately inversely proportional. In other words, in the magnet 5 having the same strength, it is important that the attractive force decreases as the distance from the flap 12 increases, and at the same time, as the opening speed of the door 23 increases, it becomes more difficult to attract. Therefore, in the conventional type in which the positions of the magnet 5 and the locking portion 10 are fixed, the flap 12 and the locking portion 10 are in contact with each other at a low speed when the distance between the magnet 5 and the flap 12 is constant. Even if the door 23 can be locked, the swinging phenomenon occurs in which the door 23 passes before the flap 12 is lifted when the speed of the door 23 is increased. This idling phenomenon occurs even at a low speed as the distance between the magnet 5 and the flap 12 increases.

  Therefore, it is sufficient if the magnetic force of the magnet 5 itself can be set strong. However, the magnet 5 having a relatively strong magnetic force per volume tends to be expensive, and the size of the magnet 5 is also somewhat large for design and the like. However, there is still nothing that can widely cope with the distance between the lower end surface of the door 23 and the floor surface 24 and the required opening speed as a door stop device in various housings of the door. Therefore, the distance between the lower end surface of the door 23 and the floor surface 24 within a certain range is set as a range up to a certain opening speed, and it is used as a product that can secure the door stop function within that range. Currently.

  However, the door stop device of the present invention is very effective because the position of the magnet 5 and the locking portion 10 can be lowered downward as the opening speed of the door 23 is fast and the locking conditions are poor. Furthermore, in the configuration of the present invention, the lowering of the magnet 5 and the locking portion 10 is caused by the moving distance of the moving body 2 in the main body case 1 in the direction of the door and the angle of the inclined surface 9 of the elevating member 3. Since the dimensions can be set arbitrarily, it is possible to cope with a wider range of door accommodation conditions. Further, in the above description, the engaging portion 10 is provided on the elevating member 3, and the magnet 5 is further incorporated and moved downward simultaneously. However, the magnet 5 is in a fixed position with respect to the main body case 1. It is also possible to adopt a configuration in which only the elevating member 3 provided with the locking portion 10 is lowered by centrifugal force, and the effect related to suction is lower than in the above embodiment, but the flap 12 is sucked by the conventional configuration. In the case where it is lifted up and swung away without being able to keep up with the last minute, it is also effective in a configuration in which only the locking portion 10 is lowered.

  Here, when the clearance between the floor surface 24 and the lower end surface of the door 23 is small, if the lowering distance of the elevating member 3 is made larger than the reference minimum clearance, the locking portion 10 may rub against the floor surface 24 in the middle of opening. Care must be taken in this regard as it is assumed. Further, in FIG. 8, the inclined surface 9 of the elevating member 3 is formed in an inverted U shape in order to make the main body device a to be used for both right and left. Furthermore, although it is easier to obtain centrifugal force when the moving body 2 is set with a substance having a large specific gravity, steel that is inexpensive and has a relatively large specific gravity is attracted to the magnet 5 and is not suitable for the present invention. A non-magnetic material such as stainless steel SUS304, copper or brass rolling elements may be used.

  In the above configuration, a spherical rolling element is used as the moving body 2, but it is a necessary condition that the elevating member 3 including the magnet 5 is lowered by the centrifugal force due to the opening of the door 23. It is possible to assume a wide range of configurations. As described above, the centrifugal force for operating the moving body 2 is such that a greater force is obtained as the weight of the moving body 2 increases. However, when a sphere is used, it is sufficient for the thickness dimension and the vertical dimension of the main body case 1. It is assumed that the weight is difficult to obtain. FIG. 11 is a schematic diagram showing another configuration in which the weight of the moving body 2 can be easily obtained. The elevating member 3 having the main body case 1 and the locking portion 10 and the magnet 5 are the same, and the spring member 11 is similarly arranged to hold the elevating member 3 in a substantially lifted state. Here, the movable body 2 is formed in a mountain shape with a weight member 15 added, and a separate roller 16 is arranged between the movable body 2 and the horizontal surface 6 of the main body case 1 so that the movable body 2 can easily move in the direction of the door. deep. FIG. 11A shows the arrangement of the moving body 2 when the door 23 is stopped. When the moving body 2 is subjected to a centrifugal force when it is opened, the moving member 2 moves in the direction of the door in a state of riding on the roller 16 to move the elevating member 3. The operation of lowering is obtained. In this configuration, since the weight of the weight member 15 can be set relatively arbitrarily, a large centrifugal force can be obtained, and further, a condition range for locking the flap 12 and the locking portion 10 can be set wide.

  FIG. 12 shows another alternative, and is a schematic showing a configuration in which the pendulum member 17 receives a centrifugal force, not a configuration using the rolling element in the embodiment or a rolling member such as the roller 16 in the above alternative. FIG. The structure in which the elevating member 3 having the inclined surface 9, the magnet 5, and the locking portion 10 is inserted in the main body case 1 in a state of being substantially floated by the spring member 11 is the same. As shown in FIG. 12, the pendulum member 17 has a fan-shaped head at the top, and the top is heavy in the weight balance. Although not shown in the figure, the weight member 15 may be further arranged on the head. The lower part has a rod shape, and the tip is in contact with the lowest part of the inclined surface 9 of the elevating member 3, and the shaft center 18 is configured so as to be rotatable in parallel with the door surface at the center position. FIG. 12 (a) shows a state in which the door 23 is stopped. When the door 23 is opened, the head with a much larger weight balance receives centrifugal force and rotates around the axis 18, and as shown in FIG. 12 (b). Further, the lower end of the bar-shaped member can push the inclined surface 9 to lower the elevating member 3.

  The configuration of FIG. 12 pushes the elevating member 3 down along the trajectory of the rotational movement of the pendulum member 17, so that a descent distance equivalent to the configuration in which the rolling body is used as the moving body and the type in which the moving body 2 is placed on the roller 16 is obtained. The angle of the inclined surface 9 needs to be quite tight. However, in this configuration, the horizontal plane 6 in the main body case 1 is not necessary, and the size in the horizontal direction in which the rolling elements and the like roll in the left-right direction may be relatively small. Therefore, it is assumed that the main body device a itself can be made compact. .

  Next, the lock mechanism in the state where the door 23 is opened, which is required together with the locking operation by the contact between the flap 12 and the locking portion 10 described above, will be described. FIGS. 13 to 15 show an example of a lock mechanism. First, as shown in FIG. 13, the lock member 19 is provided with an engaging portion 21 having a knob-shaped operation portion 20 at the upper portion and a concave portion 22 at the lower portion. Is provided. Then, as shown in FIG. 14, a lock member 19 is disposed on the front surface of the main body case 1, and is mounted on the main body case 1 in a state where it can move a certain distance only in the vertical direction. At this time, the lock member 19 is set so as to be held with a considerably strong force in the front-rear direction with respect to the main body case 1. The state where the lower end of the engaging portion 21 of the lock member 19 shown in FIG. 14 does not protrude downward from the bottom surface 8 of the main body case 1 is the release position. Further, as shown in FIG. 2, an engagement hole 14 is provided at a predetermined position of the flap 12.

  When the door 23 is opened from the above configuration, the flap 12 of the stopper device b is sucked into contact with the locking portion 10 of the main body device a, and the state shown in FIG. 15A after the door 23 is locked. become. At this time, the engagement portion 21 of the lock member 19 and the engagement hole 14 of the flap 12 are arranged in a straight line in the vertical direction. When the lock member 19 is lowered by pushing the operating portion 20 from the state shown in FIG. 15A, the lower tip of the engaging portion 21 is inserted into the engaging hole 14 as shown in FIG. Thus, the door 23 can be held in this open position. Further, since the flap 12 is inclined in the state of FIG. 15B, the flap 12 easily slips and comes off with respect to the engagement portion 21 of the lock member 19 when the door 23 is closed from the state of FIG. It becomes a state. Therefore, as shown in FIGS. 13 and 15, the engagement portion 21 may be provided with a recessed portion 22 so that the inner side of the engagement hole 14 of the flap 12 is caught by the recessed portion 22.

  In the up / down operation of the lock member 19, although not shown in the figure, a structure having a click feeling that urges the lock member 19 to either side using the torsion spring or the like at the center position of the vertically movable distance. Alternatively, the sphere may be biased with a push spring, and a configuration may be provided in which the sphere is fitted into the indented portion at a predetermined position and the position is maintained to improve the operational feeling. Further, it is better to be able to perform not only the push / pull operation with the hand but also the operation with the toes of the foot.

  In the above description, the configuration has been described in which the locking condition between the main body device a and the stopper device b is increased on the main body device side of the door stopper device, but it is possible to improve both the locking conditions on the stopper device side. It is. As an example of the configuration, as shown in FIG. 16, a spring member 11 is inserted between the base seat 13 and the flap 12 of the stopper device b, and the flap 12 receives the weight of the flap 12 with a force that is barely lifted. It is good to set as follows. Then, the operation of lifting the flap 12 when the main body device a approaches the stopper device b is facilitated.

  FIG. 16 shows a configuration in which a torsion spring is inserted as the spring member 11 between the flap 12 and the base seat 13, and shows a state in which the flap 12 is lifted by being attracted by a magnetic force. Moreover, the kind and the incorporating method of the spring member 11 in this case are not specifically limited. However, since the weight of the flap 12 itself is not so heavy and it must be held in a state of being in close contact with the surface of the base seat 13 at normal times, a very weak spring member 11 is incorporated. Therefore, the spring member 11 completely enters the inside of the flap 12 and the base seat 13 so that the spring member 11 does not break due to other external forces such as interference of the suction port of the cleaner with the flap 12 during cleaning. It is necessary to arrange in the state.
