Description

  The present invention relates to a door appliance and a door stop device of a door stop device. More specifically, a shock absorber, which is provided on a door device attached to the door side, is a portion that contacts a movable body provided on a floor device that is paired with the door device, due to friction with the movable body. The present invention relates to a door appliance and a door stop device of a door stop device that prevent peeling or falling off.

  A door stop device is generally used in which when the door is opened, the door is fixed at an appropriate opening position so that the door does not hit a wall surface or another door. Further, in recent years, a device that can move a movable part serving as a stopper by using magnetic force to automatically fix an opened door has become widespread (see JP-A-11-287062, etc.).

  The inventor of the present application further improved such a door stop device that can automatically fix the door, and proposed a door stop device as shown in Patent Document 1. The floor appliance of this door stop device is formed so thin that it does not form a step that disturbs even if it is fixed to the floor as it is, and when the movable body falls into the receiving recess, the impact sound is heard. Means for reducing are provided. Furthermore, the door appliances that are paired with the floor appliances are also provided with means for reducing the impact sound at the location where the movable body to be magnetically applied hits.

(Function)
The operation of the door appliance and door stop device of the present invention will be described. Here, the constituent elements used in the description are assigned in correspondence with the reference numerals given to the respective parts in the embodiments described later. These reference numerals are the same as the reference numerals described in the claims of the claims. Similarly, it is only for the purpose of facilitating understanding of the contents, and the meaning of each component is not limited to the above-described parts.

The door device (3) is attached to the lower side surface or bottom surface of the door (5) by screws or the like. In addition, the floor appliance (2) that is paired with the door appliance (3) also has a predetermined position on the floor (4) surface on the path along which the door appliance (3) moves as the door (5) opens and closes ( It is fixed by screwing or the like as it is at a position where it is stopped and fixed at a predetermined opening when the door (5) is opened.
When the door (5) is opened and the door appliance (3) is moved to the position where the floor appliance (2) is provided, the magnetic force of the magnet (36) of the door appliance (3) will cause the floor appliance (2 ) Of the movable body (23) is instantaneously caused and hits and adheres to the surface of the buffer (34) (the state in which the movable body (23) adheres to the buffer (34) by magnetic force can also be referred to as magnetic adhesion). At this time, the impact when the movable body (23) hits is reduced by the action of the buffer body (34), and noise can be reduced. In addition, the relative movement of the door device (3) and the floor device (2) due to the movement of the door (5) causes the contact portion (39) to contact the tip of the movable body (23), thereby the door ( 5) Stop.

  The buffer (34) has an opening that leads to the surface of the magnet (36) along the direction in which the door device (3) moves relative to the floor device (2) when the door (5) is opened and closed ( 340) is provided in the opening (340) because there is no shielding portion between the magnet (36) and the movable body (23), and the buffer body (34) is interposed. In comparison, the movable body (23) can be caused (pulled up) with a stronger force, and the fixing force when bonded by magnetic force is also stronger. In addition, since the area where the movable body (23) and the buffer body (34) come into contact with each other is reduced by the amount of the opening (340), the buffer body (34) is displaced due to being hardly caught. It can prevent peeling.

  The door (5) is fixed in this state and can be kept open. Fixing of the door (5) by the door stop device (1) can be released simply by moving the door (5) in the closing direction. That is, when the movable body (23) is adhered to the buffer body (34) by the magnetic force as described above, when the door (5) is moved in the closing direction, the movable body (23) with respect to the buffer body (34) is moved. Bonding is released. At this time, as the door device (3) moves, the movable body (23) is pushed down to reduce the angle (elevation angle), but while the movable body (23) is in contact with the buffer body (34), The buffer (34) is rubbed or dragged with a strong frictional force due to the movable body (23) being bonded by a magnetic force. However, since the shock absorber (34) is stopped by the stop portion (351), it can be prevented from being displaced (or following) and being peeled off even when pulled. Then, the movable body (23) separated from the door appliance (3) is rotated downward and is accommodated in the movable body accommodating recess (22) of the base body (20). Furthermore, if the door (5) is moved in the closing direction, it can be closed at the original closed position.

  According to the present invention, in a door contact device configured with a floor appliance attached to the floor in a pair with a door appliance attached to the door side and the door appliance, the door appliance is provided with the floor appliance. It is possible to prevent the shock absorber against which the movable body hits from being peeled off or dropped due to repeated pulling by the frictional force with the movable body, particularly when the door is closed.

The lower surface 33 is provided with a recess 35 for receiving and fixing two rubber-made plate-like cushioning bodies 34. The bottom shape and depth of the recess 35 are formed such that the surface of the fixed buffer 34 is substantially flush with the lower surface 33. A spacer 350 for forming an opening 340 between the two cushions 34 is provided in the center of the side of the concave portion 35 on the tip side of the magnetized portion 31. Moreover, the stop part 351 which forms the said side part of the recessed part 35 is a part which stops the shift | offset | difference of each buffer body 34. FIG. Note that the width of the movable body 23 is set to be smaller than the entire width of the two buffer bodies 34, and the movable body 23 is accommodated inside the both buffer bodies 34.

  The material used as the buffer body 34 (the same applies to the buffer body 390 described later) is not particularly limited as long as it has buffering properties. For example, rubber, various synthetic resins (for example, foamed polyurethane resin, etc.) ), Paint, non-woven fabric, cork and the like. The attachment can also be performed by fitting, adhesion (application, dipping) or the like in addition to adhesion by an adhesive.

A magnet housing portion 37 for housing and fixing a magnet 36 that is a permanent magnet is provided on the inner side of the recessed portion 35 of the magnetized portion 31. The magnet 36 used in the present embodiment is a so-called button type (disc type), and the magnet housing portion 37 is also a space portion having the same shape.

(Work)
The operation of the door stop device 1 will be described with reference to FIGS.
First, the floor appliance 2 is attached to the surface of the floor 4, and the door appliance 3 is attached to the side surface of the door 5. The installation of the floor appliance 2 and the door appliance 3 is by screwing using wood screws 6. Further, the mounting height of the door appliance 3 with respect to the door 5 (height from the surface of the floor 4) is, as shown in FIG. 2, when the movable body 23 is caused by a magnetic force and adhered to the buffer body 34. In order to increase the fixing force, the surface of the movable body 23 and the surface of the buffer body 34 are preferably adjusted so as to be in contact with each other in a substantially parallel state.

  By the way, in recent years, from the viewpoint of improving the indoor environment by circulating indoor air, a gap (opening) between the lower end edge of the door and the floor surface may be slightly larger. In order to cope with this, the through-hole 32 of the attachment part 30 of the door device 3 is formed long in the vertical direction, and the range in which the mounting height of the door device 3 can be adjusted is increased. ing. In addition, even after the wood screw 6 is once screwed, there is an advantage that the mounting height of the door appliance 3 can be finely adjusted without changing the screwing position.

  When the door 5 is opened and the door appliance 3 is moved to the position where the floor appliance 2 is provided through the state shown in FIG. 1, the movable body of the floor appliance 2 is moved by the magnetic force of the magnet 36 of the door appliance 3. 23 is instantly caused to hit the surface of each buffer 34 and adhere. The impact when the movable body 23 hits at this time is reduced by the buffering action of the buffer body 34, and noise can also be reduced. Further, the door 5 moves in the opening direction, and the buffer body 390 of the stop portion 39 hits the tip of the movable body 23 due to the relative movement of the door appliance 3 and the floor appliance 2 accompanying the movement, whereby the door 5 It stops and is fixed (state of FIG. 2).

  In addition, since the opening part 340 which leads to the magnet 36 surface is provided between the buffer bodies 34 along the direction in which the door appliance 3 moves relative to the floor appliance 2 when the door 5 is opened and closed, In the opening 340, there is no shielding portion between the magnet 36 and the movable body 23. Therefore, the movable body 23 can be caused with a stronger force than the portion where the buffer body 34 is interposed, and the fixing force when magnetized is also stronger. Furthermore, since the area where the buffer body 34 and the distal end portion of the movable body 23 come into contact with each other is reduced by the amount of the opening 340, the distal end portion of the movable body 23 is less likely to be caught, resulting from this. The buffer 34 can be prevented from being displaced or peeled off.

The door 5 is fixed in this state, and can maintain the open state. In addition, since the satin-like unevenness 231 is processed on the upper surface of the movable body 23, the shift of the bonding portion between the buffer body 34 and the movable body 23 is more firmly prevented, and the fixing force is increased.
And fixation of the door 5 by the door stop apparatus 1 can be cancelled | released only by moving the door 5 in the closing direction. That is, when the door 5 is moved in the closing direction from the state in which the movable body 23 is adhered to the buffer body 34 by magnetic force as described above, the door appliance 3 also moves in the same manner to bond the movable body 23 to the buffer body 34. Is released.

  At this time, the movable body 23 is pushed downward and the angle (elevation angle) decreases with the movement of the door appliance 3. However, while the movable body 23 is in contact with the buffer body 34, the movable body 23 is Coupled with the strong frictional force caused by the magnetic force and the effect of the satin-like unevenness 231, the surface of the buffer body 34 is rubbed and pulled (the movable body 23 itself does not move, but the movable body 23 is buffered). By moving relative to the body 34). However, since each buffer 34 is stopped by the stop portion 351 of the recess 35, it can be prevented from being displaced or peeled off even if it is pulled. The movable body 23 away from the door appliance 3 is rotated downward and is accommodated in the movable body accommodating recess 22 of the base body 20, and does not get in the way. If the door 5 is further moved in the closing direction, it can be closed at the original closed position.
