Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door contact which is applied to a swing door and defines an opening limit of a door panel, and in particular, a support arm having a contact body fixed to the door panel fixed to a suspension frame side of a door frame. The present invention relates to a door stop of a form which is defined by an open limit of a door panel. Further, the present invention relates to a door stop in which the open position can be held by a magnet in the fully open position.

[0002]

2. Description of the Related Art This type of door stop can be found, for example, in Utility Model Registration No. 2507162. There, the support arm fixed to the upper end of the door panel, the magnet fixed to the projecting end of the support arm, and the catch body fixed to the wall form a door stop. The support arm is screwed to the door panel via the seat plate, and the mounting posture can be changed within the range of the long hole formed in the seat plate to adjust the contact posture between the magnet and the catch body. JP-A 1-226992
In the publication, a magnet is supported so that it can swing within a certain range,
A door stop is disclosed in which the contacting posture between the magnet and the catch body can be adjusted. In order to reduce the impact when the magnet violently collides with the catch, for example, it is fair to provide a shock absorbing rubber on the catch body side.
It is well known from the publication.

[0003]

The total opening angle of the swing door is roughly classified into 90 degrees and 180 degrees. In any case, the protruding length of the support arm for the door stop is determined by the distance between the wall to which the catch body is fixed and the fully open door panel (hereinafter,
It is set based on (opening gap). The open gap of the door panel is generally larger in the swing door having a full open angle of 90 degrees, and the open gap of the swing door having a full open angle of 180 degrees is extremely small. The former opening gap is equal to the distance from the center of the hinge to the wall to which the catch body is fixed, and in many cases, the wall is provided at a position away from the hinge. On the other hand, the latter opening gap is determined by how much the hinge center projects from the previous reference surface with the door panel surface at the closed position as the reference surface. As described above, since the opening clearance is greatly different between the case where the swing door has a full opening angle of 90 degrees and the case where the swing door has a full opening angle of 180 degrees, it is customary to provide a dedicated door stop for each of them in many cases. However, despite having the same door structure, it was necessary to prepare a dedicated product for each door unit. Further, in the conventional door stop, since the support arm and the magnet are provided on the door panel and the catch body is fixed to the wall, the mounting position of the support arm may be changed depending on the positional relationship between the wall and the door panel. It is necessary to change and adjust each time, and there is also a disadvantage that extra effort is required for adjustment.

Even when the opening gap is greatly different as described above, by changing the mounting posture of the linear support arm with respect to the door panel, the total opening angle of the door panel is 90 degrees and the total opening angle is 180 degrees. It is not impossible to share a door-to-door unit when it is a degree. However, when fixing the support arm to the door panel, there is probably no problem because the mounting position is closer to the door tip, but when fixing the support arm to the door frame, especially when the support arm is centered on the hinge. It is not possible to fix it near (suspending side). The full opening angle of the door panel is 180
This is because the support arm is tilted and attached to increase the opening angle when it becomes large, but at that time, the support arm abuts and interferes with the door frame.

An object of the present invention is to change the opening angle specification of a door panel simply by changing the mounting attitude and the mounting position of the support arm. Therefore, when the total opening angle of the door panels is greatly different, for example, the total opening angle is 90 degrees. It is to provide a door stop that can be used in common even when there is a large difference between 180 degrees and 180 degrees.

[0006]

A door stop according to the present invention includes an abutment body 4 fixed to a door panel 2 and an abutment body fixed to a suspension side of a door frame 1 and moved to an open position together with the door panel 2. It consists of a catch body 5 that receives 4 pieces. The catch body 5 includes a support arm 6 and a stopper 7 attached to the tip of the support arm 6. Support arm 6 for catch body 5
A notch 13 is formed on one side to avoid contact interference with the door frame 1. Thus, the mounting posture and the mounting position of the support arm 6 with respect to the door frame 1 are changed so that the receiving angle of the abutment body 4 by the catch body 5 can be changed.

The support arm 6 of the catch body 5 includes a first arm 11 having a fastening portion 10 at one end, and a second arm 12 projecting laterally from the other end of the first arm 11. The L-shaped escape portion 13 can be formed between the second arm 12 and the second arm 12.

A magnet 8 is provided on one of the stopper 7 and the abutment body 4, and a magnetic metal attraction piece 25 attracted by the magnet 8 is provided on the other side.

A magnet 8 is arranged inside the stopper 7.
The suction piece 25 provided on the abutment body 4 and the outer peripheral surface of the stopper 7 abutting on the suction piece 25 are each formed in a partial arc shape. Then, the arcuate peripheral surface of the attracting portion 19 of the magnet 8 can be located slightly inward of the outer peripheral surface of the stopper 7.

The abutment body 4 includes a pedestal 24 mounted on the door panel 2, and a suction piece 25 fixed to the pedestal 24.
The pedestal 24 integrally includes a plurality of mounting shafts 28. Then, the mounting shaft 36 is formed in the door panel 2, and the mounting hole 36 is formed.
It can be fixed in a retaining shape by a screw 38 screwed in a direction orthogonal to the axis of the mounting shaft 28.

[0011]

According to the present invention, the door stop is constituted by the abutment body 4 fixed to the door panel 2 and the catch body 5 fixed to the suspension base side of the door frame 1 to receive the abutment body 4. A notch 13 is formed on one side of the support arm 6 that supports the stopper 7 to avoid contact and interference with the door frame 1. Therefore, when the opening angle of the door panel 2 is large, the support arm 6 is not supported. The escape section 1 does not interfere with the frame 1 and the wall.
It can be avoided by 3. Therefore, when the total opening angle of the door panel 2 is greatly different, for example, the total opening angle is greatly different between 90 degrees and 180 degrees, the catch body 5
By changing the receiving angle of the abutment body 4 according to, the door stop can be commonly used in any case. Also,
Since the support arm 6 fixed to the suspension side of the door frame 1 receives the abutment body 4 fixed to the door panel 2, the catch body can be simply operated by changing the mounting posture and the mounting position of the support arm 6. It is possible to change the receiving angle specification of the abutment body 4 by 5.

According to the support arm 6 in which the L-shaped escape portion 13 is formed between the first arm 11 and the second arm 12 projecting laterally from the end portion of the first arm 11, the support arm 6 of the door panel 2 is provided. When the total opening angle is around 180 degrees, the first arm 11 can be brought close to the door frame 1 to prevent the entire support arm 6 from protruding significantly from the door frame 1. It is possible to prevent waste of material when the support arm 6 is punched and formed by a press machine.

Since the magnet 8 is provided on either one of the stopper 7 and the contact body 4, and the magnetic metal attracting piece 25 attracted by the magnet 8 is provided on the other side, the magnet 8 attracts the attracting piece 25. By doing so, the opened door panel 2 can be securely held and fixed at the fully opened position.

If the abutting surfaces of the suction piece 25 of the abutting body 4 and the stopper 7 made of a rubber molded product are each formed in a partially arcuate shape, the contact area between the suction piece 25 and the stopper 7 becomes large, and the stopper. The shock absorbing action of 7 is improved. Further, when the arcuate peripheral surface of the attracting portion 19 of the magnet 8 is located slightly inward of the outer peripheral surface of the stopper 7, when the contact body 4 collides with the stopper 7, the outer peripheral surface of the stopper 7 is It is possible to surely absorb the impact by elastically deforming, and to reliably prevent the contact body 4 from colliding with the magnet 8 and bouncing back.

The pedestal 24 and the suction piece 25 constitute the abutment body 4, and a plurality of mounting shafts 28 provided on the pedestal 24 are inserted into the mounting holes 36 of the door panel 2 and engaged therewith, and then the mounting shaft 28 is mounted.
Screw the screw 38 in the direction orthogonal to the axis of the
Since the pedestal 24 can be fixed in two directions orthogonal to each other by both the mounting shaft 28 and the screw 38 by securely fixing the pedestal 4, the pedestal 24 can be securely prevented from wobbling or floating from the door panel 2 during long-term use. The durability of the abutment body 4 is improved.

[0016]

1 to 8 show an embodiment of a door stop according to the present invention. In FIG. 2, reference numeral 1 is a door frame and 2 is a door panel. The door panel 2 is swingably and rotatably supported by a hinge 3 fixed to the door frame 1, and can swing between a closed position and a fully open position which is swung 90 degrees from the closed position. The door stop of the present invention is provided between the door frame 1 and the door panel 2 in order to define the opening limit of the door panel 2 and to hold and fix the open posture in the fully opened position.

The door stop comprises a contact member 4 fixed to the door panel 2 and a catch member 5 fixed to the suspension side of the door frame 1 and receiving the contact member 4 moved to the open position together with the door panel 2. . In FIG. 4, the catch body 5 includes a support arm 6 made of a press fitting, a stopper 7 and a magnet 8 attached to the tip of the support arm 6. The support arm 6 is configured in an L shape by a first arm 11 having a fastening portion 10 at one end and a second arm 12 laterally protruding from the other end of the first arm 11. An L-shaped escape portion 13 is formed between the first arm 11 and the second arm 12. Fastening part 10
Is provided with four screw holes 14, and each of these screw holes 14 is arranged in a rhombus shape. In either case of right-handed or left-handed, tapered screw seats are formed on the front and back of the screw hole 14 so that the support arm can be shared. When the door panel 2 is vigorously fully opened and a strong external force acts on the catch body 5,
In order to load a part of the force on the door frame 1 and protect the support arm 6, the first contact portion 15a is attached to the edge of the fastening portion 10.
And a second contact portion 15b that is cut off diagonally.

The stopper 7 is made of a roller-shaped rubber molded product, and has a screw insertion hole 16 formed vertically through the axial center and a recess 17 for accommodating the magnet 8 in the middle of the thickness direction. , The second arm 12 of the support arm 6 on the upper end surface
Is formed with a shallow seat portion 18. Magnet 8
Is a permanent magnet made of a sintered alloy integrally including a semi-circular attracting portion 19 and a quadrangular attaching portion 20. With the magnet 8 inserted into the recess 17 from the lateral outside, and loaded, and the second arm 12 of the support arm 6 is applied to the seat portion 18, the screw 2
1 through the screw insertion hole 16 and the nut 22 on the screw shaft.
The support arm 6, the stopper 7, and the magnet 8 are integrated by screwing. In this assembled state, the arcuate peripheral surface of the attracting portion 19 of the magnet 8 is located slightly inward of the outer peripheral surface of the stopper 7, as shown in FIG. This is because the impact generated when the abutment pair 4 collides with the stopper 7 is absorbed by elastic deformation of the outer peripheral surface of the stopper 7, and the abutment body 4 is prevented from bouncing.

In FIG. 5, the abutment body 4 comprises a pedestal 24 made of a plastic molded product and a suction piece 25 fixed to the pedestal 24. The pedestal 24 is provided with a partially arcuate receiving recess 26 for supporting the suction piece 25, and a pair of mounting shafts 28 are integrally provided on the left and right sides of the rear surface thereof. Engagement grooves 29 for the suction pieces 25 are formed on both sides of the opening of the receiving recess 26. A screw hole 30 is provided in the center of the receiving recess 26.
The basic shape of the mounting shaft 28 is a round shaft, and a V-shaped aligning groove 31 is formed in the upper surface of the mounting shaft 28. The adsorption piece 25 is made of a stainless steel plate material having magnetism and is formed in a partial arc shape, and the claw pieces 32 are bent and formed at both ends thereof. A screw insertion hole is provided in the center of the recess of the suction piece 25. In order to assemble the abutment body 4, a pair of left and right assembling holes 36 are formed at the upper end of the surface wall of the door panel 2, and an insertion hole 39 communicating with the assembling hole 36 from the upper end surface is formed in advance.

After inserting the mounting shaft 28 into the mounting hole 36,
The pedestal 24 is fixed by inserting the claw pieces 32 of the suction piece 25 into the engagement groove 29 and engaging them, and screwing the screw 37 into the door panel 2 from the outer surface side of the suction piece 25 (see FIG. 8). Further, the screw 38 inserted into the insertion hole 39 from the upper end surface of the door panel 2 is screwed into the mounting shaft 28 in a vertically penetrating manner, so that the abutment body 4 is retained and fixed (see FIG. 6). At this time, since the tip of the screw 38 can be guided to the center of the shaft by the alignment groove 31, the screw 38 can surely penetrate the mounting shaft 28 in the vertical direction. As described above, the pedestal 24 is formed by the screws 37 and 38 screwed in from two directions orthogonal to each other and the mounting shaft 28.
When the suction piece 25 is fixed, the pedestal 24 can be reliably prevented from floating and rattling from the door panel 2 during long-term use. The suction piece 25 is fastened by the screw 37 so as not to come off, but by forming a large hole for the screw 37, the suction piece 25 is fixed so that it can be loosely moved around the screw head in the fastened state. . This is to absorb the positional deviation with respect to the stopper 7 by allowing the suction piece 25 to move, so that the two pieces 7 and 25 are always brought into proper close contact with each other.

As shown in FIG. 3, the support arm 6 is applied to the upper frame of the door frame 1 with the longitudinal centerline P of the first arm 11 aligned with the line in the thickness direction of the door panel 2. The fastening portion 10 is fixed with screws 40 screwed in from the lower surface side. The total opening angle of the door panel 2 can be correctly set to 90 degrees only by specifying it. As shown in FIG. 6, when the contact body 4 is in contact with the stopper 7, the attraction surface of the magnet 8 faces the attraction piece 25 with a slight gap, and the attraction piece 25 is attracted by the magnet 8. Therefore, the door panel 2 can be held and fixed at the fully open position. When the door panel 2 is closed against the attraction force of the magnet 8, the attraction piece 25 is separated from the magnet 8 and the position holding action of the magnet 8 can be released.

When the opening angle of the door panel 2 is set to 180 degrees, as shown in FIG. 1, the support arm 6 is fixed to the door frame 1 while being inclined. In this attached state,
Since the escape portion 13 is provided between the first arm 11 and the second arm 12, it is possible to prevent the middle portion of the support arm 6 from abutting and interfering with the opening edge of the door frame 1 and the wall connected to the door frame 1. You can definitely avoid it. The distance c to the center of the fastening portion 10 in the fixed state is larger than the previous distance a, and the front-rear distance d is slightly larger than the front-rear distance b. As described above, when the support arm 6 is obliquely tilted and fixed to the door frame 1, the receiving position of the abutment body 4 by the stopper 7 is biased toward the wall, and the total opening angle of the door panel 2 is expanded. it can. By fixing the support arm 6 in an inclined state, the magnet 8
Although the adsorbing surface is displaced from the central portion of the adsorbing piece 25, since most of the peripheral surface of the adsorbing surface faces the adsorbing piece 25, the door panel 2 can be held in the open position without any problem. Of course, loosen the nut 22 so that the suction surface is the suction piece 2.
If the posture of the stopper 7 is changed so as to face the
The door panel 2 can be held more reliably in the open position. When the door panel 2 is received at an arbitrary opening angle between 90 degrees and 180 degrees, the receiving attitude of the abutment body 4 by the catch body 5 is changed by changing the mounting attitude of the support arm 6. To do.
