In addition, the previous cam version 5 has a plurality of collecting portions 51 (three in the present embodiment) in the outer periphery of the yen. It is a structure which stops rotation of the electric cam board 5 by the coarse member 8 which has the coarse piece 8B which is made and is joined to the collection part 51. When the rotation of the cam plate 5 is stopped, the rotation of the electric axis 3 on which the previous cam plate 5 is fixed is stopped. In other words, the engaging means for preventing rotation of the electric cam plate 5 is constituted by the electric jaw member 8 and the electric drawing part 51, and according to the locking means. The axle 3 can be fixed to set the elasticity of a predetermined tape spring.

Therefore, along with making the depression 20 of the extent that the electric cam plate 5 can be accommodated on the surface of the main body case 2 having the electric cam plate 5, the electric main body of the electric car 3 is formed. A spring member is mounted between the surface 2a of the case and the electric cam plate 5, and the electric cam plate 5 is supported by being spaced apart from the electric depression 20 to support the electric cam plate 5.

It is a structure which disengages the electrical coupling in the direction which contacts 51.

The former jaw portion 8 is fitted with the support shaft 9 and abuts on the electrical drawing portion 51 by the spring material 10 thereon, which is held by the rotating material on the main body case 2. It is biased in the direction to swell, and it is supported by rotation in the opposite direction.

For this reason, the electric jaw member 8 is always in contact with the cam surface of the electric cam plate 5. In addition, when the former cam plate 5 is pressed and the engagement relationship with the former nail member 8 is released, the electric cam plate 5 is rotated to apply a predetermined elasticity. By rewinding the electric cam plate 5 while supporting one end 8A of the jaw member 8 with a finger, it can be fixed to a new engagement position.

On the surface of the electric cam plate 5, a handle 52 is formed, which makes it easy for an operator to press, hold, or operate. Reference numeral 53 is a fixing hole for fixing the electric cam plate 5 to the screw hole attached to the surface 2a of the main body case.

In order to install the electric sliding door closer 1A in the wall or the like, an installation hole 23 is made in the rear surface 2b of the main body case 2. 22 is a hole provided in the surface 2a, and is a hole for inserting a screwdriver for tightening a screw member passing through the electric installation hole 23, which is larger than the installation hole 23.

The front door closer 1A for the electric sliding door can be fixed not only to the surface 2b part but also from the bottom 2c part, so that the opening part of the electric bottom 2c part can be fixed. The mounting hole 24 is also made in 2c, and both the surface 2b and the bottom surface 2c of the main body case 2 can be installed.

Moreover, in order to push the cam plate 5 attached to one end 3A of the support shaft 3 which penetrates the main body case 2 to the surface 2a side of the electric main body case 2, a spring member is attached to the electric depression 20. Doing.

As the former spring member, in this embodiment, a conical spring or a contact sheath spring SW is employed. Therefore, since the depth of the former depression 20 may be small, the cone spring or the disc spring SW which exhibits predetermined elasticity is used, and it is possible to push the support shaft 3 with a predetermined pressing force. have. Moreover, since the depth of the former depression 20 may be small, it is possible to shorten the length of the axial direction, and it can be said that it is a compact door closer.

In addition. The recessed part 21 is also provided in the back surface 2b part of the main body case 2. The front recess 21 is brought into close contact with the wall of the front of the front of the electric front when the end 3B of the rear of the front axis 3 does not protrude from the back of the front 2b. It is suitable because it can fix door closer 1A for sliding door.

In other words, when the electric axis 3 and the cam plate 5 are pushed in as much as the deformation amount of the conical spring or the plate spring SW, the chamfer 51 of the cam plate 5 is removed from the electric jaw member 8. It is designed so that it is possible to rotate the cam plate 5 in this state. In other words, it is possible to adjust the elasticity by closing the sliding door of the previous door closer 1A.

The sliding door closer 1A according to the present invention can be easily adjusted to the desired elasticity by the simple operation of pressing the cam plate 5 to rotate the predetermined amount and returning the above structure.

Next, the sliding door closer 1B according to FIG. 2 will be described. In addition, the code | symbol of each part abbreviate | omits the characteristic member and uses the code | symbol same as the code | symbol demonstrated above.

The electric door closer 1B for sliding doors is a sliding door closer for disengaging the locking means by moving in the direction of removing the shaft, and the spring body 4 housed in the box-shaped body case 2A and its body case 2A, and the electric (Prev) One end of the main shaft spring 4 and the front axis 3, which is fixed by rotating materials through the front surface 2Aa and the back 2Ab of the front body case 2A, and the front axis 3 is fixed. A drum 6 having a cam plate 5A and a frontal spring 4 embedded in the one end 3A which protrudes from the surface 2a of the front body case 2, and the end 3A on the side thereof; The drum 6 has a wire 7, which is wound around and rolled up. In addition, as mentioned above, the hook 70 attached to the front part of the wire 7 is fixed to the sliding door 30, and it is the same to apply to the sliding direction of the sliding door.

In addition, in order to install the sliding door closer 1B in a wall or the like, an installation hole 23 is provided in the rear side 2b of the front, and an installation hole is provided in the projection part of the bottom surface 2c. 24 is also the same as that described for the sliding closure 1A.

Next, rotation prevention of the spring 4 is demonstrated in this embodiment. A plurality of iron portions 25 are formed on the surface 2Aa of the main body case 2A and formed on the surface 5Aa of the electric cam plate 5A to join the plurality of iron portions 11. In other words, at the position where the former convex portion 25 and the former convex portion 11 engage, the front surface 2Aa of the front body case 2A and the back surface 5Aa of the front cam plate 5A. Is in close contact.

Moreover, the other end 3B of the electric axis penetrating the main body case 2A protrudes from the back 2Ab of the electric main body case 2A, and the one end of the protruding end 3 Surface 2Aa of main body case 2A, which is fitted with a spring member, for example, a conical spring or a plate spring SW, on the part 3B, and the cam plate 5A in which one direction of the electric axis 3 is mounted on the end part 3A. It pushes in a direction and pushes in a direction.

In addition, by making a handle 54 on the electric cam plate 5A, holding the electric handle 54 and raising it, the electric cam plate 5 was transferred to the electric cone spring or plate spring SW. It is possible to lift by the electric main body case 2A and to carry it out against resistance.

To this end, it is possible to squeeze and lift the electric handle 54 and push the convex portion 11 of the electric cam plate 5A out of the main portion 25 of the electric body case 2A. It is possible to rotate the electric cam plate 5A.

In addition, when the convex part 11 reaches the next recessed part 25 by rotating the electric cam plate 5A by a predetermined angle, the electric grip part 54 is held tight. When the force is released, the electric cam plate 5A is urged toward the surface 2Aa of the electric body case 2A by the elasticity of the electric cone spring or the disc spring SW, and the recesses and the convex parts. It is possible to engage the ridge. In this way, the recess 25 formed on the surface 2Aa of the main body case 2A and the convex part 11 made on the back 5Aa of the front cam plate 5A are precisely matched to each other. Since the cam plate 5A is fixed, it is possible to reliably prevent rotation of the support shaft 3 on which the cam plate 5A is mounted.

In the present embodiment, four round holes are formed on the surface 2Aa of the main body case 2A as recesses 25. In other words, four round holes 25a every 90 degrees. 25b, 25c, 5d are made.

In addition, in the cam plate 5A, two Y-shaped convex portions 11 (11a. 11b) are formed to fit in an electric hole. The former campane 5A has a spherical shape or a long Yen-like shape in which the end of the spherical shape is en-shaped. The former Y-shaped convex part 11a, 11b is provided in two places corresponding to the radial direction. Therefore, in the position indicated on the way, the Enho convex part 11a engages with the round hole 25a, and the Enho convex part 11b engages with the round hole 25d. When the cam plate 5A is lifted and rotated 90 degrees clockwise, the Y-shaped convex portion 11a engages with the round hole 25b, and the arc-shaped convex portion 11b engages with the round hole 25c. It is in one state and is fixed once again. At this time, once the cam plate 5A is lifted up and starts to rotate, the lifting force is not necessary because the Y-shaped convex portion rotates while sliding over the surface 2Aa of the main body case 2A. In addition, when the force reaches the next round hole by simply rotating without applying force in the lifting direction, the front convex part is rounded by the elasticity of the electric cone spring or the disc spring SW. It falls into the hole and is automatically fixed in position.

As the electric spring member, it can be used not only for the conical spring or the disc spring SW, but also for the coil spring. However, if the conical spring or the counter spring SW is used as in the present invention, the length in the axial direction can be shortened. The protruding length of the fore end 3B can be minimized.

In addition, since the recess 21 is formed in the rear surface 2Ab of the main body case 2A to accommodate the electric B projecting from the front rear surface 2Ab, the projection does not appear in the box-shaped main body case 2A rear surface.

Since the structure as described above, the sliding door closer 1B according to the present invention is a compact and simple configuration, and the elasticity to close the sliding door by the operation of rotating the predetermined amount by lifting the cam plate 5A while holding the handle portion. Is easily adjustable.

In addition, a convex part is made on the surface of the electric main body case, not a concave part, and a concave part is made on the back of the electric cam board instead of a concave part. It is also possible to engage the convex and the former recesses.

That is, the rotation of the electric axis is performed by engaging the recesses or convex parts made on the surface of the former body case with the recesses or recesses formed on the back of the electric cam plate. It is possible to set it as the structure which prevents.

If a plurality of screw holes 27 are formed at predetermined positions on the surface 2Aa of the main body case A, and the electric cam plate 5A is fixed from the locking screw 26, even if the material contacts the beat of something, The cam plate 5A does not turn and improves further.

As described above, according to the present embodiment, even when the elasticity of the spring spring is adjusted, the main body case and the cam plate are removed at every predetermined angle without any waste (in the present embodiment). Every 90 degrees), the electrical recesses and the convex parts are engaged and rotated to stop. Therefore, it is possible to obtain a sliding door closer that can be operated easily by a person without power and that can be operated safely even by a woman or an elderly person.

According to the present invention as described above, by moving the support shaft in front and rear of the axial direction through either the surface and the top surface of the main body case to release the locking means for preventing the rotation of the cam plate. It is possible to fix and rotate the cam plate by the simple operation of moving the support shaft in its axial direction, and to make it possible to open and close the door closer (opening / closing) that can be adjusted to any elasticity by simple operation.

According to the present invention, one end is fixed to a drill in which a spring is built, the wire is wound, the free end of the electric wire is connected to the sliding door, and the open sliding door is electric. In the door closer configured to be closed by the elasticity of the spring spring, the locking shaft penetrates the surface of the main body case and is held by the rotating material to the front or rear in the axial direction, and prevents the rotation of the cam plate. Because of the configuration of releasing the means, by a simple operation of moving the support shaft in the axial direction, it is possible to obtain a sliding door closer (opening / closing) for selecting and rotating the cam plate.
