1 DOOR CLOSER
2 BACKGROUND OF THE INVENTION
3 1. Field of the Invention
4 The present invention relates to a door closer, and more particularly
relates to a door closer that is connected between a door frame and a door
panel
6 to assist the door panel to move backwardly the original position
relative to the
7 door frame and can be assembled between a door frame and a door panel of
8 different sizes.
9 2. Description of Related Art
With reference to Fig. 11, a conventional door closer is connected
11 between a door frame 60 and a door panel 61 and has an elongated tube
70, a
12 connecting base 76 and a linking set 72. The elongated tube 70 is
hollow, is
13 connected to a top of the door panel 61 and has a top side, a track slot
and a
14 sliding block 71. The track slot is formed in the top side of the
elongated tube 70.
The sliding block 71 is slidably mounted in the track slot of the elongated
tube 70
16 and had a top end extending out of the top side of the elongated tube
70. The
17 connecting base 76 is securely mounted on a side of the door frame 60
and has a
18 bottom side.
19 The linking set 72 is connected to the elongated tube 70 and the
connecting base 76 and has an arm pipe 73 and a linking shaft 74. The arm pipe
21 73 is hollow, is connected to the sliding block 71 of the elongated tube
70 and has
22 a connecting end and a mounting end. The connecting end of the arm pipe
73 is
23 pivotally connected to the top end of the sliding block 71. The linking
shaft 74 is
CA 02888323 2015-04-20
2
1 mounted in the arm pipe 73, is pivotally connected to the connecting base
76 and
2 has an inserting end and a pivot end. The inserting end of the linking
shaft 74 is
3 inserted into the arm pipe 73 via the mounting end of the arm pipe 73 and
is
4 securely connected to the arm pipe 73 by a fastener 75. The pivot end of
the
linking shaft 74 is pivotally connected to the bottom side of the connecting
base
6 76. In addition, the position of the inserting end of the linking shaft
74 can be
7 adjusted relative to the arm pipe 73 to change the total length of the
linking set
8 72.
9 In use, after the conventional door closer is connected to the door
frame
60 and the door panel 61, when the door panel 61 is open to rotate relative to
the
11 door frame 60, the linking set 72 is rotated relative to the connecting
base 76 by
12 the sliding block 71 moving in the track slot of the elongated tube 70.
In addition,
13 the linking set 72 can be used to limit the rotating angle of the door
panel 61
14 relative to the door frame 60. Furthermore, when the door panel 61 is
closed to
move backwardly to the door frame 60, the sliding block 71 is moved in the
track
16 slot in an opposite direction, and this can enable the linking set 72 to
assist the
17 door panel 61 to move backwardly the original position.
18 The linking set 72 of the conventional door closer can be adjusted to
19 change the total length of the conventional door closer, and this can
enable the
conventional door closer to assemble on the door frame 60 and the door panel
61
21 of different sizes. However, based on the cost and operation
considerations of the
22 conventional door closer, the adjusting range of the linking set 72 of
the
23 conventional door closer is limited and cannot be assembled on various
sizes of
CA 02888323 2015-04-20
3
1 door frame 60 and door panel 61. Therefore, different sizes of linking
sets 72 are
2 needed to be manufactured to use on various sizes of door frame 60 and
door
3 panel 61, and this will increase the cost of using the conventional door
closer and
4 will limit the practicality of the conventional door closer.
Therefore, the invention provides a door closer to mitigate or obviate the
6 aforementioned problems.
7 SUMMARY OF THE INVENTION
8 One aspect of the present invention is to provide a door closer that is
9 connected between a door frame and a door panel to assist the door panel
to move
backwardly the original position relative to the door frame and can be
assembled
11 between a door frame and a door panel of different sizes.
12 The door closer in accordance with the present invention has a fixing
set,
13 a bidirectional set and an extending set. The fixing set has an
elongated tube. The
14 elongated tube has two opposite sidewalls and an opening. The
bidirectional set

9 closer in accordance with the present invention between a door frame 60
and a
door panel 61, the total length of the extending set 30 can be adjusted by the
11 engagement between the positioning teeth 314 of the guiding track 31 and
the
12 engaging teeth 332 of the locking board 33 and has a wider range of
adjustment,
13 and this can enable the door closer in accordance with the present
invention to
14 assemble between the door frame 60 and the door panel 61 of different
sizes.
Then, the cost of using the door closer in accordance with the present
invention
16 can be reduced and the practicality of the door closer can be promoted.
17 After adjusting the total length of the extending set 30 to fit with the
size
18 of the door frame 60 and the door panel 61, the directional set 20 is
mounted in
19 the elongated tube 11 via the first end 115 of the elongated tube 11 or
the second
end 116 of the elongated tube 11 according to the size and the open direction
of
21 the door panel 61. The fixing set 10 is mounted in a recess of the door
panel 61
22 that is formed in a top of the door panel 61 to enable the first end 115
of the
23 elongated tube 11 to mount adjacent the hinges between the door frame 60
and

14
1 the door panel 61 as shown in Fig. 10. After the above-mentioned
assemble, the
2 buffering set 40 can be mounted between the door frame 60 and the door
panel 61
3 adjacent the hinges. In addition, the connecting panel 34 of the
extending set 30
4 is securely connected to a bottom side of the door frame 60. In
operation, when
the door panel 61 is rotated relative to the door frame 60 to being in a
closed
6 condition or in an open condition, the extending set 30 can be rotated
relative to
7 the door frame 60 by the bidirectional set 20 moving in the elongated
tube 11 of
8 the fixing set 10.
9 With reference to Figs. 9 and 10, during the door panel 61 is rotated
relative to the door frame 60 to move at an intended open position, the
11 bidirectional set 20 is moved by the extending set 30 toward the first
end 115 of
12 the elongated tube 11. When the bidirectional set 20 is moved across the
13 switching set 50, the engaging rod 26 is pushed upwardly relative to the
body 23
14 by abutting along the guiding face 521 of the switching mount 52. After
the
engaging rod 26 is moved across the guiding face 521 of the switching mount
52,
16 the engaging rod 26 will be moved downwardly to abut along the holding
face
17 522 of the switching mount 52 by a pressing force of the elastic slice
27. Then,
18 the bidirectional set 20 can be positioned between the buffering block
42 and the
19 switching mount 52, and this can held the door panel 61 stably at the
intended
=
open position. When the door panel 61 is rotated to move backwardly to the
door
21 frame 60, the engaging rod 26 will be moved with the bidirectional set
20 by the
22 extending set 30 to across the switching mount 52, and the extending set
30 can
23 provide an assist effect to the door panel 61 to move backwardly the
original
