1. Field of the Invention
The present invention relates to a door opening/closing device configured to move a door relative to a housing.
2. Related Art
There is known a cabinet of which a door is moved by a door opening/closing devices mounted on an inner surface of a side wall of a housing in order to facilitate the opening and closing operation of the door relative to the housing (see Japanese Patent Application Laid-Open No. 2008-538938 and Japanese Patent Application Laid-Open No. 2004-339906). The door opening/closing device has two links between the housing and the door and serves to determine the attitude of the door when opening and closing the door.
When the mounting position of the door opening/closing device onto the side wall of the housing, the door in the closed state may be displaced from the housing or skewed. In order to solve this problem, the door opening/closing device needs to be mounted at the proper position of the housing. While a measuring rod is used to measure the position of the door opening/closing device, the door opening/closing device is fixed to the side wall of the housing. Or, a positioning part is provided in the door opening/closing device and used to fix the door opening/closing device to the side wall of the housing. With such a work, the door opening/closing device can be mounted at the proper position of the housing.
However, the mounting work while measuring the position of the door opening/closing device is troublesome. If a positioning part is provided in the door opening/closing device, the positioning work is facilitated. However, while the door opening/closing device is mounted on the housing with use of a fastening member such as screw, the door opening/closing device needs to be held continuously so as not to be displaced, and the door opening/closing device may be displaced during this work.
Then, the present invention aims to provide a door opening/closing device with a support member and a support member for a door opening/closing device, the support member being capable of positioning the door opening/closing device at a proper position in the housing and facilitating the mounting work of the door opening/closing device onto the housing.
BRIEF SUMMARY OF THE INVENTIONIn order to solve the above-mentioned problems, an aspect of the present invention is a door opening/closing device with a support member comprising: the support member which is mountable on a housing; and a door opening/closing device which is mounted on the support member and configured to move a door relative to the housing, wherein the support member has a first positioning part for positioning at a front surface of one of an upper plate and a side wall of the housing or one of a bottom plate and a side wall of the housing, and a second positioning part which is able to be placed against the other of the upper plate and the side wall of the housing or the other of the bottom plate and the side wall of the housing.
Another aspect of the present invention is a support member for a door opening/closing device for moving a door relative to a housing, wherein the support member is mountable on the housing and comprises a first positioning part for positioning at a front surface of one of an upper plate and a side wall of the housing or one of a bottom plate and a side wall of the housing, and a second positioning part which is able to be placed against the other of the upper plate and the side wall of the housing or the other of the bottom plate and the side wall of the housing.
According to the present invention, the support member is able to be positioned at the proper position in the housing and thereby, the door opening/closing device mounted on the support member is also able to be positioned at the proper position in the housing. Besides, as the door opening/closing device is mounted on the housing via the support member, it is possible to facilitate the mounting work of the door opening/closing device onto the housing.
The above and other objects and features of the invention will appear more fully hereinafter from a consideration of the following description taken in connection with the accompanying drawing wherein one example is illustrated by way of example, in which;
With reference to the drawings, a door opening/closing device with a support member according to an exemplary embodiment of the present invention will be described in detail below. The door opening/closing device with a support member is mounted on a housing 1 of furniture such as a cupboard in such a manner that a door can open and close relative to the housing 1. The housing 1 is open in a front surface and this opening is closed by the door 2 indicated by the chain double-dashed line in
The door 2 has a door knob (not shown) so that a person moves the door 2 upward to open the door 2 and downward to close the door 2. In order to open a heavy door 2 by a small force, the door opening/closing device 4 has a built-in spring for generating a force to assist the opening operation of the door 2. Besides, in order to attenuate the impact when opening and closing the door 2, the door opening/closing device 4 is provided with a damper for damping the opening and closing operations of the door 2. When opening and closing the door 2, the door 2 moves upward and downward while keeping its own attitude approximately in parallel with the housing 1. In order to parallel movement of the door 2, the door opening/closing device 4 has two links (auxiliary arm 6 and arm 7) that are approximately in parallel with each other and equal in length. The detailed structure of the door opening/closing device 4 will be described later.
The housing 1 is formed like a box and has an upper plate 1a, a pair of (left and right) side walls 1b, bottom plate 1c and a back plate 1d. On inner surfaces of the left and right side walls 1b of the housing 1, a pair of left and right door opening/closing device 4 is mounted, respectively. In order to synchronize the operations of the door opening/closing devices 4, the paired door opening/closing device 4 are connected by a connecting rod 5 as a connecting member.
As illustrated in
The paired door opening/closing devices 4 are mounted on the housing in the following manner. First, a worker fixes the left and right support members 8 to the lower surface of the upper plate 1a of the housing 1 with use of a fastening member such as a screw. At this time, the worker positions the support members 8 in such a manner that the front surface side of each of the support members 8 is flush with the front surface of the upper plate 1a (arranged in the same plane) and the side surface side of the support member 8 abuts to the side wall 1b. Then, the worker takes with both hands the door opening/closing devices 4 in pair which are already connected to each other by the connecting rod 5, fit the engaged part 21 of each of the door opening/closing devices 4 to the engaging part 12 of the support member 8 and slides the door opening/closing devices 4 in one direction (in the depth direction of the housing 1). Then, the paired door opening/closing devices 4 are mounted on the paired support members 8. When the door opening/closing devices 4 are mounted on the support members 8, the door opening/closing devices 4 are positioned at the proper positions of the housing 1. After that, as shown in
According to the present embodiment, when fixing the door opening/closing devices 4 to the side walls 1b of the housing 1 with use of the fastening members 13, the paired door opening/closing devices 4 are supported by the paired support members 8. Therefore, the paired door opening/closing devices 4 can be prevented from falling down even if they get off the worker's hands and the screwing work can be performed by one worker. On the other hand, if the door opening/closing devices 4 are directly mounted on the housing 1 without the support members 8, the worker has to keep holding one door opening/closing device 4 while screwing the door opening/closing device 4 to the side wall of the housing 1. Therefore, the screwing work is difficult.
The structure of the support member 8 is described below. As illustrated in
The body part 10 is formed like a rectangular plate. This body part 10 serves to position the support member 8 relative to the housing 1. Specifically, one front-side side (first positioning part) 10a of the body part 10 is positioned to be flush with the front surface of the upper plate 1a of the housing 1. As this one side 10a is positioned to be flush with the front surface of the upper plate 1a of the housing 1, the support member 8 can be positioned in the depth direction of the housing 1. Besides, one lateral-side side 10b (second positioning part) of the body part 10 is placed to abut against the side wall 1b in such a manner that the support member 8 is in parallel with the side wall 1b. The front-side side 10a and the lateral-side side 10b of the body part 10 form a right angle. As the lateral-side side 10b of the body part 10 abuts to the side wall 1b of the housing 1, the support member 8 is positioned in the horizontal direction of the housing 1. Needless to say, the support member 8 is positioned in the vertical direction of the housing 1 by attaching the body part 10 to the lower surface of the upper plate 1a.
Here, as far as the support member 8 can be positioned relative to the housing 1, the front-side side 10a and the lateral-side side 10b of the body part 10 need not be formed linearly. For example, a recess may be formed in the front-side side 10a of the body part 10, or the front-side side 10a may be formed protruding. Or, a plurality of jutting parts may be formed in the lateral-side side 10b of the body part 10 so that the jutting parts can abut against the side wall 1b. With these plural jutting parts, the support member 8 can be positioned in parallel with the side wall 1b.
As illustrated in
The arm 7 is connected to a running member 34 via a link arm 33. As the arm 7 rotates, the running member 34 moves linearly in the left and right direction in
On an upper part of the running member 34, a damper 36 is provided for attenuating the impact which is generated by opening the door 2. The damper 36 may be a linear damper using viscous fluid or a friction damper using friction. On a lower part of the running member 34, a damper 37 is provided for attenuating the impact which is generated by closing the door 2. This damper 37 may be also a linear damper or friction damper.
On the connecting member 32, a door-side mounting piece 38 fixed to the door 2 is mounted detachably. The door-side mounting piece 38 has a built in lever 39 which is biased by a coil spring (not shown). The lever 39 is configured to be movable vertically relative to the door-side mounting piece 38. When the door-side mounting piece 38 is attached to or detached from the connecting member 32, the lever 39 moves upward or downward automatically so as to enable mounting of the door 2 through one-touch operation.
At an axial end of the connecting rod 5, four recesses 5a are formed for fitting the four protrusions 42b of the joint 42 thereinto (see
The present invention is not limited to the above-described embodiment and may be embodied in various modified forms without departing from the scope of the present invention. For example, the support member is not limited to be mounted on the upper plate of the housing, but may be mounted on a side plate of the housing. In addition, the support member may be mounted at a corner of the bottom plate of the housing for positioning at the bottom plate and the side wall. Further, the door opening/closing device may be slid in the vertical direction thereby to be mounted on the support member. Furthermore, the support member may be formed like a hook so that the door opening/closing device can be hooked and mounted on the support members.
The step of mounting the door opening/closing device on the side wall of the housing by a fastening member such as a screw may be omitted. When the door is light or door front is narrow, the door opening/closing device may be supported only by the support member.
The structure of the door opening/closing device is not limited to those according to the above-described embodiment as far as the attitude of the door is fixed. For example, a door opening/closing device may be used which has one link mounted rotatable on the housing, a slider sliding relative to the one link and a door mounted rotatable on the slider (see International Publication No. WO2010/097996).
The present invention is not limited to the above described embodiments, and various variations and modifications may be possible without departing from the scope of the present invention.
This application is based on the Japanese Patent application No. 2011-166256 filed on Jul. 29, 2011, entire content of which is expressly incorporated by reference herein.
