  However, in the device support structure disclosed in Patent Document 1, when the device is installed on the wall surface, first, the device is lifted, and the vertical fixing device is arranged between the device and the wall surface while supporting the device from the outside. Then, the device is supported on the wall surface, and then the external support is removed and the device is supported on the wall surface only by the vertical fixing device. Then, since the device is supported on the upper and lower supports so as to be mounted from above, the device slightly falls in the direction away from the wall surface, and accordingly, the upper and lower vibration isolation members bend. If this amount of deflection differs vertically, the vibration-proof performance of the device support structure will be impaired. In order to prevent this, it is necessary to bend the upper and lower vibration-proof members by the same amount of bending. However, for that purpose, the fixing position of the vertical fixing device must be determined in advance, and the device must be fixed to the vertical fixing device at the same time, and there is a problem that it takes time to install the device.

  Further, in the device support structure disclosed in Patent Document 2, all the support members are arranged on a straight line passing through the center of gravity of the device and fixed to the wall surface, and a vibration isolating member interposed between the support member and the base is provided. Since it expands and contracts in the direction of the straight line that passes through the center of gravity of the equipment, high anti-vibration performance can be obtained. However, in this case, the center of gravity of the device must be obtained before installing the device. In this case, for example, when the device is a water heater, it is not easy to obtain the center of gravity because instruments having various weights such as a combustor and piping are accommodated in a complicated arrangement. Thus, even in the device support structure of Patent Document 2, there is a problem that it takes time to install the device.

  The present invention has been made in view of the above points, and the problem is that in the equipment support structure in which the upper and lower sides of the equipment are supported on the wall surfaces by the upper and lower vibration-proof support devices, respectively. It is to facilitate installation.

  According to the second invention, since the upper connecting member is integrally connected to the shaft member, the upper connecting member and the shaft member can be made into one part, and the number of parts can be suppressed.

  According to a third invention, in the first invention, the upper support members protrude from the wall surface toward the device side with an interval in the axial direction of the shaft member, and extend downward from the upper end. The shaft member has a pair of side walls formed with notches, and both end portions of the shaft member are fitted to the notches so that the both side walls can be rotated around the axis of the shaft member. The upper elastic body is rotated integrally with the shaft member and the shaft, and the upper connecting member has a leaf spring wound around the outer surface of the upper elastic body, The leaf spring rotates around the axis of the shaft member by being integrated with the shaft member and the upper elastic body, thereby rotating around the axis of the shaft member.

Therefore, when the device is supported on the wall surface by the upper vibration isolating support device, first, the leaf spring and the device side are connected and the upper elastic member and the shaft member are attached to the leaf spring, while the upper support member is fixed to the wall surface. Then, the shaft member is hooked from above the notches. If it does so, a shaft member will be supported by the both-sides wall part, and an apparatus will be supported by the wall surface by the upper side vibration-proof support apparatus. Thus, since the upper support member and the upper connection member can be connected by a simple operation of hooking the shaft member from above the upper support member, the apparatus can be easily installed.

  According to the third invention, since the upper connecting member has the leaf spring, even when the device vibrates greatly due to an earthquake or the like, the vibration of the device is transmitted to the wall surface by the expansion and contraction of the leaf spring. Can be prevented.

  In a fourth aspect based on the first aspect, one end of the shaft member is fixedly supported by the upper support member, and the upper connection member is an elastic body also serving as the upper elastic body, The upper elastic body rotates around the axis of the shaft member.

  According to the fourth invention, one end of the shaft member is fixedly supported by the upper support member, and the upper connecting member is an elastic body that also serves as the upper elastic body. Therefore, when the device is supported on the wall surface by the upper vibration isolation support device, first, the upper connecting member and the device side are connected, while the upper support member is fixed to the wall surface, and then formed on the upper connecting member. The shaft member is passed through the through hole from the other end side. Then, the upper connecting member is supported by the shaft member, and the device is supported on the wall surface by the upper vibration isolating support device. Thus, since the upper support member and the upper connection member can be connected by a simple operation of passing the shaft member through the through hole of the upper connection member, the apparatus can be easily installed.

  According to the fourth aspect of the invention, since the upper connecting member is an elastic body that also serves as the upper elastic body, the upper connecting member can be formed integrally with the upper elastic body, and the number of parts can be suppressed.

  According to the present invention, when the device is supported on the wall surface, first, the device is supported on the wall surface only by the upper vibration isolating support device, and after the device rotates and stops, the lower vibration isolating support device Support the lower part on the wall. Thus, it is not necessary to perform operations such as obtaining the center of gravity of the device prior to installation of the device. Further, since the upper elastic body extends in the same direction as the shaft member, the upper elastic body does not bend even when the device rotates around the axis of the shaft member. Therefore, it is possible to easily install the device on the wall surface while maintaining the vibration-proof performance of the device support structure.
