Description

[Detailed Description of the Invention] The present invention relates to an improvement of a fixing device for a movable measuring rack on which measuring instruments are mounted and transported.

When storing a mobile measurement rack with casters and a measuring instrument mounted thereon so that it can move freely to the location where measurements are to be taken, in a predetermined location, there is a risk that the measurement rack will move on its own due to an earthquake, etc. In order to prevent this, conventional methods have been to fix the measuring rack using a fixing device. Conventional fixtures of this type, as shown in Utility Model Publication No. 55-8689, connect a pair of left and right fixtures arranged and fixed in accordance with the spacing between the left and right legs of the measuring rack, and the left and right fixtures. By pushing the legs of the measuring rack into the notched recesses formed in the fixed body, the legs are automatically moved into the notched recesses by a locking plate provided inside the fixed body. By operating the operating member, the lock plates of both fixed bodies are released and the legs are released. However, the spacing between the legs of the measuring rack varies depending on the model, so the fixed body is attached so that it can move in the axial direction relative to the operating member so that the distance between the left and right fixed bodies can be adjusted to some extent. Therefore, the mounting structure is complicated, and its adjustment is also time-consuming. Furthermore, there is a limit to the range of adjustment, and in order to meet a wide range of demands, it is necessary to prepare a plurality of types of fixators having operating members of different lengths. In addition, since one end of the operating member is bent to form the operating handle as a single unit, the position of the handle is limited to one direction, either the right or left side, and when arranging the same type of fixation device in one direction. Another disadvantage is that it is necessary to secure space between each fixation device for operating the handle, which makes the installation space inefficient.

The present invention has been developed in view of the above points, and the left and right fixed bodies are provided with operating members individually, and the operating members are removably connected to each other by connecting members of appropriate lengths, thereby making it easy to operate. In addition to ensuring the necessary spacing between the left and right fixed bodies, handles can be detachably attached to the left and right operating members, so that the mounting position of the handles can be changed from left to right as needed. To provide a fixing device for a movable measuring rack that can be used as a stand-alone type that can be operated independently on the left and right sides by attaching handles to both operating members without using any members.

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a plan view showing the internal structure of a fixator embodying the present invention with the top cover removed, and FIG. 2 is a side view thereof. The fixator has a pair of left and right fixing bodies, but since both fixing bodies are bilaterally symmetrical, only the left fixing body is shown in FIGS. 1 and 2. In FIGS. 1 and 2, a fixed body 1 has a bottom plate 2, and the bottom plate 2 is fixed to a fixing fitting such as a square pipe attached to a wall or floor using screws or other means. There is. A U-shaped notch 2a is provided in the bottom plate 2, and an arc-shaped guide piece 3 is fixed to the left edge of the notch 2a to guide the legs of the measuring rack into the notch 2a. Insertion is now smooth. On the bottom plate 2 is a first lock plate 4.
and a second lock plate 5 are each rotatably mounted, and the first lock plate 4 has a recess 4a for locking the leg of the measuring rack therein, and is rotated counterclockwise by a tension spring 6. On the other hand, the second lock plate 5 has a hook portion 5a for locking the first lock plate 4, and is biased counterclockwise by a tension spring 7, so that the first lock plate 4 is inserted into the notched recess. When the opening 2a is closed, the hook 5a engages to lock the first locking plate 4.

Further, a mounting piece 8 is fixed to the bottom plate 2, and an operating member 9 is rotatably inserted into the mounting piece 8 and extending in the left-right direction. An operating hardware 11 that engages with a pusher 10 fixed to the second lock plate 5 is fixed to the operating member 9, and as the operating member 9 rotates, the operating hardware 11 presses the pusher 10 to lock the second lock plate 5. The lock plate 5 is rotated clockwise in FIG. 1 to disengage the hook portion 5a and the first lock plate 4, thereby releasing the first lock plate 4. A return spring 12 is wound around the operating member 9, and exerts a spring force to return the rotated operating member 9 to its original position.

That is, in this fixture, by rotating the operating member 9, the first lock plate 4 is unlocked, and the legs of the measurement rack that are locked in the notch recesses 2a of the fixture 1 are released. It is becoming more and more common.

Further, the operating member 9 has a connecting member attachment portion 9a formed at its right end, and a handle attachment portion 9b at its left end.

Figure 3 is an explanatory diagram of the installation of this fixator.
Figure A shows the case where it is used as an interlocking type, and Figure 3 B shows the case where it is used as an independent type. In FIG. 3A, the left and right fixing bodies 1 are fixed to fixing fittings 14 such as square pipes at intervals corresponding to the spacing between the legs 13 of the measuring rack, and the connecting member 15 is attached to the connecting member mounting portion 9a of the operating member 9. Attach and connect both operating members 9,
Handle mounting portion 9b of operating member 9 of right side fixed body 1
The operating handle 16 is attached to the holder with screws. In this example, the connecting member 15 is made of a pipe and is attached by screwing, but the attachment hole provided in the connecting member 15 is made into an elongated hole that is long in the axial direction, so that the distance between the left and right fixed bodies 1 can be adjusted over a certain range. That's what I do. Further, by preparing the connecting members 15 having different lengths, it is possible to obtain a desired distance between the left and right fixing bodies 1 by replacing the connecting members 15. Then,
By operating the operating handle 16, the left and right operating members 9 connected by the connecting member 15 rotate, and the legs 13 of the measurement frame are released.

In FIG. 3B, the left and right fixing bodies 1 are fixed to the fixing fittings 14 at appropriate intervals, and the operating handles 16 are attached to the handle attachment portions 9b of the left and right operating members 9, respectively, without using the connecting members 15. It is installed so that the left and right sides can be released separately.

That is, in this fixator, if the connecting member 15 is used, it can be used as an interlocking type, or without using the connecting member 15,
By attaching operation handles 16 to both sides, it can be used as a stand-alone type. Furthermore, in the case of interlocking type,
Since the operating handle 16 can be attached to any left or right side, it can be changed as desired depending on the installation location and measurement rack. For example, the fourth
As shown in the figure, when the same type of fixators are arranged in a row, the operation handles 16 are installed alternately on the left and right sides, compared to the conventional case where the handle positions were fixed in one direction. This allows you to save installation space. (Figure 4A shows the present fixator, and Figure 4B shows the conventional fixator.) As described above, according to the present invention, the left and right fixing bodies are individually provided with operating members, and each of the operating members has a handle attachment portion. and a connecting member mounting part for connecting both operating members to each other, so it can be used as an interlocking type or as an independent type, and the mounting position of the operating handle can be easily changed to the left or right, making it easy to use. This is not only convenient, but also advantageous in terms of manufacturing.
