Abstract

PROBLEM TO BE SOLVED: To make it easy to mount and dismount a cuff to and from a main body despite mounting using hooks. SOLUTION: In the sphygmomanometer, a cuff is mounted to the main body and integrated therewith. A plurality of hooks 21a to 21c that are projected from the cuff side are made available in two kinds whose head projections projected from the cuff side are turned in nearly perpendicular directions. The tightening direction of a screw 15 in the portion where the cuff side and the main body portion are screwed together is almost the same as the head projection of one hook 21c. The elimination of hooks whose head projections are turned in opposite directions helps prevent the hooks from pushing each other and the tightening of the screw 15 in the screwing portion helps the hook 21c whose head projection is turned in the tightening direction to be hooked onto the main body side.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a sphygmomanometer in which a main body and a cuff band are integrated.

[0002]

2. Description of the Related Art In a sphygmomanometer in which a main body is attached to a cuff band, as shown in FIG. 5, a plurality of hooks 21 project from a synthetic resin connecting plate 20 incorporated in the cuff band 2. A lock hole 12 into which the hook 21 is inserted and locked is provided on the case 10 side of the main body 1, and the hook 21 is passed through the lock hole 12 and locked to a hole edge of the lock hole 12. The body is attached to the cuff belt with.

At this time, in order to eliminate backlash between the cuff band and the main body, a pair of hooks 21 (two pairs in the illustrated example) are provided in which the directions of the tip projections are opposite to each other.

[0004]

In this case, when it becomes necessary to remove the main body from the cuff band, the hooks 21 are unlocked because the pair of hooks 21 are engaged so as to project from each other. Is difficult, especially when the hook 21
It is even more difficult with the illustrated example. As shown in FIG. 5, instead of one hook 21, a fixing piece 22 for screwing is used.
And the fixing piece 22 is inserted into the case 1 through the insertion hole 13.
In the case where the hook 21 is inserted into the hole 0 and fixed to the receiving seat 14 with the screw 15, only one pair of hooks 21 are in contact with each other.
Although it is easier to remove than the conventional example described above, it is still difficult to release the hook 21.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object the sphygmomanometer in which the main body can be easily attached to and detached from the cuff band despite attachment using a hook. To provide.

[0006]

According to the present invention, there is provided a sphygmomanometer in which a main body is attached to a cuff band and the two are integrated, and a plurality of hooks protruding from the cuff band side are engaged with a tip projection for locking. Are oriented in directions substantially orthogonal to each other, and the direction of tightening of the screw at the screw fixing portion between the cuff side and the main body is substantially the same as the direction of the tip projection of one of the two types of hooks. It is characterized by the direction. Eliminating the hooks with the tip protrusions facing in opposite directions eliminates the state in which the hooks are in contact with each other.Furthermore, by tightening the screws of the screw fixing part, the hooks with the tip protrusions facing in the tightening direction are engaged with the main body side. It is intended to be stopped.

It is preferable that the screw fixing portion and the hook whose tip is directed in the screw tightening direction of the screw fixing portion are arranged on a straight line in the screw tightening direction.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of an embodiment of the present invention will be described. The sphygmomanometer shown in FIG. 3 is of a type to be attached to a wrist, and has an arc-shaped cross section for easy attachment to a wrist. The main body 1 is attached to the outer surface of the cuff band 2 containing the formed synthetic resin connecting plate 20 by locking with a hook 21 protruding from the connecting plate 20 and screwing a fixing piece 22. I have.

The main body 1 having a display portion 37 made of a liquid crystal display on the front side has a built-in pump 31, a power supply 30, and the like.
It is arranged before and after zero. In the figure, reference numeral 11 denotes a battery case. Here, as shown in FIG. 1, three hooks 21 (21a, 21a,
21b, 21c) and one fixing piece 22 are projected, and the three hooks 21a,
Three locking holes 12 corresponding to 21b and 21c, an insertion hole 13 through which the fixing piece 22 is inserted, and a receiving seat 14 for screwing the fixing piece 22 are provided.
Two of the hooks 21a and 21b are formed so that the tip projections are directed in the same direction, and the other one hook 21c is one in which the tip projections are oriented in directions different from the two hooks 21a and 21b by 90 °. The direction in which the fixing piece 22 is fixed to the receiving seat 14 by the screw 15 (the direction F in FIG. 2) is set to the direction in which the one hook 21c is locked in the locking hole 12. I have.

Therefore, the fixing piece 22 is fixed to the seat 14 with the screw 15.
In the state where the three hooks 21a, 2
1b and 21c both keep a state in which they are deeply locked at the edge of the locking hole 12, so that the connecting plate 20 and the case 1
There is no rattling between zero. However, if the screw 15 is removed, the force in the F direction does not work,
Since the one hook 21c can be separated from the hole edge of the locking hole 12 as shown in FIG. 2 (b), the fixing piece 22 and the one hook 21c can be inserted into the insertion hole 13 and the locking hole 1 respectively.
2, and the two hooks 21a and 21b remaining therefrom can be easily removed from the locked state with the locking hole 12.

To fix the case 10 to the connecting plate 20,
First, the two hooks 21a and 21b facing in the same direction are inserted into the locking holes 12, respectively, and the hooks 21c are left by rotating the connecting plate 20 with respect to the case 10 around these portions.
Into the locking hole 12 and the fixing piece 22 into the insertion hole 1.
3, the hooks 21 a and 21 b are locked to the edge of the locking hole 12. Further, when the fixing piece 22 is fastened to the receiving seat 14 by the screw 15, the hook 21 c is Lock to the hole edge.

The hook 21c whose tip protrusion is directed in the direction of tightening by the screw 15 should be located on a straight line when viewed from the screw 15, so that the tightening force can be reliably used as the locking force of the hook 21. It is preferable to work. The screw 15 is exposed to the outside when the battery cover 11 is removed from the case 10 of the main body 1. Therefore, the work of assembling and removing the main body 1 from the cuff band 2 can be easily performed by removing the battery cover 11.

[0013]

As described above, according to the present invention, a plurality of hooks projecting from the cuff band side are of two types in which the tip projections for locking are oriented in a direction substantially orthogonal to each other. In addition to the above, the direction of tightening the screw in the screw fixing portion between the cuff side and the main body is almost the same as the direction of the tip projection of one of the two types of hooks, By tightening the screw of the fixing part, the hook whose tip projection is directed in the tightening direction is locked to the main body side, so that it is possible to perform a rattling-free fixing and at the same time loosen the screw It can be easily removed only by itself.

If the screw fixing portion and the hook whose tip protrudes in the screw tightening direction of the screw fixing portion are arranged on a straight line in the screw tightening direction, more secure fixing can be achieved. Can be.
