2. Description of the Related Art Conventionally, when mounting a member to be mounted on a base, spacers and washers have been used for the purpose of absorbing variations in the clearance formed between the base and the member to be mounted. . For example, when fixing the cathode ray tube to the main body frame that is the base, a mounting flange for the cathode ray tube,
Depending on the size of the clearance formed between the body frame and the mounting boss, the thickness of the washer and the number of the washers are changed to absorb the variation in the size of the clearance.
The CRT is fixed in place. As such a conventional technique, for example, there is a cathode ray tube mounting device described in Japanese Utility Model Laid-Open No. 62-147971.

However, the work of absorbing the variation in the clearance by adjusting the thickness and the number of the washers and spacers to be arranged has a drawback that it requires a lot of labor and the clearance adjustment range is narrow.

Therefore, as disclosed in Japanese Utility Model Laid-Open No. 1-135875, an adjusting member having a first screw portion and a second screw portion and having a polygonal portion, and the first screw are provided. A cabinet having a third screw part with which the part is screwed, and a fixing screw screwed with the second screw part, and by screwing the fixing screw with the second screw part, A cathode ray tube mounting structure has been proposed in which a mounting flange integrally fixed to the cathode ray tube is sandwiched.

[0005]

However, in the cathode ray tube mounting structure disclosed in Japanese Utility Model Laid-Open No. 1-135875, first, the adjusting member is screwed to some extent in the nut formed in the cabinet to fix the mounting flange. After arranging the cathode ray tube at a predetermined position of the cabinet, through the mounting hole formed in the mounting flange, insert a hexagon wrench or the like into the hexagonal hole formed in the adjusting member, and rotate the adjusting member to move up and down. The adjusting member is brought into contact with the mounting flange. Next, the fixing screw is screwed into the second screw portion of the adjusting member through the mounting hole formed in the mounting flange, thereby fixing the mounting flange to the cabinet and mounting the CRT. For this reason, there is a drawback that the mounting is still troublesome.

An object of the present invention is to solve the above-mentioned conventional problems, and it is possible to simply and easily according to a space formed between a base and a member to be mounted thereon. An object of the present invention is to provide a space adjuster that can adjust height and has a wide adjustment range.

The first sloped surface and the second sloped surface may have a plurality of stepped portions that are formed in a staircase pattern at a pitch of 6 degrees about the central axis of rotation. With this configuration, it is possible to sufficiently oppose the pressing force (compressive load) applied when mounting the mounted member to the base.

Furthermore, in each of the six first inclined surfaces, the start position of the step portion is in phase with the start position of the step portion of the first inclined surfaces adjacent to each other at a predetermined angle. The first inclined surfaces diagonally arranged among the six first inclined surfaces have the same shape, and the second inclined surfaces have the same shape. Can be prepared.

With this structure, the first inclined surface can be surely brought into contact with the second inclined surface oppositely arranged. Therefore, the second gap adjusting member can be more reliably rotated relative to the first gap adjusting member, and the height can be easily adjusted.

Furthermore, the substantially cylindrical convex portion is formed with a slit substantially in the axial direction, and when the second gap adjusting member is rotated relative to the first gap adjusting member. In addition, the diameter can be elastically reduced.

With this structure, the second distance adjusting member can be rotated more reliably and easily relative to the first distance adjusting member.

Further, in the gap adjusting tool according to the present invention, a through hole through which a fixing member for fixing the attached member to the base is formed is formed in the substantially axial center portion of the first engaging portion. However, the fixing member penetrating the through hole may be configured to prevent the reduction of the diameter.

With this structure, when the attached member is fixed to the base by the fixing member, the second gap adjusting member is relatively moved with respect to the first gap adjusting member. Can be prevented from rotating. Therefore, a strong compressive load is applied to the first gap adjusting member and the second gap adjusting member, the first inclined surface and the second inclined surface are surely meshed with each other, and the height of the distance adjusting tool is further shortened. Can be prevented. That is, the space adjusting unit can maintain the optimum height.

The inner peripheral portion of the second gap adjusting member is engageable with the third engaging portion, and is engaged with the third engaging portion, and the first gap adjusting member and the second gap adjusting member are provided. A fourth engaging portion for performing alignment with the distance adjusting member, and by pressing the second distance adjusting member relative to the first distance adjusting member, It is also possible that the engagement with the fourth engagement portion is released and the second spacing adjustment member relatively rotates.

Further, in the first gap adjusting member,
It is also possible to form a fitted portion that fits into the fitting portion formed on the base.

By doing so, the first distance adjusting member can be easily fixed at a predetermined position of the base.

Furthermore, a load receiving surface for receiving a load in the height direction can be provided on a surface of the first gap adjusting member that abuts on the base.

By doing so, for example, when a load in the height direction is applied to the spacing adjuster due to the tightening torque of the fixing screw, the weight of the member to be attached, etc., this force is also received by the load receiving surface. You can

Here, in the state shown in FIGS. 3 and 4, the distance L between the lower surface of the base 12 of the first distance adjusting member 10 and the lower end of the outer peripheral wall of the second distance adjusting member 50 is It is the maximum. The engaging claws 63A and 63B of the second distance adjusting member 50 are in a state of being engaged with the engaging groove 23 of the first distance adjusting member 10. On the other hand, in the state shown in FIG. 5, the lower surface of the base 12 of the first gap adjusting member 10 and the lower end of the outer peripheral wall of the second gap adjusting member 50 coincide with each other, and the distance L is zero. . Therefore, the height of the interval adjusting tool 1 according to the present invention can be adjusted by the distance L.

Next, a specific operation of the gap adjusting tool 1 according to the embodiment of the present invention will be described with reference to the drawings.

First, the gap adjusting tool 1 is set to the initial state as shown in FIGS. In this initial state, as shown in FIG. 15, each inclined portion 19 of the first interval adjusting member 10 is
A, 19B, 19C, 20A, 20B and 20C steps 21A, 21B, 21C, 22A, 22B and 22C
Are inclined portions 59A, 59B of the second gap adjusting member 50,
59C, 60A, 60B and the stepped portions 61A and 61 of 60C
B, 61C, 62A, 62B and 62C are in contact with each other. At this time, the height (height in the vertical direction) of the space adjusting tool 1 is the highest. Further, the engagement claws 63A and 63B of the second interval adjusting member 50 are engaged with the engaging grooves 23 of the first interval adjusting member 10.

Next, the gap adjusting tool 1 in this state is fixed to the boss portions 100 formed at four positions on the cabinet at predetermined positions. That is, as shown in FIGS. 17 and 18, each slit 24A of the gap adjusting tool 1 in this initial state,

The bottom surface of the base 12 contacts the top surface of the boss portion 100. In this way, the first gap adjusting members 10 of the four gap adjusting members 1 are fixed to the boss portion 100, respectively.

Next, the mounting flange 110 for the cathode ray tube.
Is pressed against the gap adjusting tool 1 having the highest height, and a load is applied as shown in FIG. Due to this load, the second spacing adjusting member 50 of each spacing adjusting tool 1
The rotation of the first gap adjusting member 10 in the arrow X direction shown in FIG. 19 starts.

By the rotation of the second gap adjusting member 50, the engaging claws 63A and 63B are moved to the first gap adjusting member 10.
It moves beyond the engaging groove 23 of and is disengaged from both. At the same time, the stepped portions 61A, 61B, 61C, 62A, 62B and 62C of the second gap adjusting member 50 are respectively formed.

In this way, after the distance between the cabinet and the cathode ray tube is appropriately adjusted by the respective spacing adjusters 1, as shown in FIGS. 20 and 21, the insertion hole 18 of the first spacing adjustment member 10 is provided. Then, for example, a fixing member 102 such as a tapping screw is inserted to fix the cabinet and the cathode ray tube.

Here, when the fixing member 102 is inserted into the insertion hole 18, the convex portions 15A, 1A of the first gap adjusting member 10 are inserted.
The elastic deformation of 5B and 15C is prevented, the engaging portions 16A, 16B and 16C and the engaging portion 52 are firmly meshed, and the rotation of the second distance adjusting member 50 is stopped. Therefore, the height of the space adjusting tool 1 can be stably held, and the CRT can be fixed to the cabinet at an optimum position. Further, in this state, even if a high load is applied, the step portions 21A, 21B, 21C, 22A, 22B of the first interval adjusting member 10
And 22C, and the stepped portion 61A of the second gap adjusting member 50,
Since 61B, 61C, 62A, 62B, and 62C mesh with each other, it is possible to prevent the second interval adjusting member 50 from further sinking (rotating).

Therefore, the CRT can be easily and surely attached to the cabinet at a predetermined position regardless of the variation in the gap between the cabinet and the CRT.

In the present embodiment, the case where the first gap adjusting member 10 is provided with six inclined portions and the second gap adjusting member 50 is provided with six inclined portions has been described.
Not limited to this, the inclined portion can be appropriately determined depending on the length (distance) desired to be adjusted, the accuracy of the interval adjustment, the size of the interval adjuster 1, and the like.

In the present embodiment, the steps 21A-2
1C, 22A to 22C and step portions 61A to 61C, 62A
Although the case where the pitch of ~ 62C is set to 6 degrees has been described, the pitch of the stepped portion is not limited to this, and the length (distance) to be adjusted, the accuracy of the interval adjustment, the size of the interval adjuster 1, etc. Can be appropriately determined.

Further, in the present embodiment, in the first gap adjusting member 10, the six inclined portions 19A to 19A are provided.
C, 20A to 20B, the start position of the stepped portion is aligned with the start position of the stepped portion of the adjacent inclined portions at the angle described above, and the diagonally arranged inclined portions have the same shape. However, the angle to be phased is not limited to this, and may be desired depending on the number of inclined portions, the length (distance) to be adjusted, the accuracy of the interval adjustment, the size of the interval adjuster 1, and the like. Can be determined. In addition, the phase does not necessarily have to be set.

Further, in the present embodiment, the case where the cabinet is used as the base and the cathode ray tube is used as the attached member has been described, but the present invention is not limited to this, and the space adjusting tool according to the present invention is installed (arranged). ) The location can be determined appropriately.

[0057]
