Abstract
ABSTRACT
Adjustable tilter device for holding objects such as musical instruments at desired level and position above the floor includes a stationary tilter block de-tachably connected to a standard of a stand and a movable tilter block detachably holding a stem and turnable rel-ative to the stationary tilter block in order for the stem to assume any selected tilting orientation with respect to the stationary tilter. When the stand is used with the stem in the upright state, the stem is kept in axial alignment with the standard so that lateral deviation between the centers of gravity of the two elements should be minimized in order that the stand may support heavy objects in a stable manner and the stem should be accommodated in the standard in a telescopic fashion for convenience in transportation and/or storage of the stand.

Description
lQ~ 9~tS~
BAC~GROUND OF THE INVENTION
The present invention relates to adjustable tilter devices used for holding objects such as musical instruments, and more particularly and specifically relates to an improved construction of an adjustable tilter device for supporting objects such as musical instruments and microphones at desired level and position above the floor and near the player or user.
The conventional stand for holding objects such as musical instruments and microphones generally includes a standard supported at the lower end thereof by adjustable legs via a tripod and a stem turnably coupled atop the standard via a tilter device. The tilter device is of a tubular construction inserted over the stem and adjustably pivoted to the top end of the standard.
When the stem is in an upright disposition with the above-described construction of the stand employing the conventional tilter device, the center axis of the stem is parallel to that of the standard. This parallelism in the center axis results in two fatal drawbacks.
Firstly, the center of gravity of the stem is laterally displaced from that of the standard. Thus, when a relatively heavy object is to be held by the stem, the displacements in the centers of gravity tend to induce easy overturn of the stand with the objects. In other words, the conventional tilter device cannot assure stable support of objects by the stand.
Secondly, when the stand is folded after use, the stem extends parallel to the standard and this parallel arrangement results in relatively bulky folded construction of the entire stand which is quite inconvenient for transpor-tation and storage of same.

DETAILED DESCRIPTION OF THE INVENTION
An example of the conventional tilter device used for musical instruments, such as cymbals and drums, is shown in Figures 1 and 2, in which a stem 1 and a standard 2 are coupled to each other by a connector 3. The stem 1 supports musical instruments at the free end thereof which is not shown in the drawings whereas the standard 2 is carried by a base at the bottom end thereof not shown in the drawing.
The stem 1 is adjustably set to the connector 3 by a set screw 4 and the standard 2 is set to the connector 3 by a set screw 6.

1 ~ 19 ~ 9 When the tilter device is to be used, the standard
2 is placed at a position somewhat removed from the player of the musical instrument, which the tilter device should hold, in order to allow free action of the player, whereas the stem 1 is held in a tilted disposition so that the musical instrument is brought to a position suited for the players preference. This tilted disposition is shown in Figure 1.
When the tilter device is to be folded for transportation or storage, the connector 3 is turned by loosening the set screw 6 until the stem 1 runs parallel with the standard 2 as shown in Figure 2 and the set screw 4 is loosened in order to allow almost the entire length of the stem 1 to be positioned side by side with the standard 2.
In this folded disposition, the bulky parallel arrangement of the two elongated elements 1 and 2 causes a considerable amount of inconvenience in the transportation of the tilter device. In addition, as shown in Figure 2, the central axis A of the stem 1 is not in alignment with the central axis B of the standard 2 in the folded disposition.
This means that, when the tilter device is used with the stem 1 in the upright disposition and supporting a musical instrument, the center of gravity of the mass composed of the stem 1 and the musical instrument carried thereby is laterally displaced from the center of gravity of the standard 2 and its related parts.- This deviation in the centers of gravity leads to unstable support of the musical instrument, especially by the tilter device, when the musical instrument supported by the tilter device is rather heavy, as is the case with cymbals and drums. Thus the conventional tilter is ~` unsuited for supporting heavy musical instruments with the stem 1 in the upright disposition.

1 O~ 1 9 ~`~9 Referring to Figure 3, the adjustable tilter device 100 in accordance with the present invention is used with a stand 7 for supporting a cymbal 8. The stem 1 of the adjustable tilter device 100 carrying the cymbal 8 at its free end is coupled in a tilted disposition to an el-ongated hollow tubular standard 2, the latter member being securely received in an adjustable center post 9 via set screw 11. The degree of extension of the standard 2 from the center post can be freely adjusted and fixed by hand mani-pulation of the set screw 11 in much the same manner as the conventional tilter device. The bottom of center post 9 is supported by a tripod 12 set on the floor by three adjustable legs 13 through lS.
One embodiment of the adjustable tilter device 100 in accordance with the present invention is shown in Figure 4, in which the tilter device 100 is comprised, as the major .
element, of a stationary tilter block 110 and a movable tilter block 150, coupled thereto.
The bottom of stationary tilter block 110 has a collar 111 with a large diameter hole 112 for receiving the upper end portion of the standard 2 and a small diameter hole 113 merging into and in axial alignment with large diameter hole 112. The diameter of the small diameter hole 113 is so designed as to allow free passage of the end portion of the stem 1. The stem 1 is also freely insertable into the upper opening of the hollow tubular standard 2.
The stationary block 110 is further provided with a main body 114 intergrally joined upon the collar 111. A
through-hole 115 is formed in the main body 114 and is aligned to form a right angle with respect to the axes of holes 112 and 113. A pair of annular steps 116 and 117 are formed ~, . :. ~ - . . .

--. lU~1979 ~ncentrically around the through-hole 115 on the side of the main body 114 engageable with the movable tilter block 150. Radial serrations 118 are formed on the main body 114 in an annular arrangement which surrounds step 117 as clearly shown in Figure 5.
The movable block 150 is provided with a through-hole 151 receptive of the stem 1, allowing free passage of the stem 1, and this through-hole 151 is in axial alignment with the holes 11~ and 113 of the stationary tilter block llQ
when both blocks 110 and 150 are coupled to each other as shown in Figure 4. The movable block 150 is further provided with a threaded hole 152 which is alignecl at a right angle with respect to the axis of through-hole 151 and internally terminating in the through-hole 151. The threaded hole 152 is formed so as to be in axial alignment with the through-hole 115 of the stationary tilter block 110 when blocks 110 and 150 are coupled to each other.
On the side facing the stationary tilter block 110, the movable block 150 is provided with an inner cylindrical extension 153 whose outer diameter is slightly smaller than the diameter of the through-hole 115 of the stationary tilter block 110 so that the extension 153 is snugly insertable into the through-hole 115 when blocks 110 and 150 are coupled to each other. ~n outer cylindrical extension is spaced from cylindrical extension 152 to define a hollow annular space 157. The outer diameter of extension 154 is also slightly smaller than the diameter of the inner annular step 116 of the stationary tilter block 110. Thus the extension 154 is snugly fitted within the ` 30 annular step 116 when blocks 110 and 150 are coupled to each ; other. Spacedly surrounding the outer cylindrical extension 1 0~ 19~
154. An annular arrangement of serrations 155 are spaced from and surround extension 154 as is clearly shown in Figure 6. The position and pattern of the radial serrations 155 on the movable tilter block 150 are designed to fairly correspond to the radial serrations 118 on the stationary tilter block 110. The inner cylindrical extension 153 of the movable tilter block 150 has a threaded hole 156 which is formed so as to be in axial alignment with the axis of threaded hole 152 and internally terminates in the through-hole lSl.
In the disposition shown in Figure 4 in which the tilter blocks 110 and 150 are coupled to each other, a helical compression spring 158 is inserted in the annular space 157 around the inner cylindrical extension 113 of the movable tilter block 150, a set screw 159 is screwed into the threaded hole 156 of the inner cylindrical extension 153 in order to securely couple the stationary tilter block 110 to the movable tilter block lS0 via an accompanying washer 161 against the force of compression spring 158 and another set screw 162 is screwed into the threaded hole 152 of the movable tilter block lS0 in such an arrangement that the inner end of the set screw 162 presses the stem 1 against the wall of the block lS0 defining the hole lSl in order to prevent free passage of the stem 1 into the hole lSl When so assembled, the serrations 118 on the stationary tilter block 110 are in meshing engagement with the serrations 155 on the movable tilter block 150, the ' outer cylindrical extension 154 of the movable tilter block ; lS0 is snugly received within the annular step 116 of the stationary tilter block 110 while leaving a small space 119 . between the free end of the extension 154 and the stationary . 8 , ,. .. . . .... .. . . .. . . . -1C~1 9'-~block 110 and the inner cylindrical extension 153 of the movable tilter block 150 is snugly accommodated within the through-hole 115 of the stationary tilter block 110. The stationary tilter block 110 may be fixed to the standard 2 by a suitable set screw (not shown).
In the disposition shown in Figure 4, the stem 1 is held in the upright state and the center line of the stem 1 is in axial alignment with that of the standard 2 so that ~here is no lateral displacement between the centers of gravity of the two elements 1 and 2. When this disposition is compared with that shown in Figure 2, it will be well understood that the stand using the tilter 100 in accordance with the present invention is by far more stable than the stand accompanied with the conventional connector 3 with the stem 1 being used in the upright state in order to support musical instruments or the like of relatively large weight.
When the stand is to be folded for the purpose of transportation or storage, the set screw 162 in Figure 4 is loosened for liberation of the stem 1 and the stem 1 is inserted into the standard 2. Thus, folding of the stand can be completed in telescopic manner and this assures a very compact folded construction of the stand which is very convenient for transportation and storage.
When the stand 7 is to be used with the stem 1 being in a tilted disposition, the set screw 162 is loosened, the stem 1 is withdrawn from the standard 2 until the lower end is positioned at least at the level of the bottom end of the movable tilter block 150 and the set screw 162 is provisionally refastened. Thus, the stem 1 is fixed to the movable tilter block 150 only irrespective of the stationary tilter block 110.

Next, the other set screw lS9 is loosened some-what to such an extent that the serrations 118 are dis-placed from meshing engagement with the serrations 155 due to the force of compression spring 158 in the annular space 157 acting to separate the two blocks. Use of the compression spring 158 on one hand greatly facilitates the release of the aforesaid meshing engagement and, on the other hand, prevents acciden~al loosening of the set screw 159 during the use of the stand 7.
With the release of the aforesaid meshing engage-ment, the movable tilter block 150 is now freely turnable about the center axis of its threaded hole relative to the stationary tilter block 110.
After turning the movable tilter block 150 over a desired center angle in the above-described sense to-gether with the stem 1 fixedly held thereby, the set screw 159 is refastened in order to restore the meshing engagement between serrations 118 and 155 and the fixed coupling between the tilter blocks 110 and lS0. Use of the compression spring 158 greatly facilitates movement of the movable tilter block 150 relative to the stationary tilter block 110 as the force of the spring 158 keeps the serrations 118 dis-placed from the serrations throughout the procedure.
Finally, the set screw 162 is again loosened in order to adjust the length of the portion of the stem 1 ex-tending from the tilter 100. After all the operations are j completed, the stem 1 assumes a tilted dispostion such as shown in Figure 7.
In order to fold the stand 7 from the disposition . 30 shown in Figure 7, the above-described operations are ~`
9~,5' performed in the substantially reverse order.
As is clear from the foregoing description, use of ~he tilter in accordance with the present invention assures enhanced stability of the stend even when supporting heavy objects, a remarkably compact folded construction of the stand specially convenient for transportation and/or storage and easy adjustment of the tilting direction of the stem in accordance with the situation in which the stand is to be used.
When the tilter device is to be folded for transportation or storage, the connector 3 is turned by loosening the set screw 6 until the stem 1 runs parallel with the standard 2 as shown in Figure 2 and the set screw 4 is loosened in order to allow almost the entire length of the stem 1 to be positioned side by side with the standard 2.
In this folded disposition, the bulky parallel arrangement of the two elongated elements 1 and 2 causes a considerable amount of inconvenience in the transportation of the tilter device. In addition, as shown in Figure 2, the central axis A of the stem 1 is not in alignment with the central axis B of the standard 2 in the folded disposition.
This means that, when the tilter device is used with the stem 1 in the upright disposition and supporting a musical instrument, the center of gravity of the mass composed of the stem 1 and the musical instrument carried thereby is laterally displaced from the center of gravity of the standard 2 and its related parts.- This deviation in the centers of gravity leads to unstable support of the musical instrument, especially by the tilter device, when the musical instrument supported by the tilter device is rather heavy, as is the case with cymbals and drums. Thus the conventional tilter is ~` unsuited for supporting heavy musical instruments with the stem 1 in the upright disposition.

1 O~ 1 9 ~`~9 Referring to Figure 3, the adjustable tilter device 100 in accordance with the present invention is used with a stand 7 for supporting a cymbal 8. The stem 1 of the adjustable tilter device 100 carrying the cymbal 8 at its free end is coupled in a tilted disposition to an el-ongated hollow tubular standard 2, the latter member being securely received in an adjustable center post 9 via set screw 11. The degree of extension of the standard 2 from the center post can be freely adjusted and fixed by hand mani-pulation of the set screw 11 in much the same manner as the conventional tilter device. The bottom of center post 9 is supported by a tripod 12 set on the floor by three adjustable legs 13 through lS.
One embodiment of the adjustable tilter device 100 in accordance with the present invention is shown in Figure 4, in which the tilter device 100 is comprised, as the major .
element, of a stationary tilter block 110 and a movable tilter block 150, coupled thereto.
The bottom of stationary tilter block 110 has a collar 111 with a large diameter hole 112 for receiving the upper end portion of the standard 2 and a small diameter hole 113 merging into and in axial alignment with large diameter hole 112. The diameter of the small diameter hole 113 is so designed as to allow free passage of the end portion of the stem 1. The stem 1 is also freely insertable into the upper opening of the hollow tubular standard 2.
The stationary block 110 is further provided with a main body 114 intergrally joined upon the collar 111. A
through-hole 115 is formed in the main body 114 and is aligned to form a right angle with respect to the axes of holes 112 and 113. A pair of annular steps 116 and 117 are formed ~, . :. ~ - . . .

The movable block 150 is provided with a through-hole 151 receptive of the stem 1, allowing free passage of the stem 1, and this through-hole 151 is in axial alignment with the holes 11~ and 113 of the stationary tilter block llQ
when both blocks 110 and 150 are coupled to each other as shown in Figure 4. The movable block 150 is further provided with a threaded hole 152 which is alignecl at a right angle with respect to the axis of through-hole 151 and internally terminating in the through-hole 151. The threaded hole 152 is formed so as to be in axial alignment with the through-hole 115 of the stationary tilter block 110 when blocks 110 and 150 are coupled to each other.

The outer diameter of extension 154 is also slightly smaller than the diameter of the inner annular step 116 of the stationary tilter block 110. Thus the extension 154 is snugly fitted within the ` 30 annular step 116 when blocks 110 and 150 are coupled to each ; other. Spacedly surrounding the outer cylindrical extension 1 0~ 19~

The position and pattern of the radial serrations 155 on the movable tilter block 150 are designed to fairly correspond to the radial serrations 118 on the stationary tilter block 110. The inner cylindrical extension 153 of the movable tilter block 150 has a threaded hole 156 which is formed so as to be in axial alignment with the axis of threaded hole 152 and internally terminates in the through-hole lSl.
In the disposition shown in Figure 4 in which the tilter blocks 110 and 150 are coupled to each other, a helical compression spring 158 is inserted in the annular space 157 around the inner cylindrical extension 113 of the movable tilter block 150, a set screw 159 is screwed into the threaded hole 156 of the inner cylindrical extension 153 in order to securely couple the stationary tilter block 110 to the movable tilter block lS0 via an accompanying washer 161 against the force of compression spring 158 and another set screw 162 is screwed into the threaded hole 152 of the movable tilter block lS0 in such an arrangement that the inner end of the set screw 162 presses the stem 1 against the wall of the block lS0 defining the hole lSl in order to prevent free passage of the stem 1 into the hole lSl When so assembled, the serrations 118 on the stationary tilter block 110 are in meshing engagement with the serrations 155 on the movable tilter block 150, the ' outer cylindrical extension 154 of the movable tilter block ; lS0 is snugly received within the annular step 116 of the stationary tilter block 110 while leaving a small space 119 . between the free end of the extension 154 and the stationary . 8 , ,. .. . . .... .. . . .. . . . -1C~1 9'-~block 110 and the inner cylindrical extension 153 of the movable tilter block 150 is snugly accommodated within the through-hole 115 of the stationary tilter block 110. The stationary tilter block 110 may be fixed to the standard 2 by a suitable set screw (not shown).
In the disposition shown in Figure 4, the stem 1 is held in the upright state and the center line of the stem 1 is in axial alignment with that of the standard 2 so that ~here is no lateral displacement between the centers of gravity of the two elements 1 and 2. When this disposition is compared with that shown in Figure 2, it will be well understood that the stand using the tilter 100 in accordance with the present invention is by far more stable than the stand accompanied with the conventional connector 3 with the stem 1 being used in the upright state in order to support musical instruments or the like of relatively large weight.

Thus, folding of the stand can be completed in telescopic manner and this assures a very compact folded construction of the stand which is very convenient for transportation and storage.
When the stand 7 is to be used with the stem 1 being in a tilted disposition, the set screw 162 is loosened, the stem 1 is withdrawn from the standard 2 until the lower end is positioned at least at the level of the bottom end of the movable tilter block 150 and the set screw 162 is provisionally refastened. Thus, the stem 1 is fixed to the movable tilter block 150 only irrespective of the stationary tilter block 110.

Next, the other set screw lS9 is loosened some-what to such an extent that the serrations 118 are dis-placed from meshing engagement with the serrations 155 due to the force of compression spring 158 in the annular space 157 acting to separate the two blocks. Use of the compression spring 158 on one hand greatly facilitates the release of the aforesaid meshing engagement and, on the other hand, prevents acciden~al loosening of the set screw 159 during the use of the stand 7.
With the release of the aforesaid meshing engage-ment, the movable tilter block 150 is now freely turnable about the center axis of its threaded hole relative to the stationary tilter block 110.
After turning the movable tilter block 150 over a desired center angle in the above-described sense to-gether with the stem 1 fixedly held thereby, the set screw 159 is refastened in order to restore the meshing engagement between serrations 118 and 155 and the fixed coupling between the tilter blocks 110 and lS0.
