It will be apparent that embodiments of the present application may be practiced without limitation to the specific details that are set forth by those skilled in the art. Preferred embodiments of the present application are described in detail below, however, the present application may have other embodiments in addition to these detailed descriptions.

First embodiment

The application provides a container. The container can be used for transporting bulk cargo. The container has a bottom opening 111, the bottom opening 111 being used for discharging bulk goods.

Referring to fig. 1 to 7, the container includes a case 110. The case 110 has a substantially rectangular parallelepiped structure. The top end of the case 110 has a top opening. Bulk cargo may be loaded into the bin 110 via the top opening. The container also includes a top cover. The top cover is removably attached to the top end of the case 110 for opening or closing the top opening. Neither the end wall nor the side wall of the cabinet 110 is provided with a cabinet door. The corners of the case 110 are provided with reinforcing members (not shown) connecting the end walls and the side walls to reinforce the connection strength of the end walls and the side walls.

It will be appreciated that in an embodiment not shown, the container may not be provided with a roof. The container then comprises tarpaulin. The tarpaulin is used for covering the top opening.

As shown in fig. 1 to 5, the bottom end of the case 110 is provided with a bottom opening 111. The housing 110 also includes a bottom door 120. One end of the bottom door 120 is pivotally connected to an end of the bottom end of the case 110 in the width direction of the case 110. In this way, the bottom door 120 can be rotated between an open position to open the bottom opening 111 and a closed position to close the bottom opening 111. With the bottom door 120 in the open position, bulk cargo within the bin 110 may be discharged through the bottom opening 111. The end of the bottom door 120 in the longitudinal direction of the case 110 is provided with a hooking portion 121.

It will be appreciated that in an embodiment not shown, the bottom door may also be pivotally connected to the bottom end of the case at a substantially intermediate position in the width direction of the case.

The container further comprises a first slider 130. The first slider 130 is connected to an end of the case 110 in the length direction of the case 110. The first slider 130 is movably disposed in the height direction of the case 110. In this way, the first slider 130 can move between the slide-lock position and the slide-unlock position in the height direction of the case 110.

The container also includes a connector 164. The connector 164 may be a rod. The connection member 164 is located below the first slider 130 and is connected to the first slider 130. The container also includes a linkage assembly 140. The link assembly 140 includes a first link 141 and a second link 142. The first and second connection bars 141 and 142 are inclined to the height direction of the case 110. The first end of the first connecting rod 141 is pivotally connected to the connecting member 164 and is further connected to the first slider 130 through the connecting member 164. The first end of the second connecting rod 142 is connected to the first connecting rod 141. The second connection rod 142 is movable with respect to the first connection rod 141 between a short connection position and a long connection position along the length direction of the first connection rod 141. Thus, the structure of the case 110 is simple.

In the case where the second connecting rod 142 is located at the short connecting position, the size of the connecting rod assembly 140 is the short connecting size along the length direction of the first connecting rod 141. When the second connecting rod 142 is located at the long connecting position, the dimension of the connecting rod assembly 140 is the long connecting dimension along the length direction of the first connecting rod 141. The short connection dimension is smaller than the long connection dimension. That is, the first end of the second connecting rod 142 is closer to the first end of the first connecting rod 141 at the short connecting position than at the long connecting position of the second connecting rod 142. In the case where the second link 142 is located at the long connection position, the first end of the second link 142 is located at the end of the long hole 143 that is far from the first end of the first link 141. A second end of the second connecting lever 142 is pivotally connected to the bottom door 120 by an adjustment assembly 144, which will be described later.

With continued reference to fig. 1-5, the container further includes a shackle 150. Latch hook 150 is pivotally connected to housing 110. So that the latch hook 150 can be rotated between a hooked position and an unhooked position. With the bottom door 120 in the closed position, the latch hook 150 in the hooked position can be hooked to the hooking portion 121, thereby locking the bottom door 120 in the closed position. With the latch hook 150 in the unhooked position, the latch hook 150 is clear of the hook joint 121. At this time, the bottom door 120 can be rotated.

The connector 164 is pivotally connected to the shackle 150. In this way, the first slider 130 moving in the height direction of the case 110 can rotate the latch hook 150 via the connector 164. As such, the first slider 130, the latch hook 150, and the link assembly 140 are coupled.

Specifically, as shown in fig. 1, in the case where the first slider 130 is located at the sliding locking position, the bottom door 120 is located at the closing position, the second connecting rod 142 is located at the long connecting position, and the latch hook 150 is located at the hooking position. As shown in fig. 1 and 2, if it is desired to discharge the bulk cargo within the case 110, the first slider 130 is moved downward from the slide-lock position to the slide-unlock position. In the process that the first slider 130 moves downwards from the sliding locking position to the sliding unlocking position, the first slider 130 drives the first connecting rod 141 to move relative to the second connecting rod 142, so that the second connecting rod 142 moves towards the short connecting position relative to the first connecting rod 141. In the process that the first sliding member 130 moves downwards from the sliding locking position to the sliding unlocking position, the first sliding member 130 drives the latch hook 150 to rotate from the hooking position to the unhooking position.

As shown in fig. 2 and 3, with the first slider 130 in the slide unlock position, the latch hook 150 is in the unlatch position to unlock the bottom door 120. With the first slider 130 in the slide unlock position, the second connecting rod 142 is in the short connecting position. At this time, the bottom door 120 automatically turns downward by gravity and the goods in the case 110, thereby being rotated from the closed position to the open position. During the inversion of the bottom door 120, the second connection rod 142 moves relative to the first connection rod 141 to move from the short connection position to the long connection position.

As shown in fig. 1, 4 and 5, after the bulk cargo in the case 110 is discharged, if the bottom door 120 is required to close the bottom opening 111, the first slider 130 is moved upward from the slide-unlock position to the slide-lock position. In the process that the first sliding member 130 moves upwards from the sliding unlocking position to the sliding locking position, the first sliding member 130 drives the latch hook 150 to rotate from the unhooking position to the hooking position through the connecting member 164, and simultaneously drives the bottom door 120 to rotate from the opening position to the closing position through the connecting rod assembly 140. As shown in fig. 1, when the bottom door 120 is rotated to the closed position, the latch hook 150 rotated to the latched position is hooked to the hooking portion 121 of the bottom door 120.

In this embodiment, the first slider 130 and the latch hook 150 are linked with the link assembly 140, and in the process that the first slider 130 moves between the sliding locking position and the sliding unlocking position, the link assembly 140 and the latch hook 150 are driven to move, so that the bottom door 120 rotates between the opening position and the closing position, and the bottom door 120 of the container can be opened by operating the first slider 130, so that the operation of opening the bottom door 120 of the container is simple, the bulk cargo in the container 110 does not need to be discharged by turning the container 110 by a lifting appliance, and the operation of discharging the bulk cargo in the container 110 is simple and safe.

Preferably, referring to fig. 1 to 5, the first connecting rod 141 is provided with a long hole 143. The long axis of the long hole 143 is parallel to the length direction of the first connecting rod 141. The first end of the second connection rod 142 is connected to the first connection rod 141 through the long hole 143. In this way, the first end of the second connecting rod 142 can move within the long hole 143 in the long axis direction of the long hole 143, thereby enabling the second connecting rod 142 to move between the long connection position and the short connection position. Thus, the link assembly 140 has a simple structure.

It will be appreciated that in an embodiment not shown, a long hole may also be provided in the second connecting rod. At this time, the second end of the first connecting rod is connected to the second connecting rod through the long hole.

It will be appreciated that in embodiments not shown, the linkage assembly may also be configured as a telescopic tube structure in which the first connecting rod is sleeved over the second connecting rod.

Preferably, referring to fig. 1 to 5, the latch hook 150 includes a hook body 151, a hook head 152, a first pivot portion 153 and a second pivot portion 154. The hook head 152, the first pivot 153 and the second pivot 154 are all located on the same side of the hook body 151. The hook head 152, the first pivot 153 and the second pivot 154 are all connected to the hook body 151. The hook head 152, the first pivoting portion 153 and the second pivoting portion 154 are disposed at intervals along the height direction of the case 110. The first pivot portion 153 is pivotally connected to the case 110, the second pivot portion 154 is connected to the first slider 130 through the connecting member 164, and the hook portion 152 is configured to be hooked to the hook portion 121. In this way, the latch hook 150 has a simple structure.

The lower end of the hook head 152 has a hook guide ramp 155. The latch hook guide slope 155 is inclined to the height direction of the latch hook 150. In the case where the latch hook 150 is hooked to the hooking part 121, the height direction of the latch hook 150 is substantially parallel to the height direction of the case 110. During the movement of the first slider 130 from the slide unlock position to the slide lock position, the hooking portion 121 abuts against the hook guide slope 155 to slide along the hook guide slope 155, thereby hooking the hook 150 to the hooking portion 121. Thereby, the hook head 152 can be hooked to the hooking portion 121 more conveniently.

Further preferably, the shackle 150 is configured in a generally F-shaped configuration. Thus, the structure of the latch hook 150 is simpler.

As shown in fig. 1-5, the container also includes a pivot 160. One end of the pivoting member 160 is pivotally connected to the second pivoting portion 154 of the latch hook 150. The other end of the pivoting member 160 is pivotally connected to the connecting member 164 and thus to the first slider 130. Thus, the first slider 130 needs to be moved downward a longer distance to enable the latch hook 150 in the hooked position to rotate to the unhooked position. In this way, the bottom door 120 can be opened at a greater angle.

Preferably, the pivoting member 160 is an elastic member. In this way, the pivot 160 can flex and recover after flexing. For example, pivot 160 may be a cylindrical spring. In this way, when the hooking portion 121 and the latch hook 150 interfere to prevent the bottom door from being normally closed, the pivot 160 can be bent, so that the latch hook 150 can be hooked to the hooking portion 121. In addition, the pivot member 160 is an elastic member, and the first sliding member 130 can further move downward for a longer distance when the latch hook 150 rotates to the unlatched position. In this way, the bottom door 120 can be opened at a greater angle.

It will be appreciated that in an embodiment not shown, a shackle actuation assembly may also be provided for actuating the rotation of the shackle. At this time, the latch hook and the link assembly are not linked.

Preferably, as shown in fig. 1 to 5, the container further comprises a first rail 163. The length direction of the first guide rail 163 extends in the height direction of the case 110. The first guide rail 163 is connected to the case 110. The first slider 130 is connected to the first guide rail 163. The first slider 130 and the first guide rail 163 cooperate to guide movement of the first slider 130 in the height direction of the case 110. Thereby, the movement of the first slider 130 in the height direction of the case 110 is more stable.

Preferably, the container further comprises a second slider 190 and a second rail. The second slider 190 is positioned below the first slider 130. The second slider 190 is movably coupled to the case 110 in the height direction thereof. The length direction of the second guide rail extends along the height direction of the box body. The second slider 190 is connected to the second rail. The second slider 190 and the second guide rail cooperate to guide movement of the second slider 190 in the height direction of the case. The connector 164 is connected to the second slider 190. The second slider 190 is pivotally connected to the pivot 160. Thus, when the first sliding member 130 moves along the height direction of the case 110, the first sliding member 130 drives the latch hook 150 to rotate through the connecting member 164, the second sliding member 190 and the pivoting member 160. Thus, the structure of the case 110 is simple.

It is further preferable that the cross section of the first guide rail 163 (the cross section is perpendicular to the height direction of the case 110) is in a T-shaped structure. Thereby facilitating the selection of the first guide rail 163. It will be appreciated that in an embodiment not shown, the first rail may be a planar rail.

Preferably, referring to fig. 1-5, the linkage assembly 140 further includes an adjustment assembly 144. The length of the adjustment assembly 144 is adjustable. The second end of the second connecting rod 142 is connected to one end of the adjustment assembly 144. The other end of the adjustment assembly 144 is pivotally connected to the bottom door 120. The adjustment assembly 144 may be a prior art adjustment rod, and is not described in detail herein. Thus, the length of the adjustment assembly 144, and thus the length of the link assembly 140, may be adjusted as needed, thereby increasing the angle at which the bottom door 120 can be opened.

It will be appreciated that in an embodiment not shown, the first and second connecting rods are adjustable in length. So, can adjust the length of head rod and second connecting rod as required, and then the angle that the adjustment bottom door can be opened.

Preferably, the container further comprises a buffer assembly (not shown). The cushioning assembly may be a tension spring, a compression spring or an air spring. The buffer assembly is coupled to one of the bottom door 120 and the case 110. When the bottom door 120 rotates, the buffer assembly can slow down the rotation speed of the bottom door 120.

Preferably, the bottom doors 120 are two. The two bottom doors 120 form a side-by-side door system. The number of the latch hooks 150 and the connecting rod assemblies 140 is two. The two latch hooks 150 are disposed in one-to-one correspondence with the two bottom doors 120. The two link assemblies 140 are disposed in one-to-one correspondence with the two bottom doors 120. The bottom door 120 connects the link assembly 140 and the latch hook 150 corresponding thereto.

Preferably, none of the first slider 130, the connector 164, the link assembly 140, the pivot 160, the latch hook 150, the later latch 165, and the later latch spring 166 protrude beyond the contour of the case 110. Thereby facilitating transportation of the container.

Preferably, the container also includes a seal 168. The seal 168 may be a rubber seal. Seal 168 is connected to one of the tank 110 and bottom door 120. With the bottom door 120 in the closed position, the bottom door 120 compresses the seal 168 against the housing 110 to seal the gap between the bottom door 120 and the housing 110.

Preferably, with continued reference to fig. 1-5, the container further includes an adjustment stop assembly 169. The adjustment limit assembly 169 is connected to the chassis of the case 110. With the bottom door 120 in the closed position, the adjustment limit assembly 169 can act on the bottom door 120 to compress the bottom door 120 to the housing 110. Specifically, the adjustment limit assembly 169 includes a press and a bolt. The bolt passes through the pressing piece. The bolts are screwed to the bottom chassis of the case 110. With the bottom door 120 in the closed position, the follower may be positioned below the free end of the bottom door 120. At this time, the pressing member presses the free end of the bottom door 120 to the bottom chassis by tightening the bolts.

With the bottom door 120 in the open position, the floor covering is located above or flush with the lower surface of the chassis. Thus, the floor mopping protection portion can increase the strength of the bottom door 120, preventing the bottom door 120 from being deformed. In addition, the floor mopping protection part can prevent the bottom door 120 from mopping, thereby protecting the bottom door 120.

Referring to fig. 1 to 7, the present embodiment further provides a lifting appliance. The first slider 130 is provided with an operating portion 131 for connection with a spreader. As shown in fig. 6 and 7, the spreader includes a spreader body 170. The spreader body 170 may be substantially identical to the body of a spreader currently used to hoist containers. And will not be described in detail here. The spreader also includes a drive assembly. The drive assembly includes a first drive assembly 171 and a second drive assembly 172.

The first driving assembly 171 may be a driving cylinder. The cylinder of the first driving assembly 171 is pivotally connected to one end of the spreader body 170 in the length direction of the spreader. When the lifting appliance lifts the container, the length direction of the lifting appliance is parallel to the length direction of the box body, the width direction of the lifting appliance is parallel to the width direction of the box body, and the height direction of the lifting appliance is parallel to the height direction of the box body.

The head of the first driving assembly 171 is disposed at the free end of the cylinder shaft of the first driving assembly 171. Thus, the head of the first driving assembly 171 is movably disposed along the length direction of the first driving assembly 171.

The second drive assembly 172 may be a drive ram. The cylinder of the second driving assembly 172 is connected to one end of the spreader body 170 in the length direction of the spreader. The second drive assembly 172 is located above the spreader body 170. The length of the second drive assembly 172 is parallel to the length of the spreader.

It will be appreciated that in an embodiment not shown, the second drive assembly may also be a lead screw nut arrangement.

With continued reference to fig. 6 and 7, the head of the second drive assembly 172 is disposed at the free end of the piston shaft of the second drive assembly 172. Thus, the head of the second drive assembly 172 is movably disposed along the length of the second drive assembly 172. The head of the second drive assembly 172 is pivotally connected to the cylinder of the first drive assembly 171. Along the length of the first drive assembly 171, there is a gap between the head of the second drive assembly 172 and the pivot location of the first drive assembly 171 and the spreader body 170.

The second drive assembly 172 is capable of driving the first drive assembly 171 between a disengaged position (the position of the first drive assembly 171 shown in solid lines in fig. 6 and 7) and a connected position (the position of the first drive assembly 171 shown in phantom lines in fig. 6 and 7). With the first drive assembly 171 in the off position, the head of the first drive assembly 171 is clear of the first slider 130. With the first driving assembly 171 located at the connection position, the head of the first driving assembly 171 can be connected to the operating part 131 of the first slider 130. In the case where the first driving assembly 171 is located at the connection position, the length direction of the first driving assembly 171 is parallel to the height direction of the case 110. In this way, the first driving assembly 171 can be used to drive the first slider 130 to move in the height direction of the case 110.

As shown in fig. 6 and 7, the container transporting bulk cargo is moved to the spreader. At this time, the first slider 130 is located at the sliding locking position, the bottom door 120 is located at the closing position, and the latch hook 150 is located at the hooking position. The hanger can be connected to the upper end of the case 110. At this time, the second driving component 172 drives the first driving component 171 to rotate to the connection position, so that the head of the first driving component 171 moves to the operation portion 131 of the first slider 130, and is further connected to the operation portion 131. In this way, the first driving assembly 171 can drive the first sliding member 130 to move along the height direction of the case 110, so that the latch hook 150 rotates to the unhooking position, and the bottom door 120 can be automatically opened.

In this embodiment, the first slider 130 may be driven to move along the height direction of the box 110 by the operation portion 131 connected to the first slider 130 through the lifting tool, so that the bottom door 120 may be opened, the operation of opening the bottom door 120 is simple, the box 110 does not need to be turned over by the lifting tool to discharge bulk cargo in the box 110, and the operation of discharging bulk cargo in the box 110 is simple and safe.

Preferably, the head of the first driving assembly 171 may be a connection hook.

It will be appreciated that in an embodiment not shown, the first drive assembly may also be a T-head or a rotary lock head.

Preferably, as shown in fig. 7, the operation portion 131 is configured as an operation hole. Thus, the head of the first driving assembly 171 extends into the operation hole to be connected with the operation part 131, and the operation is simple.

The axial direction of the operation hole is parallel to the longitudinal direction (an example of the horizontal direction) of the case 110. Thus, the opening of the operation hole is directed to the side of the case 110 in the longitudinal direction of the case 110. Thereby, it is convenient to extend the head of the first driving assembly 171 into the operation hole.

It will be appreciated that in an embodiment not shown, the axial direction of the pivot axis of the bottom door may also be parallel to the width direction of the cabinet. The first slider is located at a side portion of the case in the width direction of the case. At this time, the axial direction of the operation hole is parallel to the width direction of the case 110. The opening of the operation hole faces to the side of the case in the width direction of the case.

It will be appreciated that in an embodiment not shown, the axial direction of the operation hole may be parallel to the height direction of the case. The opening of the operation hole faces to the upper side of the box body. At this time, the hanger only needs to be provided with the first driving assembly. The length direction of the first driving component is parallel to the height direction of the lifting appliance, so that the first driving component can extend into the operation hole and is connected to the first sliding piece.

Referring to fig. 7, the container further includes a lock 165. The locking member 165 is movably coupled to the housing 110 along the length of the housing 110. With the first slider 130 in the slide-lock position, the lock member 165 faces the operation hole. Thus, the lock 165 can extend into the operating hole. In this way, the lock member 165 can fix the first slider 130 in the slide-lock position, thereby preventing the first slider 130 from moving out of the slide-lock position.

The container also includes a lock spring 166. The lock spring 166 may be a cylindrical spring. The latch elastic member 166 is connected to the latch 165 and the case 110. The lock elastic member 166 is used to apply a force to the lock 165 that can bring the lock 165 into the operation hole. Thus, the lock member 165 can automatically extend into the operation hole when the first slider 130 moves to the slide-lock position by the lock member elastic member 166. When the head of the first driving assembly 171 is inserted into the operation hole, the head of the first driving assembly 171 pushes the locking member 165 out of the operation hole, thereby unlocking the locking of the first slider 130 by the locking member 165.

Preferably, the lock 165 has a lock guide ramp 167. The upper end of the latch guide slope 167 is farther from the center of the housing 110 than the lower end thereof. Thus, when the first slider 130 moves from the slide unlock position to the slide lock position, the first slider 130 contacts the lock guide slope 167, and thus the lock 165 moves in the longitudinal direction of the case 110, thereby compressing the lock elastic member 166. The compressed latch spring 166 applies a force to the latch 165 that causes the latch 165 to compress the first slider 130. When the locking member 165 is aligned with the operating hole, the locking member 165 is inserted into the operating hole by the locking member elastic member 166. Thereby facilitating the operation of the lock 165 into the operation hole.

It should be noted that, when the first slider 130 is moved from the sliding unlock position to the sliding lock position, the container (including the structure of the case 110, the structure and position of the lock hook 150, the structure and position of the link assembly 140, the structure and position of the first slider 130, and the structure and position of the bottom door 120) can hook the lock hook 150 to the hook portion 121 and can move the bottom door 120 to the closed position.

Second embodiment

Referring to fig. 8, in the second embodiment, the first slider 230 at the sliding unlock position can move away from the sliding lock position to the sliding add-on position. In this way, the angle at which the bottom door is opened can be increased. Thus, the speed at which the bottom door rotates in the process of moving from the slide unlock position to the slide open position is proportional to the moving speed of the first slider 230.

The container further includes a flexible member 261 and a second slider 265. The second slider 265 is movably connected to the case in the height direction of the case. The box body is also provided with a second guide rail. The length direction of the second guide rail extends along the height direction of the box body. The second slider 265 is connected to the second rail. The second slider 265 and the second guide rail cooperate to guide movement of the second slider 265 in the height direction of the case. The second slider 265 is pivotally connected to the pivot.

The flexible member 261 may be an iron chain or a rope. One end of the flexible member 261 is connected to the connecting member 264, and is further connected to the first slider 230 through the connecting member 264. The other end of the flexible member 261 is connected to the second slider 265. Thus, the flexible member 261 is connected to the shackle through the pivot member. Thus, when the bottom door is closed, the first slider 230 applies a force to the latch hook through the flexible member 261, so that the latch hook rotates to the hooking position. Thus, the structure of the container is simple.

The container also includes a shackle spring 262. The latch hook elastic member 262 may be a cylindrical spring. One end of the latch hook elastic member 262 is connected to the connecting member 264, and is further connected to the first slider 230 through the connecting member 264. The latch hook elastic member 262 is located above a portion of the second slider 265 in the height direction of the case.

During the movement of the first slider 230 from the sliding locking position to the sliding unlocking position, the latch hook elastic member 262 starts to contact the second slider 265, and the first slider 230 continues to move toward the sliding unlocking position, so that the latch hook elastic member 262 is compressed. The first slider 230 applies a downward force to the second slider 265 through the compressed latch hook spring 262. When the first slider 230 moves to the slide unlock position, the force rotates the shackle to the unhook position.

With the first slider 230 in the slide-unlock position, the shackle elastic 262 can also be compressed to allow the first slider 230 to continue to move downward. Thus, the latch hook elastic member 262 continues to be compressed when the first slider 230 moves from the slide-unlock position toward the slide-add position. In this way, the openable angle of the bottom door can be further increased.

It will be appreciated that in an embodiment not shown, the other end of the shackle spring may also be connected to the second slider, and thus to the shackle via the second slider.

Preferably, neither the latch hook elastic member 262 nor the flexible member 261 protrude from the outer contour of the case. Thereby facilitating transportation of the container.

Other arrangements of the second embodiment are substantially the same as those of the first embodiment, and will not be described here.

The gear 371 is rotatably connected to the housing. The rack 372 is connected to the first slider 330. The length direction of the racks 372 extends in the height direction of the case. The gear 371 is meshed with the rack 372. The first driving wheel 373 and the gear 371 are coaxially disposed, and are connected to the gear 371. Thus, the gear 371 rotates with the first drive wheel 373. The second drive wheel 374 is rotatably connected to the housing. The first drive wheel 373 and the second drive wheel 374 are sprockets. The chain 375 connects the first drive wheel 373 and the second drive wheel 374. Thus, the first drive wheel 373 and the second drive wheel 374 can rotate together. The manual portion 376 is coupled to the second drive wheel 374 for rotating the second drive wheel 374.

The operator may manually operate the manual portion 376 to rotate the second drive wheel 374. The rotating second driving wheel 374 drives the first driving wheel 373 to rotate, and further drives the gear 371 to rotate. The rotated gear 371 drives the rack 372 to move in the height direction of the case, thereby driving the first slider 330 to move in the height direction of the case.

It will be appreciated that in an embodiment not shown, the drive assembly includes a motorized portion. The motorized section includes a pneumatic or hydraulic cylinder. The motor is connected to the case. The motorized part is connected to the first slider for driving the movement of the first slider in the height direction of the case.
