Background
Conventionally, in a mobile table such as a bedside table used while being arranged at a predetermined position by moving from one side of a bedside in a width direction of a bed, or a bed table used while being arranged at a predetermined position by moving from a foot side of a bed in a length direction of the bed, there is known a mobile table provided with a lock operation mechanism for immobilizing casters by a user using the table.
As a conventional technique, for example, the following structure is disclosed (see patent document 1): in a bedside table, a foot part provided with casters is provided with a lock mechanism having: a grounding member capable of moving up and down; an operation unit for moving the grounding member up and down; and a holding unit configured to hold the caster in a state of floating from the ground by pressing the ground contact member toward the ground by the operation unit to ground the ground contact member.
As another example, there is disclosed an operating mechanism (see patent document 2) in which four casters disposed on the floor are operated by an operating wire composed of an inner wire and an outer wire at the same time in a head rest used near the bed, and an operating lever thereof is disposed at the upper end of a side plate of the head rest.
However, in the lock mechanism as in patent document 1, since the operation site is located on the foot side, it is difficult to operate, and in order to operate all the casters of the foot, there is a problem that the operation becomes complicated because, for example, two operations are required for each side.
Further, in the operating mechanism as in patent document 2, since the operating lever is provided at the upper portion of the head rest, the operation is easy, and all the casters can be simultaneously brought into the locked state by one operation, but since the operating lever is disposed at the upper end portion of the side plate, it cannot be a large handle, and therefore, there is a problem that it is difficult to reduce the operating force.
Therefore, the following structure is proposed (see patent document 3): in a lifting table provided with casters having a lock mechanism, an operation lever is provided at a lower portion of a table, and an operation lever for operating an operation pin of the lock mechanism of the casters is provided at a leg portion, so that the locking operation of the casters having the lock mechanism is performed.
According to such a configuration, in the elevating type movable table, the operation portion for bringing the casters into the locked state is provided to the table top, so that the locking operation can be easily performed, and the operation force can be reduced while operating all the casters at once.

First, the overall structure of the mobile table 1 according to the present embodiment will be described with reference to the drawings.
As shown in fig. 1 and 2, the table 10 is formed in an elongated rectangular shape that can be disposed across the bed device (not shown) in the width direction of the bed device.
The table 10 includes an upper surface 101 and a lower surface 102.
The column parts 20 are disposed at both longitudinal ends of the lower surface 102, and the movable table 1 is formed in a door shape. The base of the column part 20 includes a leg part 30, and the leg part 30 includes a caster 31.
As shown in fig. 2, a table reinforcing member 103 is provided on the lower side of the lower surface 102 so as to be long in the longitudinal direction. The table reinforcing member 103 is configured to be foldable with the column part 20.
As shown in fig. 1 and 3, a lock release mechanism 40 is provided below the side end portion of the table 10 in the longitudinal direction. A bendable and extendable operation wire 41 constituting a part of the lock release mechanism 40 is laid between the table top 10 and the table reinforcing member 103.
As shown in fig. 3 and 4, the column part 20 is configured to be expandable and contractible.
The column part 20 includes a1 st column member 201 and a 2 nd column member 202, and the column part 20 is configured to be expanded and contracted by moving the 2 nd column member 202 together with the table 10 in the vertical direction in the figure along the 1 st column member 201.
The 1 st column member 201 is provided on the leg 30 side, and the 2 nd column member 202 is provided on the table 10 side, and the height of the table 10 can be adjusted by the user by performing an operation of lifting or pressing the table 10 by a drive mechanism not shown.
An expansion and contraction guide structure 21 is formed inside the column part 20, and the expansion and contraction guide structure 21 guides the operation wire 41 disposed inside the column part 20 in accordance with the expansion and contraction operation of the column part 20.
The telescopic guide structure 21 includes the 1 st guide member 211 and the 2 nd guide member 212, and the telescopic guide structure 21 is configured to extend and contract by moving the 2 nd guide member 212 in the vertical direction in the drawing along the 1 st guide member 211 within a range in which the column part 20 extends and contracts.
The 1 st guide member 211 is provided on the 1 st column member 201 side, and the 2 nd guide member 212 is provided on the 2 nd column member 202 side, and is configured to guide the operation wire 41 arranged inside the column section 20 so as not to bend even if the length of the operation wire changes due to the expansion and contraction of the column section 20.
As shown in fig. 5(a) and (b), in the column part 20, the 2 nd column member 202 is attached to the table reinforcing member 103 so as to be foldable, and the table reinforcing member 103 is provided at the lower portion of the table top 10.
The 2 nd pillar member 202 is integrally provided with a pillar coupling portion 203 attached to the table reinforcing member 103.
As shown in fig. 5(a), the strut connecting portion 203 includes a pivotal support portion 203a and fixing portions 203b and 203 c.
The column coupling portion 203 pivotally supports the column coupling portion 203 on the table reinforcing member 103 so as to be rotatable about the pivot support portion 203 a.
When the column part 20 is folded, the rotation support part 203a functions as a fulcrum of the rotation column coupling part 203, and guides the rotation of the column coupling part 203 along the elongated guide hole 103a formed in the table reinforcing member 103. The pivot support portion 203a is engaged with the guide hole 103a via a support member not shown in the table use state.
The fixing portions 203b and 203c are fixed to mounting holes 103b and 103c formed in the table reinforcing member 103 by fastening members not shown in the drawings in a table use state.
By providing the column connecting portion 203 in this way, when the movable table 1 is used, the 2 nd column member 202 can be reliably fixed to the table reinforcing member 103 at two locations of the fixing portions 203b and 203c by the fastening members in a state where the rotation supporting portion 203a is engaged with the supporting member.
On the other hand, when the movable table 1 is not used, the 2 nd column member 202 can be simply folded and compactly stored in a state where the column coupling member 203 is coupled to the table reinforcing member 103 by the pivotal support portion 203a simply by removing the fastening members of the fixing portions 203b and 203 c.
As shown in fig. 6(a) and (b), the leg 30 includes a caster 31, a lock mechanism 32 that locks and unlocks a rotational operation of the caster 31, and a leg frame 33 in which the caster 31 and the lock mechanism 32 are assembled.
As shown in fig. 6(a), the leg frame 33 is formed long in the width direction of the table 10, and casters 31 are attached to both ends thereof.
As shown in fig. 6(b), the caster 31 is pivotally supported on a mounting bracket 331 that mounts an end of the z-leg frame 33 so as to be rotatable about a mounting shaft 311. A brake shoe support shaft 322 that supports a brake shoe 321 is attached coaxially with the attachment shaft 311 so as to be movable in the axial direction of the attachment shaft 311.
As shown in fig. 6 b, the brake shoe support shaft 322 is biased by a coil spring 323 in a direction (upward in the drawing) in which the brake shoe 321 is separated from the caster 31.
The brake shoe 321 is driven to operate by an operating arm 324 constituting the lock mechanism 32. The brake shoe support shaft 322 abuts against a stopper 324c provided to protrude from the operation arm 324, thereby setting the position of the brake shoe 321.
One end 324a of the operation arm 324 is pivotally supported by a support 331a via a support shaft 325, the support 331a being provided outside the mounting position of the caster 31 (the position of the mounting shaft 311) of the mounting bracket 331, and the other end 324b being connected to the inner wire 411 via a connecting pin 326. At the other end 324b, a long hole-shaped guide hole 324c for guiding the movement of the coupling pin 326 is formed.
The operation arm 324 is disposed across the center portion from the end portion of the foot frame 33.
The operation arm 324 rotates the operation other end portion 324b in the vertical direction with the support shaft 325 as a fulcrum by the inner wire 411.
When the other end 324b of the operating arm 324 is pivoted upward, the stopper 324c is displaced upward, and the brake shoe 321 is moved upward by the spring force of the coil spring 323 and in a direction away from the caster 31, that is, in a direction to release the lock of the caster 31.
On the other hand, when the other end portion 324b is rotated downward by the spring force of the coil spring 327, the stopper portion 324c is displaced downward, and the brake shoe 321 is moved downward against the spring force of the coil spring 323 in a direction of coming into contact with the caster 31, that is, in a direction of locking the caster 31.
The operation arm 324 is connected to the other end 324b of the operation arm 324 of the other caster 31 disposed at the other end of the foot frame 33 in the central portion of the foot frame 33 by a connection pin 326.
With this configuration, the lock mechanisms 32 at both ends of the operating arm 324 can be simultaneously operated by operating the inner wire 411 coupled to the coupling pin 326.
Next, a characteristic structure of the lock release mechanism 40 of the present embodiment will be described with reference to the drawings.
FIG. 7 is an explanatory view showing the overall structure of a lock release mechanism constituting the movable table, FIG. 8 is an explanatory view showing an installation state of an operation wire constituting the lock release mechanism, fig. 9 is an explanatory view showing a structure of coupling of the operation wire from the table side to the stay side, FIG. 10 is an explanatory view showing a structure of a wire rod constituting the lock release mechanism, FIG. 11 is an explanatory view showing a structure of an operation lever constituting the lock release mechanism, FIG. 12 is an explanatory view showing the arrangement of a stopper button constituting the lock release mechanism, FIG. 13 is an explanatory view showing the positional relationship between the stopper button and a wire rod, fig. 14 is an explanatory view showing a structure of the detent button, and in fig. 15, (a) is a sectional view showing an attached state of the detent button, and (b) is an explanatory view showing a state in which the detent button is operated.
As shown in fig. 1, 2, and 7, the lock release mechanism 40 includes an operation wire 41, a wire rod 42, an operation shaft 43, an operation lever 44, a stopper button 45, and an operation portion cover 46.
As shown in fig. 6 to 10, the operation wire 41 includes an inner wire 411 and an outer wire 412 that operate, and the operation wire 41 is connected to the wire rod 42 on the table 10 side and the lock mechanism 32 of the caster 31 on the leg portion 30 side and is operated to lock and unlock.
As shown in fig. 8, one end of the operation wire 41 is attached to the wire rod 42, and as shown in fig. 9, the operation wire is laid from the table 10 side to the leg 30 side through the inside of the column part 20, and as shown in fig. 6(a), the other end is attached to the operation arm 324 through the connection pin 326 of the lock mechanism 32 of the caster 31 of the leg 30.
And, the operation wire 41 is curvedly laid in the following manner: the locking/unlocking operation of the locking mechanism 32 of the caster 31 can be performed within the range in which the column part 20 extends and contracts, and as shown in fig. 7, a length margin can be maintained between the table top 10 and the table reinforcing member 103.
Specifically, as shown in fig. 10, in a state where one end portion of the inner wire 411 is attached to the wire rod 42, and as shown in fig. 8, one end portion of the outer wire 412 is attached to the operation wire attachment portion 102a provided near the center of the table reinforcing member 103 via the coupling member 412a, the operation wire 41 is bent in an arc shape near the center of the table reinforcing member 103 and is left as it is, as shown in fig. 9, drawn around the leg portion 30 from the side end portion of the table reinforcing member 103 via the wire guide portion 48 and through the inside of the column portion 20, as shown in fig. 6(a), the other end portion of the inner wire 411 is attached to the lock mechanism 32 of the caster 31, and the other end portion of the outer wire 412 is attached to a part of the leg portion 30.
The wire guide portion 48 is formed of a curved cylindrical body, and guides the wire so as to avoid an extremely small curve R when the operation wire 41 is displaced due to expansion and contraction of the column portion 20.
As shown in fig. 10, the wire rod 42 is disposed in the vicinity of the center of the table reinforcing member 103 at the lower portion of the table top 10, and is operated by connecting one end portion of the inner wire 411, so that the lock mechanisms 32 of the casters 31 of the leg portions 30 disposed at two positions at both end portions of the mobile table 1 to which the other end portion of the inner wire 411 is connected are simultaneously operated.
As shown in fig. 7, the operation shaft 43 is provided long along the longitudinal side end of the table reinforcing member 103, and is rotatably attached to the table reinforcing member 103. A wire rod 42 is integrally provided near the central portion of the operation shaft 43 in the longitudinal direction, and the wire rod 42 integrally rotates with the rotation of the operation shaft 43.
As shown in fig. 11, the operation lever 44 is a lever portion having a substantially L shape with one end protruding outward, and the other end integrally provided with the operation shaft 43 to rotate the operation shaft 43.
In the present embodiment, the operation levers 44 are provided at both end portions of the operation shaft 43.
The stopper button 45 functions as an unlock holding member that holds the unlock state of the lock mechanism 32 of the caster 31 by the unlock mechanism 40.
As shown in fig. 12 and 13, the operation portion cover 46 covers the vicinity of the wire rod 42, and the stopper button 45 is disposed at a predetermined position with respect to the wire rod 42.
As shown in fig. 14, 15(a) and 15 (b), the stopper button 45 is formed of a cylindrical body having a flange 45a formed on one end side and an opening on the other end side, and the coil spring 451 is disposed inside the cylindrical body. An abutting portion 45b protruding to the outside of the cylindrical body is formed along the outer periphery at the end of the other end side of the stopper button 45.
The stopper button 45 is normally biased by a coil spring 451 to protrude outward from the operation unit cover 46.
As shown in fig. 12, the flange portion 45a functions as a stopper for preventing the stopper button 45 from entering the inside of the operation portion cover 46 when the stopper button 45 is pushed into the operation portion cover 46.
In the present embodiment, the stopper button 45 is configured such that, in a state where the operation portion cover 46 is pushed in as shown in fig. 12, the stopper button 45 is configured to abut against a part (rib 42a) of the operated wire rod 42 and to maintain the state where the wire rod 42 is operated as shown in fig. 13.
Next, an operation of allowing the casters to rotate by the lock release mechanism 40 when the movable table 1 is moved will be described with reference to the drawings.
When the movable table 1 is moved, first, the operation lever 44 of the lock release mechanism 40 is grasped and turned upward by a predetermined amount.
The wire rod 42 is rotated forward in conjunction with the operation of the operating lever 44, and the inner wire 411 is pulled out by a predetermined amount, and as shown in fig. 6(a), the coupling pin 326 connected to the inner wire 411 is lifted.
As a result, the other end 324b of the operating arm 324 is rotated upward, and the stopper 324c is displaced upward as shown in fig. 6 (b). As a result, the coil spring 323 lifts the brake shoe 321 together with the brake shoe support shaft 322, thereby releasing the locked state of the brake shoe 321 of the caster 31 and allowing the caster 31 to rotate.
At this time, in a state where the operation lever 44 keeps the wire rod 42 operating, as shown in fig. 12 and 13, the stopper button 45 is pushed into the operation portion cover 46, and the held operation lever 44 is released at a position where the abutting portion 45b of the stopper button 45 abuts against a part of the wire rod 42, and the part of the wire rod 42 abuts against the stopper button 45, thereby keeping the operating state.
Thus, since the locking of the caster 31 is released, the table can be continuously moved without maintaining the state where the user grips the operation lever 44. This reduces the burden of operating the operation lever 44 when moving the table 10.
Next, an operation of locking the caster 31 after the movement of the movable table 1 is completed will be described with reference to the drawings.
When the movement of the movable table 1 is completed and the caster 31 is returned to the locked state, the operation lever 44 held at the predetermined position is further gripped. When the operating lever 44 is further gripped, the wire rod 42 is separated from the stopper button 45, and therefore the locked state between the wire rod 42 and the stopper button 45 is released, and the stopper button 45 is pushed out to the outside of the operating portion cover 46 by the spring force of the coil spring 451 and returns to the original state.
When the grip state of the operation lever 44 is released and the operation lever returns to the original state, the other end portion 324b of the operation arm 324 is rotated downward by the spring force of the coil spring 327 of the lock mechanism 32 as shown in fig. 6(a), and the stopper portion 324c is displaced downward as shown in fig. 6 (b). Thus, the stopper 324c presses the brake shoe 321 together with the brake shoe support shaft 322, and the caster 31 is locked by the brake shoe 321.
Thus, the user can release the holding state of the wire rod 42 by the stopper 324c by further grasping the operating lever 44 from the unlocked state, and can easily return the caster 31 to the locked state.
As configured as above, according to the present embodiment, the traveling table 1 includes: the table 10, the column part 20 for supporting the table 10, and the leg part 30 including the caster 31 and the lock mechanism 32, the portable table 1 includes a lock release mechanism 40 for locking/unlocking the caster 31 by wire operation, and the lock release mechanism 40 includes: an operation wire 41 connected to the lock mechanism 32 of the caster 31 and operated to lock/unlock the caster; a wire rod 42 for operating the operation wire 41; an operation shaft 43 for rotating the wire rod; an operation lever 44 for rotating the operation shaft 43; and a stopper button 45 for maintaining the unlocked state by the unlocking mechanism 40, so that the caster 31 can be always locked in the normal state, and the safety can be improved by not moving the traveling table in use, and the unlocked state can be easily maintained by the stopper button 45 when unlocking, so that the operability of the locking/unlocking operation can be improved, and the operation of moving the traveling table 1 can be continuously performed by discontinuously operating the operation lever 44 by a simple operation.
In the present embodiment, the operating state of the wire rod 42 is held by the stopper button 45, but the present invention is not limited to this as long as the operating state of the operating wire 41 for operating the lock mechanism 32 is held, and for example, a stopper for holding the operating state of the operating lever 44 or a rotation restricting member for restricting the rotational operation of the operating shaft 43 may be provided.
In the present embodiment, as shown in fig. 15(a) and (b), the stopper button 45 functioning as the lock release holding member is configured such that the stopper button 45 enters the operation portion cover 46 when the lock release operation is performed.
Hereinafter, example 2 of the stopper button 45 constituting the lock release mechanism of the present embodiment will be described.
Fig. 16 is an explanatory view showing a structure of example 2 of the detent button constituting the lock release holding member of the present embodiment, and fig. 17(a) is a sectional view showing an attached state of the detent button of example 2, and (b) is an explanatory view showing a state where the detent button is operated.
In embodiment 2, as shown in fig. 16, the lock release holding member has the following structure: the operation portion cover 146 is provided with a guide portion 146a, and the stopper button 145 is attached so as to be movable along the guide portion 146 a.
Specifically, as shown in fig. 16, 17(a) and (b), a guide portion 146a for guiding the stopper button 145 is formed on the operation portion cover 146. The guide portion 146a is formed in a cylindrical shape.
The stopper button 145 includes a button portion 145a that moves along the outer periphery of the guide portion 146a and an abutting portion 145b that moves along the inner periphery of the guide portion 146 a. The push button portion 145a and the contact portion 145b are integrally coupled by a mounting screw 145 c.
The push button portion 145a is formed of a cylindrical body having an attachment portion 145a1 on one end side to which the contact portion 145b is attached and an opening on the other end side, and a coil spring 1451 is disposed inside the cylindrical body.
The contact portion 145b is formed in a columnar shape, and has a screw hole at one end portion to be fastened to the button portion 145a, and a flange portion 145b1 protruding outside the columnar body at the other end portion. The abutting portion 145b may be formed of a metal member.
As shown in fig. 17(a) and (b), the flange portion 145b1 functions as a stopper for preventing the stopper button 145 from being ejected from the operation portion cover 146, and abuts against a part of the wire rod 42 to maintain the operating state of the wire rod 42.
In this embodiment, it is constituted in the following manner: when the lock release holding operation is performed, as shown in fig. 17(a) and (b), the stopper button 145 is displaced toward the operation portion cover 146 by a predetermined amount, and the contact portion 145b protrudes into the operation portion cover 146 and comes into contact with a part (rib 42a) of the wire rod 42 to be operated, thereby holding the state in which the wire rod 42 is operated.
Since the above configuration is adopted, according to embodiment 2, when the lock release holding operation is performed by pressing the stopper button 145, the contact portion 145b is guided by the guide portion 146a of the operation portion cover 146 and smoothly operates, and thus operability can be improved.
The present invention is not limited to the above-described embodiments and examples, and various modifications can be made within the scope of the claims. That is, embodiments obtained by combining technical means appropriately modified within a range not departing from the gist of the present invention are also included in the technical scope of the present invention.
