[Patent Document 2] Japanese Patent Application Laid-Open No. 2001-170531

TECHNICAL FIELD The present invention relates to a wallpaper exhalation apparatus, and in particular, a leg supporting a main body of the exhalation apparatus and a leg mounted at four corners of the frame, the legs being freely open and closed in the longitudinal direction of the frame and axially supported by the upper end. The present invention relates to a technology configured to easily open and close the legs and securely lock the legs into an open state and a closed state, respectively.

As shown in the side view of Fig. 13, the wallpaper caller is composed of a caller unit body A and a leg portion B provided with a roller group for carrying out a pool box, grass feed and paper conveying. And the leg part B is comprised by the frame 1 which supports the swelling machine main body A, and the leg 2 of the four corners of a frame, and does not increase a height normally when carrying a wallpaper swelling machine in a car etc. The leg 2 is foldable. In this case, it has been known in the art to fix with a knob bolt or nail as a method of fixing in an open state when the leg 2 is used. However, the conventional fixing method is stable, but the work is inconvenient, on the contrary, there is a problem such as easy work but lack of stability.

Thus, for example, it has been proposed to provide a locking member which abuts on the side of the leg from the rotational point of the leg and is urged by the urging means and locks the leg in the open state when it is in the open state. See Patent Document 1)

In addition, the structure in which the locking member abuts inward from the pivot point of the leg is provided by an extension part for contacting the locking member upwardly (inside) at the pivot point of the leg to the outside of the pivot point with the part closed. Since the width of the swelling machine becomes larger (when the distance between the legs is constant), the upper end of the leg is pivotally supported by the supporting member installed on the frame. It is also proposed to install the locking projection below and the locking means engaged with the locking projection of the leg for easy operation and stability, and further shorten the dimensions of the swelling machine, especially in the width direction. (For example, refer patent document 2).

However, the conventional wall paper wiper is in contact with the side of the leg inward from the rotational point of the leg when it is in the open state, and is provided with a locking member which is urged by the urging means to lock the leg in the open state as described above. Similarly, there is a problem that an extension part is required at the inside of the rotational point of the leg, and the part is pushed outward in the closed angle, and the leg is locked inward from the rotational point. The problem is that the state is not stable.

In addition, the upper end of the leg is rotatably supported on the support member installed in the frame, the locking projection is installed below the pivot point of the leg, and the locking member is engaged with the locking projection of the leg. As described above, the work is easy and stable, and the widthwise dimension of the swelling machine does not increase by opening and closing of the legs, but there is a problem to be solved even more.

That is, there are various means for fixing the legs of the wallpaper caller in the open state as mentioned above, but they are all dedicated for the opening of the wall. They are means for fixing the legs in the closed state to stabilize the legs when the legs are folded and transported to the vehicle. It is necessary to prepare separately. However, if the closure means for closing is separately provided, it is necessary to release the closing means for opening and closing when opening and closing, and then operate the opening means for fixing in the fixed direction. After closing, it is necessary to operate the closing means for closing in a fixed direction, which is complicated to load and unload when transporting the vehicle.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an easy opening and closing operation of the foot, and further provide a wallpaper caller which can be reliably locked in the open state and the closed state, respectively.

In the wallpaper caller of the present invention, the wallpaper caller includes a leg supporting the main body of the caller and a leg part which is mounted at four corners of the frame and is open and closed in the longitudinal direction of the frame. A locking projection provided at a position separated by a predetermined dimension from an upper end shaft supporting position of the leg to a lower end side, a first notch and a pinched portion or pin of the tip portion that can engage with the locking projection of the leg when the leg is in an open state; A first locking lever rotatable about a first point fixed to the side, a second notch and a pin or long blood of the distal end that can engage with the locking projection of the leg when the leg is in a closed state; A locking mechanism comprising a second locking lever rotatable about a fixed second point, wherein the first locking The tip of the burr and the tip of the second locking lever are connected by engagement of the blood and pins, and the first locking lever and the second locking lever are interlocked and rotated in opposite directions. The first notch of the first locking lever engages with the locking projection of the leg to lock the leg in an open state, and when the leg is closed, the second notch of the second locking lever engages with the locking projection of the leg. It is configured to lock the leg in the closed state.

This wallpaper calliper is used with the legs open and folded (closed) so that the height does not increase during transportation, and the legs are free to rotate around the point of the upper end. The locking and unlocking operations during the opening and closing operations are performed by rotational operation of one locking lever, for example, the first locking lever. In that case, the first locking lever is rotated in one direction (locking direction) in the opening state. The legs are locked in the open state by engaging the first notch with the locking projections of the legs. In closing, when the first locking lever is rotated in the opposite direction (release direction), the first notch is released from the locking projection of the leg and the lock is released. In that state, the leg is rotated about the upper end point to close and the leg is closed. When the first locking lever is rotated in the lock direction in the fully closed state, the second locking lever rotates in conjunction with the second notch and engages with the locking protrusion of the leg to lock the leg in the closed state. When the first locking lever is rotated in the unlocking direction, the second locking lever rotates in conjunction with the second lock lever. The second lock is released from the locking projection of the leg, and the lock is released. When the first locking lever is rotated in the locking direction with the legs completely open, the first notch engages with the locking protrusion of the leg to lock the leg in an open state. In this way, the legs can be reliably locked in the open and closed states, respectively, and further, the locking or unlocking of the legs can be performed by the rotation operation of one locking lever. Therefore, for example, opening and closing work at the time of loading and unloading when the wallpaper caller is carried by a vehicle or the like becomes easy. The wallpaper caller consists of two locking levers that interlock the locking levers for fixing the legs in the open and closed states, so that the first and second notches engage at substantially right angles with the locking projection at the time of opening and closing. It can be configured to make the lock more secure.

In addition, the wallpaper caller of the present invention is a wallpaper caller having a leg supporting the body and a leg portion consisting of a leg mounted on the four corners of the frame and the upper end is axially supported freely open and closed in the frame length direction. A locking projection provided at a position spaced apart from the upper end shaft supporting position of the leg by a predetermined dimension from a lower end side thereof, a first notch engageable with the locking projection of the leg when the leg is in an open state, and the leg is in a closed angle. And a second notch engageable with the locking projection of the leg, the locking lever being rotatable about a point fixed to the frame side, and the first notch being the system of the leg when the leg is opened. When the legs are locked in an open state by turning to a position engaged with the ground protrusion and the legs are closed The second notch can be configured to lock the leg in the closed state by rotating it to a position engaged with the locking projection of the leg.

This wallpaper calliper is used with the legs open and folded (closed) so that the height does not increase during transportation, and the legs are free to rotate around the point of the upper end. In the open state, the leg is locked in the open state by rotating the lock lever in one direction (lock direction) and engaging the first notch with the locking projection of the leg. When closing, the locking lever is rotated in the opposite direction (release direction), and the first notch is released from the locking projection of the leg to release the lock.In that state, the leg is rotated around the upper point to close and the leg is completely closed. When the locking lever is rotated in the lock direction in the state, the second notch engages with the locking protrusion of the leg to lock the leg in the closed state. When opening, the locking lever is rotated in the release direction, and the second notch is released from the locking projection of the leg, and the lock is rotated in such a state that the leg is opened and the lock lever is rotated in the locked direction. The first notch engages with the locking projection of the leg to lock the leg into an open state. In this way, the legs can be reliably locked in the open and closed states, respectively, and the legs can be locked or unlocked by rotating the lock lever. Therefore, for example, opening and closing work at the time of loading and unloading when the wallpaper caller is carried by a vehicle or the like becomes easy. This wallpaper caller has one locking lever for fixing the legs in the open and closed states, and at least the number of parts of the locking mechanism is solved.

In addition, the wallpaper caller of the present invention by installing the urging means for urging the legs in the closed angle direction, for example, to prevent the legs open unintentionally and strongly in their own weight when the wallpaper caller is released from the car by unlocking the legs. You can prevent work in the way.

Best Mode for Carrying Out the Invention

[First Embodiment]

1 and 2 show a first embodiment of the present invention.

1 (a) and 1 (b) are cross-sectional views showing a cross section perpendicular to the frame length direction showing the configuration of the locking mechanism of the wallpaper calliper leg and a cross-sectional view showing a vertical cross section along the frame length direction. )-(f) is explanatory drawing which shows the opening-and-closing operation | movement of the leg part of a wallpaper caller.

The wallpaper caller of this embodiment is constituted by a caller base body and each part having a roller group for carrying out a box, grass feed, paper conveyance, and the like. The call base member has a conventionally known configuration as shown in FIG. In addition, each part is composed of a frame (1) for supporting the main body and the legs (2) of the four corners of the frame, the legs are foldable.

The leg 2 of the leg portion is pivotally rotatably supported on the support shaft 4 fixed to the support member 3 attached to the support member 3 in which the upper end is arranged in the vertical direction at the four corners of the frame 1, and the length of the frame 1 It is an opening-and-closing material in the direction (the front-back direction of FIG. 1 (a), the left-right direction of FIG. 1 (b)).

In addition, the leg portion 2 has the front-rear direction of the frame 1 (the left-right direction in FIG. The locking projection 5 is provided so as to protrude toward the inside of FIG. 1 (b). In addition, the locking projection 5 is fixed to the longitudinal inner surface of the frame 1 of the leg 2 in the illustrated example, but is not limited thereto.

Since each part of the wallpaper caller locks the leg 2 in the open state and the closed state and releases the lock to enable the opening and closing operation, the legs 2 are held in the open state. It has a first notch 6 engageable with the projection 5, is rotatable about a first point pin (first point; 7) fixed to the frame 1, and locks the leg 2 in an open state. A second fixed lever to the frame 1 having a second notch 9 engageable with the locking projection 5 of the leg 2 when the first locking lever 8 and the leg 2 are in the closed state; It is rotatable about the point pin (second point; 10) and when the leg 2 is closed, the second notch 9 rotates to the position where it engages with the locking projection 5 of the leg 2. A second locking lever 11 for locking 2) in a closed state is provided.

The first locking lever 8 and the second locking lever 11 are engaged with the blood 12 of the distal end portion of the first locking lever 8 and the pin 13 of the distal end portion of the second locking lever 11. Connecting and fixing both ends of the pivoting handle bar 14 to the first locking lever 8 of each pair of legs 2 before and after, as shown in Fig. 1 (b), and the handle bar 14 A locking mechanism configured to rotate the first locking lever 8 by interlocking operation and to rotate the second locking lever 11 in association with each other is provided.

Then, as shown in Fig. 1 (a), a spring member 7a is mounted on the first branch pin 7, and one end thereof is hooked to the first locking lever 8, and the first locking lever 8 is rotated in the locking direction. Is urging to.

As shown in Fig. 2, the wallpaper caller rotates the first locking lever 8 in the locking direction (clockwise in Fig. 2 (a)) by the force of the spring member 7a in the open state, and the first notch. By engaging 6 with the locking projection 5 of the leg 2, the locking projection 5 contacts and engages with the 1st notch 6 substantially perpendicularly.

When closing, the first locking lever 8 is rotated in the release direction (counterclockwise in Fig. 2 (b)) by operating the handle bar 11 so that the first notch 6 is connected to the leg 2 system. The lock is released from the protruding protrusion 5, and in this state, the leg 2 can be closed by rotating about the support shaft 4 (upper end point) by hand (Fig. 2 (b), (c), (d). )Reference].

When the leg 2 is completely closed, the second notch 9 of the second locking lever 11 can engage the locking projection 5 of the leg 2 (Fig. 2 (e)).

In this state, the first locking lever 8 is rotated in the locking direction (clockwise in Fig. 2 (f)) because the spring force 7 is always applied to the first locking lever 8 in the clockwise direction by the spring member 7a. And the second locking lever 11 interlocks and rotates counterclockwise around the second point pin 10, and the second notch 9 engages with the locking projection 5 of the leg 2, (2) is locked in a closed state (see Fig. 2 (f)). At that time, as shown in Fig. 2 (f), the locking projection 5 contacts with the second notch 9 at substantially right angles to engage.

In addition, when opening, when the first locking lever 8 is rotated in the release direction (counterclockwise in FIG. 2E) by operating the handle bar 14, the second locking lever 11 rotates in conjunction with each other. , The second notch 9 is released from the locking projection 5 of the leg 2 to be unlocked (see Figs. 2 (d), (c) and (b)).

Then, in the state where the leg 2 is completely open, the first locking lever 8 is rotated in the locking direction (clockwise in FIG. 2 (a)) by the spring member 7a, and the first notch 6 is the leg. In conjunction with the locking projection 5 in (2), the leg 2 is locked in an open state (see Fig. 2 (a)).

3 and 4 show a modification of the first embodiment of the present invention. Fig. 3 is a sectional view (a) showing a cross section perpendicular to the frame length direction showing the configuration of each part locking mechanism of the wallpaper caller and a cross sectional view (b) showing a vertical section along the frame length direction, and Fig. 4 is a leg of the wallpaper caller. It is explanatory drawing (a)-(f) which shows negative opening and closing operation | movement.

This modified example is provided with the spring 15 (preliminary means) which attaches the leg 2 to a closed angle direction in the wallpaper caller of 1st Embodiment. This spring 15 hangs one end to the pin 16 provided in the frame 1 side, and the other end hangs to the pin 17 provided in the front end side rather than the locking projection 5 of the leg 2. As shown in FIG. In addition, it is good also as a form which extends the locking projection 5, and uses the pin 17 together.

As shown in Fig. 4, the opening and closing operation of the leg portion of the wallpaper caller is basically the same as that of the first embodiment described with reference to Fig. 2, but by providing the spring 15 which biases the leg 2 in the closed angle direction. For example, it is possible to prevent the operation of the work by preventing the leg 2 from being opened unintentionally and powerfully when the wallpaper caller is released from the car by releasing the lock of the closed leg 2.

In this case, the second notch 9 engages with the locking projection 5 of the leg 2, and the handle bar 14 is removed from the state in which the leg 2 is locked in a closed state (see Fig. 4 (a)). When the first locking lever 8 is rotated in the release direction (counterclockwise in FIG. 4 (b)) by operation, the second locking lever 11 rotates in conjunction with the second notch 9 by the leg 2. The lock is released from the locking projection 5 of FIG. 4 (see FIG. 4 (c)), and the leg 2 can be rotated and opened in this state (see FIG. 4 (c), (d), (e)). ] At that time, even if the leg 2 is trying to open powerfully by its own weight, the leg 2 is biased toward the closing of the spring 15, and as the spring 15 extends, the force increases so that the leg 2 opens. As a result, the opening speed is slowed.

Finally, as opposed to the counter force of the spring 15, the leg 2 is opened and the first locking lever 8 is locked in the locking direction (Fig. 2 (a) by the force of the spring member 7a in the fully open state. ), The first notch 6 engages with the locking projection 5 of the leg 2 so that the leg 2 is locked in an open state (see FIG. 4 (f)). In the above embodiment, a pin may be provided on the first locking lever 8 side, and the blood may be formed on the second locking lever 11 side. In addition, at the time of closing, the opposite operation is performed, but since the force of the spring 15 acts in the closing angle, the force when closing the leg 2 by hand may be small.

Second Embodiment

In the first embodiment described above, the locking mechanism made up of the first locking lever 8 and the second locking lever 11 is fastened to every four legs 2 in order to lock the wallpaper caller in the open state or the closed state. Four sets are provided.

When the wall paper blower is in the open state, if the worker's hand or an object touches the first locking lever 8 or the second locking lever 11 at any time from the inside and the object unintentionally, both locking levers 8 and 11 ) May rotate.

The handle bar 14 is also rotated by the rotation of the first locking lever 8 on the front side (or the rear side), and the first locking lever 8 on the rear side (or the front side) is also rotated, so that the front and rear second locking levers 11 ), The notch 9 is released from the locking projection 5, and the lock is released and closed.

Therefore, in the second embodiment, even when the first locking lever 8 or the second locking lever 11 is pressed from the inside, the locking levers 8 and 11 are not rotated unless the handle bar 14 is operated. .

As shown in FIG. 5, since the basic structure is the same as that of 1st Embodiment, description of the part which attaches | subjects the same code | symbol to the same part, and overlaps is abbreviate | omitted.

A third point pin 31 and a projection 8a are formed on the first locking lever 8, and the handle bar 14 is held with the third point pin 31 as the axis. The notch 14a and the protrusion 14b are formed in the handle bar 14, and this notch 14a engages with the latching protrusion 3a provided in the support member 3. Since the handle bar 14 is always urged clockwise, the spring 32 is caught between the first point pin 7 and the projection 14b provided on the handle bar 14.

As shown in Fig. 6 (a), the wallpaper caller registers the handle bar at the same time as the first notch 6 of the first locking lever 8 engages with the locking projection 5 of the leg 2; The notch 14a of 14 is engaged with the locking projection 3a provided in the support member 3.

In this open state, even if the first locking lever 8 or the second locking lever 11 is pressed from the inside, and the first locking lever 8 tries to rotate about the first point pin 7, the first locking lever. The lever 8 is driven by the first point pin 7, the handle rod 14 is driven by a third point pin 31 away from the first point pin 7, and furthermore the handle bar 14. The handle bar 14 cannot rise because the notch 14a is engaged with the locking projection 3a. Therefore, the first locking lever 8 or the second locking lever 11 does not rotate unless the handle bar 14 is operated to release the engagement between the notch 14a and the locking projection 3a.

When closing, the handle bar 14 is operated to rotate, and as shown in FIG. 6 (b), when the notch 14a of the handle bar 14 is removed from the locking projection 3a and rotated again, FIG. 6 (c). As shown in), the lower part of the handle bar 14 abuts against the protrusion 8a of the first locking lever 8, and the first locking lever 8 is rotated counterclockwise with the first point pin 7 as the axis. Rotate to By this rotation, the first notch 6 of the first locking lever 8 is released from the locking projection 5 of the leg 2, and the lock is released. In this state, the support shaft 4 ), It can be rotated around and closed (see FIGS. 6 (d) to (f)).

When the leg 2 is completely closed, the second notch 9 of the second locking lever 11 engages and locks to the locking protrusion 5 of the leg 2, and the handle rod 14 is also notched. Since 14a locks in engagement with the locking projection 3a provided on the supporting member 3, the first locking lever 8 or the second locking lever 11 cannot be pushed from the inside to rotate (Fig. 6). (f)].

In addition, when the handle bar 14 is operated, the notch 14a of the handle bar 14 falls from the locking projection 3a and the first locking lever 8 is released in the release direction (Fig. 6 (e)). Direction), the second locking lever 11 is interlocked so that the second notch 9 is released from the locking projection 5 of the leg 2 (see Fig. 6 (d)).

In this state, the leg 2 can be rotated and opened (refer to FIG. 2 (d), (c), (b)). The notch 14a of the handle rod 14 engages with the locking projection 3a in the state where the leg 2 is completely open, and the first notch 6 of the first locking lever 8 is The legs 2 are locked in the open state in engagement with the locking projections 5 (see Fig. 2 (a)).

Third Embodiment

In the second embodiment described above, in order to prevent unnecessary closing angles of the wall paper blowing machine in the open state, the locking projections are formed on the handle bar 14 and engaged with the notches 14a on the support member 3. (3a) is provided to prevent rotation of the first locking lever 8 or the second locking lever 11.

As shown in FIG. 7, the basic structure is the same as that of 2nd Embodiment, and description of the part which attaches | subjects the same code | symbol to the same part, and overlaps is abbreviate | omitted.

In the third embodiment, like the second embodiment, the notch 14a is not provided in the handle bar 14, and the locking projection 3a is not provided in the support member 3 as well. Instead, when the handle bar 14 is axially supported by the point pin 31 as shown in Fig. 8, the hole 14c of the handle bar 14 is drilled larger than the diameter of the point pin 31 to prevent backlash. Have it.

In this way, if the handle bar 14 and the first locking lever 8 are backlashed and grounded, as shown in Fig. 8 (a), the handle bar 14 is always clockwise by the spring 32 in the open state. Since it is urged, the point pin 31 contacts the lower left of the hole 14c of the handle rod 14.

The first locking lever 8 or the second locking lever 11 of the front side (or the rear side) is unintentionally touched by an operator's hand or an object to touch the first locking lever 8 or the second locking lever 11. ) Rotates until the notch 6 of the first locking lever 8 is separated from the locking projection 5, as shown in Fig. 8 (b). Since the handle rod 14 starts to rotate after the point pin 31 contacts the upper left of the hole 14c, the rotation angle is maintained even if the handle rod 14 does not rotate or the handle rod 14 rotates slightly. It is smaller than the rotation angle of the one locking lever 8.

In this way, even if the handle bar 14 is slightly rotated, the first locking lever 8 of the rear side (or the front side) is not rotated, and thus the notch and the locking projections of any one of the first and second sets of the first locking levers 8 It is not abolished because it is in a state of engagement with 5).

At the time of closing, the handle bar 14 is operated, and the lower part of the handle bar 14 is brought into contact with the projection 8a of the first locking lever 8 to release the first locking lever 8 (Fig. 8 (b)). Rotating more than the backlash in the counterclockwise direction), the second locking lever 11 is rotated and the second notch (9) falls off the locking projection (5) of the leg (2) can be closed. .

As shown in Fig. 10, this wallpaper caller operates the handle bar 14 in the open state to rotate the lock lever 18 in the release direction (counterclockwise in Fig. 10 (b)), so that the first notch 6 Is released from the locking projection 5 of the leg 2, and the lock is released. In this state, the leg 2 can be rotated about the supporting shaft 4 (point of the upper end) by hand and closed (Fig. 10 (b). ), (c), (d)].

Then, when the leg 2 is completely closed, the second notch 9 becomes engageable with the locking projection 5 of the leg 2 (see Fig. 10 (e)).

In this state, the locking lever 18 is rotated in the locking direction (clockwise in Fig. 10 (f)) by the force of the spring member 7a, and the second notch 9 is the locking projection of the leg 2 ( In conjunction with 5), the leg 2 is locked in a closed state (see Fig. 10 (f)).

In addition, when opening, the lock lever 18 is rotated in the release direction (counterclockwise in FIG. 10 (e)) by operating the handle bar 14 to allow the second notch 9 to engage with the locking projection of the leg 2. The lock is released from 5) (see Fig. 10 (d)).

The leg 2 can be rotated and opened in this state (refer FIG. 10 (d), (c), (b)).

The locking lever 18 is rotated in the locking direction (clockwise in Fig. 10 (a)) by the force of the spring member 7a in the state where the leg 2 is completely open, and the first notch 6 is the leg. In conjunction with the locking projection 5 of (2), the leg 2 is locked in an open state (see Fig. 10 (a)).

Fig. 11 is provided with a spring 15 (loading means) for biasing the leg 2 in the closed angle direction in the wallpaper pawler of the fourth embodiment of the present invention. This spring 15 hangs one end to the pin 16 provided in the frame 1 side, and the other end hangs to the pin 17 provided in the front end side rather than the locking projection 5 of the leg 2. As shown in FIG.

The opening and closing operation of the leg portion of the wallpaper caller is basically the same as that of the fourth embodiment described with reference to Fig. 10, but for example, the leg 2 is provided by providing the spring 15 which biases the leg 2 in the closed angle direction. ) Can be unlocked to prevent the legs (2) from unintentionally and forcefully opening their own weight when the wallpaper caller is getting out of the car, and to prevent the operation. The action of the spring 15 in this case is the same as that described in the modification of the first embodiment.

[Fifth Embodiment]

In the fourth embodiment described above, four sets of locking mechanisms including locking levers 18 are provided for each of the four legs 2 in front, back, left, and right to lock the wallpaper caller in the open state or the closed state.

When the wallpaper caller is in the open state, the locking lever 18 may rotate when an operator's hand accidentally touches or touches an object from one of the front and rear locking levers 18. This rotation is also transmitted to the lock lever 18 on the opposite side through the handle bar 14, and rotates the front and rear lock levers 18 to engage the locking projection 5 of the first notch 6 and the leg 2 with each other. In this case, the lock is released and closed, and the wallpaper callout is inclined or inverted.

Thus, in the fifth embodiment, the handle bar 14 is moved relative to the lock lever 18 in order to reduce the rotation of one locking lever 18 from being transmitted to the other lock lever 18 through the handle bar 14. Install with backlash.

As shown in FIG. 12, when attaching the handle bar 14 to the lock lever 18, two pins 18a are provided on the lock lever 18, and the blood bar 14c and blood circulation D 14d), the two pins 18a of the locking lever 18 are fitted to each other so that the handle bar 14 is backlashed with respect to the locking lever 18, and is mounted. In addition, both of the holes drilled in the handle bar 14 may be long holes.

Unexpectedly the worker's hand or object touches the locking lever 18 of any one of before and after, and the locking lever 18 is rotated, and the notch 6 of the locking lever 18 of the one side is locked. Since the backlash is present between the handle bar 14 even if it rotates away from the handle bar 14, even if the handle bar 14 does not rotate or the handle bar 14 rotates slightly, the rotation angle of the lock lever 18 is rotated. Smaller than the angle

In this way, even if the handle bar 14 is slightly rotated, the locking lever 18 on the opposite side is not rotated, so that the lock between the notch 6 and the locking projection 5 of either set of front and rear two sets of locking levers 18 is prevented. Even if it is released, since the engagement state between the notch 6 and the locking projection 5 of the other set of lock levers 18 is maintained, there is no closure.

When closing, operate the handle bar 14 to rotate the locking lever 18 in the release direction beyond the backlash. Both locking levers 18 rotate and the first notch 6 rotates the locking projections of the legs 2. 5) The lock is released and can be closed.

Although the example which showed embodiment mentioned above was demonstrated, this invention is not limited to this, It can implement in various aspects.

The wallpaper caller according to the present invention may be composed of two locking levers interlocking locking levers for fixing the legs in the open state and the closed state, whereby the first notch and the second notch are respectively opened and closed. It can be configured to engage almost at right angles with the ground protrusion, and the locking can be further secured.

In addition, the wallpaper caller of the present invention can securely lock the legs in the open state and the closed state, respectively, and can further lock or unlock the legs by the rotation operation of one locking lever. Easy to open and close the legs when transporting on the back.

Furthermore, the wallpaper caller of the present invention is provided with a urging means for urging the leg in the closed angle, for example, by releasing the lock to prevent the leg from being unintentionally strongly opened when the wallpaper caller is pulled out of the car. It can be configured so that no disturbance occurs.
