Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper gluing machine, and in particular, from a frame that supports a gluing machine main body, and a pedestal that is attached to the four corners of the frame and whose upper end is pivotally supported so that it can be opened and closed in the frame longitudinal direction In the wallpaper pasting machine provided with the leg portion, the opening and closing operation of the leg is easy, and the leg can be reliably locked in the open leg state and the closed leg state.

  As shown in the side view of FIG. 13, the wallpaper pasting machine includes a pasting machine main body A including a glue box, a group of rollers including a pasting roller and a feeding roller, and a leg B. And the leg part B is comprised with the flame | frame which supports the gluing machine main body A, and the leg 6 provided in the four corners of a flame | frame, it is longitudinal direction so that it may not become bulky when carrying a wallpaper gluing machine with a motor vehicle etc. It is comprised so that the leg part B can be folded inside.

  As a means for locking the leg B in the open leg state when the wallpaper pasting machine is used, there are conventionally known ones configured to be fixed with a knob bolt or a snap lock. However, the conventional fixing means have problems such as stability but troublesome opening / closing leg work, and conversely, work is easy but lacks stability.

  Therefore, for example, a lock member is provided that contacts the side surface of the leg on the base side from the pivotal fulcrum of the pedestal when in the open leg state and is biased by the biasing means to lock the leg in the open leg state. Has been proposed (see Patent Document 1 below).

  Further, in such a structure in which the lock member abuts on the root side from the rotation fulcrum of the leg, an extension part for abutting the lock member on the upper side (base side) from the rotation fulcrum of the leg is provided. Since the part protrudes outward from the pivotal fulcrum with the legs closed, the width of the gluing machine is increased by that amount (if the distance between the legs is constant). The upper end of the leg is pivotally supported on the supporting member, a locking projection is provided below the pivoting fulcrum of the leg, and a locking means for engaging the locking projection of the leg is attached to the supporting member. Accordingly, there has also been proposed a work that is easy to work, stable, and has a shortened external dimension of the gluing machine, particularly in the width direction (see Patent Document 2 below).

A stopper that prevents the leg from rotating is provided at a position away from the pivot point of the leg, and a stopper guide that locks the leg stopper in the open leg state and the closed leg state is provided on the leg holding member. A leg support structure for a wallpaper pasting machine has been proposed (see Patent Document 3 below).

  However, the conventional wallpaper pasting machine has a lock that abuts against the side of the leg at the base side from the pivoting fulcrum of the leg when in the open leg state, and is biased by the biasing means to lock the leg in the open leg state. In the case where the member is provided, as described above, there is a problem that an extension part is necessary on the base side from the pivoting fulcrum of the leg, and that part protrudes outside in the closed leg state. In addition, since the base side is locked, there is a problem that the stress is increased when an external force is applied from the side, and the locked state is not stable.

  In addition, the upper end of the leg is pivotally supported on a support member provided on the frame, a locking projection is provided below the pivot support point of the leg, and the locking projection is engaged with the support member. In the case where the locking means is attached, as described above, the work is easy and stable, and the size in the width direction of the gluing machine does not increase with the opening and closing of the legs. There are problems to be solved, such as a relatively small distance between the stopping projection and the pivotal fulcrum of the leg, a large force is easily applied to the locking means, and damage or rattling may occur.

  The present invention has been conceived to solve such a problem, and provides a wallpaper pasting machine that can easily open and close the legs and can securely lock the legs in the opened and closed legs. The purpose is to do.

The wallpaper pasting machine according to the present invention includes a frame configured by a square pipe having a square cross-sectional shape and supporting the pasting machine body, and an upper end pivotally supported at the four corners of the frame so that the legs can be opened and closed in the longitudinal direction of the frame. In a wallpaper pasting machine with legs made of
A rod member that has a hole through which a pin is inserted at one end, and the other end is pivotally supported in a portion away from the upper end supported by the leg,
A groove is formed over the entire length on the upper surface in the longitudinal direction, a slit in the longitudinal direction in which the rod member slides is formed in the middle portion, and a hole formed in one end portion of the rod member on both side surfaces in the longitudinal direction. An assembly block that is inserted from both ends of a rectangular pipe in the longitudinal direction that constitutes the frame;
A pin that is fitted in the groove of the assembly block and is pivotally supported so as to be tilted, and is inserted into a hole at one end of the rod member, and a second recess that fits in a closed leg state and a second leg that fits in an open leg state. A recess is formed, and a leg locking mechanism including a lock lever on which the pin slides by the elasticity of a spring is provided.

  According to the wallpaper pasting machine of the present invention, the lock lever for fixing the leg in the open leg state and the closed leg state can be constituted by one lock lever, and the first concave portion and the second concave portion are the open leg. It can be configured to be engaged with the pin of the bar member when the leg is closed and when the leg is closed, and the lock can be further ensured.

  Further, the wallpaper pasting machine of the present invention can securely lock the legs in the open leg state and the closed leg state, and can lock or unlock the legs by rotating one lock lever. Since inadvertent opening and closing of the legs can be prevented, for example, it is easy to open and close the legs when loading and unloading the wallpaper pasting machine in an automobile or the like.

(First embodiment)
The wallpaper pasting machine according to the first embodiment includes a pasting machine body A including a glue box, a group of rollers such as a pasting roller and a feed roller, and a leg B. As shown in FIG. 13, the pasting machine main body A has a conventionally known configuration. Further, the leg B includes a frame for supporting the gluing machine main body A, a leg 6 having an upper end rotatably supported by a support shaft on leg support members 5 provided at four corners of the frame, and the leg And a leg lock mechanism that locks the leg 6 in the open leg state or the closed leg state, and the leg 6 can be folded inside the frame.

  As shown in the front view of FIG. 2, the plan view of FIG. 3, and the side view of FIG. 4, the frame 4 is formed by four square pipes 41, 42 having a square cross section. A leg support member 5 having a leg is fixed, and a support shaft 51 of the leg support member 5 is inserted into a hole in the upper part of the leg 6 to pivotally support the leg 6 (see FIG. 1).

  As shown in a bottom view (a) and a side view (b) of FIG. 5, the rod member 3 of the leg lock mechanism is formed on the lower surface of both end portions of the square pipe 41 having a rectangular cross section constituting the frame 4. A sliding slit 43 is formed.

  As shown in the longitudinal sectional view of FIG. 1, the leg lock mechanism includes an assembly block 1 made of a synthetic resin inserted from openings at both ends of a square pipe 41 in the longitudinal direction constituting the frame 4, a lock lever 2, And the bar member 3.

  As shown in FIG. 6, the lock lever 2 is formed with a downward projection 21 that engages with a coil spring 16 (see FIG. 1) at the tip, and an upwardly facing inclined surface 24 adjacent to the projection 21. An open first recess 22 is formed, and an upwardly opened second recess 23 is formed with an inclined surface 25 in the middle, and the lock lever 2 is interposed between the second recess 23 and the rear end. A shaft hole 26 for tilting is supported, and an operation handle bar 7 (see FIGS. 1 and 3) is coupled to the rear end portion using a hole 28.

  At the upper end of the rod member 3 of the leg lock mechanism, a hole 32 is formed through which a pin 31 that slides on the upper surface of the lock lever 2 and the lateral slot 14 (see FIG. 7) of the assembly block 1 is inserted. The lower end of the leg 6 is rotatably connected to an intermediate part away from the upper end where the leg 6 is pivotally supported 61 by the support shaft 51 by a connecting pin 62.

  As shown in the front view (a), plan view (b), bottom view (c), side view (d), and (e) of FIG. A groove 11 into which the lock lever 2 is fitted is formed almost over the center line, and a longitudinal slit 12 in which the bar member 3 slides at a position deviating from the longitudinal center line at the intermediate portion. A bottomed hole 13 into which a coil spring is fitted is formed in the vicinity of the end of the groove 11. However, the upper part of the bottomed hole 13 forms a part of the groove 11.

  Further, as shown in the front view (a) of FIG. 7, lateral slits 14 in which the pins 31 inserted through the holes 32 at the upper end of the rod member 3 slide are formed in the front and rear surfaces of the assembly block 1. And a hole 15 through which a pin 27 for tiltably supporting the lock lever 2 is inserted. The length of the pin 31 inserted through the hole 32 at the upper end of the bar member 3 and the length of the pin 27 that supports the lock lever 2 so as to be tiltable are substantially the same as the width of the assembly block 1. When the assembly block 1 is inserted into the square pipe 41, both ends of the pin 31 and the pin 27 are sealed by the inner surface of the square pipe 41, so that they do not come out.

  Next, the assembly procedure of the leg lock mechanism in the wallpaper pasting machine configured as described above will be described.

  The coil spring 16 is fitted into the bottomed hole 13 of the synthetic resin assembly block 1 and the lock lever 2 is fitted into the groove 11 while the downward projection 21 of the lock lever 2 is aligned with the coil spring 16. The pin 27 is inserted into the shaft hole 26 of the lock lever 2 through the hole 15 formed in the assembly block 1, and the lock lever 2 is tiltably supported.

  The rod member 3 is inserted from the bottom along the side of the lock lever 2 already fitted through the longitudinal slit 12 of the assembly block 1, and the lock lever 2 is pushed down against the elasticity of the coil spring 16. The pin 31 is inserted into the hole 32 in the upper end portion of the bar member 3 through the lateral slit 14 of the assembly block 1 and the upper surface of the lock lever 2. The inserted pin 31 slides on the upper surface of the lock lever 2 and the inner surface of the lateral slit 14.

  In this way, four sets of lock assemblies in which the lock lever 2 and the bar member 3 are assembled in the assembly block 1 are inserted from the open ends of the four corners of the square pipe 41 constituting the frame 4.

  As shown in FIG. 5, since the slits 43 on which the bar member 3 slides are formed in advance on the lower surfaces of both ends of the square pipe 41, the bar member 3 can be suspended from the square pipe 41. A screw is screwed into the hole 17 of the assembly block 1 from the hole on the front surface of the square pipe 41 to fix the assembly block 1.

  As shown in FIG. 4, a leg support member 5 having an L-shaped cross-section formed at the upper part of one surface of the slit 52 where the end of the lock lever 2 moves up and down is attached to the four corners of the frame 4. By attaching the leg support member 5, the end of the square pipe 41 can be closed and the end of the lock lever 2 can be projected from the slit 52.

  The unlocking bar 7 is attached using the holes 28 of the two front and rear lock levers 2 protruding from the end of the square pipe 41 (see FIG. 4).

  Next, the leg opening operation of the wallpaper pasting machine configured as described above will be described.

  In the closed leg state, as shown in FIG. 8A, the pin 31 of the rod member 3 is engaged with the first recess 22 of the lock lever 2, and the protrusion 21 at the tip of the lock lever 2 is moved by the coil spring 16. Since it is pushed up, the leg 6 is locked in a closed state.

  As shown in FIG. 8 (b), when the unlocking bar 7 is pulled up against the elasticity of the coil spring 16, the pin 31 of the bar member 3 and the first recess 22 of the lock lever 2 are engaged. Comes off.

  By releasing the engagement, the pin 31 of the bar member 3 can slide in the slit 14 of the assembly block 1, so that when the frame 4 is lifted as shown in FIG. The connected leg 6 starts to open due to its own weight and passes through the state shown in FIG. 8D, and the pin 31 of the bar member 3 reaches the inclined surface 25 of the lock lever 2 as shown in FIG. 9E. .

  Thus, when the pin 31 reaches the inclined surface 25, the rod member 3 must be pulled with a large force in order for the pin 31 to push down the inclined surface 25 of the lock lever 2 against the elasticity of the coil spring 16. Therefore, a resistance force acts on the leg opening operation of the leg 6, and the leg opening speed temporarily decreases.

  9 (f), when the pin 31 of the rod member 3 pushes down the inclined surface 25 of the lock lever 2 and exceeds the inclined surface 25, the pin of the rod member 3 is moved as shown in FIG. 9 (g). 31 engages with the second recess 23 to lock in the open leg state.

  Next, the leg closing operation of the wallpaper pasting machine will be described.

  In the open leg state, as shown in FIG. 10A, the pin 31 of the rod member 3 is engaged with the second recess 23 of the lock lever 2, and the protrusion 21 at the tip of the lock lever 2 is the coil spring 16. The leg 6 is locked in the open leg state.

  As shown in FIG. 10B, when the lock release bar 7 is pulled up against the elasticity of the coil spring 16, the lock lever 2 rotates and the pin 31 of the bar member 3 and the lock lever 2 The engagement with the second recess 23 is released.

  By releasing the engagement, the pin 31 of the bar member 3 can slide in the slit 14 of the assembly block 1, so that the leg 6 connected to the bar member 3 can be moved as shown in FIG. When closed, the pin 31 of the bar member 3 reaches the inclined surface 24 of the lock lever 2 as shown in FIG. 11 (e) through the state shown in FIG. 11 (d).

  Thus, even if the pin 31 reaches the inclined surface 24, the angle formed by the slit 14 of the assembly block 1 and the bar member 3 becomes an acute angle, so that the pin 31 resists the elasticity of the coil spring 16. However, a large force is not required for the bar member 3 to push down the inclined surface 24 of the lock lever 2.

  After the state shown in FIG. 11 (f), when the pin 31 of the bar member 3 pushes down the inclined surface 24 of the lock lever 2 and exceeds the inclined surface 24, as shown in FIG. 31 engages with the first recess 22 and locks in the closed leg state.

(Second Embodiment)
In the first embodiment described above, the protrusion 21 at the tip of the lock lever 2 is formed downward, and the first recess 22 and the second recess 23 open upward. In the second embodiment, 12, even when the arrangement of the lock lever 2 and the assembly block 1 is turned upside down, the operation direction of the unlocking bar 7 is downward when releasing the lock in the closed leg state or the open leg state. However, it can be operated in the same manner as in the first embodiment.
