Description

[Technical field]

[0001] The present invention relates to a wallpaper pasting machine, and more particularly to the attachment and detachment of a wallpaper cutting device to be mounted on a wallpaper pasting machine. [Background technology]

[0002] Conventionally, automatic wall pasting machines and manual wall pasting machines have been known as wallpaper pasting machines, and wallpaper cutting devices that are detachably provided on these pasting machines are also known.

[0003] The applicant has also made various proposals, including an invention in which an automatic wallpaper gluer equipped with a wallpaper cutting device is provided with a stopper to prevent the wallpaper from falling off (Patent Document 1), an invention in which a locking part is provided on the upper hook of the wallpaper cutting device (Patent Document 2), and an invention in which the locking part at the bottom of the wallpaper cutting device is designed to absorb shock (Patent Document 3). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6541060 Public Relations

[0005] [Patent Document 2] Patent No. 6521516 Public Relations

[0006] [Patent Document 3] Patent No. 6617956 Public Relations Summary of the Invention [Problem to be solved by the invention]

[0007] The wallpaper pasting machine may be brought to the site where the wallpaper is to be pasted, or may be used in an office to paste the wallpaper and then carried away. The object of the present invention is to transport the wallpaper pasting machine to the site.

[0008] When loading the wallpaper pasting machine from the wallcovering craftsman's office into a car, when moving it from the car to the work site, or when moving the wallpaper pasting machine within the work site, the wallpaper cutting device can be moved while attached to the wallpaper pasting machine, or separated into the main body of the wallpaper pasting machine and the wallpaper cutting device, depending on the wallcovering craftsman's preference and the most convenient state for use.

[0009] The main body of the wallpaper pasting machine is equipped with detachable, foldable legs, and these legs are equipped with casters for mobility. Therefore, when there is some distance between where the car is parked and the installation site, it is normal to open the legs of the wallpaper pasting machine, put it in the usable state, and move it with the casters on the ground.

[0010] Although wall decorators can choose when to attach the wallpaper cutter and legs to the wallpaper gluer at their discretion, they often leave the wallpaper cutter and legs attached when loading the machine from the office into a car, but fold the legs when loading it, and then open the legs and move the machine from the car park to the construction site and within the construction site in the ready-to-use state.

[0011] When transporting or moving such a wallpaper pasting machine, the wallpaper cutting device may fall off the wallpaper pasting machine, causing damage to tools and materials inside the vehicle, or the frame of the wallpaper cutting device may be hit hard, causing damage.

[0012] Against this background, the applicant has filed applications such as those listed in Patent Documents 1 to 3 above.

[0013] The inventions in both Patent Documents 1 and 2 are intended to prevent the wallpaper cutting device from falling off; when the legs are folded and loaded into a car for transport and the car goes over a large step, or when the car is moving quickly over a step on a sidewalk or the like while in use with the legs open and the casters on the ground, the hook piece on the top of the wallpaper cutting device attached to the main body of the automatic wallpaper gluer abuts against a stopper provided on the stay of the automatic wallpaper gluer, or the stopper attached to the hook piece abuts against the stay of the automatic wallpaper gluer, preventing the wallpaper cutting device from falling off.

[0014] Furthermore, Patent Document 3 aims to prevent damage and deformation of the elastic clamping hook piece. By providing a groove and a shock absorbing part in the elastic clamping hook piece at the bottom of the wallpaper cutting device, when the automatic wallpaper pasting machine passes over a step on a sidewalk or the like with great force, the shock is absorbed when the step falls and the casters touch the ground, preventing damage and deformation of the hook.

[0015] As described above, the applicant has devised various inventions to prevent the wallpaper cutting device from falling off or being damaged when the wallpaper pasting machine is transported or moved. However, with these inventions, there are still cases where the wallpaper cutting device is damaged when a strong lateral force is applied during transportation or movement.

[0016] For example, in Patent Documents 1 and 2, when an impact occurs during transportation or movement of the automatic wallpaper pasting machine and the wallpaper cutting device attempts to float up, the hook piece 5 hits the wallpaper cutting device prevention stopper 10 attached to the upper stay 3 (Patent Document 1), or the fall prevention stopper 10 attached to the hook piece 5 hits the upper stay 2a (Patent Document 2), so that the hook piece 5 does not come off completely and returns to the lower stay 9.

[0017] However, because the hook piece 5 and the wallpaper cutting device removal prevention stopper 10, and the fall prevention stopper 10 and the upper stay (3, 2a) are not in close contact with each other, a vertical gap exists, and when a vertical impact is applied to the wallpaper cutting device simultaneously with a lateral impact, the elastic clamping hook piece comes off the lower pin body and the wallpaper cutting device floats up.

[0018] For example, when a wallpaper pasting machine in which stoppers 10 are provided on the upper stay 2a as shown in Figure 6 of the present application is subjected to vertical and horizontal impacts, causing the wallpaper cutting device to float up, the hook piece 5 will attempt to return to its attached state by abutting against the stoppers 10 on the upper stay 2a before the wallpaper cutting device comes off completely, but it does not necessarily return to its original position by following the same path as when it floated up, and there are cases in which the wallpaper cutting device returns in a slightly vertically floated state as shown in Figure 7, returning to a position that is different from the position in which the elastic clamping hook piece 7 fits into the lower pin body 8, and the elastic clamping hook piece 7 may crack and become damaged (Figures 6 and 7 show a state in which a stopper 10 is provided as in Patent Document 1, but the wallpaper cutting device also floats up in a similar manner in Patent Document 2).

[0019] In contrast to Patent Documents 1 and 2, in Patent Document 3, when vertical vibration occurs due to an impact such as a fall, the shock absorbing oscillating portion 823 oscillates vertically within the shock absorbing groove portion 822, thereby absorbing the impact and preventing damage or deformation of the elastic clamping hook piece (812).

[0020] Although the invention of Patent Document 3 is resistant to vertical vibrations, when a lateral force is applied and the invention moves to come loose, it floats up, just like Patent Documents 1 and 2, and the pin body and the elastic clamping hook piece may return to their original positions with the position shifted vertically, leaving the possibility that the elastic clamping hook piece may crack and break.

[0021] To provide a wallpaper pasting machine in which components will not break and be damaged when a wallpaper cutting device attached to the wallpaper pasting machine moves in such a way that it floats up and comes off due to an impact generated during transportation or movement, in consideration of the current situation. [Means for solving the problem]

[0022] An automatic wallpaper pasting machine comprising a pasting machine main body and a wallpaper cutting device, the pasting machine main body pasting wallpaper with a pasting roller, and the wallpaper cutting device cutting the wallpaper to a predetermined width prior to pasting, The wallpaper cutting device is configured so that it can be attached to a wallpaper pasting machine using a hook piece and an elastic locking part provided on the wallpaper cutting device, and the hook piece is configured so that it can be attached to the lower stay of the wallpaper pasting machine, and the hook piece is equipped with a slidable locking piece, and is configured so that when the locking piece slides, the upper tip of the hook piece expands and the lower stay of the wallpaper pasting machine is locked in a circular shape.

[0023] The hook piece has an arc-shaped guide portion on the upper side, and the locking piece has an engaging portion that can engage with the guide portion of the hook piece and slide, and the locking piece slides to the upper tip of the hook piece along the arc-shaped guide portion, thereby abutting and locking the upper part of the hook piece in an arc-shaped expanded state.

[0024] The lock piece is expanded in an arc shape to come into contact with the outer periphery of the lower stay at an angle of 210 degrees or more and lock. Effect of the Invention

[0025] According to the present invention, the hook piece of the wallpaper cutting device is locked in a circular shape to the lower stay of the wallpaper pasting machine, so that when an impact is applied to the wallpaper cutting device, the wallpaper cutting device describes an arc-shaped trajectory around the lower stay as an axis to dissipate the impact, and when returning to the mounting position, it follows the same trajectory, so that the lower pin body of the elastic clamping hook piece will not come into contact with a place where it should not be placed and the elastic clamping hook piece will not be damaged.

[0026] In addition, by expanding the locking piece in an arc shape, it comes into contact with the outer periphery of the lower stay at an angle of 210 degrees or more and locks, so as long as the locking piece is expanded, the hook piece will not come off the lower stay and float up.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. Example 1

[0029] The wallpaper pasting machine 1 is composed of a main body and legs and has a similar configuration to conventional pasting machines, and the configuration of the wallpaper cutting device is also approximately the same. Therefore, the attachment and detachment of the main body of the wallpaper pasting machine 1 and the wallpaper cutting device 4 and how to prevent them from falling off or being damaged will be explained using Figures 1 to 4.

[0030] Figure 1 shows the wallpaper cutting device 4 attached to the wallpaper pasting machine 1, Figure 2 shows the wallpaper cutting device 4 and the hook piece 5 extracted from the cutting device, Figure 3 shows the locking piece 6 of the hook piece 5 after it has been slid and expanded, and Figure 4 shows the wallpaper cutting device 4 being lifted up due to an impact being applied while the hook piece 5 is locking the lower stay 9.

[0031] First, the configuration of the present invention will be described. As shown in Fig. 1, an upper stay 2a is provided on an upper frame 2 of a wallpaper pasting machine 1, and a lower pin body 8 and a lower stay 9 are provided on a lower frame 3. A hook piece 5 and an elastic clamping hook piece 7 are provided on a wallpaper cutting device 4, and the upper part of the hook piece 5 of the wallpaper cutting device 4 is hooked onto the lower stay 9 of the wallpaper pasting machine 1, and then the elastic clamping hook piece 7 is fitted into the lower pin body 8 for installation.

[0032] As shown in Figures 2(a) and (b), the wallpaper cutting device 4 is equipped with a hook piece 5, which is provided with an arc-shaped guide portion 5a, and the engaging portion 6a of the lock piece 6 is slidably engaged with the guide portion 5a.

[0033] 2(a) when viewed from the side, the lock piece 6 is normally located in a position that fits within the outer diameter of the hook piece 5. The lock piece 6 can slide along the arc-shaped guide portion 5a, and by sliding toward the upper tip of the hook piece 5, it can exceed the tip of the hook piece 5 and expand the tip of the hook piece 5 in a circular shape.

[0034] Fig. 3 shows the state in which the locking piece 6 has been slid to its maximum extent in the direction of the upper tip of the hook piece 5. In this state in which the locking piece 6 has been slid to its maximum extent, it has a shape that extends beyond the upper tip of the hook piece 5 in a circular shape, and the hook piece 5 and the locking piece 6 come into circular contact with the lower stay 9 of the wallpaper glue applicator, enabling them to be locked.

[0035] When the hook piece 5 and the lock piece 6 are expanded into a circular shape, they abut against the lower stay 9 at a minimum of 210 degrees with respect to the outer periphery of the circle, with the center of the lower stay 9 being the center of the circle and the outer periphery of the lower stay 9 being the outer periphery of the circle.

[0036] Next, the installation of the wallpaper cutting device 4 will be described. The wallpaper cutting device 4 is installed by hooking the hook piece 5 onto the lower stay 9 of the wallpaper pasting machine body and then fitting the elastic clamping hook piece 7 into the lower pin body 8. Note that Figures 1 to 4 are side views, and in reality the hook piece 5 and the elastic clamping hook piece 7 are provided on the left and right sides of the wallpaper cutting device 4, so the left and right hook pieces 5 are hooked onto a single lower stay 9, and then the elastic clamping hook pieces 7 provided on the left and right sides of the wallpaper cutting device 4 are fitted into the lower pin bodies 8 provided on the left and right sides of the lower frame 3 of the pasting machine body. Up to this point, the method is the same as that for installing a conventional wallpaper cutting device 4 to a wallpaper pasting machine body.

[0037] Then, after the hook piece 5 and the elastic clamping hook piece 7 are attached to the lower stay 9 and the lower pin body 8, the lock piece 6 of the hook piece 5 is slid with a finger, and the tip of the hook piece 5 is expanded into a circular shape by sliding the lock piece 6 along the arc-shaped guide portion 5a.

[0038] By expanding the tip of hook piece 5 into a circular shape using lock piece 6 in this manner, hook piece 5 and lock piece 6 will cover and lock lower stay 9 by at least 210 degrees or more, leaving no room for the hook to move upwards; once the sliding of both lock pieces 6 provided on the left and right hook pieces 5 of wallpaper cutter 4 is completed, installation of wallpaper cutter 4 of the present invention is complete.

[0039] Next, we will explain how damage to parts is prevented by the action of the lock piece 6. When the lock piece 6 is slid to its maximum extent as shown in Figure 3, even if an upward force is applied to the hook piece 5 and lock piece 6 attached to the lower stay 9, the hook piece 5 and lock piece 6 lock the lower stay 9 in a circular shape, so the hook piece 5 will not come off the lower stay 9 and float up.

[0040] In this case, even if vertical and horizontal forces are applied to the wallpaper cutter 4 at the same time, the hook piece 5 will not come off and float up as shown in Figure 7. Instead, it will rotate in an arc around the center of the lower stay 9 as an axis as shown in Figure 4, allowing it to float up and absorb the impact.

[0041] Then, after dissipating the shock by rotating in an arc around the lower stay 9 as an axis, it follows the same trajectory and returns to the mounting position in FIG.

[0042] In other words, even if the elastic clamping hook piece 7 of the wallpaper cutting device 4 and the lower pin body 8 of the lower frame 3 are disengaged by impact, they always return to the same position when returning to the mounting position, and the lower pin body 8 always fits into the elastic clamping hook piece 7, so that the elastic clamping hook piece is not broken and damaged when the lower pin body 8 hits the elastic clamping hook piece 7 without fitting in as shown in Figure 7.

[0043] Although the method of sliding the lock piece 6 and fixing its position is not specifically described, various modifications are possible without departing from the scope of the invention, such as adjusting the resistance of the guide portion 5a and the engaging portion 6a, adjusting the shape of the guide portion 5a, or providing an additional member to fix it so that it does not slide.

[0044] In addition, although the guide portion 5a is shown in the drawing as a through hole, the guide portion may be provided as a groove on both sides of the hook piece 5, and may serve as a locking piece that slides through the groove, and various modifications are possible without departing from the scope of the present invention.

[0045] Another embodiment (Example 2) of the present invention will be described with reference to the drawings. Example 2

[0046] The configuration of a wallpaper pasting machine according to a second embodiment of the present invention will be described with reference to Fig. 5. Note that the same numbers are given to components with the same configuration.

[0047] In the wallpaper pasting machine 20 and wallpaper cutting machine 21 in the example boat 2, the hook piece 5 and lock piece 6 that engage with the lower stay 9 are the same as those in the example 1, and the installation method is also the same. On the other hand, the elastic clamping hook piece 7 is replaced with an insertion piece 22, and the lower pin body 8 is also replaced with a receiver 23.

[0048] In the second embodiment, the hook piece 5 and the lock piece 6 have the same structure, so when a vertical force and a horizontal force are simultaneously applied to the wallpaper cutter 21, the wallpaper cutter rotates in an arc around the lower stay 9 as an axis to dissipate the impact, and this movement is also the same.

[0049] When adopting a structure like this in which the lower stay 9 rotates around an axis to absorb shock, the hook piece and lock piece of the wallpaper cutting device are the main means of preventing falling off and damage, so in the second embodiment, instead of fastening with a pin body and clamping piece, the insertion piece 22 is fitted into the receiver 23 as shown in Figure 5 and fixed in place.

[0050] If the insertion piece 22 and the receiver 23 are made of magnets of different poles, the fixation when attached can be strengthened.

[0051] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these, and various modifications are possible without departing from the scope of the present invention. [Explanation of symbols]
