Description

[Detailed Description of the Invention] The present invention relates to a roll paper exchange frame, and more particularly to a roll paper exchange frame that can be easily attached to an existing paper holder and can be quickly replaced with a spare roll paper.

As a device for holding spare rolls of toilet paper, there is a holder 10 made of cloth, as shown in FIG. However, when this happens,
When the paper holder runs out of paper, it is troublesome to take out the spare roll paper from the holder 10 and attach it to the paper holder anew.

The inventor proposed the second method to solve the above problems.
As shown in the figure, a replacement frame 16 formed into an H shape by connecting side plates 12a and 12b at the center with a connecting rod 14 is prepared, and a roll paper 18 is placed on the upper and lower parts of the replacement frame 16. The replacement frame 16 is slidably and swingably supported on the support plate 22 of the paper holder 20, and when the upper roll paper 18 is used up, the replacement frame 16 is attached removably. He has devised and filed an application for a roll paper exchange frame in which the roll paper 16 is turned upside down so that the lower roll paper 18 can be positioned above.

However, the above-mentioned mechanism for freely sliding and swinging the replacement frame 16 is such that the exchangeable frame 16 can freely slide and swing within the guide groove 24 which has a T-shaped cross section and is provided on the outer walls of the side plates 12a and 12b of the replacement frame 16. A fixture 26 is provided which slides on the guide groove 24 and whose tip protrudes outward from the guide groove 24.
The tips of the paper holders 20 and 6 are fitted into blind holes provided in the inner wall of the support plate 22 of the paper holder 20 to be fixedly positioned, and the exchange frame 16 is provided so as to be relatively slidable and swingable. In this way, in the past, the replacement frame 1
Since the guide grooves 24 having a T-shaped cross section are provided on the side plates 12a and 12b of 6, the side plates 12a and 12b must be thick, with a thickness of at least 6 to 8 mm.

Therefore, the above-mentioned replacement frame body 16 has both sides plates 12
The total thickness of a and 12b is about 12 to 16 mm.

However, the width between the support plates 22 of the existing paper holder 20 is set wider than the width of the roll paper 18 in order to make it easier to replace the roll paper 18, but it is only about 15 mm wider. do not have.

Therefore, if the side plates of the replacement frame 20 alone are required to be as thick as 12 to 16 mm as described above, it becomes extremely difficult or impossible to attach the roll paper 18 to the replacement frame 16.

For this reason, conventionally, the above-mentioned exchange frame 16
The problem was that it had to be used in combination with a dedicated, larger paper holder.

Furthermore, in order to manufacture the replacement frame 20 cheaply and easily, it is preferable to integrally mold it from synthetic resin.
In this case, the guide groove 24 having a T-shaped cross section as described above is used.
It is troublesome to design the mold, and the side plate 1
Since 2 is thick, a large amount of resin material is required, which also has the drawback of increasing costs.

The present invention has been made in view of the above, and its purpose is to provide a roll paper exchange frame that can be easily attached to an existing paper holder and that can be formed at a low cost.
The feature is that two roll papers can be supported in two stages, upper and lower, using appropriate support rods, and the side plate 32
a, 32b are connected by a connecting rod 34 to form a substantially H-shaped frame, and guide holes 42, 42 extending vertically are provided in the outer walls of the side wall plates 32a, 32b, respectively. , the tip is the side wall plate 32a, 32
b Support 4 formed on a protruding shaft 46 projecting outward
4 are provided to be slidable and rotatable, respectively, and can be detachably attached to a suitable paper holder by means of the protruding shaft 46.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3, 4, and 5 show a front view, a side view, and a plan view of the exchange frame 30, respectively.

In the figure, 32a and 32b are side plates, which are connected at the center by a connecting rod 34 to form a substantially H-shaped frame.

The distance between the side plates 32a and 32b is determined based on the fact that the width of the standard roll paper 36 is approximately 115 mm.
It is formed to be wider than this at approximately 121mm. The side plates 32a and 32b are each formed to have a thickness of about 2 mm.

The upper and lower inner surfaces of both side plates 32a and 32b are formed into a thick part 38 having a total thickness of about 3 mm including the thickness of the side plates, and the thick part 38 has both ends of a roll paper support rod 40. A support hole is provided in which the support hole can be inserted.

Reference numeral 42 denotes a guide hole extending in the longitudinal direction of the center of the side plates 32a, 32b, and its vertical ends reach near the thick portion 38.

44, 44 are supports, and upper and lower protruding shafts 46,
48 protrude perpendicularly to the connecting portion 50 in opposite directions, and the overall shape forms a substantially Z-shape. The lower protruding shafts 48 of the supports 44, 44 are connected to the side plates 32a, 3.
It passes through the guide hole 42 of 2b, and a thin disk 52 is provided at the tip of the protruding shaft 48 to prevent it from coming off from the guide hole 42. Therefore, the replacement frame 30 is slidable on the protruding shaft 48 and the protruding shaft 48 is guided through the guide hole 42, so that the replacement frame 30 can be moved from one end of the guide hole 42 to the other with respect to the protruding shaft 48. It can be moved freely up to the end of the The disk 52 at the tip of the protruding shaft 48 is formed to have a thickness of about 1 mm. Also, the side plate 32a,
The base of the connecting rod 34 that connects the rods 32b is bifurcated (see FIG. 5) so as to straddle the guide hole 42, and allows the disk 52 to freely pass through.

Another protruding shaft 46 of the support 44 is a protruding shaft 48
comes into contact with the end of the guide hole 42, the side plate 32
The support holes provided in the thick portions 38 of a and 32b are set so that their axes coincide with each other.

The exchange frame 30 is supported by the paper holder 54 so that the protruding shaft 46 fits into a support hole 58 formed in the inner wall of the support plate 56 of the paper holder 54.

In this case, the support tool 44 can be easily fitted into the support hole 58 by pressing the side plates 32a, 32b with fingers or the like to bend them inward, and after fitting, the elasticity of the side plates 32a, 32b Tilt support tool 4
4 is suitably held in the support hole 58.

Note that the connecting portion 50 of the support 44 also has a thickness of approximately 1 mm.
It is formed with a moderately thin wall.

If necessary, the support 44 can be provided with a protruding shaft 46 that can be expanded and contracted by a spring 60, as shown in FIG. It becomes possible to hold the

In the present invention, since the guide holes 42 of the side plates 32a, 32b are formed as transparent holes, the side plates 32a,
32b can be formed as thin as described above. Therefore, the support plate 56 of the existing paper holder 54,
56 is approximately 15 times wider than the width of the roll paper 36.
Even if it is about 130 mm wide, it can be installed with plenty of room.

The distance between the upper and lower sides of the side plates 32a and 32b, on which the support rod 40 for the roll paper 36 is attached, is about 119 mm, which is about 4 mm, so there is no problem with the rotation of the roll paper 36. Moreover, the roll paper 36 can be easily replaced. Also, when used in this way, the support rod 40
exists, so even if the side plates 32a and 32b are formed thin as described above, no problem arises in terms of strength.

In addition to attaching the replacement frame 30 to the existing paper holder 54 as described above, the replacement frame 30 and paper holder 54 may be provided in any corresponding size and used as a set. This goes without saying.

In use, the roll paper 36 is fitted onto the upper and lower support rods 40, and when the upper roll paper 36 is finished, the exchange frame 30 is reversed toward the front around the protruding shaft 48, and the lower part is replaced with the roll paper 36. The roll paper 36 can be moved upward and used.

Also, when pulling out the paper during use, the support hole 58 of the support plate 56 of the paper holder 54, the protruding shaft 4
6. Since the support rods 40 are on the same axis, the replacement frame 30 will not swing due to the force of pulling out the paper.

Note that the support hole 58, the protruding shaft 46, and the support rod 40 do not necessarily have to be on the same line. In this case, as shown in FIG.
It is also possible to prevent the exchange frame 30 from swinging when paper is being pulled out by providing the exchange frame 30 in a substantially S-shape so that the S-shaped end comes into contact with the tray wall surface.

Note that the exchange frame 30 in the present invention can also be integrally molded (excluding the support) from synthetic resin.

As described above, the roll paper exchange frame according to the present invention can be easily attached to an existing paper holder and is economical, as well as being able to reduce the amount of resin and provide it at low cost. Effective.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
