Description

[Technical Field]

[0001] This invention relates to a pen holder that is easy to take out and store. [Background technology]

[0002] A pen holder is useful when you are doing work that requires you to frequently pick up and put down a pen. Pen holders of various shapes have been devised to make it easy to take out and store pens.

[0003] Patent Document 1 describes a pen holder that stores pens in a cylindrical tube.

[0004] Patent Document 2 describes a pen stand that stores pens in a storage section having a substantially polygonal cross section. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 7680801

[0006] [Patent Document 2] Patent No. 6630018 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the pen storage compartment of the pen holder described in Patent Document 1 has a cylindrical structure as shown in Figure 16, which poses the problem that the pen must be moved up and down in order to remove the stored pen and move it to the writing position.

[0008] The device described in Patent Document 2 has a storage compartment with a depth of about 15 mm, which makes it somewhat easier to remove the pen, but it still does not solve the problem of having to move the pen upwards to remove it from the pen holder.

[0009] The pen needs to be moved up and down each time it is taken out and put away, which reduces the ease of writing. [Means for solving the problem]

[0010] The present invention is a pen stand comprising a nib holder (2) for holding a nib, a pen shaft holder (3) for holding a pen shaft, and a bottom portion (4), wherein the nib holder (2) is installed on the bottom portion (4), and the pen shaft holder (3) is installed on the bottom portion (4) opposite the nib holder (2) or connected to a support structure (41) extending from the nib holder (2), wherein the nib holder (2) is provided with a front recess (6) for holding the nib, and the pen shaft holder (3) is provided with a rear recess (7) for holding the pen shaft, and wherein at least one opening (5) is provided between the nib holder (2) and the pen shaft holder (3). [Effects of the Invention]

[0011] The pen holder of the present invention eliminates the need to move the pen up and down, which was previously necessary to take out and store pens in a pen holder, improving the efficiency of taking out and putting in pens.

[0012] Compared to conventional pen holders, this reduces the time required to insert and remove a pen by approximately two seconds, which has the effect of eliminating many wasted movements for users who frequently write with a pen. For example, for a user who writes 100 times a day, 240 days a year, this would reduce wasted time by 13.3 hours per year. The time saved could be allocated to promoting industrial development.

[0014] An embodiment of the present invention will be described with reference to the drawings. [Example]

[0015] A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing the configuration of the pen stand of the first embodiment, and FIG. 2 is a diagram showing the pen stand with pens stored therein. 3 and 4 are diagrams for explaining the dimensions and angles of each part. The pen tip holder 2 and the pen shaft holder 3 are connected at the bottom 4. The pen tip holder 2 has a front recess 6 for holding the pen tip, and the pen shaft holder 3 has a rear recess 7 for holding the pen shaft. An opening 5 is provided so that the pen 1 can be removed sideways without moving it up and down. An anti-slip mechanism 8 is provided under the bottom surface portion 4. The opening 5, the front recess 6 and the rear recess 7 are the main components of the present invention.

[0016] The pen stand of Example 1 is made of resin. To stabilize the center of gravity of the entire pen when the pen 1 is stored tilted as shown in Figure 2, a brass block is placed inside the pen tip holder 2 to make the front heavier. The pen shaft holder 3 was thin and tilted to reduce interference with the fingers when gripping the pen 1. The tilt angle K of the pen shaft holder was set to 78°. The size of the bottom surface portion 4 was 43×25 mm and 2 mm high. The size of the pen tip holder 2 was 25 x 25 x 25 mm. The pen shaft holder 3 has a width of 14 mm and a height of 28 mm. The gap between the pen tip holder 2 and the pen shaft holder 3 was set to 13 mm at the narrowest distance at the bottom. The pen holder weighs 77g.

[0017] Considering the stable holding and ease of removal of the pen 1, the front recess 6 that holds the pen tip is triangular in shape, with a depth C of 3 mm and a recess angle M of 140°. The rear recess 7 that holds the pen shaft is trapezoidal in shape, with the pen shaft supported at two points by two surfaces set at a recess angle N = 90°. With this structure, when storing the pen 1 in the pen stand, if you release your hand from the pen 1 between the front and rear holding parts, the pen tip and pen shaft will naturally fit into the center of the front recess 6 and the rear recess 7.

[0018] The horizontal distance A between the opposing front recess 6 and rear recess 7 was set to 24 mm, and the vertical distance B was set to 28 mm. With these dimensions, the pen holding angle L when storing a pen with a shaft diameter of 10 mm is 57°, which reduces the amount of pen angle adjustment required when moving the pen for storage and writing.

[0019] An example of use, effect, and utility of the first embodiment will be described. In tasks that require frequent pen changeover, such as desk work that involves repeatedly operating a computer keyboard and writing with a pen, or measurement work that involves measuring part dimensions with a vernier caliper and recording the dimensions on paper, the pen holder of this device is placed near the writing position (e.g., on top of the paper).

[0020] When using a conventional pen stand such as that shown in Figure 16, the pen must first be moved upward to remove it from the tube, and then moved to the writing position. However, with the pen stand of this invention, the pen can be removed sideways, eliminating the need to move the pen upward. Furthermore, the amount of pen angle adjustment required is minimal, reducing the operation time from removing to storing the pen by approximately 2 seconds. Assuming a user writes with the pen 100 times a day, 240 days a year, this would result in a reduction in wasted motion of 2 x 100 x 240 = 48,000 seconds / year = 13.3 hours / year. Furthermore, since there is no need to move the pen downwards when storing it, there is no risk of the pen hitting the bottom of the pen stand and damaging the tip, allowing the pen to be used for a longer period of time.

[0021] In the first embodiment, two openings 5 ​​are provided so that the pen can be inserted and removed in either direction, but the present invention can be realized with at least one opening.

[0022] A typical ballpoint pen is about 150mm long and weighs between 10g and 30g. In the size of Example 1, it is preferable that the weight of the pen stand is 70 g or more, since this stabilizes the center of gravity. If the size of Example 1 were made entirely from resin or a light metal such as aluminum, the weight would be insufficient and the center of gravity would become unstable when the ballpoint pen is stored, so it would be necessary to make part or all of the pen tip holding portion 2 heavier by using a metal material. In Example 1, a weight of 77g was achieved by combining resin and brass.

[0023] If the vertical distance B of the rear recess 7 is too short, the pen 1 will be held unstably, and if it is too long, the pen shaft holding part 3 will get caught between the thumb and index finger when gripping the pen 1, making it difficult to remove the pen. For these reasons, the vertical distance B of the recess should be between 20 and 40 mm.

[0024] The dimensions, angles, and materials of each part shown in Example 1 are examples and can be changed in consideration of center of gravity stability and operability. For example, the main role of the pen tip holder 2 is to stabilize the center of gravity of the pen stand, and it may be larger as long as it does not interfere with the writing task and other tasks. It is possible to achieve both a small size and a required weight by using a relatively heavy metal material such as iron or brass in each part. Of course, the entire structure may be made of metal.

[0025] A front recess angle M of 120° to 150° is convenient, but there is no limit to this angle, and it is up to the embodiment whether to prioritize a sharp angle for stable pen holding or an obtuse angle for ease of removal. Since the part of the front recess 6 that is involved in holding the pen tip is only the lowest part, the shape and angle of the part above that is not important. The nib of a typical ballpoint pen is made of iron or nickel and is magnetic, so magnetic force can be used to assist in holding the nib, for example, by attaching a magnetic sheet to the front recess 6 or by placing a magnet inside the nib holding portion 2. It is also possible to provide a recess at the corner of the front recess 6 and the bottom surface 4 where the pen tip comes into contact, thereby increasing the stability of the pen tip's holding or slightly raising the pen tip.

[0026] The shape of the rear recess 7 is trapezoidal, but it can also be triangular or arc-shaped as long as it holds the pen shaft and does not move toward the open section. However, if it is arc-shaped, the pen will not be held securely if there is only one contact point with the pen. Also, the thicker the rear, the more interference there is with the fingers when gripping the pen, making it difficult to remove.

[0027] The pen holding angle L is preferably 50 to 70°, but may be any other angle. The anti-slip mechanism 8 on the bottom surface depends on the slipperiness of the surface of the desk or the like on which the present invention is installed, so it does not have to be provided if it is not slippery. All surfaces other than the pen shaft holding portion 3 are vertical, but of course they may be angled instead of vertical. The thickness of the bottom part 4 is set to 2 mm, but since the pen tip moves up and down by this thickness when taking out and putting away the pen, it is preferable that this thickness be as thin as possible while maintaining the structural strength. For example, if a stainless steel plate is used, 0.5 mm is sufficient. [Example]

[0028] A second embodiment of the present invention will be described with reference to FIG. The pen stand of Example 2 has a structure in which the center of gravity of the pen stand is stabilized and the pen stand is less likely to tip over sideways by providing a horizontally extendable bottom plate 21. In exchange for the increased resistance to tipping, it is possible to reduce the size and weight of the pen tip holder 2. [Example]

[0029] A third embodiment of the present invention will be described with reference to FIG. The pen stand of Example 3 has a structure in which the center of gravity of the pen stand is stabilized and the pen stand is less likely to tip over backwards by providing a rearward extending bottom plate 31. In exchange for the increased resistance to tipping, it is possible to reduce the size and weight of the pen tip holder 2. [Example]

[0030] A fourth embodiment of the present invention will be described with reference to FIG. The pen stand of Example 4 has a structure in which the pen tip holder 2 is connected to the pen shaft holder 3 by a support structure 41 extending from the pen tip holder 2 . In this embodiment, the direction in which the pen can be removed is limited to one direction, but there is less interference between the middle finger and the pen shaft holder 3 when gripping the pen, making it easy to use. [Example]

[0031] A fifth embodiment of the present invention will be described with reference to FIGS. FIG. 8 is a perspective view of the pen stand of the fifth embodiment. 10 and 11, the front and rear holding sections are divided into two, and the pen shaft holding section bottom plate 52 moves in one direction on the slide guide 51. As part of the pen shaft holding section bottom plate 52 moves while remaining housed in the slide insertion section 53, the pen shaft holding section bottom plate 52 does not come off upward. By appropriately adjusting the dimensions of the slide guide 51, the pen shaft holding portion bottom plate 52, and the slide insertion portion 53, the position can be adjusted and fixed with just the right amount of resistance. This configuration allows the horizontal distance A of the recess shown in FIG. 9 to be adjusted, and the pen holding angle L can also be adjusted accordingly. 8 and 9 show an example in which the horizontal recess distance A is set to 30 mm.

[0032] When the vertical recess distance B of the rear recess 7 is 28 mm and the pen shaft diameter is 10 mm, the relationship between the horizontal recess distance A adjusted by this mechanism and the pen holding angle L is as shown in Table 1.

[0033] [Table 1]

[0034] The pen holding angle can be adjusted to the most comfortable angle for each user, maximizing the efficiency of pen removal and storage operations. [Example]

[0035] A sixth embodiment of the present invention will be described with reference to FIG. In the pen stand of Example 6, the shape of the pen tip holder 2 is changed to a curved shape 61 . There are no restrictions on the shape of each part as long as it does not interfere with lateral removal of the pen, holding the pen, or stabilizing the center of gravity. [Example]

[0036] A seventh embodiment of the present invention will be described with reference to FIGS. FIG. 13 is a perspective view of the seventh embodiment. The device has a simple shape including an open section 5, a front recess 6, and a rear recess 7 as components of the device. The shape is easy to process by cutting from a metal block or by combining general-purpose parts. For example, if the shape shown in Figure 14 is made from brass, the weight will be 147g, and the center of gravity will be stable enough. [Example]

[0037] An eighth embodiment of the present invention will be described with reference to FIG. The pen stand of Example 8 is provided with an adhesive mechanism 81 on the bottom surface so that it can be adhesively fixed in place. The bonding mechanism may be any method, including adhesive, adhesive tape, or magnetic bonding. When installing a pen stand with this mechanism, it is no longer necessary to make the pen tip holder 2 heavy to stabilize the center of gravity as in Examples 1 to 7, and the size of the pen tip holder 2 can be made as small as possible, as shown in FIG. In particular, when using this pen stand on a desk or workbench made of iron, it is effective to use it in the form of this embodiment in which a magnetic sheet is used for the adhesive mechanism 81.

[0038] As explained above, according to the present invention, the pen can be removed from the pen stand horizontally and moved to the writing position without moving the pen up and down and with minimal re-tilting of the pen. Compared to conventional pen holders, this reduces the time required to insert and remove a pen by approximately two seconds, which has the effect of eliminating many wasted movements for users who frequently write with a pen. For example, for a user who writes 100 times a day, 240 days a year, this would reduce wasted time by 13.3 hours per year. The time saved could be allocated to promoting industrial development.
