[0006] The bed guard 11 of the aforementioned bed protection fence forming device 10 has the following points that need improvement. When fixing the upper horizontal support member 11b1 to the horizontal fixing member 11a in a predetermined position, a fixing device 11d (see also Figure 12A) as shown in Figure 13A is generally used. The fixing device 11d has a structure in which one end of a V-shaped metal leaf spring 11d3 is connected to a metal engaging projection 11d1, and the other end is connected to a metal vertical support member 11a.

[0007] Therefore, when fixing the upper horizontal support member 11b1 to a predetermined position on the vertical support member 11a due to the protrusion of the engaging projection 11d1 from the outer surface of the vertical support member 11a, the metal leaf spring 11d3 and the metal vertical support member 11a come into contact, resulting in an unpleasant, loud noise, which is a point that needs improvement.

[0008] Bed guards 11 and similar devices are often used on beds where newborns and infants sleep. Therefore, the unpleasant, loud noises caused by the fixing device 11d are particularly problematic because they could wake newborns and infants.

[0009] Therefore, the present invention aims to provide a fixing device that can prevent the generation of unpleasant, loud noises during the fixing process. [Effects of the Invention]

[0024] The fixing device according to the present invention will be described in detail below with reference to the drawings. The fixing device, a bed protective railing forming device, is attached to a bed to prevent a person sleeping on the sleeping surface of the bed from falling off the outer edge of the sleeping surface. [Examples]

[0025] Configuration of the first fixing device 100 The fixing device according to the present invention will be described using the fixing device 100 as an example. The fixing device 100 is used in a bed protective rail forming device BG that is attached to a bed and prevents a person sleeping on the sleeping surface of the bed from falling off the outer edge of the sleeping surface.

[0026] Here, the bed protective rail forming device BG will be explained using Figure 1. The bed protective rail forming device BG is positioned along the outer edge of bed B to prevent a person sleeping on the sleeping surface of the bed from falling off the outer edge of the sleeping surface. The bed protective rail forming device BG has a first protective rail forming part BG101 and a second protective rail forming part BG103. The first protective rail forming part BG101 is attached along outer edge E1 (see Figure 2), which is one of the outer edges that intersect at the corner of the sleeping surface PB3. The second protective rail forming part BG103 is attached along outer edge E3 (see Figure 2), which is the other outer edge that intersects at the corner of the sleeping surface PB3.

[0027] Generally, bed B has a bed base B1 and a mattress B3, as shown in Figure 2. The bed base B1 is located at a predetermined height from the floor. The mattress B3 usually has a predetermined thickness in the vertical, upward direction. The mattress B3 is placed on the bed base surface PB1 of the bed base B1. The user lies down on the sleeping surface PB3, which is the upper surface of the mattress B3.

[0028] The first protective fence forming section BG101 will be explained using Figure 3. Figure 3 shows the state after removing the mattress B3 from the bed B shown in Figure 1. The first protective fence forming section BG101 is placed on the floor surface PB1 of the floor board B1. The first protective fence forming section BG101 has a first vertical support section BG101a, a first horizontal support section BG101b, and a first side forming section BG101c.

[0029] The first vertical support portion BG101a is positioned to extend vertically upward from the floor surface PB1 of the bed base B1 of the bed B. Two of the first vertical support portions BG101a are positioned, corresponding to each of the two ends of the outer edge E1 of the mattress B3.

[0030] The first horizontal support section BG101b is positioned to suspend the first vertical support section BG101a, which is positioned corresponding to both ends of the outer edge E1 of the mattress B3. The first horizontal support section BG101b has an upper first horizontal support section BG101b1 and a lower first horizontal support section BG101b3. The upper first horizontal support section BG101b1 is positioned parallel to the lower first horizontal support section BG101b3 and vertically upward from the lower first horizontal support section BG101b3. The lower first horizontal support section BG101b3 is positioned along the sleeping surface PB3 of the mattress B3. The upper first horizontal support portion BG101b1 can move upward or downward along the vertical direction, along the first vertical support portion BG101a.

[0031] The first side forming portion BG101c is positioned along the outer edge E1 of the bed B. The first side forming portion BG101c is formed from a fibrous material such as fabric. The first side forming portion BG101c has a length approximately equal to the outer edge E1 of the bed B on which it is positioned, and a height between the upper first horizontal support portion BG101b1 and the lower first horizontal support portion BG101b3, which are positioned to suspend the first vertical support portion BG101a. The first side forming portion BG101c has a support portion arrangement portion whose outer edge is formed in a bag shape. By positioning the first vertical support portion BG101a or the first horizontal support portion BG101b inside the first support portion arrangement portion formed on the outer edge of the first side forming portion BG101c, the first side forming portion BG101c is attached to the first vertical support portion BG101a, the upper first horizontal support portion BG101b1, and the lower first horizontal support portion BG101b3.

[0032] Since the second protective fence forming section 103 has the same configuration as the first protective measure forming section 101, a detailed description is omitted.

[0033] Configuration of the second first vertical support section BG101a and the upper first horizontal support section BG101b1 The first vertical support portion BG101a and the upper first horizontal support portion BG101b1 will be explained with reference to Figure 4. Figure 4 shows the state in which the upper first horizontal support portion BG101b1 is fixed to a predetermined position on the first vertical support portion 101a near the upper end of the first vertical support portion 101a. Note that in Figure 4, the release portion of the upper first horizontal support portion BG101b1 is omitted. The release portion has a push button that presses the engaging projection 101 (described later) of the fixing device 100 (described later) arranged on the first vertical support portion BG101a in a direction from the outside to the inside of the first vertical support portion BG101a (direction of arrow a4).

[0034] Figure 5 shows a perspective view of one end of the upper first horizontal support portion BG101b1. The upper first horizontal support portion BG101b1 has a vertical support portion through hole BG101b1a and an engagement recess BG101b1b. The vertical support portion through hole BG101b1a is located at both ends of the upper first horizontal fixing portion BG101b1. The vertical support portion through hole BG101b1a is formed as an opening that penetrates the first vertical support portion BG101a (see Figure 4). The upper first horizontal support portion BG101b1 is attached to the first vertical support portion BG101a by passing the first vertical support portion BG101a through the vertical support portion through hole BG101b1a.

[0035] The engaging recess BG101b1b is formed in a direction perpendicular to the vertical support through hole BG101b1a and communicates with the vertical support through hole BG101b1a. The engaging recess BG101b1b is formed as an opening that engages with the engaging projection 101 of the fixing device 100.

[0036] Figure 6 shows an exploded perspective view of the upper end of the first vertical support portion BG101a. The first vertical support portion BG101a includes a cylindrical support portion BG101a1, an end cap BG101a3, and a fixing device 100. The cylindrical support portion BG101a1 has a cylindrical shape with a predetermined length. The cylindrical support portion BG101a1 has an engagement opening BG101a1a at a predetermined position that connects the outside and the inside. The engagement opening BG101a1a receives the engagement projection 101 when the upper first horizontal support portion 101b1 is fixed to the first vertical support portion 101a1. The end cap BG101a3 is positioned at the end of the cylindrical support portion BG101a1. The end cap BG101a3 closes the cylindrical shape of the cylindrical support portion BG101a1 at its end.

[0037] The fixing device 100 is positioned inside the cylindrical support portion BG101a1. A portion of the fixing device 100 is integrally formed with the end cap BG101a3. The end cap BG101a3 and the portion of the fixing device 100 integrally formed with the end cap BG101a3 are made of resin.

[0038] Figure 7 shows an exploded cross-sectional view of the fixing device 100. The fixing device 100 has an engaging projection 101, a movable space forming part 103, an elastic part 105, and a cushioning part 107. The engaging projection 101 has an engaging part 101a and a restricting part 101b. The engaging part 101a has a cylindrical shape with a predetermined outer diameter. The restricting part 101b has a cylindrical shape with a larger outer diameter than the engaging part 101a. The restricting part 101b is positioned at one end of the engaging part 101a. The engaging part 101a and the restricting part 101b are formed as a single unit. In other words, the engaging projection 101 has a so-called stepped cylindrical shape. The engaging projection 101 is made of metal.

[0039] The movable space forming section 103 has a movable space 103a that allows the engaging projection 101 to move linearly. The movable space 103a is formed as a cylindrical space that follows the outer shape of the restricting portion 101b of the engaging projection 101. The movable space forming section 103 is integrally formed with the end cap BG101a3 and resin.

[0040] The elastic portion 105 presses the engaging projection 101 in the direction from the inside to the outside of the cylindrical support portion BG101a1 (direction of arrow a3). The elastic portion 105 is formed by a coil spring. The elastic portion 105 is positioned inside the movable space 103a of the movable space forming portion 103.

[0041] The buffer portion 107 is positioned at one end of the movable space 103a of the movable space forming portion 103. The buffer portion 107 has a cylindrical shape. The inner diameter of the buffer portion 107 is such that the engaging portion 101a of the engaging projection 101 can pass through, but the restricting portion 101b of the engaging projection 101 cannot pass through. The outer diameter of the buffer portion 107 is the same size as the movable space 103a of the movable space forming portion 103. The buffer portion 107 is formed integrally with the movable space forming portion 103 from resin.

[0042] In this way, in the fixing device 100, the engaging projection 101 is pressed inward toward the cylindrical support portion BG101a1, compressing the elastic portion 105. After the pressure on the engaging projection 101 is removed, the compressed elastic portion 105 presses the engaging projection 101 outward toward the cylindrical support portion BG101a1, causing it to move until the restricting portion 101b of the engaging projection 101 contacts the buffer portion 107. Even when the restricting portion 101b of the engaging projection 101 contacts the buffer portion 107, the metal engaging projection 101 and the resin buffer portion 107 come into contact, and the metal engaging projection 101, the elastic portion 105, and the cylindrical support portion BG101a1 do not come into contact with each other, thus suppressing the generation of unpleasant, loud noises.

[0043] Operation of the 100 fixed device (part 3) The operation of the fixing device 100 will be explained using Figures 8 to 11. As shown in Figure 8, when the fixing device 100 is attached to the first vertical support portion BG101a, one end of the engaging projection 101 of the fixing device 100, opposite to the restricting portion 103 side of the engaging portion 101a, protrudes from the outer surface of the cylindrical support portion BG101a1 through the engaging opening BG101a1a (see Figure 6) of the cylindrical support portion BG101a1 of the first vertical support portion BG101a.

[0044] With the first vertical support portion BG101a passing through the vertical support portion through hole BG101b1a (see Figure 4) of the upper first horizontal support portion BG101b, the upper first horizontal support portion BG101b1 is moved along the first vertical support portion BG101a in the direction of arrow a8, which points vertically from bottom to top, so that the upper end of the upper first horizontal support portion BG101b1 is fixed to the fixing device 100. When it reaches the position of the engaging projection 101, as shown in Figure 9, the upper first horizontal support portion BG101b1 presses the engaging projection 101 protruding from the outer surface of the cylindrical support portion BG101a1 of the first vertical support portion BG101a through the engaging opening BG101a1a of the cylindrical support portion BG101a, and pushes it into the interior of the cylindrical support portion BG101a1. As a result, the engaging projection 101 moves along the movement space 103a of the movement space forming portion 103. The movement of the engaging projection 101 compresses the elastic portion 105.

[0045] As shown in Figure 10, when the engagement recess BG101b1b of the upper first horizontal support portion BG101b1 reaches the position of the engagement opening BG101a1a of the cylindrical support portion BG101a1 of the first vertical support portion BG101a, that is, the position of the engagement projection 101 of the fixing device 100, the pressure on the engagement projection 101 by the upper first horizontal support portion BG101b1 is eliminated, and the engagement projection 101 is pressed by the compressed elastic portion 105 in the direction from the inside to the outside of the cylindrical support portion BG101a1.

[0046] As shown in Figure 11, the engaging projection 101 of the fixing device 100 engages with the engaging recess BG101b1b of the upper first horizontal support part BG101b1 by passing through the engaging opening BG101a1a of the cylindrical support part BG101a1 of the first vertical support part BG101a. At this time, the engaging projection 101 moves until the restricting part 101b contacts the buffer part 107. Since the buffer part 107 is made of resin, even if it comes into contact with the engaging projection 101 which is made of metal, it will not produce the unpleasant, loud noise that occurs when metal comes into contact with metal. In other words, by using the fixing device 100, the upper first horizontal support part BG101b1 can be fixed to a predetermined position on the first vertical support part BG101a without producing an unpleasant, loud noise.

[0047] [Other embodiments] (1) Formation of the fixing device 100: In the above-described embodiment 1, the end cap BG101a3 and the movable space forming part 103 were formed as a single unit, but they may be formed as separate parts.

[0048] (2) Formation of the buffer portion 107: In the above-described embodiment 1, the buffer portion 107 was formed integrally with the movable space forming portion 103, but it is not limited to the example provided as long as it can form a buffer portion. For example, the buffer portion may be formed as an annular member and placed inside the movable space 103a of the movable space forming portion 103.

[0049] (3) Elastic portion 105: In the above-described embodiment 1, the elastic portion 105 was formed by a coil spring, but it is not limited to the example provided, as long as it can press against the engaging projection 101. For example, a leaf spring or the like may be used. [Industrial applicability]

[0050] The fixing device according to the present invention can be used, for example, in a device for forming a protective fence for a bed that is installed on a bed. [Explanation of symbols]
