Description

  The present invention relates to a shock absorber, and more particularly to a shock absorber capable of uniformly and firmly attaching an elastic material to a side surface of a wooden panel.

  Special attention must be paid to the safety of users in educational facilities and welfare facilities. For this reason, it is said that it is desirable that the protruding portion of the furniture or the wall has a rounded curved line shape or elasticity as much as possible for the purpose of preventing injury at the time of collision.

For the same reason, the door is required to have a curved side surface and to be attached with an elastic material. Especially in kindergartens and preschools, the main subjects are infants and young children, so even if a part of the body such as a finger or hand is caught in the door gap when the door is opened or closed, it will not cause injury. Are required to do so. Therefore, it is necessary to consider attaching a material that has elasticity and a crushable margin to the side surface of the door.
The crush margin is a difference in size between the normal state and the crushed state of the elastic material, and it is necessary to secure about 7 mm or more with reference to the thickness of the infant's finger.

  By the way, to attach elastic material such as elastic rubber to the side surface of the door made of wood material, form a groove on the side surface, fit the elastic material into the groove, and then use an adhesive. It is often practiced to fix an elastic material (for example, Patent Document 1).

JP, 2013-167134, A

  However, after the elastic material is fitted into the groove on the side surface of the door, in order to fix the elastic material with the adhesive, the elastic material is press-fitted into the groove from the side surface direction. Due to its elasticity, it does not transmit well, so it is difficult to fit it evenly without gaps. Therefore, the elastic material needs to have a hardness that can withstand press-fitting, and it is difficult to provide elasticity with a crush margin of about 7 mm or more.

  In addition, it is also possible to fix the elastic material on the side surface of the door without using any grooves or protrusions, but it is easy to bend or make a gap, so it is necessary to spend time carefully. is there. In addition, since it depends only on the adhesive strength of the adhesive, the elastic material easily peels off from the deteriorated parts and gaps of the adhesive. Had to be fixed to.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cushioning tool capable of uniformly and firmly attaching an elastic material to a side surface of a wooden panel.

The wood panel 7 is a wood material made by processing wood, and there are various types. The case where the cushioning tool 3 of the present invention is applied to the sliding door 1 will be described as an example.

FIG. 1 is a front view showing a single sliding door type sliding door 1 including a shock absorber 3 according to the present embodiment.
As shown in FIG. 1, the shock absorber 3 is attached to the entire side surface of the sliding door 1. In this way, the cushioning tool 3 is used, for example, on the side surface of a door such as the sliding door 1 to reduce the impact when the sliding door 1 and the frame member 2 come into contact with each other, and to reduce the gap between the sliding door 1 and the frame member 2. It is designed to be closed.
The cushioning tool 3 is also effective when the frame member 2 is tilted due to a tilt of the building, and can also close the gap between the sliding door 1 and the tilted frame member 2 that occurs in this case.
Further, by using the cushioning tool 3, even when a part of the body such as a finger or a hand is accidentally caught between the sliding door 1 and the frame member 2 during the opening/closing operation of the sliding door 1, it is possible to prevent an injury. ..
As shown in FIG. 1, the cushioning tool 3 may be mounted not only on the entire side surface of the sliding door 1 but also near the center where the handle of the sliding door 1 is located. It can also be attached to only a part of the side surface of the sliding door 1.

FIG. 2 is a cross-sectional view of the cushioning tool 3 of the present invention, and the cushioning tool 3 includes an elastic member 5 and a fixing member 6.
As shown in FIG. 2, the shock absorber 3 is fixed by being fixed in a concave groove 7a formed in a side surface of the wood panel 7 (for example, a side surface of the sliding door 1 made of a wood material). And the elastic member 5 held by being sandwiched between the fixing member 6 and the side surface of the wooden panel 7, and the elastic member 5 reduces the impact.
Since the fixing member 6 has a flat shape along the side surface of the wooden panel 7, the shock absorber 3 is attached to the side surface of the wooden panel 7 while maintaining the cavity inside the elastic member 5.

  Next, with reference to FIG. 3, the elastic member 5 that is a member that specifically constitutes the shock absorber 3 and the fixing member 6 will be described. FIG. 3 shows members constituting the cushioning tool 3 of the present embodiment, and is a sectional view and a sectional perspective view of the elastic member 5, the fixing member 6 and the wood panel 7, respectively.

[Elastic member]
As shown in FIGS. 3(a-1) and 3(a-2), the elastic member 5 is formed in a long tubular shape, and has a surface portion 5a made of a soft material and a bottom portion 5b made of a hard material. Composed of and. Further, the surface portion 5a of the elastic member 5 is formed to have a substantially semicircular cross section, and an opening 5c larger than the bottom surface 60a of the recess 60 of the fixing member 6 described later is formed in a part of the bottom surface portion 5b. Has been formed. That is, the elastic member 5 is composed of a surface portion 5a having a hollow semicircular shape inside, and a bottom surface portion 5b which is partially opened 5c and is held on the side surface of the sliding door 1.
As a material of the elastic member 5, for example, a rubber material such as EPDM rubber excellent in impact resilience, water resistance and weather resistance can be used.
As described above, the impact can be reduced by forming the surface portion 5a of the elastic member 5 in a semi-circular shape and using a rubber material such as EPDM rubber as the material of the elastic member 5.

The cross-sectional shape of the surface portion 5a of the elastic member 5 is not limited to a semicircular shape, and may be, for example, a rectangular shape, a concave shape, a convex shape, or the like. It may have a shape provided with a recess for attaching metal fittings or the like that are more firmly attached.
Next, the surface portion 5a and the bottom surface portion 5b that form the elastic member 5 will be described.

The surface portion 5a is a portion that appears on the front side on the side surface of the wooden panel 7 when the elastic member 5 is attached to the wooden panel 7, and corresponds to a semicircular curved portion.
As the soft material, for example, a sponge material such as EPDM sponge can be used for the surface portion 5a.
As described above, since the surface portion 5a is made of a soft material and formed into a rounded curved shape, a part of the body such as a finger or a hand is caught in the door gap when the door is opened and closed. Even if it does, the elasticity of the surface portion 5a can reduce the impact and prevent the injury.

The bottom surface portion 5b is a portion that comes into contact with the side surface of the wooden panel 7 and is sandwiched by the fixing members 6, and corresponds to straight line portions located on both sides of the lower end of the semicircular curved portion.
Further, the bottom surface portion 5b is formed so as to enter the inner cavity symmetrically about the opening 5c when the elastic member 5 is not attached to the wooden panel 7.
In this way, the bottom portion 5b is inclined so as to enter the cavity inside the elastic member 5, so that when the elastic member 5 is attached to the wood panel 7, the elasticity of the bottom portion 5b to return to the original state. The force can be used to fill the gap between the bottom surface portion 5b of the elastic member 5 and the side surface of the wooden panel 7. Further, since the bottom surface portion 5b of the elastic member 5 and the side surface of the wooden panel 7 are in close contact with each other, the surface portion 5a is projected to the front side by the amount of this inclination, and the collapsing margin can be secured.

Further, the bottom surface portion 5b needs to have a high rigidity so as not to spread outside when being held by the side surface of the wooden panel 7 and the fixing member 6, and therefore, a solid material such as EPDM solid is used, for example.
In this way, by making the side surface of the wooden panel 7 and the portion held by the fixing member 6 the bottom surface portion 5b, the elastic member 5 having softness on the surface portion 5a touched by a finger, a hand, etc. It can be firmly attached to 7.

In addition to the EPDM rubber, the elastic member 5 may be made of other rubber material or resin material such as natural rubber, chloroprene rubber, silicone resin, vinyl chloride resin, ABS resin, polypropylene resin, etc. But it is possible.
Depending on the material selected, the surface portion 5a becomes a sponge material, but in the case of vinyl chloride resin, the surface portion 5a and the bottom surface portion 5b are made of the same material simply by changing the hardness. Can be formed. When materials having the same hardness are used, a thin material is used as the surface portion 5a, and a thick material is used as the bottom surface portion 5b, so that the material having the same hardness is used as the surface portion 5a. Can also be used as the bottom portion 5b.

[Fixing member]
As shown in FIGS. 3(b-1) and 3(b-2), the fixing member 6 is composed of a holding portion 6a and a fixing portion 6b, and the thickness of the member is the impact when fixed to the wood panel 7. It is formed with consideration to withstand. Further, the fixing member 6 is integrally formed into a substantially T-shaped cross section by the holding portion 6a and the fixing portion 6b vertically extending downward from the center of the holding portion 6a.
By thus forming the fixing member 6 in a substantially T-shaped cross-section, the elastic member 5 can be easily inserted between the fixing member 6 and the wood panel 7, and the rigidity of the fixing member 6 can be utilized. Then, the elastic member 5 can be firmly attached.
As a material of the fixing member 6, for example, a synthetic resin such as a hard vinyl chloride resin (PVC) can be used in order to withstand an impact at the time of fixing and improve durability and impact resistance.

The holding portion 6 a includes a concave portion 60 and a curved portion 61, and holds the elastic member 5.
Since the holding portion 6a has a flat shape, it is possible to hold the elastic member 5 on the wooden panel 7 in a state where the elastic member 5 can be collapsed.

The concave portion 60 is formed at a position where the holding portion 6a and the fixing portion 6b intersect with each other, and the bottom surface 60a is wider than the width of the groove 7a of the wood panel 7, and the bottom surface 60a is fixed to the wood panel 7. It is a face.
By providing the concave portion 60 in the fixing member 6, the bottom surface 60a of the concave portion 60 and the side surface of the wooden panel 7 contact in parallel, so that the fixing member 6 can be fixed uniformly to the side surface of the wooden panel 7. As a result, the fixing member 6 can uniformly hold the entire elastic member 5.
Further, since the fixing member 6 is provided with the concave portion 60, the fixing member 6 is evenly brought into contact with the side surface of the wood panel 7, so that when the fixing member 6 is fixed inside the concave portion 60 by using a screw or a tacker, the fixing member 6 is accurately formed. There is an advantage that the fixed position can be grasped and the positioning is easy.

The curved portion 61 is formed on both sides of the concave portion 60 as the center while being curved outward while the center is depressed. This makes it easier to secure a gap between the holding portion 6a of the fixing member 6 and the side surface of the wooden panel 7.
Specifically, in the curved portion 61, when the fixing member 6 is fixed to the wooden panel 7, the gap between the recessed portion of the curved portion 61 and the side surface of the wooden panel 7 has a bottom portion 5 b of the elastic member 5. Is formed to be narrower than the thickness. As a result, the recessed portion of the curved portion 61 serves as a holding surface that holds the bottom surface portion 5b of the elastic member 5 with the side surface of the wooden panel 7.
As shown in FIGS. 3(b-1) and 3(b-2), the holding portion 6a has a shape in which the entire bending portion 61 is gently curved. The shape may be recessed, or a plurality of recesses may be formed.
When forming a plurality of depressions, the bending portion 61 is further extended outward, and the extending bending portion 61 is provided with a plurality of depressions, so that the elastic member 5 matched to the size of the side surface of the wood panel 7 is formed. Can be installed.

The fixing portion 6b is fixed to the wood panel 7 by being fitted into the groove 7a of the wood panel 7.
In the fixing portion 6b, a plurality of sawtooth-shaped projections are formed in the width direction of the groove 7a so as to bite into the wall surface of the groove 7a when the fixing member 6 is fixed to the wooden panel 7.
The sawtooth-shaped projections are arranged at equal intervals, and the slopes of the sawtooth-shaped projections are formed to face the bottom surface of the groove 7a of the wood panel 7.
By providing such a sawtooth-shaped projection on the fixing portion 6b, the fixing portion 6b can be easily fitted into the groove 7a by the elastic force of the projection, and the sawtooth-shaped projection is removed from the groove 7 in the wall surface of the groove 7a. The fixing member 6 becomes difficult to come off from the wooden panel 7 due to being caught by the wooden panel 7. Further, even if there is a slight difference between the width of the fixed portion 6b and the groove width of the wood panel 7, it can be adjusted by forming the saw-toothed protrusions.

  The material of the fixing member 6 may be other resin such as ABS resin, AES resin, PP resin, etc., in addition to vinyl chloride resin, and may be metal such as aluminum. is there.

[Wood panel]
As shown in FIGS. 3C-1 and 3C-2, the wood panel 7 is a wood material obtained by processing wood, and examples thereof include plywood, particle board, fiber board, and laminated wood.
A concave groove 7a is formed on the side surface of the wood panel 7 so as to penetrate in the longitudinal direction, and the width of the groove 7a is formed to be slightly smaller than the width of the fixing portion 6b of the fixing member 6. Further, since the width of the groove 7a is formed to be narrower than the bottom surface 60a of the recess 60 of the fixing member 6, the bottom surface 60a of the recess 60 can be used as a fixing surface to the wood panel 7.

[How to attach shock absorbers]
Hereinafter, a method of attaching the shock absorber 3 composed of such a member to the side surface of the wooden panel 7 will be described.
When attaching the shock absorber 3 of the present embodiment to the side surface of the wooden panel 7, first, as a first procedure, after forming the groove 7a on the side surface of the wooden panel 7, the fixing portion of the fixing member 6 is formed in the groove 7a. Insert and fix 6b.
Specifically, a groove 7a having the same length as the length to which the shock absorber 3 is to be attached is formed on the side surface of the wooden panel 7. Next, the fixing portion 6b of the fixing member 6 is fitted into the groove 7a until the bottom surface 60a of the recess 60 of the fixing member 6 contacts the side surface of the wood panel 7. Here, when firmly fixing the fixing member 6, a screw or a tucker is driven into the recess 60 toward the groove 7a. At this time, the length of the screw or the tacker is fixed using the screw or the tacker longer than the depth of the groove 7a of the wood panel 7.
The fixing member 6 and the side surface of the wood panel 7 may be fixed by pouring an adhesive agent into the groove 7a in advance without using a screw or a tacker.
Further, before using a screw or a tacker, an adhesive is poured into the groove 7a, the fixing portion 6b of the fixing member 6 is fitted into the groove 7a, and after fixing with the adhesive, in order to suppress the fixing member 6 from floating, Alternatively, it may be fixed by using a screw or a tacker.

Next, as a second procedure, the elastic member 5 is clamped between the side surface of the wooden panel 7 and the fixing member 6.
Specifically, the bottom surface portion 5b of the elastic member 5 is inserted between the side surface of the wooden panel 7 and the curved portion 61 of the fixing member 6 from the end portion on the opening 5c side, and is sandwiched. At this time, since the gap between the curved portion 61 of the fixing member 6 and the side surface of the wooden panel 7 is formed to be narrower than the thickness of the bottom surface portion 5b of the elastic member 5, the bottom surface portion 5b of the elastic member 5 is While pushing up the bending portion 61 upward, the bending portion 61 is inserted between the side surface of the wooden panel 7 and the bending portion 61.
Thus, when the bottom surface portion 5b of the elastic member 5 is sandwiched between the side surface of the wooden panel 7 and the curved portion 61 of the fixing member 6, the curved portion 61 that has been pushed up and elastically deformed has its original shape. The bottom surface portion 5b of the elastic member 5 is firmly sandwiched by the elastic force to return to, and is firmly held between the bottom surface portion 5b and the side surface of the wooden panel 7.

Finally, as a third step, if necessary, an adhesive is injected and fixed between the bottom surface portion 5b of the elastic member 5 and the side surface of the wooden panel 7, and the cushioning tool 3 is attached to the wooden panel 7. Finish the installation.
Specifically, an adhesive containing a volatile organic compound is injected and fixed between the bottom surface portion 5b of the elastic member 5 and the side surface of the wooden panel 7. At this time, the adhesive is used partially or supplementarily, not entirely.
This is because the elastic force of the holding portion 6a of the fixing member 6 sandwiches the bottom surface portion 5b of the elastic member 5 between the side surface of the wood panel 7 and holds the elastic member 5 evenly and firmly, so that the entire member is bonded. This is because it is not necessary to use an agent.
As a result, the dissolution of the elastic member 5 due to the volatile substance of the adhesive can be suppressed to the minimum, and the deterioration of the elastic member 5 can be suppressed. Further, when the elastic member 5 is deteriorated, since no adhesive is used on the whole, replacement with a new elastic member 5 becomes easy.

In addition to the above-described method of attaching the shock absorber 3, as shown in FIG. 5, the holding portion 6a of the fixing member 6 is previously inserted into the cavity inside the elastic member 5, and the state is maintained, The fixing portion 6b of the fixing member 6 may be fitted in the groove 7a to be fixed.
That is, after the adhesive is poured into the groove 7a in advance, the fixing portion 6b of the fixing member 6 is provisionally arranged in the groove 7a, and the surface portion 5a of the elastic member 5 is hit by a hammer or the like from the front side and fixed. Become.
At this time, it is preferable to interpose a patch or the like between the elastic member 5 and the hammer so that the elastic member 5 is not damaged.
As a result, the fixing portion 6b of the fixing member 6 goes deep into the groove 7a, and the plurality of sawtooth-shaped projections formed on the fixing portion 6b are also caught on the wall surface of the groove 7a, which contributes to the adhesive force of the adhesive. Thus, the fixing member 6 is firmly fixed to the side surface of the wooden panel 7 while holding the elastic member 5.

  As described above, the cushioning tool 3 can be attached to the side surface of the wooden panel 7 uniformly and firmly with relatively simple attachment, and even when the elastic member 5 is deteriorated, the elastic member 5 can be replaced. Can also be done easily. Furthermore, since the shock absorber 3 of the present invention has a simple structure, it can be easily repaired and can be used regardless of the mounting location.

FIG. 4A is an explanatory diagram showing a state in which a cushioning tool 3 of the present invention is attached to a sliding door 1 of a single sliding door type and a sliding door 1 of a double sliding door type is sandwiched with fingers, respectively.
As described above, the cushioning tool 3 of the present invention can be applied to various sliding doors 1, and further, (a) between the sliding door 1 and the frame member 2, and (b) between the sliding door 1 and the sliding door 1. Even if a finger is caught, the elastic member 5 is crushed, but since the elastic member 5 has a cavity inside and the holding portion 6a of the fixing member 6 is flat along the side surface of the wooden panel 7, The elasticity can prevent the finger from hitting the fixing member 6.
That is, since the elastic member 5 of the cushioning tool 3 has elasticity and a crushable margin that do not lead to injury, the impact can be reduced.
Further, if the cushioning tool 3 is used, even if the finger is caught, the finger can be easily pulled out with a small force, and the elastic member 5 returns to the original shape by the elastic force when the finger is pulled out.

Although the preferred embodiment of the shock absorber 3 of the present invention has been described above, the shock absorber 3 according to the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention.
For example, in the above-described embodiment, the cushioning tool 3 of the present invention is used for the sliding door 1 such as the "single sliding door" or the "double sliding door (sliding door)", but the two sliding doors 1 can be moved left or right. It can be used for various doors such as a sliding door that can be opened and closed, and a hinged door that can be opened and closed.
It can also be used for wood panels 7 other than doors, and as a modified example, for example, a side surface of a screen, a side surface of a counter, a side surface of a frame member 2 as shown in FIG. 6(a), and a side surface of FIG. 6(b). As shown, the cushioning tool 3 of the present invention can be used on the side surface of furniture (table). In the case of the furniture (table) of FIG. 6(b), by using the cushioning tool 3, the protruding portion of the furniture (table) can be formed into a rounded curved shape, so that the Can prevent injuries.
In this way, when opening and closing the door, in addition to reducing the impact when a part of the body such as a finger or hand is caught in the gap between the doors, the cushioning tool 3 is also attached to a protruding portion such as furniture or a wall. It can be used, and in this case, it is possible to reduce the impact when it collides with the protruding portion.
