  A pull handle in the embodiment of the present invention will be described with reference to FIGS. The puller 10 is attached to a fixing part 50 such as a door or a drawer by a screw 40. Examples of the door include a sliding door, a raising door, and a revolving door. Among these, the effect of the present invention is remarkably exhibited by the revolving door. In addition, examples of the drawer include various forms such as a drawer that is pulled forward.

  The puller 10 has a protruding puller body 1 in front. The puller body portion 1 is a handle portion, and has a protruding shape in front, thereby forming a gap 3 between the puller main body portion 1 and the fixed portion 50, and a finger enters the gap 3, and the puller main body portion. 1 can be gripped. In this example, the puller main body 1 has a semicircular arc shape (arch shape) in plan view, an end portion that is an attachment end surface 15, and a substantially rectangular shape in front view. Further, in the plan view of the handle main body 1, the width gradually increases from the center to the end in the lateral direction. Thereby, since the attachment end surface can be widely used, it is possible to form the fixing screw hole 12 and the locking portion 142 of the cover member 2.

  The puller main body 1 is made of a metal and exhibits the effects of the present invention remarkably. It does not restrict | limit especially as a metal, Zinc die-casting, brass, stainless steel, etc. or these surface finishes are mentioned. In addition, the metal includes, for example, a plated chrome plated surface such as plastic. By making the handle main body 1 made of metal, it is easy to use and can be used stably for a long time.

A cutout groove 14 is formed on the front surface of the puller body 1. In other words, the hollow groove 14 is a groove having a predetermined width w ₂ and a predetermined depth h in a plan view from one end to the other end. Therefore, the upper and lower sides of the hollow groove 14 are an upper wall portion 11 a and a lower wall portion 11 b that form the upper and lower surfaces of the pull handle main body 1. Further, both end portions of the hollow groove 14 are further provided with a locking portion 142 extending inward to form a step and continue to the attachment end surface 15. That is, the claw 221 of the cover member 2 is locked to the locking portions 142 at both ends. As a result, when the cover member 2 is fitted, the end surface of the cover member 2 is locked to the locking portion 142 and is flush with the mounting end surface 15 of the puller main body portion 1, which obstructs the mounting. There is nothing. On the other hand, since the front surface of the puller main body 1 is partly protruded from the cover member 2 (front side), it does not hurt even if it collides with other fittings and is safe even if it comes in contact with people. is there. In addition, as shown in FIG. 4, although the protrusion of a part of the cover member 2 is gradually reduced from the center to the end, it is not limited to this, and even if it has a uniform length from the center to the end. Good. The ratio of the hollow groove width w ₂ to the thickness w ₁ of the puller body portion 1, w ₂ / w ₁ , is generally 0.5 to 0.7, preferably 0.6.

  Further, a screw hole 12 is formed inside the locking portion 142 where the cover member 2 is locked at the attachment end 15 of the puller main body 1. The screw hole 12 is formed so as to penetrate the handle main body 1 forward from the attachment end 15. Thereby, the screw hole 12 is screwed forward with the screw hole 12 by advancing the screw forward from the back side of the fixing portion 50, and the fixing portion 50 and the handle main body portion 1 are fixed. Note that the screw length may be a length that allows the screw tip to contact the cover member 2 or not.

  The puller 10 includes a resin cover member 2 that is fixed to the front surface of the puller main body 1, preferably the entire front surface by fitting. That is, the front surface of the puller main body portion 1 refers to a portion where a semicircular arc shape (arch shape) appears, excluding the end portion. That is, the cover member 2 is fitted into the hollow groove 14, and a part of the cover member 2 protrudes as a protruding tooth from the front surface of the pull handle main body 1. That is, the cover member 2 appears at all front ends of the portion protruding from the fixed portion 50. This prevents people from being injured by contact. In addition, about 2 mm is sufficient for the length of the protruding teeth of the cover member 2 protruding from the front surface of the puller main body 1.

  The cover member 2 has a notch or a cavity that provides cushioning properties at the center in the longitudinal direction of the cover member 2. The shape or the like of the cutout portion or the hollow portion is not particularly limited as long as it gives cushioning properties to the external force P as shown in FIG. As shown in FIGS. 11 to 13, the notch has a shape such that a gap s is formed on the contact surface with the puller main body 1 when fitted into the puller main body 1. That is, the notch is notched so that the thickness is smaller than the smooth arc-shaped surface of the back surface 231 of the cover member 2. By forming the notch portion 23, the cover member 2 of the portion becomes thin, the spring action is increased, and cushioning properties are obtained. The length and thickness of the notch 23 are appropriately determined, but the length of the notch 23 is preferably about 1/4 to 1/2 of the arc length of the cover member 2, particularly preferably 1/3. Yes, the thickness of the notch 23 may be about 1 mm to 3 mm. Moreover, the hollow part is a hole penetrating in the width direction of the cover member 2. The cavity 23a in FIG. 14 is a through hole having an elliptical shape and an arc shape in plan view, and the cavity 23b in FIG. It is formed continuously in the longitudinal direction. The hole penetrating in the width direction of the cover member 2 is preferably one that is hidden by the puller body 1 and cannot be seen from the outside when fitted into the puller body 1. The cavity may be a confined cavity that does not penetrate in the width direction of the cover member 2. These hollow portions are cushioned against the external force P. Further, both the notch and the cavity may be formed.

  The resin of the cover member 2 preferably has a flexural modulus of 1.8 GPa or more, preferably 2.0 GPa or more in terms of strong spring force and sufficient fitting strength. Examples of the resin include acrylonitrile / butadiene / styrene (ABS) resin, polyacetal, and nylon. Specific examples include Duracon “M90-44”; flexural modulus 2.6 GPa (manufactured by Polyplastics), Iupital “ F20 "; flexural modulus 2.6 GPa (manufactured by Mitsubishi Engineering Plastics), Tanazine" TN500 "; flexural modulus 2.5 GPa (manufactured by Takayasu), Tanadine" TN710 "; flexural modulus 2.9 GPa (manufactured by Takayasu) ).

As shown in FIGS. 11 and 12, the cover member 2 has a shape similar to the arch shape of the puller main body 1 as a whole, and both ends are claws 221 extending inward. As a result, it is possible to strongly engage with the engaging portion 142 of the puller main body 1. The cover member 2 is an elastic body, and the gap between the claws 221 at both ends is widened by spreading both sides against the spring force. That is, by pushing the cover member 2 strongly into the hollow groove 14 of the puller main body 1 by hand, the initial distance L ₀ between the claws 221 expands to L ₁ , and after fitting, it is restored to restore both Will be integrated. That is, the elasticity of the cover member 2 is such that it is finally deformed by a strong hand force. Thereby, after fitting, it does not come off easily.

  A double-sided tape (not shown) may be attached to the inside of the cover member 2, that is, the inner surface of the arch-shaped inner layer 22. By forming the double-sided tape on the inner surface of the inner layer 22, the attachment strength of the cover member 2 to the puller main body 1 is improved. In addition, a slight recess may be formed at the location in the direction in which the mounting screw of the cover member 2 advances. Thereby, the tip of the mounting screw does not enter the cover member 2.

Next, a method for assembling the puller 10 will be described with reference to FIGS. In FIG. 12 and FIG. 13, in order to make the engagement state of the puller main body 1 and the cover member 2 easy to understand, the puller main body 1 is shown in a cross section as shown in FIG. 10. First, the cover member 2 with the pair of claws 221 facing the pulling body portion 1 side from the front side of the pulling body portion 1 is fitted into the hollow groove 14. At this time, since the distance L ₀ between the pair of claws 221 is smaller than the maximum length L ₁ of the hollow groove 14, the cover member 2 is inserted into the hollow groove 14 as shown in FIG. In addition, the tips of the pair of claws 221 come into contact with the groove bottom surfaces 141 near both ends of the hollow groove 14. From this state, the cover member 2 is strongly pressed against the puller main body 1 side against the spring force and is fitted. As a result, after the initial distance L ₀ between the claws 221 extends to L ₁ and the cover member 2 is fitted in the hollow groove 14, both are strongly fitted and integrated by restoration ( FIG. 13).

  The cover member may have a two-layer structure of an inner layer 22 and an outer layer 21 made of resin that are fixed by fitting into the front surface of the puller main body 1, preferably the entire front surface. As a fitting form of the inner layer 22 and the outer layer 21 excluding the notch 23 in the two-layer structure, for example, a form as shown in FIG. That is, the inner layer 22 includes a base 223 and a protrusion 224 that protrudes upward from the center of the base 223, and the outer layer 21 has a concave shape in which the shape of the protrusion 224 of the inner layer 22 is hollowed out. Thereby, the fitting strength between the inner layer 22 and the outer layer 21 is improved.

  In the cover member 2c, the inner layer 22 is preferably a hard resin or metal, and the outer layer 21 is preferably a softer resin (hereinafter also referred to as “soft resin”). Particularly preferably, the inner layer 22 is a hard resin and the outer layer 21 is a soft resin. It is. Thereby, it can fit firmly on the fixed side, and cushioning properties will increase on the protruding side. In addition, it is preferable to form the cutout portion or the hollow portion in the outer layer 21 in terms of further improving cushioning properties. As in the case of the cover member 2, the formation position of the cutout portion or the hollow portion in the outer layer 21 is the central portion in the longitudinal direction of the cover member 2 c. As a specific form of the notch or the cavity in the outer layer 21, the same as that of the cover member 2 is exemplified. As the hard resin, the same resin as the resin of the cover member 2 can be used. As the soft resin, silicone resin (SI), polyurethane resin (PUR), vinyl chloride resin (PVC), ethylene vinyl acetate copolymer resin (EVA), EEA resin (EEA), thermoplastic polyurethane elastomer (TPU), A thermoplastic elastomer (TPE) is mentioned. The soft resin has a Shore hardness of 40 to 90, preferably 50 to 80. The adhesion between the hard resin 22 and the soft resin 21 can be integrated by molding the resins. If an ABS resin is used as the hard resin and a soft elastomer is used as the soft resin, it is preferable in terms of improving adhesiveness between the resins. The inner layer 22 can be made thinner than the outer layer 21 because a hard resin is used. That is, the thickness of the inner layer 22 may be 1/6 to 1/2 of the outer layer 21.

  Similar to the cover member 2, the cover member 2c has a shape similar to the arch shape of the puller main body 1 as a whole, and both end portions are claws 221 extending inward (FIGS. 16 and 18). ). In other words, the claw 221 extending inward is formed by bending both ends of the hard resin inward so that the inner angle becomes an acute angle. As a result, it is possible to strongly engage with the engaging portion 142 of the puller main body 1. On the other hand, the soft resin 21 is laminated on the outer periphery of the hard resin 22. Thereby, the end surfaces of the hard resin 22 and the soft resin 21 are flush with each other, the outer side is a soft resin, and the inner side is a hard resin including the locking claws 221. In addition, the cover member 2c has the effect of attachment similar to the cover member 2 (FIGS. 18, 19, and 20).

  In the present invention, the puller main body 1 is not limited to the arch shape of the above embodiment, and for example, a substantially square shape, an indefinite shape, or the like can be used. In this case, the cover members 2, 2 a to 2 c also correspond to the shape of the pull handle main body 1. Further, in the present invention, what protrudes from the front surface of the pull main body 1 is not limited to a part of the outer layer, and the entire outer layer may protrude.

  According to the puller 10 of the present invention, for example, when the puller of the revolving door is pulled forward, the cover members 2, 2 a to 2 c of the puller 10 may be used even if they collide with other adjacent building tools. Therefore, other construction tools will not be damaged by the action of mitigating the collision. Further, even if the puller 10 touches the elderly hand or foot, the cover member hits the elderly person so that the elderly person is not damaged.
