Description

拉出構造 Pull out structure

本發明係關於一種拉出構造。 The present invention relates to a pull-out structure.

習知，於在廚房之水槽下等拉出構造，機櫃(cabinet)內滑動之拉出本體之內部收納有較重之物品，或者拉出本體之深度尺寸較大之情形時，為了將拉出本體拉出需要較大之力。因此，已知有一種技術：將拉出本體之前板利用拉出本體之下端部可旋動地軸支，利用該原理以一面使之向前方傾斜一面打開之方式構成(例如，參照專利文獻1)。 Conventionally, in the case of a pull-out structure under the sink of the kitchen, the pull-out body that slides in the cabinet contains heavier items, or the depth of the pull-out body is large, in order to pull out It takes a lot of force to pull out the main body. Therefore, there is known a technique in which a plate is rotatably supported by the lower end of the pull-out body before the body is pulled out, and the principle is used to construct it so that it is tilted forward and opened (for example, refer to Patent Document 1) .

於該技術中，於機櫃之側板之內面，設置向內側突出之突起部，另一方面，於拉出本體側之側板部，設置能夠抵接於突起部之抵接部及控制拉出本體之前後之移動之齒輪部。而且，提出有藉由於利用齒輪部之活動使拉出本體向前方移動之後，使拉出本體之抵接部抵接於突起部之狀態下，以使拉出本體之前板部向近前側旋轉之方式打開，藉此減小將拉出本體拉出之最初之力。 In this technique, a protrusion that protrudes inward is provided on the inner surface of the side plate of the cabinet. On the other hand, a side plate portion on the side of the pull-out body is provided with an abutment portion capable of contacting the protrusion and controls the pull-out of the body The gear part that moves before and after. Furthermore, it has been proposed that after the pull-out body is moved forward due to the movement of the gear portion, the abutment portion of the pull-out body is brought into contact with the protruding portion, so that the plate portion is rotated to the near side before the body is pulled out. The way is opened, thereby reducing the initial force of pulling out the main body.

於以使打開拉出本體之最初之力減小之方式構成之情形時，伴隨其，以拉出本體自關閉之狀態不打開之方式保持之力減小。因此，為了使關閉之狀態之拉出本體之前板自然地打開且拉出本體不向前方移動，而必須將控制拉出本體之前後之移動之齒輪部之嚙合調節為既定之齒輪比。 When it is constructed in such a way that the initial force to open and pull out the main body is reduced, accompanying it, the holding force is reduced in such a way that the pull out main body does not open from the closed state. Therefore, in order to allow the plate before the body to be pulled out in the closed state to naturally open and the body to be pulled out does not move forward, it is necessary to adjust the meshing of the gear part that controls the movement before and after the body is pulled out to a predetermined gear ratio.

若將齒輪部之齒輪比調節為如於關閉時拉出本體不向前方移動之程度，則於使拉出本體滑動之期間，施加較為了打開拉出本體而實際施加之力大之力。因此，存在正當將拉出本體拉出之動作時，無法使打開之力最小化之問題。 If the gear ratio of the gear portion is adjusted to the extent that the pull-out body does not move forward when the pull-out body is closed, a force greater than the force actually applied when the pull-out body is opened is applied during the sliding of the pull-out body. Therefore, there is a problem that the opening force cannot be minimized when the pull-out body is pulled out.

The rack member 44 is a substantially cubic member arranged to extend in the front-rear direction along the lower edge of the housing portion 40. The rack member 44 is flat, and the area of the upper surface and the lower surface is larger than that of the side surface. The rack member 44 is formed in two rows of thin rack grooves along the width direction on the upper surface. The rack member 44 has a flat portion 440, a second rack gear 442, and a third rack gear 443. As described below, the flat portions 440, the second rack gear 442, and the third rack gear 443 are arranged on the rack member 44, thereby constituting a gear ratio variable mechanism.

第2齒條齒輪442係形成於齒條構件44上表面之寬度方向之一側。第2齒條齒輪442係位於齒條構件44中拉出側板部33之外側(即，機櫃2之側板25側)之行。第2齒條齒輪442配置於齒條構件44中後方之端部側。 The second rack gear 442 is formed on one side in the width direction of the upper surface of the rack member 44. The second rack gear 442 is located in the row of the rack member 44 on the outer side of the side plate 33 (that is, the side plate 25 side of the cabinet 2). The second rack gear 442 is arranged on the rear end side of the rack member 44.

第3齒條齒輪443係形成於齒條構件44上表面之寬度方向之另一側。第3齒條齒輪443係位於齒條構件44中拉出側板部33之內側之行。第3齒條齒輪443係於將齒條構件44之長邊方向之一側及另一側之除端部外之大致中央部之靠後沿著長邊方向而形成。第3齒條齒輪443係自齒條構件44上表面向上方***既定高度，於經***之部分之上表面形成有齒條槽(參照圖5及6)。第3齒條齒輪443係較第2齒條齒輪442更高地***，並且較第2齒條齒輪442更長。例如，第3齒條齒輪443具有第2齒條齒輪442之5~7倍之長度。 The third rack gear 443 is formed on the other side of the upper surface of the rack member 44 in the width direction. The third rack gear 443 is located on the inner side of the side plate portion 33 drawn out of the rack member 44. The third rack gear 443 is formed along the longitudinal direction from one side of the rack member 44 in the longitudinal direction and at the rear of the substantially central portion of the other side except for the ends. The third rack gear 443 is raised from the upper surface of the rack member 44 to a predetermined height upward, and a rack groove is formed on the upper surface of the raised portion (refer to FIGS. 5 and 6). The third rack gear 443 swells higher than the second rack gear 442 and is longer than the second rack gear 442. For example, the third rack gear 443 has 5-7 times the length of the second rack gear 442.

平坦部440係齒條構件44上表面中未形成齒條槽之部分。如圖3所示，於第3齒條齒輪443之後端部與第2齒條齒輪442之前端部之間，形成有間隙，平坦部440亦於該間隙延伸。 The flat portion 440 is a portion of the upper surface of the rack member 44 where no rack groove is formed. As shown in FIG. 3, a gap is formed between the rear end of the third rack gear 443 and the front end of the second rack gear 442, and the flat portion 440 also extends in the gap.

如圖3及圖4所示，小齒輪部45係於齒條構件44之上於前後移動之齒輪。小齒輪部45係作為第1小齒輪之大齒輪451及作為第2小齒輪之小齒輪452同軸且可一體旋轉地設置之雙重之齒輪。 As shown in FIGS. 3 and 4, the pinion portion 45 is a gear that moves forward and backward on the rack member 44. The pinion portion 45 is a double gear in which the large gear 451 as the first pinion gear and the pinion gear 452 as the second pinion gear are coaxially and integrally rotatably provided.

大齒輪451能夠與齒條構件44之第2齒條齒輪442嚙合並旋轉。大齒輪451係於齒條構件44之拉出側板部33側旋轉。 The large gear 451 can mesh with the second rack gear 442 of the rack member 44 and rotate. The large gear 451 is rotated on the side of the pull-out side plate portion 33 of the rack member 44.

小齒輪452係較大齒輪451齒數少且直徑小之齒輪。小齒輪452能夠與設置於滑動板42下緣之第1齒條齒輪421嚙合並旋轉。又，小齒輪452與第3齒條齒輪443嚙合。 The pinion gear 452 is a larger gear 451 with a small number of teeth and a small diameter. The pinion 452 can mesh with and rotate with the first rack gear 421 provided on the lower edge of the sliding plate 42. In addition, the pinion gear 452 meshes with the third rack gear 443.

抵接部46係自齒條構件44向寬度方向之外側突出之突起。抵接部46係於收容於收容部4之狀態下，自收容部4之抵接部插通槽401向拉出側板部33之側突出。抵接部46伴隨齒條構件44之移動而於拉出本體3內於前後移動。抵接部46係於機櫃2之側板25之內側，抵接於朝向拉出本體3突出之突起部26。 The contact portion 46 is a protrusion protruding from the rack member 44 to the outside in the width direction. The abutting portion 46 protrudes from the abutting portion insertion groove 401 of the receiving portion 4 to the side where the side plate portion 33 is drawn out in a state of being accommodated in the receiving portion 4. The abutting portion 46 moves back and forth in the pull-out body 3 in accordance with the movement of the rack member 44. The abutting portion 46 is located on the inner side of the side plate 25 of the cabinet 2 and abuts against the protrusion 26 protruding toward the pull-out body 3.

圖5及圖6係表示小齒輪部45與齒條構件44嚙合狀態之立體圖。圖5係表示拉出本體3處於收納位置時之小齒輪部45與齒條構件44。於收納位置中，大齒輪451與第2齒條齒輪442嚙合。 5 and 6 are perspective views showing a state in which the pinion gear portion 45 and the rack member 44 are meshed with each other. FIG. 5 shows the pinion portion 45 and the rack member 44 when the pull-out body 3 is in the storage position. In the storage position, the large gear 451 meshes with the second rack gear 442.

圖6係表示拉出本體3自機櫃2內拉出之中途之狀態。於將拉出本體3自機櫃2內拉出之期間，小齒輪452與第3齒條齒輪443嚙合。 FIG. 6 shows a state in which the main body 3 is pulled out from the cabinet 2 in the middle. During the period when the pull-out body 3 is pulled out from the cabinet 2, the pinion gear 452 meshes with the third rack gear 443.

參照圖7~9，對拉出本體3之自收納位置至拉出位置為止之活動進行說明。 With reference to Figs. 7-9, the movement of the main body 3 from the storage position to the pull-out position will be described.

拉出本體3係自機櫃2之開口部21***，由軌道5引導而於機櫃2內於前後方向滑動。 The pull-out body 3 is inserted from the opening 21 of the cabinet 2 and is guided by the rail 5 to slide in the cabinet 2 in the front-rear direction.

圖7係收納位置中拉出構造1之縱剖面圖。如圖5及圖7所示，在處於收納位置時，齒條構件44位於拉出側板部33之近前側。又，為抵接部46亦位於拉出側板部33之近前側，且與機櫃2之側板25之突起部26離開之狀態。進而，滑動板42及撐條43亦又位於裡側，故而連接於撐條43之拉出前板部34關閉。 Fig. 7 is a longitudinal sectional view of the drawing structure 1 in the storage position. As shown in FIGS. 5 and 7, when in the storage position, the rack member 44 is located on the near front side of the pull-out side plate portion 33. In addition, it is a state where the abutting portion 46 is also located on the near front side of the pulled-out side plate portion 33 and is separated from the protruding portion 26 of the side plate 25 of the cabinet 2. Furthermore, the sliding plate 42 and the stay 43 are also located on the inner side, so the front pull-out part 34 connected to the stay 43 is closed.

於收納位置中，大齒輪451與第2齒條齒輪442嚙合，小齒輪452與構成第1連桿構件之第1齒條齒輪421嚙合，齒輪比為1：1.4。於該狀態下，即 使在如於拉出前板部34之前收納箱34b收納有廚房用品而施加有荷重之情形時，第2齒條齒輪442與大齒輪451之嚙合之阻力亦較大，拉出本體3不會於近前打開。 In the storage position, the large gear 451 meshes with the second rack gear 442, and the small gear 452 meshes with the first rack gear 421 constituting the first link member, and the gear ratio is 1:1.4. In this state, that is When the storage box 34b contains kitchen utensils before pulling out the front plate portion 34 and a load is applied, the resistance of the meshing between the second rack gear 442 and the large gear 451 is also greater, and the body 3 will not be pulled out. Open near.

此外，於收納位置中，撐條43及滑動板42係以於前後方向延伸且上下之位置大致相同之方式配置。 In addition, in the storage position, the stay 43 and the sliding plate 42 are arranged in such a manner that they extend in the front-rear direction and have substantially the same upper and lower positions.

圖8係拉出本體3自收納位置向拉出位置移動中途之拉出構造1之縱剖面圖。 FIG. 8 is a longitudinal sectional view of the pull-out structure 1 during the movement of the pull-out body 3 from the storage position to the pull-out position.

拉出本體3亦藉由配設於機櫃2內之軌道5內之拉伸彈簧52而向裡側施力。因此，為了將拉出本體3拉出，而用手把持拉出前板部34之把持部34a，與拉伸彈簧52之力對抗，以較大之力使拉出構造1向近前側拉伸。此時，將拉出本體3向近前側拉之力施加至與第2齒條齒輪442嚙合之大齒輪451，與拉伸彈簧52之力對抗而打開拉出構造1。例如，於大齒輪451與第2齒條齒輪442嚙合並移動之期間，為將拉伸彈簧52拉伸之區間中最初之10mm~15mm左右。 The pull-out body 3 is also forced to the inner side by the tension spring 52 arranged in the rail 5 in the cabinet 2. Therefore, in order to pull out the pull-out body 3, the grip portion 34a of the pull-out front plate portion 34 is gripped by hand to oppose the force of the tension spring 52, and the pull-out structure 1 is stretched to the near side with a relatively large force. At this time, the force of pulling the pull-out body 3 to the near side is applied to the large gear 451 meshed with the second rack gear 442, and the pull-out structure 1 is opened by opposing the force of the tension spring 52. For example, during the period during which the large gear 451 and the second rack gear 442 are meshed and moved, the first 10 mm to 15 mm in the section in which the tension spring 52 is stretched is stretched.

藉由將拉出前板部34拉出，連結於拉出前板部34之撐條43及滑動板42向近前移動。伴隨撐條43及滑動板42之移動，齒輪機構藉由大齒輪451及小齒輪452而變更齒輪比，經由與滑動板42嚙合之第1齒條齒輪421而將撐條43及滑動板42之動力傳遞至齒條構件44。 By pulling out the front pull-out portion 34, the stay 43 and the sliding plate 42 connected to the front pull-out portion 34 move forward. Along with the movement of the stay 43 and the sliding plate 42, the gear mechanism uses the large gear 451 and the small gear 452 to change the gear ratio. The first rack gear 421 meshed with the sliding plate 42 changes the distance between the stay 43 and the sliding plate 42. The power is transmitted to the rack member 44.

如圖6等所示，第2齒條齒輪442較短。又，第3齒條齒輪443係與第2齒條齒輪442於前後方向錯開配置。因此，若第2齒條齒輪442與大齒輪451嚙合，並向裡側移動，則其後第3齒條齒輪443立即與小齒輪452嚙合，齒條構件44進而向裡側前進。 As shown in FIG. 6 etc., the second rack gear 442 is relatively short. In addition, the third rack and pinion 443 series and the second rack and pinion 442 are arranged shifted in the front-rear direction. Therefore, when the second rack gear 442 meshes with the large gear 451 and moves to the inner side, the third rack gear 443 immediately meshes with the pinion 452 thereafter, and the rack member 44 further advances to the inner side.

此外，於小齒輪452與第3齒條齒輪443嚙合之期間，於設置有第2齒條齒輪442之側之行，由於平坦部440延伸，故於第2齒條齒輪442上通過之後，大齒輪451不與齒條構件44卡合。 In addition, during the meshing period of the pinion 452 and the third rack gear 443, on the side where the second rack gear 442 is provided, the flat portion 440 extends, so after passing on the second rack gear 442, the large The gear 451 is not engaged with the rack member 44.

第3齒條齒輪443係相對第2齒條齒輪442朝向大齒輪451及小齒輪452之軸向錯開配置，第3齒條齒輪443係配置於齒條構件44之拉出本體3側。即，小齒輪452與第1齒條齒輪421及第3齒條齒輪443嚙合，且第1齒條齒輪421與第3齒條齒輪443之齒輪比為1：1。因此，將拉出本體3拉出之力係於最初拉出之動作之後立即變輕、變小。例如，於小齒輪452與第3齒條齒輪443嚙合並移動之期間，為將拉伸彈簧52拉伸之區間中剩餘之最初之45mm~50mm左右。 The third rack and pinion 443 is arranged offset from the second rack gear 442 toward the axial direction of the large gear 451 and the pinion 452, and the third rack and pinion 443 is arranged on the side of the pull-out body 3 of the rack member 44. That is, the pinion gear 452 meshes with the first rack gear 421 and the third rack gear 443, and the gear ratio of the first rack gear 421 and the third rack gear 443 is 1:1. Therefore, the force of pulling out the main body 3 is lightened and reduced immediately after the initial pulling out action. For example, during the period during which the pinion gear 452 meshes with the third rack gear 443 and moves, it is about the first 45 mm-50 mm remaining in the section in which the tension spring 52 is stretched.

如此，伴隨將拉出本體3拉出之動作，進行第2齒條齒輪442及大齒輪451之嚙合與第3齒條齒輪443及小齒輪452之嚙合之切換。因此，藉由利用齒輪比可變機構，具備齒數相互不同之大齒輪451及小齒輪452，可與構成第1連桿構件之滑動板42及撐條43一起，於拉出本體3向近前側前進時變更齒輪比。 In this way, in accordance with the action of pulling out the pull-out body 3, the meshing of the second rack gear 442 and the large gear 451 and the meshing of the third rack gear 443 and the pinion 452 are switched. Therefore, by using the gear ratio variable mechanism, the large gear 451 and the small gear 452 with different numbers of teeth can be used together with the sliding plate 42 and the stay 43 constituting the first link member to pull out the main body 3 to the near side. Change the gear ratio when moving forward.

於齒條構件44一面與小齒輪部45嚙合，一面自近前向裡側前進之期間，與小齒輪452經由第1齒條齒輪421而嚙合之滑動板42向近前側前進。若滑動板42向近前側前進，則安裝於滑動板42之撐條43自收容部4之撐條孔402出來並向近前移動。此外，因於滑動板42設置有臂部422，且於臂部422利用磁體吸附支持內拉出件35，故伴隨滑動板42之移動，內拉出件35亦向前方移動。 While the rack member 44 is meshed with the pinion portion 45 while advancing from the front to the back, the sliding plate 42 meshed with the pinion 452 via the first rack gear 421 advances to the near side. When the sliding plate 42 advances toward the front side, the stay 43 attached to the sliding plate 42 comes out of the stay hole 402 of the receiving portion 4 and moves forward. In addition, since the sliding plate 42 is provided with an arm portion 422, and the arm portion 422 is attracted and supported by the inner pullout member 35 by a magnet, the inner pullout member 35 also moves forward as the sliding plate 42 moves.

圖9係拉出位置中拉出構造1之縱剖面圖。 Fig. 9 is a longitudinal sectional view of the drawing structure 1 in the drawing position.

如圖9所示，作為第2連桿構件之齒條構件44之抵接部46抵接於設置於機櫃2之側板25之突起部26。於抵接部46抵接於突起部26之狀態下，若將拉出本體3繼續拉出，則抵接部46以突起部26為支點，以將拉出本體3壓出之方式，產生朝向近前側之反作用力。藉由該反作用力，而減輕將拉出前板部34拉伸並打開之力。 As shown in FIG. 9, the abutting portion 46 of the rack member 44 as the second link member abuts against the protruding portion 26 provided on the side plate 25 of the cabinet 2. In the state where the abutting portion 46 is in contact with the protrusion 26, if the pull-out body 3 is continued to be pulled out, the abutting portion 46 uses the protrusion 26 as a fulcrum to press out the pull-out body 3 to produce an orientation The reaction force near the front side. With this reaction force, the force that stretches and opens the pull-out front plate portion 34 is reduced.

若進而將拉出本體3向近前側繼續拉出，則抵接部46保持抵接於 突起部26之狀態，於收容部4之抵接部插通槽401相對移動。 If the pull-out body 3 is further pulled out to the near side, the abutting portion 46 keeps abutting on the The state of the protruding portion 26 relatively moves in the abutting portion insertion groove 401 of the receiving portion 4.

如圖9所示，於齒條構件44移動至收容部4之後端為止時，滑動板42位於收容部4之前端。於該狀態下，撐條43自收容部4最大限度地向近前側突出，拉出前板部34之傾斜成為最大。 As shown in FIG. 9, when the rack member 44 moves to the rear end of the accommodating portion 4, the sliding plate 42 is located at the front end of the accommodating portion 4. In this state, the stay 43 protrudes to the near side to the maximum from the accommodating portion 4, and the inclination of the drawn-out front plate portion 34 is maximized.

此外，此後亦若需要，只要使用者將拉出本體3向近前側拉出，則拉出本體3於安裝於機櫃2之側板25之軌道5移動。藉此，連同拉出本體3一起向近前拉出。 In addition, if necessary thereafter, as long as the user pulls the pull-out body 3 toward the front side, the pull-out body 3 moves on the rail 5 installed on the side plate 25 of the cabinet 2. Thereby, the body 3 is pulled out together with it.

根據本實施形態，發揮以下之效果。 According to this embodiment, the following effects are exhibited.

根據本實施形態，將拉出構造1設置於具有在內側具備於前後方向延伸之軌道5之一對側板25及於近前側開口之開口部21之機櫃2內，且包含自開口部21***由軌道5引導而可於前後方向移動之拉出本體3而構成。又，於一對側板25之內側設置有朝向拉出本體3突出之一對突起部26。又，拉出本體3包含如下構件而構成：一對拉出側板部33；拉出前板部34，其可旋動地軸支於拉出側板部33之近前側之下端部，且於近前側旋動既定角度而可開閉；及齒輪機構，其設置於拉出側板部33，且藉由連結於拉出前板部34並且與拉出前板部34之移動連動而使可於前後方向移動之滑動板42及撐條43移動，將滑動板42及撐條43之動力傳遞至可於前後方向移動之齒條構件44。又，齒輪機構包含齒輪比可變機構而構成，該齒輪比可變機構係利用藉由將齒條構件44抵接於突起部26產生之反作用力來將拉出本體3向近前側壓出，並且藉由具備齒數不同之至少2個小齒輪而能夠切換齒輪比。 According to the present embodiment, the pull-out structure 1 is provided in a cabinet 2 having a pair of side plates 25 on the inner side with rails 5 extending in the front-rear direction and an opening 21 that opens on the near side, and includes the insertion through the opening 21 The rail 5 guides and is constructed by pulling out the main body 3 which can move in the front-rear direction. In addition, a pair of protrusions 26 protruding toward the pull-out body 3 is provided on the inner side of the pair of side plates 25. In addition, the pull-out body 3 includes the following components: a pair of pull-out side plate portions 33; a pull-out front plate portion 34, which is pivotally pivotally supported at the lower end of the near side of the pull-out side plate portion 33, and is rotated on the near side It can be opened and closed by moving at a predetermined angle; and a gear mechanism, which is provided on the pull-out side plate portion 33, and is connected to the pull-out front plate portion 34 and interlocks with the movement of the pull-out front plate portion 34 to make a sliding plate movable in the front-rear direction 42 and the stay 43 move to transmit the power of the sliding plate 42 and the stay 43 to the rack member 44 that can move in the front-rear direction. In addition, the gear mechanism includes a variable gear ratio mechanism that utilizes the reaction force generated by abutting the rack member 44 against the protrusion 26 to push the pull-out body 3 toward the front side. And by having at least two pinions with different numbers of teeth, the gear ratio can be switched.

根據本實施形態，由於使拉出本體3之齒條構件44之一部分抵接設置於機櫃2之側板25之內面之突起部26，以藉由利用突起部26產生之反作用力將拉出本體3向近前側壓出之方式構成拉出構造1，故可減輕將拉出本體3拉出時之力。另一方面，於減輕將拉出本體3拉出時之力之情形時，必須以使拉 出前板部34不於收納位置自然打開之方式，以齒條構件44(具體而言，是第2齒條齒輪442)限制滑動板42及撐條43之向近前之移動。然而，於在收納位置對齒條構件44之向近前方向之移動施加負載之情形時，由於拉出構造1亦包含齒輪比可變機構，故以如拉出前板部34未自然地打開之小齒輪之齒輪比，自收納位置將拉出本體3拉出之後，可切換齒輪比，使滑動板42及撐條43向前方移動時所施加之負載變更得較輕。因此，能夠將拉出本體3以更小之力拉出。 According to this embodiment, since a part of the rack member 44 of the pull-out body 3 abuts against the protrusion 26 provided on the inner surface of the side plate 25 of the cabinet 2, the body is pulled out by the reaction force generated by the protrusion 26 3 is pushed out to the near side to form the pull-out structure 1, so the force when pulling out the pull-out body 3 can be reduced. On the other hand, when reducing the force when pulling out the main body 3, it is necessary to In such a way that the front exit plate portion 34 does not naturally open at the storage position, the rack member 44 (specifically, the second rack gear 442) restricts the forward movement of the sliding plate 42 and the stay 43. However, when a load is applied to the movement of the rack member 44 in the forward direction at the storage position, since the pull-out structure 1 also includes a gear ratio variable mechanism, it is as small as the pull-out front plate portion 34 does not open naturally. The gear ratio of the gears can be switched after the pull-out body 3 is pulled out from the storage position, so that the load applied when the sliding plate 42 and the stay 43 move forward is changed to be lighter. Therefore, the pull-out body 3 can be pulled out with a smaller force.

根據本實施形態，齒輪機構包含如下構件而構成：第1齒條齒輪421，其構成第1連桿構件(滑動板42及撐條43)；第2齒條齒輪442，其形成於第2連桿構件(齒條構件44)；大齒輪451，其與第2齒條齒輪442嚙合且可旋轉；小齒輪452，其與第1齒條齒輪421嚙合，並且與大齒輪451同軸且可一體旋轉地設置，齒數較大齒輪451少；及第3齒條齒輪443，其相對第2齒條齒輪442，於大齒輪451及小齒輪452之軸向錯開配置並且於前後方向亦錯開配置，且與小齒輪452嚙合。又，藉由將第2齒條齒輪442與第3齒條齒輪443配置於構成第2連桿構件(齒條構件44)之一個齒條構件上而構成齒輪比可變機構。又，以進行第2齒條齒輪442及大齒輪451之嚙合與第3齒條齒輪443及小齒輪452之嚙合之切換之方式構成。 According to this embodiment, the gear mechanism includes the following components: the first rack gear 421, which constitutes the first link member (slide plate 42 and the stay 43); the second rack gear 442, which is formed in the second gear Lever member (rack member 44); large gear 451, which meshes with the second rack gear 442 and is rotatable; pinion 452, which meshes with the first rack gear 421, and is coaxial and integrally rotatable with the large gear 451 And the third rack and pinion 443, which is offset from the second rack and pinion 442 in the axial direction of the large gear 451 and the small gear 452, and also offset in the front and rear directions, and the third rack and pinion 443 is offset from the second rack and pinion 442. The pinion 452 meshes. In addition, the gear ratio variable mechanism is constructed by arranging the second rack gear 442 and the third rack gear 443 on one rack member constituting the second link member (rack member 44). In addition, it is configured to switch between the meshing of the second rack gear 442 and the large gear 451 and the meshing of the third rack gear 443 and the pinion 452.

根據本實施形態，於齒輪機構設置同軸且齒數不同之2個齒輪，並且於齒條構件44設置第2齒條齒輪442與第3齒條齒輪443，將第3齒條齒輪443相對第2齒條齒輪442，於齒輪之軸向錯開配置並且於前後方向亦錯開配置。藉此，可不變更齒條構件44之寬度或長度等外形，設置齒輪比可變機構。因此，可容易地減小打開拉出本體3之力，發揮與上述相同之效果。 According to this embodiment, two coaxial gears with different numbers of teeth are provided in the gear mechanism, and the second rack gear 442 and the third rack gear 443 are provided on the rack member 44, and the third rack gear 443 is opposed to the second tooth The pinion 442 is staggered in the axial direction of the gear and also staggered in the front and rear direction. Thereby, it is possible to provide a gear ratio variable mechanism without changing the outer shape such as the width or length of the rack member 44. Therefore, the force to open and pull out the main body 3 can be easily reduced, and the same effect as described above can be exerted.

根據本實施形態，使設置於一對側板25之內側且壓入至機櫃2內之拉出本體3進而包含藉由經由油壓阻尼器之拉伸彈簧52之彈力而拉入之閉合器機構而構成。根據本實施形態，由於拉出本體3藉由拉伸彈簧52拉伸，向機 櫃2之裡側施力，故於收納拉出本體3時，可一邊使用拉伸彈簧52之力，一邊利用油壓阻尼器使減速速度衰減一邊壓回至機櫃2內部。另一方面，於將拉出本體3拉出之情形時，雖必須利用超過拉伸彈簧52之施力之力將拉出本體3拉出，但齒輪機構具有抵接設置於機櫃2之側板25之內面之突起部26而產生反作用力之抵接部及齒輪比可變機構，故即使設置拉伸彈簧52，亦可容易地減小打開拉出本體3之力，發揮與上述相同之效果。 According to this embodiment, the pull-out body 3, which is provided inside the pair of side plates 25 and is pressed into the cabinet 2, further includes a closure mechanism that is pulled in by the elastic force of the tension spring 52 of the hydraulic damper. constitute. According to this embodiment, since the main body 3 is pulled out by the tension spring 52, it is moved toward the machine The inner side of the cabinet 2 applies force, so when the main body 3 is stored and pulled out, the force of the tension spring 52 can be used while the deceleration speed is attenuated by a hydraulic damper, and the body 3 can be pressed back into the cabinet 2 at the same time. On the other hand, when the pull-out body 3 is pulled out, although the pull-out body 3 must be pulled out with a force that exceeds the force of the tension spring 52, the gear mechanism has a side plate 25 that abuts against the cabinet 2 The protruding portion 26 on the inner surface generates the reaction force and the gear ratio variable mechanism. Therefore, even if the tension spring 52 is provided, the force to open and pull out the main body 3 can be easily reduced, and the same effect as the above is achieved. .

此外，本發明並不限定於上述實施形態，可達成本發明之目的之範圍內之變形、改良等包含於本發明。 In addition, the present invention is not limited to the above-mentioned embodiments, and modifications, improvements, etc. within the scope of achieving the purpose of the present invention are included in the present invention.
