Description

200840941 IX. Description of the Invention: [Technical Field 3 of the Invention] The present invention relates to a compressor element, and in particular to a portable compressor unit. 5 [Prior Art] Background Art A variety of compressors exist in the prior art. Some existing air compressors are portable and generally include: an air storage tank that typically includes one or two air reservoirs for storing compressed air; a wheel 10, relative to the longitudinal direction of the storage tank In terms of the axis, the wheel is located at one end of the air storage tank; and a handle is located at an opposite end of the air storage tank. Compressors with two air reservoirs typically use one wheel, while compressors with a single reservoir typically use two wheels. The single reservoir type and dual reservoir type compressors are commonly referred to as trolley type compression machines. The compressor also includes components for compressing air. These components typically include motor components and pump components. Due to space constraints, these components are typically mounted on top of the air storage tank. An example of such a compressor is

Manufactured by Campbell Hausfeld, model number GP90135, as shown in Figure 12. Mounting the components on top of the air storage tank has a number of disadvantages. 20 One disadvantage is that installing these components on top of the air storage tank will result in a higher center of gravity. A higher center of gravity is particularly inconvenient for the user to manually move the compressor, and may also result in the user losing control of the compressor. This is especially true for the dual-reservoir type trolley-type compressors used in applications where it is often necessary to move up and down on narrow wooden slopes in the form of a trolley, 5 200840941. In addition, the higher use % is prone to tipping or tilting. Moreover, this (four) reduction machine may be difficult to package, store or retail. After packaging, the compressors in Yuruhang usually have higher porches (also now

If the compressor is transported in a larger container, the pressure H is similarly the number of individual compressors that can be loaded into the container. Moreover, the second will limit the higher height of the wagon, which requires a large amount of packaging materials. Due to compression: when storing the compressor, the handle on the existing storage tank is also 4 ^ sleep =. The handle on the compressor is turned on and out from the compressor. The structure of the war will increase the height and length, requiring more storage space and more packaging materials.

The novel compressor has an air storage tank comprising at least one air reservoir 4 for storing compressed gas, preferably comprising two operating reservoirs 4. Referring to Figures 1 and 2, each air reservoir includes an upright 23, two side portions, an outer portion 24 and an inner portion 21, and a bottom portion 8. ^ ^. The air reservoir 4 is attached to the base 6 and is positioned such that the longitudinal line 7 of each reservoir is substantially parallel to the horizontal plane 9 on which the air compressor is placed. The sub-units 4 stored in the %1 are preferably located on opposite sides of the base 6. 12 200840941 The base may be a single base or, alternatively, as shown in Figure 3, the base is a multi-turn assembly. As shown in a preferred embodiment, the base may include a support such as a wire on the bottom 8 of each of the gas storage ports.

10 15

20 and bracket 6b. In another embodiment, as shown in the % diagram, the base need not include a support such as ' but may include a plurality of protrusions 78. In still another implementation: the base can include a bracket, a weldment, a tubular member, or the like. In these embodiments, the 'air reservoir 4' and its retractor components are mounted by projections, weldments or tubular members, or by projections, brackets, weldments or official members. The rhyme can be connected to the inner side portion 21 of the air reservoir 4. In a preferred embodiment, the base further includes a recess, the recess 1 being a through hole in the base. The groove 1G accommodates the fly (four), and thus, the compressor can be placed on the seat in a manner that can be contoured. That is, the portion of the flywheel 12 can pass through the concave _. The air storage means are placed on the base 6 so as to have a space 之间 between the air reservoirs 4. The other components of the air compressor are cut between the reservoirs on the - part of the neutral and the base, which will be described below. The handle member 16 is coupled to the first portion of the at least one air reservoir 4: The member 26 is coupled to the second portion 2 of the at least one air reservoir 4. : I = minute 18 and second part 2G are the left and right portions of the midpoint of the length of the memory 4 respectively indicated by _ in Fig. 1. = Hidden Figure 3 shows the handles and rims mounted directly to the air reservoir 4, but in an alternative embodiment, the handle elements and wheels 4 need not be directly connected to the money reservoir. Preferably, the handle 13 200840941 hand member includes two handles 22, each of which extends outwardly from the first file 18 of the air reservoir 4 and is coupled to the outer portion 24 of each air reservoir 4. More preferably, as shown in Fig. 1, in addition to the end 28 of each handle 22, the handle 22 is substantially parallel to the horizontal plane 9, and the end 28 can be inclined 5 degrees toward the horizontal plane 9 to conform to the ergonomics. learn. Alternatively, the end 28 of each handle includes a handle 3G for the user to grip the handle & the rim member 26 includes a wheel 28 on which the wheel 28 is mounted, and the female bracket 32 connects the wheel 28 Because of the presence of the handle element, the wheel element need not be directly mounted to the air reservoir. As described above, the wheel element is coupled to the second portion 20 of the air reservoir 4, the second portion 20 Opposite the first portion 18, the maker can then hold the handle and move the air compressor so that the air compressor rolls through the wheel. The structure of the jade compressor is called "cart, air" compressor. A compressor component 15 for compressing the gas stored in the air reservoir is coupled to the air reservoir and is typically located within the space between the air storage tanks and supported by the base. The compressor component can include a pump element 36 and a motor component 38. Motor component 38 may include an electric machine or an internal combustion engine. Further, depending on the design of the electrical component, an embodiment including an internal combustion engine may also include a fuel tank 40. A flywheel 12 is coupled to the motor component. Pump element % pack 2〇 pump 36a. Pump element 36 is fluidly connected to air reservoir 4 and motor element 38 is coupled to pump element 36. Additionally, as described above, the flywheel 12 is disposed such that at least a portion is located within the recess. The compressor component can be located anywhere along the base in the space. In a preferred embodiment, the motor can be located about four inches behind the 14 200840941 wheel in the space. In another embodiment, the fruit may be located directly behind the wheel in the space. The compressor member 34 is disposed on the base 6 between the air reservoirs 4 such that the center of gravity of the air compressor is lower than the center of gravity of the prior art air-to-air compressor, and more preferably, The center of gravity of the new air compressor is lower than the highest surface 27 of the air reservoir. As shown in the top, ninth, and ίο, the highest surface of the air reservoir is the portion of the top portion, and when measured at the normal working position, the highest surface (10) is the highest portion of the reservoir from the ground. . For an air reservoir 4, typically a cylindrical reservoir having a generally circular 10-shaped cross-section, the highest surface 27 is generally determined by a tangent to the cross-section labeled τ in Figure 9 and Figure 1 . In normal operating conditions, the tangent is the furthest distance from the ground. Referring now to Figures 9 through 4, in another embodiment, the advantages of the present invention may be realized based on the placement of the bottommost portions 37, 39 of the pump 36a and the motor 38a relative to the position 15 of the air reservoir 4. When measured at their normal working position, the bottommost portion is divided into the lowermost portion of the pump and motor from the ground. Referring to Fig. 10, Fig. 10 shows a circular cross section of the air reservoir 4, the reservoir being divided into a plurality of quadrants: uppermost quadrant 70, upper middle quadrant 72, lower middle quadrant 74 and lowermost quadrant 76. Preferably, the bottommost portion 37' 39 of the pump 36a and the motor 38a are not higher than the uppermost quadrant 7 of the air reservoir 4, respectively. More preferably, in the ascending order: the bottom portions 37, 39 of the pump 36a and the motor 38a are not higher than the upper middle quadrant 72; the pump 3 and the bottommost portions 37, 39 of the motor 38a are not higher than Lower quadrant 74; and most preferably, bottom portions 37, 39 of said pump 36 & and motor 38a are no higher than the lowermost quadrant. In an embodiment that does not include an air_cash_1 with a 200840941 - (4) form, the memory can still be similarly divided into multiple quadrants. Unlike the embodiment described in the attack, prior art air compressors such as the Campbell Hausfeld model 〇?9〇135 compressor (Fig. 12) typically install air compressor components in the air reservoir. The upper part causes the air compressor to have a higher center of gravity. The higher center of gravity is liable to cause instability of the empty milk compressor, so that the pressure is more tolerated or tilted. In particular, when the field is privately moved, it is inconvenient for the user to move the compressor. The pump and motor components of the air compressor of the present invention are located on the base 6 between the air reservoirs 10, which are opposite to the upper portion of the air reservoir, so that the height of the money is lowered, and the center of gravity is lowered. . The reduction in the vertical height of the compressor allows the stability of the compressor to be increased, further preventing I from tipping over or tilting. Preferably, as described above, the center of gravity is below the take-up surface of the air storage weir. In another embodiment, as also described above, excellent, t makes the bottommost portion of the pump and the motor not higher than the air Φ (5) takes the upper quadrant. Each of the embodiments is greatly reduced when The possibility of tipping or tilting the air compressor while moving, and making the movement of the compressor more convenient. Alternatively, in order to further increase the stability of the air compressor, the wheel 28 of the compressor can be increased to be equal to or greater than the air compressor wheel size* Figure 1. Compared to a compressor having a smaller wheel, the amount of rotation required to pivot about the center axis for lifting the compressor with the handle member is reduced. Advantageously, the amount of rotation ... the force exerted on the user's arm is smaller and more convenient for the user 16 200840941 The compressor is moved over the uneven terrain by the wheels. Moreover, the arrangement of the air compressor components on the base will make the height or profile of the two-gas compressor lower than that of the prior art compressors and wheels compared to the horizontal plane, which is advantageous for the shipping and packaging of the air compressor. Height wheel 5 gallery = the lower the packaging material. Moreover, when packaging, the lower the porch, the smaller the storage. When packaged, air compressors are typically stacked on top of each other on a shelf for storage or display. With a smaller profile, it is particularly advantageous to have more of a single compressor to transport the C compressor on top of each other in the two compartments. Freight is usually carried out by using 10 large containers that are transported on ships, trains or trucks. The lower profile allows more compressors to be placed in the set box, thus reducing the freight. 15 Figures 4 and 5 show another embodiment of the air compressor, which is shown in Figure 3 to Figure 3. The described embodiments are similar in that the same elements have the same numbers. The embodiment as described in Figures 1 to 3, the air compressor comprises at least one air reservoir 4, preferably two air reservoirs 4. Moreover, the compressor component, the base, the handle member and the wheel member are the same as those described in the figures to Fig. 3, and the same numerals are used. 20... However, at least one air is stored on the base relative to the longitudinal axis 7 of the air reservoir. Thus, the air reservoir has an angle with respect to the central axis 44 passing the wheel 26, and thus the central axis is sacrificed to It is substantially perpendicular to the axis of rotation of the wheel. Preferably, the reservoir 4 is set to an angle «, and the angle α of the angle 42' in Fig. 4 is in the range of 15 to $ degrees. In other embodiments of the 2008 200840941, the angle value of the angle α may be smaller or larger depending on design requirements. Since the air reservoir is angled, the width of the compressor 2 near the wheel member 26 is less than the width of the remainder of the air compressor in the direction toward the handle member, which width gradually increases toward the handle member 16. 5 Pump element 36 and motor element 38 are at least partially disposed on a top portion 23 of one of said air reservoirs 4 and are arranged such that when viewed in Figure 4, the side turns of these air compressor components are substantially parallel to said air storage The longitudinal axis of the device 7. The side turns are substantially parallel to the longitudinal axis of the air reservoir, leaving a space 10 for the flywheel 12 to be placed in the space 14 and connected to the base 6. The space 14 is sufficient to accommodate various sizes The flywheel, therefore, the larger size of the flywheel does not need to be placed on the reservoir. Therefore, preferably, the larger flywheel does not increase the height of the compressor in a large degree of privacy, thereby avoiding a compressor with a higher profile The above disadvantages are produced. Although not essential, the present embodiment preferably prepares a flywheel disclosed in the embodiment 1S larger than that shown in Figs. 1 to 3, as shown in Fig. 5. The flywheel 12 may be covered by the housing 46. As described above, the base may include a recess 10 for partially accommodating the flywheel. The air compressor of the present embodiment centers the compressor as in the above-described manner. It is lower than the center of gravity of the compressor of the prior art. This is because the current 20-seat air (four) retracting machine usually installs the flywheel on the upper part of the storage device, thereby increasing the center of gravity by two. Moreover, at least one air storage device is formed. - setting the angle so that the profile of the air compressor has a lower profile than the compressor of the prior art due to the reduction of the flywheel, thereby having the additional packaging advantages described above. In the case of the scope of the present invention, the above embodiment may Knots 18 200840941 in combination with other features. One of the features includes a secret handle 22 adapted to the user by folding the machine and conforming to the human body; the hand and wheel elements (4) 5 10 15 In addition, the movable handle 22 can be stored, so that the handle is convenient for storage. The removable pure hand can be rotated, folded, slid, folded or shrunk 'to facilitate the human body In addition, the movable handle can be detached. The detachable handle can be stored in a separate position on the (4) machine. Referring to Figures 6 and 7, each handle 22 of the handle member The connector 48 can be read by the connector 48. ", her hand can be of a type that allows movement around the horizontal axis and/or vertical, or alternatively, the connector 48 can include freedom to allow no angle limitation. Sporting U connector. Preferably, the joint is attached to the outer portion 24 or the top 23 of the air reservoir. Alternatively, the connector 48 and the handle 22 can be (10) of the memory. The handles and handles can be mounted in any of the embodiments described herein, but this alternative embodiment is particularly preferred for the embodiments of Figures 4 and 5. In another embodiment, the joint and handle can be attached to the base 8. The handle 22 can be rotated, as indicated by the ridge R, so that the handle can be stored in parallel and close to the reservoir (four) (shown by the dashed line 22a in Figure 6). * In still another embodiment, each handle can be modified to be slidably movable. Referring to Fig. 7, the sleeve 50 is mounted to the first portion of the air reservoir and can be mounted on any of the outer portion 24, the top portion 23, the bottom portion 8, or the inner side portion 21 of the air reservoir. The handle 22 is slidably engaged with the sleeve 5 。. When the locking member 52 is released, the handle 22 can be freely moved within the sleeve 50, 浐 = 19 200840941 to facilitate the contraction of the handle. In a preferred embodiment, the locking member 52 includes a hole 54 in the handle and a hole 56 in the sleeve 50. When the holes are aligned, a pin 58 can be inserted into the hole to prevent the handle from moving within the sleeve. Preferably, a plurality of holes can be provided along the handle so that the handle can be locked in a plurality of positions relative to the sleeve. As shown in Fig. 7, the handle 22b is detachable from the first end % of the sleeve 5 , and inserted into the second end 68 of the sleeve so that the handle 22b does not protrude outward from the air reservoir . Further, as shown in Fig. 7a, the handle 22b can be completely inserted into the sleeve 5''. Preferably, these locations reduce the size of the two compartments in which the compressor is stored, as well as the amount of packaging required for shipping and storage prior to sale. Alternatively, the stop on the handle prevents the handle from escaping from the sleeve. Alternatively, the sleeve 50 can be incorporated into the joint 48 such that the handle can be rotated or telescoped.

15 In another embodiment of the embodiment shown in FIG. 7 - each handle 22c may comprise

20^ nested portions 80, in contrast to the 7a-th, the filaments are allowed to telescope by folding or backing each other, while in the %th view the handles can be slid into or out of the sleeve 50. The nesting (10) can be partially nested so that not all nested parts are collapsed or completely nested. A brake or other release mechanism can be incorporated to selectively hold the nested portion in a nested or partial position. Moreover, the nesting handle can be detached, and thus, the handle* as described above can be suspended (four). The movable handle has several advantages. The handle can be rotated or telescoped 'and thus does not protrude outwardly from the first portion of the compressor, thereby making the air compressor compact, as is the shipping, storage and packaging of the 2008 20081941 as described above. Advantages. Moreover, the handle is easily adjusted to a plurality of positions to be more suitable for the user. In fact, it will be apparent to those skilled in the art that the handle can be modified to either retract or rotate as described above. Referring to Fig. 8, each of the reservoirs 4 may include a slider 60 which is connected to the bottom 8 of the reservoir 4. The slide 60 facilitates the sliding of the air compressor, which is useful in certain situations. For example, the slider can be used when the compressor is mounted at the rear 4 of the vehicle, or in other cases where it is not convenient to use the wheel member to move the pressure _, (4). Specifically, when the pressure-reducing shaft is lifted upward to be loaded into the rear of the vehicle (e.g., the flat panel of a light truck), the slider can be used to slide the compressor once the slider is in point contact with the rear edge of the vehicle. The slide is preferably made of a material that assists in sliding, such as an elastic material. Although the slider preferably extends across substantially the entire bottom 8, in an alternative form, the slide extends less than the entire length of the bottom. Moreover, in another embodiment, the skateboard may be made of a plurality of pieces of material that may or may not be continuous, the pieces of material spanning the bottom 8 of the air reservoir. connection. Alternatively, the air compressor may include a secondary handle 62 disposed on the air reservoir 4. The secondary handle 62 helps to lift the compressor. Preferably, the pair 20 handle 62 is a club-type handle, as shown in Figure 8, and can also be used to protect the compressor components if the compressor is tipped over. However, in another embodiment, the field handle 62 may have other shapes and does not have advantages depending on its shape. Preferably, each of the secondary handle portions is disposed on the top 23 of each of the air storage pockets, although in other embodiments, the secondary handles are disposed in other manners in the manner of 21 200840941. For example, at least one sub-handle can be placed on each of the reservoirs. Moreover, the secondary handle can be disposed on the outer portion 24 of the air reservoir. Alternatively, the handle 64 can be placed on the handle to further facilitate the lifting of the compressor. 5 Preferably, the sub-handles are offset from each other, and thus, the handle 62a provided on the second portion 2A is shorter than the handle 62b provided on the first portion 18. In a preferred embodiment, the offset is about 3.875 inches, but in other embodiments, the offset can be greater or less than the number. However, a handle having a height difference due to manufacturing tolerances (i.e., a handle that is not intended to be offset) is not a sub-handle. The handles are manufactured to a tolerance of less than 3/4 of an inch and are typically close to 1/4 inch. Therefore, if each of the secondary handles is used to lift the air compressor, the second portion 2G is lifted higher than the first portion 18, which helps to pressurize the air - _ loading the truck or other vehicle_back. When the (4) handle and the skateboard are both: 15 (four) 'loading the compressor is particularly convenient (for example, the compressor is loaded with a light truck • the touch part). Specifically, when the temple is elevated, the second portion 20 is higher than the first portion 18. The operator can then easily place the sled 6 on the underside 25 of the second portion 20 on the truck bed and easily slide the compressor into the truck. In another preferred embodiment, referring to Fig. 13, the sub-handles 62a, 62b 2 are disposed relative to the center of gravity of the compressor (indicated as CG). The sub-handle, (4) may be provided on the air reservoir as described in the above embodiment. The first sub-handle 62a is located at a horizontal distance from the center of gravity CG, and the second sub-handle (four) is at a distance. The CG distance is for you.
